The Five Moral Senses

University of Virginia moral psychologist Jonathan Haidt delivered an absolutely dynamite talk on new advances in his field last week. The video and a transcript have been posted by Edge.org, a loose consortium of very smart people run by John Brockman. Haidt whips us through centuries of moral thought, recent evolutionary psychology, and discloses which two papers every single psychology student should have to read. Through it all, he's funny, erudite, and understandable. Here, we excerpt a few paragraphs from his conclusion, in which Haidt tells us how to think about our moral minds:

I've been arguing for the last few years that we've got to expand our conception of the moral domain, that it includes multiple moral foundations, not just sugar and salt, and not just harm and fairness, but a lot more as well. So, with Craig Joseph and Jesse Graham and Brian Nosek, I've developed a theory called Moral Foundations Theory, which draws heavily on the anthropological insights of Richard Shweder...

That the five most important taste receptors of the moral mind are the following...care/harm, fairness/cheating, group loyalty and betrayal, authority and subversion, sanctity and degradation. And that moral systems are like cuisines that are constructed from local elements to please these receptors.

So, I'm proposing, we're proposing, that these are the five best candidates for being the taste receptors of the moral mind. They're not the only five. There's a lot more. So much of our evolutionary heritage, of our perceptual abilities, of our language ability, so much goes into giving us moral concerns, the moral judgments that we have. But I think this is a good starting point.
