Sanity is the one unbelievable bore. One must be mad, slightly twisted - then one sees life from a new and entrancing angle.

One person's craziness is another person's reality.

Insanity is often the logic of an accurate mind overtasked. Good mental machinery ought to break its own wheels and levers, if anything is thrust among them suddenly which tends to stop them or reverse their motion. A weak mind does not accumulate force enough to hurt itself; stupidity often saves a man from going mad.

See what I mean? You gotta be crazy. Ain't no time to be sane.

One must be sane to think clearly, but one can think deeply and be quite insane.

The sole difference between myself and a madman is the fact that I am not mad!
