“An atheist is someone who is certain that God doesn't exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence.”

“An atheist doesn't have to be someone who thinks he has a proof that there can't be a god. He only has to be someone who believes that the evidence on the God question is at a similar level to the evidence on the werewolf question.”

“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.”

“Atheists don’t hate fairies, leprechauns, or unicorns because they don’t exist. It is impossible to hate something that doesn't exist. Atheists — like the painting experts hated the painter — hate God because He does exist.”

“He who denies the existence of God, has some reason for wishing that God did not exist.”

“I am an atheist, out and out. It took me a long time to say it. I've been an atheist for years and years, but somehow I felt it was intellectually unrespectable to say one was an atheist, because it assumed knowledge that one didn't have. Somehow, it was better to say one was a humanist or an agnostic. I finally decided that I'm a creature of emotion as well as of reason. Emotionally, I am an atheist. I don't have the evidence to prove that God doesn't exist, but I so strongly suspect he doesn't that I don't want to waste my time.”
