THE MORALITY OF NATURE.
The work of
The leading ideas of
This being Darwin’s first proposition, his second is that as soon as the mental faculties of a species become highly developed, as they are in man, the social instinct wilt necessarily lead, as every other unsatisfied instinct does, to a sense of dissatisfaction, or even misery, as often as the individual, reasoning about its past actions, sees that in sonic of them “the enduring and always present social instinct had yielded to some other Instinct, at the time stronger, but neither enduring nor leaving behind it a very vivid impression.” For Darwin the moral sense Is thus not the mysterious gift of unknown origin which it was for Kant “Any animal whatever,” he says, “endowed with well-marked social instincts, the parental and filial affections being here included, would inevitably acquire a moral sense, or conscience [Kant’s ‘knowledge of duty’], as soon as its intellectual powers had become as well, or nearly as well, developed as in man” (ch. iv. pp. 149-150).
To these two fundamental propositions
Having thus stated the substance of his views in four definite propositions,
Considering nest human morality, Darwin remarks that although man, such as he now exists, has but few special instincts, he nevertheless is a sociable being who must have retained from an extremely remote period some degree of instinctive love and sympathy for his fellows. These feelings act as an impulsive instinct, which is assisted by reason, experience, and the desire of approbation. Thus the social instincts, which must have been acquired by man in a very rude state, and probably even by his ape-like progenitors, still give the impulse for some of his best actions.” The remainder is the result of a steadily growing intelligence and collective education.
It is evident that these views are correct only if we are ready to recognize that the intellectual faculties of animals differ from those of man in degree, but not in their essence. But this is admitted now by most students of comparative psychology; and the attempts which have been made lately to establish “a gulf” between the instincts and the Intellectual faculties of man and those of animals have not attained their end. However, It does not follow from this resemblance that the moral instincts developed in different species, and the less so in species belonging to two different classes of animals, should be Identical. If we compare insects with mammals, we must never forget that the lines of their development have diverged at it very early period of animal evolution. The consequence was that a deep physiological differentiation between separate portions of the same species took place with the ants, the bees, the wasps, &c., corresponding to a permanent physiological division of labor between their females, their males, and their workers—a division of which there is no trace among mammals. Therefore it seems almost impossible to ask men to judge of the morality of the worker-bees when they kill the males in their hive; and this is why the illustration of
The social instinct is thus, in
This caution was fully justified, because in other places he pointed out that the social instinct must be a separate instinct in itself, different from the others—an instinct which has been developed by natural selection for its own sake, as it was useful for the well-being and the preservation of the species. It is so fundamental that when it runs against another instinct, even one so strong as the attachment of the parents to their offspring, it often takes the upper hand. Birds, when the time has come for their autumn migration, will leave behind their tender young, not yet old enough for a prolonged flight, and follow their comrades (pp. 164-165).
To this striking illustration I may also add that the social Instinct Is strongly developed with many tower animals, such as the land-crabs, or the Molucca crab; as also with certain fishes, with whom it hardly could be considered as an extension of the filial or parental feelings. In these cases it appears rather as an extension of the brotherly or sisterly relations, or feelings of comradeship, which probably develop each time that a considerable number of young animals, having been hatched at a given place and at a given moment, continue to live together—whether they are with their parents or not. It would seem, therefore, more correct to consider the social and the parental instincts as two closely connected instincts, of which the former is perhaps the earlier, and therefore the stronger, and which both go hand in hand in the evolution of the animal world. Both are favored by natural selection, which, as soon as they come into conflict, keeps the balance between the two, for the ultimate good of the species.
