+
+
+When Pasteur died a remarkable article appeared in one of the Paris
+newspapers. The writer described the intimate routine of the life at the
+Pasteur Institute, and compared it with that of a mediæval religious
+community. A little body of men, forsaking the world and the things of
+the world, had gathered together under the compulsion of a great idea.
+They had given up the rivalries and personal interests of ordinary men,
+and, sharing their goods and their work, they lived in austere devotion
+to science, finding no sacrifice of health or money, or of what men call
+pleasure, too great for the common object. Rumours of war and peace,
+echoes of the turmoil of politics and religion, passed unheeded over
+their monastic seclusion; but if there came news of a strange disease in
+China or Peru, a scientific emissary was ready with his microscope and
+his tubes to serve as a missionary of the new knowledge and the new hope
+that Pasteur had brought to suffering humanity. The adventurous exploits
+and the patient vigils of this new Order have brought about a revolution
+in our knowledge of disease, and there seems no limit to the triumphs
+that will come from the parent Institute in Paris and from its many
+daughters in other cities.
+
+Élie Metchnikoff, now Professor at the Pasteur Institute in Paris, is
+one of the most distinguished of the disciples who left all else to
+follow Pasteur. He was born on the third (16) May, 1845, in a village of
+the Government of Kharkoff (Little Russia). He was educated at the
+Gymnasium and the University of Kharkoff, passing through the Faculty of
+Science. From 1864 to 1870 he worked at Zoology at Giessen, Göttingen
+and Munich, successively under three well-known zoologists, Leuckhart,
+Henle and Von Siebold, and was then appointed Professor of Zoology and
+Comparative Anatomy at Odessa. He made expeditions to Madeira, Teneriffe
+and the Kalmuck Steppes in connection with his zoological researches. In
+1882, in consequence of administrative difficulties, arising as part of
+the troubles that followed the murder of the Tzar, Alexander II., he
+resigned the Professorship and became Director of the municipal
+Bacteriological Laboratory. In 1888 he went to the Pasteur Institute,
+and has remained there since that time.
+
+The earlier part of Metchnikoff’s career was devoted to Zoology, and
+chiefly to investigation of the embryological history of the lower
+invertebrates, and the sequence of his discoveries should afford food
+for reflection to those Baconian economists who are unwilling to shelter
+any tree of knowledge that does not give immediate promise of marketable
+fruit. The labour of many years spent in minute tracing of the
+development of insects, echinoderms, worms and jellyfish, would appear
+sufficiently unprofitable to those who give a scanty support to Botany
+as the provider of drugs, who tolerate Chemistry because it has supplied
+aniline dyes, and who patronise the physical sciences from a lively
+sense of the convenience of telephones and telegraphs. And yet from
+these remote, inhuman interests, Metchnikoff, without intellectual
+transition, passed directly to results affecting vitally the human race,
+and became one of the high priests of Bacteriology and a guardian of the
+Pandora’s box of modern times.
+
+From observations made originally on water-fleas, he was led to discover
+the functions of the white corpuscles of human blood. He showed by what
+mechanism these made perpetual war against the intruding microbes of
+disease, and he laid the foundations of knowledge as to the agencies
+that weaken and the modes of strengthening these guardians of our
+health. In a series of investigations into the phenomena of inflammation
+in men and lower animals, he carried his observations into new fields,
+and explained the relations of the white corpuscles to the juices that
+attract and repel them (chemotaxis). It was he, for instance, who
+discovered that these corpuscles, under certain circumstances, migrate
+into the hairs and absorb and remove the pigment, so producing the
+blanching of old age. Although popularly the most interesting this was
+far from being the most important of the changes of senile decay that he
+found to be due to the activity of the wandering cells of the body. And,
+as will be seen in the present volume, the actions and interactions of
+the bacteria harboured in the body, the white corpuscles that are a
+natural part of the body, and the various juices or serums produced
+naturally or introduced by accident or design, are concerned in life
+itself and the decay of life.
+
+Metchnikoff is an expert of experts in the science of life, and has
+gained the right to a hearing by forty years of patient devotion and
+brilliant research. In the volume that he has now given to the public,
+he has addressed himself to the gravest and the most serious problems of
+humanity, to life and sex and death and the fear of death. From the
+earliest days when man could spare time from the satisfaction of his
+immediate wants to reflect upon his nature and destiny, these problems
+and the invention of fantastic solutions or evasive anodynes have
+absorbed his attention. The folklore and philosophy, the religion and
+poetry of all races and of all stages of culture, from savage barbarism
+to decadent refinement, revolve round these obsessions of the mind, and,
+as Metchnikoff most plainly shows, no enduring comfort has yet been
+found. Now for the first time in the history of thought, the exact
+methods of science have been brought to the statement of the problems.
+
+In revising this translation of Metchnikoff’s book for the
+English-speaking public I have had to content myself with seeing that
+the plain meaning of the French was transformed to plain English, and
+that references to French editions were changed, so far as was possible,
+to corresponding references to English editions. Some of the phrases
+that recur were difficult to express. “Human nature” for instance is not
+an exact equivalent of _la nature humaine_, for the latter phrase has a
+complete significance, and very definitely implies not only the mental
+qualities of man, but his bodily framework, with its inherited and
+acquired anatomical structure and physiological functions. The phrase
+“human constitution,” especially in the common medical sense, carries
+more of the meaning, and I have used it occasionally. The word “harmony”
+means harmony with the environment, and disharmony is want of harmony or
+imperfect adaptation to the existing environment. In the case of the
+human organism, which has passed through profound changes at a rate
+prodigious in the history of evolution, many parts of the constitution
+are no longer in gear with the existing environment, and it is in such
+disharmonies that Metchnikoff finds the source of the troubles that have
+perplexed mankind.
+
+In several parts of this volume, and particularly in the chapter dealing
+with disharmonies in the reproductive functions, there is much plain
+speaking on matters that modern civilisation attempts to conceal. I have
+not had the impertinence to suppress or to alter a line or a word of
+these pages. They are written in high seriousness on fundamental facts
+of the constitution of man; they relate to problems and difficulties
+that every age in the history of man has had to face, and that are dealt
+with in the plainest language in the books of all the religions. For the
+first time proper knowledge has been brought to the task, and it is to
+be remembered that this volume is an attempt to explain mysteries of the
+flesh and of the spirit of which all existing explanations have failed
+to satisfy humanity. The volume is avowedly no more than a preliminary
+statement, a rallying-point for the work of future generations. But it
+awakens a new hope for humanity now that the old are fallen dumb; as
+Metchnikoff himself says, “If it be true that man cannot live without
+faith, this volume, when the age of faith seemed gone by, has provided a
+new faith, that in the all-powerfulness of science.” In every country,
+the new Order of priests of science, in the vigils of the laboratory, is
+working for the future of humanity.

+                                PREFACE
+
+
+In offering this book to you, reader, I feel that I must justify its
+publication. I admit freely that more could be said for a finished study
+in which hypotheses were replaced by exact fact. But to get together
+assured results in a field so little explored is a great task, calling
+for time and much labour.
+
+I remembered the adage, “_Ars longa, vita brevis_,” and I decided to
+publish what is really a programme of work to be carried out as fully as
+circumstances may permit. At all events, I hope that such a programme
+may have its value for younger investigators, who wish a point of
+orientation for their labours.
+
+My book is addressed to disciplined minds, and in especial to
+biologists. As I wrote it, I had not the general public in my mind, and
+so I did not hesitate to devote nearly the whole of a chapter to
+“disharmonies in the apparatus of reproduction.” I see in that apparatus
+the clearest proof of the essential disharmony in the organisation of
+man.
+
+I have to thank those friends who were familiar with my views and whose
+advice and assistance have helped me to develop them.
+
+In particular, I desire to thank my friends Dr. E. Roux, who was at the
+pains to make my French more French; and Dr. J. Goldschmidt and Dr.
+Mesnil, who have read and revised the proof-sheets.

+                SUMMARY OF OPINIONS ON THE NATURE OF MAN
+
+
+  Importance of the study of the nature of man—The nature of man as the
+  foundation of morality—Greek worship of human nature—Matriopathy of
+  ancient philosophers—Rationalism of the eighteenth and nineteenth
+  centuries—Degradation of human nature by religious doctrines—Influence
+  of these conceptions on actual life and on art—Reaction of the
+  Reformation against the degradation of human nature—Mutilation of the
+  human body by primitive races
+
+
+Notwithstanding the real advance made by science, expressions of
+discontentment with it are familiar. Science, it is said, no doubt has
+ameliorated the material conditions of human life, but is powerless to
+solve those moral and philosophical questions that interest cultured
+people so deeply. In this region science has done no more than to
+destroy the foundations of religion. It has robbed mankind of the
+consolations of religion without being able to replace them with
+anything more exact or more enduring.
+
+It cannot be disputed that a general uneasiness disturbs the world of
+to-day. Although his environment is most favourable to the fulfilment of
+many of his capacities, man finds himself without orientation when he
+has to determine the course of his life, or to explain to himself his
+true relation to such categories of humanity as family, nation, race and
+human race. This uneasiness reveals itself as discontentment, and it
+leads to pessimism or to mysticism. Most of the philosophical systems of
+the nineteenth century were steeped in melancholy, and led straight to a
+denial of the possibility of happiness and even to an advocacy of
+extinction. The frequency of suicide has increased greatly among all the
+civilised peoples. There is no need to tabulate proofs of a notorious
+fact.[1]
+
+A remedy for this malady of the age has been sought in the attempt to
+restore religious and mystical faith. On all sides have sprung up
+efforts to found new religions or to amend the old. Many defenders of
+science have gone the length of admitting its incapacity to solve the
+problem of the existence of man; they have held that that problem was
+insoluble for the human mind. Such a depressing conclusion has been
+formulated in spite of many attempts to reach a rational conception of
+the universe and of man.
+
+It is no new thing to ask if there be nothing but faith to control human
+conduct and to lead mankind towards universal happiness. Men of science
+and philosophers, in many ages, have thought that human nature itself
+could provide all the materials for a rational morality.
+
+In the ancient world and, above all, among the Greeks, human nature was
+held in high esteem. The Oriental races, predecessors of the Greeks in
+civilisation, generally represented their gods as fantastic or grotesque
+beings, composites of men and animals. The Greeks made gods in their own
+image, giving them all the most beautiful qualities of the human race.
+Such a conception was a dominant factor in ancient Greek life and
+civilisation. The adoration of Man embraced the human body, and led to
+the despising of every mode of tampering with the natural body. Thus,
+for instance, shaving[2] of the face was regarded as a humiliation, for
+a smooth chin gave an unnatural, womanish cast to the face of a man.
+
+The adoration of human nature by the Greeks appeared in Greek plastic
+art, and was the cause of its excellence. The ideal of art was to copy,
+in the most faithful way, the most perfect example of the human body,
+and Greek artists made measurements of the body so accurately that
+modern science has confirmed their chief results.[3] As sculpture most
+completely realised the Greek ideal of the human body, it became almost
+a national art among the Greeks.
+
+Greek philosophy had an equally high opinion of human nature, of the
+human body, and of representations of the human body. Just as Greek art
+aimed at the presentation of the body of man, so Greek philosophy
+proclaimed the nobility of all human qualities, and inculcated the
+doctrine of a harmonious development of all sides of human nature.[4]
+Such a doctrine was formulated by Plato, and became a fundamental
+principle of the Old Academy; the New Academy assumed it, and handed it
+on to the Sceptics. According to Xenocrates (fourth century), who
+belonged to the Old Academy, happiness consisted not only in the
+possession of human virtue, but in the accomplishment of all natural
+acts.[5]
+
+The principle of a worship of human nature is in itself rather vague,
+and it is not surprising that disputes and contradictions arose in
+relation to its application. Thus Plato excluded pleasure from his
+conception of the good, while Aristotle, Plato’s pupil, held a contrary
+opinion. For the latter pleasure was the natural motive of human action,
+and its attainment was associated as intimately with the perfect life as
+beauty and health were associated with the perfect human body.[6]
+
+Under the name _Matriopathy_ there arose, in the ancient world, a
+doctrine the object of which was the study of the goal of natural
+morality. This doctrine was held by many philosophers, but these applied
+it to the details of actual life in very different fashions. Thus, for
+the Stoics, the _summum bonum_ and happiness, the most lofty aim, could
+not be found except by conforming life to nature. Conduct was to be
+brought into harmony with the rational order of nature in such a fashion
+that every conscious and rational being would perform no actions that
+could not be deduced from the general law.[7] The same principle of a
+life in harmony with nature led the Epicureans to the conclusion that
+“pleasure is a natural good, that is to say, a condition conformable
+with nature, and so bringing with it intrinsic contentment.”[8] Setting
+out from the same fundamental principle, the theories of the Stoics and
+Epicureans led in opposite directions.
+
+The Roman philosophers adopted the principle of a life strictly natural.
+Seneca, for instance,[9] enunciated the maxim: “Take nature as your
+guide, for so reason bids you and advises you; to live happily is to
+live naturally.”
+
+Without following through the centuries the development of the idea in
+detail, I may content myself with saying that resort has been made to
+it, wherever there was sought, outside the sanction of religion, a
+rational principle to guide human conduct. It recurs even among those
+convinced Christians who rebelled against the asceticism and hatred of
+human nature that became prevalent in the early centuries of the
+Christian era.
+
+The Greek conception of a life in harmony with nature found its most
+complete development in the rationalism of the Renaissance, and of the
+centuries that followed it. Hutcheson,[10] a Scotch philosopher of the
+eighteenth century, insisted that right was with the thinkers of the
+naturalistic school, and that the realisation of their ideal was to be
+considered as the highest virtue. He thus placed himself directly
+against the Scotch clergy who asserted the greatest contempt for human
+nature. Buckle[11] proclaimed that it was a high honour for Hutcheson to
+have been the first Scotchman to raise his voice publicly against the
+degrading views of his time.
+
+The French philosophers of the eighteenth century, who sought to replace
+the religious foundations of conduct by rational principles, again had
+recourse to human nature. Not long before the French Revolution there
+appeared a treatise in three volumes, written by Baron d’Holbach, and
+entitled, “Universal Morality, or the Duties of Man based on
+Nature.”[12] Frankly a materialist and atheist, that writer laid it down
+as an axiom that “to be universal, the moral law must be founded on the
+essential nature of man, that is to say, on the properties and qualities
+found constantly in the human being, and that distinguish him from other
+animals.” To be well assured, “morality presumes a science of human
+nature.”[13]
+
+The principle of ancient philosophy reappeared in the works of
+rationalists of the nineteenth century. Wilhelm von Humboldt declared
+that “the ultimate ideal of man, the ideal prescribed for him by the
+irrefutable and eternal laws of reason, consisted in a development as
+harmonious as possible of all his qualities in their entirety.” The
+modern historian, Lecky,[14] defines the aim of life as the full
+development of all that exists in the proportions determined by nature.
+
+Philosophers and historians are not alone in the adoption of Greek
+rationalism. Many naturalists, and among these some very distinguished
+authors, have spoken in the same sense. It is easy to see the Greek
+principle in such phrases as those of Darwin[15] when he wrote: “The
+term general good may be defined as the means by which the greatest
+possible number of individuals can be reared in full vigour and health,
+with all their faculties perfect, under the conditions to which they are
+exposed.”
+
+Georges Seidlitz,[16] an advocate of the great English naturalist, got
+still nearer to the conception of the ancients. According to him, the
+moral and rational life consisted in “the accomplishment of all the
+functions of the body, in due but full proportion.”
+
+Herbert Spencer,[17] in analysing the aim of existence, came to the
+conclusion that morality should be adjusted so as to make life as full
+and complete as possible. As a criterion of physical perfection, the
+English philosopher would accept only the complete devotion of all the
+organs to the accomplishment of all their functions, while his criterion
+of moral perfection was contribution to the general good. These views
+are plainly, if not exactly, expressions of the Greek ideal.
+
+While, then, rational philosophers in all the ages have sought the
+foundation of morality in human nature itself, and have held human
+nature to be good, or even perfect, many religious doctrines have
+displayed a very different view. Human nature was regarded as being
+composed of two hostile elements, a body and a soul. The soul alone was
+to be honoured, while the body was regarded as the vile source of evils.
+Such a view led to the flagellations and torturings of the body which
+form so strange and so widespread a phenomenon. The Hindu fakirs who
+swing themselves on hooks, the dervishes and Mussulman Assouans who beat
+in their skulls with clubs, the Russian Skoptsy who emasculate
+themselves, and many other instances make it plain that natural
+perfection is not taken as the basis for conduct.
+
+Buddha[18] in the clearest way showed his belief that human nature was
+base. Coming out from the apartments of the women, there came to him a
+“vivid idea of the impurity of the body, a feeling of repulsion from it,
+and of blame of it; regarding his own body and seeing its wretchedness,
+he began to despise it, and to formulate conceptions of impurity and
+purity; _from the sole of the feet to the crown of the head, to the
+limit of the brain, he saw that the body was born in impurity, came from
+impurity, and always let itself be drawn to impurity_.” These
+reflections led him to the conclusion: “What wise man, having regarded
+his own body, will not see in it an enemy?”
+
+Towards the end of the old world, the Greek theory of human nature
+yielded to a very different conception. The opposition between the
+opinions of the Stoics on morality, and their admiration of human
+nature, led Seneca, one of the last Roman Stoics and a celebrated
+contemporary of Jesus Christ, to break completely away from the ancient
+doctrine. Convinced of the moral weakness and imperfection of man, and
+of the persisting power of evil, Seneca declared that human nature
+contained a vicious and essentially evil element. This element was
+seated in the body, which he regarded as so essentially vile that it is
+to be despised. Our body was no more than the dwelling of the soul, its
+temporary home, a place in which it cannot be at rest. The body was a
+burden which the soul would be rid of, a prison-house from which it
+would escape. According to Seneca[19] the soul must wrestle with the
+body, for the body brings to it nothing but suffering, while the soul is
+essentially pure and spotless, and as much above the body as divinity is
+above matter.
+
+A dualism still more pronounced was characteristic of the early
+Christian view of human nature, and led to the depreciation of the body
+as compared with the soul. In the fourth and fifth centuries of our era
+such a view was so dominant that a struggle against the material side of
+our nature became a rule of life. The most absolute asceticism spread
+throughout the Christian world.[20] A struggle against hunger, thirst,
+and desire for sleep, rejection of all pleasures that come from
+impressions of sight, of hearing, or of the palate, and, above all,
+abstention from sexual intercourse, became, in the opinion of believers,
+the true aim of human life. The conviction that human nature was
+essentially corrupt led to a declaration of war against it; all the
+pleasures were forbidden, even the most innocent of them being thought
+vicious. What could be more in contrast with the calm and joyous
+philosophy of the Greeks, for whom there did not exist the idea of a
+struggle against the supposed corruption and imperfection of man? The
+dualistic theory made such demands on its proselytes that these,
+absorbed in the salvation of their souls, sank from the physical point
+of view to the level of wild beasts. Hermits resorted to the lairs of
+animals, abandoned their clothing and went about naked with shaggy and
+disordered hair. In Mesopotamia and a part of Syria there arose a sect
+of eaters of grass; these were people who had no dwellings and who ate
+neither bread nor vegetables, but wandered on the hills and fed on the
+herbage. Cleanliness of the body was regarded as an indication of
+corruptness of the soul, and among the most highly venerated of the
+saints were those who took no care of the body. Athanasius relates with
+approval that when St. Antony, the father of monks, became old he never
+washed his feet.[21]
+
+Such doctrines soon brought about a most serious perversion of the
+innate instincts of the human race. The senses of family and of society
+became so weakened that fanatical Christians were more than indifferent
+to their kinsmen and countrymen. One saint was venerated because he was
+hard and cruel only to his relatives. It is told of the Abbot Siseuss
+that on a believer asking to be received into the convent, he inquired
+if the suppliant had any one akin to him. “I have only a son,” said the
+Christian. “Well, then,” said the abbot, “take your son and cast him
+into the river, for thus only may you become a monk.” The father set
+about to do the bidding of the abbot, and it was only at the last moment
+that the order was recalled. For admission into a Christian community it
+was necessary to renounce one’s country.[22]
+
+Such ideas have struck a deep and enduring root. In the opinion of the
+ministers of the Scotch Church of the seventeenth century, according to
+Buckle,[23] there was nothing so surprising as that the earth could
+contain itself in the presence of that horrid spectacle, man, and that
+it did not gape, as in former days, to swallow him in the midst of his
+wickedness. For certainly, in the created universe, there could be
+nothing so monstrous and so horrible as man.
+
+It was to be expected that when such conceptions prevailed, celibacy and
+repudiation of the reproductive instinct should have been made
+obligatory on the clergy. The words, reported by St. Matthew (xix. 11,
+12), that “there be eunuchs who have made themselves eunuchs for the
+kingdom of heaven’s sake” were interpreted by some as implying a
+voluntary renunciation of marriage, while others insisted on the literal
+meaning and in consequence mutilated themselves more or less completely.
+The breasts of women were removed to eradicate the maternal instincts.
+But it is only the sect of Skoptsy, by no means a small body in Russia,
+that applies the gospel command in this stringent fashion. The wish
+announced by St. Paul (Corinthians vii. 7), “I say therefore to the
+unmarried and widows, it is good for them if they abide even as I; but
+if they cannot contain, let them marry, for it is better to marry than
+to burn,” soon became a command, and since the fourth century the
+Catholic Church has advocated celibacy of the clergy, although it was
+not enforced until the eleventh century (under Gregory VII.). A low view
+of human nature has survived in the Catholic Church even to our own
+times. Pope Leo XIII., in his “Encyclical on Freemasons,” proclaimed
+it.[24] “Human nature,” he said, “was contaminated by the Fall, and as
+it is therefore much more prone to vice than to virtue, in order to
+attain virtue it is absolutely necessary to restrain the wild impulses
+of the soul, and to control the appetites by reason.”
+
+Art has reflected the Christian conception of human nature. Sculpture,
+which played so great a part in the ancient world, and which was
+intimately associated with Greek ideals, began to decline rapidly in the
+Christian era. It lasted longer in the Roman Empire of the East, but in
+Italy it was almost completely forgotten by the eighth century. Painting
+survived, but not without undergoing an extraordinary degeneration. All
+the Italian works of art of the Carlovingian period, displayed the
+utmost indifference to natural form, and a loss of the sense of harmony
+and beauty. Later on, Italian art fell lower still. “No one dreamed any
+longer of studying nature or of observing the human body. An epoch in
+which the interference of supernatural forces was generally accepted,
+and in which the conception of the universe was founded on a contrast
+between the natural and the supernatural, could not admit in its art the
+rule of natural law or a natural order of events.”[25]
+
+The intimate connection between the depreciation of human nature due to
+Christian doctrine and the inferiority of the art of the middle ages
+cannot be denied. Taine[26] writes of the period as follows: “If one
+considers the stained-glass windows or the images in the cathedrals, or
+the rude paintings, it appears as if the human race had become
+degenerate and its blood had been impoverished; pale saints, distorted
+martyrs, virgins with flat chests, feet too long and bony hands, hermits
+withered and unsubstantial, Christs that look like crushed and bleeding
+earthworms, processions of figures that are wan, and stiffened, and sad,
+upon whom are stamped all the deformities of misery and all the
+shrinking timidity of the oppressed.”
+
+The art of the middle ages fell lower and lower until the Renaissance,
+with its return to the Greek ideal, brought new vigour. The great
+masters of the Renaissance were in addition scientific men who had
+studied mathematics and who employed the technique of mensuration; such
+were Alberti, Leonardo da Vinci, Michel Angelo, and others. The return
+to the Greek ideals and to nature brought with it the taste for beauty.
+
+When the ancient spirit was born again, its influence reached science
+and even religion, and the Reformation was a defence of human nature.
+The Lutheran doctrines resumed the principle of a “development as
+complete as possible, of all the natural powers” of man, and saw in that
+ideal a guide for humanity. Compulsory celibacy was abolished, and free
+play was given to all the tendencies in conformity with the laws of
+nature.[27]
+
+Besides those whose religion led them to despise the human body, there
+have been many savage races and tribes who have practised mutilations of
+the body. It would be a long list were I to set out all the modes in
+which the human body has been disfigured. Treatises on Ethnography and
+the volumes of travellers contain a multitude of details of this sort.
+The hair, the teeth and the lips have been subjected to treatment with
+the object of making them as unlike the natural condition as is
+possible. Many of the lower races discolour their teeth, or remove some
+of them, or file them to points. Others insert in the lips pieces of
+wood, of stone, or of bone. A whole chapter might be occupied with an
+account of the disfiguring devices of tattooers. The skull, the breasts,
+and the feet, have all been subjected to deforming treatment.
+
+Although there is not enough evidence to set down these practices to the
+existence of definite and self-conscious religious or philosophic
+doctrine, it is at least certain that the people among whom they occur
+are far from revering human nature in the fashion of the Greeks, but
+rather attempt to distort it in accordance with their own taste.
+Discontent with the natural conditions of existence is, as we have seen,
+so widespread that there is good reason for an inquiry as to the
+existence of some general principle underlying this diversity of opinion
+regarding human nature. I have already shown that this question of human
+nature has for long interested mankind, and has shared largely in the
+formation of ideas of the good and the beautiful. It is not too soon to
+submit the problem to rational investigation, using those rigid methods
+of science which have been learned in our epoch. I shall try to give an
+exposition of human nature in its strength and in its weakness. But
+before passing to man, I shall survey the lower forms of life, hoping to
+fix some landmarks that will be useful in the study of the larger
+problem.

+                               CHAPTER II
+       HARMONIES AND DISHARMONIES AMONGST BEINGS INFERIOR TO MAN
+
+
+  The organised world before the appearance of man on the earth—Absence
+  of a law of universal progress—Fertilisation of vanilla—The part
+  played by insects in the fertilisation of orchids—Mechanism by which
+  insects carry the pollen of orchids—Habits of fossorial

+  orchids—Disharmonies in nature—Unadapted insects—Aberration of
+  instincts—Perversion of sexual instinct—Attraction of insects by
+  light—Luminous insects—Law of natural selection—Happiness and
+  unhappiness in the organised world
+
+
+Long before man appeared on the earth animals and plants were
+distributed over it. Some of these were endowed with but vague senses,
+while others had well-developed instincts, and some even a certain
+degree of intelligence which they applied for their self-preservation
+and for the propagation of their own kind.
+
+Many species, well adapted for the resistance of external influences,
+have survived from very early times to the present day. In the
+Carboniferous period birds and mammals did not yet exist, and the thick
+forests, with undergrowths of gigantic ferns, were inhabited by large
+numbers of articulated animals, amongst which were scorpions and
+insects. The scorpions of that time resemble in every way those that
+actually live at the present day in tropical countries; and amongst the
+insects of that early epoch were some very like the cockroaches of
+to-day. Certain tree-like ferns of the present time are also very
+similar to those of the coal period. Amongst the animals the bodies of
+which are protected by a shell, such as foraminifera and mollusca,
+certain species have survived even from an earlier time than the coal
+period.
+
+In contrast with this extraordinary survival, there are instances of the
+complete disappearance of numbers of species of animals and plants. In
+early times, during the Tertiary epoch, the virgin forests of Europe
+were inhabited by a large number of monkeys, of which fossil remains are
+now found, especially in Greece. These formerly existed even in Europe,
+and some anthropoid apes (_Dryopithecus_) have left traces in the
+tertiary deposits of France.[28] These animals, notwithstanding that
+their organisation was superior to that of scorpions and cockroaches,
+have not been able to adapt themselves to the altered conditions of
+modern Europe. A similar fate has come upon some of the higher mammals,
+such as the mammoth and the mastodon.
+
+These facts do not bear testimony to the prevalent idea that there
+exists in nature a law of universal progress tending to the production
+of organisms more and more perfect from the point of view of complexity
+of structure. It is incontestable that forms higher in the scale of life
+have developed only after the appearance of lower forms. But it does not
+follow that development always takes a progressive march. Man is one of
+the later species that have appeared upon the earth, but there are
+others of still more recent date. It is very probable that certain
+species of lice have appeared subsequent to man, particularly the
+clothes-louse (_Pediculus vestimenti_). Amongst the true parasites which
+live only in the human body are some that have acquired their specific
+characters after the appearance of man. Such are certain tape-worms and
+microbes, such as a species of _gonococcus_. It is therefore amongst
+parasites and not to man that we must look for the latest products of
+creation.
+
+In nature, then, there is no blind tendency towards progress. Organisms
+almost innumerable are born every day with variable characters. Those
+amongst them which are adapted to existing circumstances survive and
+produce offspring like themselves, but many do not reach maturity, and,
+living only for a short time, die without leaving issue.
+
+To give the reader a better idea of adaptations and of their importance
+to living creatures, it will, perhaps, be as well to devote some space
+to an account of examples of them. Amongst organisms that attract our
+attention by their pleasing aspect, there are not many that can rival
+flowering plants. Every one admires the great beauty of the blossom of
+orchids. There can be no doubt that these flowers have not been
+developed to satisfy the æsthetic tastes of man, for the simple reason
+that orchids existed for a long time before man’s appearance.
+
+Among orchids there is one which, for more than half a century, has been
+cultivated by man in many tropical countries. This is the Vanilla, the
+fruit of which produces one of the sweetest of spices.
+
+In former days the pods of only the wild vanilla, which is an
+undergrowth of the forests of Mexico and South America, were gathered.
+But the employment of vanilla to flavour chocolate has rendered its
+artificial culture lucrative; consequently the plant has been
+transported to several warm countries where it could be acclimatised. It
+has flourished and borne numerous blossoms, but it has never produced
+fruit from which alone the aroma is obtained. As the question of the
+sterility of the vanilla was of great practical interest to the
+cultivator, the matter was investigated, and it was found that the
+flower remained sterile because the female and male parts could not come
+in contact. The pistils and stamens of the flower are well developed,
+but between these sexual organs is a membrane which prevents
+fertilisation. After this discovery was made, the idea occurred that the
+pollen of the vanilla flower might be transferred artificially to the
+stigma of the pistil so as to bring about “artificial” fertilisation. A
+young black slave, Edmond Albius, a native of Réunion, discovered in
+1841 a practical method by which the male and female elements of the
+vanilla could be put in contact; and from this discovery there came a
+great extension of the cultivation of the orchid in many countries. At a
+certain period a small bamboo point or the tooth of a comb is introduced
+into the vanilla flower, and in this way, in a short time, a quantity of
+flowers may be fertilised and so made capable of bearing mature
+pods.[29]
+
+In the original home of the vanilla the intervention of man is
+unnecessary. In Guiana and Mexico fertilisation of the flower is the
+work of small bees (of the genus _Melipona_). They frequent the vanilla
+flowers to extract nectar, the material of their honey. Small
+humming-birds also hover over the vanilla blossoms, and by introducing
+their bills into the sexual organs of the flowers bring about contact of
+the male and female elements.
+
+Sterility of the vanilla in the countries to which it has been
+introduced, before the employment of artificial fecundation, is easily
+explained by the fact that in these countries there are no insects nor
+humming-birds capable of transporting the pollen.
+
+But it is not only the vanilla that requires the co-operation of living
+beings to produce its fruits. It is the case with many other orchids. In
+the flowers of these the pollen is massed together and cannot be
+transported by the air. It needs the aid of insects, as had already been
+pointed out by Sprengell in the eighteenth century, and above all by
+Darwin, whose splendid investigations are the basis of the following
+passages.[30]
+
+Insects, belonging to different groups, such as bees, wasps, flies,
+certain beetles, and many butterflies and moths, visit orchids to sip
+the nectar produced by the plants and stored in definite parts of the
+flowers. In order that their proboscis may reach the stores of sweet
+juice, the insects inevitably touch first the upper parts of the
+flowers, where the anthers are present. The pollen grains are clustered
+in masses, known as pollinia, and these adhere to the body of the
+visiting insect by means of an adhesive fluid which is secreted by an
+organ of the flower known as the _rostellum_. In this way the pollinia
+adhere firmly, it may be to the proboscis of butterflies, or to the head
+or any other part of the body of insects. They can leave the flower and
+fly away without losing the adhering pollinia, and in this manner they
+serve as the agents for sexual contact and for fertilisation of the
+orchids. Ménière relates that a person who kept bees near the garden of
+the Faculté de Toulouse complained that they returned from the garden
+with their heads covered with tiny yellow bodies which he was unable to
+clean off from them. It was easy to recognise in these bodies the
+pollinia of orchids very firmly attached to the bees’ heads.[31]
+
+When an insect, bearing these pollinia, introduces itself into another
+flower of the same species of orchid, it inevitably comes in contact
+with the female apparatus, more particularly with the viscous surface of
+the stigma. Some of the grains of pollen contained in the pollen-mass
+adhere to the stigma and are thus enabled to fertilise the ovule. This
+carriage of pollen from one flower to another brings about a crossing
+which is necessary for the production of good seed. On the other hand,
+the seed which is the result of self-fertilisation of a flower is
+inferior.
+
+An examination of the structure and form of the flowers of many orchids
+show that they are adapted in a truly marvellous way to the visits of
+insects that convey pollen. In each part of these flowers one can
+discern some useful arrangement to secure cross-fertilisation.
+
+For the proper transmission of pollen it is necessary that the pollinia
+should adhere very firmly to the body of the insects, and that the
+viscous substance which holds them together should have time to
+solidify. It is thus of great advantage to the plant if the insects
+remain for a considerable time on the flower. In several orchids the
+nectar is not easily accessible, and frequently the insect has to search
+for a long time before finding what it desires, and sometimes it even
+has to pierce a membranous covering before reaching the fluid. The
+operation takes a certain time, and this is long enough to allow the
+mucus by which the pollinia adhere to the insect to set firmly.
+
+In the case of orchids the mucus of which sets instantaneously, there is
+no reason for the visit of the insect to be prolonged. In such cases the
+nectar is easy to extract, and the insect finds it without loss of time.
+
+Darwin, after describing these facts, proceeds to say:[32]
+
+“In these five species” (in which the viscid matter “is so adhesive that
+it serves to attach the pollinia firmly to the insects without getting
+hard”), “and in these alone, we find copious nectar ready stored for
+rapid suction in open nectaries. On the other hand, whenever the viscid
+matter gets hard by exposure for a short time to the air, it would
+manifestly be advantageous to the plant if insects were delayed in
+obtaining the nectar; and in all such species the nectar is lodged
+within intercellular spaces, so that it can be obtained only by the
+inner membrane being penetrated at several points, and this will require
+time. If this double relation is accidental, it is a fortunate accident
+for the plants; but I cannot believe it to be so, and it appears to me
+one of the most wonderful cases of adaptation which has ever been
+recorded.”
+
+Some orchids secrete instead of nectar a clear liquid like water. This
+fluid is collected in a petal inserted at the lower part of the flower
+and shaped into a deep cup-shaped receptacle. It does not attract
+insects, but by wetting their wings compels them to leave the flower by
+a different exit which passes close to the reproductive organs (_i.e._,
+the anther and the stigma). The soft linings of the cup are greedily
+devoured by certain insects, particularly by bees. Dr. Cruger, who
+observed this, has often seen bees fall into the cup whereupon their
+wings became so wet as to prevent their flying away, and they have been
+obliged to get out by the channel that carries off the waste from the
+reservoir. As the saturated bees creep along the narrow passage after
+their involuntary immersion, they come inevitably in contact with the
+stigma and the masses of pollen. The latter adhere to the bodies of the
+bees and can be conveyed to the sticky stigma of a neighbouring flower.
+
+[Illustration:
+
+  FIG. 1.—_Catasetum saccatum_ (from “La Lindenia,” Gand, 1890).
+]
+
+In other orchids (_Catasetum_, Fig. 1), the male elements are discharged
+by a spring-like arrangement on the body of insects. When certain parts
+of the flowers are touched, the pollinia are thrown off like arrows,
+which, in the place of the barbs, have viscid swellings. “The insect,
+disturbed by so sharp a blow, or after having eaten its fill, flies
+sooner or later away to a female plant and, whilst standing in the same
+position as before, the pollen-bearing end of the arrow is inserted into
+the stigmatic cavity, and a mass of pollen is left on its viscid
+surface.”[33]
+
+After giving detailed descriptions of the cross-fertilisation of flowers
+by such peculiar means, Darwin makes the following remark: “Who would
+have been bold enough to have surmised that the propagation of a species
+depended on so complex, so apparently artificial, and yet so admirable
+an arrangement?”[34]
+
+One orchid (_Herminium monorchis_, Fig. 2), which bears very small
+flowers, is remarkable for the way in which it is fertilised by insects.
+Only very small insects are able to penetrate the flowers. The space
+being very limited these minute insects can enter the flower only in a
+particular way, and at one of the corners. This causes the pollinia to
+become attached always to the same place, which is on the outer side of
+one of the two front legs. When the insect, the carrier of the pollinia,
+enters a second flower, it can scarcely fail to fertilise the stigma,
+which is on the corresponding side. Darwin said that it would be
+difficult to find a case in which there was so marvellously complete an
+adaptation to a very peculiar mode of fertilisation as the little flower
+of _Herminium_.
+
+[Illustration:
+
+  FIG. 2.—_Herminium monorchis_
+
+  (after Sowerby, “English Botany,” ix. 1869)
+]
+
+In addition to orchids, there are other flowers the organisation of
+which is adapted in a remarkable way to fertilisation by insects. But to
+find perfect harmony in the nature of living beings it is not necessary
+to confine our observations to flowers. The animal world furnishes us
+with numerous examples. To avoid going into the details of these, I
+shall content myself with a description of the most remarkable
+instances.
+
+Every one has seen, flying near the ground, small, slender, and pretty
+wasps. From time to time these bury themselves in the earth or sand, and
+re-appear in a few minutes. These are the fossorial wasps, the
+interesting habits of which have been studied by Mr. J. H. Fabre, of
+Avignon. They are not gregarious, but lead solitary lives and differ in
+their habits from their congeners. Bees feed their larvæ with honey and
+pollen which they take to them during the whole period of their
+development. Wasps are carnivorous, predatory insects, and bring their
+spoils to their brood of soft and feeble larvæ which are unable to
+provide for themselves. Bees and most wasps look after the welfare of
+their young ones in the fashion of human parents in nurseries.
+
+Fossorial wasps act differently; they never see their young. They lay
+their eggs in burrows, sunk in the soil and hermetically sealed. The
+larvæ are hatched underground and are never seen by the mother.
+Provision sufficient for their development, however, is made in advance.
+Before depositing eggs, the females sink the burrows, and fill them with
+the spoils of the chase, which consist sometimes of spiders and
+sometimes of crickets or other insects. Each species of fossorial wasps
+preys on a particular kind of insect or on its allies, for the purpose
+of provisioning the burrows. These wasps are most fastidious in the
+choice of their food, and behave like collectors whose interest is only
+in a single or a few species of small animals. Léon Dufour, the
+well-known entomologist, was much struck by the ability displayed by
+certain wasps (_Cerceris_, Fig. 3) in seeking out and capturing the
+pretty beetles of the genus _Buprestis_, which he had great difficulty
+in finding himself. In making a study of these beetles he collected the
+material from the burrows of _Cerceris_, and so avoided the laborious
+task of obtaining them in the natural state of freedom. The burrows were
+filled with motionless, but perfectly well preserved, _Buprestes_.
+Although dead Coleoptera dried up in a short time, those recovered from
+the burrows remained in a good state of preservation for weeks. Léon
+Dufour came to the conclusion that the _Cerceris_ kill their prey, but
+inject into them some antiseptic liquid which perfectly preserves their
+flesh and intestines.
+
+[Illustration:
+
+  FIG. 3.—_Cerceris_ (after Buffon).
+]
+
+J. H. Fabre pursued the study of the habits of fossorial wasps further.
+He ascertained that the captured insects were not dead, but only
+paralysed. The continuance of the function of certain organs
+demonstrated that the _Buprestes_, the weevils and other small creatures
+collected in the burrows of fossorial wasps, were alive. They could even
+perform some slight movements, but they were incapable of locomotion,
+and so could not escape. The mechanism of this paralysis, as far as
+could be ascertained by Fabre, is one of the most remarkable phenomena
+in nature. The fossorial wasps, guided by their instinct, immediately
+after having seized an insect or spider, bury their sting in the nervous
+centre which controls the movements of the legs. When animals with soft
+bodies, such as spiders and young crickets, are attacked, the operation
+does not present any difficulties. But Coleoptera in general, and the
+_Buprestes_ and weevils in particular, are furnished with a very hard
+covering which cannot be perforated by the small and slender sting of a
+fossorial wasp. To gain their object the wasps probe exactly between the
+first and second pair of legs in the median line of the under surface of
+the thorax. The skin is thinner at this spot, and they introduce their
+sting into the ganglia from which arise the nerves of the legs. In the
+case with the _Buprestes_ these ganglia are set close to one another,
+and a single prick suffices to affect the nervous centres of three pairs
+of legs. Once the sting has been inserted in this way the _Buprestis_
+becomes paralysed, but lives for many days. “The _Cerceris_ which preys
+on Coleoptera,” writes Fabre,[35] “appears to have made its choice
+according to the dictates of an exact physiology and anatomy. It is
+impossible to see in its proceedings the results of happy chance; more
+than chance is required to explain adaptations so precise.”
+
+After having filled the burrow with a sufficient quantity of insects or
+spiders, fossorial wasps lay their eggs and carefully close up the
+entrance. In due course the larva is hatched, and devours the food that
+it finds close at hand. If the gathered insects were not paralysed, they
+could easily escape from their prison; if they were dead, putrefaction
+or desiccation (according to circumstances) would render them unfit for
+the larvæ. It is therefore sheer necessity that is the factor in the
+development of this marvellous instinct that induces the fossorial wasps
+to attack the nervous centres of their prey. When one insect has been
+devoured, the larva proceeds to another, and so on, until it is fully
+grown, whereupon it envelops itself in a case that protects it during
+the winter and following spring. In summer it changes at first into a
+chrysalis, and later into a perfect insect. It frees itself from the
+cocoon, takes to flight, and enters upon life like that of its mother,
+which it has never seen.
+
+Of the harmonious phenomena in nature it is indeed difficult to find
+other examples so perfect as those of the habits of these fossorial
+wasps, or of the mechanism for the fertilisation of orchids. These
+harmonies in nature are constantly met with in the world of living
+beings, and it is not astonishing that they have for a long time
+attracted the attention of many observers and philosophers. As it seemed
+impossible to attribute them to the organisms themselves, because of the
+low rank and lack of intelligence of these, it has seemed only natural
+to set them down as a manifestation of a superior force which organises
+and directs all natural phenomena. This argument, however, omits one
+side of the medal.
+
+Any close investigation of organisation and life reveals that, beside
+many most perfect harmonies, there are facts which prove the existence
+of incomplete harmony or even absolute disharmony. The examination of
+the flowers of orchids would lead one to the belief that each part, even
+the smallest and apparently most insignificant, has its _rôle_ in the
+mechanism for fertilisation and cross-fertilisation. In reality it is
+not so. There are in certain orchids organs which do not fulfil any
+function.
+
+Even among the species of _Catasetum_, in which the pollinia are thrown
+with force on the bodies of insects, there are some female flowers in
+which the male organs are rudimentary and without utility. In these
+flowers, according to Darwin,[36] “the two membranous sacks containing
+the rudimentary pollen-masses never open, but they easily separate from
+each other and from the anther. The tissue of which they are formed is
+thick and pulpy. Like most rudimentary parts, the pollen-masses vary
+much in size and form; they are only about one-tenth of the bulk of
+those of the male.” There are then, without doubt, some structures that
+are of no service.
+
+The existence of these rudimentary pollinia, incapable of being
+transported or of fertilising the female element, is easily explained by
+the supposition that formerly the flowers of the _Catasetum_ were true
+hermaphrodites, but that in the course of time the male organs have
+become incompletely atrophied in certain flowers, in which, on the other
+hand, the female part has increased. The occurrence of an actual
+degeneration is shown by the existence of rudiments of the pollinia too
+insignificant to accomplish their normal functions.
+
+Rudimentary and useless organs are widely distributed, and we find them
+in many places. Familiar instances are the atrophied eyes of animals
+that live in the dark, and the sometimes rudimentary sexual organs of
+many plants and animals.
+
+Not only are orchids and other flowers adapted to fertilisation by means
+of insects, but many insects display special adaptations to their habit
+of visiting flowers. Butterflies, bees, and many other insects, possess
+mouth organs modified for the purpose of penetrating flowers to secure
+nectar or pollen. Other insects, again, are not so fortunate in this
+respect. Darwin[37] on one occasion “found an extremely minute
+Hymenopterous insect vainly struggling to escape, with its head cemented
+by the hardened viscid matter to the crest of the rostellum and to the
+tips of the pollinia (of an orchid, _Listera ovata_, Fig. 4). The insect
+was not so large as one of the pollinia, and after causing the explosion
+had not strength enough to remove them; it was punished for attempting a
+work beyond its strength, and perished miserably.”
+
+[Illustration:
+
+  FIG. 4.—_Listera ovata_ (after Barla, “Flora of Nice,” 1868).
+]
+
+Many insects, well adapted for the purpose, delight themselves by
+sucking the nectar of flowers. Many others would wish to do the same,
+but their want of adaptation baffles them. A small “lady-bird” loves the
+sweet juice of flowers; it tries often to suck the nectar of the
+dandelion, but without success. Hermann Müller[38] has described the
+behaviour of this insect in procuring the nectar of _Erodium
+cicutorium_. “The awkward way in which this beetle, unadapted to feed on
+the plants, endeavours to obtain the honey, is too ludicrous not to be
+mentioned. After taking up a position on the petal, it puts its mouth in
+the direction of one of the honeycups which are situated on both sides
+of the base of the petal. The petal soon breaks off, upon which the
+insect fixes itself on a neighbouring sepal or falls to the ground with
+the petal. In the first case it proceeds to creep over the flower and
+ends by detaching all the petals; in the other case, on recovering from
+the shock, it quickly ascends another stem of the same plant and begins
+again. I have seen the same lady-bird fall four times in succession with
+petals which it had detached without gaining wisdom.”
+
+The instincts of insects, well developed for certain functions, often
+present aberrations more or less whimsical and remarkable. The
+caterpillars of some butterflies, before changing into chrysalids,
+envelop themselves in a wellwoven cocoon capable of protecting them from
+noxious influences. Protected by this covering, the caterpillar changes
+into a chrysalid, and later into a butterfly, which perforates the end
+of the cocoon in order to emerge. When any external agency destroys the
+cocoon, normal metamorphosis becomes impossible, and the larva dies
+before its maturity. Fabre[39] questioned whether the caterpillar during
+the time of the weaving of the cocoon was capable of repairing it if it
+was damaged. For this object he cut with a pair of scissors the end of a
+cocoon in the course of construction by the caterpillar of the beautiful
+peacock-butterfly. In spite of the hole thus produced, the caterpillar
+continued its ordinary work without suspicion that it would be of no
+avail. On this occasion “the caterpillar of the peacock-butterfly,
+notwithstanding the certain fate of the future butterfly, continued
+peaceably to spin, without in the least modifying the regular progress
+of its labour; when the time had arrived for the putting in of the last
+defensive stitches it placed them in the perilous breach, but neglected
+to mend the destroyed part of the barricade. It performed its vain task,
+ignoring what was indispensable for success.”
+
+Even amongst fossorial wasps, the instincts of which are so admirably
+developed, harmony is far from perfect. Fabre endeavoured to ascertain
+what effect was produced on these insects by taking away the egg laid in
+the burrow. He chose for this experiment the fossorial wasp _Pelopæus_
+(Fig. 5), which preys on spiders. He took away the egg which had been
+deposited in a carefully-prepared burrow, and watched the subsequent
+manœuvres. “The _Pelopæus_ continued to store up spiders for the stolen
+egg; it gathered provisions that were not to be eaten; it redoubled its
+efforts to replenish a larder that I was constantly robbing with my
+forceps.” The insect neither discontinued its fruitless task nor
+appeared to be aware of its fruitlessness. Here, then, is an example of
+a foiled maternal instinct that gained no useful end.
+
+[Illustration:
+
+  FIG. 5.—_Pelopæus_ (after Buffon).
+]
+
+In connection with such a slaughter for the benefit of a progeny that
+will never exist, I may mention observations relating to a quite
+different order of phenomena. There are many creatures that kill and
+devour their progeny. Not infrequently rabbits kill and devour all their
+progeny, or leave them to die without food or care. Sometimes the
+culprits are young rabbits without experience; but this aberration of
+instinct is also met with in old rabbits, which once and for all have
+contracted the habit of abandoning or eating their young. Some females
+of other species of mammals and of birds have often been surprised in
+the act of deserting or of killing their offspring.
+
+Perversion of sexual instinct is frequent enough amongst animals.
+Huber[40] states that when male ants have a lack of females they ravish
+the workers, the attacks being fatal, as the sexual organs are
+incompletely developed and functionally incapable. Abnormal pairing has
+also been observed in the stag-beetle of the genus _Lucanus_, in bees,
+and, above all, in cockchafers.[41] Higher animals, such as dogs,
+furnish analogous examples of sexual perversion.
+
+Onanism is well known amongst mammals. It is frequent among monkeys in
+menageries, and also in rutting stags, the latter discharging the
+seminal fluid by friction with trees. Stallions and mares have often
+been observed in the act of satisfying their sexual appetites by
+abnormal means. There are several other species (dogs, bears, chamois,
+elephants, parrakeets, etc.,) which resort to onanism.[42]
+
+These disharmonious instincts do not in the least cause the death of the
+animals that manifest them. But there exist in nature instinctive
+aberrations much more dangerous. Who has not seen in the summer numerous
+insects gathered round lamps and candles, attracted by the light? Among
+these are Coleoptera, Neuroptera (_Phryganea_), Ephemera, and, most
+frequently of all, small nocturnal Lepidoptera. After flying round and
+round the light several times, they singe their wings and die in
+numbers. This instinct is so constant and so developed amongst many of
+these insects, that it has been used against them for their own
+destruction. Thus amongst the means advocated for destroying a moth,
+_Botys sticticalis_, the caterpillars of which devour cereals and
+beetroot,[43] is the lighting of numerous fires in the fields. The
+moths, attracted by the light, fall in the flames and die in quantities.
+
+When the usual swarms of may-flies emerge from the water, fishers make
+straw fires on their boats, and the insects singe their wings. The
+innumerable bodies incapable of flight fall into the water, and provide
+a coveted food for the fish.[44] This disharmonious and fatal instinct
+is displayed chiefly by nocturnal insects that rest during the day and
+do not leave their retreats till after sunset. In the cornfields
+Coleoptera of the genera _Anisoplia_ and _Rhizotrogus_, resembling each
+other in form and general appearance, are to be found. When a fire is
+lighted in the darkness of the night it is only the _Rhizotrogus_ that
+approaches it at the risk of its life. The _Anisoplia_ remains quiet in
+the midst of the corn. The latter kind of beetle pairs during the day,
+while the _Rhizotrogi_ satisfy their sexual desires during the night.
+Moreover, it is the males only of this species that fly about in the
+darkness and approach the fire, whilst the females rest at home in the
+plants.[45] It is probable, therefore, that light induces a sort of
+sexual excitement in these male beetles. The males, searching for the
+female, believe her to be in the midst of the flames, towards which they
+fly without being conscious of the danger they incur.
+
+Such an interpretation of this disharmonious and suicidal instinct is
+confirmed by the fact that the moths attracted by fire are also almost
+exclusively males. Moreover, entomologists have advised against the
+lighting of fires by agriculturists in the belief that they destroy the
+noxious _Botys_, as they maintain that the females are not attracted.
+These latter therefore live on, and, being capable of laying eggs,
+produce a generation of voracious caterpillars.
+
+Of the _Ephemera_ attracted by fire in such great quantities males are
+by far the more numerous. It is therefore really very probable that the
+mad excitement which leads to the destruction of so many male insects,
+represents a sort of sexual aberration. In this connection it is to be
+remembered that, amongst Coleoptera, species exist of which the females,
+hidden in the grass, produce intense light which attracts the males. In
+the common glow-worm, the female, which is devoid of wings, alone shines
+with the familiar greenish glitter. Even in species of which the two
+sexes are luminous, the female shines more vividly. It is true that
+there are some beetles with luminous larvæ, a fact that led Darwin[46]
+to remark that the production of light by insects may serve to frighten
+enemies. This is possible, and it is also possible that certain insects
+make use of their luminosity to light their way in the darkness.[47]
+But, notwithstanding this, the sexual character of the luminous organ is
+so manifest in certain species that it is impossible to doubt its
+function as a means of attracting the male.
+
+In conclusion I may say that it is not my purpose at present to discuss
+the meaning of an instinct so fatal to insect life. I wish only to point
+out the frequency of the natural occurrence of disharmony, so that the
+satisfaction of an instinct is fatal to so many of its possessors.
+
+It is plain that an instinct, or any other form of disharmony leading to
+destruction, cannot increase, or even endure very long. The perversion
+of the maternal instinct tending to abandonment of the young is
+destructive to the stock. In consequence, individuals affected by it do
+not have the opportunity of transmitting the perversion. If all rabbits,
+or a majority of them, left their young to die through neglect, it is
+evident that the species would soon die out. On the contrary, mothers,
+guided by their instinct to nourish and foster their offspring, will
+produce a vigorous generation capable of transmitting the healthy
+maternal instinct so essential for the preservation of the species. For
+such a reason harmonious characters are more abundant in nature than
+injurious peculiarities. The latter, because they are injurious to the
+individual and to the species, cannot perpetuate themselves
+indefinitely.
+
+In this way there comes about a constant selection of characters. The
+useful qualities are handed down and preserved, while noxious characters
+perish and so disappear. Although disharmonies tend to the destruction
+of a species, they may themselves disappear without having destroyed the
+race in which they occur.
+
+This continuous process of natural selection, which offers so good an
+explanation of the transmutation and origin of species by means of
+preservation of useful and destruction of harmful characters, was
+discovered by Darwin and Wallace, and was established by the splendid
+researches of the former of these.
+
+Long before the appearance of man on the face of the earth, there were
+some happy beings well adapted to their environment, and some unhappy
+creatures that followed disharmonious instincts so as to imperil or to
+destroy their lives. Were such creatures capable of reflection and
+communication, plainly the fortunate among them, such as orchids and
+fossorial wasps, would be on the side of the optimists; they would
+declare this the best of all possible worlds, and insist that, to secure
+happiness it is necessary only to follow natural instincts. On the other
+hand, the disharmonious creatures, those ill adapted to the conditions
+of life, would be pessimistic philosophers. Consider the case of the
+lady-bird, driven by hunger and with a preference for honey, which
+searches for it on flowers and meets only with failure, or of insects
+driven by their instincts into the flames, only to lose their wings and
+their lives; such creatures, plainly, would express as their idea of the
+world that it was fashioned abominably, and that existence was a
+mistake.
+
+As for man, the creature most interesting to us, in what category does
+he fall? Is he a being whose nature is in harmony with the conditions in
+which he has to live, or is he out of harmony with his environment? A
+critical examination is needed to answer these questions, and to such an
+examination the pages to follow are devoted.

+
+
+To understand human nature it is necessary first to give an account of
+the origin of man. This question has preoccupied mankind for ages, and
+for a long time it was believed that a solution of the problem was to be
+found in religious dogmas. Man was regarded as being of supernatural
+origin, the result of a special creation. Scientific criticism has now
+shown that there are no grounds for such a conclusion.
+
+Nearly half a century ago Darwin applied to man his discovery of the
+principle of natural selection, and of the part played by that in the
+origin and transmutation of species. Soon after the publication of the
+“Origin of Species,” attention was given to the special case of man. In
+1863 Huxley[48] gave an admirable review of the problem in his work on
+“Man’s Place in Nature.” He brought forward arguments of the highest
+scientific validity in support of the thesis that man is descended from
+animals, and that he is a mammal most nearly related to monkeys, and
+among these to the anthropoid apes. In spite of this masterly
+exposition, there are still persons of high intelligence and superior
+education who declare that science has not yet answered the question as
+to whence he came, and that the theory of evolution will never provide
+an answer.[49] Close examination of the structure of man has proved, in
+the most definite fashion, the existence of a near kinship with the
+higher monkeys, or anthropoids. When the chimpanzee and the
+ourang-outang were discovered, comparison became inevitable, and many
+naturalists, including the great Linnæus, saw that the human race must
+find its place in classification near the anthropoids.
+
+Now that all the details of the human organisation have been studied,
+and the anatomical structures of man and large monkeys without tails
+have been compared, bone with bone and muscle with muscle, a truly
+astonishing analogy between these organisms is made manifest, an analogy
+apparent in every detail. It is known that in the natural history of
+mammals the teeth play an important part as a means of determining
+differences and relationships. The dentition of man bears a very great
+resemblance to that of anthropoids. Every one knows the _milk teeth_ and
+the _permanent teeth_ of man. The anthropoid apes bear in this respect
+an astonishing likeness to man. The number (thirty-two in the adult),
+the form and general arrangement of the crown, are identical in man and
+anthropoid apes. The differences are to be found only in minor details,
+such as the exact shape and relative dimensions and the number of cusps.
+It can be said in a general way that in the anthropoid apes the teeth
+are more strongly developed than in man. The canines are much longer and
+the roots of the pre-molars are more complex in the gorilla than in man.
+
+But the fact must not be lost sight of, that all these differences are
+less pronounced than those which exist between the dentition of
+anthropoid apes and that of all other monkeys. Even in the cynocephalous
+monkeys, those that most nearly approach the anthropoids, the teeth
+exhibit marked differences. Thus, the forms of the upper molars are
+quite different in the baboon and in the gorilla. The canines are
+longer, and the pre-molars and molars are still more complex in the
+baboon.
+
+In the monkeys of the New World, the dentition differs still more from
+that of man and anthropoids. Instead of thirty-two teeth, they possess
+thirty-six in the adult condition. The number of pre-molars is twelve
+instead of eight. The general form and the crowns of the molars are very
+different from those of anthropoid apes.
+
+These considerations led Huxley to conclude that “it is obvious that,
+greatly as the dentition of the highest ape differs from that of man, it
+differs far more widely from that of the lower and lowest apes.”[50]
+
+Another character which shows that anthropoids are nearer man than other
+monkeys is furnished by the anatomy of the sacrum. In monkeys as a whole
+the sacrum is composed of three, or rarely four, vertebræ, while in
+anthropoid apes it contains five, that is to say just as many as in man.
+
+The whole skeleton, and particularly the skull of man, and the higher
+monkeys, present certainly some marked differences; but here again the
+differences are less than those between the anthropoid apes and other
+monkeys. As regards the osteology the proposition laid down by Huxley is
+just. “So that, for the skull, no less than for the skeleton in general,
+the proposition holds good, that the differences between man and the
+gorilla are of smaller value than those between the gorilla and some
+other apes.”[51]
+
+The believers in the doctrine that the human species is essentially
+distinct from all the known monkeys have laid great stress on the
+difference between the foot of man and that of anthropoid apes. This
+difference cannot be denied. Man assumes the direct posture habitually,
+while monkeys, even the highest of them, walk on two legs only
+occasionally. There has followed from this a greater development of the
+feet in monkeys. Yet this difference ought not to be exaggerated. It has
+been sought to prove that monkeys are “quadrumanous,” and that their
+hind legs terminate in “hind-hands.” But it is clearly shown that in all
+essential respects the hinder limb of the gorilla terminates in as true
+a foot as that of man.[52] “The hind limb of the gorilla, therefore,
+ends in a true foot, with a very movable great toe. It is a prehensile
+foot, indeed, but is in no sense a hand; it is a foot which differs from
+that of man not in any fundamental character, but in mere proportions,
+in the degree of mobility, and in the secondary arrangement of its
+parts.”[53]
+
+In all these cases the argument is confirmed, “that be the differences
+between the hand and foot of man and those of the gorilla what they may,
+the differences between those of the gorilla and those of the lower apes
+are much greater.”[54]
+
+The comparison of muscles and of other internal organs leads to the same
+conclusion; the differences between monkeys are more varied and greater
+than those between anthropoids and man. The anatomy of the brain has
+been much discussed with regard to this. Several distinguished
+zoologists, amongst them Owen in particular, have insisted on the
+absence in all monkeys of certain parts of the brain peculiarly
+characteristic of man. Such are the posterior lobe, the posterior cornu,
+and the lesser hippocampus. Controversy on this topic has been animated;
+but, ultimately, the opinion of Owen did not triumph, and now it is
+unanimously accepted that the parts of the brain in question are
+“precisely those structures which are the most marked cerebral
+characters common to man with the apes. They are among the most
+distinctly simian peculiarities which the human organism exhibits.”[55]
+
+[Illustration:
+
+  FIG. 6.—Cæcum and vermiform appendage of man (after Ewald).
+]
+
+As regards the brain, the differences between man and anthropoid apes
+are certainly less marked than those that exist between the higher and
+lower monkeys.
+
+The digestive tract affords another argument in favour of the affinity
+of anthropoid apes to man. The human cæcum is furnished with the very
+remarkable and strange vermiform appendage which often is the cause of a
+grave and prevalent illness known as _appendicitis_. Now, it is quite
+remarkable that this organ is practically identical with the vermiform
+appendage of anthropoid apes. A glance at the accompanying figures (6
+and 7) will convince the reader of this. Yet none of the other monkeys
+present any such resemblance with man.
+
+[Illustration:
+
+  FIG. 7.—Cæcum and vermiform appendage of the chimpanzee (from a
+    preparation in the Paris Museum of Natural History).
+]
+
+It is not surprising, in the face of resemblances so numerous, that
+forty years’ science has proclaimed the existence of a close affinity
+between man and the anthropoid apes. The view has become an established
+doctrine, now that no single fact has been brought against it. Since the
+theory was enunciated we have learned much regarding the natural history
+of these apes. Generally, when a theory is false, a new set of facts
+overthrows it. Attempts may be made to trim the new facts to the
+existing theory, but such attempts are doomed to failure, and the theory
+disappears. It is of special interest, then, to confront the simian
+theory of the origin of man with a series of facts gathered by science
+since the theory was propounded.
+
+When Huxley wrote, the embryological history of anthropoid apes was
+practically unknown. Darwin, Vogt, and Haeckel, in their attempts to
+support the theory of the animal origin of man, had not sufficient
+knowledge of the embryology of monkeys. It is only recently that
+important work on this subject has been published.
+
+It is known that the history of development is very often an excellent
+guide in tracing the relationship of organisms. It is therefore
+interesting to examine the established facts concerning the embryology
+of anthropoid apes. The material for these studies is very difficult to
+obtain, and it is not astonishing that even our present state of
+knowledge is still imperfect.
+
+[Illustration:
+
+  FIG. 8.—Fœtus of gibbon (after Selenka).
+]
+
+The placenta often gives information of great importance in the
+classification of mammals. It is sufficient to glance at the zonary
+placenta of dogs and seals to be convinced of the relationship of these
+two species, which at first sight seem so different. Now, the placentas
+of all the anthropoid apes examined up to the present are of the same
+discoid type as that of man. The arrangement of the umbilical cord of
+man, which was formerly considered as quite peculiar to him, is found in
+anthropoid apes, as has been established by Deniker[56] and Selenka[57]
+It is striking that the anthropoids resemble man rather than the lower
+monkeys in the relation of the fœtus to the fœtal membranes.
+
+[Illustration:
+
+  FIG. 9.—Human fœtus of three months and a half.
+]
+
+With regard to the embryos themselves, the similarity between those of
+monkeys and of man is very great. Selenka insists on the fact that the
+youngest stages of human development that have been obtained can hardly
+be distinguished from those of the lower monkeys either in position or
+in shape. More advanced stages exhibit greater differentiation, and the
+later embryos of man resemble those of anthropoids much more closely
+than those of the lower monkeys. The fœtus of the gibbon, figured by
+Selenka (Fig. 8), presents the most striking likeness to a corresponding
+human fœtus (Fig. 9).
+
+Later on, the characters that distinguish man from even the highest of
+the apes become more and more pronounced. In the anthropoids the facial
+portion becomes more and more prominent, and betrays a bestiality absent
+from the human form. None the less the resemblance between the nearly
+mature fœtus of anthropoids and human embryos of about the sixth month
+is evident enough. M. Deniker had the good fortune to obtain the late
+fœtus of a gorilla—a very rare piece of fortune—and he has made an
+elaborate investigation of its structure. The general appearance (Fig.
+10) is quite enough to show the close relationship with a human fœtus of
+a corresponding age (Fig. 11). It is plain, moreover, that the young
+gorilla is more human-like than is the adult. Detailed anatomical
+investigation only confirms this conclusion.
+
+The skulls of the young stages of anthropoids are much more human in
+their character than the adult skulls. Selenka states that such young
+skulls of different anthropoids not only resemble one another more
+closely, but are more human. As soon as the teeth begin to appear, the
+individual characters are assumed so rapidly, and become so marked,
+that, in the absence of the intermediate stages, it would be difficult
+to establish the kinships.
+
+The data derived from embryology do not point to any one of the existing
+genera of monkeys as the ancestor of man. They lead us to infer, rather,
+that man and the anthropoid apes had a common origin, and
+palæontological evidence must be scanned to find this ancestor. The
+greatest importance has been attached to a discovery in Java, made in
+1894 by Eugène Dubois. The remains, consisting of the crown of a skull,
+two teeth and a femur, belonging to a creature for which the name
+_Pithecanthropus erectus_[58] has been invented, have been interpreted
+by several anatomists as those of a form intermediate between man and
+the anthropoid apes. However, as the facts about this creature are
+meagre and have been interpreted differently, I shall not make use of
+them in my argument. Even apart from them, the simian origin of man may
+be taken as proved.
+
+The series of facts that I have been employing as evidence of the
+relationship between men and anthropoid apes has been drawn from the
+observations of anatomists and embryologists. Darwin, seeking to broaden
+the basis of the argument, called attention to the resemblances of the
+parasites of men and apes, as evidence of a close similarity of
+physiological processes in the creatures. In the last few years,
+investigations in a very different field seem capable of throwing a
+novel light on the question.
+
+When the blood of one mammal is injected into the body of another, the
+latter shows remarkable modifications. When there is added to a serum,
+prepared from the blood of a rabbit and consisting of a colourless
+transparent liquid, a few drops of blood drawn from another rodent (for
+instance a guinea-pig), nothing unusual happens. The blood of the
+guinea-pig preserves its normal colour, and its corpuscles remain
+practically unaltered. If, instead of adding guinea-pig’s blood to the
+serum of rabbit’s blood, we add a serum drawn from the blood of the
+guinea-pig, still no special change occurs.
+
+[Illustration:
+
+  FIG. 10.—Fœtus of gorilla (after Deniker).
+]
+
+If, however, a serum be prepared from the blood of a rabbit into which
+there had first been injected the blood of a guinea-pig, the serum shows
+new and striking qualities. The addition to it of some drops of
+guinea-pig’s blood brings about, in a very short time, a changed
+appearance. The red liquid, at first opaque, becomes transparent. The
+mixture of the prepared serum of the rabbit with the blood of the
+guinea-pig will assume the colour of claret mixed with water. The change
+is due to solution of the red corpuscles of the guinea-pig in the blood
+serum of the rabbit.
+
+[Illustration:
+
+  FIG. 11.—Human fœtus of about five months.
+]
+
+This serum has still another property not less worthy of attention. If
+there is added to it not pure blood but only blood serum of the
+guinea-pig, a disturbance in the mixture occurs almost at once, and
+leads to the forming of a precipitate more or less abundant.
+
+The injection of the blood of the guinea-pig into a rabbit has therefore
+changed the serum of the latter by introducing new properties: that of
+dissolving the red corpuscles of the guinea-pig and of giving a
+precipitate with the blood serum of the same animal.
+
+Frequently the blood serum of animals prepared by previous injections of
+the blood of other species of animals is strictly specific. In such
+cases the serum only gives a precipitate with the serum of the species
+which has furnished the blood for the injections, and only dissolves the
+red corpuscles of this same species. But there are some instances in
+which a serum of a prepared animal dissolves, not only the red
+corpuscles of the species which has furnished the injected blood, but
+those of allied species. Thus the blood serum of the rabbit, after some
+injections of blood of the chicken, becomes capable of dissolving not
+only the red corpuscles of the chicken but also those of the pigeon,
+although in a less degree.
+
+It has been suggested that assistance could be rendered to forensic
+medicine by making use of this property of serums, to discover the
+origin of a certain blood. As is well known, it is often very important
+to decide whether a stain was caused by the blood of man or of another
+animal. Until quite recently it was not known how to distinguish human
+blood from that of other mammals. Experiments have been made to discover
+if the red corpuscles found in the blood stain could be dissolved by the
+serum of animals which had previously been injected with the blood of
+man. In a certain case the human origin of the stain in question was
+shown. But it was soon discovered that this method was not infallible.
+It is now found that the method of precipitates gives much more
+conclusive results. It is done in this way: Human blood is injected
+several times into any animal (rabbit, dog, sheep, horse). Some time
+afterwards the animal is bled, and a clear and limpid serum, quite
+devoid of corpuscles, is prepared. When there is added to this serum one
+or several drops of human serum, it forms immediately a precipitate
+which falls to the bottom. In this way it is discovered whether the
+prepared serum is sufficiently active. It then becomes possible to
+recognise even dried human blood. A little of such blood is dissolved in
+normal salt solution, and placed in a tube containing the serum of an
+animal prepared by means of the injections of human blood. If a
+precipitate forms in the liquid in a short time, the fact indicates that
+the stain is really human blood. This method is being practised in
+forensic medicine.
+
+This reaction is of great interest to us because it is of assistance in
+revealing the relationship between species. The serum of an animal
+prepared with the blood of the fowl gives a precipitate, not only with
+the serum of the fowl itself, but also with that of the pigeon; on the
+other hand, it remains undisturbed when the serum of mammals is added.
+The reaction indicates then that there is a sufficiently marked degree
+of relationship between the fowl and the pigeon. Here is another
+example: the serum of an animal prepared with the blood of an ox gives
+an abundant precipitate when there is added to it a little blood serum
+of the ox, but it does not produce this reaction with the serum of any
+of the other mammals, not even with that of the sheep, stag and
+deer.[59] The relationship between the _Bovidæ_ and these other
+ruminants is then not so close as that between the fowl and the pigeon.
+
+How does the serum of animals which has been injected with human blood
+behave? The serum capable of giving a precipitate with human serum does
+not produce the same reaction except with the serum of some monkeys (the
+small _Papio_).[60]
+
+Gruenbaum, of Liverpool,[61] has been fortunate enough to procure a
+considerable quantity of the blood of three large anthropoid apes—the
+gorilla, chimpanzee, and ourang-outang. He has been able to prove that
+the serum of animals injected with man’s blood gives a precipitate not
+only with this blood but also with that of the above-mentioned apes. It
+was impossible for him “to distinguish this precipitate as regards
+quality and quantity from that which is obtained with human blood.”
+
+To verify this result, Gruenbaum prepared the serum of animals injected
+with the blood of the gorilla, chimpanzee, and ourang-outang. These
+three kinds of serum gave precipitates with the blood of these three
+apes, and to the same extent with the blood of man. It is therefore
+evident that there exists between the human species and the anthropoid
+apes not only a superficial analogy of body and of the principal organs,
+but a close blood relationship.
+
+Facts of this kind could not be foreseen when the theory of the simian
+origin of man was put forward. In spite of this they have arisen to
+confirm it in a truly astonishing way.
+
+It is therefore impossible to doubt that man is a member of the group of
+primates having a close connection with the higher monkeys of the
+present time. This result is of great importance in all questions
+relating to human nature.
+
+It would certainly be of considerable interest to know more exactly what
+steps were followed in this simian descent of man. On this question our
+knowledge is still very imperfect. In his researches on anthropoid apes,
+Selenka insists on a more intimate relationship between the chimpanzee
+and man. “The great resemblance of the pre-molars and of the molars in
+the permanent dentition of the chimpanzee with human teeth appears to
+indicate that the chimpanzee and man have a common origin, and descend
+from extinct forms like _Dryopithecus_. This conclusion, however, is
+contradicted by the fact that the milk teeth of the chimpanzee are much
+nearer those of the ourang-outang than those of man.”[62]
+
+It is evident that to clear up this question it would be necessary to
+have a greater knowledge of fossil anthropoids such as _Dryopithecus_
+and its allies. In the present state of knowledge only a very general
+hypothesis can be formulated as to the exact mode of human descent.
+
+We have already shown that the fœtus of man and of the anthropoid
+monkeys resemble each other much more than the adult forms, and that the
+young of these apes also bear a greater likeness to man than do the
+adults. The great development of the skull as compared with the face is
+characteristic of young monkeys and of man young or old. The jaws
+continue to develop in the anthropoids, while in man there occurs in
+this respect a certain arrest of development. The hairs, so small in
+man, also show a similar arrest. Generally they remain during the whole
+life in a state of incomplete development. It is especially on the back
+of man that this feeble development of hairs occurs. As this part of the
+body in monkeys, on the contrary, is much more hairy than the under
+surface, it has been held to constitute an essential difference between
+man and monkeys. But embryological study enables us to settle this
+apparent contradiction. The fœtus of the gorilla examined by M. Deniker
+possessed an almost entirely smooth back. “The fœtus had true hairs only
+on the head, the anterior surface, and around the lips and the genital
+organs, and the eyelashes and eyebrows. The remainder of the body was
+smooth or covered with down not exceeding a millimetre in length.”[63]
+
+The skin of the under surface, smooth around the navel, was covered with
+small hairs more thickly than on the back. The abundance of hairs on the
+posterior aspect of the body of monkeys is a later acquisition, which
+develops but tardily during fœtal life.
+
+As regards the distribution of these hairs man resembles much more the
+embryos of monkeys than adult monkeys. This fact, instead of shaking the
+theory of relationship between man and apes, gives us strong evidence as
+to the mode of his descent. Putting the known facts together, we may
+infer that man is a case of the arrested development of some simian of
+ancient days, as it were, a simian monster from the zoological point of
+view, although not from the æsthetic. Man may be regarded as a prodigy
+sprung from an ape, born with a larger brain and an intelligence more
+highly developed than occurred in his parents. Such a view is in
+accordance with known facts.
+
+It must be admitted that certain kinds of organisms, instead of evolving
+at a very slow pace, spring up suddenly, and that in such a case nature
+proceeds with a considerable stride. Darwin foresaw this possibility,
+but it has been made plain to us by the remarkable researches of the
+botanist Hugo de Vries.[64]
+
+De Vries cultivated for fifteen years the Evening Primrose, a plant of
+American origin (_Œnothera lamarckiana_). He obtained, suddenly, a set
+of flowers quite distinct from those of the original plant. They
+presented such great differences that he could separate them as several
+quite distinct species. During the first few years De Vries obtained
+three species (_Œnotera lata_, _Œn. nanella_, and sometimes _Œn.
+scintillans_), but variation becoming more and more prevalent, he
+ultimately distinguished a dozen new species. These were grown from
+seed, and transmitted their specific characters to their descendants. De
+Vries, in this way, was a witness of the sudden appearance of new
+species.
+
+It is probable that man owes his origin to a similar phenomenon. Some
+anthropoid ape having at a certain period become varied in specific
+characters, produced offspring endowed with new properties. The brain,
+of abnormal size, placed in a spacious cranium, allowed a rapid
+development of intellectual faculties much more advanced than those of
+the parent and those of the original species. This peculiarity would be
+transmitted to the descendants, and, as it was of very considerable
+advantage in the struggle for existence, the new race would hold its
+own, propagate and prevail. The extraordinary development of
+intelligence necessarily led to perfections in the choice of
+nourishment, perfections which approached the art of preparing more
+digestible food. The jaws, under these conditions, had not such a
+difficult task as before, and, moreover, they were no longer required
+for attack or defence. They became less developed than in the true
+anthropoid apes.
+
+These suggestions involve a conception of the mind that is in harmony
+with known facts. From time to time prodigies are born with some talent
+far greater than the gifts possessed by the parents.
+
+About twelve years ago a young native of Piedmont, Jacques Inaudi by
+name, became famous in Paris on account of his extraordinary power of
+calculation. He had an astonishing memory for figures, and could perform
+mathematical calculations with surprising rapidity.[65] Two minutes were
+sufficient for him to multiply two numbers composed of seven and six
+figures. Other arithmetical calculations, such as the extraction of
+roots, gave him but little trouble.
+
+To attain this result, Inaudi made use of his extraordinary memory for
+figures, founded on the persistence of auditory images. When he heard
+the numbers pronounced, he remembered them. Inaudi declared to the
+Commission convened by the Academy of Sciences, that when he tried to
+recall the numbers he heard them as if repeated aloud, in the tone of
+his own voice, and that he could hear them for the greater part of the
+day. “In an hour, or in two hours’ time, if I thought of the number that
+was uttered, I should be able to repeat it as exactly as I have done
+before the Commission.”
+
+Now this very extraordinary and rare auditory memory was developed in an
+altogether abrupt way. Inaudi, the son of poor peasants of Piedmont,
+passed the first years of his life as a shepherd. At the age of six his
+wonderful faculty of calculating figures appeared. He did not know at
+this time how to read or to write. At eleven years of age he astonished
+the members of the Anthropological Society of Paris by his phenomenal
+memory, and it was only much later, at the age of twenty, that he learnt
+to read and write. Neither of the parents of Inaudi had shown in the
+slightest degree a calculating faculty like that of little Jacques. It
+must then be admitted that it was developed as suddenly as the new
+qualities in the Evening Primrose that we have already mentioned.
+
+The first men, also, were probably ingenious children, born of
+anthropoid parents. This hypothesis very well explains the fact that man
+is more like the fœtus and the young of anthropoid apes than the adult
+animals, and exhibits only a trace of many organs which are much more
+developed in simian species.
+
+A very distinguished German anatomist, Wiedersheim,[66] has given in a
+pamphlet a _resumé_ of our actual knowledge of the organs of man from
+the point of view of their descent. He has found fifteen organs which
+show in the human species a considerable advance on those of anthropoid
+apes. The chief of these are the lower limb, well adapted for a constant
+erect carriage of the body; the strengthening of the pelvis and of the
+sacrum, as well as the broadening of the more slender pelvis of the
+female; the curvature of the lumbar part of the vertebral column; the
+development of the buttocks and of the calves; the difference of certain
+muscles of the face; the nose; certain strands from the brain to the
+spinal cord; the occipital lobe of the brain; the greater development of
+the cerebral cortex, and, lastly, the considerable differentiation of
+the muscles of the larynx which permit speech.
+
+But besides these progressive organs, Wiedersheim has counted seventeen
+decaying organs, still able to fulfil their physiological function in a
+more or less incomplete manner (amongst these are the decadent muscles
+of the leg and foot; the eleventh and twelfth pairs of ribs, the toes,
+the cæcum, etc.), and not less than one hundred and seven rudimentary
+organs which serve no useful physiological purpose (to this category
+belong the coccyx—the vestige of a tail—the thirteenth pair of ribs in
+the adult, the muscles of the ear, the vermiform appendage, etc.).
+
+We have already shown in the preceding chapter the great importance of
+rudimentary organs as aids to the tracing of the genealogy of organisms.
+These organs, useless at present, are the vestiges of similar but more
+developed organs, which fulfilled a useful function in our ancestors.
+
+The extraordinary quantity of rudimentary organs in man furnishes
+another proof of his animal origin, and puts at the disposal of science
+information of great value for the philosophic conception of human
+nature.

+
+
+Although he is a recent arrival on the earth, man has made great
+progress as compared with his ancestors, the anthropoid apes. A
+comparison between even the lower races of man, such as the Hottentots
+or the aborigines of Australia and higher types such as the inhabitants
+of Europe and of North Africa, shows that a very great advance has been
+made.
+
+Human art has been able to surpass nature in many instances. No natural
+sound is so perfect as some of the more beautiful pieces of modern
+music. Even in the production of form, man has triumphed over nature.
+Breeders of flowers or of birds seek to produce new varieties. With this
+object they often frame a conception of what they desire to produce,
+and, so to speak, set about to realise their programme. They prepare
+ideal images to serve them as guides in the process of production. By
+the method of artificial selection they often succeed in their wishes,
+and add to their collections some remarkable form. In such fashions
+aviculture and horticulture have produced birds and flowers more
+beautiful than any found in nature.
+
+In regard to the human body, attempts have been made to surpass nature
+and to represent a body corresponding to an artistic ideal. To arrive at
+something more beautiful than man, the wings of birds or the characters
+of some other creatures have been added to his presentment. Such
+attempts have had no other result than to show that the human form, as
+created by nature, cannot be surpassed. The ancient conception of the
+human body as the artistic ideal has been fully justified. The views of
+those religious fanatics who have thrown contempt on the body by
+representing it in degraded forms, must be rejected.
+
+It is impossible, however, to apply this result to our conception of the
+nature of man in general. The beautiful form of the human body appears
+only in youth and in maturity. In old age, the bodies of men and women
+are generally ugly, and in extreme old age it is almost impossible to
+see the traces of former beauty.
+
+Nor can conceptions of perfection drawn from the human face and body be
+extended to the whole of man’s organisation. A glance at some of the
+organic systems will make this plain.
+
+The human skin is covered with little hairs, the history of which is
+interesting. In one stage of embryonic life nearly the whole of the body
+is clad with hairs. This covering is known as the _lanugo_, and consists
+of strands of hair, disposed very regularly all over the body, save on
+the nose and the hands and feet. There is no doubt but that this is
+functionless, and is no more than an inheritance from the old ape-like
+condition. Later on, it falls out and is replaced by the ordinary downy
+covering of the body. In adult life, and particularly in old age, the
+hairs of the second coat tend to grow very long and so to form a
+covering that is neither beautiful nor in the least degree useful. We
+may take this as a first example of a disharmonious condition in the
+human body. Hairs, incapable of protecting the body from cold, survive
+merely as an ancestral relic and may become even harmful.
+
+The human skin is constantly exposed to the microbes in dust; and the
+follicles of the hairs, in which these microbes lodge, form receptacles
+very favourable to their multiplication. In the hollows of the
+follicles, certain microbes, as for instance some of the
+_Staphylococci_, multiply rapidly and give rise to acne and to pimples.
+The process may even go the length of producing a chronic skin-disease
+very unpleasant and even dangerous if it be associated with suppuration.
+
+In the human race, intelligence, that is to say, the activity of the
+brain, supplants many other functions, and man is able to protect
+himself against the inclemencies of weather much better than his furry
+ancestors were capable of doing. He is able to do this through his
+invention of clothing which may be varied with the nature of the
+weather. But the obstinate laws of inheritance burden him with a
+covering of hair, not only useless but frequently harmful. And this is
+only one example among many.
+
+Although, in an extreme case, man is able to survive the total loss of
+the teeth, it cannot yet be said that teeth are useless or harmful. None
+the less, a study of the human dentition reveals that this set of organs
+is out of harmony with the fundamental needs of our race. The monkeys of
+the old world (_Catarrhines_), although they belong obviously to the
+brute creation, already exhibit a tendency to reduction in the number of
+teeth. While American monkeys (_Platyrrhines_) may possess thirty-six
+teeth, the old world forms do not possess more than thirty-two in all,
+at least as a normal occurrence. Selenka[67] has shown that among
+gorillas and ourangs individuals with a fourth pair of molars, bringing
+up the number of teeth to thirty-six, are not rare. He found these
+additional molars in 20 per cent. of one hundred and ninety-four adult
+skulls of ourangs. On the other hand, in the cases of the chimpanzee and
+the gibbon, the third pair of molars differ from the others in smaller
+size and occasional absence. This reduction is to be associated with the
+smaller jaws and less powerful mastication of these anthropoids.
+
+Cases of supplementary molars are very rare in man, and occur more
+frequently in the lower races, such as negroes, Australians, and natives
+of New Caledonia.[68] On the other hand, absence of the third pair of
+molars, that is to say, of the wisdom teeth, is quite frequent,
+especially in the white races. Nearly 10 per cent. of Europeans
+throughout their lives have no more than twenty-eight teeth, the wisdom
+teeth being absent. This absence is more common in the upper jaw, where
+it occurs in from 18 to 19 per cent. of men. The loss of the wisdom
+teeth[69] is on the whole to be regarded as an advantage. Certainly from
+the “physiological point of view the part played by the wisdom teeth is
+subordinate. Their power of masticating is feeble; the loss does not
+appreciably interfere with mastication. The complete absence of all four
+has no influence on mastication.”[70] These teeth are cut very late,
+often not appearing until the thirtieth year and sometimes being delayed
+to extreme old age.
+
+Even if they were only useless, the wisdom teeth would furnish an
+instance of disharmony in the human body. But these teeth often are a
+source of trouble which, although it is not often serious, may lead to
+grave diseases and even to death. No other teeth are so subject to
+accident. This is due partly to the slowness with which they develop and
+to the difficulty they encounter in cutting the mucous membrane. Dental
+caries, moreover, is specially frequent in them.[71] The membrane
+surrounding them is specially subject to small lesions by which the
+infection spreads to adjacent parts. Inflammatory conditions frequently
+arise from these teeth, and tumours, caries of the jaw-bone and even
+diffused suppuration, leading to death, may be sequelæ of wounds of the
+wisdom teeth. Galippe[72] has described a case in which one of these
+teeth, failing to cut the gum in the normal position, made its way
+through the cheek. This produced an inflammatory suppuration of the
+cheek with numerous fistulæ and an inflammation of the masseter muscle
+which made it impossible for the mouth to open. Notwithstanding the
+extraction of the wisdom tooth that had been the cause of all these
+troubles, the patient died of meningitis, which had started from the
+tooth. Other cases have been described in which a difficult eruption of
+the tooth led to formation of an abscess in the bone, from which there
+arose a fatal abscess of the brain.
+
+Wisdom teeth may be the starting-point even of cancerous tumours.
+Magitot[73] writes that very many neoplasms of the jaw may be traced to
+a source of origin in the socket of the wisdom tooth.
+
+There is no useful function of these teeth to set against their
+disadvantages. It was our remote ancestors, masticating hard food, that
+had the advantages of these additional teeth. In man they are
+rudimentary organs, and provide another proof of our simian origin.
+
+The cæcal or vermiform appendage is another rudimentary organ in the
+human body, and is interesting from many points of view. I have already
+referred to its importance as definite evidence of our origin from lower
+animals, and shown how striking is the resemblance of the human organ to
+that of the anthropoid apes. It consists of a thick wall, containing
+glands, a muscular layer and lymphoid clumps. That it performs no
+function useful to man is made clear by the existence of undisturbed
+health in persons from whom it has been removed. Thanks to the advances
+of modern surgery, this organ has been removed very often, and sometimes
+even in cases where it did not appear to have been diseased. In a great
+majority of the cases, the removal of the organ succeeded well, and the
+patients experienced no harm, but appeared to carry on all the processes
+of digestion with equal completeness.
+
+On the other hand, the cæcal appendage in man is frequently obliterated,
+there being no trace of the normal aperture, so that there is no
+connection between it and the general digestive cavity. According to
+Ribbert,[74] nearly one person in four possesses the appendage in an
+obliterated condition, the condition being particularly frequent in the
+aged. In young persons and infants the aperture of the appendage is
+usually open. In cases where there is no communication with the cavity
+of the digestive tract, the processes of digestion appear to be normal.
+It is logical to conclude that in the human being the function of the
+cæcum is either absent or very slight.
+
+Even in the anthropoid apes the appendage of the cæcum appears to be a
+rudimentary structure, with a function at most accessory to that of the
+lymphoid clumps. In lower old world monkeys the vermiform appendage does
+not usually exist, cases such as that of _Cercopithecus sabaeus_, in
+which it is present as a little boss, being rare. It is necessary to
+seek the purpose of this structure still lower in the scale of life. In
+some herbivorous creatures the cæcum is large, and ends in a portion
+richly provided with lymphoid tissue, and similar to the vermiform
+appendage. The rabbit and certain marsupials are good examples.
+Undoubtedly, in their cases, the portion of the digestive canal which
+corresponds to the vermiform appendage of man is active in the digestion
+of vegetable matter. The organ is a very old part of the constitution of
+mammals, and it is because it has been preserved long after its function
+has disappeared that we find it occurring in the body of man.
+
+Rudimentary organs for the most part display a congenital lack of the
+power of resistance, and, as Darwin suggested, for this reason they are
+frequently the seats of disease. When Darwin wrote his work on the
+“Descent of Man,” more than a quarter of a century ago, many fatal cases
+of inflammation of the appendage had not been recorded. Darwin quoted
+only two cases as known to him. Since then, appendicitis (the name given
+by American surgeons to the first acute or to the chronic inflammation
+of the appendage) has become a well-known disease in Europe and America,
+and occupies considerable space in treatises on the pathology of the
+digestive tract.
+
+To give an idea of the prevalence of appendicitis, I may mention that in
+a single Paris hospital (Hôpital Trousseau) four hundred and forty-three
+cases of the disease have been treated in the five years 1895–1899.[75]
+In many of these cases the subjects were infants, as these as a rule are
+much more subject to appendicitis than are the aged. According to
+Treves,[76] the well-known English surgeon, 36 per cent. of the observed
+cases were under twenty years of age. Among old men, on the other hand,
+appendicitis is a rare exception. The varying incidence of the disease
+at different ages no doubt depends on the fact that in old age the
+appendage is often obliterated. The more easy communication with the
+other portion of the gut may be, the more chance there is for
+inflammation to occur. As it has a muscular layer, the appendage is able
+to void its fœcal contents; and a Scotch surgeon, Parker Syms,[77] has
+seen an appendage that he had removed, in the act of writhing about like
+an earthworm. Such movements, undoubtedly, would aid the discharge of
+the contents of the cavity.
+
+The movements of the appendage, however, are usually feeble, and thus
+stagnation of the contents is common. Foreign matter is often found in
+the cavity, such as the pips of fruit, seeds, hairs, thorns, and in rare
+cases pins or even tin-tacks. Such bodies are capable of wounding the
+inner wall of the appendage, and so giving an opportunity to the
+microbes that abound in the digestive tube, with the result that
+microbial infection and inflammation of the organ is produced. Often,
+too, intestinal worms pass into the appendage and become the carriers of
+pathogenic organisms.
+
+Appendicitis is usually a grave disease, and is fatal in from 8 to 10
+per cent. of cases. It would be difficult to find anywhere else in the
+human body so flagrant a case of natural disharmony. The organ in
+question may be obliterated or removed without disturbance of function,
+and, moreover, in its normal condition is a frequent cause of serious
+illness!
+
+The vermiform appendage is not the only part of the digestive canal that
+is out of harmony with the maintenance of life and health. The cæcum
+itself, of which the appendage is only a portion, is degenerating in the
+human body, as I stated in the last chapter. The human cæcum, in fact,
+is very little developed in comparison with the cæcum of most
+herbivorous animals, in which it is a true organ of digestion. In the
+human embryo the cæcum and the appendage are relatively better developed
+than they are in the adult.
+
+Disharmony is exhibited in the human body not only by rudimentary organs
+such as the wisdom teeth and the appendage, or by degenerating organs
+such as the cæcum. Some very large parts of our alimentary canal must be
+regarded as useless inheritances, bequeathed to us by our animal
+ancestors. It is no longer rash to say that not only the rudimentary
+appendage and the cæcum but the whole of the large intestine are
+superfluous, and that their removal would be attended with happy
+results. So far as digestion goes, the latter portion of the alimentary
+tract is of little importance. Even from the point of view of absorption
+of the products of digestion its importance is strictly secondary. And
+so it is not astonishing to find that the removal or disappearance of
+nearly the whole of the large intestine can be supported well by man.
+
+As one result of the astonishing progress of surgery, it has been found
+possible to excise certain parts of the gut, and particularly of the
+large intestine. Thus, in one case, Körte[78] removed, along with part
+of the small intestine, a considerable part of the large intestine,
+leaving in place only the terminal portion. The patient, who underwent
+eight successive abdominal operations, recovered. In the case[79] of
+another patient, operated on by Wiesinger, two coils of the large
+intestine (the transverse and descending colons) which were ulcerated,
+were isolated from the remainder of the gut, while the upper portion of
+the large intestine (the cæcum and the ascending colon) was sutured to
+the rectum. In spite of these serious interferences with natural
+structure, the patients recovered, and appeared to derive great
+advantage from the loss of the large intestine.
+
+I have quoted only two out of many similar cases. However, apart from
+surgical evidence, there exists proof of the uselessness of the large
+intestine in man. The best argument in favour of the proposition may be
+drawn from the case of a woman who for thirty-seven years discharged the
+waste matter from the alimentary canal through an intestinal fistula.
+The latter had opened spontaneously, as the result of an abscess seated
+on the right side of the abdomen. Her complaint, however, had not
+prevented her from marrying, from bearing three children, nor from
+pursuing an arduous calling. The person in question, who was a workwoman
+in Varsovie, was examined by a surgeon, M. Ciechomski,[80] thirty-five
+years after the establishment of the fistula. The surgeon proposed to
+operate, hoping to restore her to the normal condition, and the woman
+consented. However, when the abdominal cavity was opened, it appeared
+that the large intestine had atrophied along the whole length, from the
+cæcum to the rectum; the inner orifice of the fistula had passed into
+the digestive tract above the cæcum, opening into the small intestine.
+In the circumstances it was impossible to close the fistula, and the
+surgeon had to close up the abdominal wall, leaving the patient in her
+former condition. The woman recovered rapidly, and continued her usual
+mode of life. She came under observation again two years later, but
+since then had been lost sight of. The fact that a human being was
+capable of carrying on an apparently normal life for thirty years in the
+absence of a large intestine is good proof that the organ in question is
+not necessary to man, although it has not yet become rudimentary. In
+this case again, to find the useful stage of the structure, we have to
+go to our remote ancestors.
+
+The large intestine is much better developed in most herbivorous mammals
+than it is in carnivorous forms. Although it is useless in the digestion
+of animal food, it has an undisputed importance in the digestion of
+vegetable matter. It has a very large calibre in herbivorous creatures,
+and the voluminous cavity contains quantities of microbes which are able
+to digest cellulose. As cellulose is a material that resists the
+ordinary processes of digestion, it is easy to see the advantage derived
+from the harbouring of the microbes. It is more than probable that in
+the horse, the rabbit, and in some other mammals, that live exclusively
+on grain and herbage, the large intestine is necessary for normal life.
+
+On the other hand, the large intestine discharges a function similar to
+that of the urinary bladder. The urine, which is being secreted
+continuously by the kidneys, accumulates in the large reservoir provided
+by the bladder. Similarly the waste matter from the processes of
+digestion accumulate in the large intestine and remain there for a
+longer or shorter period.
+
+In studying the natural history of the large intestine, it striking that
+this portion of the gut is well developed only among mammals. These
+animals, for the most part, lead an extremely active terrestrial life.
+Most of them have to move about very quickly, the predacious forms in
+pursuit of their prey, the herbivorous forms to escape from their
+enemies. In such a mode of life, the need to stop in order to empty the
+intestines would be a serious disadvantage, and the possibility of
+retaining the dejecta in a large reservoir would be very useful.[81]
+
+Such are the causes that have determined the growth of the large
+intestine among mammals. Birds, which live, so to speak, in the air, and
+which do not need to arrest their locomotion in order to void their
+excreta, have no large intestine. Reptiles and amphibia, although they
+live a terrestrial life, do not require a voluminous large intestine,
+and such is not found among them. These animals do not have a fixed
+temperature; they are what we know as “cold-blooded,” and in consequence
+are small eaters. Most of them are sluggish, and do not lead an active
+existence like that of mammals.
+
+In the legacy acquired by man from his animal ancestors, there occur not
+only rudimentary organs that are useless or harmful, but fully developed
+organs equally useless. The large intestine must be regarded as one of
+the organs possessed by man and yet harmful to his health and his life.
+The large intestine is the reservoir of the waste of the digestive
+processes, and this waste stagnates long enough to putrefy. The products
+of putrefaction are harmful. When fæcal matter is allowed to remain in
+the intestine, as in cases of constipation, a common complaint, certain
+products are absorbed by the organism and produce poisoning, often of a
+serious nature. Every one knows that a high temperature may be the
+result of constipation in women after childbirth, or in patients
+recovering from an operation. This is due to an absorption of substances
+produced by the microbes of the large intestine. Similar products may be
+the cause of an attack of acne or of other skin diseases. In fine, the
+presence of a large intestine in the human body is the cause of a series
+of misfortunes. The organ is the seat of many grave diseases, among
+which dysentery is notable. In some tropical climates dysentery is a
+serious scourge. According to Rhey,[82] it is “the greatest danger to
+which a European is subjected in Tonkin. It is responsible for more than
+30 per cent. of the deaths caused by disease.” European troops pay it a
+large annual toll in the colonies of the French and English.
+
+Malignant tumours seem to display a predilection for this region of the
+digestive tract. Thus, among 1148 cases of cancer of the alimentary
+tract recorded in the Prussian hospitals in 1895 and 1896, 1022, or 89
+per cent., affected the large intestine, including the rectum and
+cæcum.[83] The small intestine is the only part of the digestive tract
+that is indispensable, and it is attacked to a much smaller extent,
+providing only 11 per cent. of the cases of intestinal cancer. The
+probable explanation of these facts is that the contents of the gut
+remain in the small intestine a shorter time than in the large.
+
+Stagnation is a familiar cause of disease, and is the probable cause of
+the frequency of cancer of the stomach. Of 10,537 cases of cancer of all
+parts of the digestive tract recorded in the Prussian hospitals in the
+same period, 4288, or more than 40 per cent., affected the stomach. The
+latter organ is one that the human body would do well to be rid of. It
+is not so useless as the large intestine, since it is the chief seat of
+digestion of albuminous substances, but the small intestine could take
+its place. Moreover, cases are known in which surgeons have removed
+cancerous stomachs. The results of such operations were favourable, to
+the extent that the patients survived and were able to absorb sufficient
+nourishment. They had to eat rather more frequently, and performed the
+processes of digestion by means of the secretions of the small intestine
+and pancreas.
+
+It is not surprising to find so many instances of useless or harmful
+organs in the alimentary tract. Our ancestors were creatures that fed on
+crude and rough materials, such as wild plants and unprepared flesh. Man
+has learned to cultivate plants that are digested easily, and to prepare
+his meats in such a fashion as to be readily digested. The organs that
+were adapted to the mode of life of the animal predecessors of man have
+become to a large extent superfluous. Many creatures that have found the
+opportunity of obtaining their nutriment in a highly digestible
+condition have lost, more or less completely, the digestive organs. Many
+parasites are instances of this, as for example the tape-worms, which
+live in the human digestive tract, bathed by a nutritive fluid which
+they absorb directly; they have lost the digestive tract completely.
+
+In the case of man such an evolution has not occurred, and there remains
+in the body a harmful organ like the large intestine. In consequence, it
+is impossible for him to take his nutriment in the most perfect form. If
+he were only to eat substances that could be almost completely absorbed,
+the large intestine would be unable to empty itself, and serious
+complications would be produced. A satisfactory system of diet has to
+make allowance for this, and in consequence of the structure of the
+alimentary canal, has to include in the food bulky and indigestible
+materials such as vegetables.
+
+At this point I may refer to a topic of considerable general interest.
+Animals, in the choice of food for themselves or for their young, are
+guided by a blind and innate instinct. As I have shown in my second
+chapter, creatures like the fossorial wasps select only particular
+species of spiders or insects. Instinct directs them to the kind of food
+best suited to the wants of their progeny. Bees are attracted by the
+sweet juices of flowers; the silkworm instinctively devours the leaves
+of the mulberry and rejects most other plants. In higher animals,
+instinct plays the chief part in the choice of food. The difficulty of
+getting rats to eat poisoned food is well known; an instinct warns them
+of the danger of the material offered to them. In the same way dogs
+refrain from food that has been poisoned.
+
+Every one has seen the minute attention bestowed by a monkey on food
+before beginning to eat it. It turns over what is offered, smells it
+carefully, cleans it, and before beginning to eat, subjects it to an
+examination that seems to us ridiculous. Monkeys often throw away food
+without even biting it. None the less, in spite of an instinct so highly
+developed, monkeys poison themselves with all sorts of dangerous
+substances, even when these exhale a strange odour. I have seen monkeys
+die poisoned by the phosphorus of matches, or even by iodoform which
+they had contrived to steal.
+
+In the case of man, aberrations of instinct in the choice of food are
+common. As soon as babies begin to walk, they lay hold of everything and
+try to eat it. Bits of paper, lumps of sealing-wax, the mucous matter
+from the nose, all appear to them to be things to eat. Constant guard
+has to be kept to prevent them from doing themselves an injury. Fruits
+and berries they cannot resist. Cases of poisoning very naturally are
+extremely frequent, and as every one must know of instances, I shall
+mention only a single case. “Messrs. Beadle and Sons, oil manufacturers
+at Boston, had thrown out, from the door of their establishment, a
+quantity of castor beans that were decayed and useless. Some children
+playing in the street mistook the seeds for pistachio nuts, and shared
+them with their friends. All the children seem to have eaten of them,
+with the result that more than seventy showed serious symptoms of
+poisoning.”[84]
+
+The consumption of ergotised rye and of maize contaminated with certain
+leguminous plants (_Lathyrus_) frequently produces epidemics of
+poisoning without instinct intervening to protect the victims.
+
+While the large intestine, acting as an asylum of harmful microbes, is a
+source of intoxication from within, the aberrant instinct of man leads
+him to poison himself from without with alcohol and ether, opium and
+morphia. The widespread results of alcoholism show plainly the prevalent
+existence in man of a want of harmony between the instinct for choosing
+food and the instinct of preservation.
+
+The digestive apparatus, then, affords abundant proof of the
+imperfection and disharmony of our nature. Moreover, there are many
+other proofs, as I shall show in the chapters to follow.

+     _Remarks on the disharmonies in the human organs of sense and
+perception.—Rudimentary parts of the reproductive apparatus.—Origin and
+                         function of the hymen_
+
+The digestive organs are not alone amongst the parts of the human body
+in exhibiting a greater or lesser disharmony. More than fifty years ago,
+a great German physiologist, Johannes Müller, showed that although the
+human eye was regarded as a very perfect organ, its power of correction
+for aberration of light was poor. Helmholz, another famous German man of
+science, stated that the optical study of the eye brought complete
+disillusion. “Nature,” he said, “seems to have packed this organ with
+mistakes, as if with the avowed purpose of destroying any possible
+foundation for the theory that organs are adapted to their environment.”
+Not only the eye, but the other organs by means of which we are
+conscious of the outside world, present natural disharmony. Therein lies
+the cause of our want of certainty about the sources of our perceptions.
+Memory, the faculty that registers our mental processes, becomes active
+much later than other faculties lodged in the brain. If the new-born
+human child were relatively as well developed as the young guinea-pig,
+it is probable that we should know far more as to the history of our
+consciousness of the external world. But without lingering over the
+disharmonies in our senses and faculties, I shall pass at once to a
+consideration of the apparatus for maintaining the species.
+
+I have shown that the alimentary tract, the chief organ involved in the
+maintenance of the individual life, affords no proof of the theory that
+human nature is perfect. Is it the case that the organs of reproduction
+give a better result? When I wished to describe the most perfect
+examples of harmony to be found amongst plants, I chose the mechanism by
+which fertilisation is accomplished in flowers. The persistence of the
+species is secured, in the case of flowers, by a marvellous series of
+structures and functions.
+
+Is the maintenance of the human species similarly provided for? A
+detailed investigation of the male and female human reproductive organs
+shows that these contain parts of diverse origin. The apparatus contains
+portions of extremely ancient origin, and portions that have been
+acquired recently. The internal organs display traces of a remote
+hermaphroditism. In the male, there occur traces of the female
+apparatus, rudiments of the uterus and fallopian tubes. In the female,
+on the other hand, rudiments of the male structure persist. These traces
+date very far back in the history of the race, for they occur also in
+most other vertebrates. The facts seem to indicate that, at a very
+remote period, the ancestral vertebrates were hermaphrodite, and that
+they became divided into males and females only gradually, still
+retaining in each sex traces of the other sex. Such traces occur
+frequently, even in adult man, in the form of rudimentary organs (known
+as the organs of Weber, of Rosenmüller, and so forth). The rudiments not
+only are functionless but sometimes, as frequently happens with
+atrophied structures, form the starting-point of monstrous growths, or
+of tumours that interfere with health. Thus the hypertrophy of a part of
+the male prostate gland (the organ of Weber) brings about the formation
+of a _uterus masculinus_, and so produces a sort of abnormal
+hermaphroditism. The rudimentary organs in the male reproductive
+apparatus frequently are the starting-points of hydatid cysts. In the
+female, cysts such as those of the _parovaria_ are produced by the
+proliferation of rudimentary structures. These, although usually benign,
+not infrequently become malignant. Lawson Tait,[85] a celebrated English
+surgeon, has published a case of this kind. He removed from a young
+woman a parovarian cyst that was apparently benign, but in six weeks
+symptoms of cancer arose, and the patient died of cancer in three
+months.
+
+A comparison of the rudimentary organs in the human reproductive
+apparatus with those in the similar structures of lower animals, shows
+that many relics have degenerated further in man than in other animals.
+Thus the duct of the embryonic kidney (known as the Wolffian body) is of
+rare occurrence in adult man, although it is retained throughout life in
+the case of some herbivorous animals, in which it is known as Gaertner’s
+duct. There are, however, many rudimentary organs in the human
+reproductive apparatus, organs that are always useless and not
+infrequently more or less harmful to health and life.
+
+Alongside organs which have been useless from time immemorial, the
+reproductive system of man possesses structures of recent acquisition.
+These deserve special attention, as it might have been supposed that in
+them would have been found special instances of adaptation to the
+reproductive function.
+
+I have already referred (chap. iii.) to the discussions that have taken
+place over the simian origin of man. All attempts to demonstrate the
+presence in the human brain of parts that were absent in the simian
+brain have failed. It is a curious fact that man displays a more marked
+difference from monkeys in the structure of the reproductive system than
+in the structure of the brain. There is no _os penis_ in man. This bone,
+which facilitates intromission, occurs in many vertebrates, not only
+among rodents and carnivora, which are widely separated from man, but in
+many monkeys, and most notably in anthropoid apes.[86] For some reason
+impossible to establish, man has lost this bone. It may be that certain
+ossifications of most rare occurrence[87] may represent an atavistic
+inheritance from our remote ancestors.
+
+In the male sex the difference between man and the anthropoid ape is the
+loss of an organ; in the female sex it is the acquisition of an organ.
+The hymen, the physical indication of virginity, is peculiar to the
+human race. That organ would serve the purpose of those disputants who
+make every effort to discover the existence of a structure peculiarly
+human, far better than the posterior lobe of the brain, or the
+hippocampus minor. Bischoff[88] has determined its absence in the
+anthropoid apes, and his result has been confirmed by other observers.
+Deniker[89] failed to find it either in the fœtal gorilla or in the
+young gorilla. In the case of the fœtus of the gibbon, he found a slight
+elevation round the entrance to the vagina “which might be homologised
+with the hymen,”[90] but which, however, was not the membrane in
+question. Deniker[91] himself decided that the “membrane was absent in
+anthropoid apes at all ages.” Weidersheim, in his summary of the
+organisation of the human body,[92] also sets down the fact that “in
+monkeys a hymen is not present.”
+
+The fact that this structure appears late in the development of the
+female fœtus bears out the supposition that it has been acquired
+recently by the race. According to several observers, who agree in this
+matter, the membrane does not develop until at least the nineteenth week
+of fœtal life.
+
+Although organs very ancient in origin, and now become degenerate
+rudiments, may be useless, it is to be expected that an organ of recent
+appearance and still in a progressive condition, would have an important
+function. Of what utility is this membrane to a woman? Wiedersheim[93]
+remarks that its function has not been made out.
+
+The hymen sometimes plays a large part in family and social relations,
+and, regarded as the evidence for virginity, has had moral significance
+bestowed on it. A minute examination of this structure is frequently a
+part of the judicial procedure in cases of supposed rape and so forth.
+The destruction of the hymen has led to the death of many hundreds of
+men and women.
+
+From our point of view, however, it is the possible physiological
+function of this structure that is interesting. It seems impossible to
+conclude otherwise than that in existing races it has practically no
+functional value. Its atrophy as the result of sexual congress not only
+is no bar to sexual relations, but removes an unpleasant impediment. In
+many races the structure is removed as soon as possible. In some parts
+of China it is destroyed as part of the toilet of young children, and
+indeed many Chinese physicians are ignorant of its existence. A similar
+state of affairs occurs in some parts of India. In Brazil, among the
+tribe of Machacuras, virgins, in the European sense, do not exist, for
+the mothers destroy the hymen in female children soon after birth. In
+Kamchatka the aborigines regard it as disgraceful to be married with the
+hymen intact, and the mothers operate on their daughters.[94] Among
+other races, again, the disagreeable duty of defloration is assigned to
+special persons. Among the natives of the Philippines there formerly
+existed well-paid public officials the duty of whom was to destroy the
+virginity of the girls and so to make marriage pleasanter for the
+husbands. A similar custom occurs among the inhabitants of New
+Caledonia, and Moncelon states that there virginity is held in little
+esteem. “I have proof of the curious circumstance,” he wrote, “that when
+a husband shrinks from destroying the virginity of his wife, he employs
+some one from a regular profession to take his place.”
+
+Such examples, selected from amongst many, may be taken as proof that
+even such a peculiar and recently acquired organ has not a physiological
+use.
+
+On the other hand, especially among Christians and Mahomedans, the
+existence of the hymen in an intact condition is regarded as very
+important. The ancient Jews began to set a high value on virginity.
+According to the old Mosaic law, if, at the time of her marriage, a
+young girl were found to be no longer a virgin, “Then they shall bring
+out the damsel to the door of her father’s house, and the men of her
+city shall stone her with stones that she die; because she hath wrought
+folly in Israel, to play the whore in her father’s house” (Deut. xxii.
+21). The religions that have sprung from Judaism have retained this old
+view of virginity, although in an attenuated form. Among some Christian
+peoples, material proofs of virginity at the time of marriage are
+demanded, and among some Mahomedans such proofs are exhibited to friends
+and relations on the day after marriage. However, the actual defloration
+is not always left to the husband, but among Arabs and Copts and amongst
+the natives of Egypt, the operation is performed by a specially selected
+matron.[95]
+
+It is plain, then, that this membrane is of no direct service in the
+sexual process. It may even give rise to more or less serious
+misfortune. Thus, when it is unusually rigid, the adjacent peritoneum
+may be torn and the results may be disastrous. Occasionally the rupture
+of an abnormally vascular membrane may give rise to bleeding of a
+prolonged and even fatal character.[96] Moreover the membrane is a
+frequent seat of ulcers, specific or otherwise.[97]
+
+I have already mentioned that among some races a rigorous toilet
+involves the destruction of the hymen. It is plain that the existence of
+the membrane interferes with strict hygiene of the vagina, especially at
+the periods. Probably some blood is retained by the membrane and
+furnishes a soil for microbes that may be dangerous to health. It is
+quite possible that certain forms of anæmia, as for instance the
+chloranæmia of virgins, may be produced by microbial growth. This would
+easily explain why marriage is the readiest cure for such anæmia, as
+marriage involves destruction of the membrane, and so makes possible the
+complete discharge of fluid from the vagina.[98]
+
+What then can be the meaning of this organ, useless as it is for the
+sexual functions, sometimes dangerous to health, an organ that is no
+ancestral heritage and that must be destroyed by the act of sexual
+union? Formerly, when it was accepted that characters acquired in
+individual life could be transmitted to offspring, the question was
+asked as to why this membrane had not disappeared. The instance was one
+of those which helped to overthrow the dogma of the inheritance of
+acquired characters.
+
+Although it is useless to existing man, this organ may yet come to be
+explained by science. As yet we have to fall back on suppositions. The
+hypothesis which seems most probable is that in the earlier period of
+the existence of the human race, sexual relations were begun at a very
+early age, before the male organs were mature. Under such circumstances
+the hymen would not only not have been a barrier, but would have made
+congress more satisfactory. Gradually the hymen would have become
+dilated without being torn, until it was capable of admitting the adult
+organ. This hypothesis implies that in early times the membrane was not
+brutally torn, but that it was gradually dilated and that violent
+rupture is a modern necessity. In support of the hypothesis it may be
+mentioned that amongst certain living races sexual union begins at a
+very early age. In Ceylon, marriage takes place when the boys are from
+seven to ten years old and when the girls are from four to six years,
+according to Roer, or about eight years according to Beierlein. After
+the actual wedding ceremony the bride returns to the house of her
+parents, and it is only a few years later, when she is adult, that she
+goes to her husband. Roer states that he has seen cases where a father
+and son were attending school together.
+
+Among the Vedas, a low caste of tropical India, boys marry at the age of
+from fifteen to sixteen years, certainly before the sexual organs have
+attained their full dimensions. The missionary Etern was struck with the
+agitation of the natives of Keradif (in Abyssinia) when they were
+ordered within fourteen days to marry all their boys more than fourteen
+years old to girls more than nine.[99] In Madagascar, in the beginning
+of the seventeenth century, it was the custom for boys to marry at an
+age of from ten to twelve years. The natives of German New Guinea marry
+their boys at the age of fourteen to fifteen. Even in England a law
+still exists permitting marriage to boys fourteen years old. The law is
+now a dead letter, but is evidence of the ancient practice.
+
+It is known that even at the present time the hymen is not always
+ruptured in sexual congress. Budin has recorded its existence in
+seventeen per cent. of primiparous women. Among seventy-five cases of
+women in their first confinements he found the hymen intact in thirteen
+cases. Since provision for children has fallen on fathers these have
+taken to deferring marriage to a later age than when children were left
+to the mother. That is the probable reason why there are now fewer
+married boys. Thus, formerly, the proportion of women who at the first
+childbirth still possessed unruptured hymens, was much greater, and it
+is not difficult to suppose that in still earlier times such a condition
+was normal. It is plain that there is here an instance of a very
+recently acquired disharmony.
+
+The homology between certain portions of the male and female
+reproductive apparatus is well known. The male homologue of the female
+hymen is a little fold that hinders the mingling of urine with the
+seminal fluid during emission, and that is known to anatomists as the
+_caput gallinaginis_ or _colliculus seminalis_. It is very much smaller
+than the hymen, so that we cannot regard the latter as a rudimentary
+homologue of a useful organ. However, the prepuce of the male is a clear
+instance of the presence in the male organs of useless parts. It is
+removed by circumcision among very many races, such as the Hebrews and
+Arabs, and other Mahomedans, and amongst Persians, negroes, Hindus,
+Tartars, and its absence seems to bring about no inconvenience.

