One of Turchin’s most unwelcome conclusions is that complex societies arise through war. The effect of war is to reward communities that organize themselves to fight and survive, and it tends to wipe out ones that are simple and small-scale. “No one wants to accept that we live in the societies we do”—rich, complex ones with universities and museums and philosophy and art—“because of an ugly thing like war,” he said. But the data are clear: Darwinian processes select for complex socie­ties because they kill off simpler ones.
