Now, I ask, what is the difference which takes place when the monkey gradually loses his tail and sets up a superior brain? Is it properly to be described as a development or improvement of the "cosmic process," or as the beginning of a prolonged contest against it? In the first place, so far as man becomes a reasonable being, capable of foresight and of the adoption of means to ends, he recognises the nature of these tacit alliances. He believes it to be his interest not to exterminate everything, but to exterminate those species alone whose existence is incompatible with his own. The wolf eats every sheep that he comes across as long as his appetite lasts. If there are too many wolves, the process is checked by the starvation of the supernumerary eaters. Man can maintain just as many sheep as he wants, and may also proportion the numbers of his own species to the possibilities of future supply. Many of the lower species thus become subordinate parts of the social organism--that is to say, of the new equilibrium which has been established. There is so far a reciprocal advantage. The sheep that is preserved with a view to mutton gets the advantage, though he is not kept with a view to his own advantage. Of all arguments for vegetarianism, none is so weak as the argument from humanity. The pig has a stronger interest than any one in the demand for bacon. If all the world were Jewish, there would be no pigs at all. He has to pay for his privileges by an early death; but he makes a good bargain of it. He dies young, and, though we can hardly infer the "love of the gods," we must admit that he gets a superior race of beings to attend to his comforts, moved by the strongest possible interest in his health and vigour, and induced by its own needs, perhaps, to make him a little too fat for comfort, but certainly also to see that he has a good sty, and plenty to eat every day of his life. Other races, again, are extirpated as "ruthlessly" as in the merely instinctive struggle for existence. We get rid of wolves and snakes as well as we can, and more systematically than can be done by their animal competitors. The process does not necessarily involve cruelty, and certainly does not involve a diminution of the total of happiness. The struggle for existence means the substitution of a new system of equilibrium, in which one of the old discords has been removed, and the survivors live in greater harmony. If the wolf is extirpated as an internecine enemy, it is that there may be more sheep when sheep have become our allies and the objects of our earthly providence. The result may be, perhaps I might say must be, a state in which, on the whole, there is a greater amount of life supported on the planet; and therefore, as those will think who are not pessimists, a decided gain on the balance. At any rate, the difference so far is that the condition which was in all cases necessary, is now consciously recognised as necessary; and that we
