"Evolution can produce a workman who wants no more space than a snail, and no more light than an owl. The employer need not mind sending a Kaffir to work underground; he will soon become an underground animal, like a mole. He need not mind sending a diver to hold his breath in the deep seas; he will soon be a deep-sea animal. Men need not trouble to alter conditions, conditions will so soon alter men. The head can be beaten small enough to fit the hat. Do not knock the fetters off the slave; knock the slave until he forgets the fetters. To all this plausible modern argument for oppression, the only adequate answer is, that there is a permanent human ideal that must not be either confused or destroyed. The most important man on earth is the perfect man who is not there. The Christian religion has specially uttered the ultimate sanity of Man, says Scripture, who shall judge the incarnate and human truth. Our lives and laws are not judged by divine superiority, but simply by human perfection. It is man, says Aristotle, who is the measure. It is the Son of Man, says Scripture, who shall judge the quick and the dead."
