Do we have alcohol to thank for civilization? The answer, according to Edward Slingerland’s new book, “Drunk: How We Sipped, Danced, and Stumbled Our Way to Civilization,” is a resounding yes. Edward, who’s a professor at the University of British Columbia and self-proclaimed “philosophical hedonist,” says that far from being an evolutionary fluke, our taste for alcohol is an evolutionary advantage — one that we’ve relied on for millennia to help us lead more social, creative, and pleasurable lives.
