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.

Some people say, therefore, that violence and war are inevitable. I say rubbish: Our brains are fully capable of controlling instinctive behavior.

If we start with chimpanzees, they differ from us with the composition of the DNA by only just over one percent. So, as far as genetics go, we're almost identical. The composition of the blood, the immune system, the structure of the brain - almost identical.

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

To reconnect with nature is key if we want to save the planet.

One thing I had learned from watching chimpanzees with their infants is that having a child should be fun.

....I understood why those who had lived through war or economic disasters, and who had built for themselves a good life and a high standard of living, were rightly proud to be able to provide for their children those things which they themselves had not had. And why their children, inevitably, took those things for granted. It meant that new values and new expectations had crept into our societies along with new standards of living. Hence the materialistic and often greedy and selfish lifestyle of so many young people in the Western world, especially in the United States.
