I don't like to compare myself to others. I just try to be the best I can be.

To isolate mental processes from their adaptive context is to misunderstand them completely.

I can dispense with all truth, but not with the search for truth.

The greatest risk is not taking one.

I remember my friend Johnny von Neumann used to say, 'with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.'
