No excellent soul is exempt from a mixture of madness.

The great proof of madness is the disproportion of one's designs to one's means.

A man should not strive to eliminate his complexes, but to get into accord with them; they are legitimately what directs his conduct in the world.

Better mad with the rest of the world than wise alone.

You want to hear about insanity? I was found running naked through the jungles in Mexico. At the Mexico City airport, I decided I was in the middle of a movie and walked out on the wing on takeoff. My body... my liver... okay, my brain... went.

I may be crazy but it keeps me from going insane.

Insanity is hereditary. You get it from your children.

Insanity in individuals is something rare -- but in groups, parties, nations, and epochs it is the rule.

I became insane, with long intervals of horrible sanity.

Whom God wishes to destroy, he first makes mad.

All of us are crazy in one way or another.

The way it is now, the asylums can hold the sane people but if we tried to shut up the insane we would run out of building materials.