+ marriage among primitive and uncivilised races.—Disharmony between age
+of puberty and age of nubility.—Age of marriage.—Examples of disharmony
+           in the development of the reproductive function._
+
+Notwithstanding their imperfections, the human organs of reproduction
+are able to fulfil their functions. A close scrutiny, however, shows
+that there are many sides on which they are disharmonious or badly
+adapted.
+
+The occurrence of bleeding is usually a sign of disease. Bleeding from
+the nose or of the lungs or intestines or kidneys is an indication of
+disease more or less serious. Discharge of blood from the female
+reproductive organs may also be an indication of disease, as for
+instance when due to tumours of the uterus. The only exception to the
+rule is the periodic flow in the case of women, by which they lose
+hundreds of grammes of blood (100 to 600 gr.). There is something
+paradoxical in such a physiological occurrence, and it deserves minute
+consideration.
+
+These periodic losses, unlike the possession of a hymen, are not a
+peculiarity of the human female. “Heat” in lower animals is analogous,
+although in that case the chief indications are swellings of the mucous
+membrane with a slight discharge of fluid, hardly tinged with blood. The
+state indicates the awakening of the sexual instinct and readiness for
+coition.[100] Among monkeys there has been observed a flow much more
+closely resembling that of woman. In the case of macaques and
+cercopitheci, it has been observed even that the flow is monthly.
+Heape,[101] while in British India, took advantage of a valuable
+opportunity for making observations on this subject.
+
+Among two hundred and thirty females of _Macacus rhesus_ of which the
+greater number were adult or nearly so, seventeen displayed signs of
+menstruation, consisting of a swelling of the genitalia accompanied by
+the discharge of a pale and viscid fluid. Usually the flow assumed a
+pale rose tint, due to the presence in it of blood corpuscles, but cases
+where it was highly coloured were rare.
+
+Although they are distinctly analogous to the menstrual flows of women,
+these occurrences in monkeys are distinguished by the predominance of
+the swelling of the genitalia, the viscid character of the discharge,
+and the relative absence of blood. They present a condition intermediate
+between the “heat” of lower animals and the human phenomena.
+
+In anthropoid apes a similar menstruation has been observed. Bolau,
+Ehlers, and Hermes, record it in the case of the chimpanzee. “At this
+period,” wrote Hartmann,[102] “swelling and reddening of the genitalia
+occurred. The labiæ majores, which are usually inconspicuous, enlarged
+greatly, and a similar increase took place in the labiæ minores and the
+clitoris.”
+
+In the case of women swelling of the genitalia is very slightly marked,
+and the chief occurrence is the flow of blood. It is plain, then, that
+something new has been acquired in the menstruation of women.
+
+The condition of the flow at the present time is probably the result of
+modifications acquired recently in the history of the race. Among
+primitive peoples sexual union occurred at a very early age, and
+pregnancy occurred before menstruation. The latter did not appear during
+pregnancy nor in the time of suckling, and probably the latter was
+hardly over before a new pregnancy had occurred. In that way there was
+no opportunity for the onset of menstruation.
+
+The human capacity for procreation throughout the year made the race
+extremely prolific. Probably this prolificness is the reason why man has
+spread over the surface of the earth, and has multiplied so enormously,
+in spite of the barriers to his progress and the high rate of mortality
+to which he is subjected.
+
+Instances are known from recent observation of pregnancies occurring
+before the onset of menstruation. According to Rhode, among the Guatos,
+Indians inhabiting the mouth of the Rio Sâo Lourenzo in Paraguay,
+married women not more than five to eight years of age are to be met
+with, and these must have married before menstruation. Among the Vedas
+of tropical India, girls marry before they are nine years of age, and
+have relations with their husbands before sexual maturity. In Chiras in
+Persia, girls marry before puberty, and while their chests are still
+flat. In Syria, according to Robson, girls marry at the age of ten, and
+so before puberty. Du Chaillu related that the Achira of West Africa did
+not defer marriage until after the appearance of puberty. Abbadie, while
+on his voyage in Nubia, found that men bought young girls and had sexual
+relations with them before the time of menstruation. Among the Atjeh of
+Sumatra, girls marry at an age certainly before that of puberty, as they
+have hardly lost their first set of teeth. Although the husbands are a
+few years older, they are still unfitted for sexual union. The couples
+sleep together, and attempt sexual union before they are fitted for it.
+Among the islanders of Viti, again, marriage takes place before puberty.
+
+The ancient Hindoos married at a very early age. Bötlingk quotes from
+the Sanscrit poems in which hell was awarded to the fathers of girls who
+had not been married when puberty came on. In other verses it was
+written that not only the father but also the mother and the elder
+brother were to be carried down into hell if the daughter began to
+menstruate before she had been married; the girl herself was to descend
+to the lowest degree of Çûdrâ, and was never to be taken as a wife.
+
+There is no doubt as to the possible fertility of marriages contracted
+at these early ages. Polak[103] gives examples taken from Persia. It is
+not necessary for impregnation that it should have been preceded by a
+menstrual flow. Facts making this clear have occurred not only in warm
+climates but in our own latitude. Rakhmanoff,[104] in Russia, attended
+in childbirth a woman not more than fourteen years of age, of poor
+constitution, and badly nourished, and with features still infantine.
+Menstruation had not yet taken place; the confinement was normal.
+
+It is reasonable to suppose that in former times these early marriages
+of girls under the age of puberty were more common, if indeed they were
+not customary. In such circumstances menstruation would have been a rare
+phenomenon.
+
+It must be remembered that the examples of menstruation observed in the
+case of monkeys were taken from creatures living in abnormal conditions,
+isolated in zoological gardens and passing their lives in captivity. It
+is highly probable that the periods as they exist to-day, with copious
+sanguineous discharge, are a recent acquisition of the human race.
+
+As he emerged from the primitive condition man had to restrain his
+prolificness. The history of savages and of civilisations shows that
+progress and culture have been accompanied by a rise in the age for
+marriage. In this way the menstrual periods could develop without check,
+and attain the present condition. In these circumstances it is not
+wonderful that menstruation should appear so abnormal and even
+pathological. A copious discharge of blood, preceded and accompanied by
+pain and by nervous and mental distress as so frequently happens, has no
+apparent kinship with the processes of normal life.
+
+It is now easy to see why among so many races there are special rules
+made for women during this period. Most of the races of the earth, says
+Ploss, regard menstruating women as impure. The occurrence is so
+widespread that it is unnecessary to adduce particular cases, but a few
+with some point of special interest may be noticed. Thus, among the
+Hindoos a high-caste woman is regarded as a pariah in the first day of
+the period, and as one of the murderers of Buddha on the second day.
+Among many races a woman in this condition is forbidden to come near
+men, or to touch a number of objects, as she is regarded as capable of
+setting up many diseases and of doing serious damage. The Germans of the
+eighteenth century believed that the hair of a menstruating woman buried
+in manure would engender snakes.
+
+It is not surprising that the origin of menstruation has been attributed
+frequently to evil spirits. The Iranians held that it appeared first in
+Dchahi, the goddess of immorality.[105] Such opinions implied vaguely
+that there was something abnormal in the process. The history of the
+evolution of menstruation explains well the origin of such a notion.
+
+Another bizarre and apparently abnormal feature of the reproductive
+processes receives explanation in the history of its evolution. The
+feature in question is the painfulness of childbirth. It is truly
+astonishing and singular to find a phenomenon essentially normal from
+the point of view of physiology accompanied by pain of so marked a
+character. No doubt other animals suffer during labour, but among the
+mammalia woman undergoes the severest pain.
+
+Observations made on several Europeans who have been brought to bed at
+an abnormally early age have shown that, contrary to all expectation,
+parturition was easy and the sequelæ normal.[106] Moreover, Dr. Dionij
+has stated his opinion that of two cases of a first childbirth at the
+ages respectively of fifteen and of forty years, he would prefer the
+earlier age. The daughters of the colonists in the Antilles were
+accustomed to marry at very early ages. In 1667 Du Tertre related that a
+young woman of that region had informed him that the birth of her first
+child took place when she was twelve years and a half of age, and that
+the process lasted no more than a quarter of an hour and had been
+painless. The missionary Beierlein practised for long in Madras, where
+marriages were very early, and found that parturition was much more easy
+than in Europe.[107]
+
+On the other hand, certain facts show that too young mothers are subject
+to a very heavy rate of mortality during childbirth, and soon after it.
+The most salient fact in this connection is furnished by Hassenstein,
+who has stated that the mortality of labour cases in Abyssinia is 30 per
+cent., and who has attributed this death-rate to the circumstance that
+marriage takes place before the body of the woman is sufficiently
+developed.[108] In British India the disadvantages of precocious
+marriage have been repeatedly urged; and in a petition relating to this
+subject, Dr. Mansell referred to the case of a woman of twelve years of
+age in whom parturition was interfered with by the undeveloped condition
+of the pelvis, so that the head of the child had to be destroyed.
+
+Matthews Duncan, the well-known English obstetrician, paid much
+attention to the mortality of labour cases, with the object of deciding
+the best age for marriage. He came to the conclusion that women from
+twenty to twenty-four years of age were best fitted for labour, that is
+to say, showed the lowest rate of mortality during labour or as a result
+of labour. He also showed that such women were most fertile, and that
+the development of the pelvic bones was completed at that period of
+life. Women who were of a lower or higher age showed a greater mortality
+rate in connection with childbirth.
+
+The facts of which I have just given a summary lead directly to a most
+striking instance of disharmony exhibited in the order of the
+development of the human reproductive apparatus. Puberty declares itself
+in a woman by the beginning of menstruation at a time when girls still
+possess infantile characters and when the bones of the pelvic basin are
+not yet fully developed. Obviously there is a disharmony between puberty
+and the general maturity of the body, that is to say, the nubile
+condition.
+
+This disharmony becomes still more evident upon a closer examination of
+the phases of development of the different reproductive functions. In
+the human race, reproduction is brought about by the union of the sexes
+suggested by sympathy or mutual love. The sexual union makes it possible
+for the male elements or spermatozoa to reach the eggs and fertilise
+them by passing into them. It might have been expected that the
+different steps in the process would have been attuned so as to act in
+harmony. As a matter of fact there is no such relation. The different
+factors of the sexual function develop independently and unharmoniously.
+
+Love and the sexual sense in the human race appear before the other
+factors in the process. Ramdohr,[109] in the eighteenth century, stated
+that little boys frequently exhibit amorousness towards women. They are
+capable of being strongly affected by jealousy and by desire of
+exclusive possession of the coveted woman. This fact is well known, and
+has been related of famous personages. Thus Dante, at the age of nine,
+fell in love with Beatrice; Canova was in love when he was little more
+than six years of age, and Lord Byron was in love with Mary Duff at the
+age of seven.[110]
+
+Sexual excitability appears at an age when there is no question but that
+the sexual elements are undeveloped. In infants still in the cradle,
+observers have noticed movements and attitudes showing the presence of
+sexual excitability. Curschmann and Fürbringer,[111] both competent
+clinicians, have noticed these feelings in children under the age of
+five. Later on in life, the development of the sensibility is more
+common, and is practically universal among boys before the time at which
+the spermatozoa are ripe.
+
+This disharmony is the cause of onanism, which is common everywhere
+among boys. Before ordinary sexual congress is possible for them, boys
+experience the characteristic pleasure of the sexual sensations, and by
+a kind of natural instinct learn self-gratification. Onanism is
+sometimes defined as a “gratification of the sexual desire by unnatural
+means.”[112] But it is man’s constitution itself that permits the
+development of the sensation precociously, before the development of
+sexual maturity. Letourneau is right when he says that such sexual
+aberrations are abnormal, but not unnatural, as they occur among
+animals.
+
+In the case of young boys the habit is so common that, according to
+Christian,[113] “very few are able to say that they have avoided it
+completely.” The same writer asks the question: “If it be remembered
+that onanism among certain peoples, at certain times, has been
+recognised as an ordinary event, it is difficult to avoid asking if
+there be not a latent vice, hidden in the depths of human nature, and
+ready to be provoked into activity by very small causes?” The answer is
+sufficiently plain. The cause of onanism, this “vice” or “crime,” as
+Tissot and other authors have called it, undoubtedly is the result of a
+natural disharmony in the human constitution, of a premature development
+of sexual sensation. Among the most civilised races and the lowest
+savages the mode of satisfying the premature demand is equally common.
+
+It is to be noticed that onanism is more common and earlier developed in
+the male sex. The development of sexual irritability in the female
+occurs very irregularly. In some races onanism is so much a custom among
+little girls that no attempt is made to conceal the practice. This
+occurs, for instance, among certain Hottentot tribes, and is referred to
+openly in talk and legends.[114] Similar instances occur elsewhere, but
+in most races the practice is thought wrong, and is concealed as much as
+possible.
+
+Among girls,[115] onanism is less frequent than in the case of boys, a
+circumstance in relation with the fact that sexual sensation usually
+appears much later in the female sex. It is almost a general rule that
+girls who have arrived at sexual maturity have not acquired sexual
+irritability, while to many it comes only gradually after marriage.
+Sometimes it does not occur until after the first child has been born.
+On the other hand, love begins very early in young girls, although it
+long retains a platonic character and is not associated with sexual
+sensation until much later.
+
+The maturity of the spermatozoa in the male comes long after the
+development of sexual irritability and of love. None the less, it comes
+before the organism of the male is actually ready. It happens, in
+consequence, especially among the highly civilised peoples, that
+marriage and regular unions are impossible at the right time. The youth
+has his education to finish, his profession to choose, and he must be
+ready to support children before he is able to marry. As civilisation
+advances, the age of marriage becomes later and later. In the case of
+Europeans, sexual maturity occurs in the male at the age of twelve to
+fourteen years, while the average age at the first marriage is shown in
+the following table:—
+
+                 _Table of Age at First Marriage._[116]
+
+      Nationality. Age in years of males. Age in years of females.
+      English                       25.94                    24.69
+      French                        28.41                    25.32
+      Norwegians                    28.51                    26.98
+      Dutch                         29.15                    27.78
+      Belgians                      29.94                    28.19
+
+These figures show clearly what a gap there is between the coming of
+sexual maturity and the age at which marriage can be undertaken.
+
+The decay of the reproductive functions shows a series of disharmonies
+similar to those that occur during development. Spermatozoa continue to
+be formed throughout the greater part of the life of a man, and may
+still be found even in very old men. Pawloff, for instance, discovered
+that they were present in abundance in the case of a man at the age of
+ninety-four, and this observation is not unique.[117] But the presence
+of ripe spermatozoa is not the only condition necessary for functional
+virility. In the case of old men it happens frequently that there is
+incapacity to make normal use of the spermatozoa that are produced. This
+brings about a series of discomforts in the sexual functions of advanced
+life which, however, do not prevent the retention of the specific
+sensation and desire until a very extreme old age. Doctors, in hospitals
+devoted to old men, have noticed to what an extent their patients are
+engrossed by sexuality. Even some of the ancient authors have noticed
+how the amorous sentiments of old men turn into a perverted attraction
+to youths.
+
+Sexual irritability and amorousness not only appear before sexual
+maturity and general fitness of the organism for marriage, but they
+remain after the disappearance of these. It is remarkable to notice how
+profound is the difference between the disharmonies of the reproductive
+functions in man and the perfect condition of adaptation of the same
+functions in the higher plants. In the case of the higher plants, as I
+described in my second chapter, the arrangements are complicated on
+account of the necessary mediation of insect life. Notwithstanding this,
+the perfection of the adaptation is remarkable. At the exact time when
+the reproductive products are ripe, the petals open and the nectar is
+secreted, while, in addition, at this time many flowers discharge odours
+agreeable to insects. Attracted by the scents and colours, the insects
+visit the flowers in quest of pollen or nectar, and, becoming dusted
+with pollen, carry it to the stigmas of the next flowers they visit. As
+soon as fertilisation has taken place the petals fade, the scents are no
+longer produced, and the insects cease to visit the flowers to which
+they are no longer necessary.
+
+It is not surprising that the disharmonies in the human reproductive
+apparatus are a frequent source of trouble. Little children, in whom
+sexual irritability has awakened prematurely, learn to satisfy it by
+means called “unnatural.” In many cases damage rapidly follows. “In the
+child,” wrote Dr. Christian, “there is no secretion of spermatozoa, and
+it is in the child that the results of onanism are most disastrous to
+the organism, and disastrous almost in inverse proportion to the
+age.[118] It is in early infancy that this aberration merits the evil
+reputation that it has acquired; it compromises health, intelligence,
+and even life. Quite young children wither, becoming pale, stupid, and
+fragile, when they have acquired this disastrous habit. The evil is
+almost entirely a consequence of the unripeness of the organism for
+sexuality.” Happily these evil occurrences are rare.
+
+A publication by Tissot, a Swiss doctor, on the subject of onanism, made
+a sensation in the eighteenth century. The book was full of
+exaggeration, and it was very inexact, but it contained interesting
+confessions from persons who had contracted the habit. A woman wrote to
+Tissot in the following terms: “But for the restraint of religion, I
+should have put an end to my life, which is ruined by my own fault.” Not
+infrequently the vice leads to melancholia.
+
+Other unfortunate results come from the ripening of the sexual products
+before the organism is ready for marriage, and before the character has
+been formed. As men cannot contract marriage before they are ready for
+it, irregular and frequently harmful sexual aberration may occur.
+
+The survival of this specific irritability until too late a period of
+life is another source of disaster. Old men who can neither excite
+passion nor satisfy it, often become victims of their own amorousness
+and unassuaged passions. It has been shown that passion may survive
+after the complete atrophy of the functions of the organs. Similarly it
+is the case that women from whom the ovaries have been removed, may
+continue to retain sexual irritability completely.
+
+Disharmony of sexuality may also occur between persons of different
+sexes. The fact that sexuality is usually more precocious in the male
+sex often produces a disharmony in the case of married persons. At the
+time when a woman is still in full possession of this specific
+irritability, the appetite in the man may be on the wane. From this
+disharmony there often follows conjugal infidelity or passion between
+persons of the same sex.
+
+Schopenhauer devoted attention to this subject and wrote as follows:
+“That nature herself may produce a condition totally opposed to the
+natural function offers a paradoxical problem of very deep
+interest.”[119] It is clear, however, when we consider the disharmonies
+in the development and activities of the functions in question, that the
+apparently paradoxical and strange aberrations of sexuality are natural
+enough.
+
+The existing disharmony gives rise to many evils from earliest youth to
+advanced age, and, consequently, it is not surprising to find that
+religions have denounced sexuality more or less severely. Dr. Christian
+expresses his astonishment “that in nearly all religions it has been
+considered a homage to the Deity to abstain from sexual
+intercourse.”[120] It is simply because the disharmonies of sexuality
+lead to sexual aberrations that religions have found cause for
+denouncing human nature as vile.[121]

+        and infanticide.—Disharmonies in the social instincts._
+
+As the functions of reproduction are seated deep in the organic world
+and none the less present cases of striking disharmony in mankind, it is
+not surprising to find similar want of adaptation in the family
+instincts of man, as these instincts have been acquired more recently
+and are less widespread in the living world.
+
+It has been shown that the animal world provides many examples of
+onanism and of aberrations of sexual congress. On the other hand, there
+are no cases in the animal world in which pregnancy is destroyed by
+aberrant instincts.
+
+To the human race belongs the distinction of having invented modes of
+sexual congress which are necessarily barren. No doubt the loss of the
+_os penis_ has made such occurrences more easy, as the presence of that
+bone would render interruption of coition more difficult. But there are
+many ways in which the spermatozoa may be prevented from accomplishing
+their function, and these are so common and so familiar that it is
+unnecessary to enumerate them. In civilised countries procreation is
+limited chiefly by such means. In its early days, the human race must
+have been distinguished by its unusual procreative capacity, but with
+the growth of civilisation many devices have been employed to limit
+that.
+
+Savages and races of low civilisation have recourse to artificial
+abortion rather than to means for preventing fertilisation, and abortion
+is almost universal among them.
+
+The great treatise of Ploss, “Das Weib,” to which I have made repeated
+reference, contains a whole chapter[122] on this subject. Deliberate
+abortion with the object of limiting the number of children is customary
+all over the globe. In most primitive races and among peoples of low
+civilisation it is practised openly without the smallest restraint. Many
+of these peoples have adopted the custom of limiting the family to two
+children by procuring abortion in subsequent pregnancies. The aborigines
+of Kaisar and of the islands of Watubela observe the rule strictly.
+Among the natives of the islands of Aaru it is rare to find more than
+three children in a family, because any others are destroyed by
+artificial abortion.
+
+A similar custom is widespread in India, being quite as common among the
+Hindoos who are ruled by England as among independent races. In the
+peninsula of Kutch, women frequently procure abortion, and one woman
+boasted to Macmurdo that she had made use of the practice five times.
+Abortion is equally common in Africa and America.
+
+Even in Europe there are nations amongst which abortion is permitted
+within certain limits. The Turks do not regard a fœtus as being really
+alive until after the fifth month, and have no scruple in causing its
+abortion. Even at later stages, when the operation becomes criminal, it
+is frequently practised. In 1872, at Constantinople, more than three
+thousand cases of abortion were brought before the Courts in a period of
+ten months. Under such circumstances it is not surprising that
+illegitimate children are rare in the East.
+
+Artificial abortion is not a modern invention, but was common in ancient
+times. The old Greeks practised it openly, without any legal restraint.
+Plato regarded it as within the province of the midwife, and Aristotle
+permitted it to married people when a pregnancy that was not desired
+took place.
+
+Steller, writing of the natives of Kamchatka of the eighteenth century,
+stated that among them marriage was contracted rather for sensual
+gratification than for the procreation of children, because they
+interfered with pregnancies by various kinds of medicaments and by
+violent operative interferences.
+
+The arts by which abortion has been produced are numerous and varied. In
+addition to the administration of drugs, chiefly of vegetable origin,
+implements have been employed. The natives of Greenland use the ribs of
+seals or of the walrus, and the Hawaians of the Sandwich Islands employ
+for the purpose a wooden implement fashioned as a deity.
+
+On the other hand, certain races have strongly opposed the practice of
+abortion. In the ancient world such races were the Medes, the Bactrians,
+the Persians, and Jews. Among the ancient Incas, abortion was a crime
+punished with death. Later on, the Christian nations followed this view.
+However, the reprobation of abortion occurs only in a comparatively
+small number of the nations of the earth, and even amongst these the
+practice is common in secret.
+
+Animals which are unable to procure abortion very often destroy their
+young, as I described in the second chapter of this volume. In the human
+race, infanticide is too common. The Greeks and Romans did not regard
+the newly born infants as possessing any right to live. The old Germans
+held themselves free to expose their infants. The Arabs, before the
+faith of Islam had spread to them, were in the habit of burying many
+female children alive. In India a similar custom is common, and in China
+it is notorious. According to figures collected by Eitel,[123] the
+Chinese of the province of Canton very often kill female children
+immediately after birth. “It may be said,” he wrote, “that the murder of
+female infants is the general rule among the Hak-lo, and especially
+among the Hak-ka of the agricultural classes. The Hak-ka themselves
+estimate the number of female children exposed as about two-thirds of
+those born.” In a little village in which the author lived for several
+years, an investigation, made with the help of some Christians, showed
+that without exception women who had given birth to two children had
+killed at least one of them.
+
+In Tahiti two-thirds of new-born children are killed, those of the
+female sex making up the greater part of the numbers. The first three
+infants and all twins are killed, and as a rule not more than two or at
+most three are actually reared.[124] Among the Melanesians the custom of
+infanticide is very common. “It must also be assumed,” said Ratzel,[125]
+“that in Ugi (Solomon Islands) all the infants are killed, to be
+replaced by the Bauros.”
+
+It is not surprising that such a widespread occurrence of artificial
+abortion and of infanticide among primitive races is bringing about a
+rapid diminution in the numbers of these, and may lead even to their
+extinction. This is taking place in the case of the natives of New South
+Wales, of New Guinea, and of the islands of Aaru. Nothing could show
+more plainly the feebleness of the human family instinct. In more highly
+civilised nations, the rude proceedings of savages have been replaced by
+clever devices to prevent conception, and infanticide has become rare.
+Artificial abortion is excited by modern methods suggested by the
+progress of science. The embryonic membranes are pierced not by the ribs
+of seals or hair-pins, but by sterilised sounds, and the operation is
+performed with strict asepsis. In averting the natural results of
+passion the woman is subjected to the smallest possible risk.
+
+It is indubitable that more than one race has perished because of its
+lack of the instinct of family. However, it need not be feared that the
+human race itself will disappear because of the failure of procreation.
+But it is plain that the readiness with which devices to prevent the
+production of children have been adopted shows the weakness of the
+family instinct in man, and opens up a problem to which the attention of
+moralists and legislators may well be directed.
+
+The family instinct is deeply seated, as it arose among animals more
+ancient than man; none the less it exhibits disturbances and aberrations
+in the human race capable of bringing about the extinction of peoples or
+nations. It is, however, strong enough to secure that man will persist
+in the future.
+
+Man certainly is a social animal, but the instinct impelling him towards
+union with his fellows is of recent origin. Such animal societies as are
+to be found among insects are not comparable with human associations.
+Among mammals, the nearest allies of man, the social instincts are
+developed only to a slight extent, and even the anthropoid apes show
+very little progress in this direction. Many of these creatures have
+shown in captivity the aptitude to become friendly with man or with
+other animals, and thus have displayed the beginnings of the capacity to
+form societies. But, in the wild condition, anthropoids live only in
+families, and these contain few individuals. As regards the social
+capacities of the chimpanzee Dr. Savage wrote:[126] “They cannot be
+called gregarious, seldom more than five, or ten at most, being found
+together. It has been said on good authority that they occasionally
+assemble in large numbers in gambols. My informant asserts that he saw
+once not less than fifty so engaged; hooting, screaming, and drumming
+with sticks on old logs, which is done in the latter case with equal
+facility by the four extremities.”
+
+We have little acquaintance with the social life of the anthropoids,
+but, so far as we know, these creatures present only the merest
+beginnings of the social instinct. Man has moved much beyond them in
+that direction. Even the lowest races and the most primitive of living
+peoples such as, for instance, the Bushmen or the aborigines of
+Australia, display a well-developed social instinct.[127]
+
+The universal presence of the social instinct among human beings would
+seem to afford the basis of a happy life. In the numerous attempts made
+to find a purely rational principle that may serve as the basis for
+morality without the intervention of supernatural sanction, abundant use
+has been made of man’s craving to live in association with his fellows.
+Those who have tried to deduce moral law from the essential constitution
+of man have relied largely upon the innate sympathy between man and his
+fellows. Such a line of argument is so common and has been employed so
+frequently that I need not spend much space in developing it. I shall
+limit myself to a few examples.
+
+Towards the end of last century Büchner,[128] a German physician,
+published a materialistic code of morality that made a considerable
+sensation. He wrote as follows on the question now before us: “What we
+term the moral sense arose from the social instincts and habits which,
+under pain of extinction, are developed in every society of men and
+animals. Morality depends on sociability, and varies with the peculiar
+conditions of each particular association. As man is essentially a
+social animal, and to be regarded, apart from society, merely as a wild
+beast, it is plain that the needs of the community must impose on him
+certain restrictions and directions that in time will pass into a
+settled code of morals.”
+
+Half a century later practically the same idea was repeated.
+Haeckel,[129] the well-known German naturalist, expressed it as follows
+in a volume that appeared a few years ago:—
+
+“Modern science shows that the feeling of duty does not rest on an
+illusory ‘categorical imperative,’ but on the solid ground of social
+instinct, as we find it in the case of all the social animals. It
+regards as the highest aim of all morality the re-establishment of a
+sound harmony between egoism and altruism, between self-love and the
+love of one’s neighbour.... If a man desire to have the advantage of
+living in an organised community he has to consult not only his own
+fortune but also that of the society and of the ‘neighbours’ who form
+the society. He must realise that its prosperity is his own prosperity,
+and that it cannot suffer without his own injury. This fundamental law
+of society is so simple and so inevitable that one cannot understand how
+it can be contradicted in theory or in practice; and yet that is done
+to-day and has been done for thousands of years.”
+
+The sexual and family instincts may be satisfied in many different ways,
+and this is also the case with the social instincts. Onanism and
+perverted passion may satisfy the sexual instinct; celibacy, artificial
+abortion and infanticide exist alongside the love of the wife and the
+parental cares. So also the social instinct of a criminal may be
+satisfied by his association with other criminals. It is well known that
+the most hardened criminals have their own codes, and they join
+faithfulness to their own companions to an atrocious attitude towards
+the rest of the world.
+
+It is not enough then merely to give scope to the social instincts that
+we all possess. We have to determine how far, and towards which of our
+fellow creatures, we are to exercise such instincts, and it is here that
+the difficulty arises which as yet has not been resolved by religion or
+rationalism. Must our social instincts reach to our relatives near or
+distant, or to our fellow townsmen, or compatriots, or to all white men,
+or to all men, white and black, or to the good only, or to the good and
+bad alike? Perhaps we should limit the operation of the instinct to
+those of our own religion, or who share our views of life? The
+instinctive feeling is quite silent on these points, and it is precisely
+on them that the difficulties arise. It is well known that at different
+epochs and in different circumstances very different answers have been
+given to such questions. When religion was predominant, a common faith
+was a bond transcending patriotism. Later on, patriotism itself became
+the dominant bond. In recent days, a conception of international
+solidarity began to appear. Thus, for instance, there was recently a
+combination of different nations against China, and nationality was
+forgotten. Some of the European nations banded themselves together and
+even assumed an Asiatic race in the union, with the object of punishing
+a common enemy. What was the bond that united nations so different? It
+was not religion, for the bond included Catholics and Protestants,
+orthodox Christians and Buddhists. Most probably the bond of union was a
+community of interest, the result of similar civilisation and military
+and political organisation.
+
+It has been suggested occasionally that the social instinct, or human
+sympathy, for the terms are practically identical, may stretch further
+and further and become so widespread that all the members of the human
+stock will unite and act only for the common good. But the problem is
+complex. Sympathy, when pushed too far, may become harmful. Nations have
+taken part in a campaign, impelled by some feeling of sympathy, and have
+brought harm on themselves. Sympathy extended to criminals and wicked
+persons is equally harmful. The social instinct itself must be regulated
+for the good of the community which it holds together.
+
+Ought we to extend our sympathy to all humanity, or to limit it to some
+particular section? Theorists have spoken of the solidarity of all
+humanity, believing it possible to extend our sympathy to the races
+furthest removed from us. In countries in which different races are
+brought in contact, very practical difficulties are encountered by the
+theorists. In America and in some other countries, for instance, laws
+have been passed against the Chinese, excluding the latter from the
+consideration granted to other races. The negro question also is very
+difficult in those countries in which the black race dwells amongst
+whites. In Europe it has been the custom to condemn the action of
+civilised races in taking their land from natives of primitive type.
+Sutherland, the author of a striking work on the origin and development
+of morality, justifies such arbitrary conduct. To the question, “Was it
+right for the whites to take possession of the Australian forests of the
+blacks?” he replied in the affirmative. “No doubt,” he said, “there is a
+moral instinct against it, but the action undoubtedly was right.”[130]
+In a summary of his conclusions he lays down that moral conduct is a
+compromise between the individual and social instincts that so often are
+opposed. But he has no more to say than his predecessors as to the
+rational basis of the compromise.
+
+The social instinct has been acquired by mankind too recently, and it is
+still too feeble, to be a trustworthy guide in all conduct. To obviate
+this difficulty, at many different times, divine sanction has been
+evoked to control the relations among men. The categorical law has been
+formulated with the same object. Thus by one means or another, some kind
+of social order has been kept up. The efficacy of these additional
+guides is seen clearly on those rare occasions when some special
+combination of circumstances has set people free from them. Thus at
+Moscow, in 1812, before the arrival of the French army restored
+authority, and lately, after the eruption in Martinique, the ordinary
+authority lapsed, the anti-social instincts of the people were loose,
+and a clear idea was given of the inherent weakness of the human social
+instinct.
+
+I have shown that in man the instinct for choosing food and the sexual
+and social instincts are still so weak that it is impossible to trust to
+them in the absence of other guidance. It is as equally necessary to
+determine what kind of food is most suitable for men in different
+conditions of life, and what means are best fitted to satisfy rationally
+his sexual and family instincts. So also it is urgent to determine
+exactly the direction and object of the social instinct. For the love of
+our fellow creatures we should seek the best ways of making them happy.
+
+But what is happiness? Is it the feeling of well-being experienced by
+the individual himself, or is it the judgment of others on his
+sensations? It is notoriously difficult to pronounce on the happiness of
+another. From the outside, when a man seems to enjoy health, to have a
+family and comfortable means of subsistence, we are inclined to call him
+happy; but the individual himself may have a very different opinion
+about himself. It is often impossible to rely on the judgment of others.
+On the other hand, the opinion of an individual himself on his own
+condition may be equally fallacious. Very often the feeling of
+well-being is a symptom of general paralysis, as may be inferred from
+the following quotation: “The patient is well pleased with himself, and
+delighted with his constitution and circumstances. He boasts without
+ceasing of his robust health, his muscular strength, the clearness of
+his complexion and of his general ‘fitness.’ His clothing is magnificent
+and his residence palatial. In a more advanced stage of the disease, the
+exaggeration becomes extreme. He believes that he is able to blow down
+the walls with his breath, or that he could carry a ton, or drink a
+hogshead of wine, or that nothing could tire him out. Then megalomania
+begins, and the patients believe themselves in possession of titles, of
+power, and wealth. They are members of parliament, noblemen, princes,
+generals, kings, emperors, and popes, or God Himself.”[131]
+
+As general paralysis is a result of syphilis, in order to make a large
+number of persons believe themselves thoroughly happy, it would be
+necessary only to spread this disease. Without lingering on this
+paradox, I may at least point out that the problem of happiness, which
+is associated intimately with social life, is extremely difficult.
+
+The social instinct is equally powerless to solve the problem of justice
+in its relation to the general interest of humanity. It is plain enough
+that, in the existing condition of human knowledge, we all inflict and
+undergo injustices of different degrees. This misfortune is a
+consequence of the disharmony of human nature.
+
+From what I have already said, it must be clear that before we can find
+a rational guide to direct us in the operation of our social instinct,
+we should have to determine exactly the nature of true happiness for the
+individual and of true justice. Then only should we be in a position to
+set about making human life as happy as is possible.

+           DISHARMONIES IN THE INSTINCT OF SELF-PRESERVATION
+
+
+  The instinct of self-preservation in animals—Man’s instinctive love of
+  life—Indifference to life during childhood—Buddhist legend on
+  instinctive self-preservation and the fear of death—Fear of death
+  treated in literature—Confessions of Tolstoi regarding the fear of
+  death—Other opinions on the subject—The fear of death an instinctive
+  phenomenon—Development in man of a love of life—Treatment of the

+  between the love of life and the conditions of human existence—The
+  part played by the fear of death in religions and systems of
+  philosophy
+
+
+It is not to be wondered at that man’s social instinct exhibits so many
+imperfections and disharmonies, seeing that it is still in an unsettled
+condition, and is a recent acquisition. On the other hand, we should
+expect to find that love of life and the instinct of self-preservation
+had reached a high degree of harmony, since these have been in process
+of development throughout the whole animal series that culminated in
+man. Even in the lowest forms of life many contrivances exist for
+purposes of protection. Creatures, the bodies of which are merely
+microscopic drops of protoplasm, the living material, may be protected
+by shells from external influences which threaten their destruction.
+Plants protect themselves, sometimes by means of thorns which prevent
+them from being eaten, sometimes by secretions either merely irritant in
+character or actually poisonous. Among animals the means employed for
+self-preservation are even more numerous. Shields and shells, the
+secretion of fluids exhaling unpleasant odours, or facilitating escape
+by clouding the water, as in the case of the ink of the cuttlefish,
+offensive weapons, strong teeth, and many other characters, serve no
+other purpose than to protect the individual life. The exposition of
+this subject would involve writing a complete treatise on the
+comparative anatomy of plants and animals.
+
+Among lower animals the preservation of life is accomplished without
+mental connivance, conscious or unconscious. Soon, however, protective
+instincts begin to appear. Simple cases of these are flight at the
+approach of danger, protection by a covering of slimy froth secreted by
+the creatures themselves, or built up from this excreta, or from foreign
+matter. Such facts show that the love of life and the instinct of
+self-preservation are almost universal in the living world.
+
+All these devices for the avoidance of danger and escape from death
+could have been developed in animals before these had any distinct idea
+as to what death was. We know that some animals can distinguish between
+living and dead prey. Some carnivora recognise the smell of dead bodies.
+Those which are accustomed to feed on living creatures refuse all
+others, detecting the difference by the absence of movement. As in such
+cases the idea of death is imperfect, it is easy to deceive the
+creatures by offering carcases artificially set in motion, or living
+prey rendered motionless by some means or other. In order to escape from
+enemies so readily imposed upon, many insects when alarmed become
+motionless and feign death; and that may be regarded as yet another
+instance in the category of natural means for the protection of
+individual life.
+
+Moreover, the higher animals, such as mammals, exhibit a profound
+ignorance of death, many of them remaining completely undisturbed in the
+presence of dead companions, or even devouring the latter at the risk of
+contracting a fatal disease. Rats, for instance, eat the bodies of rats
+which have died of plague, and while appeasing their hunger themselves
+contract the disease which they transmit to other animals, particularly
+to human beings. Unlike those animals, however, which are indifferent to
+the death of their kind, there are others that instinctively shrink at
+seeing the dead bodies of their own species. Horses on passing a dead
+horse show signs of discomfort, and attempt to run away. Bullocks when
+witnessing the slaughter of others also exhibit evidences of distress
+and fear. In spite of these examples, however, it is quite certain that
+animals, even those highest in the scale of life, are unconscious of the
+inevitability of death, and of the ultimate fate of all living things.
+This knowledge is a human acquisition.
+
+In man, the instinct of self-preservation is well developed. Hardly
+appreciable during infancy, it manifests itself in a marked degree in
+young children. At the sight of a human corpse, children become
+panic-stricken, as though confronted by a wild beast or snake.
+
+In young adults this instinct of self-preservation, which is closely
+connected with an instinctive fear of death, is not fully developed. It
+often takes some special circumstance to awaken it, such as a dangerous
+illness, an accident, or the perils of war. Young people who while in
+good health believe their lives to be in danger, often take it to heart
+so as to make themselves really ill. Relating his impressions during the
+siege of Sebastopol, Tolstoi, who at that time was only twenty-six years
+of age, writes as follows: “Notwithstanding the distractions offered by
+various and urgent duties, the instinct of self-preservation, and the
+longing to quit this horrible place of death was present in the hearts
+of all. This desire was equally strong in all; in those mortally
+wounded, and in the volunteer rushing with all his might into the centre
+of the fray to open a path for the horse of the general, in the general
+himself as he directed and controlled his men. The officer of marines,
+in the middle of a battalion in action, crushed so that he could hardly
+breathe, felt it equally with the wounded man carried on a stretcher by
+four soldiers until, further progress being impossible, he had been set
+down just under the Nicolai battery, or the artilleryman who had served
+his gun for sixteen years.” In the normal course of life, however, the
+young do not show an instinctive clinging to life in any marked degree.
+They often risk their lives for trifling reasons, and commit all sorts
+of indiscretions hurtful to life or health without a thought of the
+consequences. They may be inspired by the highest motives, but they are
+equally ready to fritter strength away in the gratification of the
+lowest appetites. Youth is the age of disinterested sacrifice, but also
+of indulgence in all kinds of excesses, alcoholic, sexual and others.
+Youths seem to think that they will always attach the same value to
+life, and that between death at thirty years of age and death at sixty,
+there is a difference only of time. As their love of life is
+indifferently developed, young people are often extremely exacting, the
+pleasure they enjoy being but moderate, whilst the suffering provoked in
+them by the slightest annoyance is intense. They consequently become
+epicureans in the lowest sense of the word, or else abandon themselves
+to exaggerated pessimism.
+
+“Edite, bibite, post mortem nulla voluptas” was the motto of German
+students, greedy for pleasure, and unknowing that a love of life
+develops with age in every human being. On the other hand, in order to
+keep the balance between joy and sorrow, youth, true to its instincts,
+undervalues the former and exaggerates the latter, thus arriving at a
+pessimistic view of life, and declaring that existence is a misfortune
+in itself. It is significant that Schopenhauer published his theory of
+pessimism at the age of thirty-one. His successor, R. Hartmann, when
+twenty-six years old, proclaimed that human existence is an evil which
+one should get rid of at all costs. Optimistic theories, on the other
+hand, have been set forth either by persons advanced in years or by
+persons whom special circumstances have caused to appreciate the joy of
+living. As a counterbalance to the pessimism of German philosophers,
+Duhring formulated a theory of optimism in his book “Der Wert des
+Lebens,” but was himself blind at the time. Sir John Lubbock published
+some years ago a book entitled “The Pleasures of Life,” which opens with
+the following sentence: “Life is a great gift.” His attitude towards
+life is entirely opposed to that of the pessimists, but then he
+formulated it at the age of fifty-three.
+
+It has long been recognised that the old attach a higher value to life
+than do the young. J. J. Rousseau, for instance, says: “Life becomes
+dearer to us as its joys pass away. The old cling to it more closely
+than the young.”[132]
+
+This reflection is absolutely correct, and is proved by a number of
+facts. I once knew very intimately a scientific man who had passed a
+very unhappy youth. Being hypersensitive to pain, he tried to assuage it
+by every means in his power. Some trifling annoyance sufficing to throw
+him into a state of utter prostration, he was in the habit of resorting
+to the aid of narcotics. In order to escape from mental anguish he
+inoculated himself with poisons. By the time he had arrived at an
+advanced age his hypersensitiveness gave place to feelings much less
+acute. He ceased to resent the ills of life so bitterly as he did in his
+youth; while he came to appreciate better the positive side of life, and
+even in moments of unhappiness he did not contemplate putting an end to
+his existence.
+
+In youth he was pessimistic, and insisted upon the preponderance of evil
+over good. As he became older, his attitude towards existence became
+entirely modified.
+
+I do not say, however, that it is necessary to be old in order to
+realise the misfortune of death. “He who pretends to face death without
+fear is a liar,” said J. J. Rousseau. “That all men fear to die is the
+great law dominating the thinking world, and without which all living
+things would soon cease to exist. This fear is a natural impulse, and is
+not merely an accident but an important factor in the whole order of
+things.”[133]
+
+One often hears people express their indifference to death, but an
+examination into their real feelings on the subject soon shows the true
+state of affairs. I once happened to be present when a lady, already
+well advanced in years, expressed a wish for death, and said that she
+had no fear of it whatever. On acquiring a fuller knowledge of her case,
+I recognised that she was seriously ill, and that she regarded death as
+the only possible termination to her sufferings. As soon as she found
+that recovery was possible, she manifested intense delight at the
+prospect of a prolonged life freed from incessant pain.
+
+Instinctive love of life, and fear of death, which is only a
+manifestation of the former, are of an importance in the study of human
+nature impossible to over-estimate; it is therefore necessary to
+consider a few instances throwing light upon the subject. Even the
+ancients were interested in the problem. The subject is perhaps as well
+dealt with in a Buddhist legend as anywhere.[134] “The young Prince
+Çakya-Mouni, the founder of the Buddhist faith, being desirous of
+discovering the true meaning of life, expressed a wish to leave the
+world and devote himself to a religious life. In order to turn him from
+his purpose, his father built him a magnificent palace, wherein he could
+indulge in every sort of pleasure, and in which he would be protected
+from all sorrow. Under this system he never saw old people, nor those
+who were diseased, nor the dead. In spite of being thus strictly
+guarded, the young prince often contrived to escape into the outer world
+in order to drive about. During his first drive, he met a broken-down,
+decrepid old man, with varicose veins, decayed teeth, a wrinkled skin,
+and grey hair, bent double with age like the roof of a house, leaning
+upon a stick; all traces of youth had departed from him, only
+inarticulate words came from his throat, his procumbent body resting on
+the stick, and his limbs and every part of them trembling.” Having
+learnt from his coachman that this was an old man, and that “in all
+living creatures age creeps upon youth,” that every one came to it and
+that “there was no way out of it,” the prince was so deeply impressed
+that he said to his coachman, “What a misfortune to be a weak foolish
+person, whose intelligence, blinded by the pride of youth, sees nothing
+of old age. Turn round my chariot. I would return. What are games and
+pleasures to me whose body is the future dwelling-place of old age?”
+Another time Çakya-Mouni met on the road a man consumed by fever, his
+body weakened, his breathing difficult. Informed by his coachman that
+the man was suffering from disease, the young prince exclaimed; “Health,
+then, is a mere dream, and the fear of disease takes a terrible form.
+What wise man, having seen such a phase of human existence, could
+continue to be gay and happy?” Shortly after Çakya-Mouni went out for
+the third time, and “saw a dead man placed on a bier covered by a pall,
+surrounded by his relations, all weeping, lamenting, wailing, their hair
+disordered, placing dust upon their heads, and beating their breasts.”
+The violent emotion produced by the sight of the dead man caused the
+prince to say to himself: “Woe to youth threatened with old age! Woe to
+health, the prey of every kind of disease! Woe to the life of man which
+lasts but a little while! Woe to the attractions of pleasure which
+seduce the hearts of the wise.” These reflections of Çakya-Mouni are the
+basis upon which Buddhism is founded, and that religious philosophy is
+impregnated with pessimistic doctrines relating to human life.
+
+Modern pessimists hold views resembling Buddhism. Schopenhauer from
+early youth was engrossed by the great problems of human life. His
+mother, in a letter to him[135] reproached him with “grumbling at the
+inevitable,” which shows that at twenty-seven years of age he had
+revolted against the idea of death. The problem of mortality was one of
+those in which he was most deeply interested, and his fear of disease
+and death was such that he left Berlin at the first outbreak of cholera
+in 1831 (influenced by the death of Hegel, who succumbed to the
+disease), and went to live at Frankfort, a town unvisited by the
+epidemic. He affirms[136] that “the greatest, and generally speaking the
+worst, misfortune that can befall any one is to die, and there is no
+fear equal to the fear of death.” It was the impossibility of escape
+that suggested to him the idea of a pessimistic philosophy.
+
+The literatures as well as the philosophies of all periods have
+dealt with the problem of death. Edmond de Goncourt tells in his
+“Journal” how, in conversation with his friends, this question was
+always recurring. The following is an account of one of these
+conversations:[137] “Our old established dinner of five took place
+to-day. Flaubert was missing, so there were only Tourguéneff, Zola,
+Daudet, and me. The ethical ennui of some of us, the physical
+sufferings of the others, led the conversation to death, which we
+discussed until eleven o’clock, sometimes passing to other subjects,
+but always coming back to the gloomy topic. Daudet declared that in
+his case it was an obsession, _a poisoning of his life_, and that he
+never moved into a new house without looking round for the place
+where his coffin would come to lie. Zola told us that his mother had
+died at Médan, and that, as the staircase proved too narrow, the
+coffin had had to be lowered from a window; he declared that he
+never looked at that window without wondering who would be taken out
+that way next, he or his wife. “Yes,” he said, “ever since that day
+death has always been in the background of our thoughts, and very
+often during the night, looking at my sleepless wife, I feel that
+like me she is thinking of it, and we lie quietly without saying
+aloud what is in our minds—for shame, yes, for very shame—_Oh! it is
+terrible, that thought—and the terror of it becomes visible!_ There
+have been nights when I have leapt suddenly out of bed, and held
+myself for a second or two in a state of abject terror.”
+
+Jean Finot[138] was told in confidence by E. de Goncourt that if he
+could banish the thought of death from his mind life would be relieved
+of an almost intolerable burden. Jean Finot also relates that in the
+course of a memorable evening spent with Victor Hugo at the house of the
+latter, nearly all of the distinguished persons who were present, when
+questioned as to their ideas on the subject of death, frankly admitted
+that the thought of it inspired them with fear and sadness. Amongst
+modern authors Count Léon Tolstoi has dealt most with the problem of
+death. In many of his works whole pages of memorable reflections on the
+subject are to be found, but the most harrowing and terrible picture he
+ever painted is contained in his “Confessions.”[139] The reader will
+pardon my propensity for quoting passages relating to death. He will
+recall the account of the Siege of Sebastopol already quoted by me, in
+which every one was described as fearing death when faced by danger; but
+this fear, as the author was a young man of twenty-six, was not wholly
+absorbing.
+
+Shortly before he attained his fiftieth year, Tolstoi became bitterly
+tormented by the thought of death. He describes the beginning of this
+mental crisis in the following words: “First there came moments of
+perplexity, of arrest of vital force, as though I had lost the power of
+living and moving; I felt utterly lost, and fell into a state of
+complete dejection. This passed away, however, and I continued to live
+on as before. Before long the moments of perplexity became more
+frequent; the arrest of my living energies was always manifested by a
+renewal of the same questions, ‘Why? and What comes after?’”[140] For
+some time Tolstoi did not pay much attention to his mental condition,
+but by degrees he began to analyse it, and reached the following
+conclusion: “The fact is that life is a blind alley. I had lived, worked
+and marched onward, and had arrived at the edge of an abyss, and nothing
+remained to me but to fall into it. And yet I could neither stop nor
+retrace my footsteps, nor shut my eyes in order not to see suffering and
+inevitable death. It was a void, a complete annihilation.”[141] “In this
+condition I felt that I must cease to live, and, fearing death, I had to
+employ various ruses to prevent myself from taking my life.”[142] “I
+could attach no reasonable meaning to any action of my life. I was
+merely astonished to think I had failed to realise the position from the
+beginning. All that, I said to myself, must have been patent to all the
+world long ago. If not to-day, then to-morrow, disease and death—they
+are already here—will attack elderly persons—me—and there will remain
+only corruption and worms. My deeds, whatever they may be, will be
+forgotten sooner or later, and I shall be no more. Why then take pains
+about anything? How a man can know all this and yet go on living amazes
+me. One can only go on living just so long as one is intoxicated with
+life; once sober, however, one cannot fail to see what an idiotic fraud
+it all is. It is also true that there is nothing even amusing or
+intelligent about it; it is simply stupid and cruel and nothing more.”
+Seeing no way out of this, Tolstoi turned his reflections on family
+love: “My family ... I say to myself ... but then my family, my wife,
+and children are also merely human beings! They live under the same
+conditions as I myself. They have the choice between living a lie or
+facing the horrible truth. Why then should they live at all? Why should
+I love, cherish, and protect them? In order that they may experience the
+same despair, or that they may go through life like idiots? Loving them,
+I cannot conceal the truth from them; every step forward in knowledge
+leads to this truth; and the truth is death.”[143] To conclude this
+series of quotations, which must have given the reader some idea of the
+love of life and the fear of death, I shall give one more example,
+taken, not from the pen of a master but from daily life.[144] It refers
+to the death in the Christian community of a “minister of God, who was
+pious as a S. Francis of Assisi, candid as a young girl, of a rigid
+asceticism, and renowned for his charity.” Logically speaking, the death
+of such a man should have been peaceful. Had he been a fictitious
+character, his author would not have described his death except in the
+conventional fashion. This is what really occurred, according to the
+letters of an intimate friend of the dying man, who wrote as follows:
+“Our poor friend is fighting death inch by inch in a way that is
+positively tragic. He who was so full of resignation, so serene, so
+perfectly at peace with his own soul, _is terrified by the approach of
+death_. It is a _horrible sight_, that moves one to tears. We are
+powerless not only to afford him physical relief but to console the
+terrible anguish which assails the clear intellect that clings so
+desperately to life, and which death will claim while fully alive. ‘I
+could still,’ he cried, ‘give a course of lectures on theology or
+political economy, and I must die.... It is terrible to be fully
+conscious.... How much better it would be if I could not think!... And
+what is it that we ask of God? Eternal happiness! It is just as if one
+of your workpeople came and asked you for a thousand francs for a day’s
+work!’ You would answer him, ‘What nonsense you talk, you must be mad,
+my friend!’ _It is hard to die._ I confess to you, my friend, that this
+makes one reconsider religion and philosophy.... The goodness of God is
+not what we think ... _there is a mystery over us_.... Is death then
+truly the King of Terrors for those who have led good lives?”
+
+What is this love of life which makes death so terrible? It is a very
+interesting question, and Tolstoi himself has published an essay on “the
+fear of death.”[145]
+
+He tries to prove that the feeling arises from a false conception of
+life. “Those who fear death,” he says, “fear it because it seems an
+empty darkness, but the darkness and emptiness present themselves merely
+because they have a false conception of life.”[146] According to Tolstoi
+man should have no greater fear of death than of any of the other
+changes to which it is subjected by life. “No one is afraid of falling
+asleep,” he says, “and yet the phenomena of sleep are like those of
+death—there is the same loss of consciousness. Man does not fear sleep,
+although the arrest of consciousness is as complete as in death.”[147]
+
+Tolstoi thinks that the fear of death is a superstition, and that it
+disappears when we see life as it is.[148]
+
+Tokarsky,[149] another Russian writer, a few years ago published a
+treatise on the fear of death, and tried to show how little reason there
+was for it. The writer was a physician for the insane, and knew himself
+to be afflicted with an incurable and fatal disease. His observations on
+the fear of death were probably based on his own feelings. Judging from
+the evidence of a number of persons who had been in mortal danger,
+Tokarsky declared that death had no terror, and that it was unnecessary
+to fear it.
+
+Tokarsky’s theory was supported in recent years by Finot[150] whose
+arguments in its favour were similar to those of his predecessor. He
+held that man himself created the fear of death, and that the prospect
+of an unknown future played a considerable part in it. “Beyond that
+which we see,” says Finot, “there is always something that we cannot
+see, and it is the invisible that we fear.”[151] The idea that death is
+generally attended by pain seems to Finot quite erroneous, and he comes
+to the conclusion that “our ignorances and prejudices are responsible
+for the creation of this superstition, so terrible to contemplate, so
+far removed from the truth.”[152] Instances which have occurred of
+people threatened with death and suddenly restored to life, give proofs,
+according to Finot, that death, far from being painful, is attended by
+pleasant sensations. With regard to this, Heim, a Swiss savant, says
+that tourists who have had serious falls while mountaineering, and have
+been so near to death that they experienced all the premonitory
+symptoms, felt above all a sensation of ecstasy.
+
+It cannot be denied that some forms of death are pleasant, but it is no
+less certain that in many other cases, and these too the majority—the
+sensation of approaching death is, on the contrary, extremely painful.
+This question, however, is not necessarily connected with the fear of
+death that may come to those who are not yet about to die. But it is
+precisely the latter mode of fear that is so important a factor in human
+life. Men who are dying of starvation do not feel painfully hungry at
+the moment of death. The actual pain of hunger lasts only for a limited
+period, probably, in the case of man, only about twenty hours, after
+which it is succeeded by a condition of lassitude and general weakness,
+which however is different from painful hunger. The fear of death is
+similar, for in certain cases it does not last up to the end of life.
+The pain of thirst, on the other hand, is much more persistent, lasting
+up to the end.
+
+Finot discussed the instinctiveness of the fear of death. “The
+question,” he wrote, “is important. For if the fear be instinctive, it
+is independent of our will and not to be controlled by reason. It would
+then break out in every case at the approach of death. Now the evidence
+of many persons who have no more than escaped mortal danger is clearly
+against the view.”[153] Hunger is certainly instinctive, and yet is not
+always felt when the body is exhausted by want of food or menaced by
+death from starvation.
+
+Closer investigation leaves no doubt but that the fear of death is truly
+an instinct. In some of the higher animals it exhibits itself in the
+same fashion as other instincts. The intimate friend, whom I have
+already mentioned, was for years in constant expectation of death, and
+faced its approach with perfect calmness. Believing that he had played
+his part in life to the best of his power, not only did he think it
+quite natural that he should cease to live, but he regarded the
+possibility of a decrepid and painful old age with the greatest possible
+repugnance. In his case, neither reason nor desire led to a fear of
+death. When, however, it was definitely diagnosed that he suffered from
+a disease which might prove fatal, there was aroused in him a certain
+sensation which must have been the fear of death. Analysis of Tolstoi’s
+statements in his “Confessions” makes it clear that his sensations on
+reflecting that he too would cease to be, and that there would be left
+only corruption and worms, were no other than the instinctive fear of
+death, a fear that his reason was powerless to control. To follow
+Tolstoi in telling any one that the fear of death is a form of
+superstition which must be subdued by the intelligence, is no better
+than to attempt to console a woman about to undergo ovariotomy by
+telling her that as in future she will be unable to bear children she
+ought to subdue her sexual instincts. She will find out that her desire
+is not under control of the will but is a pure instinct.
+
+The fear of death has long been recognised as an instinct.
+Schopenhauer,[154] for instance, interpreted it in that way. According
+to him, “from the point of view of intelligence there is no ground for
+fearing death. Reason, which is the outcome of knowledge, does not
+present death to us as an evil. It is certainly not the rational,
+conscious part of ourselves which fears death; the _fuga mortis_ which
+pervades all living beings is an emanation of the blind will.” This
+“blind will” is no other than a pure instinct which is independent of
+our rational will.
+
+I need not pursue the subject, but I may recall that Lord Byron came to
+the conclusion that the fear of death is an instinctive manifestation of
+the soul. In “Cain” he expressed this view sufficiently clearly:—
+
+                                     I live,
+           But live to die; and living, see nothing
+           To make death hateful, save an _innate clinging_,
+           A loathsome, and yet all _invincible_
+           _Instinct of life_, which I abhor, as I
+           Despise myself, yet cannot overcome—
+           And so I live.
+
+Later on in the same poem Byron makes Cain say of his father Adam:—
+
+                                    Ere he plucked
+                The knowledge, he was ignorant of death.
+                Alas, I scarcely now know what it is;
+                And yet I fear it, fear I know not what.
+
+It is then indubitable that among the instincts of man there is one
+which loves life and fears death. This instinct develops slowly and
+progressively with age. In that respect it is astonishingly different
+from other instincts. When hunger or thirst or sexual desire is
+gratified a sensation of satisfaction is experienced, and this readily
+passes into satiety or even indifference. The mood lasts for a certain
+time, and then the instinctive needs reawaken. The instinct of life,
+however, behaves very differently. In most human beings it develops
+slowly and becomes stronger and stronger as the years pass by. In
+childhood and early youth we are very anxious to “grow up,” but when we
+are adult we have no desire to grow old. We are greatly disturbed by the
+appearance of wrinkles and grey hair. Instead of being glad to have
+finished a great part of our mortal career, we feel sad at being nearer
+the inevitable end. Old age, as it usually presents itself, is marked by
+ugly features, and often by repugnant or even horrible characters.
+Little children are usually terrified by the appearance of very old
+persons, and it is a familiar nursery threat to send for an old man.
+
+The murder of the aged is a custom widespread amongst the lower races.
+The natives of Fiji bury their old men alive, on the pretext that they
+have become utterly useless. The custom is in existence throughout
+Melanesia, and occurs in New Caledonia and in most of the adjacent
+Polynesian islands. Old age is universally despised in that part of the
+world. The natives of Australia respect old people so long as they
+retain their activity, but once they become unable to take care of
+themselves they are abandoned. Often they are killed and eaten, and this
+custom is favoured by their religious beliefs.[155] The ancient
+inhabitants of Germany, according to the investigations of Grimm,
+“killed the old and the sick, and often buried them alive.”
+
+The modern civilised world has certainly made considerable progress. The
+old are no longer killed; they are tolerated, and accorded liberty to
+commit suicide. In many countries work is often refused to the old on
+the plea that they are not strong enough for it, and at the same time
+they are refused admission to almshouses on the pretext that they are
+not yet old enough. Dealing with the question of the average life and of
+the normal life, Paul Bert[156] expressed himself with regard to the
+aged as follows: “They deserve congratulations, care and consideration,
+_but the prolongation of their lives does not demand any special
+solicitude from society_.”
+
+However, in spite of the characters of old age which make it horrible
+and useless, and at best no more than to be tolerated, and in spite of
+the physical and intellectual weakness that accompany it, the
+instinctive love of life is preserved in the aged in its strongest form.
+To make quite certain about this I have visited almshouses for the aged,
+and it was easy to see that all the inmates hoped that their days might
+be prolonged. In a Home occupied by fairly well-educated persons, I
+discovered that one and all felt as if they were continually being
+threatened by death, as if they were convicts awaiting the day of
+execution. At the Salpêtrière, where there are a number of very old
+women, septuagenarians are regarded almost as young girls. The great
+ambition of women of eighty is to live to one hundred, and the desire to
+live is almost universal.
+
+This seems a contradiction of another fact demonstrated by statistics,
+that age increases the frequency of suicide. It is certain that more old
+men commit suicide than young men, but on careful inquiry into the
+statistics of the subject, it becomes evident that the chief incentive
+to suicide does not lie in the cessation of the will to live, but in the
+difficulties experienced by old people of earning a living, and in the
+frequent presence of disease in the aged. Deprived of the means of
+existence, refused the shelter of charitable institutions, old men are
+apt to fall back upon a rope or the fumes of charcoal. Statistics
+relating to the suicide of the aged show that the greatest number of
+victims belong to the poorer classes. The suicide of rich old men is
+generally prompted by the presence of incurable disease. There is,
+however, need for much wider inquiry into the subject. It would be
+interesting, for instance, to obtain more detailed information regarding
+the motives which urge the old to put an end to themselves. In recent
+times the suicide of Max von Pettenkofer aroused public attention. After
+a distinguished scientific career, he resigned his post of Professor at
+the University of Munich at the age of seventy-six. He went to live a
+little way outside the town on a property where he devoted himself to
+gardening and other country pursuits. Although a sufferer from diabetes,
+his intellect remained unimpaired, but he became a prey to extreme
+melancholy, owing to the death of some friends to whom he was greatly
+attached. Moreover, during the latter part of his life he suffered from
+a septic affection of the neck. This disease, not fatal in itself, was
+the indirect cause of Pettenkofer’s death, which occurred by suicide at
+the age of eighty-three. The _post-mortem_ examination[157] showed a
+fairly well preserved organic system, healthy, with the exception of
+chronic inflammation of the membranes of the brain and atheroma of the
+cerebral arteries. The circumstances relating to this particular case of
+suicide are unusually well known, and yet there are many obscure points
+about it which are of the highest importance. The chronic meningitis
+from which the aged scientist suffered conclusively precluded the theory
+that the motives which led him to commit suicide were prompted by the
+phenomena of normal life. On the other hand, instances are not wanting
+of old men of good education and refined surroundings who cling
+tenaciously to life, even at a much more advanced age than the Munich
+professor.
+
+The instinctive love of life resembles the sexual instinct in a great
+many women. Just as the love of life goes on increasing when the best of
+life is past, sexual pleasure is often unfelt by women until their
+beauty is already faded.
+
+Another character common to the love of life and the sexual instinct is
+that they both persist throughout old age, although they can no longer
+be satisfied.
+
+Edmond de Goncourt relates in his diary that at his réunions of literary
+celebrities (Zola, Daudet, and Tourgéneff), the conversation turned most
+frequently upon the subjects of love, life and women. “Death or love,
+strangely enough,” says Edmond de Goncourt, “are always what we talk
+about after dinner.”[158] Old age was even then knocking at the doors of
+the distinguished writers mentioned, and so it is quite natural that
+their interest should have been wholly absorbed by the two instincts
+which exhibit such enigmatic and paradoxical tenacity.
+
+We saw in the preceding chapter how disharmonious is the sexual instinct
+which often only develops at, and nearly always persists until, a period
+of life when its normal and regular functional activity is no longer
+possible. We saw, too, the ill resulting from this disharmony in the
+reproductive apparatus. The ill, however, although serious, only amounts
+in that case to an inconvenience which can be endured.
+
+Far worse is the disharmony of the instinctive love of life which
+manifests itself when death is felt to be near at hand. It is then
+incomprehensible and particularly terrible, and humanity, from time
+immemorial, has sought the key to the tragic puzzle, and tried by all
+the means in its power to unravel the mystery. The religions of all
+times have been concerned with the problem. “Religion,” says Guyau,[159]
+“consists for the most part of meditation upon death. If we had not to
+die there would probably be still more superstitions among men, but
+there would probably be no systematised superstitions nor religions.”
+Philosophy also has tried to solve the question of death. Some ancient
+philosophers held the opinion that philosophy is only a meditation upon
+death. Socrates and Cicero[160] have well said that “the life of a
+philosopher is a continual meditation upon death.” In our own day
+Schopenhauer developed the same theory. “Death,” he said,[161] “is the
+real inspiring genius of philosophy.... Without death it is doubtful if
+philosophy would exist at all. It is therefore quite natural that a
+special essay on Death should preface the last, the most serious, and
+the most important of my books.”
+
+Judging from the facts set forth in the last three chapters, there can
+be no doubt but that the human constitution, although in many ways
+perfect and sublime, exhibits numerous and serious disharmonies, which
+are the source of all our troubles. Not being so well adapted to the
+conditions of life as orchids are, for example, in the matter of their
+fertilisation by the mediation of insects, or the burrowing wasps for
+the protection of their young, humanity resembles rather those insects
+the instinct of which guides them towards the flame which burns their
+wings.
+
+Even at a time when humanity had attained no definite knowledge of
+itself, a vague suspicion prevailed as to the existence of disharmonies,
+and an effort was made to remedy the evil. The following chapters will
+show what man has done with a view to remedying the natural disharmonies
+of his constitution.

+ RELIGIOUS ATTEMPTS TO COMBAT THE ILLS ARISING FROM THE DISHARMONIES OF
+                         THE HUMAN CONSTITUTION
+
+
+  Animism as the foundation of primitive religions—The Jewish religion
+  in relation to the doctrine of immortality of the soul—The religions
+  of China—Ancestor-worship in Confucianism—The conception of
+  immortality in Taoism—The persistence of the soul in the Buddhist
+  religion—The paradise of the Chinese Buddhists—Ancestors worshipped as

+  the tissues and cells of the body—Religious hygiene—Religious means of
+  controlling the reproductive functions and of preventing
+  diseases—Failure of religions in their attempts to combat the ills
+  arising from the disharmonies of the human constitution
+
+
+Humanity did not await the discovery by science of the existence of
+disharmonies before trying to find remedies for them. The will to live,
+to preserve health, to satisfy the instincts and to make them act in
+unison, have driven mankind, in the very earliest days of reflection, to
+invent remedies for the imperfection of the human constitution.
+
+I have shown that, even in the case of animals, the instinct as to
+choice of food does not save them from certain harmful substances. Man
+himself has for long recognised that this instinct of his is no safe
+guide, and has tried to discover surer methods of distinguishing between
+substances that are useful as foods and substances that may cause
+disease or death. The best wisdom of primitive man must have been given
+to the observation of the effects of substances which had been eaten,
+and to a consequent framing of dietary rules.
+
+The reproductive functions, in the same way, must have attracted the
+notice of man in very early times, as he must have found the harm that
+came from a blind following of instinctive desire.
+
+Above all other reasons, man must have been impelled by his instinctive
+love of life and fear of death to find some way out of his dangerous
+situation. To preserve his life, man must have sought wise choice of
+food and control of sexuality.
+
+Since the dawn of intelligence, man has tried to judge the unknown from
+the analogies given by what he knows best, that is to say, by his own
+self. Thus he came to attribute to everything around him qualities like
+his own qualities, and motives like his own motives. He came to think
+not only that all living beings were possessed of will and intelligence,
+but that inanimate things conducted themselves like human beings.
+
+Such a primitive idea is the basis of what Tylor has called “Animism,”
+the foundation of the philosophy and religion of savage and civilised
+man alike. When a man was seen to die, it was plain that he did not
+entirely disappear, but merely became transformed into a new condition.
+The dead body was not alive as we are, but, none the less, it was alive
+in a fashion of its own. This was the answer to the desire for the
+preservation of life, to the fear of death, that is to say, of total
+extinction. It is practically identical with faith in immortality and a
+future life.
+
+The animistic conception is almost world wide. It is plain that it
+afforded the most efficacious palliative for minds revolting against the
+inevitability of death, and that it harmonised with our intense will to
+live. “Such child-like ignoring of death,” wrote Tylor,[162] “such
+child-like make-believe, that the dead can still do as heretofore, may
+well have led the savage to bury with his kinsman the weapons, clothes,
+and ornaments that he used in life, to try to feed the corpse, to put a
+cigar in the mouth of the skull before its final burial, to lay
+playthings in the infant’s grave. But one thought beyond would carry
+this dim blind fancy into the range of logical reasoning. Granted that
+the man is dead, and his soul gone out of him, then the way to provide
+that departed soul with food or clothes or weapons is to bury or burn
+them with the body.”
+
+It is needless to recapitulate the various animistic customs which were
+in vogue among primitive peoples, and which have left marked traces
+amongst nearly if not all civilised races. The details may be found in
+the works of several authors, notably Tylor, Lubbock, and
+Waitz-Gerland.[163] I shall mention only a few, choosing those that seem
+most plain. The Turanians of Eastern Asia bury with their dead all sorts
+of implements, such as axes and flints, and food, such as meat and
+butter, believing that the departed will have need of these during the
+long voyage in the land of the spirits. A Tasmanian, on being asked why
+spears were buried with the dead, replied, as if the answer were
+self-evident, “Of course for the use in combat of him who has fallen
+asleep.” The Greenlanders place bows and other weapons in the tombs of
+their men, and knives, needles, and other instruments for sewing are
+buried with their women, in the full belief that such objects will be
+useful in the other world. In the Congo region, the curious custom
+exists of leaving a hole in the grave over the mouth of the dead body,
+and once a month passing into this hole meat and drink.
+
+Many races are not content to place merely inanimate objects in the
+graves. The Caribbeans, believing that the human spirit after death is
+carried to the kingdom of dead souls, sacrifice slaves on the tombs of
+their chiefs, in order that the latter may be attended in the next
+world. With the same object they bury dogs and weapons. The negroes of
+the Gold Coast, at the funeral of a great man, kill women and slaves
+that he may be provided for in the next world. Moreover, they bury with
+him his finest apparel, his gilded fetishes, and corals and pearls, so
+that the dead man may continue to make use of them.
+
+Tylor states that such animistic conceptions occur amongst all savages
+without exception. According to Herbert Spencer, if we take groups of
+the human race, such as tribes, societies, and nations, we find abundant
+evidence that all, or nearly all, have a belief, vague or clear, in the
+resurrection of a double of the dead man. It has been suggested that the
+origin of this widespread belief is the image of the departed that comes
+to us in dreams. These images are taken as real visits of the dead.
+
+In civilised races there are numerous relics of the old beliefs. The
+Spaniards set bread and wine on the graves of their relatives on the
+anniversaries of their deaths. The Bulgarians hold a feast of the dead
+on Palm Sunday. They eat and drink well, and then leave the remains of
+the banquet on the graves of their relatives that these may consume them
+in the night.
+
+Saint-Foix[164] relates that when Bertrand du Guesclin was buried at St.
+Denis, in 1389, several horses were sacrificed. The Bishop of Auxerre
+first blessed them, laying his hands on their heads, and then they were
+killed. At Treves, in 1781, at the burial of General Frederic Casimir,
+his horse, according to the custom of the Teutonic Order, was led in
+front of the bier, and when the General had been laid in the tomb, the
+horse was killed and buried with him.[165]
+
+Although the sacrifice of men and animals is no longer made by civilised
+peoples at burials, many funeral customs have an obviously animistic
+origin. In Russia, for instance, rice is placed alongside the corpse,
+and pine branches are strewed along the way to be traversed by the
+procession. The wreaths of “immortelles,” used so largely at funerals by
+the modern French, have an extremely ancient origin. They were employed
+by the Romans, and probably their use implied a conception of a future
+life in a region where plants and flowers grew.
+
+The belief in life after death, so widespread in the world, has been the
+foundation of all religions. I cannot follow this question here as
+closely as it deserves. To investigate it elaborately would take more
+space than this volume affords, and more knowledge than I possess.
+However, it is important to my argument to insist that, among races that
+have inhabited very different parts of the earth, that have had very
+different manners and have passed through different stages of
+civilisation, the conviction has been strong that death is not the end
+of all, but only a door leading from one kind of existence to another.
+Because of the high importance of the existence of this conviction,
+however, I must discuss some of the criticisms that have been made as to
+its universality.
+
+It has been asserted repeatedly that the idea of a future life was not a
+part of the Jewish religion, as formulated in the Bible. Haeckel has
+recently repeated a common opinion that belief in the immortality of the
+soul was absent from the oldest and purest form of the Jewish religion.
+“There is not to be found,” he said, “either in the Pentateuch or in
+those more ancient parts of the Old Testament which were written before
+the Babylonian captivity, any idea of the persistence of the human
+soul.” This is true only within limits. No doubt the books of Moses
+contain no reference to a future life nor to heaven and hell in the
+sense of modern creeds, but it is no less true that the ancient Jews
+shared with other races the conception of a survival after death. “Like
+almost all primitive nations,” wrote Renan,[166] “the Hebrews believed
+in a kind of double personality, in a shadow pale and thin which, after
+death, descended underground and passed a sad and colourless existence
+in the sombre halls of the dead. The dead dwelt there, without feeling,
+or knowledge, or memory, in a world without light, abandoned by God. At
+the most the old Hebrews hoped to obtain for themselves a quiet
+resting-place, a pleasant couch for the time when they would be with the
+dead. It comforted them to picture themselves as lying amongst their
+ancestors in quiet communion.”
+
+Ancestor-worship, which is associated closely with the idea of a future
+life, appears repeatedly in the Pentateuch. Jacob, when he felt death
+coming upon him, called his son Joseph and said unto him, “Bury me not,
+I pray thee, in Egypt; but I will lie with my fathers, and thou shalt
+carry me out of Egypt, and bury me in their burying-place.” According to
+Chantepie de la Saussaye,[167] “we are coming to recognise more and more
+how strongly the children of Israel, and in fact all other peoples, were
+tinged with animism and ancestor-worship.”
+
+It is very remarkable how the idea of a future life, which was vague in
+the early days of Israel, grew more and more clear. Ezekiel (sixth
+century B.C.), when he had “seen the visions of God,” prophesied of
+things to come, and declared that God would breathe life into the dry
+bones of the dead. The Book of Daniel (second century B.C.) expressed
+the same idea in a stronger fashion: “And many of them that sleep in the
+dust of the earth shall awake, some to everlasting life and some to
+shame and everlasting contempt” (Daniel xii. 2). “It is plain,” said
+Renan,[168] after quoting these words, “that Israel had now reached the
+last stage in the secular development of her ideas, and had reached the
+conception of the kingdom of God, as synonymous with the future world
+and the resurrection. As the conception of a soul distinct from the body
+was foreign to her, she could not conceive of a future life apart from
+resurrection of the body.”
+
+Still later, in the Talmud, the conception of a future life is clothed
+with details. Paradise is depicted as a region filled with sweet odours,
+while hell is an unclean place, thick with mire and smoke. According to
+the Talmud, in the life beyond the grave, “there is neither eating nor
+drinking; the good sit there with crowns on their heads and see God in
+bliss.”[169]
+
+At the date of the Cabalistic philosophy, the Jews had embraced the
+doctrine of transmigration of souls, and had come to believe that the
+spirit of Adam had entered David and would pass on to the Messiah. Some
+human souls passed into the bodies of animals, into the leaves of trees,
+or even into stones.
+
+It is plain that the idea of a future life was a part of the Jewish
+religion.
+
+It has been said, also, that the idea of a future life was absent from
+the religions of the Chinese. Büchner,[170] for instance, who came to be
+almost the official representative of the materialism of the second half
+of last century, asserts that “Buddhism, that famous religion, the most
+widespread and one of the most ancient, which counts among its followers
+nearly a third of the inhabitants of the earth, ignores completely the
+immortality of the soul.” Haeckel, also, in the “Riddle of the
+Universe,” a volume that sums up the materialism of the end of the last
+century, makes a similar statement. “The higher oriental religions
+include no belief whatever in the immortality of the soul; it is not
+found in Buddhism, the religion that dominates 30 per cent. of the
+entire human race; it is not found in the ancient popular religion of
+the Chinese, nor in the reformed religion of Confucius which succeeded
+it.”[171]
+
+This question demands a somewhat closer investigation. It has been
+thoroughly proved that the basis of the ancient religion of the Chinese
+was no more than an extreme development of ancestor-worship. Every
+important event in family affairs was accomplished “in the presence of
+the ancestors.” It was a bond with relatives beyond the grave. As in
+other cases of animism and ancestor-worship, meats were offered to the
+dead, and objects were buried with them to be of service to them.
+According to A. Réville,[172] the Chinese as a whole “fully recognised
+the conception of personal survival after death; if there were no other
+reason for stating this, it would be enough to point out that offerings
+of real food would be incomprehensible, if made to persons supposed to
+be non-existent or reduced to complete unconsciousness.” As they offer
+to the dead, food and clothing and precious things, it is plain that the
+Chinese think of life beyond the grave as not very different from this
+life. “The dead maintain their interest in the affairs and persons and
+food that was familiar to them.”
+
+As the idea of immortality became developed further, the Chinese
+modified their customs. Instead of offering to the dead material
+objects, as is still done by many peoples, they came to substitute
+emblems. “Houses and clothing and food imitated in paper, and dolls of
+paper and straw to represent slaves, are burned, so that the spiritual
+forms of these objects may be offered to the spirit they wish to
+honour.”[173]
+
+One of the chief motives of ancestor-worship is fear lest the dead, if
+neglected, may visit their wrath on the living by sending plagues and
+pestilence upon them.[174]
+
+The worship of the dead had laid hold of the Chinese so firmly that even
+Confucius, notwithstanding his intelligence and scepticism, paid it a
+large tribute. “Confucius the philosopher,” said Réville, “regarded it
+as a duty to offer to his ancestors the gifts of food that princes had
+sent to him desiring to honour him.”[175]
+
+Confucius and his followers were reticent and ambiguous in their
+references to a future life, but that attitude did not prevent them from
+“observing the customs and ceremonies as carefully as if they had had a
+confident faith in the immortality of the soul.”[176] Although Lao-tseu
+himself believed neither in heaven nor hell, and professed the most
+rationalistic views, his disciples none the less accepted the doctrine
+of immortality, and even came to believe in rewards and punishments
+after death.
+
+The followers of Lao-tseu, the Taoists, devoted themselves specially to
+the problem of immortality. They made efforts to discover an elixir that
+would be capable of prolonging earthly life to eternity. “One of the
+chief claims of Taoism,” wrote Réville, “was the possession of a
+specific against death. It was true that they admitted this to be not
+only very difficult to obtain, but still more difficult to employ.
+However, if certain rules were observed strictly they were at least
+confident of great prolongation of life. It was only the very few
+Taoists who had reached perfection who could hope to pass into the
+better world without being subjected to the pains of death.”[177] “And
+so some of the masters of Taoism, such, for instance, as Chang-Tao-Ling,
+ascended to heaven without dying, by climbing a lofty peak and vanishing
+into the skies.”[178]
+
+The ordinary Taoists accepted fully the idea of immortality. They
+“taught the doctrine of purgatory for those who were not evil. To arrive
+at this, Lao-tseu simply expanded and applied to mankind generally an
+idea that was already familiar to him, the conception of the
+transmigration of one soul through several successive bodies. By means
+of such expiatory transformations, a man who had not reached it directly
+through the holiness of his life, could attain the immortality of genii
+and the blessed.”[179]
+
+It was believed for long that the Taoists, following the teaching of
+their master, did not recognise a hell. But this opinion has had to be
+abandoned, because the “Taoist clergy have provided, in the temples
+dedicated to the tutelary deities of their cities, paintings
+illustrating the torments prepared for the guilty by the ten courts of
+justice that sit in the depths of an ocean hidden in the interior of the
+earth.”[180]
+
+Clearly then, many Chinese, both Taoists and followers of Confucius,
+believe in the existence of a world beyond the grave. However, the
+denial of immortality has been ascribed to Buddhists in particular.
+
+Buddha accepted the Brahmanist doctrine of transmigration of the soul.
+This has been established clearly on the evidence of several documents
+of admitted authenticity. Orthodox Buddhism is somewhat vague on the
+immortality of the soul. Buddha himself avoided making a decisive
+statement on this matter. In such circumstances “those who were
+terrified at annihilation, and who could not give up the hope of eternal
+happiness, interpreted the silence of Buddha according to their own
+desire, and inferred that he did not forbid them to hope.”[181]
+
+There are many instances of the evasions of Buddhist teachers when they
+were pressed with this disturbing question. Pasénadi, the king, once met
+Khémâ, the nun, a disciple of Buddha, renowned for her wisdom. The king
+put to her the following question: “Does the Perfect One (Buddha) exist
+after death?” “The Sublime One, O great king, has not revealed to us the
+existence of paradise beyond the grave.” “Then the Perfect One exists no
+longer now that he is dead, O reverend lady?” “Neither, O king, has the
+Sublime One revealed that He who is perfect does not exist now that He
+is dead.” “Am I to believe, then, O reverend lady, that the Perfect One
+still lives, although He is dead, and at the same time does not live? Am
+I to believe, O wise lady, that the Perfect One being dead, neither
+exists nor does not exist?”[182]
+
+Take again the mode in which Soumirmitá,[183] “the son of a god, and
+surrounded and preceded by a crowd of gods,” worshipped Bouddha
+(Tathâgata): “Thou art the physician, skilful to save, and who givest
+the gift of life everlasting.”
+
+The Buddhists, as they were not given clear doctrines on this subject,
+very naturally followed their inclinations by accepting the idea of life
+beyond the grave. And certainly Buddhism does not teach annihilation of
+the body after death, although this has been lightly taken for granted.
+On the contrary, it is so persuaded of survival after death as being the
+rule, that it grants only to rare and elect souls the privilege of at
+length laying down the burden of continuous life.[184]
+
+The Chinese Buddhists retained the fundamental conceptions of the
+ancient religion of their land and continued to worship their ancestors
+and to seek the readiest path to immortality. They soon came to
+transform Nirvâna into paradise, and to inculcate in the Chinese race
+the doctrine of future rewards and punishments. “The Buddhist
+monasteries in China for the most part possessed a set of little rooms,
+in which there were depicted, in vivid colours, crowded scenes from the
+eighteen hells of tribulation and lamentation. For there exist under the
+earth eight hells filled with the torments of fire, and ten with the
+equally terrible horrors of ice.”[185]
+
+The paradise of the Chinese Buddhists, or Ni-pan (Land of the Pure), is
+a region abounding in “gold and silver, and precious stones. Rivers of
+crystal run on golden sands covered with splendid lotus-flowers and
+traversed by delightful paths. Lovely music is always to be heard. Three
+times a day a shower of blossoms falls. There are to be seen there
+gorgeous birds, pheasants, and parrots, and many others; and these,
+every quarter of an hour, in a choir of melodious voices, trill out the
+beauties of religion and recall to their hearers the Buddha, Dharma, and
+Sungha. These are some of the wonders prepared for those who are born
+again after death. Into that land neither sin nor any evil enters.”[186]
+
+I need no longer accumulate details to show the falseness of the view
+that a third of humanity profess materialism to the exclusion of any
+belief in survival after death. On the other hand, it is quite certain
+that the vast majority of mankind is convinced that death puts no
+definite term to existence, and that this life is no more than a passing
+stage leading to a life to come. However, although many simple races
+believe that the future life is merely a continuation of this life, the
+more subtle-minded races present the future life as filled with delights
+for the good and with torments for the wicked.
+
+Such an idea of the next world, which is very generally accepted, is
+probably the basis of religions. From it have come the conceptions of
+supreme beings and divinities Many facts go to show that the primitive
+gods were no other than the relatives and ancestors of the living, now
+dead, yet living in another world and ruling the affairs of this world.
+Wicked ancestors became transformed into evil spirits, while good
+ancestors became mild and benevolent deities.
+
+Very many peoples offer prayers to their ancestors and treat them as
+gods. The Kaffirs pray and sacrifice to their dead relatives, believing
+that the spirits of the dead haunt their late dwelling-places, and,
+according to their characters, help or torment their descendants. As
+they are able to cause good or evil after death, these play the part of
+gods. But, as Lubbock points out (“Origin of Civilisation”), it must be
+remembered that the god of a savage is only a being like unto himself,
+although probably rather more powerful, and I shall show that there are
+many intermediate stages between true gods and mere dead parents whose
+malice is to be feared, or whose kindness is to be supplicated.
+
+The North American Indians[187] pray to the spirits of their
+forefathers for good weather or luck in hunting, and fancy when an
+Indian falls into the fire that the ancestral spirits pushed him in to
+punish neglect of the customary gifts, while the natives of Louisiana
+are said to have even gone so far as to build temples for dead men. In
+Polynesia “at Tanna, the gods are spirits of departed ancestors, aged
+chiefs becoming deities after death, presiding over the growth of yams
+and fruit-trees, and receiving from the islanders prayer and offerings
+of first fruits.”[188] In the Malay Islands “the souls of deceased
+ancestors are looked to for prosperity in life and help in distress.”
+In Africa ancestor-worship is well developed. The Zulu warriors,
+“aided by the amatongo,’ the spirits of their ancestors, conquer in
+the battle. Even the little children and old women, of small account
+in life, become at death spirits having much power, the infants for
+kindness, the crones for malice. But it is especially the head of each
+family who receives the worship of his kin.”[189] The Zulu adores his
+father, when he is a chief, above all others, and is convinced that a
+father remembering his love for his children, will not forget them
+when he is dead. “The Zulu follows up the doctrine of divine ancestors
+till he reaches a first ancestor of man and creator of the world, the
+primeval Unkulunkulu.”[190]
+
+So great is the number of instances that it is too difficult to choose
+from them. The fundamental idea is always identical, although details
+and accessories vary, as one passes from the hardly idealised relatives
+of negro tribes and goes progressively to the “Father Almighty, Maker of
+heaven and earth” of the Nicene Creed.
+
+The conception of a future life in the form of immortality or some
+kindred state, associated with the conception of many gods or of one
+God, has been developed to satisfy the craving for life and to combat
+the fear of death, that is to say, to defeat the greatest contradiction
+in the constitution of man. I must now inquire how far the different
+religions have been successful in this object.
+
+Many primitive races have absolute faith in the tenets of their
+religion, and believe in the promise of life beyond the grave as in a
+certain fact. Thus the aborigines of the Fiji islands are convinced that
+they will be born again, in another world, in the exact condition in
+which they leave this life; and so they wish to die before being
+afflicted with any infirmity. As it is very difficult to reach old age
+without being the victim of some illness or infirmity, when a man feels
+the approach of age, he tells his children that the time has come for
+him to die. If he himself fails to give this notice, the children
+undertake the duty. A family council is called, the day is appointed,
+and the grave made ready. The old man is allowed to choose between being
+strangled and being buried alive. The following instance will show the
+strength of a belief in life to come. Hunt, an English traveller, quoted
+by Lubbock, received a visit from a young native of Fiji, whose purpose
+was to give an invitation to the funeral of his mother which was to take
+place next day. Mr. Hunt accepted the invitation and joined the
+procession, but as he was surprised to see no dead body, inquired about
+it from the son. The son pointed out his mother, walking in the
+procession and as gay and animated as any of the others. Mr. Hunt stated
+his surprise, and asked why he had been deceived by being told that the
+mother was dead, when she was plainly as much alive and as well as any
+one else. He received the reply that the death festival was about to be
+celebrated; that presently they would bury her; that she was old, and
+that his brother and he, thinking that she had lived long enough, and
+should be put to death, had obtained her cheerful consent.
+
+This case is far from being solitary, because many villages have been
+described as containing no inhabitants of a greater age than forty
+years, all those older having been buried. It is not difficult to
+understand that death should have no terrors for persons possessed of a
+faith as strong as this. The American Indian, according to Lubbock, has
+very little fear of death. He does not fear transference to a realm in
+which, as he has been told all his life, there is no sorrow and
+abundance of joy.
+
+I know a case of a young girl of the Catholic faith who believed so
+firmly in the joys of Paradise that, when stricken with a mortal
+illness, she awaited death with a great impatience. Before she died, she
+cried out that “already she could see the beautiful flowers and hear the
+sweet music of the birds that fill heaven.”
+
+But it is rare to find faith so strong in such a case. More often faith
+is not strong enough to subdue the fear of death, and in proof of this I
+may recall the instance of the clergyman already given.[191] Stricken
+with an incurable disease, he, in spite of his religion, underwent
+extreme agony, and could not reconcile himself to the idea of death. The
+fear of death showed itself so strongly in this case that I have chosen
+it as a characteristic instance of the feeling.
+
+It is only with fanatics and simple or primitive persons that blind
+faith can subdue this instinctive fear. For this reason, since the most
+ancient times, religions have sought out something more than the promise
+of paradise to mitigate this chief disharmony of our nature. In this
+connection the doctrines of Buddha are those most interesting. Here I
+shall not deal with that modified and transformed Buddhism, in which, as
+I have already shown, there was a return to the doctrine of future life,
+with its hell of torments and heaven filled with delights.
+
+Buddha made no reference to the great blot on human life. His doctrine,
+in its original form, was extremely pessimistic. Take, for instance,
+some of his sayings on this subject: “Miserable in truth is this world,
+in which there is beginning, birth, growing old, death, disappearance
+and renewal. But we know not how to escape from this world, full of
+horror though it be. Alas, because of old age, illness, death, and their
+like, we know not who shall put an end to this world, which is so full
+of horror. To all who are, there comes old age, and illness, and death,
+and their like.”[192]
+
+When the Buddha came upon the sorrows of the world, as I have already
+described (p. 119), he reflected as follows: “Woe upon youth, threatened
+by old age! Woe upon health, which so many maladies destroy! Woe upon
+the life of man, which lasts but a little space! Woe on the temptations
+of the flesh, which lure the heart of the wise! Would that there were
+neither old age nor illness, nor death and the pains of death, which
+come from the five elements of life (Skandhas)! Would that there were
+neither old age nor illness nor death, which are for ever bound up
+together! Nevertheless, when I return again I shall consider
+deliverance.”[193]
+
+Having pondered for many days on these problems, Buddha thought that he
+had discovered the only solution, and taught men resignation. When a man
+was young he would ask of his father: “Lord, would that old age would
+never come upon me, and that I should keep for ever the warm colour of
+my youth; that I should be always filled with health, and that no
+disease should come near me; that my life should be prolonged for ever,
+and that death should pass me by! Such an one later on must learn to
+give up these longings.”[194]
+
+In his famous “Sermon at Benares,” Buddha gave in brief the outlines of
+his doctrines in the following words: “Hear, oh monks! the holy truth of
+the springs of sorrow! Sorrow is born of lust of life, that drags us
+from incarnation to incarnation, and of pleasure and desire, which seek
+their fulfilment hither and thither; the lust of pleasure, the lust of
+life, the lust of power. Hear, oh monks! the holy truth of the conquest
+of sorrow; it is the killing of this lust by the utter abandonment of
+desire, the giving up of all desire, the forgetting of all desire, the
+freeing of the body of all desire, until there is no place left for
+desire.”[195]
+
+In such a spirit of resignation, Buddha became himself a monk, and lived
+according to the strict rules of the pure life that he himself had laid
+down (“the belief pure, the will pure, the language pure, the deeds
+pure, the means of livelihood pure, the study pure, the attention pure,
+the meditation pure”). However, he did not find many kindred souls to
+follow the same precepts. Buddhism soon moved away from these original
+tenets, and became a religious doctrine of the ordinary kind.
+
+We are inclined to associate with Buddhism the doctrine of Nirvâna, as
+if the latter were the goal to which human life should be directed. Many
+philosophers, and the pessimists chief among them, naturally with
+Schopenhauer at their head, have adopted Nirvâna as the goal of mankind,
+as they see the world. However, the word Nirvâna has had many
+interpretations put upon it, the which is less surprising as Sanscrit
+scholars differ. I do not intend to join in the discussion, as I myself
+am not acquainted with Sanscrit, upon which the argument must be
+founded. However, I cannot pass it by without comment on the pretext
+that it has not yet been settled definitely by specialists, as it is the
+case that many thinkers regard Nirvâna as the goal of human existence.
+
+For long Nirvâna was represented as a sort of blank, in which there was
+no display of any mental operations. Max Müller,[196] the celebrated
+Oxford professor, opposed this interpretation on the ground that,
+according to him, in “all passages of Buddhistic origin in which Nirvâna
+occurs there is nothing to betoken annihilation. Most of these passages,
+if not all of them, would be quite unintelligible if we were to replace
+in them the word Nirvâna by the word annihilation.”
+
+Many other specialists share this view, and cannot agree that the goal
+of human life was to be annihilation. Rhys Davids, for instance, thinks
+that Nirvâna is to be interpreted as a tranquillity of the soul,
+possible of achievement in this life, and that the word is best
+translated by the term “sanctity.” According to him, Nirvâna does not
+mean extinction or annihilation, but rather freedom from the great
+passions, such as envy and hate. Pfungst[197] agrees with Max Müller; he
+is convinced that the first adepts of Buddha could not have conceived of
+Nirvâna as extinction. Dahlmann[198] on the other hand, tries to prove
+that Nirvâna in its primitive signification implied the abolition of the
+will to live, and really corresponded to annihilation.
+
+I must add, however, that Nirvâna did not occupy a place in Buddhism so
+important as has been ascribed to it by several commentators. In many of
+the Buddhist authorities mention of Nirvâna is only accidental. In the
+“Lalita Vistara,” for instance, the word occurs very seldom, and then
+only in unimportant connections. However, the latter document contains a
+good deal that serves to explain the conception of Nirvâna.
+
+When the young Buddha, still very exacting, asked his father to obtain
+for him perpetual youth, health, life everlasting, and freedom from
+death, he added the following words: “Lord, if you cannot give me these
+four gifts, at least bring it about that after this life I shall have no
+more metempsychoses.”[199]
+
+As I have already stated, Buddhism had embraced the Brahmanistic
+doctrine of transmigration of souls. According to the legend, before his
+birth as a prince, the Buddha had passed hundreds of earlier existences.
+His soul had been the soul not only of fifty-eight kings, but of
+eighteen monkeys, four horses, four snakes, three lizards, two fish, and
+of other creatures.[200] Such continual transferences of the soul to so
+many different animals was a source of perplexity and sorrow to
+believers. It was natural that a great thinker like Buddha should have
+conceived the desire of sparing himself and his faithful followers so
+many transmigrations. He thought of these rebirths as a great evil, from
+which a pure life might set one free.
+
+In the poetical language of the Hindoo Buddhists, metempsychosis was
+compared to the ocean; the waves that change from moment to moment were
+the continual rebirths; our temporary body was the foam of the crests of
+the waves, while Nirvâna was the opposite shore. He who reaches Nirvâna
+would never again plunge into the great sea of Sangsâra. In a passage
+quoted by Rhys Davids, and ascribed to Kâma Sutta, it is stated
+expressly that “the sea is an image of the Sangsâra or transmigrations,
+while Nirvâna is an island upon it. Once the shores have been reached, a
+soul will no longer be plunged in the waves of the ocean, and will be
+freed from the successive births of metempsychosis.”
+
+In other words, to avoid being tormented after death by perpetual
+rebirths, some of which may be humiliating, it is necessary to live a
+pure life and so to secure repose or Nirvâna. Nirvâna is by no means the
+cessation of all consciousness, but merely the end of transmigrations.
+From such a point of view, it is possible to interpret all, or at least
+nearly all, the passages in which Nirvâna is spoken of.
+
+When he was old and full of disease and afflicted with grievous pain,
+Buddha, being at the point of death, thought of his disciples and called
+them to him and said: “It is not meet that I should enter Nirvâna
+without having spoken with those who have cared for me, without speaking
+to the community of disciples. By the force of my will I shall subdue
+this disease and hold the life within me.” Some time afterwards, the
+reverend Ananda went to Buddha and spoke to him, saying amongst other
+words as follows: “The Sublime One will surely not enter into Nirvâna
+ere he has made known unto the community of disciples his wishes
+regarding them.” “Growing more and more feeble, the spirit of Buddha
+passed from ecstacy to ecstacy without ceasing, and knew every delight;
+then he entered into Nirvâna. And the earth trembled, and thunder rolled
+across the skies.”[201]
+
+It is clear that in this passage Nirvâna was associated with death. But
+it was with the death of a saint who had lived a pure life.
+Metempsychosis would not be inflicted on him, and he would enjoy repose.
+It is probable that the term Nirvâna later on came to be applied to the
+state of mind of a saint who, by living the pure life, would avoid
+transmigration after death.
+
+As the importance of Nirvâna lies in its contrast with metempsychosis,
+it is easy to see why the precise state of mind involved in it has not
+been described exactly. However, a survey of the Buddhistic writings
+makes it plain that at least Nirvâna was not associated with
+annihilation. In this respect Max Müller’s verdict must be taken as
+correct.
+
+Buddha’s attempt to remedy the ills of human life, then, lay in a
+complete renunciation of all the joys and pleasures of life, and in
+perfect resignation. The mere fact that primitive Buddhism did not
+persist, but rapidly passed into an ordinary religion, is sufficient
+proof that Buddha did not achieve his purpose. It was the promise of a
+life to come that attracted so many men and spread Buddhism over so
+large a part of the earth. However, this faith has been able to maintain
+itself only in certain strata of society to which the rationalistic
+conception of the mental processes has not penetrated. Since the
+awakening of the scientific spirit in Europe, it has been recognised
+that the promise of a future life has no basis of fact to support it.
+The modern study of the functions of the mind has shown beyond all
+question that these are dependent on the functions of the body, in
+particular of those of the central nervous system. A slight lowering of
+the rate of the circulation of the blood, a fleeting anæmia of the
+brain, at once arrests consciousness, that is to say, the fundamental
+sensation of the individual mental life. Anæsthetics, used in doses so
+small that they do not influence certain parts of the nervous system,
+as, for instance, those that control the heart and lungs, completely
+abolish consciousness. Persons who are put under chloroform for surgical
+purposes fall into a state of absolute unconsciousness. Sometimes, after
+undergoing painful sensations, especially sensations of oppression, the
+patients imagine themselves to be in rapid motion, and in a few moments
+have the sensation of falling into an immense gulf, after which comes
+nothingness, the annihilation of sensations and of consciousness. In
+other cases, patients, without any sensation of catastrophe, lose all
+idea of reality, and every psychic and sensorial function is abolished.
+Such states are very closely similar to death, which indeed is the
+result, in certain rare instances, of the ordinary process of being
+chloroformed.
+
+Neither the narcosis produced by chloroform nor that produced by any
+other form of anæsthetic, affords any particle of ground for the view
+that there is consciousness in any form apart from the body. The action
+of morphine sometimes brings about a strange current of happiness and an
+apparent weightlessness of the body; but here again there is no
+suspicion given as to the existence of any mental phenomena apart from
+the body.
+
+Consciousness of personality is of supreme interest from the point of
+view of personal immortality, and this mental phenomenon develops only
+slowly and progressively in an infant. This fact, again, like the facts
+of narcosis, shows the dependence of consciousness on the action of the
+bodily organs. Just as our consciousness comes out of nothing in the
+first months, or years, of our life, so it will pass into nothing at the
+end of our life.
+
+Mental disease confirms this conclusion, and it, too, gives no ground
+for the belief in a survival of the mind after death.
+
+Certain internal sensibilities in the depths of our organism survive our
+personal consciousness. When the heart has ceased to beat, and when the
+anæmic brain is certainly incapable of personal consciousness, some
+portions of the body may still retain vitality. The muscular fibres are
+still able to contract when they are stimulated, and the white
+corpuscles of the blood can still exhibit their specific movements. It
+is certain, moreover, that these white corpuscles possess a specific
+sensibility, and, by a sort of sense of taste, respond to the kind of
+environment that surrounds them. Our consciousness, however, is
+absolutely out of touch with the sensations of these globules, which,
+however, none the less are part of our organism. It happens, therefore,
+that in certain diseases, the white corpuscles, stimulated by the
+presence of particular substances, perform extensive movements of
+migration within our bodies. Such migration is quite outside the sphere
+of consciousness. The corpuscles, directed by their sensibility, are in
+constant pursuit of microbes that have entered the body, and yet these
+actions, too, are not made known to our consciousness. In the same
+fashion, the thousands of active spermatozoa in the male organs and the
+ova in the female possess specific sensibility. These reproductive
+elements contain the germ of individual consciousness, but it is not
+until they have developed into the new generation that it is possible to
+impute to them individual consciousness, and the organism that shelters
+them has no idea of what it harbours. The sensibility of the white
+corpuscles and of the many other cells composing our body, although
+certainly a reality, has no part in the absolutely special sensation
+that we call individual consciousness, and which is all we think of in
+wishing to escape death.
+
+The idea of a future life is supported by not a single fact, while there
+is much evidence against it. The phenomenon of intercommunication across
+a distance, sometimes called telepathy, may be actual, but affords no
+support to the conception of the existence of souls apart from bodies.
+It may be that emanations are given off by certain organs, and that
+these are capable of being appreciated by the organs of another body at
+a distance; but, even if such were the case, we should have to deal
+simply with other bodily functions. Moreover, the supposed phenomena
+that fall within this category are so rare, so difficult to observe, and
+so obscure, that no certain argument for the continuance of existence
+after death can be deduced from them.
+
+It is easy to see why the advance of knowledge has diminished the number
+of believers in the persistence of consciousness after death, and that
+complete annihilation at death is the conception accepted by the vast
+majority of enlightened persons.
+
+Apart from their chief function of consoling men for the inevitability
+of death, religions have concerned themselves with some of the results
+of other disharmonies of the human constitution. From time immemorial
+they have claimed the direction of diet, the control of the reproductive
+functions and the prevention or cure of all kinds of disease.
+
+The dietary regulations given by the religions are familiar. Even at the
+present day, the cookery of many races is regulated by their religion.
+The Jewish diet, notably, is regulated by the Mosaic law, down to the
+most minute detail. For instance, it was forbidden to eat the blood of
+animals. Moses commanded: “Notwithstanding, thou mayest kill and eat
+flesh in all thy gates, whatsoever thy soul lusteth after, according to
+the blessing of the Lord thy God, which he hath given thee; the unclean
+and the clean may eat thereof, as of the roebuck, and as of the hart.
+Only ye shall not eat the blood; ye shall pour it on the earth as
+water.”[202] Later on: “Only be sure that thou eat not the blood; for
+the blood is the life; and thou mayest not eat the life with the
+flesh.”[203] “Thou shalt not eat it, that it may go well with thee, and
+with thy children after thee, when thou shalt do that which is right in
+the sight of the Lord.”[204] The Books of Moses also contain receipts
+for the cooking of certain meats. “Eat not of it raw, nor sodden at all
+with water, but roast with fire, his head with his legs, and with the
+purtenance thereof.”[205]
+
+It has been suggested that these rules were founded on ideas of hygiene
+in consonance with the results of modern science. Some of them, it is
+true, such as the prohibition of uncooked or partially cooked meat, are
+confirmed by our modern knowledge. But the greater number of the Mosaic
+rules, as, for instance, the prohibition of the consumption as food of
+blood or the flesh of pigs or hares and so forth, are in direct
+opposition to a modern knowledge of hygienic diet. Religious cookery has
+no more than a historical interest.
+
+The religions have been greatly occupied with the functions of the
+reproductive organs. Most of the founders of the great faiths have paid
+a keen attention to the disharmonies of this side of our constitution.
+They became persuaded of the merit of abstention, which they practised
+themselves and preached to others. Buddha, after devoting his youth to
+all the pleasures and not being satisfied, passed to absolute
+asceticism. He and his adepts formed an order of monkhood, on which an
+absolute celibacy was imposed. If a member of the order had intercourse
+with a woman, he was considered to be as guilty as a murderer or a
+thief. In the Buddhist rules framed even for laymen, “sexual intercourse
+outside marriage was forbidden, on the ground that it was
+degrading.”[206]
+
+The views of the Christian religion on sexual matters are well known.
+The leaders of Christianity abstained from sexual intercourse and
+recommended their conduct to others. St. Paul more than once affirmed
+his own continence. “For I would that all men were even as I myself; but
+every man hath his proper gift of God, one after this manner, and
+another after that. I say therefore, to the unmarried and widows, It is
+good for them if they abide even as I; but if they cannot contain, let
+them marry, for it is better to marry than to burn.”[207]
+
+The religions of savage races are equally concerned with the
+reproductive functions. There are many extremely strange facts known
+concerning this matter, and among such I may mention that the Sandwich
+Islanders have a deity who presides at abortions. This god is made in
+the form of an elongated wooden instrument, and is known as “Kapo.” The
+upper part of the deity is shaped into a grotesque head, while the lower
+portion terminates in a point and serves to induce abortion by entering
+the uterus and rupturing the fœtal membranes.[208]
+
+Many other idols are used by savages as protections against disease.
+Ploss-Bartels,[209] in his treatise on “Medicine among Primitive Races,”
+has described a large collection of talismans of this kind. The ruling
+idea in the manufacture of these is that diseases are due to the
+presence of evil spirits, who are to be scared away as soon as possible.
+The Goldi of Siberia construct straw or wooden figures of men and
+animals to absorb the spirits of diseases. The Guilaks make wooden human
+figures, on the breasts of which are fashioned images of toads. These
+talismans are used as remedies for diseases of the chest and stomach.
+
+In higher forms of religion there remain abundant traces of such
+notions. Even Martin Luther declared that disease was supernatural in
+origin. “Behold a matter on which there is no room for doubt,” he
+stated, “and that is that the plague, fevers, and other diseases are the
+work of the devil.” A number of religious ceremonies were specified as
+the best remedies for diseases.
+
+The plague has left many deep marks on human history, and it is natural
+that a malady so terrible should have attracted serious attention. It
+was usually attributed to divine wrath, which was to be appeased by
+purification and sacrifice. Human beings were slain on altars to appease
+the wrath of God and to lessen the mortality from plague.
+
+Such religious customs have disappeared almost completely with the
+advancing culture of man, but traces of them survive and become apparent
+on occasions. Quite recently, when the King of England, Edward VII., was
+afflicted with an abdominal suppuration, he was given the assistance of
+the most highly skilled modern surgery, but at the same time special
+services were held in the churches to aid the cure of the royal invalid.
+
+Every one has now come to regard such events as mere relics of old
+customs without intrinsic importance. Hygiene in the kitchen and the
+prevention of disease are no longer under the control of religion, but
+are regulated on scientific knowledge obtained by the experimental
+method. I need pay no further attention to these matters. However,
+religion is still occupied with the problem of death. The solutions
+which as yet it has offered cannot be regarded as satisfactory. A future
+life has no single argument to support it, and the non-existence of life
+after death is in consonance with the whole range of human knowledge. On
+the other hand, resignation as preached by Buddha will fail to satisfy
+humanity, which has a longing for life, and is overcome by the thought
+of the inevitability of death.
+
+It was to be expected that in such a state of affairs philosophers would
+have sought an issue from the dilemma. Certainly many philosophical
+theories have been propounded to explain life and death. As the subject
+is of extreme importance I shall reserve a chapter for it.

