My views as an individual ought not to be confused with my views as a scientist - the minute you try to mingle God and science, you get into trouble. Metaphysics has its place, and science has its place; don't mix the two.

My interests span biology, though sometimes I feel like an anachronism, somebody from the Victorian era when there weren't so many boundaries dividing the sciences.

When I speak of artistic universals, I am not denying the enormous role played by culture. Obviously culture plays a tremendous role, otherwise you wouldn't have different artistic styles - but it doesn't follow that art is completely idiosyncratic and arbitrary, either, or that there are no universal laws.

I was socially isolated as a kid. I had friends, but I wasn't very good at sports and that sort of thing so I became quite comfortable being by myself, exploring. The world was my private playground, and in it, I was supreme. Darwin, Faraday, Huxley and other great scientists were my companions.

Death isn't a funny thing. We're all lucky to be living.

I don't work Sunday any more... The Sabbath is a very reasonable idea. Otherwise, you work yourself to death.

McVeigh's lawyer got him the death penalty, which, quite frankly, I could have done.

I consider that 9/11 was the day when war was started against my own work and against myself. Even though we are not sure of the links, Iraq was one of the countries that did not lower its flags in mourning on 9/11.