The most important point in the ethical theory of Darwin is, of course, his explanation of the moral conscience of man and his sense of remorse anti duty. This point has always been the stumbling-block of all ethical theories. Kant, as is known, utterly failed, in his otherwise so beautifully written work on morality, to establish why his “categorical imperative” should be obeyed at all, unless such be the will of a supreme power. We may admit that Kant’s “moral law,” if we slightly alter its formula, while we maintain its spirit, is a necessary conclusion of the human reason. We certainly object to the metaphysical form which Kant gate it; but, after all, it substance is equity, justice. And, if we translate the metaphysical language of Kant into the concrete language of inductive science, we may find points of contact between his conception of the origin of the moral law and the naturalist's view concerning the development of the moral sense. But this is only one-half of the problem. Supposing, for the sake of argument, that, “pure reason,” free from all observation, all feeling, and all instinct, in virtue of its inherent properties, should necessarily come to formulate a law of justice similar to Kant’s Imperative, and granting that no reasoning being could ever come to any other conclusion, because such are the Inherent properties of reason—granting all this, and fully recognizing at the same time the elevating character of Kant’s moral philosophy, the great question of all ethics remains, nevertheless, in full: “Why should man obey the moral law, or principle, formulated by his reason?” Or, at least, “Whence that feeling of obligation which men are experiencing?"
Several critics of Kant’s ethical philosophy have already pointed out that it left this great fundamental question unsolved. But they might have added also that Kant himself bad recognized his incapacity of solving it. After having thought intensely upon the subject, and written about it for four years, he acknowledged in his Philosophical Theory of Religion (
Intuitive philosophy having thus acknowledged its incapacity to solve the problem, let us see how
We have thus, for the first time, an explanation of the sense of duty on a natural basis. True, that it runs counter to the Ideas that are current now about animal and human nature; but it is correct. Nearly all ethical writers have hitherto started with the unproved postulate that the strongest of all the Instincts of man, and the more so of animals, is the self-preservation instinct, which, owing to a certain looseness of their terminology, they have identified, in man, with self-assertion, or egoism properly speaking. This instinct, which they conceived as including, on the one side, such primary impulses as self-defence, self-preservation, and the very act of satisfying hunger, and, on the other side, such derivative feelings as the longing for domination, greed, hatred, the desire of revenge, and so on—this compound and heterogeneous aggregate of instincts and feelings they represented as an all-pervading and all-powerful force, which finds no contradiction in animal and human nature, excepting in a certain feeling of benevolence or mercy. The consequence of such a view was that, once human nature was recognized as such, there obviously remained nothing but to lay a special stress upon the softening influence of those moral teachers who appealed to mercy, borrowing the spirit of their teachings and the impressiveness of their words from a world that lies outside nature—outside and above the world which is accessible to our senses. And if one refused to accept this view, the only alternate issue was to attribute, as Hobbes and his followers did, a special importance to the coercive action of the state, inspired by genial lawgivers—which meant, of course, merely to shift the extra-natural inspiration from the religious preacher to the law-maker.
Beginning with the Middle Ages, the founders of ethical schools, for the most part ignorant of nature, to the study of which they preferred metaphysics, had represented the self-assertive instincts of the individual as the very condition of its physical existence. To obey their promptings was considered as the law of nature, the neglect of which would lead to a sure defeat and to the ultimate disappearance of the species. Therefore, to combat these egotistic promptings was possible only if man called to his aid the supernatural forces. The triumph of moral principles was thus represented as a triumph of man over nature, which he may hope to achieve only with an aid from without, coming as a reward for his humility. They told us, for instance, that there is no greater virtue, no greater triumph of the spiritual over the natural, than self- sacrifice for the welfare of our fellow- men. But the fact is that self-sacrifice In the interest of an ants’ nest, for the safety of a group of birds, or the security of a drove of cattle, a herd of antelopes, or a band of monkeys, is a zoological fact of everyday occurrence is Nature—a fact for which hundreds upon hundreds of animal species require nothing else but natural sympathy with their fellow-creatures, the sensation of full vital energy, and a constant habit of mutual aid. Darwin, who knew nature, had the courage boldly to assert that of the two instincts—the social and the individual—it is the former which is the stronger, the more persistent, and the more permanently present. And he was right. The instinct of mutual aid pervades the animal world, because natural selection works for maintaining and further developing it, and pitilessly destroys those species which lose it in the great struggle for life which every animal species carries on against the hostile agencies of climate, surroundings, and natural enemies, big and small, those species which most consistently carry out the principle of mutual support have the best chance to survive, while the others die out. And the same great principle is confirmed by the history of mankind.