+ ATTEMPTS IN SYSTEMS OF PHILOSOPHY TO REMEDY THE ILLS ARISING FROM THE
+                 DISHARMONIES OF THE HUMAN CONSTITUTION
+
+
+  Some philosophical systems are in intimate union with religions—Ideas
+  of ancient philosophers on the immortality of the soul—The teaching of
+  Plato—The scepticism of Aristotle—The Stoics—Cicero, Seneca, Marcus
+  Aurelius—Modern philosophical systems—Pessimism and its origin—Lord
+  Byron—Theories of Schopenhauer and Hartmann—Mailaender’s philosophy of
+  deliverance—Criticisms of pessimism—Max Nordau—Ideas of modern
+  thinkers on death
+
+
+Systems of philosophy are closely attached to religious doctrine.
+Buddhism, for instance, originated in a philosophic theory which
+acquired a religious character in the hands of the followers of Buddha.
+Similarly, many systems of philosophy are merely religious dogmas which
+it has been attempted to support by rational argument apart from
+supernatural revelation.
+
+The idea of life beyond the grave has long since furnished one of the
+principal bases of various philosophic doctrines, the ultimate object of
+which was to solve the problem of death. Ancient philosophy is full of
+such. Plato describes the tragic death of his master Socrates, and in
+connection with it expresses very clearly his ideas upon death. He puts
+these words in the mouth of Socrates in the “Phaedo”: “Far from being
+depressed by the death of a friend, I felt, on the contrary, that he was
+to be envied; as I witnessed his attitude, and listened to his words,
+and noticed the courage with which he faced death, I became convinced
+that he did not quit this life without some divine support that drew him
+towards another world in which he would find the most perfect happiness
+man could wish.”
+
+Plato attributes to Socrates a very definite view as to future
+retribution: “In truth,” said Socrates, “if I did not expect to find in
+another life gods at once good and wise, and men better than those of
+this life, it would be foolish of me not to be disturbed by the approach
+of death. But I know that I look to finding myself among just men. I do
+not fear to die, because I am confident that something still remains
+after this life, and that, according to the old belief, the good will be
+treated better than the bad.”
+
+As such views were not derived from a body of revealed truth, it was
+necessary to support them by reasoning. Plato therefore went on to try
+to convince us of the immortality of the soul by speculative hypotheses.
+He recalled the Pythagorean doctrine of metempsychosis, and suggested
+that the souls who had abandoned themselves to injustice, tyranny, and
+plunder would pass into the bodies of wolves and hawks and falcons, for
+souls of that nature could not go elsewhere; while the souls of those
+who had practised the social and civic virtues known as temperance or
+justice, would inhabit the bodies of peaceful and gentle creatures such
+as bees and ants, or would even enter other human bodies and again
+become good men.
+
+Plato referred also to the law of contrasts in support of his theory.
+“As the most strong often springs from the feeblest, or the most swift
+from the slow, so life gives rise to death, and from death life
+springs.” “From that which is dead,” said Socrates, “is born all that
+lives and has life. And so our souls after death pass to the infernal
+regions.” “As we must grant that the dead are born from the living as
+much as the living from the dead, it is plain that the souls of dead men
+exist somewhere, whence they may return to life.”
+
+By such arguments Plato tried to prove the immortality of the soul, the
+fundamental basis of his philosophy, and put them in the mouth of his
+master Socrates on his deathbed. In the dialogue he tried to refute all
+kinds of objections. But, in spite of the assurance with which he
+formulated his doctrine, there may be seen underlying the argument a
+note of doubt, and it is just this that distinguishes philosophy from
+religion.
+
+It is evident that the whole of Plato’s system was the result of an
+effort to solve the problem of death. Again and again he said that the
+true philosopher lived only to be ready to die; that being so, he
+declared it to be childish for men at the last to shrink from what they
+had so long been making ready for. It was himself that Plato wished to
+convince of a future life. “I do not seek,” he said, “to persuade all
+those who are here of the truth of what I say, although to do so would
+greatly please me; what I aim at is to convince myself. Behold me, dear
+friend, in pursuit of an argument that, as you see, interests me deeply;
+if what I say turns out to be true, it is good to have believed it, and
+if there be nothing after death, at least I have gained this, that while
+I am still with you, I am not borne down with grief.”
+
+The doubt which was only latent in Plato was much more active in some
+other ancient philosophers. Aristotle[210] at one time admitted that
+part of the soul was immortal, but that the other part was mortal. The
+two parts came together at the beginning of a life and separated at its
+end. Later on, however, Aristotle abandoned this theory of the
+immortality of the personal consciousness, and argued strongly against
+the Platonic theory of the immortality of the soul, although, however,
+he still believed in the indestructibility of the “rational spirit,” an
+immortal principle.
+
+The Stoics still further developed such a conception. They held that
+besides the individual soul there was a universal soul, a presiding
+influence in which all others had their being.
+
+Cicero, again, discussing old age and death, tried to establish belief
+in a future life. “I am convinced,” said Cicero to Scipio and Laelius,
+“that your illustrious fathers, who were so dear to me, are still full
+of life, and of the only life worthy of the name; for the body is, as it
+were, our prison-house, within which we must accomplish the tasks laid
+on us by necessity. When I think of the activity of the human spirit,
+its vast memory, its prevision, its store of art and knowledge, and
+experience, I am convinced in the depths of my being that an existence
+with such qualities cannot be mortal. The soul is continually active,
+and its activity comes not to it from without; the soul is a
+self-supporting activity, and cannot come to an end. Moreover, as the
+soul is a simple substance, unalloyed by any mixture of materials, it
+can neither be divided nor made to perish.” By such arguments Cicero
+sought to prove the immortality of the soul. “I will tell you,” he said,
+“why old age, so far from being grievous to me, is full of delight.” But
+in the end, he himself saw the weakness of his proof, and the note of
+scepticism appeared in him more strongly than in his predecessors, so
+that he came to say as follows: “If I am deceived as to the immortality
+of the soul, I am deceived gladly, and I would not have the belief torn
+from me while I live. If, when I am dead, all feeling is arrested within
+me, as some pretended philosophers hold, at least I have not to fear
+that after my death they will come and mock me for my error.”
+
+Scepticism becoming more and more definite, belief in the immortality of
+the soul persisted only in the purely religious form. Philosophical
+systems freed themselves of it, and replaced it by a vague form of
+pantheism.
+
+Seneca tried to support the thesis of immortality, but one gets the
+impression strongly that there was no vigour in his belief. He is
+content with poetry rather than with reason. “The events of this mortal
+life,” he wrote in one of his celebrated “Letters,” “are the mere
+prelude of a better and more lasting existence. As our mother’s womb,
+bearing us for nine months, shapes us not to live there for ever, but
+for our place in this world in which it places us, with the strength to
+breathe this air and to withstand surrounding things: so, also, the time
+that passes from our infancy to our old age is a preparation for a
+second birth. Another beginning and another world await us. Until then,
+we could not endure, save from afar, the splendour of the heavens. Learn
+then, O man, to face without a shudder the decisive hour, the last hour
+of the body, but not of the soul. What you see around you consider but
+as the furniture of an inn; soon you are going further on. The day that
+you dread as your last day is your birthday into immortality.”
+
+In the midst of these glowing visions, however, Seneca is assailed by
+dark and gloomy thoughts. “Yes,” he cried, “all that is must perish;
+death comes to every living thing. Every day, every hour, reveals to man
+the coming of death; there is always some new lesson to remind him of
+the fragility he had forgotten, and from a dream of eternity to turn his
+thoughts to the grave.”
+
+These heights and depths of spirit led Seneca towards a new theory in
+which he gave a final expression of his views on the great problem of
+human existence. “All beings pass through definite stages; they must be
+born, grow and die. The stars that we see revolving above us, the earth
+on which we are carelessly scattered and which seems to us so solid; all
+is threatened and all will come to an end. Old age comes on everything;
+although the period is very different, the same end comes to everything.
+Everything that now is will cease to be; but for all that the world will
+not perish; it will dissolve. Dissolution is destruction for us. As a
+matter of fact we think of things only as they concern ourselves; our
+degenerate soul, incapable of detaching itself from the body, sees
+nothing beyond that; none the less we should endure the idea of the
+death of ourselves and of those near to us with a greater fortitude were
+we to realise that nature is a constant routine of birth and death, that
+all composite bodies must dissolve, that the dissolved substances
+reform, and that the creative power of God displays itself in this cycle
+of change throughout the universe.” From such a final conception of the
+universe he draws the consolation: “A great soul should know how to obey
+God and submit willingly to the order of the universe. If it be not for
+a better life that we are to quit this life, if not to find a home in
+the skies more tranquil and more brilliant, our souls, free from
+suffering, will return to the spirit that gave them birth and will
+mingle in the great all.”
+
+In other words, abandoning the image of life after death that played so
+consoling a part in primitive beliefs, philosophy became content to
+advocate resignation to the inevitable laws of nature, and to console
+itself with the promise of a vague return to some universal, eternal
+principle.
+
+The conceptions of the Stoics, especially in the form presented by
+Seneca, found an ardent and brilliant exponent in Marcus Aurelius, whose
+“Thoughts” are known to all the world. He had much to say of the problem
+of death and of the attitude of the philosopher towards it. “Death,”
+said Marcus Aurelius, “like birth, is one of nature’s mysteries. In the
+two are present the same elements: in the one case in the phase of
+combination, in the other in that of dissolution.” In death “there is
+nothing repugnant to the essence of an intelligent being, nor to the
+general plan of our nature.” But his ideas on death were vague. “Death
+may perhaps be a dispersal or resolution into atoms, or an annihilation
+in the sense of extinction or deplacement.” “Alexander of Macedon and
+his mule-driver were reduced at death to the same condition, that is to
+say they returned alike to the originating principle of the universe, or
+one and the other were scattered as atoms.”
+
+Although he was definitely a deist, Marcus Aurelius was undecided as to
+the immortality of the soul. “If souls have not disappeared,” he said,
+“how can the air contain the eternal generations of them?” “Remember
+well,” he said in another place, “that that feeble and composite
+creature, your soul, will one day resolve into its atoms; the faint
+spark of life will be extinguished, or be assigned to some other
+dwelling-place.” Clearly enough, there was no consoling hope of a future
+life to be derived from these halting dubieties. It was needful to
+replace by some other anodyne the belief that for so long had brought
+comfort to poor humanity.
+
+Marcus Aurelius tried to counteract the fear of death by the following
+reflection: “To fear death is to fear either being deprived of all
+feeling or being subjected to some other kind of feeling. But, if we are
+deprived of all feeling, we shall have no evil to fear; if we are to
+find new kinds of sensations, our existence will be different, but still
+existence.” However, he probably realised the weakness of such a
+consolation, for he tried to link the problem of death with the general
+principles of human conduct.
+
+As I mentioned in the first chapter of this volume, Marcus Aurelius,
+like many of the philosophers of antiquity, held the view that man ought
+to live according to the dictates of human nature. The theory recurs
+again and again in his “Thoughts.” “The fig tree lives according to its
+kind, the dog like the dog, bees like bees, and man like man.” He
+expresses this view still more emphatically in the following words: “Man
+must live in conformity with the laws of his nature.” “No one will
+prevent you from living according to the laws of nature, and nothing can
+happen to you that is not in accordance with nature’s universal law.”
+“Neither hand nor foot can do that which is contrary to the laws of
+nature, because the foot can only fulfil the functions of the foot, and
+the hand those of the hand. Similarly with man, to behave as a man is
+not to defy nature’s laws, because it is only fulfilling the functions
+of man. And that which is not against nature cannot be evil.”
+
+Being full of this theory, Marcus Aurelius applied it to death, which,
+being a natural phenomenon, was to be accepted without protest. “For,
+after all, nature forges the links and nature breaks them. Is she about
+to sever them? Very well, let us then say farewell as if we were taking
+leave of our friends, but let there be no tearing of the heart strings,
+and let us go willingly, and so avoid being dragged away. This, too, is
+in accordance with the laws of nature.” “Philosophy,” according to
+Marcus Aurelius, “is to await death peacefully, and to regard it as
+merely the dissolution of the elements which compose the human frame.
+Such is the law of nature, and whatever is in conformity with nature is
+not evil.”
+
+Death, being a phenomenon in conformity with nature, must be submitted
+to. “Do not abuse death,” advises Marcus Aurelius, “but accept it with
+resignation, as being in accordance with the will of nature. Do we not
+pass on from infancy to youth, grow up, and become tall and attain
+manhood? Do not our teeth come, our beards grow, and our hair turn
+white? If we marry, do we not beget children? Are not all such events in
+their due season, and the work of nature? Death comes through the same
+agency. It therefore behoves a wise man to approach death with neither
+anger, repugnance, nor contempt, but to await it like any other
+operation of nature.” _Resignation_, then, is what this form of
+philosophy amounts to. Not only must death be accepted as inevitable
+when it comes after a long life, but even if it surprise us at an
+unexpected time. “He who dies after reaching the uttermost limits of
+human life,” says Marcus Aurelius, “has reached no further than he who
+comes to a premature end. It is the same in the end, whether there are a
+hundred years to look back upon, or whether there are only three.”
+
+In his book on Marcus Aurelius, Renan[211] compares his philosophy of
+resignation with the Nirvâna of the Buddhists. “Like Jesus, Çakya-Mouni,
+Socrates, Francis of Assisi, and three or four other wise men, Marcus
+Aurelius was victor over death. He could laugh at it, because it had no
+longer any meaning for him.” But, just as the theories of Buddha became
+transformed into a religion which promised the immortality of the soul,
+and as Nirvâna gave way to the Paradise of the Easterns with its
+delights, so the sceptical resignation of ancient philosophy was
+vanquished by Christianity with its promises of a future life and
+immortality.
+
+Thus, in the course of the centuries, philosophy has been drowned in the
+floods of sentiment and of religious notions, and it has been a labour
+of Sisyphus to restore reason to humanity. There is the less need to
+follow the stages of this resurrection, as, in the end, they come to
+little. For long, philosophical systems set themselves the task of
+supporting the dogmas of religion by arguments independent of divine
+revelation. The gods were replaced by philosophy or by matter, and an
+effort was made to solve the eternal and disquieting problem of death by
+proving the immortality of the soul.
+
+The philosophers of the early renaissance of human thought accepted the
+chief religious dogmas as established truth. Plotin regarded the
+immortality of the soul as a self-evident truth that required no proof.
+He argued against a resurrection of the body, but accepted the
+transmigration of souls.
+
+Although Spinoza had given up the conception of the immortality of the
+soul in the ordinary sense, he accepted the Aristotelian idea that “the
+human spirit could not be destroyed absolutely with the body, but left
+some eternal remnant.” Death, in his view, was a kind of eternal life, a
+merging with the absolute, a return to the immortal and universal
+substance.
+
+Philosophers have exhausted themselves in the study of the foundations
+of human knowledge with the sole object of demonstrating the truth of
+religious dogmas. In spite of his scepticism, Kant tried to prove the
+genuineness of human knowledge, and to found on that a conviction of the
+future life and of the existence of God. Fichte set himself the same
+task, but he was forced to recognise that “immortality cannot be deduced
+from natural phenomena,” and that it “is supernatural.” “Although we
+cannot understand the possibility of eternal life, it still may be
+possible, for it transcends human knowledge.” Hegel reached a
+pantheistic conclusion and believed in the human soul being re-absorbed
+by the absolute.
+
+These idealistic systems, when they reached their final point, provoked
+a reaction consisting in the rejection of all formulas based on
+speculation. They were succeeded by a dogmatic materialism, which in its
+turn gave place to a sceptical positivism, or rather to a form of
+agnosticism. Granted the impossibility of belief in the immortality of
+the soul or in eternal life in any shape, the philosophy regarding death
+was reduced to the stoical idea that our end is in harmony with the laws
+of nature, and that it must therefore be accepted without protest.
+Resignation, therefore, in the fullest sense of the word, became the
+watchword of human wisdom.
+
+It was only to be expected that certain courageous and independent
+thinkers should not agree with this conclusion, and attempt to discover
+some other solution of the great problem absorbing mankind. Thence arose
+pessimism, the philosophic theory which became so prevalent during the
+last century, and which claims so many adherents in the present day.
+Pessimism, like belief in the immortality of the soul and the advocacy
+of resignation to the evils which beset humanity, is the product of the
+East, and India was probably its nursery. A pessimistic view of life is
+a salient feature of Brahminism, but Buddhism develops even more fully
+the doctrine that everything of this world is evil. That “life is made
+up of suffering” is the inexhaustible theme which, whether in the shape
+of philosophical argument, or in the more attractive form of poetry, the
+Buddhist Scriptures din ceaselessly in our ears.[212]
+
+In Europe, the lyrical poets introduced the pessimistic conception of
+the world, attracted by its emotional appeal. At the beginning of the
+nineteenth century, Byron struck this sad note, and expressed the view
+in the clearest fashion, that if we weighed our hours of joy against our
+days of pain, we should perceive clearly that whatever our life had been
+it were better not have been. In the following lines his conception of
+life is apparent:—
+
+       “Our life is a false nature,—’tis not in
+       The harmony of things, this hard decree,
+       This uneradicable taint of sin,
+       This boundless Upas, this all-blasting tree,
+
+       Whose root is earth, whose leaves and branches be
+       The skies, which rain their plagues on men like dew—
+       Disease, death, bondage—all the woes we see—
+       And, worse, the woes we see not—which throbs through
+       The immedicable soul, with heart-aches ever new.”
+                                                   “EUTHANASIA.”
+
+In chap. vi. I showed that Byron was haunted by a fear of death which
+ultimately led him to a recognition of the instinctive character of the
+feeling. He, however, like the other pessimistic poets (Leopardi), did
+not regard the world as being merely part of a universal system, and it
+was left to philosophy to come to this conclusion.
+
+During the first half of the nineteenth century, Schopenhauer
+endeavoured to give a presentation of a pessimistic theory, borrowed
+from Hindoo religions and from the views of contemporary poets, in the
+form of a rational philosophy. He developed a conception of life
+according to which “existence is to be regarded as something one is
+better without, as a kind of mistake which should be remedied when
+recognised.”[213] According to Schopenhauer existence is wrong, and
+results from the gratification of unrestrained desire. “If an attempt be
+made to realise the amount of misery, pain, and evil of all kinds, that
+the sun shines upon in its daily course, it will be seen how much better
+it would be were the earth to exhibit as few phenomena of life as the
+moon, and if the surface of the earth were in a similarly crystallised
+condition. Human life might equally be interpreted as a useless
+disturbance of the exquisite tranquillity of nothingness,” the meaning
+of the disturbance being wrapped in impenetrable mystery.[214]
+
+This melancholy state of life was the result of the cosmic process,
+which has created so much evil, and which finally evolved the human
+species, capable of feeling and appreciating to the full the pain of the
+world. The lower animals he regards as happier than man, their senses
+being less fully developed, and being unconscious of the worst aspects
+of their existence. In man, pleasure is purely a negation, whereas the
+sensation of pain is passive, contemplation, a human monopoly, rendering
+suffering still more unbearable. “Man’s capacity for pain increases far
+more with the passage of time than does his capacity for enjoyment, and
+is especially increased by his foreknowledge of death. Animals only fear
+death from instinct, without having any real knowledge of it, and
+without having the prospect of it always before their eyes, as is the
+case with human beings.”[215] Schopenhauer was convinced that happiness
+should not be regarded as the aim of life. “The greatest mistake we can
+make,” he said in his principal work,[216] “is to imagine that we are
+placed here to be happy.” “So long as we continue in this erroneous view
+which optimistic doctrines serve to foster, the world will continue to
+seem a mass of contradictions to us.” “It would be nearer the truth to
+regard pain as the aim of life rather than pleasure.” “The destiny of
+all human existence seems to be suffering. Life is wrapped about with
+evil, and cannot be protected from it. Life, at its very beginning, is
+signalised by tears, its course is fundamentally tragic, and still more
+tragic is its end. It is impossible to ignore that all this is meant to
+be.” “Death is the real goal of life. Its attainment brings a solution
+of all that has gone before.”
+
+The prospect and expectation of death, being products of reason, are
+experienced by men and not by animals. “Only in the case of humanity is
+the will capable of renouncing and withdrawing from life.”
+
+What is the answer to all these contradictions and the explanation of a
+cosmic process which on the one hand leads but to death, and on the
+other hand develops the intelligence so as to enable it to fear and
+dread the inevitable end? Is the solution to be found in belief in the
+immortality of the soul, supported as it is not only by nearly every
+form of religion, but by numerous systems of philosophy? Schopenhauer
+devotes many pages to the discussion of this question. He neither
+supports the doctrine of the resurrection of the body, nor the
+immortality of the conscious soul. “Just as the individual has no memory
+of prenatal existence, so after death he will remember nothing of his
+present life.”[217] “Those who regard birth as the actual beginning of
+man’s life must necessarily face death as final, the two being parallel.
+No man can therefore regard himself as immortal without forfeiting his
+belief in his own birth. Birth and death have the same origin and the
+same significance. They represent but one line, extending in opposite
+directions. If birth implies an origin from nothingness, then death must
+be complete annihilation.”[218]
+
+There is no such thing as individual immortality. But, according to
+Schopenhauer, to desire such immortality would merely be to advocate
+“the eternal perpetuation of a great mistake. Each individual existence
+is a definite mistake, a blunder, something that would better not have
+been, and the object of existence should be to end it.”[219]
+
+But if man, as an individual, is mortal, “death only takes away what was
+given by birth, that is to say, the principle by which death itself
+became possible.”[220] “Consciousness ceases at death, but the cause
+which produced that consciousness persists; life comes to an end, but
+not the principle which became manifest by life.”[221]
+
+What then is this immortal principle? It is the idea of the species or
+genus. Men or dogs, as individuals, perish in due course, but the human
+species or the canine species, the man “idea” or the dog “idea,”
+endures. Here Schopenhauer reverted to the conception of Spinoza, who,
+indeed, denied the immortality of the soul, but none the less believed
+in the immortality of the principle of life. This everlasting principle,
+according to Schopenhauer, is the will in its widest and most
+metaphysical sense, while, on the other hand, the mortal soul is the
+reason, a product of the functions of the brain.
+
+The eternal principle of life cannot be defined, because “we cannot pass
+outside the limits of our consciousness. And thus the problem of what it
+is in itself cannot be resolved.”[222]
+
+Schopenhauer himself recognises that this solution of the problem is not
+satisfactory from the point of view of those who desire reassurance of
+their immortality. “But,” he continues, “it is better than nothing, for
+those who dread death from the point of view of absolute annihilation
+should not despise the certainty of the persistence of the most vital
+principle of life.”[223] He further remarks that it must be remembered
+that nature is interested only in the preservation of the species, being
+indifferent to the individual. We ourselves being only a part of nature
+ought to further its plans. “If we wish to attain to a wider knowledge
+of nature, we must place ourselves more in sympathy with it, and regard
+life and death indifferently.”[224] Schopenhauer himself feels that his
+theories and arguments are unsatisfactory. When he had reached the full
+development of his doctrine, he admitted that it was negative in
+character, and that it ended in negation. It spoke only of what it had
+to deny and of what ought to be abandoned. It was obliged to regard as
+nothingness all that could be acquired in the future. As a consolation,
+he added that he meant relative nothingness, and not absolute
+nothingness.
+
+As an ultimate aim, there remained nothing but abrogation of the will to
+live, and thus misery and wretchedness, which are the inseparable
+accompaniments of human life, led to resignation.
+
+As our life is no more than a succession of misfortunes, and as,
+according to Schopenhauer, death is the plain conclusion of philosophy,
+the end of the individual life must be pleasant. As a general rule, he
+said, the death of a well-regulated life is calm and peaceful. But the
+privilege of dying willingly, with joy and delight, is reserved for him
+who has learned resignation, and has abolished and abandoned his will to
+live. For such an one would be willing to die in reality, not merely in
+appearance, and would neither desire nor claim a personal immortality.
+He would give up readily the existence that we know. Whatever may
+replace that existence is nothing from the point of view of
+individuality. The Buddhistic faith called the position attained by him
+who had given up the will to live, “Nirvâna, or nothingness.”[225]
+
+The natural deduction from this pessimistic doctrine of Schopenhauer
+would be to abolish the will to live by abolishing our individual life
+by suicide. But such is not the advice of the philosopher. He is far,
+however, from agreeing with those who regard suicide as criminal.[226]
+He merely does not admit that it solves the question. “He who commits
+suicide destroys the individual only, and not the species.” “Suicide is
+the voluntary destruction of a solitary phenomenon, without in the
+smallest degree affecting the system as a whole.”[227]
+
+The will to live manifesting itself, according to Schopenhauer, by the
+creation of new individuals, the philosopher would naturally, in
+accordance with his views of life, abstain from bringing others into the
+world. Schopenhauer lived and died a bachelor, and, so far as I am
+aware, had no children. On the other hand, convinced that the solution
+of life’s problem did not lie in suicide, he clung tenaciously to life.
+Having relinquished a belief in the immortality of the soul, he fell
+back upon a belief in the persistence of some ultimate principle, apart
+from conscious life, and held that in resignation and desire for
+annihilation (Nirvâna, according to his interpretation of the Buddhist
+doctrines) lay the true consolation for all the evils of human
+existence.
+
+For a long time Schopenhauer’s views found no echo in the opinions of
+other thinkers. Later, however, they became more and more widely
+diffused, and philosophic pessimism became quite fashionable. Those who
+did not adopt the metaphysical principles of Schopenhauer’s philosophy
+agreed with his views on life and on the impossibility of happiness.
+
+Exactly half a century after the publication of Schopenhauer’s principal
+work,[228] another German philosopher, E. Hartmann,[229] went a step
+further in the same direction. Without agreeing wholly with his
+metaphysics, he shared Schopenhauer’s views on the impossibility of
+regarding happiness as the true aim of existence. In order to
+demonstrate this theory, he examined the three phases of illusion
+through which mankind passes. He held that, in the first phase, people
+imagined happiness to be attainable during the present life. However,
+all that have been regarded as the sources of joy—youth, health, desire,
+conjugal love, family love, glory, etc.—end in disillusion. Love itself
+is especially submitted to Hartmann’s implacable criticism. According to
+him, there can be no question but that “love causes far more suffering
+than pleasure to those concerned.”[230] “It cannot be doubted,” he says,
+“that reason would prompt a total abstention from love,” and, as a means
+to this end, he recommends “the extinction of sexual desire by
+castration, if that could be relied upon to destroy desire.”[231] That,
+according to Hartmann, “is the only possible means of securing the
+happiness of the individual.” It is at the sacrifice of his personal
+happiness that man permits himself to love, and so abets the evolution
+of the cosmic process.
+
+“When they have become convinced of the impossibility of obtaining
+happiness in this world, people persuade themselves that it may be
+obtained after death in a transcendental life in another world. This,
+however, is only a second phase of illusion, and is based upon faith in
+life after death and eternity. It is certain, however, that the
+individuality of the organic body as well as that of the mind is only a
+delusion which ceases with death.”[232] Hartmann says in conclusion that
+“it is therefore plain that the hope of the immortality of the
+individual soul is also a mere illusion. And thus the chief support of
+the Christian promises is cut away; for men are devoted to their dear
+selves, and take little interest in a future happiness in which they
+themselves are to have no share.”[233]
+
+Being disillusioned regarding the possibility of obtaining happiness in
+this world, or in a future state, humanity falls back upon a third
+illusion. Firmly convinced that the aim of life is true happiness, man
+concluded that it was only attainable in some future state of the cosmic
+process. This hypothesis is based upon belief in a system of progressive
+development. “This,” declares Hartmann, “is yet another mistake.
+Humanity may progress as much as it likes,” he says, “but it will never
+succeed in suppressing or even diminishing the greatest evils which
+beset it: disease, old age, dependence on the wishes or the power of
+others, misery and discontent. Notwithstanding the new remedies which
+are discovered, the number of diseases, especially those of a chronic
+nature which are so trying, continues to increase at a rate that
+medicine cannot keep pace with. Joyous youth will always constitute a
+small portion of humanity, while the greater part will consist of
+melancholy old age.”[234]
+
+Against this idea that the happiness of the race will be the eventual
+result of progress, Hartmann employs the following arguments: “The
+happiest people are those who are the rudest and most primitive, and,
+among civilised races, the uneducated classes. It is well known that the
+progress of education increases discontent. The progress of science
+contributes little or nothing to the absolute happiness of the world.
+Practically speaking, this progress is of advantage to politics, social
+life, morality, and the arts; but factories, steam-boats, railways, and
+telegraphs, have so far done no positive good to humanity.”[235]
+Hartmann frequently recurs to the conclusion that the primitive are
+happier than the civilised, and that “the lower classes, inferior and
+rude, are happier than the rich who are well educated and great; that
+idiots are happier than the intelligent, and that, as a general rule,
+the less sensitive a man’s nervous system may be, the happier he is, as
+his capacity for feeling pain is not so much in excess of his capacity
+for enjoyment, and his illusion is therefore greater. With the
+progressive development of humanity, however, not only is there an
+increase in the extent of human needs, but in the sensitiveness of the
+nervous system, and in the cultivation of the mind. In consequence, the
+balance of pain over pleasure increases, and the illusion is destroyed,
+that is to say, knowledge comes of the misery of life, of the vanity of
+most of the pleasures. Misery itself increases as much as knowledge of
+misery, as experience has shown; and the apparent increase of happiness
+in the world, due to the progress of universe, is merely superficial.
+
+Having reached this extremely pessimistic conclusion, that it is
+impossible for humanity to attain happiness, Hartmann proceeds to
+inquire into the real destiny of man. He would be no true philosopher if
+he did not hold that the world was created according to a general plan,
+and that it follows a regular course tending towards a definite end. “We
+have seen,” he says, “how that in the present world all has been
+arranged in the wisest, and for the most part the best way, and that it
+should therefore be regarded as the best possible of worlds.
+Notwithstanding this, however, it is supremely miserable, and worse than
+if it did not exist at all.”
+
+Being convinced of the illusory nature of its hopes, humanity “must
+definitely renounce all pretensions to positive happiness, and aspire
+only to a freedom from pain, to annihilation or Nirvâna. This, however,
+must not be merely the attitude of solitary individuals, but humanity at
+large must cry out for annihilation. This is the only possible outcome
+of the third and last phase of illusion.”
+
+By what means is this end to be attained? Hartmann is no advocate of
+suicide as the best remedy of the evils of human existence. Upon this
+point he agrees with Schopenhauer, and thinks that such a course would
+have no effect upon the general progress of the cosmic process. A
+renunciation of pleasure—asceticism—would present no better solution of
+the problem. Even abstinence from reproduction would not serve the
+purpose. “What good would it do,” says Hartmann, “if humanity were to
+cease to be by means of sexual abstinence? This unfortunate universe
+would continue to exist, and the Unconscious would immediately take
+advantage of the opportunity to create a new man or some other similar
+type.”[236] Thus it is not the disappearance of mankind that should
+constitute our aim, but “the complete abandonment of the individual to
+the cosmic process, in order that the latter may accomplish its end and
+bring about the universal deliverance of the world.”[237] This being so,
+the instinctive love of life reasserts itself, and it becomes necessary
+to admit, at least as provisional truth, “the validity of the will to
+live; for it is only by complete resignation to life and its troubles,
+and not by cowardly renunciation and abandonment, that one may
+contribute one’s share in the development of the cosmic process.”[238]
+
+Hartmann’s proposed solution of the problem of human existence belongs
+undoubtedly to the category of systems advocating resignation. He is
+unable to tell us what is the cosmic process to which he bids man lend
+all his forces. He advises humanity to continue to live and to multiply
+in the full certainty that happiness cannot be attained. Hartmann
+obviously demands a true renunciation and an absolute submission. His
+solution has the appearance of being more exact, and of furnishing a
+guide to human conduct more clear than that vague aspiration to Nirvâna
+proposed by Schopenhauer. But on closer investigation it becomes at once
+plain that the greater precision is illusory.
+
+It is easy to see, under such circumstances, that a school of criticism
+or negation of the pessimistic doctrines should have gained many
+adherents. Very few, on the other hand, have embraced pessimistic
+doctrines because of any power being inherent in them to resolve the
+difficulties of life. A German pessimistic philosopher, Mailaender,[239]
+shared fully Schopenhauer’s opinions as to the misery of human life, but
+opposed the latter’s doctrine of resignation and Nirvâna as the solution
+of the general problem of life. Mailaender accepted the three stages of
+human illusion as expounded by Hartmann, but attacked vigorously the
+view of facilitating the cosmic process by acquiescence in the will to
+live. “Indeed,” he cried, “your advice is that we should sacrifice
+ourselves to the cosmos, we are to choose a career, to learn a trade,
+acquire money, property, fame, power, and so forth; we are to marry and
+to beget offspring; by such advice you are merely undoing with your own
+hands the sole merit of your work, the analysis of illusion. You
+suddenly advise the very man who has got behind all these illusions to
+succumb to them again, as if an illusion, although it has been
+recognised, could still deceive and exercise its power.”[240]
+
+Mailaender takes an entirely different view of the problem. Like his
+predecessors, he is convinced of the futility of happiness, but he has
+achieved an original view of the cosmic process. He holds that an
+unaccountable and divine Being existed before the creation of the world.
+Before disappearing “this divinity gave birth to the universe.” By this
+means, complete annihilation was made possible. “The world,” says
+Mailaender, “is but the means for bringing about a condition of
+non-existence, and is the only possible means by which that end could be
+attained. God knew that only by creating a real world could we pass from
+existence into non-existence.” Maileander regards as certain “that the
+universe tends towards universal non-existence.”[241] This tendency is
+characterised by the weakening of the total amount of energy, so that
+“every individual at the close of the weakening process to which his
+energy is submitted, is led in the course of his development to the
+point at which his desire for annihilation may be fulfilled.”[242] Life
+on our planet, he says, ought to be regarded as a halting-place on the
+road to death. In order to appreciate fully the happiness brought by
+death, it is necessary first to taste of life, and that is why the
+instinct of self-preservation is so well developed in animals. Man
+passes first through a phase of development in which he is like any
+other animal. “As with them, the will to live is stronger than the will
+to die. Life is clung to with extreme pertinacity, and death is
+proportionately execrated.” “At first, not only the fear of death
+increases, but equally the love of life.” Terror of death becomes
+acuter. Animals, knowing nothing of death, only fear it instinctively
+through their perception of approaching danger. Man, on the contrary,
+knows of the existence of death and what it means. He looks back on his
+past life and wonders what the future may hold in store, and realises,
+infinitely more than animals realise it, the dangers that threaten him.
+During this phase, man does all in his power to keep death at bay, and
+to make his life as happy as possible. This, however, is not the last
+stage of his development. The thinking man soon comes to the conclusion
+that a craving for life is not the true aim of the universe; it is only
+the means for attaining to a knowledge of the definite aim of existence,
+which is the cessation of life. Philosophy soon shows that perfect
+happiness is not possible, and that only death is really desirable. In
+summing up the cosmic process, the conclusion arrived at is “that
+throughout the universe the desire of death exists in a form more or
+less masked, but that in the organic world this assumes the form of a
+will to live.”[243] In the end, however, the desire of death becomes
+more and more plain, until the philosopher can see “in the whole
+universe nothing but a longing for absolute extinction, and fancies that
+he can hear the cry rolling from star to star, ‘Deliverance,
+deliverance, death to our life!’ and the echoing cry of consolation,
+‘Extinction and deliverance await you all!’”[244]
+
+In order to explain in a clearer way the progress of this evolution,
+Mailaender describes the state of mind of a man who develops the will to
+die, and commits suicide. “At first he glances anxiously and from afar
+at death, and shrinks from it with horror. Later, he draws nearer and
+walks round it in wide circles. Day by day, however, these circles
+become smaller, until finally he embraces Death with weary arms and
+looks it straight in the face. Then Peace comes; gentle Peace!”[245]
+
+It is absurd to expect anything to follow death but absolute
+annihilation, and the ordinary man faces this prospect with terror. “But
+it is essential,” says Mailaender, “that man should dominate the
+universe by knowledge, and wise men look forward to total annihilation
+with joy.”[246] “In relinquishing Schopenhauer’s will to live,”
+concluded Mailaender, “I have finally arrived at the will to die. I have
+raised myself upon the shoulders of Schopenhauer, until I have attained
+a point of view such as others have never accomplished. At present I am
+alone, but behind me all humanity is pressing on to freedom; and before
+me is the clear translucent vista of the future.”[247]
+
+I have quoted these views, not because of the solidity of Mailaender’s
+arguments, but merely because this pessimistic philosopher proved
+himself to be more consistent than his predecessors. While Schopenhauer
+and Hartmann, both so firmly convinced of the non-existence of happiness
+and the vast preponderance of suffering in all imaginable conditions of
+life, lived out their lives, Mailaender, true to his principles,
+committed suicide when barely thirty-five years of age.
+
+This is probably not a solitary instance. Under the influence of
+pessimism, a certain number of young persons, especially those whose
+mental equilibrium is not very firmly established, follow in the tragic
+footsteps of Mailaender. Some commit suicide, while others abstain from
+taking part in the perpetuation of the race. Others, but these are not
+many, curtail their existence by dissipation, thinking life not worth
+the care of it.
+
+A modern writer of great talent, Maeterlinck, echoes the pessimism of
+the present generation. “It is plain,” he says,[248] “that from one
+point of view humanity will always seem wretched, and as though being
+dragged towards a fatal precipice, since it will ever be doomed to
+disease, to the inconstancy of matter, to old age and to death.” “Yes,
+human life as a whole is sad, and it is easier, I may almost say
+pleasanter, to discuss and expose its dark side, than to enumerate its
+consolations and make the best of them. The miseries of life are many,
+obvious, and never failing; whereas the consolations, or rather the
+reasons which cause us to fulfil with alacrity the duty of living, are
+rare, hard to seek, and precarious.”
+
+Although pessimism has been greatly developed and widely spread during
+the nineteenth century, dissentient voices in opposition to this
+negative attitude towards the things of this world have not been
+wanting. Take the views of the German poet, Robert Hammerling,[249] who
+reproaches the pessimistic philosophers with ignoring the attitude of
+mind of the majority of mankind who ask but one thing,—life—life at any
+price and under any conditions. Against this sentiment all dogmatic
+arguments are useless, for, according to Hammerling, the question of
+pleasure and pain is a matter of feeling and not of reason. Now, with
+regard to the general feeling of humanity, there can be no doubt—it is
+frankly optimistic.
+
+Max Nordau, the well-known writer, supports a similar theory. According
+to him, all living nature betrays its optimistic foundation. “The truth
+is,” he says, “that optimism, limitless and irradicable optimism,
+constitutes the fundamental attitude of man, and is the instinctive
+feeling which governs him under all circumstances. All other forms of
+life confirm this truth....” “All nature,” according to Max Nordau, “by
+the bells of flowers and the throats of her birds, rings and proclaims
+the truth of optimism.” “No animals feel the pain of the world; and our
+own ancestor, the contemporary of the cave bear, was certainly free from
+all anxiety relating to the destiny of the human race.”
+
+These arguments do not take into account that, to be true, pessimism
+need not necessarily be felt and agreed with by all living creatures.
+Birds and other animals, happy in their lives, that is to say optimists,
+know nothing of the inevitability of death. Our cave ancestors knew
+nothing of it either. If the greater portion of modern humanity is
+optimistic, that might be accounted for by its being still under the
+influence of one of the three phases of illusion alluded to by Hartmann.
+It is only when the highest stage of development is reached that man,
+being convinced of the futility of his hopes, arrives at a pessimistic
+conception of the universe.
+
+Max Nordau disclaims discipleship of Doctor Pangloss, who held that the
+world is the best of all possible worlds. But his arguments reveal a
+pronounced optimism. He regards pain as an indispensable factor of the
+maintenance of life. “Without pain,” he says, “our lives would not
+endure an hour, for we should be unable to recognise dangerous symptoms
+and guard against them.” Insensibility to pain is often so grave a
+symptom that sick people rejoice when they are again able to feel the
+prick of a needle.
+
+This is true enough, but none the less the feeling of pain is very
+erratic in both animals and human beings. Quite insignificant causes and
+unimportant illnesses, such as certain forms of neuralgia, give rise to
+unbearable agony. A physiological phenomenon such as childbirth is often
+attended by extremely violent pain which is absolutely useless as a
+danger-signal. On the other hand, some of the most dangerous diseases,
+such as cancer or kidney disease, may exist for a long time without
+causing any sensation of pain, with the result that the sufferer knows
+nothing of the presence of the disease until it is too late. Were pain
+to play the part assigned to it by Nordau, it would appear in all cases
+of danger, and yet would never become almost unbearably acute.
+
+But when men have passed through the three stages of illusion it is not
+physical pain which presses most heavily on them. Max Nordau himself
+admits that it is “appalling to think of the cessation of our
+consciousness, and the annihilation of our ego.” None the less, he
+believes “that we are so happily constituted as to be able to accept the
+really inevitable with a light heart, and that there is no ill feeling
+about the matter.” This admission is not in accordance with the
+well-established facts discussed in chap. vi. With very rare exceptions
+man does not willingly accept the prospect of death, especially if he be
+still under the influence of illusion in any of its three stages. As a
+rule those who desire to live feel not only a repugnance to the
+contemplation of death, but death seems to them something abnormal and
+irrational. It is no answer to assert that all who feel this are
+psychopaths, or that it is absurd to think that the happiness of mankind
+counts for something in the cosmic process. On the contrary, it is quite
+natural that man should seek after happiness, and that he should try to
+analyse the phenomena taking place within him and around him from the
+point of view of that ideal. For this reason it is quite unjust to say
+that pessimism cannot be treated seriously. It is pessimism which has
+been the first to draw up a true indictment of human nature, and if pain
+is to be regarded as useful in its quality of danger-signal we should
+equally recognise that the pessimistic view of the universe is a step
+onwards in the evolution of humanity. Without pessimism we might easily
+sink into a kind of contented fatalism, and end in quietism, in the
+manner of many religions.
+
+It is only natural, however, that the thinking world should not accept
+pessimism as the last word of human wisdom, and that more or less noted
+philosophers should devote themselves to finding a possible solution of
+the problem of life and death. These systems of philosophy, one and all,
+have abandoned readily all belief in future life and personal
+immortality. But they have adopted pantheistic conceptions, and have
+accepted the existence of some general principle into which the
+individual consciousness will eventually be absorbed. There is division
+of opinion as to the properties of this principle. For some it is the
+Idea, for others Will, for others Force, or Eternal Energy.[250] The
+nomenclature is the less important as the views as to the nature of the
+general principle are absolutely vague. Accordingly this part of the
+philosophic doctrines appears in a lyrical form and has passed over into
+the domain of poetry.
+
+German poets have helped to spread pantheistic conceptions very widely.
+I need hardly mention Goethe, whose ideas were purely those of Spinoza,
+but Schiller’s well-known lines are precise:—
+
+   “Vor dem Tode erschrickst Du? Du wünschest, unsterblich zu leben?
+   Leb’ im Ganzen! Wenn du lange dahin bist, es bleibt!”
+
+   “Do you shrink from approaching Death? and crave immortality?
+   Live on in the All! Long after you vanish the All will remain!”
+
+Rückert, in lines almost equally well known, expresses the same idea:—
+
+
+           “Vernichtung weht dich an, so lang Du Einzles bist.
+           O, fühl’ im Ganzen dich, das unvernichtbar ist.”
+
+  “Annihilation fills you with terror, because you are self-centred. You
+  must feel your unity with the All, which is indestructible.”
+
+
+A volume might be filled with the attempts of thinkers of different
+countries to present these poetical ideas in a form less vague and more
+philosophical. I shall select only a few of the more modern instances.
+
+Renan’s[251] ideas may be taken as typical of the compromise between
+poetry and philosophy. Speaking of immortality, he said “that we shall
+each live again by the traces we leave on the bosom of the
+Infinite.”[252]
+
+The views elaborated by Guyau[253] are equally poetic. Like so many
+others he is unable to accept without protest the prospect of the
+inevitability of death. Brought face to face with this end, he declares
+that he feels “not sorrow but indignation, as against an injustice of
+nature.” “It is with justice,” he cries, “that we look on nature as a
+murderess if she kills what is morally best in ourselves and in
+others.”[254]
+
+It is chiefly in the name of love that Guyau protests against death:
+“The death of others, the annihilation of those we love, is
+insupportable to men, who are essentially thinking and loving
+creatures.”[255]
+
+This problem, so vast and so difficult to solve, is presented by him as
+follows: “As regards the question of individual immortality, human
+thought is dragged in opposite directions by two great forces—science,
+in the name of evolution, prepared to sacrifice the individual
+completely; love, in the name of an evolution, morally and socially
+higher, which would preserve the individual at all hazards. There is no
+more disturbing dilemma proposed to the philosopher.”[256]
+
+Guyau hopes that in the course of evolution there will come about a
+merging of individual consciousness in the consciousness of the whole.
+“One may ask,” he says, “if it may not be that these conscious entities
+mingling and interpenetrating, may come to live on from one to the
+other, and so to acquire a new duration?” On such a hypothesis he can
+foresee “an epoch not, indeed, certain to come, but far from
+inconceivable, in which individual consciousnesses will have achieved a
+corporate integrity and a complex intercommunion, without themselves
+being lost by the union.”[257]
+
+On this hypothesis, “the problem is to be at the same time loving enough
+and loved enough to live and endure in another.[258]... Those who vanish
+and those who remain must love one another so greatly that the shadows
+cast by them on the universal consciousness are identical.” “We should
+then feel ourselves passing and ascending from this life to an
+immortality of love,” and “the point of contact between life and
+immortality would be discovered.”[259]
+
+A solution recently offered by Finot[260] is much less poetical.
+According to him, it is only “when death is conceived of as annihilation
+that it is repugnant. On the other hand, if we regard it merely as a
+change of life, we shall cease to fear it, and even come to love
+it.”[261]
+
+But what is this “change of life” that is to prove so consoling? It is
+the “immortality of the body,” that is to say, the life of the creatures
+developed at the expense of the human body. “Flies begin the work of the
+labourers on the dead,” giving birth to worm-like larvæ that writhe in
+the decomposing flesh. The same vermin that horrified Tolstoi when he
+thought of his own death (see chap. vi. p. 123) became Finot’s symbol of
+consolation. He describes the whole succession of the fauna of corpses,
+and concludes by saying, “and so goes on the routine of life, from birth
+to the tomb, of noisy, clamorous life, ceaselessly renewed. Ever loving,
+giving birth, living and dying. The peace of the tomb is as filled with
+life as the dust into which we think our bodies will fall.”[262]
+
+I have given the above quotation as an instance showing to what lengths
+men have gone in their search for a solution of the problem of death and
+in their desire for a gleam of hope that the end may not be final. I
+need not say that this idea of the fauna of the corpse has no place in
+the philosophy of death. Thinkers, no doubt, would prefer the most vague
+ambiguities to certainties of such a nature. Most contemporary
+philosophers regard the problem in a very different fashion.
+
+In my opinion, Meyer-Benfey, a scholar at Göttingen, has summed up the
+present condition of the problem very clearly and exactly, in essays on
+Modern Religion.[263] He realises that it is impossible to accept the
+immortality of the soul. Personality must utterly and inevitably perish.
+But, just as no single atom of our bodies can be annihilated, so “no
+parts of our souls can be lost.” Our actions during life leave traces so
+much the deeper as the life has been fuller. It is this reuniting “of
+the actions of individuals with the life of the whole of humanity, that
+constitutes the true immortality or Nirvâna.” He says, too, “In
+accustoming our minds to this thought, and in educating ourselves with a
+view to the accomplishment of this end, lies the only possible means of
+overcoming the fear of death and the terror of annihilation.”
+
+Meyer-Benfey is of the pessimistic opinion that happiness cannot
+possibly be regarded as the supreme end of humanity, for he thinks, if
+that were so, the whole course of evolution would have been a mistake.
+It would have been much better had evolution been arrested before the
+creation of the human race, since animals, being unaware of the
+inevitability of death, are undoubtedly happier than man. As, however,
+we have passed through the animal stage and reached the human stage, and
+achieved some measure of civilisation, and this not by our own desire,
+or as the result of mere chance, but guided by the inner workings of our
+nature, it is plain that the ultimate goal towards which we are
+advancing, must be some other than mere happiness. There can be no
+question but that the goal is the triumph of pure and perfect culture.
+
+This idea, that the goal of humanity is progress in all its
+manifestations, is no recent theory, and many definitions of this
+progress have been advanced, but so far none have been generally
+accepted as satisfactory. The term “culture,” though vague, will have to
+continue in use until some better word conveying a more precise meaning
+is found to replace it.
+
+On reviewing all the systems of philosophy which have attempted so
+strenuously to solve the problem of individual death, it becomes plain
+that all, or nearly all, of them deny the existence of a future life and
+the immortality of the soul. The greater part of them, however, admit
+some general principle incomprehensible but eternal, which will
+eventually incorporate within itself all individual souls. Feeling that
+these vague ideas are incapable of conveying consolation to poor
+humanity in its fear of annihilation through death, philosophers have
+persistently taught the advantages of resignation. Even Guyau, realising
+that his philosophy regarding the immortality of love fails to reassure
+those who look to philosophy for some word of consolation, ends by
+admitting that “as there is no help to be expected from the inexorable,
+nor mercy from that which is in conformity with the universe and even
+with our own judgment, resignation is best.”[264] As it is the general
+opinion that to be philosophical is to take things as they are, without
+undue protest, the watchword of all systems of philosophy is to bow to
+the inevitable, that is to say, to be resigned to the prospect of
+annihilation.

+
+                               CHAPTER IX
+                  WHAT SCIENCE CAN DO AGAINST DISEASE
+
+
+  Formation of the experimental method—The intervention of
+  religion in disease—Disease as a basis of pessimistic systems of
+  philosophy—Advance of medical science in the war against
+  disease—The revolution in medicine and surgery due to the
+  discoveries of Pasteur—The beneficial results of Serum Therapy
+  in the war against infectious diseases—Failure of science to
+  cure tuberculosis and malignant tumours—Protests against the
+  advance of science—Opposition of Rousseau, Tolstoi, and
+  Brunetière—Proclamation of the fallibility of science—Return to
+  religion and mysticism
+
+
+Science, the youngest daughter of knowledge, has begun to investigate
+the great problems affecting humanity. The chief religions and many
+systems of philosophy had been long established before the spirit of
+scepticism dared to inquire whether or no these products of the human
+mind were really in harmony with fact. Scepticism gained ground little
+by little, and open war was declared between religious dogma and
+authority on the one side, and scientific reason on the other.
+
+The great religions and the philosophy of Aristotle had ruled a majority
+of mankind for some twenty centuries before doubt was cast on the real
+value of these doctrines.
+
+Francis Bacon, Lord Verulam, asked why it was that all the systems of
+his time were so vague and so powerless to explain the phenomena of the
+world. The cause could not lie in nature herself, for without doubt she
+followed laws that were immutable and that could be subjected to exact
+observation; nor could it lie in any want of intelligence in those men
+who devoted themselves to solve the problems. The true cause of the
+failure lay in the falsity or insufficiency of the methods employed.
+Bacon, trying to provide a remedy for this condition of affairs, advised
+that makers of generalisations should proceed very slowly, passing only
+by the smallest stages from particular facts to conclusions only more
+general in the slightest degree, and so on, until the ultimate formula
+might be reached. By such a path it was possible to attain principles
+neither vague nor ambiguous, but clear and exact and that would not be
+denied by nature herself.
+
+The first steps taken by science according to this method, which indeed
+had been suggested long ago, but which was first clearly laid down by
+Bacon, were slow and halting. Religious and philosophical doctrines
+still weighed heavily on inquiring minds, so that the new method was not
+followed with any great courage. None the less progress was achieved,
+until at length the great problems of humanity opened out. More than two
+thousand years before the birth of exact science, Buddha had given voice
+to the chief grievances of the human race. “Behold, O monks, the holy
+truth as to suffering,” he had proclaimed in the Sermon at Benares,
+“birth is suffering, old age is suffering, disease is suffering, and
+death is suffering.” Science, in its slow progress, passing from
+particular to general, reached first one of these four sorrows, the
+suffering due to disease.
+
+In the Buddhist legend that I quoted in chap. vi., the sight of a sick
+man “whose senses were weakened, who drew his breath with difficulty,
+whose limbs were shrivelled, whose bowels were wrung with pain, and his
+body pitifully soiled with excrement,” suggested to Buddha the
+reflection that “health is no more than the idle vision of a dream while
+fear and disease are horrible realities. What wise man, having seen the
+thing that life is, can still think of joy or of pleasure? Woe upon
+health which is assailed by so many maladies.” When Buddha, who was a
+young prince, asked of his father the gift “that he might always remain
+full of health, and that he should be smitten by no disease,” his
+father, who was the king, replied: “You ask me what is impossible; in
+that my son, I can do nothing.”
+
+From that day, every religion has busied itself with the cure and
+prevention of disease. They believed that the causes of these were the
+influence of evil spirits or the visitations of God; and as remedies
+they prescribed sacrifice and prayer and anything that might avert the
+anger of God. Even at the present day, similar medicine is used by
+primitive races. In Sumatra for instance, when it is impossible to
+arrest the flow of blood from a wound, the disaster is ascribed to an
+evil spirit (Polasièq) who is sucking the wound and making it incurable.
+In Nias, when bleeding from the nose occurs in children, it is supposed
+to be due to the father having killed a cock during the pregnancy of the
+mother. The indispensable remedy is to make sacrifice to the outraged
+deity.
+
+No doubt there co-exist with such practices of primitive races, certain
+useful rules, based on correct observation or on experience. It is a
+common practice to try all manner of remedies on the sick; although most
+do harm, now and again something useful may be discovered. Such vulgar
+medicine has undoubted merit, but it cannot be compared with the results
+of scientific medicine, which are drawn from rigorous experiment.
+
+Medical science has been slow in developing, but it has now reached a
+condition of which humanity may be proud. It is outside my purpose to
+give a long exposition of this subject; but it is necessary to my
+argument to set out a few facts from which the reader may judge of the
+present condition of medical science.
+
+Without doubt the fear of disease has played a large part in the
+pessimistic conceptions of the universe. Not only the words of Buddha
+that I have quoted, but many of the systems of pessimistic philosophy
+attest this. I have already stated in chap. vi. that Schopenhauer in
+1831 was driven from Berlin to Frankfurt by fear of cholera.
+
+In his statement of the case against this universe, and as a chief
+argument for his proposition that “this is the worst of possible worlds”
+Schopenhauer adduced the spreading of epidemics. “An alteration of the
+atmosphere so slight that it cannot be detected by chemistry brings
+about cholera, or yellow fever, or the black death, diseases which
+number their victims by millions; an alteration slightly greater might
+destroy all life.”[265]
+
+Hartmann, who has been one of the chief advocates of Schopenhauer’s
+pessimism, also had gloomy views on diseases and medicine. He was
+convinced that howsoever great the progress of humanity might come to
+be, there never would be an end or even a diminution of diseases. “It is
+no matter,” he said, “how many remedies may be discovered for diseases;
+new diseases, and particularly chronic affections which, although not
+serious are extremely painful, will continue to appear more rapidly than
+the discoveries of medicine.”[266]
+
+Humanity will be fortunate if the pessimistic philosophers prove as
+wrong about their other grievances as they have proved about disease and
+medicine. To understand the vast progress made by medicine, it is
+necessary only to compare the complaint of Schopenhauer with the actual
+state of affairs. When he spoke of epidemics being due to slight changes
+of the atmosphere, Schopenhauer obviously was repeating the medical
+opinion current in his times. Experimental science has proved that he
+was quite wrong. It has been shown conclusively that two of the great
+affections of which he spoke, cholera and plague, are due not to
+chemical changes in the air, but to definite microbes, the natural
+history of which is known as well as that of any other plant. Cholera is
+produced by the vibrio, discovered by Koch, a minute organism that lives
+in water and that enters the human alimentary canal with food or drink.
+We do not yet know a definite cure for cholera, but we do know how to
+prevent infection. The most simple mode of guarding against infection is
+to swallow only material that has been boiled, and to prevent
+contamination of water or of vessels with fæcal matter containing the
+Koch’s vibrio. Moreover, in individual cases use may be made of
+anti-cholera serums. In 1831, if these discoveries had been made,
+philosophy would have taken a different course. Instead of trembling at
+the epidemic, and flying to Frankfurt, Schopenhauer would have remained
+quietly at Berlin, and Hegel would not have ceased to develop his
+idealism in the university of that town.
+
+Schopenhauer enforced his argument by reference to the black death
+“capable of destroying millions of victims.” It is certain that the
+black death was no other than human plague, which made enormous ravages,
+in the fourteenth century, for instance, destroying nearly a third of
+the population of Europe. In those days, no one doubted but that it was
+a visitation of the Divine wrath, and people gathered in churches to
+make common supplication. Sacrifices were offered and flagellations took
+place in the hope of averting the terrible malady. Travellers who have
+been in the capital of Austria must have seen in one of the chief
+streets (Graben) a large and unlovely monument, erected in the
+seventeenth century to commemorate the interposition of Providence in
+staying one of the great epidemics of plague. Now that science has made
+known the true cause of plague, our ideas as to the causes of the
+appearance and disappearance of epidemics are very different. Plague is
+not the manifestation of the anger of God, but is a scourge due to
+invasion by a minute organism, discovered simultaneously by Kitasato and
+Yersin in 1894. The natural history of the microbe has been studied, and
+we know that it may live not only in human bodies but in the bodies of
+small rodents, such as rats and mice, which live in association with
+man. These animals are the source of human infection, and it is
+necessary to destroy them as completely as possible. There is no doubt
+but that the arrest of the plague in the seventeenth century was due to
+the fact that rats and mice had themselves been exterminated by the
+plague.
+
+Plague, which formerly was the most terrible of epidemic diseases, has
+now become a misfortune against which it is simple to guard ourselves.
+To secure that end, however, we have not to pray or to scourge
+ourselves, but to take measures to destroy rats and mice. Moreover
+serums may be employed; and the use of these is not only prophylactic,
+but if the disease be not too advanced, is actually curative. The danger
+of which Schopenhauer spoke may be regarded as definitely averted, and
+this is due to the advance of medical knowledge. In such countries as
+British India in which plague still causes great losses, we have to
+blame the ignorance of the population. Instead of following the course
+prescribed by science, these people still prefer the rules laid down by
+the Brahmanistic religion. Their idea of cleanliness and purity is a
+religious idea, and not that of medicine and bacteriology. It is not
+surprising that plague still exists in India, but none the less no case
+is a better instance of the progress of knowledge.
+
+Hartmann’s idea as to a progressive increase in the number of diseases
+rests on no exact grounds, and is in opposition to much that we know. As
+a matter of fact, as knowledge of hygiene advances and becomes spread
+among the peoples, diseases become less frequent and less fatal.
+
+A great stimulus was given to medicine and surgery when there was
+applied to these the knowledge gained by Pasteur in his study of
+fermentation. Pasteur showed that fermentations were chemical
+alterations in organic matter, excited by the presence of minute
+organisms very common in the neighbourhood of man.
+
+This discovery was applied in the first place to surgery. Lord Lister,
+then a surgeon in Scotland, showed that the festering of wounds was due
+to the entrance of minute organisms. Following this clue, he succeeded,
+by the use of dressings, in preventing the contamination of wounds and
+at once saw a vast reduction in deaths following surgical operations.
+Since the discovery of anæsthetics, such as ether, chloroform, and
+cocaine, and the use of germ-free dressings, surgery has been developed
+in a marvellous fashion. The varied and delicate feats of abdominal
+operation are known to all, and recently surgery of the heart has become
+possible.
+
+A comparison of the mortality of the wounded in the different wars of
+the nineteenth century affords an excellent means of gauging the
+progress of surgical treatment of gunshot wounds. The mortality of the
+wounded among the English troops in the Crimean war reached 15.21 per
+cent.; in the French troops in Italy in 1859–1860, it was 17.36 per
+cent.; in the German army in 1870–1871, the years in which antiseptic
+surgery came into use, it fell to 11.07 per cent.; while in the
+Spanish-American war in 1898, in the most brilliant period of modern
+surgery, the percentage mortality of wounded had fallen to 6.64.[267] In
+the recent Transvaal war, the mortality was half what it had been in the
+Franco-German war.[268]
+
+New medical knowledge, founded on the discovery of the nature of
+ferments and of the virus of infection, has reformed the practice of
+midwifery to such an extent that puerperal fever, formerly one of the
+great scourges of humanity, is now extremely rare.
+
+Blindness acquired at birth, which formerly rendered many lives
+extremely miserable, is now practically completely prevented, by means
+of the precautions taken to hinder the child from being contaminated by
+the mother in the process of birth. The most successful method is that
+which was suggested by Credé,[269] a German physician, and consists in
+placing in the pupils of the infant a minute drop of nitrate of silver,
+which is an antiseptic, and prevents the occurrence of ocular
+blennorrhagia.
+
+Appendicitis, a disease so common that I referred to it in chap. iv. as
+one of the most salient examples of disharmony in the human
+constitution, has been resolutely attacked by medical science. In some
+cases, surgical interference makes a definite end of the disease; in
+other cases medical treatment has been enough to subdue the symptoms
+without recourse to operation.
+
+For a considerable period, those of a sceptical disposition asserted
+that the advance of bacteriological knowledge was of service only in
+surgical cases. But Pasteur showed that this was an erroneous view.
+Working with Chamberland and Roux, Pasteur demonstrated that many
+infectious diseases could be prevented by the use of attenuated virus;
+he succeeded in saving the lives of many animals and of men, bitten by
+rabid dogs and affected by hydrophobia, a disease formerly almost
+invariably fatal and among the most horrible to which man is liable.
+
+In the latter direction, medical science is developing at an
+extraordinary rate, and is achieving results of a remarkable nature.
+Among recent discoveries, I may mention that of the curative properties
+of the blood serum of animals which have been subjected to the action
+either of microbes or of the soluble products of microbes. Von Behring,
+working with the Kitasato, a Japanese investigator, has shown that a
+serum of this nature, prepared with the poison produced by the microbe
+of diphtheria (the poison was discovered by Roux in collaboration with
+Yersin), is capable not only of protecting those in good health from
+diphtheria, but of curing those who have been attacked by the disease.
+The serum fails to act only when it is employed in advanced cases of
+diphtheria.
+
+Anti-diphtheritic serum, introduced into medical practice about eight
+years ago, has been tried in every way and has been proved to possess
+both preventive and curative properties. If patients still die from
+diphtheria, it is only because the treatment has been applied too late
+or insufficiently.
+
+The use of the anti-diphtheritic serum has reduced the mortality in
+cases of diphtheria from 50 or even 60 per cent. to 12 or 14 per cent.
+The number of infant lives that have been saved by this method must be
+enormous.
+
+The beneficent discovery of the curative value of serums has been
+applied to other diseases and is giving very encouraging results. I
+cannot go into details here, but it is enough to say that in the last
+quarter of a century medicine has entered a new epoch, and has taken its
+place among other exact sciences based on the experimental method.
+Although it is not surprising that in so short a space of time science
+has not yet conquered all the ills affecting humanity, this failure has
+provoked the most severe criticism.
+
+“Indeed,” one of the critics has said, “you vaunt the progress of
+medical science at a time when you have to confess that it has failed to
+cure tuberculosis, one of the gravest of the infectious diseases, which
+alone causes the death of a sixth part of the human race.” It is true
+that the infectious nature of this scourge was announced by Villemin
+more than forty years ago. Twenty years have passed since Koch, the
+German bacteriologist, discovered the microbe that produces not only the
+ordinary form of pulmonary consumption but all other varieties of
+tuberculosis. And we are still ignorant of any remedy for the disease.
+In all the bacteriological institutes and laboratories search is being
+made for some vaccine or serum or medicament which will arrest a disease
+that in many cases nature herself cures. But the results amount
+practically to nothing.
+
+This is certainly a good example of the failure of science. None the
+less a closer examination shows that even with the knowledge already
+gained we could deal with tuberculosis in a manner more efficacious than
+is the existing practice. When the infectious nature of the disease had
+been made known, before waiting for the discovery by Koch of the actual
+bacillus, we should have employed all the known modes of destroying
+infectious matter. In spite of all that has been said and written on the
+subject, people still spit on the floors of omnibuses and cars and on
+street pavements. Tuberculosis is propagated not because of the failure
+of science, but because of the ignorance and stupidity of the
+population. To diminish the spread of tuberculosis, of typhoid fever, of
+dysentery, and of many other diseases, it is necessary only to follow
+the rules of scientific hygiene, without waiting for specific remedies.
+
+Although the science of to-day is sufficiently armed against the
+diseases commonly known as infectious, the case is very different with
+some other affections, among which the chief place is taken by malignant
+tumours, or cancers, in the most general sense of the word.
+
+There are few maladies more terrible, for they practically never
+disappear spontaneously, and surgery can remove them successfully only
+if they have been recognised at an early stage. Every year a number of
+persons, old and young, die victims of malignant tumours, and it is even
+possible that cancer is more prevalent now than in former times. It has
+been suggested that the increase of cancer is due to the greater
+longevity among modern races, and as malignant tumours are most common
+in old persons, it may well be that the prolongation of life has given
+this disease a larger field. However, even allowing for this, it is
+probable that there is a real increase of cancer.
+
+Unquestionably the malignant tumours are the diseases most disappointing
+to medicine and surgery, and these sciences are as much at a loss with
+regard to them as in the case of infectious diseases before the
+discovery of pathogenic organisms. Science is perhaps even in worse case
+with regard to cancer than it formerly was with regard to infectious
+diseases, for, before the discovery of microbes, something was known of
+the virus which produces infection. Thus the virus of smallpox was
+known, and was used, by the method of inoculation, to prevent more
+serious attacks of the disease. Nearly a century before the discoveries
+of Pasteur, Jenner had been able to be of the greatest service to
+mankind by his discovery that the virus of cow-pox could be used as a
+preventive of infection by smallpox.
+
+In the case of malignant tumours, we do not even know their real nature;
+we are ignorant as to whether or no they are infectious, and whether
+they are caused by a microbe coming from without or are due to internal
+changes of the tissues. Our ignorance, however, affords no ground for
+despair. It is probable that the malignant tumours will soon come to be
+ranged with infectious diseases due to invasions by specific microbes.
+Experiments on the cancers in rats and mice have shown that these can be
+inoculated in the same manner as in the case of the recognised
+infectious diseases. Hanau has shown that this occurs in the case of
+epithelioma of old rats; Morau[270] has succeeded in transferring the
+cancers of white mice, and his results have been confirmed by
+Jensen[271] and Borr[272], in the Institut Pasteur. These
+investigations mark the beginning of a new stage in the knowledge of
+tumours. I am unable to see, therefore that the malignant tumours
+provide a satisfactory argument in favour of a pessimistic conception of
+the universe.
+
+Dr. Boas, of Berlin,[273] in a recent publication, has laid stress on
+the fact that most patients affected with cancer do not seek medical aid
+until the disease is far advanced. For instance, in 80 per cent. of the
+cases of cancer of the rectum that he had attended, the patients
+presented themselves too late for operation. Boas advised that the
+attention of the public should be drawn, by means of widespread
+publication, to the earliest symptoms of cancerous disease. He thought
+that such a course might save many lives by making possible operation in
+early stages.
+
+The prevention and treatment of disease, which for long was in the hands
+of religious authorities, is now passing into the care of those who
+employ the methods of scientific medicine. It is now only in the case of
+certain nervous maladies, which can be treated by suggestion, that
+religion has any important part to play. I have not thought it necessary
+to expound at length the work of science in the struggle against
+disease, because the evidence on this point is extremely clear and
+precise. Every one must accept it, and even the passionate enemies of
+science have to bow before the fact.
+
+However, the problem has been changed. Science they now admit, is
+capable, no doubt, of assuaging humanity in its sufferings from this or
+the other disease. But there is another question. Disease is only an
+episode in human life, and the great problems remain unsolved by
+science. It is not enough to cure a man of diphtheria or intermittent
+fever; it is necessary to explain what the destiny of man is, and why he
+must grow old and die at a time when his desire to live is strongest.
+Here, plainly, all science must fail, and here must begin the beneficent
+work of religion and philosophy. But as science is constantly casting
+doubt on the dogmas of religion, and criticising adversely the systems
+of philosophy, it is plain, that so far from being of service, science
+is actually harmful to mankind.
+
+The campaign against science was opened long ago. In the eighteenth
+century Rousseau[274] opened it with brilliancy and zest worthy of his
+reputation. He defended his theme with vigour and eloquence and the
+following quotations may serve as an example, “Know O people,” he wrote,
+“that nature has desired to preserve you from science as a mother tries
+to snatch a dangerous weapon from the hands of her child; that the
+secrets which she has hidden from you are evils from which she would
+preserve you, and that one of her greatest gifts is the difficulty with
+which knowledge is acquired. Human beings are perverse, but they would
+have been worse had they had the misfortune to be born learned men.[275]
+Our sciences are futile in so far as they fail to attain their objects,
+but they are worse than futile in the results that they bring about.
+Born of idleness, they cherish their mother—Tell me, illustrious
+philosophers, you from whom we know why matter attracts matter, the
+relations of the orbits traced by revolving planets, the mathematical
+properties of curves, what stars may be inhabited, what insects exhibit
+curious modes of reproduction; tell me, I say, you from whom we have
+gained such marvellous information, if you had never learned of these
+things, should we have been less numerous, less well governed, less
+flourishing, or worse disposed?”[276]
+
+Such words were capable of impressing men because of their eloquence and
+sincerity, but they could not arrest the continued and triumphant
+advance of science, which indeed, precisely at the end of the eighteenth
+century, began its modern and lasting progress. For it was then that
+Laplace described the system of the heavens and that Lavoisier laid the
+foundation of modern chemistry and of our knowledge of the
+indestructibility of matter.
+
+In the nineteenth century, science has made a revolution in life by its
+application of steam and by its other triumphs. None the less it has not
+satisfied many distinguished persons. And to-day we find a writer of
+genius, in the manner of Rousseau, raising his voice against the science
+of the nineteenth century.
+
+Tolstoi, in an essay of which the title is, “On the Aim of Science and
+Art,” has attempted to show the incompetence of science with regard to
+the great problems that occupy humanity. The task set himself by the
+Russian writer was much harder than that of Rousseau, for with the
+passing of a century science has become much more powerful.
+
+Tolstoi is convinced that theoretical investigations into the origin of
+life, the intimate structure of living matter and so forth, are of no
+importance to human beings, and serve no other purpose than to flatter
+the pretensions of the learned. “All that we call culture,” he affirmed,
+“our sciences, our arts, improvements in the amenity of life, are no
+other than attempts to deceive the moral cravings of mankind; all that
+we call hygiene and medicine are no other than attempts to deceive the
+physical and natural cravings of mankind.”[277]
+
+The whole progress of science “up to the present time, has not only not
+improved the lot of the majority of mankind, that is to say of the
+labourers, but has made it worse.”[278]
+
+Tolstoi thinks that the epithet “true science” could be given only to
+“knowledge of the right aim and true happiness of each individual and of
+mankind as a whole. Such a science would serve as a guiding thread in
+determining the proper sphere of all knowledge”; “without knowledge of
+the proper aim of life and of the real good of humanity, all other
+knowledge and every art become merely amusements idle or even
+harmful.”[279]
+
+The chief grievance of the great Russian writer against knowledge,
+culture, and progress can be resolved into the powerlessness of these to
+explain the most difficult problems of humanity, that is to say the real
+aim of human life, and what really constitutes true happiness.
+
+In this connection, Tolstoi gives expression to a view which is shared
+by many thinkers. Some years later, Brunetière,[280] a well-known French
+writer and public man, under the influence of a recent journey to Rome
+and visit to the Pope, made public a similar opinion, and proclaimed
+aloud the fallibility of science.
+
+Brunetière made his criticism as follows: “For the last two or three
+centuries, science has promised to change the face of the earth, to
+dispel every mystery; she has not done so. She is powerless to resolve
+the sole problems that are essential, that concern the origin of man,
+the rules for his conduct, and his future destiny. We know now that
+natural science can teach us none of these matters. Thus, in the battle
+between science and religion, science has been defeated, because she has
+had to admit her powerlessness precisely where religion is most strong.
+For religion gives the solutions that science has failed to supply.
+Religion teaches us what we can learn neither from anatomy nor from
+physiology, that is to say, what we are, whither we are going, and how
+we ought to act. Religion and science supplement each other; and, as
+science can do nothing for morality, it becomes the duty of religion to
+take her place.”
+
+It has been replied to Brunetière, that his recriminations are
+unfounded, first, because science has never undertaken to solve the
+great problems of the aim of life and the proper basis of morality;
+next, because it is probable that these problems will never be solved by
+the human understanding. Charles Richet, a well-known French
+physiologist, made a vain effort to find any written evidence that
+science had promised to solve the great problems which have absorbed the
+attention of Tolstoi and Brunetière as well as of quite a large section
+of humanity. “In what standard works has science made the astonishing
+promises that M. Brunetière recalls with so much bitterness?” asked
+Richet.[281] “I have now before me,” he proceeded, “the Manuel du
+baccalauréat ès sciences (Guide to a Degree in Science). It is a summary
+of contemporary scientific ideas. I have looked through it in vain for
+promises—it contains no promises.”[282]
+
+The promises referred to must be looked for in scientific treatises that
+deal in generalisations. It is not to be disputed that, since the
+renaissance in Europe of the rational and sceptical spirit, that is to
+say, in the last two or three centuries, the view has been proclaimed
+that all human life may be regulated by natural laws without the
+interposition of dogmas, either metaphysical or religious. Attempts of
+this kind have been numerous. Büchner, in his treatise on “Force and
+Matter,” in which he tried to give a general conception of the universe
+based on the scientific knowledge of the nineteenth century, made very
+plain statements on this point. “We must seek the foundation of
+morality,” said the German populariser, “elsewhere than in the timeworn
+and fantastic belief in the supernatural. Science must replace religion;
+belief in the real existence of a natural and immutable order in things
+must displace belief in spirits and ghosts; natural moral law must take
+the place of artificial or dogmatic morality.”[283] Büchner even tried
+to indicate what natural morality is. According to him it is “the law of
+mutual consideration of the equal rights of each person, both from the
+general and the individual point of view, so as to assure the greatest
+happiness of the greatest number. Everything that damages or destroys
+the common good is ‘evil;’ everything that favours it is ‘good.’”
+
+The other question, as to whither we are going, finds an answer in the
+materialistic and scientific breviary of Büchner. He disputes the idea
+of immortality, which has been supported by nearly all the religions,
+and comes to the conclusion that there is nothing appalling to a man,
+“imbued with the principles of philosophy, in the conception of the
+annihilation of the individual life.” “Annihilation is perfect rest; it
+is freedom from all pain and escape from the sensations that torture the
+body and the mind—as was explained so clearly in the great religion of
+Buddha; it is not to be feared, but rather to be coveted when life has
+reached its normal term and when old age has come with its inevitable
+assemblage of infirmities.”
+
+I do not wish to suggest that the views I have just quoted are peculiar
+to Büchner. That writer has served to a large extent as the mouthpiece
+of ideas current among the materialistic and positivist men of science
+of his time. In Haeckel’s book, “The Riddle of the Universe,” which
+appeared nearly half a century after the first edition of “Force and
+Matter,” the same ideas are to be found. He also has found answers to
+the questions that absorb mankind. In his opinion also, as I have shown
+in chap. v. the problem of natural morality resolves itself into the
+social instincts of man, and has nothing to do with religious dogma. As
+for the destiny of man, he concludes as follows: “The best end we can
+desire after a courageous life, spent in doing good according to our
+light, is the eternal peace of the grave.”[284]
+
+There is a very close resemblance between the views of the two great
+popularisers of the nineteenth century. Just as Büchner, to show the
+stupidity of the idea of eternal life, repeated the legend of the
+“Wandering Jew,” so Haeckel, with the same object, related the legend of
+the unhappy “Ahasuerus” who sought death vainly, finding his eternal
+life intolerable. “However gloriously we may depict this eternal life in
+paradise, in the end it would be a fearful burden to the best of men.”
+
+While there is no doubt but that such ideas are shared by many men who
+rely on scientific arguments, there are others to whom the problem
+presents itself differently. The German physiologist, Du Bois Reymond,
+after reflecting on the general problems of knowledge and the universe,
+proclaimed an “Ignorabimus” as a warning that a whole series of problems
+of the highest importance to humanity were outside the range of human
+knowledge and incapable of solution. These problems were precisely the
+seven “riddles of the universe” that Haeckel claimed to have solved in
+his book.
+
+Many learned men think that the great problems, those, according to
+Tolstoi, that constitute the only true science, can never be solved.
+“Every day there comes a new conquest,” said Richet,[285] “but we are no
+nearer solution of the ultimate enigma, the destiny of human life, an
+enigma probably never to be solved.” Philosophers have taken the same
+view. “It cannot be from science,” said Guyau, “that personality is to
+require the proofs of its own durability.”[286]
+
+The answers given by science as it exists to-day, have failed to console
+the spirits that have applied to her. When Richet, in the discussion on
+the “bankruptcy of science” recalled the discovery of treatment of
+diphtheria by specific serums as an instance of the value of scientific
+research, Brunetière replied, “Serum therapy cannot prevent us from
+dying, nor tell us why we must die.” The problem of death always recurs.
+What is the use of saving the life of a child smitten by diphtheria only
+that it may grow up, and by learning the inevitability of death become
+filled with terror?
+
+If science be really powerless before the gravest problems that torture
+mankind, if she has to excuse herself by admitting her incompetence, if
+she can do no better than to extol the silent annihilation of the grave,
+it is not surprising that many minds and these not the least capable,
+turn from her. The desire to find some consolation in the miseries of a
+purposeless existence throws them into the arms of religion or
+metaphysics. Here lies the explanation of the actual return in these
+days to faith. People plunge into mysticism hoping to find there
+something more comforting than the annihilation offered by science.
+
+In all ranks of modern society there are signs of this craving for the
+supernatural. It is therefore extremely interesting to follow the
+intimate steps of such an abandonment of science and return to faith.
+The “Confessions” of Tolstoi gave one of the best examples of the
+metamorphosis.
+
+Having reached the conclusion that life is meaningless because it cannot
+be harmonised with the fear of death and the prospect of absolute
+annihilation, Tolstoi (see chap. vi.) asked if it were not possible to
+solve the great problem of human existence by means of the facts of
+science. “I searched in all the sciences,” he said, “and not only found
+nothing myself, but became convinced that all who sought would find
+nothing. Not only would they find nothing, but they would see clearly
+precisely what had driven me to despair, the fact that the absurdity of
+life is the sole indisputable bit of knowledge open to man.” “For a long
+time, observing the grave and solemn tones of the exact sciences, which
+indeed, hardly touched the problem of life, it seemed to me that they
+must be concealing something that I did not understand.”
+
+All the while, the question that Tolstoi put to himself seemed simple
+enough: “Why am I to keep alive? Why am I to do anything?” or, in
+another way: “Has life any object that is not destroyed by the
+inevitable death that awaits me? To the one question, put in many ways,
+I sought an answer in human knowledge.” “From my earliest youth the
+speculative sciences interested me deeply. Later on, the mathematical
+and physical sciences attracted me, and until my question rose up
+clearly before me, day by day growing larger, and imperatively demanding
+an answer, until then I was satisfied with the semblance of an answer
+given by science.” “I said to myself; everything is evolving,
+differentiating, moving towards complexity and amelioration, and the
+progress is under the guidance of law. You, you yourself are part of
+this whole.” “Although I am deeply ashamed to confess it, there was a
+time when I thought myself content with these things. My muscles grew
+and became stronger. My memory added to its stores. My ability for
+thinking and understanding increased. I grew and developed, and feeling
+the growth within me, it seemed natural to believe that the solution of
+my own life was given by the law of the whole universe. But the time
+came when I stopped growing. I felt that I was no longer developing and
+even that I was slipping back. My muscles weakened; my teeth dropped
+out; and I felt that this law not only explained nothing, not only had
+never explained anything, but had not been a law at all; that in fact I
+had taken for a law what I found in myself at a particular stage of my
+life.”
+
+“As I found no explanation in science,” Tolstoi went on, in his poignant
+narrative, “I began to look for the answer in life, hoping to find it in
+the men around me.” “My intellect was at work, but also something else,
+something that I can call only the consciousness of life, like some
+strong force that compelled my intellect to turn in another direction
+and to rescue me from my desperate condition.”
+
+The new direction was the feeling of faith. “However I might put to
+myself the question: how must I live? the answer was—by the law of God.
+Whither tends my present life? To eternal pain or to blessedness
+everlasting. How is my life not destroyed by death? By eternal union
+with God, by heaven. And thus I was led inevitably to see that quite
+independently of human knowledge, which formerly seemed to me the only
+guide, mankind had another guide, a guide that is irrational; faith
+which makes life possible. Faith seemed to be as irrational as ever, but
+I could not but recognise that faith alone gave mankind an answer to the
+problem of life, and in consequence made life possible. Reason had led
+me to the conviction that life was absurd, and so, there being no longer
+a reason to live, I had wished to kill myself. Looking at mankind as a
+whole, I saw that men kept alive by assuring themselves that they saw a
+meaning in life. I myself came back to that point of view. I had reached
+a time when there seemed to me to be no meaning in life. But as to other
+men, so to me, life and the possibility of living were offered by
+faith.”
+
+Driven in the direction of faith, Tolstoi reached the following
+conclusion: “The object of a man’s life is the salvation of his soul;
+for that, we must live in God, and to live in God it is necessary to
+give up the pleasures of life, to work, to submit, to suffer and to be
+charitable.” And this conclusion led to the other that “a faith has
+value in so far as it gives a meaning to life which is not destroyed by
+death.”
+
+It is plain then that all this evolution, the beginning of which was the
+fear of death, ended in belief in something beyond death. And it is also
+plain why Tolstoi should have been as bitter against science as I have
+shown him to be. Tolstoi does not afford the only example of a case
+where the failure of science to solve the problem of death has led to
+the abandonment of science in favour of religion. Brunetière, if it is
+possible to judge from his published writings, traversed similar paths
+in his journey to the Catholic religion.
+
+However, even an intellect so positive and so sceptical as that of Zola
+has been unable to resist the lures of faith. There is a very
+interesting note on this subject in the _Journal_ of de Goncourt, dated
+February 20, 1883. “To-night, after dinner, at the foot of the bedstead
+of carved wood, where coffee was served, Zola began to talk of death, on
+which his thoughts have been fixed more than ever since the death of his
+mother. After a short silence, he said that death had made an in-road on
+the nihilism of his religious convictions, as he could not face the
+possibility of an eternal separation.”
+
+In strata of society less impregnated with rational and scientific
+thought, it is plain that the return to religion must be more common. I
+recall the case of a woman of the people, a workwoman, who declared that
+she formerly had had no belief, but that, since the birth of her son,
+she had begun to believe in the good God, as she was convinced that it
+was only by such a belief that she could guard the life of her child
+from the evils of the world.
+
+As things are, it is not wonderful that many people decline to educate
+their children in an exclusively scientific spirit, which is destructive
+to faith, as they cannot substitute for faith something equally
+consoling. Perhaps ideas of this kind lie behind the story of the apple
+of the Garden of Eden and the invention of the words of Jahveh: “But of
+the tree of the knowledge of good and evil, thou shalt not eat of it:
+for in the day that thou eatest thereof thou shalt surely die” (Genesis
+ii. 17). The legend of Prometheus, who stole fire from heaven, and was
+chained to a rock, is in the same category.
+
+Solomon gave voice to the same idea, in the clearest way, in his words:
+“I communed with mine own heart, saying, Lo, I am come to great estate,
+and have gotten more wisdom than all they that have been before me in
+Jerusalem; yea, my heart had great experience of wisdom and knowledge.
+
+“And I gave my heart to know wisdom, and to know madness and folly: I
+perceived that this also is vexation of spirit.
+
+“For in much wisdom is much grief: and he that increaseth knowledge,
+increaseth sorrow” (Ecclesiastes, i. 16).
+
+Much later, Shakespeare offered to us in _Hamlet_, the type of a man
+very highly cultivated, in whom reason and reflection had arrested
+action. As he could not solve by reason the problems that haunted him,
+he asked if it were worth while to remain alive. Then followed the
+famous lines:
+
+            “Thus conscience does make cowards of us all,
+            And thus the native hue of resolution
+            Is sicklied o’er with the pale cast of thought.”
+
+As so many men of genius have taken the same point of view, it becomes
+necessary to inquire carefully as to whether or no too much knowledge be
+harmful to human happiness. If science do no more than to destroy faith
+and to teach us that the whole living world is moving towards a
+knowledge of inevitable old age and death, it becomes necessary to ask
+if the perilous march of science should not be stayed. Is it that the
+attraction of mankind to knowledge is as dangerous to the race, as the
+attraction of moths to the light is fatal to these wretched insects? The
+question demands an exact answer. But before giving the verdict, the
+facts of the case must be examined. I shall proceed to this in the
+chapters to follow.
+
+
+
+
+                               CHAPTER X
+            INTRODUCTION TO THE SCIENTIFIC STUDY OF OLD AGE
+
+
+  General account of old age—Theory of senile degeneration amongst
+  unicellular organisms—Conjugation amongst infusoria—Old age in
+  birds and anthropoid apes—General characters of senile
+  degeneration—Sclerosis of the organs—Phagocyte theory of senile
+  degeneration—Destruction of higher elements by macrophags—Mechanism of
+  whitening of the hair—Serums acting on cells (cytotoxins)—Sclerosis of
+  the arteries and its causation—Harm done by the microbes of the
+  alimentary canal—Intestinal putrefaction and the modes of preventing
+  it—Attempts to prolong human life—Longevity in biblical times
+
+
+While I cannot share the views of those who turn from science to seek
+truth and consolation in religion, it would be wrong to ignore or to be
+indifferent to the existence of that attitude. There are men who are
+tormented by the contradiction between the desire of life and the
+inevitability of death, and when these demand some solution of the
+problem, it is unreasonable merely to say that they are too exacting and
+should learn contentment.
+
+If a man complains to his physician of uncontrollable hunger and thirst,
+he is not told that it is wrong to be so greedy, and that that fault
+could be mastered by strength of mind. The doctor carefully examines the
+patient and does what he can for the distressing symptoms, which,
+indeed, in this case are generally due to diabetes. Those who hunger and
+thirst after eternal life, ought to be similarly treated by men of
+science whose duty it is to ameliorate their sufferings as much as
+possible.
+
+Science has undoubtedly gone far in the successful treatment of disease,
+both as regards prevention and cure, but it is powerless before those
+other evils from which Buddha implored his father to grant him
+exemption—old age and death. Science has attained to heights of
+knowledge undreamed of by Buddha’s father, King Couddhôdana, and yet it
+knows no more than he did with regard to the problem of old age and
+death. Like the king, science can but reply to its questioners: “You ask
+the impossible. I cannot help you!”
+
+Not only is no remedy for old age known to science, but little or
+nothing is known with regard to that period in the lives of men and
+animals. It was no easy task to compress an account of the present
+position of medicine within a few pages, the subject matter being
+overwhelming in quantity. With regard to old age it is quite the
+contrary, our knowledge being so limited that the subject may be dealt
+with in a few lines. With the advance of years, man and the higher
+animals undergo important modifications. They become weaker, the body
+shrinks, the hair whitens, and the teeth decay; in fact, all the
+phenomena connected with senile decay manifest themselves.
+
+At this period of life which overtakes various species of animals at
+different ages, the body becomes an easy prey to pernicious influences
+and diseases. The direct cause of death cannot always be determined, and
+is attributed to the general breaking up of the system which we call
+natural death. The first question which presents itself to the
+scientific mind is whether this degeneration or senile decay is proper
+only to man and the higher animals, or is common to all forms of life.
+We have all seen very old trees, the appearance of which proclaims their
+age. The trunk is decayed, the bark gnarled, the branches shrivelled,
+and the leaves scanty. Some kinds of trees live for hundreds—possibly
+thousands—of years, while others age with comparative rapidity. Senile
+decay is not unknown in the vegetable kingdom, and its presence is
+suspected even among creatures of very simple organisation belonging to
+the group of infusoria. These creatures may be reared with ease in
+vessels containing macerations of chopped hay or leaves. They multiply
+by means of division (Fig. 12), an operation which takes place at very
+short intervals, some of them dividing nearly every hour. Owing to this
+rapid multiplication the vessels soon become full of a mass of
+infusoria. M. Maupas,[287] a very distinguished zoologist, observed that
+the infusoria became smaller and smaller after a number of generations,
+exhausting themselves, as it were, and perishing unless two individuals
+succeed in uniting. This process of “conjugation” (Fig. 13), involves an
+exchange of portions of the bodies of the two creatures and brings about
+a complete rejuvenescence of the two individuals. After conjugation, a
+process essentially similar to the details of sexual fertilisation, the
+infusoria resume the normal appearance and again become capable of
+reproduction by simple division for many generations.
+
+[Illustration:
+
+  FIG. 12. Paramecium about to divide in two.
+]
+
+The periodical debility, which precedes conjugation is, according to
+Maupas, an instance of senile degeneration among infusoria. He has
+recognised its existence in the case of many species of the higher
+infusoria (_Ciliata_), but while this phenomenon has been observed in
+the case of many other simple organisms, it cannot be set down as
+universal among microscopic beings. Among bacteria, a group that
+includes the greater number of pathogenic organisms, conjugation has
+been very rarely observed. Even the largest kinds, such as, for
+instance, the _anthrax_ bacillus, may be propagated for a long series of
+generations without the occurrence of conjugation.
+
+[Illustration:
+
+  FIG. 13. Conjugation of two Paramecia (after Bütschli).
+]
+
+Even in the case of the infusoria which by means of the process of
+conjugation can reproduce indefinitely, the preconjugal debility cannot
+be identified with the senile degeneration of human beings, the higher
+animals and trees. In all these debility is the antecedent, not of
+conjugation and rejuvenescence, but of the end of life.
+
+Another important difference is that in the case of infusoria the
+preconjugal debility does not occur in every individual, as is the case
+with the animals and plants which display real old age. In the infusoria
+an indefinite number of generations occur between the individuals that
+display debility and those that are ready for conjugation.
+
+If, in spite of these differences, we were to insist on the existence of
+an essential resemblance between senile degeneration in man and
+preconjugal debility in infusoria, it would be enough to reflect on the
+result of applying to the case of man what is an infallible remedy in
+the case of the infusoria. For conjugation brings about a real
+rejuvenescence of the infusoria and a similar event in the case of man
+would only increase the debility. Moreover, according to recent
+investigations of Calkins,[288] infusoria, weakened by degeneration, may
+become young again not only by conjugating with their kind, but by the
+addition of bouillon or extract of brain to the medium in which they
+live.
+
+Real old age is a phase of existence in which the natural forces abate
+never to be renewed. In animals, the life cycle of which is very
+definite, the signs of senile degeneration are not visible. Insects, in
+the adult condition, very often live only a short time, and die without
+displaying the slightest mark of age. In the case of lower vertebrates,
+old age is little known, and has few signs. On the other hand, mammals
+and birds display senile atrophy in a marked fashion.
+
+Some species of birds live to a great age, longevity being more common
+than among mammals. Cases in which birds such as geese, swans, ravens,
+and some birds of prey, have been known to reach the age of fifty
+years,[289] are not uncommon, whereas such an event is very rare in the
+case of a mammal. Even small birds, such as canaries, may live as long
+as twenty years. Parrots are especially long-lived birds. Cockatoos have
+been known to reach the age of eighty years and more. I myself have had
+opportunities of observing a South American parakeet (_Chrysotis
+amazonica_) which lived more than eighty-two years, longer than is usual
+even with parrakeets. Several years before it died the bird showed
+unmistakable signs of old age. It became less lively, its plumage,
+although it did not whiten, lost much of its brightness, and the joints
+of the claws showed evidence of the presence of disease. In short, the
+parrakeet was obviously worn out and debilitated.
+
+Mammals show the signs of age even more plainly than do birds. A dog
+reveals old age by its slow movements, its white hairs, and worn teeth.
+The appearance of such an animal is never agreeable, while it is often
+dirty and ill-tempered. Brehm describes the old age of a dog as follows:
+“At twelve years of age a dog has grown old, and his gait and whole
+organisation show signs of age. The coat is no longer glossy; the
+forehead and muzzle are grey, the teeth are blunted or have fallen out.
+The animal is lazy and apathetic. Many such dogs are dumb and blind.
+Dogs may live for twenty, six and twenty, or even thirty years, but such
+cases are most unusual.”
+
+As the dog is a domesticated animal, it might be argued that its old
+age, with its manifest signs of decrepitude, is the result of the
+artificial conditions of its life. To decide on this point it is
+necessary to examine an instance of old age in a wild animal. This
+presents certain difficulties since wild animals when old and feeble
+become an easy prey to carnivorous enemies. It will best serve our
+present purpose to consider such information as has been collected
+regarding the period of old age in anthropoid apes.
+
+The natives of Borneo have observed “old orangs, which have not only
+lost their teeth, but being too feeble to climb, live on the fallen
+fruits and herbs.”[290] Gorillas, according to Savage, turn grey in
+their old age, from which has arisen the erroneous view that there are
+two species of the gorilla.
+
+In their wild state, monkeys, like ourselves, are subject in their old
+age to various distressing ailments. Senile degeneration, then, which is
+universally looked upon as one of the greatest evils of life, is by no
+means restricted to the human race. Old age, as portrayed in the
+Buddhist legend, referred to in chap. vi., is perhaps somewhat
+exaggerated, but this period of life is undoubtedly characterised by
+changes of such a nature as considerably to affect the happiness of the
+old. Buddha, being a pessimist, took too dark a view of this, but let us
+hear what optimists have to say on the subject. Max Nordau, a doctor, a
+writer of books and a journalist, says: “Physically speaking, an old man
+presents an unpleasant picture of decrepitude to the casual observer.
+Morally speaking, he is a blind and pitiless egotist, having lost all
+interest in anything outside himself. Intellectually he becomes
+feeble-minded and narrow in his views, being governed by antiquated
+notions and prejudices, and incapable of grasping new ideas.”[291]
+
+It may be objected that I am here supporting my argument by quoting from
+a writer who, in his capacity of clever journalist, rather forces the
+note. Let me therefore refer to what a learned physiologist said when
+addressing a serious audience assembled for the purpose of obtaining
+truth and information from his lips. After dealing in broad outline with
+the physical degeneracy caused by old age, Longet[292] draws the
+following mental picture: “The old feel that their task in life is
+accomplished, and believe themselves to be universally grudged the space
+they occupy in the world. This renders them suspicious of all around
+them, and jealous of the young. Their craving for solitude and the
+uncertainty of their tempers are due to the same cause. All old people
+are not like this, of course. The hearts of some remain youthful and
+beat strongly within their feeble frames, but, as a general rule, they
+are morose and a nuisance to themselves and others, excepting when they
+are surrounded by their children or grandchildren, who like to listen to
+them about the past, and who make excuses for the present. Thus the
+years speed onward, every round of the clock bringing the end nearer,
+and every hour adding a new wrinkle to their faces, some fresh weakness
+and some new regret. Their bodies ... become decrepit; their backbones,
+too weak to hold them upright, curve over and bend them downwards
+towards the earth.”
+
+There can be no doubt but that the period of old age is sad, and a
+thorough knowledge of it is necessary before it can be understood.
+Disease can only be successfully dealt with when the cause of its
+presence is known, and so it is with old age.
+
+Is it possible, one might ask, at the present stage of the world’s
+knowledge, to define, with even approximate accuracy, the characteristic
+features of senile decay? The task is difficult, for although the
+subject is very important, few facts have been collected.
+
+It is common knowledge that the flesh of old animals, used as food, is
+tough. An old fowl cannot be compared with a tender and juicy chicken.
+Organs such as the liver and kidneys are much harder in the case of old
+animals. The horny flesh of old animals is often compared with
+boot-leather. Although the comparison does not pretend to be scientific,
+it is far from being incorrect. Boot-leather is made from the hides of
+animals; that is to say, of a very resistant material that is called
+“connective tissue,” and which consists of a dense mass of fibres,
+mingled with the living elements or “connective tissue” cells. This
+tissue is very durable and so is employed for boots and shoes.
+
+The infiltration of any organ with connective tissue makes it tough and
+unpalatable. This hardening is called a _sclerosis_ (of the liver,
+kidneys, &c.). In old age many organs exhibit this tendency to hardening
+or sclerotic degeneration. The fact has been known for long, but its
+significance has been perceived more recently. Demange,[293] in his
+monograph on the organic changes associated with old age, states as
+follows: “Besides atrophy and degeneration of the parenchymatous
+elements,[294] there is to be observed a profound change in the
+framework of connective tissue, which serves to support the organs. In
+some cases the skeletal framework of an organ becomes more conspicuous,
+simply on account of the degeneration of the cells; this is the
+condition usually present in the liver of aged persons. More often,
+however, the connective tissue receives some kind of stimulation, which,
+although it does not amount to inflammation, brings about an active
+growth and resulting sclerosis. According to the particular case, the
+hardening occurs in the form of isolated patches or strands, or affects
+the whole periphery or even the depths of the organ, and smothers the
+higher elements in its meshes, so producing a further degeneration. The
+cellular elements disappear gradually, connective tissue taking their
+place, and the change may be so profound, that as in the case of the
+prostate gland, the altered organ may actually transcend the normal
+size, partial or general atrophy, however, being more often the result.”
+
+Sclerosis in old people sometimes takes the form of a hardening of the
+liver (cirrhosis of the liver) or of the kidneys (renal cirrhosis), but
+it is the arteries which are most commonly affected by it, producing a
+symptom of degeneration which is called arterial sclerosis.
+
+Cazalis long ago originated the oft-repeated aphorism: “A man is as old
+as his arteries,” these vessels, by means of which the blood is
+distributed throughout the whole system, being of immense importance in
+the economy of the organism. When the connective tissue is so freely
+developed as to cause a hardening of the arteries, these are hampered in
+the exercise of their function and become very brittle. According to
+Demange, all the special modifications undergone by the body during the
+period of old age may be attributed to this atrophy of the arteries, but
+this theory is proved to be an exaggeration by the fact that post
+mortems on the aged frequently reveal the presence of little or no
+arterial sclerosis.
+
+It might fairly be supposed that the hardening seen in many organs of
+the body during the period of old age is universal, and lends greater
+strength to the frame. The bones, which are separated from one another
+in youth, become welded together in old age owing to the calcareous
+deposits in the joints, and the ossification of the joints between the
+vertebra frequently causes the backbone to assume the appearance of a
+continuous bone, the greater part of the cartilage having become
+ossified. In spite of this, and as though for the purpose of proving how
+physically full of contradictions is the period of old age, the human
+frame actually becomes lighter and the quantity of component mineral
+substances becomes less. This brings about a liability to fracture of
+the bones in old people. The fracture of the neck of the femur is a
+constant cause of death in the aged, as occurred for instance in the
+case of Virchow, one of the most distinguished medical scientists of the
+nineteenth century.
+
+Is science, it may be asked, in a position to state precisely what are
+the principal modifications which occur in the tissues of old people? At
+the International Congress of Medicine held at Berlin in 1890, a
+well-known German anatomist, Merkel,[295] attempted to reply to this
+question. Speaking of the tissues of old people, he tried to show that
+certain of these, such as the skin and the mucous membrane (the
+epithelial tissues), preserve their youthful characters to the end,
+whereas others, such as the connective tissues, display profound
+changes. This essay was the first attempt to form a picture of the
+details of senile degeneration, but it did not reach any simple, general
+conclusion.
+
+Later on, I myself[296] tried to complete the work, and for the purpose
+made use of the published results of all the investigators who had
+studied senile degeneration. I gave a summary of my conclusions in the
+following words: “In senile atrophy the same condition is always
+present: _the atrophy of the higher and specific cells of a tissue and
+their replacement by hypertrophied connective tissue_.” In the brain,
+the nerve cells disappear; that is to say, the cells which subserve the
+higher functions such as intellectuality, sensation, control of
+movement, and these are replaced by elements of a lower kind, in
+especial by neuroglœa, a kind of connective tissue of the brain. In the
+liver, the hepatic cells, of great importance to the nutrition of the
+organism, yield to connective tissue. In the kidneys, that tissue
+invades and blocks the tubes by which the necessary process of
+eliminating soluble waste matter is accomplished. In the ovaries, the
+ova, the specific elements which serve to propagate the race, are
+similarly eliminated and replaced by granular cells, a variety of
+connective tissue. In other words, a conflict takes place in old age
+between the higher elements and the simpler or primitive elements of the
+organism, and the conflict ends in the victory of the latter. This
+victory is signalised by a weakening of the intellect, by digestive
+troubles, and by lack of sufficient oxygen in the blood. The word
+conflict is not used metaphorically in this case. It is a veritable
+battle that rages in the innermost recesses of our beings. Distributed
+throughout every part of our bodies are certain cells which fulfil
+special functions of their own. They are capable of independent
+movement, and also of devouring all sorts of solid matter, a capacity
+which has gained them their name of phagocytes or voracious cells. The
+function these phagocytes fulfil is a very important one, for it is they
+that congregate in vast numbers around microbes or other harmful
+intruders, in order to devour them. Effusions of blood and other
+elements, on penetrating to parts of the body where their presence is
+disadvantageous, are absorbed by these phagocytes. In cases of apoplexy,
+where blood is shed into a part of the brain, setting up paralysis, the
+phagocytes cluster round the clot and devour the blood corpuscles it has
+encased. This absorption is a lengthy process, but by degrees, as the
+pressure of the effusion of blood is removed from the brain, and
+paralysis disappears, the health of the organism may become completely
+restored, recovery in such a case being due to the work of the
+phagocytes. After childbirth, when the uterus presents the appearance of
+a great open wound clotted with blood, it is again the phagocytes that
+clean it and re-establish the normal condition. It is plain, therefore,
+that the part played by these cells is beneficent.
+
+The phagocytes may be divided into small active phagocytes, generally
+known as the microphags, and larger phagocytes called macrophags, which
+are sometimes active and sometimes still. The former, which are produced
+in the marrow of the bones, circulate freely in the blood, and occur as
+some of the white blood corpuscles, or leucocytes. They are
+distinguishable by their oval shape which facilitates their easy passage
+through the smaller blood-vessels, and allows of their accumulating in
+great numbers in the exudations that form around microbes. These
+exudations may be formed extremely rapidly, and so may arrest infection
+in the case of many diseases.
+
+The absorption of extravasations of blood and the healing of wounds are
+the work of the macrophags. In a general way, the microphags may be said
+to rid us of microbes, and the macrophags to heal mechanical injuries,
+such as hæmorrhages, wounds, and so forth. Macrophags possess a single
+unlobulated nucleus, and occur as white corpuscles in the blood, lymph,
+and exudations, or as the fixed cells in connective tissues, the spleen,
+and the lymphatic glands, &c.
+

+
+[Illustration:

+  FIG. 15. Cell from the brain of a woman 100 years old being devoured

+]
+
+The phagocytes are endowed with a sensitiveness of their own, and by
+means of a sense of smell or taste are able to recognise the nature of
+their surroundings. According to the impression made upon this sense,
+they approach the object which arouses it, exhibit indifference to it,
+or withdraw from its vicinity. When, however, an infectious microbe
+finds its way into the body, the microphags are attracted by its
+excretions and swarm into the exudations surrounding it. The macrophags
+play a very important part in bringing about senile decay. The atrophy
+of the kidneys in old persons is attributable to their agency (Fig. 14).
+They accumulate in large quantities in these organs, clustering round
+about the renal tubes which they ultimately cause to disappear. Having
+appropriated the place of the renal tubes, the macrophags proceed to
+form connective tissue, which thus takes the place of the normal renal
+tissue. A similar process occurs in the other organs that degenerate in
+old age. In the brains of old persons and animals, for instance, it is
+known that a number of nervous cells are surrounded and devoured by
+macrophags (Fig. 15). Judging from the investigations mentioned above, I
+think I am justified in asserting that senile decay is mainly due to the
+destruction of the higher elements of the organism by macrophags. This
+conclusion has been confirmed by means of direct observation, which was
+the more necessary as it is contrary to the opinions of some biologists.
+Marinesco,[297] an authority upon everything connected with the nervous
+system, has disputed my theory, asserting that the destruction of the
+specific elements in the nervous centres of old persons is not brought
+about through the agency of macrophags. In support of his theory, M.
+Marinesco was good enough to send me a series of preparations from the
+spinal marrow of persons of very advanced years from which evidence of
+destruction by means of phagocytes or phagocytosis, was completely
+absent. I freely admit the absence of phagocytosis in M. Marinesco’s
+preparations, but these were derived from the cells of spinal marrow,
+which is much less subject to the ravages of senile decay than is the
+brain. Even in the lower portions of the encephalon, senility and its
+parallel, phagocytosis, are uncommon, whereas in the brains of old
+persons, which are more generally affected by senile decay, the higher
+elements are clearly shown to undergo destruction by macrophags (Fig.
+15). The same phenomenon may be observed in the case of parrots and dogs
+of advanced age, and in other animals.
+
+So universal a symptom of old age is the invasion of the tissues by
+macrophags, that it must be regarded as of immense importance. In order,
+however, to determine more precisely the nature of the function
+fulfilled by these phagocytes, it was necessary to select a specially
+favourable subject of investigation. My choice fell upon an examination
+into the causes of the hair turning white,[298] that being as a rule the
+first visible sign of approaching old age.
+
+Hair, before it has lost its colour, is full of pigment scattered
+throughout the two layers of which each hair is composed. At a given
+moment, the cells of the central cylinder of a hair become active, and
+proceed to devour all the pigment within their reach. Once they are
+filled with coloured particles, these cells, which are a variety of
+macrophag (generally called pigmentophags or more properly speaking
+chromophags), become migratory, and, quitting the hair, either find
+their way under the skin or leave the body (Fig. 16). The
+colouring-matter of the hair is removed in this way by chromophags,
+leaving the hair colourless.
+
+The process by which hair becomes white is of importance, because it
+shows that the activity of macrophags is a dominant factor in bringing
+about senile decay. The brittleness of old people’s bones is probably
+due to a similar cause, _i.e._, to the absorption and destruction of the
+framework brought about by macrophags invading the layers of bone. There
+is still much that remains unknown in this subject, which is well worthy
+of special research.
+

