I think anything is better than war. The extent to which one can negotiate with fanatics, I have no idea. I don't know.

What makes us human, I think, is an ability to ask questions, a consequence of our sophisticated spoken language.

I think I'd like to be remembered as someone who really helped people to have a little humility and realize that we are part of the animal kingdom not separated from it.

I don't even think of chimps as animals. I think of them as beings.

I don't think anybody has the right to a huge family. There's already more people on the planet than our natural resources can even support, and if everybody were to have a high standard of living, we need three or four or five new planets to provide the resources. And this cannot be, so something has to change.

I don't think that faith, whatever you're being faithful about, really can be scientifically explained. And I don't want to explain this whole life business through truth, science. There's so much mystery. There's so much awe.

My mother always taught us that if people don't agree with you, the important thing is to listen to them. But if you've listened to them carefully and you still think that you're right, then you must have the courage of your convictions.

I think we're still in a muddle with our language, because once you get words and a spoken language it gets harder to communicate.

We find animals doing things that we, in our arrogance, used to think was "just human".
