Now at the back of all this, of course, the real difference is religious. I only take this one case of what is called temperance for the sake of the wider philosophy that underlies it. When my young American friend talked of the next generation growing up without the desire for “alcohol,” he had at the back of his mind a certain idea. It is the idea which I have just seen expressed by another American in a high-brow article, in the words: “Evolution does not stand still. We are not finished. The world is not finished.” What it means is that the nature of man can be modified to suit the convenience of particular men; and this would certainly be very convenient. If the rich man wants the miners to live underground, he may really breed for it a new race as blind as bats and owls. If he finds it cheaper to run the schools and school inspections on Adamite principles, he can hope to produce Adamites not merely as a sect but as a species. And the same will be true of teetotalism or vegetarianism; nature, having evolved man who is an ale-drinking animal, may now evolve a super-man, or a sub-man, who shall be a water-drinking animal. Having risen from a monkey who eats nuts to a man who eats mutton, he may rise yet higher by eating nuts again. Thinking people, of course, know that all that is nonsense. They know there is no such constant flux of adaption. So far from saying that the evolution of man has not finished, they will point out that (as far as we know) it has not begun. In all the five thousand years of recorded history, and in all the prehistoric indications before it, there is not a shadow or suspicion of movement or change in the human biological type. Even evolution, let alone natural selection, is only a conjecture about things unknown, compared with the broad daylight of things known in all those thousands of years. The only difference is that evolution seems a probable conjecture, and natural selection is on the face of it an extravagantly improbable one. All this, which is obvious to thinking people, has at last become obvious even to the most unthinking; and _that_ is the meaning of the attack on Darwinism in America and the battle of Mr. Bryan against the Missing Link. The secret is out. The obscurantism of the professors is over. Those of us who have humbly hammered on this point from time to time suddenly find ourselves hammering on an open door. For these changes almost always come suddenly; which is alone enough to show that human history at least has never been merely an evolution. As Darwinism came with a rush, so Anti-Darwinism has come with a rush; and just as people who accepted evolution could not be held back from embracing natural selection, so it is likely enough that many, who now see reason to reject natural selection, will not be stopped in their course till they have also rejected evolution. They will merely have a vague but angry conviction that the professors have been kidding them, as they had before that the
