The Dawn of Everything: A New History of Humanity

by David Graeber

Still, we must be cautious. While human beings have always been capable of physically attacking one another (and it’s difficult to find examples of societies where no one ever attacks anyone else, under any circumstances), there’s no actual reason to assume that war has always existed. Technically, war refers not just to organized violence but to a kind of contest between two clearly demarcated sides. As Raymond Kelly has adroitly pointed out, it’s based on a logical principle that’s by no means natural or self-evident, which states that major violence involves two teams, and any member of one team treats all members of the other as equal targets. Kelly calls this the principle of ‘social substitutability’7 – that is, if a Hatfield kills a McCoy and the McCoys retaliate, it doesn’t have to be against the actual murderer; any Hatfield is fair game. In the same way, if there is a war between France and Germany, any French soldier can kill any German soldier, and vice versa. The murder of entire populations is simply taking this same logic one step further. There is nothing particularly primordial about such arrangements; certainly, there is no reason to believe they are in any sense hardwired into the human psyche. On the contrary, it’s almost invariably necessary to employ some combination of ritual, drugs and psychological techniques to convince people, even adolescent males, to kill and injure each other in such systematic yet indiscriminate ways.
