NATURAL SELECTION, In that most delightful of printed books, the “ Conversations of Goethe with Eckermann and Soret,” there is an amusing anecdote which shows how distinctly the great master real- -ized the importance of the question of the origin of species. The news of the French Revolution of July, 1830, had just reached Weimar and set the whole town in commotion. In the course of the afternoon, says Soret, “I went around to Goethe’s. ‘ Now,’ exclaimed he to me, as I entered, ‘ what do you think of this great event? The volcano has come to an eruption; everything is in flames, and we have no longer a transaction with closed doors!’ ‘Terrible affair, said I, ‘but what could be expected under such outrageous circum- stances, and with such a ministry, otherwise than that the whole would end with the expulsion of the royal family ?’ My good friend,’ gravely returned Goethe, ‘we seem not to understand each other. I am not speaking of those creatures there, but of something quite different. I am speaking of the contest, so important for science, between Cuvier and Geoffroy Saint-Hilaire, which has just come to an open rupture in the French Academy!’” At this unex- pected turn of the subject poor Soret knew not what to say, B 2 4 COSMIC PHILOSOPHY. lpr. 1. and for some minutes, he tells us, his thoughts were quite at a standstill. | The anecdote well illustrates the immeasurable superiority of Goethe over Comte in prophetic insight into the bearings of the chief scientific question of the immediate future. While Comte was superciliously setting aside the problem of man’s origin, as a problem not only insoluble but utterly devoid of philosophic value even if it could be solved, the great German poet and philosopher was welcoming the outbreak of this famous contest on questions of pure morphology, as conducive to the speedy triumph of the development theory, for which he himself had so long been waging battle. But events were hastening that triumph even more rapidly than Goethe could have anticipated. In December 1831, only a few weeks before Goethe was laid in the grave, Mr. Darwin set out upon that voyage around the world, in the course of which he fell in with the facts which suggested his theory of the origin of species. The history of the investigation is a memorable one,—worth noting for the illustration it gives of the habits of a truly scientific mind. On his return to England, in 1837, Mr. Darwin began patiently to collect all kinds of facts which might be of use in the solution of the problem,—“ how is organic evolution caused?” It was only after seven years of unremitting labour that he went so far as to commit to manuscript a brief sketch of his general conclusions, of which the main points were communicated to his friends Sir Charles Lyell and Dr. Hooker. A less wise and sober speculator than Mr. Darwin would now at once have rushed into print, A thinker less thoroughly imbued with the true scientific spirit would probably have suffered from not publishing his views, and profiting by the adverse criticisms of contemporary observers. It is a striking illus- tration of Mr. Darwin’s patience and self-restraint that he continued fifteen years longer to work assiduously in testing the weak and strong points of his theory, before presenting —_ on) NATURAL SELECTION. F it to the public, And it is an equally interesting illustration of his thoroughly scientific temperament that, after so many years of solitary labour, he should have been so little carried away by the fascinations of his own hypothesis as to foresee clearly all the more valid objections which might be urged against it. After a careful perusal of the recent literature of the subject, and especially of the skilful work of Mr. St. George Mivart, it still seems to me that the weightiest objections which have yet been brought to bear on the Dar- winian theory are to be found in Chapters VI—IX. of Mr. Darwin’s own work, where they are elaborately and in most cases conclusively answered. To such a marvellous instance of candour, patience, and sobriety, united with the utmost boldness of speculation, the history of science can show but few parallels. In 1858, a fortunate circumstance caused Mr. Darwin to break his long silence, and to give to the public an exposition of the results of his researches, Mr. Wallace, who had been for several years engaged in studying the natural history of the Malay Archipelago, had arrived at views concerning the origin of species quite similar to Mr. Darwin’s, and in 1858 he sent Mr, Darwin an essay on the subject, which in August of the same year was published in the Journal of the Linnzan Society. ‘Sir Charles Lyell and Dr. Hooker now earnestly advised Mr. Darwin to publish his own views; and in 1859 the memorable treatise on the “Origin of Species” was given tothe world. It would, however, be incorrect to rate Mr. Wallace’s merits, in the discovery of the law of natural selection, so high as Mr. Darwin’s. They do not stand on precisely the same level, like Adams and Leverrier with reference to the disco- very of the planet Neptune. Mr. Wallace, indeed, thought out independently all the essential points of the theory, and stated it in a way which showed that he understood its wide-reaching importance; but being a much younger man 6 COSMIC PHILOSOPHY, (pr. 11. than Mr. Darwin, and having begun the investigation at a much later date, he by no means worked it out so elabo- rately. Nor is it likely that, with an equal length of time at his command, he could have succeeded in producing a work comparable in scientific calibre to the “Origin of Species.” His lately published collection of essays, while showing unusual powers of observation and rare acuteness in the' application of his theory to certain special classes of phenomena, nevertheless furnishes convincing proof that in breadth and depth of scientific attainment, as well as in philosophic capacity, he is very far inferior to his great coadjutor. In his preface, indeed, Mr. Wallace hastens to acknowledge, with a modest self-appreciation as rare as it is admirable, and especially rare in such cases, that his strength would have been quite unequal to the task which Mr. Darwin has accomplished. As Prof. Haeckel somewhere observes, it was quite fortunate for the progress of science that Mr. Darwin received such a stimulus to the publication of his theory; since otherwise he might perhaps have gone on several years longer, observing and experimenting in seclusion. The almost im- mediate acquiescence of the majority of naturalists in Mr. Darwin’s views, shows that in 1859 the scientific world was fully prepared for them. The flimsiness of the special- creation hypothesis was more or less clearly perceived by a large number of biologists, who were only withheld from committing themselves to the derivation theory by the cir- cumstance that no satisfactory explanation of the process of development had been propounded. No one had assigned an adequate cause for such a phenomenon as the gradual evolution of a new species; and sundry attempts which had been made in this direction were so obviously futile as to txcite both distrust and ridicule. Lamarck, for example, placing an exaggerated stress upon an established law of biology, contended that “desires, by leading to increased cH, X.] NATURAL SELECTION. ” actions of motor organs, may induce further development of such organs,” and that, consequently, animals may become directly adapted through structural changes to changes in their environment. We shall see, as we continue the dis- cussion, that such directly adaptive changes really take place; but Lamarck ill understood their character, and indeed could not have been expected to understand it, since in his day dynamical biology was in its earliest in- fancy... By insisting on volition as a chief cause of adaptive change, the illustrious naturalist not only left the causes of vegetable variation unexplained, but even in the zoological department laid open the way for malicious misrepresen- tations which the uninstructed zeal of theological adversaries has gladly transferred to the account of Mr. Darwin. Some time ago a clergyman in New York, lecturing about Dar- winism, sarcastically alluded to “the bear which took to swimming, and so became awhale.” Had this worthy person condescended to study the subject about which he thought himself fit to enlighten the public, he would soon have dis- covered that his funny remark is not even a parody upon any opinion held by Mr. Darwin. In so far as it is appli- cable to any opinion ever held by a scientific writer, it may perhaps be accepted as a parody, though at best a very far- fetched and feeble one, of the hypothesis of Lamarck. It is now time to explain what the Darwinian theory is. At the outset we may observe that while it is a common error to speak of Mr. Darwin as if he were the originator of the derivation theory, the opposite error is not unfrequently committed of alluding to him as if he had contributed nothing to the establishment of that theory save the doctrine of natural selection. Mr. Mivart habitually thus alludes to him. In fact, however, Mr. Darwin’s merits are twofold. He was the first to marshal the arguments from classification, * Lamarck also tried to explain organic development metaphysically, as the continuous manifestation of an “ inherent tendency ” toward perfection. 8 COSMIC PHILOSOPHY. (Pr. 1, embryology, morphology, and distribution, and thus fairly to establish the fact that there has been a derivation of higher forms from lower; and he was also the first to point out the modus operandi of the change. The first of these achieve- ments by itself would have entitled him to associate his name with the development theory; though it was only by the second that the triumph of the theory was practically assured. Just as, in astronomy, the heliocentric theory was not regarded as completely established until the forces which it postulated were explained as identical with forces already known, so the development theory possessed comparatively little value as a working hypothesis so long as it still remained doubtful whether there were any known or knowable causes sufficient to have brought about the phenomena which that theory assumed to have taken place. It was by pointing out ade- quate causes of organic evolution that Mr. Darwin established the development theory upon a thoroughly scientific basis. As Lyell explained all past geologic phenomena as due to the slow action of the same forces which are still in, action over the earth’s surface and beneath its crust, so Mr. Darwin, in explaining the evolution of higher from lower forms of life, appeals only to agencies which are still visibly in action. ‘Whether species, in a state of nature, are changing or not at the present time, cannot be determined by direct observation, any more than the motion of the hour-hand of a clock could be detected by gazing at it forone second. The entire period 1 <‘Tf we imagine mankind to be contemplated by some creature as short- lived as an ephemeron, but possessing intelligence like our own—if we imagine such a being studying men and women, during his few hours of life, and speculating as to the mode in which they came into existence ; it is manifest that, reasoning in the usual way, he would suppose each man and woman to have been separately created. No appreciable changes of structure eccurring during the few hours over which his observations extended, this being would probably infer that no changes of structure were taking place, or had taken place ; and that from the outset, each man and woman had pos- sessed all the characters then visible—had been originally formed with them, oy pee naturally be the first impression,”’—Spencer, Principles of Biology, vol, i. p. 338. -_ cu.x.) NATURAL SELECTION. 9 which has elapsed since men began to observe nature sys- tematically, is but an infinitesimal portion of the period requisite for any fundamental alteration in the characteristics of a species. But there are innumerable cases in which species are made to change rapidly through the deliberate intervention of man. In the course of a few thousand years, a great number of varieties of plants and animals have been produced under domestication, many of which differ so widely from their parent-forms that, if found in a state of nature, they would be unhesitatingly classified as distinct species, and sometimes as distinct genera. Modifications in the specific characters of domesticated organisms are the only ones which take place so rapidly that we can actually observe them ; and it therefore becomes highly important to inquire what is the agency which produces these modifications. That agency is neither more nor less than selection, taking advantage of that slight but universal variation in organisms implied by the fact that no two individuals in any species are exactly alike. If man, for example, wishes to produce a breed of fleet race-horses, he has only to take a score of horses and select from these the fleetest to pair together: from among the offspring of these fleet pairs he must again select the fleetest ; and thus, in a few generations, he will obtain horses whose average speed far exceeds that of the fleetest of their undomesticated ancestors. It is in this and no other way that our breeds of race-horses have becn pro- duced. In this way too have been produced the fine wools of which our clothing is made. By selecting, generation after generation, the sheep with the finest and longest wool, a breed of sheep is ultimately reared with wool almost generically different from that of the undomesticated race. In this and no other way have the different races of dogs—the greyhound, the mastiff, the terrier, the pointer, and the white-haired Eskimo—been artificially developed from two or three closely allied varieties of the wolf and jackal. The mastiff and 10 COSMIC PHILOSOPHY. [pr. 1, blood-hound are more than ten times as large as {he terrier, and, if found in a state of nature, they would perhaps be classed in distinct genera, like the leopard and panther, whose differences are hardly more striking. Yet the ancestral races from which these dogs have been reared differed but slightly from each other. The different breeds of dogs vary in the number of their toes, teeth, and vertebre, in the number and disposition of their mamme, in the shape of their zygomatic arches, and in the position of their occiputs; although dogs have not been selected with refereuce to these peculiarities, about which uninstructed men neither know nor care, but only with reference to their sveed, fleetness, strength, or sayacity. In the case of domestic pigeons, where man has been to a great extent actuated by pure fancy in his selections, the divergences are still more remarkable. All domestic pigeons are descended from a single species of wild pigeon; yet their differences, even in bony structure, in the internal organs, and in mental disposition, are such as charac- terize distinct genera, and to describe them completely would require a large volume. Pigs, rabbits, cows, fowl, silk-moths, — and hive-bees furnish no less instructive evidence; and the development of the peach and the almond from a common stock, and of countless varieties of apple from the sour crab, may be cited, out of a hundred examples, to show what pro- digies artificial selection has accomplished in the modification of vegetal organisms. , Now Mr. Darwin’s great achievement has been to show that a similar process of selection, going on throughout the organic world without the knowledge or intervention of man, tends not only to maintain but to produce adaptive alterations in plants and animals. The process is a simple one, when once we have the clew to it. All plants and animals tend to increase in a high geometrical ratio, The old problem of the nails in the horse’s shoe teaches us what an astounding affair is a geometrical rate of in- Pe oy PO STEN ye ee eee ha ae on. x.] NATURAL SELECTION. rt crease; but when we consider the reproductive capacity of insects and plants, the nails in the horse’s shoe are left no- where. When Arctic travellers tell us that the minute proto- coccus multiplies so fast as to colour blood-red many acres of snow in a single night, such a rate of increase appears astonishing. But it is a mere trifle compared to what would happen if reproduction were to go on unchecked. Let us take the case of a plant which yields one hundred seeds yearly, and suppose each of these seeds to reach maturity so as to yield its hundred offspring in the following year: in the tenth year the product would be one hundred quintillions* of adult plants! As this is one of those figures before which the imagination stands hopelessly baffled, let us try the effect of an illustration. Supposing each of these plants to be from three to five inches in length, so that about twenty thousand would reach an English mile, the total length of the number © just mentioned would be equal to five million times the radius of the earth’s orbit. The ray of light, which travels from the sun to the earth in eight minutes, would be seventy-six years in passing along this line of little plants! And in similar wise, it might be shown of many insects, crustaceans, and fishes, that their unchecked reproduction could not long go on without requiring the assimilation of a greater quantity of matter than is contained in the whole solar system. We may now begin dimly to realize how prodigious is the slaughter which unceasingly goes on throughout the organic world. For obviously, when a plant, like the one just cited, maintains year by year a tolerable uniformity in its numbers, it does so only because ou the average ninety-nine seeds perish prematurely for one that survives long enough to produce other seeds. A single codfish has been known to tay six million eggs within a year. If these eggs were all to become adult codfishes, and the multiplication were to * According to the American system of numeration, One hundred thousand Willions, according to the English system, 12 COSMIC PHILOSOPHY, [prem continue at this rate for three or four years, the ocean would not afford room for the species. Yet we have no reason to suppose that the race of codfishes is actually increasing in numbers to any notable extent. With the codfish, as with animal species in general, the numbers during many succes- sive generations oscillate about a point which is fixed, or moves but slowly forward or backward. Instead of a geometrical increase with a ratio of six millions, there is practically no marked increase at all. Now this implies that out of the six million embryo codtish a sufficient number will survive to replace their two parents, and to replace a certain small proportion of those contemporary codfishes who leave no progeny. Perhaps a dozen may suffice for this, perhaps a hundred. The rest of the six million must die. We may thus understand what is meant by the “ struggle for existence.” Battles far more deadiy than those of Gettysburg or Gravelotte have been incessantly waged on every square mile of the earth’s life-bearing surface, since life first began. It is only thus that the enormous increase of each species has been kept within bounds. Of the many offspring produced by each plant and animal, save in the case of those highest in the scale, but few attain maturity and leave offspring behind them. The most perish for want of sustenance, or are slain to furnish food for other organisms. There is thus an unceasing struggle for life—a competition for the means of subsistence—going on among all plants and animals. In this struggle by far the greater number succumb without leaving offspring, but a few favoured ones in each generation survive and propagate to their offspring the - qualities by virtue of which they have survived. Thus we see what is meant by “ Natural Selection.” The organisms which survive and propagate their kind are those which are best adapted to the conditions in which they live: so that we may, by a legitimate use of metaphor, personify Nature as a mighty breeder, selecting from each generation cH, x.] NATURAL SELECTION, 13 those individuals which are fleetest, strongest, most sagacious, lions with supplest muscles, moths with longest antenne, mollusks with hardest shells, wolves with keenest scent, bees with surest instinct, flowers with sweetest nectar,—until, in the course of untold ages, the numberless varieties of organic _ life have been produced by the same process of which man now takes advantage in order to produce variations to suit his own caprices. Between natural selection and selection by man there is, however, one important difference. Selection by man tends _to produce varieties adapted to satisfy human necessities or inclinations, and it has no direct reference to the maintenance of the species. Such abnormities as the pouter and tumbler pigeons could not be sustained in a state of nature ; and hence, when doinesticated animals are turned loose, they are _ apt to revert to something like their ancestral type,! else they are exterminated by races better adapted to wild life. But natural selection, working with the sternest of methods, saves from the general slaughter only those individuals which can best take care of themselves, and thus maintains each species in adaptation to its environment. The wonderful harmonies in the organic world, which a crude philosophy explained as the achievement of creative contrivance, are therefore due to the continued survival of the fittest and the continued slauchter of the less adapted plants and animals. Now if the geography and meteorology of the earth were ever-constant, if the nature of the soil, the amount of moisture, the density of the atmosphere, and the intensity of solar radiance were everywhere to remain forever unaltered, and if each race of plants and animals were always to remain confined to one limited area, the survival of the fittest would simply maintain unaltered any given aspect of the beings constituting the organic world. All variations on either side 1 This fact, which has often been alleged by superficial critics as an obstacle to the Darwinian theory, is thus in reality implied by that theory. 14 : COSMIC PHILOSOPHY. [pr. 11, of tlie well-adjusted mean would be incessantly cut off by natural selection, and species would be immutable. It is needless to say that no such state of things has ever existed. Constant change has been the order of things ever since our planet first became fit to support organic life. No part of the earth’s surface is now, or ever has been, at rest. Con- tinents are rising and sinking, seas are growing deeper and shallower, soils are constantly altering in chemical composi- tion, rivers are ever changing their beds, solar radiance is ever gaining or losing in intensity, according to the earth’s ever-varying position in space, the density and moisture of the air are continually increasing and diminishing, and every species of plant and animal is continually pressing upon the limits of the area within ‘which it is confined. All these changes are going on to-day, and have been going on during millions of ages. Though so slight as to be recognized only by the most careful observation during the period covered by human history, these changes have during longer periods sufficed to submerge every continent and perhaps to make dry land of every sea and ocean on the face of the globe. They have raised mountains like the Andes and the Himalayas at the rate of a few inches per century; they have converted ex- tensive tropical swamps into the desert of Sahara; they have repeatedly covered Europe and North America with glaciers ; and they have hidden beneath solid rocks vast treasures of carbon stealthily purloined from the dense atmosphere of an older age. Since such changes have ever been going on, it follows that organisms have been unable to remain constant and live. A race of animals or plants in which no individuals ever varied would sooner or later inevitably be exterminated, leaving no progeny to fill its place. Observation shows, however, that there is no such race. The members of each species are ever slightly varying, but, so long as the environment remains constant, natural selection prevents the variations from cu. x.) NATURAL SELECTION. 15 accumulating on either side of the mean which is most advantageous to the species. When the environment changes, if certain variations on one side of the established mean tend to bring the individuals which manifest them into closer adaptation to the new environment, these individuals will survive in the struggle for life, and thus the average character of the species will be slightly altered. No two bears have just the same amount of hair, no two moths have just the same length of proboscis, no two antelopes are exactly matched in fleetness. Now if increasing cold renders a thicker covering useful to the bear, or if the lengthening of a flower- calyx, due to a slight change in soil or quantity of sunlight, renders a longer proboscis useful to the moth, or if the immigration of a carnivorous animal makes it necessary for antelopes often to run for their lives, then in each generation the thickest-coated bears, the longest-tongued moths, and the fleetest antelopes will survive. Every individual variation in the direction of a heavier coat, a longer sucker, or a structure better adapted for fleeing will give its owner the advantage in the incessant struggle for life, and these peculiarities will be oftenest inherited, while individuals which do not vary, or which vary in the wrong direction, will have to migrate or die. The student of natural history, who realizes, however dimly, the prodigious complexity of the relations of the various species of animals and plants to each other, will perceive that the amount of variation thus preserved and enhanced must in the course of long ages become enormous. If a grain of sand were each year added to an ant-heap, it would in course of time become as large as Chimborazo. But these changes, directly caused by natural selection, are greatly 1 It is thus one of the great merits of the theory of natural selection, that it accounts for the phenomena of eatinction of species, —which formerly could only be accounted for by the gratuitous and utterly indefensible hypothesis bf periodical catastrophes or cataclysms, 16 COSMIC PHILOSUPHY, 3 [Pr. 11. aided and emphasized by other changes indirectly produced by correlation of growth, and also by what is called the law of use and disuse. By correlation of growth, or internal equilibration, we mean the effect produced upon any part of the organism by change in a related or neighbouring part. Let us suppose that it becomes advantageous to some feline animal, like the ancestor of the lion, to have large and power- ful jaws. Since no two of our leonines would have jaws of exactly the same size and strength, natural selection would preserve all the strong-jawed individuals, while the weak- jawed individuals would succumb in the struggle for life. In the course of many generations our race of leonines would possess on the average much larger and stronger jaws than at the period at which we began to consider it. But greater weight of jaw entails increased exertion of the muscles which move the jaw, so that these muscles, receiving more and more blood, will become permanently increased in size and power. The portions of the skull into which the jaw- bones fit will likewise receive an extra strain, and will con- sequently increase in rate of nutrition and grow to a larger size, so that the shape of the whole head will be altered. This increased weight of the head, and the increasingly violent activity of the muscles which move the jaws, entails a greater strain upon the vertebrze which support the head, and upon the cervical muscles which move it from side to side. The heightened nutrition of these bones and muscles will add to their weight, so that the shoulders and chest will be affected. There will be a tightening of the tendons, and probably a perceptible alteration in the relative lengths of the different bones and muscles throughout the anterior part of the body ; and these changes, altering the animal’s centre of gravity, will inevitably cause other compensating changes in the rest of the body. The legs, shoulders and haunches will be modified. Alterations in the weights bearing upon ‘he chest will affect the erowth of the lungs and the aeration a eee ee eee OS eee eee St eS * ee Pe ed 0 ee a 6 ee Cr eh oe a ert aie cH. X.] NATURAL SELECTION. VI of the blood. And the stomach, intestines, and various secreting glands will respond to the requirements of all these nutritive changes. While, lastly, such deep-seated variations cannot fail to influence the nervous system of the animal, and to modify somewhat its temperament and its modes of life. To illustrate the effects of use and disuse, let us reconsider the antelopes, of whom natural selection has so long pre- served the swiftest and most quickly frightened individuals that they now rank among the fleetest and most timid of mamuals. If all the lions and other swift carnivora of Africa were to become extinct, so that antelopes would no longer have to run for their lives, the slower and less easily alarmed individuals would begin to be preserved in as great numbers as the swifter and more timid ones, so that by and by the average speed and timidity of the race would be diminished. In all this we see merely the effects wrought by unaided natural selection. But it is a fundamental law of biology that functions are maintained at their maximum only through constant exercise. Freed from savage enemies, our antelopes would less frequently use the muscles concerned in running, and would less often exercise the mental faculties concerned in the rapid perception of approaching danger. Inevitably, therefore, they would, after several generations, diminish in speed, and become less alert and less timid. Here we see the effects of what is called the law of use and disuse. But to these we should also have to add the effects of correlation of growth. Decrease in speed, involving decrease in muscular tonicity, and rendering possible the assimilation of less concentrated food, would seriously modify the nutrition of the entire organism. The digestive tract would probably be enlarged, and larger and lazier bodies could not fail to be produced, voth by the direct influence of the nutritive processes, and because natural selection would no longer necessitate the slaughter of all clumsy-bodied individuals. Thus in course of time the breed of antelopes VOL. IL. Cc 18 COSMIC PHILQSOPHY, Dash by Me would become so thoroughly altered as to constitute a distinct species from their graceful, swift, and timid ancestors. It is in just these ways that New Zealand birds, freed by insular isolation from the attacks of mammalian enemies, have grown large and clumsy, and have lost the power of flight which their partly-aborted wings show that they once possessed. By the same kind of illustration we may form a rough notion of the way in which a single species bifurcates into two well-defined species. Suppose a race of ruminants to have been living in Africa before the introduction of car- nivora, and suppose that, for sundry reasons, the vitality of the race was but little affected by moderate variations in the sizes of its individuals, so that while some were com- paratively light and nimble, others were comparatively large and clumsy. Now introducing upon the scene the common ancestor of the lion and the leopard—by immigration either from Asia or from some other adjacent territory now sub- merged—let us note some probable features of the complex result. First, as regards the attacked ruminants, it is likely that in course of time the lightest and swiftest individuals, habitually taking refuge in flight, would have greatly increased both in fleetness and in timidity; the largest and most clumsy of the species, unable to save themselves by fleeing, would often be forced to stand and fight for their lives, and would thus ultimately have gained in size, strength, and courage; while those who were neither nimble enough to get out of the way nor strong enough to fight successfully would have all been killed off. And thus, after a while, by perpetual destruction of the means and preservation of the extremes, we should get two kinds of ruminant as different from one another as the antelope which escapes by his fleetness and cauticus timidity, and the buffalo which boldly withstands the lion and not unfrequently conquers or repulses him. Secondly, let us olserve what must have been going on all \he while with the attacking carnivora. The lighter and less i ee ON ee ye ee . on. x.] NATURAL SELECTION, 19 powerful of these would find manifest advantage in crouching amid dense foliage and springing down upon unwary victims passing below. The larger and more powerful individuals would more frequently roam about the open country, attack- ing the larger ruminants and giving chase to the nimbler ones, and would thus increase in strength and fieetness. And thus there would be initiated such differences of size and habit as characterize the leopard and the hon. It must be borne in mind that this is a purely hypothe- tical illustration, which does not pretcnd to give a complete account of the complex process, I have no idea that the differentiation between antelopes and buffaloes, or between lions and leopards, was accomplished in any such straight- forward way as this. But while unduly simplifying the case, the illustration is undoubtedly sound in principle. No doubt the lion is so strong and so swift because only the strongest and swiftest lions have been ‘able to prey at once upon buffaloes and upon antelopes. No doubt the antelope is so swift and so timid because only the swiftest and most quickly-frightened antelopes have been enabled to get away from the lion, and to propagate their kind. And no doubt in the process above described, we get a partial glimpse of some of the essential incidents in the past careers of these races. All the foregoing illustrations unite in enforcing the con- clusion that the direct and indirect effects of natural selection are by no means limited to slight or superficial vhanges in organisms. The student of physiology well knows that no change, however seemingly trivial, which ensures the sur- vival of the organism in its fierce struggle for existence, can fail in the iong run to entail so many other changes as to modify, more or less perceptibly, the entire structure. Even such a slight change as an increased thickness of the woolly coat of a mammal may, by altering the excretory power of the skin, affect the functions of the lungs, liver, and kidneys, and thus indirectly increase or diminish the size of the c 2 20 COSMIC PHILOSOPHY. (pr. 1 animal, which in turn will modify its speed, its muscular development, its mental faculties, and its habits of life. Having thus briefly indicated the capacity of the theory of natural selection for explaining the most general phenomena of organic variation, let us in conclusion observe how admir- ably it explains certain special phenomena, which do not otherwise admit of scientific explanation. For evidence of the signal success with which Mr, Darwin has explained such otherwise unaccountable facts as the dimorphism of certain flowers, the existence of neuters or sterile females among bees and ants, the odoriferous glands in mammals, the calcareous shells of mollusks, the heavy carapace of the tortoise, the humps of the camel, the amazingly complicated © contrivances through which orchidaceous plants are fertilized by insects, the slave- making instinct of certain ants, the horns of male ruminants, atid countless other phenomena ; for all this, I must refer to Mr. Darwin’s various works. From the mass of phenomena to which the theory of natural selection has been satisfactorily applied, I will only select as an illustration the case of colour, in the animal and vegetal kingdoms. Until after the publication of Mr. Darwin’s speculations, the colours of plants and animals had never been made the subject of careful and philosophical study. So far as any hypothesis was held concerning these phenomena, it was the vaguely conceived hypothesis that they are due to the direct action of such physical conditions as climate, soil, or food. But there are fatal objections to such an explanation. When Dr. Forbes Winslow, in his work on the “ Physiological Influence of Light,” tells us that “the white colour of ani- mals inhabiting the polar regions is attributable to the absence of intense sunlight,” it is an obvious objection that the polar regions are not pre-eminent for darkness. Though within the limits of the arctic circle the sun is below the horizon for six months together, it is none the less for the cH. Xx. | NATURAL SELECTION. 21 other six months above the horizon; and though its slanting rays do not cause excessive heat in the summer, the prolonged glare of light, intensified by reflection from the snow and ice, is described as peculiarly intolerable. The summer ought to tan the polar bears as much as the winter can bleach them. And to this it may be added that the Eskimos and Green- landers, living under the polar circle, are not bleached. Several other facts, alike incompatible with the direct action of physical agencies, are mentioned by Mr. Wallace. While wild rabbits, for instance, are always tinted grey or brown, the same rabbits, when domesticated, give birth to white and black varieties, though there has been no change either in climate or in food. The case is the same with domestic pigeons. But even supposing that the most general features of animal colouring could be explained on this hypothesis— which they cannot be—there would still remain the more remarkable cases of tree-frogs, which resemble bark, and of the so-called leaf-butterflies, which when at rest are indistin- guishable from leaves; and the existence of such cases isa stumbling-block in the way of all theories save the theory of natural selection. _ For according to the theory of natural selection each species of animals will be characterized by that shade of colour which is most advantageous to the species in the struggle for exist- ence. Now, as Mr. Wallace observes, “ concealment is useful to many animals, and absolutely essential to some. Those whicn have numerous enemies from which they cannot escape by rapidity of motion, find safety in concealment. Those which prey upon others must also be so constituted as not to alarm them by their presence or their approach, or they would soon die of hunger.” In striking harmony with this general principle, we find that the great majority of animals are so coloured as best to escape notice, and that animals which are not protectively coloured are animals whose habits of life are such as to enable them to dispense with secrecy. The polar ug COSMIC PHILOSOPHY, [er. 1 bear is white, as the California bear is grey and the Hindustan bear black, because with a coat thus coloured it can best escape notice and secure its prey. -The polar hare has a per- manent coat of white ; but the alpine hare, the arctic fox, and the ermine, which do not live amid perpetual snow, have coats that are white in the winter only. Arctic owls, falcons, and buntings are. coloured snowy white; and the ptarmigan is white in winter, while “its summer plumage go exactly harmonizes with the lichen-covered stones among which it delights to sit, that a person may walk through a flock of them without seeing a single birds” In the sandy deserts of NorthernAfrica, all birds, without exception, all snakes and lizards, and all the smaller mammals, are of a uniform sandy colour. The camel is tinted like the desert in which he lives, and the same is true of the antelope and the Australian kangaroo. The tawny lion, says Mr. Wallace, “is a typical example of this, and must be almost invisible when sidings upon the sand or among desert rocks and stones.” His brother, the tiger, “is a jungle animal, and hides himself among tufts of grass or of bamboos, and in these positions the vertical stripes with which his body is adorned must so assimilate with the vertical stems of the bamboo, as to assist _ greatly in concealing him from his approaching prey. How remarkable it is that besides the lion and tiger, almost all the other large cats are arboreal in their habits, and almost all have ocellated or spotted skins, which must certainly tend to blend them with the backeround of foliage; while the one exception, the puma, has an ashy brown uniform fur, and has the habit of clinging so closely to a limb of a tree, while waiting for his prey to pass beneath, as to be hardly distinguishable from the bark.”! Such nocturnal animals as owls, goat-suckers, mice, bats, and moles are dusky-coloured. In tropical forests, where the trees are laden with green foliage all the year round, we find brilliant green 1 Wallace, Natural Sclection, pp. 49, 53. cH. x.} NATURAL SELECTION. 23 pigeons and parrots; while the northern snipe resembles the marshy vegetation in which it lives, and the woodcock, with its variegated browns and yellows, is inconspicuous among the autumn leaves.' Arboreal iguanas are tinted leafy green ; and out of many species of tropical tree-snakes there is but one which is not green, and this kind conceals itself during the daytime in holes, Flat fish, like the skate and flounder, are coloured like the gravel beneath them. Fishes which live among gorgeous coral reefs are magnificently tinted. The brilliant red hippocampi of Australia dwell among sea-weed of the same colour. And numerous other examples from the vertebrate sub-kingdom are given by Mr. Wallace, from whose remarkable essay the examples here given are culled. Before going farther, let us note how completely these interesting phenomena are in harmony with the theory ot natural selection. The variability of the hues of domestic animals descended from a monotonously-coloured wild species, shows that there is no direct physiological necessity for the production of animals of a single given style of colouring. But it is tolerably obvious that in the struggle for existence the most conspicuous among those animals which serve as food for others will be the soonest detected, killed, and eaten; while in general the most conspicuous carnivorous animals will be the most easily avoided, and hence will be the most likely to perish for lack of sustenance. And while it is not universally true of the higher animals, as it is of the lower animals and plants, that a much greater number perish than survive, the destruction of life is nevertheless so great that the fate of each creature must often depend upon apparently trivial circumstances, The explanation would therefore be satisfactory, even if protective shades 1 Tho general principle is well stated by Emerson, in this pretty quatrain : ** He took the colour of his vest From rabbit’s coat and grouse’s breast 3 For as the wild kinds lurk and hide, So walks the huntsmun unespied.” » 24 CUSMIC PHILOSOPHY, [pr. 1 of colouring could be regarded as circumstances of slight importance,—which they cannot. Since, therefore, it is natural selection which keeps up the protective hues of animals, by killing off all save the least conspicuous individuais, we may understand why it is that animaJ3 which have for several generations been domesticated no longer retain, without considerable deviation, their pro- tective style of colouring. Freed from the exigencies of wild life, there is no longer an imperious need for concealment, and hence the unfavourably coloured individuals survive like the rest, and variety appears among members of the same species. In the cat family, which appears to have been originally arboreal, there is a strong tendency to the produc- tion of stripes and spots. In the lion, which is not arboreal, and in the puma, owing to the peculiarity above mentioned, these variegated markings have been almost wholly weeded out by natural selection. But in the domestic cat, along with these spots and stripes which occasionally show its blood-relationship with the leopard and tiger, we more often meet with colours not paralleled among the wild species; now and then we see cats which are coal-black or snowy white. Cows, horses, sheep, dogs, and fowl, furnish parallel examples. ‘Thus too we may understand why the sable and the Canadian woodchuck retain their brown fur during the winter; for the one can subsist on berries, and is far more agile than any of its foes, while the other lives in burrows by the riverside and catches small fish that swim by in the water. And thus we may understand why it is that in the case of birds which build open nests, the female is dull coloured like the nest; while on the other hand, the females of birds which build domed nests are often as brightly coloured as the males. 1 The variegated marking usually appears, however, in lion-cubs; thus showing that the variegated colouring of the leopard and tiger is relatively primary, while the monotonous colouring of the adult lion is relatively secondary. cH. X.] NATURAL SELECTION. 25 Turning now to the insect world, we find a vast abundance of corroborative proof. Among the tiger-beetles examined by Mr. Wallace in the Malay islands, those which lived upon wet mossy stones in mountain brooks. were coloured velvet green ; others, found for the most part on dead leaves in the forest, were brown ; others again, “ never seen except on the wet mud of salt marshes, were of a glossy olive so exactly the colour of the mud as only to be distinguished when the sun shone,” by casting a shadow. “In the tropics there are thousands of species of insects which rest during the day clinging to the bark of dead or fallen trees; and the greater portion of these are delicately mottled with grey and brown tints, which though symmetrically disposed and infinitely varied, yet blend so completely with the usual colours of the bark, that at two or three feet distance they are quite indistinguishable.” Moths, which when resting expose the upper surfaces of their wings, have these dull- coloured. Butterflies, on the other hand, which rest with their wings raised perpendicularly and laid together so as to show only the under surfaces, have the upper surfaces brilliantly coloured, while the exposed under surfaces are dusky and inconspicuous, or even marked in imitation of leaves. Mr. Wallace describes an East Indian butterfly whose wings are superbly tinted with blue and orange: this butterfly is a very swift flyer and is never known to settle save among the dead leaves in the dry forests which it frequents. When settled, with its wings raised, it imitates a shrivelled leat suv perfectly that even the keen eye of the naturalist can hardly detect it. This protective colouring is found throughout the whole immense order to which belong “rasshoppers, crickets, and locusts; the most remarkable instance being furnished by the so-called “ walking-leaf,” to which no description can do justice. On the other hand, hornets, bees, and wasps, which are protected by their stings, are brilliantly but not in general protectively coloured. Bugs 26 - COSMIC PHILOSOPHY. [pr. 11, and ground-beetles emit a disagreeable, pungent smull, and they are often conspicuously coloured. But the most wonderful of all are the cases of protective mimicry. The heliconide are among the most beautiful of South American butterflies. Being never eaten by birds, on account of a nauseous liquid which exudes from them when touched, they are not only very lazy dyers, but have the under sides of their wings as gorgeously tinted as the upper side, so that they can be seen from quite a ‘ong distance. From the same cause they are prodigiously numerous, swarming in all the tropical forests. Now it is obvious that if another butterfly, not protected by a disagreeable odour or taste, were to resemble the heliconia in colouring, it would be as efficiently protected as by imitating a dead leaf or dry twig; provided that there were but few of these butterflies among a large number of heliconias. For, as Mr. Wallace says, “if the birds could not distinguish the two kinds externally, and there were on the average only one eatable among fifty uneatable, they would soon give up seeking for the eatable ones, even if they knew them to exist.” Now along with the heliconide there does, in fact, live a distinct family of butterflies, the pieridee, most of which are white, and which are anatomically as distinct from the heliconide as a lion from a buffalo. But of these vieride there is one genus, the leptalis, which exactly resembles the heliconias in external appearance. So close is the resemblance that such expert naturalists as Mr. Bates and Mr. Wallace have been repeatedly deceived by it at the time of capture. Moreover, each species of this genus leptalis is a copy of the particular species of heliconia which lives in the same district. Every band and spot and fleck of colour in the heliconia is accurately reproduced in the leptalis; and besides this, the lazy mode of flight is also imitated. While in point of numbers, we find about one leptalis to a thousand heliconias. Nor is this the only instance. So pre-eminently favoured are these beautiful ee, We cH. X.] NATURAL SELECTION. | 27 insects by their disgusting taste, that they are exactly imitated by at least three genera of diurnal moths. In other parts of the world similar phenomena have been noticed. The relationship of the leptalis to the heliconia is repeated in India, in the Philippine Islands, in the Malay archipelago, and in various parts of Africa; the protected insect being, in all these cases, very much less numerous than the insect whose colours it mimics. In similar wise, bees and wasps are often imitated by beetles, by flies and even by moths, For further details I must refer to Mr. Wallace’s essay, which is a singularly beautiful specimen of inductive reason- ing. The facts already cited are quite enough to sustain the general conclusion that the colours of animals are in the main determined by the exigencies of the struggle for existence. Where it is for the advantage of an animal to be concealed, as in the great. majority of cases, its colour, whether brilliant or sombre, is such as to protect it. But where the animal is otherwise adequately protected—either by its peculiar habits, by a sting, a disgusting odour or taste, or a hard carapace— and where it is not needful for it to be hidden from the prey upon which it feeds, then there is usually no reference to protection in the colour of the animal. In some of these cases, however, a very conspicuous colouring .becomes pro- tective—as in the case of the jet-black toad which Mr. Darwin saw in La Plata, which emitted a poisonous secretion, and which, when crawling over the sandy plain, could not -ail to be recognized by every passing creature as an object to be avoided. In many cases the gorgeous tints of the otherwise protected male animal are due to what is called “sexual selection,”— to the continual selection of the more beautiful males by the females. To this cause is due the magnificent plumage of the male bird of paradise; and Mr. Darwin would similarly explain the brilliant colours of many male butterflies. In his work on the “Descent of Man” may be found an account 28 COSMiC PHILOSOPITY. [PT. 11 of the elaborate observations which have Jed to these con- clusions. Without feeling it necessary to insist upon the validity of all the special explanations contained in that work, we must admit that the general theory is substantiated by a superabundance of inductive evidence. And when this kind of selection is taken in connection with the need for protective concealment, we have the means of explaining by far the greater part of the colouring found in the animal kingdom. The colours of the vegetal kingdom have, to a considerable extent, been no less satisfactorily explained. “Flowers do not often need protection, but very often require the aid of insects to fertilize them, and maintain their reproductive powers in the greatest vigour. Their gay colours attract insects, as do also their sweet odours and honeyed secretions; and that this is the main function of colour in flowers is shown by the striking fact that those plants which can be perfectly fertilized by the wind, and do not need the aid of insects, rarely or never have gaily-coloured flowers.”? Returning for one moment to the case of animals, which are usually benefited by concealment but sometimes by conspicuousness, let us note Prof. Shaler’s ingenious explana- tion of the rattlesnake’s rattle. The existence of this appendage has long been a puzzle to philosophical naturalists, and Darwinians have been repeatedly challenged to account for the formation or preservation by natural selection of an organ assumed to be injurious to the species, The difficulty has lain in the assumption, too hastily made, that the noise of the rattle must be prejudicfal to the snake by fore- warning its enemies or prey of its presence, and thus giving the enemies time for sudden attack, and allowing the prey to escape. On the theory of natural selection, the preservation of the species must entail the atrophy of such an organ, or, rather, must prevent its origination, unless the 1 Wallace, Natural Selection, p. 262, Pe Ee et |e ae eee ee cn, x.] NATURAL SELECTION, 29 damage occasioned by it be more than compensated by some utility not hitherto detected. Prof. Shaler’s hypothesis, how- ever, suggests the possibility that this whole speculation is fundamentally erroneous. Far from being injurious to the snake, by serving to warn its prey, it would appear that the rattle may be directly useful by serving as a decoy. Prof. Shaler has observed that the peculiar sound of the rattle is a very close imitation of the note emitted by a certain cicada common in American forests frequented by rattlesnakes; and according to his ingenious suggestion, the bird, hearing the note and thinking to make a meal of the cicada, advances upon its own destruction, becoming the eaten instead of the eater. If this be true, there may be data here for explaining some of the alleged phenomena of fascination, so far as rattlesnakes are concerned; and another case will be added to the numerous cases now on record in which certain animals have acquired, for utility’s sake, peculiarities charac- teristic of totally different species. I should be more inclined, however, to adopt quite a different interpretation of the rattlesnake’s rattle. As hinted above, the general law that animals are benefited by concealment has some important exceptions, In many cases, when an animal is especially noxious, it is for his advantage to be conspicuous, that enemies may recognize him at a distance and keep away from him. Thus,as we have seen, while grasshoppers, moths, end butterflies (on the exposed under-surfaces of their wings) | are usually so coloured as best to escape notice, on the other hand, bees and wasps, which are protected by their stings, and many beetles, which are protected by a noxious taste or odour, are apt to be conspicuously coloured. And the jet- black toad of La Plata is a still better example. Now a zattlesnake is unquestionably a very noxious animal, and so dangerous to its enemies that they will always do well to keep out of its way. Moreover, the death-wound inflicted by it, though usually very sure, is somewhat slow in operation; 30 COSMIC PHILOSOPHY. [er. 1. so that in a fierce struggle it will often happen that its action is not prompt enough to preclude a return of compliments fatal to the snake. When a tiger tears open the jugular vein of his enemy, the enemy is placed hors de combat at once; but when the rattlesnake has bitten, there is nothing to prevent the foe from employing his few remaining moments in tearing the serpent to pieces. Hence the rattlesnake must be peculiarly benefited by an apparatus which serves as a signal to warn enemies of his presence, and to keep them from attacking him. His more formidable enemies, belonging chiefly to the mammalian class, are certainly intelligent enough to profit by such warning and shun the danger; and as it is plainly for the snake’s advantage to avoid even a conflict, it is clear that he is practically helped even less by his terrible bite than by his power of threatening a bite. This explanation seems to me quite sound in principle. Yet if we adopt it, there is nothing to prevent us from giving due weight also to Prof. Shaler’s suggestion. The success with which the note of the cicada is counterfeited by the rattle is a point to be more fully determined by further ybservation. And if it turns out that the rattle fulfiis the double purpose of alarming sundry animals that are hostile and of enticing sundry others that are good for food, it will not be the first case in which it has happened that a structure useful in one way has also become useful in another way. The question is an interesting one, and valuable if only because it reminds us of the danger of reasoning too con- fidently, from @ priori premises, about matters the due elucidation of which requires careful study of the details of the every-day life of animals. It is one of the great merits of the theory of natural selection: that it has directed so many naturalists, with eyes open, into this fruitful field of inquiry. It is because it so well illustrates the wealth of suggestive- ness in Mr, Darwin’s theory, that I have ventured upon thir Oe Ws eee tS. 2 ae 5 Sea ee on, x.] NATURAL SELECTION, 31 digression. To the general validity.of that theory, or even to the validity of the more special hypothesis concerning the uses of concealment or of cunspicuousness, the success o. the foregoing explanation is not essential,—since its possible inadequacy may very well be due to the incompleteness of our grasp upon all the details of this particular case. But, returning from this digression to our main thesis, and con- sidering the general significance of the phenomena of colour, we see that, in addition to those most general phenomena of organic life which demand for their explanation the Dar- winian theory, there is at least one special class of pheno- mena which that theory is competent to explain even in minute details. And there are other special classes of phenomena to which it has been applied with equally re- markable success. But when a theory, deduced from the observed general facts of organic life, and invoking no agencies but such as are known to be in operation, is found on trial to account for such an enormous mass of special facts, for which no other valid explanation has been pro- pounded,—we may well say of it, as Laplace said of his owu Nebular Hypothesis, that the chances in favour of its being a true explanation are many thousand million to one. CHAPTER XL TWO OBJECTIONS CONSIDERED, WHEN an objection to a complex theory in any department of science is so extremely obvious as to seem at first sight fatal to the theory, it is unwise to urge it in argument until we have very thoroughly considered the matter. Men like Laplace and Goethe, Spencer and Darwin, in framing their theories of evolution, are indeed liable to overlook difficulties which are so unobtrusive as to be detected only after pro- longed observation; but they are very unlikely to overlook difficulties which are so conspicuous as to occur at once to the minds of a hundred general readers. When, therefore, a reader of average culture, who has perhaps never seriously bent his mind to the question of the origin of species, and who is very likely unacquainted with the sciences which throw light upon that subject, finds himself immediately confronted by difficulties in a theory which men of the highest learning and capacity have spent a quarter of a cen- tury in testing, common prudence should lead him to con- tinue his study until he has made sure that the difficulty is not due to his own ignorance rather than to the shortcomings of the theory. This wholesome caution is too seldom maui- fested by literary reviewers, many of whom, in criticizing Mr. Darwin's theory without having duly read his works, oH. XI] TWO OBJECTIONS CONSIDERED, 33 allege certain objections as being quite obvious to all intelli- gent people, save to the one-sided speculator who is supposed to have ignored them. In Mr. Darwin’s case, this mode of treatment is peculiarly impertinent, since even the less ob- vious objections to the theory of natural selection were for the most part foreseen and answered in the first edition of the “Origin of Species,’—a book to which, as to an arsenul of scientific facts, one must still resert who would deal intel- ligently with the latest criticisms directed against the theory. The most obvious objection to the Darwinian theory is the paucity, or, as it is often incorrectly alleged, the absence, of transitional forms in the various sedimentary strata. This is at first sight a weighty objection against the doctrine of natural selection, according to which the progress has been effected by infinitesimal increments ; although it is of no force against the doctrine. of derivation, as held by Mr. Mivart, who rejects the maxim Natura non facit saltum, and maintains that progress has been effected by sudden jumps, occurring at rhythmical intervals. Mr. Mivart’s suggestion, however, cannot be entertained as a scientific hypothesis so long as it alleges no physical agencies competent to effect the sudden jumps from one specific form to another; nor does the com- parative paucity of transitional forms in a fossil state afford any reason for our adopting it. A brief consideration will show us that the fact is entirely consistent with the theory of progress by minute variations. In the first place, let us note that in general intermediate transitional forms must be the soonest killed off in the struggle for existence; and that, especially, where two strains or varieties become further differentiated into true species, it is the extreme forms which multiply at the expense of those which are intercalated between them. Here, as on a former occasion, our comprehension of the argument will be facilitated by a reference to the analogous set of phenomena which occur during the process of lin- VOL, II. DB 34 COSMIC PHILOSOPHY. [pr. 1 cuistic differentiation, It is held by most philologists that all languages in the tertiary or amalgamative stage of development must have previously existed in the secondary or agglutinative s{age,—and, at a yet earlier period, in the ‘primary or juxtapositive stage, of which the Chinese is a still living example. Against this view M. Renan has urged the absence or paucity of transitional forms connecting one class of languages with another. Now in answering M. Renan’s objection, I have begun by showing, from a con- sideration of the Romanic dialects, that the difficulty is only imaginary. “A language like Latin, spread. over a vast space of country in imperfectly civilized times, in- evitably breaks up into a host of local patois. Hach secluded rustic community has its own style of pronunciation, its own choice of words and syntactical devices, its own method of contracting or otherwise modifying its expressions. And although the inhabitants of any given town can usually communicate with these of the next town, the slight differences accumulate until intercourse between distant places is no longer practicable. In such a state of things we find plenty of transitional dialects, as the Genoese and Provengal between Italian and French, and the Balearic and Catalan between French and Spanish. The Tuscan can understand the Genoese, the Genoese can understand the dweller in Piedmont, the Piedmontese can understand the Vaudois, the Vaudois can understand the Lyonnais, and so on until we come to Paris; but the Tuscan and the Parisian cannot understand each other. Now the progress of civilization in each country tends to kill out the patois, elevating that variety of the language which has been made the vehicle of the dominant literature to supremacy over the more provincial forms. Increased facilities of com- munication, and the growth of large centres of population, and commercial as well as literary activity, end by making the inhabitants of all parts of the country speak and write cH. X1.] TWO OBJECTIONS CONSIDERED, 35 more and more like those of its intellectual metropolis. And in this way the intermediate dialects slowly disappear, leaving two languages with thoroughly distinct individuali- ties, like Italian and French.”! Now even here, as I go on to show, the relationships among the dialects have become sufficiently obscured—owing to disappearance of connecting links—to alloy M. Raynouard to maintain the paradox that the modern Romanic languages are descended, not directly from the Latin, but from the old Provengal. And in such countries as Hindustan, the processes of di- vergence, and accompanying obliteration, have gone on to such an extent that Bengali has been mistaken for a non- Aryan language. Here in the domain of language we see that competition is most severe and destructive between closely allied forms, and that the extremes will vigorously flourish long after the short-lived means have been crushed out of existence. The maxim Jn medio tutissimus tbis does not apply to such cases. We have now to observe that among the phenomena which natural history deals with, a quite similar process goes on. First we may note, with Mr. Darwin, that “as the species of the same genus usually have, though by no means in- variably, much similarity in habits and constitution, and always in structure, the struggle will generally be more severe between them, if they come into competition with each other, than between the species of distinct genera. We see this in the recent extension over parts of the United States of one species of swallow having caused the decrease of another species. The recent increase of the missel- thrush in parts of Scotland has caused the decrease of the song-thrush. How frequently we hear of one species of rat taking the place of another species under the most different climates! In Russia the small Asiatic cockroach has every- 1 “The Genesis of Language,” North American Review, Oct. 1869, pp. 834, 335. D 2 36 COSMIC PHILOSOPHY. [Pr. 11, where driven before it its great congener. In Australia the imported hive-bee is rapidly exterminating the small sting- less native bee. One species of charlock has been known to supplant another species; and so in other cases. We can dimly see why the competition should be most severe between allied forms, which fill nearly the same place in the economy of nature; but probably in no one case could we precisely say why one species has been victorious over another in the great battle of life.” } For our present purpose, however, it is not needful that we should be able to accomplish the latter task, which would require a knowledge of the minutiz of the organic world such as is not likely to be possessed by anyone for a long time tocome. It is enough for us to note that the ordinary process of competition, among organisms as among dialects, tends to kill out the means much sooner than the extremes, Still more clear will this become, if we recur to one of the hypothetical illustrations given in the preceding chapter. It was there shown that, in the case of a group of ruminants hitherto isolated from carnivorous foes, and in which different strains or varieties have begun to establish themselves, a newly-arriving incident force, in the shape of strong and swift* carnivora, will at once tend to exterminate all the intermediate forms, while the extremes will not only be indefinitely preserved, but will become yet more widely different from each other. Now this hypothetical case is probably a fair sample of a very large proportion—perhaps the majority—of the cases in which specific variations have been rapidly accumulated and persistently fixed. It is by no means likely that variation has gone on throughout the past with a uniform pace; but there must rather have been immensely long periods of comparative stability, alter- nating with relatively brief periods, during which newly- ‘ntroduced sets of circumstances have tended to enhance 1 Origin of Species, 6th edit., p. 59 ee ry ‘ CH, XI.] TWO OBJECTIONS CONSIDERED. 37 and accumulate variations on either side of a hitherto established mean. Such a conclusion is implied by the theory of natural selection, according to which specific vari- ation occurs, not in conformity to some mysterious law of progress uniformly operating, but only in conformity to some more or less conspicuous alteration in the sum- total of the conditions of existence. It follows, therefore, that in general, when incipient varieties are differentiated into well-marked species, the number of intermediate forms must be immeasurably smaller than the numbers of forms contained in the resulting species to which they serve as the transition. During epochs of rapid divergence, the means may all be extinguished after a few hundred generations, while the generations of the ex- tremes which persist thereafter may be numbered by tens of thousands. Suppose, for example, two great islands sepa- rated by a shallow sea. During long ages, while the floor of this intervening sea is constantly rising, the specific changes occurring on either island may be quite few and unimportant, and such fossil records as are left will indicate a general per- sistence of type. But when in course of time the process of elevation has converted this intervening channel into an isthmus connecting the two islands, there must inevitably ensue a marked change in the conditions of existence in both regions, Extinction will go on at a relatively rapid pace; and, as above illustrated, this extinction must ordi- narily result in the disappearance of intermediate forms and the preservation of extremes. After a while this process must result in the establishment of an approximate equili- brium among the forms of life over both areas, such ,as formerly obtained over each area separately. And thus fora long time to come, the specific changes occurring will again be few and unimportant. Thus we see graphically illustrated the truth that, in com- parison with the myriads of individuals comprising the well- 38 COSMIC PHILOSOPHY. [pr. 1% defined species which propagate themselves through long ages with relative stability of character, the number of inter- mediate individuals which ever come into existence must be relatively small. We have next to note that, even of this relatively small number of individuals, a still smaller rela. tive number are likely to leave after death a permanent fossil record of their existence. In the first place it is only by a rare combination of cir- cumstances that any plant or animal gets fossilized at all. The chances were nearly infinite against the preservation of any of the very earliest organisms, with their soft and speedily decaying textures. The higher land animals, on the other hand, owe their occasional preservation to the accidents of dying in sheltered caves, or of being covered with blown sand or peat-moss, or of being frozen in Arctic ice. ‘Trees with solid trunks, littoral and marine animals, especially crustaceans and shell-covered mollusks, are more likely to be preserved than other organisms. But, in the second place, the majority of the organisms once fossilized are afterwards destroyed along with the sedimentary strata which contain them. Since there have been several enormously long alter-. nating periods of elevation and of subsidence, it follows that all the older sedimentary strata must have been metamor- phosed by volcanic heat. These oldest rocks have sunk to a depth of six or eight miles, down below the ocean-floor, where they have been metamorphosed by the heat of the molten liquid below, and whence they have again been slowly shoved up above water-level, with all traces of their organic contents obliterated. This process must have occurred so many times as to have destroyed all but the later records of lite. The title “ paleozoic,” formerly applied to the Silurian rocks, is a misnomer. It was formerly supposed that there were no fossil-bearing rocks below the Silurian. But within a few years the Cambrian and Laurentian strata have been discovered, carrying us back into an antiquity nearly twice as SESSA RT SS Ps Re RE cu. XI] TWO GBJECTIONS CUNSIDERED. 39 great as that to which we had reached with the Silurian rocks; and it is now generally admitted that cven the Laurentian strata are modern compared with the beginnings of life upon our globe. But this is not all. Along with the immensely long ceologic rhythms, which have thus entailed the periodic metamorphosis of strata, there have been going on minor rhythms, resulting in the alternate deposit and denudation of fossil-bearing strata. Each of the sedimentary strata now surviving was deposited during an epoch of subsidence, and since its elevation to its present position has been more or less denuded. Now it is only during epochs of subsidence that permanent fossil-bearing strata can be deposited. During epochs of elevation the newly-formed sedimentary deposit is rapidly disintegrated by the action of coast-waves; and even those thin deposits which are made during an epoch of sub- sidence are in the next-recurring epoch of elevation soon worn away. It is thus only the thicker strata deposited during an epoch of subsidence which have preserved for our inspection a few specimens of the organisms living at the time when they were deposited. But in close juxtaposition to this comes the remarkable fact that the most rapid variation ameng specific forms must take place during epochs of elevation. For since the only variations preserved by natural selection are those which bring the organism into closer adaptation to its environment ; and since in most cases the organic environment of any group of organisms, comprising its enemies, competitors, and prey, is a much more important factor of change than its inorganic environment, comprising climate and soil; it follows that those periods during which groups of organisms, hitherto isolated, are gradually brought into contact with one another, must be the periods most favourable for specific change. The most rapid variation, attended by the greatest frequency of transitional forms, will therefore occur during those epochs of 40 COSMIC PHILOSOPHY, (Pr. 1, elevation when archipelagos are being converted into con- tinents, and when shallow parts of the sea, hitherto divided by deep channels, are getting practically united together by the diminishing depth of the channel. During such periods it is not only the inorganic agencies of climate and soil which will be altered; the organic environment of each group of organisms will be immensely increased in extent and heterogeneity. The struggle for existence will increase in violence, and there will be an increased amount both of variation and of extinction, We are thus driven to the remarkable conclusion, not only that each system of fossiliferous strata now remaining has been preceded and followed by systems destroyed as fast as they were formed, but also that the systems thus destroyed coincided with the periods which must have been richest in transitional forms. But notwithstanding the extreme imperfection of the geolo- gical record, and notwithstanding these special difficulties in the way of finding transitional forms, such forms are frequently met with. Indeed it may be asserted, as one of the most significant truths of paleontology, that extinct forms are almost always intercalary between forms now existing. Not only species, genera, and families, but even orders of con- temporary animals, apparently quite distinct, are now and then fused together by the discovery of extinct intermediate forms. In Cuvier’s time, horse, tapir, pig, and rhinoceros were ranked as a distinct order from cow, sheep, deer, buffalo, and camel. But so many transitional forms have been found in tertiary strata that pachyderms and ruminants are now united in a single order. By numerous connecting links the pig is now seen to be closely united with the camel and the antelope. Similar results relating to the proboscidians, the hyzena family of carnivora, the apes, the horse, and the rhinoceros, have been obtained from the exploration of a single locality near Mount Pentelikos in Greece.

