Why Wars Happen (w/ Michael Mann)

Michael Mann is a sociologist who has spent his life trying to understand how power works. His latest book, On Wars, surveys the entire history of warfare between human societies to try to understand why wars happen and how they can be avoided. It is the culmination of a decade-long effort by Mann to try to comprehensively understand the origins of war. (See the New York Times review of Mann's book here.) Today he joins to help us better understand war. Are humans naturally warlike? Are wars rational ways to achieve political goals? Mann addresses the Steven Pinker narrative that civilization and enlightenment have brought about greater peace—in fact, he says, "civilization" has allowed us to build more efficient killing machines than ever. And he tells us what he knows on the subject that should interest all of us in the nuclear age: How do we end war? 

Note that this episode was recorded before the recent explosion of the Israel-Palestine conflict, so it is not addressed in the discussion. 

“War is the one instance where losing one’s temper may cause the death of thousands. War pays us back more swiftly for mistakes than any other human activity. Humans are not calculating machines—more’s the pity, since peace is more rational than war. If the social world did conform to rational theory, if rulers did carefully calculate the costs and benefits of war, trying hard to set emotions and ideologies aside and ignoring domestic political pressures, they would see that most wars are too risky and inferior to economic exchange, the sharing of norms and values, and diplomacy as ways of securing desired goals..War is the least rational of human projects, but humans are only erratically rational creatures...Human beings are not genetically predisposed to make war, but our human nature does matter, if indirectly. Its tripartite character, part rational, part emotional, part ideological, when set inside the institutional and cultural constraints of societies, makes war an intermittent outcome. Human nature does matter, and that is why when wars are fought, they are mostly fought for no good reason.” — Michael Mann, On Wars
