“A truer statement hasn’t been uttered: “Our “groupiness” shapes human history.”  Mark Moffett’s book is a wide-ranging, deeply interesting analysis of how large numbers of individual agents become a society.  His travels in the world and through vast intellectual landscapes give him a unique view of why we are the way we are, both in our similarity to other living beings and our differences from them – our ability to include once alien groups into our own, for example.  There is no other book I’ve read recently that made my neurons pop at the rate this book did.”
