As a scientist, I am hostile to fundamentalist religion because it actively debauches the scientific enterprise. It teaches us not to change our minds, and not to want to know exciting things that are available to be known. It subverts science and saps the intellect.

Most people understand that sexual lust has to do with propagating genes. Copulation in nature tends to lead to reproduction and so to more genetic copies. But in modern society, most copulations involve contraception, designed precisely to avoid reproduction. Altruism probably has origins like those of lust.

Science replaces private prejudice with public, verifiable evidence.

You can never be absolutely certain that anything doesn't exist. But you can show that it's unlikely.

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.

We have sexual lust even though we know perfectly well that, because we're using contraception, it is not going to result in the propagation of our genes. That doesn't matter, because the lust was built into our brains at a time when there was no contraception.

Charles Darwin made arguably the greatest discovery any human has ever made. He was a man of great persistence. He wasn't probably a natural genius, he worked very hard - even though he was an invalid. He was a great family man, a very nice man. I think he was admirable in all sorts of ways.
