The Virtue of Nationalism, by Yoram Hazony. Falls into the “contrarian, but shouldn’t need to be contrarian” category. It makes good points, but I felt it was interior to my knowledge set.
Karl Ove Knausgaard, Spring, a comeback for Knausgaard.
Gabriel Said Reynolds, The Quran and the Bible: Text and Commentary. I won’t have the time soon to work through the thousand pages of this book, but it appears to be a major achievement and of very high quality. Here is the book’s home page. Here is a good piece by Reynolds on related topics.
Nick Polson and James Scott, AIQ: How People and Machines are Smarter Together, is a new and (believe it or not) original and very good take on this theme.
Heiner Rindermann, Cognitive Capitalism: Human Capital and Wellbeing of Nations perhaps covers too much ground, but is still a very useful 500 pp. plus survey of exactly what the title suggests.
Jan Assmann, The Invention of Religion: Faith and Covenant in the Book of Exodus. One of the best introductory works on the best and most important book ever written.
