There are an awful lot of scientists today who believe that before very long we shall have unraveled all the secrets of the universe. There will be no puzzles anymore. To me, it'd be really, really tragic because I think one of the most exciting things is this feeling of mystery, feeling of awe, the feeling of looking at a little live thing and being amazed by it and how it has emerged through these hundreds of years of evolution and there it is and it is perfect and why.

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.

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.

When I go back to Gombe it's to be in that timeless world where it's soft and where life is entwined and you actually see the pattern of nature. I always feel this great spiritual power which I believe is around.

I just have this absolute belief that humans are moving away from cruelty and destruction towards a time when we can truly live in harmony with nature. When we understand that there is a spiritual power around us from which we can draw strength. That is where I believe human destiny ultimately is taking us. I just hope we have time.

You aren't going to save the world on your own. But you might inspire a generation of kids to save it for all of us. You would be amazed at what inspired children can do.

If you look into their [chimpanzees] eyes, you know you're looking into a thinking mind. They teach us that we are not the only beings with personalities, minds capable of rational thought, altruism and a sense of humor. That leads to new respect for other animals, respect for the environment and respect for all life.