Gaudry, became a convert to Mr. Darwin’s theory in the course of the search. Referring for many more such examples to the last edition of Sir Charles Lyell’s “Principles of Geology,” let me further observe that there has as yet been but little search for fossils save in Europe and North America, and even these areas have by no means been thoroughly explored. Concerning South America much less is known, and the greater portions of Asia, Africa, and Australia are just so much ¢erra incognita to the paleon- tologist. As M. Gaudry observes, a few strokes of the pick- axe at the foot of Mount Pentelikos have revealed to us the closest connecting links between forms which seemed before very widely separated: far closer will such links be drawn when a considerable portion of the earth’s surface shall have been thoroughly investigated. _ The argument from “missing links,” therefore, in so far as it has any validity at all, is an argument which rests en- tirely upon negative evidence. But negative evidence, as everyone knows, is a very unsafe basis for argument.22 A 1 We may also profitably consider the toxodon, found by Mr. Darwin in South America, which is ‘‘ one of the strangest animals ever discovered. In size it equalled an elephant or megatherium, but the structure of its teeth, as Mr. Owen states, proves indisputably that it was intimately related to the Gnawers, the order which at the present day includes most of the smallest uadrupeds : in many details it is allied to the pachydermata : judging from the position of its eyes, ears, and nostrils, it was probably aquatic, like the dugong and manatee, to which it is also allied. How wonderfully,” says Mr. Darwin, “are vue different orders, at the present time so well separated, blended together in different pvints of the structure of the toxodon !”— Darwin, Voyage of the Beagle, p. 82. Compare the remarks on the quaternary fauna of Western Europe in Sir John Lubbock’s Prehistoric Times, 2nd edition, pp. 296-298. 2 “For instance, the several species of the chthamaline (a weston: or sessile cirrhipeds) coat the rocks all over the world in infinite numbers: they are all strictly littoral, with the exception of a single Mediterranean spevics, which inhabits deep water, and this has been found fossil in Sicily, whereas not one other species has hitherto been found in any tertiary formation : yet it is known that the genus chthamalus existed during the Chalk period.” — Darwin, Origin of Species, 6th edit., p. 271. 42 COSMIC PHILOSOPHY. [pr. 11 single item of positive evidence will always cutweigh any amount of negative evidence. A single case in which two or three species or genera are demonstrably connected with each other through lineally intermediate forms, is enough to outweigh the case of a thousand species or genera in which no such linear connection has yet been demonstrated. Now there can be no question that Hquus, Hipparion, and Anchitherium, are quite distinct genera; and a comparison of the skeletons of the three leaves it equally unquestion- able that the hipparion is simply a more ancient horse, and that the anchitherium is simply a more ancient hipparion. As Prof. Huxley observes, “the process by which Anchitherium has been converted into Hguus is one of specialization, or of more and more complete deviation from what might be called the average form of an ungulate mammal. In the horses, the reduction of some parts of the limbs, together with the special modification of these which are left, is carried to a greater extent than in any other hoofed mam- mals. The reduction is less and the specialization is less in the hipparion, and still less in the anchitherium; but yet, as compared with other mammals, the reduction and specialization of parts in the anchitherium remain great.” ? But as we go back still farther into the Eocene epoch, we find Plagiolophus, a genus intermediate between the horse and the agouti, in which the reduction and specialization of parts is still less. Here, where the exploration has been relatively complete, the intermediate forms are so numerous as to leave no doubt whatever as to the genetic kinship.2 And similarly of the rhinocerotide and hyznide 1 Critiques and Addresses, p. 195. 2 I may add that, in particular, numerous extinct forms intercalary between man and ape are likely to be discovered when we search for them in those parts of the earth where they are likely to exist,—namely, in Africa, Mada- ascar, South-eastern Asia, and the Malay Archipelago. Such formsare not ikely, however, to be directly intermediate between man and the gorilla or the chimpanzee. For these are probably aberrant types, and the connection between man and the authropoid apes is to be sought much lower down,— cH. X1.] TWO OBJECTIONS CONSIDERED. 43 Prof. Huxley says, “it is indeed a conceivable (?) suppo- sition that every species of rhinoceros and every species of hyzena, in the long succession of forms between the Mio- cene and the present species, was separately constructed out of dust, or out of nothing, by supernatural power; but until I receive distinct evidence of the fact, I refuse to run vhe risk of insulting any sane man by supposing that he seri- ously holds such a notion.” lt thus appears that the argument from “ missing links,” which to the general reader may appear so obviously fatal to the Darwinian theory, is to the student of paleontology by no means alarming. Our brief survey of the facts in the case has shown us /irst, that transitional varieties are always likely to have been less numerous in individuals than the well-defined species which they serve to connect ; secondly, that the geologic eras which have left in the rocks the record of their organic life have been usually the eras in which variation and extinction have been least rapid, and in which accordingly transitional varieties have been least numerous; and thirdly, that in spite of all these adverse circumstances, ‘ransitional forms have already been discovered in consider- able numbers, while it is fair to expect that many more will be discovered when by and by we have come to know the earth’s surface more intimately. Of all the objections which have been urged against the theory of natural selection, this objection, from the paucity of transitional forms, is the least weighty, though probably the most obvious. The second objection which we have to ecnsider, though less immediately obvious, is more weighty ; and though there is no reason for regarding it as insuper- able, we must admit that it has not yet been entirely dis- posed of. This objection is implicated with the difference perhaps near the point of eaparhate of the anthropoid apes from the lower monkeys and lemurs. See the anatomical evidence very well presented in Mr. Mivart’s recent work on Man and Apes, 44 COSMIC PHILOSOPHY. [pr. 11, oetween the morphological and the physiological definitions of species, and is usually known as the argument from the infertility of hybrids. As ordinarily stated, indeed, this argument is merely the expression of a sorry confusion of ideas. By a curious misunderstanding the infertility of the mule is often urged as a direct objection to the Darwinian theory. But this is putting the cart before the horse. It is not the infertility of the offspring of the horse and the ass which should be cited as an obstacle to the theory of natural selection, but it is the fertility of the offspring of the carrier- — pigeon and the pouter, or of the pouter and tumbler. Mor- phologically the carrier, the pouter, and the tumbler may well be regarded as distinct species artificially developed from a common wild stock; but so long as mutual infer- tility is held to be the physiological test by which we are to distinguish between varieties and species, it may be argued that, in spite of their great morphological differences, the carrier and the tumbler are only varieties and not true species. And going a step farther, it may be argued that until the theory of natural selection has accounted for the rise of infertility between races descended from a common stock, it has not completely performed the task of reconciling deduction with observation. Against the derivation theory in general, this objection has no weight whatever. That races originally fertile together should, vadedt long subjection to different sets of slincircintuodib become infertile with one another, is @ priori in the highest degree probable, when we reflect upon the extreme sensi- tiveness of the reproductive system to changes of habit in the organism as a whole. When we remember that “the eoiistitubion of many wild animals is so altered by confine- ment that they will not breed even with their own females,” we need not be surprised that the leopard and the lion, which during many ages have had very different habits of life, will not breed with each other, Nor need we wonder ex, X1.] TWO OBJECTIONS CONSIDERED. 45 that the horse and the ass, with less important differences in general habit, have become partially infertile together, to such an extent that their offspring are hopelessly barren. Though the modus operandi of this change is as yet ill- understood, it is nevertheless a change quite in harmony with what we know concerning the intimate dependence of the reproductive system upon the rest of the organism. And let us not fail to note that it is the achievement of this change in the capacities of the reproductive system which completes the demarcation between two bifurcating species, and finally prevents the indefinite multiplication of inter- mediate varieties. But while this objection has no weight as against the theory of derivation in general, it may fairly be urged that the failure to explain the origination of mutual infertility is, for the present at least, a shortcoming on the part of the theory of natural selection. After the conclusive arguments brought up in-our ninth chapter, the derivation theory will no longer, in the present work, be regarded as on trial: that the higher forms of life are derived from lower forms, will be taken as proved. But whether the theory of natural selection has completely fulfilled its proposed task of ex- plaining the mode in which such derivation has been brought about, is quite another question. And while admitting the ‘ull force of the considerations alleged by Mr. Darwin, in his admirable chapter on Hybridism, it seems to me that there is a gap at this point which further research will be required to fill.t As Prof. Huxley reminds us, “it must not be for- 1 I doubt if the hypothesis of natural selection, taken alone, will afford the solution of this problem. It seems more likely that such considerations will have to enter as are presented in Mr. Spencer's Principles of Biology, vol. i. pp. 209-291. Concerning what may be called the ‘‘ dynamics of heredity,” we know as yet but little; but as far as speculation has already gone, Mr. Darwin’s theory of pangenesis seems to me decidedly inferior to Mr. Spencer’s theory of physiological units. J do not discuss these theories here, Seantine it is not necessary for the general purposes of this work It may do no narm, however, to remind some of my readers that “‘ pangenesis” is merely 46 COSMIC PHILOSOPHY. [pr. 11. gotten that the really important fact, so far as the inquiry into the origin of species goes, is that there are such things in nature as groups of animals and of plants, whose members are incapable of fertile union with those of other groups; and that there are such things as hybrids, which are absolutely sterile when crossed with other hybrids. For if such phenomena as these were exhibited by only two of those assemblages of living objects, to which the name of species . 1s given, it would have to be accounted for by any theory of the origin of species, and every theory which could not account for it would be, so far, imperfect.” } We have now reached a point at which we may pause for a moment to contemplate the theory of natural selection in its logical aspect, and to mark its character as a scientific hypothesis. A moment’s inspection will reveal the absurdity of the thoughtless remark—sometimes heard from theologians and penny-a-liners—that the Darwinian theory rests upon purely gratuitous assumptions and can never be submitted to verification. On the contrary, the theory of natural selection, when analyzed, will be found to consist of eleven propositions, of which nine are demonstrated truths, the tenth is a corollary from its nine predecessors, and the eleventh is a perfectly legi- timate postulate. Let us enumerate these propositions :— 1. More organisms perish than survive; 2. No two individuals are exactly alike; 3. Individual peculiarities are transmissible to offspring 3 4, Individuals whose peculiarities bring them into closest adaptation with their environment, are those which survive and transmit their peculiar organizations ; 5. The survival of the fittest thus tends to maintain an equilibrium between organisms and their environments ; a subsidiary hypothesis, with the possible inadequacy of which Mr, Darwin’s main theory is in no way concerned, 4 Huxley, Lay Sermons, p. 393, cH, XI.] TWO OBJECTIONS CONSIDERED. 47 6. But the environment of every group of organisms is steadily, though slowly, changing ; 7. Every group of organisms must accordingly change in average character, under penalty of extinction ; 8. Changes due to individual variation are complicated by the law that a change set up in any one part of a highly complex and coherent aggregate, like an organism, initiates changes in other parts; 9. They are further complicated by the law that structures are nourished in proportion to their use ; 10. From the foregoing nine propositions, each one of which is indisputably true, it is an inevitable corollary that changes thus set up and complicated must eventually alter the specific character of any given group of organisms ; 11. It is postulated that, since the first appearance of life upon the earth’s surface, sufficient time has elapsed to have enabled such causes as the foregoing to produce all the specific heterogeneity now witnessed. It seems to me that this summary fairly represents the logical character of the theory of natural selection. The theory is so strong that no scientific writer is disposed to deny that the process of natural selection has always gone on and must continue to goon. And the inference cannot be avoided that in due course of time the process must work specific variations. The only purely hypothetical portion of the theory is the assumption that past geologic time has been long enough to allow of the total process of evolution by such infinitesimal increments. But concerning this assump- tion, 1t is the clear verdict of logic, that if the theory is thoroughly substantiated in all its other portions, we have the right to claim as much time as is needful, provided we do not run counter to conclusions legitimately reached by astronomy, geology, or physics. Now concerning the age of the earth, neither astronomy, nor geology, nor physics, has as yet had anything conclusive to say; and it must be left for 48 COSMIC PHILOSOPHY. [pr. 11. future inquiries to give us the quantitative data requisite for settling this point.1_ We cannot yet, indeed, estimate the age of the last great glacial epoch with any approach to accuracy; yet the age which we assign to this epoch must enter as an important factor into our estimates of the antiquity of pre- ceding epochs. But while this point remains undetermined, it may be noted that even the decision which leaves the smallest time for the operation of unaided natural selection can weaken the Darwinian theory only on the assumption that the agency already alleged by that theory has been the sole factor concerned in forwarding organic evolution; and this assumption, though it may have been made by over- confident disciples of Mr. Darwin, has never been made by Mr. Darwin himself. Mr. Darwin is too profoundly scientific in spirit to imagine that, with all his unrivalled patience and sagacity, he has completely solved one of the most intricate problems with which the student of nature has ever been called upon to deal. It is more than likely that future research will disclose other agencies which have cooperated with natural selection in accelerating the diversification of species. Meanwhile the evidence in behalf of the first ten propositions involved in the Darwinian theory is sufficiently strong to make it apparent that a vast amount of specific change must have taken place, and also that natural selection has been a chief factor in producing that change. To the urguments which in our ninth chapter were seen to overthrow the dogma of fixity of species, may now be added the argument that at least one group of clearly-defined agencies is at work, with which, in the long run, the fixity of species must become incompatible. The explanation of the details of specific differentiation may well form the subject of cautious investigation for many generations of observers and 1 The reader who wishes to see how fallacious all pang at reachmng the age of the earth from astronomico-physical arguments are likely to prove with our present resources, may consult Huxley’s Lay Sermons, pp. 268 279. thinkers. But enough has already been explained to draw forth the undeniable Fact of Derivation from the region of - mystery in which it was formerly half-hidden, and thus to place the Theory of Derivation upon a thoroughly scientific basis. In expounding the way in which this has been done, we have obtained several useful conceptions, which will uot - fail to do us good service in future chapters. CHAPTER XIL ADJUSTMENT, DIRECT AND INDIRECT. ' AN objection much less obvious than the two considered in the foregoing chapter, is brought up by Mr. Mivart against the theory of natural selection. In the Cuvierian classifica- tion, the marsupials were ranked as an order of mammalia, side by side with orders like the carnivora or rodentia. This arrangement is now obsolete. The class of mammals is no longer directly divided into orders, but is first separated into three sub-classes, the monodelphia, didelphia, and ornitho- delphia. The latter sub-class, forming the link between mammals and sauroids, is now nearly extinct, being repre- sented only by a single order, containing two genera, the Australian echidna and duck-bill. Leaving these aside, all other mammals, except the marsupials, are comprised within the sub-class monodelphia. The didelphia or marsupials are divided by Prof. Haeckel into eight orders; and between these orders and sundry orders of the higher monodelphia there is a curious parallelism. For example there is an order of edentate marsupials, there is a marsupial order of carnivora, and another of insectivora, and another of rodents, while the kangaroo strongly resembles the sub-order of ruminants, and the opossum is clearly related to the lemurs, or lowest of the primates It becomes, “hen, an interesting problem to settle ae ee ee ee ow ere, eee em i cu. x11.] ADJUSTMENT, DIRECT AND INDIRECT, 51 the genetic relationships between the two sub-classes. Did the order of apes descend from the ape-like marsupials, the monodelphian carnivora from the didelphian carnivora, the higher rodents from the marsupial rodents, and so on? If so, it is difficult to see how the pouch should have been lost, and the placenta developed in so many different orders independently: such a number of exact coincidences seem hardly probable. On the other hand, did all the monodelphia descend from one didelphian form? If so, it is strange that the differentiation into orders should have gone on so similarly in the two sub-classes, resulting, for example, in the production of marsupial mice which in general appearance are hardly distinguishable from placental mice. Birds and reptiles present an equally puzzling cross- relation. Upon no theory are these the direct ancestors of mammals, although the lowest mammals are both bird-like and reptilian in appearance. The duck-bill, belonging to the mammalian sub-class of ornithodelphia, somewhat resembles a lizard with a bird’s beak. Embryology shows that the three classes are divergent offshoots from an amphibious or batrachioid ancestor; but the birds and reptiles resemble each other much more closely than either resembles the mammalia, so that Prof. Huxley joins them together in the super-class or province of sauroids. So far all is plain; but when we inquire by what forms the birds and reptiles are linked most closely together, we are met by a difficulty. Birds:are divided into two sub-classes: the ostrich, cassowary, emeu, dinornis, etc., are grouped together as struthious birds, while all other existing forms belong to the sub-class of carinate birds. Now until quite lately it was supposed that li birds were descended from an extinct reptilian form like “kat ancient reptile, the flying pterodactyl. For the resem- tlances in structure between the pterodactyls and the carinate birds are striking enough to have suggested an immediate com- munity of origin, Nevertheless, within the past seven years, E 2 52 COSMIC PHILOSUPHY, [Pr. 11 a much stronger case has been made out in favour of the descent of the struthious birds from large reptilian forms akin to the dinosauria,—of which extinct order the member most commonly known is the gigantic iguanodon. Now here, says Mr. Mivart, is a dilemma just like the one which confronted us in the case of mammals. If all birds started from the pterodactyl, why do the struthious birds so strongly resemble a totally different reptile? If all birds started from a dinosaurus, why do the carinate birds so strongly resemble the pterodactyl? If we try to split the difference, and say that the carinate birds started from the pterodactyl, while the struthious birds started from the dinosaurus, the difficulty is immensely increased. For then the question arises, how could the struthious and the carinate birds, starting from such different points, have come to resemble each other so strongly ? _ Mr. Mivart is careful to state that these zoological cross- relations do not constitute an obstacle to the theory of evolu- tion. They are difficulties only on the theory that organic evolution has been solely caused by the natural selection of fortuitous variations. To make this more clear, let us pro- visionally accept one of each of the pairs of alternatives offered by the two cases just described. Let us agree, with Prof. Haeckel, that all the monodelphian mammals have come from one didelphian; and let us agree, with Prof, Huxley, that the kinship between birds and reptiles is closest in the case of the struthious birds and the dinosattrians, Now we are obliged to maintain that the original monodel- phian branched off into a dozen or more forms, of which six or seven happen to agree remarkably, in general appearance and in habits of life, with six or seven of the forms into which the original didelphian had at an earlier date branched off. And we are also obliged to maintain that the remark- able shoulder-structure of the pterodactyl, in which it agrees so closely with the carinate birds, was independently evulved Se eee NOTRE Se ese By S Tn ena en. xu.) ADJUSTMENT, DIRECT AND INDIRECT, 53 and has a purely physiological significance. That is to say, the resemblance of the pterodactyl to carinate birds is a secondary adaptive resemblance, like the less marked re- semblance of bats to birds, or like the resemblance of a porpoise to a fish. And this view, which seems to be Prof. Huxley’s, is rendered probable by the fact that in wing- structure the pterodactyl differs from birds in much the same way that a bat does. We are now extricated from our imbroglio with regard to classification, but we are still left confronted with the diffi- culty of supposing that the natural selection of casual varia- tions can so often have resulted in producing whole orders of closely-resembling animals from distinct ancestral orders. Other facts, brought up by Mr. Mivart, still further increase the apparent difficulty. The most important of all these relate to the development of the higher organs of sense in the three sub-kingdoms of annulosa, mollusks, and vertebrates. Coincidences between the members of any one of these sub-kingdoms and the members of the others, are not to be attributed to community of origin. No naturalist supposes that an annulose animal, or a true mollusk, has ever been developed into a vertebrate. And while the mol- lusks and vertebrates appear to have diverged from a mol- luscoid ancestor akin to the still-living ascidians, the annulose sub-kingdom has a totally different pedigree. To discover any likeness between the two great groups, we must follow them back to those remotest ancestors who possessed hardly any distinctively animal characteristics. Bearing all this in mind, it is a striking fact that the eye of the cuttle- fish, which is the highest of mollusks, appears te be con- structed like the eyes of vertebrates. It apparently contains not only a similar retina, but also a lens, the choroid and sclerotic tunics, and the vitreous and aqueous humours. Now this coincidence cannot be due to community of in- beritance, for the vertebrate and molluscous sub-kingdoms 54 _ OOSMIC PHILOSOPHY, [pr. 1 are linked together only at their lowest extremities, and while the lowest vertebrate has an eye far inferior to the one just described, the molluscoid ascidians have merely rudimentary eye-spots. The coincident structures have there- fore been independently developed. Again, Mr. Mivart urges that the agreement cannot be explained on the assumption “that the conditions requisite for effecting vision are so rigid that similar results in all cases must be independently arrived at”; for the eyes of the higher insects, which are excellent visual organs, differ very widely in structure from those of the cuttle-fish and the higher vertebrates. Here, therefore, is a difficulty ; and it is still further increased if the alleged fact be true, that there is a similarly close correspondence between the auditory structures in the vertebrates and in the cuttle-fish. In presenting these difficulties I have closely followed Mr. Mivart, whose scientific arguments are usually stated with a clearness and precision which one would gladly see paralleled in the philosophic discussions by which they are supplemented, I have selected these arguments because they seem to me to constitute the strongest portion of the case which Mr. Mivart has brought to bear against the theory of natural selection; and also because by seeing whither they tend, we shall begin to see how the theory of natural selection must be supple- mented, before it can become a complete explanation of the phenomena with which it deals. Now we must at the outset admit that natural selection must act upon every individual variation which is distinctly auvantageous or injurious to the species,—always preserving } the former and rejecting the latter. This process must equally go on, whether the variation is a mere idiosyncrasy, such as we call fortuitous, or whether it is one that is manifested simultaneously by a large number of individuals, so that it may be traced to causes acting upon them all in common. Now this latter case is the one which must here be taken into the account. If a large number of individuals may simul- on. x11.) ADJUSTMENT, DIRECT AND INDIRECT, 54 taneously vary in a given direction, and if this may often happen within the limits of single generations, it is obvious that: we have here a factor of specific change not to be lightly passed over. In estimating the effects of natural selection upon a number of variations which are, quite legitimately, taken for granted, we must not forget to generalize the varia- tions in connection with some common cause to which they may be assignable. Now it cannot be denied that in any single generation of organisms variations are very likels to occur, throughout nearly the whole number of individuals, which are due to the direct adaptation of the species to its environing circumstances. When exhibited in the effects wrought upon the human constitution by exposure to changed physical conditions, such variations are known as acclimatiza- tion. Within the infinitesimal period of two centuries the English race in America has come to differ perceptibly, though : very slightly, from the English race in Europe; and this very slight difference, which cannot be explained by the much overrated hypothesis of the infusion of foreign blood, and which certainly cannot be traced to natural selection, must be almost wholly due to direct adaptation to new physical and social conditions. Of kindred import is the fact that “twenty-nine kinds of American trees all differ from their nearest European allies in a similar manner, having leaves less toothed, buds and seeds smaller, fewer branchlets, etc.” So M. Costa states “that young shells taken from the shores ot England and placed in the Mediterranean at once altered their manner of growth, and formed prominent diverging rays like those on the shells of the proper Mediterranean oyster.” We have seen that the direct action of physical agencies will by no means account for the chief features of colouring in the organic world ; yet it appears to be true that members of the same species of birds are more brightly coloured when living in a clear dry atmosphere than when living near the coast. So, ton, in the contour of their wings, the various 6 COSMIC PHILOSOPHY. (Pr. an butterflies of Celebes all show parallel divergences, inexpli- cable by natural selection alone, from kindred species in Java and India. And a host of like facts concerning these insects are cited by Mr. Mivart from Mr. Wallace’s essay on the Malayan Papilionide. More examples might be cited if this work were intended to be a scientific treatise on Darwinism ; but for the comprehension of the present point, in its philo- sophic bearings, these illustrations will suffice. Facts of this kind point to the conclusion that an inherent capacity for adaptive changes is possessed by all organisms. And by the phrase “inherent capacity” I do not mean to insinuate the existence of any occulta vis, or metaphysical “innate power,” of which no scientific account is to be given in terms of matter and motion. An organism is a complex system of forces; even the simplest living patch of proto- plasm is a highly complex system, but in the higher organisms the complication of forces is almost infinite, when compared with our limited powers of analysis. Now such a system of forces must, under penalty of overthrow, maintain both its internal equilibrium and its equilibrium with external inei- dent forces. And this double maintenance of equilibrium necessitates a rhythmical redistribution of forces from mo- ment to moment, of which, as was shown in the chapter on rhythm, the result must be continual change. Now the internal equilibration of the forces in the organism with each other, is generalized in the laws of growth, development, and heredity ; while the external equilibration of the forces in the organism with environing forces, is generalized in the Jaws of variation and adaptation. As the result of the former process, all organisms tend to assume certain typical forms, as inevitably as crystals. In the case of the lowest organisms the forms assumed may possibly be due to the operation of chemical polarity similar (though much more involved) to that which gives form to crystals. In all but the lowest organisms the forms assumed are the expression of tendencies AIR ee IS 2 SDE STA Se See ape a aol ae a on, x1u.] ADJUSTMENT, DIRECT AND INDIRECT. 57 due to the cooperation of countless ancestral forces; and such tendencies are now not improperly classified under the head of “ physiological polarity,’—provided that nothing more is meant by “polarity” than the ability of certain special groups of forces to work different structural changes in different directions. So much for the internal adaptive process. But now, as the result of the parallel process of external adaptation, it follows that the forms due to the internal process can remain constant only so long as the environment remains unchanged. If the changes in the environment are too great or too sudden to be equilibrated by changes in the distribution of the system of internal forces, the system is overthrown, and the organism perishes. But if the external changes are moderate and yradual, the adjustment of the organism to them by means of internal changes, must result in that kind of organic variation known as direct adaptation. We need not be surprised, therefore, by the parallel variations of whole genera of American trees or Malayan butterflies; nor need we ascribe them, with cer- tain recent writers, to “occult energies” of the metaphysical sort, or to a kind of pantheistic “intelligence ” inherent in nature, or to any other agency unrecognizable by science ; since the necessity for such parallel variations, wherever whole groups of organisms are exposed to like environing agencies, is a corollary from the fundamental principles of vital dynamics. , We are now in a position to amend quite materially the view thus far taken of the causes of organic evolution. Hitherto we have concerned ourselves too exclusively with the selection of variations, omitting to inquire into the cha- racter and mode of origin of the variations selected, But the latter point is no less important than the former. If variations might occur equally in all directions from the average standard, by reason of circumstances so indefinitely compounded as to’ make them seem fortuitous, then the be COSMIC PHILOSOPHY. [pr 1 natural selection of such variations might well be pronounced incapable—save in very rare instances—of working entirely analogous results in organisms so genetically distinct as monoc2!phians and didelphians, or as vertebrates and mol- lusks. In other words, natural selection, acting upon such fortuitous individual variations, would tend to produce in- definitely increasing differentiations in many directions, Such differentiations are to be seen in the amazingly elabo- rate contrivances for the fertilization of orchids, the expla- nation of which is one of Mr. Darwin’s most brilliant achievements. But when it is admitted that a great num- ber of similar adaptive variations must be simultaneously occurring in the same direction, then it is obvious that the natural selection of such variations may often produce ana- logous results in different genera and families, or even in different orders, classes, or sub-king¢doms. Mr, Mivart alleges the many resemblances between whales and the ancient ichthyosaurians, as hardly explicable on the theory of the selection of fortuitous variations. But when we recol- lect that the vertebrate structure of mammals is at the out- set homologous with that of reptiles, and that direct adaptation must of itself tend to produce similar variations alike in mammals and in reptiles which pass from a terrestrial into an aquatic environment, the resemblance between a whale and an ichthyosaurus ceases to be an enigma. The superficial resemblance of a whale to a fish is a fact of like nature. And in the case of amphibious carnivora, like the seal, direct adaptation to a partially marine environment has aided in producing fish-like limbs, while it has not interfered with the general likeness of the animal to certain families of land carnivora. So in the case of the pterodactyl as compared with carinate birds, we begin with skeletons constructed on the same plan, and we may expect to find that direct adapta- tion to the necessities of flight will tend to produce similar modifications of the shoulder-structure. But since, before web OS Ie PAS ee See ae eR ie nd . —" 3 “3 eu. xu.) ADJUSTMENT, DIRECT AND INDIRECT. 59 the appearance of pterodactyls, the dermal covering of reptiles was very likely as different from that of birds as it is now, so that a reptilian wing could not be formed by a modification of the dermal covering, we find, naturally enough, the wing of the pterodactyl formed, like that of the bat, by a modification of the skeleton. And this fact seems to justify us in the alternative which we have accepted, that the likeness of the pterodactyl to birds is no proof of im- mediate kinship, but only of secondary adaptive variaticn, as in the case of bats. A similar argument applies to the numerous likenesses between the higher mammals and the marsupials, At an ancient epoch the marsupials were a dominant race of animals, extending all over the world. But since they have been almost everywhere exterminated by their hardier monodelphian descendants, there is no difficulty in the view that direct adaptation to similar differ- ences of environment, when aided by natural selection, has brought about a differentiation of the higher mammals analo- gous to that which had formerly taken place among the marsupials. That six or seven orders of monodelphians should vary in the same direction with six or seven orders of didelphians, is no more surprising than that twenty-nine kinds of American trees should all differ in the same direc- tion from their European congeners, It is certainly far less surprising than would be the simultaneous loss of a pouch and acquirement of a placenta by a host of marsupial genera scattered all over the earth. Pursuing the argument a step farther, we may begin to understand, in a general way, even the similarity of the eye of a cuttle-fish to the eye of a vertebrate. Utterly unlike a vertebrate in general structure, and so remotely akin that - for practical purposes of argument the kinship is of no account,—if a cuttle-fish could be shown to possess numerous points of special resemblance to a vertebrate, the fact would be an obstacle to any theory of the origin of organic forms, 60 COSMIC PHILOSOPHY. [pr. 1. But the only special resemblances which are found to exist, are those between the eyes and the ears. Now these are organs in which such variations as occur must be in a pre- eminent degree directly adaptive. The eye, for example, contains an optical apparatus of which the function is the concentration of rays of light into a focus upon the retina. Such is the function discharged by the lens, and the vitreous and aqueous humours. Now, while the compound eyes of insects show us that this function can be discharged in more than one way, a brief consideration of the optical conditions | in the case would show that it can only be accomplished in a few ways. Not only does the passage of the light directly tend to set up molecular rearrangements in the refracting matter which lies before the retina, but out of those rearrange- ments there are very few which can assist the focalizing pro- cess, so that natural selection, in preserving the best-refracting eyes, would have but very few directions in which to act. The anterior membrane might differentiate into a number of converging lenses, as in the higher annulosa, but if such a differentiation did not occur, it is difficult to see how the needful refraction could be secured, save by the differentiation of the successive strata which we call the aqueous, crystalline, and vitreous humours, This may serve to indicate the course of explanation to be taken. The physical conditions for securing very efficient vision being thus limited, and direct adaptation being such an important factor in the process, it does not seem at all strange that two eyes quite similar in structure should be independently produced. A precisely similar argument will apply to the case of the ear. And the force of these considerations is still further increased when we learn from Prof. Gegenbaur that the resemblances be- tween the eyes of vertebrates and the eyes of cuttle-fishes are only superficial analogies, and not fundamental homologies, as Mr. Mivart’s very exaggerated statement might lead one to suppose. ge PT ee eee ea ex. xu.] ADJUSTMENT, DIRECT AND INDIRECT. 61 In all these cases, here too briefly summed up, natural selection must of course be regarded as steadily cooperating with direct adaptation. No matter whether individual vari- ations are directly called forth by environing agencies, or are due to internal causes, in our ignorance of which we call them fortuitous, they must equally be the objects of natural selection wherever they influence, in the slightest degree, the individual’s chances of survival. Thus the theory of natural selection is not superseded, but supplemented, by the class of considerations here suggested by Mr. Mivart’s objections. Ordinarily, if not always, the two processes must go on in concert; and while the frequent occurrence of directly adap- tive changes must greatly accelerate the operation of natural selection, on the other hand natural selection, by weeding out all cases of retrograde variation, must complete the work of direct adaptation. There are, however, some conspicuous instances in which natural selection seems to play either a very subordinate part, or none at all, As we have just been considering eyes and ears, let us once more return to them, to show how certain peculiarities in their structure must be chiefly due to directly adaptive changes. Within the human ear, firmly fastened in the temporal bone, is a spirally-coiled chamber, known as he cochlea. Within this chamber there is a very elastic membrane, and on it lie the so-called fibres of Corti, which are a series of fibrous filaments placed side by side, with great regularity, so as to present somewhat the appearance of the key-board on a piano. It is now held by physiologists that this row of fibres is really a key-board, and that each fibre is set in vibration only by a particular musical note, exactly as an A-tuning-fork is set vibrating when A is sounded near it, but not when any other note is sounded. The auditory nerve, in passing into the cochlea, branches into an immense number of nerve-filaments, each of which com- inunicates with one of the keys of this ear piano. So that 62 COSMIC PHILOSOPHY, | (pr. 1, when A is sounded on a musical instrument, the A-key within the ear vibrates, and transmits its vibrations to a special filament of the auditory nerve. If this view be correct, we have here a truly marvellous instance of dif- ferentiation. But now in what way can this structure have ever been useful to human beings in the struggle for life ? Doubtless a considerable power of discriminating sounds is useful to any animal, but of what use can it be to distinguish between A and A-sharp? We may safely conclude, I think, that survival of the fittest has played quite a secondary part in this case. The explanation must be sought in the direct effects wrought by auditory vibrations upon the molecular structure of the cochlear fibres. And it is a system of effects which has not even yet been wrought in its present complete- ness save among highly civilized people, A savage cannot distinguish the slight variations in pitch by which our ears are delighted. And even among ourselves there are ears which can neither in melody discriminate between the ascending and the descending gamut, nor in harmony distinguish between the mellifluous tonic chord and the harsh inversions of the minor ninth. The defect may be compared to that of colour-blindness, although it is probably more common because the ear has been far less thoroughly trained than the eye. Now when we consider how much can be effected by individual training in enabling a moderately good ear to discriminate between quarters, eighths, and smaller fractions of a tone, and bear in mind that this training must consist in the further differentiation of the sensitive cochlear fibres, we have a strong argument in favour of the production of this wonderful structure by direct adaptation alone. | Concerning the human eye I need only say that in the retina it presents a structure closely analogous to the ear- piano just described. The chief layer of the retina is com- posed of little rods of nerve-tissue, packed closely together en, x11.) ADJUSTMENT, DIRECT AND INDIRECT, 63 like organ-pipes ; and it is probable that each of these rods vibrates in unison with a particular ray of light. Here is a case of extreme differentiation just like that witnessed in the ear; and substantially the same argument will apply to it. The survival of a primeval savage in the struggle for life would certainly depend to a considerable extent on his ability to discriminate certain colours as well as outlines by the eye, as also upon his ability to recognize the timbre or quality of certain sounds. But the power of distinguishing the delicate shades in a painting of Correggio could be no more useful, from a zoological point of view, than the power of appreciating the most subtle harmonic effects in a symphony of Schumann. For this extreme differentiation there would seem to be no assignable cause save the direct action of luminous waves upon the wonderfully sensitive and responsive nerve-tissue of civilized man. Were it needful for the further illustration of our position, I might show how Mr. Spencer has proved that the structure of vertebral columns is also primarily due to directly adaptive changes. Many peculiarities in the shapes of plants and animals are probably thus to be explained. And in regard to the hues of organisms—those phenomena which are so beautifully explained by the Darwinian theory—there are some exceptions to be cited. The magnificent tints of many corals, of certain caterpillars, and of the shells of sundry muilusks, must undoubtedly be due to the direct working of such chemical affinities as produce our wonderful aniline dyes, or the rich tints of our American autumn woods. But passing over all these interesting points, enough has been said to show that there are many phenomena vu: organic evolution which natural selection, when ‘considered alone, will not suffice to account for, But, with the amendments 1 This is the opinion of Helmholtz, the greatest living authority ; and it is strengthened by Dr. Brown Séquard’s discovery of the number of fibres in the spival cord which are specialized for the reception of particular sersations. 64 COSMIC PHILOSOPHY. [pr. IL now agreed upon, there may be framed an outline of a tolerably complete classification of agencies. Let us reduce to a common form of expression the agencies contemplated in this and in the two preceding chapters. Considered in the widest sense, the processes which we have seen to cooperate in the evolution of organisms are all processes of equilibration or adjustment. From the dyna- mical point of view, as bas been shown in previous chapters, an organism is a complex aggregate of matter, in which per- manent structural and functional differentiations and inte- grations are rendered possible by the fact that it continually receives about as much motion as it expends. Now a state in which expended motion is continually supplied from without, is called a state of dependent moving equilibrium. In other words, it is a state in which every change in the distribution of external forces must be met by a change in the distribution of internal forces, in order that the equili- brium may be preserved. This is the case with every organism. Its life is a perpetual balancing of external forces by internal forces. And the complete accomplishment of this end requires also that there shall be a continuous internal equilibration,—a perpetual balancing of forces opera- tive in the different parts of the organism. Thus the career of an organism, or of a group of organisms, consists of two kinds of equilibration, which we may briefly designate as external and internal equilibration. And a moment’s con- sideration will show us that each of these kinds of equilibra- tion may be either direct or indirect. The adjustment of a eroup of organisms to changing external circumstances is effected partly by such direct adaptations as we have above considered, partly by the destruction of all those members of the group which do not become directly adapted. In this latter way equilibrium is maintained indirectly ; and natural selection, or survival of the fittest, may be accurately cha- racterized as “indirect equilibration.” Turning now to the cn. x1.] ADJUSTMENT, DIRECT AND INDIRECT. 65 internal processes, we see that direct equilibration which consists in continually arranging all the units of the organism in accordance with their physiological polarities, exemplified alike in heredity and in correlation of growth. On the other hand the dwindling and final evanescence of organs which are disused, is due to the fact that the nutritive material is all needed by the other organs which are in constant use ; and it may accordingly be regarded as an indirect method of preserving the internal equilibrium of the organism. The process of organic evolution may therefore be summarized as follows: External Direct .« « Adaptation. ee : Indirect . Natural Selection. Equilibration Shier Heredity. Internal * * ( Correlation of Growth. Indirect . Use and Disuse, Here we have a classification of agencies coextensive with uur present knowledge of the subject, and sufficiently com- prehensive to include such factors in the problem as may hereafter be discovered. Under one of these four sub-divi- sions every special process concerned in forwarding organic evolution must be included. For since it is admitted on all sides that specific change is due to the necessity for main- taining equilibrium between the organism and the environ- ment, it follows that every process which results in the modification of species must be a process of adjustment or equilibration, either external or internal, direct or in- direct. In the scientific treatment of the problem, there is room for much beside natural selection, but there is no room for occulice vires, or pantheistic intelligences, or for “ten- ‘encies,” save such as may be expressed as the unneutralized surplus of forces acting in a particular direction. But we have now done something more than merely to classify the causes of organic evolution. In the act of classifying these, we have arrived at the law or formula VOL, II. ¥F 66 COSMIC PHILOSOPHY, [pr. IL which expresses the chief characteristic of organic evolution. We have reached the all-important truth that the progress of life on the globe has been the continuous equilibration of the organism with its environment. We need now only go a step farther in order to obtain a formula which will not only express the distinguishing characteristic of Life itself, but will also serve as an immediate basis for our inquiries into the phenomena of mind and of society, CHAPTER XIIL LIFE AS ADJUSTMENT, OnE of the cardinal propositions of Mr. Spencer’s system of philosophy is the definition of Life, first published in 1855, in his “ Principles of Psychology,” but now transferred to the first volume of his “Principles of Biology.” According to Mr. Spencer, the continuous maintenance of an equilibrium between the organism and its environment is the process in which life essentially consists. Life—including also intel- ligence as the highest known manifestation of life—is the continuous establishment of relations within the organism, in correspondence with relations existing or arising in the environment.! Out of the host of illustrations by which 1 The full definition runs thus :—‘*‘ Life is the definite combination of heterogeneous changes, both simultaneous and successive, in correspondence with external coexistences and sequences.” This is incomparably the most profound and complete definition of Life that has ever been framed; and the chapter in which it is set forth and illustrated woald alone entitle Mr. Spencer to a place among the greatest thinkers that have ever lived. The objection has indeed been raised, in metaphysical quarters, that this is a definition, not of Life, but of the circumstances or accidents in which Life is manifested. Concerning this objection, we may content ourselves with the following re- marks by Mr. Lewes. Both Life and Mind, says Mr. Lewes, are processes, ** Neither is a substance ; neither is a force. To speak of Vitality as a sub- stance would shock all our ideas; but many speak of it as a force. They might with equal propriety hold Mortality to be a force. What, then, is meant by Vitality, or vital forces? If the abstraction be resolved into its concretes, it will be seen that a certain process, or group of processes, is con- densed into a simple expression, and the final result of this process is trans- F 2 68 COSMIC PHILOSOPHY. (pr. 1 this formula is justified, it will be sufficient for our present purpose to select but one or two. “The stinging and con- tractile powers of a polyp’s tentacle correspond to the sensi- tiveness and strength of the creatures serving it for prey. Unless that external change which brings one of these creatures in contact with the tentacle were quickly followed by those internal changes which result in the coiling and drawing up of the tentacle, the polyp would die of inani- tion. The fundamental processes of integration and dis- integration within it would get out of correspondence with the agencies and processes without it; and the life would cease.” So in higher animals, “every act of locomotion im- plies the expenditure of certain internal mechanical forces, adapted in amounts and directions to balance or out-balance certain external ones. The recognition of an object is impos- sible without a harmony between the changes constituting perception, and particular properties coexisting in the en- vironment. Escape from enemies supposes motions within the organism, rela!«:| in kind and rapidity to motions without it. Destruction of prey requires a particular combination of subjective actions, fitted in degree and succession to overcome a group of objective ones. And so with those countless automatic processes exemplified in works on animal instinct.” And similarly, as will appear still more clearly when we come to treat especially of the evolution of intelligence, “the empirical generalization that guides the farmer in his rotation of crops, serves to bring his actions into concord with certain of the actions going on in plants and soil; and the rational deductions of the educated navigator who calcu- lates his position at sea, constitute a series of mental acts by posed from a resultant into an initial condition, the name given to the whole group of phenomena becomes the personification of the phenomena, and the product is supposed to have been the producer. In lieu of regarding vital actions ag the dynamical results of their statical conditions, the actions are personified, and the personification comes to be regarded as indicating some thing independent of and antecedent to the concrete facts it expresses.”— Protlems of Life and Mind, vol. i. p. 110. ou, X11.) LIFE AS ADJUSTMENT. 69 which his proceedings are conformed to surrounding cireum- stances.” We practically recognize the truth of this definition of life when we attempt to ascertain whether an animal is dead or alive by poking it with a stick. If it responds by motions of its own, we judge it to be alive; if it merely moves as the stick pushes it, we judge it to be dead. So we decide whether a tree is alive or dead by observing whether the increased supply of solar radiance in spring causes those internal motions which result in the putting forth of leaves, In these cases we recognize the truth “that the alteration wrought by some environing agency on an inanimate object does not tend to induce in it a secondary alteration, that anticipates some secondary alteration in the environment, But in every living body there is a tendency towards secondary alterations of this nature; and it is in their pro- duction that the correspondence consists.” This formula for vital phenomena is further illustrated and justified by the fact that the degree of life is low or high, according as the correspondence between internal and external relations is simple or complex, limited or extensive, partial or complete, imperfect or perfect. The lowest forms of life respond only to the simpler and more homogeneous changes which affect their total environment. The relations established within a plant answer only to the presence or absence of a certain quantity of light and heat, and to the chemical and hygrometric relations existing in the envelop- ing atmosphere and subjacent soil. In a polyp, besides general relations similar to these, certain more special rela- tions are established in correspondence with the external existence of mechanical irritants; as when its tentacles contract on being touched, The increase of extension acquired by the correspondences as we ascend the animal scale, may be seen by cantrasting the polyp, which can simply distinguish between soluble and insoluble matters, 70 COSMIC PHILOSOPHY, [pr. 11 or between opacity and translucence in its environment, with the keen-scented bloodhound, and the far-sighted vulture. And the increase of complexity may be appre- ciated by comparing the motions respectively gone through by the polyp on the one hand, and by the dog and vulture on the other, while securing and disposing of their prey. In the next chapter it will be shown that the advance from lower to higher forms of life consists in the orderly establish- ment of relations within the organism, answering to external relations of coexistence and sequence, that are continually more special, more remote in space and in time, and more heterogeneous ; until at last we reach civilized man, whose intelligence responds to every variety of external stimulus, whose ordinary needs are supplied by implements of amazing complexity, and whose mental sequences may be determined by circumstances as remote as the Milky Way and as ancient as the birth of the Solar System. When viewed under this aspect the phenomena of life and of intelligence are so similar that it is difficult to keep them separate in our series of illustrations. As we proceed to treat of psychology, we shall much better appreciate the importance of the truth which I am now expounding. Restricting ourselves here, as far as possible, to physiological illustrations, let us note that in any organism life continues just so long as relations in the environment are balanced by internal relations, and no longer. The difference in result between a jump from a horse-car and a jump from an express train running at full speed, depends simply on the difference in the ability of the contracting muscles to neu- tralize a small or a large quantity of arrested momentum. The motor energy with which the head is carried forward antil it strikes the ground, is exactly the surplus of external - force to which the organism has failed to oppose an internal force. If the resulting concussion of the brain is not. se great av to induce instant death, but only causes inflamma cH. X1I1.] LIFE AS ADJUSTMENT. 71 tion, with temporary loss of consciousness, then the con- tinuance of life will depend upon the ability of the molecular forces within the organism to bring about a redistribution of matter and motion which shall balance the sudden redistri- bution caused by the blow. Dynamical pathology regards all diseases as disturbances of the internal equilibrium of the organism, and recovery is the restoration of the equili- brium. The avoidance of danger is the coordination of certain actions in anticipation of more or less complex relations about to arise without. If disease and danger be successfully avoided, the death which ensues in old age is due to the diminished plasticity of the organism which renders it incapable of responding to external changes. As we saw when treating of the primary aspects of Evolution and Dissolution, the evolution of the body, even to the close of life, is characterized by the integration of its constituent matter, shown in the increasing proportion of solids to fluids which makes the bones brittle, the muscles stiff, and the nerves sluggish. Death from old age ensues just when the consequent molecular immobility has reached the point at which incident forces can no longer be balanced by internal rearrangements. A paragraph will suffice for the exposition of this formula of life in connection with the general law of evolution. That the evolution of life upon the earth, beginning with innumerable jelly-like patches of protoplasm, like the monera discovered by Prof. Haeckel, and ending with more than two million species of plants and animals such as naturalists classify, has been a change from homogeneity to heterogeneity, will be denied by no one. Nor is it needful to repeat, save for form’s sake, what was sufficiently illus- trated in an earlier chapter,—that the higher forms are also those in which the various orders of integration are most completely exemplified. We need only to note that the continuous adjustment of the organism to its environment, 72 COSMIC PHILOSOPHY. [PT. 11 in which process we have seen that life consists, must ne- cessitate both the differentiation of the organism and the integration or definite combination of the changes which constitute its activity. For as the life becomes higher the environment itself increases in heterogeneity as well as in extent. The environment of a fresh-water alga is, as Mr. Spencer remarks, limited to the ditch or pool in which the alga lives. The acaleph borne along on a wave of the sea has a much more homogeneous environment than the cater- pillar which crawls over leaves; and the actions by which the caterpillar must “meet the varying effects of gravita- tion,” are far more heterogeneous than the actions of the acaleph. In the case of the higher animals, not only is their environment extremely heterogeneous as consisting to a great extent of adjacent organisms which stand to them in the relations of enemies, competitors, or prey; but it also presents highly coordinated actions on the part of these organisms, which must be met by highly coordinated actions on the part of the former. Thus with the increase of the organism in heterogeneity, definiteness, and coherence, its environment increases in heterogeneity and presents more definite and coherent relations to which the organism must adjust itself. And in this way the heterogeneous, definite, and coherent activity of the organism is again enhanced. The corollary from this group of truths is one which will nearly concern us when we come to treat of the Evolution of Society: it is this,—the greater the amount of progress already made, the more rapidly must progress go on. CHAPTER XIV. LIFE AND MIND. BEFORE we proceed to treat of psychical life as the con- tinuous establishment of subjective relations that are in correspondence with environing objective relations, we must dispose of certain questions which have been raised by Comte and his disciples concerning the right of psychology to be regarded as an independent science. Part of Comte’s plan for the renovation of philosophy was the rescuing of psychology from the exclusive control of metaphysicians. The manner in which he proposed to accomplish the rescue is only too briefly described: he simply denied in toto the claims of psychology to be regarded as an independent science. According to Comte there can be no science, worthy of the name, founded upon the observation and comparison of states of consciousness; and psychology must therefore be studied as a part of biology, by the aid solely of the methods used in biology. That is, the study of mind must be reduced to the study of nervous phenomena simply. It is easy to say that the inevitable outcome of this is the unqualified assertion of materialism. But as Comte himself never drew such an inference, and always protested ener- getically against materialism, as based upon illegitimate inferences from the study of nervous phenomena, it would 74 COSMIC PHILOSOPHY. (pT. IL not be fair in us to draw the inference for him and then upbraid him with it. This kind of misrepresentation is dear to theologians, and we may contentedly leave them an entire monopoly of it. But worse remains behind. Having con- demned psychological analysis as useless, Comte offers us in exchange the ludicrous substitute—Phrenology ! Of all the scientific blunders which Comte ever made, this was beyond question the one which has done most to injure his credit with competent scientific critics. Yet in fairness we must remember that Comte’s ignorance of psychology was his weakest point, and that forty years ago, when the anatomy and physiology of the nervous system were in their infancy the conception of dividing the grey surface of the cerebrum into thirty or more provinces, each the seat of a complex group of mental aptitudes, did not seem so absurd as it does now. In those days even Broussais, a first-class physiologist, adopted some of the leading doctrines of phrenology. More- over the fundamental conception of Gall—which included the anatomical comparison ,of all animal brains, in con-~ nection with the study of the mental characteristics of animals—was a noble conception ; though in working it out he showed himself lamentably ignorant of the plainest rules of induction. The purposes of our inquiry do not render it necessary for me to discuss the merits of a hypothesis which has long since ceased to be of any interest, save as an episode in the early history of physiological psychology. Those who wish to see the question treated critically may be referred to the works of Miiller, Valentin, Wagner, Vulpian, Gratiolet, Longet, and especially of Lélut ; to “the appendix to Hamil- ton’s “Lectures on Metaphysics”; to the chapter on Gall in Mr, Lewes’s “History of Philosophy ” ; and to Mr. Bain’s treatise on “The Study of Character.” It is not Comte’s acceptance of phrenology, but his denial of psychology, which here concerns us. The former is merely a personal question, bearing upon Comte’s scientific com- oH. xI¥.] LIFE AND MIND, 75 petence; the latter is a question of general interest. We may note at the outset that many contemporary posi- tivists differ from ~Comte on this point. It is generally agreed that a science may be founded, even if it has not already been founded, upon the observation and comparison of states of consciousness; though there is some disagree- ment as to the position of that science with reference to tha, other sciences. Mr. Lewes, for instance, misled by his general adherence to the Comtean classification of the sciences, re- gards psychology as a subdivision of biology, on the ground that the phenomena of consciousness are merely a special division of the phenomena of life. This is, in one sense, true; so true, indeed,.as to be fatal to the conclusion which it is meant to support. For it may be said, with equal truth, that the phenomena of life are but a subdivision of the pheno- mena presented by the surface of our contracting and cooling planet; so that it might equally well be argued that biology | is only a subdivision of geology. And again it may be said that geologic phenomena are only a subdivision of the general phenomena presented by the condensation of a nebula; so that geology is only a branch of astronomy. Yet it could hardly be said that psychology is a mere branch of astro- nomy; so that here we seem to have reached a reductio ad absurdum. ) But by travelling back over the course, we shall get out of the difficulty, and not only see why psychology has as good a right as any other branch of inquiry to be ranked as an independent science, but also see why it must needs be partly founded upon an observation and comparison of states of consciousness. Let us then, having reached the primeval nebuia, begin our journey backwards. Our position is explained by the consideration that all the synthetic concrete sciences are but adjacent tracts of one general science,—Cosmology: “ Practically, however, they are distinguishable as successively more specialized parts of 78 COSMIC PHILOSOPHY. [er. 11. the total science—parts further specialized by the intro- duction of additional factors. The astronomy of the solar system is a specialized part of that general astronomy which includes our whole sidereal system; and becomes specialized by taking into account the revolutions and rotations of planets and satellites. Geology is a specialized part of this special astronomy ; and becomes specialized by joining with the effects of the earth’s molar motions, the effects of con- tinuous decrease in its internal molecular motion, and the effects of the molecular motion radiated from the sun. Bio- logy is a specialized part of geology, dealing with peculiar agorézates of peculiar chemical compounds formed of the earth’s superficial elements—ageregates which, while exposed to these same general forces molar and molecular, also exert certain general actions and reactions on one another. And psychology is a specialized part of biology, limited in its application to a higher division of these peculiar aggregates, and occupying itself exclusively with those special actions and reactions which they display, from instant to instant, in their converse with the special objects, animate and inani- mate, amid which they move.” ? This last point is one which requires further illustration. Concisely expressed, it amounts to this—that psychology is distinguished by dealing in a particular way with the rela- tions between the organism and its environment. A few illustrations will render this perfectly intelligible; will show us that mere nervous physiology is not, and never can be, psychology. Nervous physiology treats of relations subsisting within the organism. It explains how waves of molecular motion, set up in a nerve-centre and transmitted along a nerve-axis, cause contraction in the fibres of a muscle, or secretion in a eland, or molecular rearrangement in the substance of the tissues, or sets up a new molecular undulation in some other 1 Spencer, Principles of Psychology, vol. i. pp. 187, 138, CH. XIV. ] LIFE AND MIND. 77 nerve-centre. It seeks to formulate the conditions under which nervous stimulation and nervous discharge take place. Or it shows how certain feelings are invariably sequent upon certain rearrangements of the molecules composing the nerve- substance. Even if it recognizes, as it does continually recog- nize, some force external to the organism, which causes the molecular rearrangement and the resultant feeling, it never- theless does not concern itself with the relation between the external cause and the internal effect, but only with the internal effect. Now, as Mr. Spencer has forcibly pointed out, “so long as we state facts of which all the terms lie within the organism, our facts are anatomical or physiological, and in no degree psychological. Even though the relation with which we are dealing is that between a nervous change and a feeling, it is still not a psychological relation so long as the feeling is regarded merely as connected with the mervous change, and not as connected with some existence lying outside the organism. . . . For that which distinguishes psychology from the sciences on which it rests, is, that each of its propositions takes account both of the connected internal phenomena and of the connected external phenomena to which they refer, In a physiological proposition an inner relation is the essential subject of thought; but in a psychological proposition an outer relation is joined with it as a coessential subject of thought. A relation in the environment rises into coordinate importance with a relation in the organism. The thing con- templated is now a totally different thing. It is not the onnection between the internal phenomena, nor is it the connection between the external phenomena; but it is the connection between these two connections. A psychological pro- dosition is necessarily compounded of two propositions, of which one concerns the subject and the other concerns the object ; and cannot be expressed without the four terms which these two propositions imply. The distinction may be best 78 COSMIC PHILOSOPAY. (Pr. 1. explained by symbols. Suppose that a and B are two re lated manifestations in the environment—say, the colour and taste of a fruit; then, so long as we contemplate their rela- tion by itself, or as associated with other external phenomena, we are occupied with a portion of physical science. Now suppose that x and yY are the sensations produced in the organism by this peculiar light which the fruit reflects, and by the chemical action of its juice on the palate; then, so long as we study the action of the light on the retina and optic centres, and consider how the juice sets up in other centres a nervous change known as sweetness, we are occu- pied with facts belonging to the science of physiology. But we pass into the domain of psychology the moment we inquire how there comes to exist within the organism a rela- tion between X and Y that in some way or other corresponds to the relation between A and B. Psychology is exclusively concerned with this connection between AB and XY: it has to investigate its nature, its origin, and its meaning.”2 It is true, as the last chapter showed us, that biology also presupposes a reference to phenomena outside the organism, the very definition of Life being “the continuous adjustment of internal relations to external relations”; so that Mind here appears to be but the highest form of Life. We see here the difficulty of sharply demarcating adjacent provinces of na- ture. Nevertheless there is a broad distinction, though not a sharp one. Exclude from biological problems all those adjustments which constitute mental reaction upon the en- vironment, and the only external factors remaining are those general conditions of temperature, moisture, food and the like, which are taken for granted once for all. While in each special problem of psychology, the relation between internal end external relations is the main subject of inquiry ; on the other hand in special problems of biology, the relation be- tween the internal processes and these general external 1 Spencer, Principles of Psychology, vol. i. y. 132. pH. x1v.] LIFE AND MIND. 79 factors is not the chief, but a subordinate, subject of inquiry. Digestion, for instance, implies food; and “ food implies neighbouring plants or animals ; but this implication scarcely enters into our study of digestion, unless we ask the quite special question—how the digestive organs become fitted to the materials they have to act upon.” But a moment’s intro- spection will make it clear to everyone, “that he cannot frame any psychological conception without looking at in- ternal coexistences and sequences in their adjustments to ex- ternal coexistences and sequences. If he studies the simplest act of perception, as that of localizing a touch in some part of his skin, the indispensable terms of his inquiry are :-—on the one hand a thing (1) and a position (2), both of which he regards as objective ; and on the other hand a sensation (3), and a state of consciousness constituting his appreheusion of position (4), both of which he regards as subjective. Or, if he takes for his problem one of his complex sentiments, as that of justice, he cannot represent to himself this sentiment, or give any meaning to its name, without calling to mind actions and relations supposed to exist in the environment: neither this nor any other emotion can be aroused in con- sciousness even yaguely, without positing something beyond consciousness to which it refers.” } Let us observe, in passing, that these considerations are quite incompatible with Materialism. The doctrine of the materialists rests partly on the assumption that the study of the laws of nervous action can give us a complete account of mental phenomena. But we have seen that to understand the simplest act of perception, we must take into the account ..ot only the subjective and the objective factors, but the relation between the two. It is this relation which consti- tutes tne perception. But this relation exists only in con- sciousness, and we cannot explain it save by direct observation oi cousviousness. Push our researches in biology as tar as * Spencer, Principles of Psycholegy, vol. i. p- 133. 80 COSMIC PHILOSOPHY, fer. u we may, the most we can ever ascertain is that certain nerve- changes succeed certain other nerve-changes or certain ex- ternal stimuli in a certain definite order. But all this of itself can render no account of the simplest phenomenon of consciousness. As Mr. Spencer well says, “such words as ideas, feelings, memories, volitions, have acquired their several meanings through self-analysis, and the distinctions we make Letween sensations and emotions, or between automatic acts and voluutary acts, can be established only by comparisons among, and classifications of, our mental states. The thoughts and feelings which constitute a consciousness, and are abso- lutely inaccessible to any but the possessor of that cone sciousness, form an existence that has no place among the existences with which the rest of the sciences deal. Though accumulated observations and experiments have led us by a very indirect series of inferences to the belief that mind and nervous action are the subjective and objective faces of the same thing, we remain utterly incapable of seeing, and even of imagining, how the two are related. Mind still continues to us a something without any kinship to other things.” | Thus we conclude that psychology—though, from the objective point of view, it may be regarded as a branch of biology in the same abstract sense in which biology may be regarded as a branch of geology, and geology as a branch of astronomy—has nevertheless an equal claim with any of these to be ranked as a distinct science. From the sub- jective point of view it has a superior claim to any of the others. Since here the phenomena studied are directly given in the consciousness of the investigator, there arises a dis- tinction more fundamental than those by which the various departments of objective science are marked off from each other. And, indeed, without some of the data furnished by this unique subjective science, it is impossible to obtain the premises of philosophy; as will at once be admitted, on cH. XIVv.] LIFE AND MIND. 8] recollecting the topics which occupied us in the first part of this work. Psychology is therefore distinct alike from biology and from other sciences, in its problems and in its theorems, The problem of biology is to formulate the laws of nutri- ticn and reproduction, muscular contraction and nervous irlitation, heredity and adaptation. The problem of psy- chology is to formulate the laws of Association,—the order in which certain relations among environing phenomena give rise to certain corresponding relations among our states of consciousness. And while the theorems of objective science in general are based upon the observation of objective phe- nomena, whether external or internal to the organism; the theorems of psychology are based not only upon the obser- vation of objective phenomena, but also upon the observation | of subjective states. In view of these results, we see how hopelessly Comte went astray. Rejecting all introspection as metaphysical and delusive, he would have had us confine our inquiries to the succession of those nervous phenomena which are the invariable concomitants of feelings, ignoring the fact that without introspective observation we can never even ascertain that there 7s any invariable concomitance between the feel- ings and the nervous phenomena. He would have us solve » problem in which two factors are concerned, by investi- gating only one factor. In giving his reasons for thus rejecting all observation of consciousness, Comte reveals his inability (upon which I have already frequently remarked) to distinguish between psychology and metaphysics. He insists that psychologic inquiry, as hitherto conducted, has not resulted in discovery. If this were true, it would not help his case. Metaphysical )sychologists have failed in discovery, not because they have directly examined states of consciousness, but because they have constructed unverifiable hypothesus about the nature of Mind in itself, Where they have abstained from ontological VOL. IL G 82 COSMIC PHILOSOPHY, [PT. 31, inquiries, and have contented themselves with scientific methods, psychologists have made discoveries. To say nothing of such recent inquirers as Bain, Wundt, Fechner, and Taine, it may be fairly claimed that, among older specu~ lators, Hobbes, Locke, Leibnitz, Berkeley, Hume, Kant, and Hartley, have by psychologic analysis made real and per- manent contributions to our knowledge of mental operations. And at the very date when Comte was preparing his great treatise for publication, there appeared a remarkable book which, by establishing some of the fundamental laws of Association, went far toward placing psychology upon a scientific basis. It is not to the crude and superficial Gall, as Comte would have us believe, that we must give the respect due to the founder of scientific psychology: that respect is due, in far greater degree, to James Mill, the illus- trious author of the “ Analysis of the Human Mind.” Nevertheless, while psychology is a science clearly distinct from biology, dealing with phenomena which may be classed as super-organic, and using introspective observation as one of its main implements of inquiry, it is no more than any other an absolutely independent science. Since the pheno- mena of Mind are never manifested to us save in connection with the phenomena of Life, and since the same general formula expresses the fundamental characteristics of the two croups of phenomena, it follows that no complete science of psychology can be constituted without the aid of biology. The conclusions reached by the analysis of subjective states must be shown to be in harmony with the conclusions reached by the synthesis of objective phenomena, before the scientific interpretation of Mind can be regarded as entirely satisfactory. The force of this statement becomes at once’ apparent, when we recollect that introspective observation can inform us only concerning the mental. processes which go on in adult civilized men. In order to understand the genesis of these mental processes, we need the assistance of cn. xIv.] LIFE AND MIND. 83 objective psychology and of nervous physiology; we need to compare the mental processes observed in adult civilized men, with the mental processes observed or inferred in civilized children, in adult barbarians, and in the lower animals, down to those humble organisms in which the phe- nomena of intelligence first become differentiated from the phenomena of organic life. The immense advance which has been made in mental science during the past forty years, has been mainly due to the practical recognition of this fact. Treatises on psychology are no longer solely based upon an analysis of what happens when “I see the inkstand,” although analyses of this sort are still, as is here maintained, indispensable. The nervous system, in its ascending com- plications from the amphioxus to man, is now taken into the account. The normal variations in psychical manifes- tation, in the various human races, from childhood to old age, are taken into the account. The abnormal variations caused by stimulants and narcotics, as well as those ex- hibited in epilepsy, insanity, and other forms of nervous disease, are taken into the account. And careful investi- gations into the ways in which different organisms respond to external stimuli, show us that the lower forms of psy- chical activity are no longer neglected. While the analysis of complex mental operations has been pushed to an extent which until lately would have been deemed impracticable, on the other hand the sub-science of psychogeny, dealing with the origin of the various manifestations of mental activity, has arisen to coordinate importance with subjective ysychology. It has become generally recognized that—in- effaceable as is the distinction between the phenomena of consciousness and all other phenomena—nevertheless the one as well as the other can be scientifically explained, only when present manifestations are studied in their con- nection with past manifestations. In this domain, as in all others, the Law of Evolution holds sway. G2 84 COSMIO PHILOSOPHY, (pr. 11 Let us now, in accordance with these general considera- tions, begin by contemplating the phenomena of Mind as gradually differentiated from the phenomena of Life ; reserv- ing for another chapter the interpretation of sundry psycho- logical truths in terms of the law of evolution. And first let us reconsider the definition of life which was briefly illustrated in the preceding chapter. We saw that life essentially consists in the continuous adjustment of relations within the organism to relations in the environment. And we saw that the degree of life is low or high, according as the correspondence between internal and external relations is limited or extensive, partial or complete, simple or complex. We saw tnat the lowest forms of life respond to the changes going on about them only in a simple, imperfect, and general way. A tree, for instance, meeting by changes within itself none but physical and chemical changes which occur with general uniformity in the environment, exhibits life in a very simple and unobtrusive form. We habitually regard it as less alive than a polyp, because the polyp, by displaying nascent sensitiveness and contractility, responds to a greater variety of more special external stimuli. Yet the polyp, possessing no specialized organs of sense, can oppose but one sort of action to many diverse kinds of impression. [heno- mena so different as those of light and heat, sound and mechanical impact, can affect it in but one or two ways,—by sausing it to move, or by slightly altering its chemical con- dition. The modes of response to outer relations are few and homogeneous. Passing abruptly to civilized man, at the other eud of the animal scale, we find a different state of things. To each kind of external stimulus there are many possible modes of response. Not only, for example, does the human organism sharply distinguish between variations which altect the eye and those which affect the ear; not only co eye aud ear, which are themselves organs of ainazine com- plexity, discern an endless number of differing tones and cH. Xtv.] LIFE AND MIND. 85 hues, as well as a great variety of intensities and qualities ; but each particular manifestation of sound or of light is capable of arousing in the organism very different psychical combinations, entailing different muscular actions, according to circumstances. Tennyson’s traveller, who, walking at nightfall in a strange land, hears the moaning of a distant sea, * And knows not if it be thunder, or a sound Of rocks thrown down, or one deep cry Of great wild beasts,” will adopt a course of action more or less in conformity with environing relations, according to the degree of his sagacity and the extent of his experience. Streaks of light and strata of cloud in the horizon will lead the practised mariner and the unskilled passenger to different conclusions. A cartoon of Raphael or a symphony of Beethoven will excite different emotions in an artist and in a person of feeble impressibility. And from the swinging of a cathedral lamp the young Galileo drew inferences which had escaped the attention or baffled the penetration of thousands of less acute beholders. Thus, with civilized man, the modes of response to outer relations are almost infinitely numerous and heterogeneous. But now, in this briefly indicated contrast between the lowest and highest extremes of life, regarded as a correspond- ence between the organism and the environment, we have jassed abruptly from vital relations which are purely physical to vital relations which are almost purely psychical. The relations contemplated have been, in each of the instances, relations internally set up in adjustment to external relations. But while the relations set up within the tree are simply physico-chemical; and while the relations set up within the polyp, thovgh involving nascent sensitiveness, are neverthe- less, in the absence of specialized nerve-matter, unattended by consciousness, and therefore cannot strictly be classed as psychical; on the other hand, the relations set up within 86 COSMIC PHILOSOPHY. [PT. IL civilized man are almost purely psychical, involving only such physico-chemical elements as are necessitated by the fact that conscious activity does not yo on unattended by molecular changes in nerve-tissue. It appears, therefore, that while in the vegetal world, and in the lower regions of the animal world, the life is purely or almost purely physico-chemical, it becomes more and more predominantly psychical as we ascend in the animal world, until at the summit it is mainly _ psychical, The continuous adjustment of inner to outer relations, which both constitutes life and maintains it from moment to moment, is a process which, at first purely physiological, becomes ever more distinctly psychological. From the facts of comparative anatomy we may elicit a parallel truth. In standard works on human anatomy it is customary to distinguish between the vegetative organs, (com- prising the nutritive and reproductive systems,) which are developed from the endoderm of the embryo, and the animal organs, (comprising the nervo-muscular system,) which are developed from the ectoderm. Not unfrequently these are otherwise and more appropriately distinguished as the nutritive and relational systems; the special office of the former being the integration of nutritive material, in behoof either of the organism or of its derivative offspring, while the special office of the latter is the maintenance of relations between the organism and the environment. The demarca- tion is thoroughly distinct, but it is not absolute; since the relations each moment set up even in the nutritive system must correspond with certain general relations of air, temperature, and assimilable material in the environment, Now we have to note that in the vegetal world such general correspondences are all that are established; there is no system of organs differentiated for the purpose of maintaining an equilibrium of relations with the environment. In such simply organized animals as the polyp there is no differentia- tion of relational tissues or organs; but the entire surface of CH. XIV.] LIFE AND MIND. 87 the animal, besides maintaining such general correspondences as characterize vegetal life, exhibits in a slight degree the irritability and contractility which in higher creatures are— specialized in those tissues which form the relational organs. In the molluscoida, the property of irritability being localized in a few nerve-threads uniting in ganglionic masses, and the property of contractility being specialized in a_ parallel manner, there is rendered possible that more special mode of response to environing agencies, known as reflex action. In the lower vertebrata, the integration of numerous adjacent ganglia into a medulla, having connections with various parts of the organism, renders possible a much more perfectly coordinated series of responses to external stimuli. And at the same time the development of a pair of pedunculated ganglia from the upper portion of the medulla, is attended by the ability to compound the impressions which the medulla receives; so that it becomes possible for the correspondences to extend in space and time. As we ascend through the vertebrate sub-kingdom, the growth of these pedunculated ganglia—the cerebrum and cerebellum—becomes more and more the predominant characteristic of the nervous system ; and at the same time the power of adjusting inner relations to remote, special, and complex relations increases. Finally when we come to man, in whom the correspondences have reached a marvellous degree of heterogeneity, extent, and de- finiteness, we find not only that the relational system of organs is the dominant fact in his organization, but also thatthe system of pedunculated cephalic ganglia is the dominant fact in the relational system of organs. Not only is the nutritive life quite subordinated to the specially relational life, but the lower modes of the relational life, such as reflex action and instinct, are quite subordinated to those higher modes, such as thought and emotion, which are made possible by the great extent to which the cerebrum and cerebellum carry the compounding of impressions received in the medulla. In 88 COSMIC PHILOSOPHY, [PT. 11 order to realize with vividness how comyletely human life has come to mean the higher psychical life, let us try to imagine what life would be without the cerekrum and cerebellum Yet from the biological point of view these systems of ganglia though nearly, are not quite, absolutely essential to human life; since the less complex acts and impressions are still coordinated after they have been destroyed by disease, and since infants, born without any brain save the medulla and basal ganglia, have been known to live for a short time. Such a deprivation of the higher relational activities naturally seems to us almost equivalent to deprivation of life. We may now more thoroughly appreciate the force of the distinction between the provinces of biology and of psy- chology, which was stated in the earlier part of this chapter. We see that while life, physical and psychical, is the con- tinuous adjustment of inner to outer relations, nevertheless in the lowest forms of life, unaccompanied by mind, the outer relations to which adjustment is made are exceedingly general, and the correspondence is simple, direct and homo- geneous. But as we pass to forms somewhat higher, we find, along with this simple correspondence maintained by the whole organism, a number of more complex, indirect, and special correspondences, for the establishinent and main- - tenance of which there is differentiated a particular relational structure. As the correspondence increases in complexity, in indirectness, and in speciality, the maintenance of it is confined more and more to this specialized nervo-muscular structure; and the enormously heterogeneous series of ad- justments which eventually goes on becomes distinguished , from the relatively homogeneous series of adjustments which : has all along been going on, as psychical life in contrast with physical life. Thus by a regular process of evolution it happens that, while at the outset the psychical life is but a slight extension of the correspondence which constitutes the physical life, at the end the correspondence which con ete mnet ras. 3 Coe, ae cH. XIV.] LIFE AND MIND. 89 stitutes the psychical life is all in all, and the processes of physical life come to be regarded as entirely subordinate to the maintenance of this higher correspondence. Let us now briefly trace the various extensions and com- plications of the correspondence as it becomes more hetero- geneous, definite, and coherent. Scanty justice can here be done to the subject, since it is necessary for me to compress into half-a-dozen pages the substance of a series of illus- trations, which in Mr. Spencer’s exceedingly condensed exposition fill a hundred pages. Nevertheless a few striking facts may be noted down, which will serve to assist in the comprehension of the process. Let us first note that in the simplest forms of life the correspondence extends “only to external relations which have one or both terms in contact with the organism. The processes going on in the yeast- plant cease unless its cell-wall is bathed by the saccharine and other matters on whose affinities they depend... . And so too among the lowest animals, the substances to be assimilated ‘must come in collision with the organism before ‘any correspondence between inner and outer changes is shown.” . The correspondence is similarly limited in time. The tree, which puts forth its leaves from year to year, does so only in response to luminous and thermal changes which occur contemporaneously. The polyp’s tentacles contract only in response to immediately present stimuli. “ Alike in all these forms of life, there is an-absence of that correspondence between internal relations and distant external relations ”— in space and time—which we see exhibited in higher forms. , Now the extension of the correspondence in space is effected by the gradual differentiation of organs of sense. One of the most notable achievements of modern biology is the discovery—due among others, to Huschke, Remak, Milne-Edwards, and Huxley—that all the sense-organs are but successive modifications of tactile structures, or rather, of those simple dermal structures which in the higher 90 COSMIC PHILOSOPHY. [Pr. 11. organisms are specialized as tactile. The most perfect organs of touch are the vibrisse or whiskers of the cat, which act as long levers in communicating impulses to the nerve-fibres that terminate in clusters about the dermal sacs in which they are inserted. Yet these whiskers are merely specialized forms of just such hairs as those which cover the bodies of most mammals, and which are found evanescent upon the human skin, embedded in minute sacs or re-entrant folds. Now it is a demonstrated fact that the eye and ear are morphologically identical with vibrisse. The bulb of the eye and the auditory chamber are nothing but extremely-metamorphosed hair-sacs, and the same is true of the olfactory chamber. The crystalline lens is a differentiated hair, the aqueous and vitreous humours are liquefied dermal tissue, and the otolites of the ear are “ concretions from the contents of an epidermic sac.” In view of these astounding disclosures of embryology, we may readily assent to Mr. Spencer’s statement that modern science justifies the guess of Demokritos, “that all the senses are modifications of touch.” From a single sense, more or less diffused over the surface of the body, and capable of establishing correspondences only with agencies in direct contact with the body, there have arisen, by slow differentiations, such localized senses as sight and hearing, which serve to enlarge the environment and establish correspondences with agencies more and more re- mote. Let us briefly consider the sense of sight, omitting hearing, as well as smell and taste, since our space is too limited to deal with them properly. In such lowly organized creatures as the hydra the ability to distinguish between light and darkness, or between sun- shine and shadow, is possessed in a slight degree by the entire surface of the body. But vision can hardly be said to exist, even in its most rudimentary aspect, until this sensibility is “concentrated in a particular spot. The rudi- mentary eye consisting, as in a planaria, of some pigment CH, Xiv.] LIFE AND MIND, 91 grains, may be considered as simply a part of the surface more irritable by light than the rest. Some idea of the impression it is fitted to ‘receive may be formed by turning our closed eyes towards the light, and passing the hand backwards and forwards before them.” But while this localization of sen- sibility enables the creature to adapt itself to the movements of neighbouring opaque bodies, the extension of the corre- spondence is nevertheless very slight. To produce noticeable obscuration the opaque object must approach very near; and hence “we may infer that nascent vision extends to those objects alone which are just about to touch the organism, . . so that it amounts at first to little more than anti- cipatory touch.”