“Why, I can't help wondering, is God thought to need such ferocious defence? One might have supposed him amply capable of looking after himself.”

“A god who is capable of sending intelligible signals to millions of people simultaneously, and of receiving messages from all of them simultaneously, cannot be, whatever else he might be, simple. Such Bandwidth!”

“[I]sn't it sad to go to your grave without ever wondering why you were born? Who, with such a thought, would not spring from bed, eager to resume discovering the world and rejoicing to be part of it?”

“The feeling of awed wonder that science can give us is one of the highest experiences of which the human psyche is capable. It is a deep aesthetic passion to rank with the finest that music and poetry can deliver. It is truly one of the things that make life worth living and it does so, if anything, more effectively if it convinces us that the time we have for living is quite finite.”

“Many of us saw religion as harmless nonsense. Beliefs might lack all supporting evidence but, we thought, if people needed a crutch for consolation, where's the harm? September 11th changed all that.”

“There is no reason to regard God as immune fromconsideration along the spectrum of probabilities. And there iscertainly no reason to suppose that, just because God can be neitherproved nor disproved, his probability of existence is 50 per cent.”

“It would be intolerant if I advocated the banning of religion, but of course I never have. I merely give robust expression to views about the cosmos and morality with which you happen to disagree. You interpret that as ‘intolerance’ because of the weirdly privileged status of religion, which expects to get a free ride and not have to defend itself. If I wrote a book called The Socialist Delusion or The Monetarist Delusion, you would never use a word like intolerance. But The God Delusion sounds automatically intolerant. Why? What’s the difference? I have a (you might say fanatical) desire for people to use their own minds and make their own choices, based upon publicly available evidence. Religious fanatics want people to switch off their own minds, ignore the evidence, and blindly follow a holy book based upon private ‘revelation’. There is a huge difference.”
