This is an excellent book about evolutionary psychology. It makes a convincing case that morality is an evolved feature of humanity and that there are psychological reasons, for humans as individuals and as a collective, for beliefs and judgements, that call into question the idea of righteousness.

It is extremely well written and laid out, with summaries at the end of each chapter. The author is, I imagine, a brilliant teacher and academic. Very thought provoking, with some practical suggestions for how we break out of the polarisation we are seeing in public discourse in so many places. The author’s focus is on the USA, which is good, as the bifurcation of the political scene there is as striking as anywhere.

First class.
