Larry Arnn of Hillsdale College revisits George Orwell’s classic dystopian novel in the latest issue of Imprimis.

In Orwell’s 1984, there are telescreens everywhere, as well as hidden cameras and microphones. Nearly everything you do is watched and heard. It even emerges that the watchers have become expert at reading people’s faces. The organization that oversees all this is called the Thought Police.

If it sounds far-fetched, look at China today: there are cameras everywhere watching the people, and everything they do on the Internet is monitored. Algorithms are run and experiments are underway to assign each individual a social score. If you don’t act or think in the politically correct way, things happen to you—you lose the ability to travel, for instance, or you lose your job. It’s a very comprehensive system. And by the way, you can also look at how big tech companies here in the U.S. are tracking people’s movements and activities to the extent that they are often able to know in advance what people will be doing. Even more alarming, these companies are increasingly able and willing to use the information they compile to manipulate people’s thoughts and decisions.

The protagonist of 1984 is a man named Winston Smith. He works for the state, and his job is to rewrite history. He sits at a table with a telescreen in front of him that watches everything he does. To one side is something called a memory hole—when Winston puts things in it, he assumes they are burned and lost forever. …

… The law of contradiction also means that we can’t change the past. What we can know of the truth all resides in the past, because the present is fleeting and confusing and tomorrow has yet to come. The past, on the other hand, is complete. Aristotle and Thomas Aquinas go so far as to say that changing the past—making what has been not to have been—is denied even to God.
