Breathtaking sweep across time and geography, flying along on the coat-tails of a theory that is so intuitively acceptable that it almost makes you say 'duh'. A society's institutions, extractive (bad) or inclusive (good) explain the wealth of the society and the health and happiness of the common man (and, if you are really lucky, woman). I hated history at school because it didn't explain: just one damn thing after another. This does, right up to the end where they use their theory to predict the future success of current societies. It explains why 'state building' (e.g. in Afgahanistan) is such a challenge. The UK (a pioneer in modern state building) got properly started on the process in 1215, brought in universal education in about 1890 and gave women the vote in 1928. Mind expanding book.
...but they probably will not even try, which is the pity with this type of book. Sam Harris is thoughtful, clever, funny and scary. It might seem expensive for only 1 hour 56 mins - but I think you'll want to listen to it twice.
I always feel that book's read by the author are far better to listen to and this book illustrates the point perfectly. Haidt is open, honest, informative and passionate about his chosen field of moral psychology. Throughout the book he is unbiased and remains remarkably dispassionate with regards to a variety of moral, social and political views, thus making this book thoroughly educational and informative whilst allowing you to make up your own mind and opinions. I would certainly recommend this to someone who is interested in this field, I have listened to it twice so far and i'm still not bored of it.
