1984

In 1984, London is no longer the capital of England: it is Airstrip One, a province of the superpower Oceania, a country run by a single party that accepts no opposition and no public discussion of its decisions. Huge posters, plastered along hallways, stairwells, and streets, show the face of a man with a thick mustache, along with a warning that he is watching whoever walks by.

Winston Smith is an employee at the Ministry of Truth, the agency in charge of the country's information, history, and official culture. He lives alone in a small, run-down apartment, typical for members of the Outer Party, the lower middle class of this official hierarchy.

Inside his home, the telescreen works as a television and a camera at the same time: it broadcasts speeches and music all day long and, along with that, picks up sound and image and sends them back to the government, with no off switch. It's as if the living room of any apartment had a security camera running 24 hours a day, even in the middle of the night, with no warning of when someone on the other end is watching. That constant surveillance is the backdrop of the whole story.

At the Ministry of Truth, Winston's job is rewriting old newspapers. Whenever a Party prediction doesn't come true, or a name falls out of favor, his task is to rewrite the old article as if it had never been said that way.

The original material, what was actually published once upon a time, becomes obsolete and goes down a chute called the memory hole, which leads straight to the incinerator. No trace is left of what existed before.

The practical effect is simple to grasp: if no one can prove what happened yesterday, whoever holds power today decides alone which version of history counts. Winston sees this clearly in his own work, but it would take him a while to turn that clarity into any kind of action.

The novel uses the word doublethink to describe a mental habit the Party cultivates in everyone: holding two contradictory beliefs in your head, accepting both as true at the same time, without feeling the clash between them.

The very names of the ministries show this trick at work: the Ministry of Truth handles official lies, the Ministry of Peace runs the permanent war, the Ministry of Love is where the torture happens, and the Ministry of Plenty manages rationing and scarcity.

You can spot a milder cousin of this habit in ordinary situations: that moment at work when you repeat a rule you know makes no sense, just because challenging it takes more effort than swallowing it. The book takes this mental engineering to the extreme, to the point where a person stops noticing they are contradicting themselves.
