Chapter 2 was very, very good. Worth the whole book alone. It begins with by questioning "why did Rousseau wrote about inequality if 100 years before no one in western culture cared about it"? Then he goes to show how the themes of liberty and social equality came from Canadian First Nations criticism of western culture. It is very well argued, solid and mind-blowing.
Sometimes the book gets too much into petty fights. I didn't like its takes on Yuval Harari's "Sapiens" or Jared Diamond's "Guns, Germs and Steel". But that's a matter of my personal taste.
