“In the country of the mad, the sane man is crazy.”

“But crazy people never think they're crazy. You're sane just by the virtue of the question.”

“To be sane in a world of madman is in itself madness.”

“The only way to stay sane is to go a little crazy.”

“That crazy bastard may be the only sane one left.”

“When the whole world is crazy, it doesn't pay to be sane.”

“In a totally sane society, madness is the only freedom.”

“Madness is tonic and invigorating. It makes the sane more sane. The only ones who are unable to profit by it are the insane.”

“Orr would be crazy to fly more missions and sane if he didn't,
but if he was sane he had to fly them. If he flew them he was crazy and didn't have to; but if he didn't want to he was sane and had to. That's some catch, that catch-22.”

“If I am mad, it is mercy! May the gods pity the man who in his callousness can remain sane to the hideous end!”
