..., spirituality and co-operation by the psychologist Jonathan Haidt. My economist self was particularly interested in his thoughts on free-riding. The rest of me was particularly interested in the discussion as a whole.
It's curious to reflect on the things that give meaning and purpose to our lives. On that note, I've often wondered whether the appeal of atheism would diminish if there were no believers to convince otherwise?
UPDATE: Haidt has just published a new book that is getting rave reviews.
