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

Surrealism had a great effect on me because then I realised that the imagery in my mind wasn't insanity. Surrealism to me is reality.

Madness is not a consequence of uncertainty but of certainty.

What can everyone do? Praise and blame. This is human virtue, this is human madness.

Almost everyone who has had an idea that's somewhat revolutionary or wildly successful was first told they're insane.
