I recently went to my staircase at Clare College, Cambridge and there were women there! There have been a lot of convincing studies recently about the loss of productivity in the Western male. It may be that entertainment culture now is so engaging that it keeps people satisfied. We didn't have that. Science was much more fun than listening to the radio. When you are 16 or 17 and in that inherently semi-lonely period when you are deciding whether to be an intellectual, many now don't bother.

I don't think we are here for anything. We're just products of evolution. You can say, "Gee, your life must be pretty bleak if you don't think there's a purpose." But I'm anticipating a good lunch.

Whenever you interview fat people, you feel bad, because you know you're not going to hire them.

We're not all equal, it's simply not true. That isn't science.

At lunch Francis [Crick] winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.

I'm basically a libertarian. I don't want to restrict anyone from doing anything unless it's going to harm me. I don't want [to] pass a law stopping someone from smoking. It's just too dangerous. You lose the concept of a free society. Since we are genetically so diverse and our brains are so different, we're going to have different aspirations.

There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so.
