“Any culture is coarse when you’re living in it,” insists University of Virginia professor Paul A. Cantor. “The culture Shakespeare lived in was spectacularly coarse." Cantor believes pop culture is almost always vulgar, so the goal of smart media consumers should be to find the “people who work within the coarse culture, but work to elevate it.” The good news is that his new book, “The Invisible Hand in Popular Culture,” seeks to do just that.
