I begin with human psychology and then see what we can say about ethics.

If we don't have historical consciousness we can't really understand problems in all their dimensions, and if we can't understand problems than we can't find solutions.

We're good at noticing sudden movements of middle size objects in our immediate visual field, but what is out of sight is for us is largely out of mind.

Since for me moral demands necessarily flow from human psychology, I don't think we can be obliged to do something that we are not motivated in any way to do. In other words, I'm an "internalist" about morality.

In much of the world today there are no more chilling words than "I'm from the United States and I'm here to help you."

Our differences should not be exaggerated.

Ethics is prescriptive and can change behavior, but usually only at the margins.
