4/5 super duper relevant. Why do wars happen in the first place, why did the US just attack venezuela? This book offers answers and postulates. The authors even even observed Prole Drift, the phenomenon where a poor, unfortunate majority influences the wealthy minority. How they dress, speak, what trends are hot, music, etiquette. etc.
They describe the past as a celestial city with the brightest minds in all fields living in it. It is neutral, so is science. Humanity has been progressing. Light and Dark.
This book is very much a product of the 1960s and you can feel it on every page. It offers some genuinely interesting observations about centuries of history, but they come filtered through a sexist and racist lens that’s hard to ignore.
