Every man of genius sees the world at a different angle from his fellows, and there is his tragedy.

The omnipresent process of sex, as it is woven into the whole texture of our man's or woman's body, is the pattern of all the process of our life.

It has always been difficult for Man to realize that his life is all an art. It has been more difficult to conceive it so than to act it so. For that is always how he has more or less acted it.

The place where optimism most flourishes is the lunatic asylum.

Of woman as a real human being, with sexual needs and sexual responsibilities, morality has often known nothing.

Had there been a Lunatic Asylum in the suburbs of Jerusalem, Jesus Christ would infallibly have been shut up in it at the outset of his public career. That interview with Satan on a pinnacle of the Temple would alone have damned him, and everything that happened after could have confirmed the diagnosis. The whole religious complexion of the modern world is due to the absence from Jerusalem of a Lunatic Asylum.

On the threshold of the moral world we meet the idea of Freedom, 'one of the weightiest concepts man has ever formed,' once a dogma, in the course of time a hypothesis, now in the eyes of many a fiction, yet we cannot do without it, even although we may be firmly convinced that our acts are determined by laws that cannot be broken.
