Yet let us not forget that this same English temper is shown not only in warfare, not only in adventure in the physical world, but also in the greater, and—may we not say?—equally arduous tasks of peace. For to build up is even yet more difficult than to pull down, to create new life a still more difficult and complex task than to destroy it. Our English habits of restless adventure, of latent revolt subdued to the ends of law and order, of uncontrollable freedom and independence, are even more fruitful here, in the organisation of the progressive tasks of life, than they are in the organisation of the tasks of war.
That is the spirit in which these essays have been written by an Englishman of English stock in the narrowest sense, whose national and family instincts of independence and warfare have been transmuted into a preoccupation with the more constructive tasks of life. It is a spirit which may give to these little essays—mostly produced while war was in progress—a certain unity which was not designed when I wrote them.

EVOLUTION AND WAR
The Great War of to-day has rendered acute the question of the place of warfare in Nature and the effect of war on the human race. These have long been debated problems concerning which there is no complete agreement. But until we make up our minds on these fundamental questions we can gain no solid ground from which to face serenely, or at all events firmly, the crisis through which mankind is now passing.
It has been widely held that war has played an essential part in the evolutionary struggle for survival among our animal ancestors, that war has been a factor of the first importance in the social development of primitive human races, and that war always will be an essential method of preserving the human virtues even in the highest civilisation. It must be observed that these are three separate and quite distinct propositions. It is possible to accept one, or even two, of them without affirming them all. If we wish to clear our minds of confusion on this matter, so vital to our civilisation, we must face each of the questions by itself.
It has sometimes been maintained—never more energetically than to-day, especially among the nations which most eagerly entered the present conflict—that war is a biological necessity. War, we are told, is a manifestation of the "Struggle for Life"; it is the inevitable application to mankind of the Darwinian "law" of natural selection. There are, however, two capital and final objections to this view. On the one hand it is not supported by anything that Darwin himself said, and on the other hand it is denied as a fact by those authorities on natural history who speak with most knowledge. That Darwin regarded war as an insignificant or even non-existent part of natural selection must be clear to all who have read his books. He was careful to state that he used the term "struggle for existence" in a "metaphorical sense," and the dominant factors in the struggle for existence, as Darwin understood it, were natural suitability to the organic and inorganic environment and the capacity for adaptation to circumstances; one species flourishes while a less efficient species living alongside it languishes, yet they may never come in actual contact and there is nothing in the least approaching human warfare. The conditions much more resemble what, among ourselves, we may see in business, where the better equipped species, that is to say, the big capitalist, flourishes, while the less well equipped species, the small capitalist, succumbs. Mr. Chalmers Mitchell, Secretary of the London Zoological Society and familiar with the habits of animals, has lately emphasised the contention of Darwin and shown that even the most widely current notions of the extermination of one species by another have no foundation in fact.2 Thus the thylacine or Tasmanian wolf, the fiercest of the marsupials, has been entirely driven out of Australia and its place taken by a later and higher animal, of the dog family, the dingo. But there is not the slightest reason to believe that the dingo ever made war on the thylacine. If there was any struggle at all it was a common struggle against the environment, in which the dingo, by superior intelligence in finding food and rearing young, and by greater resisting power to climate and disease, was able to succeed where the thylacine failed. Again, the supposed war of extermination waged in Europe by the brown rat against the black rat is (as Chalmers Mitchell points out) pure fiction. In England, where this war is said to have been ferociously waged, both rats exist and flourish, and under conditions which do not usually even bring them into competition with each other. The black rat (Mus rattus) is smaller than the other, but more active and a better climber; he is the rat of the barn and the granary. The brown or Norway rat (Mus decumanus) is larger but less active, a burrower rather than a climber, and though both rats are omnivorous the brown rat is more especially a scavenger; he is the rat of sewers and drains. The black rat came to Northern Europe first—both of them probably being Asiatic animals—and has no doubt been to some extent replaced by the brown rat, who has been specially favoured by the modern extension of drains and sewers, which exactly suit his peculiar tastes. But each flourishes in his own environment; neither of them is adapted to the other's environment; there is no war between them, nor any occasion for war, for they do not really come into competition with each other. The cockroaches, or "blackbeetles," furnish another example. These pests are comparatively modern and their great migrations in recent times are largely due to the activity of human commerce. There are three main species of cockroach—the Oriental, the American, and the German (or Croton bug)—and they flourish near together in many countries, though not with equal success, for while in England the Oriental is most prosperous, in America the German cockroach is most abundant. They are seldom found in actual association, each is best adapted to a particular environment; there is no reason to suppose that they fight. It is so throughout Nature. Animals may utilise other species as food; but that is true of even, the most peaceable and civilised human races. The struggle for existence means that one species is more favoured by circumstances than another species; there is not the remotest resemblance anywhere to human warfare.
We may pass on to the second claim for war: that it is an essential factor in the social development of primitive human races. War has no part, though competition has a very large part, in what we call "Nature." But, when we come to primitive man the conditions are somewhat changed; men, unlike the lower animals, are able to form large communities—"tribes," as we call them—with common interests, and two primitive tribes can come into a competition which is acute to the point of warfare because being of the same, and not of two different, species, the conditions of life which they both demand are identical; they are impelled to fight for the possession of these conditions as animals of different species are not impelled to fight. We are often told that animals are more "moral" than human beings, and it is largely to the fact that, except under the immediate stress of hunger, they are better able to live in peace with each other, that the greater morality of animals is due. Yet, we have to recognise, this mischievous tendency to warfare, so often (though by no means always, and in the earliest stages probably never) found in primitive man, was bound up with his superior and progressive qualities. His intelligence, his quickness of sense, his muscular skill, his courage and endurance, his aptitude for discipline and for organisation—all of them qualities on which civilisation is based—were fostered by warfare. With warfare in primitive life was closely associated the still more fundamental art, older than humanity, of dancing. The dance was the training school for all the activities which man developed in a supreme degree—for
