More often there's a compromise between ethics and expediency.

We should aim for our children to be good people, and to live ethical lives that manifest concern for others as well as for themselves.

We see things like reciprocity which are fairly central to our view of ethics. But if you're talking about a set of worked-out rules on what we are supposed to do then, yes, it is a human product.

I'm interested in the psychological exploration of human nature, and it just happens to come in the form of film-making.

I have no neighbours other than animals and Joshua Trees.

Learning, n. The kind of ignorance distinguishing the studious.
