Anyone can make them cry, but it takes a genius to make them laugh.

True genius resides in the capacity for evaluation of uncertain, hazardous, and conflicting information.

I used to think I must be a genius, but nobody's noticed. I used to wonder whether I'm a genius or I'm not, which is it? I used to think, well, I can't be mad, because nobody's put me away, therefore, I'm a genius. A genius is a form of madness, and we're all that way, you know, and I used to be a bit coy about it, like my guitar playing.

A genius is a talented person who does his homework.

The promise of this life is imperiled by the very genius that has made it possible.

Genius is not inspired. Inspiration is perspiration.
