George Orwell’s “1984,” published seventy years ago today, has had an amazing run as a work of political prophecy. It has outlasted in public awareness other contenders from its era, such as Aldous Huxley’s “Brave New World” (1932), Ray Bradbury’s “Fahrenheit 451” (1953), and Anthony Burgess’s “A Clockwork Orange” (1962), not to mention two once well-known books to which it is indebted, Yevgeny Zamyatin’s “We” (1921) and Arthur Koestler’s “Darkness at Noon” (1940). “1984” is obviously a Cold War book, but the Cold War ended thirty years ago. What accounts for its staying power?

Partly it’s owing to the fact that, unlike “Darkness at Noon,” Orwell’s book was not intended as a book about life under Communism. It was intended as a warning about tendencies within liberal democracies, and that is how it has been read. The postwar Sovietization of Eastern Europe produced societies right out of Orwell’s pages, but American readers responded to “1984” as a book about loyalty oaths and McCarthyism. In the nineteen-seventies, it was used to comment on Nixon and Watergate. There was a bounce in readership in 1983-84—four million copies were sold that year—because, well, it was 1984. And in 2016 it got a bump from Trump.

The fundamental premise of the novel was its most quickly outmoded feature—outmoded almost from the start. This is the idea that the world would divide into three totalitarian superstates that were rigidly hierarchical, in complete control of information and expression, and engaged in perpetual and unwinnable wars for world domination. This was a future that many people had contemplated in the nineteen-thirties, the time of the Great Depression and the rise of Stalinism and Fascism. Capitalism and liberal democracy seemed moribund; centralized economies and authoritarian regimes looked like the only way modern mass societies could be governed. This was the argument of a book that is now almost forgotten, but which Orwell was fascinated and repelled by, James Burnham’s “The Managerial Revolution” (1941).

It’s true that, after 1949, the world did divide into superstates—not three, but two—and their forty-year rivalry did a lot of damage around the world. But they were not twin totalitarian monsters, the Fasolt and Fafner of twentieth-century geopolitics. They may often have mirrored each other in tactics, but they were different systems defending different ideologies. Orwell, who had little interest in and no fondness for the United States, missed that.

There are some parts of the novel whose relevance seems never to fade, though. One is the portrayal of the surveillance state—Big Brother (borrowed from Koestler’s No. 1) and the telescreen, an astonishingly prescient conception that Orwell dreamed up when he had probably never seen a television. Another is Newspeak, a favorite topic of Orwell’s: the abuse of language for political purposes.

But “1984” is a novel, not a work of political theory, and, in the end, it’s probably as literature that people keep reading it. The overt political material—such as “The Theory and Practice of Oligarchical Collectivism,” the (very long) book that the commissar O’Brien gives to Winston and Julia as he lures them into the trap—is likely now skipped by many readers. (The book’s analogue is “The Revolution Betrayed,” Leon Trotsky’s attack on Stalinism, published in 1937, but it is also a parody of “The Managerial Revolution.”)

O’Brien’s interrogation of Winston, though meant to be the climax of the book, and though people still invoke it, is not completely satisfactory. How does O’Brien convince Winston that two plus two equals five? By torturing him. This seems a rather primitive form of brainwashing. In “Darkness at Noon,” which also ends with an interrogation, the victim, Rubashov, though he is worn down physically first, is defeated intellectually. (Both novelists were attempting to understand how, in the Moscow Trials, Stalin’s purge of the Old Bolsheviks, between 1936 and 1938, the defendants, apparently of their own free will, admitted to the most absurd charges against them, knowing that they would be promptly shot. After Stalin’s death, it turned out that those defendants had, in fact, been tortured. So Orwell was right about that.)

But who can forget this moment: “ ‘You are the dead,’ said an iron voice behind them”? Orwell created a story that had suspense and had characters whom readers identify with.

When the book came out, some people assumed that the character they were meant to identify with (with horror) was O’Brien. That’s probably what Orwell had in mind, too. O’Brien was the type he wanted to warn people against: the intellectual who becomes sadistically fascinated by power. The O’Brien figure corresponded to a popular understanding of the lure of totalitarianism at the time: that it tapped into some dark corner of the human psyche. “There is a Hitler, a Stalin in every breast,” as Arthur Schlesinger, Jr., put it in his liberal manifesto, “The Vital Center,” which was published the same year as “1984.”

Much later, Schlesinger changed his mind and rejected what he called Orwell’s “mystical theory of totalitarianism.” For we are not all O’Briens, waiting for the chance to torture the Winstons of the world. We are more likely all Winstons, knowing that something is wrong, that we are losing control of our lives, but also knowing that we are powerless to resist.

A trivial example is when we click “I Agree” on the banner explaining our app’s new privacy policy. We did not know what the old privacy policy was; we feel fairly certain that, if we read the new one, we would not understand what has changed or what we are giving away. We suspect everyone else just clicks the box. So we click the box and dream of a world in which there are no boxes to click. A non-trivial example is when your electoral process is corrupted by a foreign power and your government talks about charging the people who tried to investigate this interference with treason. That’s Orwellian. And it’s no longer a prophecy. It’s a headline.
