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

Although elephants are far more distantly related to us than the great apes, they seem to have evolved similar social and cognitive capacities.

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.

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

We are by far the most contradictory of all primates. An animal with this much internal conflict has never lived on this earth.

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

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