You can't imagine how gratifying it is to have a reader come up to you and say, 'You changed my life.'

Or why it is acceptable to train fast runners and high jumpers but not to breed them. I can think of some answers, and they are good ones, which would probably end up persuading me. But hasn't the time come when we should stop being frightened even to put the question?

We are survival machines – robot vehicles blindly programmed to preserve the selfish molecules known as genes. This is a truth which still fills me with astonishment.

I think that [Paul] Bloom's approach - and others who take it - is not so much that there is a precise genetic basis to faith. But there is a genetic basis to a psychological predisposition that manifests itself as faith and religion under the right conditions.

I detest 'Jingle Bells,' 'White Christmas,' 'Rudolph the Red Nosed Reindeer,' and the obscene spending bonanza that nowadays seems to occupy not just December, but November and much of October, too.

That was unfortunate. I should have compared religion with religion and compared Islam not with Trinity College but with Jews, because the number of Jews who have won Nobel Prizes is phenomenally high.

An atheist is just somebody who feels about Yahweh the way any decent Christian feels about Thor or Baal or the golden calf. We are all atheists about most of the gods that humanity has ever believed in. Some of us just go one god further.
