Jared Diamondโs Guns, Germs, and Steel shouldโve actually been called Germs, Christianity, Culture, and Economics. Christianity was the vital cultural technology that allowed such a violent and comprehensive imperial expansion, and economic ideas and technologies (also heavily influenced by Christianity) provided the engine thereof.
There can be non-experts in a field who write a book that is perspicacious and breaks new ground. Alas, Diamondโs book is not one of those. It is anthropologically unsound, ashistorical, and ignores the most important elements in favor of relatively-unimportant ones (guns, steel).
Diamond went the long, stupid way โround to โproveโ the genetic non-superiority of European populations. The whole idea of genetic superiority is already prima facie idiotic, so why all the โbeing colossally wrongโ was necessary, I havenโt any idea.
Itโs not that all of Diamondโs ideas are wrong, or even bad. Itโs that history is far, far more contingent than Diamond gives credit for, and if events had turned a little differently, Diamond wouldโve been able to find post hoc reasons for why they occurred, too.
