The question of whether there exists a supernatural creator, a God, is one of the most important that we have to answer. I think that it is a scientific question. My answer is no.

Do not indoctrinate your children. Teach them how to think for themselves, how to evaluate evidence, and how to disagree with you.

Faith is belief without evidence and reason; coincidentally that's also the definition of delusion.

Such delusions of grandeur to think that a God with a hundred billion galaxies on his mind would give a tuppenny damn who you sleep with, or indeed whether you believe in him.

Very few people realize how dangerous the indoor environment can be to long term health.

The day we get comfortable with our lives is the day we sacrifice adventure.

At such times one sees everything and remembers it all. I know from personal experience. I wish I did not.

I'd like to decide who comes here. I'd like to be the admissions director of New York.

I always find a couple of hecklers... I'll kinda look at them, stare at 'em, and let them know I can't be stopped.

I just did one movie and there was no career for me, anyway.

When you start out in a team, you have to get the teamwork going and then you get something back.

I'm inspired by almost every artist I come across.

Hawaii is not a state of mind, but a state of grace.

I was unbelievably lucky.
