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

The thinking is that we started evolving language not by speaking but by gesturing.

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.

The hamadryas baboon is a harem holder where one male mates with multiple females.

There is little evidence that other animals judge the appropriateness of actions that do not directly affect themselves.

Chimpanzees, typically, kiss and embrace after fights. They first make eye contact from a distance to see the mood of the others. Then they approach and kiss and embrace.

If I were God, I'd work on the reach of empathy.
