Fish don't know much about water, and people didn't know much about air.

People don't realize that molecules themselves are somewhat hypothetical, and that their interactions are more so, and that the biological reactions are even more so.

I love a microphone and a big crowd; I'm an entertainer, I guess.

If reincarnation is a useful biological idea it is certain that somewhere in the universe it will happen.

Sometimes in the morning, when it's a good surf, I go out there, and I don't feel like it's a bad world.

And all I knew about drugs was what I read in magazines like Time and Life. I learned that marijuana was a dangerous addictive drug and that I should stay away from it.

I like writing about biology, not doing it.
