If you are interested in positive psychology this book is well worth adding to your library as it takes such a different tack on the subject. As part of his university studies Haidt took courses in both philosophy (including ancient beliefs) and psychology. Before he became interested in positive psychology Haidt extensively studied the psychology of morality. His background strongly influences this book.
Haidt has combed the history of literature to discover a series of quotations that represent the major beliefs that were once held about the subject of how to achieve happiness. Haidt compares these beliefs to the modern findings of psychology. This approach takes the subject in new directions not previously covered by other authors. Chapter 7, for example, examines the belief that adversity, if it does not destroy you, makes you stronger. To give a little of the book away Haidt often finds that the historical beliefs were partly true but need to be modified in some way.
Haidt is uniquely qualified to discuss the benefits of religion in attaining happiness and some of the most interesting passages in the book revolve around psychological speculation on that subject. Could we be genetically programmed, through evolution, to share group beliefs? It is important to note that Haidt's book serves the function of pointing out new areas needing psychological studied rather than providing all the answers in the form of controlled experiment reports. Sometimes the evidence just isn't there, the evolution of religion being a case in point.
If I have one small criticism it is that Haidt does not seem to spend enough time on each subject to fully cement it in the mind of the reader. At only 243 pages this is a short book and may need to be read several times before the information 'sticks' to you. Haidt possibly wrote the book in this way because some of the material has been covered excellently in detail in other books such as Stefan Klein's <The Science of Happiness>.
Haidt integrates the tenets of positive psychology with the wisdom of various philosophical traditions to weave a practical guide to modern life. Any of the dozens of insights he provides could be game changers if applied thoughtfully. There are gems strewn about here that will delight the reader and serve as justification for multiple readings. I bought extra copies and have been giving them to friends--something I've never done before with other books that I have admired. Buy this book; if you are disappointed after having read even half of it, I'd be interested to know whether you have already reached enlightenment or are incapable of appreciating the concept of the well examined life. This is one of those few books that may change the way you live your life.
