Real life seeks the gentle slopes at the back of Mount Improbable, while creationists are blind to all but the daunting precipice at the front.

Our leaders have described the recent atrocity with the customary cliche: mindless cowardice. Mindless may be a suitable word for the vandalising of a telephone box. It is not helpful for understanding what hit New York on September 11. Those people were not mindless and they were certainly not cowards. On the contrary, they had sufficiently effective minds braced with an insane courage, and it would pay us mightily to understand where that courage came from. It came from religion.

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

Evolution is a very, very important idea. It is the explanation for all of life - a stunningly simple, yet powerful explanation. If you think about it, before Darwin, we hadn't the foggiest idea of how we came into being. Now we do. It's still such an exciting idea that it is well worth everybody understanding it.

There's a natural tendency for children to, in some sense, inherit the cultural values of their parents. I'm not against that, that's fine, that's wonderful. What I am against is labelling. Nobody ever labels a child a cricketer because his father is a cricketer, but they do label a child a Catholic because his parents are Catholic. I think it's more or less unique. Nobody ever labels a child a socialist or a conservative or a liberal because that's what their parents are.

Not only is science corrosive to religion, but religion is corrosive to science. It teaches people to be satisfied with trivial non-explanations and blinds them to the wonderful real explanations that we have within our grasp.

I think that there are good things that happen and bad things that happen.