It is most remarkable that in representing the social instinct under this aspect we return, in fact, to what Bacon, the great founder of inductive science, had perceived. In his programme of the work to be done by the next generations with the aid of the inductive method, in The Great Instauration, he wrote:
All things are endued with an appetite for two kinds of good—the one as a thing is a whole in itself, the other as it is a part of some greater whole; and this latter is more worthy and more powerful than the other, as it tends to the conservation of a more ample form. The first may be called individual, or self-good, and the latter, good of communion. . . . And thus it generally happens that the conservation of the more general form regulates the appetites.
It may be asked, of course, whether such a conception agrees with the theory of natural selection, according to which struggle for life, within the species, was considered a necessary condition for the appearance of new species, and for evolution altogether Having already touched elsewhere upon this question, I will not enter here into its discussion, and will only add the following remark. Immediately after the appearance of
Nature has thus to be recognized as the first ethical teacher of man. The social instinct, innate in men as well as it is in all the sociable animals, is the origin of all ethical conceptions and all the subsequent ethical development.
The starting-point for a work on ethics, from the evolution point of view, was thus given by
This applies, as is known, to Herbert Spencer. It would certainly be out of place here to discuss his ethics as a whole, the more so as it contains portions of great value, which could not be dealt with incidentally. But it is only the more necessary to mention that the ethical philosophy of Spencer was constructed on a different plan. The ethical and sociological portions of his Synthetic Philosophy were worked out, in the main, long before the appearance of
This admission—which, by the way, it would be difficult to support by modern investigation—puts its stamp upon all the further developments of Spencer's ethics. The history of mankind is divided into two stages: the “militant,” which has prevailed till now, and the “industrial,” which is slowly coming in at the present time, and both of which require their own special morality. Under the militant stage coercion was more than necessary: it was the very condition of progress. It was also necessary during that stage that the individual should be sacrificed to the community, and that a corresponding moral code should be elaborated. And this double necessity of coercion and sacrifice of the individual must continue to exist so long as the industrial state has not entirely taken the place of the militant state. Two different kinds of ethics, appropriated to these two different states, are thus admitted (Data, § 48-50), and such an admission leads to many conclusions which stand or fall with It. Moral science appears, therefore, as the search for a compromise between a code of enmity and a code of amity—between equality and inequality (25). And as there is no issue out of that conflict—because the coming of the industrial state will only be possible after the cessation of the conflict—there remains nothing to be done but to add a certain benevolence (some, but not too much) to the strictly individualistic principles which Spencer considers the embodiment of retributive Justice. Therefore all his attempts to establish a standard of morality necessarily fall, and he finally comes to the unexpected conclusion that all the moral systems, philosophical and religious, complete each other; while Darwin’s idea was, on the contrary, that sociability and the power of the social instinct are the common stock, out of which all systems and teachings of morality, including the ethical portions of the different religions, have originated.
It may be added, in conclusion, that although Spencer’s conception of the struggle between egoism and altruism bears a great resemblance to Comte’s treatment of this subject, the views of the Postivist philosopher concerning the social instinct—notwithstanding all his opposition to the transmutation of species—were nearer to the above-mentioned views of
As already said, none of the immediate followers of
Primitive man lived in close intimacy with animals. With some of them he probably shared the shelters under the rocks, occasionally the caverns, and very often food. Not more than a hundred years ago the natives of Siberia and
The first thing which our children learn in natural history is something about the beasts of prey—the lions and the tigers. But the first thing which primitive savages must have learned about nature was that it represents a vast agglomeration of animal clans and tribes: the ape tribe, so nearly related to man, the ever-prowling wolf tribe, the knowing, chattering bird tribe, the ever-busy insect tribe, and so on. For them the animals were an extension of their own kin—only so much wiser than themselves. And the first vague generalization which men must have made about nature—so vague as to hardly differ from a mere impression—was that the living being and his clan or tribe are inseparable. We can separate them—they could not: unit it seems even doubtful whether they could think of life otherwise than within a clan or a tribe.
