I am not an enthusiast for diversity of opinion where facts are concerned.

I find that religion really does motivate people to do horrible things because they have this passionate faith in whatever their religion happens to be, and it teaches them that the other religion is the wrong one.

I can remember at the age of about six being fascinated by the planets and learning all about Mars and Venus and things.

To me, the right approach is to say we are profoundly ignorant of these matters. We need to work on them. But to suddenly say the answer is God - it's that that seems to me to close off the discussion.

We are digital archives of the African Pliocene, even of Devonian seas; walking repositories of wisdom out of the old days. You could spend a lifetime reading in this ancient library and die unsated by the wonder of it.

How any government could promote the Vardy academies in the North-East of England is absolutely beyond me. Tony Blair defends them on grounds of diversity, but it should be unthinkable in the 21st century to have a school whose head of science believes the world is less than 10,000 years old.

Some sort of belief in all-powerful supernatural beings is common, if not universal. A tendency to obey authority, perhaps especially in children, a tendency to believe what you're told, a tendency to fear your own death, a tendency to wish to see your loved ones who have died, to wish to see them again, a wish to understand where you came from, where the world came from, all these psychological predispositions, under the right cultural conditions, tend to lead to people believing in things for which there is no evidence.