+  FIG. 16. Hair about to become grey. Chromophags transporting the
+    pigment granules.
+]
+
+The activity acquired by macrophags during old age is closely connected
+with the phenomena that are characteristic of certain chronic
+complaints. Sclerosis in old persons belongs to the same category as
+organic sclerosis, which may be set up by various morbid influences. The
+analogy between senile decay of the kidneys and chronic nephritis,
+commonly called interstitial nephritis, is incontestable. The
+destruction of nervous cells through the agency of macrophags, which we
+have already mentioned as occurring in old age, is equally a symptom of
+several diseases of the nervous centres, such as general paralysis of
+the insane. Arterial sclerosis in old persons is actually an
+inflammatory disease, similar to the inflammation of the arteries set up
+by other maladies.
+
+The similarity between senility and disease has long been recognised,
+and partly accounts for the repugnance we all experience at the approach
+of old age. In childhood and early youth people regard themselves as
+older than they really are, and long to be “grown-up,” but having once
+arrived at man’s estate, they do not wish to grow old. An instinctive
+feeling tells us that there is something abnormal in old age. It cannot
+be regarded as a part of healthy physiological function. No doubt,
+because old age is the inevitable lot of mankind, it may be termed
+normal, in the same fashion as we call the pains of childbirth normal,
+since few women escape them. In both cases, however, we have to deal
+with pathological rather than physiological conditions. Just as every
+effort is made to relieve the sufferings of a woman in labour, so it is
+natural to try to suppress the evils accompanying old age, but whereas
+in childbirth an anæsthetic affords relief, old age is a chronic malady,
+a remedy for which is much harder to find. We have seen that in old age
+a struggle takes place between the higher elements and the phagocytes,
+the end being usually a weakening in vitality of the former, while the
+activity of the latter is enormously increased. It would appear, arguing
+from this, that one means of fighting against old age, pathologically
+speaking, would be to strengthen the higher elements of the organism,
+and to weaken the aggressive capacities of the phagocytes. Let me at
+once warn the reader that this is not presented as a definite, but as a
+possible solution of the problem, and is offered for consideration like
+many other hypotheses on scientific questions. The properties of
+cellular elements are easily changed when subjected to various
+influences, and it is therefore not irrational to seek some means of
+strengthening the blood corpuscles, nerve cells, liver cells, muscular
+fibres of the heart, and so forth. The task has become easier since the
+discovery of serums that have specific actions on the tissues.
+
+In the third chapter I stated that serums were known which give
+precipitates only with the blood of man and of his near relatives the
+anthropoid apes. Serum of this kind has a definite specific action.
+Serums may be prepared that dissolve only the red corpuscles of
+particular species of animals, and that are without action on the other
+organic elements. It has been found possible, even, to prepare a serum
+that arrests instantaneously the movements of human spermatozoa, and
+that is neutral to the similar cells of other animals.
+
+These serums are all prepared in the same way. The cellular elements in
+question, spermatozoa or red corpuscles, cells of the liver or of the
+kidney, taken from one animal, are injected into an animal of another
+species. After several injections have been made, the serum of the
+animal operated on becomes active with respect to the cells introduced
+into its body. These serums were discovered by J. Bordet of the Pasteur
+Institute, but the results have been confirmed by investigators in other
+countries. The serums are specifically _cytotoxic_, that is to say, they
+poison particular kinds of cells.
+
+Now it has been shown that such serums, employed in small doses, do not
+kill or dissolve the specific tissue elements, but actually strengthen
+them.[299] Here the case is analogous with the action of poisons, such
+as digitalis, which kill in strong doses, but which in weak doses
+improve or strengthen the action of certain tissues. In accordance with
+this indication, experiment has shown that small doses of a serum which
+is capable of dissolving the red corpuscles of human blood, actually
+increase the number of those in the body of a patient treated by
+injections. In the same way, in the case of a serum large doses of which
+destroy the red corpuscles of a rabbit, small doses increase the number
+of these elements in the blood.
+
+Here there seems to be a rational method by which we may strive to
+strengthen the higher elements of the human body, and so prevent them
+from growing old. The task, at first sight indeed, seems an easy one,
+only necessitating the injection of a horse (or other animal) with
+finely minced atoms of human organs, such as brain, heart, liver,
+kidney, &c., when serums could be drawn off in the course of a few
+weeks, capable of acting upon those organs. In reality the process would
+be a very difficult one to carry out, as human organs are rarely
+obtainable in a condition suitable for injecting into animals. Post
+mortems can only be legally made twenty-four hours after death, and
+there are many other obstacles in the way of removing organs from dead
+bodies. Even if all these difficulties were overcome, another difficulty
+that would present itself would be the experimenting with various doses
+of cytotoxic serums of various strength. It is not therefore to be
+wondered at that the attempt to reinforce the higher elements of the
+human organism will require much time. If it be necessary to strengthen
+the higher elements (nervous, hepatic, renal, and cardiac cells), it is
+plain that they undergo a progressively weakening process. It would be
+of the highest importance to ascertain the cause of this, for the
+knowledge would be a guide to future action.
+
+The similarity between senile decay and the diseases entailing atrophy
+in the more important human organs suggests a similitude in cause.
+Scleroses of the brain, kidneys, and liver frequently originate in
+intoxication by poisons such as alcohol, lead, mercury, and so forth, or
+the disease may be induced by some virus, the virus of syphilis being a
+common cause.
+
+The immense importance of venereal disease as a malevolent factor in the
+phenomena of old age, is especially manifested in arterial sclerosis.
+According to the careful investigations of a Swedish doctor,
+Edgren,[300] published in his “Monograph on Arterial Sclerosis,” one
+case in every five of this disease is caused by syphilis, and he shows
+that chronic alcoholism is an even more frequent cause (25 per cent.).
+These two factors when united are responsible for nearly half (45 per
+cent.) the cases of arterial sclerosis that occur. Syphilitic virus and
+alcohol act as poisons which bring about first degeneration and
+brittleness of the arterial walls, and eventually a weakening of the
+higher elements of the organism. The phagocytes, being cells of an
+inferior order, are less sensitive to these poisons, which accounts for
+their victory over the poisoned elements.
+
+Rheumatism, gout, and infectious diseases only play a secondary part in
+setting up arterial sclerosis. Edgren asserts, as the result of very
+careful calculation, that in nearly every fifth case he found it was
+impossible to account for the origin of arterial sclerosis. In the
+majority of cases the sufferers were elderly persons who, according to
+Edgren, “were afflicted with physiological sclerosis.”[301]
+
+I take it that this sclerosis of unknown origin was by no means
+physiological but was pathological like that set up by syphilis or
+alcoholism. The question then arises whence comes the poison in such
+cases? In syphilis there is a virus of a definite nature to deal with,
+which causes infection or poisoning, and brings about arterial
+sclerosis, general paralysis, and other serious ailments. Alcoholism is
+a poison arising from fermentation, excited by microscopical fungi
+related to true microbes. Instances of arterial sclerosis which are due
+neither to syphilis nor to alcohol poisoning nor to any other known
+cause, can only be accounted for as probably arising from poisoning set
+up by the mass of microbes congregated in the human intestines. Among
+these microbes there may be some that are harmless, and possibly even
+beneficial, but there are undoubtedly a great number the presence of
+which is extremely prejudicial to health and life. It is impossible to
+enter into the details of such an important question, and a brief
+mention must suffice.
+
+The human intestine contains an enormous quantity of bacteria, which,
+according to the recent investigations of Strassburger,[302] increase at
+the rate of 128,000,000,000,000 each day. These microbes, of which there
+are few in the digestive portion of the alimentary canal, are very
+numerous in the large intestines, _i.e._, in the lower part containing
+the waste material. The remains of undigested foods and the mucous
+secretions form a medium very favourable to the growth of microbes. This
+bacterial flora constitutes a third part of the human excreta. It is
+very varied, and contains an immense number of different species, among
+which are bacilli, cocci, and many kinds of other bacteria, about which
+little is known. The distribution of this bacterial flora shows that it
+contributes nothing to the well-being of man, being scanty in the
+digestive portions of the body, and abundant in other parts of the gut.
+This fact alone suffices to refute the theory of those who attribute
+great functional importance to the intestinal flora. This theory
+originated principally from the fact that certain animals perish when
+brought up under special conditions protecting them from the presence of
+microbes. Schottelius[303] was the first to try the experiment of
+rearing chickens in a cage specially constructed for this purpose. The
+chickens hatched out, and lived for a few weeks: then, there being no
+microbes within them and only sterilised food being given, instead of
+increasing in weight, they became thin and showed signs of starvation.
+Schottelius supplied them with food from which bacteria were no longer
+excluded, upon which the chickens rallied, and soon became completely
+restored to health. Madame Metchnikoff[304] tried a similar experiment
+with tadpoles, which, when kept in vessels and fed upon bread containing
+the usual microbes, developed normally, but which, when reared under
+conditions entirely free from the presence of microbes, lived on for
+some months, but in a degenerate condition, their development being
+arrested.
+
+On the other hand, Nuttall and Thierfelder[305] succeeded in keeping
+alive for several days new-born guinea-pigs, the alimentary canals of
+which were free from microbes, and which were fed only on absolutely
+sterilised milk and vegetable matter. Notwithstanding this complete
+absence of microbes the guinea-pigs developed well.
+
+As the two sets of experiments were conducted under conditions arranged
+so carefully that the chance of error was excluded, it is important to
+try to reconcile the apparently contradictory results. There is one
+point common to these three experiments, _i.e._, that they were all
+executed upon newly born creatures. Now it is well known that at birth
+the digestive juices are often very imperfectly secreted. In the case of
+the guinea-pigs, these juices sufficed in quantity for the digestion of
+the diet provided, whereas in the cases of the chickens and the
+tadpoles, the digestive juices were incapable of fulfilling their
+function satisfactorily, and the introduction of microbes endowed with
+considerable digestive capacity into the intestines compensated for the
+functional inefficiency of the gastric juices. In addition to the
+guinea-pigs experimented upon by Nuttall and Thierfelder, there may be
+mentioned a whole series of lower creatures such as the larvæ of mites
+and other insects which are able to digest such indigestible material as
+wax and wool in spite of the total absence of microbes within their
+intestinal tubes. These experiments are corroborated by the established
+physiological fact that the gastric and pancreatic juices of mammals
+easily digest the most varied kinds of foods, even if treated so
+antiseptically as to ensure the total exclusion of microbes from the
+intestines.
+
+I need not go further into this subject as the facts which I have cited
+suffice for my present purpose. The complete atrophy of the large
+intestines in the case of the woman referred to in chap. iv. proves not
+only that this portion of the alimentary canal is not indispensable to
+healthy life, but that life may be maintained in the absence of the
+flora of the large intestines. And this really is the centre of the
+problem. The useless bacterial flora may give rise to serious or fatal
+maladies. Wounds of the abdomen are really serious only when they
+penetrate the large intestines and so allow the entrance of bacteria
+from that region to the peritoneal cavity. In such an event, the
+microbes rapidly multiply in the organism and produce a grave and
+frequently mortal illness. So long as the microbes remain within the
+intestines very few of them get into the circulation, and with these few
+the organism is able to cope. While most of the microbes are confined
+within the walls of the alimentary canal, the soluble excretions
+produced by them pass through into the lymph and blood. Quite a number
+of different facts establish this. Thus, for instance, it has been known
+for long that the urine of human beings and of animals contains a series
+of substances such as derivatives of phenol, indol, creosol, skatol, and
+so forth. In certain diseases the amount of these substances greatly
+increases. The stagnation of the contents of the intestines increases
+the amount of phenol and indol. Such facts and many others make it
+probable that these substances are the products of the bacterial flora
+of the intestines. They are absorbed by the intestinal wall, pass into
+the general circulation, and may give rise to various symptoms of a more
+or less serious nature.
+
+Baumann, who has done much work on the subject, has brought together a
+series of arguments supporting the bacterial origin of the presence in
+the urine of the substances in question. Ewald, working from another
+point of view has obtained strong confirmation of Baumann’s suggestions.
+He had the opportunity of making observations on a female patient, in
+whom, on account of a strangulated hernia, an intestinal fistula was
+established. Throughout the time during which the large intestines were
+inactive, the urine contained neither phenol nor indol. But as soon as
+the fistula was closed and communication with the large intestine had
+been re-established, phenol and indol reappeared in the excreta. Ewald
+formed the opinion, therefore, that these substances were products of
+the large intestine.
+
+I need not weary the reader with more of the facts serving to show that
+the bacterial flora of the large intestines is the source of many
+poisons harmful to the body. It is among such substances that we must
+look for the slow poisons which, in the absence of syphilis or
+alcoholism, produce the arterial sclerosis of old age.
+
+In the fourth chapter I gave reasons to support my view that the large
+intestine in mammals had been developed because, by storing the products
+of digestion, it allowed them to run long distances without stopping,
+and so was an advantage in the struggle for existence. Moreover, the
+microbes which abound in the contents of the gut make it possible to use
+certain substances such as cellulose, that are difficult to digest. But
+these two advantages do not count in the case of the human race. Man
+does not secure his prey or escape from his enemies by the rapidity of
+his locomotion. The great development of his intellectual powers has
+given him advantages of another kind. Moreover, by the use of cooking
+and the cultivation of plants of high nutritive value, he is able to
+dispense with the digestion of cellulose.
+
+There is another side to the picture. Ignorant of death and of old age,
+mammals have acquired the advantages of a large intestine at the expense
+of longevity. I have already stated that birds live longer than mammals.
+Birds are practically devoid of a large intestine, and maintain a
+bacterial flora very much poorer than that found in mammals. There is
+one exception to this rule, an exception of great importance. Ostriches
+and their allies, the largest known birds, are characterised by absence
+of the power of flight and by rapidity of terrestrial locomotion by
+which they escape their enemies. These are the only birds in which the
+large intestine is well-developed. The duration of life is much less in
+their case than in that of smaller birds, such as parrots, ravens, and
+swans. According to M. Rivière, who has been engaged in ostrich farming
+in Algeria, these large birds do not live more than thirty-five years.
+The mode of life, and the shorter duration of life, the huge development
+of the large intestines and the rich bacterial flora found therein make
+the ostriches much more like mammals than birds.
+
+It is to be noticed that many birds in which the duration of life is
+long do not possess a cæcum, the portion of the alimentary canal that
+contains most bacteria. Examination of the intestinal contents of
+parrots shows that there exist in these birds very few microbes. A
+comparative study shows plainly that the existence of an abundant
+intestinal flora, useless for digestion, helps to shorten life by
+producing bacterial poisons which weaken the higher elements and
+strengthen the phagocytes.
+
+The human race has inherited from its ancestors an enormous large
+intestine and conditions favourable to the life of bacteria. It has to
+endure the disadvantages of this heritage. On the other hand, the brain
+of man is very highly developed, and with the increase of intellectual
+power has come a consciousness of old age and death. Our strong will to
+live is opposed to the infirmities of age and the shortness of life.
+Here lies the greatest disharmony of the constitution of man.
+
+If we desired to make the phenomena of old age physiological rather than
+pathological, it would be necessary to reduce the evils arising from the
+presence of a large intestine. It is impossible, I may at once say, to
+wait for the operation of forces independent of the human will and that
+might lead to the suppression of an organ which has become useless. Man,
+guided by exact science, must strive to accelerate or anticipate such a
+result. In spite of the progress of surgery, I do not expect to find in
+our time that the large intestine will be removed by operation. Perhaps
+in the distant future such a proceeding will become normal. For the
+present it is more reasonable to attack the harmful microbes of the
+large intestine. In the varied flora of that region there exist microbes
+termed anærobic, because they are able to live in the absence of free
+oxygen, obtaining what they require by the decomposition of organic
+matter. Such decomposition is attended by fermentations and
+putrefactions, and the production of poisons, such as the alkaloids
+(ptomaines), fatty acids, and even true toxins.
+
+In the human intestines under normal conditions, putrefaction occurs
+only very slightly, or does not occur at all. But in intestinal diseases
+of children and of adults, the microbes of putrefaction multiply
+abundantly and produce copious secretions which inflame the intestinal
+walls. To avoid these diseases of putrefaction in the case of infants,
+it has been suggested to use as food only sterilised milk or other foods
+quite free from microbes. This regimen has proved extremely successful.
+
+In the investigation of the factors that hinder putrefaction, it has
+been noticed that milk putrefies with considerable difficulty, whereas
+meat, preserved under the same conditions, decomposes very readily.
+Investigators have attributed the stability of milk to the presence of
+casein or of milk-sugar. However, investigations recently made by
+Bienstock[306] and confirmed by Tissier and Martel[307] have proved
+the existence of certain microbes that hinder the putrefaction of milk.
+These are in particular the microbes that sour milk, _i.e._, cause the
+formation of lactic acid, and which are antagonistic to the microbes of
+putrefaction. The latter multiply only in an alkaline medium. The lactic
+acid microbes produce large quantities of acid and so hinder the
+multiplication of the organisms of putrefaction. Putrefaction takes
+place rapidly, in spite of the presence of the lactic acid microbes, if
+there be added soda to macerations of meat or milk. Such facts explain
+how it is that lactic acid frequently stops some cases of diarrhœa, and
+why treatment with lactic acid is so useful in maladies associated with
+putrefaction of the intestinal contents. It makes intelligible,
+moreover, the medicinal value of fermented milk.
+
+Rovighi,[308] an Italian physician, drank daily a litre and a half of
+kephir, a preparation made by subjecting milk to lactic acid and
+alcoholic fermentations. He found that in a few days the products of
+intestinal putrefaction in his urine either disappeared or were greatly
+reduced.
+
+It is plain, then, that the slow intoxications that weaken the
+resistance of the higher elements of the body and that strengthen the
+phagocytes may be arrested by the use of kephir, or still better of
+soured milk. The latter differs from kephir in that it contains no
+alcohol, and alcohol in course of time diminishes the vitality of some
+important cells in the body. The presence of a number of the lactic acid
+bacteria is inimical to the growth of the bacteria of putrefaction, and
+so is of great service to the organism.
+
+But it is not enough merely to introduce useful microbes into the body.
+We must also prevent the entrance of “wild” microbes, many of which are
+harmful. Soil, especially when it has been manured, contains large
+numbers of microbes, some of which are harmful. Bienstock found that the
+soil of the strawberry-beds in his garden contained the bacilli of
+tetanus. For three weeks he swallowed some of this soil, but found that
+the bacteria were destroyed in his intestines, which he attributed to
+the action of the normal bacterial inhabitants of the alimentary canal.
+It is probable that if this arresting action were weakened the body
+would be infected by tetanus from spores of the tetanus microbe
+swallowed with earth or strawberries or green vegetables. Moreover,
+besides the organisms of tetanus, there are many other dangerous
+anærobic bacteria in manured garden soil.
+
+Obviously we should eat no raw food, but confine our diet rigidly to
+food that has been thoroughly cooked or sterilised. The exclusion of
+“wild” microbes and the introduction of beneficial microbes, such as
+those of lactic acid fermentation, must be of great service to health. I
+know of individuals who have derived great benefit from such a regimen.
+
+Science, even in its present imperfect condition, has many weapons by
+which to prevent or at least diminish the slow and chronic poisoning of
+the organism that leads eventually to the degeneration of the higher
+elements. When these elements are being destroyed by syphilis or
+alcoholism the struggle must be directed against these evils. It is long
+since we have known how to do this; that success has not been greater is
+due to the carelessness of the people who are concerned.
+
+To strengthen the resistance of the higher elements and to transform the
+“wild” population of the intestine into a cultured population, these are
+the means by which the pathological symptoms may be removed from old
+age, and by which, in all probability, the duration of the life of man
+may be considerably increased.
+
+If it be found impossible to eliminate all the harmful microbes from the
+flora of the intestines, those that are refractory may be rendered
+harmless by appropriate serums. We know already a serum that is specific
+against the microbe of botulism, an organism capable of exciting serious
+disturbance if it gain entrance to the alimentary canal.
+
+Our inmost convictions assure us that life is too short, and since the
+remotest ages attempts have been made to prolong it. I need hardly
+mention the quest of the Middle Ages for an elixir of life, but many
+thoughtful men have occupied themselves with the problem.
+
+Descartes, who was deeply interested in the subject, believed himself to
+have found a mode of lengthening human life. Bacon published a tract on
+life and death, and in it gave advice as to how old age might be
+reached; blood-letting and the use of saltpetre were parts of his
+specific.
+
+One of the oldest methods in the world consisted in bringing old men in
+contact with the bodies of young girls. David, King of Israel, employed
+this method, which at a much later period came into fashion.
+
+Eighteenth-century quacks proclaimed a number of specifics, among which
+was the “holy water” of Saint Germain, an infusion of senna, merely
+purgative in its effects. It is certain that some of the medicines used
+for the purpose, by emptying the large intestine, decreased the
+bacterial flora, and so checked the formation of the poisons that are
+harmful to the higher elements.
+
+Hufeland,[309] a well-known German professor, published towards the end
+of the eighteenth century, a work called “La Macrobiotique”; or, “the
+Art of Prolonging Human Life.” This treatise had a great vogue in its
+day, and contained many interesting and just observations. Besides
+advocating cleanliness and moderation, Hufeland advised that “we should
+use vegetable rather than animal food, as animal food was more liable to
+putrefaction, whilst vegetable substances contained an acid principle
+that retarded our mortal enemy, putrefaction.”[310] Here the physician
+of a day long past anticipated one of the discoveries of modern science.
+
+In our time scientific men have not ceased to concern themselves with
+the prolongation of human life. Professor Pflüger, of Bonn, one of the
+most distinguished of living physiologists, has published an essay[311]
+in which he gave the results of his inquiries into this subject. He
+first stated that investigations into the habits of those who had
+attained a great age did not give information sufficiently exact.
+Pflüger laid stress on the means of avoiding infectious maladies, and
+summed up as follows: “Finally, I can do no better than to associate
+myself with the advice given in all the treatises on the prolonging of
+life: avoid the things that are harmful and be moderate in all things.”
+
+A year later, a well-known German physician, Dr. Ebstein[312] published
+a very careful treatise on the same subject. He had been struck by the
+fact that among those who have reached a great age, there have been
+several who had led an exuberant life, full of excesses, notably in the
+consumption of alcohol. None the less, Ebstein advised either a complete
+avoidance of alcoholic liquor, or at the most an extreme temperance in
+the use of it. He prescribed in addition the simplification of the
+conduct of life and the avoiding of anything that is unwholesome.
+
+Study of such works, which are written in a scientific spirit, convinces
+me that a science of the prolongation of life could be built up. An
+exact investigation of the phenomena of old age would contribute to this
+object. At any rate, we cannot set aside as chimerical plans to make old
+age a natural process, and one easy to bear. I believe, moreover, that
+attempts to prolong life deserve to be encouraged, the more so as
+instances of longevity are already numerous.
+
+Quite a number of cases of centenarians who have preserved intellect and
+vigour until death have been recorded. It is unnecessary to relate the
+histories of these persons, of whom some attained such ages as 120, 140,
+and even 185 years (Saint Mungo of Glasgow). My friend, Professor Ray
+Lankester,[313] thinks that such unusually old persons are monstrosities
+comparable with those who have attained a gigantic stature. But
+centenarians are more numerous than giants, and while the latter exhibit
+marked signs of pathological weakness the former surprise us by their
+health and vigour.
+
+The longevity of the Israelites recorded in the Old Testament is well
+known. No doubt there is much exaggeration in these naïve records. Was
+it an error of exaggeration to impute an age of 969 years to Methusaleh,
+or of 595 to Noah, or were these ages reckoned on a different basis?
+Henseler[314] suggested that in these cases each season was counted as a
+year, so that the age of Methusaleh was really only 242 years, a length
+of life not so vastly greater than ages recorded in modern times.
+
+There is evidence to show that in somewhat later Biblical times ages
+were reckoned in our years. Thus in the Book of Numbers (i. 3, 20, 22)
+reference is made to those “From twenty years old and upward, all that
+are able to go forth to war in Israel.” The limit of age given shows
+clearly that the years counted were our years. This interpretation is
+supported by many other passages in the Pentateuch, notably where annual
+harvest feasts are spoken of. We may therefore accept as probable the
+assignment of such ages as 100 or 120 years to several Biblical
+personages, such as Aaron, Moses, and Joshua. And the words put in the
+mouth of Jahveh may be accepted as important evidence: “And the Lord
+said, My spirit shall not always strive with man, for that he also is
+flesh: yet his days shall be an hundred and twenty years.”[315]
+
+The longevity of that remote period must have surpassed the age of the
+present time. From the circumstance that the greatest number of deaths
+occurs at the age of seventy years, Ebstein[316] has inferred that
+seventy years is the normal duration of life. Although there is no doubt
+but that the duration of human life has become longer in the nineteenth
+century, we must believe that it was still longer in Biblical times, a
+fact that is not particularly surprising.
+
+I have called attention to the important influence of syphilis in
+inducing premature and pathological old age, as that disease is a chief
+cause of arterial sclerosis and degeneration of the higher elements of
+the body. Syphilis has an influence still more serious because its
+effects are inherited. Now although the Bible refers to diseases of the
+genital organs and lays stress on circumcision, there is no direct
+evidence in it as to the existence of syphilis. Ebstein, in a treatise
+on the medicine of the Bible,[317] is confident that there is no
+reference to syphilis in that Book. Moreover, in the ancient world
+generally, syphilis was either unknown or existed only in an attenuated
+form. Haeser,[318] the author of the best modern treatise on the history
+of medicine, thinks that if syphilis did exist in the ancient world, it
+occurred in a localised form and did not become a general disease of the
+system as is the case among the moderns.
+
+Humanity would make a great stride towards longevity could it put an end
+to syphilis, which is the cause of one fifth of the cases of arterial
+sclerosis. The suppression of alcoholism, the second great factor in the
+production of senile degeneration of the arteries, will produce a still
+more marked extension of the term of life. Scientific study of old age
+and of the means of modifying its pathological character will make life
+longer and happier. Although modern knowledge is still imperfect, there
+is no reason to be pessimistic on the subject of old age.

+                               CHAPTER XI
+             INTRODUCTION TO THE SCIENTIFIC STUDY OF DEATH
+
+
+  Theory of the immortality of lower organisms—Immortality of the sexual
+  cells in higher organisms—Immortality of the cellular soul—Occurrence
+  of natural death in the case of certain animals—Natural death in the
+  Ephemeridæ—Loss of the instinct of preservation in adult
+  ephemerids—Instinct of life in the aged—Instinct of natural death in
+  man—Death of old men in Biblical times—Changes in the instincts of man
+  and lower animals
+
+
+From what I have said in the last chapter, it is plain that, perhaps
+before very long, it will be possible to modify old age. Instead of
+retaining its existing melancholy and repulsive character, it may become
+a healthy and endurable process; it may also be that the duration of
+life will be prolonged. However, it may be asked, what shall we gain by
+attaining the age of 100 or 120 years instead of 70 or 80, if there
+still remain for us the appalling fate of the inevitable annihilation of
+death. Marcus Aurelius said that he who makes a long journey and he who
+makes it short, alike meet death at the end; and that once they are
+over, three years or a century are much alike. Such assertions, however,
+do not take into account the difference in the values we set on a thing
+at different ages. A man of the age of twenty-five years and one fifty
+years old reason differently, and are affected differently by the same
+surroundings. The outlook on life changes in the same individual as he
+gets on in years. Young people judge of their impressions by comparison
+with their ideals, and as the latter are very high, they are
+dissatisfied with things as they really are. They are exacting, and
+discontented with what they can get out of the real world; grown up
+people and those of advanced years are more easily satisfied because
+they have a clearer knowledge of the true value of things. As I have
+already had occasion to point out in a previous chapter, the young are
+more inclined to pessimism than the old. We see, then, that appreciation
+of life changes with age. It is the same with regard to death. It has
+often been said that life is only a preparation for death. Cicero said,
+“From our youth upwards we must accustom ourselves to face our last
+moments without fear. If not, there is an end to peace, since it is
+quite certain that we must die.” Philosophy has been called the art of
+preparing for death.
+
+Before considering in what direction science may direct our steps
+towards solving the problem of death, which in the words of St. Paul is
+the “last enemy to be destroyed,” let us see how much is known about it.
+
+We are so accustomed to look upon death as something natural and
+inevitable, that it has long since come to be regarded as inherent in
+organisms. However, when biologists investigated the matter more
+carefully, they failed to discover any proof of the accepted doctrine.
+Observation of members of the lowest grade of animal life, such as
+infusorians and other protozoa, has shown that these reproduce by simple
+division, and in a very short time multiply to an astonishing extent.
+Generation succeeds generation, with the utmost rapidity and without the
+intervention of death; no single corpse appears in the swarming masses
+of animalculæ. From such facts, which are extremely easy to confirm,
+several biologists, and in specially Bütschli and Weismann,[319] have
+deduced an immortality of the unicellular organisms. When an infusorian
+has divided, each daughter organism rapidly completes itself and sets
+about again dividing in the fashion of its parent. The process may be
+more complicated, as in the cases where a single organism breaks up into
+several portions each of which contains an essential part of the parent
+organism. Many unicellular organisms reproduce in such a fashion, and as
+each animal divides simultaneously into a number of individuals of the
+new generation, the individuality is destroyed. It is possible to admit
+with Götte[320] that such a process is natural death, although there is
+no actual destruction and no corpse.
+
+In any event it cannot be disputed that lower organisms are not subject
+to the natural death that comes inevitably to man and the higher
+animals. It has been suggested that the debility of infusorians after a
+rapid series of divisions, and before conjugation, is to be interpreted
+as natural death. But the rejuvenescence that follows conjugation is
+incompatible with such an interpretation. Moreover, when conjugation
+does not occur, and the debility leads to death, the deaths must be
+regarded as accidental.
+
+The theory of the immortality of unicellular organisms is now generally
+accepted. However, there are animals, higher in the scale of life, to
+which natural death does not come. Among these occur certain forms of
+considerable complexity, composed of many organs and very many cells,
+such as many polyps, and some worms, especially annelid worms. Some
+annelids (Fig. 17) reproduce by transverse divisions very actively.
+“Throughout the summer,” said E. Perrier,[321] “the Naïdimorpha are
+devoid of genital organs, and apparently (according to unpublished
+observations of Maupas), they may be kept alive for several years, and
+perhaps indefinitely, in this sexless condition.” This certainly may be
+regarded as a case of immortality due to the indefinite power of
+regeneration possessed by a complex animal.
+
+The facts that I have cited show that death is not necessarily inherent
+in living organisms. Naegeli,[322] a well-known German botanist, has
+asserted even that natural death does not exist in nature. He points out
+that trees, more than a thousand years old, perish not by natural death,
+that is to say, by the gradual decay of their vitality, but by some
+catastrophe.
+
+[Illustration:
+
+  FIG. 17.—_Chætogaster_ about to divide into four (from a drawing by M.
+    Mesnil).
+]
+
+The age of the famous dragontree of the Villa Oratava at Teneriffe,
+admired by Von Humboldt, was estimated at several thousand years. Its
+trunk was hollow, but the huge monster continued to flourish until it
+was overthrown by a storm. It was only by a catastrophe that the
+long-lived giant perished. The Baobab is reputed to live for five or six
+thousand years.
+
+In a recently published essay, Jacques Loeb,[323] a distinguished
+biologist in Chicago, has made a study of natural death, and has come to
+the conclusion that there is no good evidence for its existence. He has
+observed that ripe, but unfertilised eggs of sea hedgehogs (Echini) die
+a few hours after they have been discharged. Loeb thinks that this may
+be a case of natural death, but I cannot agree with this opinion, as an
+egg that has not been fertilised by a spermatozoon may be compared with
+an organism deprived of its nutrition and so dying of starvation. In
+both cases death is purely accidental and could have been avoided.
+
+If natural death does exist, it must have appeared on the face of the
+earth long after the appearance of life. Weismann has suggested that
+death arose as an adaptation for the advantage of the species, that is
+to say, in relation to the surrounding conditions of existence, and not
+as an absolute necessity inherent in the nature of the living substance.
+He thought that as worn organisms are no longer suited for reproduction
+or for the struggle for life, natural death was due to natural
+selection, it being necessary to maintain the species in a vigorous
+state by weeding out the debased individuals. But the introduction of
+death for that purpose was superfluous, since the debility caused by old
+age in itself would eliminate the aged in the course of the struggle for
+existence. Violent death must have appeared almost as soon as living
+things came into being. The infusorians and other low organisms, despite
+their potential immortality, must have been subjected perpetually to
+violent death, falling victims to larger and stronger organisms. It is
+impossible to regard natural death, if indeed it actually exists, as the
+product of natural selection for the benefit of the species. In the
+press of the world natural death rarely could come into operation,
+because maladies or the voracity of enemies so frequently cause violent
+death.
+
+No doubt a certain number of deaths are recorded in statistics as being
+due to old age, without visible malady. Sometimes decrepit old men feel
+no pain and seem to fall quietly into their eternal sleep; but autopsy
+reveals serious lesions of the internal organs. There is reason to
+believe that even such deaths are in reality violent and are usually
+caused by infectious microbes. The general effect on the mind produced
+by examination of the collected facts is not an acceptance of the view
+that natural death is essentially inherent in living organisms, but the
+production of a wish to discover if there be any real proof of its
+existence.
+
+For some time natural death has been ascribed only to the parts of the
+body that are of use in the individual life. Those cells, the function
+of which is to secure reproduction of the species, are, like unicellular
+organisms, potentially immortal. The egg-cell of the female is
+transformed into a fœtus, and so is the starting-point of the new
+generation, while the sexual cells of the new generation give rise to
+the third generation, and so on, in an endless chain of life. The
+greater number, by far, of the eggs and spermatozoa perish; but their
+death is not natural but violent, being due to harmful external
+agencies. An infinitesimal minority of the sexual cells survive
+indefinitely in the successions of generations.
+
+Scientific proof exists, therefore, that our bodies contain immortal
+elements, eggs or spermatozoa. As these cells not only are truly alive
+but exhibit properties that are within the category of psychical
+phenomena, it would be possible to build up a serious thesis on the
+immortality of the soul.
+
+Observations on protozoa, and especially on the infusorian group of
+protozoa, show that these simple beings, each of which is composed of no
+more than a single cell, possess a high degree of sensibility. They
+select their food, distinguish living from dead animalculæ,[324] seek
+out their mates for conjugation, avoid danger, and hunt their prey; in
+fact, they are in possession of a set of qualities that must be included
+in psychical phenomena. Although such phenomena are very much lower in
+the case of the infusorians than in the case of higher animals, it is
+possible to speak of the soul of protozoa. Moreover, as the body is
+immortal by reason of its indefinite power of reproduction by division,
+the soul also of these creatures is immortal. However, the soul is so
+primitive that it is impossible to speak in definite terms about it.
+
+As the sexual cells of the human body are immortal, like the protozoa,
+the problem arises if these too be endowed with an immortal soul. Our
+existing knowledge makes it impossible to doubt that ova and spermatozoa
+have sensibility in a degree as high as that of the protozoa. The ova
+shed secretions that arouse the sensibility of the spermatozoa, and the
+latter, directed by this specific “odour” (the occurrence being known
+technically as chemotaxis), make their way to the ovum and penetrate it.
+Some substances, arousing the spermatozoa into activity and movement,
+attract them, others repel them. The phenomena of chemotaxis were shown
+for the first time in the case of cryptogams by Pfeffer, the
+distinguished botanist, and since then the male cells of many plants and
+different kinds of animals have been proved to possess sensibility.
+
+When ova and spermatozoa succeed in conjugating, they produce an
+individual of the next generation, to which they transmit what Haeckel
+has called the “cellular soul.”[325] This soul, then, is really
+immortal, inasmuch as the bodies of the reproductive cells are immortal.
+
+Although it is true that our bodies contain elements endowed with
+immortal souls, it by no means follows that our conscious souls are
+immortal. In an earlier chapter, I have already pointed out that the
+psychical phenomena of many of the cells of our body and the cellular
+souls of these are outside our consciousness. We have no consciousness
+of the perpetual battle waged by the phagocytes against the microbes
+that endeavour to obtain a foothold in our tissues. None the less the
+phagocytes are elements endowed with mobility and sensibility and
+possessing a cellular soul like that of the protozoa.
+
+A woman has no consciousness of the numerous spermatozoa, with their
+cellular souls, that enter her body, nor of those that fertilise her
+egg-cells; she is even without consciousness of the much more highly
+developed soul of the fœtus. A child before birth possesses psychical
+qualities much more numerous and more perfect than those of the
+reproductive cells. It is capable of responding to certain sensations
+and of performing movements. A child, in the later months of its
+prenatal existence, possesses the senses of touch and taste and, within
+limits, the sense of sight.[326] This soul is outside the consciousness
+of the mother. The mother cannot even tell by her consciousness if she
+bears under her girdle one or two embryonic souls. And so the
+immortality of the cellular soul has no relation to the problem of
+death.
+
+It is a common opinion that only the reproductive cells of man and
+animals are immortal, and that the other elements of the body are
+mortal, the latter, if they escape violence, dying a natural death. A
+contrast has been drawn between the mortal cells in which is resident
+the life of the body and the immortal cells on which the species
+depends. However, when non-reproductive cells possess the power of
+regeneration, it is impossible to deny their immortality. When a polyp
+or a worm reproduces by division, a large number of cells go to form the
+new individual, and these cells are immortal in the fashion of the
+infusoria.
+
+Immortal animals occur only among the lower invertebrates. The power of
+regeneration fades away in the higher ranks of the scale of life. Whilst
+worms may be divided in several pieces, each piece being capable of
+regeneration so as to form a new worm, when molluscs are cut they
+display only a limited capacity for regeneration. If the antennæ of a
+snail be amputated they will be renewed, but if the whole creature be
+cut in pieces death follows. Some of the lower vertebrates, such as
+newts and salamanders, can renew the tail and the limbs, but they cannot
+reproduce by division. Birds and mammals, the higher vertebrates, have
+very little power of regeneration, and tail and limbs are never reformed
+in their cases.
+
+It seems to be the case that the advance in the general organisation of
+animals has involved a loss in the reproductive capacity of the cells
+and tissues. Even in the highest animals, some organs, such as the
+liver, still possess regenerative capacity; but, on the other hand, many
+cells have lost the power of regeneration completely. The nervous cells,
+in particular, which are the highest and most perfectly organised
+elements of the body, cannot reproduce themselves. After their initial
+appearance in the course of embryonic development, they pass their lives
+without regenerating or reproducing. In acquiring the highest qualities,
+that is to say, their psychical activity, they have lost completely the
+power of reproduction, the distinctive feature of immortal cells. If
+cells doomed to natural death really exist, it is in the nervous tissues
+that we must look for them.
+

+  FIG. 18.—Ephemerids.
+]
+
+The existence of natural death in the animal world cannot be denied, but
+it is very rare. The best example is that of the curious insects known
+universally as ephemerids (Fig. 18). Swarms of these delicate and
+graceful insects are to be seen in the summer months round lights. The
+perfect insects emerge from water, in which the six-legged larvæ feed on
+the organic débris contained in fresh water. The larvæ are not
+predaceous, and escape from their numerous and hungry foes by agility.
+They are long-lived, some of them passing two or three years in the mud
+of streams, and in the end become winged insects after a rapid
+metamorphosis. Near Paris, anglers have a popular name (_manne_, manna)
+for one species (_Palingenia virgo_) which emerges in swarms after
+sundown from the waters of the Seine and Marne. The swarms fly in huge
+numbers, like heavy snow-flakes, for a very short time, and then fall
+into the water (Fig. 19). The flight of these insects lasts only an hour
+or two, and then, in an enfeebled condition, they fall down in vast
+numbers. They are attracted by the lanterns lighted by fishermen, and
+are collected to be used as bait. The life in the winged condition is
+truly ephemeral and lasts no more than a few hours. The structure of the
+insect is adapted to this short life. The larvæ have powerful jaws, used
+in the mastication of food; the winged insects possess only vestiges of
+jaws. They are unable to feed, and so are adapted only for the briefest
+existence. Their hour of aerial life is devoted to love. As soon as they
+emerge the males and females unite, and the packets of eggs, which are
+deposited at once, fall into the water, and in a few weeks the young
+larvæ hatch out.
+
+The mode of life and the organisation of the adult ephemerids show
+plainly that they are adapted to natural death. Death comes to them not
+because they are without food, or because the environment fails to
+provide something necessary to life, but merely because they emerge from
+the larval state in a non-viable condition, without the organs necessary
+to the maintenance of life.
+
+[Illustration:
+
+  FIG. 19.—Swarms of _Palingenia virgo_.
+]
+
+Once it is granted that natural death actually exists, it is necessary
+to study its mechanism as closely as the existing state of knowledge
+permits. To exclude the possibility of the death having to be
+interpreted as violent, it would be necessary to know that some very
+rapid infectious disease does not attack these insects as soon as they
+emerge from the water. This possibility, although remote, must be
+examined. Instances are known of large numbers of insects dying very
+rapidly as the result of attack by a species of mould which causes an
+epidemic. Every one has seen, especially in autumn, dead flies anchored
+to the window pane by a little tuft of white fluff. As so many
+individuals die about the same time, we might be disposed to assign the
+fact to natural death. The actual cause, however, is an infectious and
+fatal disease caused by a parasitic mould.
+
+The occurrence of some terrible epidemic may be excluded from
+consideration in the case of ephemerids. I have made investigations
+which show that such an epidemic does not occur. The bodies of the dying
+ephemerids contain no microbe which could be the cause of death. Their
+death must be regarded as natural, as the result of their organisation,
+as essentially a part of the nature of the insects. Among the cells of
+their body there are many active phagocytes. Is it possible to attribute
+death to ravages that these cells may cause among the higher cells and
+tissues? Microscopic examination, so far from supporting such a
+possibility, shows that the organs are quite normal in their intimate
+structure. The brain and central nervous system, the muscles and other
+organs, show no signs of that invasion by phagocytes found in cases of
+senile degeneration. In this example of natural death there is certainly
+no possibility of phagocytic intervention.
+
+Some biologists have suggested that the rapid death of ephemerids and of
+some other insects is due to debility caused by the great effort of
+depositing the male and female sexual cells. On this supposition, the
+case would be analogous to the shock which is sometimes the consequence
+of a surgical operation. This hypothesis, however, may be excluded, for
+among the dead ephemerids there are many males that have not united with
+females. Among ephemerids males are much more numerous than females;
+many males have no opportunity of undergoing the sexual shock and of
+emptying the reproductive organs, and these, none the less, die as
+rapidly as the others.
+
+As yet we do not know if all the tissues of the ephemerids die
+simultaneously in natural death. Most probably the cells of the nervous
+centres perish first, and so bring death on the others. The
+investigation ought to be made.
+
+Death comes to the ephemerids in the midst of love, at the moment when
+their sexual instincts are satisfied. It would be very interesting to
+know the sensations of these creatures as they feel death come on them
+in the act of reproduction. Naturally it would be impossible to obtain a
+full answer to the question, but many interesting facts regarding it may
+be ascertained. All the ephemerids, not only those the life of which is
+so brief, but those that live for several days (_Chloë_, for instance),
+are extremely easy to capture. It is unnecessary to take them unawares
+or to use a net as in the case of flies, wasps, and many other insects.
+Ephemerids may be taken with the fingers in the simplest way, because
+they offer no resistance and show no desire to escape, although they
+have six legs and two or four wings. This is not an isolated case, for
+some other insects (as, for example, winged ants and aphides) allow
+themselves to be captured with the same carelessness.
+
+Although the adult ephemerids are careless, the wingless larvæ are
+timid. When a tube is brought near them, among the water plants, with
+the object of capturing them, they rapidly move off. It often requires
+much patience and quickness to capture these larvæ (Fig. 20). The
+instinct of preservation of life displays itself by rapid flight.
+
+[Illustration:
+
+  FIG. 20.—Larva of an ephemerid (_Chloërufulum_).
+]
+
+It is remarkable that the adult insect has lost the instinct of
+self-preservation. If it be touched it may move a short distance off,
+but it does not take to flight although its wings are very large, and
+its body, which of itself weighs little, is still lighter because the
+digestive tube is filled with air and not with food. As a rule, an
+ephemerid that has been touched does not even move off, but allows
+itself to be captured without any resistance. It would not be accurate
+to say that the larva’s instinct of self-preservation has been replaced
+in the adult by an instinct for death; but it must be admitted that the
+instinct of preservation has been totally lost. The lack of resistance
+cannot be explained by any defect in the organs of sense. Not only are
+the eyes of the larval stage fully preserved in the adult, but the adult
+males have enormous eyes to enable them to recognise the female in the
+turbulent flight which takes place at the close of the day. Ephemerids
+of all ages possess well developed tactile organs, and it is thus in
+spite of a highly organised sensory system that the adults offer no
+resistance to enemies.
+
+It is no mere accident that the most striking examples of natural death
+occur among insects, for these creatures display an unusual stability in
+their cellular structure with a corresponding lack of the power of
+regeneration, in these particulars resembling man and the higher
+animals. The cells of the nervous system are very complex, and are well
+adapted for the highest function, that is to say, the psychical
+function. These highly endowed cells, however, are devoid of the power
+of reproduction. Many experiments have been made in relation to this,
+and it has been proved clearly that in cold-blooded vertebrates the
+brain and spinal cord with the nerve cells contained in them are capable
+of regeneration, whilst among mammals only extremely rare cases are
+known in which there has been any regeneration of the nervous elements.
+It is to be expected, then, that cases of natural death occur in the
+higher animals and especially in man. However, no case is known so plain
+as that presented by the ephemerids. I have already stated that of
+deaths apparently due to senile debility in man, a large proportion are
+certainly due to various infectious diseases that affect the old, such
+as pneumonia and nephritis. Close examination of the tissues confirms
+this conclusion, for the destruction of the higher elements by
+phagocytes produces what is really violent death and not a natural death
+like that of the ephemerids.
+
+Natural death in man is probably a possibility rather than an actual
+occurrence. Old age is not a true physiological process but exhibits
+many morbid characters. That being the case, it is not surprising that
+it seldom ends in natural death. It is probable, however, that natural
+death occasionally occurs in very old men.
+
+Attempts have been made to estimate the natural limits of human life.
+Flourens[327] based a calculation on the duration of the period of
+growth. If the latter be taken as one fifth the natural life, then human
+life ought to last a century. As centenarians are rare, the vast
+majority of deaths, which happen before that age has been reached, must
+be regarded as violent or accidental. The rule of Flourens, however, is
+arbitrary, and there is no evidence to show that it is exact. Probably
+in the human race, as in the case of ephemerids, the natural duration of
+life varies and cannot be expressed by a definite figure. In most cases
+it ought to be more than a hundred years, and only in rare cases ought
+it to be much less than that term. Probably there is a variation in the
+duration of life just as there is a variation of the date of sexual
+maturity for which rules may be laid down but not without anticipating
+numerous exceptions.
+
+The existing pathological character of old age vitiates all conclusions
+as to natural death, and it is still impossible to be exact in speaking
+of that subject. It is known that certain organs and tissues remain
+alive for some time after death. In the case of certain infectious
+diseases, the heart may be removed from a human body more than thirty
+hours after death, and if placed under proper conditions will renew its
+life, and beat for several hours. The white corpuscles, the spermatozoa
+and the cilia of a corpse, may retain their power of movement. Does this
+also happen in the rare cases of natural death? That question must be
+answered in the future. The most important question relating to natural
+death is the following: Is the appearance of natural death in man
+accompanied by the disappearance of one instinct, the instinct of self
+preservation, and by the appearance of another instinct, the instinct of
+death? Do the phenomena of the ephemerids give us any indication as to
+this? An exact answer is not to be expected. As old age is generally
+what may be called an unnatural phenomenon, it is extremely rare for
+persons to approach the age of natural death with their faculties
+unclouded. I have had under observation a centenarian old woman, who
+still remembered some incidents of her youth; in her the desire to live
+was still strong, but her intellectual faculties were partially dim.
+Moreover, her brain, of which I have already spoken (p. 241), showed a
+marked degeneration of the nerve cells due to the activity of
+macrophages.
+
+I have obtained much information about a centenarian who was alive in
+Rouen in 1900, but a single glance at her photograph was enough to show
+that she no longer was in full possession of intelligence.[328] She was
+infirm in many ways. So also, Chevreul, the celebrated chemist, who died
+at the age of one hundred and three years, showed not the faintest wish
+for death; he clung to life, but his mental powers had grown weak.
+
+The cases to which I have referred are typical, but there are exceptions
+worthy of close attention. Tokarski, in the essay on the fear of death,
+to which I referred in the sixth chapter, quoted the case of a female
+centenarian who stated as follows: “If you come to live as long as I
+have lived, you will understand not only that it is possible not to fear
+death, but to feel the same need for death as for sleep.” A new feeling
+had come into existence in the very old person, a feeling
+incomprehensible to those less old. Apparently this was a case in which
+the instinct of natural death had appeared in a centenarian whose mental
+faculties had been retained in a sufficiently perfect state.
+
+I wish very much that I had myself been a witness of this old woman’s
+remarkable instinct in even one case of the many that I have observed.
+But all that have been pointed out to me as subject to this new desire
+have turned out to have been possessed of very different ideas. Some
+were old invalids, weary of pain and ready to exchange the sorrows of
+life for death, but who would have preferred to be healed and to live on
+in comfort. When the possibility of recovering health was suggested to
+them, they showed signs of pleasure and of the renewal of hope.
+
+Investigations that I have made in homes for the aged have led to
+negative results on this subject. No case showed the slightest sign of
+the approach of the instinct of death. However, I have learned from Dr.
+Fauvel of one case to add to the instance noticed by Tokarski. It was
+the case of an old lady whose health and circumstances were comfortable
+and who before her death showed a real desire for it and stated it in
+much the same language as that quoted by Tokarski. In Fauvel’s case,
+however, the old lady had reached the age of only eighty-five years. It
+seems probable that this was a second genuine case of the appearance of
+the instinct of death, and it is therefore interesting to notice that
+that instinct, like the sexual instinct, is subject to variation in the
+date of its appearance.
+
+In my search for instances of the instinct of death, I made use of the
+large collection made by Lejoncourt,[329] but found that the information
+given by this author was very incomplete as to the mode of life and the
+last moments of his cases.
+
+The Bible testifies to the frequency of old age in ancient times and to
+the complete preservation of the faculties in the aged. It also contains
+some references that may be interpreted as instances of the instinct of
+death. I may take its account of the death of some of the patriarchs.
+“And these are the days of the years of Abraham’s life which he lived,
+an hundred threescore and fifteen years. Then Abraham gave up the ghost,
+and died in a good old age, an old man, and _full of years_.”[330] “And
+the days of Isaac were an hundred and fourscore years. And Isaac gave up
+the ghost, and died, and was gathered unto his people, being old and
+_full of days_: and his sons Esau and Jacob buried him.”[331] “After
+this lived Job an hundred and forty years, and saw his sons, and his
+sons’ sons, even four generations. So Job died, being old and _full of
+days_.”[332] It is probable that the phrase “old and full of days,”
+which sounds strange in our ears, simply refers to the instinct of
+death, developed in well preserved old men who had attained ages of from
+140 to 180 years.[333] The Biblical phrase is not merely a commonplace
+phrase applied to the death of celebrities for the references to deaths
+of other persons were put in different language. “And these are the
+years of the life of Ishmael, an hundred and thirty and seven years: and
+he gave up the ghost and died; and was gathered unto his people.”[334]
+“And Jacob lived in the land of Egypt seventeen years: so the whole age
+of Jacob was an hundred forty and seven years.”[335] “And Aaron was an
+hundred and twenty and three years old when he died in Mount Hor.”[336]
+“And Moses was an hundred and twenty years old when he died; his eye was
+not dim, nor his natural force abated.”[337] In only one of these later
+cases had the individual reached the age of one hundred and forty years,
+at which age, apparently, the instinct of natural death appeared.
+
+It may seem altogether surprising and improbable to us that an instinct
+for death should arise in man, since we are imbued with an instinct of
+an opposite nature. From the facts that I collected in my sixth chapter,
+it was to be inferred plainly that the desire of life and the fear of
+death are manifestations of an instinct deep-rooted in the constitution
+of man. That instinct is of the same order as the instincts of hunger
+and thirst, of the need of sleep, of movement and of sexual and maternal
+love. The devotion and care bestowed on their young by female birds and
+mammals are known universally. And yet these instincts can be reversed.
+There is no sacrifice of which the mothers are not capable if it serve
+to save the life or promote the well-being of their offspring. Such
+devotion is a manifestation of the maternal instinct, which is one of
+the strongest instincts known to us. And yet that love, so tender and so
+absolute, lasts only for the time during which the wants of the young
+need to be satisfied. As soon as the young begin to be independent, the
+maternal love changes to indifference or to dislike. At the next
+breeding-period, maternal love reappears again, so that there is a
+periodic ebb and flow of the instinct.
+
+The new-born babe takes an instinctive delight in the milk of his
+mother, which seems to him the only good food in the world. As soon as
+he can show his feelings, his intense satisfaction as he is suckled is
+plain. But this instinct lasts only during the period of lactation. As
+soon as the child begins to take different kinds of food, he ceases to
+be pleased with his mother’s milk, and may dislike it for the remainder
+of his life. Several adults to whom I have offered human milk would not
+even taste it, so disgusting did it seem to them. And yet the taste had
+nothing intrinsically disagreeable in it. Here again is an example of a
+strong instinct that changes completely.
+
+Children often eat to repletion of some kind of substance, and for long
+afterwards that substance disgusts them instead of being coveted by
+them. It is said that apprentices to pastry-cooks and makers of
+sweetmeats are allowed at first to eat as much as they please. They soon
+come to have a profound dislike for the sweet things that children like
+so much.
+
+A mother who adores her child, or a child who is extremely fond of
+sweetmeats cannot understand how any mother could dislike her offspring
+or any apprentice have a distaste for sweets. In the same way, human
+beings full of the desire for life, believe more easily in eternal life
+than in the possibility of an instinct of death. And yet the instinct of
+death seems to lie, in some potential form, deep in the constitution of
+man. If the cycle of human life followed its ideal course according to
+physiological function, then the instinct of death would appear in its
+time, after a normal life and an old age healthy and prolonged.
+
+In reality, human life is subject from its very beginning to the
+pernicious disharmonies in the constitution of man. This evil influence
+increases with the passing of the years and leads to an old age ruined
+by abnormalities. It is not surprising that under such circumstances men
+wish neither to grow old nor to die. Old men, in spite of their
+attachment to life, do not attain the capacity to know all that is good
+in it, and die, in the fear of death, without having known the instinct
+of death. They may be compared with unhappy women who have married
+before their sexual instincts have awakened and who have died in
+childbirth, without ever having known the real joy of loving. Formerly,
+the number of women in such a case was large. In some parts of
+Abyssinia, girls married when they were still very young and before
+their physical development was mature. According to Hassenstein,[338]
+nearly one third of these young women died in childbirth. They quitted
+life before they had known the true sexual instinct. The advancement of
+civilisation and of medical knowledge has greatly reduced the number of
+such unhappy women. We must hope that the progress of knowledge will
+bring about a similar advance in relation to the instinct of death. With
+that progress, the number of men who will live until the instinct has
+been attained will become greater and greater.

+
+
+Man, who is a descendant of some anthropoid ape, has inherited a
+constitution adapted to an environment very different from that which
+now surrounds him. Man is possessed of a brain very much more highly
+developed than that of his ancestors, and has entered on a new path in
+the evolution of the higher organisms. The sudden change in his natural
+conditions has brought about a large series of organic disharmonies
+which become more and more acutely felt as he becomes more intelligent
+and more sensitive. And thus there has arisen a number of sorrows which
+poor humanity has tried to relieve by all the means in its power. The
+disharmonies in the sexual functions have brought into existence
+attempted remedies of the strangest kind. The greatest disharmony of the
+constitution is that of the morbid nature of old age and the
+impossibility of reaching the instinct of natural death; this has
+produced childish and erroneous conceptions of the immortality of the
+soul and of the resurrection of the body, and many other strange
+doctrines that have been imposed upon us as revealed truth.
+
+Human intelligence, in the course of its progressive evolution, has
+rebelled against these naïve palliatives. Finding the restoration of the
+much-desired harmony beyond its power, humanity became resigned to a
+passive fatalism, and believed even that the existence of man was a kind
+of bad joke, a _faux pas_ in the evolution of sentient organisms. Exact
+science, developing slowly, but surely, has at last tried to master the
+situation. Moving step by step, passing from the simple to the complex
+and from the particular to the general, science has established a set of
+truths which all the world must accept.
+
+Humanity in its misery has put question after question to science, and
+has lost patience at the slowness of the advance of knowledge. It has
+declared that the answers already found by science are futile and of
+little interest. From time to time it has preferred to turn back, and to
+delude itself with the beautiful mirages offered by religions and
+systems of philosophy.
+
+But science, confident of its methods, has quietly continued to work.
+Little by little, the answers to some of the questions that have been
+set have begun to appear. Whence do we come? science has been asked
+unceasingly. Is not man a being unlike other beings, made in the image
+of God, animated with the divine breath, and immortal? No, science
+answers. Man is a kind of miscarriage of an ape, endowed with profound
+intelligence and capable of great progress. His brain is the seat of
+processes that are very complex, and much higher than those of other
+animals, but these functions are incompatible with the existence of an
+immortal soul.
+
+Whither are we going? That question above all other things has absorbed
+the attention of man, and naturally so, for it is less important to know
+our origin than to know our destiny. Does death mean absolute
+extinction, or is it a gateway leading to a new and everlasting life?
+And if the latter alternative be untrue, how are we to face inevitable
+death?
+
+Science cannot admit the immortality of the conscious soul, for
+consciousness is a function of special elements in the body that
+certainly cannot live for ever. Immortality exists only for very low
+organisms that renew their lives by repeated divisions with complete
+regeneration, and that have no highly developed consciousness.
+
+Death brings absolute extinction, and it seems unbearable because of the
+condition in which it surprises us. It comes before man has finished his
+physiological development, and when the instinct of life is still
+strong.
+
+Ever since man has begun to look a little beyond his daily and immediate
+wants, he has asked if there be a goal for his life, and what that goal
+may be. As he has generally failed to find such a goal, he has gone the
+length of believing life to be a mere accident, and of thinking it idle
+to seek a goal. He has formed depressing and pessimistic conclusions.
+Humanity may be compared to a boy that has not yet acquired the sexual
+instinct, but has asked the meaning of the reproductive organs. As these
+organs play no part in the functions of his life, he might easily think
+their existence not only absolutely useless but absurd.
+
+Man, because of the fundamental disharmonies in his constitution, does
+not develop normally. The earlier phases of his development are passed
+through with little trouble; but, after maturity, greater or lesser
+abnormality begins, and ends in old age and death that are premature and
+pathological. Is not the goal of existence the accomplishment of a
+complete and physiological cycle, in which occurs a normal old age
+ending in the loss of the instinct of life and the appearance of the
+instinct of death.
+
+The pessimistic school has often spoken of death as the true goal of
+human life. Schopenhauer,[339] for instance, said: “Death must really be
+regarded as the true goal of life; when it comes it at once adjusts all
+that has been preparing in the course of life.” Baudelaire[340] has
+exactly the same idea in his verse:
+
+         “C’est la mort qui console, hélas! et qui fait vivre;
+         _C’est le but de la vie_, et c’est le seul espoir
+         Qui, comme un élixir, nous monte et nous enivre
+         Et nous donne le cœur de marcher jusqu’au soir.”
+
+“Alas! it is death that comforts and gives us life; it is the goal of
+our days, it is our only hope that like a wine goes to our head and
+makes us drunk, and puts heart into us to journey on till the night.”
+
+The normal end, coming after the appearance of the instinct of death,
+may truly be regarded as the ultimate goal of human existence. But
+before attaining it, a normal life must be lived: a life filled all
+through with the feeling that comes from the accomplishment of function.
+Knowledge of the true goal of life clears up the problem and shows us
+the right conduct of life. In my first chapter, I tried to lay before
+the reader a summary of the views that have been held as to right
+conduct. Ever since the attempt has been made to discover a rational
+basis of morality, human nature, regarded essentially as good, has been
+taken as that basis. Religions and systems of philosophy, on the other
+hand, which have tried to find another foundation for morality, have
+regarded human nature as vicious at the roots. Science has been able to
+tell us that man, the descendant of animals, has good and evil qualities
+in his nature, and that his life is made unhappy by the evil qualities.
+But the constitution of man is not immutable, and perhaps it may be
+changed for the better.
+
+Morality should be based not on human nature in its existing vitiated
+condition, but on human nature, ideal, as it may be in the future.
+Before all things, it is necessary to try to amend the evolution of the
+human life, that is to say, to transform its disharmonies into harmonies
+(_Orthobiosis_). This task can be undertaken only by science, and to
+science the opportunity of accomplishing it must be given. However, even
+in the most civilised countries, science is far from being in this ideal
+condition. Obstacles lie in its way and retard its advance.
+
+To make the human constitution better, it would be necessary to know it
+thoroughly. How can we try to transform to a normal and physiological
+condition old age, at present utterly pathological, unless we first
+understand the most intimate details of its mechanism? Deeply rooted
+prejudices make it very difficult to examine the organs of the aged
+dead. The difficulties surrounding post-mortem investigations are almost
+insurmountable. According to the regulations enforced in France,
+autopsies cannot be made until twenty-four hours after death. An autopsy
+cannot be made except when the corpse has not been claimed by any
+relatives in the direct line, husband or wife, brothers, sisters,
+uncles, aunts, nephews, nieces. If kinsmen put in no claim, co-operative
+societies may take possession of the corpse and oppose the holding of an
+examination. Even when an examination has been permitted, it must extend
+only to “the ascertaining of exact facts, and this must be taken as
+excluding the mutilation of the corpse by the removal of any organ or
+portion of the anatomy, however interesting scientifically such material
+might be.” (Circular of the Director of “Assistance publique,” January
+20, 1900.[341]) It is easy to see that such regulations make extremely
+difficult the investigation of senile degeneration, and the search for
+means of preventing it, especially by the use of serums obtained after
+injecting emulsions of human organs. These difficulties in reality arise
+from the prejudice in favour of the existence of a life beyond the grave
+and a resurrection of the body.
+
+Almost similar difficulties stand in the way of obtaining the bodies of
+old animals. Their owners prefer to keep animals, after they are
+useless, until they die, and to bury the bodies instead of devoting them
+to the scientific investigation that is so important to humanity.
+
+As soon as we come to believe that the solution of the problems of human
+happiness will come not from religions nor from systems of metaphysical
+philosophy, but from exact science alone, the obstacles to progress will
+be removed. That scientific methods will redress the disharmonies of the
+human constitution is the more probable inasmuch as the old age of human
+beings was more physiological, and their death more natural, in earlier
+times than they are to-day.
+
+The study of the human constitution not only denotes the real goal of
+our existence, but indicates to us what is meant by true culture and
+real progress.
+
+In earlier chapters, I have shown that philosophers have recognised the
+existence in man of a tendency to culture and progress. But what do they
+mean by these two words? Attempts have been made to define them as
+clearly as possible, and Herbert Spencer, the greatest of living
+philosophers, has devoted a special essay to the subject. He examined
+those phenomena that he regarded as progressive, first in the inorganic
+world, next, in the world of living things, and, finally, in humanity.
+He regards as progressive only the changes that tend to increase human
+happiness, and it is precisely on account of that tendency that he
+regards them as progressive. In order to define progressive phenomena
+Spencer thinks it necessary to make parallel studies of them in man and
+the animal world. He finds that progress is marked always by a
+transformation from the simple and uniform to the complex; and that it
+produces constant differentiation, in the evolution of the planetary
+world, in the embryonic development of the individual, and in the
+societies of men and animals. But differentiation is not a complete
+account of progress, for in the latter must be included the change of
+the indefinite into the definite. Spencer identifies progress with
+evolution, and his well-known definition of evolution is, that it is “an
+integration of matter and concomitant dissipation of motion; during
+which the matter passes from an indefinite, incoherent homogeneity to a
+definite, coherent heterogeneity; and during which the retained motion
+undergoes a parallel transformation.” Such a formula embraces too much,
+so that he is rather vague, especially when he applies it to human
+affairs. Differentiation in itself is not the whole of progress. It is
+necessary in each concrete case to inquire into its limits and
+modifications.
+
+The application of his theory of progress and evolution led Spencer, in
+his investigation of the basis of morality, to define human progress as
+the tendency towards a life as full and as long as possible. By fulness
+he means complexity, if I interpret his argument correctly. Civilised
+life as compared with savage life, is a realisation of progress.
+Civilised man, according to Spencer, uses food in a better regulated
+fashion, in accordance with the call and degree of his appetite; the
+food is of better quality, it is freed from contamination, is much more
+varied and is better prepared. The same differentiation distinguishes
+the clothing, the homes and so forth of civilised man. According to
+Spencer, all such progress helps real happiness, that is to say the
+fulness and the prolongation of life.
+
+It is easy to see, however, that such an interpretation of progress is
+inexact, like the conception of the goal of life associated with it. If
+the complication of the mode of life, which is so marked in modern
+civilisation, is really the best way of reaching happiness, there are no
+reasons to arrest the tendency in that direction. If, on the other hand,
+my view be correct, that true progress consists in the elimination of
+the disharmonies of human nature and in the cultivation of physiological
+old age followed by natural death, the conditions for realising progress
+would be different and very clear. The great complexity of life in
+modern civilisation is a sign of progress according to Spencer, but I do
+not agree with him. Spencer speaks of the variety and preparation of
+food. It is certain that this complexity militates against physiological
+old age, and that the simpler food of uncivilised races is better. I do
+not wish to write an essay on domestic hygiene, and I shall be content
+with saying that most of the delicate dishes provided in the homes,
+hotels, and restaurants of the rich, stimulate the organs of digestion
+and secretion in a harmful way. It would be true progress to abandon
+modern cuisine and to go back to the simple dishes of our ancestors. One
+of the conditions that enabled the Jews of the earlier Biblical times to
+live longer than civilised people, was, beyond all doubt, the greater
+simplicity of their diet. True hygiene, which is in open disagreement
+with the elaborated art of cookery, is also opposed to the
+differentiation of modern dress and dwellings. Progress thus would
+consist in simplifying many sides of the lives of civilised people.
+
+The luxury which has done so much harm to mankind, and which would be
+included in the formula, “passage from indefinite homogeneity to
+definite heterogeneity,” is founded not on a general law of evolution of
+the whole universe, but on a particular conception of life, quite
+different from mine according to which the rectifying of the abnormal
+human cycle to a normal cycle is the true goal of life.
+
+Perhaps one of the oldest conceptions of life that has tended to luxury
+is to be found in the book of Ecclesiastes. Having reached the
+conclusion: “For in much wisdom is much grief: and he that increaseth
+knowledge increaseth sorrow” (i. 18), and having said: “Then I beheld
+all the work of God, that a man cannot find out the work that is done
+under the sun: because though a man labour to seek it out, yet he shall
+not find it, yea farther; though a wise man think to know it, yet shall
+he not be able to find it.”[342] Solomon laid down the rules of life as
+follows: “Go thy way, eat thy bread with joy, and drink thy wine with a
+merry heart: for God now accepteth thy works.”
+
+“Let thy garments be always white; and let thy head lack no ointment.”
+
+“Live joyfully with the wife whom thou lovest all the days of the life
+of thy vanity, which he hath given thee under the sun, all the days of
+thy vanity; for that is thy portion in this life, and in thy labour
+which thou takest under the sun.”
+
+“Whatsoever thy hand findest to do, do it with thy might; for there is
+no work, nor device, nor knowledge, nor wisdom, in the grave, whither
+thou goest.”[343]
+
+The wisdom of Solomon was to enjoy this life as much as possible, since
+man is unable to solve the problem of the goal of life. His precepts
+have been taken as a guide, and have led to an organisation of life that
+could only become more and more epicurean.
+
+As soon as the goal of life has been seen clearly, luxury ceases to be
+true happiness as it hinders the making perfect of the normal cycle of
+human life. Young people, instead of abandoning themselves to all the
+pleasures because they have nothing before them but a sad prospect of
+morbid old age and death, ought to make ready for physiological old age
+and natural death. The apprenticeship certainly will be long. In our
+time the years of study already last much longer than occurred even a
+century ago. As the body of knowledge grows greater, the time to acquire
+it will become prolonged, but this period of preparation will serve as
+the prelude to ripe maturity and ideal old age.
+
+Old age is repulsive at present, because it is an old age devoid of its
+true meaning, full of egoism, narrowness of view, incapacity and
+malignancy. The physiological old age of the future assuredly will be
+very different. In the societies of animals, especially as they occur
+among insects, the members show a high degree of differentiation. Some
+individuals are adapted to the reproductive functions, while others are
+sterile and are fitted for the care of the young and to supply the wants
+of the community. This differentiation, which is of social value, has
+arisen independently in different groups. Thus, in the societies of bees
+and ants the workers are sterile females, while in the case of termites,
+individuals of both sexes may be sterile. In the human race, evolution
+is following another path. There is no sign of the appearance of a
+sterile class; but, as the life of man is longer than that of insects,
+it is divided into two periods, a reproductive period and a sterile
+period. Old age, at present practically a useless burden on the
+community, will become a period of work valuable to the community. As
+the old man will no longer be subject to loss of memory or to
+intellectual weakness, he will be able to apply his great experience to
+the most complicated and the most delicate parts of the social life.
+
+Young men are usually very bad politicians, and in countries where they
+take a large share in public affairs they do much harm because they are
+without the necessary practical knowledge. Their incapacity is clearly
+shown by the great changes in their political views as they advance in
+years and gain experience. In the future, old men will have charge of
+all complex and difficult social functions. Thus, vast improvements will
+be made in politics and in justice, which at present are defective
+because of their insufficient foundations.
+
+As soon as every one has recognised the true goal of human life, and has
+assumed, as the ideal, the realisation of the normal cycle of life, a
+real guide to life will have been found. We shall know at least whither
+we are going, and as yet we are ignorant of that. We have wished to make
+life better, but we have not known how or for whom to make the attempt.
+Formerly it was assumed that, in the future, love would spread and
+become generalised. Family love had spread to the tribe and then had
+been transformed to patriotism; it was held that no obstacle stood in
+the way of its embracing all humanity. Such an idea was prevalent in the
+eighteenth century, and became a common ground of all systems of
+philosophy, morality and politics. But, since means of communication
+have been improved so vastly and since the most distant voyages are
+within the power of almost every one, the vague notion of “humanity” has
+been replaced by exact knowledge of the native savages in many parts of
+the earth. We have come to disbelieve in “humanity” in the old sense of
+the word, so great is the difference between savage and civilised
+peoples. And many modern theories have rejected the inclusion of the
+lower races in the sentiment of humanity. In the fifth chapter, I quoted
+the view of the moralist, Sutherland, on the advantages that have come
+about from the English seizure of the forests that belonged to the
+natives of Australia. Moreover, it is well known that a profound hatred
+exists between white men and black men in several parts of the earth,
+notably in America and the Antilles. Such instances could be multiplied.
+
+How then are we to emerge from this difficulty? At what point is the
+love of the future to be stayed, if it cannot spread to all humanity?
+
+In a recently published treatise on natural philosophy, Ostwald,[344] a
+very distinguished German physical chemist, has discussed this question.
+He calls good “the actions that made easier the existence of other men.”
+But to what other men are we to apply this rule? “What is the size of
+the circle of altruistic love,” asked Ostwald. “The general feeling,” he
+said, “is that it should cover the family and the nation. The feeling
+that it should cover all humanity appears to most of us as a theoretical
+demand rather than something practical. And thus have not most of us the
+tendency to limit our altruistic actions much more in the case of men
+beneath us than in the case of our social comrades (Stadesgenossen)?”
+According to this formula, moral action would not stretch beyond our
+compatriots, and humanity as a whole would be excluded from it.
+
+Here we have entered on a problem relating to the principles of normal
+life. In former times, religion was the chief bond among men. Later on,
+religion gave way to patriotism, which in default of anything better
+still holds its place. Community of language unites the individuals of a
+nation, but the advance of civilisation has undermined the foundation of
+that source of differentiation. Naturally, when a number of men spoke
+only one and the same language, great solidarity was the result, as
+ideas spread only by language. But such a monoglottism is not the end of
+human progress. As means of communication have improved, the nations
+have been brought in contact with each other. The knowledge of foreign
+languages is an elementary necessity of modern life. And so the bonds of
+nationality certainly will become looser, in this respect following the
+bonds of family. The dislike that we have to people whose language we do
+not understand, becomes changed into a feeling of unity with them as
+soon as we can understand them. In that respect an active development is
+in progress, and we shall have to seek out some new principle on which
+to base international solidarity. A good deal has been made of the
+possession by different nations of the same culture, but the vagueness
+of the phrase has not been realised. Recognition of the true goal of
+life and of science as the only means by which that goal may be attained
+would form an ideal on which men might unite; they would group
+themselves around that, as in former days men were held together by
+religion.
+
+I think it extremely probable that the scientific study of old age and
+of death, two branches of science that may be called _gerontology_ and
+_thanatology_, will bring about great modifications in the course of the
+last period of life. All that we know on these subjects confirms my
+view. But will it lead to the development of an instinct of death? That
+instinct lies deep in the roots of the human constitution? Will the
+means be found to bring it to the surface? Has not the enormous period
+during which it has remained latent led to its atrophy? The science of
+the future alone can answer that question. But the persistence of organs
+and structures that are extremely ancient, as for instance, the survival
+of the mammary glands in males and of the vermiform appendage in
+anthropoid apes and man, gives us the hope that the instinct of natural
+death may emerge from its latent condition when old age has become a
+normal process.
+
+The mammary glands of males are functionless rudiments. They must be
+interpreted as vestiges of organs that were more highly developed in
+remote ancestors among which both sexes gave milk to nourish the young.
+This function exists in a latent condition in the males of living
+mammals. Extremely rare cases have existed in which males possessed
+large glands secreting enough milk to feed the young. These males, it is
+true, had the genital organs either very badly developed or in a
+condition approaching hermaphroditism.[345] But in other authentic cases
+(perfectly developed) he-goats and rams have been known to provide milk
+in considerable quantities, whilst married men have suckled children
+with milk secreted by unusually developed glands. It is stated that the
+secretion of milk can be excited by stimulation of the nipples.[346]
+Such examples of the reappearance of a latent property that has been
+lost for untold ages are extremely important.
+
+Probably actual cases of the instinct of natural death in man are as
+rare as instances of the secretion of milk by males. But favouring
+circumstances and some education of the instinct of death would probably
+reawaken it and develop it fully. There is much work to be done before
+so great an object can be achieved. But it is the peculiar feature of
+science to be eager for much labour, while religions and systems of
+metaphysical philosophy are content with passive fatalism and silent
+resignation. The mere hope of being able to solve the great problems of
+humanity in the more or less distant future brings much satisfaction.
+When Tolstoi, agonised by the impossibility of solving the great
+problems, and haunted by the fear of death, asked if the love of our
+children is not able to sooth our souls, he found that such a hope was
+vain. “What is the good,” he said, “of rearing children who will soon
+find themselves in the same difficult position as their parents?” “Why
+should they live? why should I love them and protect them and foster
+them? Is it that they may come to the same despair as I am in myself or
+else grow imbecile? As I love them, I do not wish to hide the truth from
+them, for each step in knowledge will lead them nearer to it. But the
+truth is—death.” I can understand that many persons would abstain from
+having children if they had come to these pessimistic conclusions.
+
+The point of view that I have exposed in this book will make life more
+possible. Our generation has no chance of attaining physiological old
+age and normal death; but it may take real consolation from the thought
+that those who are now young may advance several steps in that
+direction. It may reflect that each succeeding generation will get
+closer and closer to the solution and that true happiness one day will
+be reached by mankind.
+
+The slow advance to happiness will demand many sacrifices. Already, men
+of science sacrifice their health and sometimes their life to reach the
+solution of some important problem, as for instance, to clear up a
+medical question, and so be ready to heal or to save the lives of their
+fellows.
+
+Before it is possible to reach the goal, mankind must be persuaded that
+science is all-powerful and that the deeply rooted existing
+superstitions are pernicious. It will be necessary to reform many
+customs and many institutions that now seem to rest on enduring
+foundations. The abandonment of much that is habitual and a revolution
+in the mode of education will require long and painful effort.
+
+Definition of the goal of human existence will bring great precision to
+the principles of morality. True policy will have to be reared on new
+foundations. The politics of to-day are in the condition in which
+medicine still remained in days long past. In the old days any one was
+allowed to practise medicine, because there was no medical science and
+nothing was exact. Even at the present time, among less civilised
+people, any old woman is allowed to be a midwife. In some cases the
+mother attends the labour of her daughter, or (as for instance in a
+caste of natives in Malabar), it may be the mother-in-law who does the
+duty. Very often friends act as midwives. Among more civilised races,
+differentiation has taken place, and childbirths are attended by women
+of special training, who are midwives by diploma. In the case of nations
+still more civilised, the trained midwives are directed by obstetric
+physicians who have specialised in the conducting of labour. This high
+degree of differentiation has arisen with, and has itself aided, the
+progress of obstetric knowledge.
+
+Politics, as they exist to-day, correspond to the early stages of
+obstetric practice. Every adult male is thought fit for exercising
+functions so difficult as those of an elector or a juryman. The only
+excuse for this condition is that political science is in its infancy.
+When sociology is more advanced, there will come about a differentiation
+like that in medicine. When that has taken place, old persons who have
+acquired great experience, and who because of their physiological
+constitutions have preserved all their faculties, will give most
+valuable services to the society of the future.
+
+In the progress towards the real goal of life, men will lose much of
+their liberty, but will receive in exchange a new feeling of solidarity.
+As knowledge becomes more and more extensive and exact, freedom to
+neglect it will be more and more limited. Formerly any one was at
+liberty to teach that whales were fish; but now that it has been proved
+that whales are mammals, the mistake is not to be pardoned. Since
+medicine has become more of an exact science, the liberty of doctors has
+been restrained. Practitioners have already been sentenced for
+neglecting antisepsis and asepsis. Other forms of freedom, such as the
+freedom to neglect vaccination against smallpox, to spit on the floor,
+or to let dogs run loose without being muzzled, are worthy of savage
+days and will cease as civilisation advances.
+
+On the other hand, the knowledge that the goal of human life can be
+attained only by the development of a high degree of solidarity amongst
+men will restrain actual egotism. The mere fact that the enjoyment of
+life according to the precepts of Solomon is opposed to the goal of
+human life will lessen luxury and the evil that comes from luxury.
+Conviction that science alone is able to redress the disharmonies of the
+human constitution will lead directly to the improvement of education
+and to the solidarity of mankind.
+
+In progress towards the goal, nature will have to be consulted
+continuously. Already, in the case of the ephemerids, nature has
+produced a complete cycle of normal life ending in natural death. In the
+problem of his own fate, man must not be content with the gifts of
+nature; he must direct them by his own efforts. Just as he has been able
+to modify the nature of animals and plants, man must attempt to modify
+his own constitution, so as to readjust its disharmonies.
+
+Breeders form a conception of the ideal result when they are about to
+attempt the production of some new variety which shall be pleasing
+esthetically and of service to man. Next, they study the existing
+individual variations in animals and plants on which they wish to work,
+and from which they will select with the minutest care. The ideal result
+must have some relation to the constitution of the organisms selected.
+
+To modify the human constitution, it will be necessary first, to frame
+the ideal, and thereafter to set to work with all the resources of
+science.
+
+If there can be formed an ideal able to unite men in a kind of religion
+of the future, this ideal must be founded on scientific principles. And
+if it be true, as has been asserted so often, that man can live by faith
+alone, the faith must be in the power of science.

+
+This work deals with the problem of personality, especially as raised by
+William James and M. Bergson. If a man imagines himself bound, in
+deference to science or psychology, to deny the existence of
+personality, he commits himself to saying “I do not exist.” If he
+shrinks from that absurdity, he must accept personality as a reality: a
+person is both a subject who knows others and an object of others’
+knowledge. The bond, however, which holds persons, human and divine,
+together, cannot be merely intellectual: it must be emotional as well as
+intellectual—the bond of love.

+
+The author here states the general results of the extended studies in
+genetic and social science and anthropology made by him and others, and
+gives a critical account of the history of the interpretation of nature
+and man, both racial and philosophical.
+
+The book offers an _Introduction to Philosophy_ from a new point of
+view. It contains, also, a valuable glossary of the terms employed in
+these and similar discussions.

+necessarily referred to in tracing the evolution of geography as a
+department of science. The author hopes that in the attempt to tell the
+story of the evolution of geography up to the present day, it will be
+evident that it is as amenable to scientific methods as any other
+department of human knowledge, and that it performs important functions
+which are untouched by any other line of research.

+
+The author considers a subject, the solution of which offers more
+enticement to the well-wisher of the race than the gold of the Incas did
+to the treasure-seekers of Spain, who themselves doubtless looked upon
+the coveted yellow metal, however mistakenly, as a key to the happiness
+which all are trying to find. “Amid the noisy tumult of life, amid the
+dissonance that divides man from man,” remarks M. Finot, “the Science of
+Happiness tries to discover the divine link which binds humanity to
+happiness through the soul and through the union of souls.” The author
+considers the nature of happiness and the means of its attainment, as
+well as many allied questions.

+</div>
+
+<p class='c006'>When Pasteur died a remarkable article appeared in one of
+the Paris newspapers. The writer described the intimate
+routine of the life at the Pasteur Institute, and compared it
+with that of a mediæval religious community. A little body
+of men, forsaking the world and the things of the world,
+had gathered together under the compulsion of a great idea.
+They had given up the rivalries and personal interests of
+ordinary men, and, sharing their goods and their work, they
+lived in austere devotion to science, finding no sacrifice of
+health or money, or of what men call pleasure, too great for
+the common object. Rumours of war and peace, echoes of
+the turmoil of politics and religion, passed unheeded over
+their monastic seclusion; but if there came news of a strange
+disease in China or Peru, a scientific emissary was ready with
+his microscope and his tubes to serve as a missionary of the
+new knowledge and the new hope that Pasteur had brought
+to suffering humanity. The adventurous exploits and the
+patient vigils of this new Order have brought about a revolution
+in our knowledge of disease, and there seems no limit
+to the triumphs that will come from the parent Institute in
+Paris and from its many daughters in other cities.</p>
+
+<p class='c007'>Élie Metchnikoff, now Professor at the Pasteur Institute
+in Paris, is one of the most distinguished of the disciples
+who left all else to follow Pasteur. He was born on the
+third (16) May, 1845, in a village of the Government of
+<span class='pageno' id='Page_iv'>iv</span>Kharkoff (Little Russia). He was educated at the Gymnasium
+and the University of Kharkoff, passing through the
+Faculty of Science. From 1864 to 1870 he worked at
+Zoology at Giessen, Göttingen and Munich, successively
+under three well-known zoologists, Leuckhart, Henle and
+Von Siebold, and was then appointed Professor of Zoology
+and Comparative Anatomy at Odessa. He made expeditions
+to Madeira, Teneriffe and the Kalmuck Steppes in
+connection with his zoological researches. In 1882, in consequence
+of administrative difficulties, arising as part of the
+troubles that followed the murder of the Tzar, Alexander
+II., he resigned the Professorship and became Director of
+the municipal Bacteriological Laboratory. In 1888 he went
+to the Pasteur Institute, and has remained there since that
+time.</p>
+
+<p class='c007'>The earlier part of Metchnikoff’s career was devoted to
+Zoology, and chiefly to investigation of the embryological
+history of the lower invertebrates, and the sequence of his
+discoveries should afford food for reflection to those Baconian
+economists who are unwilling to shelter any tree of knowledge
+that does not give immediate promise of marketable
+fruit. The labour of many years spent in minute tracing of
+the development of insects, echinoderms, worms and jellyfish,
+would appear sufficiently unprofitable to those who
+give a scanty support to Botany as the provider of drugs,
+who tolerate Chemistry because it has supplied aniline dyes,
+and who patronise the physical sciences from a lively sense
+of the convenience of telephones and telegraphs. And yet
+from these remote, inhuman interests, Metchnikoff, without
+intellectual transition, passed directly to results affecting
+vitally the human race, and became one of the high priests
+of Bacteriology and a guardian of the Pandora’s box of
+modern times.</p>
+
+<p class='c007'><span class='pageno' id='Page_v'>v</span>From observations made originally on water-fleas, he was
+led to discover the functions of the white corpuscles of
+human blood. He showed by what mechanism these made
+perpetual war against the intruding microbes of disease, and
+he laid the foundations of knowledge as to the agencies that
+weaken and the modes of strengthening these guardians of
+our health. In a series of investigations into the phenomena
+of inflammation in men and lower animals, he carried his
+observations into new fields, and explained the relations of
+the white corpuscles to the juices that attract and repel them
+(chemotaxis). It was he, for instance, who discovered that
+these corpuscles, under certain circumstances, migrate into
+the hairs and absorb and remove the pigment, so producing
+the blanching of old age. Although popularly the most interesting
+this was far from being the most important of the
+changes of senile decay that he found to be due to the
+activity of the wandering cells of the body. And, as will
+be seen in the present volume, the actions and interactions
+of the bacteria harboured in the body, the white corpuscles
+that are a natural part of the body, and the various juices
+or serums produced naturally or introduced by accident or
+design, are concerned in life itself and the decay of life.</p>
+
+<p class='c007'>Metchnikoff is an expert of experts in the science of life,
+and has gained the right to a hearing by forty years of patient
+devotion and brilliant research. In the volume that
+he has now given to the public, he has addressed himself to
+the gravest and the most serious problems of humanity, to
+life and sex and death and the fear of death. From the
+earliest days when man could spare time from the satisfaction
+of his immediate wants to reflect upon his nature and
+destiny, these problems and the invention of fantastic solutions
+or evasive anodynes have absorbed his attention. The
+folklore and philosophy, the religion and poetry of all races
+<span class='pageno' id='Page_vi'>vi</span>and of all stages of culture, from savage barbarism to decadent
+refinement, revolve round these obsessions of the
+mind, and, as Metchnikoff most plainly shows, no enduring
+comfort has yet been found. Now for the first time in the
+history of thought, the exact methods of science have been
+brought to the statement of the problems.</p>
+
+<p class='c007'>In revising this translation of Metchnikoff’s book for the
+English-speaking public I have had to content myself with
+seeing that the plain meaning of the French was transformed
+to plain English, and that references to French editions were
+changed, so far as was possible, to corresponding references
+to English editions. Some of the phrases that recur were
+difficult to express. “Human nature” for instance is not
+an exact equivalent of <em>la nature humaine</em>, for the latter
+phrase has a complete significance, and very definitely implies
+not only the mental qualities of man, but his bodily
+framework, with its inherited and acquired anatomical structure
+and physiological functions. The phrase “human constitution,”
+especially in the common medical sense, carries
+more of the meaning, and I have used it occasionally. The
+word “harmony” means harmony with the environment,
+and disharmony is want of harmony or imperfect adaptation
+to the existing environment. In the case of the human
+organism, which has passed through profound changes at a
+rate prodigious in the history of evolution, many parts of
+the constitution are no longer in gear with the existing
+environment, and it is in such disharmonies that Metchnikoff
+finds the source of the troubles that have perplexed

+<p class='c007'>In several parts of this volume, and particularly in the
+chapter dealing with disharmonies in the reproductive functions,
+there is much plain speaking on matters that modern
+civilisation attempts to conceal. I have not had the impertinence
+<span class='pageno' id='Page_vii'>vii</span>to suppress or to alter a line or a word of these
+pages. They are written in high seriousness on fundamental
+facts of the constitution of man; they relate to problems
+and difficulties that every age in the history of man has had
+to face, and that are dealt with in the plainest language in
+the books of all the religions. For the first time proper
+knowledge has been brought to the task, and it is to be remembered
+that this volume is an attempt to explain mysteries
+of the flesh and of the spirit of which all existing
+explanations have failed to satisfy humanity. The volume
+is avowedly no more than a preliminary statement, a rallying-point
+for the work of future generations. But it awakens
+a new hope for humanity now that the old are fallen dumb;
+as Metchnikoff himself says, “If it be true that man cannot
+live without faith, this volume, when the age of faith seemed
+gone by, has provided a new faith, that in the all-powerfulness
+of science.” In every country, the new Order of priests
+of science, in the vigils of the laboratory, is working for the
+future of humanity.</p>

+</div>
+
+<p class='c006'>In offering this book to you, reader, I feel that I must justify
+its publication. I admit freely that more could be said for
+a finished study in which hypotheses were replaced by
+exact fact. But to get together assured results in a field
+so little explored is a great task, calling for time and much
+labour.</p>
+
+<p class='c007'>I remembered the adage, “<em>Ars longa, vita brevis</em>,” and
+I decided to publish what is really a programme of work to
+be carried out as fully as circumstances may permit. At
+all events, I hope that such a programme may have its
+value for younger investigators, who wish a point of orientation
+for their labours.</p>
+
+<p class='c007'>My book is addressed to disciplined minds, and in especial
+to biologists. As I wrote it, I had not the general public
+in my mind, and so I did not hesitate to devote nearly the
+whole of a chapter to “disharmonies in the apparatus of
+reproduction.” I see in that apparatus the clearest proof of
+the essential disharmony in the organisation of man.</p>
+
+<p class='c007'>I have to thank those friends who were familiar with my
+views and whose advice and assistance have helped me to
+develop them.</p>
+
+<p class='c007'>In particular, I desire to thank my friends Dr. E. Roux,
+who was at the pains to make my French more French;
+and Dr. J. Goldschmidt and Dr. Mesnil, who have read and
+revised the proof-sheets.</p>

+<p class='c008'>Importance of the study of the nature of man—The nature
+of man as the foundation of morality—Greek worship of
+human nature—Matriopathy of ancient philosophers—Rationalism
+of the eighteenth and nineteenth centuries—Degradation
+of human nature by religious doctrines—Influence

+human nature—Mutilation of the human body by
+primitive races</p>
+
+<p class='c006'>Notwithstanding the real advance made by science,
+expressions of discontentment with it are familiar. Science,
+it is said, no doubt has ameliorated the material conditions
+of human life, but is powerless to solve those moral and
+philosophical questions that interest cultured people so
+deeply. In this region science has done no more than to
+destroy the foundations of religion. It has robbed mankind
+of the consolations of religion without being able to
+replace them with anything more exact or more enduring.</p>
+
+<p class='c007'>It cannot be disputed that a general uneasiness disturbs
+the world of to-day. Although his environment is most
+favourable to the fulfilment of many of his capacities, man
+finds himself without orientation when he has to determine
+the course of his life, or to explain to himself his true relation
+to such categories of humanity as family, nation,
+<span class='pageno' id='Page_4'>4</span>race and human race. This uneasiness reveals itself as
+discontentment, and it leads to pessimism or to mysticism.
+Most of the philosophical systems of the nineteenth century
+were steeped in melancholy, and led straight to a
+denial of the possibility of happiness and even to an advocacy
+of extinction. The frequency of suicide has increased
+greatly among all the civilised peoples. There is no need
+to tabulate proofs of a notorious fact.<a id='r1'></a><a href='#f1' class='c014'><sup>[1]</sup></a></p>
+
+<p class='c007'>A remedy for this malady of the age has been sought
+in the attempt to restore religious and mystical faith.
+On all sides have sprung up efforts to found new religions
+or to amend the old. Many defenders of science have
+gone the length of admitting its incapacity to solve the
+problem of the existence of man; they have held that that
+problem was insoluble for the human mind. Such a depressing
+conclusion has been formulated in spite of many attempts
+to reach a rational conception of the universe and of man.</p>
+
+<p class='c007'>It is no new thing to ask if there be nothing but faith
+to control human conduct and to lead mankind towards
+universal happiness. Men of science and philosophers,
+in many ages, have thought that human nature itself could
+provide all the materials for a rational morality.</p>
+
+<p class='c007'>In the ancient world and, above all, among the Greeks,
+human nature was held in high esteem. The Oriental
+races, predecessors of the Greeks in civilisation, generally
+represented their gods as fantastic or grotesque beings,
+composites of men and animals. The Greeks made gods
+<span class='pageno' id='Page_5'>5</span>in their own image, giving them all the most beautiful
+qualities of the human race. Such a conception was a
+dominant factor in ancient Greek life and civilisation.
+The adoration of Man embraced the human body, and led
+to the despising of every mode of tampering with the
+natural body. Thus, for instance, shaving<a id='r2'></a><a href='#f2' class='c014'><sup>[2]</sup></a> of the face
+was regarded as a humiliation, for a smooth chin gave an
+unnatural, womanish cast to the face of a man.</p>
+
+<p class='c007'>The adoration of human nature by the Greeks appeared
+in Greek plastic art, and was the cause of its excellence.
+The ideal of art was to copy, in the most faithful way,
+the most perfect example of the human body, and Greek
+artists made measurements of the body so accurately
+that modern science has confirmed their chief results.<a id='r3'></a><a href='#f3' class='c014'><sup>[3]</sup></a>
+As sculpture most completely realised the Greek ideal of
+the human body, it became almost a national art among
+the Greeks.</p>
+
+<p class='c007'>Greek philosophy had an equally high opinion of human
+nature, of the human body, and of representations of the
+human body. Just as Greek art aimed at the presentation
+of the body of man, so Greek philosophy proclaimed the
+nobility of all human qualities, and inculcated the doctrine
+of a harmonious development of all sides of human
+nature.<a id='r4'></a><a href='#f4' class='c014'><sup>[4]</sup></a> Such a doctrine was formulated by Plato, and
+became a fundamental principle of the Old Academy;
+the New Academy assumed it, and handed it on to the
+Sceptics. According to Xenocrates (fourth century), who
+<span class='pageno' id='Page_6'>6</span>belonged to the Old Academy, happiness consisted not
+only in the possession of human virtue, but in the accomplishment
+of all natural acts.<a id='r5'></a><a href='#f5' class='c014'><sup>[5]</sup></a></p>
+
+<p class='c007'>The principle of a worship of human nature is in itself
+rather vague, and it is not surprising that disputes and contradictions
+arose in relation to its application. Thus Plato
+excluded pleasure from his conception of the good, while
+Aristotle, Plato’s pupil, held a contrary opinion. For the
+latter pleasure was the natural motive of human action, and
+its attainment was associated as intimately with the perfect
+life as beauty and health were associated with the perfect
+human body.<a id='r6'></a><a href='#f6' class='c014'><sup>[6]</sup></a></p>
+
+<p class='c007'>Under the name <em>Matriopathy</em> there arose, in the ancient
+world, a doctrine the object of which was the study of
+the goal of natural morality. This doctrine was held by
+many philosophers, but these applied it to the details of
+actual life in very different fashions. Thus, for the Stoics,
+the <em>summum bonum</em> and happiness, the most lofty aim,
+could not be found except by conforming life to nature.
+Conduct was to be brought into harmony with the rational
+order of nature in such a fashion that every conscious and
+rational being would perform no actions that could not be
+deduced from the general law.<a id='r7'></a><a href='#f7' class='c014'><sup>[7]</sup></a> The same principle of
+a life in harmony with nature led the Epicureans to the
+conclusion that “pleasure is a natural good, that is to
+say, a condition conformable with nature, and so bringing
+with it intrinsic contentment.”<a id='r8'></a><a href='#f8' class='c014'><sup>[8]</sup></a> Setting out from the same
+fundamental principle, the theories of the Stoics and Epicureans
+led in opposite directions.</p>
+
+<p class='c007'><span class='pageno' id='Page_7'>7</span>The Roman philosophers adopted the principle of a life
+strictly natural. Seneca, for instance,<a id='r9'></a><a href='#f9' class='c014'><sup>[9]</sup></a> enunciated the
+maxim: “Take nature as your guide, for so reason bids you
+and advises you; to live happily is to live naturally.”</p>
+
+<p class='c007'>Without following through the centuries the development
+of the idea in detail, I may content myself with saying
+that resort has been made to it, wherever there was sought,
+outside the sanction of religion, a rational principle to guide
+human conduct. It recurs even among those convinced
+Christians who rebelled against the asceticism and hatred
+of human nature that became prevalent in the early centuries
+of the Christian era.</p>
+
+<p class='c007'>The Greek conception of a life in harmony with nature
+found its most complete development in the rationalism
+of the Renaissance, and of the centuries that followed it.
+Hutcheson,<a id='r10'></a><a href='#f10' class='c014'><sup>[10]</sup></a> a Scotch philosopher of the eighteenth century,
+insisted that right was with the thinkers of the
+naturalistic school, and that the realisation of their ideal
+was to be considered as the highest virtue. He thus placed
+himself directly against the Scotch clergy who asserted the
+greatest contempt for human nature. Buckle<a id='r11'></a><a href='#f11' class='c014'><sup>[11]</sup></a> proclaimed
+that it was a high honour for Hutcheson to have been the
+first Scotchman to raise his voice publicly against the
+degrading views of his time.</p>
+
+<p class='c007'>The French philosophers of the eighteenth century, who
+sought to replace the religious foundations of conduct by
+rational principles, again had recourse to human nature.
+Not long before the French Revolution there appeared a
+treatise in three volumes, written by Baron d’Holbach,
+and entitled, “Universal Morality, or the Duties of Man
+<span class='pageno' id='Page_8'>8</span>based on Nature.”<a id='r12'></a><a href='#f12' class='c014'><sup>[12]</sup></a> Frankly a materialist and atheist,
+that writer laid it down as an axiom that “to be universal,
+the moral law must be founded on the essential nature of
+man, that is to say, on the properties and qualities found
+constantly in the human being, and that distinguish him
+from other animals.” To be well assured, “morality
+presumes a science of human nature.”<a id='r13'></a><a href='#f13' class='c014'><sup>[13]</sup></a></p>
+
+<p class='c007'>The principle of ancient philosophy reappeared in the
+works of rationalists of the nineteenth century. Wilhelm
+von Humboldt declared that “the ultimate ideal of man,
+the ideal prescribed for him by the irrefutable and eternal
+laws of reason, consisted in a development as harmonious
+as possible of all his qualities in their entirety.” The
+modern historian, Lecky,<a id='r14'></a><a href='#f14' class='c014'><sup>[14]</sup></a> defines the aim of life as the
+full development of all that exists in the proportions determined
+by nature.</p>
+
+<p class='c007'>Philosophers and historians are not alone in the adoption
+of Greek rationalism. Many naturalists, and among these
+some very distinguished authors, have spoken in the same
+sense. It is easy to see the Greek principle in such phrases
+as those of Darwin<a id='r15'></a><a href='#f15' class='c014'><sup>[15]</sup></a> when he wrote: “The term general
+good may be defined as the means by which the greatest
+possible number of individuals can be reared in full vigour
+and health, with all their faculties perfect, under the conditions
+to which they are exposed.”</p>
+
+<p class='c007'>Georges Seidlitz,<a id='r16'></a><a href='#f16' class='c014'><sup>[16]</sup></a> an advocate of the great English
+naturalist, got still nearer to the conception of the ancients.
+<span class='pageno' id='Page_9'>9</span>According to him, the moral and rational life consisted in
+“the accomplishment of all the functions of the body, in
+due but full proportion.”</p>
+
+<p class='c007'>Herbert Spencer,<a id='r17'></a><a href='#f17' class='c014'><sup>[17]</sup></a> in analysing the aim of existence,
+came to the conclusion that morality should be adjusted
+so as to make life as full and complete as possible. As a
+criterion of physical perfection, the English philosopher
+would accept only the complete devotion of all the organs
+to the accomplishment of all their functions, while his
+criterion of moral perfection was contribution to the general
+good. These views are plainly, if not exactly, expressions
+of the Greek ideal.</p>
+
+<p class='c007'>While, then, rational philosophers in all the ages have
+sought the foundation of morality in human nature itself, and
+have held human nature to be good, or even perfect, many religious
+doctrines have displayed a very different view. Human
+nature was regarded as being composed of two hostile
+elements, a body and a soul. The soul alone was to be
+honoured, while the body was regarded as the vile source
+of evils. Such a view led to the flagellations and torturings
+of the body which form so strange and so widespread a
+phenomenon. The Hindu fakirs who swing themselves on
+hooks, the dervishes and Mussulman Assouans who beat
+in their skulls with clubs, the Russian Skoptsy who emasculate
+themselves, and many other instances make it plain that
+natural perfection is not taken as the basis for conduct.</p>
+
+<p class='c007'>Buddha<a id='r18'></a><a href='#f18' class='c014'><sup>[18]</sup></a> in the clearest way showed his belief that
+human nature was base. Coming out from the apartments
+of the women, there came to him a “vivid idea
+of the impurity of the body, a feeling of repulsion from it,
+<span class='pageno' id='Page_10'>10</span>and of blame of it; regarding his own body and seeing
+its wretchedness, he began to despise it, and to formulate
+conceptions of impurity and purity; <em>from the sole of the
+feet to the crown of the head, to the limit of the brain, he saw
+that the body was born in impurity, came from impurity, and
+always let itself be drawn to impurity</em>.” These reflections
+led him to the conclusion: “What wise man, having regarded
+his own body, will not see in it an enemy?”</p>
+
+<p class='c007'>Towards the end of the old world, the Greek theory
+of human nature yielded to a very different conception.
+The opposition between the opinions of the Stoics on
+morality, and their admiration of human nature, led Seneca,
+one of the last Roman Stoics and a celebrated contemporary
+of Jesus Christ, to break completely away from the ancient
+doctrine. Convinced of the moral weakness and imperfection
+of man, and of the persisting power of evil, Seneca
+declared that human nature contained a vicious and essentially
+evil element. This element was seated in the body,
+which he regarded as so essentially vile that it is to be
+despised. Our body was no more than the dwelling of the
+soul, its temporary home, a place in which it cannot be
+at rest. The body was a burden which the soul would be
+rid of, a prison-house from which it would escape. According
+to Seneca<a id='r19'></a><a href='#f19' class='c014'><sup>[19]</sup></a> the soul must wrestle with the body, for
+the body brings to it nothing but suffering, while the soul is
+essentially pure and spotless, and as much above the body
+as divinity is above matter.</p>
+
+<p class='c007'>A dualism still more pronounced was characteristic of
+the early Christian view of human nature, and led to the
+depreciation of the body as compared with the soul. In
+the fourth and fifth centuries of our era such a view was
+so dominant that a struggle against the material side of
+<span class='pageno' id='Page_11'>11</span>our nature became a rule of life. The most absolute asceticism
+spread throughout the Christian world.<a id='r20'></a><a href='#f20' class='c014'><sup>[20]</sup></a> A struggle
+against hunger, thirst, and desire for sleep, rejection of all
+pleasures that come from impressions of sight, of hearing,
+or of the palate, and, above all, abstention from sexual
+intercourse, became, in the opinion of believers, the true
+aim of human life. The conviction that human nature
+was essentially corrupt led to a declaration of war against
+it; all the pleasures were forbidden, even the most innocent
+of them being thought vicious. What could be more in
+contrast with the calm and joyous philosophy of the Greeks,
+for whom there did not exist the idea of a struggle against
+the supposed corruption and imperfection of man? The
+dualistic theory made such demands on its proselytes that
+these, absorbed in the salvation of their souls, sank from
+the physical point of view to the level of wild beasts. Hermits
+resorted to the lairs of animals, abandoned their clothing
+and went about naked with shaggy and disordered hair.
+In Mesopotamia and a part of Syria there arose a sect
+of eaters of grass; these were people who had no dwellings
+and who ate neither bread nor vegetables, but wandered
+on the hills and fed on the herbage. Cleanliness of the
+body was regarded as an indication of corruptness of the
+soul, and among the most highly venerated of the saints
+were those who took no care of the body. Athanasius
+relates with approval that when St. Antony, the father of
+monks, became old he never washed his feet.<a id='r21'></a><a href='#f21' class='c014'><sup>[21]</sup></a></p>
+
+<p class='c007'>Such doctrines soon brought about a most serious perversion
+of the innate instincts of the human race. The
+senses of family and of society became so weakened that
+fanatical Christians were more than indifferent to their
+<span class='pageno' id='Page_12'>12</span>kinsmen and countrymen. One saint was venerated because
+he was hard and cruel only to his relatives. It is told
+of the Abbot Siseuss that on a believer asking to be received
+into the convent, he inquired if the suppliant had any one
+akin to him. “I have only a son,” said the Christian.
+“Well, then,” said the abbot, “take your son and cast
+him into the river, for thus only may you become a monk.”
+The father set about to do the bidding of the abbot, and
+it was only at the last moment that the order was recalled.
+For admission into a Christian community it was necessary
+to renounce one’s country.<a id='r22'></a><a href='#f22' class='c014'><sup>[22]</sup></a></p>
+
+<p class='c007'>Such ideas have struck a deep and enduring root. In
+the opinion of the ministers of the Scotch Church of the
+seventeenth century, according to Buckle,<a id='r23'></a><a href='#f23' class='c014'><sup>[23]</sup></a> there was
+nothing so surprising as that the earth could contain itself
+in the presence of that horrid spectacle, man, and that it
+did not gape, as in former days, to swallow him in the
+midst of his wickedness. For certainly, in the created
+universe, there could be nothing so monstrous and so horrible
+as man.</p>
+
+<p class='c007'>It was to be expected that when such conceptions
+prevailed, celibacy and repudiation of the reproductive
+instinct should have been made obligatory on the clergy.
+The words, reported by St. Matthew (xix. 11, 12), that
+“there be eunuchs who have made themselves eunuchs
+for the kingdom of heaven’s sake” were interpreted by
+some as implying a voluntary renunciation of marriage,
+while others insisted on the literal meaning and in
+consequence mutilated themselves more or less completely.
+The breasts of women were removed to eradicate the
+maternal instincts. But it is only the sect of Skoptsy, by
+<span class='pageno' id='Page_13'>13</span>no means a small body in Russia, that applies the gospel
+command in this stringent fashion. The wish announced by
+St. Paul (Corinthians vii. 7), “I say therefore to the unmarried
+and widows, it is good for them if they abide even
+as I; but if they cannot contain, let them marry, for it is
+better to marry than to burn,” soon became a command,
+and since the fourth century the Catholic Church has advocated
+celibacy of the clergy, although it was not enforced
+until the eleventh century (under Gregory VII.). A low
+view of human nature has survived in the Catholic Church
+even to our own times. Pope Leo XIII., in his “Encyclical
+on Freemasons,” proclaimed it.<a id='r24'></a><a href='#f24' class='c014'><sup>[24]</sup></a> “Human nature,”
+he said, “was contaminated by the Fall, and as it is therefore
+much more prone to vice than to virtue, in order to
+attain virtue it is absolutely necessary to restrain the wild
+impulses of the soul, and to control the appetites by reason.”</p>
+
+<p class='c007'>Art has reflected the Christian conception of human
+nature. Sculpture, which played so great a part in the
+ancient world, and which was intimately associated with
+Greek ideals, began to decline rapidly in the Christian era.
+It lasted longer in the Roman Empire of the East, but in
+Italy it was almost completely forgotten by the eighth
+century. Painting survived, but not without undergoing
+an extraordinary degeneration. All the Italian works of
+art of the Carlovingian period, displayed the utmost indifference
+to natural form, and a loss of the sense of harmony
+and beauty. Later on, Italian art fell lower still. “No
+one dreamed any longer of studying nature or of observing
+the human body. An epoch in which the interference of
+supernatural forces was generally accepted, and in which
+<span class='pageno' id='Page_14'>14</span>the conception of the universe was founded on a contrast
+between the natural and the supernatural, could not admit
+in its art the rule of natural law or a natural order of
+events.”<a id='r25'></a><a href='#f25' class='c014'><sup>[25]</sup></a></p>
+
+<p class='c007'>The intimate connection between the depreciation of
+human nature due to Christian doctrine and the inferiority
+of the art of the middle ages cannot be denied. Taine<a id='r26'></a><a href='#f26' class='c014'><sup>[26]</sup></a>
+writes of the period as follows: “If one considers the
+stained-glass windows or the images in the cathedrals, or
+the rude paintings, it appears as if the human race had
+become degenerate and its blood had been impoverished;
+pale saints, distorted martyrs, virgins with flat chests, feet
+too long and bony hands, hermits withered and unsubstantial,
+Christs that look like crushed and bleeding earthworms,
+processions of figures that are wan, and stiffened,
+and sad, upon whom are stamped all the deformities of
+misery and all the shrinking timidity of the oppressed.”</p>
+
+<p class='c007'>The art of the middle ages fell lower and lower until the
+Renaissance, with its return to the Greek ideal, brought
+new vigour. The great masters of the Renaissance were in
+addition scientific men who had studied mathematics and
+who employed the technique of mensuration; such were
+Alberti, Leonardo da Vinci, Michel Angelo, and others.
+The return to the Greek ideals and to nature brought with
+it the taste for beauty.</p>
+
+<p class='c007'>When the ancient spirit was born again, its influence
+reached science and even religion, and the Reformation
+was a defence of human nature. The Lutheran doctrines
+resumed the principle of a “development as complete as
+<span class='pageno' id='Page_15'>15</span>possible, of all the natural powers” of man, and saw in that
+ideal a guide for humanity. Compulsory celibacy was
+abolished, and free play was given to all the tendencies in
+conformity with the laws of nature.<a id='r27'></a><a href='#f27' class='c014'><sup>[27]</sup></a></p>
+
+<p class='c007'>Besides those whose religion led them to despise the
+human body, there have been many savage races and
+tribes who have practised mutilations of the body. It
+would be a long list were I to set out all the modes in which
+the human body has been disfigured. Treatises on Ethnography
+and the volumes of travellers contain a multitude
+of details of this sort. The hair, the teeth and the lips have
+been subjected to treatment with the object of making
+them as unlike the natural condition as is possible. Many
+of the lower races discolour their teeth, or remove some of
+them, or file them to points. Others insert in the lips
+pieces of wood, of stone, or of bone. A whole chapter
+might be occupied with an account of the disfiguring
+devices of tattooers. The skull, the breasts, and the feet,
+have all been subjected to deforming treatment.</p>
+
+<p class='c007'>Although there is not enough evidence to set down these
+practices to the existence of definite and self-conscious
+religious or philosophic doctrine, it is at least certain that
+the people among whom they occur are far from revering
+human nature in the fashion of the Greeks, but rather
+attempt to distort it in accordance with their own taste.
+Discontent with the natural conditions of existence is, as
+we have seen, so widespread that there is good reason for
+an inquiry as to the existence of some general principle
+underlying this diversity of opinion regarding human
+nature. I have already shown that this question of human
+nature has for long interested mankind, and has shared
+<span class='pageno' id='Page_16'>16</span>largely in the formation of ideas of the good and the beautiful.
+It is not too soon to submit the problem to rational
+investigation, using those rigid methods of science which
+have been learned in our epoch. I shall try to give an
+exposition of human nature in its strength and in its weakness.
+But before passing to man, I shall survey the lower
+forms of life, hoping to fix some landmarks that will be
+useful in the study of the larger problem.</p>