Such an impression of nature was unavoidable. Among his nearest congeners—the monkeys and the apes—man saw hundreds of species living in large societies, united together within each group by the closest bonds. He saw how they supported each other during their foraging expeditions. how they combined against their common enemies, and rendered each other all sorts of small services, such as the picking of thorns from each other’s fur, the nestling together in cold weather, and so on. Of course they often quarrelled; but there was more noise in these quarrels than serious harm, and at times, in case of danger, they displayed the most striking mutual attachment; to say nothing of the strong devotion of the mothers to their young ones, which they have in common with all the animals. Sociability was thus the rule with the monkey tribe; and if there are now two species of big apes, the gorilla and the orang-utang. which are not sociable, and keep in smell families only, the very limited sizes of the areas they inhabit are a proof of their being now decaying species—decaying perhaps, on account of the merciless war which men have waged against them in consequence of the very resemblance between the two species.
Primitive man saw, next, that even among the carnivorous beasts, which live by killing other animals, there is one general and invariable rule: They never kill each other. Some of them are very sociable—such are all the dog tribe: the jackals, the dholes or kholzun dogs, the hyænas. Some others prefer to live in small families; but even among these last the more intelligent ones—the lions and the leopards—occasionally join together for hunting, like the dog tribe. And as to those few which lead—nowadays, at least—a quite solitary life in small families, so that even the females with their cubs will often keep separate from the males, the same general rule of nature prevails among them: they do not kill each other. Even now, when the myriads of ruminants which formerly peopled the prairies have been exterminated, and the tigers live mainly on man's herds, and are compelled, therefore, to keep close to the villages, every one to its own domain—even now the natives of India will tell us that somehow the tigers manage to keep to their separate domains without fighting bloody internecine wars for securing them, Besides, it appears extremely probable that even those few animals which now lead a solitary existence—such as the tigers, the smaller species of the cat tribe (nearly all nocturnal), the hears, the genets, most weasels, the marten tribe, the hedgehog, and a few others—were not always solitary creatures. For some of them we have positive evidence that they remained sociable so long as they escaped extermination by man, and we have reason to believe that nearly all of them were in the same conditions in times past. But even if there always existed a few unsociable species, the fact is that man has always considered them an exception.
The lesson of nature was, thus, that even the strongest beasts are bound to combine. And that man who had witnessed once in his life an attack of wild dogs, or dholes, upon the biggest beasts of prey, certainly realized, once and for ever, the irresistible force of the tribal unions, and the confidence and courage with which they inspire every individual. Man made divinities of these dogs, and worshipped them, trying by all sorts of magic to acquire their courage.