* As we pass to higher forms, we find the eye gradually increasing in translucence, acquiring convexity of surface, liquefying internally into refracting humours, while the nerve-vesicles within multiply and arrange them- selves as retinal rods; the result being seen in the gradually increasing power of the organism to adapt its actions to actions occurring at a distance. The process and the result of development are essentially the same in the case of hearing and smell, though there are great differences in the degrees to which these senses are developed in the highest animals, Further extension of the correspondence is effected, in the higher vertebrates, by the increase in size and complexity of the cerebrum and cerebellum. These pedunculated groups of ganglia, which issue from the medulla, and whose function it is to compound in higher and higher aggregates the already-compound impressions received by the medulla, are capable of adjusting inner relations to outer relations beyond the reach of the organs of sense. “Chased animals that make their way across the country to places of refuge out of view, are obviously led by combinations of past and present impressions which enable them to transcend the sphere of the 4 Spencer, Principles of Psychology, vol. i. pp. 314, 815. 2 COSMIC PHILOSOPHY, [Pr. 11. senses.” And in man, by the aid of science, the correspon- dence is extended not only over the entire surface of the earth, but through all visible space ; witness the facts that telegraphic reports enable purchasers in New York to adapt their actions to prices in London, and that the inferences of astronomers are modified in accordance with chemical changes going on in remote nebule. Along with the extension of the correspondence in space there goes on an extension in time, resulting in an enormous increase of the psychical life. Under their more simple forms the two kinds of extension go on together. The rudimentary — eye, which enables the organism to anticipate the contact of an approaching opaque body, may serve to illustrate the primitive connection between adjustments to external co- existences and adjustments to external sequences. And it is obvious, without concrete illustration, that in general the more remote are the outer relations to which inner relations are adjusted, the longer will be the interval by which the adjustment may be made to anticipate the group of outer relations which it is designed to balance, But it is only in the higher vertebrates, whose cephalic ganglia are sufficiently large and complex to enable them to form ideal representa- tions of outer relations not immediately present, that there is witnessed a decided extension of the correspondence in time. Dogs and foxes exhibit a well-marked anticipation of future events, in hiding food to be eaten hereafter. But it is first in the human race that such foresight becomes highly con- sSpicuous ; and the difference between civilized and savage men in this respect is probably even more marked than the difference between savage men and the higher allied mam- mals. There are strong reasons for believing that the more complex correspondences in time are chiefly effected by the cerebrum, while the more complex correspondences in space are chiefly effected by the cerebellum. And if this be the case, we may understand why it *s that in the course ol ru. xiv.] LIVE AND MIND. 93 human progress the increase of the cerebrum in size and complexity has been so much greater than the increase of the cerebellum. In no other respect is civilized man so widely distinguished from the savage, as in his habitual adjustment of his daily actions to contingencies likely to arise in a more or less distant future. But here we touch upon an important theorem of sociology, which I shall here- after consider at greater length. Next let us note that the extension of the correspondence in space and in time is accompanied by a progressive increase in the speciality of the correspondence. Manifestly the differentiation of sense-organs which renders possible the adjustment of inner relations to distant outer relations, also renders possible the adjustment of inner relations to outer relations that are more and more special. Increased width of retina enhances the power of estimating the size of neigh- bouring objects, since the differences in the visual areas which they occupy will become more clearly appreciable. The multiplication of retinal rods enhances the power of estimat- ing shape, since differently shaped objects affect different numbers and different combinations of these rods. Thus while animals with rudimentary vision, in becoming aware of the presence of approaching objects, can recognize them only as objects, on the other hand an animal with developed vision, in recognizing objects near or distant, can also distinguish between innumerable differences in their sizes and shapes, and can make a proportionally great number of special adaptations in its conduct. It is similar with the ability to distinguish colours, and to estimate direction by the cye. And from the growing heterogeneity of the other senses, we might draw parallel illustrations, were there room for them. Finally the high development of the cephalic ganglia, rendering possible the compounding of ideal repre- sentations of objects and relations not present to sense, increases to an enormous degree the speciality of the adjust- 84 COSMIC PHILOSOPHY, [Pr. 11. ments, Such special adjustments are seen in the cases of “the lion that goes to the river-side at dusk to lie in wait for creatures coming to drink, and the house-dog standing outside the door in expectation that some one will presently open it.” But the increase in speciality of adjustment is most con- spicuously exemplified in the progress of the human race; as is seen by contrasting the savage who sharpens his arrows in expectation of the periodic flight of certain birds, with the astronomer who at a given day, hour, and minute, adjusts his telescope to watch a transit of Venus. In the life of the highest animals, and especially in the life of the human race, characterized as it is by the predomin- ant activity of the great cephalic ganglia, there is witnessed an increase in the generality of the correspondence, parallel with the increase in speciality. As this topic falls almost entirely within the province of sociology, the illustration of it must be reserved for a future chapter. Let it here suffice to recall the fact, already mentioned, (Part I. Chap. viii.,) that the progress of human knowledge has all along been equally characterized by analysis and by synthesis,—by the differentiation implied in the recognition of relations that are more and more special, as well as by the integration implied in the grouping of relations in classes that are more and more general. Along with the increase of the correspondence in spatial and temporal remoteness, in speciality and in generality, there is a continuous increase in complexity. Indeed, in the various aspects of psychical progress already contemplated, this aspect has been continually illustrated. Obviously the development of sense-organs, while widening the environ- ment and increasing the number of relations to which the organism may adjust itself, enhances also the complexity of the adjustments, Contrast the simple movements of the planaria when an opaque object passes before its rudimentary eye, with the complex movements of a cat when a mouse ig cH. xIv.] LIFE AND MIND. 95 heard scratching in the wainscot, and it becomes evident that the heterogeneity of the impressions received by an organism is paralleled by the heterogeneity of the adjustmeats by which it responds to them. The multiplication of the objects and relations of which any organism can take cognizance, involves of necessity a growing complexity in the actions by which it adapts itself to their presence. In civilized man, whose immensely developed cephalic ganglia bear witness to the predominance of psychical over physical life, this correlated advance in heterogeneity of correspondence is exemplified in the interdependent progress of science and art. Here again we are carried into the domain of sociology, and this thread must be left to be gathered up with the others when we come to treat of intellectual progress. It remains to note that the extension of the correspondence in space and time, and its increase in definite heterogeneity, both heighten the degree of life and add to the ability to maintain life. On the one hand, the more numerous, the more complicated, and the more clearly defined, are the outer relations to which the organism adapts itself, and the longer the interval of time by which the adjustments may be made to forestall external contingencies, the greater will be the number of heterogeneous changes in which life consists. And on the other hand, the greater the number of hetero- geneous changes by which the organism can respond to outer ehanges, the more easily and surely will life be prolonged. Whence, says Mr. Spencer, “we may clearly see how life and ability to maintain life, are two sides of the same fact— how life is a combination of processes, the result of whose workings is their own continuance.” An interesting com- nentary on this proposition is furnished by Mr. Lankester’s recently-published essay on “Comparative Longevity,” in which it is shown that high individuation, or the power of responding heterogeneously to external changes, is the chief, though not the sole, factor concerned in producing length eS COSMIC PHILOSOPHY. [PT. 1. of life. The amount of normal longevity in any species depends upon the definite heterogeneity of the adaptation of its individual members to environing circumstances, and also upon the ratio of their nutrition to their expenditure. But the preponderant importance of the former factor is seen in the fact that, in spite of their immensely greater personal expenditure, the higher animals are, as a rule, very much longer lived than the lower ones. In the civilized human races also, as contrasted with the savage races, the life is not only higher in degree but longer in duration: the longevity of the lowest savages rarely exceeds forty-five — years. As we proceed to survey, in a single view, the various truths here separately elucidated, we find that the essential distinction, above insisted on, between the sciences of biology and psychology, is thoroughly justified by the very facts which illustrate the close connection between the two. The foregoing exposition conclusively proves that in dealing with the adjustments of inner to outer actions, biology “limits itself to the few in which the. outer actions are those of agents in actual contact with the organism—food, aerated medium, and things which produce certain effects by touch (as insects which fertilize flowers); thus leaving to psy- chology all other adjustments of inner to outer actions.” “The moment we rose to a type of creature which adjusts certain organic relations to relations of which both terms are not presented to its surface, we passed into adjust- ments of the psychological order. As soon as there exists a rudimentary eye capable of receiving an impression from a moving object about to strike the organism, and so ren- dering it possible for the crganism to make some adapted movement, there is shown the dawn of actions which we distinguish as intelligent. As soon as the organism, feebly sensitive to a jar or vibration propagated through its medium contracts itself so as to be in less danger from the adjacent sof istedvanca, we perceive a nascent form of the life | cares as psychical. That is to say, whenever the corre- j ‘spondence exhibits some extension in space or in time, some ro _ increase of speciality or complexity, we find we have crossed oe : ‘the boundary between physical life and psychical life”? _ ; aie Be" i scoue, Priscigles of Pojcheligag wk Lp ale a CHAPTER XV. THE COMPOSITION OF MIND. In pursuing the analysis of a complex series of phenomena, with the object of ascertaining the simple ultimate elements of which the complex series is made up, we shall sometimes most satisfactorily accomplish our purpose if we begin with the most complicated cases which the series presents. After explaining these by resolving them into their less complex components, our analysis “ must proceed similarly with these components; and so, by successive decompositions, must descend to the simpler and more general, reaching at last the simplest and mst general.” Let us proceed, after this fashion, to inquire into the Composition of Mind. Begin- ning with the most highly-involved operations of conscious intelligence, and neglecting, for the time being, the con- sideration of those emotional states by which all operations of intelligence are to a greater or less degree accompanied, let us pursue our analysis until we have arrived at those ultimate units of feeling in the manifold compounding of which all con- scious operations, whether intellectual or emotional, consist. Beginning, then, with a somewhat complicated operation of intelligence, let us consider the process by which an as- tronomer, knowing the dimensions of the earth, is enabled to ealculate therefrom the distance of the moon. He must, in cH, Xv.] THE COMPOSITION OF MIND. 99 the first place, assimilate in thought the case of the moon to like cases in which the distances of inaccessible objects upon the earth are indirectly measured. When a land-surveyor wishes to ascertain the distance of a church-tower situated ‘on the farther side of a river, he has recourse to an indirect method of measurement. Upon his own side of the river he first measures the distance between two points sufficiently removed from each other, and this distance he calls a base- line. From each end of the base-line he now takes a sight at the inaccessible tower, and, with the proper instruments, measures the difference between its direction and the direc- tion of the base-line. In this way he obtains an ideal triangle, of which the tower is the apex; and, knowing the length of the base-line, and the value of the two angles at the ends of the base-line he calculates by trigonometry the length of the two sides which express the distance of the tower from the ends of the base-line. Now, the astronomer, imitating this process, assumes as a base-line the known distance between two remote points on the earth’s surface, as for example London and Cape Town; and then from each of these points he proceeds to take the bearings of the moon. The process, indeed, is here complicated by the fact that, owing to the long distance, the inequalities of the earth’s surface, and its curvature, the observer at Cape Town cannot see the position of London, and vice versd. It is necessary, therefore, again to resort to an indirect method, and, having measured the meridional bearings of the moon from the north-pole at London and from the south-pole at Cape Town, to compare these bearings with the knowledge that the bearing of the one pole from the other is 180 degrees or two right angles, A further correction must be made for the fact that London and Cape Town are not on the same meridian, But disre- garding these steps in the process, as unnecessarily com- piicating our case, we have to note that, when the astronomer has thus indirectly measured the angles which ideal lines H 2 100 COSMIC PHILOSOPHY. (Pr. 1: drawn to the moon must make at the two ends of his long base-line from London to Cape Town, he is at once enabled, like the land-surveyor, to calculate by trigonometry the lengths of these ideal lines, and thus to ascertain the moon’s distance. What, now, is the essential characteristic of the process which the astronomer goes through? Or, in other words, what is the fundamental psychical process by the mani- fold compounding of which is built up this highly-complex series of inferences ? From beginning to end, the fundamental process is the cognition of the equality of sundry relations, The thought | which underlies and determines the whole calculation is the cognition that the relations between the sides and angles of a great triangle, having for its apex the moon, and for its base the chord of the are of the meridian of London measured to a point in the southern hemisphere upon the same parallel with Cape Town, are equal to the relations between the sides and angles of a similar small triangle, having an inaccessible tower for its apex and a measured line of five or six rods for its base; and that these relations, in turn, are equal to the relations between the sides and angles of a still smaller and similar triangle which may be drawn on a sheet of paper, and of which the sides and angles may, if necessary, be directly measured. Now, this cognition implies the previous establish- ment, in the calculator’s mind, of sundry cognitions of the ejualities and inequalities of certain relations between the sides and angles of triangles. To show briefly how such cognitions have been established, let us cite the simplest case —that in which the two angles at the base of an isosceles triangle are recognized as equal to each other. Euclid es- tablishes this point by supposing two similar and equal isoscelas triangles, of which the oneis turned over and placed upon the other, so that the apex and one side of the one will coincide with the apex and opposite side of the other. Then the other sides and the bases must respectively coincide Tai he vu. Xv.] THE COMPOSITION OF MIND. 101 otherwise the two triingles would not be similar and equal, and the conditions of the case would be violated. Ali the sides being thus equal, each to each, the two triangles must everywhere coincide, and consequently the two basal angles must be equal, both in the triangle which has been turned over and in the one which has kept its original position. Now, each step of this demonstration is a cognition of the equality of a pair of relations of length or of direction; and in each case this cognition is established, not by any anterior demonstration, but by direct inspection. Or, in other words, when it is said that two lines of equal length, starting from the same point, and running in the same direction, must coincide at their farther extremities, the truth of the state- ment is at once recognized simply because the states of con- sciousness which we call the ideas of the two lines are totally indistinguishable from each other. This immediate perception of the equality—or, in some cases, of the inequality—between two or more relations of position or magnitude is the goal toward which every geometrical demonstration tends. And, still more, it is the mental act implied in every step of every such demonstration. All the devices familiar to the reader of Euclid—the bisecting of lines and angles, the drawing of parallels and the circumscribing of circles for argumentative purposes—are simply devices for bringing a given pair of space-relations directly. into consciousness, so that their equality or inequality may be recognized by direct inspection. Manifestly the case is the same in that algebraic reasoning which our astronomer will often find it desirable to employ in the course of his computation of the moon’s distance. The axiom that “relations which are equal to the same rela- tion are equal to each other” is an axiom which twice involves the immediate recognition of the equality of two given relations. And, if any proof were needed that the whole science of algebra is based upon this axiom, it may be found in one of the most common algebraic artifices “When a 102 COSMIC PHILOSOPHY. (Pr. 11, simplification may be thereby achieved, it is usual to throw any two forms of an equation into a proportion—a procedure in which the equality of the relations is specifically asserted.” To cite Mr. Spencer’s simple illustration: if we take any equation, 2 xy=y?, and, dividing it by y, obtain a second equation, 2 x=y, the legitimacy of our proceeding is at once rendered apparent when the two equations are thrown together in a proportion, in which it is asserted that the ratio of 2 zy to y* is equal to the ratio of 2z2to y. Or, if any doubt still remain as to the correctness of this, we resort to the familiar device of multiplying extremes and means, and obtain the identical proposition 2 ay’? =2 ay*,in which the identity of the two terms is immediately cognized, because the states of con- sciousness which they evoke are indistinguishable from one another. Thus the complicated quantitative reasoning by which an astronomer determines the distance of a heavenly body con- sists in the long-continued compounding of immediate cogni- tions of the equality or inequality of two or more given relations or groups of relations of position and magnitude. Before proceeding to unfold all that is implied by this conclusion, let us consider another concrete example of a somewhat different kind. "When acertain horned animal, of slender figure, with cloven hoofs, and a hairy integument, is presented to the inspection of a naturalist, he at once re- cognizes it as a giraffe; and, if required further to describe it, he observes that, as having four ‘stomachs and chewing the cud, it belongs to the sub-order of ruminants; as having its toes firmly united in a solid hoof, it belongs to the order of ungulata; as having mammary glands and suckling its young, it belongs to the class of mammals; and, as having an internal bony skeleton, it belongs to the sub-kingdom of vertebrates. What, now, is the mental act which is repeated at each stage of this description? It is “a cognition of the fact that the relation between particular attributes in this tn. Xv.] THE COMPOSITION OF MIND. 103 animal is like the relation between homologous attributes in certain other animals.” To confine ourselves to the first clause of the description—“the attributes implied by the term ruminant can be known only as previously observed or described ; and the predication of these, as possessed by the animal under remark, is the predication of attributes like certain before-known attributes. Once more, there is no assignable reason why, in this particular case, a relation of coexistence should be thought, between ‘ such attributes as the possession of four stomachs and the possession of horns and cloven hoofs,’ unless as being like certain relations of coexistence previously known ; and, whether the thinking of this relation can be otherwise accounted for or not, it is clear that the predication cannot otherwise have any probability, much less certainty.”! The case is the same with the re- maining clauses of the description, In each instance the mental operation performed by the naturalist is the recogni- tion of the likeness between certain groups of relations observed in this giraffe and certain other groups of relations previously classified as pertaining to ruminants, ungulata, mammals, and vertebrates. Obviously, therefore, the reason- ing by which the places of animals in the zoological scale are determined, consists in the compounding of cognitions of likeness or unlikeness between certain given groups of relations. So far, then, the mental] operation performed by the natu- ralist seems to be not unlike that performed by the astro- nomer. And indeed, in spite of the superficial difference ’ which seems so widely to separate the classification of animals from the measurement of celestial spaces, it will appear, on a moment’s reflection, that the only real difference between the mental processes involved in the former case, and those involved in the latter, is the extent to which Jae- ness is predicated of the relations concerned. Deeply con 3 Spencer, Principles of Psychology, vol. ii. p. 69. 104 _ COSMIC PHILOSOPHY, [PT. ls, sidered, the act of the astronomer is the same as that of the naturalist, save that, while the former classifies together sundry groups of relations as equal to one another, or indistin- guishable from one another, the latter classifies together sundry groups of relations as dike one another, or but slightly distinguishable from one another. Now; in this statement we see that what is meant by equality is merely exact like- ness ; but something more is needed for the accurate descrip- tion of the difference between the two cases. The objects which the astronomer contemplates are simple triangles, presenting simple relations of position and magnitude; while the objects contemplated by the naturalist are com- plex organisms, presenting immensely compounded relations of structure and function. Now, in speaking of simple things or simple relations, such as lengths and breadths, weights, times, and velocities, we habitually predicate equality or inequality of them. “ Wherever the terms of the comparison, being both elementary, have only one aspect under which they can be regarded, and can he specifically posited as either distinguishable or indistinguishable, we call them either wnequal or equal. But when we pass to complex things, exhibiting at once the attributes, size, form, colour, weight, texture, hardness—things which, if equal in some particulars, are rarely equal in all, and therefore rarely indistinguishable —then we use the term Jike to express, partly the approximate equality of the several attributes separately considered, and partly the grouping of them in a parallel manner in time and space. Similarly with the relations involved in reasoning. If simple, they are recognized as equal or unequal; if com- plex, as lke or unlike,” 7 The essential difference, then, between the quantitative rea- soning employed in the most advanced sciences, and the qualitative reasoning employed in those which are less ad- vanced, may be thus stated: in the first case the relations contemplated are so simple that they may be directly juxta CH. xVv.] THE COMPOSITION OF MIND. 105 posed in consciousness, and recognized as equal or unequal ; but in the second case the relations contemplated consist of so many simple relations heterogeneously combined, that they can only through a very indirect process be juxtaposed in consciousness, and hence are only approximately recognized as like or unlike. That this is the only essential difference between quantitative reasoning and qualitative reasoning is shown by the fact that all qualitative reasoning is vaguely quantitative, while all quantitative reasoning begins by be-ng qualitative. For example—to cite Mr. Spencer’s admirable illustration—when a brewer describes a vat of fermenting wort as containing carbonic acid, he makes a qualitative statement ; yet some rude notion of quantity is involved in it. “He thinks of the carbonic acid as more, certainly, than a eubic foot; less, certainly, than the total capacity of the vat: the quantity is thought of as in some ratio to the quantity of wort.” On the other hand, “a man who has walked a mile in fifteen minutes, and, observing that he has a quarter of a mile still to go, infers the time it will take to reach his desti- nation, does not primarily infer three minutes and three quarters : he primarily infers a short time—a time indefinitely conceived as certainly less than ten minutes, and certainly more than one.” Doubtless he may in an instant proceed to calculate the exact length of the time; yet, as it will not be denied that even before calculating he has a vague notion of the interval, it must be admitted that his inference, though ultimately quantitative, is, at the outset, only qualitative. Between the two kinds of reasoning, therefore, the only differ- ence is the degree of definiteness to which they are re- spectively developed. Bearing in mind these mutually harmonious conclusions— which alike imply the assertion that, between the highest and the lowest kinds of reasoning employed by civilized man, the difference consists solely in the complexity of the relations contemplated, and in the greater or less definitcness with 106 COSMIC PHILOSUPHY. [rT. II. which these relations are cognized as equal or unequal, like or unlike—let us now advance a step farther. Already, in the course of the foregoing analysis, the essential similarity between reasoning and classification has been vividly brought before us. We have now to scrutinize this similarity some- what more closely. To cite an example with which we are already familiar; when our astronomer, some thirty years ago, observed that certain irregularities in the motions of Uranus still remained unaccounted for, after calculating the combined effects of all the interior planets in producing such irregu-_ larities, it occurred to him that the unexplained irregularities could only be due to the gravitative force of some undisco- vered planet outside of Uranus; and the discovery of Nep- tune was the result of this most brilliant hypothesis. Now, the mental act involved in this deduction was essentially a classification of cases. The case of the unexplained pertur- bations was mentally ranked along with the several cases of explained perturbations presented by the solar system, as being similarly due to gravitative force; and to the number of known cases in which planets deflect each other from the regular paths in which they would otherwise move, a new hypothetical case was added. Comparing, now, this mental operation with that of the naturalist who, by virtue of certain observed likenesses of structure and function, ranks together lions, and elephants, and seals, in the class of mammals, we may conclude roughly that the one process consists in the formation of a group of like cases, while the other consists in the formation of a group of like things. And since by the expression “‘like cases” we mean merely “ like sets of rela- tions among two or more given groups of things,” it follows that we may characterize Reasoning as the classification of . relations, while Classification, ordinarily so called, is the classi- fication of things. When, for example, on perceiving two similar triangles set side by side, we proceed to make some CH. Xv.] THE COMPOSITION OF MIND, 107 inference from the known value of a side in the one to the desired value of the corresponding side in the other, the act ig an act of reasoning. But when, on taking up two similar sea-shells, we recognize them in their totality as belonging to an oyster or some other familiar mollusk, the act is an act of classification, commonly so called. In other words, if the perception of similarity is followed by the thought of one or more of the like relations which make up simi- larity, we have an act of reasoning; but if it is followed by the thought of other objects presenting like relations of similarity to the one now perceived, we have an act of classification. But, closely related as these two mental operations are now seen to be, we have not yet disclosed the full extent to which they are related. Not only is classification involved in every act of. reasoning or inference, but reasoning or inference is involved in every act of classification. Not only does reasoning consist in the grouping of relations as like or unlike, but the classification of things can go on only through the grouping of relations as like or unlike. To illustrate this, let us take a further downward step, and consider a mental operation apparently much simpler than those hitherto treated. Let us consider what is implied by the perception of an object. It is admitted on all sides that the perception of an object necessarily implies the recognition of the object as this or ‘hat, as iike certain objects, and as unlike certain other objects. Every act of perception, therefore, involves classi- fication. We cannot even name a chair without implying the existence of a group of objects which the chair resembles; and the essential element in the perception of a chair is not the reception of a group of visual or tactual impressions, but the interpretation of these impressions as like other ante- cedent impressions which, taken together, constitute the consciousness of the presence of a chair. And this is as 108 COSMIC PHILOSOPHY. [Pr. 1% much an act of classification, as the act by virtue cf which the naturalist would rank a newly-found horned and cloven- hoofed mammal among the ruminants; the only difference being that in ordinary perception the act has been per- formed so frequently as to have become automatic at an early period of life, while in scientific classification the act involves more or less conscious thinking, and comparison of relations. Here, in this last clause, there is hinted what we are seek- ing for. Not only in scientific classification, but in ordinary perception also, there must go on a comparison of relations, and a grouping of them as like or unlike. In perceiving an apple, for example, “the bulk is perceived to be like the bulk of apples in general; the form like their forms; the colour like their colours; the surface like their surfaces; and so on.” For if the bulk were like that of a water-melon, or if the shape were cubical, or if the colour were inky black, or if the surface were covered with thorns, the object would not be perceived to be an apple. The act of perception, there- fore, consists in the recognition of sundry attributes as like sundry attributes previously known, and as having relations to one another like the relations between the before-known attributes. This will appear still more clearly, when we recollect what takes place in visual perception. It is well known that the eye, unassisted by the muscular and tactual senses, can take no cognizance of distance, shape, or solidity —the only impressions which the retina receives are im- pressions of colour, and indirectly of superficial extension. It is because of this that infants reach out for the moon, and that blind men, on first receiving sight, are unable ' to distinguish between a round orange and a cubical block, without feeling the surfaces of the two. Only after re- peated and careful comparison of visual impressions with muscular ard tactual impressions is the patient enabled to discover, by the eye alone, that all the objects in the sod cH. Xv.] THE COMPOSITION OF MIND, 109 room or in the landscape are not in contact with his body ; and it is ouly after a similar elaborate comparison, that the young child achieves the feat of looking at an object in a given direction, or of recognizing by vision its father or mother, Accordingly, when looking about the room, all that you really see is a congeries of coloured spots. Your know- ledge of the presence of divers objects—chairs, windows, mir- ror, mantel-piece—is not given in the act of vision, but is the result of an exceedingly complex, though apparently instan- taneous, process of reasoning. Your seemingly immediate knowledge that a certain group of coloured spots means a chair is due to the fact, that from early infancy this group of coloured spots, or some other like group, has been associated with sun- dry impressions of touch and resistance, and with sensations yielded by the little muscles which turn the eye hither and thither. The frequency with which the association has been repeated has rendered the process of inference automatic, just as, to a less-marked extent, the process of reading, at first accompanied by a conscious classification of every letter, has become automatic, so that we are not aware of cognizing the letters at all. Nevertheless, although too rapid to rise into consciousness, the process is still one of inference, imply- ing, like any other process of inference, the grouping of cer- tain relations as like or unlike certain other relations. Cer- tain correlated groups of colours are automatically classified with other correlated groups of colours previously received upon the retina, and also with certain correlated groups of muscular and tactual impressions, previously received simul- taneously with the grours of colours in question. Thus our visual perception of objects consists ef a group of sensations plus a complicated series of inferences which does not differ fundamentally from a course of scientific demonstration. And the same truth may be, with equal justice, though less vividly, illustrated in the case of any other sense than sight. A much simpler ca.e than that of visual perception is that of a spoon, 110 COSMIC PHILOSOPHY. | [pr. 11. containing some unknown liquid, thrust into the mouth by another person in the dark. Here the only clue to the cha- racter of the liquid is its taste ; and when, by its peculiar mild pungency, the liquid is recognized as bromide of potassium, the psychical process consists of a gustatory sensation plus an act of classification by which the sensation is grouped with other like sensations previously received. The example is a good one, as showing us also the obverse case. If bromide of potassium has not been previously tasted, the result is simply gustatory sensation unattended by perception; or rather, it ig _ gustatory sensation generically classified as mildly pungent, but not specifically referred to any known liquid, and there- fore only partially interpreted. There is perception, but it is incomplete. It is not pretended that these psychological truths are established by the crude and fragmentary exposition here given. The numerous observations and experiments upon which they are based would be very interesting to recount ; but our space does not admit of detailed proof, nor is it needed ; since these truths are the common property of psy- shitopists, and will be questioned by no competent student of the phenomena of mind. Referring, for minute and elabo- rate proof, to Mr. Spencer’s “ Principles of Psychology,” let us be content with setting down the implication which is common to all these conclusions; namely, that between the various psychical processes thus far contemplated, which in- clade alike the measurement of celestial distances by the astronomer, and the direct perception of objects by the un- learned child, or indeed by the ape or dog, there is generic identity. The fundamental characteristic which is common to them all is the reception of certain groups of sensations, accompanied by the classification of these groups of sensa- tions, and of the relations between them, according to their various likenesses and unlikenesses. The difference between the highest and the lowest of the processes thus brought cH. Xv.] THE COMPOSITION OF MIND. 111 together consists solely in the heterogeneity and definiteness of the groups which are classified, and in the extent to which the classifications are compounded. To such a statement, however, there is one essential qualifi- cation to be added. It is not strictly correct to say that the classification involved alike in the most complex act of rea- soning and in the simplest act of perception is a classification of groups of sensations and of the relations between them. For, when an object is perceived, along with the sensations actually present, there are remembered or internally-revived sensations which enter into the classification, and these inter- nally-revived sensations are what we call ideas or images. For example, “ when passing the finger over a rough surface, the perception contains very much 14cre than the coordinated sensations immediately experienced. Along with these there go the remembered visual impressions produced by such a surface, which cannot be kept out of the mind, and in the suggestion of wnich the perception largely consists ; and there are automatic inferences respecting the texture and density of the substance.” So when we see an orange lying on the table, the only sensation actually present and entering into the case is the sensation of a patch of reddish-yellow colour surrounded by other unlike patches of colour. The other elements in the classification of which the perception consists are ideas or internally-revived sensations of position, shape, bulk, texture, juiciness, and so on. And now we discover another point of difference in degree between perception and .easoning. While in perception some of the elements classi- fied must be sensations actually present, in reasoning al] the elements classified may be ideas or internally-revived sensa- tions. The sides and angles of the isosceles triangles which the astronomer compares in estimating the moon’s distance are ideal sides and angles; and the naturalist, in writing about the classification of ruminants, deals solely with in- ternally-revived impressions of horns, hoofs, and multiple 112 COSMIC PHILOSOPHY, (PT. 1 stomachs, which were previously present to sense. Thus the classification involved in reasoning differs from that involved in perception, not only in heterogeneity and definiteness, but also in indirectness, Nevertheless the difference is not fundamental, but is only a difference in degree ; as is proved by the fact that alike in reasoning and in perception there is implied the previous reception of the actually present sensa- tions of which the ideas or revived sensations are the copies. Our statement, therefore, will become strictly correct if we say that the fundamental characteristic common to the most refined reasoning, and the crudest perception, is the presence of certain states of consciousness, accompanied by the classifi- cation of these states and of the relations between them according to their various likenesses and unlikenesses; the differences between the processes being differences in hetero- geneity, definiteness, indirectness, and extent of integration or compounding. Let us next observe that, as between the highest and lowest kinds of reasoning there is a great difference in the extent to which the comparison of relations is carried, so between the highest and lowest kinds of perception there is a similar difference. There is a striking contrast in degree of directness “ be- tween the perception that some surface touched by the finger is hard, and the perception that a building at which we are looking is a cathedral. The one piece of knowledge is almost immediate. The other is mediate in a double, a triple, a quadruple, and even in a still higher degree. It is mediate inasmuch as the solidity of that which causes the visual im- pression is inferential; mediate inasmuch as its position, its size, its shape, are inferential; mediate inasmuch as its xaterial, its hollowness, are inferential; mediate inasmuch as its ecclesiastical purpose is an inference from these irfer- ences; and mediate inasmuch as the identification of it as a particular cathedral is a still more remote inference resulting a ot S any CH, XV.] THE COMPOSITION OF MIND. 113 from the union of these inferences with those many others through which the locality is recognized.”* From this example it appears that while, at the highest extreme, perception emerges into reasoning, on the other hand at its lowest extreme, as where a body is perceived to be rough or hard, it borders very closely upon simple sensation. Pro- ceeding, then, a step farther in our descending analysis, we have to examine the character of the difference between per- ception and sensation. Sensation, uo less than perception, has a variety of grades. At the one extreme it rises to a point where it is barely dis- tinguishable from perception; at the other extreme it lapses into an unconscious or sub-conscious psychical state. While writing these lines the sum-total of my consciousness may contain elements contributed by dull sounds of persons walk- ing overhead, by the rumbling of wagons in the street, by faint odours wafted from the kitchen, by soothing pulses of sensation from the pipe held in my mouth, and by the occa- sional striking of the cuckoo-clock, as well as by the pressure exerted by the chair in which I am sitting, and the table upon which my arm is resting, and the pen which is grasped in my fingers. But, while I am absorbed in thought, none of these elements rise into the foreground of consciousness : though they are present as psychical states, as is shown by the fact that the going out of the pipe or the failure of the clock to strike is noticed, yet I become conscious of them, in the ordinary sense of the word, “ only when they pass a certain degree of intensity,’ as when a child overhead falls on the floor, or when the shriek and rumble of a passing rail- way-train are added to the confused mass of out-door noises ; “and only then can I be said to experience” these feelings “as sensations.” But when a psychical state rises into the foreground of consciousness an] becomes known as a sensa- tion, as when my finger happens to touch the heated pipe- 1 Spencer, Principles of Psychology, vol. ii. p. 245. VOL, II, T 114 COSMIC PHILOSOPHY. [er. 1 bow], then “Tnot only contemplate the affection as an affec- tion of myself—as a state through which my consciousness is passing or has passed—but I also contemplate it as exist- ing in a certain part of my body—as standing in certain relations of position, I perceive where it is.” The close relationship between sensation and perception is illustrated by this example: nevertheless psychology here distinguishes between two portions of the mental act. Though in the practical experience there is no separation between the two, yet analysis enables us to distinguish between the con- sciousness of the painful feeling and the consciousness of the presence of the heated object which causes the feeling ; and the former of these we call sensation, while the latter we call perception. We shall now be greatly assisted by observing a psycholo- gical fact of which Sir William Hamilton caught a glimpse, though, as usual, his analysis was not sufficiently thorough, and his statement of the case was inaccurate. We need not pause to criticize the theorem that while “perception proper and sensation proper exist only as they coexist, in the de- gree or intensity of their existence they are always found in an inverse ratio to each other;” for its inaccuracy has been fully demonstrated by Mr. Mill and also by Mr. Spencer, who shows the true statement to be, “ not that sensation and perception vary inversely, but that they exclude each other with degrees of stringency which vary inversely.” To illus- crate this, we will suppose that you are getting water from a hot-water faucet, and that, as the water begins by running cold, you clasp your hand about the faucet so as to turn it off when the water has become sufficiently warm. While the water is cool or tepid, sensation is at the minimum, and not only is there no exclusion of perception, but conscious- ness is occupied with the outer phenomena, the faucet and the running water, more than with the inner phenomenon, the feeling of temperature. The pointed end of the upright vE XxVv.] THE COMPOSITION OF MIND. 115 part of the faucet, and the protuberance where the horizontal piece is fitted upon it, awaken tactual sensations which co- exist with the sensation of temperature, and the automatic comparison of these sensations which constitutes the per- ception of the faucet goes on unhindered. To concentrate consciousness upon the feeling of temperature requires a voluntary act of attention, induced by the desire to know how warm the water is getting. As the water becomes very much warmer, so as to be slightly uncomfortable, the per- ception of the faucet does not become gradually less vivid, but it tends to disappear entirely, and conscivusness tends to occupy itself exclusively with the feeling of temperature. Only through a distinct voluntary effort can the perception be made to come into the foreground of consciousness. If, now, there comes a sudden spurt of very hot water, the tactual perception of the faucet is for the moment entirely excluded, and the perceptive act implied in the estimation of the degree of temperature is also expelled from conscious- ness, which is occupied entirely with the sensation of pain, inducing a violent withdrawal of the hand. Here sensation, reaching a maximum, has quite driven out the group of tactual perceptions, and even visual perceptions are to that extent held in abeyance, that for the moment they cease to occupy the attention. If, now, a piece of soap is taken from its dish, the newly-aroused group of sensations—of weight, hardness, smoothness, and the rest—exist in minimum in- tensity, and consciousness is occupied, not with them, but with the presence of the piece of soap: perception tends to exclude sensation. “What, now,” inquires Mr. Spencer, “is the real nature of this mutual exclusion? Is it not an instance of the general iact that consciousness cannot be in two equally distinct statics at the same time; and that in proportion as the pre- Jominance of one state becomes more marked, the suppres- sion of other states becomes more decided? I cannot know r:2 116 COSMIC PHILOSOPAY. (pr. 1 that I have a sensation without, for the moment, having my attention specially occupied with that sensation. I cannot know the external thing causing it, without, for the moment, having my attention specially occupied with that external thing. As either cognition rises, the other ceases.” By the “external thing,” Mr. Spencer does not here mean the Ding an sich, but the group of phenomena which are referred to an existence outside of the organism. But we have already seen that, when consciousness is so occupied with such a group of phenomena that the result is the perception of an object, the psychical act involved is an automatic classification of sundry states of consciousness and of the relations between them, according to their various likenesses and unlikenesses. Thus we arrive at the distinction between sensation and percep- tion. Impossible as it is to disentangle the two in practical experience, analysis yet distinguishes the former as an ap- parently elementary state of consciousness, while the latter is “a discerning of the relations between states of conscious- ness.” According, therefore, as attention is directed chiefly to a conscious feeling or to the relations between a number of feelings, is now sensation and then perception predominant. It remains to be observed that sensations, or—as we may otherwise call them—feelings, are either peripherally or cen- trally initiated. In other words, a feeling may either origi- nate at the surface of the organism—as is the case with sensations of sight, hearing, smell, taste, and touch, and in the main with muscular and thermal sensations; or it may originate in the interior of the organism—as is the case with the sensations of hunger and repletion, and with certain mus- cular sensations, such as cramp; or, aguin, it may start from some group of nerve-centres, as is the case with those vazue feelings which accompany more or less complex acts of per- ception and reasoning, and which, when they acquire a certain devree of prominence, we call emotions. By the inclusion of these states of consciousness, the term “feeling” covers a 1 ee rH, Xv.] THE COMPOSITION OF MIND. 117 somewhat wider range of meaning than the term “sensation.” Nevertheless the current use of the word “ feeling” to desig- nate indifferently a sensation or an emotion bears unconscious witness to the fact that the two kinds of psychical state differ only in their modes of genesis and of composition. The con- trast between a peripheral sensation, as of colour or touch, and an emotion, is chiefly a contrast in degree of definiteness and of localization. But this contrast holds also between _ peripheral sensations and such vague internal sensations as hunger, which, being known as cravings, are assimilated to the lowest orders of emotion. From this difference in defi- niteness arises the fact that the peripheral sensations admit of being definitely grouped according to their relations of likeness and unlikeness, and thus afford the material for per- ception and reasoning, while emotional states admit no such definite grouping, but arrange themselves variously in clusters, the particular character of the cluster being determined by certain contemporaneous perceptions or ideal reproductions of past perceptions. For these reasons the ultimate psycho- logical nature of emotion can be reached only through a syn- thetical interpretation which starts by recognizing the fact that, along with that classifying of conscious states which occurs in perception and reasoning, there goes on a recogni- tion of certain states as pleasurable or desirable to retain in consciousness, and a recognition of certain other states as painful or desirable to expel from consciousness. Thus in practical experience emotions are, in however slight a degree, inseparably associated with perceptions and inferences, as the vague, internally-initiated feelings accompanying the definite peripheral feelings in the classifying of which the perceptions and inferences consist. Looking back, now, over the region already traversed, we find that we have passed in review a large number of mental operations which differ immensely in complexity, some of them being performed only by the most highly-educated adult 118 COSMIC PHILOSOPHY. [pr. 11, civilized men, while others are performed habitually by children, barbarians, and numerous animals inferior to man. Yet, amid all this diversity, our analysis has detected a funda- mental unity. In spite of their vast differences in complexity, we have seen that all these mental operations are ultimately made up of the same psychical process. The grouping of the relations among feelings is the elementary act which is re- peated alike in each simple and direct act of perception, and in each complicated and indirect act of ratiocination. At the present stage of our analysis, therefore, the ultimate elements of mind would seem to be feelings and the relations between feelings. It remains to add that relations themselves must be secondary feelings due to the bringing together of primary feelings. We can know a relation only as some modification of conscicusness resulting from some combination of the feelings directly aroused in us by inner or outer agencies; and such modification of consciousness must be itself a kind of feeling. For further illustration let us briefly mention the different relations in the order of their decreasing complexity, that we may note the fundamental relation involved in them all. The most complex relations are those of similarity and dissimilarity, as exemplified when we recognize the kinship between a thorough bred race-horse and a Shetland pony, or the complicated divergences between a city and a village. Simpler relations are those of cointension and non-cointension, as when we perceive that two sounds are equal in degree of loudness, or that in grasping wood and in grasping marble the feelings of temperature are different in degree; of coexten- sion and non-coextension, as when two lines or two areas are seen to be equal or unequal; of coexistence and non-coexistence, as when the yellow-reddish light reflected by an orange is re- garded as accompanied by sweetness and juiciness, but not by viscidity ; of connature and non-connature, as when greater warmth is mentally assimilated to less warmth, but distin- guished from blueuess or roughness. Now, underlying all ee eae = Paes —— . cH. Xv.] THE COMPOSITION OF MIND. 119 these reiations, and all mental processes whatever, is the relation of likeness and unlikeness between primary states of consciousness, Given the power of recognizing two feelings or conscious states as like each other, and two other feelings or conscious states as unlike each other, and we have the primordial process in the manifold compounding of which all operations of intelligence consist. Let us now take into the account the universally-admitted fact that consciousness is rendered possible only by ceaseless change of state—that a uniform state of consciousness is in no respect different from complete unconsciousness, If our minds were to become spellbound, like the palace of the Sleeping Beauty, all our thoughts and feelings remaining fixed im statw quo, our con- scious existence would be practically at an end. For con- sciousness to exist at all, it is necessary that a given state » should be followed by a different state. But this is not all that is required. A succession of feelings, of which no two were alike, would not give rise to consciousness, since the re- cognition of any feeling implies its classification with some antecedent like feeling. Consciousness, therefore, “is not simply a succession of changes, but an orderly succession of changes—a succession of changes combined and arranged in special ways.” Thus we reach the law of the Composition of Mind. Since intelligence cannot arise or continue unless consciousness is continually passing from one state into a different state, it follows that there must be a continuous differentiation of states ; and again, since intelligence cannot arise or continue unless particular states of consciousness are continually known as like certain previous states, it follows that there must be a continuous éntegration of states. Alike in the most rudimentary perception and in the most deve- loped reasoning, the essential process is the separation of the unlike and the bringing together of the like. So that, “under its most general aspect, all mental action whatever is definable as the continuous differentiation and integration of 120 COSMIC PHILOSOPHY. [pr 1 states of consciousness,” and the kind of mental action is regarded as high or low, according to the greater or less extent to which the differentiation and integration are carried, The phenomena of conscious intelligence are thus seen to conform to the universal law of evolution; and we may further note that this conclusion is entirely in harmony with the definition of psychical life as the continuous adjustment of inner to outer relations. For clearly, when an intelligence is developing in the midst of a complex environment, the greater the number of subjective relations which are adjusted to objective relations, the greater wil] be the extent to which the differentiation and integration of conscious states will be carried. Here we may seem to have arrived at a satisfactory con- clusion of our analysis. But the lowest depths of the pro- blem yet remain to be sounded, as will be seen when we consider a superficial objection not unfrequently urged against the foregoing views. Alike in all the mental operations which have formed the subject-matter of our analysis, we have seen that the relations of likeness and unlikeness enter- ing into the case are classified with certain other relations of likeness and unlikeness previously cognized. The thought which determines the astronomer in calculating the moon’s distance, implies previous experience of triangles and of numerical relations, In the classification of a giraffe there is implied previous acquaintance with the complex relations of structure and function connoted by the terms ruminant, ungulate, monodelphian, mammal, vertebrate, and animal. The perception of an apple implies numerous antecedent experiences of colour, size, configuration, smoothness, odour, and taste. And in like manner, though we have provisionally defined a sensation as an “elementary state of conscious- ness,” yet we have also seen that, in order to become truly conscious of a sensation, we must know it, or, in other words, must classify it with some like sensation previously felt, hee ~~ ae CO ee es cH. Xv.] THK COMPOSITION OF MIND. 121 In short, we have seen that there can be no cognition, of whatever order, which is not a recognition, necessarily im- plying some previous combination of psychical states. How, then, it is asked, can there be any first cognition? How can intelligence ever begin at all, if the first and simplest intelligent act implies a reference to experiences which, in accordance with the theory, must have preceded any intel- ligent act ? Formidable as this objection may seem, and unanswerable as it would have been, if urged half a century ago, it has to-day no force whatever; and those who now deliberately urge it succeed only in betraying their entire lack of acquaint- ance with the progress which psychology has made since the times of Reid and Stewart. As long as psychological questions were settled simply by introspection—by observing what goes on in the consciousness of adult civilized man— the objection here cited must have seemed conclusive. But familiarity. with the conception of evolution has now led us to regard things in general, not as coming at once into fulness of being, but as gradually beginning to be; and in the case of the phenomena of intelligence, this view of the ques- tion is amply justified by experiments in objective psycho- logy presently to be mentioned. The conception of an absolutely first cognition, not determined by previous psy- chical states, rests upon a fallacy similar to that upon which rested the preformation theory in biology. Just as it was formerly held that the embryo started as a fully-developed organism, differing from an adult organism only in size, so the objection which we are now considering involves the hypothesis that the earliest cognitions of an infant are like tnose of an adult in point of definiteness, the only difference being in the quantity of them. The latter hypothesis is as contrary as the former to the Doctrine of Evolution, and it is quite as decidedly negatived by the observation of facts. For, let us observe what is implied by the acquiring of a 122 COSMIC PHILUSOPHY. ee a definite cognition by an infant. If the foregoing analysis be taken as correct, it is obvious that when any object, as an orange, is first presented to the mind of an infant, it cannot be perceived or identified as an orange. Before this intel- lectual feat can be achieved, there must go on for some time that complicated grouping of visual, tactual, and gustatory sensations above described. In accordance with the esta- blished theory of vision, we must admit that, when the orange is held before the child’s eye, the only sensation aroused is that of a reddish-yellow colour, which cannot even be perceived to be found until after it has been associated with sundry tactual sensations. But this is not all. Not even the sensation of a reddish-yellow colour can acquire definite shape in consciousness, until sensations of blue, or red, or green, or white colour, have been aroused, with which it can be contrasted, and until a subsequent like sensation of reddish-yellow colour has been aroused to which it can be assimilated. Observe, now, the position into which we are brought. We are obliged to hold that the first sensation of orange-colour cannot, strictly speaking, exist as a sensation at all; while, nevertheless, a subsequent sensation of orange- colour (not, in any actual case, the second, but the twentieth or hundredth) occurring after intervening sensations of blue or green, can acquire definite shape as a sensation by being compared with this first sensation which is not strictly a sensation. Obviously, then, though the first presentation of orange-colour cannot awaken a visual sensation which can be known as such, it must produce some psychical state which is real, though not known. For if no psychical state were produced by the first presentation, then the second, or twentieth, or hundredth presentation could no more awaken a definite state of consciousness than the first. We are thus led to the assertion that states of consciousness may be produced by the differential grouping or compounding of psychical states which are beneath consciousness. iv ; vy : a 4 * 4 a . f 4 a] ‘ i < eo > a9 CH. XV.] THE COMPOSITION OF MIND. 123 ‘Now, this conclusion, which admirably explains the begin- nings of conscious intelligence in the young child, is com- pletely confirmed by experiments lately made with reference to the continuous genesis of sensations in the adult. Not only does the infant frame its earliest conscious sensations by the compounding of unconscious or sub-conscious psy- chical changes, but in every sensation of sound, colon, odour, taste, or touch, which the adult receives, there is a precisely similar formation of a conscious state by the com- pounding of unconscious or sub-conscious psychical states, In the case of sound, the evidence for this statement amounts to complete demonstration; the evidence is hardly less strong in the case of sight; and, in the case of the other senses, all the evidence thus far obtained points toward the same conclusion. Let us first examine the composition of a sensation of sound, as admirably elucidated by M. Taine in - his recent treatise on “ Intelligence.” In musical sounds three characteristics are to be distin- guished—loudness, pitch, and quality or timbre. The first of these, the loudness, depends upon the amplitude of the atmospheric waves by which the sensation of sound is caused. A series of sound-producing waves, like any other series of waves, has its elevations and depressions, and the height of the elevation above the depression is called the amplitude of the wave. The loudness of the sound varies as the square of the wave’s amplitude. From this it follows that every elementary sound has a period of minimum intensity, answering to the wave’s minimum amplitude when it is just beginning to rise ; secondly, a period of maximum intensity anwering to the wave’s maximum amplitude when it las risen to its greatest height; and, thirdly, a period of mini- mum intensity, answering to the wave’s minimum amplitude when it has sunk nearly to the level again; while between shese minima and the maximum there are many varying jegrees of loudness. In other words, every elementary 124 : COSMIC PHILOSOPHY, [pr. IL sound is at first faint, then gradually becomes loud, then erows fainter, till it disappears. Now, note what happens when elementary sounds are made to succeed each other, If the succession be irregular, there is a mere chaos of noises—a case with which we need not here deal. But if the succession be regular, and steadily increase in rapidity, there follows a remarkable series of results, As long as the waves or pulses answering to the elementary sounds succeed each other slowly, the sounds are distinguishable from each other as raps or puffs, according to the instrument employed, and each has its maximum and its two minima of intensity. But, when the waves begin to strike the ear at the rate of about sixteen in a second, the consciousness of separate raps or puffs becomes evanescent, and there arises the conscious- ness of a continuous tone of very low pitch. That the con- sciousness of the separate sounds has not quite ceased, and that the continuousness of the tone which they compose is not complete, are shown by the fact that the maxima and minima are still perceived. In the deepest bass-notes of an organ, for example, the pulsations are clearly distinguishable —a fact which proves that we are conscious of the effects answering respectively to the protuberances and to the hollows of the waves. Now, the pitch of a tone depends upon the rapidity with which the waves succeed each other, and, therefore, upon their length, or the distance between two successive hollows, because as the waves come faster they grow shorter. The shorter the waves, the higher the pitch. Hence, as the pitch rises, the protuberance of any wave approaches nearer and nearer to the protuberances of the waves immediately behind it and in front of it, and the maximum intensities of sound which answer to the protuber- ances become crowded together in consciousness. The result is that, after a while, the maxima and minima are no longer distinguishable by the ear, so that by no effort of attention can we discern the elementary pulses of which the tone is eT CH. XV.] THE COMPOSITION OF MIND. 128 composed. ‘The tone asserts itself to be completely’ homo- ceneous. All that mere introspection could discover in consciousness would be an apparently simple sensation of musical tone. Yet into the composition of this sensation there enter a thousand or several thousand psychical states answering to the presence of as many elementary sounds with their maxima and minima of intensity. And if any one of these elementary sub-conscious psychical states were absent, the character of the conscious sensation would be different from what it is. But this is not all, Every musical tone has a timbre or quality of its own, according as it proceeds from a piano, a violin, a flute, or any other instrument. Now, Helmholtz has proved that the quality of any tone is due solely to the number and combinations of certain higher and fainter tones which accompany it. Along with the fundamental note there are heard sundry harmonic notes, due to vibrations from two to ten times more rapid than those which con- stitute the fundameutal note. When any note is sounded on the piano, the first six harmonics are sounded with it; when the same note is sounded on the violin, by means of the bow, the first six harmonics are sounded so feebly as to be overpowered by the seventh, eighth, ninth, and tenth; and this is the only cause of the difference in quality of tone between the piano and the violin. Now, by an effort of attention these harmonic over-tones may be recognized as distinct sensations when two or three notes are slowly struck. But in ordinarily rapid playing they are not dis- tinctly recognized. Their only effect is to impart to the tones that peculiar quality which enables the ear to re- cognize the instrument from which they emanate. Thus our apparently simple sensations of musical sound are enor- mously complex. When F-in-alé is sounded on the violin, there are produced, in the course of a single second, several thousand psychical states which together make up the sen- 126 COSMIC PHILOSOPHY. [pr. u. satiun of pitch, fifty-five times as many psychical states which together make up the sensation of quality, and an immense number of other psychical states which together make up the sensation of intensity. These psychical states are not, in any strict sense of the term, states of conscious- ness ; for, if they were to rise individually into conscious- ness, the result would be an immense multitude of sensa- tions, and not a single homogeneous sensation. There is no alternative, therefore, but to conclude that in this case a seemingly simple state of consciousness is in reality com- pounded of an immense multitude of sub-conscious psychical changes. Returning, now, to what we have called the elementary sound, by the manifold compounding of which all cognizable tones, qualities, and intensities are built up, we shall the more readily yield to the evidence which shows that even this primitive unit of sound is not elementary. For, as M. Taine observes, each so-called elementary sound, in passing from its minimum to its maximum, passes through an infinite series of degrees of intensity, and, unless there were some psychical modification corresponding to each increment of intensity, there would be no state of consciousness answer- ing to the total rise from the minimum to the maximum. Again, while, for simplicity’s sake, we have assumed that each of the raps or puffs which occur too slowly to be heard as a single tone of lowest pitch is heard by itself as an ele- mentary sensation, this is not strictly true. For the so- called simple sensation must be either a sensation of musical tone or a sensation of noise. In the former case its composite character has been already shown. In the latter case, in the sensation of noise, rap, or puff, the truly primitive elements are sub-conscious psychical states answering to successive waves of unequal lengths. Any one of these waves by itself will not produce a genuine state of consciousness ; it is only by compounding the sub-conscious psychical affections which “4 en. xv.] THE COMPOSITION OF MIND. 127 they severally produce, that we obtain the so-called elemen- tary sensation of noise or rap. In every way, therefore, the conclusion is forced upon us that every one of our apparently simple auditory sensations is made up of a vast multitude of psychical affections, of which the really simple ones would never rise into con- sciousness save by being joined with others. Our simplest cognizable sensation of sound is in reality a compound of the fourth or fifth, or even of some higher, order. In the case of visual sensations, the same conclusion is reached by a precisely similar argument, sensations of colour differing from those of sound only as answering to wave- lengths immeasurably shorter and more rapid in succession. It is unnecessary to insist upon the manifold analogies be- tween sound and light, which are each day brought more vividly before the attention of the physical inquirer, as, for example, in the wonderful but plausible hypothesis lately pro- pounded, that all the lines in the spectrum are simply the harmonic overtones of a fundamental colour, which, being a couple of octaves below red, is itself invisible. Restricting our statement to ascertained points of resemblance, it may be said that the argument from the phenomena of musical pitch applies step by step to the phenomcna of colour as we rise in the scale from red to violet; the only difference being that, as the slowest vibrations which the eye receives occur at the rate of about 458,000,000,000,000 in a second, we cannot experimentally distinguish, as in the case of the lowest sounds, the seemingly elementary sensation which answers to each couple of vibrations, Nevertheless, from experiments with the electric spark it has been shown that a sensation of light which endures for one second is composed of at least a million successive sensations, each one of which, if sepa- rately excited, would rise into consciousness and be recog- nized as a flash of light. Now, as this flash of electric light is cojnized as white, it follows that the cognizable sensavion 128 COSMIC PHILOSOPHY, (pr. m1, which lasts for one-millionth of a second is really made up of at least three sub-conscious psychical states, which, if they were severally to rise into consciousness, would be severally cognized as red, green, and violet flashes—these being the primitive elements of which the consciousness of white light is composed, This fact alone shows that the method by which a sensation is formed out of sub-conscious psychical changes is essentially the same in the eye and in the ear. No such elaborate investigations have been made with re- ference to the other peripheral sensations. Yet, in the cases of smell and taste, the argument is not essentially different from what it is in the cases of hearing and vision. The physical antecedent, either of smell or taste, is a chemical reaction between particles of the odorous or sapid substance, and the ends of the olfactory or gustatory nerve-fibrils. Now, a chemical reaction implies an enormous number of undu- latory movements by which myriads of molecules are seeking to reach a position of equilibrium. Accordingly, the end of the nerve-fibrils in the olfactory chamber or in the tongue must be rapidly smitten by little molecular waves, just as the auditory filaments are smitten by atmospheric waves; and thus there is indicated a course of argument similar to that employed in the case of sound. It may be fairly argued that if each wave does not produce some sub-conscious psychical effect, the sum of the waves will not produce a state of consciousness known as smell or taste; so that here too the seemingly primitive sensation is really derivative and _ compound. M. Taine’s argument with reference to the tactile sensa- tions is singularly beautiful, but no room is left for more than the briefest allusion to a few of its salient points. Ali tactile sensations are either dermal or muscular; that is, they are due, either to disturbances of nerve-fibrils embedded in the skin, or to disturbances of nerve-fibrils embedded in the extremities of the muscles lying under'the skin. In the first case, the sensa- on, xv] THE COMPOSITION OF MIND. 129 tion is either of contact or of temperature; in the second case, there is a sensation of resistance or pressure; and in both cases, when the sensation proper to the nerve is prolonged or intensified beyond a certain degree, it is at first accompanied and finaily supplanted by a sensation of pain. Now, Weber's experiments have shown that these differences in sensation are not due to the excitation of distinct nerves, but to the differently-combined excitation of the filaments of the same nerves. ‘The difference between the sensation of contact and the sensation of temperature depends upon the order.in which the filaments of a particular nerve are set in vibration. And thus, as Fick observes, we may understand why it is difficult to distinguish between a prick from a needle and a minute burn from a spark of fire; for the nearer we approach toa truly elementary sensation, the more evanescent becomes the distinction between the compound sensation of temperature and that of mechanical contact. On the contrary, when a larger area of skin is suddenly rubbed or burnt, so that enough nerves are brought into play to compound the elements of the sensa- tions, then there is no difficulty in distinguishing the feeling of temperature from that of mechanical contact. From these and many other kindred facts, to which scanty justice is done by this cursory allusion, M. Taine very plausibly concludes that our ordinary tactile sensations are made up of little component psychical affections differing only in number, order, and duration; while, according as these elementary psychical states are differently compounded, they form con- scious sensations which, as presented to consciousness, seem to be severally simple and distinct in kind. Throughout this remarkabie analysis questions are sug- gested which can be completely answered only when physics and chemistry, as well as physiology and psychology, are much more advanced than at present. Yet there are three important principles which we may regard as established in the case of sound, and as clearly indicated in the case of the VOL. II, K i130 COSMIC PHILOSOPHY. [PT. It. other sensations. The /irst is, that sensations which are apparently simple and elementary, and which cannot be analyzed by mere observation of consciousness, are neverthe- less compounded of many successive and simultaneous sensa- tions, which are themselves compounded of still lower psychical affections. The second is, that two sensations, which differ only in the mode in which their elements are compounded, may appear in consciousness as generically different and irreducible to each other. The third is, that two or more psychical affections which, taken separately, are as non-existent to consciousness, may, nevertheless, when ~ taken together, coalesce into’a sensation which is present to consciousness. And when these three conclusions are pre- sented in a single statement, they become equivalent to the conclusion above obtained from examining the beginnings of conscious int :lligence in an infant; namely, that states of consciousness may be produced by the differential grouping or compounding of psychical states which are beneath consciousness, This result is in entire harmony with what might be in- ferred @ priori from the known characteristics of nerve- action. Whether in the grey substance of ganglia, or in the white substance of nerve-fibres, the physical action which accompanies psychical changes is an undulatory displace- ment of molecules resulting in myriads of little waves or pulses of movement. From this fact we might have suspected that, as a cognizable state of consciousness is attended by the transmission of 2 number of little waves from one nerve-cell to another, so the ultimate psychical eleinents of each conscious state must correspond to the passige of these little waves taken one by one. And this infereuce, which by itself would be only a plausible guess, is raised to the rank of a scientific hypothesis by its harmony - with the results of the analysis above sketched. Thus we are led to infer, as the ultimate unit of which a ee ee a ee ee cu. Xv.] THE COMPOSITION OF MIND. 131 Mind is composed, a simple psychical shock, answering to that simple physical pulsation which is the ultimate unit of nervous action. By the manifold and diverse compounding of myriads of such primitive psychical shocks, according to the slight structural differences of different nerves, are formed innumerable elementary sensations, which appear to be generically different; just as aquafortis and laughing- gas, which seem generically different, yet differ really only in the proportions of nitrogen and oxygen which compose them. By a similar differential compounding of these elementary sensations, we get complex sensations of blue- ness and redness, warmth, pressure, sweetness, roughness, and of various kinds of timbre and degrees of pitch. Carry- ing still farther the same process of differentiation and inte- gration, we rise step by step to perceptions of greater and greater complexity, to conscious classifications, and to rea- soning in its various forms, from the crude inferences of the child, barbarian, or boor, to the subtle and indirect combina- tions of the artist and the scientific discoverer. Thus, amid all their endless diversities, we discern, though dimly, a fundamental unity of composition throughout all orders of psychical activity, from the highest to the lowest. Near the close of his first edition of the “ Origin of Species,” Mr. Darwin predicted that the establishment of his theory would eventually place the science of psychology upon a new basis—that of the acquirement of each mental faculty by slow gradations” We seem now to have fairly started upon the path which leads to this desired goal. For, while, among the mental operations above analyzed, some are peculiar to the highest human intelligence, there are others which are shared by the highest and the lowest human 1 Mr. Darwin has since recognized that this new basis is already well laid by Mr. Spencer. See Origin of Species, 6th edit., p. 428. Indeed the “Principles of Psychology,” upon which the present chapter is almost entirely founded, was first published in 1855, four years before the “Origin of Species.” L 2 132 COSMIC PHILOSOPHY. (pr. 1. intelligence, Others—as the simplest inferences, several complex perceptions, and all the most simple ones—are shared by all human intelligence with the intelligence of apes, dogs, horses, and indeed of the majority of mammals, many birds, and possibly some lower animals. Others, again —as the simplest perceptive acts implied in recognizing a sensation—must be shared with all those animals whose nervous system is sufficiently complex to allow of their having any consciousness whatever. While others, finally —as the simplest sub-conscious groupings of primitive psychical shocks—must be shared by humanity with all — those forms of animal existence which possess any nervous structure whatever. For instance, that reflex action which — occurs when the foot of a sleeping person, casually moved into a cold part of the bed, is quickly withdrawn without ~ arousing any state of consciousness, involves the activity of a fragment of the human nervous system which corresponds in general structure to the entire nervous systein of a medusa or jelly-fish. In such lowly creatures, then, we must sup- pose that the psychical actions which go on are similar to our own sub-conscious psychical actions, And, clearly, if we could trace the slow increments by which the nervous system has grown in heterogeneity, definiteness, and co- herence, during the countless ages which have witnessed the progress from the primeval marine vertebrate to the civilized modern man, we should also be able to trace the myriad stages of the composition of mind, from the reflex contrac- tions of a rudimentary fin, up to the generalizations of an Aristotle or a Newton. ~~ oS ee a ee ee eee ~ Pea Set See Se 2 i “Ue CHAPTER XVL THE EVOLUTION OF MIND. THaT the amcunt of intelligence manifested by any vertebrate animal depends to a certain extent upon the amount of nerve- tissue integrated in its cephalic ganglia, and especially in the cerebrum, is a truth familiar to everyone, though often crudely stated and incorrectly interpreted. In the lowest vertebrate, the amphioxus, there is no brain at all. In fishes, the cere- brum and cerebellum are much smaller tha. the optic lobes ; the cerebrum being in many large fishes about the size of a pea, though in the shark it reaches the size of a plum. Con- tinuing to grow by the addition of concentric layers at the surface, the cerebrum becomes somewhat larger in birds and in the lower mammals. It gradually covers up the optic lobes, and extends backwards as we pass to higher namma- lian forms, until in the anthropoid apes and in man it covers the whole upper surface of the cerebellum. In these highest animals it begins also to extend forwards. In the chimpanzee and gorilla the anterior portion of the cerebrum is larger than in inferior mammals; but in these animals, as in the lowest races of men, the frontal extension is but slight, and the fore- head is both low and narrow. In civilized man, the anterior portion of the cerebrum is greatly extended both vertically and laterally. As already observed, the most prominent physiological feature of human progress has been the growth xf the cerebrum. The cranial capacity of an averag Euro- 134 COSMIC PHILOSOPITY. [pr 1. pean exceeds that of the Australians and Bushmen by nearly forty cubic inches ; and the expansion is chiefly in tlie upper and anterior portions. But this parallelism between increased intelligence and increased size of the cerebrum is complicated by a further parallelism between the amount of intelligence and the irregular creasing and furrowing of the cerebral surface. In the higher mammals both the cerebrum and the cerebellum are convoluted. But the convolutions do not correspond with any “bumps,” real or imaginary, on the external surface of the skull; they are not symmetrical on opposite sides, like © the fancied “ organs” of the phrenologists ; nor indeed, so far as the general brain-surface is concerned, do they constitute elevations and depressions at all. The surface of the brain does not resemble a group of hills and valleys, but rather a perfectly smooth table-land cut here and there by very steep and narrow chasms. A perfectly smooth lump of butter, irregularly furrowed by a sharp knife held perpendicularly, would present a surface like that of the human brain. Now the amount of intelligence depends in some way on the number and irregularity of these furrows. In the lowest moncdelphian mammals, as the rodents and the lowest monkeys, there are no furrows, or only a few very shallow ones. In the carnivora and ungulata, there aré-numerous furrows, some of tkem tolerably deep, but all of them symmetr.cally arranged. As we proceed to the higher apes, we find the furrows increasing in number and depth, though not yet losing their symmetry of arrangement. Idiots, young children, and adult savages have these creases few and regular; and in the lower races their arrangement is similar in different individuals. But in civilized man the creases are very numerous, deep and irregular; and they are not alike in any two individuals,! 