+
+<p class='c006'>Long before man appeared on the earth animals and
+plants were distributed over it. Some of these were endowed
+with but vague senses, while others had well-developed
+instincts, and some even a certain degree of intelligence
+which they applied for their self-preservation and for the
+propagation of their own kind.</p>
+
+<p class='c007'>Many species, well adapted for the resistance of external
+influences, have survived from very early times to the
+present day. In the Carboniferous period birds and mammals
+did not yet exist, and the thick forests, with undergrowths
+of gigantic ferns, were inhabited by large numbers of articulated
+animals, amongst which were scorpions and insects.
+The scorpions of that time resemble in every way those
+that actually live at the present day in tropical countries;
+and amongst the insects of that early epoch were some very
+<span class='pageno' id='Page_18'>18</span>like the cockroaches of to-day. Certain tree-like ferns of
+the present time are also very similar to those of the coal
+period. Amongst the animals the bodies of which are protected
+by a shell, such as foraminifera and mollusca,
+certain species have survived even from an earlier time than
+the coal period.</p>
+
+<p class='c007'>In contrast with this extraordinary survival, there are
+instances of the complete disappearance of numbers of
+species of animals and plants. In early times, during the
+Tertiary epoch, the virgin forests of Europe were inhabited
+by a large number of monkeys, of which fossil remains are
+now found, especially in Greece. These formerly existed
+even in Europe, and some anthropoid apes (<em>Dryopithecus</em>)
+have left traces in the tertiary deposits of France.<a id='r28'></a><a href='#f28' class='c014'><sup>[28]</sup></a> These
+animals, notwithstanding that their organisation was superior
+to that of scorpions and cockroaches, have not been
+able to adapt themselves to the altered conditions of modern
+Europe. A similar fate has come upon some of the higher
+mammals, such as the mammoth and the mastodon.</p>
+
+<p class='c007'>These facts do not bear testimony to the prevalent idea
+that there exists in nature a law of universal progress tending
+to the production of organisms more and more perfect from
+the point of view of complexity of structure. It is incontestable
+that forms higher in the scale of life have developed
+only after the appearance of lower forms. But it does not
+follow that development always takes a progressive march.
+Man is one of the later species that have appeared upon
+the earth, but there are others of still more recent date.
+It is very probable that certain species of lice have appeared
+subsequent to man, particularly the clothes-louse (<em>Pediculus
+vestimenti</em>). Amongst the true parasites which live only
+in the human body are some that have acquired their
+<span class='pageno' id='Page_19'>19</span>specific characters after the appearance of man. Such are
+certain tape-worms and microbes, such as a species of <em>gonococcus</em>.
+It is therefore amongst parasites and not to man
+that we must look for the latest products of creation.</p>
+
+<p class='c007'>In nature, then, there is no blind tendency towards progress.
+Organisms almost innumerable are born every day
+with variable characters. Those amongst them which are
+adapted to existing circumstances survive and produce offspring
+like themselves, but many do not reach maturity, and,
+living only for a short time, die without leaving issue.</p>
+
+<p class='c007'>To give the reader a better idea of adaptations and
+of their importance to living creatures, it will, perhaps, be
+as well to devote some space to an account of examples of
+them. Amongst organisms that attract our attention by
+their pleasing aspect, there are not many that can rival
+flowering plants. Every one admires the great beauty of
+the blossom of orchids. There can be no doubt that these
+flowers have not been developed to satisfy the æsthetic
+tastes of man, for the simple reason that orchids existed for
+a long time before man’s appearance.</p>
+
+<p class='c007'>Among orchids there is one which, for more than half
+a century, has been cultivated by man in many tropical
+countries. This is the Vanilla, the fruit of which produces
+one of the sweetest of spices.</p>
+
+<p class='c007'>In former days the pods of only the wild vanilla, which
+is an undergrowth of the forests of Mexico and South
+America, were gathered. But the employment of vanilla
+to flavour chocolate has rendered its artificial culture
+lucrative; consequently the plant has been transported to
+several warm countries where it could be acclimatised. It
+has flourished and borne numerous blossoms, but it has
+never produced fruit from which alone the aroma is obtained.
+As the question of the sterility of the vanilla was of great
+<span class='pageno' id='Page_20'>20</span>practical interest to the cultivator, the matter was investigated,
+and it was found that the flower remained sterile
+because the female and male parts could not come in contact.
+The pistils and stamens of the flower are well developed, but
+between these sexual organs is a membrane which prevents
+fertilisation. After this discovery was made, the idea
+occurred that the pollen of the vanilla flower might be
+transferred artificially to the stigma of the pistil so as to
+bring about “artificial” fertilisation. A young black
+slave, Edmond Albius, a native of Réunion, discovered
+in 1841 a practical method by which the male and
+female elements of the vanilla could be put in contact;
+and from this discovery there came a great extension of
+the cultivation of the orchid in many countries. At a
+certain period a small bamboo point or the tooth of a comb
+is introduced into the vanilla flower, and in this way, in
+a short time, a quantity of flowers may be fertilised and
+so made capable of bearing mature pods.<a id='r29'></a><a href='#f29' class='c014'><sup>[29]</sup></a></p>
+
+<p class='c007'>In the original home of the vanilla the intervention of
+man is unnecessary. In Guiana and Mexico fertilisation
+of the flower is the work of small bees (of the genus <em>Melipona</em>).
+They frequent the vanilla flowers to extract nectar,
+the material of their honey. Small humming-birds also
+hover over the vanilla blossoms, and by introducing their
+bills into the sexual organs of the flowers bring about contact
+of the male and female elements.</p>
+
+<p class='c007'>Sterility of the vanilla in the countries to which it has
+been introduced, before the employment of artificial fecundation,
+is easily explained by the fact that in these countries
+there are no insects nor humming-birds capable of transporting
+the pollen.</p>
+
+<p class='c007'>But it is not only the vanilla that requires the co-operation
+<span class='pageno' id='Page_21'>21</span>of living beings to produce its fruits. It is the case
+with many other orchids. In the flowers of these the pollen
+is massed together and cannot be transported by the air.
+It needs the aid of insects, as had already been pointed out
+by Sprengell in the eighteenth century, and above all by
+Darwin, whose splendid investigations are the basis of the
+following passages.<a id='r30'></a><a href='#f30' class='c014'><sup>[30]</sup></a></p>
+
+<p class='c007'>Insects, belonging to different groups, such as bees,
+wasps, flies, certain beetles, and many butterflies and moths,
+visit orchids to sip the nectar produced by the plants and
+stored in definite parts of the flowers. In order that their
+proboscis may reach the stores of sweet juice, the insects
+inevitably touch first the upper parts of the flowers, where
+the anthers are present. The pollen grains are clustered
+in masses, known as pollinia, and these adhere to the body
+of the visiting insect by means of an adhesive fluid which
+is secreted by an organ of the flower known as the <em>rostellum</em>.
+In this way the pollinia adhere firmly, it may be to the
+proboscis of butterflies, or to the head or any other part of
+the body of insects. They can leave the flower and fly
+away without losing the adhering pollinia, and in this
+manner they serve as the agents for sexual contact
+and for fertilisation of the orchids. Ménière relates that
+a person who kept bees near the garden of the Faculté de
+Toulouse complained that they returned from the garden
+with their heads covered with tiny yellow bodies which he
+was unable to clean off from them. It was easy to recognise
+in these bodies the pollinia of orchids very firmly
+attached to the bees’ heads.<a id='r31'></a><a href='#f31' class='c014'><sup>[31]</sup></a></p>
+
+<p class='c007'><span class='pageno' id='Page_22'>22</span>When an insect, bearing these pollinia, introduces itself
+into another flower of the same species of orchid, it inevitably
+comes in contact with the female apparatus, more
+particularly with the viscous surface of the stigma. Some
+of the grains of pollen contained in the pollen-mass adhere
+to the stigma and are thus enabled to fertilise the ovule.
+This carriage of pollen from one flower to another brings
+about a crossing which is necessary for the production of
+good seed. On the other hand, the seed which is the result
+of self-fertilisation of a flower is inferior.</p>
+
+<p class='c007'>An examination of the structure and form of the flowers
+of many orchids show that they are adapted in a truly
+marvellous way to the visits of insects that convey pollen.
+In each part of these flowers one can discern some useful
+arrangement to secure cross-fertilisation.</p>
+
+<p class='c007'>For the proper transmission of pollen it is necessary that
+the pollinia should adhere very firmly to the body of the
+insects, and that the viscous substance which holds them
+together should have time to solidify. It is thus of great
+advantage to the plant if the insects remain for a considerable
+time on the flower. In several orchids the nectar is
+not easily accessible, and frequently the insect has to search
+for a long time before finding what it desires, and sometimes
+it even has to pierce a membranous covering before
+reaching the fluid. The operation takes a certain time,
+and this is long enough to allow the mucus by which the
+pollinia adhere to the insect to set firmly.</p>
+
+<p class='c007'>In the case of orchids the mucus of which sets instantaneously,
+there is no reason for the visit of the insect to
+be prolonged. In such cases the nectar is easy to extract,
+and the insect finds it without loss of time.</p>
+
+<p class='c007'>Darwin, after describing these facts, proceeds to say:<a id='r32'></a><a href='#f32' class='c014'><sup>[32]</sup></a></p>
+
+<p class='c007'><span class='pageno' id='Page_23'>23</span>“In these five species” (in which the viscid matter “is
+so adhesive that it serves to attach the pollinia firmly to
+the insects without getting hard”), “and in these alone, we
+find copious nectar ready stored for rapid suction in open
+nectaries. On the other hand, whenever the viscid matter
+gets hard by exposure for a short time to the air, it would
+manifestly be advantageous to the plant if insects were
+delayed in obtaining the nectar; and in all such species
+the nectar is lodged within intercellular spaces, so that
+it can be obtained only by the inner membrane being penetrated
+at several points, and this will require time. If
+this double relation is accidental, it is a fortunate accident
+for the plants; but I cannot believe it to be so, and it
+appears to me one of the most wonderful cases of adaptation
+which has ever been recorded.”</p>
+
+<p class='c007'>Some orchids secrete instead of nectar a clear liquid like
+water. This fluid is collected in a petal inserted at the
+lower part of the flower and shaped into a deep cup-shaped
+receptacle. It does not attract insects, but by wetting
+their wings compels them to leave the flower by a different
+exit which passes close to the reproductive organs (<em>i.e.</em>,
+the anther and the stigma). The soft linings of the cup
+are greedily devoured by certain insects, particularly by
+bees. Dr. Cruger, who observed this, has often seen bees
+fall into the cup whereupon their wings became so wet as
+to prevent their flying away, and they have been obliged
+to get out by the channel that carries off the waste from
+the reservoir. As the saturated bees creep along the narrow
+passage after their involuntary immersion, they come
+inevitably in contact with the stigma and the masses of
+pollen. The latter adhere to the bodies of the bees and
+can be conveyed to the sticky stigma of a neighbouring
+flower.</p>

+</div>
+
+<p class='c007'><span class='pageno' id='Page_25'>25</span>In other orchids (<em>Catasetum</em>, Fig. 1), the male elements
+are discharged by a spring-like arrangement on the body
+of insects. When certain parts of the flowers are touched,
+the pollinia are thrown off like arrows, which, in the place
+of the barbs, have viscid swellings. “The insect, disturbed
+by so sharp a blow, or after having eaten its fill, flies sooner
+or later away to a female plant and, whilst standing in the
+same position as before, the pollen-bearing end of the arrow
+is inserted into the stigmatic cavity, and a mass of pollen
+is left on its viscid surface.”<a id='r33'></a><a href='#f33' class='c014'><sup>[33]</sup></a></p>
+
+<p class='c007'>After giving detailed descriptions of the cross-fertilisation
+of flowers by such peculiar means, Darwin makes the
+following remark: “Who would have been bold enough
+to have surmised that the propagation of a species depended
+on so complex, so apparently artificial, and yet so admirable
+an arrangement?”<a id='r34'></a><a href='#f34' class='c014'><sup>[34]</sup></a></p>
+
+<p class='c007'>One orchid (<em>Herminium monorchis</em>, Fig. 2), which bears
+very small flowers, is remarkable for the way in which it
+is fertilised by insects. Only very small insects are able
+to penetrate the flowers. The space being very limited
+these minute insects can enter the flower only in a particular
+way, and at one of the corners. This causes the pollinia
+to become attached always to the same place, which is on
+the outer side of one of the two front legs. When the
+insect, the carrier of the pollinia, enters a second flower,
+it can scarcely fail to fertilise the stigma, which is on the
+corresponding side. Darwin said that it would be difficult
+to find a case in which there was so marvellously complete
+an adaptation to a very peculiar mode of fertilisation as
+the little flower of <em>Herminium</em>.</p>

+
+<p class='c007'>In addition to orchids, there are other flowers the
+organisation of which is adapted in a remarkable way to
+fertilisation by insects. But to find perfect harmony in
+the nature of living beings it is not necessary to confine
+<span class='pageno' id='Page_27'>27</span>our observations to flowers. The animal world furnishes us
+with numerous examples. To avoid going into the details
+of these, I shall content myself with a description of the
+most remarkable instances.</p>
+
+<p class='c007'>Every one has seen, flying near the ground, small, slender,
+and pretty wasps. From time to time these bury themselves
+in the earth or sand, and re-appear in a few minutes.
+These are the fossorial wasps, the interesting habits of which
+have been studied by Mr. J. H. Fabre, of Avignon. They
+are not gregarious, but lead solitary lives and differ in their
+habits from their congeners. Bees feed their larvæ with
+honey and pollen which they take to them during the whole
+period of their development. Wasps are carnivorous,
+predatory insects, and bring their spoils to their brood of
+soft and feeble larvæ which are unable to provide for
+themselves. Bees and most wasps look after the welfare
+of their young ones in the fashion of human parents in
+nurseries.</p>
+
+<p class='c007'>Fossorial wasps act differently; they never see their
+young. They lay their eggs in burrows, sunk in the soil
+and hermetically sealed. The larvæ are hatched underground
+and are never seen by the mother. Provision
+sufficient for their development, however, is made in
+advance. Before depositing eggs, the females sink the
+burrows, and fill them with the spoils of the chase, which
+consist sometimes of spiders and sometimes of crickets or
+other insects. Each species of fossorial wasps preys on
+a particular kind of insect or on its allies, for the purpose
+of provisioning the burrows. These wasps are most fastidious
+in the choice of their food, and behave like collectors
+whose interest is only in a single or a few species of small
+animals. Léon Dufour, the well-known entomologist, was
+much struck by the ability displayed by certain wasps
+<span class='pageno' id='Page_28'>28</span>(<em>Cerceris</em>, Fig. 3) in seeking out and capturing the pretty
+beetles of the genus <em>Buprestis</em>, which he had great difficulty
+in finding himself. In making a study of these
+beetles he collected the material from the burrows of
+<em>Cerceris</em>, and so avoided the laborious task of obtaining
+them in the natural state of freedom.
+The burrows were filled
+with motionless, but perfectly
+well preserved, <em>Buprestes</em>. Although
+dead Coleoptera dried up
+in a short time, those recovered
+from the burrows remained in a
+good state of preservation for
+weeks. Léon Dufour came to the

+
+<p class='c007'>J. H. Fabre pursued the study of the habits of fossorial
+wasps further. He ascertained that the captured insects
+were not dead, but only paralysed. The continuance of the
+function of certain organs demonstrated that the <em>Buprestes</em>,
+the weevils and other small creatures collected in the burrows
+of fossorial wasps, were alive. They could even perform
+some slight movements, but they were incapable of locomotion,
+and so could not escape. The mechanism of this
+paralysis, as far as could be ascertained by Fabre, is one
+of the most remarkable phenomena in nature. The fossorial
+wasps, guided by their instinct, immediately after
+having seized an insect or spider, bury their sting in the
+nervous centre which controls the movements of the legs.
+When animals with soft bodies, such as spiders and young
+crickets, are attacked, the operation does not present any
+difficulties. But Coleoptera in general, and the <em>Buprestes</em>
+<span class='pageno' id='Page_29'>29</span>and weevils in particular, are furnished with a very hard
+covering which cannot be perforated by the small and
+slender sting of a fossorial wasp. To gain their object the
+wasps probe exactly between the first and second pair of
+legs in the median line of the under surface of the thorax.
+The skin is thinner at this spot, and they introduce their
+sting into the ganglia from which arise the nerves of the
+legs. In the case with the <em>Buprestes</em> these ganglia are
+set close to one another, and a single prick suffices to affect
+the nervous centres of three pairs of legs. Once the sting
+has been inserted in this way the <em>Buprestis</em> becomes paralysed,
+but lives for many days. “The <em>Cerceris</em> which preys
+on Coleoptera,” writes Fabre,<a id='r35'></a><a href='#f35' class='c014'><sup>[35]</sup></a> “appears to have made its
+choice according to the dictates of an exact physiology and
+anatomy. It is impossible to see in its proceedings the
+results of happy chance; more than chance is required to
+explain adaptations so precise.”</p>
+
+<p class='c007'>After having filled the burrow with a sufficient quantity
+of insects or spiders, fossorial wasps lay their eggs and carefully
+close up the entrance. In due course the larva is
+hatched, and devours the food that it finds close at hand.
+If the gathered insects were not paralysed, they could
+easily escape from their prison; if they were dead,
+putrefaction or desiccation (according to circumstances)
+would render them unfit for the larvæ. It is therefore
+sheer necessity that is the factor in the development of
+this marvellous instinct that induces the fossorial wasps
+to attack the nervous centres of their prey. When one
+insect has been devoured, the larva proceeds to another,
+and so on, until it is fully grown, whereupon it envelops
+itself in a case that protects it during the winter and
+<span class='pageno' id='Page_30'>30</span>following spring. In summer it changes at first into a
+chrysalis, and later into a perfect insect. It frees itself from
+the cocoon, takes to flight, and enters upon life like that
+of its mother, which it has never seen.</p>
+
+<p class='c007'>Of the harmonious phenomena in nature it is indeed
+difficult to find other examples so perfect as those of the habits
+of these fossorial wasps, or of the mechanism for the fertilisation
+of orchids. These harmonies in nature are
+constantly met with in the world of living beings, and it
+is not astonishing that they have for a long time attracted
+the attention of many observers and philosophers. As it
+seemed impossible to attribute them to the organisms themselves,
+because of the low rank and lack of intelligence of
+these, it has seemed only natural to set them down as a
+manifestation of a superior force which organises and
+directs all natural phenomena. This argument, however,
+omits one side of the medal.</p>
+
+<p class='c007'>Any close investigation of organisation and life reveals
+that, beside many most perfect harmonies, there are facts
+which prove the existence of incomplete harmony or even
+absolute disharmony. The examination of the flowers of
+orchids would lead one to the belief that each part, even the
+smallest and apparently most insignificant, has its <em>rôle</em> in
+the mechanism for fertilisation and cross-fertilisation. In
+reality it is not so. There are in certain orchids organs
+which do not fulfil any function.</p>
+
+<p class='c007'>Even among the species of <em>Catasetum</em>, in which the pollinia
+are thrown with force on the bodies of insects, there are
+some female flowers in which the male organs are rudimentary
+and without utility. In these flowers, according to
+Darwin,<a id='r36'></a><a href='#f36' class='c014'><sup>[36]</sup></a> “the two membranous sacks containing the
+rudimentary pollen-masses never open, but they easily
+<span class='pageno' id='Page_31'>31</span>separate from each other and from the anther. The tissue
+of which they are formed is thick and pulpy. Like most
+rudimentary parts, the pollen-masses vary much in size
+and form; they are only about one-tenth of the bulk of
+those of the male.” There are then, without doubt, some
+structures that are of no service.</p>
+
+<p class='c007'>The existence of these rudimentary pollinia, incapable
+of being transported or of fertilising the female element, is
+easily explained by the supposition that formerly the
+flowers of the <em>Catasetum</em> were true hermaphrodites, but that
+in the course of time the male organs have become incompletely
+atrophied in certain flowers, in which, on the other
+hand, the female part has increased. The occurrence of
+an actual degeneration is shown by the existence of rudiments
+of the pollinia too insignificant to accomplish their
+normal functions.</p>
+
+<p class='c007'>Rudimentary and useless organs are widely distributed,
+and we find them in many places. Familiar instances are
+the atrophied eyes of animals that live in the dark, and
+the sometimes rudimentary sexual organs of many plants
+and animals.</p>
+
+<p class='c007'>Not only are orchids and other flowers adapted to fertilisation
+by means of insects, but many insects display
+special adaptations to their habit of visiting flowers. Butterflies,
+bees, and many other insects, possess mouth organs
+modified for the purpose of penetrating flowers to secure
+nectar or pollen. Other insects, again, are not so fortunate
+in this respect. Darwin<a id='r37'></a><a href='#f37' class='c014'><sup>[37]</sup></a> on one occasion “found an
+extremely minute Hymenopterous insect vainly struggling
+to escape, with its head cemented by the hardened viscid
+matter to the crest of the rostellum and to the tips of the
+pollinia (of an orchid, <em>Listera ovata</em>, Fig. 4). The insect
+<span class='pageno' id='Page_32'>32</span>was not so large as one of the pollinia, and after causing the
+explosion had not strength enough to remove
+them; it was punished for attempting
+a work beyond its strength, and
+perished miserably.”</p>
+

+<p><span class='sc'>Fig. 4.</span>—<em>Listera ovata</em> (after Barla, “Flora of Nice,” 1868).</p>
+</div>
+</div>
+
+<p class='c007'>Many insects, well adapted for the purpose,
+delight themselves by sucking the
+nectar of flowers. Many others would wish
+to do the same, but their want of adaptation
+baffles them. A small “lady-bird”
+loves the sweet juice of flowers; it tries
+often to suck the nectar of the dandelion,
+but without success. Hermann Müller<a id='r38'></a><a href='#f38' class='c014'><sup>[38]</sup></a>
+has described the behaviour of this insect
+in procuring the nectar of <em>Erodium cicutorium</em>.
+“The awkward way in which this
+beetle, unadapted to feed on the plants,
+endeavours to obtain the honey, is too
+ludicrous not to be mentioned. After taking
+up a position on the petal, it puts its
+mouth in the direction of one of the honeycups
+which are situated on both sides of
+the base of the petal. The petal soon
+breaks off, upon which the insect fixes
+itself on a neighbouring sepal or falls to
+the ground with the petal. In the first
+case it proceeds to creep over the flower
+and ends by detaching all the petals; in
+the other case, on recovering from the
+shock, it quickly ascends another stem of
+the same plant and begins again. I have
+seen the same lady-bird fall four times in
+<span class='pageno' id='Page_33'>33</span>succession with petals which it had detached without gaining
+wisdom.”</p>
+
+<p class='c007'>The instincts of insects, well developed for certain functions,
+often present aberrations more or less whimsical and
+remarkable. The caterpillars of some butterflies, before
+changing into chrysalids, envelop themselves in a wellwoven
+cocoon capable of protecting them from noxious
+influences. Protected by this covering, the caterpillar
+changes into a chrysalid, and later into a butterfly, which
+perforates the end of the cocoon in order to emerge. When
+any external agency destroys the cocoon, normal metamorphosis
+becomes impossible, and the larva dies before
+its maturity. Fabre<a id='r39'></a><a href='#f39' class='c014'><sup>[39]</sup></a> questioned whether the caterpillar
+during the time of the weaving of the cocoon was capable
+of repairing it if it was damaged. For this object he cut
+with a pair of scissors the end of a cocoon in the course
+of construction by the caterpillar of the beautiful peacock-butterfly.
+In spite of the hole thus produced, the caterpillar
+continued its ordinary work without suspicion that
+it would be of no avail. On this occasion “the caterpillar
+of the peacock-butterfly, notwithstanding the certain fate
+of the future butterfly, continued peaceably to spin, without
+in the least modifying the regular progress of its labour;
+when the time had arrived for the putting in of the last
+defensive stitches it placed them in the perilous breach,
+but neglected to mend the destroyed part of the barricade.
+It performed its vain task, ignoring what was indispensable
+for success.”</p>
+
+<p class='c007'>Even amongst fossorial wasps, the instincts of which are
+so admirably developed, harmony is far from perfect. Fabre
+endeavoured to ascertain what effect was produced on these
+insects by taking away the egg laid in the burrow. He
+<span class='pageno' id='Page_34'>34</span>chose for this experiment the fossorial wasp <em>Pelopæus</em>
+(Fig. 5), which preys on spiders. He took away the egg which
+had been deposited in a carefully-prepared burrow, and
+watched the subsequent manœuvres. “The <em>Pelopæus</em> continued
+to store up spiders for the
+stolen egg; it gathered provisions
+that were not to be eaten; it
+redoubled its efforts to replenish
+a larder that I was constantly
+robbing with my forceps.” The
+insect neither discontinued its
+fruitless task nor appeared to be
+aware of its fruitlessness. Here,
+then, is an example of a foiled
+maternal instinct that gained no
+useful end.</p>

+</div>
+</div>
+
+<p class='c007'>In connection with such a slaughter for the benefit of a
+progeny that will never exist, I may mention observations
+relating to a quite different order of phenomena. There
+are many creatures that kill and devour their progeny. Not
+infrequently rabbits kill and devour all their progeny, or
+leave them to die without food or care. Sometimes
+the culprits are young rabbits without experience; but
+this aberration of instinct is also met with in old rabbits,
+which once and for all have contracted the habit of abandoning
+or eating their young. Some females of other species
+of mammals and of birds have often been surprised in the
+act of deserting or of killing their offspring.</p>
+
+<p class='c007'>Perversion of sexual instinct is frequent enough amongst
+animals. Huber<a id='r40'></a><a href='#f40' class='c014'><sup>[40]</sup></a> states that when male ants have a lack
+of females they ravish the workers, the attacks being fatal,
+<span class='pageno' id='Page_35'>35</span>as the sexual organs are incompletely developed and
+functionally incapable. Abnormal pairing has also been
+observed in the stag-beetle of the genus <em>Lucanus</em>, in bees,
+and, above all, in cockchafers.<a id='r41'></a><a href='#f41' class='c014'><sup>[41]</sup></a> Higher animals, such as
+dogs, furnish analogous examples of sexual perversion.</p>
+
+<p class='c007'>Onanism is well known amongst mammals. It is frequent
+among monkeys in menageries, and also in rutting
+stags, the latter discharging the seminal fluid by friction
+with trees. Stallions and mares have often been observed
+in the act of satisfying their sexual appetites by abnormal
+means. There are several other species (dogs, bears, chamois,
+elephants, parrakeets, etc.,) which resort to onanism.<a id='r42'></a><a href='#f42' class='c014'><sup>[42]</sup></a></p>
+
+<p class='c007'>These disharmonious instincts do not in the least cause
+the death of the animals that manifest them. But there
+exist in nature instinctive aberrations much more dangerous.
+Who has not seen in the summer numerous insects gathered
+round lamps and candles, attracted by the light? Among
+these are Coleoptera, Neuroptera (<em>Phryganea</em>), Ephemera, and,
+most frequently of all, small nocturnal Lepidoptera. After
+flying round and round the light several times, they singe
+their wings and die in numbers. This instinct is so constant
+and so developed amongst many of these insects, that
+it has been used against them for their own destruction.
+Thus amongst the means advocated for destroying a moth,
+<em>Botys sticticalis</em>, the caterpillars of which devour cereals and
+beetroot,<a id='r43'></a><a href='#f43' class='c014'><sup>[43]</sup></a> is the lighting of numerous fires in the fields.
+The moths, attracted by the light, fall in the flames and
+die in quantities.</p>
+
+<p class='c007'>When the usual swarms of may-flies emerge from the
+water, fishers make straw fires on their boats, and the
+<span class='pageno' id='Page_36'>36</span>insects singe their wings. The innumerable bodies incapable
+of flight fall into the water, and provide a coveted
+food for the fish.<a id='r44'></a><a href='#f44' class='c014'><sup>[44]</sup></a> This disharmonious and fatal instinct is
+displayed chiefly by nocturnal insects that rest during the
+day and do not leave their retreats till after sunset. In
+the cornfields Coleoptera of the genera <em>Anisoplia</em> and <em>Rhizotrogus</em>,
+resembling each other in form and general appearance,
+are to be found. When a fire is lighted in the darkness
+of the night it is only the <em>Rhizotrogus</em> that approaches it
+at the risk of its life. The <em>Anisoplia</em> remains quiet in the
+midst of the corn. The latter kind of beetle pairs during
+the day, while the <em>Rhizotrogi</em> satisfy their sexual desires
+during the night. Moreover, it is the males only of this
+species that fly about in the darkness and approach the
+fire, whilst the females rest at home in the plants.<a id='r45'></a><a href='#f45' class='c014'><sup>[45]</sup></a> It is
+probable, therefore, that light induces a sort of sexual excitement
+in these male beetles. The males, searching for the
+female, believe her to be in the midst of the flames, towards
+which they fly without being conscious of the danger they
+incur.</p>
+
+<p class='c007'>Such an interpretation of this disharmonious and suicidal
+instinct is confirmed by the fact that the moths attracted
+by fire are also almost exclusively males. Moreover, entomologists
+have advised against the lighting of fires by agriculturists
+in the belief that they destroy the noxious <em>Botys</em>,
+as they maintain that the females are not attracted. These
+latter therefore live on, and, being capable of laying eggs,
+produce a generation of voracious caterpillars.</p>
+
+<p class='c007'>Of the <em>Ephemera</em> attracted by fire in such great quantities
+males are by far the more numerous. It is therefore really
+very probable that the mad excitement which leads to the
+<span class='pageno' id='Page_37'>37</span>destruction of so many male insects, represents a sort of
+sexual aberration. In this connection it is to be remembered
+that, amongst Coleoptera, species exist of which the
+females, hidden in the grass, produce intense light which
+attracts the males. In the common glow-worm, the female,
+which is devoid of wings, alone shines with the familiar
+greenish glitter. Even in species of which the two sexes
+are luminous, the female shines more vividly. It is true
+that there are some beetles with luminous larvæ, a fact that
+led Darwin<a id='r46'></a><a href='#f46' class='c014'><sup>[46]</sup></a> to remark that the production of light by
+insects may serve to frighten enemies. This is possible,
+and it is also possible that certain insects make use
+of their luminosity to light their way in the darkness.<a id='r47'></a><a href='#f47' class='c014'><sup>[47]</sup></a>
+But, notwithstanding this, the sexual character of the
+luminous organ is so manifest in certain species that it is
+impossible to doubt its function as a means of attracting
+the male.</p>
+
+<p class='c007'>In conclusion I may say that it is not my purpose at
+present to discuss the meaning of an instinct so fatal to
+insect life. I wish only to point out the frequency of the
+natural occurrence of disharmony, so that the satisfaction
+of an instinct is fatal to so many of its possessors.</p>
+
+<p class='c007'>It is plain that an instinct, or any other form of disharmony
+leading to destruction, cannot increase, or even endure
+very long. The perversion of the maternal instinct tending
+to abandonment of the young is destructive to the stock.
+In consequence, individuals affected by it do not have the
+opportunity of transmitting the perversion. If all rabbits,
+or a majority of them, left their young to die through
+neglect, it is evident that the species would soon die out.
+<span class='pageno' id='Page_38'>38</span>On the contrary, mothers, guided by their instinct to nourish
+and foster their offspring, will produce a vigorous generation
+capable of transmitting the healthy maternal instinct so
+essential for the preservation of the species. For such a
+reason harmonious characters are more abundant in nature
+than injurious peculiarities. The latter, because they are
+injurious to the individual and to the species, cannot perpetuate
+themselves indefinitely.</p>
+
+<p class='c007'>In this way there comes about a constant selection of
+characters. The useful qualities are handed down and
+preserved, while noxious characters perish and so disappear.
+Although disharmonies tend to the destruction of a species,
+they may themselves disappear without having destroyed
+the race in which they occur.</p>
+
+<p class='c007'>This continuous process of natural selection, which offers
+so good an explanation of the transmutation and origin of
+species by means of preservation of useful and destruction
+of harmful characters, was discovered by Darwin and
+Wallace, and was established by the splendid researches
+of the former of these.</p>
+
+<p class='c007'>Long before the appearance of man on the face of the
+earth, there were some happy beings well adapted to their
+environment, and some unhappy creatures that followed
+disharmonious instincts so as to imperil or to destroy their
+lives. Were such creatures capable of reflection and communication,
+plainly the fortunate among them, such as
+orchids and fossorial wasps, would be on the side of the
+optimists; they would declare this the best of all possible
+worlds, and insist that, to secure happiness it is necessary
+only to follow natural instincts. On the other hand, the
+disharmonious creatures, those ill adapted to the conditions
+of life, would be pessimistic philosophers. Consider the case
+of the lady-bird, driven by hunger and with a preference
+<span class='pageno' id='Page_39'>39</span>for honey, which searches for it on flowers and meets
+only with failure, or of insects driven by their instincts into
+the flames, only to lose their wings and their lives; such
+creatures, plainly, would express as their idea of the world
+that it was fashioned abominably, and that existence was
+a mistake.</p>
+
+<p class='c007'>As for man, the creature most interesting to us, in what
+category does he fall? Is he a being whose nature is in
+harmony with the conditions in which he has to live, or is
+he out of harmony with his environment? A critical
+examination is needed to answer these questions, and to
+such an examination the pages to follow are devoted.</p>

+
+<p class='c006'>To understand human nature it is necessary first to give
+an account of the origin of man. This question has preoccupied
+mankind for ages, and for a long time it was
+believed that a solution of the problem was to be found in
+religious dogmas. Man was regarded as being of supernatural
+origin, the result of a special creation. Scientific
+criticism has now shown that there are no grounds for such
+a conclusion.</p>
+
+<p class='c007'>Nearly half a century ago Darwin applied to man his
+discovery of the principle of natural selection, and of the
+part played by that in the origin and transmutation of
+species. Soon after the publication of the “Origin of
+Species,” attention was given to the special case of man.
+<span class='pageno' id='Page_41'>41</span>In 1863 Huxley<a id='r48'></a><a href='#f48' class='c014'><sup>[48]</sup></a> gave an admirable review of the problem
+in his work on “Man’s Place in Nature.” He brought
+forward arguments of the highest scientific validity in
+support of the thesis that man is descended from animals,
+and that he is a mammal most nearly related to monkeys,
+and among these to the anthropoid apes. In spite of this
+masterly exposition, there are still persons of high intelligence
+and superior education who declare that science has
+not yet answered the question as to whence he came, and
+that the theory of evolution will never provide an answer.<a id='r49'></a><a href='#f49' class='c014'><sup>[49]</sup></a>
+Close examination of the structure of man has proved, in
+the most definite fashion, the existence of a near kinship
+with the higher monkeys, or anthropoids. When the chimpanzee
+and the ourang-outang were discovered, comparison
+became inevitable, and many naturalists, including the great
+Linnæus, saw that the human race must find its place in
+classification near the anthropoids.</p>
+
+<p class='c007'>Now that all the details of the human organisation have
+been studied, and the anatomical structures of man and
+large monkeys without tails have been compared, bone
+with bone and muscle with muscle, a truly astonishing
+analogy between these organisms is made manifest, an analogy
+apparent in every detail. It is known that in the natural
+history of mammals the teeth play an important part as
+a means of determining differences and relationships. The
+dentition of man bears a very great resemblance to that
+of anthropoids. Every one knows the <em>milk teeth</em> and the
+<em>permanent teeth</em> of man. The anthropoid apes bear in this
+respect an astonishing likeness to man. The number
+(thirty-two in the adult), the form and general arrangement
+<span class='pageno' id='Page_42'>42</span>of the crown, are identical in man and anthropoid apes.
+The differences are to be found only in minor details, such
+as the exact shape and relative dimensions and the number
+of cusps. It can be said in a general way that in the anthropoid
+apes the teeth are more strongly developed than in
+man. The canines are much longer and the roots of the
+pre-molars are more complex in the gorilla than in man.</p>
+
+<p class='c007'>But the fact must not be lost sight of, that all these differences
+are less pronounced than those which exist between
+the dentition of anthropoid apes and that of all other
+monkeys. Even in the cynocephalous monkeys, those that
+most nearly approach the anthropoids, the teeth exhibit
+marked differences. Thus, the forms of the upper molars
+are quite different in the baboon and in the gorilla. The
+canines are longer, and the pre-molars and molars are still
+more complex in the baboon.</p>
+
+<p class='c007'>In the monkeys of the New World, the dentition differs
+still more from that of man and anthropoids. Instead of
+thirty-two teeth, they possess thirty-six in the adult condition.
+The number of pre-molars is twelve instead of
+eight. The general form and the crowns of the molars are
+very different from those of anthropoid apes.</p>
+
+<p class='c007'>These considerations led Huxley to conclude that “it
+is obvious that, greatly as the dentition of the highest ape
+differs from that of man, it differs far more widely from that
+of the lower and lowest apes.”<a id='r50'></a><a href='#f50' class='c014'><sup>[50]</sup></a></p>
+
+<p class='c007'>Another character which shows that anthropoids are
+nearer man than other monkeys is furnished by the anatomy
+of the sacrum. In monkeys as a whole the sacrum
+is composed of three, or rarely four, vertebræ, while in
+anthropoid apes it contains five, that is to say just as many
+as in man.</p>
+
+<p class='c007'><span class='pageno' id='Page_43'>43</span>The whole skeleton, and particularly the skull of man, and
+the higher monkeys, present certainly some marked differences;
+but here again the differences are less than those
+between the anthropoid apes and other monkeys. As
+regards the osteology the proposition laid down by Huxley
+is just. “So that, for the skull, no less than for the skeleton
+in general, the proposition holds good, that the differences
+between man and the gorilla are of smaller value than those
+between the gorilla and some other apes.”<a id='r51'></a><a href='#f51' class='c014'><sup>[51]</sup></a></p>
+
+<p class='c007'>The believers in the doctrine that the human species is
+essentially distinct from all the known monkeys have laid
+great stress on the difference between the foot of man and
+that of anthropoid apes. This difference cannot be denied.
+Man assumes the direct posture habitually, while monkeys,
+even the highest of them, walk on two legs only occasionally.
+There has followed from this a greater development
+of the feet in monkeys. Yet this difference ought not to
+be exaggerated. It has been sought to prove that monkeys
+are “quadrumanous,” and that their hind legs terminate
+in “hind-hands.” But it is clearly shown that in all essential
+respects the hinder limb of the gorilla terminates in as
+true a foot as that of man.<a id='r52'></a><a href='#f52' class='c014'><sup>[52]</sup></a> “The hind limb of the gorilla,
+therefore, ends in a true foot, with a very movable great
+toe. It is a prehensile foot, indeed, but is in no sense a
+hand; it is a foot which differs from that of man not in
+any fundamental character, but in mere proportions, in
+the degree of mobility, and in the secondary arrangement
+of its parts.”<a id='r53'></a><a href='#f53' class='c014'><sup>[53]</sup></a></p>
+
+<p class='c007'>In all these cases the argument is confirmed, “that be
+the differences between the hand and foot of man and those
+of the gorilla what they may, the differences between
+<span class='pageno' id='Page_44'>44</span>those of the gorilla and those of the lower apes are much
+greater.”<a id='r54'></a><a href='#f54' class='c014'><sup>[54]</sup></a></p>
+
+<p class='c007'>The comparison of muscles and of other internal organs
+leads to the same conclusion; the differences between
+monkeys are more varied and greater than those between
+anthropoids and man. The
+anatomy of the brain has
+been much discussed with
+regard to this. Several
+distinguished zoologists,
+amongst them Owen in
+particular, have insisted
+on the absence in all
+monkeys of certain parts
+of the brain peculiarly
+characteristic of man.
+Such are the posterior
+lobe, the posterior cornu,
+and the lesser hippocampus. Controversy on this topic has
+been animated; but, ultimately, the opinion of Owen did
+not triumph, and now it is unanimously accepted that the
+parts of the brain in question are “precisely those structures
+which are the most marked cerebral characters common to
+man with the apes. They are among the most distinctly
+simian peculiarities which the human organism
+exhibits.”<a id='r55'></a><a href='#f55' class='c014'><sup>[55]</sup></a></p>

+
+<p class='c007'>It is not surprising,
+in the face of
+resemblances so
+numerous, that forty years’ science has proclaimed the existence
+of a close affinity between man and the anthropoid apes.
+The view has become an established doctrine, now that
+no single fact has been brought against it. Since the
+theory was enunciated we have learned much regarding
+the natural history of these apes. Generally, when a theory
+is false, a new set of facts overthrows it. Attempts may be
+made to trim the new facts to the existing theory, but such
+attempts are doomed to failure, and the theory disappears. It
+is of special interest, then, to confront the simian theory of
+the origin of man with a series of facts gathered by science
+since the theory was propounded.</p>
+
+<p class='c007'>When Huxley wrote, the embryological history of anthropoid
+apes was practically unknown. Darwin, Vogt, and
+Haeckel, in their attempts to support the theory of the
+animal origin of man, had not sufficient knowledge of the
+<span class='pageno' id='Page_46'>46</span>embryology of monkeys. It is only recently that important
+work on this subject has been published.</p>
+
+<p class='c007'>It is known that the history of development is very often
+an excellent guide in tracing the relationship of organisms.
+It is therefore interesting to examine the established facts
+concerning the embryology of anthropoid apes. The
+material for these studies is very difficult to obtain, and
+it is not astonishing that even our present state of knowledge
+is still imperfect.</p>

+<p><span class='sc'>Fig. 9.</span>—Human fœtus of three months and a half.</p>
+</div>
+</div>
+
+<p class='c007'>With regard to the embryos themselves, the similarity
+between those of monkeys and of man is very great. Selenka
+insists on the fact that the youngest stages of human development
+that have been obtained can hardly be distinguished
+from those of the lower monkeys either in position
+or in shape. More advanced stages exhibit greater differentiation,
+and the later embryos of man resemble those of
+<span class='pageno' id='Page_48'>48</span>anthropoids much more closely than those of the lower
+monkeys. The fœtus of the gibbon, figured by Selenka
+(Fig. 8), presents the most striking likeness to a corresponding
+human fœtus (Fig. 9).</p>
+
+<p class='c007'>Later on, the characters that distinguish man from even
+the highest of the apes become more and more pronounced.
+In the anthropoids the facial portion becomes more and more
+prominent, and betrays a bestiality absent from the human
+form. None the less the resemblance between the nearly
+mature fœtus of anthropoids and human embryos of about
+the sixth month is evident enough. M. Deniker had the
+good fortune to obtain the late fœtus of a gorilla—a very rare
+piece of fortune—and he has made an elaborate investigation
+of its structure. The general appearance (Fig. 10) is
+quite enough to show the close relationship with a human
+fœtus of a corresponding age (Fig. 11). It is plain, moreover,
+that the young gorilla is more human-like than is the adult.
+Detailed anatomical investigation only confirms this conclusion.</p>
+
+<p class='c007'>The skulls of the young stages of anthropoids are much
+more human in their character than the adult skulls. Selenka
+states that such young skulls of different anthropoids not
+only resemble one another more closely, but are more
+human. As soon as the teeth begin to appear, the individual
+characters are assumed so rapidly, and become so
+marked, that, in the absence of the intermediate stages,
+it would be difficult to establish the kinships.</p>
+
+<p class='c007'>The data derived from embryology do not point to any
+one of the existing genera of monkeys as the ancestor of
+man. They lead us to infer, rather, that man and the
+anthropoid apes had a common origin, and palæontological
+evidence must be scanned to find this ancestor. The greatest
+importance has been attached to a discovery in Java, made
+<span class='pageno' id='Page_49'>49</span>in 1894 by Eugène Dubois. The remains, consisting of the
+crown of a skull, two teeth and a femur, belonging to a
+creature for which the name <em>Pithecanthropus erectus</em><a id='r58'></a><a href='#f58' class='c014'><sup>[58]</sup></a> has
+been invented, have been interpreted by several anatomists
+as those of a form intermediate between man and the
+anthropoid apes. However, as the facts about this creature
+are meagre and have been interpreted differently, I shall
+not make use of them in my argument. Even apart from
+them, the simian origin of man may be taken as proved.</p>
+
+<p class='c007'>The series of facts that I have been employing as evidence
+of the relationship between men and anthropoid apes has
+been drawn from the observations of anatomists and embryologists.
+Darwin, seeking to broaden the basis of the argument,
+called attention to the resemblances of the parasites
+of men and apes, as evidence of a close similarity of physiological
+processes in the creatures. In the last few years,
+investigations in a very different field seem capable of
+throwing a novel light on the question.</p>
+
+<p class='c007'>When the blood of one mammal is injected into the body
+of another, the latter shows remarkable modifications.
+When there is added to a serum, prepared from the blood
+of a rabbit and consisting of a colourless transparent liquid,
+a few drops of blood drawn from another rodent (for instance
+a guinea-pig), nothing unusual happens. The blood of the
+guinea-pig preserves its normal colour, and its corpuscles
+remain practically unaltered. If, instead of adding guinea-pig’s
+blood to the serum of rabbit’s blood, we add a serum
+drawn from the blood of the guinea-pig, still no special
+change occurs.</p>

+
+<p class='c007'>If, however, a serum be prepared from the blood of a

+of a guinea-pig, the serum shows new and striking qualities.
+The addition to it of some drops of guinea-pig’s blood
+brings about, in a very short time, a changed appearance.
+The red liquid, at first opaque, becomes transparent. The
+<span class='pageno' id='Page_51'>51</span>mixture of the prepared serum of the rabbit with the blood
+of the guinea-pig will assume the colour of claret mixed
+with water. The change is due to solution of the red

+</div>
+
+<p class='c007'><span class='pageno' id='Page_52'>52</span>This serum has still another property not less worthy of
+attention. If there is added to it not pure blood but only
+blood serum of the guinea-pig, a disturbance in the mixture
+occurs almost at once, and leads to the forming of a precipitate
+more or less abundant.</p>
+
+<p class='c007'>The injection of the blood of the guinea-pig into a rabbit
+has therefore changed the serum of the latter by introducing
+new properties: that of dissolving the red corpuscles
+of the guinea-pig and of giving a precipitate with the blood
+serum of the same animal.</p>
+
+<p class='c007'>Frequently the blood serum of animals prepared by previous
+injections of the blood of other species of animals is
+strictly specific. In such cases the serum only gives a
+precipitate with the serum of the species which has furnished
+the blood for the injections, and only dissolves the red
+corpuscles of this same species. But there are some instances
+in which a serum of a prepared animal dissolves, not only
+the red corpuscles of the species which has furnished the
+injected blood, but those of allied species. Thus the blood
+serum of the rabbit, after some injections of blood of the
+chicken, becomes capable of dissolving not only the red
+corpuscles of the chicken but also those of the pigeon,
+although in a less degree.</p>
+
+<p class='c007'>It has been suggested that assistance could be rendered
+to forensic medicine by making use of this property
+of serums, to discover the origin of a certain blood. As
+is well known, it is often very important to decide whether
+a stain was caused by the blood of man or of another animal.
+Until quite recently it was not known how to distinguish
+human blood from that of other mammals. Experiments
+have been made to discover if the red corpuscles found in
+the blood stain could be dissolved by the serum of animals
+which had previously been injected with the blood of man.
+<span class='pageno' id='Page_53'>53</span>In a certain case the human origin of the stain in question
+was shown. But it was soon discovered that this method
+was not infallible. It is now found that the method of
+precipitates gives much more conclusive results. It is done
+in this way: Human blood is injected several times into
+any animal (rabbit, dog, sheep, horse). Some time afterwards
+the animal is bled, and a clear and limpid serum,
+quite devoid of corpuscles, is prepared. When there is
+added to this serum one or several drops of human serum,
+it forms immediately a precipitate which falls to the bottom.
+In this way it is discovered whether the prepared serum
+is sufficiently active. It then becomes possible to recognise
+even dried human blood. A little of such blood is dissolved
+in normal salt solution, and placed in a tube containing
+the serum of an animal prepared by means of the injections
+of human blood. If a precipitate forms in the liquid in a
+short time, the fact indicates that the stain is really human
+blood. This method is being practised in forensic medicine.</p>
+
+<p class='c007'>This reaction is of great interest to us because it is of
+assistance in revealing the relationship between species.
+The serum of an animal prepared with the blood of the
+fowl gives a precipitate, not only with the serum of the
+fowl itself, but also with that of the pigeon; on the other
+hand, it remains undisturbed when the serum of mammals
+is added. The reaction indicates then that there is a sufficiently
+marked degree of relationship between the fowl and
+the pigeon. Here is another example: the serum of an
+animal prepared with the blood of an ox gives an abundant
+precipitate when there is added to it a little blood serum
+of the ox, but it does not produce this reaction with the
+serum of any of the other mammals, not even with that
+of the sheep, stag and deer.<a id='r59'></a><a href='#f59' class='c014'><sup>[59]</sup></a> The relationship between
+<span class='pageno' id='Page_54'>54</span>the <em>Bovidæ</em> and these other ruminants is then not so close
+as that between the fowl and the pigeon.</p>
+
+<p class='c007'>How does the serum of animals which has been injected
+with human blood behave? The serum capable of giving a
+precipitate with human serum does not produce the same
+reaction except with the serum of some monkeys (the small
+<em>Papio</em>).<a id='r60'></a><a href='#f60' class='c014'><sup>[60]</sup></a></p>
+
+<p class='c007'>Gruenbaum, of Liverpool,<a id='r61'></a><a href='#f61' class='c014'><sup>[61]</sup></a> has been fortunate enough to
+procure a considerable quantity of the blood of three large
+anthropoid apes—the gorilla, chimpanzee, and ourang-outang.
+He has been able to prove that the serum of
+animals injected with man’s blood gives a precipitate not
+only with this blood but also with that of the above-mentioned
+apes. It was impossible for him “to distinguish this
+precipitate as regards quality and quantity from that
+which is obtained with human blood.”</p>
+
+<p class='c007'>To verify this result, Gruenbaum prepared the serum of
+animals injected with the blood of the gorilla, chimpanzee,
+and ourang-outang. These three kinds of serum gave precipitates
+with the blood of these three apes, and to the same
+extent with the blood of man. It is therefore evident that
+there exists between the human species and the anthropoid
+apes not only a superficial analogy of body and of the
+principal organs, but a close blood relationship.</p>
+
+<p class='c007'>Facts of this kind could not be foreseen when the theory
+of the simian origin of man was put forward. In spite of
+this they have arisen to confirm it in a truly astonishing
+way.</p>
+
+<p class='c007'>It is therefore impossible to doubt that man is a member
+of the group of primates having a close connection with the
+<span class='pageno' id='Page_55'>55</span>higher monkeys of the present time. This result is of great
+importance in all questions relating to human nature.</p>
+
+<p class='c007'>It would certainly be of considerable interest to know
+more exactly what steps were followed in this simian descent
+of man. On this question our knowledge is still very imperfect.
+In his researches on anthropoid apes, Selenka insists
+on a more intimate relationship between the chimpanzee
+and man. “The great resemblance of the pre-molars and
+of the molars in the permanent dentition of the chimpanzee
+with human teeth appears to indicate that the chimpanzee
+and man have a common origin, and descend from extinct
+forms like <em>Dryopithecus</em>. This conclusion, however, is contradicted
+by the fact that the milk teeth of the chimpanzee
+are much nearer those of the ourang-outang than those of
+man.”<a id='r62'></a><a href='#f62' class='c014'><sup>[62]</sup></a></p>
+
+<p class='c007'>It is evident that to clear up this question it would be
+necessary to have a greater knowledge of fossil anthropoids
+such as <em>Dryopithecus</em> and its allies. In the present state
+of knowledge only a very general hypothesis can be formulated
+as to the exact mode of human descent.</p>
+
+<p class='c007'>We have already shown that the fœtus of man and of
+the anthropoid monkeys resemble each other much more
+than the adult forms, and that the young of these apes also
+bear a greater likeness to man than do the adults. The great
+development of the skull as compared with the face is
+characteristic of young monkeys and of man young or old.
+The jaws continue to develop in the anthropoids, while in
+man there occurs in this respect a certain arrest of development.
+The hairs, so small in man, also show a similar
+arrest. Generally they remain during the whole life in a
+state of incomplete development. It is especially on the
+back of man that this feeble development of hairs occurs.
+<span class='pageno' id='Page_56'>56</span>As this part of the body in monkeys, on the contrary, is
+much more hairy than the under surface, it has been held
+to constitute an essential difference between man and
+monkeys. But embryological study enables us to settle
+this apparent contradiction. The fœtus of the gorilla examined
+by M. Deniker possessed an almost entirely smooth
+back. “The fœtus had true hairs only on the head, the
+anterior surface, and around the lips and the genital organs,
+and the eyelashes and eyebrows. The remainder of the
+body was smooth or covered with down not exceeding a
+millimetre in length.”<a id='r63'></a><a href='#f63' class='c014'><sup>[63]</sup></a></p>
+
+<p class='c007'>The skin of the under surface, smooth around the navel,
+was covered with small hairs more thickly than on the back.
+The abundance of hairs on the posterior aspect of the body
+of monkeys is a later acquisition, which develops but tardily
+during fœtal life.</p>
+
+<p class='c007'>As regards the distribution of these hairs man resembles
+much more the embryos of monkeys than adult monkeys.
+This fact, instead of shaking the theory of relationship
+between man and apes, gives us strong evidence as to the
+mode of his descent. Putting the known facts together,
+we may infer that man is a case of the arrested development
+of some simian of ancient days, as it were, a simian
+monster from the zoological point of view, although not
+from the æsthetic. Man may be regarded as a prodigy
+sprung from an ape, born with a larger brain and an intelligence
+more highly developed than occurred in his parents.
+Such a view is in accordance with known facts.</p>
+
+<p class='c007'>It must be admitted that certain kinds of organisms,
+instead of evolving at a very slow pace, spring up suddenly,
+and that in such a case nature proceeds with a considerable
+stride. Darwin foresaw this possibility, but it has been
+<span class='pageno' id='Page_57'>57</span>made plain to us by the remarkable researches of the
+botanist Hugo de Vries.<a id='r64'></a><a href='#f64' class='c014'><sup>[64]</sup></a></p>
+
+<p class='c007'>De Vries cultivated for fifteen years the Evening Primrose,
+a plant of American origin (<em>Œnothera lamarckiana</em>).
+He obtained, suddenly, a set of flowers quite distinct
+from those of the original plant. They presented such
+great differences that he could separate them as several
+quite distinct species. During the first few years De Vries
+obtained three species (<em>Œnotera lata</em>, <em>Œn. nanella</em>, and
+sometimes <em>Œn. scintillans</em>), but variation becoming more
+and more prevalent, he ultimately distinguished a dozen
+new species. These were grown from seed, and transmitted
+their specific characters to their descendants. De Vries,
+in this way, was a witness of the sudden appearance of
+new species.</p>
+
+<p class='c007'>It is probable that man owes his origin to a similar phenomenon.
+Some anthropoid ape having at a certain period
+become varied in specific characters, produced offspring
+endowed with new properties. The brain, of abnormal
+size, placed in a spacious cranium, allowed a rapid development
+of intellectual faculties much more advanced than
+those of the parent and those of the original species. This
+peculiarity would be transmitted to the descendants, and,
+as it was of very considerable advantage in the struggle
+for existence, the new race would hold its own, propagate
+and prevail. The extraordinary development of intelligence
+necessarily led to perfections in the choice of nourishment,
+perfections which approached the art of preparing
+more digestible food. The jaws, under these conditions,
+had not such a difficult task as before, and, moreover, they
+were no longer required for attack or defence. They
+became less developed than in the true anthropoid apes.</p>
+
+<p class='c007'><span class='pageno' id='Page_58'>58</span>These suggestions involve a conception of the mind that
+is in harmony with known facts. From time to time prodigies
+are born with some talent far greater than the
+gifts possessed by the parents.</p>
+
+<p class='c007'>About twelve years ago a young native of Piedmont,
+Jacques Inaudi by name, became famous in Paris on account
+of his extraordinary power of calculation. He had an
+astonishing memory for figures, and could perform mathematical
+calculations with surprising rapidity.<a id='r65'></a><a href='#f65' class='c014'><sup>[65]</sup></a> Two
+minutes were sufficient for him to multiply two numbers
+composed of seven and six figures. Other arithmetical
+calculations, such as the extraction of roots, gave him but
+little trouble.</p>
+
+<p class='c007'>To attain this result, Inaudi made use of his extraordinary
+memory for figures, founded on the persistence of auditory
+images. When he heard the numbers pronounced, he
+remembered them. Inaudi declared to the Commission
+convened by the Academy of Sciences, that when he tried
+to recall the numbers he heard them as if repeated aloud,
+in the tone of his own voice, and that he could hear them
+for the greater part of the day. “In an hour, or in two
+hours’ time, if I thought of the number that was uttered, I
+should be able to repeat it as exactly as I have done before
+the Commission.”</p>
+
+<p class='c007'>Now this very extraordinary and rare auditory memory
+was developed in an altogether abrupt way. Inaudi, the
+son of poor peasants of Piedmont, passed the first years
+of his life as a shepherd. At the age of six his wonderful
+faculty of calculating figures appeared. He did not know
+at this time how to read or to write. At eleven years of
+age he astonished the members of the Anthropological
+<span class='pageno' id='Page_59'>59</span>Society of Paris by his phenomenal memory, and it was
+only much later, at the age of twenty, that he learnt to
+read and write. Neither of the parents of Inaudi had shown
+in the slightest degree a calculating faculty like that of little
+Jacques. It must then be admitted that it was developed as
+suddenly as the new qualities in the Evening Primrose that
+we have already mentioned.</p>
+
+<p class='c007'>The first men, also, were probably ingenious children,
+born of anthropoid parents. This hypothesis very well
+explains the fact that man is more like the fœtus and the
+young of anthropoid apes than the adult animals, and
+exhibits only a trace of many organs which are much more
+developed in simian species.</p>
+
+<p class='c007'>A very distinguished German anatomist, Wiedersheim,<a id='r66'></a><a href='#f66' class='c014'><sup>[66]</sup></a>
+has given in a pamphlet a <em>resumé</em> of our actual knowledge
+of the organs of man from the point of view of their descent.
+He has found fifteen organs which show in the human
+species a considerable advance on those of anthropoid apes.
+The chief of these are the lower limb, well adapted for a
+constant erect carriage of the body; the strengthening of
+the pelvis and of the sacrum, as well as the broadening of
+the more slender pelvis of the female; the curvature of the
+lumbar part of the vertebral column; the development of
+the buttocks and of the calves; the difference of certain
+muscles of the face; the nose; certain strands from the
+brain to the spinal cord; the occipital lobe of the brain;
+the greater development of the cerebral cortex, and, lastly,
+the considerable differentiation of the muscles of the larynx
+which permit speech.</p>
+
+<p class='c007'>But besides these progressive organs, Wiedersheim has
+counted seventeen decaying organs, still able to fulfil
+their physiological function in a more or less incomplete
+<span class='pageno' id='Page_60'>60</span>manner (amongst these are the decadent muscles of the
+leg and foot; the eleventh and twelfth pairs of ribs,
+the toes, the cæcum, etc.), and not less than one hundred
+and seven rudimentary organs which serve no useful physiological
+purpose (to this category belong the coccyx—the
+vestige of a tail—the thirteenth pair of ribs in the adult,
+the muscles of the ear, the vermiform appendage, etc.).</p>
+
+<p class='c007'>We have already shown in the preceding chapter the
+great importance of rudimentary organs as aids to the
+tracing of the genealogy of organisms. These organs, useless
+at present, are the vestiges of similar but more developed
+organs, which fulfilled a useful function in our ancestors.</p>
+
+<p class='c007'>The extraordinary quantity of rudimentary organs in
+man furnishes another proof of his animal origin, and puts
+at the disposal of science information of great value for the
+philosophic conception of human nature.</p>

+apes. A comparison between even the lower races
+of man, such as the Hottentots or the aborigines of Australia
+and higher types such as the inhabitants of Europe
+and of North Africa, shows that a very great advance has
+been made.</p>
+
+<p class='c007'>Human art has been able to surpass nature in many
+instances. No natural sound is so perfect as some of the
+more beautiful pieces of modern music. Even in the production
+of form, man has triumphed over nature. Breeders
+of flowers or of birds seek to produce new varieties. With
+this object they often frame a conception of what they desire
+to produce, and, so to speak, set about to realise their programme.
+They prepare ideal images to serve them as
+<span class='pageno' id='Page_62'>62</span>guides in the process of production. By the method of
+artificial selection they often succeed in their wishes, and
+add to their collections some remarkable form. In such
+fashions aviculture and horticulture have produced birds
+and flowers more beautiful than any found in nature.</p>
+
+<p class='c007'>In regard to the human body, attempts have been made
+to surpass nature and to represent a body corresponding
+to an artistic ideal. To arrive at something more beautiful
+than man, the wings of birds or the characters of some
+other creatures have been added to his presentment. Such
+attempts have had no other result than to show that the
+human form, as created by nature, cannot be surpassed.
+The ancient conception of the human body as the artistic
+ideal has been fully justified. The views of those religious
+fanatics who have thrown contempt on the body by representing
+it in degraded forms, must be rejected.</p>
+
+<p class='c007'>It is impossible, however, to apply this result to our conception
+of the nature of man in general. The beautiful
+form of the human body appears only in youth and in
+maturity. In old age, the bodies of men and women are
+generally ugly, and in extreme old age it is almost impossible
+to see the traces of former beauty.</p>
+
+<p class='c007'>Nor can conceptions of perfection drawn from the human
+face and body be extended to the whole of man’s organisation.
+A glance at some of the organic systems will make
+this plain.</p>
+
+<p class='c007'>The human skin is covered with little hairs, the history
+of which is interesting. In one stage of embryonic life nearly
+the whole of the body is clad with hairs. This covering
+is known as the <em>lanugo</em>, and consists of strands of hair, disposed
+very regularly all over the body, save on the nose and
+the hands and feet. There is no doubt but that this is
+functionless, and is no more than an inheritance from the
+<span class='pageno' id='Page_63'>63</span>old ape-like condition. Later on, it falls out and is replaced
+by the ordinary downy covering of the body. In adult life,
+and particularly in old age, the hairs of the second coat
+tend to grow very long and so to form a covering that is
+neither beautiful nor in the least degree useful. We may
+take this as a first example of a disharmonious condition in
+the human body. Hairs, incapable of protecting the body
+from cold, survive merely as an ancestral relic and may
+become even harmful.</p>
+
+<p class='c007'>The human skin is constantly exposed to the microbes in
+dust; and the follicles of the hairs, in which these microbes
+lodge, form receptacles very favourable to their multiplication.
+In the hollows of the follicles, certain microbes,
+as for instance some of the <em>Staphylococci</em>, multiply rapidly
+and give rise to acne and to pimples. The process may
+even go the length of producing a chronic skin-disease very
+unpleasant and even dangerous if it be associated with
+suppuration.</p>
+
+<p class='c007'>In the human race, intelligence, that is to say, the activity
+of the brain, supplants many other functions, and man is
+able to protect himself against the inclemencies of weather
+much better than his furry ancestors were capable of doing.
+He is able to do this through his invention of clothing which
+may be varied with the nature of the weather. But the
+obstinate laws of inheritance burden him with a covering of
+hair, not only useless but frequently harmful. And this is
+only one example among many.</p>
+
+<p class='c007'>Although, in an extreme case, man is able to survive
+the total loss of the teeth, it cannot yet be said that teeth
+are useless or harmful. None the less, a study of the human
+dentition reveals that this set of organs is out of harmony
+with the fundamental needs of our race. The monkeys of
+the old world (<em>Catarrhines</em>), although they belong obviously
+<span class='pageno' id='Page_64'>64</span>to the brute creation, already exhibit a tendency to
+reduction in the number of teeth. While American monkeys
+(<em>Platyrrhines</em>) may possess thirty-six teeth, the old world
+forms do not possess more than thirty-two in all, at least
+as a normal occurrence. Selenka<a id='r67'></a><a href='#f67' class='c014'><sup>[67]</sup></a> has shown that among
+gorillas and ourangs individuals with a fourth pair of molars,
+bringing up the number of teeth to thirty-six, are not rare.
+He found these additional molars in 20 per cent. of one
+hundred and ninety-four adult skulls of ourangs. On the
+other hand, in the cases of the chimpanzee and the gibbon,
+the third pair of molars differ from the others in smaller
+size and occasional absence. This reduction is to be associated
+with the smaller jaws and less powerful mastication
+of these anthropoids.</p>
+
+<p class='c007'>Cases of supplementary molars are very rare in man, and
+occur more frequently in the lower races, such as negroes,
+Australians, and natives of New Caledonia.<a id='r68'></a><a href='#f68' class='c014'><sup>[68]</sup></a> On the other
+hand, absence of the third pair of molars, that is to say,
+of the wisdom teeth, is quite frequent, especially in the
+white races. Nearly 10 per cent. of Europeans throughout
+their lives have no more than twenty-eight teeth, the wisdom
+teeth being absent. This absence is more common in the
+upper jaw, where it occurs in from 18 to 19 per cent. of
+men. The loss of the wisdom teeth<a id='r69'></a><a href='#f69' class='c014'><sup>[69]</sup></a> is on the whole to be
+regarded as an advantage. Certainly from the “physiological
+point of view the part played by the wisdom teeth
+is subordinate. Their power of masticating is feeble; the
+loss does not appreciably interfere with mastication. The
+complete absence of all four has no influence on mastication.”<a id='r70'></a><a href='#f70' class='c014'><sup>[70]</sup></a>
+<span class='pageno' id='Page_65'>65</span>These teeth are cut very late, often not appearing
+until the thirtieth year and sometimes being delayed to
+extreme old age.</p>
+
+<p class='c007'>Even if they were only useless, the wisdom teeth would
+furnish an instance of disharmony in the human body. But
+these teeth often are a source of trouble which, although
+it is not often serious, may lead to grave diseases and even
+to death. No other teeth are so subject to accident. This
+is due partly to the slowness with which they develop and
+to the difficulty they encounter in cutting the mucous
+membrane. Dental caries, moreover, is specially frequent
+in them.<a id='r71'></a><a href='#f71' class='c014'><sup>[71]</sup></a> The membrane surrounding them is specially
+subject to small lesions by which the infection spreads to
+adjacent parts. Inflammatory conditions frequently arise
+from these teeth, and tumours, caries of the jaw-bone and
+even diffused suppuration, leading to death, may be sequelæ
+of wounds of the wisdom teeth. Galippe<a id='r72'></a><a href='#f72' class='c014'><sup>[72]</sup></a> has described
+a case in which one of these teeth, failing to cut the gum
+in the normal position, made its way through the cheek.
+This produced an inflammatory suppuration of the cheek
+with numerous fistulæ and an inflammation of the masseter
+muscle which made it impossible for the mouth to open.
+Notwithstanding the extraction of the wisdom tooth that
+had been the cause of all these troubles, the patient died
+of meningitis, which had started from the tooth. Other
+cases have been described in which a difficult eruption of
+the tooth led to formation of an abscess in the bone, from
+which there arose a fatal abscess of the brain.</p>
+
+<p class='c007'>Wisdom teeth may be the starting-point even of cancerous
+<span class='pageno' id='Page_66'>66</span>tumours. Magitot<a id='r73'></a><a href='#f73' class='c014'><sup>[73]</sup></a> writes that very many neoplasms of
+the jaw may be traced to a source of origin in the socket of
+the wisdom tooth.</p>
+
+<p class='c007'>There is no useful function of these teeth to set against
+their disadvantages. It was our remote ancestors, masticating
+hard food, that had the advantages of these additional
+teeth. In man they are rudimentary organs, and provide
+another proof of our simian origin.</p>
+
+<p class='c007'>The cæcal or vermiform appendage is another rudimentary
+organ in the human body, and is interesting from many
+points of view. I have already referred to its importance
+as definite evidence of our origin from lower animals, and
+shown how striking is the resemblance of the human organ
+to that of the anthropoid apes. It consists of a thick wall,
+containing glands, a muscular layer and lymphoid clumps.
+That it performs no function useful to man is made clear
+by the existence of undisturbed health in persons from whom
+it has been removed. Thanks to the advances of modern
+surgery, this organ has been removed very often, and sometimes
+even in cases where it did not appear to have been
+diseased. In a great majority of the cases, the removal
+of the organ succeeded well, and the patients experienced
+no harm, but appeared to carry on all the processes of
+digestion with equal completeness.</p>
+
+<p class='c007'>On the other hand, the cæcal appendage in man is frequently
+obliterated, there being no trace of the normal
+aperture, so that there is no connection between it and the
+general digestive cavity. According to Ribbert,<a id='r74'></a><a href='#f74' class='c014'><sup>[74]</sup></a> nearly
+one person in four possesses the appendage in an obliterated
+condition, the condition being particularly frequent in the
+<span class='pageno' id='Page_67'>67</span>aged. In young persons and infants the aperture of the
+appendage is usually open. In cases where there is no communication
+with the cavity of the digestive tract, the processes
+of digestion appear to be normal. It is logical to
+conclude that in the human being the function of the cæcum
+is either absent or very slight.</p>
+
+<p class='c007'>Even in the anthropoid apes the appendage of the cæcum
+appears to be a rudimentary structure, with a function at
+most accessory to that of the lymphoid clumps. In lower
+old world monkeys the vermiform appendage does not usually
+exist, cases such as that of <em>Cercopithecus sabaeus</em>, in which
+it is present as a little boss, being rare. It is necessary to
+seek the purpose of this structure still lower in the scale
+of life. In some herbivorous creatures the cæcum is large,
+and ends in a portion richly provided with lymphoid tissue,
+and similar to the vermiform appendage. The rabbit and
+certain marsupials are good examples. Undoubtedly, in
+their cases, the portion of the digestive canal which corresponds
+to the vermiform appendage of man is active in the
+digestion of vegetable matter. The organ is a very old
+part of the constitution of mammals, and it is because it
+has been preserved long after its function has disappeared
+that we find it occurring in the body of man.</p>
+
+<p class='c007'>Rudimentary organs for the most part display a congenital
+lack of the power of resistance, and, as Darwin
+suggested, for this reason they are frequently the seats of
+disease. When Darwin wrote his work on the “Descent of
+Man,” more than a quarter of a century ago, many fatal
+cases of inflammation of the appendage had not been recorded.
+Darwin quoted only two cases as known to him. Since
+then, appendicitis (the name given by American surgeons
+to the first acute or to the chronic inflammation of the
+appendage) has become a well-known disease in Europe and
+<span class='pageno' id='Page_68'>68</span>America, and occupies considerable space in treatises on the
+pathology of the digestive tract.</p>
+
+<p class='c007'>To give an idea of the prevalence of appendicitis, I may
+mention that in a single Paris hospital (Hôpital Trousseau)
+four hundred and forty-three cases of the disease have been
+treated in the five years 1895–1899.<a id='r75'></a><a href='#f75' class='c014'><sup>[75]</sup></a> In many of these
+cases the subjects were infants, as these as a rule are much
+more subject to appendicitis than are the aged. According
+to Treves,<a id='r76'></a><a href='#f76' class='c014'><sup>[76]</sup></a> the well-known English surgeon, 36 per cent.
+of the observed cases were under twenty years of age. Among
+old men, on the other hand, appendicitis is a rare exception.
+The varying incidence of the disease at different ages no
+doubt depends on the fact that in old age the appendage
+is often obliterated. The more easy communication with
+the other portion of the gut may be, the more chance
+there is for inflammation to occur. As it has a muscular
+layer, the appendage is able to void its fœcal contents; and
+a Scotch surgeon, Parker Syms,<a id='r77'></a><a href='#f77' class='c014'><sup>[77]</sup></a> has seen an appendage that
+he had removed, in the act of writhing about like an earthworm.
+Such movements, undoubtedly, would aid the discharge
+of the contents of the cavity.</p>
+
+<p class='c007'>The movements of the appendage, however, are usually
+feeble, and thus stagnation of the contents is common.
+Foreign matter is often found in the cavity, such as the
+pips of fruit, seeds, hairs, thorns, and in rare cases pins or
+even tin-tacks. Such bodies are capable of wounding the
+inner wall of the appendage, and so giving an opportunity
+to the microbes that abound in the digestive tube, with the
+result that microbial infection and inflammation of the
+<span class='pageno' id='Page_69'>69</span>organ is produced. Often, too, intestinal worms pass into
+the appendage and become the carriers of pathogenic
+organisms.</p>
+
+<p class='c007'>Appendicitis is usually a grave disease, and is fatal in
+from 8 to 10 per cent. of cases. It would be difficult to
+find anywhere else in the human body so flagrant a case
+of natural disharmony. The organ in question may be
+obliterated or removed without disturbance of function,
+and, moreover, in its normal condition is a frequent cause
+of serious illness!</p>
+
+<p class='c007'>The vermiform appendage is not the only part of the
+digestive canal that is out of harmony with the maintenance
+of life and health. The cæcum itself, of which the
+appendage is only a portion, is degenerating in the human
+body, as I stated in the last chapter. The human cæcum,
+in fact, is very little developed in comparison with
+the cæcum of most herbivorous animals, in which it is a
+true organ of digestion. In the human embryo the cæcum
+and the appendage are relatively better developed than they
+are in the adult.</p>
+
+<p class='c007'>Disharmony is exhibited in the human body not only
+by rudimentary organs such as the wisdom teeth and the
+appendage, or by degenerating organs such as the cæcum.
+Some very large parts of our alimentary canal must be
+regarded as useless inheritances, bequeathed to us by our
+animal ancestors. It is no longer rash to say that not only
+the rudimentary appendage and the cæcum but the whole
+of the large intestine are superfluous, and that their
+removal would be attended with happy results. So far as
+digestion goes, the latter portion of the alimentary tract is
+of little importance. Even from the point of view of absorption
+of the products of digestion its importance is strictly
+secondary. And so it is not astonishing to find that the
+<span class='pageno' id='Page_70'>70</span>removal or disappearance of nearly the whole of the large
+intestine can be supported well by man.</p>
+
+<p class='c007'>As one result of the astonishing progress of surgery, it
+has been found possible to excise certain parts of the gut,
+and particularly of the large intestine. Thus, in one case,
+Körte<a id='r78'></a><a href='#f78' class='c014'><sup>[78]</sup></a> removed, along with part of the small intestine,
+a considerable part of the large intestine, leaving in place
+only the terminal portion. The patient, who underwent
+eight successive abdominal operations, recovered. In the
+case<a id='r79'></a><a href='#f79' class='c014'><sup>[79]</sup></a> of another patient, operated on by Wiesinger, two
+coils of the large intestine (the transverse and descending
+colons) which were ulcerated, were isolated from the remainder
+of the gut, while the upper portion of the large
+intestine (the cæcum and the ascending colon) was sutured
+to the rectum. In spite of these serious interferences with
+natural structure, the patients recovered, and appeared to
+derive great advantage from the loss of the large intestine.</p>
+
+<p class='c007'>I have quoted only two out of many similar cases. However,
+apart from surgical evidence, there exists proof of the
+uselessness of the large intestine in man. The best argument
+in favour of the proposition may be drawn from the
+case of a woman who for thirty-seven years discharged
+the waste matter from the alimentary canal through an
+intestinal fistula. The latter had opened spontaneously, as
+the result of an abscess seated on the right side of the abdomen.
+Her complaint, however, had not prevented her from
+marrying, from bearing three children, nor from pursuing
+an arduous calling. The person in question, who was a
+workwoman in Varsovie, was examined by a surgeon, M.
+Ciechomski,<a id='r80'></a><a href='#f80' class='c014'><sup>[80]</sup></a> thirty-five years after the establishment of
+<span class='pageno' id='Page_71'>71</span>the fistula. The surgeon proposed to operate, hoping to
+restore her to the normal condition, and the woman consented.
+However, when the abdominal cavity was opened,
+it appeared that the large intestine had atrophied along the
+whole length, from the cæcum to the rectum; the inner
+orifice of the fistula had passed into the digestive tract
+above the cæcum, opening into the small intestine. In the
+circumstances it was impossible to close the fistula, and the
+surgeon had to close up the abdominal wall, leaving the
+patient in her former condition. The woman recovered
+rapidly, and continued her usual mode of life. She came
+under observation again two years later, but since then had
+been lost sight of. The fact that a human being was capable
+of carrying on an apparently normal life for thirty years
+in the absence of a large intestine is good proof that the
+organ in question is not necessary to man, although it has
+not yet become rudimentary. In this case again, to find
+the useful stage of the structure, we have to go to our
+remote ancestors.</p>
+
+<p class='c007'>The large intestine is much better developed in most
+herbivorous mammals than it is in carnivorous forms.
+Although it is useless in the digestion of animal food, it has
+an undisputed importance in the digestion of vegetable
+matter. It has a very large calibre in herbivorous creatures,
+and the voluminous cavity contains quantities of microbes
+which are able to digest cellulose. As cellulose is a material
+that resists the ordinary processes of digestion, it is easy
+to see the advantage derived from the harbouring of the
+microbes. It is more than probable that in the horse, the
+rabbit, and in some other mammals, that live exclusively
+on grain and herbage, the large intestine is necessary for
+normal life.</p>
+
+<p class='c007'>On the other hand, the large intestine discharges a
+<span class='pageno' id='Page_72'>72</span>function similar to that of the urinary bladder. The urine,
+which is being secreted continuously by the kidneys, accumulates
+in the large reservoir provided by the bladder.
+Similarly the waste matter from the processes of digestion
+accumulate in the large intestine and remain there for a
+longer or shorter period.</p>
+
+<p class='c007'>In studying the natural history of the large intestine,
+it striking that this portion of the gut is well developed only
+among mammals. These animals, for the most part, lead
+an extremely active terrestrial life. Most of them have to
+move about very quickly, the predacious forms in pursuit
+of their prey, the herbivorous forms to escape from their
+enemies. In such a mode of life, the need to stop in order
+to empty the intestines would be a serious disadvantage,
+and the possibility of retaining the dejecta in a large reservoir
+would be very useful.<a id='r81'></a><a href='#f81' class='c014'><sup>[81]</sup></a></p>
+
+<p class='c007'>Such are the causes that have determined the growth of
+the large intestine among mammals. Birds, which live,
+so to speak, in the air, and which do not need to arrest their
+locomotion in order to void their excreta, have no large
+intestine. Reptiles and amphibia, although they live a
+terrestrial life, do not require a voluminous large intestine,
+and such is not found among them. These animals do not
+have a fixed temperature; they are what we know as “cold-blooded,”
+and in consequence are small eaters. Most of
+them are sluggish, and do not lead an active existence like
+that of mammals.</p>
+
+<p class='c007'>In the legacy acquired by man from his animal ancestors,
+there occur not only rudimentary organs that are useless or
+harmful, but fully developed organs equally useless. The
+<span class='pageno' id='Page_73'>73</span>large intestine must be regarded as one of the organs possessed
+by man and yet harmful to his health and his life. The
+large intestine is the reservoir of the waste of the digestive
+processes, and this waste stagnates long enough to putrefy.
+The products of putrefaction are harmful. When fæcal
+matter is allowed to remain in the intestine, as in cases of
+constipation, a common complaint, certain products are
+absorbed by the organism and produce poisoning, often of
+a serious nature. Every one knows that a high temperature
+may be the result of constipation in women after childbirth,
+or in patients recovering from an operation. This
+is due to an absorption of substances produced by the
+microbes of the large intestine. Similar products may be
+the cause of an attack of acne or of other skin diseases.
+In fine, the presence of a large intestine in the human
+body is the cause of a series of misfortunes. The organ
+is the seat of many grave diseases, among which dysentery
+is notable. In some tropical climates dysentery is a
+serious scourge. According to Rhey,<a id='r82'></a><a href='#f82' class='c014'><sup>[82]</sup></a> it is “the greatest
+danger to which a European is subjected in Tonkin.
+It is responsible for more than 30 per cent. of the
+deaths caused by disease.” European troops pay it a
+large annual toll in the colonies of the French and
+English.</p>
+
+<p class='c007'>Malignant tumours seem to display a predilection for this
+region of the digestive tract. Thus, among 1148 cases of
+cancer of the alimentary tract recorded in the Prussian
+hospitals in 1895 and 1896, 1022, or 89 per cent., affected
+the large intestine, including the rectum and cæcum.<a id='r83'></a><a href='#f83' class='c014'><sup>[83]</sup></a> The
+small intestine is the only part of the digestive tract
+that is indispensable, and it is attacked to a much smaller
+<span class='pageno' id='Page_74'>74</span>extent, providing only 11 per cent. of the cases of intestinal
+cancer. The probable explanation of these facts is that
+the contents of the gut remain in the small intestine a
+shorter time than in the large.</p>
+
+<p class='c007'>Stagnation is a familiar cause of disease, and is the probable
+cause of the frequency of cancer of the stomach. Of
+10,537 cases of cancer of all parts of the digestive tract
+recorded in the Prussian hospitals in the same period, 4288,
+or more than 40 per cent., affected the stomach. The latter
+organ is one that the human body would do well to be rid of.
+It is not so useless as the large intestine, since it is the chief
+seat of digestion of albuminous substances, but the small
+intestine could take its place. Moreover, cases are known
+in which surgeons have removed cancerous stomachs.
+The results of such operations were favourable, to the extent
+that the patients survived and were able to absorb
+sufficient nourishment. They had to eat rather more
+frequently, and performed the processes of digestion
+by means of the secretions of the small intestine and
+pancreas.</p>
+
+<p class='c007'>It is not surprising to find so many instances of useless
+or harmful organs in the alimentary tract. Our ancestors
+were creatures that fed on crude and rough materials,
+such as wild plants and unprepared flesh. Man has learned
+to cultivate plants that are digested easily, and to prepare
+his meats in such a fashion as to be readily digested. The
+organs that were adapted to the mode of life of the animal
+predecessors of man have become to a large extent superfluous.
+Many creatures that have found the opportunity
+of obtaining their nutriment in a highly digestible condition
+have lost, more or less completely, the digestive organs.
+Many parasites are instances of this, as for example the
+tape-worms, which live in the human digestive tract, bathed
+<span class='pageno' id='Page_75'>75</span>by a nutritive fluid which they absorb directly; they have
+lost the digestive tract completely.</p>
+
+<p class='c007'>In the case of man such an evolution has not occurred,
+and there remains in the body a harmful organ like the
+large intestine. In consequence, it is impossible for him
+to take his nutriment in the most perfect form. If he were
+only to eat substances that could be almost completely
+absorbed, the large intestine would be unable to empty
+itself, and serious complications would be produced. A
+satisfactory system of diet has to make allowance for this,
+and in consequence of the structure of the alimentary canal,
+has to include in the food bulky and indigestible materials
+such as vegetables.</p>
+
+<p class='c007'>At this point I may refer to a topic of considerable general
+interest. Animals, in the choice of food for themselves or
+for their young, are guided by a blind and innate instinct.
+As I have shown in my second chapter, creatures like the
+fossorial wasps select only particular species of spiders or
+insects. Instinct directs them to the kind of food best
+suited to the wants of their progeny. Bees are attracted
+by the sweet juices of flowers; the silkworm instinctively
+devours the leaves of the mulberry and rejects most
+other plants. In higher animals, instinct plays the chief
+part in the choice of food. The difficulty of getting rats
+to eat poisoned food is well known; an instinct warns
+them of the danger of the material offered to them.
+In the same way dogs refrain from food that has been
+poisoned.</p>
+
+<p class='c007'>Every one has seen the minute attention bestowed by a
+monkey on food before beginning to eat it. It turns over
+what is offered, smells it carefully, cleans it, and before
+beginning to eat, subjects it to an examination that seems
+to us ridiculous. Monkeys often throw away food without
+<span class='pageno' id='Page_76'>76</span>even biting it. None the less, in spite of an instinct so
+highly developed, monkeys poison themselves with all sorts
+of dangerous substances, even when these exhale a strange
+odour. I have seen monkeys die poisoned by the phosphorus
+of matches, or even by iodoform which they had
+contrived to steal.</p>
+
+<p class='c007'>In the case of man, aberrations of instinct in the choice
+of food are common. As soon as babies begin to walk, they
+lay hold of everything and try to eat it. Bits of paper,
+lumps of sealing-wax, the mucous matter from the nose,
+all appear to them to be things to eat. Constant guard
+has to be kept to prevent them from doing themselves an
+injury. Fruits and berries they cannot resist. Cases of
+poisoning very naturally are extremely frequent, and as
+every one must know of instances, I shall mention only a
+single case. “Messrs. Beadle and Sons, oil manufacturers
+at Boston, had thrown out, from the door of their establishment,
+a quantity of castor beans that were decayed and
+useless. Some children playing in the street mistook the
+seeds for pistachio nuts, and shared them with their friends.

+<h4 class='c015'>I<br> <span class='c012'><em>Remarks on the disharmonies in the human organs of sense and perception.—Rudimentary parts of the reproductive apparatus.—Origin and function of the hymen</em></span></h4>
+
+<p class='c016'>The digestive organs are not alone amongst the parts of
+the human body in exhibiting a greater or lesser disharmony.
+More than fifty years ago, a great German physiologist,
+Johannes Müller, showed that although the human
+eye was regarded as a very perfect organ, its power of
+correction for aberration of light was poor. Helmholz,
+another famous German man of science, stated that the
+optical study of the eye brought complete disillusion.
+“Nature,” he said, “seems to have packed this organ with
+mistakes, as if with the avowed purpose of destroying any
+possible foundation for the theory that organs are adapted
+to their environment.” Not only the eye, but the other
+organs by means of which we are conscious of the outside
+world, present natural disharmony. Therein lies the cause
+of our want of certainty about the sources of our perceptions.
+Memory, the faculty that registers our mental
+processes, becomes active much later than other faculties
+lodged in the brain. If the new-born human child were
+<span class='pageno' id='Page_79'>79</span>relatively as well developed as the young guinea-pig, it is
+probable that we should know far more as to the history
+of our consciousness of the external world. But without
+lingering over the disharmonies in our senses and faculties,
+I shall pass at once to a consideration of the apparatus for
+maintaining the species.</p>
+
+<p class='c007'>I have shown that the alimentary tract, the chief organ
+involved in the maintenance of the individual life, affords
+no proof of the theory that human nature is perfect. Is it
+the case that the organs of reproduction give a better
+result? When I wished to describe the most perfect
+examples of harmony to be found amongst plants, I chose
+the mechanism by which fertilisation is accomplished in
+flowers. The persistence of the species is secured, in the
+case of flowers, by a marvellous series of structures and
+functions.</p>
+
+<p class='c007'>Is the maintenance of the human species similarly provided
+for? A detailed investigation of the male and
+female human reproductive organs shows that these contain
+parts of diverse origin. The apparatus contains portions
+of extremely ancient origin, and portions that have been
+acquired recently. The internal organs display traces of
+a remote hermaphroditism. In the male, there occur traces
+of the female apparatus, rudiments of the uterus and fallopian
+tubes. In the female, on the other hand, rudiments
+of the male structure persist. These traces date very far
+back in the history of the race, for they occur also in most
+other vertebrates. The facts seem to indicate that, at a
+very remote period, the ancestral vertebrates were hermaphrodite,
+and that they became divided into males and
+females only gradually, still retaining in each sex traces of
+the other sex. Such traces occur frequently, even in adult
+man, in the form of rudimentary organs (known as the
+<span class='pageno' id='Page_80'>80</span>organs of Weber, of Rosenmüller, and so forth). The
+rudiments not only are functionless but sometimes, as frequently
+happens with atrophied structures, form the starting-point
+of monstrous growths, or of tumours that interfere
+with health. Thus the hypertrophy of a part of the male
+prostate gland (the organ of Weber) brings about the formation
+of a <em>uterus masculinus</em>, and so produces a sort of
+abnormal hermaphroditism. The rudimentary organs in
+the male reproductive apparatus frequently are the starting-points
+of hydatid cysts. In the female, cysts such as those
+of the <em>parovaria</em> are produced by the proliferation of rudimentary
+structures. These, although usually benign, not
+infrequently become malignant. Lawson Tait,<a id='r85'></a><a href='#f85' class='c014'><sup>[85]</sup></a> a celebrated
+English surgeon, has published a case of this kind.
+He removed from a young woman a parovarian cyst that
+was apparently benign, but in six weeks symptoms of cancer
+arose, and the patient died of cancer in three months.</p>
+
+<p class='c007'>A comparison of the rudimentary organs in the human
+reproductive apparatus with those in the similar structures
+of lower animals, shows that many relics have degenerated
+further in man than in other animals. Thus the duct of
+the embryonic kidney (known as the Wolffian body) is of
+rare occurrence in adult man, although it is retained throughout
+life in the case of some herbivorous animals, in which it
+is known as Gaertner’s duct. There are, however, many
+rudimentary organs in the human reproductive apparatus,
+organs that are always useless and not infrequently more
+or less harmful to health and life.</p>
+
+<p class='c007'>Alongside organs which have been useless from time
+immemorial, the reproductive system of man possesses
+structures of recent acquisition. These deserve special
+<span class='pageno' id='Page_81'>81</span>attention, as it might have been supposed that in them
+would have been found special instances of adaptation to
+the reproductive function.</p>
+
+<p class='c007'>I have already referred (chap. iii.) to the discussions
+that have taken place over the simian origin of man. All
+attempts to demonstrate the presence in the human brain
+of parts that were absent in the simian brain have failed.
+It is a curious fact that man displays a more marked difference
+from monkeys in the structure of the reproductive
+system than in the structure of the brain. There is no <em>os
+penis</em> in man. This bone, which facilitates intromission,
+occurs in many vertebrates, not only among rodents and
+carnivora, which are widely separated from man, but in
+many monkeys, and most notably in anthropoid apes.<a id='r86'></a><a href='#f86' class='c014'><sup>[86]</sup></a> For
+some reason impossible to establish, man has lost this bone.
+It may be that certain ossifications of most rare occurrence<a id='r87'></a><a href='#f87' class='c014'><sup>[87]</sup></a>
+may represent an atavistic inheritance from our remote
+ancestors.</p>
+
+<p class='c007'>In the male sex the difference between man and the
+anthropoid ape is the loss of an organ; in the female sex
+it is the acquisition of an organ. The hymen, the physical
+indication of virginity, is peculiar to the human race. That
+organ would serve the purpose of those disputants who make
+every effort to discover the existence of a structure peculiarly
+human, far better than the posterior lobe of the brain, or
+the hippocampus minor. Bischoff<a id='r88'></a><a href='#f88' class='c014'><sup>[88]</sup></a> has determined its
+absence in the anthropoid apes, and his result has been
+<span class='pageno' id='Page_82'>82</span>confirmed by other observers. Deniker<a id='r89'></a><a href='#f89' class='c014'><sup>[89]</sup></a> failed to find
+it either in the fœtal gorilla or in the young gorilla. In
+the case of the fœtus of the gibbon, he found a slight elevation
+round the entrance to the vagina “which might be
+homologised with the hymen,”<a id='r90'></a><a href='#f90' class='c014'><sup>[90]</sup></a> but which, however, was
+not the membrane in question. Deniker<a id='r91'></a><a href='#f91' class='c014'><sup>[91]</sup></a> himself decided
+that the “membrane was absent in anthropoid apes at all
+ages.” Weidersheim, in his summary of the organisation
+of the human body,<a id='r92'></a><a href='#f92' class='c014'><sup>[92]</sup></a> also sets down the fact that “in
+monkeys a hymen is not present.”</p>
+
+<p class='c007'>The fact that this structure appears late in the development
+of the female fœtus bears out the supposition that it
+has been acquired recently by the race. According to
+several observers, who agree in this matter, the membrane
+does not develop until at least the nineteenth week of
+fœtal life.</p>
+
+<p class='c007'>Although organs very ancient in origin, and now become
+degenerate rudiments, may be useless, it is to be expected
+that an organ of recent appearance and still in a progressive
+condition, would have an important function. Of what
+utility is this membrane to a woman? Wiedersheim<a id='r93'></a><a href='#f93' class='c014'><sup>[93]</sup></a>
+remarks that its function has not been made out.</p>
+
+<p class='c007'>The hymen sometimes plays a large part in family and
+social relations, and, regarded as the evidence for virginity,
+has had moral significance bestowed on it. A minute
+examination of this structure is frequently a part of the
+judicial procedure in cases of supposed rape and so forth.
+The destruction of the hymen has led to the death of many
+hundreds of men and women.</p>
+
+<p class='c007'>From our point of view, however, it is the possible physiological
+<span class='pageno' id='Page_83'>83</span>function of this structure that is interesting. It
+seems impossible to conclude otherwise than that in existing
+races it has practically no functional value. Its atrophy
+as the result of sexual congress not only is no bar to sexual
+relations, but removes an unpleasant impediment. In
+many races the structure is removed as soon as possible.
+In some parts of China it is destroyed as part of the toilet
+of young children, and indeed many Chinese physicians are
+ignorant of its existence. A similar state of affairs occurs
+in some parts of India. In Brazil, among the tribe of
+Machacuras, virgins, in the European sense, do not exist,
+for the mothers destroy the hymen in female children soon
+after birth. In Kamchatka the aborigines regard it as
+disgraceful to be married with the hymen intact, and the
+mothers operate on their daughters.<a id='r94'></a><a href='#f94' class='c014'><sup>[94]</sup></a> Among other races,
+again, the disagreeable duty of defloration is assigned to
+special persons. Among the natives of the Philippines
+there formerly existed well-paid public officials the duty of
+whom was to destroy the virginity of the girls and so to
+make marriage pleasanter for the husbands. A similar
+custom occurs among the inhabitants of New Caledonia,
+and Moncelon states that there virginity is held in little
+esteem. “I have proof of the curious circumstance,” he
+wrote, “that when a husband shrinks from destroying the
+virginity of his wife, he employs some one from a regular
+profession to take his place.”</p>
+
+<p class='c007'>Such examples, selected from amongst many, may be
+taken as proof that even such a peculiar and recently
+acquired organ has not a physiological use.</p>
+
+<p class='c007'>On the other hand, especially among Christians and
+Mahomedans, the existence of the hymen in an intact
+<span class='pageno' id='Page_84'>84</span>condition is regarded as very important. The ancient Jews
+began to set a high value on virginity. According to the
+old Mosaic law, if, at the time of her marriage, a young girl
+were found to be no longer a virgin, “Then they shall bring
+out the damsel to the door of her father’s house, and the
+men of her city shall stone her with stones that she die;
+because she hath wrought folly in Israel, to play the whore
+in her father’s house” (Deut. xxii. 21). The religions that
+have sprung from Judaism have retained this old view
+of virginity, although in an attenuated form. Among some
+Christian peoples, material proofs of virginity at the time of
+marriage are demanded, and among some Mahomedans such
+proofs are exhibited to friends and relations on the day
+after marriage. However, the actual defloration is not
+always left to the husband, but among Arabs and Copts and
+amongst the natives of Egypt, the operation is performed
+by a specially selected matron.<a id='r95'></a><a href='#f95' class='c014'><sup>[95]</sup></a></p>
+
+<p class='c007'>It is plain, then, that this membrane is of no direct service
+in the sexual process. It may even give rise to more or
+less serious misfortune. Thus, when it is unusually rigid,
+the adjacent peritoneum may be torn and the results may
+be disastrous. Occasionally the rupture of an abnormally
+vascular membrane may give rise to bleeding of a prolonged
+and even fatal character.<a id='r96'></a><a href='#f96' class='c014'><sup>[96]</sup></a> Moreover the membrane is a
+frequent seat of ulcers, specific or otherwise.<a id='r97'></a><a href='#f97' class='c014'><sup>[97]</sup></a></p>
+
+<p class='c007'>I have already mentioned that among some races a
+rigorous toilet involves the destruction of the hymen. It
+is plain that the existence of the membrane interferes
+with strict hygiene of the vagina, especially at the periods.
+<span class='pageno' id='Page_85'>85</span>Probably some blood is retained by the membrane and
+furnishes a soil for microbes that may be dangerous to health.
+It is quite possible that certain forms of anæmia, as for
+instance the chloranæmia of virgins, may be produced by
+microbial growth. This would easily explain why marriage
+is the readiest cure for such anæmia, as marriage involves
+destruction of the membrane, and so makes possible the
+complete discharge of fluid from the vagina.<a id='r98'></a><a href='#f98' class='c014'><sup>[98]</sup></a></p>
+
+<p class='c007'>What then can be the meaning of this organ, useless as
+it is for the sexual functions, sometimes dangerous to health,
+an organ that is no ancestral heritage and that must be
+destroyed by the act of sexual union? Formerly, when it
+was accepted that characters acquired in individual life
+could be transmitted to offspring, the question was asked
+as to why this membrane had not disappeared. The
+instance was one of those which helped to overthrow the
+dogma of the inheritance of acquired characters.</p>
+
+<p class='c007'>Although it is useless to existing man, this organ may yet
+come to be explained by science. As yet we have to fall
+back on suppositions. The hypothesis which seems most
+probable is that in the earlier period of the existence of the
+human race, sexual relations were begun at a very early
+age, before the male organs were mature. Under such
+circumstances the hymen would not only not have been
+a barrier, but would have made congress more satisfactory.
+Gradually the hymen would have become dilated without
+being torn, until it was capable of admitting the adult organ.
+This hypothesis implies that in early times the membrane
+was not brutally torn, but that it was gradually dilated and
+that violent rupture is a modern necessity. In support of
+<span class='pageno' id='Page_86'>86</span>the hypothesis it may be mentioned that amongst certain
+living races sexual union begins at a very early age. In
+Ceylon, marriage takes place when the boys are from seven
+to ten years old and when the girls are from four to six
+years, according to Roer, or about eight years according to
+Beierlein. After the actual wedding ceremony the bride
+returns to the house of her parents, and it is only a few
+years later, when she is adult, that she goes to her husband.
+Roer states that he has seen cases where a father and son
+were attending school together.</p>
+
+<p class='c007'>Among the Vedas, a low caste of tropical India, boys
+marry at the age of from fifteen to sixteen years, certainly
+before the sexual organs have attained their full dimensions.
+The missionary Etern was struck with the agitation of the
+natives of Keradif (in Abyssinia) when they were ordered
+within fourteen days to marry all their boys more than
+fourteen years old to girls more than nine.<a id='r99'></a><a href='#f99' class='c014'><sup>[99]</sup></a> In Madagascar,
+in the beginning of the seventeenth century, it was
+the custom for boys to marry at an age of from ten to
+twelve years. The natives of German New Guinea marry
+their boys at the age of fourteen to fifteen. Even in
+England a law still exists permitting marriage to boys
+fourteen years old. The law is now a dead letter, but is
+evidence of the ancient practice.</p>
+
+<p class='c007'>It is known that even at the present time the hymen is
+not always ruptured in sexual congress. Budin has recorded
+its existence in seventeen per cent. of primiparous women.
+Among seventy-five cases of women in their first confinements
+he found the hymen intact in thirteen cases. Since provision
+for children has fallen on fathers these have taken
+to deferring marriage to a later age than when children
+were left to the mother. That is the probable reason why
+<span class='pageno' id='Page_87'>87</span>there are now fewer married boys. Thus, formerly, the
+proportion of women who at the first childbirth still possessed
+unruptured hymens, was much greater, and it is not
+difficult to suppose that in still earlier times such a condition
+was normal. It is plain that there is here an instance of
+a very recently acquired disharmony.</p>
+
+<p class='c007'>The homology between certain portions of the male and
+female reproductive apparatus is well known. The male
+homologue of the female hymen is a little fold that hinders
+the mingling of urine with the seminal fluid during emission,
+and that is known to anatomists as the <em>caput gallinaginis</em>
+or <em>colliculus seminalis</em>. It is very much smaller than
+the hymen, so that we cannot regard the latter as a rudimentary
+homologue of a useful organ. However, the prepuce
+of the male is a clear instance of the presence in the
+male organs of useless parts. It is removed by circumcision
+among very many races, such as the Hebrews and Arabs,
+and other Mahomedans, and amongst Persians, negroes,
+Hindus, Tartars, and its absence seems to bring about no
+inconvenience.</p>

+
+<p class='c016'>Notwithstanding their imperfections, the human organs of
+reproduction are able to fulfil their functions. A close
+scrutiny, however, shows that there are many sides on
+which they are disharmonious or badly adapted.</p>
+
+<p class='c007'>The occurrence of bleeding is usually a sign of disease.
+<span class='pageno' id='Page_88'>88</span>Bleeding from the nose or of the lungs or intestines or
+kidneys is an indication of disease more or less serious.
+Discharge of blood from the female reproductive organs
+may also be an indication of disease, as for instance when
+due to tumours of the uterus. The only exception to the
+rule is the periodic flow in the case of women, by which they
+lose hundreds of grammes of blood (100 to 600 gr.). There
+is something paradoxical in such a physiological occurrence,
+and it deserves minute consideration.</p>
+
+<p class='c007'>These periodic losses, unlike the possession of a hymen,
+are not a peculiarity of the human female. “Heat” in
+lower animals is analogous, although in that case the chief
+indications are swellings of the mucous membrane with a
+slight discharge of fluid, hardly tinged with blood. The state
+indicates the awakening of the sexual instinct and readiness
+for coition.<a id='r100'></a><a href='#f100' class='c014'><sup>[100]</sup></a> Among monkeys there has been observed a
+flow much more closely resembling that of woman. In the
+case of macaques and cercopitheci, it has been observed
+even that the flow is monthly. Heape,<a id='r101'></a><a href='#f101' class='c014'><sup>[101]</sup></a> while in British
+India, took advantage of a valuable opportunity for making
+observations on this subject.</p>
+
+<p class='c007'>Among two hundred and thirty females of <em>Macacus rhesus</em>
+of which the greater number were adult or nearly so, seventeen
+displayed signs of menstruation, consisting of a swelling
+of the genitalia accompanied by the discharge of a pale and
+viscid fluid. Usually the flow assumed a pale rose tint, due
+to the presence in it of blood corpuscles, but cases where
+it was highly coloured were rare.</p>
+
+<p class='c007'>Although they are distinctly analogous to the menstrual
+<span class='pageno' id='Page_89'>89</span>flows of women, these occurrences in monkeys are distinguished
+by the predominance of the swelling of the genitalia,
+the viscid character of the discharge, and the relative
+absence of blood. They present a condition intermediate
+between the “heat” of lower animals and the human
+phenomena.</p>
+
+<p class='c007'>In anthropoid apes a similar menstruation has been
+observed. Bolau, Ehlers, and Hermes, record it in the case
+of the chimpanzee. “At this period,” wrote Hartmann,<a id='r102'></a><a href='#f102' class='c014'><sup>[102]</sup></a>
+“swelling and reddening of the genitalia occurred. The
+labiæ majores, which are usually inconspicuous, enlarged
+greatly, and a similar increase took place in the labiæ minores
+and the clitoris.”</p>
+
+<p class='c007'>In the case of women swelling of the genitalia is very
+slightly marked, and the chief occurrence is the flow of
+blood. It is plain, then, that something new has been
+acquired in the menstruation of women.</p>
+
+<p class='c007'>The condition of the flow at the present time is probably
+the result of modifications acquired recently in the history
+of the race. Among primitive peoples sexual union occurred
+at a very early age, and pregnancy occurred before menstruation.
+The latter did not appear during pregnancy nor in
+the time of suckling, and probably the latter was hardly
+over before a new pregnancy had occurred. In that way
+there was no opportunity for the onset of menstruation.</p>
+
+<p class='c007'>The human capacity for procreation throughout the year
+made the race extremely prolific. Probably this prolificness
+is the reason why man has spread over the surface of the
+earth, and has multiplied so enormously, in spite of the
+barriers to his progress and the high rate of mortality to
+which he is subjected.</p>
+
+<p class='c007'><span class='pageno' id='Page_90'>90</span>Instances are known from recent observation of pregnancies
+occurring before the onset of menstruation. According
+to Rhode, among the Guatos, Indians inhabiting the
+mouth of the Rio Sâo Lourenzo in Paraguay, married women
+not more than five to eight years of age are to be met with,
+and these must have married before menstruation. Among
+the Vedas of tropical India, girls marry before they are nine
+years of age, and have relations with their husbands before
+sexual maturity. In Chiras in Persia, girls marry before
+puberty, and while their chests are still flat. In Syria,
+according to Robson, girls marry at the age of ten, and so
+before puberty. Du Chaillu related that the Achira of
+West Africa did not defer marriage until after the appearance
+of puberty. Abbadie, while on his voyage in Nubia,
+found that men bought young girls and had sexual relations
+with them before the time of menstruation. Among the
+Atjeh of Sumatra, girls marry at an age certainly before
+that of puberty, as they have hardly lost their first set of
+teeth. Although the husbands are a few years older, they
+are still unfitted for sexual union. The couples sleep together,
+and attempt sexual union before they are fitted for it.
+Among the islanders of Viti, again, marriage takes place
+before puberty.</p>
+
+<p class='c007'>The ancient Hindoos married at a very early age. Bötlingk
+quotes from the Sanscrit poems in which hell was
+awarded to the fathers of girls who had not been married
+when puberty came on. In other verses it was written
+that not only the father but also the mother and the elder
+brother were to be carried down into hell if the daughter
+began to menstruate before she had been married; the girl
+herself was to descend to the lowest degree of Çûdrâ, and
+was never to be taken as a wife.</p>
+
+<p class='c007'>There is no doubt as to the possible fertility of marriages
+<span class='pageno' id='Page_91'>91</span>contracted at these early ages. Polak<a id='r103'></a><a href='#f103' class='c014'><sup>[103]</sup></a> gives examples
+taken from Persia. It is not necessary for impregnation that
+it should have been preceded by a menstrual flow. Facts
+making this clear have occurred not only in warm climates
+but in our own latitude. Rakhmanoff,<a id='r104'></a><a href='#f104' class='c014'><sup>[104]</sup></a> in Russia, attended
+in childbirth a woman not more than fourteen years of age,
+of poor constitution, and badly nourished, and with features
+still infantine. Menstruation had not yet taken place; the
+confinement was normal.</p>
+
+<p class='c007'>It is reasonable to suppose that in former times these
+early marriages of girls under the age of puberty were more
+common, if indeed they were not customary. In such circumstances
+menstruation would have been a rare phenomenon.</p>
+
+<p class='c007'>It must be remembered that the examples of menstruation
+observed in the case of monkeys were taken from creatures
+living in abnormal conditions, isolated in zoological gardens
+and passing their lives in captivity. It is highly probable that
+the periods as they exist to-day, with copious sanguineous
+discharge, are a recent acquisition of the human race.</p>
+
+<p class='c007'>As he emerged from the primitive condition man had
+to restrain his prolificness. The history of savages and of
+civilisations shows that progress and culture have been
+accompanied by a rise in the age for marriage. In this way
+the menstrual periods could develop without check, and
+attain the present condition. In these circumstances it is
+not wonderful that menstruation should appear so abnormal
+and even pathological. A copious discharge of blood, preceded
+and accompanied by pain and by nervous and mental
+distress as so frequently happens, has no apparent kinship
+with the processes of normal life.</p>
+
+<p class='c007'><span class='pageno' id='Page_92'>92</span>It is now easy to see why among so many races there are
+special rules made for women during this period. Most of
+the races of the earth, says Ploss, regard menstruating
+women as impure. The occurrence is so widespread that
+it is unnecessary to adduce particular cases, but a few with
+some point of special interest may be noticed. Thus, among
+the Hindoos a high-caste woman is regarded as a pariah in
+the first day of the period, and as one of the murderers of
+Buddha on the second day. Among many races a woman
+in this condition is forbidden to come near men, or to touch
+a number of objects, as she is regarded as capable of setting
+up many diseases and of doing serious damage. The Germans
+of the eighteenth century believed that the hair of a menstruating
+woman buried in manure would engender snakes.</p>
+
+<p class='c007'>It is not surprising that the origin of menstruation has
+been attributed frequently to evil spirits. The Iranians held
+that it appeared first in Dchahi, the goddess of immorality.<a id='r105'></a><a href='#f105' class='c014'><sup>[105]</sup></a>
+Such opinions implied vaguely that there was something
+abnormal in the process. The history of the evolution of
+menstruation explains well the origin of such a notion.</p>
+
+<p class='c007'>Another bizarre and apparently abnormal feature of the
+reproductive processes receives explanation in the history
+of its evolution. The feature in question is the painfulness
+of childbirth. It is truly astonishing and singular to find
+a phenomenon essentially normal from the point of view
+of physiology accompanied by pain of so marked a character.
+No doubt other animals suffer during labour, but
+among the mammalia woman undergoes the severest pain.</p>
+
+<p class='c007'>Observations made on several Europeans who have been
+brought to bed at an abnormally early age have shown
+that, contrary to all expectation, parturition was easy and
+the sequelæ normal.<a id='r106'></a><a href='#f106' class='c014'><sup>[106]</sup></a> Moreover, Dr. Dionij has stated his
+<span class='pageno' id='Page_93'>93</span>opinion that of two cases of a first childbirth at the ages
+respectively of fifteen and of forty years, he would prefer
+the earlier age. The daughters of the colonists in the
+Antilles were accustomed to marry at very early ages. In
+1667 Du Tertre related that a young woman of that region
+had informed him that the birth of her first child took place
+when she was twelve years and a half of age, and that the
+process lasted no more than a quarter of an hour and
+had been painless. The missionary Beierlein practised for
+long in Madras, where marriages were very early, and found
+that parturition was much more easy than in Europe.<a id='r107'></a><a href='#f107' class='c014'><sup>[107]</sup></a></p>
+
+<p class='c007'>On the other hand, certain facts show that too young
+mothers are subject to a very heavy rate of mortality during
+childbirth, and soon after it. The most salient fact in this
+connection is furnished by Hassenstein, who has stated that
+the mortality of labour cases in Abyssinia is 30 per cent.,
+and who has attributed this death-rate to the circumstance
+that marriage takes place before the body of the woman is
+sufficiently developed.<a id='r108'></a><a href='#f108' class='c014'><sup>[108]</sup></a> In British India the disadvantages
+of precocious marriage have been repeatedly urged;
+and in a petition relating to this subject, Dr. Mansell referred
+to the case of a woman of twelve years of age in whom
+parturition was interfered with by the undeveloped condition
+of the pelvis, so that the head of the child had to be
+destroyed.</p>
+
+<p class='c007'>Matthews Duncan, the well-known English obstetrician,
+paid much attention to the mortality of labour cases, with
+the object of deciding the best age for marriage. He came
+to the conclusion that women from twenty to twenty-four
+years of age were best fitted for labour, that is to say, showed
+the lowest rate of mortality during labour or as a result of
+labour. He also showed that such women were most fertile,
+<span class='pageno' id='Page_94'>94</span>and that the development of the pelvic bones was completed
+at that period of life. Women who were of a lower or
+higher age showed a greater mortality rate in connection
+with childbirth.</p>
+
+<p class='c007'>The facts of which I have just given a summary lead
+directly to a most striking instance of disharmony exhibited
+in the order of the development of the human reproductive
+apparatus. Puberty declares itself in a woman by the
+beginning of menstruation at a time when girls still possess
+infantile characters and when the bones of the pelvic basin
+are not yet fully developed. Obviously there is a disharmony
+between puberty and the general maturity of the body,
+that is to say, the nubile condition.</p>
+
+<p class='c007'>This disharmony becomes still more evident upon a closer
+examination of the phases of development of the different
+reproductive functions. In the human race, reproduction
+is brought about by the union of the sexes suggested by
+sympathy or mutual love. The sexual union makes it
+possible for the male elements or spermatozoa to reach the
+eggs and fertilise them by passing into them. It might
+have been expected that the different steps in the process
+would have been attuned so as to act in harmony. As a
+matter of fact there is no such relation. The different
+factors of the sexual function develop independently and
+unharmoniously.</p>
+
+<p class='c007'>Love and the sexual sense in the human race appear
+before the other factors in the process. Ramdohr,<a id='r109'></a><a href='#f109' class='c014'><sup>[109]</sup></a> in the
+eighteenth century, stated that little boys frequently exhibit
+amorousness towards women. They are capable of being
+strongly affected by jealousy and by desire of exclusive
+possession of the coveted woman. This fact is well known,
+and has been related of famous personages. Thus Dante,
+<span class='pageno' id='Page_95'>95</span>at the age of nine, fell in love with Beatrice; Canova was in
+love when he was little more than six years of age, and Lord
+Byron was in love with Mary Duff at the age of seven.<a id='r110'></a><a href='#f110' class='c014'><sup>[110]</sup></a></p>
+
+<p class='c007'>Sexual excitability appears at an age when there is no
+question but that the sexual elements are undeveloped. In
+infants still in the cradle, observers have noticed movements
+and attitudes showing the presence of sexual excitability.
+Curschmann and Fürbringer,<a id='r111'></a><a href='#f111' class='c014'><sup>[111]</sup></a> both competent clinicians,
+have noticed these feelings in children under the age of
+five. Later on in life, the development of the sensibility
+is more common, and is practically universal among boys
+before the time at which the spermatozoa are ripe.</p>
+
+<p class='c007'>This disharmony is the cause of onanism, which is common
+everywhere among boys. Before ordinary sexual congress
+is possible for them, boys experience the characteristic
+pleasure of the sexual sensations, and by a kind of natural
+instinct learn self-gratification. Onanism is sometimes
+defined as a “gratification of the sexual desire by unnatural
+means.”<a id='r112'></a><a href='#f112' class='c014'><sup>[112]</sup></a> But it is man’s constitution itself that permits
+the development of the sensation precociously, before the
+development of sexual maturity. Letourneau is right when
+he says that such sexual aberrations are abnormal, but not
+unnatural, as they occur among animals.</p>
+
+<p class='c007'>In the case of young boys the habit is so common that,
+according to Christian,<a id='r113'></a><a href='#f113' class='c014'><sup>[113]</sup></a> “very few are able to say that
+they have avoided it completely.” The same writer asks
+the question: “If it be remembered that onanism among
+certain peoples, at certain times, has been recognised as an
+<span class='pageno' id='Page_96'>96</span>ordinary event, it is difficult to avoid asking if there be
+not a latent vice, hidden in the depths of human nature, and
+ready to be provoked into activity by very small causes?”
+The answer is sufficiently plain. The cause of onanism,
+this “vice” or “crime,” as Tissot and other authors have
+called it, undoubtedly is the result of a natural disharmony
+in the human constitution, of a premature development of
+sexual sensation. Among the most civilised races and the
+lowest savages the mode of satisfying the premature demand
+is equally common.</p>
+
+<p class='c007'>It is to be noticed that onanism is more common and
+earlier developed in the male sex. The development of
+sexual irritability in the female occurs very irregularly. In
+some races onanism is so much a custom among little girls
+that no attempt is made to conceal the practice. This occurs,
+for instance, among certain Hottentot tribes, and is referred
+to openly in talk and legends.<a id='r114'></a><a href='#f114' class='c014'><sup>[114]</sup></a> Similar instances occur
+elsewhere, but in most races the practice is thought wrong,
+and is concealed as much as possible.</p>
+
+<p class='c007'>Among girls,<a id='r115'></a><a href='#f115' class='c014'><sup>[115]</sup></a> onanism is less frequent than in the case
+of boys, a circumstance in relation with the fact that sexual
+sensation usually appears much later in the female sex. It
+is almost a general rule that girls who have arrived at sexual
+maturity have not acquired sexual irritability, while to
+many it comes only gradually after marriage. Sometimes
+it does not occur until after the first child has been born.
+On the other hand, love begins very early in young girls,
+although it long retains a platonic character and is not
+associated with sexual sensation until much later.</p>
+
+<p class='c007'><span class='pageno' id='Page_97'>97</span>The maturity of the spermatozoa in the male comes long
+after the development of sexual irritability and of love.
+None the less, it comes before the organism of the male
+is actually ready. It happens, in consequence, especially
+among the highly civilised peoples, that marriage and
+regular unions are impossible at the right time. The youth
+has his education to finish, his profession to choose, and he
+must be ready to support children before he is able to
+marry. As civilisation advances, the age of marriage
+becomes later and later. In the case of Europeans, sexual
+maturity occurs in the male at the age of twelve to fourteen
+years, while the average age at the first marriage is shown
+in the following table:—</p>

