Jonathon Haidt is a terrifically productive thinker about psychology. This is book is a credo and a guide book to your own happiness via an accomplished romp through the psychological literature which Haidt uses to explore the truths of ancient religion. I'm surprised it's not a wild best seller, but I think I know why - it doesn't have an singular and catchy formula for your salvation which you can learn in your lunchtime and hear about ad nauseam on late night TV infomercials. Just well written, well thought out commentary on the formula for a happy and fulfilled life distilled from the psychological literature.