1 Phrenologists have done good service by familiarizing the unlearned public with the fact that the quantity of mental capacity is related to the ee ee ee ee ee ee ee CH. xvi] THE ZVOLUTION OF MIND. 135 The convolutions into which the human brain is divided by these furrows, consist for the most part of “eight distinct and concentric layers, formed chiefly of closely-packed fibres, and of crowds of cells of very different shapes, the layers differing in the relative proportion of cells and fibres, and in the manner of their arrangement.”! Each cell sends forth processes with which the tissue of certain fibres becomes continuous. The office of the fibres is to establish communi- cation between the cells. Between millions of these cells there run millions of fibres, establishing communications in all directions. And the elaborate researches of Schroeder van der Kolk have gone far to prove that thé shapes of the cells and the intricacy of their communications vary with the amount of intelligence. In various forms of mental disease, both cells and fibres undergo pathological changes, such as atrophy, hardening, softening, or some other form of degeneration. That is to say, not only are the activities of the cells impeded, but the channels of communication are variously obliterated or blocked up. quantity of brain. But the character of this relationship is seriously mis- interpreted both by phrenologists and by the rest of the unlearned public. It is impossible to say that a mun with an unusually large head must be a man of unusual mental capacity, because the quantity of mental capacity depends on many other factors besides quantity of brain. It not only depends upon the sinuons creasing of the brain-surface here described, which can in nowise Je eletected by an examination of the outside of the head, but it also depends largely, as Mr. Lewes well reminds us, upon the very im- portant clement of vascular irrigation. “ Many individual variatious in mental character depend on the variations in the calibre of the cerebral and carotid trunks—and many variations in the intellectual, emotive, and active tendencies depend on the relative importance of the cerebral and carotid trinks. The energy of the brain depends mainly on the calibre of its arteries ; the special directions of that energy depend on the territorial dis- tribution.” —Problems of Life and Mind, vol.i. p.151. Again, the quantity of available mental energy which can be evolved in a given period of time, depends, to a very great extent, upon the efficiency with which the blood is supplied with oxygen and freed from carbonic acid ; so that mental capacity not only depends upon capacity of brain, but also apon capacity of lungs and liver. In short, a thorough examination shows that while Mind is most directly correlated with Brain, it is indirectly but closely correlated with the entire organism. So that the attempt to estimate individual differences im mental capacity by referring to brain-size alone, is an utter absurdity. 1 Maudsley, Physiology and Pathology of Mind, p-: 55. 136 COSMIC PHILOSOPHY. (er. 0. Between these fibres and cells there are differences of mole- cular structure implying differences in molecular activity, While the matter composing a cell is built up in enormously complex ageregates of molecules, wholly unshielded from external disturbance, the nerve-matter of a fibre is protected throughout its entire length by a membranous sheath. And while it is probable that the action going on in a cell consists in the continual fall cf unstably arranged molecules into a state cf more stable equilibrium, from which a fresh rush of blood is continually raising tliem to their former unstable state ; it is probable that the action going on in a fibre consists in the successive isomeric transformations and retransformations of the systems of molecules which make up the fibre. These conclusions are quite probable, though not proven. But it is entirely proved that a cell is a place where nervous energy is liberated, while a fibre is a path along which nervous energy is transmitted. _ Bearing all this in mind, it appears that the cerebrum and cerebellum are places where countless centres are constantly liberating nervous energy, and where this liberated energy is continually flowing along definite channels and from one centre to another. But to make the statement complete, we should add that much of the liberated energy is drafted off along centrifugal fibres into the corpora striata, whence it flows into the meduila and spinal centres, and is thus diffused over the body. Omitting the further consideration of these circum- stances, let us inquire into the meaning of this unceasing interchange of molecular motion between the innumerable cells crowded together in the cerebrum and cerebellum. Ia other words, what are the functions of these supreme ganglia? That their functions are not in any degree the direct co- ordination of sensations and movements, would appear from the fact that these direct coordinations are already made in | the spinal cord and in the medulla. All the muscular adjust- CH. XvI.] THE EVOLUTION OF MIND. 137 ments made in the trunk and limbs are effected either directly by the spinal centres, or indirectly by the sympa- thetic ganglia in cooperation with the spinal centres. The medulla coordinates all these muscular adjustments with the museular adjustments uf the face, and with the impressions received from the speciulized organs of sense. It is therefore highly imprebable that the supreme ganglia can be in any way directly concerned with these coordinations. And the improbability is increased by the fact that the cerebrum and cerebellum are as destitute of sensation as the free ends of the finger-nails. Scratch one of the spinal centres, and the result is tetanus. Scratch the medulla, and the whole body is thrown into terrible convulsions. But the cerebrum and cerebellum may be scratched and sliced without pain or con- vulsion. They take heed only of those impressions which are communicated to them indirectly. Countless multitudes of nerve-fibres coming up from the medulla, are gathered together in the corpora striata; whence other fibres, con- tinuing from them, radiate to the innumerable cells of which the supreme ganglia are composed, We must conclude, therefore, that the functions of the cerebrum and cerebellum are comprised in the further com- pounding of sensory impressions already compounded in the medulla. And as such compounding involves the repro- duction of impressions received in lower centres, and also involves the coordination of past with present impressions, we may say that the supreme ganglia are the seats of the higher psychical life,—of memory, reason, emotion, and voli- ton. Dr. Maudsley has thus appropriately termed them the tdvational centres. But between the functions of the two, thus closely related, there is nevertheless a difference, Although the precise determination of the way in which ideational functions are shared between the two centres, has long remained a puzzling problem, there is good reason for ‘believing that Mr, Spencer has solved the difficulty by 138 COSMIC PHILOSOPHY. (pr. 1 assioniag to the cerebellum the office of doubly-compour d coordination in space, and to the cerebrum the otfice of doubly-compound coordination in time. The facts of com- parative anatomy, and of comparative psychology, so far as nown, are in harmony with this opinion. We saw in the chapter on Life and Mind that the extension of the cor- resnondence in time at first goes on parallel with the exten- sion of the correspondence in space; the increased area over which the organism can act being the measure of its in- creased capacity for adapting its actions to longer and longer sequences in the environment. But we saw also that in the human race the extension of the correspondence in time has gone on far more rapidly than the extension in space; the most striking characteristic of intellectual progress being the ability of civilized man to adapt his inferences and actions to remote contingencies. Side by side with these facts, comparative anatomy shows us that the cerebrum and cere- bellum at first keep pace with each other in growth; but, as we reach those higher mammals which exhibit some degree of foresight, we find the cerebrum outgrowing the cerebellum and overlapping it; while in man the growth of the cerebrum has been so great as to render comparatively insignificant all other changes in the nervous system. With the enormous cerebrum of civilized man we may further contrast the preponderant cerebellum in those carnivorous birds whose psychical life consists chiefly in the coordination of those extremely complex and remote space-relations in- volved in the swooping upon prey from great distances. The human cerebellum is absolutely larger than that of such birds; but its smallness relatively to the cerebrum is a fact parallel with the simplicity of the space-relations which man coordinates, as compared with the time-relations, Among the latter are comprised all our ideas of cause, motion, progress,—in a word, all manifestations of force which involve the relation of scquence. But these ideas a ee en aan ee ~ ee a ee eae eee ae CH. Xv1.] THE EVOLUTION OF MIND. 139 make up by far the largest and most heterogeneous portion oi our psychical life. I am inclined to regard thes. considerations as very powerful ones,—and there are several others which lead to the same conclusion. To present the case properly would require a whole chapter ; but it is not essential for our present purpose that the question should be decided. Whether Mr. Spencer’s view of tne respective functions of the cere- brum and cerebellum be correct or not, it equally remains true that the class of functions shared by the two are idea- tional functions. They compound in double, triple, quad- ruple, or in far higher multiples, the sensory elements already simply compounded by the medulla. And it is in this com- pound grouping of impressions, past and present, according to their various degrees of likeness and unlikeness, that thought and emotion, the highest phases of psychical life, consist. A moment ago we asked, what is the meaning of the seaseless interchange of molecular motion which goes on among the innumerable cells of the brain? We now see what is the meaning of it, for there can be but one meaning. The continual redistribution of nervous energy among the cells, is the objective side of the process of which the sub- jective side is the recompounding of impressions. If we may for a moment unduly simplify the matter, it may be said that for every renewed grouping of impressions, for every revived association of ideas, there is a nervous dis- charge between two or more cells, along formerly-used sets of transit-fibres ; and for every fresh grouping of impressions, for every new connection of ideas, there is a discharge along new transit lines. In reality the matter cannot be so simple ns this, since, as we shall presently see, the maintenance of consciousness implies a state of tension between many simul- taneous discharges. But however great the complexity, the principle remains the same. 140 COSMIC PHILOSOPHY, [PT. 11 If it be objected to this view that it obliges us to assume a vast amount of differentiation and integration in the brain, duiing the lifetime of single individuals, it may be replied that the assumption is fully sustained, both by sound deduc- tion and by observation. Not only does the brain increase in size and heterogeneity during the first twenty-five years of life, but ordinarily it increases in heterogeneity, and often in size, for many years later; and in some cases it increases in heterogeneity until the end of life. The brain of a young child is in homogeneity like the brain of an ape; the furrows are shallow, symmetrical, and few in number. With advanc- ing years they increase in number, depth, and irregularity ; and the increase is most marked in those persons who do the most brain-work. In the brains of five very eminent men examined by Wagner, the heterogeneity of surface is described as quite astonishing. Such facts prove that the operations of thought work strongly-marked structural changes in individual brains, in the course of a few years. And as these strongly-marked changes are but the summing- up of countless little changes in the arrangements of cells and fibres, the inference is inevitable that such little changes must be going on all the time. This is the testimony of observation, and deduction might have taught us to expect as much; since the molecules of nerve-tissue are chemically by far the most unstable molecules known to science, ever ready to undergo metamorphosis and arrange themselves in new groups. Waste and repair go on more rapidly in the brain than in any other part of the body; the cerebrum, weighing between three and four pounds, receives at each pulsation one-fifth of all the blood sent from the heart, and if the supply is stopped for an instant, consciousness ceases. Where nutritive change is so excessively rapid, such structural changes as are involved in the continual setting-up of new transit-lines, must be readily effected. And quite in harmony with this course of inference is the fact that, when cerebral cH. XVI.] THE EVOLUTION OF MIND. 141 nutrition is notably retarded, as by the anemia and feeble circulation of disease or old age, new associations of ideas become difficult or even impossible. To sum up this whole preliminary argument: ng cerebrum and cerebellum are organs whose function is ideation or the generation of ideal feelings and thoughts, They are organs made up of a tissue in which chemical changes occur with unparalleled rapidity. We cannot see these changes go on, but we can equally well infer their seneral character when we have examined the chemical properties and molecular structure of the tissue in which they occur. Microscopic and chemical examination of this tissue shows that these chemical changes must consist in a perpetual transfer of energy from one cell to another along transit-lines composed of nerve-threads. Bear in mind that the cell does not average more than one ten-thousandth of an inch in diameter, and that the quantity of matter con- tained in a transit-line is almost infinitely small. Now since the cerebrum and cerebellum are, subjectively speaking, places where ideation is continually going on; and since they are, objectively speaking, places where nerve-cells are con- tinually sending undulations back and forth along transit- lines; the inference seems forced upon us, that the transfer of an undulation from one cell to another is the objective accompaniment of each subjective unit of feeling of which thoughts and emotions are made up. And if this be so, it becomes a mere truism to say that the formation of a new association involves the establishment of a new transit-line, wr set of transit-lines, while the revival of an old association involves merely the recurrence of motion along old transit- lines. That this is merely a hypothesis, I readily grant, Nevertheless it is a verifiable hypothesis ; it is in harmony with all that we know of nerve-action ; and it may be held provisionally until some better one is propounded. When we proceed to see how many phenomena it explains, we shall 142 COSMIC PHILOSOPHY. [pr. 11. he, I think, quite ready to admit that, if it does not contain the whole truth, it must at least contain a foreshadowing of the truth. For we have now to note that, by a deduction from an established law of molecular motion, this hypothetical law of nervous action can be shown to ex lain that law of association which subjective analysis proclaims as the fundamental law of intelligence. In the chapter on Life and Mind, we saw that the chief business of psychology is to answer the question how there comes to be established in the mind a relation between two subjective states x and y, answering to a relation between two phenomena A and B in the environment. How is it that there is a subjective rela- tion between the idea of sweetness and the group of ideas comprised in the visual perception of a peach, answering in some way to the objective relation between the coexistent properties of the peach, so that the presentation of the one to the cephalic ganglia is inevitably accompanied by the representation of the other? This question lies at the bottom of psychology, and we have now to see how it is to be answered. The answer will lead us throngh a portion of the domain of molecular physics, and will incidentally give us a hint concerning the genesis of nervous systems. In the chapter on Matter, Motion, and Force, it was shown that all motion takes place along the line of least resistance, whether the motion be the movement of a mass of matter through a resisting medium, or the passage of a series of undulations through the molecules of an aggregate. Let us reconsider this truth in one of its concrete applications. When a wave of molecular motion traverses a mass of matter for the first time, the line of least resistance will of course be determined by the intimate structure of the mass. But now mark what happens. Immediately after the passage of the wave, the intimate structure of the mass, in the vicinity of the line along which the wave has travelled, is pH. XVI.] THE WVOLUTION OF MIND. 143 different from what it was a moment ago. The passage of the wave has pushed a linear series of molecules out of position, and a short time must elapse before these molecules can return to their positions. Therefore if the first wave is instantly followed by a second, starting from the same point, the line already traversed will be the line of least resistance, even more decidedly than before. The second wave will encounter less resistance than the first wave, because it will find its work of altering the positions of the molecules already partly done for it. Thus, according to the molecular mobility of the matter in question, the transit of succeeding waves, along the line once established, will rapidly become less and less hindered. And the process must go on either until the inertia of the molecules along the transit-line opposes a Minimum of resistance to the passage of the wave, or even until the energy given out by the molecules in changing position adds to the momentum of the wave. In either case there is established a permanent line of least re- sistance, along which all subsequent waves that start from the same point must travel. The most familiar illustration of this process is afforded by the facts of magnetization, which show “that the establishment of undulations along certain lines determines their continuance along those lines.”? The case of liquid matter flowing through solid matter—as when currents of rain-water, percolating through loose soil, gradually break away obstructing particles and excavate small channels which ultimately widen and deepen into river-beds—is a case isi which similar dynamic principles are involved. In all these cases, “if we confine our attention to that part of the motion which escaping transformation continues its course, 1 An illustration of this principle is perhaps to be found in the mellowing of old violins. According to Prof. Tyndall, “the very act of playing has a beneficial influence; apparently constraining the molecules of the wood, which in the first instance were refractory, to conform at last to tle require- ments of the vibrating strings.” On Sound, p. 90. As Dr. Maudsley would tay, “musical residua” remain in the molecular structure of the wood, 144 COSMIC PHILOSOPHY. [er. 11 then it is a corollary from the persistence of forve that as much of this remaining motion as is taken up in changing the positions of the units, must leave these by so much less able to obstruct subsequent motion in the same direction.”? Now in the case of organic bodies, the enormously complex molecular changes involved in nutrition are such as to aid in the setting-up of the most perfect transit-lines. In an inorganic mass the molecules have comparatively little mobility, and they do not leave their connections from — moment to moment, to be instantly replaced by new molecules. But the complex clusters of molecules which make up living tissue possess immense mobility, and they are continually falling to pieces and getting built up again. Consequently | the repeated passage of waves either of fluid matter or of molecular motion along a definite iine of least resistance, not only changes the positions of the molecular clusters, but also modifies the nutritive changes by which the temporary — equilibrium of the clusters is restored. Instead of a set of relatively homogeneous molecules, which are simply pushed aside and then tend to oscillate back again, the advancing wave encounters a heterogeneous edifice of molecules, which tumbles to pieces and is instantly rebuilt. But in the re- building the force exerted by the advancing wave has to be expended ; and the result is that in the rebuilt cluster there - is a surplus tension exerted in the very direction in which the waves are travelling. The transit-lines thus become far more permeable than any which can be established in in- organic bodies. The energy given out by the decomposing cluster of molecules adds to the momentum of the wave; so that the line of least resistance becomes to a certain extent a 1 Spencer, First Principl:s, p. 248. Thus, though Mr. Mill is justified in saying (Inaugural Discourse, p. 62) that “physiology is the first science in which we [distinetly] recognize the influence of habit—the tendency of some- thing to happen again merely because it has happened before”—yet, as we here see, the phenomena of habit are foreshadowed in the inorganic world, An admirable instance of that continuity among phenomena whic): is every. where implied by the theory of evolution. cH. XvI.] THE EVOLUTION OF MIND. 145 line of traction. A good illustration is afforded by the gradual evolution of the circulatory system as we ascend in the animal scale. In the lowest animals which possess any nutritive fluid perceptibly distinct from the protoplasmic jelly of which their bodies are composed, this*fluid percolates here and there at seeming random, its course being determined by local pressures, just as in the case of rain-water trickling through the ground. Now as we ascend to higher animals, we find that the nutritive fluid has wrought for itself certain channels, to which it confines itself, and which gradually become more and more definite in direction, and more and more clearly demarcated from the adjacent portions of tissue. Until, when we reach animals of a high type of structure, we find the blood coursing through permanent channels, the walls of which contract and expand in such a way as to assist the blood in its progress. A similar explanation is to be given of the genesis of the contractile fibres of muscle, as due to the continuance of molecular undulations along certain lines. When we come to the nervous system, we find most com- pletely realized all the conditions requisite for the rapid establishment of permanent transit-lines. The clusters of molecules of which wnerve-tissue is composed, are more heterogeneously compounded than any other known systems of molecules; and the alternate pulling to pieces and put- ting together of these clusters, which we ca!l nutrition, goes on here with unparalleled rapidity. Of all known sub- stances, nerve is the most changeable, the most impressible, the most readily adaptable to changing combinations of -neident forces,—in short, the most easily differentiable and integrable. Hence we find that those long transit-lines, Known as afferent and efferent nerves, are not ouly so con- stituted that a wave of disturbance set up at one end is immensely increased before it reaches the other end, but. are also protected by enveloping clusters of molecules in such a VOL, IL, L 146 COSMIC PHILOSOPHY, [Pr. 11. way that none of the transmitted motion is allowed to escape laterally. Ease of transit is here witnessed at its maximum. : Making use of these theorems of transcendental physics, and applying t6 the problem his vast and accurate know- ledge of biological details, Mr. Spencer has propounded a theory of tle genesis of nervous systems of all orders of complexity, which, whether entirely or only partially true, must be regarded as one of his most brilliant achievements. In the lately-published “ Physical Synthesis,” which con- cludes the first volume of his “ Principles of Psychology,” Mr. Spencer shows that the irritability which characterizes the entire surface of the lowest animals, and which probably consists in the isomeric transformation of colloidal clusters of molecules distributed over the surface, must gradually be- come concentrated in certain definite transit-lines, just as the circulation of a nu ritive fluid becomes confined to certain channels : while the collision of waves which takes place wherever two or more of these transit-fibres inosculate, must result in such chemical changes, and in the gradual formation of such a structure, as characterize nerve-centres, But the exposition, when carried into details, is altogether too abstruse to be profitably presented here, nor is it neces- sary for our present purpose. The explanation of the laws of association only requires that, starting with some kind of nervous system as already established, we should examine the character of the nutritive changes set up within it by environing agencies. | The foregoing argument shows us that the most prominent characteristic of such changes is the formation of transit- lines between neighbouring cells; and we have seen that the more frequently a wave of molecular disturbance passes along any such transit-line, the more easily will it pass, and the more difficult will it be to divert it into any other transit- lina) Hence in any complex aggregate of cells and fibres tH. XvI.] THE EVOLUTION OF MIND. 147 like the human brain, we may expect to find a countless number of transit-lines, of all degrees of permeability. Those which have been oftenest traversed will be the most permeable, and those which are traversed only at rare intervals will be but slightly permeable; while the passage of a nervous discharge in a new direction will involve the differentiation of a new line oi transit. Now subjective psychology furnishes us with an exact parallel to this state of things. The profound analysis of conscious changes carried on by the English school of psy- chology since the time of Hobbes, and accepted by the Kantian school in all save a few very important instances —which we shall presently see to be similarly explicable— has ended in the conclusion that states of consciousness cohere with a strength dependent upon the frequency with which they have been repeated in experience. In other words, “the persistence of the connection between states of consciousness is proportionate to the persistence of the con- nection between the agencies to which they answer. This fundamental law of association is illustrated by such familiar truths as the following :—“ that phenomena wholly unrelated in our experience, we have no tendency to think of together; that where a certain phenomenon has occurred in many rela- tions, we usually imagine it as recurring in the relation in which it has most frequently occurred; that when we have witnessed many recurrences of a certain relation we come to have a strong belief in that relation; that if a relation has been daily experienced throughout life with scarcely an exception, it becomes difficult for us to conceive it as other- wise—to break the connection between the states of con- sciousness representing it; and that where a relation has been perpetually repeated in our experience with absolute uniformity, we are entirely disabled from conceiving the negation of it.”} 2 Spencer, Principles of Psycholo,y, vol i. p. 421 L 2 148 COSMIC PHILOSOPHY, [p? u, The correspondence between the subjective and the objec- tive sides of the phenomena is thus complete, and the in- creasing complication of cell and fibre in the brain, from infancy to old age, is seen to have a psychological meaning, If the acquisition of a new idea is attended by the passage of a wave of molecular motion along a new path; and if recollection is a state of consciousness attending the trans- mission of a later wave along the same path; we have an adequate physical interpretation of the fact that the repeti- tion of an idea is favourable to the recollection of it. And we have also the physical interpretation of habit and pre- "judice. Molecular motions that have been repeatedly trans- ‘mitted between particular groups of nerve-cells, end by establishing more or less intricate webs of transit-lines which cannot be obliterated. No effort can prevent their occasional recurrence along these lines, or establish a nev: plexus of transit-lines, involving the derangement of the old unes. Late in life, when the ratio of repair to waste is greatly diminished, when the nutrition of the cerebral tissue is impaired, when the pulling to pieces and putting together of molecular clusters in which nutrition consists goes on slowly, then the formation of new sets of transit-lines be- comes especially difficult; and hence, as we say, the shaking off of old habits and prejudices, and the acquiring of new and strange ideas, is next to impossible. It is proverbially hard to teach an old dog new tricks. We may here also see why it is impossible to learn or to carry on complicated think- ing when in a state of anemia: the nutritive changes go on too slowly. Changes in memory further illustrate the slieoery. In youth, when the excess of repair over waste is at the maximum, but few discharges through any transit-fibre are needful in order to work a permanent nutritive change, set- ting up a line of communication which shall last through lift hence learning is easy and rapid, and memory is power- ful, In old age, when waste is slightly in excess of repair, on. xv1.] THE EVOLUTION OF MIND. 149 and both are at the minimum, a great many discharges are necessary for the achievement of any permanent nutritive change: hence learning is slow and difficult, and memory is feeble. And hence—what is most significant of all—the old man does not remember recent events, while he re- members very well what happened in his youth, when his rate of nutrition was rapid. These and countless similar facts show us that a state of consciousness and a nutritive change in the cephalic ganglia are correlated like the sub- jective and objective faces of the same thing. And thus are explained the many facts which in the seventh chapter were brought forward in illustration of the transformations of vital energy,—such as the facts that consciousness ceases the instant the carbonic acid in the blood kas attained a certain ratio to the oxygen; that much thinking entails a great ex- eretion of alkaline phosphates; and that prolonged mental exertion is followed by a bodily fatigue and a keen appetite not essentially different from the fatigue and hunger which follow muscular exercise. Regardiug it now as provisionally established that an association of ideas is dependent upon the formation of a transit-line between two nerve-cells, and that the more often the fibrous path is traversed the more indissoluble will be the association, let us proceed briefly to apply this doctrine to the explanation of sundry psychical phenomena. Now as we begin to examine the simplest psychical phenomena— those of reflex action and instinct—we are met by the seem- ing difficulty that indissolubly connected psychical states occur where the corresponding objective relation has never been repeated within the experience of the individual. In- stinctive adjustments of inner to outer relations are appa- rently made without any help from experience. Moths and butterflies take to wing immediately on emerging from the envelope of the chrysalis; “a fly-catcher, immediately after its exit irom the egg, hus been known to peck at and capture 150 COSMIC PHILOSOPHY. [Pr. 11. an insect” ; and “a young pointer will point at a covey the first time he is taken afield.” But in such cases as these, where the cohesion of psychical states has not been deter- mined by the experience of the individual, it has nevertheless been determined by the experience of the race. That the repetition of ancestral experiences must end in the automatic cohesion of psychical states, is both demonstrable d priort and illustrated by many facts. Birds living in islands un- inhabited by men will not fly away when approached by travellers, having none of that instinctive fear which “con- tinued experience of human enmity has wrought” in other birds. Yet in a few generations, these birds will acquire the same instinctive fear. In many cases the offspring of a dog that has been taught to beg will beg instinctively ; and various peculiarities of demeanour, carefully impressed by education upon sporting dogs, are manifested without educa- tion by their descendauts, Indeed it is familiar to breeders that the dispositions and instincts of domestic animals can be to a certain extent modified by training and selection, no less than their physical constitutions.} The physical explanation of the automatic cohesion of psychical states implied in hereditary instinct, is not diffi- cult at this stage of our inquiry. When the experience of many past generations has uniformly contributed to establish a certain arrangement of transit-lines in the chief ganglia of the animal, there must be a hereditary tendency for such 1 “How strongly these don-es‘ic instincts, habits, and dispositions are in- herited, and how curiously they become mingled, is well shown when lifferent breeds of dogs are crossed. Thus it is known that a cross with a bull-dog has affected for many generations the courage and obstinacy of greyhounds ; and a cross with a greyhound has given to a whole family of shepherd -dogs a tendency to iiunt hares. These domestic instincts, when thus tested by trossing, resemble natural instincts, which in a like manner become curiously dlended tovether, and for a long period exhibit traces of the instincts of either parent : for example Le Roy describes a dog, whose great-grandfather was a wolf, and this dog showed a trace of its wild parentage only in one way, by not coming in a straight line to his master, when called.”— Darwin, Irigin of Species, 6th edit., p. 210. . be. RVI] THE sVOLUTION OF MIND, 151 transit-lines to devsop by the mere process of nutrition. And where the psychical life is very simple, and but little varied from generation to generation, a nervous system em. bodying certain organized aptitudes will be transmitted as surely as the muscular or vascular system is transmitted Nervous discharges will run along pre-established transit lines as inevitably as in human beings the nervous discharges which regulate the respiratory and alimentary movements run in permanent channels. The character of the process is best exemplified in reflex action, the simplest form of psychical life. In reflex action, which is unaccompanied by conscious- ness, a single inner relation is adjusted to a single outer relation. For the simpler kinds of reflex action nothing is needed but what is called a nervous arc,—that is, an afferent nerve, a ganglion, and an efferent nerve. When a person sound asleep draws away a limb that is touched, the impres- sion is simply carried along an afferent nerve to one of the spinal ganglia, and thence reflected along an efferent nerve - to the muscle which moves the limb. The assistance of the brain is not needed. In many animals the limbs thus respond to stimuli after the head has been cut off or the brain sliced away. ‘his kind of psychical life, which is but one degree removed from purely physical life, is all that is manifested by those lowly-organized animals whose nervous systems consist of simple arcs. So thoroughly physical is this croup of phenomena that it may seem almost inappropriate to call it psychical: nevertheless it forms the transition from the one kind of life to the other. It is the lowly beginning from which higher forms of psychical activity arise. Now in reflex action, as it is exemplified alike in the rhythmical movemauts of our heart, lungs, stomach, and other viscera, and in the contraction of a polyp’s tentacle when food comes against it, we see a series of nervous dis- charges which are automatically directed along certain definite \ransit-lines, The lines of least resistance have become per- 152 COSMIC PHILOSOPHY, [rr. 0. manently organized in the animal structure, and they are transmitted, with the accompanying capacities of action, from generation to generation. Here we see “ indissolubly connected psychical states existing where there are per- petually repeated experiences of the external relations to which they answer.” The phenomena of instinct are more distinctly psychical than those of reflex action. ‘ While simple reflex action is common to the internal visceral processes and to the pro- cesses of external adjustment, instinct is not. There are no instincts displayed by the kidneys, the lungs, the liver: they occur only among the actions of that nervo-muscular appa- ratus which is the agent of psychical life.” Instinct, more- over, implies the coordination of a large number of stimuli with the answering movements, and herein is its chief dif- ference from reflex action,—a difference in degree only. The newly-hatched fly-catcher, in seizing a fly, shows “ en exact appreciation of distance, as well as a power of precisely regulating the muscular movements in accordance with it.” The number of impressions and movements here coordinated is so considerable that it would take several pages to describe them thoroughly. Here certain systems of transit-lines, involved in the establishment of a correspondence in space, are wrought by nutrition in the animal’s nervous system, so completely that when the outer relation occurs the discharge instantly takes place along the pre-established channels, and the adjustment is made. There is an intricate compounding of reflex actions, involving the assistance of the brain ; for if the cerebellum be sliced, the fly-catching can no longer be performed, Intricate, however, as the combination is, it is a special and unvarying one which has been continually re- peated during the whole lifetime of countless ancestral fly- catchers, so that there is nothing strange in the fact that it is completely organized at birth. The principle is the same as in the simpler phenomena of refiex action. Here, as before ? cH, xv1.]} THE EVOLUTION OF MIND. 153 extending the experience theory to the entire race, we see «“ indissolubly connected psychical states existing where there are perpetually repeated experiences of the external relations to which they answer.” Though the higher kinds of instinct, in which the supreme yanglia cooperate, are probably accompanied by a vague con- sciousness, yet in the main the processes which we have just described must be regarded as automatic. Let us now notice what must occur when the correspondence between inner and outer relations has become quite complex and special. As Mr. Spencer has pointed out, “phenomena become less frequent in proportion as they become more complex; and hence the experiences of them can never be so numerous as are the experiences of simple phenomena. The relation between a passing obscuration and a living body, recurs oftener than the relation between a certain degree of obscura- tion and danger, or than the relation between a certain other degree of obscuration and food. Again, each of these rela- tions is more general than the relation between a particular size and form of visual impression and an object of a particular class. And again, this relation is more «general than that between a particular size, form, and colour of visual impression, and a certain species of that class.”+ From this it follows that a lowly-organized animal, in which there is established a correspondence only with the most general euvirouing relations, and which therefore has experience only of such most general relations, has at the same time a uniform experience which maintains a complete cohesion among its simple psychical states. On the other hand, a _ highly- organized animal, in which there are established correspond- ences with many complex and special relations, will have a varied experience, and at the same time a varying cohesion among its complex psychical states. While the most general relations which it experiences will also be the most frequent, 4 Spencer, Principles of Psychology, vol. i. p. 441, 154 COSMIC PHILOSOPHY, Pr. 1h and while sundry special relations (as in the seizing of its prey by the fly-catcher) will be extremely frequent, there are many other special relations of which the experience will be much less frequent. And accordingly, along with the per- fectly coherent psychical states generated by the former, there will be a congeries of less coherent psychical states generated by the latter. Or, to restate the case in physiological language :—While in the lower organism there will be a number of transit-lines permanently established, and scarcely any tendency toward the formation of new ones; on the other hand, in the higher organism, there will be a number of permanent transit-lines and a number of such lines in process of formation, along with a continual tendency toward the establishment of new ones. The consequences of this are obvious. In becoming more and more complex, the correspondences become less and less instantaneous and decided. ‘They gradually lose their distinctly automatic character, and that which we call Instinct merges into some- thing higher.” For as long as the psychical life consists solely in the passage of nervous undulations along permanent pre-esta- blished channels, there is no consciousness. Consciousness, as already shown, implies continual discrimination, or the continual recognition of likenesses and differences; and this process implies a rapid succession of changes in the supreme ganglia. Now this rapid succession of changes occurs when a vast number of relations are brought together in a single eanglion, or group of ganglia, as in the cerebrum, in order to be compared with each other. Besides this, consciousness implies a certain lapse of time during which impressions persist ; and there is no such persistence in reflex action, or in the lower forms of instinct, where the molecular disturbance constituting a nervous impression is instantly drafted off along the pre-established channels. Such persistence occurs only when a number of impressions are brought together in Ci. XVI.] THE EVOLUTION OF MIND. 155 a single ganglion, where an appreciable time must elapse before they are carried off each along its own set of transit- lines. For example, when you tickle or pinch the arm of a person asleep, the arm is at first withdrawn by simple reflex action: the ordinary channel, through the afferent nerve te the spinal centre and back again through the efferent nerve tc the limb, suffices to carry off all the molecular disturbance, —and there is no consciousness of the irritation or of the resulting contraction. But if the pinching be frequently repeated, so that the disturbance is generated faster than it can be thus drafted off, the surplus is sent up through a centripetal fibre from the spinel ganglion to the brain ; and some dreaming ensues, or perhaps a fretful sound is emitted. If the impression be kept up long enough, there is full con- sciousness of it, and the person awakes. Now the rise of consciousness implied in the dreaming and waking is due to the persistence in the cerebrum of a molecular disturbance which is not at once drafted off through the proper centrifugal ‘fibres. Obviously, therefore, when the number of impressions sent in to the brain from moment to moment exceeds the number of thoroughly permeable channels which have been formed there, so that there is a brief period of tension during which occur the nutritive changes implied in the transmission of the disturbance through the appropriate channels, then there arise the phenomena of conscious intelligence. For mark what must happen. In the first place, the persistence of the impressions enables them to be consciously felt, either pleasurably or painfully ; so that there is the germ of Emo- tion. Secondly, the disturbance tends to propagate itself along various permeable transit-lines, so that there is a revived association of ideas, or what we call Memory. Thirdly, there is an integration of the present impressions with such past ones as they resemble, and a differentiation of them from such past ones as they do not resemble; and this 156 COSMIC PHILOSOPHY. [rv. m comparison of present with past impressions, dependent on memory, implies classification, and is the germ of what we call Perception and Reasoning. Jouwrthly, there is, in the case of many kinds of impressions, a period of tension during which it becomes determined along what set of centrifugal fibres the surplus disturbance shall be drafted off, and here we have the primitive form of Volition. Thus the various phases of conscious psychical life—which we call emotion, memory, reason, and volition—arise as soon as there begins to elapse an appreciable time between the accumulation of molecular disturbance in a group of cephalic nerve-cells, and its discharge along the proper transit-fibres. And this state of things, which is not possible in simple nervous systems which only respond instinctively or by reflex action to a few general relations in the environment, becomes possible in those com- pound nervous systems which respond to a great number of infrequent and special relations. For the establishment of inner relations, answering to these infrequent and special outer relations, involves a lapse of time during which numer- ous diverse impressions are getting distributed through various transit-lines hitherto little used. When, as in the fully- developed human cerebrum, a vast number of infrequent and special relations are continually set up, there is a maximum of nutritive change, there is a maximum of time during which impressions simultaneously coming in may be com- pared and classified, and there is a maximum of con- sciousness. This explanation of the way in which the various phases of conscious psychical life arise, is fully confirmed by the way in which they disappear when actions at first con- sciously performed become instinctive. The confirmation is so complete as to afford a very strong proof of the truth of the hypothesis. Many of the actions performed by civilized man are designated by psychologists as “ second- arily automatic.” That is, they are at first performed with f 4 ¥ cH. XVI] THE EVOLUTION OF MIND. 157 the assistance of reason, volition, and conscious memory, and they are attended by feelings of pleasure or pain. But after a while they are performed without the aid of reason, volition, or conscious memory, and they are not attended by pleasurable or painful feelings. In becoming instinc- tive, they lapse partially or entirely from consciousness. The child in learning to walk and talk, must will each movement and rationally coordinate it with other move- ments in order to attain the desired end. But the man, in walking and talking, is unconscious of the separate move- ments, and volition serves only to set them going. In learn- ing to read, the child must consciously remember each letter, combine it with others into a word, and associate the word with the thing signified; and this last process is repeated in later years when we learn foreign languages. But in reading our own language, or a foreign one which has been thoroughly learned, the association of words and things is automatic. In reading an English book, in which French quotations are inserted, one frequently passes from one language to the other and back again, without noticing the change, if the attention be concentrated on the subject-matter. In learn- ing to play the piano, there is at first a vast amount of con- scious association between the written notes, the key-board, and the muscular adjustments of the fingers, wrists, and arms; but an accomplished pianist will play a familiar piece while his attention is directed to other matters. The case is similar with writing, and indeed with all habitual actions which require nervo-muscular coordination. In many cases, moreover, the intervention of conscious attention only impairs the accuracy of adjustment. In billiard-playing and rifle-shooting, the aim is usually im- paired if we stop to think about it; and on the piano it is almost impossible to play triple notes with one hand and double notes with the other if we attempt to measure out the time, 158 COSMIC PHILOSOPHY, [er. 0 Purely intellectual acts also become to a certain extent automatic with practice, as was indeed implied in some of the foregoing illustrations. Not only the combination of words into a sentence, but the combination of sentences into a proposition, and the combination of propositions into a theory, is effected more and more rapidly, until the pro- cess hardly attracts attention. In a complicated exposition like the present, numerous scientific theorems, at first laboriously comprehended one by one, are wrapped up to- gether and thrown into some subordinate clause of a sen- tence, the total being so obvious as not to withdraw the attention from the main current of thought while writing. In such facts we have a partial explanation of many of the phenomena of what is called unconscious or “ sub-con- scious” thinking. And thus, too, are to be explained those sudden flashes of insight, scientific or poetical, which in early times were attributed to inspiration or dictation from without. Obviously without a good deal of such automatic acting and thinking, we could achieve but little in art or science. We should never become good pianists if we had to keep paying attention to all the requisite muscular ad- justments; and science would advance but slowly if at each step of an intricate inquiry in dynamics it were neces- sary to stop and reflect upon the elementary laws of matter and motion. The physical interpretation of these secondary automatic processes is not difficult, according to the hypothesis here expounded. During the process of learning, there is an extensive formation of new trausit-lines, and consequently an appreciable interval between the accumulation of mole- cular disturbance in the cerebral cells and its discharge, Impressions persist. long enough to be compared together, and accordingly there is reason and there is volition. There is a maximum of consciousness, because there is a maximum duration of the nutritive changes, and hence weariness soon cH, Xv1.] THE EVOLUTION OF MIND. 159 follows; cerebral nutrition entailing greater waste than occurs in any other part of the system, But with constant repetition the resistance to the passage of undulations along the new transit-lines disappears entirely. Nutrition has so modified them that, as above explained, they become lines of traction instead of lines of resistance. As we say, nothing can prevent the one group of ideas or movements from following the other. The discharges are made instantly, and along with a minimum duration of nutritive change there is a minimum of consciousness. The combinations become permanently organized in the brain-structure, and in becoming permanently organized they become instinctive or automatic, | We may now also begin to understand why it is that in man the organization of instincts, primary and secondary, is continued through the early years of life, while in the other animals the majority of the instincts are already organized at birth. The distinction is not an absolute one, as many of the higher vertebrates, both birds and mammals, and ina marked degree the anthropoid apes, cannot take care of themselves immediately after birth, though they soon become able to do so. The lower we descend the animal scale, the more completely organized is the psychical life of the newly- born organism, The reason is obviously to be found in the greater speciality and complexity, and the consequent rela- tive infrequency, of the coordinations made by the highest animals, and especially by man. When, for example, we put forth the hand to grasp an object, the muscular adjust- ments are as instinctive as those of the fly-catcher pouncing on an insect; “volitin being concerned merely in setting the process going.” But with us, the impressions which we receive and the motions which we make are endlessly varied, and the complex combinations of them occur severally with less frequency than is the case with the simpler combina- tions. formed by lower animals. They are accordingly not 160 OUSMIC PHILOSOPHY. [er. coordinated before birth, though they are easily coordinated during childhood. A great number of psychical phenomena are thus satisfac- torily explained by the hypothesis, But one further service, and a most signal one, is rendered by it; and this we must briefly indicate, in accordance with previous promises, before leaving the subject. The view of cerebral action here adopted settles the long-vexed question between the Lockian and Kantian schools as to the sources of knowledge; and the verdict, while partly favourable to each of these schools, is not wholly favourable to either. Let us reconsider the portion of our hypothesis which bears upon this question. It follows from the general principles involved in the foregoing exposition, that the peculiar intellectual activity of any parent, by modifying the nutrition of his cerebral tissue, must Impress itself upon the unstimulated and _ half- developed brain of his infant offspring. Eliminating the effects wrought in it by countless environing circumstances, we may say that the infant brain just as surely tends to develop transit-lines similar to those in the parental brain, as the infant face tends to develop muscular peculiarities of expression like those characteristic of the parental face. And while the tendency is so slight as to count for little or nothing in the case of the more complex and infrequent associations of ideas, it must be a resistless tendency in the case of those nerve-connections which answer to associa- tions involved in every act of experience,—as, for example, those concerned in building up our conceptions of space, time, force, and causation. A concise restatement of the case will now lead us at once to our conclusion, While ancestral experience impresses upon the brain a nutritive 1 In the concluding chapter of this Part, I shall endeavour to show that this origination and prolongation of the period of infancy, which is the effect oi increasing intelligence, is in turn the proximate cause of the genesis of social relations and of ethical feelings, and thus, indirectly, of the entire intellectual and moral supremacy of man. cH. XVI._ THE EVOLUTION OF MIND. 161 tendency toward the formation of certain special nerve- connections, individual experience tends now to assist and now to check the inherited tendency. And so the number and direction of transit-lines in any brain is due to the cooperation of innumerable ancestral and individual ex- periences, Locke was therefore wrong in calling the infant’s mind a blank sheet upon which experience is to write know- ledge. The mind of the infant cannot be compared to a blank sheet, but rather to a sheet already written over here and there with invisible ink, which tends to show itself as the chemistry of experience supplies the requisite conditions. Or, dropping metaphor, the infant’s mind is correlated with the functions of a complex mass of nerve-tissue which already has certain definite nutritive tendencies. On the other hand, the school of Leibnitz and Kant was wrong in assuming a kind of intuitional knowledge not ultimately due to experience. For the ideas formerly called innate or intuitional are the results of nutritive tendencies in the cerebral tissue, which have been strengthened by the uni- form experience of countless generations, until they have become as resistless as the tendency of the dorsal line of the embryo to develope into a vertebral column. The strength of Locke’s position lay in the assertion that al) knowledge is ultimately derived from experience,—that is, from the intercourse between the organism and the environ- ment. The strength of Kant’s position lay in the recogni- tion of the fact that the brain has definite tendencies, even at birth, The Doctrine of Evolution harmonizes these two seemingly-opposite views, by showing us that in learning we © are merely acquiring latent capacities of reproducing ideas; and that beneath these capacities lie more or less poweriul autritive tendencies, which are transmissible from parent to -hild. I believe that the last difficulties which may have hovered about the doctrine of the Test of Truth, expounded iu the VOL, II. M 162 COSMIC PHILOSOPRY. (pr. 1 third chapter of our Prolegomena, are now swept away. It must be by this time quite clear that the inconceivability- test and the experience-test are merely the obverse faces of the same thing. An association of subject and predicate, which answers to an objective relation of which the ex- perience has been absolutely uniform, must be absolutely indissoluble ; and, vice versa. The ultimate question at issue between Mr. Mill and Mr. Spencer thus becomes reduced to a question of terminology, save in one important particular, in which I have already shown that Mr. Mill is not only demonstrably wrong, but also inconsistent with himself. The foregoing exposition adds new weight to the argument by which it was formerly (Part I, Chap. iii.) proved that when Mr. Mill asserts that the negation of such an axiom as the indestructibility of matter, which is now inconceivable, was in past times conceivable, he virtually asserts that there was a time when men could frame inner relations of which the corresponding outer relations had never been presented in experience. And thus he not only runs counter to the general theory of Life as Adjustment which is here adopted, but he contravenes his own favourite doctrine of the ex- periential origin of all knowledge, which is in reality part and parcel of that general theory of life. With these corollaries I must conclude this too brief account of the process of psychical evolution. In the present chapter and its two predecessors, while steadily refraining from the chinerical attempt to identify Mind with some form of Matter or Motion, it has nevertheless been shown that, owing to the mysterious but unquestionable correlation which exists between the phenomena of Mind and the phenomena of Matier and Motion, it is possible to describe the evolution of the former by the same formula which describes the evolution of the latter. By a continuous dif- ferential compounding of impressions, we pass, through infinitesimal stages, from the relatively homogeneous and simple set of correspondences known as reflex action, mani- CH. XVI.] THE EVOLUTION OF MIND. 163 fested alike by the highest and the lowest animals, to those exceedingly complex and heterogeneous sets of correspond- ences known as reason and volition, which are manifested only by the highest animals, and in their greatest complexity by man alone. Throughout this wonderful process we have seen how closely the evolution of psychical function is correlated with the evolution of nerve structure. But, great as has been our gain during the foregoing exposition, our theory of psychical evolution is as yet by no means com- plete. Concerning the relations of Mind to Life, and con- cerning the Composition and Evolution of Mind in general, we have obtained many valuable results, But nothing has as yet been said concerning the especial mode of genesis of those highest manifestations of thought and feeling which distinguish civilized man. This problem must be duly treated before our account of psychical evolution can be regarded as complete even in outline. Upon questions of this sort, however, we are not yet prepared to enter. Those highest manifestations of thought and feeling which dis- tinguish civilized man from inferior mammals, and in a less- marked degree from uncivilized man, are the products of countless ages of social evolution; and before we can hope to understand their mode of genesis, we must see what are the teachings of history and psychology cencerning the character of social evolution in general. Having shown how, starting from a relatively low degree of sociality, a relatively high degree is attained in conformity to the general theory of Life as Adjustment, we shall be better enabled to comprehend the genesis of that lowest degree of sociality, the attainment of which was the decisive step which first raised Man above the level of the Brutes. The four following chapters will therefore be concerned with Sociology; and the first will be devoted to clearing away a complicated misunderstanding, by the help of which metaphysicians have long sought, and still seek, to deter us from applying scientific methods of interpretation to the phenomena of human history. mM 2 CHAPTER XVIL SOCIOLOGY AND FRFE-WILL THAT the phenomena manifested by human beings, as grouped in societies, conform to fixed and ascertainable laws, is a pro- position which has thus far been taken for granted, inasmuch as it is logically inseparable from the other sets of proposi- tions which go to make up our Cosmic Philosophy. Not only, moreover, have we thus tacitly assumed that social phenomena conform to law and may be made the subject of science, but in the fourth chapter of this Synthesis it was expressly stated that the fundamental law to which they conform is the Law of Evolution, which has now been proved to hold sway among inorganic and organic phenomena, as well as among those super-organic phenomena which we distinguish as psychical. Under ordinary circumstances we might fairly go on and justify our tacit assumption and our explicit assertion, by showing, both deductively and inductively, that the evolution cf society follows in general the same method as the evolu- tion of organic life. In the following chapter I shall proceed to do this. I shall show, first, that social evolution consists in the integration of human families or tribal communities into larger and larger groups, which become ever more heterogene- ous and more interdependent ; and secondly, that what we call civilization consists in the ever increasing definiteness and complexity of the correspondence between the community CH, XvIr.] SOCIOLOGY AND FREZ-WILL. 165 and the environment. Thirdly, I shall carry on the inquiry to a point somewhat in advance of Mr. Spencer's exposition, as it now stands, and show how these truths must be supple- mented in order to give usa law of social evolution which shall cover social phenomena simply, excluding the more general phenomena of organic life. But while under ordinary circumstances it might be well enough to proceed directly to such an investigation, since there is no better way of proving that certain groups of phenomena conform to law than by pointing out the law to which they conform, nevertheless in the present case I think it desirable to preface the inquiry with a brief discussion of one or two logical and psychological truths—truths of method and of doctrine—which lie at the basis of sociology. In our survey of the simpler sciences, no such preface was called for. In beginning to treat of biological truths, we did not deem it necessary to prove that waste and repair proceed according to immutable laws, or to forestall possible cavils by declaring that, although we cannot predict our states of health from week to week, nevertheless organic phenomena are not the sport of chance. It is otherwise in sociology, which is a new science, encumbered with many popular misconceptions, and regarded with an evil eye by theologians——persons who profess great devotion to the interests of advancing knowledge in general, while the particular advance in knowledge at any time going on somehow never happens to be the one which they think fit to regard with favour. Of each new trophy which Science has from time to time laboriously won, these opponents have hastened to declare, “ Behold it is the last!” Lhough the phenomena presented by the heavenly bodies, by the surface of the earth, and by the life which covers the earth, have one after another, in spite of vehement theological protest, been made the subjects of science,! it is still stoutly 1 “Als Pythagoras seinen beriihmten Lehrsatz entdeckte, opferte er den Gottern eine Hekatombe, d. h. ein Opfer von hundert Stieren, Seitdem 166 COSMIC PHILOSOPHY. [pr. 1. maintained that the results of human volitions can never become amenable to scientific treatment. Here, it is cried. on the threshold of sociology we must take our final stand, and insist, in the interests of religion and morality, that although all other events may occur in regular sequence, nevertheless in human affairs there is no such sequence, The arguments by which it is sought to establish this desperate proposition, are based partly on those facts which are assumed to prove the freedom of the will, partly on the endless diversity and complexity of human affairs. Concerning this latter class of considerations, I may say here that they are at once irrelevant and inconclusive. Irrelevant, since even if it were to be granted—which it is not—that the extreme intri- cacy of social phenomena imay prevent our discerning the order of their sequence, this would prove, not that there is no sequence, but that our vision is limited. Inconclusive, because from the nature of the case, other things being equal, com- plex phenomena cannot be generalized until the simpler phenomena which they involve have been mentally reduced to orderly succession. As we shall again have occasion to notice, the laws of social life could not be discovered until the sciences of biology and psychology had gone far toward formulating the laws of physical and psychical life in general. But the misconceptions which cluster about this subject are so numerous that they may best be eliminated by a somewhat detailed controversy. Let us examine the argument from complexity, as presented by Mr. Froude; and afterwards the argument from the assumed lawlessness of volition, as pre- sented by Mr. Goldwin Smith. Mr. Froude begins! by dogmatically denying that there is or can be such a thing as a science of history. There is something incongruous, he says, in the very connection of briillen alle Ochsen, so oft eine neue Wahrheit entdeckt wird.”—Biichner, Die Darwin’sche Theorie, p. 288. 1 Short Studies on Great Subjects, vol. 1, eH, XVII. | SOCIOLOGY AND FREE-WILL. — 167 the two words. “It is as if we were to talk of the colour of sound, or the longitude of the rule-of-three.” But he carries on the thought in a way that shows plainly his reluctance to grapple fairly with the problem. In his next sentence lie says, “where it is so difficult to make out the truth on the commonest disputed facts in matters passing under our very eyes, how can we talk of a science in things long past, which come to us only through books?” Now to reason like this, is merely to shrink from the encounter. For the question is, not whether the science is difficult, but whether it is possible. Mr. Froude sets out to show that there can be no such science, and his first bit of proof is that, if there is such a science, it must be far more difficult than any other; a position which we may contentedly grant. Let us follow him a step farther. “It often seems to me as if history were like a child’s box of letters, with which we can spell any word we please. We have only to pick out such letters as we want, arrange them as we like, and say nothing about those which do not suit our purpose.” And what does all this amountto? Is this Mr. Froude’s idea of historical investigation? Why, the same thing may be done in any science. We have only to pick out all the facts on one side, and blink all the facts on the other side to prove the veracity of every oracle, soothsayer, and clairvoyant that ever existed, the validity of every paltry omen, the credibility of every crazy notion of alchemy or judicial astrology. In this way we may prove that the homceopathist always saves his patient, while the allopathist always kills him; or vice versa. And it was in this way that the phrenologists erected their pseudo- science. By following this method, also, it becomes easy to prove that Henry VIII. was an exemplary husband. It is in this way that every incorrect or inadequate hypothesis in physical science or in history has arisen and gained temporary recognition. Supposing Tycho Brahe had said to his Coper- nican antagonists, “ Astronomy is like a child’s box of letters; 168 COSMIC PHILOSOPHY. [pr if we take out what we want and let the rest go, we can spell whatever we please; I spell out the Ptolemaic hypo- thesis, and will therefore abide by it ;”—he would have been talking much after the manner of Mr. Froude. It is true, as Mr. Froude further says, that one philosopher believes in progress, a second in retrogression, and a third, like Vico, in ever-recurring cycles. But is this because the facts are undecipherable, or because the investigation is one-sided ? Because Agassiz still believes organic species to be fixed, while almost all other naturalists believe them to be variable in character, are we to infer that there is no science of biology ? In such unworthy plight does Mr. Froude retreat before the problem he has encountered. He starts to show us that a science of history is as ridiculous an impossibility as a scarlet B-flat or a westerly proportion ; and he ends by mildly observ- ing that history is a difficult subject, in which a series of par- tial examinations may bring forth contradictory conclusions! The next bit of inference concerns us more intimately. « Will a time ever be when the lost secret of the foundation of Rome can be recovered by historiclaws? If not, where is our science?” Just where it was before. The science of history has nothing to do with dates, except to take them, so far as they can be determined, from the hands of historical criticism. They are its data, not its conclusions. As Mr. Morley reminds us, we do not dispute the possibility of a science of meteorology, because such a science cannot tell us whether it was a dry or a wet day at Jericho two thousand years ago. Facts like these show us that sciences dealing with phenomena which are the products of many and complex factors, cannot hope to attain that minute precision which is attained by sciences dealing with phenomena which are the products of few and simple factors. They show that sociology cannot, like astronomy, be brought under the control of mathe- matical deduction. But it was not necessary for Mr. Froude to write an essay to prove this. on. xvit] SOCIOLOGY AND FREE-WILL. 169 But, continues Mr. Froude, “can you imagine a science which would have foretold such movements as” Moham- medanism, or Christianity, or Buddhism? To the question as thus presented, we must answer, certainly not. Neither can any man foretell any such movement as the typhoid fever which six months hence is to strike him down. If the latter case does not prove that there are uo physiologic laws, neither does the former prove that there are no laws of history. In both instances, the antecedents of the pheno- menon are irresistibly working out their results; though, in both cases, they are so complicated that no human skiil can accurately anticipate their course. But toa different present ment of Mr. Froude’s question, we might return a different answer. ‘There is a sense in which movements hike Moham- medanism, or Buddhism, or Christianity, could not have been predicted, and there is a sense in which they could have been. What could not have been predicted was the peculiar character impressed upon these movements by the gigantic personalities of such men as Mohammed and Omar, Sakyamuni, Jesus and Paul. What could have been predicted was the general character and direction of the movements. For example, as I shall show in the following chapter, Christianity as a universal religion was not possible until Rome had united in a single commonwealth the progressive nations of the world. And when Rome had accomplished this task, it might well have been predicted that before long a religion would arise, which should substitute monotheism for polytheism, pro- claim‘ng the universal fatherhood of God, and the universal brotherhood of men. I admit that such a prediction could have been made only by a person familiar with scientific modes of thought not then in existence; but could sucha person have been present to contemplate the phenomena, he might have foreseen such a revolution in its main features, as being an inévitable result of the interaction of Jewish, Hellenic and Roman ideas. J am inclined to think he might 170 COSMIC PHILOSOPHY. (er. th have foreseen that it would arise in Palestine, that its spread would be confined to the area covered by Roman civilizaticn, and that its work would for a long time be most thorough in the most thoroughly Romanized regions, We do not need, however, to insist upon this point. Forin none of the concrete sciences is there anything like thorough and systematic prevision, save in astronomy; and even in astronomy, our foresight becomes precarious as soon as we pass beyond the solar system, and begin to inquire into the results of the mutual gravitation of the innumerable stellar bodies. We know that our sun is rushing, with immense velocity, toward the constellation Hercules; but we cannot yet trace his orbit, as Kepler traced the orbit of Mars. When we come to biology and psychology, the power of accu- rate prevision is very small; yet no one denies that the phenomena of life and intelligence conform to fixed and ascertainable laws. In sociology we must expect still less ability to predict. The truth is, as Comte acutely pointed out, that while in the simpler sciences our object is gained if we can foretell the course of phenomena so as to be able to regulate our actions by it, in the more complex sciences our object is gained when we have generalized the conditions under which phenomena occur so as to be able to make our volitions count for something in modifying them. We cannot modify astronomic phenomena, but we can predictthem. We cannot predict, save to a limited extent, biologic phenomena; but, knowing more and more thoroughly the conditions under which they occur, we can more and more skilfully modify them so as to ensure health or overcome disease. And obviously even this limited ability to modify the phenomena implies a certain amount of prevision,—quite enough to justify us in asserting that the phenomena conform to law. The case is similar in sociology. Though we may not be able definitely to predict a given political revolution, we may nevertheless understand the general movement of affairs and cH. xvi.) SOCIOLOGY AND FREB-WILL. 171 the effects which certain kinds of legislation are likely to ‘produce, so as to hasten a desired result or avert social mis- chief. Upon this possibility are based all our methods of government and of education. And, as in biology, this ability to modify the phenomena proves that the phenomena occur in some fixed order of sequence. For if there were phenomena without any definite order of sequence, we could neither predict nor modify them ; and where there is a definite order of sequence, there is, or may be, a science. Now in denying that there is or can be a science of history, Mr. Froude, if he means anything, means that social affairs have no fixed order of sequence, but are the sport of chance. Either Law or Chance—these are the only alternatives, unless we were to have recourse, like the Mussulman, to Destiny, an illegitimate third idea, made up of the other two misconceived and mutilated in order to fit together. But for the modern thinker there is no middle course. It is either symmetry or confusion, law or chance, and between the two antagonist conceptions there can be no compromise. If the law of causation is universal, we must accept the theory of law. If it has ever, in any one instance, been violated, we may be excused for taking up with the theory of chance. Now we know that all the vast bodies in this sidereal universe move on for untold ages in their orbits, in strict conformity to law. In conformity to law, the solar system in all its complexity has grown out of a homogeneous nebula; and the crust of the cooling earth has condensed into a tigid surface fit for the maintenance of organic life. Out of plastic materials furnished by this surface and the air and moisture by which it is enveloped, organic life has arisen and been multiplied in countless differing forms, all in accordance with law. Of this aggregate of organic existence, man, the most complex and perfect type, lives and moves and has his being in strict conformity to law. His periods of activity and repose are limited by planetary rotations 172 COSMIC PHILOSOPHY. [PT. 11. His achievements, physical and mental, are determined by the rate of his nutrition, and by the molecular structure and relative weight of the nervous matter contained in him. His very thoughts must chase each other along definite paths and contiguous channels marked out by the laws of association. Throughout these various phenomena, already generalized for us by astronomers, geologists, biologists, and psychologists, we know that neither at any time nor in any place is law interfered with,—that yesterday, to-day, and for ever, the effect follows the cause with inevitable and inexorable certainty. And yet we are asked to believe that in one particular corner of the universe, upon the surface of one little planet, in a portion of the organism of one particular creature, there is one special phenomenon, called volition, in which the law of causation ceases to operate, and everything goes helter-skelter ! Such is the demand which Mr, Froude makes upon our powers of acquiescence, and such is the theory which Mr. Goldwin Smith, in the interests of theology, pronounces it unphilosophical, if not impious, for us to reject. Of the Science of Higtors: Mr. Smith asserts that “it extinguishes all sympathy”; it “must put an end to self-exertion ” ; it “would diasalyn the human family”; it makes man the anh helpless of animals, no better in fact than “ a beast or a blade of yrass” ; it degrades humanity to mere clay; it establishes “a strange contradiction between our outward observation and our inward consciousness; it makes us “render up our personality,” and become “a mere link in a chain of causa- tion, a mere grain in a mass of being”; it builds up, “with much exultation,” an “adamantine barrier of law’—what- ever that may be—between man and the source of all good- ness; and, to crown all, it tells us that “conscience is an illusion,” and prevents our having any “rule of right action.”? 1 Lectures on the Study of History, pp. 63, 67, 48, 82, 85, 87, 59.

