“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.”

“Show me a cultural relativist at 30,000 feet and I'll show you a hypocrite ... If you are flying to an international congress of anthropologists or literary critics, the reason you will probably get there - the reason you don't plummet into a ploughed field - is that a lot of Western scientifically trained engineers have got their sum right.”

“It is often said, mainly by the 'no-contests', that although there is no positive evidence for the existence of God, nor is there evidence against his existence. So it is best to keep an open mind and be agnostic. At first sight that seems an unassailable position, at least in the weak sense of Pascal's wager. But on second thoughts it seems a cop-out, because the same could be said of Father Christmas and tooth fairies. There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?”

“Do you really mean to tell me the only reason you try to be good is to gain God's approval and reward, or to avoid his disapproval and punishment? That's not morality, that's just sucking up, apple-polishing, looking over your shoulder at the great surveillance camera in the sky, or the still small wiretap inside your head, monitoring your every move, even your every base though.”

“Evolution could so easily be disproved if just a single fossil turned up in the wrong date order. Evolution has passed this test with flying colours.”

“We are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.”

“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.”