In the prairies and the woods our earliest ancestors saw myriads of animals, all living in clans and tribes. Countless herds of red-deer, fallow deer, reindeer, gazelles and antelopes, thousands of droves of buffaloes and legions of wild horses, wild donkeys, quaggas, zebras, and so on, were moving over the boundless plains, peacefully grazing side by side. Even the dreary plateaus had their herds of llamas and wild camels. And when man approached these animals, he soon realized how closely connected all these beings were in their respective droves or herds. Even when they seemed fully absorbed in grazing, and apparently took no notice of the others, they closely watched each other’s movements, always ready to join in some common action. Man saw that all the deer tribe, whether they graze or merely gambol, always keep sentries, which never release their watchfulness and never are late to signal the approach of a beast of prey; he knew how, in case of a sudden attack, the males and the females would encircle their young ones and face the enemy, exposing their lives for the safety of the feeble ones; and how, even with such timid creatures as the antelopes, or the fallow deer, the old males would often sacrifice themselves in order to cover the retreat of the herd. Man knew all that which we ignore or easily forget, and he repeated it in his tales, embellishing the acts of courage and self-sacrifice with his primitive poetry, or mimicking them in his religious tribal dances. Still less could he ignore the great migrations of animals because be followed them—Just as the Chukchi follows still the herds of the wild reindeer, when the clouds of mosquitoes drive them from one place of the Chukchi peninsula to another, or as the Lapp follows the herds of his halt-domesticated reindeer In their wanderings, over which he has no control. And If we, with all our book-learning, feel unable to understand how animals scattered over a wide territory can warn each other so us to bring their thousands to a given spot before they begin their march north, south, or west, our ancestors, who considered the animals as beings so much wiser than themselves, saw no difficulty in explaining that intercourse. For them all animals—beasts, birds, and fishes alike—were in continual communication, warning each other by means of hardly perceptible signs or sounds, informing one another about all sorts of events, and thus constituting one vast community, which bad Its own habits and rules of propriety and good behavior. Even to-day deep traces of that conception of nature survive in the folklore of all nations.
From the populous, animated, and gay villages of the marmots, the prairie dogs, the jerboas, the hamsters, and so on, and from the colonies of that silent sage, the beaver, with which the Postglacial rivers were thickly studded, primitive man, who himself had begun as a nomad forest-dweller, could learn the advantages of settled life, permanent dwellings, and labor in common. Even now we can see how the nomad cattle-breeders of
The birds, in their turn—almost every one of their species—gave our ancestors a lesson of the most intimate sociability, of the joys of social life, and its enormous advantages. It certainly did not escape the attention of that, even among the birds of prey, many species of falcons are extremely sociable, and that even some eagles combine for hunting; while the docks of kites will sometimes chase the strongest eagle and get bold of its spoil. And they saw, of course, many a time, how the smallest birds, if they are numerous enough, overcome their first terror at the sight of a hawk, and chase it, immensely enjoying this kind of sport
The nesting associations of aquatic birds, and their unanimity in defending their young broods and eggs, were well known to man. He knew that as soon as he approached the shore of a lake where thousands of birds belonging to different species were nesting, his appearance would be signalled at once; how, the moment he would set his foot upon their grounds, hundreds of birds would circle and fly round him, skim over his face, bewilder him by the flapping of their wings, deafen him by their cries, and often compel him to retreat. Man knew this only too well, for his very existence in the early summer depended upon his capacity to resist such a combined attack of the winged tribe. And then the joy of life in the autumn societies of the bird-youngsters was certainly familiar to people who themselves lived in the woods and by the side of the forest brooks. Who knows if the very idea of wide tribal unions, or, at least, of those great tribal hunts (abà with the Mongols, kadà with the Tunguses), which are rent fêtes, lasting a couple of months every autumn, was not suggested by such autumn gatherings of the birds, in which so many widely different species join together, spending a few hours every day in providing their food, and their chattering and fluttering about the remainder of the time?
Man knew also, of course, the gay play of animals, the sports in which several species delight, the concerts and dances of some others; the flights which certain species perform in the evenings, sometimes with a wonderful art and elaboration; the noisy meetings which are held by the swallows mid other migrating birds, for years in succession, on the same spot, before they start on their long journeys south. And how often man must have stood in bewilderment as he saw the immense migrating columns of birds passing over his head for many hours in succession. The “brute savage” knew and meditated on all these beauties of nature, which we have forgotten in our towns, and which we do not even find in our “natural history” books, compiled for teaching anything but life; while the narratives of the great explorers—the Humboldts, the Audubons, the Azaras, the Brehms, of which every page was a picture of the real life of nature, are mouldering in our libraries.
