I am personally not against keeping animals at zoos, as they serve a huge educational purpose, but treating them well and with respect seems the least we could do, and with 'we' I mean not just zoo staff, but most certainly also the public.

To endow animals with human emotions has long been a scientific taboo. But if we do not, we risk missing something fundamental, about both animals and us.

We, who think like animals living in small groups, must structure a global world. We believe in universal human rights and believe racism and war are wrong. On the other hand, it is our nature to be cooperative and loving almost exclusively with the members of the group to which we feel we belong.

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.

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

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.

If you want to design a successful human society you need to know what kind of animal we are. Are we a social animal or a selfish animal? Do we respond better when we're solitary or living in a group?
