Wild groups of chimpanzees attack their enemies like gangs. What they completely lack, precisely because of their strong territorial behavior, is a friendly relationship with their neighbors.

Most men probably wouldn't want to live the lives of bonobos. They're constantly clinging to their mothers' apron strings. They lack the ability to make decisions about their own fates, something that we and male chimpanzees practically consider our birthright.

If you look at national economies today, for example, the American economy, the European economy, the Indians, the Chinese, we're all tied together. If one of them sinks, the rest are going to sink with them and if one floats, the rest are lifted up. I find that very interesting.

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.

We justify the inequalities by saying some people are just better and smarter than others and the strong should survive and the poor can die off.

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?

You need to indoctrinate empathy out of people in order to arrive at extreme capitalist positions.