XviI.] SOCIOLOGY AND FREE-WILL. 173 - Hard words are as powerless to overthrow as to establish a philosophical theory. In scientific inquiry the ability to weigh evidence goes for much, but facility in declamation goes for little. And to anyone who has been brought up amid scientific pursuits, there is but little that is instructive or edifying in the fervid rhetoric of a writer who, in attack- ing a disagreeable doctrine, prefers to stigmatize i* as dis- acreeable, rather than to show that the evidence is against it. Nevertheless beneath the emotional assertions just quoted there lies a complicated theoretical misconception, the cha- racter of which it is worth our while to examine. The well- worn argument is that unless the human will were “ free,” there could be no responsibility, and therefore no morality ; that if volitions are caused, even though it be by our own desires, we are all in a condition similar to that of the man who has made a promise under duress, to whom neither praise nor blame can justly be attached for the manner in which his promise is kept. ‘ It is popularly supposed that there is something very forcible in this argument; and that, when coupled with the opposing arguments drawn from such sequences as are easily traceable among human affairs, the result is a puzzle which must for ever remain insoluble. The problem of free-will has been described by poets, and is customarily regarded, as the most difficult problem which can occupy human atten- tion; and we frequently hear it said that it ean never be feelings to run away with them when treating of this question.— Not the picture of a man; but the representation of an automaton that is what it cannot help being; a phantom dreaming what it cannot but dream; an engine performing what it must perform ; an incarnate reverie ; a weather- cock shifting helplessly in the winds of sensibility ; a wretched , association- machine, through which ideas pass linked together by laws over which the machine has no control; anything, in short, except that free and self-sus- tained centre of underived, and therefore responsible activity, which we call Man” ;—such, says Prof. Ferrier, is “the false representation of man which philosophy invariably and inevitably pictures forth whenever she makes cominon cause with the natural sciences.” — Lectures and Philosophical Remains, vol. ii. p. 195, Verily the free-will question is a great opener of the food-gates of rhetoric! vp , 174 CUSM1IC PHILOSOPHY, [Pr. 14, completely solved, But in reality all this perplexity is the result of the desperate muddle into which metaphysics has brought the subject. Strip the question of the peculiar meta- physical jargon in which it is usually propounded, restate it in precise scientific language, and it becomes a very easy question to auswer. Would that science presented none more difficult! Confused and inaceurate verbiage is respon- sible for the chronie disputation upon this subject. No- where else is Berkeley’s complaint so thoroughly applicable, that in dealing with metaphysics men first kick up a dust and then wonder why they cannot see through it. Those who have come to regard the question from a purely scientific point of view, also regard it as thoroughly settled; and the need for refuting such arguments as the one above cited, they class among the needs, too often thrust upon us, of refuting fallacies already thrice exploded, In illustration of this, let us notice the theory which the free-will argument implies concerning the nature of volition. The theory implies that over and above particular acts of volition, there is a certain entity called “The Will,” which is itself a sort of personage within the human personality. This entity, called “The Will,” is supposed to have desires and intentions of its own, which the causationists are sup- posed to declare constantly liable to be frustrated by external agencies, In opposition to this imaginary heresy, it is asserted that this autocratic Will is “ free,” and sitting in judgment over “motives,” may set aside the stronger in favour of a weaker, or may issue a decree in defianceof all motives alike. Some such erude conception as this is im- plicitly conveyed by every statement which, alluding to the Will as an entity, ascribes “ freedom” to it. Only by means of such a conception can the phrase “freedom of the Will”. be shielded from the imputation of nonsense, Only thus can the argument above cited be regarded as relevant to the subject in dispute. For if Will be not conceived as an eH. XVII.) SOCIOLOGY AND FREE-WILL. 175 entity acting under conditions, then no comparison can be made between caused volition and constrained behaviour. If instead of “The Will” we look at the act of willing— which is not an entity, but a dynamic process—then it be- comes absurd to talk of this act as being either free or not free, and we must seek for some other word than “freedom” by which to designate its alleged want of causal connection with preceding psychical states, Now the tendency to erect relations and processes into entities is a tendency which modern metaphysics has in- herited from a mischievous mode of thought current in ancient times and rather loosely known as “Realism.” Among metaphysicians, unused to the habits of thought which science nurtures, the tendency is an almost irresistible one. Civilization, for example, is opviously a process, but Dr. Whately continually speaks of it as if it were a thing which could be handed about from one nation to another, or hidden away for a time in some dark corner, And upon this amusing misconception he builds a wonderful theory, which, however, it is not worth while for any busy man to stop and refute. It is in a similar way, and owing to the same realistic tendency, that there has arisen the conception of such an entity as “The Will,” the existence of which modern psychology does not recognize any more than it recognizes the lapidity of stones or the ubication of points in space. Modern psychology is concerned only with the process of will, or volition, As Dr. Maudsley observes, “ it is not man’s function in life to think and feel only: his inner life he must express or utter in action of some kind —in word or deed. Receiving impressions from nature, of which he is a part, he reacts upon nature intelligently, modifying it in a variety of ways... As the spinal cord reacts to its impressions in excito-motor action, and as the Sensory centres react to their impressions in sensori-motor action, so, after the complex interworking and combinatiou 176 COSMIC PHILOSOPHY. (Pr. 11. of ideas in the hemispherical ganglia, there is in like manner a reaction or desire of determination of energy outwards, in accordance with the fundamental property of organic structure to seek what is beneficial and to shun what is hurtful to it. It is this property of tissue that gives the impulse which, when guided by intelligence, we call volition ; and it is the abstraction from the particular volitions which metaphysicians personify as the Will. ... Physiologically we cannot choose but reject the Will: volition we know, and will we know, but the Will, apart from particular acts of volition or will, we cannot know. To interpose such a metaphysical entity between reflection and action thereupon, would bring us logically to the necessity of interposing a similar entity between the stimulus to the spinal cord and its reaction. Thus instead of unravelling the complex by help of the more simple, we should obscure the simple by speculations concerning the complex.” As scientific in- quirers, ‘we have to deal with volition as a function of the supreme centres, following reflection, varying in quantity and quality as its cause varies, strengthened by education and exercise, enfeebled by disease, decaying with decay of structure, and always needing for its outward expression the educated agency of the subordinate motor centres. We have to deal with will, not as a single undecomposable faculty unaffected by bodily conditions, but as a result of organic changes in the supreme centres, affected as certainly and seriously by disorder of them as our motor faculties are by disorder of their centres. Loss of power of will is one of the earliest and most characteristic symptoms of mental . derangement; and whatever may have been thought in times past, we know well now that the loss is not the work of some unclean spirit that has laid its hands upon the Wili, but the direct effect of physical disease.” Volition i is, accurdingly, that transformation of feeling inte 1 Boly and Mind, pp. 22, 23. cH, XviI.] SOCIOLUGY AND FREE-WILL, | 177 action which is attended by a conscious comparison of im- pressions, and which involves nutritive changes in the cere- brum or cerebellum, or in both. As we saw in the pre- ceding chapter, the sequence of actions upon impressions is either reflex or instinctive, and in either case automatic, so long as the nervous energy liberated by the impression is instantly discharged through a completely permeable chan- ne! or set of channels. But in those higher organisms in which an immensely varied experience has established innu- merable complex systems of less permeable channels, there intervenes between the liberation of energy in the brain and its discharge upon the motor centres a period during which there is a tension between various nerve-currents, each seek- ing to discharge itself along the most permeable lines of transit. We saw also that this period of tension is a period of conscious deliberation, involving conscious reflection, and feelings of desire or aversion. And these views turned out to be justified by the fact that as soon as the frequent repeti- tion of any given set of experiences has rendered all the transit-lines involved in the case completely permeable, so that there is no longer any appreciable period of tension, then the acts once conscious and voluntary become invo- luntary and automatic. Now the state of consciousness called Desire is accom- panied by a nascent excitement of the nerve-fibres distributed upon the muscular apparatus whose activity is requisite for the attainment of the desired object. There is a tendency to go through with the movements, needful for realizing the desire; and this tendency, unless neutralized by an an- tagonist tendency, must end in action. In the language of dynamics, tension when not counteracted by opposing tension, must pass into wis viva. This passage of nervous tension into nervous vis viva constitutes volition, which may VOL. IL N 178 COSMIC PHILOSOPHY. (pr. 11. fcr piactical purposes be regarded indifferently as the final stage of emotion or as the initial stage of action. Passing from the case in which a single desire is operative let us briefly consider the special case of two conflicting desires, where the gratification of the one is incom- patible with that of the other. In this case, two groups of motor-nerves are nascently-excited. Here there are two opposite tensions, and the resulting action will depend on their comparative strength. If they exactly neutralize each other, as in the hypothetical case of the ass between the two bundles of hay, no volition will ensue. But in a complex aggregate, like the human or animal organism, such a state of equilibrium cannot be of long continuance. Sooner or later,—either from the greater vividness with which one of the desired objects is mentally realized, or from any one of a thousand other disturbing circumstances down to those of a purely physical nature,—one desire will become stronger than the other. And instantly thereupon, the surplus nervous tension remaining after the weaker desire is neutralized, will pass into nervous vis viva; or, in other words, volition will take place. The opposing tension need not, however, have desire for its concomitant. It may be furnished by the mere inertia of the nervo-muscular system ; as when a man, wishing to do some- thing which requires exertion, is too weary to do it. Weariness implies a diminution in the total amount of contractile force ; a state in which a tension greater than ordinary is obviously required for the initiation of muscular motion. Conversely, the originating tension need not always be supplied by desire, but may be consequent upon vivacity, which is the presence of a superfluous amount of vital energy ; as exemplified alike in the morning frolics of an infant, in the singing of birds, and in the gambols of a dog when released from his kennel. Casus as simple as those here treated occur no doubt with somparative infrequency., Usually’a great number of motives, cH, XVII.] SOCIOLOGY AND FREE-WILL, 179 indefinitely complex and variable in their mutual combina- tions and oppositions, are simultaneously operative. But however numerous or complicated the forces at work, from whatever source the motives to action or inaction arise, what- ever be the nature of the incentives to one kind of conduct or to some other kind, it is equally true that the result depends upon their comparative strength. Indeed, since forces can be measured only by their effects, to say that of two conflicting motives one is followed by volition, is to call that motive the stronger one. “ Our only evidence of excess of force is the movement it produces ”; and when the ancient engineer wished to ascertain the comparative power of a couple of catapults, he had no alternative but to see which would hurl its stone to the greater distance. To say explicitly that volition does not follow the strongest motive, is to say implicitly that motion does not always follow the line of least resistance; which is to deny the persistence of force. Volition being accordingly regarded as the process whereby feeling initiates action, it becomes evident that the term “free” is no more applicable to it than the termn “ copper- coloured.” As Mr. Bain observes; “ The designation ‘liberty of choice’ has no real meaning, except as denying extraneous interference. If I am interfered with by another person com- pelling me to act in one way, then it may be said, intel- ligibly enough, that I have not liberty of choice. But, as between the different motives of my own mind, there is no meaning in the use of the word ‘liberty.’ Various motives,— p-esent or prospective pleasures and pains,—concur in urging me to act. The result of the conflict shows that one group is stronger than another, and that is the whole case.”! Or, as M. Littré has still more forcibly reminded us, the term “liberty,” as applied to volition, means the power of obeying the strongest motive. When that power is interfered with, + Bain, The Emotions and the Will, 1st edit. p. 550. N 2 180 COSMIC PHILOSOPHY. (pr. m by paralysis or insanity, or the constraint exercised by other persons, then we may truly say that we are deprived of free- will and of responsibility. But so long as circumstances allow volition to follow the strongest motive, then we truly say that we are free and responsible for our actions. Thus the tables are completely turned, and much of the current disputation on this subject is reduced at once to unmeaning verbiage. The popular arguments in favour of “freedom” are seen to be as palpable cases of ignoratio elencht as are those daily urged against the development hypothesis. By a scientific definition of Will, the assertion. of freedom is set aside as irrelevant, leaving behind the assertion of non-causation. That this too is virtually disposed of by the same definition, scarcely needs pointing out. Yet, for the sake of still greater clearness, our present results may fitly be supplemented by a new class of considerations. That volitions differ from all other phenomena by their capability of occurring without any cause, is the opinion of the frée-will philosophers; and Mr. Smith, in criticizing the contrary opinion, remarks that “if comets formed their own future” (ze, were endowed with volition), “they would be rather embarrassing subjects of science.” Without at- tempting to decipher the vagaries in which these cosmical bodies might in such case take it upon themselves to in- dulge,! it will be enough for my present purpose to point out some of the shoals on which the free-will doctrine must land its defenders. If volitions arise without cause, it necessarily follows that we cannot infer from them the character of the antecedent states of feeling. If, therefore, a murder has been committed, we have @ priori no better reason for suspecting 1 In point of fact a comet does “form its own future” iu the same way that a man does. The state of a heavenly body at any given moment is a product, partly of the forces, molar and molecular, with which it was endowed at the preceding moment, and partly of the forces simultaneously exerted upon it by euvironing heavenly bodies. The case of human volition differs . from this in nothing save the number and complexity, and consequeat rela tive incalculableness, of the forces at work, CH. XVII.} SOCIOLOGY AND FREE-WILL. 181 the worst enemy than the best friend of the murdered man. If we see a man jump from a fourth-story window, we must beware of too hastily inferring his insanity, since he may be merely exercising his free-will ; the intense love of life im- planted in the human breast being, as it seems, unconnected with attempts at suicide or at self-preservation. We can thus frame no theory of human actions whatever. The countless empirical maxims of every-day life, the embodiment as they are of the inherited and organized sagacity of many genera- tions, become wholly incompetent to guide us; and nothing which any one may do, ought ever to occasion surprise. The mother may strangle her first-born child, the miser may cast his long-treasured gold into the sea, the sculptor may break in pieces his lately-finished statue, in the presence of no other feelings than those which before led them to cherish, to hoard, and to create. To state these conclusions is to refute their premise. Probably no detender of the doctrine of free-will could be induced to accept them, even to save the theorem with which they are inseparably wrapped-up. Yet the dilemma cannot be avoided. Volitions are either caused, or they are not. If they are not caused, an inexorable logic brings us to the absurdities just mentioned. If they are caused, the free-will doctrine is annihilated. No help is afforded by the gratuitous hypothesis that there is a connection between the act and the mative, which yet is not a causal connection. Such con- neciicn, if it exist, must be a case either of conditional invariable sequence, or of unconditional invariable sequence. On the first supposition, we have a case like the succession of day and night, in which both terms of the sequence are conditioned upon a third fact; so that here we do not escape causation. The second supposition is but an ass:2rtion of causation in other words. While to take refuge in the postulate that this assumed connection is a case of variable Jequence, is to affirm and deny connection in the same breath, 182 COSMIC PHILOSOPHY. (pr. 1 But it is said that consciousness declares the Will to be free; and therefore that any attempt to disprove its freedom by reasoning is suicidal, since all such reasoning must end by impugning the veracity of that consciousness on which its own data are ultimately based. An ingenious argument truly, the conclusion whereof would be more readily ad- mitted, if its premise were true. Consciousness, which is so confidently appealed to as establishing by its infallible verdict the doctrine of free-will, in fact says nothing about the matter. That volitions are uncaused, is a proposition altogether too indirect for consciousness to sit in judgment upon, and it can neither be proved nor disproved by simple introspection. It would have been equally appropriate for the ' medieval astronomer to appeal to conscivusness as testifying to the revolution of the sun about the earth. As Mr. Bain observes, “it is a great stretch of asseveration to call the construction of an enormous theory an act of consciousness so simple that we cannot make a slip in performing it.”? Consciousness tells us only that we will. By observation and experience—not by the simple and direct interrogation of consciousness—we know that, circumstances permitting, our volitions may be accomplished. With the exception, therefore, of those theological fatalists who assert that human actions are determined by an external constraining power, it is the universal opinion that men can voluntarily determine their own actions; and this is just what the much- abused testimony of consciousness amounts to. Thisis all that it means to anyone not mystified by metaphysics; the non- causation of volitions being a theorem so far from obvious to a great many men, that it requires considerable explana- “ion to make them understand it. By the testimony of consciousness, as thus interpreted, the assertors of the lawlessness of volition are not helped in the least. The question at issue between them and their opponents is, not 1 The Emotions and the Will, 1st edit. p. 563, oh ey OE ee ee oe AP on, XvII.] SOCIOLOGY AND FREE-W1LL. 183 whether the actions of men are normally free, but whether their freedom is consistent with their being caused. The assertors of “Free-Will” maintain that causation is inconsistent with liberty! The so-called necessarians assert that liberty ana causation are quite consistent with each other. To which we must now add, that it is not causation, but the absence thereof, which is as incompatible with liberty as it is with law. For the causationist, believing that volition invariably follows the stronger motive, endeavours to increase the relative strength of all those emotions whose outcome is virtuous and upright conduct, while he strives to weaken those feelings whose tendency is toward base and ignoble conduct. Knowing that by continual indulgence desire is rein- forced, while by constant repression it is enfeebled, he applies this knowledge to the control of his will and the discipline of his character. But on tl.e theory that volitions are causeless, all methods of self-discipline become of no avail. If they are powerless to influence action, it is of small practical importance whether noble and sympathetic or base and selfish motives are prevalent; and the moral distinction between them loses most of its significance. Why, asks Mr. Smith, “is a Philip II. more the subject of moral disapprobation than tlie plague?” Why, indeed, unless his atrocious crimes are to be interpreted as the necessary outgrowth of a character wherein good motives were impotent and bad motives all- powerful. Were volition self-determining, then similar acts 1 “The law of bondage throughout the universe is the law of cause and éffect. In the violation, then, of this law, true freedom must consist.” Ferrier, Lectures and Philosophical Remains, vol. ii. p. 255. One might expect such a remark as this trom Mr. Goldwin Smith, who speaks of being “bound by the chain of certain causation”; but from so acute a thinke as Prof. Ferrier, it is surprising. To adopt, in a somewhat altered sense, Kant’s happv illustration,—the spectacle of a bird denouncing as an encum- brance the air by which alone it is enabled to fly, would be a fitting parallel to the spectacle of those philosophers who decry that regularity of sequence through which alone has “freedom” any meaning. As Lessing long ago said, with well-bestowed contempt, “‘ Le beau privilége d’étre soumis & une uissance aveugle qui ne suit aucune régle! Zn seruitje moins le jowet du rd parce que ce hasard résiderait en moi?” 184 COSMIC PHILOSOPHY. (ex. 1. might have been committed by a Washington or a Borromeo, Obviously there would be little use in laboriously schooling our desires to virtue, if at any moment in spite thereof, some uncaused volition might bring forth from us a detestable deed. It is therefore not the doctrine of causation, but the so-called free-will doctrine, that, if true, would “ put an end to self-exertion,” and deprive us of every “rule of right action.” Since self-control, and therefore liberty, is impossible unless volition is determined by desire; it is the latter doctrine—not the former—which is really inconsistent with the assertion of human freedom, which takes from us the dignity of responsibility, ard makes man the sport ot a grotesque and purposeless chance. In truth, the immediate corollaries of the free-will doc- trine are so shocking not only to philosophy but to common- sense, that were not accurate thinking a somewhat rare phenomenon, it would be inexplicable how any credit should ever have been given to such a dogma. This is but one of the many instances, in which by the force of words alone, men have been held subject to chronic delusion. The libertarian doctrine has obtained currency because it has talked loudly of human freedom, with which nevertheless a brief analysis proves it to be incompatible. Substitute for the unmeaning phrase “ freedom of the Will,” the accurate phrase “lawlessness of volition,’ and the theory already looks less plausible. In place of the vague and ambiguous word “ necessity,” write the clear and definitely-connotative word “causation,” and the scientific theory at once loses its imaginary terrors, The titles with which the free-will doc- trine decorates itself, and those with which it brands its opponent, are alike “ question-begging epithets.” They serve to prejudge the point at issue, Not content with the overwhelming prestige which its name thus gives it, the free-will doctrine seeks to follow up its advantage by identifying its antagonist with Asiatic cu. Xvi1.] SOCIOLOGY AND FREE-WILL. 185 fatalism; a confusion of ideas like that under which Mr, Bounderby laboured, when unable to see the difference between giving workmen their just dues, and feeding them with turtle-soup out of a gold-lined spoon. To say that actions dependent on volition will take place whenever the essential conditions are present, and to say that they will take place even if the conditions are absent, are by free-will theorists held to be one and the same assertion!* Fatalism is, however, much more closely akin to their own doctrine, Each ignores causation ; each is incompatible with personal freedom; the only difference between them being that the one sets up Chance, while the other sets up Destiny, as the arbiter of human affairs. And while each doctrine is theo- retically held by large bodies of men, each in practice is habitually contradicted by its upholders. The defenders of free-will, who in practice are obliged to admit a certain con- aection between acts and motives, and the Arab fatalists, among whom the saying is current that “when Allah wills an event, he prepares the causes beforehand,” alike ex- emplify this. Though both agree in repudiating causation, both equally in their every-day maxims give evidence of an unconscious belief in its existence. Having identified the causation theory with fatalism, it Lecomes all the easier for its opponents to accuse it of deny- ing moral responsibility. Accordingly, when Mr. Buckle, following in the footsteps of Laplace, inferred from the regu- larity of the statistics of crime and suicide, marriages and uead-letters, that voluntary actions conferm to law ;? it was 1 “Tt is owing to the very general misconception of the nature of Law that there arises the misconception of Necessity ; the fact that events arrive irre- sistibly whenever their conditions are present, is confounded with the concep- tion that the events must arrive whether the conditions be present or not, being fatally predetermined. Necessity simply says that whatever is is, and will vary with varying conditions. Fatalism says that something must be ; and this something cannot be modified by any modification of the conditions.” —Lewes, Problems of Life and Mini, vol. i. p. 899. 2 Buckle, Civilization in Eng’and, vol. i. pp. 20—80; Laplace, Essai sur es Probabilités, p. 76. 186 COSMIC PHILOSOPHY. ; (pr. 1. proposed by one of his reviewers that state-governments should at once suspend judicial operations, and having ascertained from statistics the yearly number of murders, should forthwith hang a corresponding number of individuals, selected by lot from the community. To which suggestion the natural reply would have been, that if governments ever do adopt this singular course of administering justice, they will then be consistently acting on the belief that motives do not stand in a causal relation to volitions. If the volition can follow the weaker motive, the feelings which ordinarily deter from the commission of crime, need not be strength- ened by the fear of punishment.* Thus do all the favourite arguments in behalf of the free- will hypothesis recoil upon its defenders. To adopt from barbarian warfare, an ungraceful but expressive simile, they are like awkwardly-thrown boomerangs which wound the thrower. Attempting, as the free-will philosophers do, to destroy the science of history, they are compelled by an inexorable logic to pull down with it the cardinal principles of ethics, politics, and jurisprudence. Political economy, if rigidly dealt with on their theory, would fare little better ; and psychology would become chaotic jargon. That psy- chical actions, and volitions among them, conform to law, is the indispensable axiom of every science or philosophy which treats of the mind and its products, whether indi- 1 “The very reason for giving notice that we intend to punish certain acts, and for inflicting punishment if the acts be committed, is that we trust in the efficacy of the threat and the punishment as deterring motives. If the voli- tion of agents be not influenced by motives, the whole machinery of law becomes unavailing, and punishment a purposeless infliction of pain. In fact it is on that very ground that the madman is exempted from punishment ; his volition being presumed to be not capable of being acted upon by the deterring motive of legal sanction. The free agent, thus understood, is one who can neither feel himself accountable, nor be rendered accountable to or by others. It is only the necessary agent (the person whose volitions are de- termined by motives, and, in case of conflict, by the strongest desire or the strongest apprehension) that can be held really accountable, or can feel hime self to be so.”—Grete, Review of Mill’s Examination of Hamilton's Philo: sophy, p. 976 CH, XVI.)

He-who asserts the contrary, maintains “a form of the Manichean doctrine of two prin- ciples .... in which one principle, that of order, presides over the physical phenomena of the universe, and the other, that of disorder, over its moral phenomena.”! As I have already said, no middle ground can be taken. The denial of causation is the affirmation of chance, and “between the theory of Chance and the theory of Law, there can be no compromise, no reciprocity, no borrowing and lending.” To write history on any method furnished by the free-will doctrine, would be utterly impossible. Mr. Smith tells us that “finding at Rome a law to encourage tyrannicide, we are certain that there had been tyrants at Rome, though there is nothing approaching to historical evidence of the tyranny of Tarquin.” By drawing this inference he abandons his own principles, according to which the law in question might have originated without any cause except the self- determining will of some Roman legislator. And he is equally inconsistent in saying that “a nation may have to go through one stage of knowledge or civilization before it can reach another, but its going through either is still free.” If by this it is meant that a nation’s progress need not be due to constraint exercised over it by other nations, the state- ment is true, but it is one which no one has thought of dis- puting. But if it is meant that the latter of two successive stages of civilization is not caused by the former, the state- ment destroys itself. By admitting that “a nation may have to go through one stage of civilization before it can reach another,” Mr. Smith gives up his case and concedes all which has ever been claimed by those who would construct a science of history. If there is a definite order of sequence among the stages of civilization, that order may sooner or later be formulated, and to formulate that order is.to found sociology as a science. But if causation in history is denied, 3 W. Adam, Theories of History, p. 65. 188 COSMIC PHILOSOPHY, [pr wu. if each epoch is not determined by the preceding epoch, then the inference is inevitable that the French Revolution might have happened in the reign of Louis XI., or that the progress of Christianity might have been eastward instead of westward. Thus all conception of progress, as well as all conception of order, is at an end. Thus the vast domain of History, numbering among its component divisions the phe- nomena of Language, Art, Religion, and Government, the products of social activity as well as the phases of social progress, becomes an unruly chaos, a Tchu-va-Bohu, where event stumbles after event, and change jostles change, with- out sequence and without law. I think, therefore, we are quite justified in saying that, when stripped of the metaphysical jargon in which it is usually propounded, the question of free-will becomes an easy one to answer. Having laid the dust which metaphy- sicians have kicked up, we find our vision no longer obscured. From whatever scientific stand-point we contemplate the doctrine of the lawlessness of volition, we find that its plausibleness depends solely on tricks of language. The first ‘rick is the personification of Will as an entity distinct from all acts of volition; the second trick is the ascription to this entity of “freedom,” a word which is meaningless as applied to the process whereby feeling initiates action; and the third trick is the assumption that desires or motives are entities outside of a person, so that if his acts of volition were influenced by them he would be robbed of his freedom. Any- one, however, who is not misled by these verbal quibbles, and who bears in mind that a person, psychologically considered, is nothing more than the sum of his conscious states, will perceive at once that when the desires or aversions determine the volitional acts, it is the person himself who determines them. We have accordingly seen that, since liberty of choice means nothing if it does not mean the power to exert volition in the direction indicated by the strongest group of motives ; on. Xvit.] SOCIOLOGY AND FREE-WILL, 189 and since all control over character is impossible unless de- sires and volitions occur in a determinate order of sequence ; it is the doctrine of lawlessness and not the causationist doctrine which is incompatible with liberty and destructive of responsivility. The rhetoric which Mr. Goldwin Smith lavishes, on the strength of a set of misapplied phrases, might therefore be justly retorted upon him, on the strength of a psychologic analysis. And this, which is the conclusion of science, we have seen to be also the conclusion of common sense. Whatever may be our official theories, we all practi- cally ignore and discredit the doctrine that volition is lawless. Whatever voice of tradition we may be in the habit of echoing, we do equally, from the earliest to the latest day of our self-conscious existence, act and calculate upon the supposition that volition, alike in ourselves and in others, follows invariably the strongest motive. And upon this ineradicable belief are based all our methods of government, of education, and of self-discipline. Finally, in turning our attention to history, we have found that the aggregate of thoughts, desires, and volitions in any epoch is so manifestly dependent upon the aggregate of thoughts, desires, and volitions in the preceding epoch, that even the assertors of the lawlessness of volition are forced to commit logical suicide by recognizing the sequence. Thus, whether we contemplate volitions themselves, or compare their effects, whether we resort to the testimony of psychology or to the testimony of history, we are equally compelled to admit that Law is coex- tensive with all orders of phenomena and with every species of change, It is hardly creditable to the character of the present age for scientific enlightenment that such a statement should need «o be made, or that twenty-six pages of critical argument should be required to illustrate it. To many this chapter will no doubt seem much like an elaborate attempt to prove the truth of the multiplication table. Nevertheless where such 190 _ COSMIC PHILOSOPHY. [pr. 11. a blinding metaphysical dust has been raised, a few drops of the cold water of common-sense may be not only harmless but useful. Having thus done somewhat to clear the air, we may next proceed to point out the way in which social changes conform to the Law of Evolution, CHAPTER XVIIL THE EVOLUTION OF SOCIETY, Any attempt to discover the laws to which social changes conform must run great risk of being frustrated by the mere immensity of the mass of details which the investigator strives to arrange in orderly sequence. Seemingly number- less as are the phenomena dealt with by the physical sciences, they bear no proportion, either in multitude or in variety, to the facts upon which the student of sociology must build his scientific theorems. Facts concerning man in his physical relations to soil, climate, food, and the configuration of the earth, blend with facts concerning the intellectual and moral relations of men to each other and to the aspects of nature by which they are surrounded, making up a problem of such manifold complexity that it may well have long been deemed incapable of satisfactory solution. The fit ground for wonder is, indeed, not that we are as yet unable to arrive at accurate prevision amid such a diversified throng of phenomena, but that, considering the meagreness of our knowledge in many other departments, we should have been able to detect any uniformity whatever in human affairs, and having detected .f, to explain it upon trustworthy scientific principles. There is but one way to conduct such an intricate investiga- tion securely to its final issue; and that is, to make extensive 192 COSMIC PHILOSOPBY. [er. 11 use of elimination as it is employed in the simpler sciences. | “If without any previous investigation of the properties of terrestrial matter, Newton had proceeded at once to study the dynamics of the universe, and after years spent with the telescope in ascertaining the distances, sizes, times of revolu- tion, inclinations of axes, forms of orbits, perturbations, etc., of the celestial bodies, had set himself to tabulate this accumulated mass of observations, and to educe from them the fundamental laws of planetary and stellar equilibrium, he might have cogitated to all eternity without arriving at a result.” This lucid illustration, which I have cited from the introduction to Mr. Spencer’s “Social Statics,” suggests the proper method of approaching the investigation of complex phenomena. Minor perturbing elements must for a time be left out of consideration, just as the inequalities of motion resulting from the mutual attractions of the planets were at first passed over in the search for the general formula of gravitation. The discussion of endless minute historical details must be reserved until the law of social changes has been deduced from the more constant phenomena, and is ready for inductive verification. A law wide enough to form a basis for sociology must needs be eminently abstract, and can be found only by contemplating the most general and prominent characteristics of social changes. The prime requisite of the formula of which we are in quest is that it should accurately designate such changes under their leading aspect. Now by far the most obvious and constant characteristic common to a vast number of social changes is that they are changes from a worse to a better state of things,—that they constitute phases of Progress. It is not asserted that human history has in all times and places been the history of progress ; it is not denied that at various times and in many places it has been the history of retrogression; but attention is called to the fact-—made trite by long familiarity, yet none OH. XVILI. | THE EVOLUTION OF SOCIET.. 193 the less habitually misconceived—that progress has been on the whole the most constant and prominent feature of the history of a considerable and important portion of mankind. Around this cardinal fact have clustered, as I just hinted, many serious misconceptions. The illustrious thinkers of the last century, who endeavoured to study human history from a scientific point of view, were unconsciously led into an error from which contemporary writers have not as yet entirely freed themselves. The followers of Turgot and Condorcet were prone to regard progress as something neces- sary and universal, They attempted to account for it, much as Lamarck tried to explain organic development, as the continuous and ubiquitous manifestation of an occult, in- herent tendency toward perfection. Subsequent literature exhibits many traces of this metaphysical conception. Thus Dr. Whately, in his edition of Archbishop King’s discourses, asserts that “civilization is the natural state of man, since he has evidently a natural tendency toward it.” Upon which it has been aptly remarked that, “by a parity of reasoning, old age is the natural state of man, since he has evidently a natural tendency towards it.” Indeed, as this comparison is intended to show, it is difficult to use such expressions as “natural state” and “natural tendency” without becoming involved in a confusion of ideas. And to ascribe progress to an inherent tendency, without taking into account the complex set of conditions amid which alone that tendency can be realized, is to give us an empty formula instead of a scientific explanation. Whether the individual will die young or reach old age, and whether the community will remain barbarous or become civilized, depends, to a great extent, upon environing circumstances; and no theory of progress can have any value which omits the consideration of this fact. Mr. William Adam labours under the confusion of ideas here signalized, when he finds fault with Sir G. C. Lewis for upholding the doctrine of progress while admitting VOL. IL Oo 194 COSMIC PHILOSOPHY. (pr. 1, that certain races have never advanced in civilization. For this, Mr. Adam accuses him of virtually dividing mankind into two differently-constituted races, of which the one possesses, while the other lacks, the inherent tendency toward perfection! He might as well maintain that because we admit that certain men are stunted, while others grow tall, we divide mankind into two differently-constituted races, of which the one possesses while the other lacks, the inherent tendency toward increase in size. Closely allied to this fallacy is that which associates lateness in time with com- pleteness in development, and requires us to assume that nowhere at any time has there been a temporary retrogression. Thus Mr. Goldwin Smith appears to be confused by the impression that the temporary decline in the moral tone of English society after the Restoration of Charles IL., is a fact inconsistent with the doctrine of a general progress. And Mr. Mansel still more preposterously declares that on the theory of progression we ought to regard the polytheism of imperial Rome as a higher form of religion than the earlier Hebrew worship of Jehovah. While another form of the same confusion is to be seen in the attempts which writers imbued with the conception of progress often make, to coax the annals of the past into affirming the uninterrupted advance of civilization. These examples show how vaguely the doctrine of progress has hitherto been apprehended. The fallacy of supposing civilization to have proceeded serially, or uniformly, or in consequence of any universal tendency, is nearly akin to the fallacy of classifying the animal kingdom in a series of ascend- ing groups,—a fruitful source of delusion, which it was Cuvier's great merit to have steadily avoided. The theological habit of viewimg progressiveness as a divine gift to man,’ and the 2 W. Adam, Theories of History, p. 87. * “It is impossible for mere savages to civilize themselves. . . . Come — sequently men must at some period have received the rudiments of civilization tH. XVIII.) THE EVOLUTION OF SOCIETY, 195 metaphysical habit of regarding it as a necessary attribute of humanity, are equally unsound and equally fraught with error. Until more accurate conceptions are acquired, no secure advance can be made toward discerning the true order of social changes. Far from being necessary and universal, progress has been in an eminent degree contingent and partial. Its career has been frequently interrupted by periods of stagnation or declension, and wherever it has gone on, it has been forwarded, not by an inexplicable ten- dency or nisus, but by a concurrence of favourable con- ditions, external and internal. We must remember more- over, as Sir Henry Maine reminds us,’ that the communities which have attained to a conspicuous degree of civilization constitute a numerical minority of mankind. Contempora- neous with the rapidly advancing nations of Europe exist the sluggish nations of Asia, and the almost stationary tribes of Africa and Polynesia. “Better fifty years of Europe than a cycle of Cathay.” So irregular, indeed, has been the march of civilization, that most stages of progress may be made the subject of ocular investigation at the present day. In the science of history, therefore, old “means not old in chronology, but in structure: that is most archaic which lies nearest to the beginning of human progress considered as a development, and that is most modern which is farthest removed from that beginning.” ? Nevertheless, in spite of the fact that the career of progress has been neither universal nor unbroken, it remains entirely true that the law of progress, when discovered, will be found to be the law of history. The great fact to be explained is from a superhuman instructor.” (!) Whately’s Rhetoric, p. 94.

And when we have formulated the character of progress, and the conditions essential to it, we have the key to the history of the stationary as well as of the progressive nations. When we are able to show why the latter have advanced, the same general principle will enable us to show why the former have not advanced. Though in biogeny we habitually view the process of natural selection as the process whereby higher organisms are slowly originated, the principle loses none of its importance because sundry species from time to time suffer deterioration, or remain stationary, or become extinct. When we know how it is that some species advance, we know how it is that other species do not advance. So, in the science of language, which is equally with sociogeny a science of development—being, indeed, neither more nor less than a quite special province of sociogeny—we rightly consider the main problem solved when we have explained the process of phonetic integration, by which languages ascend from the primary, through the secondary, to the tertiary stage of structure. It matters not that Chinese remains to this day a primary language, and that the numerical majority of languages have not yet become tertiary by completely fusing together the component roots of their words. The process by which languages pass from a lower stage to a higher remains none the less the fundamental phenomenon to be investigated, and when we have generalized the conditions under which this process takes place, we can xplain its absence as well as its presence. Now the case is the same with progress in society, that it is with progress. in language or in organic life. Whether manifested or not manifested in any particular community, progress is still the all-important phenomenon to be investigated. It is the one grand phenomenon, to explain the presence and the absence of which, is to explain the phenomena of history Just as the study of the languages which have advanced furnishes us the key for understanding those which have oh lat Ll ly Ek #H. XVIII] THE EVOLUTION OF SOCIETY. 197 not advanced, ‘so the study of the progressive communities furnishes us, as we shall see, the law of history ; a law which, in its most general expression, covers the phenomena pre- sented by the non-progressive communities likewise. Ccmte was therefore right in restricting the main current of his inquiry to the course of that civilization which began on the eastern shores of the Mediterranean, and has extended over Europe and a portion of America, The same plan will be pursued in the present chapter. Although incidental con- firmation will be sought in the history of the stationary communities, our main problem will be to formulate the law of progress from a comparison of the phenomena presented by the progressive communities. But before we can fairly enter upon our task, it will be desirable for us to note the Factors of Progress with which we shall chiefly have to deal. The prime factors in social progress are the Community and its Environment. The environment of a community comprises all the circumstances, adjacent or remote, to which the community may be in any way obliged to conform its actions. It comprises not only the climate of the country, its soil, its flora and fauna, its perpendicular elevation, its relation to mountain-chains, the length of its coast-line, the character of its scenery, and its geographical position with reference to other countries ; but it includes also the ideas, feelings, customs, and observances of past times, so far as they are preserved by literature, traditions, or monuments; _as well as foreign contemporary manners and opinions, so far as they are known and regarded by the community in ques- tion. Thus defined, the environment may be very limited or very extensive. The environment of an Eskimo tribe consists of the physical circumstances of Labrador, of adjoining tribes, of a few traders or travellers, and of the sum-total of the traditions received from ancestral Eskimos. These make up the sum of the conditions affecting the social existence of 198 COSMIC PHILOSOPHY. fpr. the Eskimos. The environment of the United States, on the other hand, while it comprises the physical conditions of the North American continent, comprises also all contemporary nations with whom we have intercourse, and all the organized tradition—political and ethical, scientific and religious— which we possess in common with all the other commu nities whose civilization originated in the Roman Empire. The significance of this increase of size and diversity in the environment will be explained presently. Bearing in mind this definition of a social environment— which I believe carries with it its own justification—let us briefly notice the error committed by those writers who would fain interpret all the most important social phenomena as due, solely. or chiefly, to physical causes. This is an error fre- quently committed by physiologists who try their hand at the investigation of social affairs, and who attempt to treat sociology as if it were a mere branch of biology. But this is not the case. As we have seen psychology to be an off- shoot from biology, specialized by the introduction of in quiries concerning the relations of the percipient mind to it environment; we must similarly regard sociology as an off- shoot from psychology, specialized by the introduction of inquiries concerning the relations of many percipient and emotionally-incited minds to each other and to their common environment. As in biogeny all attempts to discover the law of organic development failed utterly so long as the relations of the organism to physical environing agencies were alone studied, and succeeded only when Mr, Darwin took into account the relations of organisms to each other; so still more inevitably in sociogeny must all our efforts fail so long as we consider merely the physiologic relations of a commu- nity to the country in which it dwells, and refuse to recognize the extent to which communities influence each other by means that are purely intellectual or moral. Doubtless the character of the physical environment is of importance, more cH. XVIII.] THE EVOLUTION OF SOCIETY. 199 especially, perhaps, in the earlier stages of civilization. No doubt civilization will first arise, other things equal, in a locality where food and shelter can be obtained with a medium amount of exertion; where nature is neither too niggard nor too lavish in the bestowal of her favours. No doubt there is a physical significance in the fact that civiliza- tion began, not in barren Siberia, or in luxuriant Brazil, but in countries like Egypt and Mesopotamia, which were neither so barren as io starve, nor so luxuriant as to spoil, the labourer. No doubt the Greeks owed much to the extent of their coast-line. No doubt—above all—the Mediterranean is _ justly sacred to the student of history as partly the civilizer of the peoples who upon its waves first courted adventure, and conducted commerce, and imparted to each other cosmo- politan sympathies which could never have been evoked but for some such intercourse, All this may be granted. But as civilization advances, the organized experience of past gene- rations becomes to a greater and greater extent the all- important factor of progress. As Comte expresses it, in one of his profoundest aphorisms, the empire of the dead over the living increases from age to age. If we contemplate, from a lofty historical point of view, the relative importance of the factors in the environment of our United States, I believe we shall be forced to conclude that the victory of the Greeks at Marathon, the conquest of Gaul by Cesar, the founding of Christianity, the defeat of Attila at Chalons and of the Arabs at Tours, the advent of the Normans in England, the ecclesiastic reforms of Hildebrand, the Crusades, the revolt of Luther, the overthrow of the Spanish Armada, and the achievements of scientific inquirers from Archimedes to Faraday, have influenced and are influencing our social con- ition to a far greater extent than the direction of the Rocky Mountains, or the position of the Great Lakes or the course of the Gulf Stream. Or if we inquire why the Spaniards are still so superstitious and bigoted, I believe we shall find 200 COSMIC PHILOSOPHY. [pr. 11. little enlightenment in the fact that Spain is peculiarly subject to earthquakes, but much enlightenment in the fact that for eight centuries Spain was the arena of a life- and-death struggle between orthodox Christians and Moorish unbelievers. i The mention of Spain and earthquakes brings me to Mr. Buckle, a writer of marked ability, who, though he did not explicitly countenance the error I am here criticizing, was nevertheless sometimes betrayed into committing it, as may be seen from the following passage :—“The Arabs in their own country have, owing to the extreme aridity of their soil, always been a rude and uncultivated people; for in their case, as in all others, great ignorance is the fruit of great poverty. But in the seventh century they conquered Persia; in the eighth century they conquered the best part of Spain; in the ninth century they conquered the Punjab, and eventually nearly the whole of India. Scarcely were they established in their fresh settlements, when their character seemed to undergo a great change. They who in their original land were little else than roving savages, were now for the first ‘ime able to accumulate wealth, and, therefore, for the first ‘ime did they make some progress in the arts of civilization. Yn Arabia they had been a mere race of wandering shepherds; in their new abodes they became the founders of mighty empires, — they built cities, endowed schools, collected libraries ; and the traces of their power are still to be seen at Cordova, at Bagdad, and at Delhi.”1 To exhibit the utter superficiality of this explanation, we have only to ask two questions. First, if the Arabs became civilized only because they exchanged their native deserts for Spain, Persia and India, why did not the same hold true of the Turks, when they exchanged their barren steppes for the rich empire of Constantinople? Though they have held for four cen- turies what is perhaps the finest geographical position on the 1 History of Civilization, vol. i. p. 42 Ps ne a ig a eh cH. XVIII.] THE EVOLUTION OF SOCIETY. 201 earth’s surface, the Turks have never directly aided the progress of civilization. Secondly, how was it that the Arabs ever came to leave their native deserts and to conquer the region between the Pyrenees and the Ganges? Was it because of a geologic convulsion? Was it because the soil, the climate, the food, or the general aspect of nature, had undergone any sudden change? One need not be a profound student of history to see the absurdity of such a suggestion. It was because their minds had been greatly wrought upon by new ideas ; because their conceptions of life, its duties, its aims, its possibilities, had been revolutionized by the genius of Mohammed. The whole phenomenon requires a psychological, not a physical, explanation. The environment in our problem must, therefore, not only include psychical as well as physical factors, but the former are immeasurably the more important factors, and as civiliza- tion/advances their relative importance steadily increases. Bearing in mind these preliminary explanations, let us now address ourselves to the problem of social evolution, applying to the solution of it sundry biological principles established in previous chapters. We have first to observe that itis a corollary from the law of use and disuse, and the kindred biologic laws which sum up the processes of direct and indirect equilibration, that the fundamental characteristic of social progress is the continuous weakening of selfishness and the continuous strengthening of sympathy. Or—to use a mor convenient and somewhat more accurate expression suggested by Comte—it is a gradual supplanting of egoism by altruism. In the course ux our inquiry into the causes of organic evolution; it was shown that all the processes cooperating in the development of higher from lower forms of life, are in the widest and deepest sense processes of equilibration. The all-important truth was there demonstrated, that the progress of life on the earth has been the continuous equilibra- 1 See above, chapters xii. and xiii, 202 COSMIC PHILOSOPHY. . {Pr. 11. tion of the organism with its environment. In the mainten- ance of such an equilibrium life has been shown to consist. Accordingly, as we have seen, if the environment is suddenly and violently altered, the organism perishes; but when it is altered slowly, the organism slowly adapts itself to it. If the adaptation is not completed within a single generation, nevertheless a sufficient number of generations will com- plete it, just as the children and grandchildren of an emi- grant become more and more thoroughly acclimated to their new home. ? It is now to be shown that civilization is a slow process of breeding, of adaptation, of acclimatization—mental and moral, as well as physical,—of equilibration between the Community and the Environment. From age to age the environment is slowly but incessantly changing, and to its gradual changes the human race, embodied in communities, is continually adapting itself. As just observed, I am not referring to the physical environment alone; for in dealing with society we have to take into the account those psycho- logical factors which have been shown to be by far the most considerable of all. Leaving out of the aecount all minor considerations of climate, food, or other physical circum- stances, and looking at the psychological factors alone, we must admit that the environment is slowly but constantly changing. Every city that is built, every generalization that is reached, every invention that is made, every new principle of action that is suggested, alters in some degree the social environment,—alters the sum-total of external relations to which the community must adjust itself by instituting new internal relations. The entire organized experience of each generation, so far as it is perpetuated by literature or oral tradition, adds an item to the environment of the next succeeding generation; so that the sum-total of the circumstances to which each generation is required to conform itself, is somewhat different from the sum-total of 2 Fore aes be i i Si ra BO is 0B, Xvit1.) THE EVOLUTION OF SOCIETY, 203 circumstances to which the immediately preceding genera- tion was required to conform itself. Thus the community, by the inevitable results of its own psychical activity, is . gontinually modifying the environment; and to the environ- ment, as thus continually modified, the community must reciprocally conform itself. Now in the primitive, isolated, savage condition of man- kind, what was the environment of each family or petty tribe, and what kind of emotional activity was it fitted to awaken? The unanimous testimony of scientific expiorers, and others who have carefully studied the primitive phases of society, leaves us in little doubt as to this question. As Mr. M’Lennan concisely expresses it, “ The state of hostility is the normal state of the race in early times.”! The environ- ment of each little tribe is a congeries of neighbouring hostile tribes; and the necessity of escaping captivity or death involves continual readiness for warfare, and the continual manifestation of the entire class of warlike unsocial passions. While, on the other hand, the tribe is so small and homo- geneous, that the opportunity for the exercise of sympathetic and social feelings is confined chiefly to the conjugal and parental relations. Nevertheless in the exercise of these feelings in these relations are contained the germs of all subsequent social progress. While without the limited sphere of the tribe all is hatred, revenge, and desire to domineer, within the limits of the tribe there is room for the rudimentary display of such feelings as loyalty, gratitude, equity, family affection, personal friendship, and regard for the claims of others. Since these feelings can be exercised only within family or tribal limits, it follows that the sphere for their exercise is relatively small; while as the hostile or egoistic feelings are conformed to the whole environment outside of the tribe, it follows that the sphere for their exercise is large. Hence, in this primitive state of society, the egoistic feelings, being 2 Primitive Marriage, p. 184. 204 _ COSMIC PHILOSOPHY. | [pr. 11, oftenest called into play in the habitual occupations of life, will be most active and will overbalance the altruistic feel- ings. While, on the other hand, as the kindlier sympathies are but nascent, even the altruistic feelings, such as they are, will be strongly tinged with egoism. The highest emotion attainable will be clannishness, and the highest rule of duty will be that which enjoins loyalty to the tribal patriarch, This is actually found to be the emotional and ethical condi- tion of primitively organized communities, wherever they have been attentively studied by competent observers. Such, for example, has been the state of things existing from time immemorial among the American Indians, among the Poly- nesians, and among the Arabs of the desert; and these aspects of clan-society, in a somewhat later stage, among the Scottish Highlanders, are well pourtrayed in several of the Waverley Novels. : Now what is it that chiefly determines the slow develop- ment of the altruistic feelings and the gradual atrophy of the egoistic feelings? Obviously it is the growth of the commu- nity in size and complexity,—the gradual enlargement of the area over which the altruistic feelings extend, and the gradual increase in the number of social situations which demand the exercise of those feelings. These conditions are partly fulfilled when the tribal community grows to a vast size, remaining structurally a tribe with a patriarchal head,—~—as was the case in ancient Egypt, Assyria, Persia and India, and as is still the case in China. But they are still better fulfilled when the community increases in the complexity of its internal relations, and, instead of remaining a tribe, hecomes a federation of civic bodies, as in ancient Grecce, or a single great civic body, uniting various tribal elements, as in ancient Rome. In each of these cases, the increased power of’ self- protection renders warfare less necessary and frequent, and the partial supplanting of the primitive predatory life by the occupations of agriculture and trade besins to make men sae Se ee ee cH, XVIt1.] THE EVOLUTION OF SOCIETY. 205 more and more dependent on one another over a wider and wider area, and to create a whole class of interests to which warfare and destructiveness are more and more inimical. And in the latter case, where the community assumes a civic character, the rise of a genuine political life begins to make men operate on each other by indirect compulsion, or by persuasion, rather than by direct and brutal compulsion ; and _ the highest attainable ethical feeling is no longer clannishness fo) fo) : but patriotism, in the exalted sense in which that word wai understood by the Greeks and Romans. Note also that under the influence of this high ethical feeling, even military life oses its primitive purely egoistic character, and becomes a school of self-discipline and self-sacrifice, nourishing in no slight degree the altruistic feelings. If we compare the cam- paigns of Marathon and Thermopylai with the expedition of a band of Highlanders in execution of a blood-feud, or with the excursion of a party of Red Indians on the war- path, we shall find no difficulty in realizing the force of these considerations. But, like other phenomena in nature, our ethical Shelitins are not sharply marked off from each other. There is a selfish as well as a sympathetic side to patriotism (under- standing the word always as the Greeks and Romans under- stood it.) At the one extreme, patriotism is akin to clannishness ; at the other extreme, it becomes so wide as to resemble cosmopolitanism. As long as the purely civic structure of society lasted, the clannish element was dis- tinctly present in patriotism. Greek history, after the expulsion of the Persians, is the history of the struggle between the higher and the lower patriotism,—between the two feelings. eaeiven to the Greeks as Pan-Hellenism and Autonomism, represented respectively by Athens and by the Doric communities. The mournful history of Thuky- dides tells us how autonomism won the day, entailing the moral and political failure of Greek civilization, 208 | COSMIC PHILOSOPHY. (rr. 1. _ But when Rome had extended her beneficent sway over all the precincts of the Mediterranean, uniting communities hitherto autononious and hostile by common interests of culture and of commerce, and bringing aggressive warfare to an end in the Pax Romana, then there became possible a cosmo< politan spirit, a Christian feeling, which regarded all men as legally and ethically equal,—equal before the Emperor, and equal before God. To trace the slow growth of this feeling in the annals of Roman law and of Stoic philosophy, and to observe its culmination in the genesis of Christianity, is to obtain the key to Roman history. _. But great political changes were necessary before Rome could carry to the end its great work,—partly because it had increased in size so much faster than it increased in structure. It crushed autonomism too rapidly. It developed imperialism at tlie éxpense of nationality. And hence the time at last arrived when the mutual cohesion of its provinces became too slight to withstand those barbaric assaults from without, which—as we should be careful to remember—had all along been intermittently attempted from the days of Brennus to those of Alaric. For a time, European society seemed likely to disintegrate into a set of tribal communities. But the old Empire had done its work too thoroughly for that. Roman principles, embodied in the Catholie Church, and in the renovated Empire of Charles the Great, exerted an organizing power which prevailed over the spirit of elannish isolation, and by effecting the grand series of compromises which we vaguely designate as the feudal system, laid the basis of _ modern society. If now wé examine the ethical circumstances of that vast modern fabric which has been reared upon material supplied 1 Of coursé it is Hot méant to imply that other elements were not at work in the genesis of Christianity.

Son, Ee ot ee CH, XVIII.) THE EVOLUTION OF SOCIETY, 207 in the older days of Rome—and which owes so much of its permanent character to the labours of the great Catholic and Imperial statesmen of the Middle Ages—we shall find that the process here described has been continually going on. For the primitive normal state of warfare there has been eradually substituted a normal state of peace. While in primitive times the interests of men were supposed to coin- cide only throughout the limited area of a petty clan, they are now seen to coincide throughout vast areas, and the railway, the steamship, and the telegraph are daily bringing communities into closer union, and, as George Eliot well expresses it, “making self-interest a duct for sympathy.” The spirit of Christianity, first rendered possible by Roman cosmopolitanism, has made, and is ever making, wider and deeper conquests as civilization advances, By the primitive savage moral duties were imperfectly recognized, but only within the limits of the clan. By the Greek the ethical code was enlarged, but it was a code not applicable to bar- barians. The medieval Christian had a.still longer list of duties owed by him to all mankind, his brethren in the sight of God; and to the ancient conception of justice thus materially widened, he added, in elementary shape, the con- ception of benevolence or the “enthusiasm of humanity ;” but the familiar maxim that “no faith need be kept with heretics” shows that even to his conception of duty there were practical limits narrower than would now be admitted. The modern, on the other hand, recognizes that he owes cer- tain duties to all men with whom he may be brought into contact, not because they are his kindred, or his neighbours, ur his countrymen, or his fellow-Christians, but because they are his fellow-men. Such is cur ethical standard, however imperfectly conformed to; and neither ancient nor medieval nad such an ethical standard.

The modern type is the man of mild personality, shunning the appearance of self-assertion, slow to anger, patient of contradiction, mindful of the feelings of those about him, unwilling to “make trouble.” Such is the con- trast between the typical ancient and the typical modern; and it implies a prodigious alteration in the dominant ethical feelings of the progressive portion of our race. This change, as we now see, has been wrought by the slow but incessant modification of the social environment to which each generation of men has had to conform its actions. The altruistic feelings, finding at each successive epoch a wider scope for action, have become gradually strengthened by use; while the egoistic feelings, being less and less imperatively called into play, have become gradually weakened by disuse. And this change in the environment we. perceive to have been wrought by the continuous growth of the community in size and complexity. Where, as among stationary tribes of savages, there has been no such growth, there the moral type of the primeval man is still to be found; and where, as among the stationary communities of Asia, there has been growth in size without corresponding growth in complexity, there the moral type is intermediate between that of the barbarian and that of the inheritor of Roman civilization. Thus the progress of society is a mighty process of equili- bration or adjustment, in the course of which men’s rules o action and emotional incentives to action become ever more and more perfectly fitted to the requirements arising from the circumstance of their aggregation into communities. Here we have arrived at a rudimentary conception of the law of social progress, so far as it can be obtained from a > comprehensive historical induction, aided and verified by deduction from a few fundamental truths of biology. The ae oct S On, XVIII.) THE EVOLUTION OF SOCIETY. 209 foregoing discussion has brought out one point of funda- mental importance, in which the development of social life agrees with the development of organic life: both are con- tinuous processes of adjustment or equilibration. But in all this there 1s nothing more than might have been anticipated. Since the phenomena of society are really but the phe- nomena of life, specialized by the addition of new groups of circumstances ; we must expect to find that the law of social evolution will be identical with the law of organic evolution, save only that it will require an all-important additional clause to express the results of the action of the superadded circumstances. Let us then seek to ascertain definitely,— first, in what respects the two kinds of evolution agree, and secondly, in what respects they differ, ' In the first place the evolution of society, no less than the evolution of life, conforms to that universal law of evolution discovered by Mr. Spencer, and illustrated at length in earlier chapters. The brief survey just taken shows us that social progress consists primarily in the integration of small and simple communities into larger communities that are of higher and higher orders of composition ; and in the more and more complete subordination of the psychical forces which tend tc maiutain isolation, to the psychical forces which tend to main- tain aggregation. In these respects the prime features of social progress are the prime features of evolution in general. In the second place, the progress of society exhibits those secondary features of differentiation and integration which evolution universally exhibits. The advance from indefinite homogeneity to definite heterogeneity in structure and function is a leading characteristic of social progress. On considering primitive societies, we find them affected by no gauses of heterogeneity except those resulting from the astablishment of the various family relationships. As Sir denry Maine has shown, in early times the family and not the individual was the social unit. In the absence of any- VOL. II, P 210 COSMIC PHILOSOPHY. {pr 1 thing like national or even civic organization, each family chief was a monarch in miniature, uniting in his own person the functions of king, priest, judge, and parliament; yet he was scarcely less a digger and hewer than his subject children, wives, and brethren. Commercially, it is needless to say, all primitive communities are homogeneous. In any barbarous tribe the number of different employments is very limited, and such as there are may be undertaken indiscriminately — by everyone. Every man is his own butcher and baker, his own tailor and carpenter, his own smith, and his own weapon maker. Now the progress of such a society toward a civi- lized condition begins with the differentiation and integration of productive occupations. That each specialization of labour entails increased efficiency of production, which reacting brings out still greater specialization, is known to every tyro in political eccnomy. Nor is it less obvious that, with the advance of civilization, labour has been steadily increasing in coherent heterogeneity, not only with regard to its division among different sets of mutually-dependent labourers, but also with regard to its processes, and even its instruments, The distinguishing characteristic of modern machinery, as compared with the rude tools of the Middle Ages or the clumsy apparatus of the ancients, is its definite heterogeneity. The contrast between the steam-engine of to-day and the pulleys, screws, and levers of a thousand years ago assures us that the growing complexity of the objects which labour aims at is paralleled by the growing complexity of the modes of. attaining them. Turning to government, we see that by dif- ferentiation in the primeval community some families acquired supreme power, while others sank, though in different degrees, to the rank of subjects. The integration of allied families into tribes, and of adjacent tribes into nations, as well as that kind of integration exhibited at a later date in the closely-knit diplomatic inter-relations of different countries, are marked steps in social progress. Next may be mentioned the differs om, xvitt.] THE EVOLUTION OF SOCIETY. 211 entiation of the governing power into the civil and the eccle- siastical; while by the side of these ceremonial government grows up insensibly as a third power, regulating the minor details of social intercourse none the less potently because not embodied in statutes and edicts. Comparing the priests and augurs of antiquity with the dignitaries of the medizval Church, the much greater heterogeneity of the latter system becomes manifest. Civil government likewise has become differentiated into executive, legislative, and judicial. Exe- eutive government has been divided into many branches, and diversely in different nations. A comparison of the Athenian popular government with the representative systems o/ the present day shows that the legislative function has no more than any of the others preserved its original homogeneity. While the contrast between the Aula Regis of the Norman kings and the courts of common law, equity, and admiralty, county courts, queen’s courts, state courts, and federal courts,—which are lineally descended from it, tells us the same story concerning the judicial power. Nor should it be forgotten that the steady expansion of legal systems, to meet the exigencies which civilization renders daily more complex, is an advance from relatively indefinite humogeneity to relatively definite heterogeneity. Obviously, however, our task is not completed when we have pointed out this general coincidence between the development of society and the development of life. Nor can the universal law here illustrated be the special law of social progress for which we are seeking. By reason of its very comprehensiveness, the law of universal evolution cannot be regarded as supplying the precise kind of in- formation we desire concerning the relations of social to wganic phenomena. By its aid we have found it possible to interpret not only the development of life, intelligence, and society, but also the genesis of planetary systems and he evolution of the earth. It is therefore the law not only P 2 212 COSMIC PHILOSOPHY. (er. 11, of social, psychical, and vital changes, but also of inorganic changes. Underlying all the sciences of genesis, and fusing them into one grand science of cosmogony, it utters no truth concerning organic or social development which is not equally true of aJl development. Thus while it is indeed, in the deepest sense, the ultimate law to which organic and super- organic changes conforin, it is silent respecting the differential dhaxnotéristica by which these changes are distinguished from inorganic changes. Already in treating of the evolution of life we saw that the ultimate and general formula needed to be supplemented by a derivative and special formula, which should describe organic development in terms inapplicable to inorganic phenomena. And this formula we found in the detinition of life as the continuous adjustment of inner to outer relations, upon which also was afterwards based our entire theory of the evolution of intelligence. ‘Now the historic survey into which we were led a moment ago, while inquiring into the progress of moral feelings, showed us that, in this respect also, the evolution of society agrees with the evolution of life in general. The progress of a community, as of an organism, is a process of adaptation, —a continuous establishment of inner relations in con- formity to outer relations. If we contemplate material civi- lization under its widest aspect, we discover its legitimate aim to be the attainment and maintenance of an equilibrium between the wants of men and the outward means of satis- fying them. And while approaching this goal, society is ever acquiring in its economic structure both greater hetero- geneity dnd greater specialization. It is not only that agri- culture, manufactures, commerce, legislation, the acts of the ruler, the judge, and the physician, have since ancient times grown immeasurably multiform, both in their processes and in their appliances; butit is also that this specialization has resulted in the greatly increased ability of society to adapt :tself to the emergencies by which it is ever beset. The CH. XVIII.] THE EVOLUTION OF SOCIETY, 213 history of scientific progress is in like manner the history of an advance from a Jess complete toward a more complete correspondence between the order of our conceptions and the order of phenomena, Truath—the end of all honest and successful research—is attained when subjective relations are adjusted to objective relations. And what is the con- summation of moral progress but the thorough adaptation of the desires of each individual to the requirements arising from the coexistent desires of all neighbouring individuals ? Thus the phenomena of social and of organic progress are seen to correspond to a degree not contemplated by those thinkers who, from Plato to Hobbes, have instituted a com- parison between them. The dominant characteristics of all life are those in which social and individual life agree. Let us now examine more closely the relations between the Community and the Environment. From the twofold circumstance that life is high according as the organism is heterogeneous, and also according as it is adjusted to sur- rounding conditions, may be derived the corollary that the heterogeneity of the environment is the chief proximate deter- mining cause of social progress. Thus we may understand why civilization advances so much more rapidly in modern than it did in ancient times. As Sir Charles Lyell observes; “We see in our own times that the rate of progress in the arts and sciences proceeds in a geometrical ratio as know- ledge increases, and so, when we carry back our retrospect into the past, we must be prepared to find the signs of re- _tardation augmenting in a like geometrical ratio; so that the progress of a thousand years at a remote period may cor- respond to that of a century in modern times, and in ages still more remote Man would more and more resemble tbe brutes in that attribute which causes one generation exactly to imitate in all its ways the generation which preceded it.”* That the process is here the same in social and in 2 See above, p. 72. * Antiquity of Man, p. 377. 214 COSMIC PHILOSOPHY. {P. 0. organic life, Sir Charles Lyell already suspects; for he else- where observes that the lower the place of organi¢ beings “in a graduated scale, or the simpler their structure, the more persistent are they in form and organization. In what- ever manner the changes have been brought about, the rate of change is greater where the grade oi organization is higher.” And this fact results from the more complex rela- tions of the higher beings to their environment. Applying these considerations to history, it will be seen that, owing to the political isolation of ancient communities, the hetero- geneity of their environments must have been inconsiderable. Holding little intercourse with each other, and accommo- dating their deeds and opinions mostly to the conditions existing at home, their progress was usually feeble and halt- ing. Owing to the enormous heterogeneity of the environ- ment to which modern communities are forced to adjust themselves, progress in later ages has been far more rapid and far more stable than of old. The physical well-being of an ancient Greek was not enhanced by an invention made in China, nor could his philosophy derive useful hints from theories propounded in India. But in these days searcely anything can happen in one part of our planet which does not speedily affect every other part. The physical environ- ment of a modern European extends over a great part of the earth’s surface, and his psychical environment is scarcely limited in time or space. ‘His welfare is not unfrequently affected by accidents occurring at the antipodes, while his plans for the coming year are often shaped with conscious or unconscious reference to events which happened centuries ago. That the rapid and permanent character of modern progress is in great measure due to this circumstance, will be denied by no one. And thus is explained the wonderful eivilizing effect of various events which have from time to time brought together distant sections of mankind; among which it will be sufficient merely to name the campaigns of 3H. XVIU.] THE EVOLUTION OF SOCIETY. 215 Alexander, the spread of Roman dominion, the Arabian con- quests, the Crusades, and the voyages of Columbus, Magellan, and De Gama. The invention of printing, increasing the rapidity and the frequency with which the thoughts of various minds are brought into contact, offers another illus- tration ; and in a similar way is to be explained the civilizing agency of railroads and telegraphs. Comparing these deductions with the historical survey of ethical development above taken, we arrive at a set oi mutually harmonious conclusions. We see that the process of intellectual and moral adaptation which constitutes social progress is determined by the steadily increasing hetero- geneity of the social environment. And we see that this increased heterogeneity of the environment is caused by the integration or growing interdependence of communities that were originally isolated. We have now to examine this process of integration somewhat more in detail. By insti- tuting a novel comparison between the processes of organic and of social life, we shall be led directly to the special law of progress for which we are seeking. Observe first that the living beings which are lowest, or next to the lowest, in the scale of organization—as, for example, the protococeus and the amceba—are nothing but simple cells. It has heen shown, by Mr. Spencer, that progress in morphological composition, both in the animal and in the vegetable kingdoms, consists primarily in the union of these simpie cells into aggregates of higher and higher orders of complexity. Now in the study of social evolution we are met by precisely similar phenomena. Let us consider what is implied by the conclusions at which Sir Henry Maine has arrived, in his profound treatise on “Ancient Law,” by an elaborate inquiry into early ideas of property, contract, and testamentary succession, and into primitive criminal legislation. “Society in ancient times,” says Sir Henry Maine, “ was not what it is assumed to be 216 COSMIC PHILOSOPHY. — (re. 1. at present, a collection of individuals. In fact, and in the view of the men who composed it, it was an aggregation of The contrast may be most forcibly expressed ‘dy saying that the wnit of an ancient society was the family, of a modern society the individual.” But originally the ~ family-government excluded not only individual indepen- dence, but also state supremacy. The sole government actual or possible was that exercised by the male head of a family-group. By slow stages various family-groups closely akin in blood appear to have become integrated into tribes or clans, community of descent being still the only con- ceivable bond which could hold together a number of indi- viduals in the same political aggregate. Ata later stage the limits of the tribe were further enlarged by the impor- tant legal fiction of “ adoption,” or the pretence that newly- added members were descended from some conspicuous common ancestor of the tribe. Vestiges of a time when there were no aggregations of men more extensive than the tribal community thus constituted, and when there was no sovereign authority save that exercised by the head of the tribe, may be found in every part of the world,? and among totally-savage races this state of things still continues. Now we shall find something more than an instructive analogy in the comparison of the primitive family-group to a unicellular organism, for such a comparison will enable us to realize that in social and in organic evolution the process of integra- tion has been substantially the same. The first well-marked stage in coalescence is the formation of the tribe or clan, 1 Ancient Law, p. 126. 2 “The yévos of Athens, the gens of Rome, the mark or gemeinde of the Teutonic nations, the village community of the East . . . the Irish clan, are all essentially the same thing "—Freeman, Comparative Politics, p. 102. See, among other authorities, Volney’s View of the United States, p. 397 ; Phillipp on Jurisprudence, p. 207; Charles Comte, Traité de Législation, liv. iii, chap. 28; Grote, History of Greece, vol. iii., pp. 49—69 ; Gibbon (Paris edit.), vol. iii., p. 245; Vico, Scienza Nuova, Opere, tom. iv., pp. 23, 85, 40; Aristotle Zh.

