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.

I've argued that many of what philosophers call moral sentiments can be seen in other species. In chimpanzees and other animals, you see examples of sympathy, empathy, reciprocity, a willingness to follow social rules. Dogs are a good example of a species that have and obey social rules; that's why we like them so much, even though they're large carnivores.

If you ask anyone, what is morality based on? These are the two factors that always come out: One is reciprocity, … a sense of fairness, and the other one is empathy and compassion.

The primate laugh is given in playful contexts, and as such has a strong similarity to the human laugh.

I think we need to start thinking about grounding our moral systems in our biology.