In those times the wide world of the running waters and lakes was not a sealed book for man. He was familiar with its inhabitants as well. Even now many semi-savage natives of Africa and
The fishes, their shoals, and the ways they play in the transparent waters, exploring them by their scouts before they move in a given direction, must have deeply impressed man from a remote antiquity. Traces of this impression are found in folklore in many parts of the globe. Thus, for instance, Dekanawideh, the legendary lawgiver of the Five Nations of the Red Indians, who is supposed to have given them the class organization, is represented as having retired first to meditate in contact with nature. He “reached the side of a smooth, clear, running stream, transparent and full of fishes. He sat down, reclining on the sloping bank, gazing intent into the waters, watching the ashes playing about in complete harmony. . . .“ Thereupon he conceived the scheme of dividing his people into gentes and classes, or totems.
Altogether, for the primitive savage, animals are mysterious, problematic beings, possessed of a wide knowledge of the things of nature. They know much more than they are ready to tell us. In some way or another, by the aid of senses much more refined than ours, and by telling to each other all that they notice in their rambles and flights, they know everything, for miles round. And if man has been “just” towards them, they will warn him of a coming danger, as they warn each other; but they will take no heed of him if he has not been straightforward in his actions. Snakes and birds (the owl is a leader of the snakes), mammals and insects, lizards and fishes—all understand each other, and continually communicate their observations to one another. They all belong to one brotherhood, into which they may, in some cases, admit man.
Inside this vast brotherhood there are, of course, the still closer brother-hoods of beings “of one blood.” The monkeys, the bears, the wolves, the elephants and the rhinoceroses, most ruminants, the hares and most of the rodents, the crocodiles, and so on, perfectly know their own kin, and they will not tolerate any one of their relatives to be slaughtered by man without taking, in one way or another, honest revenge. This conception must have had an extremely remote origin, it must have grown at a time when man had not yet become omnivorous (which, I am inclined to think, must have happened during the Glacial period), and had not yet begun to hunt animals for food. However, the same conception has been retained clown to the present time. Even now, when a savage is hunting, he is bound to respect certain rules of propriety towards the animals, and he must perform certain expiatory ceremonies after his hunt. Most of these ceremonies are rigorously enacted, even nowadays in the savage clans, especially as regards those species which are considered the allies of man.
It is well known that two men belonging to two different clans or tribes can become brothers by mixing the blood of the two, obtained from small incisions made for that purpose. To enter into such a union was quite habitual in olden times, and we learn from the folklore of all nations, and especially the sagas, how religiously such a brotherhood was observed. But it was also quite habitual for man to enter into brotherhood with some animal. The tales continually mention it. An animal asks a hunter to spare it and if the hunter accedes to the demand the two become brothers. And then the monkey, the bear, the doe, the bird, the crocodile, or the bee—any one of the sociable animals—will take all possible care of the man-brother in the critical circumstances of his life, sending his or her animal brothers of different tribes to warn him or help him out of a difficulty. And if the warning comes too late, or is misunderstood, and he loses his life, they all will try to bring him back to life, and if they fall they will take the due revenge, just as if the man had been one of their own kin.
