In my opinion, the book is about 1) How geographical location and natural factors (accidental agriculture etc.) resulted in some part of the humanity accumulate certain knowledge that helped accelerate them over others 2) Advancement of certain civilization is not a necessary indication they are better, smarter, more hard working, but an indication of accumulated knowledge resulting from #1 over a long period of time 3) #2 culminated in Europeans dominating the world over the better part of last 500 years
