“To whatever degree he may have desacralized the world, the man who has made his choice in favor of a profane life never succeeds in completely doing away with religious behavior.”

“Do what he will, he [the profane man] is an inheritor. He cannot utterly abolish his past, since he himself is a product of his past. He forms himself by a series of denials and refusals, but he continues to be haunted by the realities that he has refused and denied. To acquire a world of his own, he has desacralized the world in which his ancestors lived; but to do so he has been obliged to adopt an earlier type of behavior, and that behavior is still emotionally present in him, in one form or another, ready to be reactualized in his deepest being. ”

“He was what men called a religious man, which in his case meant he was a superstitious man. There was never a man less Christian; there was never one who made a greater show of piety.”

“My choice of Muhammad to lead the list of the world's most influential persons may surprise some readers and may be questioned by others, but he was the only man in history who was supremely successful on both the religious and secular level.”

“Do you not know that there comes a midnight hour when every one has to throw off his mask? Do you believe that life will always let itself be mocked? Do you think you can slip away a little before midnight in order to avoid this? Or are you not terrified by it? I have seen men in real life who so long deceived others that at last their true nature could not reveal itself;... In every man there is something which to a certain degree prevents him from becoming perfectly transparent to himself; and this may be the case in so high a degree, he may be so inexplicably woven into relationships of life which extend far beyond himself that he almost cannot reveal himself. But he who cannot reveal himself cannot love, and he who cannot love is the most unhappy man of all.”

“Choice of attention--to pay attention to this and ignore that--is to the inner life what choice of action is to the outer. In both cases, a man is responsible for his choice and must accept the consequences, whatever they may be.”