Gall. vi. 22, 23. cH, XVIII.} THE EVOLUTION OF SOUIETY. 217 which may be compared to those lowly organisms made up by. the union of ameeba-like units with but little specializa- tion of structure or function. At this stage social organi- zation is but one step removed from that absolute and ferocious anarchy which characterizes the non-social life of brutes. “ Mistrust, jealousy, secret ambushes, and implacable vengeances ” characterize the mutnal relations of these social “ agoregates of the first order.” Hostility is the rule, and peace the exception. The repulsive forces are stronger and the cohesive forces weaker than at any subsequent period. As we have seen above, the selfish impulses which tend to maintain savage isolation are as yet unchecked save by instinctive loyalty within the tribal limits. The coalescence of such tribes into civic communities is the formation. of social “aggregates of the second order.” For a long time these higher aggregates retain conspicuous traces of their mode of composition, as in Greece and Rome,} until increasing social heterogeneity obliterates the original lines of demarcation; while new divisions spring up, result- ing from the integration of like parts, as is seen in the guilds of medisval Europe, and still better in the localization of industries which marks the present time. The coalescence of civic-and_tribal_ communities into the. nation—an “ aggregate of the.third-.order ”—is well exem- plified in the history of France, which, from a disorderly collection of independent baronies, has passed by well- defined transitions into a perfectly integral nation. The attainment of this stage is indispensable to a career of permanent progress. As hinted above, the premature overthrow of the Hellenic political system is to be attributed 1 The structure of the Amphiktyonic union shows “that the system of cities with which we are so familiar in Grecian history grew out cf an earlier system of tribes.” Freeman, Comparative Politics, p. 88. Further evidence, in abundance, may be found in the succeeding pages of that excellent book, veh reads, from beginning to end, almost like a commentary upon this pter. : 218 COSMIC PHILOSOPHY. fer. m tu its very incomplete integration. An aggregate of the national type was in process of formation by the extensive coalescence of maritime cities under the leadership of Athens, when the Peloponnesian war intervened, vindicating the superiority of selfish autonomy, and showing by its result that the civilizing spirit of nationality was as yet too feeble to prevail. It was first under Roman dominion that national agere- gation and the feeling of national solidarity began to be brought to something like completeness. By absorbing nearly all the petty communities then existing within the limits of the Mediterranean world, and by gradually extend- ing to their members the privileges of citizenship, Rome succeeded in dealing to the passion for autonomy a blow from which it has never recovered; while the enormous extent of the Empire, and its ethnic heterogeneity, imparted to the national spirit thus evoked, a cosmopolitan character destined to be of prodigious service to civilization. The influence of these circumstances upon the attitude of Chris- tianity I have already alluded to, and it cannot be too strongly insisted upon. No human mind could have even conceived, much less have carried into execution, the idea of a universal religion, if the antique state of social isolation had not previously been brovght to a close in universal empire. If Christianity had appeated four centuries earlier than it did, it would, like Buddhism, have assumed the garb of a local religious reformation. Or if it could have aimed at anything higher and more comprehensive than this, its preaching would have fallen upon ears not ready to receive it. All the Oriental enthusiasm, all the Hellenic subtlety, of Panl, could have effected nothing, had he visited Athens in the days of Plato and Diogenes. But the cosmopolitan element in Roman civilization was just that which Chris- tianity most readily assimilated, and which it intensified by setting up a new principle of common action in place of the — e, en ee es OH. XVIIL.] THE EVOLUTION OF SOCIETY. 219 primeval principle of community of race. From this hippy concurrence of circumstances there” was formed, upon the ruins of Paganism, that religious organization which alone, of all churches that have existed, has earned the glorious name of Catholic. Disgusted at some of her high-handed proceedings in later times, Protestant historians haye too generally forgotten that the Roman Church, by co-ordinating the most vigorous and progressive elements of ancient life, prepared the way both for the ubiquity and for the per- manence of modern civilization. Had the ecclesiastical system of the Empire perished, along with the breaking up of its political system; had there been really that wreck of ancient institutions in the fifth century which was formerly supposed to have occurred, until Mr. Bryce and Mr. Freeman dispelled the gross error; it is difficult to see how medieval European history could have been politically anything more than a repetition of Grecian history, save only in the extent of its geographical range. Whoever is disposed to doubt so emphatic an assertion will do well duly to ponder the fact that the newly-arriving Teutonic subjects of the Empire (who would, in such case, have come as foreign conquerors) had not advanced beyond the stage of tribal organization. On their further aggregation into rural and civic bodies, the autonomous spirit would have acquired an ascendency which it might well have taken another more fortunate Athenian federation, or another all-absorbing Roman domination, thoroughly to destroy. Even as it was, it required all the immense power of the Church, unflinch- ingly exercised through many generations, to prevent Euro- pean society from disintegrating into a mere collection of mutually repelling tribal communities, But the Church not only preserved the best social results of Roman dominion, by hastening the consolidation of each embryonic nation- ality; it also, by its peculiar position as common arbiter between the different states thus arising, assisted in the 220 COSMIC PHILOSOPHY. pr formation of a new social aggregate of a yet higher order. The modern system of independent nationalities held in virtual federation—not by international codes, but by the possession of guiding principles of conduct more or less heartily reverenced by all—is chiefly the work of the Roman Church. Here, finally, we have reached a system whose structure bears in the highest degree the marks of perma- nence. It is sustained by the ever-deepening sentiments of cosmopolitan philanthropy and universal justice,—the most cohesive cf social forces, as the spirit of local selfish- ness was the most disruptive. Here it might seem that we have obtained all the data requisite for enunciating our law of social progress. But something is still wanting. Our law of progress, if now enunciated, would be too general. It would cover alike the phenomena of social and of organie life. In both there is an advance from indeterminate uniformity to determinate multiformity ; in both there is a continuous adaptation of the organism or the community to its environment; and in both there is a continuous integration, entailing an advance from incoherence to coherence of structure. We must now start in search of that all-important clause which shall express the essential difference between organic and social progress, ’ In the ancient family-community, as delineated by Sir Henry Maine, the separate existence of the individuals was almost submerged and lost in the corporate existence of the ageregate. Personal freedom was entirely unrecognized. To family duties all individual rights were subjected. By a tie, religious no less than political, the members of the family were all held in allegiance to its oldest male representative, The father might abandon his son in infancy, and when grown up might sell him as a slave, or put him to death for disobedience. And the wife was to an equal extent in the power of her husband, to whom she legally stood in the relation of a daughter, so that marriage was but the ex- +. CH. XVIII.] THE EVOLUTION OF SOCIETY, 221 change of one form of servitude for another. No transfer of property was valid, unless the persons conducting it swore in the name of some ancestor,—dead ages ago, it might be; for so absolute was the authority of the paterfamilias that it could not be conceived as departing from him at death, but must be exercised by him, through the medium of prescrip- tive ceremoniai, over whole generations to come. Nothing, in short, was regulated by contract, but everything was deter- mined by status." And this is the fact which irretrievably demolishes Rousseau’s theory that social aggregation is due to @ primitive compact. That theory is merely an illegitimate attempt to explain an ancient phenomenon by causes which have had only a modern existence.2, The member of a pri- mitive tribal community had no conception of contract; what he was born to do, belonged to his status; and that he must do. The prevalence of this state of things in the empires of the East is chief among many converging proofs that those nations are nothing but immense tribes, or aggregates of the . first order. With the rise of higher aggregates, such as states, civic or imperial, this sinking of the individual in the corporate existence still for some time continued. The rights and duties of the individual were still unrecognized, save in so far as they followed froin the status in which he happened to be placed. In republican Rome, and in the Hellenic commu- nities, the welfare of the citizen was universally postponed to the welfare of the state. But circumstances too compli- cated to be here detailed, of which the chief symptom was the iicreasing importance assigned by Roman jurisprudence to contracts, resulted, at an advanced period of the empire, 1 This term is well defined by Heineccius :—“ Status est qualitas cujus ratione homines diverso jure utuntur. .. Aliojure utitur liber homo ; alio servus ; alio civis ; alio peregrinus.” Recitationes, lib. i. tit. 3. 2 See the discussion of the doctrine in Austin, Province of Jurisprudence, pp. 331—371 ; Kant, Rechtslehre, Th. ii., Abschn, L3 Stahl, Philosuphde des Rechts, ii, 142; Maine, Ancient Law, chap. iv 4 222 COSMIC PHILOSOPHY, [Pr. 11, in the more or less complete recognition of individual rights and obligations. On the rise of the feudal system, the rela- tions of vassal to suzerain were, through the influence of Roman conceptions, extensively regulated by contract; and it is in this respect that the feudal institutions are most widely distinguished “from the unadulterated usages of pri- mitive races.”* It was, I believe, mainly owing to this that the integration of feudal lordships into nations was accom- panied by the enlargement of individual liberty to a much greater extent than the integration of ancient clans, gentes, and phratries into civic communities. The Roman Church also aided in promoting the freedom of individuals, as well as in facilitating the consolidation of states. By the more or less strict enforcement of clerical celibacy, it maintained in the midst of hereditary aristocracy a comparatively demo- cratic organization, where advancement largely depended upon moral excellence or intellectual ability. And preserv- ing, by the same admirable institution, its independence of feudal patronage, it was often enabled successfully to inter- pose between the tyranny of kings and the helplessness of subjects. To ecclesiastical celibacy, more than to almost any other assignable institution, we owe our emancipation from ancient patriarchal conceptions of social duty. The develop- ment of industry, crossing in various ways the antique divisions of society, has contributed to the same result; until, in modern times, the primitive mode of organization is almost entirely effaced, leaving but few barely traceable vestiges. Individual rights and obligations, from being no- thing, have come to be all in all. While originally the indi- vidual was thought to exist only for the sake of the state, the state is now regarded as existing only for the sake of the individual. | It will thus be seen that the very same process, which has resulted in the formation of social aggregates of a higher and 1 Maine, op. cit. p. 365. on, XVIII] THE EVOLUTION OF SOCIETY. 223 higher order, has also resulted in the more and more complete subordination of the requirements of the aggregate to the requirements of the individual. And be it further noticed, that the relative strength of the altruistic feelings which maintain the stability of the highest social aggregation, main- tains also to the fullest extent the independence of its inu- vidual members; while the relative strength of the egoistic feelings which in early times prevented the exisvence of any higher organization than the family or tribe, was also in- compatible with individual freedom of action, Now this is precisely the reverse of the state of things which we find in organic evolution. In organic development, the individual life of the parts is more and more submerged in the cor- porate life of the whole. In social development, corporate life is more and more subordinated to individual life. The highest organic life is that in which the units have the least possible freedom. The highest social life is that in which the units have the greatest possible freedom. This feature of social evolution is most conveniently described by Schelling’s term individuation, which is employed in a kindred sense both in Mr. Spencer’s and in other modern works on biology. Thus we have at last reached the conclusion in quest of which we set out. Supplementing our previous results, according to which organic and social evolution were seen to agree, by our present result, according to which they are seen to differ, we obtain a formula for social evolution which may be regarded as fundamentally accurate. We obtain the Law of Progress, which may be provisionally stated as follows :— “ The Evolution of Society is a continuous establishment of psychical relations within the Community, in conformity to physical and psychical relations arising in the Environment ; during which, both the Community and the Environment pass from @ state of relatively indefinite, incoherent homogeneity to a state of relatively definite, coherent heterogeneity; and during 224 COSMIC PHILOSOPHY, ~— (er. 11. which, the constituent Units of the Community become ever more distinctly individuated.” In the next chapter I shall proceed to show how this ex- ceedingly general and technical formula includes and justifies whatever is defensible in sundry less abstract generalizations, expressed in more popular language, by Comte and Buckle. We shall be called upon to pass in review certain phases of social evolution, and to criticize, with the aid of the theorems now at our disposal, the claims of Comte to be regarded as the founder of sociology. CHAPTER XIX, ILLUSTRATIONS AND CRITICISMS, THE discussion contained in the foregoing chapter has shown to what a notable extent the phenomena of social evolution may be expressed, with the strictest accuracy, by formulas originally invented to describe the evolution of life in general, Let us briefly review the results which we heve already obtained. _ First, we saw that social as well as orga’e evolution consists in the continuous adaptation of the community, or organism, to the environment. Or, expressing the same thing in other words, social progress is a continuous establishment of inner relations in conformity to outer relations. Secondly, we saw that in the course of this adeptation the community, like the organism, continually incresses in definite heterogeneity, through successive differentiations and integrations. Thirdly, we saw that in the community, as in the orgavism, the increase in internal heterogeneity is determined by the continuous increase of heterogeneity in the environment. Fourthly, we saw that the increase of heterogeneity in the environment is determined by the successive integration of communities into more and more complex and coherent ageregates. And this law also holds of organic progress. VOL, II. Q 226 COSMIC PHILOSOPHY. (pr. 1 These four generalizations, expressing the points in which social and organic development coincide, were summed up in the two first clauses of our law of progress. They are imme- diate corollaries of the law of universal evolution and of the definition of life as adjustment. They are not to be under- stood as mere expressions of striking analogies. They are to be understood as implying that the evolution of life and the evolution of society are, to a certain extent and in the most abstract sense, identical processes. Such a con- clusion, indeed, became inevitable the moment we were brought to admit that the phenomena of society constitute but a specialized division of the phenomena of psychical life. Nevertheless it would be a grave error to infer, from this necessary coincidence in development, that a community is nothing more than a kind of organism, as Plato imagined in his “ Republic,” and Hobbes in his “ Leviathan.” When we go so far as to compare the metropolis of a community to the heart of an organism, its roads to blood-vessels, its cir- culating commodities to circulating nutritive materials, its money to blood-corpuscles, its channels for transmitting intelligence to nerve-axes, and the individuals of which it is composed to physiologic units; we are instituting a series of analogies, which are no doubt of considerable value in the study both of history and of political economy. In his essay on the “Social Organism,” Mr. Spencer has traced a great number of such analogies, which are no less instructive than curious, but they are after all analogies and not homologies, So when M. Littré points out that the study of political economy stands in the same relation to the science of sociology as the study of the nutritive functions to the science of biology, he reveals an analogy of great philoso- phical value. But we nevertheless feel that there is a wide distinction between an organism and a community, which it would be absurd to ignore; and Hobbes’s conception of society as a vast Leviathan strikes us as grotesque. AE ee en, x1x.] ILLUSTRATIONS AND CRITICISMS, 227 This insuperable distinction is the fact that in a community the psychical life is all in the parts, while in an organism the psychical life is all in the whole. The living units of society “do not and cannot lose individual consciousness,” while “the community as a whole has no corporate consciousness.” “The corporate life must here be subservient to the lives of the parts; instead of the lives of the parts being sub- servient to the corporate life.” The historical induction at the close of the preceding chapter showed us that such has been the case. While during the advance toward greater heterogeneity and coherence, the original lines of demarcation between communities have been ever becoming effaced as the communities have become integrated into higher and higher ageregates, we saw that as a part of the very same process the individualities of the members of society have been ever increasing in definiteness and ever acquiring a wider scope for activity. And we saw that this process not only has ever gone on, but must continue to go on; since, by the law of use and disuse, the sympathetic or social feelings must con- tinue to grow at the expense of the selfish or anti-social feelings ; and since this slow emotional modification, which makes possible the higher integration of society, ensures also the higher individuation of its members. “ Progress, there- fore, is not an accident, but a necessity. Instead of civiliza- tion being artificial, it is a part of nature; all of a piece with the development of the embryo or the unfolding of a flower. The modifications mankind have undergone, and are still undergoing, result from a law underlying the whole organic creation ; and provided the human race continues, and the constitution of things remains the same, those modifications must end in completeness.”* As surely as the astronomer can predict the future state of the heavens, the sociologist can foresee that the process of adaptation must go on until 1 Spencer’s Essays, 2nd series, p. 154, * Spencer, Social Statics, p. 65. Q 2 228 COSMIC PHILOSOPHY. [rr. 1. in a remote future it comes to an end in rroximate equili- brium. The increasing interdependence of human interests must eventually go far to realize the dream of the philosophic poet, of a Parliament of Man, a Federation of the World, “When the kindly earth shall slumber, lapt in universal law,” and when the desires of each individual shall be in proximate equilibrium with the means of satisfying them and with the simultaneous desires of all surrounding individuals. Such a state implies at once the highest possible individuation and the highest possible integration among the units of the com- munity; and it is the ideal goal of intellectual and moral progress, Thus the fundamental law of progress, as formulated at the close of the last chapter, contains all the provisions requisite in such a formula. It describes, in a single grand generaliza- tion, all the phenomena of social evolution, both in so far as they result from the general laws of life, and in so far as they result from the operation of circumstances peculiar to the ageregation of intelligent organisms in a community. And it includes and justifies all the minor generalizations which may be reached by a direct induction from historical pheno- mena solely. This law of progress we find to be exceedingly abstract: it expresses a general truth quite completely disengaged from the incidents of particular cases. Such, as we were led to anti- cipate, must be the character of a law which generalizes a vast number of complex phenomena. A formula which is to include in one expression phenomena so different as the rise of Christianity and the invention of the steam-engine must needs be eminently abstract. To attempt to make it concrete, so as to appeal directly to the historical imagina- tion, would be to deprive it of its universality, to increase its power of expressing some one set of phenomena by render- ing it powerless to express some other equally important set, Se oem ee 510 On ee ae . = Soa cu, x1x.] ILLUSTRATIONS AND CRITICISMS. 229 This consideration explains the manifest failure of all the attempts which have been made to determine the general law of progress by a simple historical induction. Take, for ex- ample, the two crude generalizations which pretty nearly sum up the philosophy of history as it is contained in the work of Mr. Buckle; that “scepticism” is uniformly favour- able to progress, while the “protective spirit ” (or, the spirit of over-legislation) is uniformly detrimental to it. These, in the first place, are generalizations drawn from a peculiar and temporary phase of society and illegitimately extended to all phases of society ; and, in the second place, even so far as they go, they have but a limited applicability,—expressing at best certain aspects of intellectual and industrial progress, but leaving quite out of sight, that slow moral evolution which underlies the whole. Whatever of truth is contained in these statements is also contained in the formula which I am here expounding, and is much more accurately expressed in the terms of that formula. Scepticism, for instance, in the best sense of the word, is the attitude of mind which is ‘caused by the perception that certain inner psychical rela- tions—say, a given set of beliefs or institutions—have ceased to be adapted to outer relations. The medieval conception of the world, as presented in Dante’s treatise on “The Monarchy,” was very closely adapted both to the know- ledge and to the social needs of the time. The conception of man as the centre of a universe made solely for his use and behoof, with a sun to give him light by day and a moon and stars to give him light by night, with an Em- peror and a Pope divinely appointed to rule him in this life, and an Autocrat in heaven uniting in himself the functions of these two, and ruling nature according to his arbitrary will; this conception, I say, was in harmony both with the best science and with the most urgent social requirements of the time, and the fact of its long duration shows how profound was the harmony, While this state of 230 COSMIC PHILOSOPHY, [PT. IL ‘things lasted, there was but little room for scepticism. But after a while the psychical environment had so far altered as to be out of balance with this conception of the world. The Copernican revolution unseated Man from his throne in the centre of the universe, and advancing physical generali- zation cast discredit upon the theory of providential govern- ment, and so arose the long line of “infidels” from Bruno and Varini to Voltaire and Diderot. While, on the other hand, the increasing power of monarchy, especially in France, gradually undermined the moral independence of the Papacy, converting it from an upholder of equity and a friend of the people into an unscrupulous ally of regal usurpation and iniquity; and thus arose the Great Schism, followed by the Protestant revolt and the grand democratic movement which culminated in the French Revolution. Now what is all this infidel rebellion against dogma and democratic rebellion against authority, but the intellectual and moral turbulence caused by the growing cenviction that the psychical relations comprised in the authorized conception of the world were out of balance with the new aggregate of relations formed by the discoveries of science and the altered requirements of social existence? And this painful attitude of the mind, prompting men to fresh investigation of the order of nature and to new social re-arrangements, is the stimulus to a new and closer adaptation. Such is the function of scepticism in the community, and such also is its function in the individual. A person, for instance, is educated in an environment of Presbyterian theology, accepting without question all the doctrines of Calvinism. By and by his environment enlarges. Facts in science or in history, methods of induction, canons of criti- cism present themselves to his mind as things irreconcilable _ with his old creed. Hence painful doubt, entailing efforts to escape by modifying the creed to suit new mental exigencies. Hence eager study and further enlargement of cu. x1x.} ILLUSTRATIONS AND CRITICISMS. 231 the environment, causing fresh disturbance of equilibrium > and renewed doubt resulting in further adaptation. And so the process continues until, if the person in question be sufficiently earnest and sufficiently fortunate, the environ- ment enlarges so far as to comprehend the most advanced science of the day, and the process of adaptation goes on until an approximate equilibrium is attained between the order of conceptions and the order of phenomena, and scepticism, having discharged its function, exists no longer, save in so far as it may be said to survive in the engrained habit of weighing evidence and testing one’s hypotheses. Now to say that scepticism is one of the causes of progress is to make a historical induction which is valuable as far as it goes; but it is at best an empirical generalization. To make it a scientific law, we need to express the function of scepticism in terms of some formula which covers all the phenomena of progress. And who does not see that in so expressing it we are obtaining a far more definite and ac- curate and serviceable notion than when we merely state vaguely that scepticism is a cause of progress? Just so with the statement that the protective spirit is a hindrance to progress. By the colloquial phrase “ protective spirit,” Mr. Buckle means the control, or at least the undue control, of the community over its individual members, Now in estimating the effect of this circumstance upon pro- gress, everything depends upon the precise amount of such control which we are to regard as excessive. But this varies with each epoch of civilization. What would now be in- tolerable despotism was once needful restraint. You cannot have a constitutional democracy of Vandals or Moguls. So long as men’s altruistic feelings are not powerful enough to make them spontaneously respect the claims of their fellows, the only force which can make society hold together is that hero-worship which enjoins implicit obedience to the head of the tribe or state. But, as we have already seen, the 233 COSMIC PHILOSOPHY, [pr. 1 steady growth of altruism at the expense of egoism, which renders possible a more complete social aggregation, renders possible also a more complete development of individual liberty. So that what in one age is a needful control exercised by the community over its members becomes in the next age an undue control. All this is expressed in the law of progress, as here formulated; but it is not expressed, with any approach to accuracy, in the crude statement that the protective spirit is an obstacle to civilization. Indeed the longer we study this general formula, the more we shall be convinced that it includes and justifies all sound inductions which can be derived from a survey of historical phenomena. As we apply it to the facts of history one after another, we shall see ever more clearly that its very abstract- ness is its excellence, and that the initial difficulty in thoroughly realizing its import arises from its very fulness of meaning. And we shall become ever more deeply impressed with the belief that no amount of mere historic induction can give us a universally applicable law of social progress, unless our results be deductively interpreted as corollaries from the general laws of life. We are now in a position to examine the claims of Comte to be regarded as the founder of sociology. And first let us note that a law of social progress answering so many require- ments as are met by the law above expounded could not have been obtained earlier than the present generation or even than the present decade. To conceive of sociogeny as a specialized branch of psy- chogeny, itself a specialized branch of biogeny, was not pos- sible until a general science of genesis had been at least partially instituted. The very idea of a science of genesis as applied to organic phenomena was not elaborated until the appearance of Von Baer’s great treatise in 1829, And the conception was then altogether too novel to be worked into the web of philosophy which Comte was weav- cu. x1x.] ILLUSTRATIONS AND CRITICISMS. 233 ing. Considering how, throughout the latter part of his life, he steadfastly refrained from the study of contemporary scien- tific literature, I do not think it likely that Comte ever became aware of the growing prominence of this conception of genesis; and if he had become aware of it he would doubtless have scornfully repudiated it, as he repudiated almost every new conception which was distinctly in advance of the limited scientific knowledge of 1830. The knowledge which Comte was not prepared to utilize at that date, he was certainly not in a condition to utilize at any later period of his life. It was in 1857, the year of Comte’s death, that Mr. Spencer, in an essay entitled “ Progress: its Law and Cause,” first definitely extended the law of organic develop- ment to historic phenomena; although he had ever since 1851 been visibly working toward that result, and had in 1855 reached that grand generalization of the development of both life and intelligence, regarded as processes of adjust- ment, which underlies the law of social progress here ex- pounded. It was this splendid series of researches, culmi- nating in the announcement of the universal law of evolution, in 1861, which supplied a new basis for all the sciences which treat of genesis, and rendered possible the discovery of the special, laws of sociogeny. And finally, in 1861, the further clue to these special laws was given by Sir Henry Maine, whose immortal treatise on “ Ancient Law” threw an entirely new light upon the primitive structure of society, and demonstrated—what before could only have been sur- mised—that human society, as earliest organized, consisted of a congeries of tribal communities by the integration of which have arisen the various orders of states and federations known to history. When, therefore, we inquire whether Comte did or did not create a science of sociology, we need not be surprised if it appears that he did not create such a science. For in socio- logy, even more than in any other science, the prime requisite 234 COSMIC PHILOSOPHY. [pr. 1 is tv formulate the law of evolution—in this case, the crder of sequence of historic events from epoch to epoch. So far as a science of society could be founded upon purely statical considerations, the work had already been performed; by Adam Smith, as regards political economy, by Bentham, as regards jurisprudence, and by both these great thinkers, as re- gards ethics. But ethics, jurisprudence, and political economy, put together, do not make up a science of society, as Comte clearly saw. For in sociology the historical element—the question whence we started and whither we are bound—is the element which takes precedence of all others. Even ethics, jurisprudence, and political economy cannot be placed upon a truly rational basis until we understand the order of intellectual ‘and moral change from epoch to epoch. To understand the “tendencies of the age” is an indispensable pre-requisite for sound sociological thinking as well as for sound political acting. Thus that portion of sociology which treats of genesis is, relatively to the whole science, even more important than the corresponding portions of biology and psychology. In biology pure and simple, we can, as we have seen, obtain a tolerably complete notion of the order of changes in the organism, with but occasional reference to the comparatively stable and unchanging environment. In psy- chology we have to take the environment into account at every step; but unless we are studying the quite special problem of the growth of the mental faculties, we do not need to refer to a definite and persistent succession of changes in the environment. But in sociology we cannot work in this way. As M. Littré has well pointed out, when we come to study humanity we are met by a new phenomenon un- known in biology or in psychology pure and simple. That new phenomenon is Tradition, or the bequeathing of all its organized intellectual and moral experience by each genera- tion to its successor. Here for the first time we have an environment which is rapidly changing in a definite order cu. x1x.] ILLUSTRATIONS AND CRITICISMS. o& of sequence, and changing by the very activity of the com- munity itself. The organized experience of each generation becomes a part of the environment of its successor, and since in each successive age “the empire of the dead over the living increases,” the environment of each generation consists to a greater and greater extent of the sum-total of traditions bequeathed hy all past generations. Hence we cannot hope scientifically to comprehend the simplest feature in any given state of the community without reference to ancestral states. The religious phenomena of the present day, for example, cannot be understood without previous knowledge of the whole history of Christianity, and indeed of human speculative thought since men began to be aware of the universe about them. Our political organization can be scientifically interpreted only as the offspring of ances- tral political organizations in a series reaching back to the primitive tribal community.’ And so with all the aspects of society. Whether we are studying a creed, a code of laws, a dialect, a system of philosophy, a congeries of myths, or a set of manners and customs, we can arrive at the rational solution of our problem only through a historical inquiry. Hence the doctrine of genesis, indispensable as it is in the _ other two organic sciences, becomes, if one may say so, even more indispensable in sociology. Here the whole science rests upon sociogeny, and until we have reached a scientific conception of progress we cannot stir a step. Thus, in addition to the unparalleled complexity of its phenomena, and to its general dependence both for doctrine und for method upon the simpler sciences, we perceive still another reason why the science of sociology has been the last to be constituted. Resting as it does upon the law of pro- gress, it has had to wait not only until the preceding sciences 1 See’ Mr. Freeman’s book, Comparative Politics,--the work of a great roaraeetl dag inherits the gift of Midas, and makes gold of every subject that @ touches. 1236 COSMIC PHILOSOPHY, [er. 11. were founded, but until they were sufficiently advanced to supply it with the general formula of organic development, from which alone the law of social progress could be deduced. It was not enough that Bichat had laid the foundations for a general theory of nutrition, reproduction and innervation, or that James Mill had established the fundamental laws of association ; though this was indeed much. The new science had to wait until Von Baer had traced the order in which organisms develope, until Mr. Darwin had shown how through heredity and natural selection organisms become adapted to their environments, and until Mr. Spencer had shown how associated ideas and emotions are slowly generated and modi- fied in conformity to surrounding circumstances. All this, of course, could not be foreseen by Comte. But he nevertheless clearly saw—and it does honour to his philo- sophic acumen—that a comprehensive theory of social changes can be obtained only by studying them in the order of their historical dependence. He saw that the laws of sociology are at bottom the laws of history. And especially, from the practical point of view, he saw that no general theory fit to serve as a basis for the amelioration of society could be de- duced from mere abstract reasonings about human nature, or obtained inductively from the mere observation of contem- porary social phenomena. All theories formed in this way, without reference to the order of historic progression, are in danger of being stated too absolutely, and are wont to give birth only to utopian projects. Comte was never weary of pointing out the errors of those political economists who ieduce general laws of accumulation and distribution from the industrial phenomena presented by a single country at a particular epoch ; or of those moralists who base their theories upon that absurdest of aphorisms, that “human nature is always and everywhere the same”; or of those legislators who, in ignorance of the fact that humanity is travelling in a definite and partially ascertainable direction, fondly hope to De et ee pa. x1x.] ILLUSTRATIONS AND CRITICISMS. 237 turn it hither and thither by shrewdly-concocted acts of par- liament. Nor, in maintaining this last position, did he ever fall into the opposite error—characteristic of superficial writers like Macaulay and Buckle—that individual genius and exertion is of little or no account in modifying the course of history. He did not forget that history is made by indi- vidual men, as much as a coral reef is made by individual polyps. Each contributes his infinitesimal share of effort: nor is the share of effort always so trifling. Considering the course of history merely as the resultant of the play of moral forces, is there not in a Julius Cesar or a Themistokles as large a manifestation of the forces which go to make history as in thousands of common men? Nevertheless the fact remains that civilization runs in a definite path, that the sum-total of ideas and feelings dominant in the next genera- tion will be the offspring of the sum-total of ideas and feel- ings dominant in this, and that only by understanding the general course of the movement of humanity can we hope to make our volitions count for much as an item in the resulting ageregate of effects. Holding such views as these, Comte saw that the first aim of the sociological inquirer must be to ascertain the law of progress. And accordingly he set himself to work to perform this task, with the only instrument then at his command,— that of historical induction. I have already remarked upon his wonderful skill in the use of that instrument of research. ~I doubt if anyone has ever lived who had a keener sense of the significance of historic events, so far as such significance could be perceived without the aid of conceptions furnished by the sciences of organic development. The fifth volume of the “ Philosophie Positive” is certainly a marvellous tableau of the progress of society. I know of no concrete presenta- tion of universal history which can be compared with it. The general excellence of the conception is matched by the excellence of the execution even to the smallest details. And 238 COSMIC PHILOSOPHY. (Pr. 1, amid the host of pregnant suggestions concerning Greek and Roman, and especially concerning medieval, history, the great fact that there has been and is a determinate order of sequence in human affairs is placed quite beyond cavil on the highest plane of inductive demonstration. To achieve so much as this was to show that a science of sociology is possible, and to prepare the way very thoroughly for the creation of such a science. But Comte professed to have done more than this. He regarded himself as the founder of sociology, and is so regarded by his disciples. It is part of our business to determine, if we can, whether the claim is a valid one; and in order to do this, we must examine the theorems which Comte propounded as the fundamental laws of progress. : These theorems are two in number,—the first relating to the intellectual, the second to what we may call the material, development of mankind, The first is an old acquaintance, being nothing else than the generalization that all human conceptions must pass through three stages—the theological, the metaphysical, and the positive. We have already (Part I. chapter vii.) examined this theory upon its own merits. Tried by a psychological analysis, we have found it to be only partially true. We saw it to be correct in so far as it asserts that the prevailing conception of the world becomes less and less anthropomorphic from age to age; but incorrect _in so far that it asserts that in this deanthropomorphizing process there are three radically distinguishable stages, and also, in so far as it asserts that the process must end in Posi- tivism, We saw that, although without doubt men began by seeing volition everywhere and must end by seeing an in- scrutable Power everywhere, nevertheless the mental process has throughout been one and the same, and any appearance of definite stages can be only superficial. Nevertheless, between the primeval savage who prays to his fetish and the modern philosopher who recognizes that he must shape his eS ST a ed > i ew. x1x.] ILLUSTRATIONS AND CRITICISMS. 239 conduct according to invariable laws or pay the penalty in some form of inevitable suffering, the difference in mental attitude is so vast that we may well have a distinction in terms to correspond to it. It is for this reason that I have frequently contrasted Anthropomorphism and Cosmism as the initial and final terms of a continuous progression. This, however, is not the Comtean doctrine. Again, metaphysics, as Comte understands it, being merely imperfect scientific inquiry conducted by the aid of the subjective method be- queathed by anthropomorphism, cannot be regarded as the peculiar possession of any particular stage. But while Comte’s theorem, in spite of these radical defects, contains a germ of truth and has been found to be eminently useful as a formula for intellectual development, I cannot but be surprised that Comte should have regarded it as the fundamental law of social progress, and still more that such able writers as Mr. Mill and Mr. Lewes should at the present day be found countenancing such an opinion. Does this “law” explain how it was that Greek civilization pre- maturely failed ? Does it throw any light upon the causal connection between Roman universal dominion and the Christian sentiment of the brotherhood of men? Does it recognize the distinction between the growth of a community in size and its growth in structure, or hint to us that the differences between Chinese and European civilization may be summed up in the statement that China is only a stupen- dous tribal community, while Romanized Europe is virtually a federation of exceedingly heterogeneous national aggre- gates? And while, as we shall presently see, it uncon- sciously recognizes that intellectual development is a con- tinous process of adaptation, does it say anything about that slow process of emotional change by which the more har- monious co-operation of societies and the more perfect freedom of individuals are alike rendered possible? Indeed it says nothing about any of these things; and I must think 240 COSMIC PHILOSOPHY, : ee that these are very extensive lacune in a theorem which professes to be the fundamental law of social progress. But this formula, as it stands, is not the whole of Comte’s fundamental law of history. With the advance from theolo- gical, through metaphysical, to positive conceptions of the world, Comte couples an advance from military to industrial life, through an ill-defined intermediate stage—inserted, doubtless, to complete the threefold parallelismm—which he calls the “legal” stage. Thoroughly to explain what he means by this “legal” stage of society, would require more detail than I can here well indulge in. We must be content with observing that he means to designate that epoch, which indeed we have not yet left behind us, in which parlia- mentary legislation is thought competent to renovate society artificially—in which it is supposed that legislatures can make men rich by giving them paper-money, intellectual by pa‘ronizing literature, temperate by closing dram-shops. As this phase of opinion was very conspicuous in the eighteenth century, coupled with metaphysical systems of political ethics deduced from revolutionary theories of the “inherent rights of man,” Comte links this whole set of doctrines together, and makes a so-called metaphysico-legal stage in social progress. But I cannot think this a happy generali- zation. This “legal” stage is, at the best, a phase of intel- zectual development, and to introduce it into the midst of a purely social progress from military to industrial life, seems too much like committing the logical fallacy known as cross- division. Omitting this stage, then, and reducing Comte’s double formula to its lowest terms,—the only ones, I think, upon which he himself would invariably have insisted,—we have the following, as the Comtean law of progress :— The progress of society is a gradual change from anthro- pomorphic to positive conceptions of the world, and from military to industrial modes of life; and the latter kind af change 1s determined by the former. cH. x1x.] ILLUSTRATIONS AND ORITICISMS. 241 Such is the form of statement most favourable for Comte, and at the same time I believe it to be the one which best represents his permanent opinion, We shall presently see that the generalization of the change from military to in- dustrial modes of life is one of great value, and it is to the thorough elaboration of it that much of the merit of Comte’s social philosophy is due. But I must first call attention to the fatal defect in the above formula, the defect which destroys its claim to be regarded as the law of progress. That fatal defect is its total omission of moral feeling as a factor in social evolution. Though he is far from committing Mr. Buckle’s absurdity of denying that there has been any improvement in moral feeling, Comte nevertheless falls into substantially the same error with Mr. Buckle, in attempting to explain all social progress as due simply to a progressive alteration of opinion. The error is one which seems to be shared by two other eminent writers——Mr. Mill and Mr. Lewes. Here are the statements of the four: Mr. Mill says, “We are justified in concluding that the order of human progression in all respects will mainly depend on the order of progression in the intellectual convictions of mankind.” ! Mr. Lewes says, somewhat more vaguely, “The evolutions of Humanity correspond with the evolutions of Thought.” ? Mr. Buckle says, “ The progress of mankind depends on the success wiih which the laws of phenomena are investigated, and on the extent to which a knowledge of those laws is diffused.”* Comte says, “It is not to the readers of this work that I think it necessary to prove that ideas govern the world, and that the social mechanism reposes ultimately upon opinions.” 4 | Now it is not so much because of what these propositions assert as because of what they omit, that they must be pro- 1 System of Logic, 4th edit., vol. ii. p. 517. 2 Philosophy of the Sciences, p. 23. 8 History of Civilization, vol. ii. p. 1. 4 Philosophie Positive, tom. i. p. 48. VOL. II. R 242 COSMIC PHILOSOPHY. [rr. 1, nounced unsatisfactory and misleading. It is beyond ques- tion that the progress of mankind does depend upon the progressive conformity of the order of their conceptions to the order of phenomena; but, after the inquiry contained in the preceding chapter, I believe no further proof is necessary to convince us that the progress of mankind also depends upon the progressive conformity of their desires to the requirements arising from their aggregation in communities. If civilization is a process of intellectual adaptation, it is also a process of moral adaptation; and the latter I believe to be the more fundamental of the two. The case is well stated by Mr. Spencer, in the following passage: “Ideas do not govern the world; the world is governed by feelings, to which ideas serve only as guides. The social mechanism does not rest finally upon opinions; but almost wholly upon character..... All social phenomena are produced by the totality of human emotions and beliefs: of which the emotions are mainly predetermined, while the beliefs are: mainly post-determined. Men’s desires are chiefly inherited ; but their beliefs are chiefly acquired, and depend on surrounding conditions; and the most important surround- ing conditions depend on the social state which the prevalent desires have produced. The social state at any time existing is the resultant of all the ambitions, self-interests, fears, reverences, indignations, sympathies, etc., of ancestral citizens and existing citizens. The ideas current in this social state must on the average be congruous with the feelings of citizens ; and therefore, on the average, with the social state these feelings have produced. Ideas wholly foreign to this social state cannot be evolved, and, if introduced from without, cannot get accepted—or, if accepted, die out when the temporary phase of feeling which caused their acceptance ends.” This statement, I may observe in passing, is well iliustrated by the abortive attempts of missionaries to civilize the lower races of mankind by converting them to Christi- tH. xix.) ILLUSTRATIONS AND CRITICISMS. 243 anity. Though they sometimes succeed in procuring temporary verbal acceptance for Christian ideas, they almost always fail in effecting a genesis of Christian feeling, and such civiliza- tion as they are able to produce is apt to be both supcrficial and transient, This is simply because civilization is not a mere process of external acquirement, but is a process of slow adaptation or breeding, which requires many generations to effect a permanent, modification of character. The Fiji, whose language contains no words expressive of the higher emotions or the more exalted principles of action, cannot be made into a Christian. You may cover him with a very little of the external varnish of civilization; you may astonish him into accepting a few formulas, to him quite unintelligible, concerning the relations of man to his Creator; but, after all, he remains a savage still, in feelings and in habits of thought, bloodthirsty, treacherous and superstitious, with a keen appetite for human flesh. Or suppose you could resuscitate a medizval baron—one of those innumerable freebooters who lived entrenched in the romantic castles of the Rhine and levied blackmail on every luckless wayfarer—suppose you could resuscitate such a man, and were to endeavour to expound to him in the simplest language a few of the most self-evident modern axioms concerning political rights and the interdependence of human interests: would he under- stand you? By nomeans. So vast would be the difference in mental habit, that in all probability he could not even argue with you. “ Hence ”—to continue with Mr. Spencer— ‘though advanced ideas when once established act upon society and aid its further advance; yet the establishment of such ideas depends on the fitness of the society for receiving them. Practically, the popular character and the secial state determine what ideas shall be current; instead of the current ideas determining the social state and the character. The modification of men’s moral natures, caused by the r 2 244 COSMIC PHILOSOPHY, [er. 11. continuous discipline of social life, is therefore the chief proximate cause of social progress.” It is worthy of note that Comte, in his later period, comes partly around to this very point of view. At the becinning of the “ Politique Positive,” we find him announcing that the increasing tendency in the altruistic impulses to prevail over the egovistic impulses is the best measure by which to judge of the progress of society. Yet the unsteadiness with which he grasped this principle is revealed by the somewhat misty statement, a few pages further on, that “the co-ordination of human nature as a whole depends ultimately upon the coordination of intellectual conceptions.” A similar fluctuation in opinion may be noticed in Mr. Buckle; and it was indeed hardly possible for the function of moral feeling as a factor of progress to be thoroughly understood by writers unacquainted with the laws of adaptation upon which the scientific interpretation of that function is based. But whatever Comte’s latest opinions may have been, since he never formulated any law to include the action of moral feeling as a factor of progress, his claims to be regarded as the founder of sociology must rest entirely upon his theory of progress as announced and ny illustrated in the “ Philosophie Positive.” That theory, as we now see, is much too incomplete to serve as the foundation for a scientific study of history. Civilization cannot be summed up in the correct formula that men’s occupations begin by being military and end by being industrial, or in the incorrect formula that men’s con- ceptions of the world begin by being anthropomorphic and end by being positive; nor is it true that the former change is determined by the latter. We need to add the formula that men’s feelings begin by being almost purely egoistic and " must end by being altruistic to a considerably greater extent than will suffice to prevent individual interests from clashing. 4 Politique Positive, tom. i. p. 16, cH. x1x.] ILLUSTRATIONS AND CRITICISMS, 245 And even with all three formulas before us, we need some- thing more before we can say that we have obtained the Law of Progress. These formulas are historical generalizations of great value; but as thus announced, they are too isolated with respect to each other. The progress of society is not moral progress, or intellectual progress, or material progress ; but it is the combination of all the three, Our three for- mulas, therefore, must be integrated in a single formula. And this is done, and satisfactorily done, when it is shown that they are all involved in that law of adaptation or adjustment which underlies sociology, as well as psychology and biology. That the progress from egoism to altruism is involved in that fundamental law, was proved in the preceding chapter, and has been illustrated throughout the whole of this dis- cussion. But the law of adaptation equally involves the progress from Anthropomorphism, not to Positivism, but to Cosmism, as a necessary corollary. For what does that progress depend upon? What is the underlying process of which it is the necessary symptom and result? Why is it that men begin by investing the unknown causes of pheno- mena with quasi-human attributes and end by recognizing a single Cause which is inscrutable? In treating of deanthro- pomorphization (Part I. chap. vii.) we examined this point. We perceived the primitive anthropomorphism to be a corol- lary from the relativity of all knowledge. We saw that, to interpret phenomena at all, men must interpret them in terms of their own consciousness, We saw that before the dawn of science, when events seemed isolated and capri- cious, the phenomenon itself was by a natural inference-— which only the progress of science has taught us to correct— endowed with a quasi-human personality. We traced the manner in which, as phenomena become generalized in wider und wider groups, the causes of phenomena become con- veived as more and more abstract, and become stripped by slow degie:s of their anthropomorphic vestments. Until 246 COSMIC PHILOSOPHY. (pr. 1 finally, when generalization has proceeded to such an extent as to give us a single grand science of Cosmology, dealing with the Universe as an integral whole, there comes to be recognized a single Cause of phenomena, which, as being infinite, cannot be in any anthropomorphic sense personal, and which, as being absolute, must be inscrutable. Thus we see that Comte’s formula is not fundamental, even as a formula for intellectual development. The pro- cess of deanthropomorphization is not the fundamental fact. The continuous organization of knowledge and generaliza- tion of phenomena is the fundamental fact, of which the con- tinuous deanthropomorphization is the necessary symptom and result. Now in Part I. chap. ii, we traced the out- lines of this continuous organization of knowledge; and we found that the advance from incomplete to complete know- ledge consists in the continuous establishment of groups of notions which are ever more coherent within themselves, while they are ever more clearly demarcated from one another. Now what is all this but a continuous process of differentiation and integration? When we say that from first to last, from the simplest cognitions of infancy to the widest generalizations of science, we cognize phenomena invariably through difference and likeness, we mean that we are continually differentiating notions answering to unlike phenomena and continually integrating notions answering to like phenomena. Or, to express the same thing in other words, we are continually establishing relations of likeness and unlikeness among our conceptions, that in some way or other definitely correspond to relations of lfkeness and un- likeness among phenomena. Thus our intellectual progress is at bottom a process of adaptation. And, when treating of the Test of Truth (Part I. chap. iii), it was shown that Truth, the goal of intellectual progress, is nothing else than the complete adaptation of the order of conceptions to the order of phenomena,—the establishment of inner relations en. xix.) IZLUSTRATIONS AND CRITICISMS. 247 that are in equilibrium with outer relations. Thus we obtain a ~eritable law of intellectual progress; whereas to say that men’s conceptions pass from Anthropomorphism to Positivism is merely to enunciate an empirical generalization, which, besides being empirical, is also radically imperfect. The gradual change from a military to an industrial life must also seek its rational explanation in the law of progress as above formulated. The diminution of warfare and the concomitant increase of devotion to industrial pursuits are entailed by the growth of communities in size and structure. Among the primitive tribal societies there is no industrial life save that implied in hunting and fishing, and at a some- what. later date in the rearing of domestic animals. Settled agricultural pursuits require a greater power of continuous application and a more developed ability to subordinate present enjoyment to the anticipation of future needs than is to be found in the primitive savage. It is only the mental habit produced by long-continued social discipline which enables us to work to-day that we may enjoy the fruits of our labour at a distant period. The primeval tribe wanders from spot to spot, seeking ever a better hunting-ground or richer pasturage, leading a predatory life which differs in little save in its family organization from that led by the lower animals. In this stage of society constant warfare is inevitable, since each tribe must fight or be erushed out of existence by neighbouring tribes. Over a large part of the earth’s surface, such has been the monotonous career of savage man from the earliest times until the present day. Such appears to have Leen, in its main features, the ancient history of our own country before its conquest by Europeans, as it is admirably delineated in the writings of that acute observer Mr. Parkman. The exigencies of warfare, however, of themselves facili- tate that integration of tribal communities which we have seen to be the indispensable condition of progress, A con+ 248 COSMIC PHILOSOPHY, (Pr. um. siderable step toward civilization is taken when tribes begin to aggrecate for mutual defence over a wide tract of country. When America was discovered, an aggregation of this sort had apparently begun to be formed among the Iroqaois; and such was the highest organization reached by the ancient Turanian tribes of Central Asia. A far more important step is taken when warfare ceases to be purely destructive and becomes acquisitive; or, in other words, when the victors, instead of massacreing the vanquished, begin to make slaves of them. By this step agricultural industry is fairly brought into existence, and the tribal confederacy becomes fixed in location and enabled to increase indefinitely in size at the expense of the less highly organized communities in the neighbourhood. Under these conditions the tribal con- federacy may grow until it takes on the semblance of an “agoregate of the third order,’ as in China,! or in ancient Egypt, Assyria, Media, Lydia, and Persia. I am expressing something more than an analogy: -I am describing a real homology as far as concerns the process of development— when I say that these communities simulated modern Euro- pean nations much in the same way that a tree-fern of the carboniferous period simulated the exogenous trees of the present time. The vast growth and the considerable civi- lization obtained by such communities were rendered possible only through the institution of industrial slavery in place of the primeval indiscriminate slaughter of captives. Only through enforced labour did the continuous culture of the soil and the consequent stability of society become possible ; 1 “In every respect the Chinese constitution of society may be regarded as a gigantic amplification of the constitution of the family. The family is no doubt the constituent element of which all societies are composed ; just as, in the body, all tissues, nervous or muscular, are generated from the primitive cellular tissue ; but whereas in other societies we find differentiation into classes and institutions which have no direct analogue in the family, in China we find far less of this, far more of adherence to the primitive social tissue, to the patriarchal type. On this type the village and the empire are alike moulded.” Bridges, in Lssays on International Polity, p. 401. on. x1x.]} ILLUSTRATIONS AND CRITICISMS, 249 a point which Comte clearly saw, and has brilliantly illustrated. Thus we see how the exigencies of self-protection entailed by the primitive state of universal warfare furnished of themselves the conditions for the rise of industry. We need not trace in detail the slow growth of the industrial spirit at the expense of the military spirit in the ancient civic communities, in the ancient and medieval Empire, and in modern times, That has been done, with a masterly hand, by Comte. We may only note briefly how industry—the offspring of slavery, itself the offspring of warfare—has all along, by aiding the differentiation and integration of society, been draining the vitality out of its primeval parent. Let us note, then, that the kind of differentiation, known as “division of labour,” by rendering the various portions of the community more and more dependent on each otlier, renders a state of warfare ever less easy to sustain, and therefore continually, though slowly, diminishes the frequency and shortens the continuance of wars. The statement that in early times a community is, on the whole, better able to endure protracted warfare than in later times, may be illus- trated by a comparison between the Punic Wars of Rome and the War of Secession in our own country. The horrible destruction of life and property occasioned by the first and second Punic wars is minutely described in Mommsen’s “Kouun History.” The first of these desperate struggles lasted twenty-three years, during the five severest of which the vensus of Roman patricians was diminished by one-sixth of the whole number,—a fact terrible to contemplate when its full significance is realized. After twenty-three years of com- parative quiet began the still more deadly struggie against Hannibal, which lasted seventeen years. During this war, the total loss of life in all the communities engaged—‘talian, Spanish, Sicilian, and African—cannot be estimated at less than 600,000 persons actually slain; a loss which I believe 250 COSMIC PHILOSOPHY, [pr. 11. somewhat exceeds that of the Northern and Southern States in the American war. But to make a fair comparison, we must include the circumstance that the population of these ancient communities was not more than one-sixth as great as the population of the United States; and that in ancier times the normal rate of increase of population was very much slower than in such a community as ours. The second Punic war was, therefore, relatively as murderous as our civil war would have been had it continued until between © three and four million lives were destroyed. And if we would appreciate the direct damage to industry which it entailed, we have a sufficient datum in the fact that during those seventeen years more than four hundred flourishing towns and villages in Italy alone were blotted out of existence.! Now opinions may differ as to the possibility of our carrying on for seventeen years a war which should drain our resources as the Hannibalic war drained the resources of Italy. Probably no country could so well sustain such a trial as the United States, owing to the favourableness of our social conditions for exceedingly rapid growth in wealth and population. Nevertheless, even omitting foreign interference from the account, I do not believe the thing would be possible. I believe it perfectly safe to assert that a war like the one we have lately passed through would, if prolonged to seven- teen years, entail social disintegration throughout the com- munity. Yet the absolute military power of the United States is incomparably greater than that of ancient Rome: wherein, then, lies the difference ? The explanation will be found, and the particular conclu- sion reinforced, when we consider the enormous increase of heterogeneity and interdependence in the modern as con- trasted with the ancient community. In ancient Italy there was but little division of labour: it required but a few simple 4 Mommsen, Réimische Geschichte, tom. i, p. 671 5 see also p. 536. cn. x1x.] ILLUSTRATIONS AND CRITICISMS. 251 occupations to supply the wants of the whole community. In the United States considered as a whole, the division ot labour is perhaps not quite so extreme as in western Europe, owing to the sparseness of population and the purely agricul- tural activity of large sections of the country: still, the inlustrial differentiation is very great, and to supply the wants of each portion of the community a vast number of mutually dependent and highly complicated occupations is indispensably necessary. Obviously the heterogeneous com- munity cannot so well bear the abstraction of units from its mutually dependent parts, as the homogeneous community could bear the abstraction of units from its relatively in- dependent and self-sufficing parts. The difference is much the same as the difference between cutting off portions of ‘a worm and cutting off portions of a vertebrate animal. You may take one of the lower worms and slice away at it for some time without destroying it, but in the case of the vertebrate a comparatively small loss of parts entails destruction. In society the principle is the same. The Romans could lose army after army, while the few who remained at home could carry on all the agricultural and commercial operations necessary to the maintenance of the community. There were no great organized industries, manufacturing or commercial, so linked together that the destruction of any one might cause general financial disaster. But in any large modern community industry has yecome so heterogeneous that it is difficult for one part to take on the functions of another part, and so completely integrated that a sudden and considerable withdrawal of men from the ordinary pursuits of life can hardly take place without causing widespread suffering, And the contrast is made still greater by the industrial federation of modern communities as compared with the industrial isolation of ancient states. Though the time has perhaps never been, since Mediterranean civilization began, when a war could 252 COSMIC PHILOSOPHY, [PT. 11 continue very long in one community without tending to set up disturbance in some other, yet this interaction of different states was far less conspicuous in ancient than it is in modern times. The Hannibalic war might go on for seven- teen years, and Athens or Alexandria not be much the worse off for it. But before the war of secession had continued twelve months, the consequent suffering in Lancashire was manifesting itself in riots, and England for a time seemed willing at all hazards to interfere and check the contest. This single example—out of hundreds that might be taken —must suffice to illustrate the way in which the ever- increasing interdependence of human interests, itself both the cause and the effect of industrial progress, is ever making - warfare less and less endurable. To this it must be added that both moral and intellectual factors contribute to bring about the general result. As human interests in various parts of the world become more and more inextricably wrought together, and as communities which lie apart from each other come ever into closer contact, the ancient an- tagonisms of sentiment between them slowly disappear, and international friendship grows at the expense of the old hostility or distrust. Thus the moral adaptation due to long- continued social discipline diminishes the warlike feelings and strengthens the feelings which maintain an industrial régime; while on the other hand, intellectual adaptation, ever adding new complication to industry, arrays the opinion of society more and more decidedly against war, as against un intolerable source of disturbance. Besides which, the very heterogeneity of the military art, the increasing cecm- plication both of the implements and of the methods of war- fare, due to scientific and industrial progress, renders war ever more costly, and makes the community less willing to engage in it. And these cooperating processes must go on until] —probably at no very distant period—warfare shall have become extinct in all the civilized portions of the globe, cu. x1x.) ILLUSTRATIONS AND CRITICISMS. 253 In so far as the present chapter has dealt with the claims of Comte to be regarded as the founder of Sociology, I believe it is sufficiently proved that these claims cannot be sustained, though in many ways he did more than anyone else to pre- pare the way forsuch an achievement, Ifa man can ever be properly said to create or found a science, it is only when he discovers some fundamental principle which underlies the phenomena with which the science has to deal, and which thus serves to organize into a coherent ratiocinative body of knowledge that which has hitherto been an incoherent em- pirical body of knowledge. It was in this way that Newton may be said to have created a science of celestial dynamics, and that Bichat is sometimes, and more loosely, said to have been the founder of modern biology. In no such sense can Comte be said to have created sociology. Standing on the vantage-ground of contemporary science, which enables us to discern in outline the law of progress, we can see not only that Comte was far from detecting that law, but that, with the limited appliances at his command, he could not have been expected to discover it. Nevertheless his contributions to sociology were exceedingly brilliant and valuable, and he did perhaps all that the greatest thinker could have done forty years ago. He arrived at a double generalization of the phenomena of intellectual and material progress, as wide as could then be reached by unaided historical induction; and he verified this double generaliza- tion by an elaborate survey of ancient and modern history, which, even had he written nothing else, would alone suffice to make his name immortal. It entitles him, I think, to be ranked first among those sociologists who have proceeded solely on the historical method,—on a somewhat higher plane, perhaps, than Vico or Montesquieu, Turgot or Con- dorcet. That generalization, in both its branches, and in so far as it is correct, we have here seen to be a corollary from the fundamental law of social evolution obtained in the pre- 254 COSMIC PHILOSOPHY. (PT. 11, ceding chapter. We have seen that the continuous adapta- tion, both moral and intellectual, of the community to its environment, involves, as necessary concomitants, both the progressive deanthropomorphization of men’s conceptions of Cause, and the gradual change from military to industrial habits of life. And the harmony between the results thus obtained by pursuing two wholly independent lines of inquiry, adds fresh support both to the fundamental law and to its historic ccrollaries, In the very act of proving that Comte did not achieve the whole, we do but place what he did achive upon a deeper and firmer basis, CHAPTER XX. CONDITIONS OF PROGRESS At the beginning of the chapter on the Evolution of Society we remarked upon the error of those metaphysical writers who have gone so far as to ascribe progressiveness to an occult tendency inherent in human nature. It need not take a very long survey of human societies, past and present, to assure us that beyond a certain point stagnation has been the rule and progress the exception. Over a large part of the earth’s surface the slow progress painfully achieved during thousands of prehistoric ages has stopped short with the savage state,as exemplified by those African, Polynesian, and American tribes which can neither work out a civilization for themselves, nor appropriate the civilization of higher races with whom they are brought into contact. Half the human race, having surmounted savagery, have been arrested in an immobile type of civilization, as in China, in ancient Eeypt, and in the East generally. It is only in the Aryan and some of the Seinitic races, together with the Hungarians and other Finnic tribes subjected to Aryan influences, that we can find evidences of a persistent tendency to progress. And that there is no inherent race-tendency at work in this is shown by the fact that some of the Aryaus, as the Hindus and Persians, are among the most unprogressive of men. It 256 COSMIC PHILOSOPHY. [er. 1. becomes apparent, therefore, that the progress of the European Aryans, and of such other races as have from time to time arisen from an immobile condition, can have been due only to a concurrence of favourable circumstances. In order to complete our outline-sketch of the Evolution of Society, we must consider some of these circumstances, and thus, so far as possible, redeem the promise which was implied at the beginning of the discussion. By pointing out some of the conditions essential to progress in civilization, we must en- deavour to throw a glimmer of light upon the fact that so small a portion of the human rece has attained to per- manent progressiveness. A faint glimmer of enlightenment is indeed the most we can hope for, and even this will perhaps be thought to have been obtained by a mere re- statement of the problem in other words. Nevertheless, in other departments of study as well as in algebra, much good is often done by reducing a problem from one form of ex- pression to another. For if such a reduction ends in classi- fying the problem, the first and most important step is taken toward a solution. Let us deal in this way with the pro- blem before us, which is one of the most complex and difficult that the history of the world presents. It will be obvious to everyone that there is a close kin- ship between this question in sociology and the biological question why certain species remain unchanged through countless ages. The latter fact has been urged as an obstacle in the way of the development theory, and has been felt to be such by Dr. Bastian, who has endeavoured to dispose of it by an extraordinary application of his favourite theories of archebiosis and heterogenesis But indeed those who urge this fact as an obstacle, and those who seek to explain it away, show that they have not thoroughly comprehended the Doctrine of Evolution. For example, it is not implied in the general law of evolution, as above expounded in 1 Bastian, Beginnings of Life, vol. ii. pp. 584—640. cH. Xx.] CONDITIONS OF PROGRESS. 257 Chapter IV., that wherever the integration of. matter and concomitant dissipation of motion are going on, there must always ensue a change from indefinite uniformity to definite multiformity of structure. As has already been shown, such - a change can be expected to take place only when a number of specified circumstances concur in forwarding it. So it is one of the peculiar merits of Mr. Darwin’s theory of natural selection, that it does not allege an unceasing or ubiquitous alteration of animal and vegetal forms, but includes, in a general way, all cases of persistence of type, as well as all eases of proyress or retrogression. One and the same general theory accounts for the fact that, while some species thrive in the struggle for life and acquire new capacities, others dwindle in numbers or deteriorate in structure, while others again maintain themselves unchanged throughout immense periods. Throughout all these cases, the general truth is easily discerned that the total result will depend upon a very complex combination of circumstances: the difficulty is in applying the general truth to the special cases that arise. Probably no naturalist could point out all the specific circum- stances which have caused any one race of animals to prevail over another in the struggle for life. Such a task would probably demand a more vast and minute knowledge of the details of the organic world than it is as yet possible for the most unremitting industry, inspired by the highest genius, to acquire. Yet no one doubts the general principle that it is natural selection which determines, not only which races shall prevail, but also which races shall vary and which shall remain unmodified. Soin dealing with human societies, in the primitive era with which the present discussion is chiefly concerned, the historic data are insufficient to enable us to ascertain the precise circumstances to which the prevalenze and the improvahility of certain races are to be attributed. Nevertheless we can here, too, point out sundry general VOL, II. 8 258 COSMIC PHILOSOPAY. [vr. 1 principles in accordance with which natural selection has determined the course of events. In considering the action of natural selection upon the human race, we must first note how that action is, in some respects, materially modified by social conditions. Among inferior animals, even those which are gregarious, as the ruminants and sundry smaller carnivora, the preservation of any individual requires his almost complete adaptation to surrounding circumstances. There is so little division of labour, and consequently so little mutual assistance, that all must be capable who would survive. With the earliest manifestations of true sociality this state of things must be somewhat altered. Even in the rudest actual or ima- ginable society there is some division of labour, and some mutual assistance. Those who are less swift for hunting or less strong for fighting may at least perform services for the hunters and warriors, and in return will be more or less efficiently fed and protected; so that those who fall below the average capability of the race are no longer sure to be prematurely cut off, and thus the agency of natural selection in keeping up a nearly uniform standard of fit- ness is to some extent checked. In the highly complex societies which we call civilized, division of labour and co- operation have done much to obscure the effects of this agency. From the cooperation which goes on to a greater or less extent in all societies, and from the enormous hetero- genelty of man’s psychical organization, it follows that there are innumerable circumstances which may enable individual men to survive, in spite of their falling considerably short of the normal standard of the community and the age to which thev belong. This fact, as will hereafter appear, renders it possible for man to have an ideal standard of excellence or successfulness in life, and is closely associated with the genesis of the ethical feelings of approval and disapproval. But while natural selection among individuals grows some. cH, Xx.] CONDITIONS OF PROGRESS. 259 what less rigorous, its effects upon rival or antagonist societies are in nowise diminished in their beneficent severity. The attributes which tend to make a society strong and durable with reference to surrounding societies, are the attributes which natural selection will chiefly preserve. As Mr. Wal- lace has pointed out: “Capacity for acting in concert for protection, and for the acquisition of food and shelter; sym- pathy, which leads all in turn to assist each other; the sense of right, which checks depredations upon our fellows ; . .. self-restraint in present appetites; and that intelligent foresight which prepares for the future, are all qualities that from their earliest appearance must have been for the benefit of each community, and would therefore have become the subjects of natural selection. Tribes in which such mental and moral qualities were predominant, would have an ad- vantage in the struggle for existence over other tribes in which they were less developed, and would live and main- tain their numbers, while the others would decrease and finally succumb,” ? The most conspicuous result of this unceasing operation of natural selection upon rival communities, has been the continuous increase of the aggregate military strength of the human race, and the more and more complete segre- gation of this military strength into those portions of the race which are most civilized. As Mr. Bagehot has ably shown,” however broken or discontinuous the provressive career of the European family of nations may seem to have been in other respects, there can hardly be a doubt that the increase of their aggregate military force has been un- interrupted. There can hardly be a doubt that the total fighting power of the Mediterranean communities was greater 1 Wallace, Natural Selection, p. 812. 2 See his Physics and Politics, London, 1872,—a little book so excellent both in thought and in expression that one cannot but wish there were much more of it, & 2 260 COSMIC PHILOSOPHY. [pr. 11 under Trajan than in the time of Polybios; that the sum of Latx and Teutonic strength in the days of Charles Martel was greater than in the days of Marcus Aurelius; that the united Europe of Pope Gregory VII. could have vanquished the united Europe of Charles the Great, but would have been no match for the united Europe of Plilip, Elizabeth, and Henry; or that the existing generation of Aryans in Europe and America represents a greater quantity of mili- tary power than any previous generation. This result is partly due to the mere increase of the civilized communities in size and industrial complexity, and partly to the integra- tion, over wider and wider areas, of communities previously isolated. But while there have been periods of intermittence in the operation of these social and political circumstances, as during the Teutonic reconstruction of the Roman Empire, the increase in total fighting power appears to have gone on without intermittence, showing that it has been in great degree due to a cause unremitting in its operation. That cause has been natural selection. In the earlier and ruder times it has operated through the actual conquest of the weaker tribes, provinces, or cities, by the stronger. In later and more refined ages, the quieter but equally stringent com- petition of nation with nation, involving the possible conquest or relative humiliation of one by another, has caused a con- siderable proportion of the ever-accumulating intellectual and industrial acquirements of each nation to be expended (or, as Mr. Bagehot more happily says, “invested”) in an increase of military strength. From the cooperation of these circumstances the aggregate physical strength of civilized society has increased so enor- mously that in comparison with the military events of our time, the military events of antiquity seem like mere child’s play, if we look at physical dimensions alone, and not at world-historie significance. Ignoring the latter point of view, Mr. Robert Lowe has maintained that the battle of Marathon CH. Xx. ] CONDITIONS OF PROGRESS. 