Enough madness? Enough? And how do you measure madness? - The Joker

"Madness is the emergency exit. You can just step outside, and close the door on all those dreadful things that happened. You can lock them away…forever."
The Joker

You need a little bit of insanity to do great things.

[He]... watches the Joker rising from his wheelchair, the way a rabbit watches car headlights bearing down, unable to move a single, spotlit muscle. The madman's limbs appear to unlatch as though some psychotic god has chosen to give life to a complicated Swiss Army knife. The Joker's head rotates... the green lasers of his eyes target the keys at the big man's belt, and he shakes his head.

Gravity and sadness yank us down, and hope gives us a nudge to help one another get back up or to sit with the fallen on the ground, in the abyss, in solidarity.

Oh, don't take it so hard. I drove into this madness. Every woman needs a little madness in her life.

Madness is somewhere between chaos and having a dream.

Sometimes it’s only madness that makes us what we are.

All living things contain a measure of madness that moves them in strange, sometimes inexplicable ways.

You have everything but one thing: madness. A man needs a little madness or else - he never dares cut the rope and be free.

Gravity is a bitch until she's on your side.

There is madness in youth, but sometimes a god inspires it.

The more one approaches madness, the more one equally approaches the truth, and if one does not fall into the former, one must end up necessarily in the latter.

If there must be madness, something may be said for having it on a heroic scale