+</table>
+
+<p class='c021'>These figures show clearly what a gap there is between the
+coming of sexual maturity and the age at which marriage
+can be undertaken.</p>
+
+<p class='c007'>The decay of the reproductive functions shows a series
+of disharmonies similar to those that occur during development.
+Spermatozoa continue to be formed throughout the
+greater part of the life of a man, and may still be found
+even in very old men. Pawloff, for instance, discovered
+that they were present in abundance in the case of a man
+at the age of ninety-four, and this observation is not unique.<a id='r117'></a><a href='#f117' class='c014'><sup>[117]</sup></a>
+<span class='pageno' id='Page_98'>98</span>But the presence of ripe spermatozoa is not the only condition
+necessary for functional virility. In the case of old
+men it happens frequently that there is incapacity to make
+normal use of the spermatozoa that are produced. This
+brings about a series of discomforts in the sexual functions
+of advanced life which, however, do not prevent the retention
+of the specific sensation and desire until a very extreme
+old age. Doctors, in hospitals devoted to old men, have
+noticed to what an extent their patients are engrossed by
+sexuality. Even some of the ancient authors have noticed
+how the amorous sentiments of old men turn into a perverted
+attraction to youths.</p>
+
+<p class='c007'>Sexual irritability and amorousness not only appear
+before sexual maturity and general fitness of the organism
+for marriage, but they remain after the disappearance of
+these. It is remarkable to notice how profound is the difference
+between the disharmonies of the reproductive functions
+in man and the perfect condition of adaptation of the same
+functions in the higher plants. In the case of the higher
+plants, as I described in my second chapter, the arrangements
+are complicated on account of the necessary mediation
+of insect life. Notwithstanding this, the perfection of
+the adaptation is remarkable. At the exact time when the
+reproductive products are ripe, the petals open and the
+nectar is secreted, while, in addition, at this time many
+flowers discharge odours agreeable to insects. Attracted by
+the scents and colours, the insects visit the flowers in quest
+of pollen or nectar, and, becoming dusted with pollen, carry
+it to the stigmas of the next flowers they visit. As soon as
+<span class='pageno' id='Page_99'>99</span>fertilisation has taken place the petals fade, the scents are
+no longer produced, and the insects cease to visit the flowers
+to which they are no longer necessary.</p>
+
+<p class='c007'>It is not surprising that the disharmonies in the human
+reproductive apparatus are a frequent source of trouble.
+Little children, in whom sexual irritability has awakened
+prematurely, learn to satisfy it by means called “unnatural.”
+In many cases damage rapidly follows. “In the child,”
+wrote Dr. Christian, “there is no secretion of spermatozoa,
+and it is in the child that the results of onanism are most
+disastrous to the organism, and disastrous almost in inverse
+proportion to the age.<a id='r118'></a><a href='#f118' class='c014'><sup>[118]</sup></a> It is in early infancy that this aberration
+merits the evil reputation that it has acquired; it
+compromises health, intelligence, and even life. Quite
+young children wither, becoming pale, stupid, and fragile,
+when they have acquired this disastrous habit. The evil
+is almost entirely a consequence of the unripeness of the
+organism for sexuality.” Happily these evil occurrences
+are rare.</p>
+
+<p class='c007'>A publication by Tissot, a Swiss doctor, on the subject of
+onanism, made a sensation in the eighteenth century. The
+book was full of exaggeration, and it was very inexact, but
+it contained interesting confessions from persons who had
+contracted the habit. A woman wrote to Tissot in the
+following terms: “But for the restraint of religion, I should
+have put an end to my life, which is ruined by my own fault.”
+Not infrequently the vice leads to melancholia.</p>
+
+<p class='c007'>Other unfortunate results come from the ripening of the
+sexual products before the organism is ready for marriage,
+and before the character has been formed. As men cannot
+contract marriage before they are ready for it, irregular and
+frequently harmful sexual aberration may occur.</p>
+
+<p class='c007'><span class='pageno' id='Page_100'>100</span>The survival of this specific irritability until too late a
+period of life is another source of disaster. Old men who
+can neither excite passion nor satisfy it, often become
+victims of their own amorousness and unassuaged passions.
+It has been shown that passion may survive after the complete
+atrophy of the functions of the organs. Similarly it
+is the case that women from whom the ovaries have been
+removed, may continue to retain sexual irritability completely.</p>
+
+<p class='c007'>Disharmony of sexuality may also occur between persons
+of different sexes. The fact that sexuality is usually more
+precocious in the male sex often produces a disharmony in
+the case of married persons. At the time when a woman
+is still in full possession of this specific irritability, the appetite
+in the man may be on the wane. From this disharmony
+there often follows conjugal infidelity or passion between
+persons of the same sex.</p>
+
+<p class='c007'>Schopenhauer devoted attention to this subject and wrote
+as follows: “That nature herself may produce a condition
+totally opposed to the natural function offers a paradoxical
+problem of very deep interest.”<a id='r119'></a><a href='#f119' class='c014'><sup>[119]</sup></a> It is clear, however, when
+we consider the disharmonies in the development and activities
+of the functions in question, that the apparently
+paradoxical and strange aberrations of sexuality are natural
+enough.</p>
+
+<p class='c007'>The existing disharmony gives rise to many evils from
+earliest youth to advanced age, and, consequently, it is
+not surprising to find that religions have denounced sexuality
+more or less severely. Dr. Christian expresses his
+astonishment “that in nearly all religions it has been
+considered a homage to the Deity to abstain from sexual
+<span class='pageno' id='Page_101'>101</span>intercourse.”<a id='r120'></a><a href='#f120' class='c014'><sup>[120]</sup></a> It is simply because the disharmonies
+of sexuality lead to sexual aberrations that religions have
+found cause for denouncing human nature as vile.<a id='r121'></a><a href='#f121' class='c014'><sup>[121]</sup></a></p>
+
+<h4 class='c015'>III<br> <em>Disharmonies in the family instincts.—Artificial abortion.—Desertion and infanticide.—Disharmonies in the social instincts.</em></h4>
+
+<p class='c016'>As the functions of reproduction are seated deep in the
+organic world and none the less present cases of striking
+disharmony in mankind, it is not surprising to find similar
+want of adaptation in the family instincts of man, as these
+instincts have been acquired more recently and are less
+widespread in the living world.</p>
+
+<p class='c007'>It has been shown that the animal world provides many
+examples of onanism and of aberrations of sexual congress.
+On the other hand, there are no cases in the animal world
+in which pregnancy is destroyed by aberrant instincts.</p>
+
+<p class='c007'>To the human race belongs the distinction of having
+invented modes of sexual congress which are necessarily
+barren. No doubt the loss of the <em>os penis</em> has made such
+occurrences more easy, as the presence of that bone would
+render interruption of coition more difficult. But there are
+many ways in which the spermatozoa may be prevented
+from accomplishing their function, and these are so common
+and so familiar that it is unnecessary to enumerate them.
+In civilised countries procreation is limited chiefly by such
+means. In its early days, the human race must have been
+distinguished by its unusual procreative capacity, but with
+the growth of civilisation many devices have been employed
+to limit that.</p>
+
+<p class='c007'><span class='pageno' id='Page_102'>102</span>Savages and races of low civilisation have recourse to
+artificial abortion rather than to means for preventing
+fertilisation, and abortion is almost universal among them.</p>
+
+<p class='c007'>The great treatise of Ploss, “Das Weib,” to which I
+have made repeated reference, contains a whole chapter<a id='r122'></a><a href='#f122' class='c014'><sup>[122]</sup></a> on
+this subject. Deliberate abortion with the object of limiting
+the number of children is customary all over the globe.
+In most primitive races and among peoples of low civilisation
+it is practised openly without the smallest restraint.
+Many of these peoples have adopted the custom of limiting
+the family to two children by procuring abortion in subsequent
+pregnancies. The aborigines of Kaisar and of the
+islands of Watubela observe the rule strictly. Among the
+natives of the islands of Aaru it is rare to find more than
+three children in a family, because any others are destroyed
+by artificial abortion.</p>
+
+<p class='c007'>A similar custom is widespread in India, being quite as
+common among the Hindoos who are ruled by England as
+among independent races. In the peninsula of Kutch,
+women frequently procure abortion, and one woman boasted
+to Macmurdo that she had made use of the practice five
+times. Abortion is equally common in Africa and America.</p>
+
+<p class='c007'>Even in Europe there are nations amongst which abortion
+is permitted within certain limits. The Turks do not
+regard a fœtus as being really alive until after the fifth
+month, and have no scruple in causing its abortion. Even
+at later stages, when the operation becomes criminal, it is
+frequently practised. In 1872, at Constantinople, more than
+three thousand cases of abortion were brought before the
+Courts in a period of ten months. Under such circumstances
+it is not surprising that illegitimate children are
+rare in the East.</p>
+
+<p class='c007'><span class='pageno' id='Page_103'>103</span>Artificial abortion is not a modern invention, but was
+common in ancient times. The old Greeks practised it
+openly, without any legal restraint. Plato regarded it as
+within the province of the midwife, and Aristotle permitted
+it to married people when a pregnancy that was not desired
+took place.</p>
+
+<p class='c007'>Steller, writing of the natives of Kamchatka of the
+eighteenth century, stated that among them marriage was
+contracted rather for sensual gratification than for the
+procreation of children, because they interfered with pregnancies
+by various kinds of medicaments and by violent
+operative interferences.</p>
+
+<p class='c007'>The arts by which abortion has been produced are numerous
+and varied. In addition to the administration of drugs,
+chiefly of vegetable origin, implements have been employed.
+The natives of Greenland use the ribs of seals or of the
+walrus, and the Hawaians of the Sandwich Islands employ
+for the purpose a wooden implement fashioned as a deity.</p>
+
+<p class='c007'>On the other hand, certain races have strongly opposed
+the practice of abortion. In the ancient world such races were
+the Medes, the Bactrians, the Persians, and Jews. Among
+the ancient Incas, abortion was a crime punished with death.
+Later on, the Christian nations followed this view. However,
+the reprobation of abortion occurs only in a comparatively
+small number of the nations of the earth, and even amongst
+these the practice is common in secret.</p>
+
+<p class='c007'>Animals which are unable to procure abortion very often
+destroy their young, as I described in the second chapter
+of this volume. In the human race, infanticide is too
+common. The Greeks and Romans did not regard the
+newly born infants as possessing any right to live. The
+old Germans held themselves free to expose their infants.
+The Arabs, before the faith of Islam had spread to them,
+<span class='pageno' id='Page_104'>104</span>were in the habit of burying many female children alive.
+In India a similar custom is common, and in China it is
+notorious. According to figures collected by Eitel,<a id='r123'></a><a href='#f123' class='c014'><sup>[123]</sup></a> the
+Chinese of the province of Canton very often kill female
+children immediately after birth. “It may be said,” he
+wrote, “that the murder of female infants is the general
+rule among the Hak-lo, and especially among the Hak-ka
+of the agricultural classes. The Hak-ka themselves estimate
+the number of female children exposed as about two-thirds
+of those born.” In a little village in which the author
+lived for several years, an investigation, made with the help
+of some Christians, showed that without exception women
+who had given birth to two children had killed at least one
+of them.</p>
+
+<p class='c007'>In Tahiti two-thirds of new-born children are killed,
+those of the female sex making up the greater part of the
+numbers. The first three infants and all twins are killed,
+and as a rule not more than two or at most three are actually
+reared.<a id='r124'></a><a href='#f124' class='c014'><sup>[124]</sup></a> Among the Melanesians the custom of infanticide
+is very common. “It must also be assumed,” said Ratzel,<a id='r125'></a><a href='#f125' class='c014'><sup>[125]</sup></a>
+“that in Ugi (Solomon Islands) all the infants are killed, to
+be replaced by the Bauros.”</p>
+
+<p class='c007'>It is not surprising that such a widespread occurrence of
+artificial abortion and of infanticide among primitive races
+is bringing about a rapid diminution in the numbers of
+these, and may lead even to their extinction. This is taking
+place in the case of the natives of New South Wales, of
+New Guinea, and of the islands of Aaru. Nothing could
+show more plainly the feebleness of the human family instinct.
+<span class='pageno' id='Page_105'>105</span>In more highly civilised nations, the rude proceedings of
+savages have been replaced by clever devices to prevent
+conception, and infanticide has become rare. Artificial
+abortion is excited by modern methods suggested by the
+progress of science. The embryonic membranes are pierced
+not by the ribs of seals or hair-pins, but by sterilised sounds,
+and the operation is performed with strict asepsis. In averting
+the natural results of passion the woman is subjected to
+the smallest possible risk.</p>
+
+<p class='c007'>It is indubitable that more than one race has perished
+because of its lack of the instinct of family. However, it
+need not be feared that the human race itself will disappear
+because of the failure of procreation. But it is plain that
+the readiness with which devices to prevent the production of
+children have been adopted shows the weakness of the family
+instinct in man, and opens up a problem to which the attention
+of moralists and legislators may well be directed.</p>
+
+<p class='c007'>The family instinct is deeply seated, as it arose among
+animals more ancient than man; none the less it exhibits
+disturbances and aberrations in the human race capable of
+bringing about the extinction of peoples or nations. It is,
+however, strong enough to secure that man will persist in
+the future.</p>
+
+<p class='c007'>Man certainly is a social animal, but the instinct impelling
+him towards union with his fellows is of recent origin. Such
+animal societies as are to be found among insects are not
+comparable with human associations. Among mammals, the
+nearest allies of man, the social instincts are developed only
+to a slight extent, and even the anthropoid apes show very
+little progress in this direction. Many of these creatures
+have shown in captivity the aptitude to become friendly
+with man or with other animals, and thus have displayed
+the beginnings of the capacity to form societies. But, in
+<span class='pageno' id='Page_106'>106</span>the wild condition, anthropoids live only in families, and
+these contain few individuals. As regards the social capacities
+of the chimpanzee Dr. Savage wrote:<a id='r126'></a><a href='#f126' class='c014'><sup>[126]</sup></a> “They cannot
+be called gregarious, seldom more than five, or ten at most,
+being found together. It has been said on good authority
+that they occasionally assemble in large numbers in gambols.
+My informant asserts that he saw once not less than fifty
+so engaged; hooting, screaming, and drumming with sticks
+on old logs, which is done in the latter case with equal
+facility by the four extremities.”</p>
+
+<p class='c007'>We have little acquaintance with the social life of the
+anthropoids, but, so far as we know, these creatures present
+only the merest beginnings of the social instinct. Man has
+moved much beyond them in that direction. Even the
+lowest races and the most primitive of living peoples such
+as, for instance, the Bushmen or the aborigines of Australia,
+display a well-developed social instinct.<a id='r127'></a><a href='#f127' class='c014'><sup>[127]</sup></a></p>
+
+<p class='c007'>The universal presence of the social instinct among human
+beings would seem to afford the basis of a happy life. In
+the numerous attempts made to find a purely rational
+principle that may serve as the basis for morality without
+the intervention of supernatural sanction, abundant use has
+been made of man’s craving to live in association with his
+fellows. Those who have tried to deduce moral law from
+the essential constitution of man have relied largely upon
+the innate sympathy between man and his fellows. Such
+a line of argument is so common and has been employed so
+frequently that I need not spend much space in developing
+it. I shall limit myself to a few examples.</p>
+
+<p class='c007'>Towards the end of last century Büchner,<a id='r128'></a><a href='#f128' class='c014'><sup>[128]</sup></a> a German
+<span class='pageno' id='Page_107'>107</span>physician, published a materialistic code of morality that
+made a considerable sensation. He wrote as follows on the
+question now before us: “What we term the moral sense
+arose from the social instincts and habits which, under pain of
+extinction, are developed in every society of men and animals.
+Morality depends on sociability, and varies with the
+peculiar conditions of each particular association. As man
+is essentially a social animal, and to be regarded, apart from
+society, merely as a wild beast, it is plain that the needs of
+the community must impose on him certain restrictions and
+directions that in time will pass into a settled code of morals.”</p>
+
+<p class='c007'>Half a century later practically the same idea was
+repeated. Haeckel,<a id='r129'></a><a href='#f129' class='c014'><sup>[129]</sup></a> the well-known German naturalist,
+expressed it as follows in a volume that appeared a few
+years ago:—</p>
+
+<p class='c007'>“Modern science shows that the feeling of duty does not
+rest on an illusory ‘categorical imperative,’ but on the solid
+ground of social instinct, as we find it in the case of all the
+social animals. It regards as the highest aim of all morality
+the re-establishment of a sound harmony between egoism
+and altruism, between self-love and the love of one’s neighbour....
+If a man desire to have the advantage of living
+in an organised community he has to consult not only his
+own fortune but also that of the society and of the ‘neighbours’
+who form the society. He must realise that its
+prosperity is his own prosperity, and that it cannot suffer
+without his own injury. This fundamental law of society
+is so simple and so inevitable that one cannot understand
+how it can be contradicted in theory or in practice; and
+yet that is done to-day and has been done for thousands
+of years.”</p>
+
+<p class='c007'><span class='pageno' id='Page_108'>108</span>The sexual and family instincts may be satisfied in many
+different ways, and this is also the case with the social
+instincts. Onanism and perverted passion may satisfy the
+sexual instinct; celibacy, artificial abortion and infanticide
+exist alongside the love of the wife and the parental cares.
+So also the social instinct of a criminal may be satisfied by
+his association with other criminals. It is well known that
+the most hardened criminals have their own codes, and
+they join faithfulness to their own companions to an
+atrocious attitude towards the rest of the world.</p>
+
+<p class='c007'>It is not enough then merely to give scope to the social
+instincts that we all possess. We have to determine how
+far, and towards which of our fellow creatures, we are to
+exercise such instincts, and it is here that the difficulty arises
+which as yet has not been resolved by religion or rationalism.
+Must our social instincts reach to our relatives near or
+distant, or to our fellow townsmen, or compatriots, or to all
+white men, or to all men, white and black, or to the good
+only, or to the good and bad alike? Perhaps we should
+limit the operation of the instinct to those of our own
+religion, or who share our views of life? The instinctive
+feeling is quite silent on these points, and it is precisely on
+them that the difficulties arise. It is well known that at
+different epochs and in different circumstances very different
+answers have been given to such questions. When religion
+was predominant, a common faith was a bond transcending
+patriotism. Later on, patriotism itself became the dominant
+bond. In recent days, a conception of international solidarity
+began to appear. Thus, for instance, there was recently a
+combination of different nations against China, and nationality
+was forgotten. Some of the European nations banded
+themselves together and even assumed an Asiatic race in
+the union, with the object of punishing a common enemy.
+<span class='pageno' id='Page_109'>109</span>What was the bond that united nations so different? It
+was not religion, for the bond included Catholics and Protestants,
+orthodox Christians and Buddhists. Most probably
+the bond of union was a community of interest, the
+result of similar civilisation and military and political
+organisation.</p>
+
+<p class='c007'>It has been suggested occasionally that the social instinct,
+or human sympathy, for the terms are practically identical,
+may stretch further and further and become so widespread
+that all the members of the human stock will unite and
+act only for the common good. But the problem is complex.
+Sympathy, when pushed too far, may become harmful.
+Nations have taken part in a campaign, impelled by some
+feeling of sympathy, and have brought harm on themselves.
+Sympathy extended to criminals and wicked persons is
+equally harmful. The social instinct itself must be regulated
+for the good of the community which it holds
+together.</p>
+
+<p class='c007'>Ought we to extend our sympathy to all humanity, or to
+limit it to some particular section? Theorists have spoken
+of the solidarity of all humanity, believing it possible to
+extend our sympathy to the races furthest removed from
+us. In countries in which different races are brought in
+contact, very practical difficulties are encountered by the
+theorists. In America and in some other countries, for
+instance, laws have been passed against the Chinese, excluding
+the latter from the consideration granted to other races.
+The negro question also is very difficult in those countries
+in which the black race dwells amongst whites. In Europe
+it has been the custom to condemn the action of civilised
+races in taking their land from natives of primitive type.
+Sutherland, the author of a striking work on the origin and
+development of morality, justifies such arbitrary conduct.
+<span class='pageno' id='Page_110'>110</span>To the question, “Was it right for the whites to take possession
+of the Australian forests of the blacks?” he replied
+in the affirmative. “No doubt,” he said, “there is a moral
+instinct against it, but the action undoubtedly was right.”<a id='r130'></a><a href='#f130' class='c014'><sup>[130]</sup></a>
+In a summary of his conclusions he lays down that moral
+conduct is a compromise between the individual and social
+instincts that so often are opposed. But he has no more
+to say than his predecessors as to the rational basis of the
+compromise.</p>
+
+<p class='c007'>The social instinct has been acquired by mankind too
+recently, and it is still too feeble, to be a trustworthy guide
+in all conduct. To obviate this difficulty, at many different
+times, divine sanction has been evoked to control the relations
+among men. The categorical law has been formulated
+with the same object. Thus by one means or another, some
+kind of social order has been kept up. The efficacy of these
+additional guides is seen clearly on those rare occasions when
+some special combination of circumstances has set people free
+from them. Thus at Moscow, in 1812, before the arrival
+of the French army restored authority, and lately, after
+the eruption in Martinique, the ordinary authority lapsed,
+the anti-social instincts of the people were loose, and a clear
+idea was given of the inherent weakness of the human social
+instinct.</p>
+
+<p class='c007'>I have shown that in man the instinct for choosing food
+and the sexual and social instincts are still so weak that it is
+impossible to trust to them in the absence of other guidance.
+It is as equally necessary to determine what kind of food
+is most suitable for men in different conditions of life, and
+what means are best fitted to satisfy rationally his sexual
+and family instincts. So also it is urgent to determine
+exactly the direction and object of the social instinct. For
+<span class='pageno' id='Page_111'>111</span>the love of our fellow creatures we should seek the best
+ways of making them happy.</p>
+
+<p class='c007'>But what is happiness? Is it the feeling of well-being
+experienced by the individual himself, or is it the judgment
+of others on his sensations? It is notoriously difficult to
+pronounce on the happiness of another. From the outside,
+when a man seems to enjoy health, to have a family and
+comfortable means of subsistence, we are inclined to call him
+happy; but the individual himself may have a very different
+opinion about himself. It is often impossible to rely
+on the judgment of others. On the other hand, the opinion
+of an individual himself on his own condition may be equally
+fallacious. Very often the feeling of well-being is a symptom
+of general paralysis, as may be inferred from the following
+quotation: “The patient is well pleased with himself,
+and delighted with his constitution and circumstances. He
+boasts without ceasing of his robust health, his muscular
+strength, the clearness of his complexion and of his general
+‘fitness.’ His clothing is magnificent and his residence
+palatial. In a more advanced stage of the disease, the
+exaggeration becomes extreme. He believes that he is able
+to blow down the walls with his breath, or that he could
+carry a ton, or drink a hogshead of wine, or that nothing
+could tire him out. Then megalomania begins, and the
+patients believe themselves in possession of titles, of power,
+and wealth. They are members of parliament, noblemen,
+princes, generals, kings, emperors, and popes, or God
+Himself.”<a id='r131'></a><a href='#f131' class='c014'><sup>[131]</sup></a></p>
+
+<p class='c007'>As general paralysis is a result of syphilis, in order to
+make a large number of persons believe themselves thoroughly
+<span class='pageno' id='Page_112'>112</span>happy, it would be necessary only to spread this disease.
+Without lingering on this paradox, I may at least point
+out that the problem of happiness, which is associated
+intimately with social life, is extremely difficult.</p>
+
+<p class='c007'>The social instinct is equally powerless to solve the
+problem of justice in its relation to the general interest of
+humanity. It is plain enough that, in the existing condition
+of human knowledge, we all inflict and undergo
+injustices of different degrees. This misfortune is a consequence
+of the disharmony of human nature.</p>
+
+<p class='c007'>From what I have already said, it must be clear that
+before we can find a rational guide to direct us in the operation
+of our social instinct, we should have to determine
+exactly the nature of true happiness for the individual and
+of true justice. Then only should we be in a position to
+set about making human life as happy as is possible.</p>

+</div>
+
+<p class='c008'>The instinct of self-preservation in animals—Man’s instinctive
+love of life—Indifference to life during childhood—Buddhist
+legend on instinctive self-preservation and
+the fear of death—Fear of death treated in literature—Confessions
+of Tolstoi regarding the fear of death—Other

+
+<p class='c006'>It is not to be wondered at that man’s social instinct exhibits
+so many imperfections and disharmonies, seeing that it is
+still in an unsettled condition, and is a recent acquisition.
+On the other hand, we should expect to find that love of
+life and the instinct of self-preservation had reached a high
+degree of harmony, since these have been in process of
+development throughout the whole animal series that
+culminated in man. Even in the lowest forms of life many
+contrivances exist for purposes of protection. Creatures,
+the bodies of which are merely microscopic drops of protoplasm,
+the living material, may be protected by shells from
+external influences which threaten their destruction. Plants
+protect themselves, sometimes by means of thorns which
+prevent them from being eaten, sometimes by secretions
+<span class='pageno' id='Page_114'>114</span>either merely irritant in character or actually poisonous.
+Among animals the means employed for self-preservation
+are even more numerous. Shields and shells, the secretion
+of fluids exhaling unpleasant odours, or facilitating escape by
+clouding the water, as in the case of the ink of the cuttlefish,
+offensive weapons, strong teeth, and many other characters,
+serve no other purpose than to protect the individual life. The
+exposition of this subject would involve writing a complete
+treatise on the comparative anatomy of plants and animals.</p>
+
+<p class='c007'>Among lower animals the preservation of life is accomplished
+without mental connivance, conscious or unconscious.
+Soon, however, protective instincts begin to appear.
+Simple cases of these are flight at the approach of danger,
+protection by a covering of slimy froth secreted by the
+creatures themselves, or built up from this excreta, or
+from foreign matter. Such facts show that the love of life
+and the instinct of self-preservation are almost universal
+in the living world.</p>
+
+<p class='c007'>All these devices for the avoidance of danger and escape
+from death could have been developed in animals before
+these had any distinct idea as to what death was. We
+know that some animals can distinguish between living and
+dead prey. Some carnivora recognise the smell of dead
+bodies. Those which are accustomed to feed on living
+creatures refuse all others, detecting the difference by the
+absence of movement. As in such cases the idea of death
+is imperfect, it is easy to deceive the creatures by offering
+carcases artificially set in motion, or living prey rendered
+motionless by some means or other. In order to escape
+from enemies so readily imposed upon, many insects when
+alarmed become motionless and feign death; and that may
+be regarded as yet another instance in the category of
+natural means for the protection of individual life.</p>
+
+<p class='c007'><span class='pageno' id='Page_115'>115</span>Moreover, the higher animals, such as mammals, exhibit
+a profound ignorance of death, many of them remaining
+completely undisturbed in the presence of dead companions,
+or even devouring the latter at the risk of contracting a
+fatal disease. Rats, for instance, eat the bodies of rats
+which have died of plague, and while appeasing their hunger
+themselves contract the disease which they transmit to
+other animals, particularly to human beings. Unlike those
+animals, however, which are indifferent to the death of
+their kind, there are others that instinctively shrink at seeing
+the dead bodies of their own species. Horses on passing
+a dead horse show signs of discomfort, and attempt to
+run away. Bullocks when witnessing the slaughter of
+others also exhibit evidences of distress and fear. In spite
+of these examples, however, it is quite certain that animals,
+even those highest in the scale of life, are unconscious of
+the inevitability of death, and of the ultimate fate of all
+living things. This knowledge is a human acquisition.</p>
+
+<p class='c007'>In man, the instinct of self-preservation is well developed.
+Hardly appreciable during infancy, it manifests itself in a
+marked degree in young children. At the sight of a human
+corpse, children become panic-stricken, as though confronted
+by a wild beast or snake.</p>
+
+<p class='c007'>In young adults this instinct of self-preservation, which
+is closely connected with an instinctive fear of death, is
+not fully developed. It often takes some special circumstance
+to awaken it, such as a dangerous illness, an
+accident, or the perils of war. Young people who while in
+good health believe their lives to be in danger, often take it
+to heart so as to make themselves really ill. Relating his
+impressions during the siege of Sebastopol, Tolstoi, who
+at that time was only twenty-six years of age, writes as
+follows: “Notwithstanding the distractions offered by
+<span class='pageno' id='Page_116'>116</span>various and urgent duties, the instinct of self-preservation,
+and the longing to quit this horrible place of death was
+present in the hearts of all. This desire was equally strong
+in all; in those mortally wounded, and in the volunteer
+rushing with all his might into the centre of the fray to
+open a path for the horse of the general, in the general
+himself as he directed and controlled his men. The officer
+of marines, in the middle of a battalion in action, crushed
+so that he could hardly breathe, felt it equally with
+the wounded man carried on a stretcher by four soldiers
+until, further progress being impossible, he had been set
+down just under the Nicolai battery, or the artilleryman
+who had served his gun for sixteen years.” In the normal
+course of life, however, the young do not show an instinctive
+clinging to life in any marked degree. They often risk
+their lives for trifling reasons, and commit all sorts of indiscretions
+hurtful to life or health without a thought of the
+consequences. They may be inspired by the highest
+motives, but they are equally ready to fritter strength away
+in the gratification of the lowest appetites. Youth is the
+age of disinterested sacrifice, but also of indulgence in all
+kinds of excesses, alcoholic, sexual and others. Youths seem
+to think that they will always attach the same value to
+life, and that between death at thirty years of age and
+death at sixty, there is a difference only of time. As their
+love of life is indifferently developed, young people are often
+extremely exacting, the pleasure they enjoy being but
+moderate, whilst the suffering provoked in them by the
+slightest annoyance is intense. They consequently become
+epicureans in the lowest sense of the word, or else abandon
+themselves to exaggerated pessimism.</p>
+
+<p class='c007'>“<span lang="la">Edite, bibite, post mortem nulla voluptas</span>” was the
+motto of German students, greedy for pleasure, and unknowing
+<span class='pageno' id='Page_117'>117</span>that a love of life develops with age in every human
+being. On the other hand, in order to keep the balance
+between joy and sorrow, youth, true to its instincts, undervalues
+the former and exaggerates the latter, thus arriving
+at a pessimistic view of life, and declaring that existence
+is a misfortune in itself. It is significant that Schopenhauer
+published his theory of pessimism at the age of thirty-one.
+His successor, R. Hartmann, when twenty-six years old, proclaimed
+that human existence is an evil which one should
+get rid of at all costs. Optimistic theories, on the other
+hand, have been set forth either by persons advanced in
+years or by persons whom special circumstances have caused
+to appreciate the joy of living. As a counterbalance to the
+pessimism of German philosophers, Duhring formulated a
+theory of optimism in his book “Der <a id='t117'></a>Wert  des Lebens,” but
+was himself blind at the time. Sir John Lubbock published
+some years ago a book entitled “The Pleasures of Life,”
+which opens with the following sentence: “Life is a great
+gift.” His attitude towards life is entirely opposed to that
+of the pessimists, but then he formulated it at the age of
+fifty-three.</p>
+
+<p class='c007'>It has long been recognised that the old attach a higher
+value to life than do the young. J. J. Rousseau, for instance,
+says: “Life becomes dearer to us as its joys pass away.
+The old cling to it more closely than the young.”<a id='r132'></a><a href='#f132' class='c014'><sup>[132]</sup></a></p>
+
+<p class='c007'>This reflection is absolutely correct, and is proved by a
+number of facts. I once knew very intimately a scientific
+man who had passed a very unhappy youth. Being hypersensitive
+to pain, he tried to assuage it by every means in
+his power. Some trifling annoyance sufficing to throw him
+into a state of utter prostration, he was in the habit of
+<span class='pageno' id='Page_118'>118</span>resorting to the aid of narcotics. In order to escape from
+mental anguish he inoculated himself with poisons. By
+the time he had arrived at an advanced age his hypersensitiveness
+gave place to feelings much less acute. He
+ceased to resent the ills of life so bitterly as he did in his
+youth; while he came to appreciate better the positive side
+of life, and even in moments of unhappiness he did not
+contemplate putting an end to his existence.</p>
+
+<p class='c007'>In youth he was pessimistic, and insisted upon the preponderance
+of evil over good. As he became older, his
+attitude towards existence became entirely modified.</p>
+
+<p class='c007'>I do not say, however, that it is necessary to be old in
+order to realise the misfortune of death. “He who pretends
+to face death without fear is a liar,” said J. J. Rousseau.
+“That all men fear to die is the great law dominating the
+thinking world, and without which all living things would
+soon cease to exist. This fear is a natural impulse, and is
+not merely an accident but an important factor in the whole
+order of things.”<a id='r133'></a><a href='#f133' class='c014'><sup>[133]</sup></a></p>
+
+<p class='c007'>One often hears people express their indifference to death,
+but an examination into their real feelings on the subject
+soon shows the true state of affairs. I once happened to be
+present when a lady, already well advanced in years, expressed
+a wish for death, and said that she had no fear of
+it whatever. On acquiring a fuller knowledge of her case,
+I recognised that she was seriously ill, and that she regarded
+death as the only possible termination to her sufferings.
+As soon as she found that recovery was possible, she manifested
+intense delight at the prospect of a prolonged life
+freed from incessant pain.</p>
+
+<p class='c007'>Instinctive love of life, and fear of death, which is only
+a manifestation of the former, are of an importance in the
+<span class='pageno' id='Page_119'>119</span>study of human nature impossible to over-estimate; it is
+therefore necessary to consider a few instances throwing
+light upon the subject. Even the ancients were interested
+in the problem. The subject is perhaps as well dealt
+with in a Buddhist legend as anywhere.<a id='r134'></a><a href='#f134' class='c014'><sup>[134]</sup></a> “The young
+Prince Çakya-Mouni, the founder of the Buddhist faith,
+being desirous of discovering the true meaning of life,
+expressed a wish to leave the world and devote himself to
+a religious life. In order to turn him from his purpose, his
+father built him a magnificent palace, wherein he could
+indulge in every sort of pleasure, and in which he would be
+protected from all sorrow. Under this system he never saw
+old people, nor those who were diseased, nor the dead. In
+spite of being thus strictly guarded, the young prince often
+contrived to escape into the outer world in order to drive
+about. During his first drive, he met a broken-down,
+decrepid old man, with varicose veins, decayed teeth, a
+wrinkled skin, and grey hair, bent double with age like
+the roof of a house, leaning upon a stick; all traces of youth
+had departed from him, only inarticulate words came from
+his throat, his procumbent body resting on the stick,
+and his limbs and every part of them trembling.” Having
+learnt from his coachman that this was an old man, and
+that “in all living creatures age creeps upon youth,” that
+every one came to it and that “there was no way out of
+it,” the prince was so deeply impressed that he said to his
+coachman, “What a misfortune to be a weak foolish person,
+whose intelligence, blinded by the pride of youth, sees nothing
+of old age. Turn round my chariot. I would return. What
+are games and pleasures to me whose body is the future
+dwelling-place of old age?” Another time Çakya-Mouni
+met on the road a man consumed by fever, his body weakened,
+<span class='pageno' id='Page_120'>120</span>his breathing difficult. Informed by his coachman that the
+man was suffering from disease, the young prince exclaimed;
+“Health, then, is a mere dream, and the fear of disease
+takes a terrible form. What wise man, having seen such
+a phase of human existence, could continue to be gay and
+happy?” Shortly after Çakya-Mouni went out for the
+third time, and “saw a dead man placed on a bier covered
+by a pall, surrounded by his relations, all weeping, lamenting,
+wailing, their hair disordered, placing dust upon
+their heads, and beating their breasts.” The violent emotion
+produced by the sight of the dead man caused the
+prince to say to himself: “Woe to youth threatened with
+old age! Woe to health, the prey of every kind of disease!
+Woe to the life of man which lasts but a little while! Woe
+to the attractions of pleasure which seduce the hearts of
+the wise.” These reflections of Çakya-Mouni are the basis
+upon which Buddhism is founded, and that religious philosophy
+is impregnated with pessimistic doctrines relating to
+human life.</p>
+
+<p class='c007'>Modern pessimists hold views resembling Buddhism.
+Schopenhauer from early youth was engrossed by the great
+problems of human life. His mother, in a letter to him<a id='r135'></a><a href='#f135' class='c014'><sup>[135]</sup></a>
+reproached him with “grumbling at the inevitable,” which
+shows that at twenty-seven years of age he had revolted
+against the idea of death. The problem of mortality was
+one of those in which he was most deeply interested, and
+his fear of disease and death was such that he left Berlin at
+the first outbreak of cholera in 1831 (influenced by the death
+of Hegel, who succumbed to the disease), and went to live at
+Frankfort, a town unvisited by the epidemic. He affirms<a id='r136'></a><a href='#f136' class='c014'><sup>[136]</sup></a>
+<span class='pageno' id='Page_121'>121</span>that “the greatest, and generally speaking the worst, misfortune
+that can befall any one is to die, and there is no fear
+equal to the fear of death.” It was the impossibility of escape
+that suggested to him the idea of a pessimistic philosophy.</p>
+
+<p class='c007'>The literatures as well as the philosophies of all periods
+have dealt with the problem of death. Edmond de Goncourt
+tells in his “Journal” how, in conversation with his
+friends, this question was always recurring. The following
+is an account of one of these conversations:<a id='r137'></a><a href='#f137' class='c014'><sup>[137]</sup></a> “Our old
+established dinner of five took place to-day. Flaubert was
+missing, so there were only Tourguéneff, Zola, Daudet, and
+me. The ethical ennui of some of us, the physical sufferings
+of the others, led the conversation to death, which we discussed
+until eleven o’clock, sometimes passing to other
+subjects, but always coming back to the gloomy topic.
+Daudet declared that in his case it was an obsession, <em>a
+poisoning of his life</em>, and that he never moved into a new
+house without looking round for the place where his coffin
+would come to lie. Zola told us that his mother had died
+at Médan, and that, as the staircase proved too narrow,
+the coffin had had to be lowered from a window; he declared
+that he never looked at that window without wondering who
+would be taken out that way next, he or his wife. “Yes,”
+he said, “ever since that day death has always been in the
+background of our thoughts, and very often during the
+night, looking at my sleepless wife, I feel that like me she is
+thinking of it, and we lie quietly without saying aloud
+what is in our minds—for shame, yes, for very shame—<em>Oh!
+it is terrible, that thought—and the terror of it becomes
+visible!</em> There have been nights when I have leapt suddenly
+out of bed, and held myself for a second or two in a state
+of abject terror.”</p>
+
+<p class='c007'><span class='pageno' id='Page_122'>122</span>Jean Finot<a id='r138'></a><a href='#f138' class='c014'><sup>[138]</sup></a> was told in confidence by E. de Goncourt
+that if he could banish the thought of death from his mind
+life would be relieved of an almost intolerable burden. Jean
+Finot also relates that in the course of a memorable evening
+spent with Victor Hugo at the house of the latter, nearly
+all of the distinguished persons who were present, when
+questioned as to their ideas on the subject of death, frankly
+admitted that the thought of it inspired them with fear and
+sadness. Amongst modern authors Count Léon Tolstoi
+has dealt most with the problem of death. In many of his
+works whole pages of memorable reflections on the subject are
+to be found, but the most harrowing and terrible picture he
+ever painted is contained in his “Confessions.”<a id='r139'></a><a href='#f139' class='c014'><sup>[139]</sup></a> The reader
+will pardon my propensity for quoting passages relating to
+death. He will recall the account of the Siege of Sebastopol
+already quoted by me, in which every one was described as
+fearing death when faced by danger; but this fear, as the
+author was a young man of twenty-six, was not wholly
+absorbing.</p>
+
+<p class='c007'>Shortly before he attained his fiftieth year, Tolstoi became
+bitterly tormented by the thought of death. He describes
+the beginning of this mental crisis in the following words:
+“First there came moments of perplexity, of arrest of vital
+force, as though I had lost the power of living and moving;
+I felt utterly lost, and fell into a state of complete dejection.
+This passed away, however, and I continued to live on as
+before. Before long the moments of perplexity became
+more frequent; the arrest of my living energies was always
+manifested by a renewal of the same questions, ‘Why? and
+What comes after?’”<a id='r140'></a><a href='#f140' class='c014'><sup>[140]</sup></a> For some time Tolstoi did not pay
+<span class='pageno' id='Page_123'>123</span>much attention to his mental condition, but by degrees he
+began to analyse it, and reached the following conclusion:
+“The fact is that life is a blind alley. I had lived, worked
+and marched onward, and had arrived at the edge of an
+abyss, and nothing remained to me but to fall into it. And
+yet I could neither stop nor retrace my footsteps, nor shut
+my eyes in order not to see suffering and inevitable death.
+It was a void, a complete annihilation.”<a id='r141'></a><a href='#f141' class='c014'><sup>[141]</sup></a> “In this condition
+I felt that I must cease to live, and, fearing death,
+I had to employ various ruses to prevent myself from
+taking my life.”<a id='r142'></a><a href='#f142' class='c014'><sup>[142]</sup></a> “I could attach no reasonable meaning
+to any action of my life. I was merely astonished to think
+I had failed to realise the position from the beginning. All
+that, I said to myself, must have been patent to all the
+world long ago. If not to-day, then to-morrow, disease
+and death—they are already here—will attack elderly
+persons—me—and there will remain only corruption and
+worms. My deeds, whatever they may be, will be forgotten
+sooner or later, and I shall be no more. Why then take
+pains about anything? How a man can know all this and
+yet go on living amazes me. One can only go on living just
+so long as one is intoxicated with life; once sober, however,
+one cannot fail to see what an idiotic fraud it all is. It is
+also true that there is nothing even amusing or intelligent
+about it; it is simply stupid and cruel and nothing more.”
+Seeing no way out of this, Tolstoi turned his reflections on
+family love: “My family&#160;... I say to myself&#160;... but
+then my family, my wife, and children are also merely human
+beings! They live under the same conditions as I myself.
+They have the choice between living a lie or facing the
+horrible truth. Why then should they live at all? Why
+should I love, cherish, and protect them? In order that
+<span class='pageno' id='Page_124'>124</span>they may experience the same despair, or that they may
+go through life like idiots? Loving them, I cannot conceal
+the truth from them; every step forward in knowledge
+leads to this truth; and the truth is death.”<a id='r143'></a><a href='#f143' class='c014'><sup>[143]</sup></a> To conclude
+this series of quotations, which must have given the
+reader some idea of the love of life and the fear of death,
+I shall give one more example, taken, not from the pen of
+a master but from daily life.<a id='r144'></a><a href='#f144' class='c014'><sup>[144]</sup></a> It refers to the death in the
+Christian community of a “minister of God, who was pious
+as a S. Francis of Assisi, candid as a young girl, of a rigid
+asceticism, and renowned for his charity.” Logically speaking,
+the death of such a man should have been peaceful.
+Had he been a fictitious character, his author would not have
+described his death except in the conventional fashion.
+This is what really occurred, according to the letters of an
+intimate friend of the dying man, who wrote as follows:
+“Our poor friend is fighting death inch by inch in a way
+that is positively tragic. He who was so full of resignation,
+so serene, so perfectly at peace with his own soul, <em>is terrified
+by the approach of death</em>. It is a <em>horrible sight</em>, that moves
+one to tears. We are powerless not only to afford him
+physical relief but to console the terrible anguish which
+assails the clear intellect that clings so desperately to life,
+and which death will claim while fully alive. ‘I could still,’
+he cried, ‘give a course of lectures on theology or political
+economy, and I must die.... It is terrible to be fully conscious....
+How much better it would be if I could not
+think!... And what is it that we ask of God? Eternal
+happiness! It is just as if one of your workpeople came
+and asked you for a thousand francs for a day’s work!’
+You would answer him, ‘What nonsense you talk, you
+<span class='pageno' id='Page_125'>125</span>must be mad, my friend!’ <em>It is hard to die.</em> I confess
+to you, my friend, that this makes one reconsider religion
+and philosophy.... The goodness of God is not what we
+think&#160;... <em>there is a mystery over us</em>.... Is death then
+truly the King of Terrors for those who have led good
+lives?”</p>
+
+<p class='c007'>What is this love of life which makes death so terrible?
+It is a very interesting question, and Tolstoi himself has
+published an essay on “the fear of death.”<a id='r145'></a><a href='#f145' class='c014'><sup>[145]</sup></a></p>
+
+<p class='c007'>He tries to prove that the feeling arises from a false conception
+of life. “Those who fear death,” he says, “fear
+it because it seems an empty darkness, but the darkness
+and emptiness present themselves merely because they have
+a false conception of life.”<a id='r146'></a><a href='#f146' class='c014'><sup>[146]</sup></a> According to Tolstoi man
+should have no greater fear of death than of any of the
+other changes to which it is subjected by life. “No one
+is afraid of falling asleep,” he says, “and yet the phenomena
+of sleep are like those of death—there is the same
+loss of consciousness. Man does not fear sleep, although the
+arrest of consciousness is as complete as in death.”<a id='r147'></a><a href='#f147' class='c014'><sup>[147]</sup></a></p>
+
+<p class='c007'>Tolstoi thinks that the fear of death is a superstition,
+and that it disappears when we see life as it is.<a id='r148'></a><a href='#f148' class='c014'><sup>[148]</sup></a></p>
+
+<p class='c007'>Tokarsky,<a id='r149'></a><a href='#f149' class='c014'><sup>[149]</sup></a> another Russian writer, a few years ago published
+a treatise on the fear of death, and tried to show
+how little reason there was for it. The writer was a physician
+for the insane, and knew himself to be afflicted with
+an incurable and fatal disease. His observations on the
+fear of death were probably based on his own feelings.
+<span class='pageno' id='Page_126'>126</span>Judging from the evidence of a number of persons who had
+been in mortal danger, Tokarsky declared that death had
+no terror, and that it was unnecessary to fear it.</p>
+
+<p class='c007'>Tokarsky’s theory was supported in recent years by
+Finot<a id='r150'></a><a href='#f150' class='c014'><sup>[150]</sup></a> whose arguments in its favour were similar to those
+of his predecessor. He held that man himself created the
+fear of death, and that the prospect of an unknown future
+played a considerable part in it. “Beyond that which we
+see,” says Finot, “there is always something that we cannot
+see, and it is the invisible that we fear.”<a id='r151'></a><a href='#f151' class='c014'><sup>[151]</sup></a> The idea that
+death is generally attended by pain seems to Finot quite
+erroneous, and he comes to the conclusion that “our ignorances
+and prejudices are responsible for the creation of this
+superstition, so terrible to contemplate, so far removed
+from the truth.”<a id='r152'></a><a href='#f152' class='c014'><sup>[152]</sup></a> Instances which have occurred of people
+threatened with death and suddenly restored to life, give
+proofs, according to Finot, that death, far from being painful,
+is attended by pleasant sensations. With regard to this,
+Heim, a Swiss savant, says that tourists who have had
+serious falls while mountaineering, and have been so near to
+death that they experienced all the premonitory symptoms,
+felt above all a sensation of ecstasy.</p>
+
+<p class='c007'>It cannot be denied that some forms of death are pleasant,
+but it is no less certain that in many other cases, and these
+too the majority—the sensation of approaching death is,
+on the contrary, extremely painful. This question, however,
+is not necessarily connected with the fear of death
+that may come to those who are not yet about to die. But
+it is precisely the latter mode of fear that is so important
+a factor in human life. Men who are dying of starvation
+do not feel painfully hungry at the moment of death. The
+<span class='pageno' id='Page_127'>127</span>actual pain of hunger lasts only for a limited period,
+probably, in the case of man, only about twenty hours,
+after which it is succeeded by a condition of lassitude and
+general weakness, which however is different from painful
+hunger. The fear of death is similar, for in certain cases it
+does not last up to the end of life. The pain of thirst, on
+the other hand, is much more persistent, lasting up to
+the end.</p>
+
+<p class='c007'>Finot discussed the instinctiveness of the fear of death.
+“The question,” he wrote, “is important. For if the fear
+be instinctive, it is independent of our will and not to be
+controlled by reason. It would then break out in every
+case at the approach of death. Now the evidence of many
+persons who have no more than escaped mortal danger is
+clearly against the view.”<a id='r153'></a><a href='#f153' class='c014'><sup>[153]</sup></a> Hunger is certainly instinctive,
+and yet is not always felt when the body is exhausted by
+want of food or menaced by death from starvation.</p>
+
+<p class='c007'>Closer investigation leaves no doubt but that the fear of
+death is truly an instinct. In some of the higher animals
+it exhibits itself in the same fashion as other instincts. The
+intimate friend, whom I have already mentioned, was for
+years in constant expectation of death, and faced its approach
+with perfect calmness. Believing that he had played his part
+in life to the best of his power, not only did he think it quite
+natural that he should cease to live, but he regarded the
+possibility of a decrepid and painful old age with the greatest
+possible repugnance. In his case, neither reason nor desire
+led to a fear of death. When, however, it was definitely
+diagnosed that he suffered from a disease which might prove
+fatal, there was aroused in him a certain sensation which
+must have been the fear of death. Analysis of Tolstoi’s
+statements in his “Confessions” makes it clear that his
+<span class='pageno' id='Page_128'>128</span>sensations on reflecting that he too would cease to be, and
+that there would be left only corruption and worms, were
+no other than the instinctive fear of death, a fear that his
+reason was powerless to control. To follow Tolstoi in
+telling any one that the fear of death is a form of superstition
+which must be subdued by the intelligence, is no better than
+to attempt to console a woman about to undergo ovariotomy
+by telling her that as in future she will be unable to bear
+children she ought to subdue her sexual instincts. She will
+find out that her desire is not under control of the will but
+is a pure instinct.</p>
+
+<p class='c007'>The fear of death has long been recognised as an instinct.
+Schopenhauer,<a id='r154'></a><a href='#f154' class='c014'><sup>[154]</sup></a> for instance, interpreted it in that way.
+According to him, “from the point of view of intelligence
+there is no ground for fearing death. Reason, which is the
+outcome of knowledge, does not present death to us as an evil.
+It is certainly not the rational, conscious part of ourselves
+which fears death; the <em>fuga mortis</em> which pervades all living
+beings is an emanation of the blind will.” This “blind
+will” is no other than a pure instinct which is independent
+of our rational will.</p>
+
+<p class='c007'>I need not pursue the subject, but I may recall that Lord
+Byron came to the conclusion that the fear of death is an
+instinctive manifestation of the soul. In “Cain” he
+expressed this view sufficiently clearly:—</p>
+
+<div class='lg-container-b c022'>
+  <div class='linegroup'>
+    <div class='group'>
+      <div class='line in26'>I live,</div>
+      <div class='line'>But live to die; and living, see nothing</div>
+      <div class='line'>To make death hateful, save an <em>innate clinging</em>,</div>
+      <div class='line'>A loathsome, and yet all <em>invincible</em></div>
+      <div class='line'><em>Instinct of life</em>, which I abhor, as I</div>
+      <div class='line'>Despise myself, yet cannot overcome—</div>
+      <div class='line'>And so I live.</div>
+    </div>
+  </div>
+</div>
+
+<p class='c021'><span class='pageno' id='Page_129'>129</span>Later on in the same poem Byron makes Cain say of his
+father Adam:—</p>
+
+<div class='lg-container-b c022'>
+  <div class='linegroup'>
+    <div class='group'>
+      <div class='line in20'>Ere he plucked</div>
+      <div class='line'>The knowledge, he was ignorant of death.</div>
+      <div class='line'>Alas, I scarcely now know what it is;</div>
+      <div class='line'>And yet I fear it, fear I know not what.</div>
+    </div>
+  </div>
+</div>
+
+<p class='c007'>It is then indubitable that among the instincts of man
+there is one which loves life and fears death. This instinct
+develops slowly and progressively with age. In that respect
+it is astonishingly different from other instincts. When
+hunger or thirst or sexual desire is gratified a sensation of
+satisfaction is experienced, and this readily passes into satiety
+or even indifference. The mood lasts for a certain time,
+and then the instinctive needs reawaken. The instinct of
+life, however, behaves very differently. In most human
+beings it develops slowly and becomes stronger and stronger
+as the years pass by. In childhood and early youth we are
+very anxious to “grow up,” but when we are adult we have
+no desire to grow old. We are greatly disturbed by the
+appearance of wrinkles and grey hair. Instead of being
+glad to have finished a great part of our mortal career, we
+feel sad at being nearer the inevitable end. Old age, as
+it usually presents itself, is marked by ugly features, and
+often by repugnant or even horrible characters. Little
+children are usually terrified by the appearance of very old
+persons, and it is a familiar nursery threat to send for an
+old man.</p>
+
+<p class='c007'>The murder of the aged is a custom widespread amongst
+the lower races. The natives of Fiji bury their old men
+alive, on the pretext that they have become utterly useless.
+The custom is in existence throughout Melanesia, and occurs
+in New Caledonia and in most of the adjacent Polynesian
+islands. Old age is universally despised in that part of the
+<span class='pageno' id='Page_130'>130</span>world. The natives of Australia respect old people so long
+as they retain their activity, but once they become unable
+to take care of themselves they are abandoned. Often
+they are killed and eaten, and this custom is favoured by
+their religious beliefs.<a id='r155'></a><a href='#f155' class='c014'><sup>[155]</sup></a> The ancient inhabitants of Germany,
+according to the investigations of Grimm, “killed the old
+and the sick, and often buried them alive.”</p>
+
+<p class='c007'>The modern civilised world has certainly made considerable
+progress. The old are no longer killed; they are tolerated,
+and accorded liberty to commit suicide. In many countries
+work is often refused to the old on the plea that they are
+not strong enough for it, and at the same time they are
+refused admission to almshouses on the pretext that they
+are not yet old enough. Dealing with the question of the
+average life and of the normal life, Paul Bert<a id='r156'></a><a href='#f156' class='c014'><sup>[156]</sup></a> expressed
+himself with regard to the aged as follows: “They deserve
+congratulations, care and consideration, <em>but the prolongation
+of their lives does not demand any special solicitude from
+society</em>.”</p>
+
+<p class='c007'>However, in spite of the characters of old age which make
+it horrible and useless, and at best no more than to be tolerated,
+and in spite of the physical and intellectual weakness that
+accompany it, the instinctive love of life is preserved in the
+aged in its strongest form. To make quite certain about this
+I have visited almshouses for the aged, and it was easy to
+see that all the inmates hoped that their days might be prolonged.
+In a Home occupied by fairly well-educated
+persons, I discovered that one and all felt as if they were
+<span class='pageno' id='Page_131'>131</span>continually being threatened by death, as if they were
+convicts awaiting the day of execution. At the Salpêtrière,
+where there are a number of very old women,
+septuagenarians are regarded almost as young girls. The
+great ambition of women of eighty is to live to one hundred,
+and the desire to live is almost universal.</p>
+
+<p class='c007'>This seems a contradiction of another fact demonstrated
+by statistics, that age increases the frequency of suicide.
+It is certain that more old men commit suicide than young
+men, but on careful inquiry into the statistics of the subject,
+it becomes evident that the chief incentive to suicide
+does not lie in the cessation of the will to live, but in the
+difficulties experienced by old people of earning a living,
+and in the frequent presence of disease in the aged.
+Deprived of the means of existence, refused the shelter of
+charitable institutions, old men are apt to fall back upon
+a rope or the fumes of charcoal. Statistics relating to the
+suicide of the aged show that the greatest number of victims
+belong to the poorer classes. The suicide of rich old men
+is generally prompted by the presence of incurable disease.
+There is, however, need for much wider inquiry into the
+subject. It would be interesting, for instance, to obtain
+more detailed information regarding the motives which
+urge the old to put an end to themselves. In recent times
+the suicide of Max von Pettenkofer aroused public attention.
+After a distinguished scientific career, he resigned his post
+of Professor at the University of Munich at the age of seventy-six.
+He went to live a little way outside the town on a property
+where he devoted himself to gardening and other
+country pursuits. Although a sufferer from diabetes, his
+intellect remained unimpaired, but he became a prey to
+extreme melancholy, owing to the death of some friends to
+whom he was greatly attached. Moreover, during the
+<span class='pageno' id='Page_132'>132</span>latter part of his life he suffered from a septic affection of
+the neck. This disease, not fatal in itself, was the indirect
+cause of Pettenkofer’s death, which occurred by suicide at
+the age of eighty-three. The <em>post-mortem</em> examination<a id='r157'></a><a href='#f157' class='c014'><sup>[157]</sup></a>
+showed a fairly well preserved organic system, healthy,
+with the exception of chronic inflammation of the membranes
+of the brain and atheroma of the cerebral arteries.
+The circumstances relating to this particular case of suicide
+are unusually well known, and yet there are many obscure
+points about it which are of the highest importance. The
+chronic meningitis from which the aged scientist suffered
+conclusively precluded the theory that the motives which
+led him to commit suicide were prompted by the phenomena
+of normal life. On the other hand, instances are not wanting
+of old men of good education and refined surroundings who
+cling tenaciously to life, even at a much more advanced
+age than the Munich professor.</p>
+
+<p class='c007'>The instinctive love of life resembles the sexual instinct
+in a great many women. Just as the love of life goes on
+increasing when the best of life is past, sexual pleasure
+is often unfelt by women until their beauty is already
+faded.</p>
+
+<p class='c007'>Another character common to the love of life and the
+sexual instinct is that they both persist throughout old
+age, although they can no longer be satisfied.</p>
+
+<p class='c007'>Edmond de Goncourt relates in his diary that at his
+réunions of literary celebrities (Zola, Daudet, and Tourgéneff),
+the conversation turned most frequently upon
+the subjects of love, life and women. “Death or love,
+strangely enough,” says Edmond de Goncourt, “are always
+what we talk about after dinner.”<a id='r158'></a><a href='#f158' class='c014'><sup>[158]</sup></a> Old age was even then
+<span class='pageno' id='Page_133'>133</span>knocking at the doors of the distinguished writers mentioned,
+and so it is quite natural that their interest should
+have been wholly absorbed by the two instincts which
+exhibit such enigmatic and paradoxical tenacity.</p>
+
+<p class='c007'>We saw in the preceding chapter how disharmonious is
+the sexual instinct which often only develops at, and nearly
+always persists until, a period of life when its normal and
+regular functional activity is no longer possible. We saw,
+too, the ill resulting from this disharmony in the reproductive
+apparatus. The ill, however, although serious, only
+amounts in that case to an inconvenience which can be
+endured.</p>
+
+<p class='c007'>Far worse is the disharmony of the instinctive love of
+life which manifests itself when death is felt to be near at
+hand. It is then incomprehensible and particularly terrible,
+and humanity, from time immemorial, has sought the key
+to the tragic puzzle, and tried by all the means in its power
+to unravel the mystery. The religions of all times have
+been concerned with the problem. “Religion,” says
+Guyau,<a id='r159'></a><a href='#f159' class='c014'><sup>[159]</sup></a> “consists for the most part of meditation upon
+death. If we had not to die there would probably
+be still more superstitions among men, but there would
+probably be no systematised superstitions nor religions.”
+Philosophy also has tried to solve the question of death.
+Some ancient philosophers held the opinion that philosophy
+is only a meditation upon death. Socrates and Cicero<a id='r160'></a><a href='#f160' class='c014'><sup>[160]</sup></a>
+have well said that “the life of a philosopher is a continual
+meditation upon death.” In our own day Schopenhauer
+developed the same theory. “Death,” he said,<a id='r161'></a><a href='#f161' class='c014'><sup>[161]</sup></a> “is the
+real inspiring genius of philosophy.... Without death it
+<span class='pageno' id='Page_134'>134</span>is doubtful if philosophy would exist at all. It is therefore
+quite natural that a special essay on Death should preface
+the last, the most serious, and the most important of my
+books.”</p>
+
+<p class='c007'>Judging from the facts set forth in the last three chapters,
+there can be no doubt but that the human constitution,
+although in many ways perfect and sublime, exhibits
+numerous and serious disharmonies, which are the
+source of all our troubles. Not being so well adapted to
+the conditions of life as orchids are, for example, in the
+matter of their fertilisation by the mediation of insects,
+or the burrowing wasps for the protection of their young,
+humanity resembles rather those insects the instinct of
+which guides them towards the flame which burns their
+wings.</p>
+
+<p class='c007'>Even at a time when humanity had attained no definite
+knowledge of itself, a vague suspicion prevailed as to the
+existence of disharmonies, and an effort was made to remedy
+the evil. The following chapters will show what man has
+done with a view to remedying the natural disharmonies
+of his constitution.</p>

+
+<p class='c006'>Humanity did not await the discovery by science of the
+existence of disharmonies before trying to find remedies for
+them. The will to live, to preserve health, to satisfy the
+instincts and to make them act in unison, have driven
+mankind, in the very earliest days of reflection, to invent
+remedies for the imperfection of the human constitution.</p>
+
+<p class='c007'>I have shown that, even in the case of animals, the instinct
+as to choice of food does not save them from certain harmful
+substances. Man himself has for long recognised that this
+instinct of his is no safe guide, and has tried to discover
+surer methods of distinguishing between substances that are
+<span class='pageno' id='Page_138'>138</span>useful as foods and substances that may cause disease or
+death. The best wisdom of primitive man must have been
+given to the observation of the effects of substances which
+had been eaten, and to a consequent framing of dietary
+rules.</p>
+
+<p class='c007'>The reproductive functions, in the same way, must have
+attracted the notice of man in very early times, as he must
+have found the harm that came from a blind following
+of instinctive desire.</p>
+
+<p class='c007'>Above all other reasons, man must have been impelled
+by his instinctive love of life and fear of death to find some
+way out of his dangerous situation. To preserve his life,
+man must have sought wise choice of food and control of
+sexuality.</p>
+
+<p class='c007'>Since the dawn of intelligence, man has tried to judge the
+unknown from the analogies given by what he knows best,
+that is to say, by his own self. Thus he came to attribute
+to everything around him qualities like his own qualities,
+and motives like his own motives. He came to think not
+only that all living beings were possessed of will and intelligence,
+but that inanimate things conducted themselves like
+human beings.</p>
+
+<p class='c007'>Such a primitive idea is the basis of what Tylor has called
+“Animism,” the foundation of the philosophy and religion
+of savage and civilised man alike. When a man was seen
+to die, it was plain that he did not entirely disappear, but
+merely became transformed into a new condition. The dead
+body was not alive as we are, but, none the less, it was
+alive in a fashion of its own. This was the answer to the
+desire for the preservation of life, to the fear of death, that
+is to say, of total extinction. It is practically identical with
+faith in immortality and a future life.</p>
+
+<p class='c007'>The animistic conception is almost world wide. It is
+<span class='pageno' id='Page_139'>139</span>plain that it afforded the most efficacious palliative for
+minds revolting against the inevitability of death, and that
+it harmonised with our intense will to live. “Such child-like
+ignoring of death,” wrote Tylor,<a id='r162'></a><a href='#f162' class='c014'><sup>[162]</sup></a> “such child-like make-believe,
+that the dead can still do as heretofore, may well
+have led the savage to bury with his kinsman the weapons,
+clothes, and ornaments that he used in life, to try to feed
+the corpse, to put a cigar in the mouth of the skull before
+its final burial, to lay playthings in the infant’s grave.
+But one thought beyond would carry this dim blind fancy
+into the range of logical reasoning. Granted that the man
+is dead, and his soul gone out of him, then the way to provide
+that departed soul with food or clothes or weapons is
+to bury or burn them with the body.”</p>
+
+<p class='c007'>It is needless to recapitulate the various animistic customs
+which were in vogue among primitive peoples, and which
+have left marked traces amongst nearly if not all civilised
+races. The details may be found in the works of
+several authors, notably Tylor, Lubbock, and Waitz-Gerland.<a id='r163'></a><a href='#f163' class='c014'><sup>[163]</sup></a>
+I shall mention only a few, choosing those that
+seem most plain. The Turanians of Eastern Asia bury
+with their dead all sorts of implements, such as axes and
+flints, and food, such as meat and butter, believing that the
+departed will have need of these during the long voyage
+in the land of the spirits. A Tasmanian, on being asked
+why spears were buried with the dead, replied, as if the
+answer were self-evident, “Of course for the use in combat
+of him who has fallen asleep.” The Greenlanders place
+bows and other weapons in the tombs of their men, and
+<span class='pageno' id='Page_140'>140</span>knives, needles, and other instruments for sewing are buried
+with their women, in the full belief that such objects will
+be useful in the other world. In the Congo region, the
+curious custom exists of leaving a hole in the grave over
+the mouth of the dead body, and once a month passing
+into this hole meat and drink.</p>
+
+<p class='c007'>Many races are not content to place merely inanimate
+objects in the graves. The Caribbeans, believing that
+the human spirit after death is carried to the kingdom of
+dead souls, sacrifice slaves on the tombs of their chiefs,
+in order that the latter may be attended in the next world.
+With the same object they bury dogs and weapons. The
+negroes of the Gold Coast, at the funeral of a great man,
+kill women and slaves that he may be provided for in the
+next world. Moreover, they bury with him his finest
+apparel, his gilded fetishes, and corals and pearls, so that
+the dead man may continue to make use of them.</p>
+
+<p class='c007'>Tylor states that such animistic conceptions occur amongst
+all savages without exception. According to Herbert
+Spencer, if we take groups of the human race, such as tribes,
+societies, and nations, we find abundant evidence that all,
+or nearly all, have a belief, vague or clear, in the resurrection
+of a double of the dead man. It has been suggested that
+the origin of this widespread belief is the image of the
+departed that comes to us in dreams. These images are
+taken as real visits of the dead.</p>
+
+<p class='c007'>In civilised races there are numerous relics of the old
+beliefs. The Spaniards set bread and wine on the graves
+of their relatives on the anniversaries of their deaths.
+The Bulgarians hold a feast of the dead on Palm Sunday.
+They eat and drink well, and then leave the remains of
+the banquet on the graves of their relatives that these may
+consume them in the night.</p>
+
+<p class='c007'><span class='pageno' id='Page_141'>141</span>Saint-Foix<a id='r164'></a><a href='#f164' class='c014'><sup>[164]</sup></a> relates that when Bertrand du Guesclin was
+buried at St. Denis, in 1389, several horses were sacrificed.
+The Bishop of Auxerre first blessed them, laying his hands
+on their heads, and then they were killed. At Treves, in
+1781, at the burial of General Frederic Casimir, his horse,
+according to the custom of the Teutonic Order, was led in
+front of the bier, and when the General had been laid in
+the tomb, the horse was killed and buried with him.<a id='r165'></a><a href='#f165' class='c014'><sup>[165]</sup></a></p>
+
+<p class='c007'>Although the sacrifice of men and animals is no longer
+made by civilised peoples at burials, many funeral customs
+have an obviously animistic origin. In Russia, for instance,
+rice is placed alongside the corpse, and pine branches are
+strewed along the way to be traversed by the procession.
+The wreaths of “immortelles,” used so largely at funerals
+by the modern French, have an extremely ancient origin.
+They were employed by the Romans, and probably their
+use implied a conception of a future life in a region where
+plants and flowers grew.</p>
+
+<p class='c007'>The belief in life after death, so widespread in the world,
+has been the foundation of all religions. I cannot follow
+this question here as closely as it deserves. To investigate
+it elaborately would take more space than this volume
+affords, and more knowledge than I possess. However,
+it is important to my argument to insist that, among races
+that have inhabited very different parts of the earth, that
+have had very different manners and have passed through
+different stages of civilisation, the conviction has been strong
+that death is not the end of all, but only a door leading from
+one kind of existence to another. Because of the high importance
+of the existence of this conviction, however, I must
+<span class='pageno' id='Page_142'>142</span>discuss some of the criticisms that have been made as to its
+universality.</p>
+
+<p class='c007'>It has been asserted repeatedly that the idea of a future
+life was not a part of the Jewish religion, as formulated
+in the Bible. Haeckel has recently repeated a common
+opinion that belief in the immortality of the soul was absent
+from the oldest and purest form of the Jewish religion.
+“There is not to be found,” he said, “either in the Pentateuch
+or in those more ancient parts of the Old Testament
+which were written before the Babylonian captivity, any
+idea of the persistence of the human soul.” This is true
+only within limits. No doubt the books of Moses contain
+no reference to a future life nor to heaven and hell in the
+sense of modern creeds, but it is no less true that the ancient
+Jews shared with other races the conception of a survival
+after death. “Like almost all primitive nations,” wrote
+Renan,<a id='r166'></a><a href='#f166' class='c014'><sup>[166]</sup></a> “the Hebrews believed in a kind of double personality,
+in a shadow pale and thin which, after death,
+descended underground and passed a sad and colourless
+existence in the sombre halls of the dead. The dead
+dwelt there, without feeling, or knowledge, or memory,
+in a world without light, abandoned by God. At the most
+the old Hebrews hoped to obtain for themselves a quiet
+resting-place, a pleasant couch for the time when they would
+be with the dead. It comforted them to picture themselves
+as lying amongst their ancestors in quiet communion.”</p>
+
+<p class='c007'>Ancestor-worship, which is associated closely with the
+idea of a future life, appears repeatedly in the Pentateuch.
+Jacob, when he felt death coming upon him, called his son
+Joseph and said unto him, “Bury me not, I pray thee, in
+Egypt; but I will lie with my fathers, and thou shalt carry
+me out of Egypt, and bury me in their burying-place.”
+<span class='pageno' id='Page_143'>143</span>According to Chantepie de la Saussaye,<a id='r167'></a><a href='#f167' class='c014'><sup>[167]</sup></a> “we are coming
+to recognise more and more how strongly the children of
+Israel, and in fact all other peoples, were tinged with
+animism and ancestor-worship.”</p>
+
+<p class='c007'>It is very remarkable how the idea of a future life, which
+was vague in the early days of Israel, grew more and more
+clear. Ezekiel (sixth century <span class='fss'>B.C.</span>), when he had “seen the
+visions of God,” prophesied of things to come, and declared
+that God would breathe life into the dry bones of the dead.
+The Book of Daniel (second century <span class='fss'>B.C.</span>) expressed the same
+idea in a stronger fashion: “And many of them that
+sleep in the dust of the earth shall awake, some to everlasting
+life and some to shame and everlasting contempt”
+(Daniel xii. 2). “It is plain,” said Renan,<a id='r168'></a><a href='#f168' class='c014'><sup>[168]</sup></a> after quoting
+these words, “that Israel had now reached the last stage in
+the secular development of her ideas, and had reached the
+conception of the kingdom of God, as synonymous with the
+future world and the resurrection. As the conception of
+a soul distinct from the body was foreign to her, she could
+not conceive of a future life apart from resurrection of
+the body.”</p>
+
+<p class='c007'>Still later, in the Talmud, the conception of a future life
+is clothed with details. Paradise is depicted as a region
+filled with sweet odours, while hell is an unclean place,
+thick with mire and smoke. According to the Talmud, in
+the life beyond the grave, “there is neither eating nor drinking;
+the good sit there with crowns on their heads and see
+God in bliss.”<a id='r169'></a><a href='#f169' class='c014'><sup>[169]</sup></a></p>
+
+<p class='c007'>At the date of the Cabalistic philosophy, the Jews had
+<span class='pageno' id='Page_144'>144</span>embraced the doctrine of transmigration of souls, and had
+come to believe that the spirit of Adam had entered David
+and would pass on to the Messiah. Some human souls
+passed into the bodies of animals, into the leaves of trees,
+or even into stones.</p>
+
+<p class='c007'>It is plain that the idea of a future life was a part of
+the Jewish religion.</p>
+
+<p class='c007'>It has been said, also, that the idea of a future life was
+absent from the religions of the Chinese. Büchner,<a id='r170'></a><a href='#f170' class='c014'><sup>[170]</sup></a> for
+instance, who came to be almost the official representative of
+the materialism of the second half of last century, asserts that
+“Buddhism, that famous religion, the most widespread and
+one of the most ancient, which counts among its followers
+nearly a third of the inhabitants of the earth, ignores completely
+the immortality of the soul.” Haeckel, also, in
+the “Riddle of the Universe,” a volume that sums up the
+materialism of the end of the last century, makes a similar
+statement. “The higher oriental religions include no belief
+whatever in the immortality of the soul; it is not found
+in Buddhism, the religion that dominates 30 per cent.
+of the entire human race; it is not found in the ancient
+popular religion of the Chinese, nor in the reformed religion
+of Confucius which succeeded it.”<a id='r171'></a><a href='#f171' class='c014'><sup>[171]</sup></a></p>
+
+<p class='c007'>This question demands a somewhat closer investigation.
+It has been thoroughly proved that the basis of the ancient
+religion of the Chinese was no more than an extreme development
+of ancestor-worship. Every important event in family
+affairs was accomplished “in the presence of the ancestors.”
+It was a bond with relatives beyond the grave. As in
+other cases of animism and ancestor-worship, meats were
+offered to the dead, and objects were buried with them
+<span class='pageno' id='Page_145'>145</span>to be of service to them. According to A. Réville,<a id='r172'></a><a href='#f172' class='c014'><sup>[172]</sup></a> the
+Chinese as a whole “fully recognised the conception of
+personal survival after death; if there were no other reason
+for stating this, it would be enough to point out that offerings
+of real food would be incomprehensible, if made to persons
+supposed to be non-existent or reduced to complete unconsciousness.”
+As they offer to the dead, food and clothing
+and precious things, it is plain that the Chinese think of
+life beyond the grave as not very different from this life.
+“The dead maintain their interest in the affairs and persons
+and food that was familiar to them.”</p>
+
+<p class='c007'>As the idea of immortality became developed further,
+the Chinese modified their customs. Instead of offering to
+the dead material objects, as is still done by many peoples,
+they came to substitute emblems. “Houses and clothing
+and food imitated in paper, and dolls of paper and straw
+to represent slaves, are burned, so that the spiritual forms
+of these objects may be offered to the spirit they wish to
+honour.”<a id='r173'></a><a href='#f173' class='c014'><sup>[173]</sup></a></p>
+
+<p class='c007'>One of the chief motives of ancestor-worship is fear lest
+the dead, if neglected, may visit their wrath on the living
+by sending plagues and pestilence upon them.<a id='r174'></a><a href='#f174' class='c014'><sup>[174]</sup></a></p>
+
+<p class='c007'>The worship of the dead had laid hold of the Chinese so
+firmly that even Confucius, notwithstanding his intelligence
+and scepticism, paid it a large tribute. “Confucius
+the philosopher,” said Réville, “regarded it as a duty to
+offer to his ancestors the gifts of food that princes had sent
+to him desiring to honour him.”<a id='r175'></a><a href='#f175' class='c014'><sup>[175]</sup></a></p>
+
+<p class='c007'><span class='pageno' id='Page_146'>146</span>Confucius and his followers were reticent and ambiguous
+in their references to a future life, but that attitude did
+not prevent them from “observing the customs and ceremonies
+as carefully as if they had had a confident faith in
+the immortality of the soul.”<a id='r176'></a><a href='#f176' class='c014'><sup>[176]</sup></a> Although Lao-tseu himself
+believed neither in heaven nor hell, and professed the most
+rationalistic views, his disciples none the less accepted the
+doctrine of immortality, and even came to believe in rewards
+and punishments after death.</p>
+
+<p class='c007'>The followers of Lao-tseu, the Taoists, devoted themselves
+specially to the problem of immortality. They made
+efforts to discover an elixir that would be capable of prolonging
+earthly life to eternity. “One of the chief claims
+of Taoism,” wrote Réville, “was the possession of a specific
+against death. It was true that they admitted this to be
+not only very difficult to obtain, but still more difficult to
+employ. However, if certain rules were observed strictly
+they were at least confident of great prolongation of life.
+It was only the very few Taoists who had reached perfection
+who could hope to pass into the better world without
+being subjected to the pains of death.”<a id='r177'></a><a href='#f177' class='c014'><sup>[177]</sup></a> “And so some of
+the masters of Taoism, such, for instance, as Chang-Tao-Ling,
+ascended to heaven without dying, by climbing a
+lofty peak and vanishing into the skies.”<a id='r178'></a><a href='#f178' class='c014'><sup>[178]</sup></a></p>
+
+<p class='c007'>The ordinary Taoists accepted fully the idea of immortality.
+They “taught the doctrine of purgatory for those who
+were not evil. To arrive at this, Lao-tseu simply expanded
+and applied to mankind generally an idea that was already
+familiar to him, the conception of the transmigration of
+one soul through several successive bodies. By means of
+<span class='pageno' id='Page_147'>147</span>such expiatory transformations, a man who had not reached
+it directly through the holiness of his life, could attain the
+immortality of genii and the blessed.”<a id='r179'></a><a href='#f179' class='c014'><sup>[179]</sup></a></p>
+
+<p class='c007'>It was believed for long that the Taoists, following the
+teaching of their master, did not recognise a hell. But
+this opinion has had to be abandoned, because the “Taoist
+clergy have provided, in the temples dedicated to the tutelary
+deities of their cities, paintings illustrating the torments prepared
+for the guilty by the ten courts of justice that sit in
+the depths of an ocean hidden in the interior of the earth.”<a id='r180'></a><a href='#f180' class='c014'><sup>[180]</sup></a></p>
+
+<p class='c007'>Clearly then, many Chinese, both Taoists and followers
+of Confucius, believe in the existence of a world beyond the
+grave. However, the denial of immortality has been
+ascribed to Buddhists in particular.</p>
+
+<p class='c007'>Buddha accepted the Brahmanist doctrine of transmigration
+of the soul. This has been established clearly on
+the evidence of several documents of admitted authenticity.
+Orthodox Buddhism is somewhat vague on the immortality
+of the soul. Buddha himself avoided making a decisive
+statement on this matter. In such circumstances “those
+who were terrified at annihilation, and who could not give
+up the hope of eternal happiness, interpreted the silence of
+Buddha according to their own desire, and inferred that he
+did not forbid them to hope.”<a id='r181'></a><a href='#f181' class='c014'><sup>[181]</sup></a></p>
+
+<p class='c007'>There are many instances of the evasions of Buddhist
+teachers when they were pressed with this disturbing question.
+Pasénadi, the king, once met Khémâ, the nun, a
+disciple of Buddha, renowned for her wisdom. The king
+put to her the following question: “Does the Perfect One
+(Buddha) exist after death?” “The Sublime One, O
+<span class='pageno' id='Page_148'>148</span>great king, has not revealed to us the existence of paradise
+beyond the grave.” “Then the Perfect One exists no longer
+now that he is dead, O reverend lady?” “Neither, O
+king, has the Sublime One revealed that He who is perfect
+does not exist now that He is dead.” “Am I to believe, then,
+O reverend lady, that the Perfect One still lives, although
+He is dead, and at the same time does not live? Am I to
+believe, O wise lady, that the Perfect One being dead,
+neither exists nor does not exist?”<a id='r182'></a><a href='#f182' class='c014'><sup>[182]</sup></a></p>
+
+<p class='c007'>Take again the mode in which Soumirmitá,<a id='r183'></a><a href='#f183' class='c014'><sup>[183]</sup></a> “the son of
+a god, and surrounded and preceded by a crowd of gods,”
+worshipped Bouddha (Tathâgata): “Thou art the physician,
+skilful to save, and who givest the gift of life everlasting.”</p>
+
+<p class='c007'>The Buddhists, as they were not given clear doctrines on
+this subject, very naturally followed their inclinations by
+accepting the idea of life beyond the grave. And certainly
+Buddhism does not teach annihilation of the body after
+death, although this has been lightly taken for granted.
+On the contrary, it is so persuaded of survival after death
+as being the rule, that it grants only to rare and elect souls
+the privilege of at length laying down the burden of continuous
+life.<a id='r184'></a><a href='#f184' class='c014'><sup>[184]</sup></a></p>
+
+<p class='c007'>The Chinese Buddhists retained the fundamental conceptions
+of the ancient religion of their land and continued to
+worship their ancestors and to seek the readiest path to
+immortality. They soon came to transform Nirvâna into
+paradise, and to inculcate in the Chinese race the doctrine
+of future rewards and punishments. “The Buddhist monasteries
+in China for the most part possessed a set of little
+<span class='pageno' id='Page_149'>149</span>rooms, in which there were depicted, in vivid colours,
+crowded scenes from the eighteen hells of tribulation
+and lamentation. For there exist under the earth
+eight hells filled with the torments of fire, and ten with
+the equally terrible horrors of ice.”<a id='r185'></a><a href='#f185' class='c014'><sup>[185]</sup></a></p>
+
+<p class='c007'>The paradise of the Chinese Buddhists, or Ni-pan (Land of
+the Pure), is a region abounding in “gold and silver, and
+precious stones. Rivers of crystal run on golden sands
+covered with splendid lotus-flowers and traversed by
+delightful paths. Lovely music is always to be heard.
+Three times a day a shower of blossoms falls. There are
+to be seen there gorgeous birds, pheasants, and parrots,
+and many others; and these, every quarter of an hour, in
+a choir of melodious voices, trill out the beauties of religion
+and recall to their hearers the Buddha, Dharma, and Sungha.
+These are some of the wonders prepared for those who are
+born again after death. Into that land neither sin nor
+any evil enters.”<a id='r186'></a><a href='#f186' class='c014'><sup>[186]</sup></a></p>
+
+<p class='c007'>I need no longer accumulate details to show the falseness
+of the view that a third of humanity profess materialism
+to the exclusion of any belief in survival after death. On
+the other hand, it is quite certain that the vast majority
+of mankind is convinced that death puts no definite term
+to existence, and that this life is no more than a passing
+stage leading to a life to come. However, although many
+simple races believe that the future life is merely a continuation
+of this life, the more subtle-minded races present the
+future life as filled with delights for the good and with
+torments for the wicked.</p>
+
+<p class='c007'>Such an idea of the next world, which is very generally
+accepted, is probably the basis of religions. From it have
+come the conceptions of supreme beings and divinities
+<span class='pageno' id='Page_150'>150</span>Many facts go to show that the primitive gods were no other
+than the relatives and ancestors of the living, now dead,
+yet living in another world and ruling the affairs of this
+world. Wicked ancestors became transformed into evil
+spirits, while good ancestors became mild and benevolent
+deities.</p>
+
+<p class='c007'>Very many peoples offer prayers to their ancestors and
+treat them as gods. The Kaffirs pray and sacrifice to their
+dead relatives, believing that the spirits of the dead haunt
+their late dwelling-places, and, according to their characters,
+help or torment their descendants. As they are able to
+cause good or evil after death, these play the part of gods.
+But, as Lubbock points out (“Origin of Civilisation”),
+it must be remembered that the god of a savage is only
+a being like unto himself, although probably rather more
+powerful, and I shall show that there are many intermediate
+stages between true gods and mere dead parents whose malice
+is to be feared, or whose kindness is to be supplicated.</p>
+
+<p class='c007'>The North American Indians<a id='r187'></a><a href='#f187' class='c014'><sup>[187]</sup></a> pray to the spirits of
+their forefathers for good weather or luck in hunting, and
+fancy when an Indian falls into the fire that the ancestral
+spirits pushed him in to punish neglect of the customary
+gifts, while the natives of Louisiana are said to have even
+gone so far as to build temples for dead men. In Polynesia
+“at Tanna, the gods are spirits of departed ancestors, aged
+chiefs becoming deities after death, presiding over the growth
+of yams and fruit-trees, and receiving from the islanders
+prayer and offerings of first fruits.”<a id='r188'></a><a href='#f188' class='c014'><sup>[188]</sup></a> In the Malay Islands
+“the souls of deceased ancestors are looked to for prosperity
+in life and help in distress.” In Africa ancestor-worship
+is well developed. The Zulu warriors, “aided by
+<span class='pageno' id='Page_151'>151</span>the amatongo,’ the spirits of their ancestors, conquer in
+the battle. Even the little children and old women, of
+small account in life, become at death spirits having much
+power, the infants for kindness, the crones for malice. But
+it is especially the head of each family who receives the
+worship of his kin.”<a id='r189'></a><a href='#f189' class='c014'><sup>[189]</sup></a> The Zulu adores his father, when
+he is a chief, above all others, and is convinced that a father
+remembering his love for his children, will not forget them
+when he is dead. “The Zulu follows up the doctrine of
+divine ancestors till he reaches a first ancestor of man and
+creator of the world, the primeval Unkulunkulu.”<a id='r190'></a><a href='#f190' class='c014'><sup>[190]</sup></a></p>
+
+<p class='c007'>So great is the number of instances that it is too difficult
+to choose from them. The fundamental idea is always
+identical, although details and accessories vary, as one passes
+from the hardly idealised relatives of negro tribes and goes
+progressively to the “Father Almighty, Maker of heaven
+and earth” of the Nicene Creed.</p>
+
+<p class='c007'>The conception of a future life in the form of immortality
+or some kindred state, associated with the conception of
+many gods or of one God, has been developed to satisfy the
+craving for life and to combat the fear of death, that is to
+say, to defeat the greatest contradiction in the constitution
+of man. I must now inquire how far the different religions
+have been successful in this object.</p>
+
+<p class='c007'>Many primitive races have absolute faith in the tenets
+of their religion, and believe in the promise of life beyond
+the grave as in a certain fact. Thus the aborigines of the
+Fiji islands are convinced that they will be born again, in
+another world, in the exact condition in which they leave
+this life; and so they wish to die before being afflicted
+with any infirmity. As it is very difficult to reach old age
+without being the victim of some illness or infirmity, when
+<span class='pageno' id='Page_152'>152</span>a man feels the approach of age, he tells his children that
+the time has come for him to die. If he himself fails to
+give this notice, the children undertake the duty. A family
+council is called, the day is appointed, and the grave made
+ready. The old man is allowed to choose between being
+strangled and being buried alive. The following instance
+will show the strength of a belief in life to come. Hunt,
+an English traveller, quoted by Lubbock, received a visit
+from a young native of Fiji, whose purpose was to give an
+invitation to the funeral of his mother which was to take
+place next day. Mr. Hunt accepted the invitation and
+joined the procession, but as he was surprised to see no dead
+body, inquired about it from the son. The son pointed out
+his mother, walking in the procession and as gay and animated
+as any of the others. Mr. Hunt stated his surprise,
+and asked why he had been deceived by being told that the
+mother was dead, when she was plainly as much alive and
+as well as any one else. He received the reply that the
+death festival was about to be celebrated; that presently
+they would bury her; that she was old, and that his brother
+and he, thinking that she had lived long enough, and should
+be put to death, had obtained her cheerful consent.</p>
+
+<p class='c007'>This case is far from being solitary, because many villages
+have been described as containing no inhabitants of a greater
+age than forty years, all those older having been buried. It
+is not difficult to understand that death should have no
+terrors for persons possessed of a faith as strong as this.
+The American Indian, according to Lubbock, has very little
+fear of death. He does not fear transference to a realm
+in which, as he has been told all his life, there is no sorrow
+and abundance of joy.</p>
+
+<p class='c007'>I know a case of a young girl of the Catholic faith who
+believed so firmly in the joys of Paradise that, when stricken
+<span class='pageno' id='Page_153'>153</span>with a mortal illness, she awaited death with a great impatience.
+Before she died, she cried out that “already she
+could see the beautiful flowers and hear the sweet music of
+the birds that fill heaven.”</p>
+
+<p class='c007'>But it is rare to find faith so strong in such a case. More
+often faith is not strong enough to subdue the fear of death,
+and in proof of this I may recall the instance of the clergyman
+already given.<a id='r191'></a><a href='#f191' class='c014'><sup>[191]</sup></a> Stricken with an incurable disease,
+he, in spite of his religion, underwent extreme agony,
+and could not reconcile himself to the idea of death. The
+fear of death showed itself so strongly in this case that I
+have chosen it as a characteristic instance of the feeling.</p>
+
+<p class='c007'>It is only with fanatics and simple or primitive persons
+that blind faith can subdue this instinctive fear. For this
+reason, since the most ancient times, religions have sought
+out something more than the promise of paradise to mitigate
+this chief disharmony of our nature. In this connection
+the doctrines of Buddha are those most interesting. Here
+I shall not deal with that modified and transformed Buddhism,
+in which, as I have already shown, there was a return
+to the doctrine of future life, with its hell of torments and
+heaven filled with delights.</p>
+
+<p class='c007'>Buddha made no reference to the great blot on human
+life. His doctrine, in its original form, was extremely
+pessimistic. Take, for instance, some of his sayings on this
+subject: “Miserable in truth is this world, in which there
+is beginning, birth, growing old, death, disappearance and
+renewal. But we know not how to escape from this world,
+full of horror though it be. Alas, because of old age, illness,
+death, and their like, we know not who shall put an end
+to this world, which is so full of horror. To all who are,
+there comes old age, and illness, and death, and their like.”<a id='r192'></a><a href='#f192' class='c014'><sup>[192]</sup></a></p>
+
+<p class='c007'><span class='pageno' id='Page_154'>154</span>When the Buddha came upon the sorrows of the world,
+as I have already described (p. <a href='#Page_119'>119</a>), he reflected as follows:
+“Woe upon youth, threatened by old age! Woe upon
+health, which so many maladies destroy! Woe upon the
+life of man, which lasts but a little space! Woe on the
+temptations of the flesh, which lure the heart of the wise!
+Would that there were neither old age nor illness, nor
+death and the pains of death, which come from the five
+elements of life (Skandhas)! Would that there were neither
+old age nor illness nor death, which are for ever bound up
+together! Nevertheless, when I return again I shall consider
+deliverance.”<a id='r193'></a><a href='#f193' class='c014'><sup>[193]</sup></a></p>
+
+<p class='c007'>Having pondered for many days on these problems,
+Buddha thought that he had discovered the only solution,
+and taught men resignation. When a man was young he
+would ask of his father: “Lord, would that old age would
+never come upon me, and that I should keep for ever the
+warm colour of my youth; that I should be always filled
+with health, and that no disease should come near me; that
+my life should be prolonged for ever, and that death should
+pass me by! Such an one later on must learn to give up
+these longings.”<a id='r194'></a><a href='#f194' class='c014'><sup>[194]</sup></a></p>
+
+<p class='c007'>In his famous “Sermon at Benares,” Buddha gave in
+brief the outlines of his doctrines in the following words:
+“Hear, oh monks! the holy truth of the springs of sorrow!
+Sorrow is born of lust of life, that drags us from incarnation
+to incarnation, and of pleasure and desire, which seek their
+fulfilment hither and thither; the lust of pleasure, the lust
+of life, the lust of power. Hear, oh monks! the holy truth
+of the conquest of sorrow; it is the killing of this lust by
+the utter abandonment of desire, the giving up of all desire,
+<span class='pageno' id='Page_155'>155</span>the forgetting of all desire, the freeing of the body of all
+desire, until there is no place left for desire.”<a id='r195'></a><a href='#f195' class='c014'><sup>[195]</sup></a></p>
+
+<p class='c007'>In such a spirit of resignation, Buddha became himself
+a monk, and lived according to the strict rules of the pure
+life that he himself had laid down (“the belief pure, the will
+pure, the language pure, the deeds pure, the means of livelihood
+pure, the study pure, the attention pure, the meditation
+pure”). However, he did not find many kindred
+souls to follow the same precepts. Buddhism soon moved
+away from these original tenets, and became a religious
+doctrine of the ordinary kind.</p>
+
+<p class='c007'>We are inclined to associate with Buddhism the doctrine
+of Nirvâna, as if the latter were the goal to which human
+life should be directed. Many philosophers, and the pessimists
+chief among them, naturally with Schopenhauer
+at their head, have adopted Nirvâna as the goal of mankind,
+as they see the world. However, the word Nirvâna has
+had many interpretations put upon it, the which is less
+surprising as Sanscrit scholars differ. I do not intend to
+join in the discussion, as I myself am not acquainted with
+Sanscrit, upon which the argument must be founded. However,
+I cannot pass it by without comment on the pretext
+that it has not yet been settled definitely by specialists,
+as it is the case that many thinkers regard Nirvâna as the
+goal of human existence.</p>
+
+<p class='c007'>For long Nirvâna was represented as a sort of blank, in
+which there was no display of any mental operations. Max
+Müller,<a id='r196'></a><a href='#f196' class='c014'><sup>[196]</sup></a> the celebrated Oxford professor, opposed this
+interpretation on the ground that, according to him, in
+“all passages of Buddhistic origin in which Nirvâna occurs
+there is nothing to betoken annihilation. Most of these
+passages, if not all of them, would be quite unintelligible
+<span class='pageno' id='Page_156'>156</span>if we were to replace in them the word Nirvâna by the word
+annihilation.”</p>
+
+<p class='c007'>Many other specialists share this view, and cannot agree
+that the goal of human life was to be annihilation. Rhys
+Davids, for instance, thinks that Nirvâna is to be interpreted
+as a tranquillity of the soul, possible of achievement in this
+life, and that the word is best translated by the term “sanctity.”
+According to him, Nirvâna does not mean extinction
+or annihilation, but rather freedom from the great
+passions, such as envy and hate. Pfungst<a id='r197'></a><a href='#f197' class='c014'><sup>[197]</sup></a> agrees with
+Max Müller; he is convinced that the first adepts of Buddha
+could not have conceived of Nirvâna as extinction. Dahlmann<a id='r198'></a><a href='#f198' class='c014'><sup>[198]</sup></a>
+on the other hand, tries to prove that Nirvâna
+in its primitive signification implied the abolition of the
+will to live, and really corresponded to annihilation.</p>
+
+<p class='c007'>I must add, however, that Nirvâna did not occupy a
+place in Buddhism so important as has been ascribed to
+it by several commentators. In many of the Buddhist
+authorities mention of Nirvâna is only accidental. In the
+“Lalita Vistara,” for instance, the word occurs very seldom,
+and then only in unimportant connections. However, the
+latter document contains a good deal that serves to explain
+the conception of Nirvâna.</p>
+
+<p class='c007'>When the young Buddha, still very exacting, asked his
+father to obtain for him perpetual youth, health, life everlasting,
+and freedom from death, he added the following
+words: “Lord, if you cannot give me these four gifts, at
+least bring it about that after this life I shall have no more
+metempsychoses.”<a id='r199'></a><a href='#f199' class='c014'><sup>[199]</sup></a></p>
+
+<p class='c007'>As I have already stated, Buddhism had embraced the
+<span class='pageno' id='Page_157'>157</span>Brahmanistic doctrine of transmigration of souls. According
+to the legend, before his birth as a prince, the Buddha
+had passed hundreds of earlier existences. His soul had
+been the soul not only of fifty-eight kings, but of eighteen
+monkeys, four horses, four snakes, three lizards, two fish,
+and of other creatures.<a id='r200'></a><a href='#f200' class='c014'><sup>[200]</sup></a> Such continual transferences of the
+soul to so many different animals was a source of perplexity
+and sorrow to believers. It was natural that a great thinker
+like Buddha should have conceived the desire of sparing
+himself and his faithful followers so many transmigrations.
+He thought of these rebirths as a great evil, from which a
+pure life might set one free.</p>
+
+<p class='c007'>In the poetical language of the Hindoo Buddhists, metempsychosis
+was compared to the ocean; the waves that change
+from moment to moment were the continual rebirths; our
+temporary body was the foam of the crests of the waves,
+while Nirvâna was the opposite shore. He who reaches
+Nirvâna would never again plunge into the great sea of
+Sangsâra. In a passage quoted by Rhys Davids, and
+ascribed to Kâma Sutta, it is stated expressly that “the
+sea is an image of the Sangsâra or transmigrations, while
+Nirvâna is an island upon it. Once the shores have been
+reached, a soul will no longer be plunged in the waves of
+the ocean, and will be freed from the successive births of
+metempsychosis.”</p>
+
+<p class='c007'>In other words, to avoid being tormented after death by
+perpetual rebirths, some of which may be humiliating, it
+is necessary to live a pure life and so to secure repose or
+Nirvâna. Nirvâna is by no means the cessation of all consciousness,
+but merely the end of transmigrations. From
+such a point of view, it is possible to interpret all, or at least
+nearly all, the passages in which Nirvâna is spoken of.</p>
+
+<p class='c007'><span class='pageno' id='Page_158'>158</span>When he was old and full of disease and afflicted with
+grievous pain, Buddha, being at the point of death, thought
+of his disciples and called them to him and said: “It is not
+meet that I should enter Nirvâna without having spoken
+with those who have cared for me, without speaking to the
+community of disciples. By the force of my will I shall
+subdue this disease and hold the life within me.” Some
+time afterwards, the reverend Ananda went to Buddha
+and spoke to him, saying amongst other words as follows:
+“The Sublime One will surely not enter into Nirvâna ere
+he has made known unto the community of disciples his
+wishes regarding them.” “Growing more and more feeble,
+the spirit of Buddha passed from ecstacy to ecstacy without
+ceasing, and knew every delight; then he entered into
+Nirvâna. And the earth trembled, and thunder rolled
+across the skies.”<a id='r201'></a><a href='#f201' class='c014'><sup>[201]</sup></a></p>
+
+<p class='c007'>It is clear that in this passage Nirvâna was associated
+with death. But it was with the death of a saint who had
+lived a pure life. Metempsychosis would not be inflicted
+on him, and he would enjoy repose. It is probable that
+the term Nirvâna later on came to be applied to the state
+of mind of a saint who, by living the pure life, would avoid
+transmigration after death.</p>
+
+<p class='c007'>As the importance of Nirvâna lies in its contrast with
+metempsychosis, it is easy to see why the precise state of
+mind involved in it has not been described exactly. However,
+a survey of the Buddhistic writings makes it plain
+that at least Nirvâna was not associated with annihilation.
+In this respect Max Müller’s verdict must be taken as correct.</p>
+
+<p class='c007'>Buddha’s attempt to remedy the ills of human life, then,
+lay in a complete renunciation of all the joys and pleasures
+of life, and in perfect resignation. The mere fact that
+<span class='pageno' id='Page_159'>159</span>primitive Buddhism did not persist, but rapidly passed into
+an ordinary religion, is sufficient proof that Buddha did not
+achieve his purpose. It was the promise of a life to come
+that attracted so many men and spread Buddhism over
+so large a part of the earth. However, this faith has been
+able to maintain itself only in certain strata of society to
+which the rationalistic conception of the mental processes
+has not penetrated. Since the awakening of the scientific
+spirit in Europe, it has been recognised that the promise
+of a future life has no basis of fact to support it. The modern
+study of the functions of the mind has shown beyond all
+question that these are dependent on the functions of the
+body, in particular of those of the central nervous system. A
+slight lowering of the rate of the circulation of the blood, a
+fleeting anæmia of the brain, at once arrests consciousness,
+that is to say, the fundamental sensation of the individual
+mental life. Anæsthetics, used in doses so small that they
+do not influence certain parts of the nervous system, as, for
+instance, those that control the heart and lungs, completely
+abolish consciousness. Persons who are put under chloroform
+for surgical purposes fall into a state of absolute unconsciousness.
+Sometimes, after undergoing painful sensations,
+especially sensations of oppression, the patients imagine
+themselves to be in rapid motion, and in a few moments
+have the sensation of falling into an immense gulf, after
+which comes nothingness, the annihilation of sensations and
+of consciousness. In other cases, patients, without any
+sensation of catastrophe, lose all idea of reality, and every
+psychic and sensorial function is abolished. Such states
+are very closely similar to death, which indeed is the result,
+in certain rare instances, of the ordinary process of being
+chloroformed.</p>
+
+<p class='c007'>Neither the narcosis produced by chloroform nor that
+<span class='pageno' id='Page_160'>160</span>produced by any other form of anæsthetic, affords any
+particle of ground for the view that there is consciousness
+in any form apart from the body. The action of morphine
+sometimes brings about a strange current of happiness and
+an apparent weightlessness of the body; but here again
+there is no suspicion given as to the existence of any mental
+phenomena apart from the body.</p>
+
+<p class='c007'>Consciousness of personality is of supreme interest
+from the point of view of personal immortality, and this
+mental phenomenon develops only slowly and progressively
+in an infant. This fact, again, like the facts of narcosis,
+shows the dependence of consciousness on the action of the
+bodily organs. Just as our consciousness comes out of
+nothing in the first months, or years, of our life, so it will
+pass into nothing at the end of our life.</p>
+
+<p class='c007'>Mental disease confirms this conclusion, and it, too, gives
+no ground for the belief in a survival of the mind after
+death.</p>
+
+<p class='c007'>Certain internal sensibilities in the depths of our organism
+survive our personal consciousness. When the heart has
+ceased to beat, and when the anæmic brain is certainly
+incapable of personal consciousness, some portions of the
+body may still retain vitality. The muscular fibres are still
+able to contract when they are stimulated, and the white
+corpuscles of the blood can still exhibit their specific movements.
+It is certain, moreover, that these white corpuscles
+possess a specific sensibility, and, by a sort of sense of taste,
+respond to the kind of environment that surrounds them.
+Our consciousness, however, is absolutely out of touch with
+the sensations of these globules, which, however, none the
+less are part of our organism. It happens, therefore, that
+in certain diseases, the white corpuscles, stimulated by
+the presence of particular substances, perform extensive
+<span class='pageno' id='Page_161'>161</span>movements of migration within our bodies. Such migration
+is quite outside the sphere of consciousness. The corpuscles,
+directed by their sensibility, are in constant pursuit of
+microbes that have entered the body, and yet these actions,
+too, are not made known to our consciousness. In the same
+fashion, the thousands of active spermatozoa in the male
+organs and the ova in the female possess specific sensibility.
+These reproductive elements contain the germ of
+individual consciousness, but it is not until they have
+developed into the new generation that it is possible to
+impute to them individual consciousness, and the organism
+that shelters them has no idea of what it harbours. The
+sensibility of the white corpuscles and of the many other
+cells composing our body, although certainly a reality, has
+no part in the absolutely special sensation that we call individual
+consciousness, and which is all we think of in wishing
+to escape death.</p>
+
+<p class='c007'>The idea of a future life is supported by not a single fact,
+while there is much evidence against it. The phenomenon
+of intercommunication across a distance, sometimes called
+telepathy, may be actual, but affords no support to the
+conception of the existence of souls apart from bodies. It
+may be that emanations are given off by certain organs,
+and that these are capable of being appreciated by the organs
+of another body at a distance; but, even if such were the
+case, we should have to deal simply with other bodily
+functions. Moreover, the supposed phenomena that fall
+within this category are so rare, so difficult to observe, and
+so obscure, that no certain argument for the continuance
+of existence after death can be deduced from them.</p>
+
+<p class='c007'>It is easy to see why the advance of knowledge has
+diminished the number of believers in the persistence of
+consciousness after death, and that complete annihilation
+<span class='pageno' id='Page_162'>162</span>at death is the conception accepted by the vast majority
+of enlightened persons.</p>
+
+<p class='c007'>Apart from their chief function of consoling men for the
+inevitability of death, religions have concerned themselves
+with some of the results of other disharmonies of the human
+constitution. From time immemorial they have claimed
+the direction of diet, the control of the reproductive functions
+and the prevention or cure of all kinds of disease.</p>
+
+<p class='c007'>The dietary regulations given by the religions are familiar.
+Even at the present day, the cookery of many races is
+regulated by their religion. The Jewish diet, notably, is
+regulated by the Mosaic law, down to the most minute
+detail. For instance, it was forbidden to eat the blood
+of animals. Moses commanded: “Notwithstanding, thou
+mayest kill and eat flesh in all thy gates, whatsoever thy
+soul lusteth after, according to the blessing of the Lord
+thy God, which he hath given thee; the unclean and the
+clean may eat thereof, as of the roebuck, and as of the
+hart. Only ye shall not eat the blood; ye shall pour it
+on the earth as water.”<a id='r202'></a><a href='#f202' class='c014'><sup>[202]</sup></a> Later on: “Only be sure
+that thou eat not the blood; for the blood is the life;
+and thou mayest not eat the life with the flesh.”<a id='r203'></a><a href='#f203' class='c014'><sup>[203]</sup></a> “Thou
+shalt not eat it, that it may go well with thee, and
+with thy children after thee, when thou shalt do that which
+is right in the sight of the Lord.”<a id='r204'></a><a href='#f204' class='c014'><sup>[204]</sup></a> The Books of Moses
+also contain receipts for the cooking of certain meats.
+“Eat not of it raw, nor sodden at all with water, but roast
+with fire, his head with his legs, and with the purtenance
+thereof.”<a id='r205'></a><a href='#f205' class='c014'><sup>[205]</sup></a></p>
+
+<p class='c007'>It has been suggested that these rules were founded on
+ideas of hygiene in consonance with the results of modern
+<span class='pageno' id='Page_163'>163</span>science. Some of them, it is true, such as the prohibition
+of uncooked or partially cooked meat, are confirmed by our
+modern knowledge. But the greater number of the Mosaic
+rules, as, for instance, the prohibition of the consumption
+as food of blood or the flesh of pigs or hares and so forth,
+are in direct opposition to a modern knowledge of hygienic
+diet. Religious cookery has no more than a historical
+interest.</p>
+
+<p class='c007'>The religions have been greatly occupied with the functions
+of the reproductive organs. Most of the founders of
+the great faiths have paid a keen attention to the disharmonies
+of this side of our constitution. They became persuaded
+of the merit of abstention, which they practised
+themselves and preached to others. Buddha, after devoting
+his youth to all the pleasures and not being satisfied, passed
+to absolute asceticism. He and his adepts formed an order
+of monkhood, on which an absolute celibacy was imposed.
+If a member of the order had intercourse with a woman, he
+was considered to be as guilty as a murderer or a thief. In
+the Buddhist rules framed even for laymen, “sexual intercourse
+outside marriage was forbidden, on the ground that
+it was degrading.”<a id='r206'></a><a href='#f206' class='c014'><sup>[206]</sup></a></p>
+
+<p class='c007'>The views of the Christian religion on sexual matters are
+well known. The leaders of Christianity abstained from
+sexual intercourse and recommended their conduct to others.
+St. Paul more than once affirmed his own continence.
+“For I would that all men were even as I myself; but
+every man hath his proper gift of God, one after this manner,
+and another after that. I say therefore, to the unmarried
+and widows, It is good for them if they abide even as I; but
+if they cannot contain, let them marry, for it is better to
+marry than to burn.”<a id='r207'></a><a href='#f207' class='c014'><sup>[207]</sup></a></p>
+
+<p class='c007'><span class='pageno' id='Page_164'>164</span>The religions of savage races are equally concerned with
+the reproductive functions. There are many extremely
+strange facts known concerning this matter, and among
+such I may mention that the Sandwich Islanders have a
+deity who presides at abortions. This god is made in the
+form of an elongated wooden instrument, and is known as
+“Kapo.” The upper part of the deity is shaped into a
+grotesque head, while the lower portion terminates in a
+point and serves to induce abortion by entering the uterus
+and rupturing the fœtal membranes.<a id='r208'></a><a href='#f208' class='c014'><sup>[208]</sup></a></p>
+
+<p class='c007'>Many other idols are used by savages as protections
+against disease. Ploss-Bartels,<a id='r209'></a><a href='#f209' class='c014'><sup>[209]</sup></a> in his treatise on “Medicine
+among Primitive Races,” has described a large collection of
+talismans of this kind. The ruling idea in the manufacture
+of these is that diseases are due to the presence of evil spirits,
+who are to be scared away as soon as possible. The Goldi
+of Siberia construct straw or wooden figures of men and
+animals to absorb the spirits of diseases. The Guilaks
+make wooden human figures, on the breasts of which are
+fashioned images of toads. These talismans are used as
+remedies for diseases of the chest and stomach.</p>
+
+<p class='c007'>In higher forms of religion there remain abundant traces
+of such notions. Even Martin Luther declared that disease
+was supernatural in origin. “Behold a matter on which
+there is no room for doubt,” he stated, “and that is that
+the plague, fevers, and other diseases are the work of the
+devil.” A number of religious ceremonies were specified
+as the best remedies for diseases.</p>
+
+<p class='c007'>The plague has left many deep marks on human history,
+and it is natural that a malady so terrible should have
+attracted serious attention. It was usually attributed to
+<span class='pageno' id='Page_165'>165</span>divine wrath, which was to be appeased by purification and
+sacrifice. Human beings were slain on altars to appease
+the wrath of God and to lessen the mortality from plague.</p>
+
+<p class='c007'>Such religious customs have disappeared almost completely
+with the advancing culture of man, but traces of
+them survive and become apparent on occasions. Quite
+recently, when the King of England, Edward VII., was
+afflicted with an abdominal suppuration, he was given the
+assistance of the most highly skilled modern surgery, but
+at the same time special services were held in the churches
+to aid the cure of the royal invalid.</p>
+
+<p class='c007'>Every one has now come to regard such events as mere
+relics of old customs without intrinsic importance. Hygiene
+in the kitchen and the prevention of disease are no longer
+under the control of religion, but are regulated on scientific
+knowledge obtained by the experimental method. I need
+pay no further attention to these matters. However, religion
+is still occupied with the problem of death. The
+solutions which as yet it has offered cannot be regarded as
+satisfactory. A future life has no single argument to support
+it, and the non-existence of life after death is in consonance
+with the whole range of human knowledge. On the other
+hand, resignation as preached by Buddha will fail to satisfy
+humanity, which has a longing for life, and is overcome by
+the thought of the inevitability of death.</p>
+
+<p class='c007'>It was to be expected that in such a state of affairs philosophers
+would have sought an issue from the dilemma.
+Certainly many philosophical theories have been propounded
+to explain life and death. As the subject is of extreme
+importance I shall reserve a chapter for it.</p>