261 was an event of less importance than “a good colliery accident,” because forsooth only 192 lives were lost on the side of the Greeks!!_ To him, however, who has acquired the habit of looking at European history as one connected whole, it will not seem extravagant to say that contemporary English civilization is indebted to the victory of Marathon in a far higher degree than to the victories of Crecy or Agincourt, or even of Waterloo. The immense relative importance of some of these ancient military events of small dimensions, is due to the fact that military strength was not then concentrated in the most highly civilized communities, as it is in modern times. In antiquity there was a real danger that the nascent civilization of higher type might be extinguished by the long-established civilization of far lower type, or even by barbarism, through mere disparity of numbers. We do not know how often in prehistoric times some little gleam of civilization may have been put out by an overwhelming wave of barbarism, though by reason of the great military superiority which even a little civilization gives, such occurrences are likely to have been on the whole exceptional This great superiority is well exemplified in the ease with which the Greeks defeated ten times their own number of Asiatics at Marathon, and afterwards at Kynaxa. Nevertheless it cannot be questioned that the invasions ot B.c. 490 and 480 were fraught with serious danger to Grecian independence, and if Datis or Mardonios had happened to possess the military talent of Cyrus or of Timour, the danger would have been alarming indeed. Now if little Greece had thus been swallowed up by giant Persia, and the nascent political ana intellectual freedom extinguished in Athens as it was in the Ionic cities of Asia Minor, the entire future history of Macedonia, of Rome, and of Europe, would have been altered in a way that is not pleasant to contemplate. When we reflect upon the enormous place in human history 1 See Freeman, Comparative Politics, p. 498. 262 COSMIC PHILOSOPHY. [pT 11 which is filled by the products of Athenian intellectual activity during the two centuries succeeding the victory of Marathon; when we remember that the foundations of philosophy, of exact science, of esthetic art in all its branches, of historic and literary criticism, and of free political discussion, were then and there for ever securely laid; when we consider the widely ramifying influcnces, now obvious and now more subtle, of all this intense productivity upon Roman ethics and jurisprudence, upon the genesis of Christianity, upon the lesser Renaissance of the thirteenth century, and the greater Renaissance of the fifteenth; when we see how inseparably the life of Athens runs as a woof through the entire web of European life down to our own times ;—when we come to realize all this, we shall begin to realize how frightful was the danger from which we were rescued at Marathon and at Salamis, Probably at no subsequent time has European civilization been in a position of such imminent peril. In the life-and- death struggle between Rome and Carthage, the military superiority belonged so decidedly to the more highly-evolved community that even the unrivalled genius of Hannibal was powerless to turn the scale. One of the most conspicuous features in Roman history, from the conquest of Spain by - Scipio to the conquest of the Saxons by Charles the Great, was the continual taming of the brute force of barbarism, and the enlisting it on the side of civilization. In the earlier times there seems to have been real danger in the invasions of Brennus and of the Cimbri, and perhaps in that of Ariovistus. But with the conquest of Gaul and the more subtle process of Romanization which the Teutons underwent, the danger from these sources disappeared, until, when the great struggle with outer barbarism came in the fifth century, we see the Empire saved on a Gaulish field by the prowess of the West-Goth. The battle of Chalons seems 1 See Arnold, History of Rome, vol. iii. p. 68, cH. Xx.] CONDITIONS OF PROGRESS. 263 to me to liave been the last of the great fights in which the further continuance of European civilization was really imperilled. Though the victory of Attila could hardly have entailed the rebarbarizing of the whole Empire, it might well have caused such a temporary “solution of continuity” between ancient and modern history as the old historians supposed to have been wrought afew years later by the comparatively insignificant intrigues of Odoacer. Many hard-working years might have been needed to recover the ground thus lost. But in passing to the eighth century, I think we may well doubt the soundness of Gibbon’s suggestion that the victory of Abderahman at Tours might have led to the Moham- medanization of Europe; for while one great defeat forced the Arab to retire behind the Pyrenees, on the other hand the complete overthrow of the Frankish power would probably have required many battles as fierce as this one. This increased toughness of civilization is still more plainly seen five centuries later, when the overwhelming victory of the Mongols at Liegnitz produced no effect at all beyond a temporary scare. It was not that the invasion under Batu was intrinsically less forinidable than the invasion of Attila, but that the physical strength of civilized Europe had been growing throughout the long interval, so that the blow which might once have proved fatal was no longer dangerous, Since the fruitless sieges of Vienna by the Turks, the mere dread of barbaric or semi-.arbaric invasion has passed away for ever. Tribally-organized barbarism is henceforth out of the lists entirely, and even the civilization of lower type has ceased to compete, in a military way, with the civilization of higher type. Thus we see how natural selection, facilitating and co- operating with the integration of the more civilized communi- ties and their increase in size and complexity, has gradually removed one of the dangers to which the earlier civilizations were exposed, and has concentrated the power of making 264 COSMIC PHILOSOPHY. [prt war on a grand scale into the hands of those communities in which predatory activity is at the minimum and industrial activity at the maximum. We are thus again reminded of the curiously cooperating processes, partially illustrated in the preceding chapter, through which warfare or destructive competition, once ubiquitous, is becoming evanescent, and giving place to a competition that is industrial or productive in character. But what now more especially concerns us is to look back to the earlier stages of the struge¢le for life between communities, and to observe some of the circurn- stances which must have tended to make some communities prevail over others. The illustrations just cited show well enough the tendency of the higher type of civilization to prevail, in the long run, over the lower type. They are illustrations of the military advantages of civilization, And Mr. Bagehot has incidentally shown how thoroughly this fact disposes of the old-fashioned doctrine that modern savages are the degraded descendants of civilized ancestors. It was formerly assumed that, in- stead of mankind having arisen out of primeval savagery, modern savages have fallen from a primeval state of civili- zation, having lost the arts, the morality, and the intelligence which they once possessed; and of late years some such thesis as this has been overtly maintained by the Duke of Argyll. Such a falling off, upon any extensive scale, is in every way incompatible with the principle of natural selec- tion. Take, for example, the ability to anticipate future contingencies,—to abstain to-day that we may enjoy to- morrow. In the next chapter it will be shown that this is the most prominent symptom of the deepest of all the intei- lectual differences between civilization and savagery. Now, obviously, the ability to postpone present to future enjoy- ment is, in a mere economic or military aspect, such an im- portant acquisition to any race or group of men, that when enve acquired it could never be lost. The race possessing cH, xx.] CONDITIONS OF PROGRESS. 265 this capacity could by no possibility yield ground to the races lacking it, unless overwhelmed by sheer weight of vastly superior numbers,—a case which the hypothesis of a universal primitive civilization does not leave room for. Or take the ready belief in omens by which the life of the savage is so terribly hampered. Could a single tribe in old Australia have surmounted the necessity of searching for omens before undertaking any serious business, it would inevitably, says Mr. Bagehot, have subjugated all the other tribes on the continent. In like manner it is obvious that such implements as the bow and arrow and the iron swords or hatchets could never have given place to the boomerang and the knives and hatchets of stone or bronze; and the intellectual capacity implied in monotheism and the discovery of elementary geometry could never have been conquered out of existence by the intellectual capacity im- plied in fetishism and the inability to count above three or four. So, because the men who possess the attributes of civilization must necessarily prevail, in the long run, over the men who lack these attributes, it follows that there cannot have been, in prehistoric times, a general loss of the attributes, external and internal, of civilization. Now one of the attributes which will most surely give to any group of men an advantage in the competition with neighbouring groups, is the presence of a powerful bond of union between its members. Our entire survey of social evolution shows uncat one of the most distinctive character- istics of civilized men is their capacity for acting in concert with one another over wider and wider areas. The next chapter will enable us more fully to understand that the acquirement of this capacity is simply a further prolonging of the extension of correspondences in time and space which has been shown to be a leading characteristic of psychical progress throughout the organic world. The growth of this capacity, during historic times, has been a complex result of 266 COSMIC PHILOSOPHY. (ev. 11, the increase of progressive communities, in size, in hetero- geneity, and in reciprocity of intercourse. For this many-sided development has uot only entailed a relative weakening of the more anti-social impulses and a complicated interlacing of the interests of communities and individuals, but it has also entailed a general widening and diversifying of intellec- tual experiences, enabling men to realize the desirableness of those remoter ends which are indirectly secured by concerted action over wide areas. Thus in a high state of civilization a large amount of concerted action is ensured by the opera- tion of the ordinary incentives to individual activity, without the aid of extraordinary incentives especially embodied in eovernmental edicts, political, sacerdotal, or ceremonial. But in a primitive state of society it is quite otherwise. It is notorious that uncivilized men cannot be made to act in concert save under the stimulus of loyalty to a chief, or of reverence for some superstition, or of slavish obedience to time-honoured custom. Hence in early times those commu- nities are most likely to prevail, in which loyalty, reverence, and obedience are most strongly developed. From a military point of view there are hardly any other advantages which can outweigh these. Rigidity in family-relationships is one in- stance in which these advantages are manifested. A commu- nity in which the patria potestas is thoroughly established must inevitably subjugate those rival communities in which kin- ship is reckoned through females only. The common-sense of the old historians perceived and insisted upon the fact that much of the marvellous success of the Roman common- wealth was traceable to strictness of family-discipline. In like manner, as Mr. Bagehot has suggested, we may discern the true social function perfurmed by those dreadful religions of early times which so naturally awakened lvathing and horror in such thinkers as Lucretius: they enforced, with tremendous sanctions, such lines of conduct as were pre- scribed by the uecessities of the primitive community; they cH. Xx.] CONDITIONS OF PROGRESS, 267 rend-red it easier to ensure concerted action among men by compelling all to act in conformity to some unchangeable rule. In short, among numerous tribal groups of primitive men, those will prevail in the struggle for existence in which the lawless tendencies of individuals are most thoroughly subordinated by the yoke of tyrannical eustom,—the only yoke which uncivilized men can be made to wear. Such communities will grow at the expense of tribes that are less law-abiding. It matters comparatively little, as Mr. Bagehot says, whether the tyrant custom be intrinsically good or bad: the great thing, at first, is to subject men’s individualities to a system of common habits. Mr. Mill has complained, in his work on “ Liberty” and elsewhere, that one of the characteristics of modern civilization is the dis- appearance of strongly-marked individualities, such as we find in medieval and in ancient civilization. But surely he is quite mistaken in this,—and his mistake arises partly from neglect of the circumstance that in ancient and in feudal times the full manifestation of one powerful individuality was achieved only through the utter sinking of many weaker individualities, and partly from the fallacy of taking the unparalleled community of Athens as a type of ancient communities in general, Surely in no previous age has there been anything like so wide a scope for the manifestation of strongly-marked individuality of thought or character as in the present age. It would, indeed, be hardly too much to say that this is the first age in human history which has given us a realizing foretaste of the time when freedom of thought and freedom of action shall not only be acknowledged as a right but insisted upon as a duty for all men. But this is due to the fact that men’s natures have, through long ages of social discipline, be- come in some degree adapted to the social state. This relatively free recogniticn of idiosyncrasies in thought or 268 COSMIC PHILOSOPHY. [rr. m demeanour shows that modern society can count upon an organic or instinctive conformity to law on the part of individuals, upon which ancient society could not count, In early times, freedom from the yoke of custom meant simple lawlessness ; and against such disintegrating lawless- ness all the most formidable sanctions which society could devise were brought to bear. Hence the feeling of corporate responsibility is universal among primitive societies. “ Not only the mutilators of the Hermai, but all the Athenians— not only the violator of the rites of the Bona Dea, but all the Romans—are liable to the curse engendered; and so all through ancient history.” In such a stage of mental development, the community as a whole is beset with perpetual anxiety concerning the words and deeds of its members; and it is to a great extent from this sense of corporate responsibility that persecution for heresy in opinion or eccentricity in behaviour is ultimately derived, The inference from all these considerations is obvious. Tribes with the strongest sense of corporate responsibility, with the most rigid family-relationships, the most despotic yoke of custom, go on growing through long ages at the ex- pense of rival tribes in which the means for securing con- certed action over wide areas are less perfect. Age after age some competing tribes are exterminated or enslaved, while nthers are absorbed by the victorious tribe and assimilated to it; and thus age after age the bond of tyrannical custom becomes stronger and more rigid, while it extends over wider areas and constrains a larger number of people to uniformity of behaviour. Such a process will naturally result in the formation of a huge social “ aggregate of the first order,” as in Egypt, Assyria, China, Mexico, and Peru. The common sharacteristic of these civilizations of lower type is that their growth in size has been out of all proportion to their increase in structural heterogeneity. Though they may contain many cities, they contain nothing like the civic type a air: oH. XX.] CONDITIONS OF PROGRESS, 269 of social organization, as seen in Greece and Italy; and though they have taken on the semblance of nations, yet they lack the fundamental conception of true Nationality,— the union of individuals through community of interests, rather than through physical community of descent.t In all these half-civilized societies, we find that the prim‘tive tribal or patriarchal mode of structure is simply expanded without being essentially altered. The family is still the unit of society, the sense of corporate responsibility is still powerful, individual careers are still determined by status and not by contract, originality in opinion or in demeanour is still prohibited by the most formidable legal or social penalties ; the tyranny of custom, in short, is still paramount, and—to crown all—the three kinds of governmental agency, political, ecclesiastical, and ceremonial, are still concentrated in the person of the patriarchal ruler, who is at once king, chief-priest or vice-deity, and master of ceremonies. Observe, now, the dilemma which seems to confront us. In the operation of natural selection upon primitive tribes, we seem to have found a satisfactory explanation of the erowth of such social “ aguregates of the first order” as China or old Mexico. But now, how are we going to get past this stage? How shall we account for the forma- tion of social aggregates of a higher type? The problem now 1 In antiquity the only conceivable bond of social union was community of descent, actual or fictitious, Even the conception of territorial proximity as a source of common action did not gain currency in Europe till towards the tenth century of the Christian era. Theodoric the East-Goth, whom the old historians called “ King of Italy,” would not have understood the meaning of the phrase. In those days a man could be king of a group of kindred people, without reference to locality, but such a thing as kingship of a geo- graphical area was unintelligible. The modern nationality (of which the United States is perhaps the most perfect type) is founded upon the thorough subordination of the patriarchal theory of community in blood to the modern theory of community in interests. The so-called “doctrine of nationalities,” about which so much sentimental nonsense has been written, ought rather to be called the “doctrine of races,” since it is virtually a revival of the patri- archal theory. It may be truly said that, in spite of greater ethnic diversity, Switzerland, for example, is in many respects more completely a nationality than Spain. 270 COSMIC PHILOSOPHY. [pr. 11. before us is how to relax the tyranny of custom, and thus afford a chance for social reorganization, without entailing a retrogression toward primeval lawlessness. It is one of the puzzles of sociology that the very state of things which is pre-eminently useful in bringing men out of savagery is also likely to be pre-eminently in the way of their attaining to a persistently progressive civilization. ‘No one,” says Mr. Bagehot, “will ever comprehend the arrested civiliza- tions unless he sees the strict dilemma of early society. — Either men had no law at all, and lived in confused tribes, hardly hanging together, or they had to obtain a fixed law by processes of incredible difficulty. Those who surmounted that difficulty soon destroyed all those that lay in their way who did not. And then they themselves were caught in their own yoke. The customary discipline, which could only be imposed on any early men by terrible sanctions, con- tinued with those sanctions, and killed out of the whole society the propensities to variation which are the principle of progress.” * Mr. Bagehot shows that this problem has never been successfully solved except where a race, rendered organically law-abiding through some discipline of the foregoing kind, has been thrown into emulative conflict with other races simi- larly disciplined,—a condition which has been completely fulfilled only in the case of the migrating Aryans who settled Europe. But before we can extricate ourselves from our ‘seeming dilemma, we need to point out, more distinctly than Mr. Bagehot has done, that in all probability none of the progressive Aryan races has ever passed through any- thing corresponding to the Chinese or Egyptian stage, and that when a community has once got into such a state of fixity, it is really questionable whether it can ever get out of it, unless under the direct tuition of other communities. It would at present be premature to speculate upon the results which 1 Physics and Politics, p. 57. | cH. xx. ] CONDITIONS OF PROGRESS, 271 are likely to flow from British dominion in Hindustan, or from the intrusion of European ideas into Japan and China. Looking to the past only, it is safe to Say that when the “cake of custom” has become so firmly cemented, and on such a great scale, as in these primitively-organized commu- nities, there is but little likelihood of its getting broken. The Oriental stage—if one may so call it—is not a stage through which progressive nations pass, but it is a stage in which further progress is impossible, save through the occurrence of some deep-reaching social revolution. The progressive races are just those which have in some way avoided this dilemma,—which have succeeded in securing concerted action among individuals without going so far as to kill out the tendency to individual variations. Historically we find no traces of primitive political despotism among the European Aryans. Alike among Greeks, Italians, Teutons, and Slaves, we find the elements of a free constitution at hand, and the “age of discussion” inaugurated, at the very beginnings of recorded history. Though society is still constructed on the patriarchal type, there is nevertheless an amount of relative mobility among the social units such as is not witnessed eitler in Oriental despotisms or among modern savayes. I believe, tlierefore, that the character of the dilemma is somewhat inadequately represented by Mr. Bagehot. It is not quite true that in a progressive society the “cake of custom” must first be cemented as firmly as possible, and then after- wards broken. For when the cementing passes beyond a certain point, the breaking becomes impracticable. The dilemma consists rather in the fact that in a progressive society the cementing and the breaking of the “cake of custom” must go on simultaneously. Observe the seeming contradiction. While it is perfectly true that the power of concerted action on a large scale gives to the community possessing it a decided military advantage, and while it is true that in 272 COSMIC PHILOSOPHY. (er. m. early times this power of cooperation can hardly be gained save through the uniformity of discipline prescribed by tyrannical custom, it is also true that a considerable amount of individual variability is, even in early times, a source of military strength to the community. For in all stages of progress the law holds good that, in order to ensure a per- manent supply of first-rate individual excellence, whether in intellect or in character, there must be perpetual variation,— the members of the community must not all conform to precisely the same standard of belief or action. It is not simply that out of the conflict of opinions there comes an increase of mental power, but it is that where absolute uniformity of opinion is enforced, the very individuals most capable of serving the community by reason of superior mental power are neglected, thwarted, or killed off. The truth is not yet wholly trite that the most valuable men of every age are its heretics. For this truth is obscured by the kindred truth that the heresy of one age is the orthodoxy. of the next,—so that complacent orthodoxy, ignoring the historical point of view, is wont to claim as its allies to-day. the very men whom it burnt or crucified in days gone by. Obviously it is in the nature of things that this should be so. If old-established ideas were never to be unsettled, new truths would cease to find recognition, and progress would be at an end. But in any age the discoverers and promulgators of new truths are to be found only among those who possess the superior mental flexibility requisite for shaking themselves loose from the network of old- established ideas. And wherever there is such mental flexibility, there is sure to*be heresy. Above all is this true in early communities, for in these later times we have become so far accustomed to variations in belief and practice, and have so far substituted individual for corporate responsi- bility, that there is a great deal of variation which we do not count as heresy, but which formerly would have been oH. xx.] CONDITIONS OF PROGRESS. 273 regarded as such. Hence in an early community, the enforce- ment of absolute uniformity of belief and practice must establish a kind of natural selection tending to weed out all superior flexibility of mind. As a direct result the community closes up a prolific source of military superiority in the shape of individual political and military genius; for men of the Themistokles type are not produced, as a rule, in such states of society. The indirect result will be more fully appreciated when the next chapter has shown us how closely mental flexibility is implicated with that power of represent- ing objects and relations remote from sense which also underlies the invaluable power of anticipating future emer- gencies. To weed out superior flexibility of mind is to check further development in forethought or longheadedness, —a truth of which the entire history of the Oriental com- munities, so unlike each other in many respects, is one long and reiterated confirmation. Still further, when we recall the patent fact that the efficiency of any community is measured by the efficiency of its individual members, and that this efficiency is kept up by a kind of natural selection which is none the less potent for not working with the death: penalty as among lower animals, we shall realize how great is the military advantage entailed by free variation and com- petition. In illustration of all this we may recur to a historical event already cited for other purposes. When the Mede, whose laws were quoted as the very type of unchange- ableness, sought to add to his overgrown dominions the modest patrimony of the Athenian, of whom it was said that he was ever curious after new and unheard-of things, the wager of battle resulted in no doubtful verdict. When it is asked how Miltiades, with his ten thousand, could so quickly put to flight Datis, with his hundred thousand, the unhesitating reply is that the result was due to the superior social organization under which the ten thousand were reared. But this superiority of organization consisted mainly in the VOL. IT, T 4 274 COSMIC PHILOSOPHY. [pr. 1 fact that the individual career of the Mede wats prescribed by unvarying tradition, while the maxim upon which the Athenian implicitly acted was La carriére ouverte aux talents, These are some of the military advantages of Mr. Bagehot’s “age of discussion.” But in truth they are advantages which do not belong exclusively to any age or to any epoch of development, but are operative at all times, though in dif- ferent ages and communities their action is diversely com- plicated with the action of the opposite advantages previously © considered. Mr. Bagehot’s error—if it be real and not mcrely apparent—lies in describing as purely successive circum- stances which must have been in great degree simultaneous. The “strict dilemma of early society” is not that the fetters of tyrannical custom must first be riveted and afterwards unriveted, but that they must be riveted and unriveted at the same time in communities which are destined to attain to permanent progressiveness. On the one hand we have seen that primitive societies in which uniformity of belief and practice is most sternly enforced, will prevail in the struggle for life. On the other hand we have seen that primitive societies in which flexibility of mind is most encouraged, will come out uppermost. And herein lies the seeming dilemma or contradiction. In reality, however, as the whole question is one of war- fare, so it is practically a struggle for life between these two principles. Into the numberless combinations of circum- stances which have given the victory now to one side and now to the other, we cannot inquire, from lack of historical data. On general grounds we may admit that, at the outset, uniformity must have been a more important possession than flexibility ; we can plainly see how those communities that conquered by means of uniformity became caught, as it were, in their own toils, and were estopped from further progression; and we can see how those communities that won the day by preserving a modicum of flexibility have on. xx. | CONDITIONS OF PROGRESS. 275 been rewarded by unlimited progressiveness. We can thus dimly discern the way in which China kas become immobile, while Europe has become ever more and more mobile. But beyond these most general indications of what has happened, we can discern but little. We cannot tell precisely, for example, why the European Aryans won the day by preserv- ing a modicum of flexibility, rather than by enforcing such a monotony of disposition as would kill out all flexibility. At the earliest dawn of history the European portion of the Aryan race already surpasses all other races, both in individual variety of character and in longheadedness. The details of the process by which this superiority was gained are hidden from us in the night of time. Upon one point, however, we may profitably speculate. Among all the historic civiliza- tions, the European is the one of which we can most de- cidedly assert that it is not autochthonous. The Aryans who conquered Europe in successive Keltic, Italo-Hellenic, Teutonic, and Slavonic swarms, were not the quiet, conser- vative, stay-at-home people of prehistoric antiquity, but were rather the elect of all the most adventurous and flexible-minded portions of the tribally-organized population of Central Asia. Their invasion of Europe was in this respect like the subsequent invasion of England by the mis- cellaneous hordes roughly described as Angles and Saxons, Danes and Norinans, and like the still later colonization of North America by the most mobile and adventurous elements of West-European society. We may fairly suppose that the Aryan. invaders of Europe were the most supple-minded of their race,—che “ come-outers,” perhaps, for whom the cake of custom at home was getting too firmly cemented, but who had undergone sufficient social discipline to enable them to get along with a less solid cake in future. However this may be, the main point is that they were not aborigines but colonizers, and as such were subjected to a great hetero geneity of environing circumstances from the time when we tT 2 276 COSMIC PHILOSOPHY, (PT. 11 first catch sight of them. They were the pioncers or Yankees of prehistoric antiquity, in whom unusual flexibleness of mind was the natural result of continual change in the sets of relations to which they were obliged to make their theories and actions conform. Prehistoric antiquity presents no other case like this. The great immobile civilizations appear to have grown up in comparatively well-protected regions, where competition with outlying communities was checked at an early date. Screened in this way from intercourse with the outside world, and adapting themselves to an en- vironment which altered. but little, there was nothing which could serve to shake them loose from their monotony of discipline. A more extreme instance of a kindred pheno- menon is seen in the fact that in those protected corners of the world where competition has always been at a mini- mum; we find the smallest conceivable amount of progress from utter bestial savagery. That same isolation which has kept the flora and fauna of Australia in such a backward state that they are now melting away before the imported plants and animals of Europe as snow melts under a vernal sun,—that same isolation has retained the Australian man until this day at the lowest level of humanity. Similar things might be said of the Fuegians, the Andaman Islanders, and some of thie hill-tribes of aboriginal non-Aryan Hindus. Where there has been least competition and least natural selection, there has been least progress from savagery. Now returning to the immobile civilizations, when we bear in mind that of the two conflicting elements of military advantage, uniformity was likely to be of most importance at first and flexibility afterwards, we may begin to discern, I think, that where competition ceased at an early date, uniformity may well have carried the day and crushed out flexibility alto- gether. Herein we have an excellent explanation of the immobility of Egypt, China, Peru, and Mexico; and with some further qualiticatious an analogous case might be made a le ou. XXx.] CONDITIONS OF PROGRESS. 277 out for Assyria and Northern India, But no such early cessation of competition could have oceurred in the case of our Aryan forefathers. Little as we know concerning the circumstances of their prehistoric development, we know at least that it took place on the great highway between the teeming mainland of Asia and the coveted peninsula of Europe. In this swarming region there was kept up until quite recent times that intense competition of tribe with tribe which had all but died out in Evypt and China before the dawn of history. All this entailed for each winning tribe a greater heterogeneity of environment than in any other instance. Under such circumstances uniformity could hardly have carried the day so far as to crush out flexibility. Continual change of foes to be overcome, and of natural obstacles to be surmounted, must have given the advantage at last to those tribes which had gained enough uniformity to ensure concerted action, without sacrificing their versatility of mind in the process. To some such considerations as these we must look for the partial explanation of the fact that at the beginnings of recorded history we find in the European Aryans all the essential elements of progressiveness. The continuance of this progressiveness during the historic period is a fact which need not long detain us. Since the beginnings of Mediter- ranean Civilization, the heterogeneity of the environment has been too gréat, and the changes in the environment too rapid, to allow of general staguation; while the assaults of outer barbarism have been for the most part warded off by the military superiority which this higner civilization has en- tailed. At times there has been an appearance of danger that much of this hard-won advantage might be lost, not merely through assaults from without, but through causes internally operating, After the earlier incentives to noble and varied activity connected with the autonomous spirit had been destroyed by the universal hegemony of Rome, the 278 COSMIC PHILOSOPHY. (pr. a, need for protection from the threatening barbarian began to bring about a retrogression, in which for a time uniformity seemed likely to flourish at the expense of individuality. It is instructive, from this point of view, to observe the gradual change toward an Oriental type of government which went on from the time of Augustus to that of Diocletian. In the eastern half of the Empire, after its final political severance from the western half at the end of the eighth century, this change became really consummated, and after a while de- feated itself by culminating in a social stagnation and mili- tary feebleness which invited the sharp scimitar of the Mussulman. But in the West this fatal growth of patri- archal despotism was early checked by the rise of Chris- tianity as an independent spiritual power, by the immigration of the German tribes, and by the union of these two circum- stances. Iurope was in no immediate danger of lapsing into an Oriental condition when an Ambrose could say to a Theodosius, “ Thus far shalt thou go and no farther.” The German tribes, by their direct coalescence into national ageregates, without passing through the civic stage of organi- zation, furnished, in various degrees of completeness, the principles of representation and federation, thus adding im- portant elements of new life to the Empire. While finally the Christianization of these tribes, leading to the famous compact by which the Head of the Church transferred the lordship of the western world from the degenerate Byzantine to the strong-armed Frank, inaugurated a balance of powers which preserved Europe henceforth from any danger of be- © coming either a sultanate or a caliphate. In this twofold supremacy of Church and Empire during the Middle Ages, we have one of the most remarkable compromises be- tween antagonist forces known to history ; for while the ten- dency of either set of forces acting alone would have been ‘toward absolute despotism, either in the spiritual or in the temporal form, on the other hand their joint action and ci, xx.] CONDITIONS OF PROGRESS. 279 counter-action was in a high degree conducive to the develop- ment of individual liberty of thought and behaviour. The various hints here given thus combine to show how, both in historic and in prehistoric times, the European Aryans would seem to have profited by circumstances tend- ing to encourage individuality without weakening concentra- tion. Hence the peculiarly plastic consistency—the flexibility combined with toughness—of West-Aryan civilization. Hence the European races all possess the capacity of innovating without revolution. The English and the old Romaus have exhibited this capacity in the highest degree; the Spaniards and the French, in recent times, owing to previous reversion toward a despotic réime, have shown themselves partially deprived of it. But while it is thus manifested in quite various degrees, all alike possess it in a high degree as compared with those races which have been arrested in the Oriental stage of civilization. The successful achievement of innovation without revo- lution depends mainly upon an artifice which derives its validity from one of the most deep-seated tendencies of the human mind, and which has unquestionably been one of the chief agencies in forwarding social progress. I refer to the artifice of “ legal fiction,” as shown in the pretence that the novelty of belief or practice just inaugurated has its warrant in time-honoured precedent. The disposition to justify all innovation by means of this artifice is so strongly rooted in human nature that it is likely to be manifested for a long time to come,—probably until the millennial victory of that “ pure reason ’ chout which sentimental philosophers have prated, but which hitherto has played a very subordinate part in shaping human affairs, It is this disposition which leads the orthodox, after resisting some scientific heresy until resistance is no longer possible, to discover all at once that the heresy was really taught by Suarez, or St. Augustine, or Moses. It is this which enables changes to be made “ constitutionally,” or 280 COSMIC PHILOSOPHY. [wr. 11, in accordance with a system of edicts framed in an age when the changes in question could not possibly have been con- templated or proviced for. Yet among ourselves, where the dread of novelty is comparatively slight, there is some difficulty in realizing how all-essential is this kind of artifice in early times. “To this day many semi-civilized races have great difficulty in regarding any arrangement as binding and conclusive unless they can also manage to look at it as an inherited usage. Sir Henry Maine, in his last work, gives a most curious case. The English Government in India has in many cases made new and great works of irrigation, of which no ancient Indian Government ever thought; and it has generally left it to the native village community to say what share each man of the village should have in the water; and the village authorities have accordingly laid down a series of most minute rules about it. But the peculiarity is, that in no case do these rules ‘ purport to emanate from the personal authority of their author or authors, which rests on grounds of reason, not on grounds of innocence and sanctity ; nor do they assume to be dictated by a sense of equity; there is always, I am assured, a sort of fiction under which some customs as to the distribution of water are supposed to have emanated from a remote antiquity, although, in fact, no such artificial supply had ever been so much as thought of’ So difficult does this ancient race—like, probably, in this respect so much of the ancient world—tind it to imagine a rule which is obligatory, but not traditional,” ? Now among the European Aryans, within historic times, this species of artifice assumed a form which made it in a very high degree conducive to the permanent progressiveness of the race. If we look into the great writers who in the seventeenth century illustrated with exquisite beauty and clearness the doctrines of Public Law, we find their heads filled with the notion of a primitive natural code, fit for 1 Bagehot, Physics and Politics, p. 142 cH. Xx. ] CONDITIONS OF PROGRESS. 281 regulating international concerns, and for supplying every- where the shortcomings of civil legislation, its degenerate offspring, whose worth must be rated according to the degree in which it approaches the perfection of its parent. The influence of this conception may be best appreciated by reflecting on the extent to which contemporary legal literature, whether embodied in expository treatises or in judicial deci- _ sions, is impregnated by it. The appeals to “:zight reason” and “natural reason” which since Blackstone’s time have filled a considerable place in juristic dissertation, bear un- _ equivocal marks of their origin. Nowhere better than here can we see exemplified the mighty influence of the ideas of Roman jurisprudence upon modern thought. Sir Henry Maine has well delineated the process by which, from the constantly felt want of a system of principles fit for settling disputes between Roman citizens and aliens or foreigners, there gradually arose in the Preetorian courts an equitable body of law founded upon customs common (or assumed as common) to all peoples alike. But far from comprehending the really progressive character of the noble juristic system steadily growing up under their own supervision—daily attaining grander proportions as the grotesque and barbarous elements hallowed by local usage were one-by one eliminated from the body of equitable ideas which formed their common substratum—the Pretors of the Republic and the great Antonine jurisconsults, under the immediate influence of Stoic conceptions, supposed themselves to be merely restoring to their original integrity the disfigured and partially obliterated ordinances of a primeval state of nature. The state of faultless morality and unimpeachable equity which constituted the ideal goal of their labours, they mistook for the shadow of a real though unseen past. But this form of the unconscious artifice—due in general to the great heterogeneity of the Roman environment, and in particular to the continual interaction between Greek and 282 | COSMIC PHILOSOPHY. (pr. 1 Roman ideas—was very different from the form of it ex- emplified by the Hindu who refers his modern edicts about water-supply to some remote era of primitive legislation. Between the two there is a world-wide difference,—all the difference between stagnation and progress. For the abstract and impersonal form in which the Roman conceived his Jus Nature made it possible for him to appeal to it, not simply in justification of particular departures from ancient custom, but in justification of the general principle of departure from ancient custom. It constituted, as it were, a court of appeal before which time-honoured customs must be called upon to establish their validity. It opened men’s minds to the distinction between mala prohibita and mala in se. It prepared the way for the recognition of a “higher law ” of God as distinct from the local and temporary laws of man. And in this way it no doubt contributed largely toward the establishment of Christianity as an independent spiritual power in the Empire. : To deal adequately with these interesting illustrations would require us to extend this part of our discussion to disproportionate length, Our purpose is sufficiently sub- served by the foregoing fragmentary statement, in which the problem of human progressiveness, though not fully solved, is at least so far classified that the solution of it is facili- tated. We have seen that permanent progressiveness is found where the social aggregate is characterized by a cohe- | sion among its parts which is neither too little nor too great. An excess and a deficiency of individual mobility have been shown to be alike incompatible with that persistent tendency toward internal rearrangement which we call progressiveness. The sociological puzzle to which Mr. Bagehot has called attention, and with which we have been concerned in the present chapter, is substantially the same thing as the dynamic paradox which confronted us when, in the fourth chapter, we were secking to determine the conditions which’ - OH. XX.] CONDITIONS OF PROGRESS. 283 enable Evolution in general to result in continuous increase of structural and functional complexity. The present case is, indeed, but a special form of the more general case. How to secure a compromise between fluidity and rigidity is in both cases the essential desideratum. Where the units which make up the aggreeate have too much individual freedom of motion, the result is a fluid state in which there is no chance for stable structural arrangements. Where they have too little freedom of motion, the result is a solid state in which there is no chance for structural rearrangements. In the first case, where there is so little dissipation of motion, there is little or no Evolution. In the second case, where so little internal motion is retained, the Evolution which occurs is simply or chiefly a process of consolidation, unattended by any considerable advance from indeterminate uniformity toward determinate muitiformity. Bearing in mind that we are dealing, not with a mere series of striking analogies, but with a group of real resem- blances which result from a fundamental. homology between the special process here considered and the more general process which includes it, let us observe that one chief cir- cumstance which secures mobility without loss of coherence is a he'erogeneous and ever-changing social environment, to the heterogeneous changes of which the community is con- tinually required to adjust itself. The illustrations above given unite in showing that where circumstances have afforded such a heterojeneous environment (as a perpetual external excitant of internal rearrangements), the commu- nities which have survived through relatively-complete ad- ,ustment have manifested a permanent capacity for progress. Thus is our problem completely connected with the more general problem of natural selection, and with the most general problem of Evolution as manifested in all orders of phenomena. And thus the essential continuity of the pro- cesses of Nature is again strikingly illustrated, 284 COSMIC PHILOSOFAY,. [Pr. 11. In the following chapter we shall have frequent oveasion to refer to this circumstance of heterogeneity of the social environment as manifested psychologically, in its effects upon the intellectual mobility of men regarded as indi- viduals. To pursue the problem of progressiveness into this psychological region is the way in which to obtain a basis for the explanation of the progress from Brute to Man; and to this crowning inquiry we must now address ourselves ; ; ’ j Py : CHAPTER XXL GENESIS OF MAN, INTELLEC-UALLY. Tur chief difficulty which most persons find in accepting the Doctrine of Evolution as applied to the origin of the human race, is the difficulty of realizing in imagination the kinship between the higher and the lower forms of intelligence and emotion. And this difficulty is enhanced by a tendency of which our daily associations make it hard to rid ourselves. There is a tendency to exaggerate the contrasts which really exist, by leaving out of mind the intermediate phenomena and considering only the extremes. Many critics, both among those who are hostile to the development theory and among those who regard it with favour, habitually argue as if the intel- ligence and morality of the human race might be fairly represented by the intelligence and morality of a minority of highly organized and highly educated people in the most civilized communities. "When speaking of mankind they are speaking of that which is represented to their imagination by the small number of upright, cultivated, and well-bred people with whom they are directly acquainted, and also to some extent by a few of those quite exceptional men and womer who have left names recorded in history. Though other elements are admitted into the conception, these are never- theless the ones whicn chiefly give to it its character. Employing then this conception of mankind, abstracted from 286 COSMIC PHILOSOPHY, [pr. 1. these inadequate instances, our critics ask us how it is possible to imagine that a race possessed of such a godlike intellect, such a keen wsthetic sense, and such a lofty soul, should ever have descended from a race of mere brutes. And again they ask us how can a race endowed with such a capacity for progress be genetically akin to those lower races of which even the highest show no advance from one genera- tion to another. Confronted thus by difficulties which reason* and imagination seem alike incompetent to overcome, they too often either give up the problem as insoluble, or else— which amounts to nearly the same thing—have recourse to the deus ex machind as an aid in solving it. Influenced, no doubt, by some such mental habit as this Mr. St. George Mivart declares that, while thoroughly agree- ing with Mr. Darwin as to man’s zoological position, he nevertheless regards the difference between ape and mush- room as less important than the difference between ape and man, so soon as we take into the account “the totality of man’s being.”! In this emphatic statement there is a certain amount of truth, though Mr. Mivart is not justified in imply- ing that it is a truth which the Darwinian is bound not to recognize. The enormous difference between civilized man and the highest of brute animals is by no one more emphati- cally recognized than by the evolutionist, who holds that to the process of organic development there has been super- added a stupendous process of social development, and who must therefore admit that with the beginning of human civilization there was opened a new chapter in the history of the universe, so far as we know it. From the human point of view we may contentedly grant that, for all practical purposes, the difference between an ape and a mushroom is of less consequence than the difference between an ape and an educated European of the nineteenth century. But to take this educated European as a typical sample of mankind 1 Nature, April 20, 1871. on. xx1.] GENESIS OF MAN, INTELLECTUALLY, 287 and to contrast him directly with chimpanzees and gibbons, is in the highest degree fallacious; since the proceeding involves the omission of a host of facts which, when taken into the account, must essentially modify the aspect of the whole case. When we take the refined and intellectual Teuton, with his one hundred and fourteen cubic inches of brain, and set him alongside of the chimpanzee with his thirty-five cubic inches of brain, the difference seems so enormous as to be incom- patible with any original kinship. But when we interpose the Australian, whose brain, measuring seventy cubic inches, comes considerably nearer to that of the chimpanzee than to that of the Teuton, the case is entirely altered, and we are no longer inclined to admit sweeping statements about the immeasurable superiority of man, which we may still admit, provided they are restricted to civilized man. If we examine the anatomical composition of these brains, the discovery that in structural complexity the Teutonic cere- brum surpasses the Australian even more than the latter surpasses that of the chimpanzee, serves to strengthen us in our position. And when we pass from facts of anatomy to facts of psychology, we obtain still further confirmation ; for we find that the difference in structure is fully paralleled by the difference in functional manifestation. If the English- man shows such wonderful command of relations of space, time, and number, as to be able to tell us that to an observer stauioned at Greenwich on the 7th of June, a.p. 2004, at precisely nine minutes and fifty-six seconds after five o’clock in the morning, Venus will begin to cross the sun’s disc; on the other hand, the Australian is able to count only up to five or six, and cannot tell us the number of fingers on his two hands, since so large a number as ten excites in him only an indefinite impression of plurality. Our conception of 1 The Dammaras, according to Mr. Galton, are even worse off than this. “When they wish to express four, they take to th:ir fingers, which are to 2388 COSMIC PHILOSOPHY. [pr. 1h the godlike intellect evidently will not apply here. If the emotions of the German and his intellectual perceptions of the fitness of harmonious sounds for expressing emotion are so deep and subtle and varied as to result in the production of choruses like those of Handel and symphonies like those of Beethoven, on the other hand the crude emotions of the Australian are quite adequately expressed by the discordant yells and howls which constitute the sole kind of music ap- preciable by his undeveloped ears. We look in vain here for traces of the keen esthetic sense which in a measure links together our intellectual and moral natures. Again, if the American student has been known to be actuated by such noble ethical impulses and guided by such lofty conceptions of morality as to leave his comfortable home and his them as formidable instruments of calculation asa sliding rule is to an English school-boy. They puzzle very much after five, because no spare hand reinains to grasp and secure the fingers that are required for units. Yet they seldom lose oxen; the way in which they discover the loss of one is not by the number of the herd being diminished, but by the absence of a face they know. When bartering is going on, each sheep must be paid for separately. Thus, suppose two sticks of tobacco to be the rate of exchafige for one sheep, it would sorely puzzle a Dammara to take two sheepand give him four sticks. I have done so, and seen a man put two of the sticks apart, and take a sight over them at one of the sheep he was about to sell. Having satisfied himself that that one was honestly paid for, and finding to his surprise that exactly two sticks remained in hand to settle the account for the other sheep, he would be aiflicted with doubts; the transaction seemed to come out too ‘pat’ to be correct, and he would refer back to the first couple of sticks; and then his © mind got hazy and confused, and wandered from one sheep to the other, and he broke off the transaction until two sticks were put into his hand, and one sheep driven away, and then the other two sticks given him, and the second sheep driven away. . . . Once while I watched a Dammara floundering hopelessly in a caleulation on one side of me, I observed Dinah, my spaniel, equally embarrassed on the other. She was overlooking half-a-dozen of her new-born puppies, which had been removed two or three times from her, and her anxiety was excessive, as she tried to find out if they were all present, or if any were still missing. She kept puzzling and running her eyes over them, backwards and forwards, but could not satisfy herself. She evidently had a vague notion of countiug, but the figure was too large for her brain. Taking the two as they stood, dog and Dammara, the comparison reflected no great honour on the man.”—Galton, Tropical South Africa, p. 132, cited in Lub- bock, Origin of Civilization, Amer. ed., p. 294.

For although, like some brute animals, he is not wholly destitute of the primary feelings which underlie them, yet these feelings have been so seldom re- peated in his own experience, and that of his ancestors, that he is unable to generalize from them. The lofty soul, which is too sweepingly attributed to man in distinction from other animals, is here as difficult to discover as the godlike intellect or the keen esthetic sense. In similar wise is made to disappear the sharp contrast between human and brute animals in capability of progress. Hardly any fact is more imposing to the imagination than the fact that each generation of civilized men is perceptibly more enlightened than the preceding one, while each genera- _ tion of brutes exactly resembles those which have come before it. But the contrast is obtained only by comparing the civilized European of to-day directly with the brute animals known to us through the short period of recorded human history. The capability of progress, however, is by no means shared alike by all races of men. Of the numerous races historically known to us, it has been manifested in a marked degree only by two,—the Aryan and Semitic. To a much less conspicuous extent it has been exhibited by the Chinese and Japanese, the Copts of Egypt, and a few of the highest American races. On the other hand, the small-brained races —the Australians and Papuans, the Hottentots, and the majority of tribes constituting the widespread Malay and American families—appear almost wholly incapable of pro- gress, even under the guidance of higher races. The most VOL, IL v 220 COSMIC PHILOSOPHY. [rr 1 that can be said for them is, that they are somewhat more imitative and somewhat more teachable than any brute animals. In the presence of the Aryan, even under the most favourable circumstances, they tend to become extin- guished, rather than to appropriate the results of a civiliza- tion which there is no reason to suppose they could ever have originated. The two great races of Middle Africa, the Negroes and the Kaffirs,! have shown, by their ability to endure slave labour, their superiority to those above men- tioned; but their career, where it has not been interfered with by white men, has been but little less monotonous than the career of a brute species. Of all these barbarian races, we commonly say that they have no history; and by this we mean that throughout long ages they have made no appreciable progress. In a similar sense we should say of a race of monkeys or elephants, that it has no history. Of like import is the fact, that as we go backward in time we find the progressiveness of the civilized races continually diminishing. No previous century ever saw anything ap- proaching to the increase in social complexity which has been wrought in America and Europe since 1789. In science and in the industrial arts the change has been greater than in the ten preceding centuries taken together. Contrast the seventeen centuries which it took to remodel the astronomy of Iipparchos with the forty years which it has taken to remodel the chemistry of Berzelius and the biology of Cuvier. Note how the law of gravitation was nearly a century in getting generally accepted by foreign astronomers,? while 1 Tt is Haeckel who asserts a distinction of race between the Negroes and Saffirs. It is not necessary, however, to insist upon the distinction. 2 It was still on trial in France in 1749, when Clairaut and Lalande mag- nificently verified it by calculating the retardation of Halley’s comet. It may be said that the French are notoriously slow in adopting ideas which have originated in other countries, and that they now ignore natural selection much as they formerly ignored gravitation. Nevertheless, in spite of the Academy and M. Flourens, there are plain indications that the doctrine of special creations is doomed speedily to suffer the fate in France which it has ready suffered in Germany, England, and America. it ae on. xx1.] GENESIS OF MAN, INTELLECTUALLY. 291 within half a dozen years from its promulgation, the theory of natural selection was accepted by the great majority of naturalists. How small the difference between the clumsy wavvons of the Tudor period and the mail-coach in which our grandfathers rode, compared to the difference between the mail-coach and the railway train! How rapid the changes in philosophic thinking since the time oz the Hncy- ' ¢elopédistes, in comparison with the slow though important changes which occurred between the epoch of Aristotle and the epoch of Descartes! In morality, both individual and national, and in genera] humanity of disposition and refine- ment of manners, the increased rapidity of change has been no less marked. & But these-considerations are immensely increased i in force when we take into account those epochs which, in the light of our present knowledge, can alone properly be termed ancient, Far beyond the comparatively recent period at which human history began on the eastern shores of the Mediterranean, extend the ages during which, as palzon- tology shows us, both the eastern and the western hemi- spheres were peopled by races of men. Ten thousand cen- turies before the time of Homer and the Vedic poets, wild men, with brute-like crania, carried on the struggle for existence with mainmoths, tigers, and gigantic bears, Jong since extinct. And recent researches make it probable that even this enormous period must be multiplied six- or eight- fold before we can arrive at the time when men first ap- peared upon the earth as creatures zoologically distinct from apes. The significance of these conclusions, even when we take into account only the shorter epoch of a single million of years, cannot be too strongly insisted upon, They show us that it is only in recent times that man has become widely distinguished from other animals by his capability of -progress. If, as evidence of our present progressiveness, we city the superiority of our Whitworth guns and Chassepot U 2 Z92 COSMIC PHILOSOPHY. (Pr. 11 rifles over the howitzers and flintlocks used by our grand- fathers, we must also remember that more than twenty thousand generations lived and died before the primitive stone hatchets and stone-pointed arrows were superseded by battle-axes and javelins headed with bronze. During these long ages, each generation must have imitated its predecessor almost as closely as is the case with brute animals. The godlike intellect, of whose achievements we are now so justly proud, was then being acquired by almost © infinitely minute increments. In the face of the proved fact of man’s immense antiquity, no other conclusion is admissible. I have introduced these considerations, not so much to confirm the theory of the descent of man from an ape-like animal,—which I regard as already sufficiently proved by the evidence presented in the ninth chapter,—as to illustrate the true point of view from which the evolution of humanity should be regarded. In treating of the Doctrine of Evolution in general, we saw it to be a corollary from the persistence of force that the process of evolution, which at first goes on with comparative slowness, must, owing to the multiplication of effects, go on with increasing rapidity.1 We have seen, besides, that those most conspicuous aspects of evolution which consist in increase of definite complexity in structure and function must be much more conspicuous in the more compound than in the more simple kinds of evolution. In illustration of these closely allied truths, we may note that in all cases a long period of time elapses before any lower order of evolution gives rise to a distinctly higher order. Long ages must have passed before the slow integration of our solar nebula into a planetary system resulted in the appearance of distinctly geologic phenomena upon the several planets, Again, it was a long time before geologic 1 See above, vol. i. p. 854. This was also hinted st the close of the enapter on Life as Adjustment, cn, xx1.]} GENESIS OF MAN, INTELLECTUALLY. 293 evolution had proceeded sufficiently far to admit of the evolution of life: upon Saturn and Jupiter, as we have seen, the genesis of anything like what we know as life would appear still to be impossible. Again, after the first appear- ance of life upon our earth, a long time must have elapsed before protists, simple plants, and nerveless animals, were succeeded by animals sufficiently complex to manifest even the most rudimentary phases of psychical life. And again, as we can now see, the evolution of physical and psychical life to the very high degree exemplified in the primeval ape-like man, was ‘followed by a somewhat long period, during which the still higher psychical changes constituting social evolution ‘were slowly assuming their distinctive characteristics. Social evolution, therefore, Rabie as a complicated series of intellectual and emotional changes determined by the aggregation of men into communities, is a new order of evolution, more highly compounded than any that had gone before it. When, in the course of the struggle for existence, men began to unite in family groups of comparatively per- manent organization, a new era was begun in the progress of things upon the earth’s surface. A new set of structural and functional changes began, which for a long while pro- ceeding with the slowness characteristic of the | early stages of every order of evolution, are at last proceeding with a rapidity only to be slackened when some penultimate stage of equilibrium is approached. Hence it is in the highest degree unphilosophical to attempt to explain the present position of civilized man solely by reference to the laws of organic and psychicai evolution as obtained by the study of life in general. It is for biology to explain the differences between the human hand and foot and the hands and feet cf the other primates;+ but the chief differences between civilized man and the other members of the order to which 2 See Prof. Huxley’s admirable monograph on Man’s Place in Nature. 294 COSMIC PHILOSOPHY. {rr. “t he belongs are psychological differences, and the immense series of psychical changes to which they are due has been all along determined by social conditions. The all-important contrast. therefore—for our present pur- pose—is not between man ant other primates, extinet and contemporary, but between civilized man and primitive man. Already we have found that the lowest contemporary man, whose social organization has never reached any higher form than that of the simplest tribal community, exhibits but scanty traces of the godlike intellect, the refined tastes, or the lofty soul which we are accustomed to ascribe to humanity in general as its distinctive attributes. Humanity, zoolo- gically considered, exists to-day, to which these attributes cannot be ascribed without a considerable strain upon the accepted meanings of our words. Zoologically, the Australian belongs to the genus Hoino, and is therefore nearer to us than to the gorilla or gibbon; psychologically, he is in many respects further removed from us than from these man-like apes. No one will deny that the intellectual progress implied in counting up to five or six, though equally important, is immeasurably inferior in quantity to the subsequent progress implied in the solution of dynamical problems by means of the integral caleulus,—an achievement to which the average modern engineer is competent. But im going back to the primeval man, we must descend to a lower grade of intelli- gence than that which is oceupied by the Australian. We must traverse the immensely long period during which the average human skull was enlarging from a capacity of thirty-. five inches, like that of the highest apes, to a capacity of seventy inches, like those post-glacial European skulls, of which the one found at Neanderthal is a specimen, and which are about on a par with the skulls of Australians. And when we have reached the beginning of this period—possibly in the Miocene epoch—we may fairly represent. to ourselves the individuals of the human genus as animals differing in cn. xxi.) GHNESIS OF MAN, INTELLECTUALLY, 295 little save a more marked sociality from the dryopithecus and other extinct half-human apes. We may represent primitive man as an animal in whom, physical and psychical changes having hitherto proceeded pari passu, intelligence had at length arrived at a point where variations in it would sooner be seized on by natural selection than variations in physical structure. When among primates possessed of such an intel- ligence, the family groups temporarily formed among all mammals began to become permanent, then we must say that there began the career of humanity as distinguished from animality. For countless ages our ancestors probably were still but slightly distinguished from other primates, save that their increasing intelligence, their use of weapons, and their habits of combination, rendered them more than a match for much larger and stronger animals. In the later Pliocene times these primitive men may have come to bear some resem- blance to the lowest contemporary savages. Human remains and relies of the still later glacial period supply clear proof of such a resemblance ; yet the absence of any improvement in weapons and implements for many ages longer shows that as yet there was but little capability of progress. Of the career of mankind during the eight hundred thousand years which would seem to have elapsed since the era of the cave bear and woolly rhinoceros,! we possess many vestiges. But every- 1 In assigning this conjectural date, I follow the theory which connects the great glacial epoch with that notable increase in the eccentricity of the earth’s orbit which, as calculated by Mr. Croll, began about 950,0C0 years B.c., and lasted 200,000 years. But while the fact of this great increase of eccen- tricity is, I presume, well established, and while it can hardly fail to have wrought marked climatic changes, it is by no means proved that the glaciation of Europe and North America was produced. solely or chiefly by this circum- stance ; and accordingly I dv not care to insist upon the chronology which I have adopted in the text. Nor is it necessary for the validity of my argu- ment that. it should be insisted on. What we do know is, that men existed both in Europe and in North America at the beginning of the ylacial period ; that this extensive dispersal implies the existence of the human race for a long time previous to this epoch ; and that thus we obtain a dumb antiquity im comparison with which the whole duration of the voice of historic tradition shrinks to a mere point of time, And this is all that my argument requires. 296 COSMIC PHILOSOPAY, [rr. 1 thing indicates the most extreme barbarism; nowhere does there appear a trace of anything like even the rudest civiliza- tion, until we reach that comparatively recent epoch ante- cedent to the dawn of history, but accessible to philology, The partial restoration of the Aryan mother-tongue enables us to go back perhaps a dozen or fifteen centuries beyond the age of Homer and the Vedas, and catch a few glimpses’ of the prehistoric Aryans,—an agricultural race completely tribal in organization, but acquainted with the use of metals, and showing marks of an intelligence decidedly above that of high contemporary barbarians like the Kaffirs. At the same time the deciphering of hieroglyphics on Egyptian monuments reveals to us the existence in the valley of the Nile of an old and immobile civilization, organized on a tribal basis, like that of China, already sinking in political decrepitude at the ill-defined era at which we first catch sight of it. Of the beginnings of civilization on the Nile, and also, indeed, on the Euphrates, and of the stages by which the Aryans arrived at the intellectual pre-eminence to which their recovered language bears witness, we know abso- lutely nothing. But even if we were to allow twenty thousand years for these proceedings,—an interval nearly seven times as long as that which separates the Homeric age from our own time—we should obtain but a brief period compared with the countless ages of unmitigated barbarism which preceded it. The progress of mankind is like a geo- metrical progression. For a good while the repeated doubling produces quite unobtrusive results ; but as we begin to reach the large numbers the increase suddenly becomes astonishing. Since the beginning of recorded history we have been mov- ing among the large numbers, and each decade now witnesses a greater amount of psychical achievement than could have been witnessed in thousands of years among pre-glacial men, Such a.result is just what the Doctrine of Evolution teaches usto anticipate ; and it thoroughly confirms our statement on. xx1.] GENESIS OF MAN, INTELLECTUALLY. 297 that, in point of intelligence and capacity for progress, the real contrast is not between all mankind and other primates, but between civilized and primeval man. Let us now consider some of the leading characteristics of this gradual but increasingly rapid intellectual progress, reparded as a growing correspondence betaten the human mind and its environment. In the second chapter of our Prolegomena it was shown that the highest kinds of scientific knowledge differ only in fleeree from the lowest kinds of what is called ordinary knowledge. In spite of their great differences in mental capacity, it is obvious that the antelope who on hearing a roar from the neighbouring thicket infers that it is high time to run for his life, the Bushman who on seeing the torn carcass of the antelope infers that a lion has recently been present, and the astronomer who on witnessing certain unfore- seen irregularities in the motions of Uranus infers that an unknown planet is attracting it, perform one and all the same kind of mental operation. : In the three cases the processes are fundamentally the same, though differing in complexity. according to the number and remoteness of the past and present relations which are compared. In each case the. process is at bottom a grouping of objects and of relations: according to their likenesses and unlikenesses. It was similarly shown that all knowledge is a classification of: experiences, and that every act of knowledge is an act of. classification ; that. an act of inference, such as: is involved in simple cases of perception, is “ the attributing to a body, in consequence of some of. its properties, all those properties by virtue of which it is referred to a particular class”; that the “forming of a generalization is the putting together in one class all those cases which present like relations”; and that “the drawing a deduction is essentially the perception thata particular case belongs to a certain class of cases previously generalized. So that, as ordinary classification is a grouping 298 COSMIC PHILOSOPHY. [er 1 together of like things ; reasoning is a grouping together of like relations among things.”+ In this fundamental doctrine the two different schools of modern psychology, represented respectively by Mr. Bain and Mr. Mansel, will thoroughly agree. But from this it inevitably follows that the highest and the lowest manifestations of intelligence consist: respectively of processes which differ only in heterogeneity and definite-. ness and in the extent, to whicl: they are compounded. But while proving that science is but an extension of or- dinary knowledge, it was also proved that: the higher orders of knowledge differ from the lower in the greater remoteness, generality, and abstractness of the relations which they for- mulate, in the greater definiteness of their: formulas, and in their more complete organization, Our inquiry into the mutual relations of life and intelligence® elicited an exactly p'rallel set of conclusions. It was there shown that psychical life consists in the continuous establishment of subjective rela- tions answering to objective relations ; and that, as we advance through the animal kingdom from the lowest to the highest forms, this correspondence between the mind and the environ- ment extends to relations which are continually more remote in space and time, more clearly defined, but at the same time more general; and finally we also traced a progressive orga- nization of correspondences. Continually; while passing in review. the various aspects of the progress of intelligence in the animal kingdom, we found ourselves: ending with illustrations drawn from that progress of human: intelligence: which is determined by social conditions. Let us now: illus- trate this subject somewhat further by tracing out the. intel- lectual correspondence between man and his environment, as increasing: in remoteness, in speciality and generality, in complexity, in definiteness, and in coherent organization. 1 Spencer’s Essays, 1st series, p. 189; see above, part i. chap. ii.; pars %& chap. xv. ® See.above, part ii, chap. xiv. on. xx] GUNESIS OF MAN, INTELLECTUALLY, 299 The extension of the correspondence in space is a marked characteristic of intellectual progress, which we have already traced through the ascending groups of the animal kingdom, but which is carried much further by man than by any lower animal. It is no doubt true that the direct adjustments of psychical relations to distant objective relations, effected by unaided perception, have a narrower range in civilized men than in uncivilized men or in several of the higher mammals and birds. It is a familiar fact that the senses of civilized man—or at least the three senses which have a considerable range in space—are less acute and less extensive in range than those of the barbarian. It is said that a Bushman can see as far with the naked eye as a European can see with a field-glass ; arid certain wild and domestic birds and mammals, as the falcon, the vulture, and perhaps the greyhound, have still longer vision. Among the different classes of civilized men, those who, by living on the fruits of brain-work done indoors, are most widely differentiated from primeval men, have as a general rule the shortest vision, And the rapid increase of indoor life, which is one of the marked symptoms of modern civilization, tends not only to make myopia more frequent, but also to diminish the average range of vision in persons who are not myopic. There may very likely have been a similar, though less conspicuous and less carefully observed, decrease in the range of hearing. And the sense of smell, which is so marvellously efficient in the majority of mammals and in many savages, is to us of little use as an aid in effecting correspondences in space. In the case also of those simpler indirect adjustments which would seem, perhaps, to involve the use of the cerebellum chiefly, we have partially lost certain powers possessed by savages and lower animals. There are few things in which civilized men differ among themselves more conspicuously than the recollection of places, the identifica- lion of landmarks, and the ability to reach a distant: point 300 COSMIC PHILOSOPHY. [enim through crooked streets without losing the way. But in these respects the most sagacious of us are but bunglers compared with primitive men or with dogs and foxes. Few things are more striking than the unerring instinct with which the Indian makes his way through utterly trackless forests, seldom stopping to make up his mind, and taking in at a single glance whole groups of signs which to his civilized companion are inappreciable, The loss of this power of co- ordination, like the decrease in the range of the senses, is undoubtedly due to disuse, the circumstances of civilized life affording little or no occasion for the exercise of these faculties, But although in these respects the correspondence in space does not seem to have been extended with the progress of civilization, yet in those far more indirect and complicated adjustments which, as involving time-relations of force and cause, depend largely on the aid of the cerebrum, the civil- ized man surpasses the savage to a much greater extent than the savage surpasses the wolf or lion. “ By combin- ing his own perceptions with the perceptions of others as registered in maps,” the modern “can reach special places lying thousands of miles away over the earth’s surface. A ship, guided by compass and stars and chronometer, brings him from the antipodes information by which his purchases here are adapted to prices there. From the characters of exposed strata he infers the presence of coal below; and thereupon adjusts the sequences of his actions to coexist- ences a thousand feet beneath. Nor is the environment 1 In the course of the recent interesting discussion and correspondence in Nature concerning the “ sense of direction” exhibited in barbarians and lower animals, it was observed that a party of Samoyeds will travel in a direct line fron. yne point to another over trackless fields of ice, even on cloudy nights, when there is accordingly nothing whatever that is visible to guide their course. It would be too much to assert that this faculty is utterly lost in civilizzd man, so that a temporary recurrence to the conditions of barbaric life might not revive it; but even if retained at all, it is certainly kept quite in abeyanc> ou. xx1.] GENESIS OF MAN, INTELLECTUALLY. 301 through which his correspondences reach limited to the sur- face and the substance of the earth. It stretches into the surrounding sphere of infinity.” In all these respects, the extension of the correspondence achieved during the progress of civilization has been much greater than that achieved during the immediately preceding stages of the evolution of man from an inferior primate, “ From early races acquainted only with neighbouring localities, up to modern geographers who specify the latitude end longitude of every place on the globe; from the ancient builders and metallurgists, knowing but surface deposits, up to the geologists of our day whose data in some cases enable them to describe the material existing at a depth never yet reached by the miner; from the savage barely able to say in how many days a full moon will return, up to the astronomer who ascertains the period of revolution of a double star ;—there has been ” an enormous “widening of the surrounding region throughout which the adjustment of inner to outer relations extends.”! It only remains to add that the later and more conspicuous stages of this progress have been determined by that increase in. the size and heterogeneity of the social environment which results from the growing interdependence of communities once isolated, and which we have already seen to be the fundamental element of progress in general. For this inte- gration of communities has not only directly enlarged the area throughout which adjustments are required to be made, but it has indirectly aided the advances in scientific know- ledge requisite for making the adjustments. Great, however, as has been the extension of the corre- spondence in space which has characterized the progress of the favoured portion of humanity from barbarism to civiliza- tion, the extension of the correspondence in time is a much more conspicuous and more distinctly human phenomenon, As we trace this kind of mental evolution through sundry 1 Spencer, Princ‘ples of Psychology, vol. i. pp. 317, 319, 308 COSMIC PHILOSOPHY. [pr. classes and orders of the animal kingdom in an ascending series, it is to be observed that until we reach the higher mammals the two kinds of correspondence advance together, —the distance at which outer relations are cognized forming a measure of the interval by which their effects may be anticipated. But among the higher mammals there is observed a higher order of adjustments to future emer- gencies, which advances more rapidly than the extension of the correspondence in space, and which in the human race | first acquires a notable development. ‘“ Not that the transi- tion is sudden,” observes Mr. Spencer. “ During the first stages of human progress, the method of estimating epochs does not differ in nature from that employed by the more intelligent animals. There are historical traces of the fact that originally the civilized races adjusted their actions to the lonver sequences in the environment just as Aus- tralians and Bushmen do now, by observing their coincidence with the migrations of birds, the floodings of rivers, the flowerings of plants. And it is obvious that the savages who, after the ripening of a certain berry, travel to the sea- shore, knowing that they will then find a particular shell-fish in se.son, are guided by much the same process as the dog who, on seeing the cloth laid for dinner, goes to the window to watch for his master, But when these phenomena of the seasons are observed to coincide with recurring phenomena in the heavens,—when, as was the case with the aboriginal THlottentots, periods come to be measured partly by astro- nomical and partly by terrestrial changes,—then we see making its appearance a means whereby the correspondence in time may be indefinitely extended. The sun’s daily movements and the monthly phases of the moon having once been generalized, and some small power of counting having been reached, it becomes possible to recognize the interval between antecedents and consequents that are long apart, and to adjust the actions to them.

