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?

I think by the age of about nine I recognized that there were a lot of different religions, and it was an accident I happened to be born into one of them. If I had been born somewhere else, I would have had a different one. Which is a pretty good lesson, actually. Everyone should learn that.

Along with William Shakespeare and Isaac Newton, Charles Darwin is Britain's greatest gift to the world. He was our greatest thinker.

A retaliator behaves like a hawk when he is attacked by a hawk, and like a dove when he meets a dove. When he meets another retaliator he plays like a dove. A retaliator is a conditional strategist. His behaviour depends on the behaviour of his opponent.

Book critics or theatre critics can be derisively negative and gain delighted praise for the trenchant with of their review. But in criticisms of religion even clarity ceases to be a virtue and sounds like aggressive hostility. A politician may attack an opponent scathingly across the floor of the House and earn plaudits for his robust pugnacity. But let a soberly reasoning critic of religion employ what would in other contexts sound merely direct or forthright, and it will be described as a 'rant'.

[Richard Leakey is] a robust hero of a man, who actually lives up to the cliché, “a big man in every sense of the word.” Like other big men he is loved by many, feared by some, and not over-preoccupied with the judgments of any.

It is fashionable to wax apocalyptic about the threat to humanity posed by the AIDS virus, "mad cow" disease, and many others, but I think a case can be made that faith is one of the world's great evils, comparable to the smallpox virus but harder to eradicate.