+  <h3 class='c001'>CHAPTER VIII<br> <span class='c012'>ATTEMPTS IN SYSTEMS OF PHILOSOPHY TO REMEDY THE ILLS ARISING FROM THE DISHARMONIES OF THE HUMAN CONSTITUTION</span></h3>
+</div>
+
+<p class='c008'>Some philosophical systems are in intimate union with
+religions—Ideas of ancient philosophers on the immortality
+of the soul—The teaching of Plato—The scepticism of
+Aristotle—The Stoics—Cicero, Seneca, Marcus Aurelius—Modern
+philosophical systems—Pessimism and its origin—Lord
+Byron—Theories of Schopenhauer and Hartmann—Mailaender’s
+philosophy of deliverance—Criticisms of
+pessimism—Max Nordau—Ideas of modern thinkers on
+death</p>
+
+<p class='c006'>Systems of philosophy are closely attached to religious
+doctrine. Buddhism, for instance, originated in a philosophic
+theory which acquired a religious character in the
+hands of the followers of Buddha. Similarly, many systems
+of philosophy are merely religious dogmas which it has
+been attempted to support by rational argument apart
+from supernatural revelation.</p>
+
+<p class='c007'>The idea of life beyond the grave has long since furnished
+one of the principal bases of various philosophic doctrines,
+the ultimate object of which was to solve the problem of
+death. Ancient philosophy is full of such. Plato describes
+the tragic death of his master Socrates, and in connection
+with it expresses very clearly his ideas upon death. He puts
+these words in the mouth of Socrates in the “Phaedo”: “Far
+from being depressed by the death of a friend, I felt, on the
+<span class='pageno' id='Page_167'>167</span>contrary, that he was to be envied; as I witnessed his
+attitude, and listened to his words, and noticed the courage
+with which he faced death, I became convinced that he did
+not quit this life without some divine support that drew
+him towards another world in which he would find the most
+perfect happiness man could wish.”</p>
+
+<p class='c007'>Plato attributes to Socrates a very definite view as to
+future retribution: “In truth,” said Socrates, “if I did not
+expect to find in another life gods at once good and wise,
+and men better than those of this life, it would be foolish of
+me not to be disturbed by the approach of death. But I
+know that I look to finding myself among just men. I do
+not fear to die, because I am confident that something still
+remains after this life, and that, according to the old belief,
+the good will be treated better than the bad.”</p>
+
+<p class='c007'>As such views were not derived from a body of revealed
+truth, it was necessary to support them by reasoning.
+Plato therefore went on to try to convince us of the immortality
+of the soul by speculative hypotheses. He recalled
+the Pythagorean doctrine of metempsychosis, and suggested
+that the souls who had abandoned themselves to
+injustice, tyranny, and plunder would pass into the bodies of
+wolves and hawks and falcons, for souls of that nature
+could not go elsewhere; while the souls of those who had
+practised the social and civic virtues known as temperance
+or justice, would inhabit the bodies of peaceful and gentle
+creatures such as bees and ants, or would even enter other
+human bodies and again become good men.</p>
+
+<p class='c007'>Plato referred also to the law of contrasts in support
+of his theory. “As the most strong often springs from
+the feeblest, or the most swift from the slow, so life gives
+rise to death, and from death life springs.” “From that
+which is dead,” said Socrates, “is born all that lives and
+<span class='pageno' id='Page_168'>168</span>has life. And so our souls after death pass to the infernal
+regions.” “As we must grant that the dead are born from the
+living as much as the living from the dead, it is plain that
+the souls of dead men exist somewhere, whence they may
+return to life.”</p>
+
+<p class='c007'>By such arguments Plato tried to prove the immortality
+of the soul, the fundamental basis of his philosophy, and
+put them in the mouth of his master Socrates on his deathbed.
+In the dialogue he tried to refute all kinds of objections.
+But, in spite of the assurance with which he formulated
+his doctrine, there may be seen underlying the
+argument a note of doubt, and it is just this that distinguishes
+philosophy from religion.</p>
+
+<p class='c007'>It is evident that the whole of Plato’s system was the
+result of an effort to solve the problem of death. Again
+and again he said that the true philosopher lived only to
+be ready to die; that being so, he declared it to be childish
+for men at the last to shrink from what they had so long
+been making ready for. It was himself that Plato wished
+to convince of a future life. “I do not seek,” he said, “to
+persuade all those who are here of the truth of what I say,
+although to do so would greatly please me; what I aim at
+is to convince myself. Behold me, dear friend, in pursuit
+of an argument that, as you see, interests me deeply; if
+what I say turns out to be true, it is good to have believed
+it, and if there be nothing after death, at least I have gained
+this, that while I am still with you, I am not borne down
+with grief.”</p>
+
+<p class='c007'>The doubt which was only latent in Plato was much
+more active in some other ancient philosophers. Aristotle<a id='r210'></a><a href='#f210' class='c014'><sup>[210]</sup></a>
+at one time admitted that part of the soul was immortal,
+<span class='pageno' id='Page_169'>169</span>but that the other part was mortal. The two parts came
+together at the beginning of a life and separated at its
+end. Later on, however, Aristotle abandoned this theory
+of the immortality of the personal consciousness, and argued
+strongly against the Platonic theory of the immortality of
+the soul, although, however, he still believed in the indestructibility
+of the “rational spirit,” an immortal principle.</p>
+
+<p class='c007'>The Stoics still further developed such a conception.
+They held that besides the individual soul there was a
+universal soul, a presiding influence in which all others had
+their being.</p>
+
+<p class='c007'>Cicero, again, discussing old age and death, tried to establish
+belief in a future life. “I am convinced,” said Cicero
+to Scipio and Laelius, “that your illustrious fathers, who
+were so dear to me, are still full of life, and of the only life
+worthy of the name; for the body is, as it were, our prison-house,
+within which we must accomplish the tasks laid on us
+by necessity. When I think of the activity of the human
+spirit, its vast memory, its prevision, its store of art and
+knowledge, and experience, I am convinced in the depths
+of my being that an existence with such qualities cannot
+be mortal. The soul is continually active, and its activity
+comes not to it from without; the soul is a self-supporting
+activity, and cannot come to an end. Moreover, as the
+soul is a simple substance, unalloyed by any mixture of
+materials, it can neither be divided nor made to perish.”
+By such arguments Cicero sought to prove the immortality
+of the soul. “I will tell you,” he said, “why old age,
+so far from being grievous to me, is full of delight.” But
+in the end, he himself saw the weakness of his proof, and
+the note of scepticism appeared in him more strongly than
+in his predecessors, so that he came to say as follows:
+“If I am deceived as to the immortality of the soul, I am
+<span class='pageno' id='Page_170'>170</span>deceived gladly, and I would not have the belief torn from
+me while I live. If, when I am dead, all feeling is arrested
+within me, as some pretended philosophers hold, at least
+I have not to fear that after my death they will come and
+mock me for my error.”</p>
+
+<p class='c007'>Scepticism becoming more and more definite, belief in
+the immortality of the soul persisted only in the purely
+religious form. Philosophical systems freed themselves of
+it, and replaced it by a vague form of pantheism.</p>
+
+<p class='c007'>Seneca tried to support the thesis of immortality, but
+one gets the impression strongly that there was no vigour
+in his belief. He is content with poetry rather than with
+reason. “The events of this mortal life,” he wrote in one
+of his celebrated “Letters,” “are the mere prelude of a
+better and more lasting existence. As our mother’s womb,
+bearing us for nine months, shapes us not to live there for
+ever, but for our place in this world in which it places us,
+with the strength to breathe this air and to withstand surrounding
+things: so, also, the time that passes from our
+infancy to our old age is a preparation for a second birth.
+Another beginning and another world await us. Until
+then, we could not endure, save from afar, the splendour
+of the heavens. Learn then, O man, to face without a
+shudder the decisive hour, the last hour of the body, but not
+of the soul. What you see around you consider but as
+the furniture of an inn; soon you are going further on.
+The day that you dread as your last day is your birthday
+into immortality.”</p>
+
+<p class='c007'>In the midst of these glowing visions, however, Seneca
+is assailed by dark and gloomy thoughts. “Yes,” he cried,
+“all that is must perish; death comes to every living thing.
+Every day, every hour, reveals to man the coming of death;
+there is always some new lesson to remind him of the fragility
+<span class='pageno' id='Page_171'>171</span>he had forgotten, and from a dream of eternity to turn
+his thoughts to the grave.”</p>
+
+<p class='c007'>These heights and depths of spirit led Seneca towards a
+new theory in which he gave a final expression of his views
+on the great problem of human existence. “All beings
+pass through definite stages; they must be born, grow and
+die. The stars that we see revolving above us, the earth
+on which we are carelessly scattered and which seems to us
+so solid; all is threatened and all will come to an end.
+Old age comes on everything; although the period is very
+different, the same end comes to everything. Everything
+that now is will cease to be; but for all that the world will
+not perish; it will dissolve. Dissolution is destruction for
+us. As a matter of fact we think of things only as they
+concern ourselves; our degenerate soul, incapable of detaching
+itself from the body, sees nothing beyond that; none
+the less we should endure the idea of the death of ourselves
+and of those near to us with a greater fortitude were we to
+realise that nature is a constant routine of birth and death,
+that all composite bodies must dissolve, that the dissolved
+substances reform, and that the creative power of God
+displays itself in this cycle of change throughout the universe.”
+From such a final conception of the universe he
+draws the consolation: “A great soul should know how
+to obey God and submit willingly to the order of the universe.
+If it be not for a better life that we are to quit this
+life, if not to find a home in the skies more tranquil and
+more brilliant, our souls, free from suffering, will return to the
+spirit that gave them birth and will mingle in the great all.”</p>
+
+<p class='c007'>In other words, abandoning the image of life after death
+that played so consoling a part in primitive beliefs, philosophy
+became content to advocate resignation to the
+inevitable laws of nature, and to console itself with the
+<span class='pageno' id='Page_172'>172</span>promise of a vague return to some universal, eternal
+principle.</p>
+
+<p class='c007'>The conceptions of the Stoics, especially in the form
+presented by Seneca, found an ardent and brilliant exponent
+in Marcus Aurelius, whose “Thoughts” are known to all
+the world. He had much to say of the problem of death
+and of the attitude of the philosopher towards it. “Death,”
+said Marcus Aurelius, “like birth, is one of nature’s mysteries.
+In the two are present the same elements: in the
+one case in the phase of combination, in the other in that of
+dissolution.” In death “there is nothing repugnant to the
+essence of an intelligent being, nor to the general plan of
+our nature.” But his ideas on death were vague. “Death
+may perhaps be a dispersal or resolution into atoms, or
+an annihilation in the sense of extinction or deplacement.”
+“Alexander of Macedon and his mule-driver were reduced
+at death to the same condition, that is to say they returned
+alike to the originating principle of the universe, or one
+and the other were scattered as atoms.”</p>
+
+<p class='c007'>Although he was definitely a deist, Marcus Aurelius was
+undecided as to the immortality of the soul. “If souls have
+not disappeared,” he said, “how can the air contain the
+eternal generations of them?” “Remember well,” he
+said in another place, “that that feeble and composite
+creature, your soul, will one day resolve into its atoms;
+the faint spark of life will be extinguished, or be assigned
+to some other dwelling-place.” Clearly enough, there was
+no consoling hope of a future life to be derived from these
+halting dubieties. It was needful to replace by some other
+anodyne the belief that for so long had brought comfort
+to poor humanity.</p>
+
+<p class='c007'>Marcus Aurelius tried to counteract the fear of death
+by the following reflection: “To fear death is to fear either
+<span class='pageno' id='Page_173'>173</span>being deprived of all feeling or being subjected to some other
+kind of feeling. But, if we are deprived of all feeling, we
+shall have no evil to fear; if we are to find new kinds of
+sensations, our existence will be different, but still existence.”
+However, he probably realised the weakness of such a
+consolation, for he tried to link the problem of death with
+the general principles of human conduct.</p>
+
+<p class='c007'>As I mentioned in the first chapter of this volume, Marcus
+Aurelius, like many of the philosophers of antiquity, held
+the view that man ought to live according to the dictates
+of human nature. The theory recurs again and again
+in his “Thoughts.” “The fig tree lives according to its
+kind, the dog like the dog, bees like bees, and man like
+man.” He expresses this view still more emphatically in
+the following words: “Man must live in conformity with
+the laws of his nature.” “No one will prevent you from living
+according to the laws of nature, and nothing can happen
+to you that is not in accordance with nature’s universal
+law.” “Neither hand nor foot can do that which is contrary
+to the laws of nature, because the foot can only fulfil the
+functions of the foot, and the hand those of the hand.
+Similarly with man, to behave as a man is not to defy
+nature’s laws, because it is only fulfilling the functions of
+man. And that which is not against nature cannot be
+evil.”</p>
+
+<p class='c007'>Being full of this theory, Marcus Aurelius applied it to death,
+which, being a natural phenomenon, was to be accepted
+without protest. “For, after all, nature forges the links
+and nature breaks them. Is she about to sever them?
+Very well, let us then say farewell as if we were taking
+leave of our friends, but let there be no tearing of the heart
+strings, and let us go willingly, and so avoid being dragged
+away. This, too, is in accordance with the laws of nature.”
+<span class='pageno' id='Page_174'>174</span>“Philosophy,” according to Marcus Aurelius, “is to await death
+peacefully, and to regard it as merely the dissolution of
+the elements which compose the human frame. Such is
+the law of nature, and whatever is in conformity with
+nature is not evil.”</p>
+
+<p class='c007'>Death, being a phenomenon in conformity with nature,
+must be submitted to. “Do not abuse death,” advises
+Marcus Aurelius, “but accept it with resignation, as being
+in accordance with the will of nature. Do we not pass on
+from infancy to youth, grow up, and become tall and attain
+manhood? Do not our teeth come, our beards grow, and
+our hair turn white? If we marry, do we not beget children?
+Are not all such events in their due season, and the
+work of nature? Death comes through the same agency.
+It therefore behoves a wise man to approach death with
+neither anger, repugnance, nor contempt, but to await it like
+any other operation of nature.” <em>Resignation</em>, then, is what
+this form of philosophy amounts to. Not only must death
+be accepted as inevitable when it comes after a long life,
+but even if it surprise us at an unexpected time. “He who
+dies after reaching the uttermost limits of human life,”
+says Marcus Aurelius, “has reached no further than he who
+comes to a premature end. It is the same in the end,
+whether there are a hundred years to look back upon, or
+whether there are only three.”</p>
+
+<p class='c007'>In his book on Marcus Aurelius, Renan<a id='r211'></a><a href='#f211' class='c014'><sup>[211]</sup></a> compares his
+philosophy of resignation with the Nirvâna of the Buddhists.
+“Like Jesus, Çakya-Mouni, Socrates, Francis of
+Assisi, and three or four other wise men, Marcus Aurelius
+was victor over death. He could laugh at it, because it
+had no longer any meaning for him.” But, just as the
+<span class='pageno' id='Page_175'>175</span>theories of Buddha became transformed into a religion
+which promised the immortality of the soul, and as Nirvâna
+gave way to the Paradise of the Easterns with its
+delights, so the sceptical resignation of ancient philosophy
+was vanquished by Christianity with its promises of a future
+life and immortality.</p>
+
+<p class='c007'>Thus, in the course of the centuries, philosophy has been
+drowned in the floods of sentiment and of religious notions,
+and it has been a labour of Sisyphus to restore reason to
+humanity. There is the less need to follow the stages of
+this resurrection, as, in the end, they come to little. For
+long, philosophical systems set themselves the task of supporting
+the dogmas of religion by arguments independent
+of divine revelation. The gods were replaced by philosophy
+or by matter, and an effort was made to solve the
+eternal and disquieting problem of death by proving the
+immortality of the soul.</p>
+
+<p class='c007'>The philosophers of the early renaissance of human
+thought accepted the chief religious dogmas as established
+truth. Plotin regarded the immortality of the soul as a
+self-evident truth that required no proof. He argued
+against a resurrection of the body, but accepted the transmigration
+of souls.</p>
+
+<p class='c007'>Although Spinoza had given up the conception of the
+immortality of the soul in the ordinary sense, he accepted
+the Aristotelian idea that “the human spirit could not be
+destroyed absolutely with the body, but left some eternal
+remnant.” Death, in his view, was a kind of eternal life,
+a merging with the absolute, a return to the immortal and
+universal substance.</p>
+
+<p class='c007'>Philosophers have exhausted themselves in the study of
+the foundations of human knowledge with the sole object
+of demonstrating the truth of religious dogmas. In spite
+<span class='pageno' id='Page_176'>176</span>of his scepticism, Kant tried to prove the genuineness of
+human knowledge, and to found on that a conviction of
+the future life and of the existence of God. Fichte set
+himself the same task, but he was forced to recognise that
+“immortality cannot be deduced from natural phenomena,”
+and that it “is supernatural.” “Although we cannot
+understand the possibility of eternal life, it still may
+be possible, for it transcends human knowledge.” Hegel
+reached a pantheistic conclusion and believed in the human
+soul being re-absorbed by the absolute.</p>
+
+<p class='c007'>These idealistic systems, when they reached their final
+point, provoked a reaction consisting in the rejection of
+all formulas based on speculation. They were succeeded
+by a dogmatic materialism, which in its turn gave place
+to a sceptical positivism, or rather to a form of agnosticism.
+Granted the impossibility of belief in the immortality of the
+soul or in eternal life in any shape, the philosophy regarding
+death was reduced to the stoical idea that our end is
+in harmony with the laws of nature, and that it must therefore
+be accepted without protest. Resignation, therefore,
+in the fullest sense of the word, became the watchword of
+human wisdom.</p>
+
+<p class='c007'>It was only to be expected that certain courageous and
+independent thinkers should not agree with this conclusion,
+and attempt to discover some other solution of the
+great problem absorbing mankind. Thence arose pessimism,
+the philosophic theory which became so prevalent during
+the last century, and which claims so many adherents in
+the present day. Pessimism, like belief in the immortality
+of the soul and the advocacy of resignation to the evils which
+beset humanity, is the product of the East, and India was
+probably its nursery. A pessimistic view of life is a salient
+feature of Brahminism, but Buddhism develops even more
+<span class='pageno' id='Page_177'>177</span>fully the doctrine that everything of this world is evil.
+That “life is made up of suffering” is the inexhaustible theme
+which, whether in the shape of philosophical argument, or
+in the more attractive form of poetry, the Buddhist Scriptures
+din ceaselessly in our ears.<a id='r212'></a><a href='#f212' class='c014'><sup>[212]</sup></a></p>
+
+<p class='c007'>In Europe, the lyrical poets introduced the pessimistic
+conception of the world, attracted by its emotional appeal.
+At the beginning of the nineteenth century, Byron struck
+this sad note, and expressed the view in the clearest fashion,
+that if we weighed our hours of joy against our days of
+pain, we should perceive clearly that whatever our life had
+been it were better not have been. In the following
+lines his conception of life is apparent:—</p>
+
+<div class='lg-container-b c022'>
+  <div class='linegroup'>
+    <div class='group'>
+      <div class='line'>“Our life is a false nature,—’tis not in</div>
+      <div class='line'>The harmony of things, this hard decree,</div>
+      <div class='line'>This uneradicable taint of sin,</div>
+      <div class='line'>This boundless Upas, this all-blasting tree,</div>
+    </div>
+    <div class='group'>
+      <div class='line'>Whose root is earth, whose leaves and branches be</div>
+      <div class='line'>The skies, which rain their plagues on men like dew—</div>
+      <div class='line'>Disease, death, bondage—all the woes we see—</div>
+      <div class='line'>And, worse, the woes we see not—which throbs through</div>
+      <div class='line'>The immedicable soul, with heart-aches ever new.”</div>
+      <div class='line in44'>“<span class='sc'>Euthanasia.</span>”</div>
+    </div>
+  </div>
+</div>
+
+<p class='c007'>In chap. vi. I showed that Byron was haunted by a
+fear of death which ultimately led him to a recognition of
+the instinctive character of the feeling. He, however, like
+the other pessimistic poets (Leopardi), did not regard the
+world as being merely part of a universal system, and it was
+left to philosophy to come to this conclusion.</p>
+
+<p class='c007'>During the first half of the nineteenth century, Schopenhauer
+endeavoured to give a presentation of a pessimistic
+theory, borrowed from Hindoo religions and from the views
+of contemporary poets, in the form of a rational philosophy.
+<span class='pageno' id='Page_178'>178</span>He developed a conception of life according to which “existence
+is to be regarded as something one is better without,
+as a kind of mistake which should be remedied when recognised.”<a id='r213'></a><a href='#f213' class='c014'><sup>[213]</sup></a>
+According to Schopenhauer existence is wrong,
+and results from the gratification of unrestrained desire.
+“If an attempt be made to realise the amount of misery,
+pain, and evil of all kinds, that the sun shines upon in its
+daily course, it will be seen how much better it would be
+were the earth to exhibit as few phenomena of life as the
+moon, and if the surface of the earth were in a similarly
+crystallised condition. Human life might equally be interpreted
+as a useless disturbance of the exquisite tranquillity
+of nothingness,” the meaning of the disturbance being
+wrapped in impenetrable mystery.<a id='r214'></a><a href='#f214' class='c014'><sup>[214]</sup></a></p>
+
+<p class='c007'>This melancholy state of life was the result of the cosmic
+process, which has created so much evil, and which finally
+evolved the human species, capable of feeling and appreciating
+to the full the pain of the world. The lower animals
+he regards as happier than man, their senses being less fully
+developed, and being unconscious of the worst aspects of
+their existence. In man, pleasure is purely a negation,
+whereas the sensation of pain is passive, contemplation,
+a human monopoly, rendering suffering still more unbearable.
+“Man’s capacity for pain increases far more with the
+passage of time than does his capacity for enjoyment, and
+is especially increased by his foreknowledge of death.
+Animals only fear death from instinct, without having any
+real knowledge of it, and without having the prospect of it
+always before their eyes, as is the case with human beings.”<a id='r215'></a><a href='#f215' class='c014'><sup>[215]</sup></a>
+Schopenhauer was convinced that happiness should not be
+regarded as the aim of life. “The greatest mistake we
+<span class='pageno' id='Page_179'>179</span>can make,” he said in his principal work,<a id='r216'></a><a href='#f216' class='c014'><sup>[216]</sup></a> “is to imagine
+that we are placed here to be happy.” “So long as we continue
+in this erroneous view which optimistic doctrines
+serve to foster, the world will continue to seem a mass of
+contradictions to us.” “It would be nearer the truth to
+regard pain as the aim of life rather than pleasure.” “The
+destiny of all human existence seems to be suffering. Life
+is wrapped about with evil, and cannot be protected from
+it. Life, at its very beginning, is signalised by tears, its
+course is fundamentally tragic, and still more tragic is its
+end. It is impossible to ignore that all this is meant to be.”
+“Death is the real goal of life. Its attainment brings a solution
+of all that has gone before.”</p>
+
+<p class='c007'>The prospect and expectation of death, being products of
+reason, are experienced by men and not by animals. “Only
+in the case of humanity is the will capable of renouncing
+and withdrawing from life.”</p>
+
+<p class='c007'>What is the answer to all these contradictions and the
+explanation of a cosmic process which on the one hand
+leads but to death, and on the other hand develops the
+intelligence so as to enable it to fear and dread the inevitable
+end? Is the solution to be found in belief in the immortality
+of the soul, supported as it is not only by nearly every
+form of religion, but by numerous systems of philosophy?
+Schopenhauer devotes many pages to the discussion of this
+question. He neither supports the doctrine of the resurrection
+of the body, nor the immortality of the conscious
+soul. “Just as the individual has no memory of prenatal
+existence, so after death he will remember nothing of his
+present life.”<a id='r217'></a><a href='#f217' class='c014'><sup>[217]</sup></a> “Those who regard birth as the actual
+beginning of man’s life must necessarily face death as final,
+<span class='pageno' id='Page_180'>180</span>the two being parallel. No man can therefore regard himself
+as immortal without forfeiting his belief in his own birth.
+Birth and death have the same origin and the same significance.
+They represent but one line, extending in opposite
+directions. If birth implies an origin from nothingness,
+then death must be complete annihilation.”<a id='r218'></a><a href='#f218' class='c014'><sup>[218]</sup></a></p>
+
+<p class='c007'>There is no such thing as individual immortality. But,
+according to Schopenhauer, to desire such immortality
+would merely be to advocate “the eternal perpetuation of
+a great mistake. Each individual existence is a definite
+mistake, a blunder, something that would better not have
+been, and the object of existence should be to end it.”<a id='r219'></a><a href='#f219' class='c014'><sup>[219]</sup></a></p>
+
+<p class='c007'>But if man, as an individual, is mortal, “death only takes
+away what was given by birth, that is to say, the principle
+by which death itself became possible.”<a id='r220'></a><a href='#f220' class='c014'><sup>[220]</sup></a> “Consciousness
+ceases at death, but the cause which produced that consciousness
+persists; life comes to an end, but not the
+principle which became manifest by life.”<a id='r221'></a><a href='#f221' class='c014'><sup>[221]</sup></a></p>
+
+<p class='c007'>What then is this immortal principle? It is the idea of
+the species or genus. Men or dogs, as individuals, perish in
+due course, but the human species or the canine species,
+the man “idea” or the dog “idea,” endures. Here Schopenhauer
+reverted to the conception of Spinoza, who, indeed,
+denied the immortality of the soul, but none the less believed
+in the immortality of the principle of life. This everlasting
+principle, according to Schopenhauer, is the will
+in its widest and most metaphysical sense, while, on the
+other hand, the mortal soul is the reason, a product of the
+functions of the brain.</p>
+
+<p class='c007'>The eternal principle of life cannot be defined, because
+“we cannot pass outside the limits of our consciousness.
+<span class='pageno' id='Page_181'>181</span>And thus the problem of what it is in itself cannot be
+resolved.”<a id='r222'></a><a href='#f222' class='c014'><sup>[222]</sup></a></p>
+
+<p class='c007'>Schopenhauer himself recognises that this solution of
+the problem is not satisfactory from the point of view of
+those who desire reassurance of their immortality. “But,”
+he continues, “it is better than nothing, for those who
+dread death from the point of view of absolute annihilation
+should not despise the certainty of the persistence of the
+most vital principle of life.”<a id='r223'></a><a href='#f223' class='c014'><sup>[223]</sup></a> He further remarks that
+it must be remembered that nature is interested only in
+the preservation of the species, being indifferent to the
+individual. We ourselves being only a part of nature ought
+to further its plans. “If we wish to attain to a wider

+with it, and regard life and death indifferently.”<a id='r224'></a><a href='#f224' class='c014'><sup>[224]</sup></a>
+Schopenhauer himself feels that his theories and arguments
+are unsatisfactory. When he had reached the full development
+of his doctrine, he admitted that it was negative in
+character, and that it ended in negation. It spoke only
+of what it had to deny and of what ought to be abandoned.
+It was obliged to regard as nothingness all that could be
+acquired in the future. As a consolation, he added that he
+meant relative nothingness, and not absolute nothingness.</p>
+
+<p class='c007'>As an ultimate aim, there remained nothing but abrogation
+of the will to live, and thus misery and wretchedness,
+which are the inseparable accompaniments of human life,
+led to resignation.</p>
+
+<p class='c007'>As our life is no more than a succession of misfortunes,
+and as, according to Schopenhauer, death is the plain conclusion
+of philosophy, the end of the individual life must be
+pleasant. As a general rule, he said, the death of a well-regulated
+life is calm and peaceful. But the privilege of
+<span class='pageno' id='Page_182'>182</span>dying willingly, with joy and delight, is reserved for him
+who has learned resignation, and has abolished and abandoned
+his will to live. For such an one would be willing
+to die in reality, not merely in appearance, and would neither
+desire nor claim a personal immortality. He would give
+up readily the existence that we know. Whatever may
+replace that existence is nothing from the point of view of
+individuality. The Buddhistic faith called the position
+attained by him who had given up the will to live, “Nirvâna,
+or nothingness.”<a id='r225'></a><a href='#f225' class='c014'><sup>[225]</sup></a></p>
+
+<p class='c007'>The natural deduction from this pessimistic doctrine of
+Schopenhauer would be to abolish the will to live by
+abolishing our individual life by suicide. But such is not
+the advice of the philosopher. He is far, however, from
+agreeing with those who regard suicide as criminal.<a id='r226'></a><a href='#f226' class='c014'><sup>[226]</sup></a> He
+merely does not admit that it solves the question. “He
+who commits suicide destroys the individual only, and not
+the species.” “Suicide is the voluntary destruction of a
+solitary phenomenon, without in the smallest degree affecting
+the system as a whole.”<a id='r227'></a><a href='#f227' class='c014'><sup>[227]</sup></a></p>
+
+<p class='c007'>The will to live manifesting itself, according to Schopenhauer,
+by the creation of new individuals, the philosopher
+would naturally, in accordance with his views of life, abstain
+from bringing others into the world. Schopenhauer lived
+and died a bachelor, and, so far as I am aware, had no children.
+On the other hand, convinced that the solution of life’s
+problem did not lie in suicide, he clung tenaciously to life.
+Having relinquished a belief in the immortality of the soul,
+he fell back upon a belief in the persistence of some ultimate
+principle, apart from conscious life, and held that in resignation
+and desire for annihilation (Nirvâna, according to
+<span class='pageno' id='Page_183'>183</span>his interpretation of the Buddhist doctrines) lay the true
+consolation for all the evils of human existence.</p>
+
+<p class='c007'>For a long time Schopenhauer’s views found no echo in
+the opinions of other thinkers. Later, however, they became
+more and more widely diffused, and philosophic pessimism
+became quite fashionable. Those who did not adopt the
+metaphysical principles of Schopenhauer’s philosophy
+agreed with his views on life and on the impossibility of
+happiness.</p>
+
+<p class='c007'>Exactly half a century after the publication of Schopenhauer’s
+principal work,<a id='r228'></a><a href='#f228' class='c014'><sup>[228]</sup></a> another German philosopher,
+E. Hartmann,<a id='r229'></a><a href='#f229' class='c014'><sup>[229]</sup></a> went a step further in the same direction.
+Without agreeing wholly with his metaphysics, he
+shared Schopenhauer’s views on the impossibility of regarding
+happiness as the true aim of existence. In order to
+demonstrate this theory, he examined the three phases of
+illusion through which mankind passes. He held that, in
+the first phase, people imagined happiness to be attainable
+during the present life. However, all that have been regarded
+as the sources of joy—youth, health, desire, conjugal love,
+family love, glory, etc.—end in disillusion. Love itself is
+especially submitted to Hartmann’s implacable criticism.
+According to him, there can be no question but that “love
+causes far more suffering than pleasure to those concerned.”<a id='r230'></a><a href='#f230' class='c014'><sup>[230]</sup></a>
+“It cannot be doubted,” he says, “that reason would prompt
+a total abstention from love,” and, as a means to this end,
+he recommends “the extinction of sexual desire by castration,
+if that could be relied upon to destroy desire.”<a id='r231'></a><a href='#f231' class='c014'><sup>[231]</sup></a> That,
+according to Hartmann, “is the only possible means of
+securing the happiness of the individual.” It is at the
+<span class='pageno' id='Page_184'>184</span>sacrifice of his personal happiness that man permits himself
+to love, and so abets the evolution of the cosmic process.</p>
+
+<p class='c007'>“When they have become convinced of the impossibility
+of obtaining happiness in this world, people persuade themselves
+that it may be obtained after death in a transcendental
+life in another world. This, however, is only a second
+phase of illusion, and is based upon faith in life after death
+and eternity. It is certain, however, that the individuality
+of the organic body as well as that of the mind is only a
+delusion which ceases with death.”<a id='r232'></a><a href='#f232' class='c014'><sup>[232]</sup></a> Hartmann says in
+conclusion that “it is therefore plain that the hope of the
+immortality of the individual soul is also a mere illusion.
+And thus the chief support of the Christian promises is
+cut away; for men are devoted to their dear selves, and take
+little interest in a future happiness in which they themselves
+are to have no share.”<a id='r233'></a><a href='#f233' class='c014'><sup>[233]</sup></a></p>
+
+<p class='c007'>Being disillusioned regarding the possibility of obtaining
+happiness in this world, or in a future state, humanity falls
+back upon a third illusion. Firmly convinced that the aim
+of life is true happiness, man concluded that it was only
+attainable in some future state of the cosmic process. This
+hypothesis is based upon belief in a system of progressive
+development. “This,” declares Hartmann, “is yet another
+mistake. Humanity may progress as much as it likes,”
+he says, “but it will never succeed in suppressing or even
+diminishing the greatest evils which beset it: disease, old
+age, dependence on the wishes or the power of others,
+misery and discontent. Notwithstanding the new remedies
+which are discovered, the number of diseases, especially
+those of a chronic nature which are so trying, continues to
+increase at a rate that medicine cannot keep pace with.
+Joyous youth will always constitute a small portion of
+<span class='pageno' id='Page_185'>185</span>humanity, while the greater part will consist of melancholy
+old age.”<a id='r234'></a><a href='#f234' class='c014'><sup>[234]</sup></a></p>
+
+<p class='c007'>Against this idea that the happiness of the race will be the
+eventual result of progress, Hartmann employs the following
+arguments: “The happiest people are those who are
+the rudest and most primitive, and, among civilised races,
+the uneducated classes. It is well known that the progress
+of education increases discontent. The progress of
+science contributes little or nothing to the absolute happiness
+of the world. Practically speaking, this progress is of
+advantage to politics, social life, morality, and the arts;
+but factories, steam-boats, railways, and telegraphs, have
+so far done no positive good to humanity.”<a id='r235'></a><a href='#f235' class='c014'><sup>[235]</sup></a> Hartmann
+frequently recurs to the conclusion that the primitive are
+happier than the civilised, and that “the lower classes,
+inferior and rude, are happier than the rich who are well
+educated and great; that idiots are happier than the intelligent,
+and that, as a general rule, the less sensitive a man’s
+nervous system may be, the happier he is, as his capacity
+for feeling pain is not so much in excess of his capacity for
+enjoyment, and his illusion is therefore greater. With the
+progressive development of humanity, however, not only
+is there an increase in the extent of human needs, but in the
+sensitiveness of the nervous system, and in the cultivation
+of the mind. In consequence, the balance of pain over
+pleasure increases, and the illusion is destroyed, that is to
+say, knowledge comes of the misery of life, of the vanity of
+most of the pleasures. Misery itself increases as much as
+knowledge of misery, as experience has shown; and the
+apparent increase of happiness in the world, due to the
+progress of universe, is merely superficial.</p>
+
+<p class='c007'>Having reached this extremely pessimistic conclusion, that
+<span class='pageno' id='Page_186'>186</span>it is impossible for humanity to attain happiness, Hartmann
+proceeds to inquire into the real destiny of man. He would
+be no true philosopher if he did not hold that the world was
+created according to a general plan, and that it follows a
+regular course tending towards a definite end. “We have
+seen,” he says, “how that in the present world all has been
+arranged in the wisest, and for the most part the best way,
+and that it should therefore be regarded as the best possible
+of worlds. Notwithstanding this, however, it is supremely
+miserable, and worse than if it did not exist at all.”</p>
+
+<p class='c007'>Being convinced of the illusory nature of its hopes,
+humanity “must definitely renounce all pretensions to
+positive happiness, and aspire only to a freedom from pain,
+to annihilation or Nirvâna. This, however, must not be
+merely the attitude of solitary individuals, but humanity
+at large must cry out for annihilation. This is the only
+possible outcome of the third and last phase of illusion.”</p>
+
+<p class='c007'>By what means is this end to be attained? Hartmann
+is no advocate of suicide as the best remedy of the evils
+of human existence. Upon this point he agrees with Schopenhauer,
+and thinks that such a course would have no
+effect upon the general progress of the cosmic process. A
+renunciation of pleasure—asceticism—would present no
+better solution of the problem. Even abstinence from reproduction
+would not serve the purpose. “What good would
+it do,” says Hartmann, “if humanity were to cease to be
+by means of sexual abstinence? This unfortunate universe
+would continue to exist, and the Unconscious would
+immediately take advantage of the opportunity to create
+a new man or some other similar type.”<a id='r236'></a><a href='#f236' class='c014'><sup>[236]</sup></a> Thus it is not
+the disappearance of mankind that should constitute our
+aim, but “the complete abandonment of the individual to
+<span class='pageno' id='Page_187'>187</span>the cosmic process, in order that the latter may accomplish
+its end and bring about the universal deliverance of the
+world.”<a id='r237'></a><a href='#f237' class='c014'><sup>[237]</sup></a> This being so, the instinctive love of life reasserts
+itself, and it becomes necessary to admit, at least as provisional
+truth, “the validity of the will to live; for it is
+only by complete resignation to life and its troubles, and not
+by cowardly renunciation and abandonment, that one may
+contribute one’s share in the development of the cosmic
+process.”<a id='r238'></a><a href='#f238' class='c014'><sup>[238]</sup></a></p>
+
+<p class='c007'>Hartmann’s proposed solution of the problem of human
+existence belongs undoubtedly to the category of systems
+advocating resignation. He is unable to tell us what is the
+cosmic process to which he bids man lend all his forces.
+He advises humanity to continue to live and to multiply
+in the full certainty that happiness cannot be attained.
+Hartmann obviously demands a true renunciation and an
+absolute submission. His solution has the appearance of
+being more exact, and of furnishing a guide to human conduct
+more clear than that vague aspiration to Nirvâna proposed
+by Schopenhauer. But on closer investigation it
+becomes at once plain that the greater precision is illusory.</p>
+
+<p class='c007'>It is easy to see, under such circumstances, that a school
+of criticism or negation of the pessimistic doctrines should
+have gained many adherents. Very few, on the other
+hand, have embraced pessimistic doctrines because of any
+power being inherent in them to resolve the difficulties of
+life. A German pessimistic philosopher, Mailaender,<a id='r239'></a><a href='#f239' class='c014'><sup>[239]</sup></a> shared
+fully Schopenhauer’s opinions as to the misery of human
+life, but opposed the latter’s doctrine of resignation and
+Nirvâna as the solution of the general problem of life.
+<span class='pageno' id='Page_188'>188</span>Mailaender accepted the three stages of human illusion as
+expounded by Hartmann, but attacked vigorously the view
+of facilitating the cosmic process by acquiescence in the
+will to live. “Indeed,” he cried, “your advice is that we
+should sacrifice ourselves to the cosmos, we are to choose
+a career, to learn a trade, acquire money, property, fame,
+power, and so forth; we are to marry and to beget offspring;
+by such advice you are merely undoing with your own
+hands the sole merit of your work, the analysis of illusion.
+You suddenly advise the very man who has got behind all
+these illusions to succumb to them again, as if an illusion,
+although it has been recognised, could still deceive and exercise
+its power.”<a id='r240'></a><a href='#f240' class='c014'><sup>[240]</sup></a></p>
+
+<p class='c007'>Mailaender takes an entirely different view of the problem.
+Like his predecessors, he is convinced of the futility of happiness,
+but he has achieved an original view of the cosmic
+process. He holds that an unaccountable and divine Being
+existed before the creation of the world. Before disappearing
+“this divinity gave birth to the universe.” By this
+means, complete annihilation was made possible. “The
+world,” says Mailaender, “is but the means for bringing
+about a condition of non-existence, and is the only possible
+means by which that end could be attained. God knew
+that only by creating a real world could we pass from
+existence into non-existence.” Maileander regards as certain
+“that the universe tends towards universal non-existence.”<a id='r241'></a><a href='#f241' class='c014'><sup>[241]</sup></a>
+This tendency is characterised by the weakening
+of the total amount of energy, so that “every individual at
+the close of the weakening process to which his energy is
+submitted, is led in the course of his development to the
+point at which his desire for annihilation may be fulfilled.”<a id='r242'></a><a href='#f242' class='c014'><sup>[242]</sup></a>
+<span class='pageno' id='Page_189'>189</span>Life on our planet, he says, ought to be regarded as a halting-place
+on the road to death. In order to appreciate fully the
+happiness brought by death, it is necessary first to taste of
+life, and that is why the instinct of self-preservation is so
+well developed in animals. Man passes first through a
+phase of development in which he is like any other animal.
+“As with them, the will to live is stronger than the will to
+die. Life is clung to with extreme pertinacity, and death
+is proportionately execrated.” “At first, not only the fear
+of death increases, but equally the love of life.” Terror of
+death becomes acuter. Animals, knowing nothing of death,
+only fear it instinctively through their perception of approaching
+danger. Man, on the contrary, knows of the existence of
+death and what it means. He looks back on his past life
+and wonders what the future may hold in store, and realises,
+infinitely more than animals realise it, the dangers that
+threaten him. During this phase, man does all in his power
+to keep death at bay, and to make his life as happy as
+possible. This, however, is not the last stage of his development.
+The thinking man soon comes to the conclusion that
+a craving for life is not the true aim of the universe; it is
+only the means for attaining to a knowledge of the definite
+aim of existence, which is the cessation of life. Philosophy
+soon shows that perfect happiness is not possible, and that
+only death is really desirable. In summing up the cosmic
+process, the conclusion arrived at is “that throughout the
+universe the desire of death exists in a form more or less
+masked, but that in the organic world this assumes the form
+of a will to live.”<a id='r243'></a><a href='#f243' class='c014'><sup>[243]</sup></a> In the end, however, the desire of
+death becomes more and more plain, until the philosopher
+can see “in the whole universe nothing but a longing for
+absolute extinction, and fancies that he can hear the cry
+<span class='pageno' id='Page_190'>190</span>rolling from star to star, ‘Deliverance, deliverance, death
+to our life!’ and the echoing cry of consolation, ‘Extinction
+and deliverance await you all!’”<a id='r244'></a><a href='#f244' class='c014'><sup>[244]</sup></a></p>
+
+<p class='c007'>In order to explain in a clearer way the progress of this
+evolution, Mailaender describes the state of mind of a man
+who develops the will to die, and commits suicide. “At first
+he glances anxiously and from afar at death, and shrinks from
+it with horror. Later, he draws nearer and walks round
+it in wide circles. Day by day, however, these circles become
+smaller, until finally he embraces Death with weary arms
+and looks it straight in the face. Then Peace comes; gentle
+Peace!”<a id='r245'></a><a href='#f245' class='c014'><sup>[245]</sup></a></p>
+
+<p class='c007'>It is absurd to expect anything to follow death but absolute
+annihilation, and the ordinary man faces this prospect
+with terror. “But it is essential,” says Mailaender, “that
+man should dominate the universe by knowledge, and wise
+men look forward to total annihilation with joy.”<a id='r246'></a><a href='#f246' class='c014'><sup>[246]</sup></a> “In
+relinquishing Schopenhauer’s will to live,” concluded Mailaender,
+“I have finally arrived at the will to die. I have
+raised myself upon the shoulders of Schopenhauer, until I
+have attained a point of view such as others have never
+accomplished. At present I am alone, but behind me all
+humanity is pressing on to freedom; and before me is the
+clear translucent vista of the future.”<a id='r247'></a><a href='#f247' class='c014'><sup>[247]</sup></a></p>
+
+<p class='c007'>I have quoted these views, not because of the solidity
+of Mailaender’s arguments, but merely because this
+pessimistic philosopher proved himself to be more consistent
+than his predecessors. While Schopenhauer and
+Hartmann, both so firmly convinced of the non-existence
+of happiness and the vast preponderance of suffering in
+all imaginable conditions of life, lived out their lives,
+<span class='pageno' id='Page_191'>191</span>Mailaender, true to his principles, committed suicide when
+barely thirty-five years of age.</p>
+
+<p class='c007'>This is probably not a solitary instance. Under the
+influence of pessimism, a certain number of young persons,
+especially those whose mental equilibrium is not very firmly
+established, follow in the tragic footsteps of Mailaender.
+Some commit suicide, while others abstain from taking part
+in the perpetuation of the race. Others, but these are not
+many, curtail their existence by dissipation, thinking life
+not worth the care of it.</p>
+
+<p class='c007'>A modern writer of great talent, Maeterlinck, echoes
+the pessimism of the present generation. “It is plain,”
+he says,<a id='r248'></a><a href='#f248' class='c014'><sup>[248]</sup></a> “that from one point of view humanity will
+always seem wretched, and as though being dragged towards
+a fatal precipice, since it will ever be doomed to disease,
+to the inconstancy of matter, to old age and to death.”
+“Yes, human life as a whole is sad, and it is easier, I
+may almost say pleasanter, to discuss and expose its dark
+side, than to enumerate its consolations and make the best
+of them. The miseries of life are many, obvious, and
+never failing; whereas the consolations, or rather the
+reasons which cause us to fulfil with alacrity the duty of
+living, are rare, hard to seek, and precarious.”</p>
+
+<p class='c007'>Although pessimism has been greatly developed and widely
+spread during the nineteenth century, dissentient voices in
+opposition to this negative attitude towards the things of
+this world have not been wanting. Take the views of the
+German poet, Robert Hammerling,<a id='r249'></a><a href='#f249' class='c014'><sup>[249]</sup></a> who reproaches the
+pessimistic philosophers with ignoring the attitude of mind
+of the majority of mankind who ask but one thing,—life—life
+<span class='pageno' id='Page_192'>192</span>at any price and under any conditions. Against this
+sentiment all dogmatic arguments are useless, for, according
+to Hammerling, the question of pleasure and pain is a matter
+of feeling and not of reason. Now, with regard to the general
+feeling of humanity, there can be no doubt—it is frankly
+optimistic.</p>
+
+<p class='c007'>Max Nordau, the well-known writer, supports a similar
+theory. According to him, all living nature betrays its
+optimistic foundation. “The truth is,” he says, “that optimism,
+limitless and irradicable optimism, constitutes the
+fundamental attitude of man, and is the instinctive feeling
+which governs him under all circumstances. All other forms
+of life confirm this truth....” “All nature,” according
+to Max Nordau, “by the bells of flowers and the throats of
+her birds, rings and proclaims the truth of optimism.” “No
+animals feel the pain of the world; and our own ancestor,
+the contemporary of the cave bear, was certainly free from
+all anxiety relating to the destiny of the human race.”</p>
+
+<p class='c007'>These arguments do not take into account that, to be
+true, pessimism need not necessarily be felt and agreed with
+by all living creatures. Birds and other animals, happy in
+their lives, that is to say optimists, know nothing of the
+inevitability of death. Our cave ancestors knew nothing
+of it either. If the greater portion of modern humanity is
+optimistic, that might be accounted for by its being still
+under the influence of one of the three phases of illusion
+alluded to by Hartmann. It is only when the highest stage
+of development is reached that man, being convinced of the
+futility of his hopes, arrives at a pessimistic conception of
+the universe.</p>
+
+<p class='c007'>Max Nordau disclaims discipleship of Doctor Pangloss,
+who held that the world is the best of all possible worlds.
+But his arguments reveal a pronounced optimism. He
+<span class='pageno' id='Page_193'>193</span>regards pain as an indispensable factor of the maintenance
+of life. “Without pain,” he says, “our lives would not
+endure an hour, for we should be unable to recognise dangerous
+symptoms and guard against them.” Insensibility
+to pain is often so grave a symptom that sick people rejoice
+when they are again able to feel the prick of a needle.</p>
+
+<p class='c007'>This is true enough, but none the less the feeling of pain
+is very erratic in both animals and human beings. Quite
+insignificant causes and unimportant illnesses, such as certain
+forms of neuralgia, give rise to unbearable agony. A physiological
+phenomenon such as childbirth is often attended
+by extremely violent pain which is absolutely useless as
+a danger-signal. On the other hand, some of the most
+dangerous diseases, such as cancer or kidney disease, may
+exist for a long time without causing any sensation of pain,
+with the result that the sufferer knows nothing of the presence
+of the disease until it is too late. Were pain to play the
+part assigned to it by Nordau, it would appear in all cases
+of danger, and yet would never become almost unbearably
+acute.</p>
+
+<p class='c007'>But when men have passed through the three stages of
+illusion it is not physical pain which presses most heavily
+on them. Max Nordau himself admits that it is “appalling
+to think of the cessation of our consciousness, and the annihilation
+of our ego.” None the less, he believes “that we
+are so happily constituted as to be able to accept the really
+inevitable with a light heart, and that there is no ill feeling
+about the matter.” This admission is not in accordance
+with the well-established facts discussed in chap. vi.
+With very rare exceptions man does not willingly accept
+the prospect of death, especially if he be still under the
+influence of illusion in any of its three stages. As a rule
+those who desire to live feel not only a repugnance to the
+<span class='pageno' id='Page_194'>194</span>contemplation of death, but death seems to them something
+abnormal and irrational. It is no answer to assert that all
+who feel this are psychopaths, or that it is absurd to think
+that the happiness of mankind counts for something in the
+cosmic process. On the contrary, it is quite natural that
+man should seek after happiness, and that he should try to
+analyse the phenomena taking place within him and around
+him from the point of view of that ideal. For this reason
+it is quite unjust to say that pessimism cannot be treated
+seriously. It is pessimism which has been the first to draw
+up a true indictment of human nature, and if pain is to be
+regarded as useful in its quality of danger-signal we should
+equally recognise that the pessimistic view of the universe
+is a step onwards in the evolution of humanity. Without
+pessimism we might easily sink into a kind of contented
+fatalism, and end in quietism, in the manner of many religions.</p>
+
+<p class='c007'>It is only natural, however, that the thinking world should
+not accept pessimism as the last word of human wisdom,
+and that more or less noted philosophers should devote
+themselves to finding a possible solution of the problem of
+life and death. These systems of philosophy, one and all,
+have abandoned readily all belief in future life and personal
+immortality. But they have adopted pantheistic conceptions,
+and have accepted the existence of some general principle
+into which the individual consciousness will eventually
+be absorbed. There is division of opinion as to the properties
+of this principle. For some it is the Idea, for others
+Will, for others Force, or Eternal Energy.<a id='r250'></a><a href='#f250' class='c014'><sup>[250]</sup></a> The nomenclature
+is the less important as the views as to the nature
+of the general principle are absolutely vague. Accordingly
+this part of the philosophic doctrines appears in a lyrical
+form and has passed over into the domain of poetry.</p>
+
+<p class='c007'><span class='pageno' id='Page_195'>195</span>German poets have helped to spread pantheistic conceptions
+very widely. I need hardly mention Goethe, whose
+ideas were purely those of Spinoza, but Schiller’s well-known

+
+<p class='c006'>A volume might be filled with the attempts of thinkers of
+different countries to present these poetical ideas in a form
+less vague and more philosophical. I shall select only a
+few of the more modern instances.</p>
+
+<p class='c007'>Renan’s<a id='r251'></a><a href='#f251' class='c014'><sup>[251]</sup></a> ideas may be taken as typical of the compromise
+between poetry and philosophy. Speaking of immortality,
+he said “that we shall each live again by the traces
+we leave on the bosom of the Infinite.”<a id='r252'></a><a href='#f252' class='c014'><sup>[252]</sup></a></p>
+
+<p class='c007'>The views elaborated by Guyau<a id='r253'></a><a href='#f253' class='c014'><sup>[253]</sup></a> are equally poetic.
+Like so many others he is unable to accept without protest
+the prospect of the inevitability of death. Brought face to
+face with this end, he declares that he feels “not sorrow but
+indignation, as against an injustice of nature.” “It is with
+justice,” he cries, “that we look on nature as a murderess
+<span class='pageno' id='Page_196'>196</span>if she kills what is morally best in ourselves and in
+others.”<a id='r254'></a><a href='#f254' class='c014'><sup>[254]</sup></a></p>
+
+<p class='c007'>It is chiefly in the name of love that Guyau protests
+against death: “The death of others, the annihilation of
+those we love, is insupportable to men, who are essentially
+thinking and loving creatures.”<a id='r255'></a><a href='#f255' class='c014'><sup>[255]</sup></a></p>
+
+<p class='c007'>This problem, so vast and so difficult to solve, is presented
+by him as follows: “As regards the question of individual
+immortality, human thought is dragged in opposite directions
+by two great forces—science, in the name of evolution,
+prepared to sacrifice the individual completely; love, in
+the name of an evolution, morally and socially higher, which
+would preserve the individual at all hazards. There is no
+more disturbing dilemma proposed to the philosopher.”<a id='r256'></a><a href='#f256' class='c014'><sup>[256]</sup></a></p>
+
+<p class='c007'>Guyau hopes that in the course of evolution there will
+come about a merging of individual consciousness in the
+consciousness of the whole. “One may ask,” he says, “if
+it may not be that these conscious entities mingling and
+interpenetrating, may come to live on from one to the other,
+and so to acquire a new duration?” On such a hypothesis
+he can foresee “an epoch not, indeed, certain to come, but
+far from inconceivable, in which individual consciousnesses
+will have achieved a corporate integrity and a complex
+intercommunion, without themselves being lost by the
+union.”<a id='r257'></a><a href='#f257' class='c014'><sup>[257]</sup></a></p>
+
+<p class='c007'>On this hypothesis, “the problem is to be at the same
+time loving enough and loved enough to live and endure in
+another.<a id='r258'></a><a href='#f258' class='c014'><sup>[258]</sup></a>... Those who vanish and those who remain
+must love one another so greatly that the shadows cast by
+them on the universal consciousness are identical.” “We
+<span class='pageno' id='Page_197'>197</span>should then feel ourselves passing and ascending from this
+life to an immortality of love,” and “the point of contact
+between life and immortality would be discovered.”<a id='r259'></a><a href='#f259' class='c014'><sup>[259]</sup></a></p>
+
+<p class='c007'>A solution recently offered by Finot<a id='r260'></a><a href='#f260' class='c014'><sup>[260]</sup></a> is much less poetical.
+According to him, it is only “when death is conceived of as
+annihilation that it is repugnant. On the other hand, if
+we regard it merely as a change of life, we shall cease to
+fear it, and even come to love it.”<a id='r261'></a><a href='#f261' class='c014'><sup>[261]</sup></a></p>
+
+<p class='c007'>But what is this “change of life” that is to prove so
+consoling? It is the “immortality of the body,” that is
+to say, the life of the creatures developed at the expense of
+the human body. “Flies begin the work of the labourers
+on the dead,” giving birth to worm-like larvæ that writhe
+in the decomposing flesh. The same vermin that horrified
+Tolstoi when he thought of his own death (see chap. vi.
+p. <a href='#Page_123'>123</a>) became Finot’s symbol of consolation. He describes
+the whole succession of the fauna of corpses, and concludes
+by saying, “and so goes on the routine of life, from birth to
+the tomb, of noisy, clamorous life, ceaselessly renewed.
+Ever loving, giving birth, living and dying. The peace of
+the tomb is as filled with life as the dust into which we
+think our bodies will fall.”<a id='r262'></a><a href='#f262' class='c014'><sup>[262]</sup></a></p>
+
+<p class='c007'>I have given the above quotation as an instance showing
+to what lengths men have gone in their search for a solution
+of the problem of death and in their desire for a gleam of
+hope that the end may not be final. I need not say that
+this idea of the fauna of the corpse has no place in the
+philosophy of death. Thinkers, no doubt, would prefer
+the most vague ambiguities to certainties of such a nature.
+Most contemporary philosophers regard the problem in a
+very different fashion.</p>
+
+<p class='c007'><span class='pageno' id='Page_198'>198</span>In my opinion, Meyer-Benfey, a scholar at Göttingen, has
+summed up the present condition of the problem very clearly
+and exactly, in essays on Modern Religion.<a id='r263'></a><a href='#f263' class='c014'><sup>[263]</sup></a> He realises
+that it is impossible to accept the immortality of the soul.
+Personality must utterly and inevitably perish. But, just
+as no single atom of our bodies can be annihilated, so “no
+parts of our souls can be lost.” Our actions during life leave
+traces so much the deeper as the life has been fuller. It is
+this reuniting “of the actions of individuals with the life of
+the whole of humanity, that constitutes the true immortality
+or Nirvâna.” He says, too, “In accustoming our
+minds to this thought, and in educating ourselves with a
+view to the accomplishment of this end, lies the only possible
+means of overcoming the fear of death and the terror of
+annihilation.”</p>
+
+<p class='c007'>Meyer-Benfey is of the pessimistic opinion that happiness
+cannot possibly be regarded as the supreme end of humanity,
+for he thinks, if that were so, the whole course of evolution
+would have been a mistake. It would have been much
+better had evolution been arrested before the creation of the
+human race, since animals, being unaware of the inevitability
+of death, are undoubtedly happier than man. As, however,
+we have passed through the animal stage and reached the
+human stage, and achieved some measure of civilisation,
+and this not by our own desire, or as the result of mere
+chance, but guided by the inner workings of our nature, it
+is plain that the ultimate goal towards which we are advancing,
+must be some other than mere happiness. There can
+be no question but that the goal is the triumph of pure
+and perfect culture.</p>
+
+<p class='c007'>This idea, that the goal of humanity is progress in all its
+<span class='pageno' id='Page_199'>199</span>manifestations, is no recent theory, and many definitions of
+this progress have been advanced, but so far none have been
+generally accepted as satisfactory. The term “culture,”
+though vague, will have to continue in use until some
+better word conveying a more precise meaning is found to
+replace it.</p>
+
+<p class='c007'>On reviewing all the systems of philosophy which have
+attempted so strenuously to solve the problem of individual
+death, it becomes plain that all, or nearly all, of them deny
+the existence of a future life and the immortality of the
+soul. The greater part of them, however, admit some
+general principle incomprehensible but eternal, which will
+eventually incorporate within itself all individual souls.
+Feeling that these vague ideas are incapable of conveying
+consolation to poor humanity in its fear of annihilation
+through death, philosophers have persistently taught the
+advantages of resignation. Even Guyau, realising that his
+philosophy regarding the immortality of love fails to reassure
+those who look to philosophy for some word of consolation,
+ends by admitting that “as there is no help to be
+expected from the inexorable, nor mercy from that which
+is in conformity with the universe and even with our own
+judgment, resignation is best.”<a id='r264'></a><a href='#f264' class='c014'><sup>[264]</sup></a> As it is the general opinion
+that to be philosophical is to take things as they are, without
+undue protest, the watchword of all systems of philosophy
+is to bow to the inevitable, that is to say, to be resigned to
+the prospect of annihilation.</p>

+of religion in disease—Disease as a basis of pessimistic
+systems of philosophy—Advance of medical science in the
+war against disease—The revolution in medicine and surgery
+due to the discoveries of Pasteur—The beneficial results of

+Rousseau, Tolstoi, and Brunetière—Proclamation of the
+fallibility of science—Return to religion and mysticism</p>
+
+<p class='c006'>Science, the youngest daughter of knowledge, has begun
+to investigate the great problems affecting humanity.
+The chief religions and many systems of philosophy had
+been long established before the spirit of scepticism dared
+to inquire whether or no these products of the human mind
+were really in harmony with fact. Scepticism gained
+ground little by little, and open war was declared between
+religious dogma and authority on the one side, and scientific
+reason on the other.</p>
+
+<p class='c007'>The great religions and the philosophy of Aristotle had
+ruled a majority of mankind for some twenty centuries
+before doubt was cast on the real value of these doctrines.</p>
+
+<p class='c007'>Francis Bacon, Lord Verulam, asked why it was that
+all the systems of his time were so vague and so powerless
+to explain the phenomena of the world. The cause could
+not lie in nature herself, for without doubt she followed laws
+<span class='pageno' id='Page_204'>204</span>that were immutable and that could be subjected to exact
+observation; nor could it lie in any want of intelligence
+in those men who devoted themselves to solve the problems.
+The true cause of the failure lay in the falsity or insufficiency
+of the methods employed. Bacon, trying to provide a
+remedy for this condition of affairs, advised that makers
+of generalisations should proceed very slowly, passing only
+by the smallest stages from particular facts to conclusions
+only more general in the slightest degree, and so on, until
+the ultimate formula might be reached. By such a path
+it was possible to attain principles neither vague nor ambiguous,
+but clear and exact and that would not be denied
+by nature herself.</p>
+
+<p class='c007'>The first steps taken by science according to this method,
+which indeed had been suggested long ago, but which was
+first clearly laid down by Bacon, were slow and halting.
+Religious and philosophical doctrines still weighed heavily
+on inquiring minds, so that the new method was not followed
+with any great courage. None the less progress was
+achieved, until at length the great problems of humanity
+opened out. More than two thousand years before the
+birth of exact science, Buddha had given voice to the
+chief grievances of the human race. “Behold, O monks,
+the holy truth as to suffering,” he had proclaimed in the
+Sermon at Benares, “birth is suffering, old age is suffering,
+disease is suffering, and death is suffering.” Science,
+in its slow progress, passing from particular to general,
+reached first one of these four sorrows, the suffering due to
+disease.</p>
+
+<p class='c007'>In the Buddhist legend that I quoted in chap. vi.,
+the sight of a sick man “whose senses were weakened,
+who drew his breath with difficulty, whose limbs were
+shrivelled, whose bowels were wrung with pain, and his
+<span class='pageno' id='Page_205'>205</span>body pitifully soiled with excrement,” suggested to Buddha
+the reflection that “health is no more than the idle vision
+of a dream while fear and disease are horrible realities.
+What wise man, having seen the thing that life is, can still
+think of joy or of pleasure? Woe upon health which is
+assailed by so many maladies.” When Buddha, who was
+a young prince, asked of his father the gift “that he might
+always remain full of health, and that he should be smitten
+by no disease,” his father, who was the king, replied: “You
+ask me what is impossible; in that my son, I can do
+nothing.”</p>
+
+<p class='c007'>From that day, every religion has busied itself with the
+cure and prevention of disease. They believed that the
+causes of these were the influence of evil spirits or the
+visitations of God; and as remedies they prescribed sacrifice
+and prayer and anything that might avert the anger
+of God. Even at the present day, similar medicine is used
+by primitive races. In Sumatra for instance, when it is
+impossible to arrest the flow of blood from a wound, the
+disaster is ascribed to an evil spirit (Polasièq) who is sucking
+the wound and making it incurable. In Nias, when
+bleeding from the nose occurs in children, it is supposed
+to be due to the father having killed a cock during the pregnancy
+of the mother. The indispensable remedy is to make
+sacrifice to the outraged deity.</p>
+
+<p class='c007'>No doubt there co-exist with such practices of primitive
+races, certain useful rules, based on correct observation
+or on experience. It is a common practice to try all manner
+of remedies on the sick; although most do harm, now and
+again something useful may be discovered. Such vulgar
+medicine has undoubted merit, but it cannot be compared
+with the results of scientific medicine, which are drawn
+from rigorous experiment.</p>
+
+<p class='c007'><span class='pageno' id='Page_206'>206</span>Medical science has been slow in developing, but it has
+now reached a condition of which humanity may be proud.
+It is outside my purpose to give a long exposition of this
+subject; but it is necessary to my argument to set out a
+few facts from which the reader may judge of the present
+condition of medical science.</p>
+
+<p class='c007'>Without doubt the fear of disease has played a large part
+in the pessimistic conceptions of the universe. Not only
+the words of Buddha that I have quoted, but many of
+the systems of pessimistic philosophy attest this. I have
+already stated in chap. vi. that Schopenhauer in 1831 was
+driven from Berlin to Frankfurt by fear of cholera.</p>
+
+<p class='c007'>In his statement of the case against this universe, and
+as a chief argument for his proposition that “this is the
+worst of possible worlds” Schopenhauer adduced the
+spreading of epidemics. “An alteration of the atmosphere
+so slight that it cannot be detected by chemistry brings
+about cholera, or yellow fever, or the black death, diseases
+which number their victims by millions; an alteration
+slightly greater might destroy all life.”<a id='r265'></a><a href='#f265' class='c014'><sup>[265]</sup></a></p>
+
+<p class='c007'>Hartmann, who has been one of the chief advocates of
+Schopenhauer’s pessimism, also had gloomy views on
+diseases and medicine. He was convinced that howsoever
+great the progress of humanity might come to be, there
+never would be an end or even a diminution of diseases.
+“It is no matter,” he said, “how many remedies may be
+discovered for diseases; new diseases, and particularly
+chronic affections which, although not serious are extremely
+painful, will continue to appear more rapidly than the
+discoveries of medicine.”<a id='r266'></a><a href='#f266' class='c014'><sup>[266]</sup></a></p>
+
+<p class='c007'>Humanity will be fortunate if the pessimistic philosophers
+<span class='pageno' id='Page_207'>207</span>prove as wrong about their other grievances as they have
+proved about disease and medicine. To understand the
+vast progress made by medicine, it is necessary only to
+compare the complaint of Schopenhauer with the actual
+state of affairs. When he spoke of epidemics being due
+to slight changes of the atmosphere, Schopenhauer obviously
+was repeating the medical opinion current in his times.
+Experimental science has proved that he was quite wrong.
+It has been shown conclusively that two of the great affections
+of which he spoke, cholera and plague, are due not
+to chemical changes in the air, but to definite microbes,
+the natural history of which is known as well as that of
+any other plant. Cholera is produced by the vibrio, discovered
+by Koch, a minute organism that lives in water
+and that enters the human alimentary canal with food or
+drink. We do not yet know a definite cure for cholera,
+but we do know how to prevent infection. The most
+simple mode of guarding against infection is to swallow
+only material that has been boiled, and to prevent contamination
+of water or of vessels with fæcal matter containing
+the Koch’s vibrio. Moreover, in individual cases
+use may be made of anti-cholera serums. In 1831, if these
+discoveries had been made, philosophy would have taken
+a different course. Instead of trembling at the epidemic,
+and flying to Frankfurt, Schopenhauer would have remained
+quietly at Berlin, and Hegel would not have ceased to
+develop his idealism in the university of that town.</p>
+
+<p class='c007'>Schopenhauer enforced his argument by reference to
+the black death “capable of destroying millions of victims.”
+It is certain that the black death was no other than human
+plague, which made enormous ravages, in the fourteenth
+century, for instance, destroying nearly a third of the population
+of Europe. In those days, no one doubted but that
+<span class='pageno' id='Page_208'>208</span>it was a visitation of the Divine wrath, and people gathered
+in churches to make common supplication. Sacrifices
+were offered and flagellations took place in the hope of
+averting the terrible malady. Travellers who have been
+in the capital of Austria must have seen in one of the chief
+streets (Graben) a large and unlovely monument, erected
+in the seventeenth century to commemorate the interposition
+of Providence in staying one of the great epidemics
+of plague. Now that science has made known the true
+cause of plague, our ideas as to the causes of the appearance
+and disappearance of epidemics are very different. Plague
+is not the manifestation of the anger of God, but is a scourge
+due to invasion by a minute organism, discovered simultaneously
+by Kitasato and Yersin in 1894. The natural
+history of the microbe has been studied, and we know that
+it may live not only in human bodies but in the bodies of
+small rodents, such as rats and mice, which live in association
+with man. These animals are the source of human
+infection, and it is necessary to destroy them as completely
+as possible. There is no doubt but that the arrest of the
+plague in the seventeenth century was due to the fact that
+rats and mice had themselves been exterminated by the
+plague.</p>
+
+<p class='c007'>Plague, which formerly was the most terrible of epidemic
+diseases, has now become a misfortune against which it is
+simple to guard ourselves. To secure that end, however,
+we have not to pray or to scourge ourselves, but to take
+measures to destroy rats and mice. Moreover serums may
+be employed; and the use of these is not only prophylactic,
+but if the disease be not too advanced, is actually curative.
+The danger of which Schopenhauer spoke may be regarded
+as definitely averted, and this is due to the advance of
+medical knowledge. In such countries as British India in
+<span class='pageno' id='Page_209'>209</span>which plague still causes great losses, we have to blame
+the ignorance of the population. Instead of following
+the course prescribed by science, these people still prefer
+the rules laid down by the Brahmanistic religion. Their
+idea of cleanliness and purity is a religious idea, and not
+that of medicine and bacteriology. It is not surprising
+that plague still exists in India, but none the less no case
+is a better instance of the progress of knowledge.</p>
+
+<p class='c007'>Hartmann’s idea as to a progressive increase in the
+number of diseases rests on no exact grounds, and is in
+opposition to much that we know. As a matter of fact, as
+knowledge of hygiene advances and becomes spread among
+the peoples, diseases become less frequent and less fatal.</p>
+
+<p class='c007'>A great stimulus was given to medicine and surgery when
+there was applied to these the knowledge gained by Pasteur
+in his study of fermentation. Pasteur showed that fermentations
+were chemical alterations in organic matter, excited
+by the presence of minute organisms very common in the
+neighbourhood of man.</p>
+
+<p class='c007'>This discovery was applied in the first place to surgery.
+Lord Lister, then a surgeon in Scotland, showed that the
+festering of wounds was due to the entrance of minute
+organisms. Following this clue, he succeeded, by the use
+of dressings, in preventing the contamination of wounds
+and at once saw a vast reduction in deaths following surgical
+operations. Since the discovery of anæsthetics, such as
+ether, chloroform, and cocaine, and the use of germ-free
+dressings, surgery has been developed in a marvellous
+fashion. The varied and delicate feats of abdominal
+operation are known to all, and recently surgery of the
+heart has become possible.</p>
+
+<p class='c007'>A comparison of the mortality of the wounded in the
+different wars of the nineteenth century affords an excellent
+<span class='pageno' id='Page_210'>210</span>means of gauging the progress of surgical treatment of gunshot
+wounds. The mortality of the wounded among the
+English troops in the Crimean war reached 15.21 per cent.;
+in the French troops in Italy in 1859–1860, it was 17.36
+per cent.; in the German army in 1870–1871, the years
+in which antiseptic surgery came into use, it fell to 11.07
+per cent.; while in the Spanish-American war in 1898,
+in the most brilliant period of modern surgery, the percentage
+mortality of wounded had fallen to 6.64.<a id='r267'></a><a href='#f267' class='c014'><sup>[267]</sup></a> In the recent
+Transvaal war, the mortality was half what it had been
+in the Franco-German war.<a id='r268'></a><a href='#f268' class='c014'><sup>[268]</sup></a></p>
+
+<p class='c007'>New medical knowledge, founded on the discovery of
+the nature of ferments and of the virus of infection, has
+reformed the practice of midwifery to such an extent that
+puerperal fever, formerly one of the great scourges of
+humanity, is now extremely rare.</p>
+
+<p class='c007'>Blindness acquired at birth, which formerly rendered
+many lives extremely miserable, is now practically completely
+prevented, by means of the precautions taken to
+hinder the child from being contaminated by the mother
+in the process of birth. The most successful method is that
+which was suggested by Credé,<a id='r269'></a><a href='#f269' class='c014'><sup>[269]</sup></a> a German physician, and
+consists in placing in the pupils of the infant a minute drop
+of nitrate of silver, which is an antiseptic, and prevents
+the occurrence of ocular blennorrhagia.</p>
+
+<p class='c007'><span class='pageno' id='Page_211'>211</span>Appendicitis, a disease so common that I referred to it
+in chap. iv. as one of the most salient examples of disharmony
+in the human constitution, has been resolutely
+attacked by medical science. In some cases, surgical interference
+makes a definite end of the disease; in other
+cases medical treatment has been enough to subdue the
+symptoms without recourse to operation.</p>
+
+<p class='c007'>For a considerable period, those of a sceptical disposition
+asserted that the advance of bacteriological knowledge
+was of service only in surgical cases. But Pasteur showed
+that this was an erroneous view. Working with Chamberland
+and Roux, Pasteur demonstrated that many infectious
+diseases could be prevented by the use of attenuated virus;
+he succeeded in saving the lives of many animals and of
+men, bitten by rabid dogs and affected by hydrophobia,
+a disease formerly almost invariably fatal and among the
+most horrible to which man is liable.</p>
+
+<p class='c007'>In the latter direction, medical science is developing
+at an extraordinary rate, and is achieving results of a remarkable
+nature. Among recent discoveries, I may mention
+that of the curative properties of the blood serum of animals
+which have been subjected to the action either of microbes
+or of the soluble products of microbes. Von Behring,
+working with the Kitasato, a Japanese investigator, has
+shown that a serum of this nature, prepared with the poison
+produced by the microbe of diphtheria (the poison was
+discovered by Roux in collaboration with Yersin), is capable
+not only of protecting those in good health from diphtheria,
+but of curing those who have been attacked by the disease.
+The serum fails to act only when it is employed in advanced
+cases of diphtheria.</p>
+
+<p class='c007'>Anti-diphtheritic serum, introduced into medical practice
+about eight years ago, has been tried in every way and has
+<span class='pageno' id='Page_212'>212</span>been proved to possess both preventive and curative properties.
+If patients still die from diphtheria, it is only because
+the treatment has been applied too late or insufficiently.</p>
+
+<p class='c007'>The use of the anti-diphtheritic serum has reduced the
+mortality in cases of diphtheria from 50 or even 60 per
+cent. to 12 or 14 per cent. The number of infant lives
+that have been saved by this method must be enormous.</p>
+
+<p class='c007'>The beneficent discovery of the curative value of serums
+has been applied to other diseases and is giving very encouraging
+results. I cannot go into details here, but it is
+enough to say that in the last quarter of a century medicine
+has entered a new epoch, and has taken its place among
+other exact sciences based on the experimental method.
+Although it is not surprising that in so short a space of time
+science has not yet conquered all the ills affecting humanity,
+this failure has provoked the most severe criticism.</p>
+
+<p class='c007'>“Indeed,” one of the critics has said, “you vaunt the
+progress of medical science at a time when you have to
+confess that it has failed to cure tuberculosis, one of the
+gravest of the infectious diseases, which alone causes the
+death of a sixth part of the human race.” It is true that
+the infectious nature of this scourge was announced by
+Villemin more than forty years ago. Twenty years have
+passed since Koch, the German bacteriologist, discovered the
+microbe that produces not only the ordinary form of pulmonary
+consumption but all other varieties of tuberculosis.
+And we are still ignorant of any remedy for the disease.
+In all the bacteriological institutes and laboratories search
+is being made for some vaccine or serum or medicament
+which will arrest a disease that in many cases nature herself
+cures. But the results amount practically to nothing.</p>
+
+<p class='c007'>This is certainly a good example of the failure of science.
+None the less a closer examination shows that even with
+<span class='pageno' id='Page_213'>213</span>the knowledge already gained we could deal with tuberculosis
+in a manner more efficacious than is the existing practice.
+When the infectious nature of the disease had been
+made known, before waiting for the discovery by Koch
+of the actual bacillus, we should have employed all the
+known modes of destroying infectious matter. In spite
+of all that has been said and written on the subject, people
+still spit on the floors of omnibuses and cars and on street
+pavements. Tuberculosis is propagated not because of
+the failure of science, but because of the ignorance and
+stupidity of the population. To diminish the spread of
+tuberculosis, of typhoid fever, of dysentery, and of many
+other diseases, it is necessary only to follow the rules of
+scientific hygiene, without waiting for specific remedies.</p>
+
+<p class='c007'>Although the science of to-day is sufficiently armed
+against the diseases commonly known as infectious, the case
+is very different with some other affections, among which
+the chief place is taken by malignant tumours, or cancers,
+in the most general sense of the word.</p>
+
+<p class='c007'>There are few maladies more terrible, for they practically
+never disappear spontaneously, and surgery can
+remove them successfully only if they have been recognised
+at an early stage. Every year a number of persons, old
+and young, die victims of malignant tumours, and it is even
+possible that cancer is more prevalent now than in former
+times. It has been suggested that the increase of cancer
+is due to the greater longevity among modern races, and
+as malignant tumours are most common in old persons,
+it may well be that the prolongation of life has given this
+disease a larger field. However, even allowing for this,
+it is probable that there is a real increase of cancer.</p>
+
+<p class='c007'>Unquestionably the malignant tumours are the diseases
+most disappointing to medicine and surgery, and these
+<span class='pageno' id='Page_214'>214</span>sciences are as much at a loss with regard to them as in the
+case of infectious diseases before the discovery of pathogenic
+organisms. Science is perhaps even in worse case with
+regard to cancer than it formerly was with regard to infectious
+diseases, for, before the discovery of microbes, something
+was known of the virus which produces infection.
+Thus the virus of smallpox was known, and was used, by
+the method of inoculation, to prevent more serious attacks
+of the disease. Nearly a century before the discoveries
+of Pasteur, Jenner had been able to be of the greatest service
+to mankind by his discovery that the virus of cow-pox
+could be used as a preventive of infection by smallpox.</p>
+
+<p class='c007'>In the case of malignant tumours, we do not even know
+their real nature; we are ignorant as to whether or no they
+are infectious, and whether they are caused by a microbe
+coming from without or are due to internal changes of the
+tissues. Our ignorance, however, affords no ground for
+despair. It is probable that the malignant tumours will
+soon come to be ranged with infectious diseases due to
+invasions by specific microbes. Experiments on the cancers
+in rats and mice have shown that these can be inoculated
+in the same manner as in the case of the recognised infectious
+diseases. Hanau has shown that this occurs in the case
+of epithelioma of old rats; Morau<a id='r270'></a><a href='#f270' class='c014'><sup>[270]</sup></a> has succeeded in transferring
+the cancers of white mice, and his results have been
+confirmed by Jensen<a id='r271'></a><a href='#f271' class='c014'><sup>[271]</sup></a> and Borr<a id='r272'></a><a href='#f272' class='c014'><sup>[272]</sup></a>, in the Institut Pasteur.
+These investigations mark the beginning of a new stage in
+the knowledge of tumours. I am unable to see, therefore
+that the malignant tumours provide a satisfactory argument
+in favour of a pessimistic conception of the universe.</p>
+
+<p class='c007'><span class='pageno' id='Page_215'>215</span>Dr. Boas, of Berlin,<a id='r273'></a><a href='#f273' class='c014'><sup>[273]</sup></a> in a recent publication, has laid
+stress on the fact that most patients affected with cancer
+do not seek medical aid until the disease is far advanced.
+For instance, in 80 per cent. of the cases of cancer of the
+rectum that he had attended, the patients presented themselves
+too late for operation. Boas advised that the attention
+of the public should be drawn, by means of widespread
+publication, to the earliest symptoms of cancerous disease.
+He thought that such a course might save many lives by
+making possible operation in early stages.</p>
+
+<p class='c007'>The prevention and treatment of disease, which for long
+was in the hands of religious authorities, is now passing
+into the care of those who employ the methods of scientific
+medicine. It is now only in the case of certain nervous
+maladies, which can be treated by suggestion, that religion
+has any important part to play. I have not thought it
+necessary to expound at length the work of science in the
+struggle against disease, because the evidence on this point
+is extremely clear and precise. Every one must accept it,
+and even the passionate enemies of science have to bow
+before the fact.</p>
+
+<p class='c007'>However, the problem has been changed. Science they
+now admit, is capable, no doubt, of assuaging humanity
+in its sufferings from this or the other disease. But there
+is another question. Disease is only an episode in human
+life, and the great problems remain unsolved by science.
+It is not enough to cure a man of diphtheria or intermittent
+fever; it is necessary to explain what the destiny of man
+is, and why he must grow old and die at a time when his
+desire to live is strongest. Here, plainly, all science must
+fail, and here must begin the beneficent work of religion
+and philosophy. But as science is constantly casting doubt
+<span class='pageno' id='Page_216'>216</span>on the dogmas of religion, and criticising adversely the
+systems of philosophy, it is plain, that so far from being
+of service, science is actually harmful to mankind.</p>
+
+<p class='c007'>The campaign against science was opened long ago. In
+the eighteenth century Rousseau<a id='r274'></a><a href='#f274' class='c014'><sup>[274]</sup></a> opened it with brilliancy
+and zest worthy of his reputation. He defended his theme
+with vigour and eloquence and the following quotations
+may serve as an example, “Know O people,” he wrote,
+“that nature has desired to preserve you from science as
+a mother tries to snatch a dangerous weapon from the
+hands of her child; that the secrets which she has hidden
+from you are evils from which she would preserve you, and
+that one of her greatest gifts is the difficulty with which
+knowledge is acquired. Human beings are perverse, but
+they would have been worse had they had the misfortune
+to be born learned men.<a id='r275'></a><a href='#f275' class='c014'><sup>[275]</sup></a> Our sciences are futile in so far
+as they fail to attain their objects, but they are worse than
+futile in the results that they bring about. Born of idleness,
+they cherish their mother—Tell me, illustrious philosophers,
+you from whom we know why matter attracts
+matter, the relations of the orbits traced by revolving
+planets, the mathematical properties of curves, what stars
+may be inhabited, what insects exhibit curious modes of
+reproduction; tell me, I say, you from whom we have gained
+such marvellous information, if you had never learned of
+these things, should we have been less numerous, less well
+governed, less flourishing, or worse disposed?”<a id='r276'></a><a href='#f276' class='c014'><sup>[276]</sup></a></p>
+
+<p class='c007'>Such words were capable of impressing men because of
+their eloquence and sincerity, but they could not arrest
+the continued and triumphant advance of science, which
+<span class='pageno' id='Page_217'>217</span>indeed, precisely at the end of the eighteenth century,
+began its modern and lasting progress. For it was then
+that Laplace described the system of the heavens and that
+Lavoisier laid the foundation of modern chemistry and of
+our knowledge of the indestructibility of matter.</p>
+
+<p class='c007'>In the nineteenth century, science has made a revolution
+in life by its application of steam and by its other triumphs.
+None the less it has not satisfied many distinguished persons.
+And to-day we find a writer of genius, in the manner of
+Rousseau, raising his voice against the science of the nineteenth
+century.</p>
+
+<p class='c007'>Tolstoi, in an essay of which the title is, “On the Aim of
+Science and Art,” has attempted to show the incompetence
+of science with regard to the great problems that occupy
+humanity. The task set himself by the Russian writer
+was much harder than that of Rousseau, for with the passing
+of a century science has become much more powerful.</p>
+
+<p class='c007'>Tolstoi is convinced that theoretical investigations into
+the origin of life, the intimate structure of living matter
+and so forth, are of no importance to human beings, and
+serve no other purpose than to flatter the pretensions of
+the learned. “All that we call culture,” he affirmed,
+“our sciences, our arts, improvements in the amenity of
+life, are no other than attempts to deceive the moral
+cravings of mankind; all that we call hygiene and medicine
+are no other than attempts to deceive the physical and
+natural cravings of mankind.”<a id='r277'></a><a href='#f277' class='c014'><sup>[277]</sup></a></p>
+
+<p class='c007'>The whole progress of science “up to the present time,
+has not only not improved the lot of the majority of mankind,
+that is to say of the labourers, but has made it worse.”<a id='r278'></a><a href='#f278' class='c014'><sup>[278]</sup></a></p>
+
+<p class='c007'>Tolstoi thinks that the epithet “true science” could be
+given only to “knowledge of the right aim and true
+<span class='pageno' id='Page_218'>218</span>happiness of each individual and of mankind as a whole.
+Such a science would serve as a guiding thread in determining
+the proper sphere of all knowledge”; “without knowledge
+of the proper aim of life and of the real good of humanity,
+all other knowledge and every art become merely amusements
+idle or even harmful.”<a id='r279'></a><a href='#f279' class='c014'><sup>[279]</sup></a></p>
+
+<p class='c007'>The chief grievance of the great Russian writer against
+knowledge, culture, and progress can be resolved into the
+powerlessness of these to explain the most difficult problems
+of humanity, that is to say the real aim of human life, and
+what really constitutes true happiness.</p>
+
+<p class='c007'>In this connection, Tolstoi gives expression to a view
+which is shared by many thinkers. Some years later,
+Brunetière,<a id='r280'></a><a href='#f280' class='c014'><sup>[280]</sup></a> a well-known French writer and public man,
+under the influence of a recent journey to Rome and visit
+to the Pope, made public a similar opinion, and proclaimed
+aloud the fallibility of science.</p>
+
+<p class='c007'>Brunetière made his criticism as follows: “For the last
+two or three centuries, science has promised to change the
+face of the earth, to dispel every mystery; she has not done
+so. She is powerless to resolve the sole problems that are
+essential, that concern the origin of man, the rules for his
+conduct, and his future destiny. We know now that
+natural science can teach us none of these matters. Thus,
+in the battle between science and religion, science has been
+defeated, because she has had to admit her powerlessness
+precisely where religion is most strong. For religion gives
+the solutions that science has failed to supply. Religion
+teaches us what we can learn neither from anatomy nor from
+physiology, that is to say, what we are, whither we are
+<span class='pageno' id='Page_219'>219</span>going, and how we ought to act. Religion and science
+supplement each other; and, as science can do nothing
+for morality, it becomes the duty of religion to take her
+place.”</p>
+
+<p class='c007'>It has been replied to Brunetière, that his recriminations
+are unfounded, first, because science has never undertaken
+to solve the great problems of the aim of life and the proper
+basis of morality; next, because it is probable that these
+problems will never be solved by the human understanding.
+Charles Richet, a well-known French physiologist, made
+a vain effort to find any written evidence that science had
+promised to solve the great problems which have absorbed
+the attention of Tolstoi and Brunetière as well as of quite
+a large section of humanity. “In what standard works
+has science made the astonishing promises that M. Brunetière
+recalls with so much bitterness?” asked Richet.<a id='r281'></a><a href='#f281' class='c014'><sup>[281]</sup></a>
+“I have now before me,” he proceeded, “the Manuel du
+baccalauréat ès sciences (Guide to a Degree in Science).
+It is a summary of contemporary scientific ideas. I have
+looked through it in vain for promises—it contains no
+promises.”<a id='r282'></a><a href='#f282' class='c014'><sup>[282]</sup></a></p>
+
+<p class='c007'>The promises referred to must be looked for in scientific
+treatises that deal in generalisations. It is not to be disputed
+that, since the renaissance in Europe of the rational
+and sceptical spirit, that is to say, in the last two or three
+centuries, the view has been proclaimed that all human life
+may be regulated by natural laws without the interposition
+of dogmas, either metaphysical or religious. Attempts
+of this kind have been numerous. Büchner, in his treatise
+on “Force and Matter,” in which he tried to give a general
+conception of the universe based on the scientific knowledge
+of the nineteenth century, made very plain statements on
+<span class='pageno' id='Page_220'>220</span>this point. “We must seek the foundation of morality,”
+said the German populariser, “elsewhere than in the timeworn
+and fantastic belief in the supernatural. Science
+must replace religion; belief in the real existence of a
+natural and immutable order in things must displace belief
+in spirits and ghosts; natural moral law must take the
+place of artificial or dogmatic morality.”<a id='r283'></a><a href='#f283' class='c014'><sup>[283]</sup></a> Büchner even
+tried to indicate what natural morality is. According to
+him it is “the law of mutual consideration of the equal rights
+of each person, both from the general and the individual
+point of view, so as to assure the greatest happiness of the
+greatest number. Everything that damages or destroys
+the common good is ‘evil;’ everything that favours it is
+‘good.’”</p>
+
+<p class='c007'>The other question, as to whither we are going, finds an
+answer in the materialistic and scientific breviary of Büchner.
+He disputes the idea of immortality, which has been supported
+by nearly all the religions, and comes to the conclusion
+that there is nothing appalling to a man, “imbued
+with the principles of philosophy, in the conception of the
+annihilation of the individual life.” “Annihilation is perfect
+rest; it is freedom from all pain and escape from the sensations
+that torture the body and the mind—as was explained
+so clearly in the great religion of Buddha; it is
+not to be feared, but rather to be coveted when life has
+reached its normal term and when old age has come with
+its inevitable assemblage of infirmities.”</p>
+
+<p class='c007'>I do not wish to suggest that the views I have just quoted
+are peculiar to Büchner. That writer has served to a large
+extent as the mouthpiece of ideas current among the
+materialistic and positivist men of science of his time.
+In Haeckel’s book, “The Riddle of the Universe,” which
+<span class='pageno' id='Page_221'>221</span>appeared nearly half a century after the first edition of
+“Force and Matter,” the same ideas are to be found. He
+also has found answers to the questions that absorb mankind.
+In his opinion also, as I have shown in chap. v.
+the problem of natural morality resolves itself into the
+social instincts of man, and has nothing to do with religious
+dogma. As for the destiny of man, he concludes as
+follows: “The best end we can desire after a courageous life,
+spent in doing good according to our light, is the eternal
+peace of the grave.”<a id='r284'></a><a href='#f284' class='c014'><sup>[284]</sup></a></p>
+
+<p class='c007'>There is a very close resemblance between the views of
+the two great popularisers of the nineteenth century. Just
+as Büchner, to show the stupidity of the idea of eternal life,
+repeated the legend of the “Wandering Jew,” so Haeckel,
+with the same object, related the legend of the unhappy
+“Ahasuerus” who sought death vainly, finding his eternal
+life intolerable. “However gloriously we may depict this
+eternal life in paradise, in the end it would be a fearful
+burden to the best of men.”</p>
+
+<p class='c007'>While there is no doubt but that such ideas are shared
+by many men who rely on scientific arguments, there are
+others to whom the problem presents itself differently.
+The German physiologist, Du Bois Reymond, after reflecting
+on the general problems of knowledge and the universe,
+proclaimed an “Ignorabimus” as a warning that a whole
+series of problems of the highest importance to humanity
+were outside the range of human knowledge and incapable
+of solution. These problems were precisely the seven
+“riddles of the universe” that Haeckel claimed to have
+solved in his book.</p>
+
+<p class='c007'>Many learned men think that the great problems, those,
+according to Tolstoi, that constitute the only true science,
+<span class='pageno' id='Page_222'>222</span>can never be solved. “Every day there comes a new
+conquest,” said Richet,<a id='r285'></a><a href='#f285' class='c014'><sup>[285]</sup></a> “but we are no nearer solution
+of the ultimate enigma, the destiny of human life, an enigma
+probably never to be solved.” Philosophers have taken
+the same view. “It cannot be from science,” said Guyau,
+“that personality is to require the proofs of its own durability.”<a id='r286'></a><a href='#f286' class='c014'><sup>[286]</sup></a></p>
+
+<p class='c007'>The answers given by science as it exists to-day, have
+failed to console the spirits that have applied to her. When
+Richet, in the discussion on the “bankruptcy of science”
+recalled the discovery of treatment of diphtheria by specific
+serums as an instance of the value of scientific research,
+Brunetière replied, “Serum therapy cannot prevent us
+from dying, nor tell us why we must die.” The problem of
+death always recurs. What is the use of saving the life
+of a child smitten by diphtheria only that it may grow up,
+and by learning the inevitability of death become filled with
+terror?</p>
+
+<p class='c007'>If science be really powerless before the gravest problems
+that torture mankind, if she has to excuse herself by admitting
+her incompetence, if she can do no better than to extol
+the silent annihilation of the grave, it is not surprising that
+many minds and these not the least capable, turn from
+her. The desire to find some consolation in the miseries
+of a purposeless existence throws them into the arms of
+religion or metaphysics. Here lies the explanation of the
+actual return in these days to faith. People plunge into
+mysticism hoping to find there something more comforting
+than the annihilation offered by science.</p>
+
+<p class='c007'>In all ranks of modern society there are signs of this
+craving for the supernatural. It is therefore extremely
+interesting to follow the intimate steps of such an
+<span class='pageno' id='Page_223'>223</span>abandonment of science and return to faith. The
+“Confessions” of Tolstoi gave one of the best examples of
+the metamorphosis.</p>
+
+<p class='c007'>Having reached the conclusion that life is meaningless
+because it cannot be harmonised with the fear of death and
+the prospect of absolute annihilation, Tolstoi (see chap.
+vi.) asked if it were not possible to solve the great problem
+of human existence by means of the facts of science. “I
+searched in all the sciences,” he said, “and not only found
+nothing myself, but became convinced that all who sought
+would find nothing. Not only would they find nothing,
+but they would see clearly precisely what had driven me
+to despair, the fact that the absurdity of life is the sole
+indisputable bit of knowledge open to man.” “For a long
+time, observing the grave and solemn tones of the exact
+sciences, which indeed, hardly touched the problem of life,
+it seemed to me that they must be concealing something
+that I did not understand.”</p>
+
+<p class='c007'>All the while, the question that Tolstoi put to himself
+seemed simple enough: “Why am I to keep alive? Why
+am I to do anything?” or, in another way: “Has life any
+object that is not destroyed by the inevitable death that
+awaits me? To the one question, put in many ways, I
+sought an answer in human knowledge.” “From my
+earliest youth the speculative sciences interested me deeply.
+Later on, the mathematical and physical sciences attracted
+me, and until my question rose up clearly before me, day
+by day growing larger, and imperatively demanding an
+answer, until then I was satisfied with the semblance of
+an answer given by science.” “I said to myself; everything
+is evolving, differentiating, moving towards complexity
+and amelioration, and the progress is under the
+guidance of law. You, you yourself are part of this whole.”
+<span class='pageno' id='Page_224'>224</span>“Although I am deeply ashamed to confess it, there was
+a time when I thought myself content with these things.
+My muscles grew and became stronger. My memory added
+to its stores. My ability for thinking and understanding
+increased. I grew and developed, and feeling the growth
+within me, it seemed natural to believe that the solution
+of my own life was given by the law of the whole universe.
+But the time came when I stopped growing. I felt that I
+was no longer developing and even that I was slipping back.
+My muscles weakened; my teeth dropped out; and I felt
+that this law not only explained nothing, not only had never
+explained anything, but had not been a law at all; that in
+fact I had taken for a law what I found in myself at a
+particular stage of my life.”</p>
+
+<p class='c007'>“As I found no explanation in science,” Tolstoi went
+on, in his poignant narrative, “I began to look for the
+answer in life, hoping to find it in the men around me.”
+“My intellect was at work, but also something else, something
+that I can call only the consciousness of life, like some
+strong force that compelled my intellect to turn in another
+direction and to rescue me from my desperate condition.”</p>
+
+<p class='c007'>The new direction was the feeling of faith. “However
+I might put to myself the question: how must I live?
+the answer was—by the law of God. Whither tends my
+present life? To eternal pain or to blessedness everlasting.
+How is my life not destroyed by death? By eternal union
+with God, by heaven. And thus I was led inevitably to
+see that quite independently of human knowledge, which
+formerly seemed to me the only guide, mankind had another
+guide, a guide that is irrational; faith which makes life
+possible. Faith seemed to be as irrational as ever, but I could
+not but recognise that faith alone gave mankind an answer
+to the problem of life, and in consequence made life possible.
+<span class='pageno' id='Page_225'>225</span>Reason had led me to the conviction that life was absurd,
+and so, there being no longer a reason to live, I had wished
+to kill myself. Looking at mankind as a whole, I saw that
+men kept alive by assuring themselves that they saw a
+meaning in life. I myself came back to that point of view.
+I had reached a time when there seemed to me to be no
+meaning in life. But as to other men, so to me, life and the
+possibility of living were offered by faith.”</p>
+
+<p class='c007'>Driven in the direction of faith, Tolstoi reached the
+following conclusion: “The object of a man’s life is the
+salvation of his soul; for that, we must live in God, and to
+live in God it is necessary to give up the pleasures of life,
+to work, to submit, to suffer and to be charitable.” And
+this conclusion led to the other that “a faith has value in
+so far as it gives a meaning to life which is not destroyed
+by death.”</p>
+
+<p class='c007'>It is plain then that all this evolution, the beginning of
+which was the fear of death, ended in belief in something
+beyond death. And it is also plain why Tolstoi should
+have been as bitter against science as I have shown him to
+be. Tolstoi does not afford the only example of a case
+where the failure of science to solve the problem of death
+has led to the abandonment of science in favour of religion.
+Brunetière, if it is possible to judge from his published
+writings, traversed similar paths in his journey to the
+Catholic religion.</p>
+
+<p class='c007'>However, even an intellect so positive and so sceptical
+as that of Zola has been unable to resist the lures of faith.
+There is a very interesting note on this subject in the <cite>Journal</cite>
+of de Goncourt, dated February 20, 1883. “To-night,
+after dinner, at the foot of the bedstead of carved wood,
+where coffee was served, Zola began to talk of death, on
+which his thoughts have been fixed more than ever since
+<span class='pageno' id='Page_226'>226</span>the death of his mother. After a short silence, he said
+that death had made an in-road on the nihilism of his
+religious convictions, as he could not face the possibility
+of an eternal separation.”</p>
+
+<p class='c007'>In strata of society less impregnated with rational and
+scientific thought, it is plain that the return to religion
+must be more common. I recall the case of a woman of
+the people, a workwoman, who declared that she formerly
+had had no belief, but that, since the birth of her son, she
+had begun to believe in the good God, as she was convinced
+that it was only by such a belief that she could guard the
+life of her child from the evils of the world.</p>
+
+<p class='c007'>As things are, it is not wonderful that many people
+decline to educate their children in an exclusively scientific
+spirit, which is destructive to faith, as they cannot substitute
+for faith something equally consoling. Perhaps ideas of
+this kind lie behind the story of the apple of the Garden
+of Eden and the invention of the words of Jahveh: “But
+of the tree of the knowledge of good and evil, thou shalt
+not eat of it: for in the day that thou eatest thereof thou
+shalt surely die” (Genesis ii. 17). The legend of Prometheus,
+who stole fire from heaven, and was chained to a
+rock, is in the same category.</p>
+
+<p class='c007'>Solomon gave voice to the same idea, in the clearest way,
+in his words: “I communed with mine own heart, saying,
+Lo, I am come to great estate, and have gotten more wisdom
+than all they that have been before me in Jerusalem; yea,
+my heart had great experience of wisdom and knowledge.</p>
+
+<p class='c007'>“And I gave my heart to know wisdom, and to know madness
+and folly: I perceived that this also is vexation of
+spirit.</p>
+
+<p class='c007'>“For in much wisdom is much grief: and he that increaseth
+knowledge, increaseth sorrow” (Ecclesiastes, i. 16).</p>
+
+<p class='c007'><span class='pageno' id='Page_227'>227</span>Much later, Shakespeare offered to us in <em>Hamlet</em>, the
+type of a man very highly cultivated, in whom reason and
+reflection had arrested action. As he could not solve by
+reason the problems that haunted him, he asked if it were
+worth while to remain alive. Then followed the famous
+lines:</p>

+<p class='c007'>As so many men of genius have taken the same point
+of view, it becomes necessary to inquire carefully as to
+whether or no too much knowledge be harmful to human
+happiness. If science do no more than to destroy faith and
+to teach us that the whole living world is moving towards
+a knowledge of inevitable old age and death, it becomes
+necessary to ask if the perilous march of science should
+not be stayed. Is it that the attraction of mankind to
+knowledge is as dangerous to the race, as the attraction
+of moths to the light is fatal to these wretched insects?
+The question demands an exact answer. But before giving
+the verdict, the facts of the case must be examined. I
+shall proceed to this in the chapters to follow.</p>

+
+<p class='c006'>While I cannot share the views of those who turn from
+science to seek truth and consolation in religion, it would
+be wrong to ignore or to be indifferent to the existence of
+that attitude. There are men who are tormented by the
+contradiction between the desire of life and the inevitability
+of death, and when these demand some solution of the problem,
+it is unreasonable merely to say that they are too
+exacting and should learn contentment.</p>
+
+<p class='c007'>If a man complains to his physician of uncontrollable
+hunger and thirst, he is not told that it is wrong to be so
+greedy, and that that fault could be mastered by strength
+of mind. The doctor carefully examines the patient and
+does what he can for the distressing symptoms, which,
+indeed, in this case are generally due to diabetes. Those who
+<span class='pageno' id='Page_229'>229</span>hunger and thirst after eternal life, ought to be similarly
+treated by men of science whose duty it is to ameliorate
+their sufferings as much as possible.</p>
+
+<p class='c007'>Science has undoubtedly gone far in the successful treatment
+of disease, both as regards prevention and cure, but
+it is powerless before those other evils from which Buddha
+implored his father to grant him exemption—old age and
+death. Science has attained to heights of knowledge
+undreamed of by Buddha’s father, King Couddhôdana,
+and yet it knows no more than he did with regard to the
+problem of old age and death. Like the king, science can
+but reply to its questioners: “You ask the impossible.
+I cannot help you!”</p>
+
+<p class='c007'>Not only is no remedy for old age known to science,
+but little or nothing is known with regard to that period
+in the lives of men and animals. It was no easy task to
+compress an account of the present position of medicine
+within a few pages, the subject matter being overwhelming
+in quantity. With regard to old age it is quite the contrary,
+our knowledge being so limited that the subject may be
+dealt with in a few lines. With the advance of years, man
+and the higher animals undergo important modifications.
+They become weaker, the body shrinks, the hair whitens,
+and the teeth decay; in fact, all the phenomena connected
+with senile decay manifest themselves.</p>
+
+<p class='c007'>At this period of life which overtakes various species
+of animals at different ages, the body becomes an easy
+prey to pernicious influences and diseases. The direct cause
+of death cannot always be determined, and is attributed
+to the general breaking up of the system which we call
+natural death. The first question which presents itself
+to the scientific mind is whether this degeneration or senile
+decay is proper only to man and the higher animals, or is
+<span class='pageno' id='Page_230'>230</span>common to all forms of life. We have all seen very old
+trees, the appearance of which proclaims their age. The
+trunk is decayed, the bark gnarled, the branches shrivelled,
+and the leaves scanty. Some kinds of trees live for hundreds—possibly
+thousands—of years, while others age with
+comparative rapidity. Senile decay is not
+unknown in the vegetable kingdom, and its
+presence is suspected even among creatures
+of very simple organisation belonging to
+the group of infusoria. These creatures
+may be reared with ease in vessels containing
+macerations of chopped hay or
+leaves. They multiply by means of division
+(Fig. 12), an operation which takes
+place at very short intervals, some of
+them dividing nearly every hour. Owing
+to this rapid multiplication the vessels
+soon become full of a mass of infusoria.
+M. Maupas,<a id='r287'></a><a href='#f287' class='c014'><sup>[287]</sup></a> a very distinguished zoologist,
+observed that the infusoria became
+smaller and smaller after a number of
+generations, exhausting themselves, as it
+were, and perishing unless two individuals succeed in
+uniting. This process of “conjugation” (Fig. 13), involves
+an exchange of portions of the bodies of the two creatures
+and brings about a complete rejuvenescence of the two
+individuals. After conjugation, a process essentially similar
+to the details of sexual fertilisation, the infusoria resume
+the normal appearance and again become capable of reproduction
+by simple division for many generations.</p>

+</div>
+</div>
+
+<p class='c007'>The periodical debility, which precedes conjugation is,
+<span class='pageno' id='Page_231'>231</span>according to Maupas, an instance of senile degeneration
+among infusoria. He has recognised its existence in the
+case of many species of the higher infusoria (<em>Ciliata</em>), but
+while this phenomenon has been observed in the case of
+many other simple organisms, it cannot be set down as
+universal among microscopic beings. Among bacteria, a
+group that includes the greater number of pathogenic organisms,
+conjugation has been very
+rarely observed. Even the largest
+kinds, such as, for instance, the
+<em>anthrax</em> bacillus, may be propagated
+for a long series of generations
+without the occurrence of
+conjugation.</p>
+
+<div  class='figright id003'>

