The ‘Intermission’ is the best and most definitive chapter of the book. I took away an insight, here, and an important nuance: religion, and specifically Christianity, is not a physical thing. And as an historical idea, it shouldn’t be, and can’t be, parsed using the same tools that we use for, say, genetics.
The book is well written but not light. Diamond weaves geography, climate, religion, and politics into a complex whole as he steps through several cultures to examine in detail what drove them to virtual extinction.
Real nutrition is boring, and no one needs to buy a book to read about it. Eat mostly real food. Cook it yourself. Go heavy on plants and light on the meat. Dessert is fine. Watch your portions. Enjoy clean water. Exercise a little. Hug your kids.
But there is plenty of good stuff here. The book is thorough and addresses all areas of endeavor. I expected to read about food and leisure and a kind of lazy mindfulness. I did not expect to read about Slow cities, Slow education, or Slow sex
Oh. And he blames the Nazis on evolution, too.