In the advance to high stages of civilization, the extension of the correspondence in time is most conspicuously exempli- fie] in the habitual adjustment of our theories and actions to sequences more or le3s »emote in the future. In no other respect is civilized man more strikingly distinguished from the barbarian than in his power to adapt his conduct te future events, whether contingent or certain to occur. The ability to forego present enjoyment in order to avoid the risk of future disaster is what we call prudence or providence ; and the barbarian is above all things imprudent and impro- vident. Doubtless the superior prudence of the civilized man is due in great part to his superior power of self restraint ; so that this class of phenomena may be regarded as illustrating one of the phases of moral progress. Never- theless there are several purely intellectual elements which enter as important factors into the case. The power of economizing in harvest-time or in youth, in order to retain something upon which to live comfortably in winter or in old age, is obviously dependent upon the vividness with which distant sets of circumstances can be pictured in the imagination. The direction of the volitions involved in the power of self-restraint must be to a great extent deter- mined by the comparative vividness with which the distant circumstances and the present circumstances are mentally realized. And the power of distinctly imagining objective relations not present to sense is probably the most fundamen- tal of the many intellectual differences between the civilized man and the barbarian, since it underlies both the class of phenomena which we are now considering. and the class of phenomena comprised in artistic, scientitic, and philosophic 1 Spencer, op. cit. i. 326, 304: COSMIC PHILOSOPHY. [pr. 1 progress. The savage, with his small and undeveloped cere- brum, plays all summer, like the grasshopper in the fable, eat- ing and wasting whatever he can get; for although he knows that the dreaded winter is coming, during which he must starve and shiver, he is nevertheless unable to realize these distant feelings with sufficient force to determine his volition in the presence of his actual feeling of repugnance to toil. But. the civilized man, with his large and complex cerebrum, has so keen a sense of remote contingencies that he willingly submits to long years of drudgery, in order to avoid poverty in old age, pays out each year a portion of his hard-earned money to provide for losses by fire which may never occur, builds houses and accumulates fortunes for posterity to enjoy,. and now and then enacts laws to forestall possible disturb- ances or usurpations a century hence. ‘Again, the progress of scientific knowledge, familiarizing civilized man with the idea of an inexorable regularity of sequence among events, greatly assists him in the adjustment of his actions to far- distant emergencies. He who ascribes certain kinds of suffer- ing to antecedent neglect of natural laws is more likely to, shape his conduct so as to avoid a recurrence of the infliction, than he who attributes the same kinds of suffering to the wrath of an offended quasi-human Deity, and fondly hopes,, by ceremonial propitiation of the Deity, to escape in future. - This power of shaping actions so as to meet future contin- gencies has been justly recognized by political economists as au indispensable pre-requisite to the accumulation of wealth in any community, without which no considerable degree of progress can be attained. The impossibility of getting barbarians to work, save under the stimulus of actually present necessities, has been one of the chief obstacles in the way of missionaries who have attempted to civilize tribal] eommunities. The Jesuits; in the seventeenth century, were the most successful of Christian missionaries, and their pro- seedings with the Indians of Paraguay constitute one of the on, xx1.] GENESIS OF MAN, INTELLECTUALLY. 305. most brilliant feats in missionary annals. Such unparalleled ascendency did the priests acquire over the imaginations of these barbarians that they actually made them cease from warfare. They taught them European methods of agriculture, as well as the arts of house-building, painting, dyeing, furniture-making, even the use of watches ; and they administered the affairs of the community with a despotic. power which has seldom been equalled either in absoluteness or in beneficence. Nevertheless the superficiality of all this show of civilization was illustrated by the fact that, unless perpetually watched, the workmen would go home leaving their oxen yoked to the plough, or would even cut them up for supper if no other meat happened to be at hand. Examples of a state of things intermediate between this barbaric improvidence and the care-taking foresight of the European are to be found among the Chinese,—a people who have risen far above barbarism, but whose civilization is still of a primitive type, The illustration is rendered peculiarly forcible by the fact that the Chinese are a very industrious people, and where the returns for labour are imm.diate will work as steadily as Germans or Americans. Owing to their crowded population, every rood of ground is’ needed for cultivation, and upon their great rivers the traveller continually meets with little floating farms con- structed upon rafts and held in place by anchors. Yet side by side with tliese elaborate but tragile structures are to be seen acres of swamp-land which only need a few years: of careful draining to become permanently fit for tillage. So incapable are the Chinese of adapting their actions to sequences at all remote, that they continue, age after age, to resort to such temporary devices, rather than to bestow their labour where its fruits, however enduring, cannot be enjoyed from the outset! The contrast proves that the cause is the intellectual inability to realize vividly a group of : 1 See Mill, Political Eionumy, book i. chap xi, VOL. II. x 306 COSMIC PHILOSOPHY, (rr. 1. future conditions, involving benefits not immediately to be felt. Of the correspondence in time, even more forcibly than of the correspondence in space, it may be said that its extension during the process of social evolution has been much greater than during the organic evolution of the human race from some ancestral primate. Between the Australian, on the one hand, who cannot estimate the length of a month, or provide even for certain disaster which does not stare him in the face, and whose theory of things is adapted only to events which occur during his own lifetime; and, on the other hand, the European, with his practical foresight, his elaborate scientific previsions, and his systems of philosophy, which embrace alike the earliest traceable cosmical changes and the latest results of civilization; the intellectual gulf is certainly far wider than that which divides the Australian from the fox who hides the bird which he has killed, in order to return when hungry to eat it. It remains to add that the later and more conspicuous stages of this kind of intellectual progress have obviously been determined by the increase in the size and heterogeneity of the social environment. For the integration of commu- nities to which this increase is due has not only indirectly aided the advances in scientific knowledge requisite for making mental adjustments to long sequences, past and future, but it has also directly assisted the disposition to work patiently in anticipation of future returns, by increas- ing the general security and diminishing the chances that the returns to labour may be lost. The extension of the correspondence between subjective and objective relations in time and in space answers to that kind of primary integration which underlies the process of — evolution in general. In treating of the enlarged area, in time and space, throughout which inner relations are adjusted to outer relations, we have been treating of intellectual pro- cn. xxi] GENESIS OF MAN, INTELLECTUALLY. 307 gress regarded as a growth. But in proceeding to speak of the increasing heterogeneity, definiteness, and coherence of the adjustments, we proceed to treat of intellectual progress regarded as a development. Here, as elsewhere, throughout all save the simplest orders of evolution, quantitative increase is accompanied by qualitative increase. The knowledge is not only greater and the intellectual capacity greater, but the knowledge is more complex, accurate, and unified, and the intellectual capacity is more varied, The increase of the correspondence in definiteness may be sufficiently illustrated by the following brief citation from Mr, Spencer: “ Manifestly the reduction of objective pheno- mena to definite measures gives to those subjective actions that correspond with them a degree of precision, a special fitness, greatly beyond that possessed by ordinary actions, There is an immense contrast in this respect between the doings of the astronomer wlio, on a certain day, hour, and minute, adjusts his instrument to watch an eclipse, and those of the farmer who so arranges his work that he may have hands enough for reaping some time in August or September. The chemist who calculates how many pounds of quicklime will be required to decompose and precipitate all the bicar- bonate of lime which the water in a given reservoir contains in @ vertain percentage, exhibits an adjustment of inner to outer relations incomparably more specific than does the Jaundress who softens a tubful of hard water by a handful of soda. In their adaptations to external coexistences and sequences, there is a wide difference between the proceedings of ancient besiegers, whose battering-rams were indeterminate in their actions, and those of modern artillery officers, who, by means of a specific quantity of powder, consisting of specific ingredients, in specific proportions, placed in a tube at a specific inclination, send a bomb of specific weight on to & specific object, and cause it te explode at a specific x 2 308 - QOSMIC PHILOSOPHY. fpr. moment.” It only remains to note that the difference in specific accuracy, here illustrated by contrasting the opera- tions of science with those of ordinary knowledge, is equally conspicuous when, on a somewhat wider scale, we contrast the proceedings, both scientific and artistic, of civilized men with the proceedings of the lowest savages. The most ignorant man in New England probably knows in June that winter is just six months distant; the Australian, to whon, as to the civilized child, time appears to go slowly, knows only that it is a long way off. So, too, the crude knives and hammers and the uncouth pottery of primeval men are distinguisied alike by their indefiniteness of contour, and by their uselessness in operations which require specific accuracy. And here, as before, in the extreme vagueness and lack of speciality, both in his knowledge and in the actions which are guided by it, the primeval man appears to stand nearer to the highest brutes than to the civilized moderns. Along with this increase in specialization, entailing greater definiteness of adjustment, there goes on an in- crease in generalization, involving an increased power of abstraction, of which barely the germs are to be found either in the lowest men or in other highly organized mammals. The inability of savage races to make generalizations in- volving any abstraction is sufficiently proved by the absence or extreme paucity of abstract expressions in their languages.’ As Mr. Farrar observes, “The Society-Islanders have words for dog’s tail, bird’s tail, and sheep’s tail, yet no word for tail; the Mohicans have verbs for every kind of cutting, and yet no verb ‘to cut.’ The Australians have no generic term for fish, bird, or tree. The Malavs have no term for tree or herb, yet they have words for fibre, root, tree-crown, stalk. stock, trunk, twig, and shoot. Some American tongues have separate verbs for ‘I wish to eat meat,’ and ‘I wish to eat soup, — Sut no verb for ‘I wish’; and separate words for a blow with 1 Spencer, op. cit. i, 340. cH. xx1.] GENESIS OF MAN, INTELLECTUALLY. 809 a sharp and a blow with a blunt instrument, but no abstract word for blow.”! Between the stage of intellectual progress thus illustrated and that in which an unlimited capacity for generalization pzoduces such words as “individuation” or “equilibration,” the contrast is sufficiently obvious; and it fully confirms our theorem, that the amount of intellectual progress achieved since man became human far exceeds that which was needed to transfer him from apehood to manhood. The increase of the correspondence in complexity, already illustrated incidentally in the treatment of these other aspects of the case, is still further exemplified in the growing complication of the interdependence between science and the arts. When tracing the complexity of correspondence through the lower stages of the evolution of intelligence in the animal kingdom, Mr. Spencer hints that the evolution of the executive faculties displayed in the organs of prehension and locomotion is closely related to that of the directive faculties displayed in the cenhalic ganglia and in the organs of sense. The parallelism may be summed up in the state- ment that in most, if not all, the principal classes of the animal kingdom, the animals with the most perfect prehensile organs are the most intelligent. Thus the cuttle-fish is the most intelligent of mollusks, and the crab similarly stands at the head of crustaceans, while the parrot outranks all other birds alike in sagacity and in power of handling things, and ° the ape and elephant are, with the exception of man, the most sagacious of mammals.! Of the human race, too; it may be said that, although Anaxagoras was wrong in assert- ing that brutes would have been men had they had hands, he might safely have asserted that without hands men could never have become human. Now this interdependence of the directive and executive faculties is continued throughout the process of social evolution in the shape of the inter- 2 Chapters on Language, p. 199. * Spencer, op, sit. i, 368—372, 310 COSMIC PHILOSOPHY. (er. 1, dependence of the sciences and the arts. “We may properly say that, in its higher forms, the correspondence between the organisni and its environment is effected by means of supple- mentary senses and supplementary limbs, . . . . The magni- fying-glass adds but another lens to the lenses existing in the eye. The crow-bar is but one more lever attached to the series of levers forming the arm and hand. And the rela-. tionship, which is so obvious in these first steps, holds throughout.” We may, indeed, go still deeper, and say that science is but an extension of our ordinary sense-perceptions by the aid of reasoning, while art is but an extension of the ordinary function of our muscular system, of expressing our psychical states by means of motion. Hence it is that “each great step towards a knowledge of laws has facilitated men’s operations on things; while each more successful operation on things has, by its results, facilitated the discovery of further laws.” Hence the sciences and arts, originating together,—as in the cases of “astronomy and agriculture, geometry and the laying out of buildings, mechanics and the weighing of commodities,’—have all along reacted upon each other, in an increasing variety of ways. It is sufficient to mention the reciprocal connections between navigation and astronomy, between geology and mining, between chemistry and all the arts; while telescopes and microscopes illustrate *the truth that “there is scarcely an observation now made in science, but what involves the use of instruments supplied »y the arts; while there is scarcely an art-process but what involves some of the previsions of science.” Just as in organic evolution we find the mutual dependence of the directive and executive faculties ever increasing, so that “complete visual and tactual perceptions are impossible without complex muscular adjustments, while elaburate actions require the constant overseeing of the senses”; so in 3ocial evolution we find-between science and art an increas- ing reciprocity “such that. cach further cognition implies cu. xx1.] GENESIS OF MAN, INTELLECTUALLY. Sil elaborate operative aid, and each new operation implies sundry elaborate cognitions.” I need only add that, in this as in the other aspects of intellectual progress, the increase in complexity of adjustment achieved during the process of social evolution is far greater than that achieved during the immediately preceding stages of the process of organic evolution. Between the ape and the primitive man, with his rude levers and hatchets and his few simple previsicns, the difference in complexity of correspondence is obviously less than between the primitive man and the modern, with his steam-hammers and thermo-electric multipliers, and his long list of sciences and sub-sciences, any one of which it would take much more than a lifetime to master in detail. We have thus passed in review the various aspects of intellectual progress, regarded as a process of adjustment of inner to outer relations, and we have seen that in all the most. essential features of this progress there is a wider dif- ference between the civilized man and the lowest savage than between the savage and the ape. It appears that those rare and admirable qualities upon which we felicitate ourselves as marks whieh absolutely distinguish us from brute an‘mals.. have been slowly acquired through long ages of social evolu- tion, and are shared only to a quite insignificant extent by the lowest contemporary races of humanity. As long as we regard things statically, as for ever fixed; we may well imagine an impassable gulf between ourselves and all other forms of organic existence. But as soon as we regard things dynamically, as for ever changing, we are taught that the eulf has been for the most part established during an epoch at the very beginning of which we were zoologically the same that. we now are. The next step in our argument will be facilitated by an inquiry into the common characteristic of the various intel- lectual differences between the civilized and the primitive man which we have above enumerated. The nature of this 312 COSMIC PHILOSOPHY. fer. 1. characteristic was hinted at when we were discussing the improvidence of the. barbarian. It was observed that the power of distinctly imagining objective relations not present to sense is the most fundamental of the many intellectual differences between the civilized man and the barbarian. Making this statement somewhat wider, we may now safely assert that the entire intellectual superiority of the civilized man over the savage, or of the modern man over the primeval man, is summed up in his superior power of representing that — which is not present to the senses. For it is not only in what we call providence that this superiority of representation shows itself, but also in all those combinations of present with past impressions which accompany the extension of the correspondence in space and time, and its increase in hetero- geneity, definiteness, and coherence, It is his ability to re- produce copies of his own vanished states of consciousness, and of those of his fellows, that enables the civilized men to adjust his actions to sequences occurring at the antipodes. It is this same power of representation which underlies his power of forming abstract and general conceptions. For the peculiarity of abstract conceptions is that “the matter of thought is no longer any one object, or any one action, but a trait common to many”; and it is, therefore, only when a number of distinct objects or relations possessing some common trait can be represented in consciousness that there becomes possible that comparison which results in the ab- straction of the common -trait as the object of thought. Obviously, then, the greater the power of abstraction and generalization which is observed, the greater is the power of representation which is implied. The case is the same with that definiteness of the intellectual processes which we have noted as distinguishing modern from: primitive thinking. For. the conception which underlies definiteness of thinking is the conception of exact likeness,—a highly abstract concep- tion which can only be framed after the comnarison of om. xxt.] GHNESIS, OF MAN, INTELLECTUALLY. 213 numerous represented eases in which degree of likeness is the common trait that is thought about. Hence not only the improvidence of the savage, but likewise the vagueness of his conceptions, his inability to form generalizations in- volving abstraction, and the limited area covered by his adjustments, are facts which one and all find their ultimate explanation in his relative incapacity for Goalie up repre- sentative states of consciousness. From this same incapacity results that inflexibility of thought in which the savage resembles the brute, and which is one of the chief proximate causes of his unprogressive- ness. “One of the greatest pains to human nature,” says Mr, Bagehot, “is the pain of a new idea.” This pain, which only to a few of the most highly cultivated minds in the most highly civilized communities has ceased to be a pain and become a pleasure, is to the savage not so much a pain as a numbing or paralyzing shock. To rearrange the elements of his beliefs is for the uncivilized man an almost impossible task. It is not so much that he does not dare to sever some traditional association of ideas which he was taught in child- hood, as it is that he is incapable of holding together in thought the clusters of representations with the continuity of which the given association is incompatible. This im- portant point is so ably and succinctly stated by Mr. Spencer, that I cannot do better than to quote his exposition entire. After reminding us that “ mental evolution, both: intellectual and emotional, may be measured by the degree of -remote- hess from primitive reflex action,” Mr. Spencer observes that “in reflox avtion, which is the action of nervous structures that effect few, simple, and often-repeated coordinations, the sequent nervous state follows irresistibly the antecedent nervous state; and does this not only for the reason that the discharge follows a perfectly permeable channel, bzt also for the reason that no alternative channel exists. From this stayo, in which the psychical life is automatically restrained 314 COSMIC PHILOSOPHY, ter. nm. within the narrowest limits, up through higher stages in which increasing nervous complexities give increasing varie- ties of actions and possibilities of new combinations, the process continues the same; and it continues the same as we advance from the savage to the civilized man. For where the life furnisies relatively few and little-varied experiences, where the restricted sphere in which it is passed yields no sign of the multitudinous combinations of phenomena that occur elsewhere, the thought follows irresistibly one or other _ oi the few channels which the experiences have made for it, —cannot be determined in some other direction for want of some other channel. But as fast as advancing civilization brings more numerous experiences to each man, as well as accumulations of other men’s experiences, past and present, the ever-multiplying connections of ideas that result imply ever-multiplying possibilities of thought. The convictions throughout a wide range of cases are rendered less fixed. Other causes than those which are usual become conceivable 3 other effects can be imagined ; and hence there comes an in- creasing modifiability of opinion. This modifiability of opinion reaches its extreme in those most highly cultured persons whose multitudinous experiences include many experiences of errors discovered, and whose representativeness of thought is so far-reaching that they habitually call to mind the various possibilities of error, as constituting a general reason for seeking new evidence and subjecting their conclusions to revision. “If we glance over the series of contrasted modes of thinking which civilization presents, beginning with the savage who, seized by the fancy that something is a charm or an omen, thereafter continues firmly fixed in that belief, and ending with the man of science whose convictions, firm where he is conscious of long-accumulated evidence having no exception, are plastic where the evidence though abun. dant is not yet overwhelming, we see how an increase in cu, xx1.] GENESIS OF MAN, INTELLECTUALLY, 315 freedoin of thought goes along with that higher representa- tiveness accompanying further mental evolution.”?* is now we inquire for a moment into the causes of this higher representativeness of civilized thinking, we shall see most beautifully exemplified the way in which intellectual progress, as it goes on in the human race, is ‘etermined by social evolution. Intellectual progress is indeed a cause as well as a consequence of the evolution of society ; but amid the dense entanglement of causes and effects our present purpose requires us to single out especially the dependence of progress in representativeness upon social complexity, since herein will be found the secret of the mental pre- eminence of civilized man, Now the integration of small tribes into larger and more complex social aggregates, which is the fundamental phenomenon in civilization, tends directly to heighten representativeness of thinking by widening and varying the experiences of the members of society. The member of a savage tribe must think indefinitely, concretely, rigidly, improvidently, because his intellectual experiences are so few in number and so monotonous in character. In- crease in social complexity renders possible, or indeed directly produces, fresh associations of ideas in greater and greater variety and abundance, so that the decomposition and re- combination of thoughts involved in abstraction and genera- lization is facilitated; and along with this, the definiteness and the plasticity of thought is increased, and the contents of the mind become representative in higher and higher degrees. Thus in every way it is brought before us that sociality has been the great agent in the achievement of man’s intellectual pre-eminence, and that it has operated by widening and diversifying human experience, or in other words by increasing the number, remoteness, and hetero- gencity of the environing relations to which each individual’s actions have had to be adjusted, Am inquiry into the 2 Spencer, op. cit. ii. 524, 316 ---. @OSMIC PHILOSOPHY. fpr. m, genesis of. sociality will therefore best show us how the chasm which divides man intellectually from the brute is to be: crossed. . But bifors we proceed to this somewhat binighee and cir: cuitous inquiry, we may profitably contemplate under a new aspect the intellectual difference which we have assigned as the fundamental one between civilized and primeval man. We have observed that the intellectual superiority of man over brute and of the civilized man over the barbarian essen- tially consists in a greater capacity for mentally representing objects and relations remote from sense. And we have insisted upon the point that in this capacity of representation the difference between the highest and lowest specimens of normal humanity known to us far exceeds the difference between the lowest men and the highest apes. Now in closest connection. with these. conclusions stands the physical fact that the chief structural difference between man and ape, as also between civilized and uncivilized man, is the difference in size and complexity of cerebrum, The cerebrum is the organ especially set apart for the compounding and re- ‘compounding of impressions that are not immediately sensory, The business of coordinating immediately presentative im-_ pressions is performed by the medulla and other subordinate centres.. The cerebrum is especially the organ-of that portion .of psychical life which is entirely representative. Obviously, then, the progress to higher and higher representativeness ought to be aoouinipauiad by a well-marked growth of the cerebrum relatively to the other parts of the nervous system, ‘Now, in the light of the present arcument, how ‘significant ‘is the fact ‘that the. cranial capacity ‘of the modern English- man surpasses that of the. aboriginal pp etyan Hindu by a difference of sixty-eight cubic. inches,” while between this Hindu skull and the’ skull of the porills the differenep 1 See above, p. 137.5 | | ae Ot * Lyell, Antiquity of Mam, p. a4 gu. xxi.) GENESIS-OF MAN, INTELLECTUALLY. 317 in capacity is but eleven cubic inches! That is to say, the difference in volume of brain between the highest and the lowest man is at least six times as great as the difference between the lowest man and the highest ape. And if we were to take into the account the differences in structural complexity, as indicated by the creasing and f-rowing of the brain-surface, we should obtain ‘a yet:more astonishing contrast. Yct, powerfully as this anatomical fact confirms the position we have all along been upholding, its full value will not be apparent if we are so dazzled by it as to overlook the significance of the lesser difference between the gorilla and the aboriginal inhabitant of India.: As the Duke of Argyll very properly observes, we do right-in setting a higher value in classification upon the eleven inches which intervene between the gorilla and the Hindu than upon the sixty-eight inches which intervene between the Hindu and the English- man.. For “the sienificance set by the facts of nature upon that difference of eleven cubic inches ... .-is the difference between an irrational brute confined to ’some one climate and. to some hmited area of the globe,—which no outward conditions can modify or improve,—and a being equally adapted to the whole habitable world, with powers, however undeveloped, of comparison, of reflection; of judgment, of reason; with a sens¢ of right and ‘wrong, and with all these: capable of accumu- lated acquisition, and therefore of: indefinite. advance.” Though somewhat exaggerated in what it: denies to the brute, and much more in what it claims for the aboriginal man, this statement contains.a. kernel of truth which is of value for our present purpose, and which is further illustrated by the fact that a minimum of brain-substance “‘is constantly and uniformly associated with all the other anatomical peculiarities of man. Below that minimum the whole accompanying structure undergoes far more than a corre sponding change,—even the whole change between the lowest pavage and the highest ape. Above that minimum, all 318 COSMIC PHILOSOPHY. [rr. 1, subsequent variations in quantity are accompanied by na changes whatever in physical structure.”+ Here again, though the antithesis is a little too absolutely stated, we have set before us a real distinction. Up to a certain point, the brain and the rest of the body are alike alterable by natural selection’ and such other agencies as may be concerned in the slow modification of organisms. But when the brain has reached a certain point in size and complexity, the rest of the body ceases to change, save in a few slight particulars, and the agencies concerned in forwarding the process of evolution seein to confine themselves to the brain, and especially to the cerebrum,—the result being marked psychical development, unattended by any notable physical alteration. Here we have reached a fact of prime importance. We may grant to the Duke of Argyll that when those eleven additional cubic inches of brain had been acquired, some kind of a Rubicon had been crossed, and a new state of things inaugurated. What was that Rubicon ? _ The answer has been furnished by Mr. Wallace, and must rank as one of the most brilliant contributions ever yet made to the Doctrine of Evolution. Since inferior animals respond chiefly by physical changes to changes in their environment, natural selection deals chiefly with such changes, to the visible modification of their bodily structure. In the case of sheep or bears, for instance, increased cold can only select for preservation the individuals most warmly coated ; or if a race of lions, which has hitherto subsisted upon small and sluggish tuminants until these have been nearly exterminated, is at last obliged to attack antelopes and buffaloes, natural selection can only preserve the swiftest and strongest or most ferocious lions. But when an animal has once appeared, endowed with sufficient intelligence to chip a stone tool and hurl a weapon, natural selection will take advantage of variations in this intelligence, to the comparative neglect of purely piyded 2 Duke of Argyll, Primeval Man, pp. 57—64. cH. xx1.]) GENESIS OF MAN, INTALLECTUALLY, 319 variations. Communities whose members are best able to meet by intelligent contrivances the changes in the environ- ment wili prevail over other communities, and will also be less easily destroyed by physical catastrophes. Still more strikingly must this superior availability o. variations in intelligence be exemplified, when the intelligence has pro- gressed so far as to sharpen spears, to use rude bows, to dig pitfalls, to cover the body with leaves or skins, and to strike fire by rubbing sticks, according te the Indian version of the myth of Prometheus, So soon, in short, as the intelligence of an animal has, through ages of natural selection and direct adaptation, be- come so considerable that a slight variation in it is of more use to the animal than any variation in physical structure, then such variations will be more and more constantly selected, while purely physical variations, being of less vital importance to the species, will be relatively more and more neglected, Thus, while the external appearance of such an animal, and the structure of his internal nutritive and mus- cular apparatus, may vary but little in many ages, his cere- bral structure will vary with comparative rapidity, entailing a more or less rapid variation in intellectual and emotional attributes, Here we would seem to have the key to the singular con- trast in the relations of man to contemporary anthropoid apes. We may now understand why man differs so little, in general physical structure and external appearance, from ‘the chimpanzee and gorilla, while, with regard to the special point of cerebral structure and its correlative intel- ligence, he differs so vastly from these, his nearest living congeners, and the most sagacious of animals save himself. Coupled with what we now know concerning the inimense intiquity of the human race, Mr. Wallace’s brilliant sugges- tion goes far to bridge over the interval, which formerly seemed so impracticable, between brute and man. If we 321) COSMIC PHILOSOPHY. [pr take the thousands of centuries during which the human race has covered both the eastern and the western hemispheres, and compare with them the entire duration of recorded human history, we shall have set before us a profitable subject of reflection. Since the period during which man has pos- sessed sufficient intelligence to leave a traditionary record of himself is but an infinitesimal fraction of the period during which he has existed upon the earth, tt is but fair to conclude that, during those long ages of which none but a geologic record of his existence remains, he was slowly ACQUIRING that superior. intelligence which now so widely distingwishes him from all other animals:' Throughout an enormous period of time, his: brain-structure and its correlated intellectual and emotional: functions must have been constantly modified both by natural selection and by direct adaptation, while his outward physical’ appearance has undergone few modifications ; and of these. the most striking would. seem to be directly or indirectly: consequent: upon the cerebral changes,” | 1 The reader will not fail to note that, even were the question otherwise: left open, after the conclusive evidence summarized in chapter ix., this point, by itself is ‘a point of truly enormous weight in favour of the theory of man’s descent from some lower animal. Upon the theory that the human race was created by a special miraculous act, its long duration in such utter silence is a meaningless, inexplicable fact ; whereas, upon the derivation theory, it is just what might be expected. ; 2 To the general observer, as to the anatomist, the most notable points of difference between civilized and uncivilized’ man, as well as between man and the chimpanzee or gorilla, are the differences in the size of the jaws and the inclination of the forehead. The latter difference is directly consequent upon increase of intelligence ; and the former is indirectly occasioned by the same circumstance. For the diminution of the jaws, entailed by civilization, is, no doubt, primarily due to disuse ; and the disuse is occasioned partly by dif- ference in food, and partly by the employment of tools, and the consequent increased reliance upon the hands as prehensile organs. All these circum- stances are the result of increased intelligence. And in addition to this, it is probable that increased frontal developient has directly tended, by correla- tion of growth, to diminish the size of the jaws, as well as to push forwaid the bridge of the nose. To the increased’ reliance upon the hands as prehen- sile orgaus—a circumstance which we have seen’ to be in/an especial degree characteristic of developing intelligence—is probably also due the. complete attainment of the erect position of the body, already partially obtained hy the anthropoid: apes. . Cerebral development thus accounts for all the con: spicuous physical peculiarities of man except his bare skin, —a phenomenog for which no sutisiactory explanation has yet been suggested. ee ST ex. xx1.] GENESIS.OF MAN, INTELLECTUALLY. . 221. It is a corollary from the foregoing considerations, that no race of organisms can in fature tie produced through the. agency of sata) selection and direct adaptation, which shall, be zoologically distinct from, and superior to, the human race.: As the same causes which physically modify lower species; have, for countless ages, modified man directly and greatly in: intelligence and only indirectly and slightly in physical con- stitution, it follows that mankind is destined to advance, during future ages in psychical attributes, but is likely to. undergo only slight changes in. outward appearance. It is: by the coordination of intellectual and moral relations that. man maintains himself in equilibrium with the physical, in-, tellectual, and moral relations arising in his ever-changing. environment. And hence in thefuture, as in the recent, past, the dominant. fact in the career of humanity is not “7 sical; modification, but CIVILIZATION. "| ‘y - Here we are brought by a new route to the verge of that theory of civilization which I have sought to elucidate:i in the preceding chapters. We have touched upon a grand truth, of which it would be difficult to overrate the importance.’ For we can now admit—not as a concession to Mr. St. George. Mivart, but as a legitimate result of our own method of. inquiry—that when “the totality of man’s being” is taken! into the account, the difference between ape and mushroom: is less important than the difference between ape and man. And without conceding aught to that superlative nonsense known as the “doctrine of special creations,” we may admit, with the Duke of Argyll, that the eleven cubic inches of. brain-space, by which the aboriginal Hindu surpasses the gorilla, have a higher value, for purposes of classification,’ than the sixty-eight cubic inches by which the modern: Englishman surpasses the Hindu. We now see what kind: of a Rubicon it was’ which was crossed when those eleven. cubic inches of brain (or even when four or five of them), had been gained. The crossing of the Rubicon was the: VOL, IL. Df 322 COSMIC PHILUSUPHY., [pr. 11. point at which natural selection began to confine itscif chiefly to variations in psychical manifestation. The ape-like pro- genitor of man, in whom physical and psychical changes had gone on part passu for countless scons, until he had reached the grade of intelligence implied by the possession of a brain four or five inches more capacious than that of the gorilla had now, as we may suppose, obtained a brain upon which could be devolved, to a greater and greater extent, the task of maintaining relations with the environment. Then began a new chapter in the history of the evolution of life. Hence- forward the survival of the fittest, in man’s immediate an- cestry, was the survival of the cerebrums best able to form representative combinations. The agencies which had hitherto been at work in producing an organic form endowed with rare physical capacities, now began steadfastly to labour in pro- ducing a mind capable to‘a greater and greater extent of ideally resuscitating and combining relations not present to the senses. But immense as was the step thus achieved in advance, the progress from brute to man was not yet accomplished. As we have already shown, the circumstances which by widen- ing and diversifying experience have mainly contributed to heighten man’s faculty of representativeness, have been for the most part circumstances attendant upon man’s sociality, or the capacity of individuals for aggregating into communities of increasing extent and complexity. Here we become involved in considerations relating to the emotions as well as to the intelligence. The capacity for sustaining the various relationships implied by the existence of a social aggregate— whether in the case of a primeval family community or of a modern nation—cannot be explained without taking into the account the genesis of those moral feelings by the pusses- sion of which man has come to differ from the highest brutes even more co.spicuously than by his purely intellectual achievements. The task. now before us, therefore, is te cH. xx1.] GENESIS OF MAN, INTELLECTUALLY. 323 explain the genesis of the moral feelings which lie at the bottom of sociality in the human race; and with reference to this question I shall presently have a suggestion to offer, which will be found as serviceable as it is interesting and novel. Let us for the moment, however, consider the impli- cations of some of the current ethical theories, and especially let us examine the scientific basis of what is too crudely designated as Utilitarianism. CHAPTER XXIL GENESIS OF MAN, MORALLY, THERE are two things, said Kant, which fill me with awe because of their sublimity,—the starry heavens above us, and the moral law within us. From the modern point of view there is interest as well as instruction to be found in the implied antithesis. While in the study of the stellar universe we contemplate the process of evolution on a scale so vast that reason and imagination are alike baffled in the effort to trace out its real significance, and we are over- powered by the sense of the infinity that surrounds us; on the other hand, in the study of the moral sense we contem- plate the last and noblest product of evolution which we can ever know,—the attribute latest to be unfolded in the development of psychical life, and by the possession of which we have indeed become as gods, knowing the good and the 2vil. The theorems of astronomy and the theorems of ethics present to us the process of evolution in its extremes of extension and of intension respectively. For although upon other worlds far out in space there may be modes of exist- ence immeasurably transcending Humanity, yet these must remain unknowable by us. And while this possibility should be allowed its due weight in restraining us from the vain endeavour to formulate the infinite and eternal Sustaiuer ee. cH, Xxt11.] GENESIS OF MAN, MORALLY. 825 of the univérse’in terms of our own human nature, as if the highest symbols intelligible to us were in reality the highest symbols, nevertheless it can in no way influence or modify our science. To us the deve’opment of the noblest of human attributes must ever remain the last term in the stupendous series of cosmic changes, of which the development of plane- tary systems is the first term. And our special synthesis of the phenomena of cosmic evolution, which began by seek- ing to explain the genesis of the earth and its companion worlds, will be fitly concluded when we have offered a theory of the genesis of those psychical activities whose end_is to secure to mankind the most perfect fulness of life upon this earth, which is its dwelling-place. The great philosopher whose remark has suggested these reflections would not, however, have been teady to assent to the interpretation here given. Though Kant was one of the chief pioneers of the Doctrine of Evolation, having been the first to propose and to elaborate in detail the theory of the nebular origin of planetary systems, yet the conception of a continuous development of life in all its modes, physical and psychical, was not sufficiently advanced, in Kant’s day, to be adopted into philosophy. Hence in his treatment of the mind, as regards both intelligence and emotion, Kant took what may be called a statical view of the subject; and finding in the adult civilized mind, upon the study of which his systems of psychology and ethics were founded, a number of organized moral intuitions and an organized moral sense, which urges men to seek the right and shun the wrong, irrespective of utilitarian considerations of pleasure and pain, he proceeded to deal with these moral intuitions and this moral sense as if they were ultimate facts, incapable of being analyzed into simpler emotional elements, Now as the following exposition may look like a defence of utili- farianism, it being really my intention to show that utili-’ \arianism in the deepest and. widest sense-is the ethical 326 COSMIC PHILOSOPHY. frrom philosophy imperatively required by the facts, it is well to state, at the outset, that the existence of a moral sense and moral intuitions in civilized man is fully granted. It is admitted that civilized man possesses a complex group of emotions, leading him to seek the right and avoid the wrong, without any reference to considerations of utility ; and I disagree entirely with those utilitarian disciples of Locke, who would apparently refer these ethical emotions to the organization of experiences of pleasure and pain in the case of each individual. So long as the subject is contemplated from a statical point of view, so long as individual experience is studied without reference to, an- cestral experience, the follower of Kant can always hold his ground against the follower of Locke, in ethics as well as in psychology. When the Kantian asserts that’ the in- tuitions of right and wrong, as well as the intuitions of time and space, are independent of experience, he occupies a position which is impregnable, so long as the organization of experiences through successive generations is left out of the discussion. But already, on two occasions of supreme importance, we have found the Doctrine of Evolution lead- ing us to a common ground upon which the disciples of Kant and the disciples of Locke can dwell in peace together. We have seen that the experience-test and the incon- ceivability-test of truth are, when deeply considered, but the obverse faces of the same thing. We have seen that there is a stand-point from which the experience-theory and the intuition-theory of knowledge may be regarded as mutually supplementing each other. We shall presently see, in like manner, that the so-called doctrine of utili- tarianism and the doctrine of moral intuitions are by no means so incompatible with one another as may at first appear. As soon as we begin to study the subject dynami- cally, everything is shown in a new light. Admitting the truth of the Kantian position, that there exists in us a eH. XXI1.] GENESIS OF MAN, MORALLY. 327 moral sense for analyzing which our individual experience does not afford the requisite data, and which must there- fore be regarded as ultimate for each individual, it is never- theless open to us to inquire into the emotional antecedents of this organized moral sense as exhibited in ancestral types of psychical life. The inquiry will result in the conviction that the moral sense is not ultimate, but derivative, and that it has been built up out of slowly organized experiences of pleasures and pains. | But before we can proceed directly upon the course thus marked out, it is necessary that we should determine what are meant by pleasures and pains. What are the common characteristics, on the one hand; of the states of conscious- ness which we call pleasures, and, on the other hand, of the states of consciousness which we call pains? According to Sir William Hamilton, “ pleasure is a reflex of the sponta- neous and unimpeded exertion of a power of whose energy we are conscious; pain is a reflex of the overstrained or re- pressed exertion of such a power.” That this theory, which is nearly identical with that of Aristotle, is inadequate to account for all the phenomena of pleasure and pain, has been, I think. conclusively proved by Mr. Mill. With its complete adequacy, however, we need not now concern ourselves; a8 we shall presently see that a different though somewhat allied statement will much better express the facts in the case. Hamilton’s statement, however inadequate, is illustrated by a number of truths which for our present purpose are of importance. A large proportion of our painful states of consciousness are attendant upon the inaction, or what Hamilton less accurately calls the “repressed exertion,” ot certain organic functions. According to the character of the functions in question, these painful states are known as cravings or yearnings. Inaction of the alimentary canal, and that molecular inaction due to deficiency of water in the system, are attended by feelings of hunger and thirst, whicn 328 COSMIC PHILOSOPHY. - [pr ny vary from slight discomfort to intense agony according as the inaction is prolonged, Of. kindred character are the acquired cravings for tobacco, alcohol, and other narcotics. Inaction of the muscles causes great discomfort in children who are compelled to sit still, and grown persons feel similar annoy- ance when the enforced stillness is long enough kept up. Prisoners. kept in dark cells soon feel an intense craving for light, which in time becomes scarcely less intolerable ‘than raging hunger. A similar explanation suffices for the emo- tional yearnings involved in home-sickness, ennui, deprivation of the approval of our fellow-creatures, or in separation from our favourite pursuits, All these painful states are due to the enforced inaction of certain feelings, social or esthetic. And in similar wise, as Mr..Spencer observes, the bitter. grief attendant upon:the death of a friend results from the ideal representation of a future in which certain groups of habitual emotions must remain inactive or unsatisfied by outward expression. | The objection may ha aed that all this is me an sintotetn way of saying that certain pains result from the deprivation of certain pleasures. But since such an objection, in its very. statement, recognizes that certain kinds of unimpeded acti- vity, physical or psychical, are pleasures, it need not disturb us, or lead us to under-estimate the value of Hamilton’s suggestion. Let us note next that excessive action of any function, equally with deficient action, is attended by pain, Local pain results from intensified sensations of heat, light, sound, or pressure; and though it may be in some cases true, as Mr. Spencer asserts, that sweet tastes are not rendcred positively disagreeable by any degree of intensity,’ the alleged fact seems quite contrary to my .own experience, and to that of several other persons whom I have questioned. Other — local pains, as in inflammation and sundry other forms oi disease, are apparently due to increased molecular activity in 1 Spencer, Principles of Psychology, vol. i. p. 276. a cH. xx] GENESIS OF MAN, MORALLY. 329 the parts affected. And the feelings of pain or discomfort both local and systemic, attendant upon over-exercise, over- eating, or excessive use of a narcotic, are to be similarly explained. Thus we may say that pleasure, generally speaking, is “ the concomitant of an activity which is neither too small nor too great,” and we get at the significance of the Epicurean maxim, pndev ayav. But this doctrine, as already hinted, is by no means complete. For, as Mr. Mill and Mr. Spencer ask, “What constitutes a medium activity? What deter- mines that lower limit of pleasurable action bel owwhich there is craving, and that higher limit of pleasurable action above which there is pain?” And furthermore, how happen there to be certain feelings (as among tastes and odours) which are disagreeable in all degrees of intensity, and others that are agreeable in all degrees of intensity? The answer, as Mr. Spencer shows, is to be sought in the study of the past conditions under which feelings have been evolved. If the tentacles of a polyp are rudely struck by some passing or approaching body, the whole polyp contracts violently in such a manner as to throw itself slightly out of the way; but if a fragment of assimilable food, floating by, happens to touch one of the tentacles gently, the tentacle grasps it and draws it slowly down to the polyp’s digestive sac. Now between these contrasted actions there is no such psychical difference as accompanies the similarly con- trasted human actions of taking food and ducking the head to avoid a blow; for the polyp’s contractions, being simply reflex actions of the lowest sort, are unattended by states of consciousness, either agreeable or disagreeable. Nevertheless there is one respect in which the two cases perfectly agree. In both cases there is a seeking of that which is beneficial to the organism, and a shunning of that which is injurious. And while, in the case of the polyp, there is no conscious pleasure or pain, we may fairly surmise that, as soun as any 330 COSMIC PHILOSOPHY. | (er. 11. animal’s psychical life becomes sufficiently complex to be attended by distinct states of consciousness, the presence of that which is beneficial is accompanied by a pleasurable feeling which leads to the seeking of it, while the presence of that which is injurious is accompanied by a painful feeling which leads to the shunning of it. Our surmise is strength- ened as we reconsider the human actions lately enumerated, and observe that the abnormal activity of a function, either in deficiency or in excess, is injurious, while the normal activity of a function in balance with its companion functions is beneficial, As Mr. Spencer says, “in a mutually dependent set of organs having a consensus of functions, the very exist- ence of a special organ having its special function, implies that the absence of its function must cause disturbance of the consensus,—implies too, that its function may be raised to an excess which must cause disturbance of the consensus, —implies, therefore, that maintenance of the consensus goes along with a medium degree of its function.” In accordanca with this view, we may note that hunger and thirst are feelings attendant upon a kind of functional inaction which is harmful, and even fatal if prolonged; that inaction or excessive action of the muscles is injurious as well as pain- ful; that the intense heat and cold, and the violent pressure, which cause distress, will also cause more or less injury, and may cause death ; that the discomfort following repletion and narcosis is the concomitant of a state of things which, if kept up, must end in dyspepsia, or other forms of disease, entailing usually a permanent lowering of nutrition; and that the intense sounds and lights which distress the ear and eye also tend to produce deafness and blindness. And in like manner, the enforced inaction of the social and esthetic feelings, which is attended by mental discomfort, is also attended in the long run by a diminution of the fulness and completeness of psychical life, which in extreme cases. may result in consumption, insanity, or narcotic craving, ou. xx11.] GENESIS OF MAN, MORALLY. 331 It would seem, therefore, that the class of cases upon which Hamilton relied will justify an interpretation much deeper than the one which he proposed for them. They will appa- rently justify us in asserting that pleasure is a state of con- sciousness accompanying modes of activity which tend to increase the fulness of life of an organism, while pain is a state of consciousness accompanying modes of activity which tend to diminish the fulness of life. Before considering the objections to this doctrine,—which, though at first sight formidable, will disappear on further analysis——let us note, with Mr, Spencer, that, on the theory of evolution, “races of sentient creatures could have come into existence under no _ other conditions.” Omitting the cases which, in human psychology, are complicated by the foresight of remote or inconspicuous consequences, Mr. Spencer observes that Pleasure is “a feeling which we seek to bring into con- sciousness and retain there,” while Pain is “a feeling which we seek to get out of consciousness and to keep out.” Hence it follows that “if the states of consciousness which a creature endeavours to maintain are the correlatives of injurious actions, and if the states of consciousness which it endeavours to expel are the correlatives of beneficial actions, it must quickly disappear through persistence in the injurious and avoidance of the beneficial.” In other words, even supposing arace cf animals could come into existence, which should habitually seek baneful actions as pleasurable, and shun useful actions as painful, natural selection would immediately exterminate it. Our supposition is therefore a hibernicism: under the operation of natural selection no such race could xver come into existence. Only those races can exist whose ieelings, on the average, result in actions which are in harmony with environing relations. Accordingly we may rest upon a still deeper and firmer basis our doctrine of pleasure and pain, and assert that Pleasure is a state of gonsciousness accompanying the relatively complete adjust- 332 COSMIO PHILOSOPHY, [er. 1. ment of inner to outer relations, while Pain is a state of consciousness attendant upon the discordance between inuer and outer relations. We may now consider a class of facts which at first seem inconsistent with the theory, but which in reality serve further to illustrate it. Animals now and then perform self- destructive actions under circumstances which make it diffi- cult to suppose that the performance is not pleasurable. Though the majority of vegetable poisons are disagreeable to the taste, yet this is not always the case; and hence animals have been known to perish after a greedy meal upon some noxious herb. But here, as in the case of the moth which, in Tennyson’s phrase, is “shrivelled in a fruitless fire,” there is a new relation in the environment for which there is no corresponding adjustment established in the organism. The cases are like that of the child who ignorantly drinks a sweet poison, or satisfies its desire for muscular activity by climbing out of the window. The dynamic theory of life does not imply the pre-existence of internal relations answer- ing to all possible external relations. Were it so, life would be complete from the outset. For new emergencies there have to be new adjustments. Now manifestly if the whole race of moths could be made to live among lighted candles, one of two things must happen: either there must be gene- rated a tendency to avoid the candles, or the race must be exterminated. If an animal migrates to a district where poisonous herbs abound, its existence can be maintained only on one of two conditions: if it be low in intelligence, a disagreeable taste must be generated, so that the noxious food will be instantly rejected, or the odour must become offensive, so that the taste will be forewarned; but if the anima’ be possessed of high intelligence, like a bird or mamman, it will be enough if the dangerous object is identi- fied by smell or taste, or even by vision or touch, while along with the recognition there occurs an ideal representation o} | * UH. XXI1.] GENESIS OF MAN, MORALLY, 333 danger. Hence it is not necessary to the maintenance of a race like mankind that all poisons should be bitter, or that injurious actions, newly tried, should painfully affect any of the senses. The work of making the needful adjustments is thrown largely upon the cerebrum, with its power of forming ideal sequences like those formerly experienced, and of direct- ing action so as to anticipate them. Here, indeed, we come suddenly upon one of the conditions of luman progressive- ness, as above illustrated. ; We can now begin to see why man finds pleasure in so many kinds of activity which are noxious to himself. In no other animal are the failures of adjustment between pleasur- able and painful states, and beneficial and hurtful actions, so numerous or so conspicuous as in man. Though in the adjustments upon which the maintenauce of life immediately depends, the correspondence is of necessity unimpaired, yet in those less essential adjustments concerned in keeping up the greatest possible fulness of life, there is frequent and lamentable imperfection. Thus,—to take one instance out of a hundred,—we continually see pleasurable states of con- sciousness associated with hurtful actions in the cases of men who ruin themselves by the use of narcotics. The fact that men, who are so much wiser than brutes, should often persist in conduct unworthy of brute intelligence, has long formed the theme of much sage but fruitless moralizing. By Jalvinistic theologians such phenomena were formerly cited in proof of the theory that man is morally the lowest of creatures, having been rendered thoroughly unsound by the eating of the apple in Eden. It is needless to say that science offers a very different explanation. It follows from our inquiry into the causes of organic evolution,! that the adjustments which teygd to maintain the highest fulness of life can be kept up only by natural selection or by direct equili- bration, Now we have already had occasion to notice that in 1 See above, part ii, chap. xii, 334 _ OOSMIC PHILOSOPHY, (PT. Is the human race, partly on account of the extreme complexity of its individual organization, partly on account of super- added social conditions, the action of natural selection is to a great extent checked. I do not allude to the fact that the supremely important human sympathies, which have grown up in the course of social evolution, compel us to protect the idle and intemperate, so that, instead of starving, they are “enabled to multiply at the expense of the capable and in- dustrious.” For far deeper than this lies the circumstance that “there are so many kinds of superiorities which seve- rally enable men to survive, notwithstanding accompanying inferiorities, that natural selection cannot by itself rectify any particular unfitness; especially if, as usually happens, there are coexisting unfitnesses which all vary independently.”* In a race of inferior animals a function in excess is quickly reduced by natural selection, because, owing to the universal slaughter, the highest completeness of life possible to a given grade of organization is required for the mere maintenance of life. But under the conditions surrounding human deve- lopment, a function in excess may remain in excess provided its undue exercise is not such as is incompatible with life, Through countless ages, for example, the feelings which in- sure the maintenance of the race have been strengthened by natural selection, because of their prime importance to every race. But under the conditions of civilized life, the sexual passion has become a function in excess, which natural selec- tion is powerless to reduce, because, although it is probably the source of more crime and misery than any other excessive function, and therefore detracts more from complete individu- ation or the fulness of human life than any other, it is never- theless but seldom incompatible with the maintenance of life. In all such cases, mankind has so many other functions, be- sides the excessive ones, which enable it to subsist and achieve progress in spite of them, that their reduction to the 1 Spencer, op. cit. i. 284, CH, XX11.] GENESIS OF MAN, MORALLY. 335 normal standard is left for the slow process of direct equili- bration. The action of direct equilibration, in turn, is greatly com- plicated, among the progressive races, by the rapid and extensive change of the social environment from age toage. A new set of readjustments needs to be made before the old ones are completed; and the result is that there are always a number of functions somewhat out of balance. When civilization is rapidly progressing, each generation of men is forced into kinds of activity to which the inherited emotional tendencies, and in some cases even the inherited physical con- stitutions, are not thoroughly adapted. Hence the number and variety of pathological phenomena, boti mental and physical, is greater in civilized than in savage communities. As might be expected, the present century, which has wit- nessed a far more extensive revolution in the modes of human activity than any previous age, exhibits numerous instances of these minor failures of adjustment. To take the most conspicuous example,—the progress of science and industry during the past three generations have raised the averave standard of comfortable living so greatly and so suddenly, — that to attain this standard an excessive strain is put upon men’s powers. In many respects, it is harder to live to-day than it was a hundred years ago. As a general rule we are overworked until late in life, in the mere effort to secure tlie means of maintaining life. Not only does this continual overwork entail a serious disturbance of the normal equili- briam between pleasures and pains and the correlative benetits «ud injuries, since it involves the undue exertion of certaix faculties and the undue repression of others, but there is further disturbance due to the specific character of the over- work. Throughout a very large and constantly increasing portion of the community, the excessive labour is intellectual labour ; the abnormal strain comes upon the nervous system. The task of maintaining the correspondence with environing 336 COSMIC PHILOSOPHY. (PT. 1, relations, which in the course of organic evolution has been entrusted more and more largely to the nervous system, and which in the course of social evolution has been thrown more and more upon the cerebrum, has during the past hundred years been thrown upon the cerebrum to a formidable extent. The community, therefore, is suffering not simply from overwork, but from excessive brain-work, in the shape of inordinate thinking and planning, and inordinate anxiety. “Further, it is to be observed that many of the industrial activities which the struggle for existence has thrust on the members of modern societies, are in-door activities,—activi- ties not only not responded to by the feelings inherited from. aboriginal men, but in direct conflict with those more remotely inherited and deeply organized feelings which prompt a varied life in the open air.” Hence manifold dis- turbance. “A sedentary occupation pursued for years in a confined air, regardless of protesting sensations, brings about a degenerate physical state in which the inherited feelings are ereatly out of harmony with the superinduced requirements of the body. Desired foods, originally appropriate, become indigestible. An air pleasure-giving by its freshness to those in vigour, brings colds and rheumatisms. Amounts of exer- tion and excitement naturally healthful and gratifying are found injurious. All which evils, due though they are to con- tinued disregard of the guidance of inherited feelings, come eventually to be mistaken for proofs that the guidance of in- herited feelings is worthless.” } Further to pursue this interesting subject would be to con- vert a set of illustrations, already too elaborately stated, into an unmanageable digression. Summing up the results nov obtained, we see that natural selection, acting less rigidly under the limitations imposed by social evolution, fails to 1 Spencer, op. cit. i. 282, 283. Light is thus thrown upon the misuse of alcohol and tobacco,—one of the most conspicuous of the cases in which men’s physical appetites prompt to actions that are injurious, OH. Xx1!.] GENESIS OF MAN, MORALLY. 337 reduce functions that are in excess, and leaves them to be reduced by direct equilibration. The process is accordingly slow, since direct adaptation to a rapidly changing environ ment is attended by the appearance of minor unfitnesses which further complicate the emotional disturbance, and disarrange the normal relations between incentives and actions. We need not, therefore, be surprised at the fact that men often find pleasure in detrimental activities; nor need we indorse the Puritanic or ascetic theory, suggested partly by the contemplation of this fact, “that painful actions are beneficial and pleasurable actions detrimental.” For if this were to any considerable extent the case, sentient life would inevitably disappear from the face of the earth. The cases which we have cited belong to ethical pathology. And just as pathologic phenomena do not invalidate the laws of physiology, just as the dynamic theory of life is not invali- dated by the fact that mal-adjustments are continually met with, so neither do cases of moral disease invalidate the corollary which inevitably follows from the Doctrine of Evolution, “that pleasures are the incentives to life-support- ing acts, and pains the deterrents from life-destroyiny acts.” We are now prepared to deal with the phenomena of Right and Wrong, and to notice how they become distinguished from the phenomena of Pleasure and Pain. Though the foregoing discussion forms the basis for a general doctrine of morality, it is nevertheless an inadequate basis, until properly supplemented. The existence of a moral sense has purposely been as far as possible unrecognized; for I believe that in Vealing with these complex subjects, little can be accom- =lished, save on the plan of separately cornering the various clements in the problem, and flooring them one by one. Any philosophy of ethics, therefore, which might be founded upon the preceding analysis, could be nothing move than a theory of Hedonism, recognizing no other incentive to proper action than the pleasing of one’s self. By one of the innumerable VOL, II. Z 328 COSMIC PHILOSOPHY. {[Pr. 1. tricks which the misuse of current words plays with the uderstanding, the so-called utilitarian theory has been, and still is, not unfrequently identified with this kind of hedo- nistic philosophy, which is in truth its very antipodes. ‘The error is much like that involved in the accusation of fatalism, commonly hurled at those whe maintain the obvious and harmless assertion that moral actions conform te law. But the difference, comprising the entire difference between the noblest self-sacrifice and the meanest self-fondling, is as follows: In our theory of pleasure and pain, which if taken as ultimate would be hedonism, the well-veing of the com- munity has been as far as possible omitted from the account. _ Wherever I have introduced references to social phenomena, I have considered them only in their effects upon the fulness of life of the individual. In dealing with the incentives to action in a race of brute animals, the foregoing considerations would be sufficient. But in the so-called utilitarian theory as it is now to be expounded, the well-being of the com- munity, eveu when incompatible with that of the individual, is the all-important consideration. While the actions deemed pleasurable are those which conduce to the fulness of life of the Individual, the actions deemed right are those which conduce to the fulness of life of the Community. And while the actions deemed painful are those which detract from the fulness of life of the Individual, the actions deemed wrong are those which detract from the fulness of life of the Community. According to utilitarianism, therefore, as here expounded, the conduct approved as moral is the disinterested service of the commu- nity, and the conduct stigmatized as immoral is the selfish preference of individual interests to those of the community. And bearivg in mind that the community, which primevally comprise only the little tribe, has by long-continued social integration come to comprise the entire human race, we have the ultimate theoiem of the utilitarian philosophy, as properiy understood, that actions morally right are those which are cH. Xx11.] GENESIS OF MAN, MORALLY. 339 beneficial to Humanity, while actions morally wrong are those which are detrimental to Humanity. Are we to maintain, then, that when we approve of certain actions, we do so because we consciously and deliberately reason out, in each particular case, the conclusion that these actions are beneficial to mankind? By no means. Not only is it that the highest science cannot always enable us to say’ surely of a given action that it is useful to mankind, but it is also that we do not stop to apply science to the matter at all. We approve of certain actions and disapprove of certain actions quite instinctively. We shrink from stealing or lying as we shrink from burning our fingers; and we no more stop to frame the theorem that stealing and lying, if universally practised, must entail social dissolution and @ reversion to primeval barbarism, than we stop to frame the theorem that frequent burning of the fingers must entail an incapacity for efficient manual operations. In short, there is in our psychical structure a moral sense which is as quickly and directly hurt by wrong-doing or the idea of wrong-doing as our tactile sense is hurt by stinging. Shall we, then, maintain, as a corollary from the Doctrine of Evolution, that our moral sense is due to the organic registration, through countless ages, of deliberate inferences that some actions benefit Humanity, while others injure it? Shall we say that the primeval savage began by reason- ing his way to the conclusion that if treachery were to be generally allowed, within the limits of the tribe, then the tribe must succumb in the struggle for existence to other tribes in which treachery was forbidden; and that, by a gradual organization of such inductions from experience, our moral sense has slowly arisen? This position is no more venable than the other. Mr. Richard Hutton and Mr. St. George Mivart would seem to have attributed to Mr. Spencer some such doctrine. But Mr. Spencer is too profound a thinker to ignore so completely the conditions under which Z2 340 COSMIC PHILOSOPHY. Ph permanent emotional states are generated. Our moral sense has arisen in no such way. But to understand the way in which it has arisen, we must recur to our fundamental problem, and seek for the conditions which first enabled social evolution, as distinguished from organic evolution, to start upon its career. It is now time to propose an answer to the question, already twice suggested and partly answered, How did social evolution originate? Starting from the researches of Sir Henry Maine, which are supported by those of Messrs, Tylor, M‘Lennan, and Lubbock, we have come to the conclu- sion that it originated when families, temporarily organized among all the higher gregarious mammals, became in the case of the highest mammal permanently organized. Start- ing from the deductions of Mr. Wallace, we have seen reason for believing that civilization originated when in the highest mammal variations in intelligence became so much more im- portant than variations in physical structure that they began to be seized upon by natural selection to the relative exclu- sion of the latter. In the permanent family we have the germ of society. In the response to outer relations by psychical changes, which almost completely subordinate physical changes, we have the germ of civilization. Let us now take a step in advance of previous speculation,! and see what can be done by combining these two theorems, so that the permanent organization of families and tlie complex intelligence of the highest mammal will appear in their causal relations to each other. Many mammals are gregarious, and gregariousness implies 1 The latest writer upon these subjects is inclined to give up the problem asinsoluble. “I at least find it difficult to conceive of men, at all like the present men, unless existing in something like families, that is, in groups avowedly connected, at least on the mother’s side, and probably always wita a vestige of connection, more or less, on the father’s side, and unless these groups were, like many animals, gregarious, under a leader more or less fixed. lé is almost beyond imagination how man, as we know man, could by any sort of process have gained this step in civilization.”—Bagehot, Physics and Politics, p. 136.

But gregariousness differs from sociality by the absence of definitive family relationships, except during the brief and intermittent periods in which there are helpless offspring to be protected. Now it might be maintained that the com- plex intelligence of the highest mammal led him vaguely to recognize the advantage of associating in more and more permanent groups for the sake of mutual protection. From this point of view Mr. Darwin argues that men were ori- ginally a race of weak and mild creatures like chimpan- zees, and not a race of strong and ferocious creatures like gorillas, and were accordingly forced to combine because unable to defend themselves singly. It is undeniable that man is, relatively to his size, a weak animal; and there is much value in Mr. Darwin’s suggestion in so far as it goes to explain the origin of gregariousness among those primates who were the ancestors of man. Nevertheless, it can hardly be said to explain Sociality as distinguished from Gregari- ousness. It may also be argued that the superior sagacity even of the lowest savage makes him quite a formidable antagonist to animals much more powerful than himself. Besides, the study of savage life brings out results at vari- ance with the notion of man’s primitive gentleness. « . x x ta Ne * * > me a epee were 7 FF ivy, + ‘ as : MSE EM he RE SAAR ARAR SS EAE E ARBAB ARE Ke Pas fy ts os “4 a ies a re esas * = = Se 22 aA ay < AAAS Paty) es ama SRS Dee = Si eet ce - 8 Toys c~s AD ‘A Mee é ¥ is ‘4 P27 ee eee ee ieee ea wa eee de Pry irrs. td daad Shae Sagdadeda ant é * tates a -- é 4 Sdnpedhenen. 7 PEPE. ieee ‘2 oA fs bod s <¢ z fetvecas dd ta dth did dd SEAT Ld lidddd Fidddds J . “4 é sa 4
