Moral naturalism

David Brooks of the New York Times is on a roll. He has an interesting article today giving a quick overview of some recent research on morality.

Where does our sense of right and wrong come from? Most people think it is a gift from God, who revealed His laws and elevates us with His love. A smaller number think that we figure the rules out for ourselves, using our capacity to reason and choosing a philosophical system to live by.

Moral naturalists, on the other hand, believe that we have moral sentiments that have emerged from a long history of relationships. To learn about morality, you don’t rely upon revelation or metaphysics; you observe people as they live.

This week a group of moral naturalists gathered in Connecticut at a conference organized by the Edge Foundation. One of the participants, Marc Hauser of Harvard, began his career studying primates, and for moral naturalists the story of our morality begins back in the evolutionary past. It begins with the way insects, rats and monkeys learned to cooperate.

By the time humans came around, evolution had forged a pretty firm foundation for a moral sense. Jonathan Haidt of the University of Virginia argues that this moral sense is like our sense of taste. We have natural receptors that help us pick up sweetness and saltiness. In the same way, we have natural receptors that help us recognize fairness and cruelty. Just as a few universal tastes can grow into many different cuisines, a few moral senses can grow into many different moral cultures.

He raises some interesting points about the current limitations of moral naturalism (of which I’m a supporter by the way — it’s clear by looking at our closest relatives that  our sense of morality has an evolutionary basis:

They emphasize group cohesion over individual dissent. They emphasize the cooperative virtues, like empathy, over the competitive virtues, like the thirst for recognition and superiority. At this conference, they barely mentioned the yearning for transcendence and the sacred, which plays such a major role in every human society.

These strike me as valid objections, and as areas that moral naturalists should be exploring
