I like to think 'The God Delusion' is a humorous book. I think, actually, it's full of laughs. And people who describe it as a polarizing book or as an aggressive book, it's just that very often they haven't read it.

You don't believe that the Earth is round only if you're an astronaut. You don't believe Napoleon existed only if you're a historian. You believe these things because they're facts, proved by evidence.

The Bishop goes on to the human eye, asking rhetorically, and with the implication that there is no answer, 'How could an organ so complex evolve?' This is not an argument, it is simply an affirmation of incredulity.

If it is solely an evolutionary convenience, there is really no such thing as good or evil.

It's a truly disgusting idea that the creator of the universe - capable of inventing the laws of physics and designing the evolutionary process - that this protégé of supernatural intellect couldn't think of a better way to forgive our sins than to have himself tortured to death.

I think the written word is probably the best medium of communication because you have time to reflect, you have time to choose your words, to get your sentences exactly right. Whereas when you're being interviewed, say, you have to talk on the fly, you have to improvise, you can change sentences around, and they're not exactly right.

No educated person believes the Adam and Eve myth nowadays, but it's surprising how many parents think that it's somehow fun to pass on this falsehood to their children...I would want to argue that the truth of evolution is more interesting and more poetic
