What can you do against the lunatic who is more intelligent than yourself, who gives your arguments a fair hearing and then simply persists in his lunacy?

We want a few mad people now. See where the sane ones have landed us!

Our society is run by insane people for insane objectives. I think we're being run by maniacs for maniacal ends and I think I'm liable to be put away as insane for expressing that. That's what's insane about it.

Madness is something rare in individuals -- but in groups, parties, peoples, ages it is the rule.

O, let me not be mad, not mad, sweet heaven! Keep me in temper. I would not be mad.

I have cultivated my hysteria with delight and terror. Now I suffer continually from vertigo, and today, 23rd of January, 1862, I have received a singular warning, I have felt the wind of the wing of madness pass over me.

No excellent soul is exempt from a mixture of madness.

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

Much Madness is divinest Sense -- to a discerning Eye -- much Sense -- the starkest Madness --

No great genius has ever existed without some touch of madness.
