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.

The luckiest thing that ever happened to me was that my father didn't believe in God, and so he had no hang-ups about souls.

I wish there would be more movies about scientists.

Some think there is something wrong about enhancing people.

Today, the theory of evolution is an accepted fact for everyone but a fundamentalist minority, whose objections are based not on reasoning but on doctrinaire adherence to religious principles.

Ever since we achieved a breakthrough in the area of recombinant DNA in 1973, left-wing nuts and environmental kooks have been screaming that we will create some kind of Frankenstein bug or Andromeda Strain that will destroy us all.

One of the greatest gifts science has brought to the world is continuing elimination of the supernatural, and it was a lesson that my father passed on to me, that knowledge liberates mankind from superstition. We can live our lives without the constant fear that we have offended this or that deity who must be placated by incantation or sacrifice, or that we are at the mercy of devils or the Fates. With increasing knowledge, the intellectual darkness that surrounds us is illuminated and we learn more of the beauty and wonder of the natural world.
