I do not want to discuss evolution in such depth, however, only touch on it from my own perspective: from the moment when I stood on the Serengeti plains holding the fossilized bones of ancient creatures in my hands to the moment when, staring into the eyes of a chimpanzee, I saw a thinking, reasoning personality looking back. You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.

The Soul of Money is an inspired and utterly fascinating book. It will change the way you think about money. ... It is a book for everyone who would like to make the world a better place.

You have to really care about what you say. And if you don't, it will never come out quite right, unless you go into acting, in which case you have to act fast before you realize it is something which you do not believe in.

I have found that to love and be loved is the most empowering and exhilarating of all human emotions.

In Tanzania, the chimps are isolated in a very tiny patch of forest. I flew over it 13 years ago and realized that, basically, all the trees had gone, that people all around the park are struggling to survive. It became very clear that there was no way to protect the chimps while the people were in this dire circumstance.

I like some animals more than some people, some people more than some animals.

A chimp would never plan to pull another's nails out.
