Only if we understand, can we care. Only if we care, we will help. Only if we help, we shall be saved.

Even when it comes to things like wars over oil, which may seem like a whole different ball game, there are still comparisons one can draw: chimps fight for their territory; they fight for the resources within that territory, so it does relate in a way.

I believe that we have more capability than any other creature to control our biological inheritance - and we do so most of the time.

What you do makes a difference, and you have to decide what kind of difference you want to make.

I had a wonderful teacher about animal behavior - my dog Rusty. He taught me that animals have personalities, minds, and feelings.

Even in chimps there is true altruistic behaviour; behaviour that doesn't fit into the sociobiological model that says you either help a close relative and thereby your own genes, or you help somebody else now in return for their help in the future. When a very high-ranking male chimpanzee rescues a little orphan, saving his life, that kind of explanation doesn't work.

I don't have any idea of who or what God is. But I do believe in some great spiritual power. I feel it particularly when I’m out in nature. It’s just something that's bigger and stronger than what I am or what anybody is. I feel it. And it's enough for me.
