It was morality that burned the books of the ancient sages, and morality that halted the free inquiry of the Golden Age and substituted for it the credulous imbecility of the Age of Faith. It was a fixed moral code and a fixed theology which robbed the human race of a thousand years by wasting them upon alchemy, heretic-burning , witchcraft and sacerdotalism.

The demagogue is one who preaches doctrines he knows to be untrue to men he knows to be idiots.

A man loses his sense of direction after four drinks; a woman loses hers after four kisses.

The wholly manly man lacks the wit necessary to give objective form to his soaring and secret dreams, and the wholly womanly woman is apt to be too cynical a creature to dream at all.

Hygiene is the corruption of medicine by morality.

No married woman ever trusts her husband absolutely, nor does she ever act as if she did trust him. Her utmost confidence is as wary as an American pickpocket's confidence that the policeman on the beat will stay bought.

I am never much interested in the effects of what I write....I seldom read with any attention the reviews of my...books. Two times out of three I know something about the reviewer, and in very few cases have I any respect for his judgments. Thus his praise, if he praises me, leaves me unmoved. I can't recall any review that has even influenced me in the slightest. I live in sort of a vacuum, and I suspect that most other writers do, too. It is hard to imagine one of the great ones paying any serious attention to contemporary opinion.
