I would challenge the statement that my scientific instincts are any less rigorous than [Richard Dawkins]. The difference is that my presumption of the possibility of God and therefore the supernatural is not zero, and yours is.

The odd thing about tradition is, the longer it's been going, the more people seem to take it seriously - as though sheer passage of time makes something which to begin with was just made up, turns it into what people believe as a fact.

Let us try to teach generosity and altruism, because we are born selfish. Let us understand what our own selfish genes are up to, because we may then at least have the chance to upset their designs, something that no other species has ever aspired to do.

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.

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.

The so-called sophisticated theologians, especially ones who are very nice, like Rowan Williams and Jonathan Sacks, you sometimes don't quite know where you are with them. You feel that when you attack them, you're attacking a wet sponge.

Bereavement is terrible, of course. And when somebody you love dies, it's a time for reflection, a time for memory, a time for regret.
