Spite seems utterly useless. You don't gain anything by hurting yourself just so you can hurt someone else. So why hasn't evolution weeded out all the spiteful people? As psychologist Simon McCarthy-Jones argues, spite seems pointless because we're looking at it wrong. Spite is our fairness instinct, an innate resistance to exploitation, and it is one of the building blocks of human civilization. As McCarthy-Jones explains, some of history's most important developments—the rise of religions, governments, and even moral codes—were actually redirections of spiteful impulses. A provocative, engaging read, Spite shows that if you really want to understand what makes us human, you can't just look at noble ideas like altruism and cooperation. You need to understand our darker impulses as well. (This title may contain a sharpie mark on the top or bottom edge and may show mild signs of shelfwear.)
