I couldn't claim that I was smarter than sixty-five other guys--but the average of sixty-five other guys, certainly!

People may come along and argue philosophically that they like one better than another; but we have learned from much experience that all philosophical intuitions about what nature is going to do fail.

Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it

I don't believe I can really do without teaching. The reason is, I have to have something so that when I don't have any ideas and I'm not getting anywhere, I can say to myself, "At least I'm living; at least I'm doing something. I'm making some contribution." It's just psychological.

The truth always turns out to be simpler than you thought.

I'd hate to die twice. It's so boring.

If a guy tells me the probability of failure is 1 in 100,000, I know he's full of crap.
