But this dismal creed does not discourage those who believe that the impulse that produces evolution is creative. They have observed the simple fact that the will to do anything can and does, at a certain pitch of intensity set up by conviction of its necessity, create and organize new tissue to do it with. To them therefore mankind is by no means played out yet. If the weight lifter, under the trivial stimulus of an athletic competition, can 'put up a muscle,' it seems reasonable to believe that an equally earnest and convinced philosopher could 'put up a brain.' Both are directions of vitality to a certain end. Evolution shews us this direction of vitality doing all sorts of things: providing the centipede with a hundred legs, and ridding the fish of any legs at all; building lungs and arms for the land and gills and fins for the sea; enabling the mammal to gestate its young inside its body, and the fowl to incubate hers outside it; offering us, we may say, our choice of any sort of bodily contrivance to maintain our activity and increase our resources.
