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

I see that within each human being there are two extremes: there's the loving, the passionate, altruistic side that has evolved with us, and then there's the violent, brutal side that has evolved with us. The question for each individual is: which side is going to come out on top?

I don't care two hoots about civilization. I want to wander in the wild.

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

Chimps are very quick to have a sudden fight or aggressive episode, but they're equally as good at reconciliation.

Empathy is really important.. Only when our clever brain and our human heart work together in harmony can we achieve our full potential.
