What I am skeptical about is the idea that whatever wonderful revelation does come in the science of the future, it will turn out to be one of the particular historical religions that people happen to have dreamed up.

What are all of us but self-reproducing robots? We have been put together by our genes and what we do is roam the world looking for a way to sustain ourselves and ultimately produce another robot child.

It is immoral to brand children with religion. 'This is a Catholic child.' 'That is a Muslim child.' I want everyone to flinch when they hear such a phrase, just as they would if they heard, 'That is a Marxist child.'

You can make some inferences about a man's character if you know something about the conditions in which he has survived and prospered.

We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes. This is a truth which still fills me with astonishment.

The whole of technology depends on a scientific background, and of course technology can be used for evil purposes. You can't blame science for that.

Faith is the great cop-out, the great excuse to evade the need to think.
