FOR A WHILE George Orwell thought of calling his novel about life in a totalitarian future The Last Man in Europe. But in the end that title didn’t quite satisfy him, and he chose another simply by reversing the last two digits of the year in which he finished the manuscript. It is a good indication of the book’s enduring power that as the year thus whimsically chosen approached, a score of magazines came out with articles assessing the actual state of the world in 1984 against Orwell’s vision of it in Nineteen Eighty-Four, and offering edgy reassurances that things aren’t quite so bad as he’d predicted.
