there have been too many events in my life, and in the lives of my friends, which have defied any kind of scientific explanation. Science does not have appropriate tools for the dissection of the spirit.

Studying chimps, I came to the conclusion that being evil is something that only humans are capable of. A chimp would never plan to pull another's nails out. The chimps' way of aggression is quick and brutal. I compare them to gang attacks.

You better not mess with chimps. They are much stronger than humans.

Chimps act the way they feel unless they are afraid of reprisal if they do so. But that doesn't apply to humans.

Each one of us matters, has a role to play, and makes a difference. Each one of us must take responsibility for our own lives, and above all, show respect and love for living things around us, especially each other.

Well, in some ways we're not successful at all. We're destroying our home. That's not a bit successful.

Animals have personalities and minds and emotions.
