I think the psychology of Morality is fascinating, and this is the area that Jonathan Haidt specialises in. Haidt's previous book, The Happiness hypothesis made a substantial addition to the chances of its readers achieving happiness, and was a fantastic contribution to well being, IMHO, and this latest offering of his is no less significant, I think.
In this book, Haidt attempts to elucidate the prejudices which are the most difficult for us to define and diminish- those which make our communities divided, which polarise us and cause us to misunderstand other groups and individuals who differ in their political or religious affiliations.
A very ambitious program, and it makes for a slightly denser read than the Happiness Hypothesis, but then it makes a more major contribution to the public dialogue of our societies. I think this is an important and fascinating book, as well as a potentially transformative and influential one. If we read carefully and are able to put aside our most closely held prejudices and take the points that he makes, this book has the potential to unite us and bed us down in our own communities more effectively than we ever have been before. It is a major contribution to our understanding of our own needs and the ties which bind and blind us, and it offers us a way forward out of the political impasse towards which both US and Australian politics is heading, and an insight into the goodness of those on the other side of the political and religious divide to ourselves.
