I am an atheist, out and out. It took me a long time to say it.

Since emotions are few and reasons are many (said the robot Giscard) the behavior of a crowd can be more easily predicted than the behavior of one person.

Creationists make it sound as though a 'theory' is something you dreamt up after being drunk all night.

I want to be a human being, nothing more and nothing less. ... I don't suppose we can ever stop hating each other, but why encourage that by keeping the old labels with their ready-made history of millennial hate?

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.

The energy requirements for interstellar travel are so great that it is inconceivable to me that any creatures piloting their ships across the vast depths of space would do so only in order to play games with us over a period of decades. If they want to make contact, they would make contact; if not, they would save their energy and go elsewhere.

Intelligence is a valuable thing, but it is not usually the key to survival. Sheer fecundity ... usually counts. The intelligent gorilla doesn't do as well as the less intelligent but more-fecund rat, which doesn't do as well as the still-less-intelligent but still-more-fecund cockroach, which doesn't do as well as the minimally-intelligent but maximally-fecund bacterium.
