Peter Dobrin: “The good news is our Facebook news feeds have made it nearly impossible to ignore injustice. The bad news is injustice is inexhaustible, and we are not. So turning it off and looking for escape in the theater, gallery, library reading room, or concert hall has greater appeal than ever. The best news of all, though, is that sitting in the presence of art is both escape and an act of confrontation with the barbarians, however you might define them.”
