This is an outstanding program & conversation. I read Haidt's The Happiness Hypothesis a few years ago and found it very persuasive. Now with his new book, The Righteous Mind, I think that I'm going to find him an even more important thinker. Moyers, as usual, does an outstanding job of engaging his guest in elucidating the guest's viewpoint. And this case, it's especially important and useful because Haidt argues that political conservatives in the U.S. understand more about moral psychology than do liberals. Overall, elections since the 1980's have born this out. Haidt adds a great deal of social science sophistication to understanding what's going on (and wrong) in our world today.
Moyers & Haidt touch on a number of topics: moral areas of concern (Haidt identifies five), reason & argumentation (Haidt seems to argue for the Sperber-Mercier view), sacralization of issues, and various other topics. There's a transcript @ the site, although I chose to listen, as Moyers usually carries on an enlightening conversation, and it's refreshing to experience it done well.