+<div class='ic001'>
+<p><span class='sc'>Fig. 13.</span> Conjugation of two Paramecia (after Bütschli).</p>
+</div>
+</div>
+
+<p class='c007'>Even in the case of the infusoria
+which by means of the process of
+conjugation can reproduce indefinitely,
+the preconjugal debility
+cannot be identified with the senile
+degeneration of human beings, the
+higher animals and trees. In all
+these debility is the antecedent, not of conjugation and
+rejuvenescence, but of the end of life.</p>
+
+<p class='c007'>Another important difference is that in the case of infusoria
+the preconjugal debility does not occur in every
+individual, as is the case with the animals and plants which
+display real old age. In the infusoria an indefinite number
+of generations occur between the individuals that display
+debility and those that are ready for conjugation.</p>
+
+<p class='c007'>If, in spite of these differences, we were to insist on the
+existence of an essential resemblance between senile degeneration
+in man and preconjugal debility in infusoria, it
+would be enough to reflect on the result of applying to the
+<span class='pageno' id='Page_232'>232</span>case of man what is an infallible remedy in the case of the
+infusoria. For conjugation brings about a real rejuvenescence
+of the infusoria and a similar event in the case
+of man would only increase the debility. Moreover,
+according to recent investigations of Calkins,<a id='r288'></a><a href='#f288' class='c014'><sup>[288]</sup></a> infusoria,
+weakened by degeneration, may become young again not
+only by conjugating with their kind, but by the addition
+of bouillon or extract of brain to the medium in which
+they live.</p>
+
+<p class='c007'>Real old age is a phase of existence in which the natural
+forces abate never to be renewed. In animals, the life
+cycle of which is very definite, the signs of senile degeneration
+are not visible. Insects, in the adult condition, very
+often live only a short time, and die without displaying the
+slightest mark of age. In the case of lower vertebrates,
+old age is little known, and has few signs. On the other
+hand, mammals and birds display senile atrophy in a
+marked fashion.</p>
+
+<p class='c007'>Some species of birds live to a great age, longevity being
+more common than among mammals. Cases in which birds
+such as geese, swans, ravens, and some birds of prey, have
+been known to reach the age of fifty years,<a id='r289'></a><a href='#f289' class='c014'><sup>[289]</sup></a> are not uncommon,
+whereas such an event is very rare in the case of a mammal.
+Even small birds, such as canaries, may live as long
+as twenty years. Parrots are especially long-lived birds.
+Cockatoos have been known to reach the age of eighty
+years and more. I myself have had opportunities of observing
+a South American parakeet (<em>Chrysotis amazonica</em>) which
+lived more than eighty-two years, longer than is usual even
+<span class='pageno' id='Page_233'>233</span>with parrakeets. Several years before it died the bird
+showed unmistakable signs of old age. It became less
+lively, its plumage, although it did not whiten, lost much
+of its brightness, and the joints of the claws showed evidence
+of the presence of disease. In short, the parrakeet was
+obviously worn out and debilitated.</p>
+
+<p class='c007'>Mammals show the signs of age even more plainly than
+do birds. A dog reveals old age by its slow movements,
+its white hairs, and worn teeth. The appearance of such
+an animal is never agreeable, while it is often dirty and ill-tempered.
+Brehm describes the old age of a dog as follows:
+“At twelve years of age a dog has grown old, and his gait
+and whole organisation show signs of age. The coat is no
+longer glossy; the forehead and muzzle are grey, the teeth
+are blunted or have fallen out. The animal is lazy and
+apathetic. Many such dogs are dumb and blind. Dogs
+may live for twenty, six and twenty, or even thirty years,
+but such cases are most unusual.”</p>
+
+<p class='c007'>As the dog is a domesticated animal, it might be argued
+that its old age, with its manifest signs of decrepitude, is
+the result of the artificial conditions of its life. To decide
+on this point it is necessary to examine an instance of old
+age in a wild animal. This presents certain difficulties since
+wild animals when old and feeble become an easy prey to
+carnivorous enemies. It will best serve our present purpose
+to consider such information as has been collected regarding
+the period of old age in anthropoid apes.</p>
+
+<p class='c007'>The natives of Borneo have observed “old orangs, which
+have not only lost their teeth, but being too feeble to climb,
+live on the fallen fruits and herbs.”<a id='r290'></a><a href='#f290' class='c014'><sup>[290]</sup></a> Gorillas, according
+to Savage, turn grey in their old age, from which has arisen
+the erroneous view that there are two species of the gorilla.</p>
+
+<p class='c007'><span class='pageno' id='Page_234'>234</span>In their wild state, monkeys, like ourselves, are subject
+in their old age to various distressing ailments. Senile
+degeneration, then, which is universally looked upon as
+one of the greatest evils of life, is by no means restricted
+to the human race. Old age, as portrayed in the Buddhist
+legend, referred to in chap. vi., is perhaps somewhat
+exaggerated, but this period of life is undoubtedly characterised
+by changes of such a nature as considerably to
+affect the happiness of the old. Buddha, being a pessimist,
+took too dark a view of this, but let us hear what optimists
+have to say on the subject. Max Nordau, a doctor, a
+writer of books and a journalist, says: “Physically speaking,
+an old man presents an unpleasant picture of decrepitude
+to the casual observer. Morally speaking, he is a blind
+and pitiless egotist, having lost all interest in anything
+outside himself. Intellectually he becomes feeble-minded
+and narrow in his views, being governed by antiquated
+notions and prejudices, and incapable of grasping new
+ideas.”<a id='r291'></a><a href='#f291' class='c014'><sup>[291]</sup></a></p>
+
+<p class='c007'>It may be objected that I am here supporting my argument
+by quoting from a writer who, in his capacity of
+clever journalist, rather forces the note. Let me therefore
+refer to what a learned physiologist said when addressing
+a serious audience assembled for the purpose of obtaining
+truth and information from his lips. After dealing in broad
+outline with the physical degeneracy caused by old age,
+Longet<a id='r292'></a><a href='#f292' class='c014'><sup>[292]</sup></a> draws the following mental picture: “The old
+feel that their task in life is accomplished, and believe themselves
+to be universally grudged the space they occupy in
+the world. This renders them suspicious of all around
+them, and jealous of the young. Their craving for solitude
+<span class='pageno' id='Page_235'>235</span>and the uncertainty of their tempers are due to the same
+cause. All old people are not like this, of course. The
+hearts of some remain youthful and beat strongly within
+their feeble frames, but, as a general rule, they are morose
+and a nuisance to themselves and others, excepting when
+they are surrounded by their children or grandchildren,
+who like to listen to them about the past, and who make
+excuses for the present. Thus the years speed onward,
+every round of the clock bringing the end nearer, and every
+hour adding a new wrinkle to their faces, some fresh weakness
+and some new regret. Their bodies&#160;... become
+decrepit; their backbones, too weak to hold them upright,
+curve over and bend them downwards towards the earth.”</p>
+
+<p class='c007'>There can be no doubt but that the period of old age is
+sad, and a thorough knowledge of it is necessary before it
+can be understood. Disease can only be successfully dealt
+with when the cause of its presence is known, and so it is
+with old age.</p>
+
+<p class='c007'>Is it possible, one might ask, at the present stage of the
+world’s knowledge, to define, with even approximate accuracy,
+the characteristic features of senile decay? The task
+is difficult, for although the subject is very important, few
+facts have been collected.</p>
+
+<p class='c007'>It is common knowledge that the flesh of old animals,
+used as food, is tough. An old fowl cannot be compared
+with a tender and juicy chicken. Organs such as the liver
+and kidneys are much harder in the case of old animals.
+The horny flesh of old animals is often compared with
+boot-leather. Although the comparison does not pretend
+to be scientific, it is far from being incorrect. Boot-leather
+is made from the hides of animals; that is to say, of a very
+resistant material that is called “connective tissue,” and
+which consists of a dense mass of fibres, mingled with the
+<span class='pageno' id='Page_236'>236</span>living elements or “connective tissue” cells. This tissue
+is very durable and so is employed for boots and shoes.</p>
+
+<p class='c007'>The infiltration of any organ with connective tissue makes
+it tough and unpalatable. This hardening is called a
+<em>sclerosis</em> (of the liver, kidneys, &#38;c.). In old age many
+organs exhibit this tendency to hardening or sclerotic degeneration.
+The fact has been known for long, but its significance
+has been perceived more recently. Demange,<a id='r293'></a><a href='#f293' class='c014'><sup>[293]</sup></a> in
+his monograph on the organic changes associated with old
+age, states as follows: “Besides atrophy and degeneration
+of the parenchymatous elements,<a id='r294'></a><a href='#f294' class='c014'><sup>[294]</sup></a> there is to be observed
+a profound change in the framework of connective tissue,
+which serves to support the organs. In some cases the
+skeletal framework of an organ becomes more conspicuous,
+simply on account of the degeneration of the cells; this is
+the condition usually present in the liver of aged persons.
+More often, however, the connective tissue receives some
+kind of stimulation, which, although it does not amount to
+inflammation, brings about an active growth and resulting
+sclerosis. According to the particular case, the hardening
+occurs in the form of isolated patches or strands, or affects
+the whole periphery or even the depths of the organ, and
+smothers the higher elements in its meshes, so producing
+a further degeneration. The cellular elements disappear
+gradually, connective tissue taking their place, and the
+change may be so profound, that as in the case of the prostate
+gland, the altered organ may actually transcend the
+normal size, partial or general atrophy, however, being more
+often the result.”</p>
+
+<p class='c007'><span class='pageno' id='Page_237'>237</span>Sclerosis in old people sometimes takes the form of a
+hardening of the liver (cirrhosis of the liver) or of the kidneys
+(renal cirrhosis), but it is the arteries which are most commonly
+affected by it, producing a symptom of degeneration
+which is called arterial sclerosis.</p>
+
+<p class='c007'>Cazalis long ago originated the oft-repeated aphorism:
+“A man is as old as his arteries,” these vessels, by means
+of which the blood is distributed throughout the whole
+system, being of immense importance in the economy of
+the organism. When the connective tissue is so freely
+developed as to cause a hardening of the arteries, these are
+hampered in the exercise of their function and become very
+brittle. According to Demange, all the special modifications
+undergone by the body during the period of old age
+may be attributed to this atrophy of the arteries, but this
+theory is proved to be an exaggeration by the fact that
+post mortems on the aged frequently reveal the presence of
+little or no arterial sclerosis.</p>
+
+<p class='c007'>It might fairly be supposed that the hardening seen in
+many organs of the body during the period of old age is
+universal, and lends greater strength to the frame. The
+bones, which are separated from one another in youth,
+become welded together in old age owing to the calcareous
+deposits in the joints, and the ossification of the joints
+between the vertebra frequently causes the backbone to
+assume the appearance of a continuous bone, the greater
+part of the cartilage having become ossified. In spite of
+this, and as though for the purpose of proving how physically
+full of contradictions is the period of old age, the
+human frame actually becomes lighter and the quantity of
+component mineral substances becomes less. This brings
+about a liability to fracture of the bones in old people.
+The fracture of the neck of the femur is a constant cause of
+<span class='pageno' id='Page_238'>238</span>death in the aged, as occurred for instance in the case of
+Virchow, one of the most distinguished medical scientists
+of the nineteenth century.</p>
+
+<p class='c007'>Is science, it may be asked, in a position to state precisely
+what are the principal modifications which occur in the
+tissues of old people? At the International Congress of
+Medicine held at Berlin in 1890, a well-known German
+anatomist, Merkel,<a id='r295'></a><a href='#f295' class='c014'><sup>[295]</sup></a> attempted to reply to this question.
+Speaking of the tissues of old people, he tried to show that
+certain of these, such as the skin and the mucous membrane
+(the epithelial tissues), preserve their youthful characters
+to the end, whereas others, such as the connective
+tissues, display profound changes. This essay was the
+first attempt to form a picture of the details of senile
+degeneration, but it did not reach any simple, general conclusion.</p>
+
+<p class='c007'>Later on, I myself<a id='r296'></a><a href='#f296' class='c014'><sup>[296]</sup></a> tried to complete the work, and
+for the purpose made use of the published results of all the
+investigators who had studied senile degeneration. I gave
+a summary of my conclusions in the following words:
+“In senile atrophy the same condition is always present:
+<em>the atrophy of the higher and specific cells of a tissue and their
+replacement by hypertrophied connective tissue</em>.” In the
+brain, the nerve cells disappear; that is to say, the cells
+which subserve the higher functions such as intellectuality,
+sensation, control of movement, and these are replaced by
+elements of a lower kind, in especial by neuroglœa, a kind
+of connective tissue of the brain. In the liver, the hepatic
+cells, of great importance to the nutrition of the organism,
+yield to connective tissue. In the kidneys, that tissue
+<span class='pageno' id='Page_239'>239</span>invades and blocks the tubes by which the necessary process
+of eliminating soluble waste matter is accomplished. In the
+ovaries, the ova, the specific elements which serve to propagate
+the race, are similarly eliminated and replaced by
+granular cells, a variety of connective tissue. In other
+words, a conflict takes place in old age between the higher
+elements and the simpler or primitive elements of the
+organism, and the conflict ends in the victory of the latter.
+This victory is signalised by a weakening of the intellect,
+by digestive troubles, and by lack of sufficient oxygen
+in the blood. The word conflict is not used metaphorically
+in this case. It is a veritable battle that rages in the
+innermost recesses of our beings. Distributed throughout
+every part of our bodies are certain cells which fulfil special
+functions of their own. They are capable of independent
+movement, and also of devouring all sorts of solid matter,
+a capacity which has gained them their name of phagocytes
+or voracious cells. The function these phagocytes
+fulfil is a very important one, for it is they that congregate
+in vast numbers around microbes or other harmful intruders,
+in order to devour them. Effusions of blood and other
+elements, on penetrating to parts of the body where their
+presence is disadvantageous, are absorbed by these phagocytes.
+In cases of apoplexy, where blood is shed into a part
+of the brain, setting up paralysis, the phagocytes cluster
+round the clot and devour the blood corpuscles it has
+encased. This absorption is a lengthy process, but by degrees,
+as the pressure of the effusion of blood is removed from
+the brain, and paralysis disappears, the health of the
+organism may become completely restored, recovery in such
+a case being due to the work of the phagocytes. After
+childbirth, when the uterus presents the appearance of a
+great open wound clotted with blood, it is again the phagocytes
+<span class='pageno' id='Page_240'>240</span>that clean it and re-establish the normal condition. It
+is plain, therefore, that the part played by these cells is
+beneficent.</p>
+
+<p class='c007'>The phagocytes may be divided into small active phagocytes,
+generally known as the microphags, and larger
+phagocytes called macrophags, which are sometimes active
+and sometimes still. The former, which are produced in
+the marrow of the bones, circulate freely in the blood, and
+occur as some of the white blood corpuscles, or leucocytes.
+They are distinguishable by their oval shape which facilitates
+their easy passage through the smaller blood-vessels, and
+allows of their accumulating in great numbers in the exudations
+that form around microbes. These exudations may
+be formed extremely rapidly, and so may arrest infection
+in the case of many diseases.</p>
+
+<p class='c007'>The absorption of extravasations of blood and the healing
+of wounds are the work of the macrophags. In a
+general way, the microphags may be said to rid us of
+microbes, and the macrophags to heal mechanical injuries,
+such as hæmorrhages, wounds, and so forth. Macrophags
+possess a single unlobulated nucleus, and occur as white
+corpuscles in the blood, lymph, and exudations, or as the
+fixed cells in connective tissues, the spleen, and the lymphatic
+glands, &#38;c.</p>

+</div>
+
+<p class='c007'>The phagocytes are endowed with a sensitiveness of their
+own, and by means of a sense of smell or taste are able to
+recognise the nature of their surroundings. According to
+the impression made upon this sense, they approach the
+object which arouses it, exhibit indifference to it, or withdraw
+from its vicinity. When, however, an infectious
+microbe finds its way into the body, the microphags are
+attracted by its excretions and swarm into the exudations
+surrounding it. The macrophags play a very important
+part in bringing about senile decay. The atrophy of the
+kidneys in old persons is attributable to their agency (Fig. 14).
+They accumulate in large quantities in these organs, clustering
+round about the renal tubes which they ultimately
+cause to disappear. Having appropriated the place of the
+renal tubes, the macrophags proceed to form connective
+tissue, which thus takes the place of the normal renal
+tissue. A similar process occurs in the other organs that
+degenerate in old age. In the brains of old persons and
+animals, for instance, it is known that a number of nervous
+cells are surrounded and devoured by macrophags (Fig. 15).
+Judging from the investigations mentioned above, I think
+I am justified in asserting that senile decay is mainly due
+to the destruction of the higher elements of the organism
+by macrophags. This conclusion has been confirmed by
+means of direct observation, which was the more necessary
+as it is contrary to the opinions of some biologists. Marinesco,<a id='r297'></a><a href='#f297' class='c014'><sup>[297]</sup></a>
+an authority upon everything connected with the
+nervous system, has disputed my theory, asserting that
+<span class='pageno' id='Page_242'>242</span>the destruction of the specific elements in the nervous
+centres of old persons is not brought about through the
+agency of macrophags. In support of his theory, M. Marinesco
+was good enough to send me a series of preparations
+from the spinal marrow of persons of very advanced years
+from which evidence of destruction by means of phagocytes
+or phagocytosis, was completely absent. I freely admit the
+absence of phagocytosis in M. Marinesco’s preparations, but
+these were derived from the cells of spinal marrow, which
+is much less subject to the ravages of senile decay than is
+the brain. Even in the lower portions of the encephalon,
+senility and its parallel, phagocytosis, are uncommon,
+whereas in the brains of old persons, which are more generally
+affected by senile decay, the higher elements are clearly
+shown to undergo destruction by macrophags (Fig. 15).
+The same phenomenon may be observed in the case of
+parrots and dogs of advanced age, and in other animals.</p>
+
+<p class='c007'>So universal a symptom of old age is the invasion of the
+tissues by macrophags, that it must be regarded as of immense
+importance. In order, however, to determine more
+precisely the nature of the function fulfilled by these phagocytes,
+it was necessary to select a specially favourable subject
+of investigation. My choice fell upon an examination
+into the causes of the hair turning white,<a id='r298'></a><a href='#f298' class='c014'><sup>[298]</sup></a> that being as
+a rule the first visible sign of approaching old age.</p>
+
+<p class='c007'>Hair, before it has lost its colour, is full of pigment scattered
+throughout the two layers of which each hair is
+composed. At a given moment, the cells of the central
+cylinder of a hair become active, and proceed to devour
+all the pigment within their reach. Once they are filled
+with coloured particles, these cells, which are a variety
+of macrophag (generally called pigmentophags or more
+<span class='pageno' id='Page_243'>243</span>properly speaking chromophags), become migratory, and,
+quitting the hair, either find their way under the skin or
+leave the body (Fig. 16). The colouring-matter of the hair
+is removed in this way
+by chromophags, leaving
+the hair colourless.</p>
+
+<p class='c007'>The process by which
+hair becomes white is of
+importance, because it
+shows that the activity
+of macrophags is a dominant
+factor in bringing
+about senile decay. The
+brittleness of old people’s
+bones is probably due to
+a similar cause, <em>i.e.</em>, to
+the absorption and destruction
+of the framework
+brought about by
+macrophags invading the
+layers of bone. There is
+still much that remains
+unknown in this subject,
+which is well worthy of
+special research.</p>

+</div>
+</div>
+
+<p class='c007'>The activity acquired
+by macrophags during old age is closely connected with the
+phenomena that are characteristic of certain chronic complaints.
+Sclerosis in old persons belongs to the same category
+as organic sclerosis, which may be set up by various
+morbid influences. The analogy between senile decay of the
+kidneys and chronic nephritis, commonly called interstitial
+nephritis, is incontestable. The destruction of nervous cells
+<span class='pageno' id='Page_244'>244</span>through the agency of macrophags, which we have already
+mentioned as occurring in old age, is equally a symptom
+of several diseases of the nervous centres, such as general
+paralysis of the insane. Arterial sclerosis in old persons is
+actually an inflammatory disease, similar to the inflammation
+of the arteries set up by other maladies.</p>
+
+<p class='c007'>The similarity between senility and disease has long been
+recognised, and partly accounts for the repugnance we all
+experience at the approach of old age. In childhood and
+early youth people regard themselves as older than they
+really are, and long to be “grown-up,” but having once
+arrived at man’s estate, they do not wish to grow old. An
+instinctive feeling tells us that there is something abnormal
+in old age. It cannot be regarded as a part of healthy
+physiological function. No doubt, because old age is the
+inevitable lot of mankind, it may be termed normal, in the
+same fashion as we call the pains of childbirth normal,
+since few women escape them. In both cases, however,
+we have to deal with pathological rather than physiological
+conditions. Just as every effort is made to relieve the
+sufferings of a woman in labour, so it is natural to try to
+suppress the evils accompanying old age, but whereas in
+childbirth an anæsthetic affords relief, old age is a chronic
+malady, a remedy for which is much harder to find. We
+have seen that in old age a struggle takes place between the
+higher elements and the phagocytes, the end being usually
+a weakening in vitality of the former, while the activity of the
+latter is enormously increased. It would appear, arguing
+from this, that one means of fighting against old age, pathologically
+speaking, would be to strengthen the higher elements
+of the organism, and to weaken the aggressive
+capacities of the phagocytes. Let me at once warn the
+reader that this is not presented as a definite, but as a
+<span class='pageno' id='Page_245'>245</span>possible solution of the problem, and is offered for consideration
+like many other hypotheses on scientific questions.
+The properties of cellular elements are easily changed when
+subjected to various influences, and it is therefore not irrational
+to seek some means of strengthening the blood corpuscles,
+nerve cells, liver cells, muscular fibres of the heart,
+and so forth. The task has become easier since the discovery
+of serums that have specific actions on the tissues.</p>
+
+<p class='c007'>In the third chapter I stated that serums were known
+which give precipitates only with the blood of man and
+of his near relatives the anthropoid apes.  Serum of
+this kind has a definite specific action. Serums may be
+prepared that dissolve only the red corpuscles of particular
+species of animals, and that are without action on the other
+organic elements. It has been found possible, even, to
+prepare a serum that arrests instantaneously the movements
+of human spermatozoa, and that is neutral to the
+similar cells of other animals.</p>
+
+<p class='c007'>These serums are all prepared in the same way. The
+cellular elements in question, spermatozoa or red corpuscles,
+cells of the liver or of the kidney, taken from one animal,
+are injected into an animal of another species. After
+several injections have been made, the serum of the animal
+operated on becomes active with respect to the cells introduced
+into its body. These serums were discovered by
+J. Bordet of the Pasteur Institute, but the results have
+been confirmed by investigators in other countries. The
+serums are specifically <em>cytotoxic</em>, that is to say, they poison
+particular kinds of cells.</p>
+
+<p class='c007'>Now it has been shown that such serums, employed in
+small doses, do not kill or dissolve the specific tissue elements,
+but actually strengthen them.<a id='r299'></a><a href='#f299' class='c014'><sup>[299]</sup></a> Here the case is
+<span class='pageno' id='Page_246'>246</span>analogous with the action of poisons, such as digitalis, which
+kill in strong doses, but which in weak doses improve or
+strengthen the action of certain tissues. In accordance
+with this indication, experiment has shown that small doses
+of a serum which is capable of dissolving the red corpuscles
+of human blood, actually increase the number of those in
+the body of a patient treated by injections. In the same
+way, in the case of a serum large doses of which destroy
+the red corpuscles of a rabbit, small doses increase the
+number of these elements in the blood.</p>
+
+<p class='c007'>Here there seems to be a rational method by which we
+may strive to strengthen the higher elements of the human
+body, and so prevent them from growing old. The task,
+at first sight indeed, seems an easy one, only necessitating
+the injection of a horse (or other animal) with finely minced
+atoms of human organs, such as brain, heart, liver, kidney,
+&#38;c., when serums could be drawn off in the course of a
+few weeks, capable of acting upon those organs. In reality
+the process would be a very difficult one to carry out, as
+human organs are rarely obtainable in a condition suitable
+for injecting into animals. Post mortems can only be legally
+made twenty-four hours after death, and there are many
+other obstacles in the way of removing organs from dead
+bodies. Even if all these difficulties were overcome, another
+difficulty that would present itself would be the experimenting
+with various doses of cytotoxic serums of various
+strength. It is not therefore to be wondered at that the
+<span class='pageno' id='Page_247'>247</span>attempt to reinforce the higher elements of the human
+organism will require much time. If it be necessary to
+strengthen the higher elements (nervous, hepatic, renal, and
+cardiac cells), it is plain that they undergo a progressively
+weakening process. It would be of the highest importance
+to ascertain the cause of this, for the knowledge would be
+a guide to future action.</p>
+
+<p class='c007'>The similarity between senile decay and the diseases
+entailing atrophy in the more important human organs
+suggests a similitude in cause. Scleroses of the brain,
+kidneys, and liver frequently originate in intoxication by
+poisons such as alcohol, lead, mercury, and so forth, or the
+disease may be induced by some virus, the virus of syphilis
+being a common cause.</p>
+
+<p class='c007'>The immense importance of venereal disease as a malevolent
+factor in the phenomena of old age, is especially
+manifested in arterial sclerosis. According to the careful
+investigations of a Swedish doctor, Edgren,<a id='r300'></a><a href='#f300' class='c014'><sup>[300]</sup></a> published in
+his “Monograph on Arterial Sclerosis,” one case in every
+five of this disease is caused by syphilis, and he shows that
+chronic alcoholism is an even more frequent cause (25 per
+cent.). These two factors when united are responsible for
+nearly half (45 per cent.) the cases of arterial sclerosis
+that occur. Syphilitic virus and alcohol act as poisons
+which bring about first degeneration and brittleness of the
+arterial walls, and eventually a weakening of the higher
+elements of the organism. The phagocytes, being cells of
+an inferior order, are less sensitive to these poisons, which
+accounts for their victory over the poisoned elements.</p>
+
+<p class='c007'>Rheumatism, gout, and infectious diseases only play a
+secondary part in setting up arterial sclerosis. Edgren
+asserts, as the result of very careful calculation, that in
+<span class='pageno' id='Page_248'>248</span>nearly every fifth case he found it was impossible to account
+for the origin of arterial sclerosis. In the majority of cases
+the sufferers were elderly persons who, according to Edgren,
+“were afflicted with physiological sclerosis.”<a id='r301'></a><a href='#f301' class='c014'><sup>[301]</sup></a></p>
+
+<p class='c007'>I take it that this sclerosis of unknown origin was by
+no means physiological but was pathological like that
+set up by syphilis or alcoholism. The question then arises
+whence comes the poison in such cases? In syphilis there
+is a virus of a definite nature to deal with, which causes
+infection or poisoning, and brings about arterial sclerosis,
+general paralysis, and other serious ailments. Alcoholism
+is a poison arising from fermentation, excited by microscopical
+fungi related to true microbes. Instances of
+arterial sclerosis which are due neither to syphilis nor to
+alcohol poisoning nor to any other known cause, can only
+be accounted for as probably arising from poisoning set up
+by the mass of microbes congregated in the human intestines.
+Among these microbes there may be some that are
+harmless, and possibly even beneficial, but there are undoubtedly
+a great number the presence of which is extremely
+prejudicial to health and life. It is impossible to enter into
+the details of such an important question, and a brief
+mention must suffice.</p>
+
+<p class='c007'>The human intestine contains an enormous quantity of
+bacteria, which, according to the recent investigations of
+Strassburger,<a id='r302'></a><a href='#f302' class='c014'><sup>[302]</sup></a> increase at the rate of 128,000,000,000,000
+each day. These microbes, of which there are few in the
+digestive portion of the alimentary canal, are very numerous
+in the large intestines, <em>i.e.</em>, in the lower part containing
+the waste material. The remains of undigested foods and the
+mucous secretions form a medium very favourable to the
+<span class='pageno' id='Page_249'>249</span>growth of microbes. This bacterial flora constitutes a third
+part of the human excreta. It is very varied, and contains
+an immense number of different species, among which are
+bacilli, cocci, and many kinds of other bacteria, about which
+little is known. The distribution of this bacterial flora
+shows that it contributes nothing to the well-being of man,
+being scanty in the digestive portions of the body, and
+abundant in other parts of the gut. This fact alone suffices
+to refute the theory of those who attribute great functional
+importance to the intestinal flora. This theory originated
+principally from the fact that certain animals perish when
+brought up under special conditions protecting them from
+the presence of microbes. Schottelius<a id='r303'></a><a href='#f303' class='c014'><sup>[303]</sup></a> was the first to
+try the experiment of rearing chickens in a cage specially
+constructed for this purpose. The chickens hatched out,
+and lived for a few weeks: then, there being no microbes
+within them and only sterilised food being given, instead of
+increasing in weight, they became thin and showed signs
+of starvation. Schottelius supplied them with food from
+which bacteria were no longer excluded, upon which the
+chickens rallied, and soon became completely restored to
+health. Madame Metchnikoff<a id='r304'></a><a href='#f304' class='c014'><sup>[304]</sup></a> tried a similar experiment
+with tadpoles, which, when kept in vessels and fed upon
+bread containing the usual microbes, developed normally,
+but which, when reared under conditions entirely free from
+the presence of microbes, lived on for some months, but in
+a degenerate condition, their development being arrested.</p>
+
+<p class='c007'>On the other hand, Nuttall and Thierfelder<a id='r305'></a><a href='#f305' class='c014'><sup>[305]</sup></a> succeeded
+in keeping alive for several days new-born guinea-pigs, the
+<span class='pageno' id='Page_250'>250</span>alimentary canals of which were free from microbes, and
+which were fed only on absolutely sterilised milk and
+vegetable matter. Notwithstanding this complete absence
+of microbes the guinea-pigs developed well.</p>
+
+<p class='c007'>As the two sets of experiments were conducted under
+conditions arranged so carefully that the chance of error was
+excluded, it is important to try to reconcile the apparently
+contradictory results. There is one point common to these
+three experiments, <em>i.e.</em>, that they were all executed upon
+newly born creatures. Now it is well known that at birth
+the digestive juices are often very imperfectly secreted. In
+the case of the guinea-pigs, these juices sufficed in quantity
+for the digestion of the diet provided, whereas in the cases
+of the chickens and the tadpoles, the digestive juices were
+incapable of fulfilling their function satisfactorily, and the
+introduction of microbes endowed with considerable digestive
+capacity into the intestines compensated for the
+functional inefficiency of the gastric juices. In addition to
+the guinea-pigs experimented upon by Nuttall and Thierfelder,
+there may be mentioned a whole series of lower
+creatures such as the larvæ of mites and other insects
+which are able to digest such indigestible material as wax
+and wool in spite of the total absence of microbes within
+their intestinal tubes. These experiments are corroborated
+by the established physiological fact that the gastric and
+pancreatic juices of mammals easily digest the most varied
+kinds of foods, even if treated so antiseptically as to ensure
+the total exclusion of microbes from the intestines.</p>
+
+<p class='c007'>I need not go further into this subject as the facts which
+I have cited suffice for my present purpose. The complete
+atrophy of the large intestines in the case of the woman
+referred to in chap. iv. proves not only that this portion
+of the alimentary canal is not indispensable to healthy
+<span class='pageno' id='Page_251'>251</span>life, but that life may be maintained in the absence of the
+flora of the large intestines. And this really is the centre
+of the problem. The useless bacterial flora may give rise
+to serious or fatal maladies. Wounds of the abdomen are
+really serious only when they penetrate the large intestines
+and so allow the entrance of bacteria from that region to
+the peritoneal cavity. In such an event, the microbes
+rapidly multiply in the organism and produce a grave and
+frequently mortal illness. So long as the microbes remain
+within the intestines very few of them get into the circulation,
+and with these few the organism is able to cope.
+While most of the microbes are confined within the walls
+of the alimentary canal, the soluble excretions produced
+by them pass through into the lymph and blood. Quite
+a number of different facts establish this. Thus, for instance,
+it has been known for long that the urine of human beings
+and of animals contains a series of substances such as
+derivatives of phenol, indol, creosol, skatol, and so forth.
+In certain diseases the amount of these substances greatly
+increases. The stagnation of the contents of the intestines
+increases the amount of phenol and indol. Such facts and
+many others make it probable that these substances are
+the products of the bacterial flora of the intestines. They are
+absorbed by the intestinal wall, pass into the general circulation,
+and may give rise to various symptoms of a more
+or less serious nature.</p>
+
+<p class='c007'>Baumann, who has done much work on the subject, has
+brought together a series of arguments supporting the
+bacterial origin of the presence in the urine of the substances
+in question. Ewald, working from another point of view
+has obtained strong confirmation of Baumann’s suggestions.
+He had the opportunity of making observations on a female
+patient, in whom, on account of a strangulated hernia, an
+<span class='pageno' id='Page_252'>252</span>intestinal fistula was established. Throughout the time
+during which the large intestines were inactive, the urine
+contained neither phenol nor indol. But as soon as the
+fistula was closed and communication with the large intestine
+had been re-established, phenol and indol reappeared in the
+excreta. Ewald formed the opinion, therefore, that these
+substances were products of the large intestine.</p>
+
+<p class='c007'>I need not weary the reader with more of the facts serving
+to show that the bacterial flora of the large intestines is
+the source of many poisons harmful to the body. It is
+among such substances that we must look for the slow
+poisons which, in the absence of syphilis or alcoholism,
+produce the arterial sclerosis of old age.</p>
+
+<p class='c007'>In the fourth chapter I gave reasons to support my view
+that the large intestine in mammals had been developed
+because, by storing the products of digestion, it allowed
+them to run long distances without stopping, and so was
+an advantage in the struggle for existence. Moreover, the
+microbes which abound in the contents of the gut make
+it possible to use certain substances such as cellulose,
+that are difficult to digest. But these two advantages do
+not count in the case of the human race. Man does not
+secure his prey or escape from his enemies by the rapidity
+of his locomotion. The great development of his intellectual
+powers has given him advantages of another kind.
+Moreover, by the use of cooking and the cultivation of
+plants of high nutritive value, he is able to dispense with
+the digestion of cellulose.</p>
+
+<p class='c007'>There is another side to the picture. Ignorant of death
+and of old age, mammals have acquired the advantages of
+a large intestine at the expense of longevity. I have already
+stated that birds live longer than mammals. Birds are
+practically devoid of a large intestine, and maintain a
+<span class='pageno' id='Page_253'>253</span>bacterial flora very much poorer than that found in mammals.
+There is one exception to this rule, an exception of great
+importance. Ostriches and their allies, the largest known
+birds, are characterised by absence of the power of flight and
+by rapidity of terrestrial locomotion by which they escape
+their enemies. These are the only birds in which the large
+intestine is well-developed. The duration of life is much
+less in their case than in that of smaller birds, such as
+parrots, ravens, and swans. According to M. Rivière, who
+has been engaged in ostrich farming in Algeria, these large
+birds do not live more than thirty-five years. The mode
+of life, and the shorter duration of life, the huge development
+of the large intestines and the rich bacterial flora found
+therein make the ostriches much more like mammals
+than birds.</p>
+
+<p class='c007'>It is to be noticed that many birds in which the duration
+of life is long do not possess a cæcum, the portion of the
+alimentary canal that contains most bacteria. Examination
+of the intestinal contents of parrots shows that there
+exist in these birds very few microbes. A comparative
+study shows plainly that the existence of an abundant
+intestinal flora, useless for digestion, helps to shorten life
+by producing bacterial poisons which weaken the higher
+elements and strengthen the phagocytes.</p>
+
+<p class='c007'>The human race has inherited from its ancestors an enormous
+large intestine and conditions favourable to the life
+of bacteria. It has to endure the disadvantages of this
+heritage. On the other hand, the brain of man is very
+highly developed, and with the increase of intellectual
+power has come a consciousness of old age and death. Our
+strong will to live is opposed to the infirmities of age and
+the shortness of life. Here lies the greatest disharmony of
+the constitution of man.</p>
+
+<p class='c007'><span class='pageno' id='Page_254'>254</span>If we desired to make the phenomena of old age physiological
+rather than pathological, it would be necessary to
+reduce the evils arising from the presence of a large intestine.
+It is impossible, I may at once say, to wait for the operation
+of forces independent of the human will and that might lead
+to the suppression of an organ which has become useless.
+Man, guided by exact science, must strive to accelerate or
+anticipate such a result. In spite of the progress of surgery,
+I do not expect to find in our time that the large intestine
+will be removed by operation. Perhaps in the distant
+future such a proceeding will become normal. For the
+present it is more reasonable to attack the harmful microbes
+of the large intestine. In the varied flora of that region
+there exist microbes termed anærobic, because they are
+able to live in the absence of free oxygen, obtaining what
+they require by the decomposition of organic matter. Such
+decomposition is attended by fermentations and putrefactions,
+and the production of poisons, such as the alkaloids
+(ptomaines), fatty acids, and even true toxins.</p>
+
+<p class='c007'>In the human intestines under normal conditions, putrefaction
+occurs only very slightly, or does not occur at all.
+But in intestinal diseases of children and of adults, the
+microbes of putrefaction multiply abundantly and produce
+copious secretions which inflame the intestinal walls. To
+avoid these diseases of putrefaction in the case of infants,
+it has been suggested to use as food only sterilised milk or
+other foods quite free from microbes. This regimen has
+proved extremely successful.</p>
+
+<p class='c007'>In the investigation of the factors that hinder putrefaction,
+it has been noticed that milk putrefies with considerable
+difficulty, whereas meat, preserved under the same conditions,
+decomposes very readily. Investigators have attributed
+the stability of milk to the presence of casein or of
+<span class='pageno' id='Page_255'>255</span>milk-sugar. However, investigations recently made by
+Bienstock<a id='r306'></a><a href='#f306' class='c014'><sup>[306]</sup></a> and confirmed by Tissier and Martel<a id='r307'></a><a href='#f307' class='c014'><sup>[307]</sup></a> have
+proved the existence of certain microbes that hinder the
+putrefaction of milk. These are in particular the microbes
+that sour milk, <em>i.e.</em>, cause the formation of lactic acid, and
+which are antagonistic to the microbes of putrefaction. The
+latter multiply only in an alkaline medium. The lactic acid
+microbes produce large quantities of acid and so hinder the
+multiplication of the organisms of putrefaction. Putrefaction
+takes place rapidly, in spite of the presence of the lactic
+acid microbes, if there be added soda to macerations of
+meat or milk. Such facts explain how it is that lactic acid
+frequently stops some cases of diarrhœa, and why treatment
+with lactic acid is so useful in maladies associated with
+putrefaction of the intestinal contents. It makes intelligible,
+moreover, the medicinal value of fermented milk.</p>
+
+<p class='c007'>Rovighi,<a id='r308'></a><a href='#f308' class='c014'><sup>[308]</sup></a> an Italian physician, drank daily a litre and
+a half of kephir, a preparation made by subjecting milk to
+lactic acid and alcoholic fermentations. He found that in
+a few days the products of intestinal putrefaction in his
+urine either disappeared or were greatly reduced.</p>
+
+<p class='c007'>It is plain, then, that the slow intoxications that weaken
+the resistance of the higher elements of the body and that
+strengthen the phagocytes may be arrested by the use of
+kephir, or still better of soured milk. The latter differs
+from kephir in that it contains no alcohol, and alcohol in
+course of time diminishes the vitality of some important
+cells in the body. The presence of a number of the lactic
+acid bacteria is inimical to the growth of the bacteria of
+putrefaction, and so is of great service to the organism.</p>
+
+<p class='c007'><span class='pageno' id='Page_256'>256</span>But it is not enough merely to introduce useful microbes
+into the body. We must also prevent the entrance of
+“wild” microbes, many of which are harmful. Soil, especially
+when it has been manured, contains large numbers
+of microbes, some of which are harmful. Bienstock found
+that the soil of the strawberry-beds in his garden contained
+the bacilli of tetanus. For three weeks he swallowed some
+of this soil, but found that the bacteria were destroyed in
+his intestines, which he attributed to the action of the normal
+bacterial inhabitants of the alimentary canal. It is probable
+that if this arresting action were weakened the body
+would be infected by tetanus from spores of the tetanus
+microbe swallowed with earth or strawberries or green
+vegetables. Moreover, besides the organisms of tetanus,
+there are many other dangerous anærobic bacteria in
+manured garden soil.</p>
+
+<p class='c007'>Obviously we should eat no raw food, but confine our
+diet rigidly to food that has been thoroughly cooked or
+sterilised. The exclusion of “wild” microbes and the
+introduction of beneficial microbes, such as those of lactic
+acid fermentation, must be of great service to health. I
+know of individuals who have derived great benefit from
+such a regimen.</p>
+
+<p class='c007'>Science, even in its present imperfect condition, has many
+weapons by which to prevent or at least diminish the slow
+and chronic poisoning of the organism that leads eventually
+to the degeneration of the higher elements. When these
+elements are being destroyed by syphilis or alcoholism the
+struggle must be directed against these evils. It is long
+since we have known how to do this; that success has not
+been greater is due to the carelessness of the people who
+are concerned.</p>
+
+<p class='c007'>To strengthen the resistance of the higher elements and
+<span class='pageno' id='Page_257'>257</span>to transform the “wild” population of the intestine into
+a cultured population, these are the means by which the
+pathological symptoms may be removed from old age, and
+by which, in all probability, the duration of the life of man
+may be considerably increased.</p>
+
+<p class='c007'>If it be found impossible to eliminate all the harmful
+microbes from the flora of the intestines, those that are
+refractory may be rendered harmless by appropriate serums.
+We know already a serum that is specific against the microbe
+of botulism, an organism capable of exciting serious disturbance
+if it gain entrance to the alimentary canal.</p>
+
+<p class='c007'>Our inmost convictions assure us that life is too short,
+and since the remotest ages attempts have been made to
+prolong it. I need hardly mention the quest of the Middle
+Ages for an elixir of life, but many thoughtful men have
+occupied themselves with the problem.</p>
+
+<p class='c007'>Descartes, who was deeply interested in the subject,
+believed himself to have found a mode of lengthening
+human life. Bacon published a tract on life and death,
+and in it gave advice as to how old age might be reached;
+blood-letting and the use of saltpetre were parts of his
+specific.</p>
+
+<p class='c007'>One of the oldest methods in the world consisted in
+bringing old men in contact with the bodies of young girls.
+David, King of Israel, employed this method, which at a
+much later period came into fashion.</p>
+
+<p class='c007'>Eighteenth-century quacks proclaimed a number of
+specifics, among which was the “holy water” of Saint
+Germain, an infusion of senna, merely purgative in its
+effects. It is certain that some of the medicines used for
+the purpose, by emptying the large intestine, decreased the
+bacterial flora, and so checked the formation of the poisons
+that are harmful to the higher elements.</p>

+This treatise had a great vogue in its day, and contained
+many interesting and just observations. Besides advocating
+cleanliness and moderation, Hufeland advised that “we
+should use vegetable rather than animal food, as animal
+food was more liable to putrefaction, whilst vegetable substances
+contained an acid principle that retarded our mortal
+enemy, putrefaction.”<a id='r310'></a><a href='#f310' class='c014'><sup>[310]</sup></a> Here the physician of a day long
+past anticipated one of the discoveries of modern science.</p>
+
+<p class='c007'>In our time scientific men have not ceased to concern
+themselves with the prolongation of human life. Professor
+Pflüger, of Bonn, one of the most distinguished of living
+physiologists, has published an essay<a id='r311'></a><a href='#f311' class='c014'><sup>[311]</sup></a> in which he gave
+the results of his inquiries into this subject. He first stated
+that investigations into the habits of those who had attained
+a great age did not give information sufficiently exact.
+Pflüger laid stress on the means of avoiding infectious
+maladies, and summed up as follows: “Finally, I can do
+no better than to associate myself with the advice given
+in all the treatises on the prolonging of life: avoid the
+things that are harmful and be moderate in all things.”</p>
+
+<p class='c007'>A year later, a well-known German physician, Dr. Ebstein<a id='r312'></a><a href='#f312' class='c014'><sup>[312]</sup></a>
+published a very careful treatise on the same subject. He
+had been struck by the fact that among those who have
+reached a great age, there have been several who had led
+<span class='pageno' id='Page_259'>259</span>an exuberant life, full of excesses, notably in the consumption
+of alcohol. None the less, Ebstein advised either a
+complete avoidance of alcoholic liquor, or at the most an
+extreme temperance in the use of it. He prescribed in
+addition the simplification of the conduct of life and the
+avoiding of anything that is unwholesome.</p>
+
+<p class='c007'>Study of such works, which are written in a scientific
+spirit, convinces me that a science of the prolongation of
+life could be built up. An exact investigation of the phenomena
+of old age would contribute to this object. At any
+rate, we cannot set aside as chimerical plans to make old age
+a natural process, and one easy to bear. I believe, moreover,
+that attempts to prolong life deserve to be encouraged, the
+more so as instances of longevity are already numerous.</p>
+
+<p class='c007'>Quite a number of cases of centenarians who have preserved
+intellect and vigour until death have been recorded.
+It is unnecessary to relate the histories of these persons,
+of whom some attained such ages as 120, 140, and even
+185 years (Saint Mungo of Glasgow). My friend, Professor
+Ray Lankester,<a id='r313'></a><a href='#f313' class='c014'><sup>[313]</sup></a> thinks that such unusually old persons
+are monstrosities comparable with those who have attained
+a gigantic stature. But centenarians are more numerous
+than giants, and while the latter exhibit marked signs of
+pathological weakness the former surprise us by their health
+and vigour.</p>
+
+<p class='c007'>The longevity of the Israelites recorded in the Old Testament
+is well known. No doubt there is much exaggeration
+in these naïve records. Was it an error of exaggeration to
+impute an age of 969 years to Methusaleh, or of 595 to
+Noah, or were these ages reckoned on a different basis?
+Henseler<a id='r314'></a><a href='#f314' class='c014'><sup>[314]</sup></a> suggested that in these cases each season was
+<span class='pageno' id='Page_260'>260</span>counted as a year, so that the age of Methusaleh was really
+only 242 years, a length of life not so vastly greater than
+ages recorded in modern times.</p>
+
+<p class='c007'>There is evidence to show that in somewhat later Biblical
+times ages were reckoned in our years. Thus in the Book
+of Numbers (i. 3, 20, 22) reference is made to those “From
+twenty years old and upward, all that are able to go forth
+to war in Israel.” The limit of age given shows clearly
+that the years counted were our years. This interpretation
+is supported by many other passages in the Pentateuch,
+notably where annual harvest feasts are spoken of. We
+may therefore accept as probable the assignment of such
+ages as 100 or 120 years to several Biblical personages, such
+as Aaron, Moses, and Joshua. And the words put in the
+mouth of Jahveh may be accepted as important evidence:
+“And the Lord said, My spirit shall not always strive with
+man, for that he also is flesh: yet his days shall be an hundred
+and twenty years.”<a id='r315'></a><a href='#f315' class='c014'><sup>[315]</sup></a></p>
+
+<p class='c007'>The longevity of that remote period must have surpassed
+the age of the present time. From the circumstance that
+the greatest number of deaths occurs at the age of seventy
+years, Ebstein<a id='r316'></a><a href='#f316' class='c014'><sup>[316]</sup></a> has inferred that seventy years is the
+normal duration of life. Although there is no doubt but
+that the duration of human life has become longer in the
+nineteenth century, we must believe that it was still longer
+in Biblical times, a fact that is not particularly surprising.</p>
+
+<p class='c007'>I have called attention to the important influence of
+syphilis in inducing premature and pathological old age,
+as that disease is a chief cause of arterial sclerosis and
+degeneration of the higher elements of the body. Syphilis
+has an influence still more serious because its effects are
+inherited. Now although the Bible refers to diseases of
+<span class='pageno' id='Page_261'>261</span>the genital organs and lays stress on circumcision, there is
+no direct evidence in it as to the existence of syphilis.
+Ebstein, in a treatise on the medicine of the Bible,<a id='r317'></a><a href='#f317' class='c014'><sup>[317]</sup></a> is
+confident that there is no reference to syphilis in that Book.
+Moreover, in the ancient world generally, syphilis was either
+unknown or existed only in an attenuated form. Haeser,<a id='r318'></a><a href='#f318' class='c014'><sup>[318]</sup></a>
+the author of the best modern treatise on the history of
+medicine, thinks that if syphilis did exist in the ancient
+world, it occurred in a localised form and did not become
+a general disease of the system as is the case among the
+moderns.</p>
+
+<p class='c007'>Humanity would make a great stride towards longevity
+could it put an end to syphilis, which is the cause of one fifth
+of the cases of arterial sclerosis. The suppression of
+alcoholism, the second great factor in the production of
+senile degeneration of the arteries, will produce a still more
+marked extension of the term of life. Scientific study of
+old age and of the means of modifying its pathological
+character will make life longer and happier. Although
+modern knowledge is still imperfect, there is no reason to
+be pessimistic on the subject of old age.</p>

+
+<p class='c006'>From what I have said in the last chapter, it is plain that,
+perhaps before very long, it will be possible to modify old
+age. Instead of retaining its existing melancholy and
+repulsive character, it may become a healthy and endurable
+process; it may also be that the duration of life will be
+prolonged. However, it may be asked, what shall we
+gain by attaining the age of 100 or 120 years instead of
+70 or 80, if there still remain for us the appalling fate of
+the inevitable annihilation of death. Marcus Aurelius said
+that he who makes a long journey and he who makes
+it short, alike meet death at the end; and that once
+they are over, three years or a century are much alike.
+Such assertions, however, do not take into account the
+difference in the values we set on a thing at different ages.
+A man of the age of twenty-five years and one fifty years old
+reason differently, and are affected differently by the same
+surroundings. The outlook on life changes in the same
+<span class='pageno' id='Page_263'>263</span>individual as he gets on in years. Young people judge of
+their impressions by comparison with their ideals, and as
+the latter are very high, they are dissatisfied with things
+as they really are. They are exacting, and discontented
+with what they can get out of the real world; grown up
+people and those of advanced years are more easily satisfied
+because they have a clearer knowledge of the true value
+of things. As I have already had occasion to point out
+in a previous chapter, the young are more inclined to
+pessimism than the old. We see, then, that appreciation
+of life changes with age. It is the same with regard to
+death. It has often been said that life is only a preparation
+for death. Cicero said, “From our youth upwards
+we must accustom ourselves to face our last moments
+without fear. If not, there is an end to peace, since it is
+quite certain that we must die.” Philosophy has been
+called the art of preparing for death.</p>
+
+<p class='c007'>Before considering in what direction science may direct
+our steps towards solving the problem of death, which in
+the words of St. Paul is the “last enemy to be destroyed,”
+let us see how much is known about it.</p>
+
+<p class='c007'>We are so accustomed to look upon death as something
+natural and inevitable, that it has long since come to
+be regarded as inherent in organisms. However, when
+biologists investigated the matter more carefully, they
+failed to discover any proof of the accepted doctrine.
+Observation of members of the lowest grade of animal life,
+such as infusorians and other protozoa, has shown that
+these reproduce by simple division, and in a very short
+time multiply to an astonishing extent. Generation
+succeeds generation, with the utmost rapidity and without
+the intervention of death; no single corpse appears in
+the swarming masses of animalculæ. From such facts,
+<span class='pageno' id='Page_264'>264</span>which are extremely easy to confirm, several biologists,
+and in specially Bütschli and Weismann,<a id='r319'></a><a href='#f319' class='c014'><sup>[319]</sup></a> have deduced
+an immortality of the unicellular organisms. When an
+infusorian has divided, each daughter organism rapidly
+completes itself and sets about again dividing in the
+fashion of its parent. The process may be more complicated,
+as in the cases where a single organism breaks up
+into several portions each of which contains an essential
+part of the parent organism. Many unicellular organisms
+reproduce in such a fashion, and as each animal divides
+simultaneously into a number of individuals of the new
+generation, the individuality is destroyed. It is possible
+to admit with Götte<a id='r320'></a><a href='#f320' class='c014'><sup>[320]</sup></a> that such a process is natural death,
+although there is no actual destruction and no corpse.</p>
+
+<p class='c007'>In any event it cannot be disputed that lower organisms
+are not subject to the natural death that comes inevitably
+to man and the higher animals. It has been suggested
+that the debility of infusorians after a rapid series of
+divisions, and before conjugation, is to be interpreted as
+natural death. But the rejuvenescence that follows conjugation
+is incompatible with such an interpretation.
+Moreover, when conjugation does not occur, and the debility
+leads to death, the deaths must be regarded as accidental.</p>
+
+<p class='c007'>The theory of the immortality of unicellular organisms
+is now generally accepted. However, there are animals,
+higher in the scale of life, to which natural death does not
+come. Among these occur certain forms of considerable
+complexity, composed of many organs and very many
+cells, such as many polyps, and some worms, especially
+annelid worms. Some annelids (Fig. 17) reproduce by
+<span class='pageno' id='Page_265'>265</span>transverse divisions very actively. “Throughout the
+summer,” said E. Perrier,<a id='r321'></a><a href='#f321' class='c014'><sup>[321]</sup></a> “the Naïdimorpha are devoid
+of genital organs, and apparently
+(according to unpublished
+observations of Maupas), they
+may be kept alive for several
+years, and perhaps indefinitely,
+in this sexless condition.” This
+certainly may be regarded as a
+case of immortality due to the
+indefinite power of regeneration
+possessed by a complex animal.</p>
+
+<p class='c007'>The facts that I have cited
+show that death is not necessarily
+inherent in living organisms.
+Naegeli,<a id='r322'></a><a href='#f322' class='c014'><sup>[322]</sup></a> a well-known German
+botanist, has asserted even that
+natural death does not exist in
+nature. He points out that trees,
+more than a thousand years old,
+perish not by natural death, that
+is to say, by the gradual decay
+of their vitality, but by some
+catastrophe.</p>

+<p class='c007'>The age of the famous dragontree

+<span class='pageno' id='Page_266'>266</span>It was only by a catastrophe that the long-lived giant
+perished. The Baobab is reputed to live for five or six
+thousand years.</p>
+
+<p class='c007'>In a recently published essay, Jacques Loeb,<a id='r323'></a><a href='#f323' class='c014'><sup>[323]</sup></a> a distinguished
+biologist in Chicago, has made a study of
+natural death, and has come to the conclusion that there
+is no good evidence for its existence. He has observed
+that ripe, but unfertilised eggs of sea hedgehogs (Echini)
+die a few hours after they have been discharged. Loeb
+thinks that this may be a case of natural death, but I
+cannot agree with this opinion, as an egg that has not
+been fertilised by a spermatozoon may be compared with
+an organism deprived of its nutrition and so dying of
+starvation. In both cases death is purely accidental and
+could have been avoided.</p>
+
+<p class='c007'>If natural death does exist, it must have appeared on
+the face of the earth long after the appearance of life.
+Weismann has suggested that death arose as an adaptation
+for the advantage of the species, that is to say, in relation
+to the surrounding conditions of existence, and not as an
+absolute necessity inherent in the nature of the living
+substance. He thought that as worn organisms are no
+longer suited for reproduction or for the struggle for life,
+natural death was due to natural selection, it being necessary
+to maintain the species in a vigorous state by weeding out
+the debased individuals. But the introduction of death
+for that purpose was superfluous, since the debility caused
+by old age in itself would eliminate the aged in the course
+of the struggle for existence. Violent death must have
+appeared almost as soon as living things came into being.
+The infusorians and other low organisms, despite their
+<span class='pageno' id='Page_267'>267</span>potential immortality, must have been subjected perpetually
+to violent death, falling victims to larger and stronger
+organisms. It is impossible to regard natural death, if
+indeed it actually exists, as the product of natural selection
+for the benefit of the species. In the press of the world
+natural death rarely could come into operation, because
+maladies or the voracity of enemies so frequently cause
+violent death.</p>
+
+<p class='c007'>No doubt a certain number of deaths are recorded in
+statistics as being due to old age, without visible malady.
+Sometimes decrepit old men feel no pain and seem to fall
+quietly into their eternal sleep; but autopsy reveals serious
+lesions of the internal organs. There is reason to believe
+that even such deaths are in reality violent and are usually
+caused by infectious microbes. The general effect on the
+mind produced by examination of the collected facts is
+not an acceptance of the view that natural death is
+essentially inherent in living organisms, but the production
+of a wish to discover if there be any real proof of its
+existence.</p>
+
+<p class='c007'>For some time natural death has been ascribed only to
+the parts of the body that are of use in the individual life.
+Those cells, the function of which is to secure reproduction
+of the species, are, like unicellular organisms, potentially
+immortal. The egg-cell of the female is transformed into
+a fœtus, and so is the starting-point of the new generation,
+while the sexual cells of the new generation give rise to the
+third generation, and so on, in an endless chain of life. The
+greater number, by far, of the eggs and spermatozoa perish;
+but their death is not natural but violent, being due to
+harmful external agencies. An infinitesimal minority of the
+sexual cells survive indefinitely in the successions of generations.</p>
+
+<p class='c007'><span class='pageno' id='Page_268'>268</span>Scientific proof exists, therefore, that our bodies contain
+immortal elements, eggs or spermatozoa. As these
+cells not only are truly alive but exhibit properties that
+are within the category of psychical phenomena, it would
+be possible to build up a serious thesis on the immortality
+of the soul.</p>
+
+<p class='c007'>Observations on protozoa, and especially on the infusorian
+group of protozoa, show that these simple beings,
+each of which is composed of no more than a single cell, possess
+a high degree of sensibility. They select their food,
+distinguish living from dead animalculæ,<a id='r324'></a><a href='#f324' class='c014'><sup>[324]</sup></a> seek out their
+mates for conjugation, avoid danger, and hunt their prey;
+in fact, they are in possession of a set of qualities that must
+be included in psychical phenomena. Although such
+phenomena are very much lower in the case of the infusorians
+than in the case of higher animals, it is possible
+to speak of the soul of protozoa. Moreover, as the body
+is immortal by reason of its indefinite power of reproduction
+by division, the soul also of these creatures is immortal.
+However, the soul is so primitive that it is impossible to
+speak in definite terms about it.</p>
+
+<p class='c007'>As the sexual cells of the human body are immortal,
+like the protozoa, the problem arises if these too be
+endowed with an immortal soul. Our existing knowledge
+makes it impossible to doubt that ova and spermatozoa
+have sensibility in a degree as high as that of the protozoa.
+The ova shed secretions that arouse the sensibility of the
+spermatozoa, and the latter, directed by this specific
+“odour” (the occurrence being known technically as
+chemotaxis), make their way to the ovum and penetrate it.
+Some substances, arousing the spermatozoa into activity
+<span class='pageno' id='Page_269'>269</span>and movement, attract them, others repel them. The
+phenomena of chemotaxis were shown for the first time
+in the case of cryptogams by Pfeffer, the distinguished
+botanist, and since then the male cells of many plants and
+different kinds of animals have been proved to possess
+sensibility.</p>
+
+<p class='c007'>When ova and spermatozoa succeed in conjugating, they
+produce an individual of the next generation, to which
+they transmit what Haeckel has called the “cellular soul.”<a id='r325'></a><a href='#f325' class='c014'><sup>[325]</sup></a>
+This soul, then, is really immortal, inasmuch as the bodies
+of the reproductive cells are immortal.</p>
+
+<p class='c007'>Although it is true that our bodies contain elements
+endowed with immortal souls, it by no means follows
+that our conscious souls are immortal. In an earlier
+chapter, I have already pointed out that the psychical
+phenomena of many of the cells of our body and the cellular
+souls of these are outside our consciousness. We have no
+consciousness of the perpetual battle waged by the phagocytes
+against the microbes that endeavour to obtain a
+foothold in our tissues. None the less the phagocytes are
+elements endowed with mobility and sensibility and possessing
+a cellular soul like that of the protozoa.</p>
+
+<p class='c007'>A woman has no consciousness of the numerous spermatozoa,
+with their cellular souls, that enter her body, nor
+of those that fertilise her egg-cells; she is even without
+consciousness of the much more highly developed soul of
+the fœtus. A child before birth possesses psychical qualities
+much more numerous and more perfect than those of the
+reproductive cells. It is capable of responding to certain
+sensations and of performing movements. A child, in the
+later months of its prenatal existence, possesses the senses
+of touch and taste and, within limits, the sense of
+<span class='pageno' id='Page_270'>270</span>sight.<a id='r326'></a><a href='#f326' class='c014'><sup>[326]</sup></a> This soul is outside the consciousness of the mother.
+The mother cannot even tell by her consciousness if she bears
+under her girdle one or two embryonic souls. And so
+the immortality of the cellular soul has no relation to the
+problem of death.</p>
+
+<p class='c007'>It is a common opinion that only the reproductive cells
+of man and animals are immortal, and that the other
+elements of the body are mortal, the latter, if they escape
+violence, dying a natural death. A contrast has been
+drawn between the mortal cells in which is resident the
+life of the body and the immortal cells on which the species
+depends. However, when non-reproductive cells possess
+the power of regeneration, it is impossible to deny their
+immortality. When a polyp or a worm reproduces by
+division, a large number of cells go to form the new individual,
+and these cells are immortal in the fashion of the infusoria.</p>
+
+<p class='c007'>Immortal animals occur only among the lower invertebrates.
+The power of regeneration fades away in the higher
+ranks of the scale of life. Whilst worms may be divided
+in several pieces, each piece being capable of regeneration
+so as to form a new worm, when molluscs are cut they
+display only a limited capacity for regeneration. If the
+antennæ of a snail be amputated they will be renewed,
+but if the whole creature be cut in pieces death follows.
+Some of the lower vertebrates, such as newts and salamanders,
+can renew the tail and the limbs, but they cannot
+reproduce by division. Birds and mammals, the higher
+vertebrates, have very little power of regeneration, and
+tail and limbs are never reformed in their cases.</p>
+
+<p class='c007'>It seems to be the case that the advance in the general
+organisation of animals has involved a loss in the reproductive
+<span class='pageno' id='Page_271'>271</span>capacity of the cells and tissues. Even in the
+highest animals, some organs, such as the liver, still
+possess regenerative capacity; but, on the other hand,
+many cells have lost the power of regeneration completely.
+The nervous cells, in particular, which are the highest and
+most perfectly organised elements of the body, cannot
+reproduce themselves.
+After their
+initial appearance
+in the course of
+embryonic development,
+they pass their
+lives without regenerating
+or reproducing.
+In acquiring
+the highest qualities,
+that is to say,
+their psychical activity,
+they have lost
+completely the
+power of reproduction,
+the distinctive
+feature of immortal cells. If cells doomed to natural
+death really exist, it is in the nervous tissues that we must
+look for them.</p>

+</div>
+</div>
+
+<p class='c007'>The existence of natural death in the animal world
+cannot be denied, but it is very rare. The best example
+is that of the curious insects known universally as
+ephemerids (Fig. 18). Swarms of these delicate and
+graceful insects are to be seen in the summer months round
+lights. The perfect insects emerge from water, in which
+the six-legged larvæ feed on the organic débris contained
+in fresh water. The larvæ are not predaceous, and escape
+<span class='pageno' id='Page_272'>272</span>from their numerous and hungry foes by agility. They
+are long-lived, some of them passing two or three years in
+the mud of streams, and in the end become winged insects
+after a rapid metamorphosis. Near Paris, anglers have
+a popular name (<em>manne</em>, manna) for one species (<em>Palingenia
+virgo</em>) which emerges in swarms after sundown from the
+waters of the Seine and Marne. The swarms fly in huge
+numbers, like heavy snow-flakes, for a very short time,
+and then fall into the water (Fig. 19). The flight of
+these insects lasts only an hour or two, and then, in an
+enfeebled condition, they fall down in vast numbers. They
+are attracted by the lanterns lighted by fishermen, and
+are collected to be used as bait. The life in the winged
+condition is truly ephemeral and lasts no more than a
+few hours. The structure of the insect is adapted to this
+short life. The larvæ have powerful jaws, used in the
+mastication of food; the winged insects possess only
+vestiges of jaws. They are unable to feed, and so are
+adapted only for the briefest existence. Their hour of
+aerial life is devoted to love. As soon as they emerge
+the males and females unite, and the packets of eggs, which
+are deposited at once, fall into the water, and in a few
+weeks the young larvæ hatch out.</p>
+
+<p class='c007'>The mode of life and the organisation of the adult
+ephemerids show plainly that they are adapted to natural
+death. Death comes to them not because they are without
+food, or because the environment fails to provide something
+necessary to life, but merely because they emerge from
+the larval state in a non-viable condition, without the
+organs necessary to the maintenance of life.</p>

+possibility of the death having to be interpreted as violent,

+infectious disease does not attack these insects as soon as

+remote, must be examined. Instances are known of large

+by a species of mould which causes an epidemic. Every one
+has seen, especially in autumn, dead flies anchored to the
+window pane by a little tuft of white fluff. As so many
+individuals die about the same time, we might be disposed

+mould.</p>
+
+<p class='c007'>The occurrence of some terrible epidemic may be

+epidemic does not occur. The bodies of the dying ephemerids
+contain no microbe which could be the cause of
+death. Their death must be regarded as natural, as the
+result of their organisation, as essentially a part of the
+nature of the insects. Among the cells of their body there
+are many active phagocytes. Is it possible to attribute
+death to ravages that these cells may cause among the
+higher cells and tissues? Microscopic examination, so
+far from supporting such a possibility, shows that the
+organs are quite normal in their intimate structure. The
+brain and central nervous system, the muscles and other
+organs, show no signs of that invasion by phagocytes found
+in cases of senile degeneration. In this example of natural
+death there is certainly no possibility of phagocytic intervention.</p>
+
+<p class='c007'>Some biologists have suggested that the rapid death
+of ephemerids and of some other insects is due to debility
+<span class='pageno' id='Page_275'>275</span>caused by the great effort of depositing the male and female
+sexual cells. On this supposition, the case would be
+analogous to the shock which is sometimes the consequence
+of a surgical operation. This hypothesis, however, may
+be excluded, for among the dead ephemerids there are
+many males that have not united with females. Among
+ephemerids males are much more numerous than females;
+many males have no opportunity of undergoing the sexual
+shock and of emptying the reproductive organs, and these,
+none the less, die as rapidly as the others.</p>
+
+<p class='c007'>As yet we do not know if all the tissues of the ephemerids
+die simultaneously in natural death. Most probably the
+cells of the nervous centres perish first, and so bring death
+on the others. The investigation ought to be made.</p>
+
+<p class='c007'>Death comes to the ephemerids in the midst of love, at
+the moment when their sexual instincts are satisfied. It
+would be very interesting to know the sensations of these
+creatures as they feel death come on them in the act of
+reproduction. Naturally it would be impossible to obtain
+a full answer to the question, but many interesting facts
+regarding it may be ascertained. All the ephemerids, not
+only those the life of which is so brief, but those that live for
+several days (<em>Chloë</em>, for instance), are extremely easy to capture.
+It is unnecessary to take them unawares or to use a
+net as in the case of flies, wasps, and many other insects.
+Ephemerids may be taken with the fingers in the simplest
+way, because they offer no resistance and show no desire
+to escape, although they have six legs and two or four wings.
+This is not an isolated case, for some other insects (as, for
+example, winged ants and aphides) allow themselves to be
+captured with the same carelessness.</p>
+
+<p class='c007'>Although the adult ephemerids are careless, the wingless
+larvæ are timid. When a tube is brought near them, among
+<span class='pageno' id='Page_276'>276</span>the water plants, with the object of capturing them, they
+rapidly move off. It often requires much patience and
+quickness to capture these larvæ (Fig. 20). The instinct of
+preservation of life displays itself by rapid flight.</p>
+
+<div  class='figleft id003'>
+<img src='images/fig_20.jpg' alt='' class='ig001'>
+<div class='ic001'>
+<p><span class='sc'>Fig. 20.</span>—Larva of an ephemerid (<em>Chloërufulum</em>).</p>
+</div>
+</div>
+
+<p class='c007'>It is remarkable that the adult insect has lost the instinct
+of self-preservation. If it be touched it may move a short
+distance off, but it does not take to flight
+although its wings are very large, and its body,
+which of itself weighs little, is still lighter
+because the digestive tube is filled with air and
+not with food. As a rule, an ephemerid that
+has been touched does not even move off, but
+allows itself to be captured without any resistance.
+It would not be accurate to say that
+the larva’s instinct of self-preservation has been replaced
+in the adult by an instinct for death; but it must be
+admitted that the instinct of preservation has been totally
+lost. The lack of resistance cannot be explained by any
+defect in the organs of sense. Not only are the eyes of the
+larval stage fully preserved in the adult, but the adult males
+have enormous eyes to enable them to recognise the female
+in the turbulent flight which takes place at the close of the
+day. Ephemerids of all ages possess well developed tactile
+organs, and it is thus in spite of a highly organised sensory
+system that the adults offer no resistance to enemies.</p>
+
+<p class='c007'>It is no mere accident that the most striking examples
+of natural death occur among insects, for these creatures
+display an unusual stability in their cellular structure with a
+corresponding lack of the power of regeneration, in these
+particulars resembling man and the higher animals. The
+cells of the nervous system are very complex, and are well
+adapted for the highest function, that is to say, the psychical
+function. These highly endowed cells, however, are devoid
+<span class='pageno' id='Page_277'>277</span>of the power of reproduction. Many experiments have been
+made in relation to this, and it has been proved clearly that in
+cold-blooded vertebrates the brain and spinal cord with the
+nerve cells contained in them are capable of regeneration,
+whilst among mammals only extremely rare cases are known
+in which there has been any regeneration of the nervous
+elements. It is to be expected, then, that cases of natural
+death occur in the higher animals and especially in man.
+However, no case is known so plain as that presented by
+the ephemerids. I have already stated that of deaths
+apparently due to senile debility in man, a large proportion
+are certainly due to various infectious diseases that affect
+the old, such as pneumonia and nephritis. Close examination
+of the tissues confirms this conclusion, for the destruction
+of the higher elements by phagocytes produces what is really
+violent death and not a natural death like that of the
+ephemerids.</p>
+
+<p class='c007'>Natural death in man is probably a possibility rather than
+an actual occurrence. Old age is not a true physiological
+process but exhibits many morbid characters. That being
+the case, it is not surprising that it seldom ends in natural
+death. It is probable, however, that natural death occasionally
+occurs in very old men.</p>
+
+<p class='c007'>Attempts have been made to estimate the natural limits
+of human life. Flourens<a id='r327'></a><a href='#f327' class='c014'><sup>[327]</sup></a> based a calculation on the
+duration of the period of growth. If the latter be taken
+as one fifth the natural life, then human life ought to last a
+century. As centenarians are rare, the vast majority of
+deaths, which happen before that age has been reached,
+must be regarded as violent or accidental. The rule of
+Flourens, however, is arbitrary, and there is no evidence
+to show that it is exact. Probably in the human race, as
+<span class='pageno' id='Page_278'>278</span>in the case of ephemerids, the natural duration of life varies
+and cannot be expressed by a definite figure. In most cases
+it ought to be more than a hundred years, and only in rare
+cases ought it to be much less than that term. Probably
+there is a variation in the duration of life just as there is a
+variation of the date of sexual maturity for which rules
+may be laid down but not without anticipating numerous
+exceptions.</p>
+
+<p class='c007'>The existing pathological character of old age vitiates all
+conclusions as to natural death, and it is still impossible to
+be exact in speaking of that subject. It is known that
+certain organs and tissues remain alive for some time after
+death. In the case of certain infectious diseases, the heart
+may be removed from a human body more than thirty hours
+after death, and if placed under proper conditions will
+renew its life, and beat for several hours. The white corpuscles,
+the spermatozoa and the cilia of a corpse, may retain
+their power of movement. Does this also happen in the rare
+cases of natural death? That question must be answered
+in the future. The most important question relating to
+natural death is the following: Is the appearance of natural
+death in man accompanied by the disappearance of one
+instinct, the instinct of self preservation, and by the appearance
+of another instinct, the instinct of death? Do the
+phenomena of the ephemerids give us any indication as to
+this? An exact answer is not to be expected. As old age
+is generally what may be called an unnatural phenomenon,
+it is extremely rare for persons to approach the age of
+natural death with their faculties unclouded. I have had
+under observation a centenarian old woman, who still remembered
+some incidents of her youth; in her the desire
+to live was still strong, but her intellectual faculties were
+partially dim. Moreover, her brain, of which I have already
+<span class='pageno' id='Page_279'>279</span>spoken (p. <a href='#Page_241'>241</a>), showed a marked degeneration of the nerve
+cells due to the activity of macrophages.</p>
+
+<p class='c007'>I have obtained much information about a centenarian
+who was alive in Rouen in 1900, but a single glance at her
+photograph was enough to show that she no longer was in full
+possession of intelligence.<a id='r328'></a><a href='#f328' class='c014'><sup>[328]</sup></a> She was infirm in many ways.
+So also, Chevreul, the celebrated chemist, who died at the
+age of one hundred and three years, showed not the faintest
+wish for death; he clung to life, but his mental powers had
+grown weak.</p>
+
+<p class='c007'>The cases to which I have referred are typical, but there
+are exceptions worthy of close attention. Tokarski, in the
+essay on the fear of death, to which I referred in the sixth
+chapter, quoted the case of a female centenarian who stated
+as follows: “If you come to live as long as I have lived,
+you will understand not only that it is possible not to fear
+death, but to feel the same need for death as for sleep.” A
+new feeling had come into existence in the very old person,
+a feeling incomprehensible to those less old. Apparently
+this was a case in which the instinct of natural death had
+appeared in a centenarian whose mental faculties had been
+retained in a sufficiently perfect state.</p>
+
+<p class='c007'>I wish very much that I had myself been a witness of this
+old woman’s remarkable instinct in even one case of the
+many that I have observed. But all that have been pointed
+out to me as subject to this new desire have turned out to
+have been possessed of very different ideas. Some were old
+invalids, weary of pain and ready to exchange the sorrows
+of life for death, but who would have preferred to be healed
+and to live on in comfort. When the possibility of recovering
+health was suggested to them, they showed signs of
+pleasure and of the renewal of hope.</p>
+
+<p class='c007'><span class='pageno' id='Page_280'>280</span>Investigations that I have made in homes for the aged
+have led to negative results on this subject. No case
+showed the slightest sign of the approach of the instinct of
+death. However, I have learned from Dr. Fauvel of one
+case to add to the instance noticed by Tokarski. It was the
+case of an old lady whose health and circumstances were
+comfortable and who before her death showed a real desire
+for it and stated it in much the same language as that quoted
+by Tokarski. In Fauvel’s case, however, the old lady had
+reached the age of only eighty-five years. It seems probable
+that this was a second genuine case of the appearance of
+the instinct of death, and it is therefore interesting to notice
+that that instinct, like the sexual instinct, is subject to
+variation in the date of its appearance.</p>
+
+<p class='c007'>In my search for instances of the instinct of death, I made
+use of the large collection made by Lejoncourt,<a id='r329'></a><a href='#f329' class='c014'><sup>[329]</sup></a> but found
+that the information given by this author was very incomplete
+as to the mode of life and the last moments of his cases.</p>
+
+<p class='c007'>The Bible testifies to the frequency of old age in ancient
+times and to the complete preservation of the faculties in
+the aged. It also contains some references that may be
+interpreted as instances of the instinct of death. I may take
+its account of the death of some of the patriarchs. “And
+these are the days of the years of Abraham’s life which he
+lived, an hundred threescore and fifteen years. Then
+Abraham gave up the ghost, and died in a good old age,
+an old man, and <em>full of years</em>.”<a id='r330'></a><a href='#f330' class='c014'><sup>[330]</sup></a> “And the days of Isaac
+were an hundred and fourscore years. And Isaac gave
+up the ghost, and died, and was gathered unto his people,
+being old and <em>full of days</em>: and his sons Esau and Jacob
+buried him.”<a id='r331'></a><a href='#f331' class='c014'><sup>[331]</sup></a> “After this lived Job an hundred and forty
+<span class='pageno' id='Page_281'>281</span>years, and saw his sons, and his sons’ sons, even four
+generations. So Job died, being old and <em>full of days</em>.”<a id='r332'></a><a href='#f332' class='c014'><sup>[332]</sup></a>
+It is probable that the phrase “old and full of days,” which
+sounds strange in our ears, simply refers to the instinct of
+death, developed in well preserved old men who had attained
+ages of from 140 to 180 years.<a id='r333'></a><a href='#f333' class='c014'><sup>[333]</sup></a> The Biblical phrase is not
+merely a commonplace phrase applied to the death of celebrities
+for the references to deaths of other persons were put
+in different language. “And these are the years of the life
+of Ishmael, an hundred and thirty and seven years: and he
+gave up the ghost and died; and was gathered unto his
+people.”<a id='r334'></a><a href='#f334' class='c014'><sup>[334]</sup></a> “And Jacob lived in the land of Egypt
+seventeen years: so the whole age of Jacob was an hundred
+forty and seven years.”<a id='r335'></a><a href='#f335' class='c014'><sup>[335]</sup></a> “And Aaron was an hundred
+and twenty and three years old when he died in Mount
+Hor.”<a id='r336'></a><a href='#f336' class='c014'><sup>[336]</sup></a> “And Moses was an hundred and twenty years
+old when he died; his eye was not dim, nor his natural
+force abated.”<a id='r337'></a><a href='#f337' class='c014'><sup>[337]</sup></a> In only one of these later cases had the
+individual reached the age of one hundred and forty
+years, at which age, apparently, the instinct of natural
+death appeared.</p>
+
+<p class='c007'>It may seem altogether surprising and improbable to us
+that an instinct for death should arise in man, since we are
+imbued with an instinct of an opposite nature. From the
+facts that I collected in my sixth chapter, it was to be
+inferred plainly that the desire of life and the fear of death
+are manifestations of an instinct deep-rooted in the constitution
+<span class='pageno' id='Page_282'>282</span>of man. That instinct is of the same order as the
+instincts of hunger and thirst, of the need of sleep, of movement
+and of sexual and maternal love. The devotion and
+care bestowed on their young by female birds and mammals
+are known universally. And yet these instincts can be
+reversed. There is no sacrifice of which the mothers are
+not capable if it serve to save the life or promote the well-being
+of their offspring. Such devotion is a manifestation
+of the maternal instinct, which is one of the strongest
+instincts known to us. And yet that love, so tender and so
+absolute, lasts only for the time during which the wants
+of the young need to be satisfied. As soon as the young
+begin to be independent, the maternal love changes to
+indifference or to dislike. At the next breeding-period,
+maternal love reappears again, so that there is a periodic
+ebb and flow of the instinct.</p>
+
+<p class='c007'>The new-born babe takes an instinctive delight in the
+milk of his mother, which seems to him the only good food
+in the world. As soon as he can show his feelings, his
+intense satisfaction as he is suckled is plain. But this
+instinct lasts only during the period of lactation. As soon
+as the child begins to take different kinds of food, he ceases
+to be pleased with his mother’s milk, and may dislike it
+for the remainder of his life. Several adults to whom I have
+offered human milk would not even taste it, so disgusting
+did it seem to them. And yet the taste had nothing intrinsically
+disagreeable in it. Here again is an example
+of a strong instinct that changes completely.</p>
+
+<p class='c007'>Children often eat to repletion of some kind of substance,
+and for long afterwards that substance disgusts them instead
+of being coveted by them. It is said that apprentices to
+pastry-cooks and makers of sweetmeats are allowed at
+first to eat as much as they please. They soon come to have
+<span class='pageno' id='Page_283'>283</span>a profound dislike for the sweet things that children like
+so much.</p>
+
+<p class='c007'>A mother who adores her child, or a child who is extremely
+fond of sweetmeats cannot understand how any mother
+could dislike her offspring or any apprentice have a distaste
+for sweets. In the same way, human beings full of the
+desire for life, believe more easily in eternal life than in the
+possibility of an instinct of death. And yet the instinct
+of death seems to lie, in some potential form, deep in the constitution
+of man. If the cycle of human life followed its
+ideal course according to physiological function, then the
+instinct of death would appear in its time, after a normal
+life and an old age healthy and prolonged.</p>
+
+<p class='c007'>In reality, human life is subject from its very beginning
+to the pernicious disharmonies in the constitution of man.
+This evil influence increases with the passing of the years
+and leads to an old age ruined by abnormalities. It is not
+surprising that under such circumstances men wish neither
+to grow old nor to die. Old men, in spite of their attachment
+to life, do not attain the capacity to know all that is
+good in it, and die, in the fear of death, without having
+known the instinct of death. They may be compared with
+unhappy women who have married before their sexual instincts
+have awakened and who have died in childbirth,
+without ever having known the real joy of loving. Formerly,
+the number of women in such a case was large. In some
+parts of Abyssinia, girls married when they were still very
+young and before their physical development was mature.
+According to Hassenstein,<a id='r338'></a><a href='#f338' class='c014'><sup>[338]</sup></a> nearly one third of these young
+women died in childbirth. They quitted life before they
+had known the true sexual instinct. The advancement
+of civilisation and of medical knowledge has greatly reduced
+<span class='pageno' id='Page_284'>284</span>the number of such unhappy women. We must hope that
+the progress of knowledge will bring about a similar advance
+in relation to the instinct of death. With that progress,
+the number of men who will live until the instinct has
+been attained will become greater and greater.</p>

+
+<p class='c006'>Man, who is a descendant of some anthropoid ape, has
+inherited a constitution adapted to an environment very
+different from that which now surrounds him. Man is
+possessed of a brain very much more highly developed than
+that of his ancestors, and has entered on a new path in the
+evolution of the higher organisms. The sudden change
+in his natural conditions has brought about a large series
+of organic disharmonies which become more and more
+acutely felt as he becomes more intelligent and more sensitive.
+And thus there has arisen a number of sorrows which
+poor humanity has tried to relieve by all the means in its
+power. The disharmonies in the sexual functions have
+brought into existence attempted remedies of the strangest
+kind. The greatest disharmony of the constitution is that
+of the morbid nature of old age and the impossibility of
+reaching the instinct of natural death; this has produced
+childish and erroneous conceptions of the immortality of
+the soul and of the resurrection of the body, and many other
+<span class='pageno' id='Page_286'>286</span>strange doctrines that have been imposed upon us as revealed
+truth.</p>
+
+<p class='c007'>Human intelligence, in the course of its progressive evolution,
+has rebelled against these naïve palliatives. Finding
+the restoration of the much-desired harmony beyond its
+power, humanity became resigned to a passive fatalism,
+and believed even that the existence of man was a kind
+of bad joke, a <em>faux pas</em> in the evolution of sentient organisms.
+Exact science, developing slowly, but surely, has at last
+tried to master the situation. Moving step by step, passing
+from the simple to the complex and from the particular
+to the general, science has established a set of truths which
+all the world must accept.</p>
+
+<p class='c007'>Humanity in its misery has put question after question
+to science, and has lost patience at the slowness of the
+advance of knowledge. It has declared that the answers
+already found by science are futile and of little interest.
+From time to time it has preferred to turn back, and to
+delude itself with the beautiful mirages offered by religions
+and systems of philosophy.</p>
+
+<p class='c007'>But science, confident of its methods, has quietly continued
+to work. Little by little, the answers to some of
+the questions that have been set have begun to appear.
+Whence do we come? science has been asked unceasingly.
+Is not man a being unlike other beings, made in the image
+of God, animated with the divine breath, and immortal?
+No, science answers. Man is a kind of miscarriage of an
+ape, endowed with profound intelligence and capable of
+great progress. His brain is the seat of processes that are
+very complex, and much higher than those of other animals,
+but these functions are incompatible with the existence
+of an immortal soul.</p>
+
+<p class='c007'>Whither are we going? That question above all other
+<span class='pageno' id='Page_287'>287</span>things has absorbed the attention of man, and naturally
+so, for it is less important to know our origin than to know
+our destiny. Does death mean absolute extinction, or is
+it a gateway leading to a new and everlasting life? And
+if the latter alternative be untrue, how are we to face inevitable
+death?</p>
+
+<p class='c007'>Science cannot admit the immortality of the conscious
+soul, for consciousness is a function of special elements in
+the body that certainly cannot live for ever. Immortality
+exists only for very low organisms that renew their lives
+by repeated divisions with complete regeneration, and
+that have no highly developed consciousness.</p>
+
+<p class='c007'>Death brings absolute extinction, and it seems unbearable
+because of the condition in which it surprises us. It comes
+before man has finished his physiological development,
+and when the instinct of life is still strong.</p>
+
+<p class='c007'>Ever since man has begun to look a little beyond his
+daily and immediate wants, he has asked if there be a goal for
+his life, and what that goal may be. As he has generally
+failed to find such a goal, he has gone the length of believing
+life to be a mere accident, and of thinking it idle to seek a
+goal. He has formed depressing and pessimistic conclusions.
+Humanity may be compared to a boy that has not
+yet acquired the sexual instinct, but has asked the meaning
+of the reproductive organs. As these organs play no part
+in the functions of his life, he might easily think their
+existence not only absolutely useless but absurd.</p>
+
+<p class='c007'>Man, because of the fundamental disharmonies in his
+constitution, does not develop normally. The earlier
+phases of his development are passed through with little
+trouble; but, after maturity, greater or lesser abnormality
+begins, and ends in old age and death that are premature
+and pathological. Is not the goal of existence the
+<span class='pageno' id='Page_288'>288</span>accomplishment of a complete and physiological cycle,
+in which occurs a normal old age ending in the loss of the
+instinct of life and the appearance of the instinct of death.</p>
+
+<p class='c007'>The pessimistic school has often spoken of death as the
+true goal of human life. Schopenhauer,<a id='r339'></a><a href='#f339' class='c014'><sup>[339]</sup></a> for instance,
+said: “Death must really be regarded as the true goal of
+life; when it comes it at once adjusts all that has been preparing
+in the course of life.” Baudelaire<a id='r340'></a><a href='#f340' class='c014'><sup>[340]</sup></a> has exactly the
+same idea in his verse:</p>
+
+<div class='lg-container-b c022'>
+  <div class='linegroup'>
+    <div class='group'>
+      <div class='line'>“<span lang="fr">C’est la mort qui console, hélas! et qui fait vivre;</span></div>
+      <div class='line'><span lang="fr"><em>C’est le but de la vie</em>, et c’est le seul espoir</span></div>
+      <div class='line'><span lang="fr">Qui, comme un élixir, nous monte et nous enivre</span></div>
+      <div class='line'><span lang="fr">Et nous donne le cœur de marcher jusqu’au soir.</span>”</div>
+    </div>
+  </div>
+</div>
+
+<p class='c021'>“Alas! it is death that comforts and gives us life; it is the
+goal of our days, it is our only hope that like a wine goes
+to our head and makes us drunk, and puts heart into us
+to journey on till the night.”</p>
+
+<p class='c007'>The normal end, coming after the appearance of the
+instinct of death, may truly be regarded as the ultimate
+goal of human existence. But before attaining it, a normal
+life must be lived: a life filled all through with the feeling
+that comes from the accomplishment of function. Knowledge
+of the true goal of life clears up the problem and
+shows us the right conduct of life. In my first chapter,
+I tried to lay before the reader a summary of the views that
+have been held as to right conduct. Ever since the attempt
+has been made to discover a rational basis of morality,
+human nature, regarded essentially as good, has been taken
+as that basis. Religions and systems of philosophy, on the
+other hand, which have tried to find another foundation
+for morality, have regarded human nature as vicious at
+<span class='pageno' id='Page_289'>289</span>the roots. Science has been able to tell us that man, the
+descendant of animals, has good and evil qualities in his
+nature, and that his life is made unhappy by the evil qualities.
+But the constitution of man is not immutable, and
+perhaps it may be changed for the better.</p>
+
+<p class='c007'>Morality should be based not on human nature in its
+existing vitiated condition, but on human nature, ideal,
+as it may be in the future. Before all things, it is necessary
+to try to amend the evolution of the human life, that is to
+say, to transform its disharmonies into harmonies (<em>Orthobiosis</em>).
+This task can be undertaken only by science, and
+to science the opportunity of accomplishing it must be
+given. However, even in the most civilised countries,
+science is far from being in this ideal condition. Obstacles
+lie in its way and retard its advance.</p>
+
+<p class='c007'>To make the human constitution better, it would be
+necessary to know it thoroughly. How can we try to transform
+to a normal and physiological condition old age, at
+present utterly pathological, unless we first understand the
+most intimate details of its mechanism? Deeply rooted
+prejudices make it very difficult to examine the organs of
+the aged dead. The difficulties surrounding post-mortem
+investigations are almost insurmountable. According to
+the regulations enforced in France, autopsies cannot be
+made until twenty-four hours after death. An autopsy
+cannot be made except when the corpse has not been
+claimed by any relatives in the direct line, husband or wife,
+brothers, sisters, uncles, aunts, nephews, nieces. If kinsmen
+put in no claim, co-operative societies may take possession
+of the corpse and oppose the holding of an examination.
+Even when an examination has been permitted, it
+must extend only to “the ascertaining of exact facts, and
+this must be taken as excluding the mutilation of the corpse
+<span class='pageno' id='Page_290'>290</span>by the removal of any organ or portion of the anatomy,
+however interesting scientifically such material might be.”
+(Circular of the Director of “Assistance publique,” January
+20, 1900.<a id='r341'></a><a href='#f341' class='c014'><sup>[341]</sup></a>) It is easy to see that such regulations make
+extremely difficult the investigation of senile degeneration,
+and the search for means of preventing it, especially by the
+use of serums obtained after injecting emulsions of human
+organs. These difficulties in reality arise from the prejudice
+in favour of the existence of a life beyond the grave
+and a resurrection of the body.</p>
+
+<p class='c007'>Almost similar difficulties stand in the way of obtaining
+the bodies of old animals. Their owners prefer to keep
+animals, after they are useless, until they die, and to bury
+the bodies instead of devoting them to the scientific investigation
+that is so important to humanity.</p>
+
+<p class='c007'>As soon as we come to believe that the solution of the
+problems of human happiness will come not from religions
+nor from systems of metaphysical philosophy, but from
+exact science alone, the obstacles to progress will be removed.
+That scientific methods will redress the disharmonies of
+the human constitution is the more probable inasmuch as
+the old age of human beings was more physiological, and
+their death more natural, in earlier times than they are
+to-day.</p>
+
+<p class='c007'>The study of the human constitution not only denotes
+the real goal of our existence, but indicates to us what is
+meant by true culture and real progress.</p>
+
+<p class='c007'>In earlier chapters, I have shown that philosophers have
+recognised the existence in man of a tendency to culture
+and progress. But what do they mean by these two words?
+Attempts have been made to define them as clearly as
+<span class='pageno' id='Page_291'>291</span>possible, and Herbert Spencer, the greatest of living philosophers,
+has devoted a special essay to the subject. He examined
+those phenomena that he regarded as progressive,
+first in the inorganic world, next, in the world of living things,
+and, finally, in humanity. He regards as progressive only
+the changes that tend to increase human happiness, and it
+is precisely on account of that tendency that he regards them
+as progressive. In order to define progressive phenomena
+Spencer thinks it necessary to make parallel studies of
+them in man and the animal world. He finds that progress
+is marked always by a transformation from the simple and
+uniform to the complex; and that it produces constant
+differentiation, in the evolution of the planetary world,
+in the embryonic development of the individual, and in the
+societies of men and animals. But differentiation is not
+a complete account of progress, for in the latter must be
+included the change of the indefinite into the definite.
+Spencer identifies progress with evolution, and his well-known
+definition of evolution is, that it is “an integration
+of matter and concomitant dissipation of motion; during
+which the matter passes from an indefinite, incoherent
+homogeneity to a definite, coherent heterogeneity; and
+during which the retained motion undergoes a parallel
+transformation.” Such a formula embraces too much, so
+that he is rather vague, especially when he applies it to
+human affairs. Differentiation in itself is not the whole
+of progress. It is necessary in each concrete case to inquire
+into its limits and modifications.</p>
+
+<p class='c007'>The application of his theory of progress and evolution
+led Spencer, in his investigation of the basis of morality,
+to define human progress as the tendency towards a life
+as full and as long as possible. By fulness he means complexity,
+if I interpret his argument correctly. Civilised
+<span class='pageno' id='Page_292'>292</span>life as compared with savage life, is a realisation of progress.
+Civilised man, according to Spencer, uses food in a better
+regulated fashion, in accordance with the call and degree
+of his appetite; the food is of better quality, it is freed from
+contamination, is much more varied and is better prepared.
+The same differentiation distinguishes the clothing, the
+homes and so forth of civilised man. According to Spencer,
+all such progress helps real happiness, that is to say the
+fulness and the prolongation of life.</p>
+
+<p class='c007'>It is easy to see, however, that such an interpretation
+of progress is inexact, like the conception of the goal of life
+associated with it. If the complication of the mode of life,
+which is so marked in modern civilisation, is really the best
+way of reaching happiness, there are no reasons to arrest
+the tendency in that direction. If, on the other hand, my
+view be correct, that true progress consists in the elimination
+of the disharmonies of human nature and in the cultivation
+of physiological old age followed by natural death,
+the conditions for realising progress would be different and
+very clear. The great complexity of life in modern civilisation
+is a sign of progress according to Spencer, but I do not
+agree with him. Spencer speaks of the variety and preparation
+of food. It is certain that this complexity militates
+against physiological old age, and that the simpler food of
+uncivilised races is better. I do not wish to write an essay
+on domestic hygiene, and I shall be content with saying
+that most of the delicate dishes provided in the homes,
+hotels, and restaurants of the rich, stimulate the organs of
+digestion and secretion in a harmful way. It would be true
+progress to abandon modern cuisine and to go back to the
+simple dishes of our ancestors. One of the conditions that
+enabled the Jews of the earlier Biblical times to live longer
+than civilised people, was, beyond all doubt, the greater
+<span class='pageno' id='Page_293'>293</span>simplicity of their diet. True hygiene, which is in open
+disagreement with the elaborated art of cookery, is also
+opposed to the differentiation of modern dress and dwellings.
+Progress thus would consist in simplifying many sides of
+the lives of civilised people.</p>
+
+<p class='c007'>The luxury which has done so much harm to mankind,
+and which would be included in the formula, “passage
+from indefinite homogeneity to definite heterogeneity,”
+is founded not on a general law of evolution of the whole
+universe, but on a particular conception of life, quite
+different from mine according to which the rectifying of
+the abnormal human cycle to a normal cycle is the true
+goal of life.</p>
+
+<p class='c007'>Perhaps one of the oldest conceptions of life that has
+tended to luxury is to be found in the book of Ecclesiastes.
+Having reached the conclusion: “For in much wisdom
+is much grief: and he that increaseth knowledge increaseth
+sorrow” (i. 18), and having said: “Then I beheld all
+the work of God, that a man cannot find out the work that
+is done under the sun: because though a man labour to
+seek it out, yet he shall not find it, yea farther; though a
+wise man think to know it, yet shall he not be able to find
+it.”<a id='r342'></a><a href='#f342' class='c014'><sup>[342]</sup></a> Solomon laid down the rules of life as follows: “Go
+thy way, eat thy bread with joy, and drink thy wine with
+a merry heart: for God now accepteth thy works.”</p>
+
+<p class='c007'>“Let thy garments be always white; and let thy head
+lack no ointment.”</p>
+
+<p class='c007'>“Live joyfully with the wife whom thou lovest all the
+days of the life of thy vanity, which he hath given thee
+under the sun, all the days of thy vanity; for that is thy
+portion in this life, and in thy labour which thou takest
+under the sun.”</p>
+
+<p class='c007'><span class='pageno' id='Page_294'>294</span>“Whatsoever thy hand findest to do, do it with thy
+might; for there is no work, nor device, nor knowledge,
+nor wisdom, in the grave, whither thou goest.”<a id='r343'></a><a href='#f343' class='c014'><sup>[343]</sup></a></p>
+
+<p class='c007'>The wisdom of Solomon was to enjoy this life as much
+as possible, since man is unable to solve the problem of the
+goal of life. His precepts have been taken as a guide, and
+have led to an organisation of life that could only become
+more and more epicurean.</p>
+
+<p class='c007'>As soon as the goal of life has been seen clearly, luxury
+ceases to be true happiness as it hinders the making perfect
+of the normal cycle of human life. Young people, instead
+of abandoning themselves to all the pleasures because they
+have nothing before them but a sad prospect of morbid
+old age and death, ought to make ready for physiological
+old age and natural death. The apprenticeship certainly
+will be long. In our time the years of study already last
+much longer than occurred even a century ago. As the body
+of knowledge grows greater, the time to acquire it will
+become prolonged, but this period of preparation will serve
+as the prelude to ripe maturity and ideal old age.</p>
+
+<p class='c007'>Old age is repulsive at present, because it is an old age
+devoid of its true meaning, full of egoism, narrowness of
+view, incapacity and malignancy. The physiological old
+age of the future assuredly will be very different. In the
+societies of animals, especially as they occur among insects,
+the members show a high degree of differentiation. Some
+individuals are adapted to the reproductive functions, while
+others are sterile and are fitted for the care of the young
+and to supply the wants of the community. This differentiation,
+which is of social value, has arisen independently in
+different groups. Thus, in the societies of bees and ants the
+workers are sterile females, while in the case of termites,
+<span class='pageno' id='Page_295'>295</span>individuals of both sexes may be sterile. In the human
+race, evolution is following another path. There is no sign
+of the appearance of a sterile class; but, as the life of man
+is longer than that of insects, it is divided into two periods,
+a reproductive period and a sterile period. Old age, at
+present practically a useless burden on the community,
+will become a period of work valuable to the community.
+As the old man will no longer be subject to loss of memory
+or to intellectual weakness, he will be able to apply his
+great experience to the most complicated and the most
+delicate parts of the social life.</p>
+
+<p class='c007'>Young men are usually very bad politicians, and in
+countries where they take a large share in public affairs
+they do much harm because they are without the necessary
+practical knowledge. Their incapacity is clearly shown
+by the great changes in their political views as they advance
+in years and gain experience. In the future, old men will
+have charge of all complex and difficult social functions.
+Thus, vast improvements will be made in politics and in
+justice, which at present are defective because of their
+insufficient foundations.</p>
+
+<p class='c007'>As soon as every one has recognised the true goal of human
+life, and has assumed, as the ideal, the realisation of the normal
+cycle of life, a real guide to life will have been found. We
+shall know at least whither we are going, and as yet we are
+ignorant of that. We have wished to make life better,
+but we have not known how or for whom to make the
+attempt. Formerly it was assumed that, in the future, love
+would spread and become generalised. Family love had
+spread to the tribe and then had been transformed to patriotism;
+it was held that no obstacle stood in the way of its
+embracing all humanity. Such an idea was prevalent in
+the eighteenth century, and became a common ground of
+<span class='pageno' id='Page_296'>296</span>all systems of philosophy, morality and politics. But, since
+means of communication have been improved so vastly
+and since the most distant voyages are within the power
+of almost every one, the vague notion of “humanity” has
+been replaced by exact knowledge of the native savages
+in many parts of the earth. We have come to disbelieve
+in “humanity” in the old sense of the word, so great is the
+difference between savage and civilised peoples. And many
+modern theories have rejected the inclusion of the lower
+races in the sentiment of humanity. In the fifth chapter,
+I quoted the view of the moralist, Sutherland, on the advantages
+that have come about from the English seizure of the
+forests that belonged to the natives of Australia. Moreover,
+it is well known that a profound hatred exists between
+white men and black men in several parts of the earth,
+notably in America and the Antilles. Such instances
+could be multiplied.</p>
+
+<p class='c007'>How then are we to emerge from this difficulty? At
+what point is the love of the future to be stayed, if it cannot
+spread to all humanity?</p>
+
+<p class='c007'>In a recently published treatise on natural philosophy,
+Ostwald,<a id='r344'></a><a href='#f344' class='c014'><sup>[344]</sup></a> a very distinguished German physical chemist,
+has discussed this question. He calls good “the actions that
+made easier the existence of other men.” But to what other
+men are we to apply this rule? “What is the size of the
+circle of altruistic love,” asked Ostwald. “The general feeling,”
+he said, “is that it should cover the family and the nation.
+The feeling that it should cover all humanity appears to
+most of us as a theoretical demand rather than something
+practical. And thus have not most of us the tendency
+to limit our altruistic actions much more in the case of men
+beneath us than in the case of our social comrades (Stadesgenossen)?”
+<span class='pageno' id='Page_297'>297</span>According to this formula, moral action
+would not stretch beyond our compatriots, and humanity
+as a whole would be excluded from it.</p>
+
+<p class='c007'>Here we have entered on a problem relating to the
+principles of normal life. In former times, religion was the
+chief bond among men. Later on, religion gave way to
+patriotism, which in default of anything better still holds
+its place. Community of language unites the individuals of
+a nation, but the advance of civilisation has undermined
+the foundation of that source of differentiation. Naturally,
+when a number of men spoke only one and the same language,
+great solidarity was the result, as ideas spread only
+by language. But such a monoglottism is not the end of
+human progress. As means of communication have improved,
+the nations have been brought in contact with each
+other. The knowledge of foreign languages is an elementary
+necessity of modern life. And so the bonds of nationality
+certainly will become looser, in this respect following the
+bonds of family. The dislike that we have to people whose
+language we do not understand, becomes changed into a
+feeling of unity with them as soon as we can understand
+them. In that respect an active development is in progress,
+and we shall have to seek out some new principle on which
+to base international solidarity. A good deal has been
+made of the possession by different nations of the same
+culture, but the vagueness of the phrase has not been
+realised. Recognition of the true goal of life and of
+science as the only means by which that goal may be
+attained would form an ideal on which men might unite;
+they would group themselves around that, as in former
+days men were held together by religion.</p>
+
+<p class='c007'>I think it extremely probable that the scientific study
+of old age and of death, two branches of science that may
+<span class='pageno' id='Page_298'>298</span>be called <em>gerontology</em> and <em>thanatology</em>, will bring about great
+modifications in the course of the last period of life. All
+that we know on these subjects confirms my view. But will
+it lead to the development of an instinct of death? That
+instinct lies deep in the roots of the human constitution?
+Will the means be found to bring it to the surface? Has
+not the enormous period during which it has remained
+latent led to its atrophy? The science of the future
+alone can answer that question. But the persistence of
+organs and structures that are extremely ancient, as for
+instance, the survival of the mammary glands in males and
+of the vermiform appendage in anthropoid apes and man,
+gives us the hope that the instinct of natural death may
+emerge from its latent condition when old age has become a
+normal process.</p>
+
+<p class='c007'>The mammary glands of males are functionless rudiments.
+They must be interpreted as vestiges of organs that were
+more highly developed in remote ancestors among which both
+sexes gave milk to nourish the young. This function exists
+in a latent condition in the males of living mammals. Extremely
+rare cases have existed in which males possessed
+large glands secreting enough milk to feed the young.
+These males, it is true, had the genital organs either very
+badly developed or in a condition approaching hermaphroditism.<a id='r345'></a><a href='#f345' class='c014'><sup>[345]</sup></a>
+But in other authentic cases (perfectly developed)
+he-goats and rams have been known to provide milk in
+considerable quantities, whilst married men have suckled
+children with milk secreted by unusually developed glands.
+It is stated that the secretion of milk can be excited by
+stimulation of the nipples.<a id='r346'></a><a href='#f346' class='c014'><sup>[346]</sup></a> Such examples of the reappearance
+<span class='pageno' id='Page_299'>299</span>of a latent property that has been lost for untold ages
+are extremely important.</p>
+
+<p class='c007'>Probably actual cases of the instinct of natural death
+in man are as rare as instances of the secretion of milk by
+males. But favouring circumstances and some education
+of the instinct of death would probably reawaken it and
+develop it fully. There is much work to be done before
+so great an object can be achieved. But it is the peculiar
+feature of science to be eager for much labour, while religions
+and systems of metaphysical philosophy are content with
+passive fatalism and silent resignation. The mere hope of
+being able to solve the great problems of humanity in the
+more or less distant future brings much satisfaction. When
+Tolstoi, agonised by the impossibility of solving the great
+problems, and haunted by the fear of death, asked if the
+love of our children is not able to sooth our souls, he found
+that such a hope was vain. “What is the good,” he said,
+“of rearing children who will soon find themselves in the
+same difficult position as their parents?” “Why should
+they live? why should I love them and protect them and
+foster them? Is it that they may come to the same despair
+as I am in myself or else grow imbecile? As I love them,
+I do not wish to hide the truth from them, for each step in
+knowledge will lead them nearer to it. But the truth is—death.”
+I can understand that many persons would
+abstain from having children if they had come to these
+pessimistic conclusions.</p>
+
+<p class='c007'>The point of view that I have exposed in this book will
+make life more possible. Our generation has no chance
+of attaining physiological old age and normal death; but
+it may take real consolation from the thought that those
+who are now young may advance several steps in that
+direction. It may reflect that each succeeding generation
+<span class='pageno' id='Page_300'>300</span>will get closer and closer to the solution and that true
+happiness one day will be reached by mankind.</p>
+
+<p class='c007'>The slow advance to happiness will demand many sacrifices.
+Already, men of science sacrifice their health and
+sometimes their life to reach the solution of some important
+problem, as for instance, to clear up a medical question,
+and so be ready to heal or to save the lives of their fellows.</p>
+
+<p class='c007'>Before it is possible to reach the goal, mankind must be
+persuaded that science is all-powerful and that the deeply
+rooted existing superstitions are pernicious. It will be
+necessary to reform many customs and many institutions
+that now seem to rest on enduring foundations. The
+abandonment of much that is habitual and a revolution
+in the mode of education will require long and painful effort.</p>
+
+<p class='c007'>Definition of the goal of human existence will bring great
+precision to the principles of morality. True policy will
+have to be reared on new foundations. The politics of to-day
+are in the condition in which medicine still remained
+in days long past. In the old days any one was allowed
+to practise medicine, because there was no medical science
+and nothing was exact. Even at the present time, among
+less civilised people, any old woman is allowed to be a midwife.
+In some cases the mother attends the labour of her
+daughter, or (as for instance in a caste of natives in Malabar),
+it may be the mother-in-law who does the duty. Very often
+friends act as midwives. Among more civilised races,
+differentiation has taken place, and childbirths are attended
+by women of special training, who are midwives by diploma.
+In the case of nations still more civilised, the trained midwives
+are directed by obstetric physicians who have specialised
+in the conducting of labour. This high degree of
+differentiation has arisen with, and has itself aided, the
+progress of obstetric knowledge.</p>
+
+<p class='c007'><span class='pageno' id='Page_301'>301</span>Politics, as they exist to-day, correspond to the early
+stages of obstetric practice. Every adult male is thought
+fit for exercising functions so difficult as those of an elector
+or a juryman. The only excuse for this condition is that
+political science is in its infancy. When sociology is more
+advanced, there will come about a differentiation like that
+in medicine. When that has taken place, old persons who
+have acquired great experience, and who because of their
+physiological constitutions have preserved all their faculties,
+will give most valuable services to the society of the future.</p>
+
+<p class='c007'>In the progress towards the real goal of life, men will lose
+much of their liberty, but will receive in exchange a new
+feeling of solidarity. As knowledge becomes more and
+more extensive and exact, freedom to neglect it will be
+more and more limited. Formerly any one was at liberty
+to teach that whales were fish; but now that it has been
+proved that whales are mammals, the mistake is not to be
+pardoned. Since medicine has become more of an exact
+science, the liberty of doctors has been restrained. Practitioners
+have already been sentenced for neglecting antisepsis
+and asepsis. Other forms of freedom, such as the freedom
+to neglect vaccination against smallpox, to spit on the floor,
+or to let dogs run loose without being muzzled, are worthy
+of savage days and will cease as civilisation advances.</p>
+
+<p class='c007'>On the other hand, the knowledge that the goal of human
+life can be attained only by the development of a high degree
+of solidarity amongst men will restrain actual egotism. The
+mere fact that the enjoyment of life according to the precepts
+of Solomon is opposed to the goal of human life will
+lessen luxury and the evil that comes from luxury. Conviction
+that science alone is able to redress the disharmonies
+of the human constitution will lead directly to the improvement
+of education and to the solidarity of mankind.</p>
+
+<p class='c007'><span class='pageno' id='Page_302'>302</span>In progress towards the goal, nature will have to be consulted
+continuously. Already, in the case of the ephemerids,
+nature has produced a complete cycle of normal life
+ending in natural death. In the problem of his own fate,
+man must not be content with the gifts of nature; he must
+direct them by his own efforts. Just as he has been able
+to modify the nature of animals and plants, man must
+attempt to modify his own constitution, so as to readjust
+its disharmonies.</p>
+
+<p class='c007'>Breeders form a conception of the ideal result when they
+are about to attempt the production of some new variety
+which shall be pleasing esthetically and of service to man.
+Next, they study the existing individual variations in
+animals and plants on which they wish to work, and from
+which they will select with the minutest care. The ideal
+result must have some relation to the constitution of the
+organisms selected.</p>
+
+<p class='c007'>To modify the human constitution, it will be necessary
+first, to frame the ideal, and thereafter to set to work with
+all the resources of science.</p>
+
+<p class='c007'>If there can be formed an ideal able to unite men in a
+kind of religion of the future, this ideal must be founded
+on scientific principles. And if it be true, as has been
+asserted so often, that man can live by faith alone, the faith
+must be in the power of science.</p>

+<p class='c007'>This work deals with the problem
+of personality, especially as raised by
+William James and M. Bergson. If a
+man imagines himself bound, in deference
+to science or psychology, to deny
+the existence of personality, he commits
+himself to saying “I do not exist.” If
+he shrinks from that absurdity, he must
+accept personality as a reality: a person
+is both a subject who knows others and
+an object of others’ knowledge. The
+bond, however, which holds persons,
+human and divine, together, cannot be
+merely intellectual: it must be emotional
+as well as intellectual—the bond of love.</p>

+<p class='c006'>By Jean Finot</p>
+
+<p class='c007'>Author of “Problem of the Sexes,” etc.</p>
+
+<p class='c007'>Translated from the French by
+Mary J. Safford</p>
+
+<p class='c007'><em>8º. $1.75 net</em></p>
+
+<p class='c007'>The author considers a subject, the solution of
+which offers more enticement to the well-wisher
+of the race than the gold of the Incas did to the
+treasure-seekers of Spain, who themselves doubtless
+looked upon the coveted yellow metal,
+however mistakenly, as a key to the happiness
+which all are trying to find. “Amid the noisy
+tumult of life, amid the dissonance that divides
+man from man,” remarks M. Finot, “the
+Science of Happiness tries to discover the
+divine link which binds humanity to happiness
+through the soul and through the union
+of souls.” The author considers the nature
+of happiness and the means of its attainment,
+as well as many allied questions.</p>
