Man is an evasive beast, given to cultivating strange notions about himself. He is humiliated by his simian ancestry, and tries to deny his animal nature, to persuade himself that he is not limited by its weaknesses nor concerned in its fate. And this impulse may be harmless, when it is genuine. But what are we to say when we see the formulas of heroic self-deception made use of by unheroic self-indulgence? What are we to say when we see asceticism preached to the poor by fat and comfortable retainers of the rich? What are we to say when we see idealism become hypocrisy, and the moral and spiritual heritage of mankind twisted to the knavish purposes of class-cruelty and greed? What I say is — Bootstrap-lifting!
