An intelligent hell would be better than a stupid paradise.

I’ll drive down the street, and I’ll practice improv. I will sit there at a red light and see two guys talking to each other, and I will just start playing both characters. I can’t hear them, but I can see their mouths moving, so I’ll just put words in their mouths.

Intelligence alone is not nearly enough when it comes to acting wisely.

Intelligence is not quite as important as I thought it was, and it takes many different forms.

Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius – and a lot of courage – to move in the opposite direction.

The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him.
