an abominable tradition that the man who hesitates to be as cruel as Circumstantial Selection itself is a traitor to science. For Weismann’s experiment upon the mice was a mere joke compared to the atrocities committed by other Darwinians in their attempts to prove that mutilations could not be transmitted. No doubt the worst of these experiments were not really experiments at all, but cruelties committed by cruel men who were attracted to the laboratory by the fact that it was a secret refuge left by law and public superstition for the amateur of passionate torture. But there is no reason to suspect Weismann of Sadism. Cutting off the tails of several generations of mice is not voluptuous enough to tempt a scientific Nero. It was a mere piece of one-eyedness; and it was Darwin who put out Weismann’s humane and sensible eye. He blinded many another eye and paralyzed many another will also. Ever since he set up Circumstantial Selection as the creator and ruler of the universe, the scientific world has been the very citadel of stupidity and cruelty. Fearful as the tribal god of the Hebrews was, nobody ever shuddered as they passed even his meanest and narrowest Little Bethel or his proudest war-consecrating cathedral as we shudder now when we pass a physiological laboratory. If we dreaded and mistrusted the priest, we could at least keep him out of the house; but what of the modern Darwinist surgeon whom we dread and mistrust ten times more, but into whose hands we must all give ourselves from time to time? Miserably as religion had been debased, it did at least still proclaim that our relation to one another was that of a fellowship in which we were all equal and members one of another before the judgment-seat of our common father. Darwinism proclaimed that our true relation is that of competitors and combatants in a struggle for mere survival, and that every act of pity or loyalty to the old fellowship is a vain and mischievous attempt to lessen the severity of the struggle and preserve inferior varieties from the efforts of Nature to weed them out. Even in Socialist Societies which existed solely to substitute the law of fellowship for the law of competition, and the method of providence and wisdom for the method of rushing violently down a steep place into the sea, I found myself regarded as a blasphemer and an ignorant sentimentalist because whenever the Neo-Darwinian doctrine was preached there I made no attempt to conceal my intellectual contempt for its blind coarseness and shallow logic, or my natural abhorrence of its sickening inhumanity.
