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

There's a long tradition in Western thought that humans are not shackled by biology, whereas animals are pure instinct machines.

We need to separate the process of evolution - which is, indeed, a self-serving process - and the actual motivations of animals.

Our brains have been designed to blur the line between self and other. It is an ancient neural circuitry that marks every mammal, from mouse to elephant.

You should know as much as you can about the human species if you have a hand in designing human society.

Experiments with animals have long been handicapped by our anthropocentric attitude: We often test them in ways that work fine with humans but not so well with other species.
