“I believe this is so and I'm prepared to vouch for it, because it seems to me that the meaning of man's life consists in proving to himself every minute that he's a man and not a piano key. And man will keep proving it and paying for it with his own skin; he will turn into a troglodyte if need be. And, since this is so, I cannot help rejoicing that things are still the way they are and that, for the time being, nobody knows worth a damn what determines our desires.”

“Every man is a damn fool for at least five minutes every day; wisdom consists in not exceeding the limit.”

“Man is afraid of prison although he himself consists of cells.”
