I am not a madman or a nut.

The only difference between me and a madman is that I'm not mad.

There is only one difference between a madman and me. I am not mad.

There is only one difference between a madman and me. The madman thinks he is sane. I know I am mad.

What frightens us most in a madman is his sane conversation.

Possibly he knew, as he wrote this, that he was mad - because inside every madman sits a little sane man saying 'You're mad, you're mad.'

We must not contradict, but instruct him that contradicts us; for a madman is not cured by another running mad also.

The genius which runs to madness is no longer genius.

There is in every madman a misunderstood genius whose idea, shining in his head, frightened people, and for whom delirium was the only solution to the strangulation that life had prepared for him.
