I am all for cultural diversity and would be willing to see each recognizable group value its cultural heritage. I am a New York patriot, for instance, and if I lived in Los Angeles, I would love to get together with other New York expatriates and sing "Give My Regards to Broadway".

There is a single light of science, and to brighten it anywhere is to brighten it everywhere.

I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be.

Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest.

There are no happy endings in history, only crisis points that pass.

I am not responsible for what other people think. I am responsible only for what I myself think, and I know what that is. No idea I've ever come up with has ever struck me as a divine revelation. Nothing I have ever observed leads me to think there is a God watching over me.

I don't believe in personal immortality; the only way I expect to have some version of such a thing is through my books.
