The other night, I saw George Orwells’s 1984 performed on the London stage. Although crying out for a contemporary interpretation, Orwell’s warning about the future was presented as a period piece: remote, unthreatening, almost reassuring. It was as if Edward Snowden had revealed nothing, Big Brother was not now a digital eavesdropper and Orwell himself had never said, “To be corrupted by totalitarianism, one does not have to live in a totalitarian country.”