When I journeyed in
The idea of “Justice,” conceived at its origin as revenge, is thus connected with observations made on animals. But it appears extremely probable that the idea of reward for “just” and “unjust” treatment must also have originated, with primitive mankind, from the idea that animals take revenge if they have not been properly treated by man, and repay kindness by kindness. This idea is so deeply rooted in the minds of the savages all over the world that it may be considered as one of the most primitive conceptions of mankind. Extended from a few animals to all of them, it soon embodied the whole of nature—the trees and the forests, the rivers and the seas, time Locks and the mountains, which are all living. Gradually it grew to be a conception of the great whole, bound together by certain links of mutual support, which watches all the actions of the living beings, and, owing to that solidarity in the universe, undertakes the revenge of wrong deeds. It became the conception of time Eumenides and the Moirai of the Greeks, the Parcae of the Romans, and especially the Karma of the Hindoos. The Greek legend of the cranes of Ibikus, which links together man and birds, and countless Eastern legends are poetical embodiments of the same conception,
This is what primitive man saw in nature and learned from it. With our scholastic education, which has systematically ignored nature and has tried to explain its most common facts by metaphysical subtleties, we began to forget that lesson. But for our Stone Age ancestors sociability and mutual aid within the tribe must have been a fact so general in nature, so habitual, and so common, that they certainly could not imagine life under another aspect. The conception of an isolated being is a later product of civilization—an abstraction, which it took ages to develop in the human race. To a primitive man isolated life seems so strange, so much out of the usual course of nature, that when he sees a tiger, a badger, a shrew-mouse, or a kingfisher leading a solitary existence, or when he notices a tree that stands alone, far from the forest, he creates a legend to explain this strange occurrence. He makes no legends to explain life in societies, but he has one for every case of solitude. The hermit, if he is not a sage or a wizard, is in most cases an outcast of animal society. He has done something so contrary to the ordinary run of life that they have thrown him out. Very often he is a sorcerer, who has the command of all sorts of dangerous powers, and has something to do with the pestilential corpses which sow disease in the world. This is why he prowls at night. prosecuting his wicked designs under the cover of darkness. All other beings in nature are sociable, and human thought runs in this channel. Sociable life—that is, we, not I—is, in the eyes of primitive man, the normal form of life. It is life itself. Therefore “We” must have been the normal form of thinking for primitive man: a “category” of his understanding, as Kant might have said. And not even “We,” which is still too personal, because it represents a multiplication of the “I's,” but rather such expressions as “the men of the beaver tribe,” “the kangaroo men,” or “the turtles.” This was the primitive form of thinking, which nature impressed upon the mind of man.
Here, in that identification, or, we might even say, in this absorption of the “I” by the tribe, lies the root of all ethical thought. The self-asserting “Individual” came much later on. Even now, with the lower savages, the “individual” hardly exists at all. It is the tribe, with its hard-and-fast rules, superstitions, taboos, habits, and interests, which is always present in the mind of the child of nature. And in that constant, ever-present identification of the unit with the whole, lies the substratum of all ethics, the germ out of which all the subsequent conceptions of justice, and the still higher conceptions of morality, grew up in the course of evolution.
But these further steps, as well as the various aspects of sociability itself, and their teachings, will have to be discussed separately on some other occasion.

 The incapacity of an ant, a dog, or a cat to make a discovery, or to hit upon the correct solution of a difficulty, are not proofs of an essential difference between the intelligence of men and that of these animals, because the same want of inventiveness is continually met with in men as well. Like the ant in one of Lubbock’s experiments, thousands of men who had not been already familiar with bridges would spend their forces in the effort of crossing a brook, or a ravine before they would try to bridge it. And, on the other band, the collective intelligence of an ant’s nest or a beehive—one individual to the thousand hitting upon the correct solution, and the others imitating it—solves difficulties much greater than these upon which the individual ant, or bee, or cat has so ludicrously failed, The bees at the Paris Exhibition, and their devices to prevent being disturbed in their work, or any one of the well-known facts of inventiveness among the bees, the ants, the wolves hunting together, are instances in point.

 “On the Dignity and Advancement of Learning,” Book VII, chap. I. (p. 270 of J. Devey’s edition in Bohn's Library), we certainly find Bacon’s arguments in favor of this idea insufficient; but he was only establishing the outlines or a science, which had to be worked out by his followers. In another place he returns to the same idea. He speaks of “two appetites [instincts] of the creatures. (1) that of self-preservation and defence, and (2) that of multiplying and propagating,” and he adds: “the latter, which is active, seems stronger and more worthy than the former, which is passive.”
