Religion is not merely the opium of the masses, it's the cyanide.

That the world is in a bad shape is undeniable, but there is not the faintest reason in history to suppose that Christianity offers a way out.

Millions long for immortality who don't know what to do on a rainy Sunday afternoon.

My mother was Southern Irish, and I was brought up as a devout Catholic. In fact, at one point I thought I'd become a priest, but I'd have made an appalling priest anyway... At 16, I asked all these monks some serious questions and they didn't come up with the answers, and I just decided I didn't believe in God.

I do not believe in the creed professed by the Jewish Church, by the Roman Church, by the Greek Church, by the Turkish (Muslim) Church, by the Protestant Church, nor by any Church that I know of. My own mind is my own Church.

If you want to get together in any exclusive situation and have people love you, fine - but to hang all this desperate sociology on the idea of The Cloud-Guy who has The Big Book, who knows if you've been bad or good - and CARES about any of it - to hang it all on that, folks, is the chimpanzee part of the brain working.

Existentialism isn't so atheistic that it wears itself out showing that God doesn't exist. Rather, it declares that even if God did exist, that would change nothing.

A man's ethical behavior should be based effectually on sympathy, education, and social ties and needs; no religious basis is necessary. Man would indeed be in a poor way if he had to be restrained by fear of punishment and hope of reward after death.

To assert that the earth revolves around the sun is as erroneous as to claim that Jesus was not born of a virgin.

Suppose we've chosen the wrong god. Every time we go to church we're just making him madder and madder.
