Dogmatists have one advantage: they are poor listeners.

A chimpanzee who is really gearing up for a fight doesn't waste time with gestures but just goes ahead and attacks.

People want to work with somebody who feels shame, who worries about the perceptions of others. Dishonesty is something we don't like in others.

The role of inequity in society is grossly underestimated. Inequity is not good for your health, basically.

It wasn't God who introduced us to morality; rather, it was the other way around. God was put into place to help us live the way we felt we ought to.

It is not only visitors to the zoo who are fascinated but uneasy in the presence of chimpanzees; the same is true of scientists. The more they learn about these great apes, the deeper our identity crisis seems to become. The resemblance between humans and chimpanzees is not only external. If we look straight and deep into a chimpanzee’s eyes, an intelligent, self-assured personality looks back at us. If they are animals, what must we be?

Most exotic animals are not particularly interested in people, which makes it hard to provoke them. Human-rearing gets them used to and sometimes imprinted on humans, which makes them potentially dangerous.
