Pinker's Evolutionary Delusions of Peace

“Today we take it for granted that war happens in smaller, poorer and more backward countries,” Steven Pinker writes in his new book, The Better Angels of Our Nature: the Decline of Violence in History and Its Causes. The celebrated Harvard professor of psychology is discussing what he calls “the Long Peace”: the period since the end of the second world war in which “the great powers, and developed states in general, have stopped waging war on one another.” As a result of “this blessed state of affairs,” he notes, “two entire categories of war—the imperial war to acquire colonies, and the colonial war to keep them—no longer exist.” Now and then there have been minor conflicts. “To be sure, [the super-powers] occasionally fought each other’s smaller allies and stoked proxy wars among their client states.” But these episodes do not diminish Pinker’s enthusiasm about the Long Peace.
