Nineteen Eighty-Four expands upon the subjects summarised in Orwell's essay "Notes on Nationalism" about the lack of vocabulary needed to explain the unrecognised phenomena behind certain political forces. In Nineteen Eighty-Four, the Party's artificial, minimalist language 'Newspeak' addresses the matter.
- Positive nationalism: For instance, Oceanians' perpetual love for Big Brother. Orwell argues in the essay that ideologies such as Neo-Toryism and Celtic nationalism are defined by their obsessive sense of loyalty to some entity.
- Negative nationalism: For instance, Oceanians' perpetual hatred for Emmanuel Goldstein. Orwell argues in the essay that ideologies such as Trotskyism and Antisemitism are defined by their obsessive hatred of some entity.
- Transferred nationalism: For instance, when Oceania's enemy changes, an orator makes a change mid-sentence, and the crowd instantly transfers its hatred to the new enemy. Orwell argues that ideologies such as Stalinism and redirected feelings of racial animus and class superiority among wealthy intellectuals exemplify this. Transferred nationalism swiftly redirects emotions from one power unit to another. In the novel, it happens during Hate Week, a Party rally against the original enemy. The crowd goes wild and destroys the posters that are now against their new friend, and many say that they must be the act of an agent of their new enemy and former friend. Many of the crowd must have put up the posters before the rally but think that the state of affairs had always been the case.
O'Brien concludes: "The object of persecution is persecution. The object of torture is torture. The object of power is power."
In the book, Inner Party member O'Brien describes the Party's vision of the future:
There will be no curiosity, no enjoyment of the process of life. All competing pleasures will be destroyed. But always—do not forget this, Winston—always there will be the intoxication of power, constantly increasing and constantly growing subtler. Always, at every moment, there will be the thrill of victory, the sensation of trampling on an enemy who is helpless. If you want a picture of the future, imagine a boot stamping on a human face—forever.— Part III, Chapter III, Nineteen Eighty-Four
One of the most notable themes in Nineteen Eighty-Four is censorship, especially in the Ministry of Truth, where photographs and public archives are manipulated to rid them of "unpersons" (people who have been erased from history by the Party). On the telescreens, almost all figures of production are grossly exaggerated or simply fabricated to indicate an ever-growing economy, even during times when the reality is the opposite. One small example of the endless censorship is Winston being charged with the task of eliminating a reference to an unperson in a newspaper article. He also proceeds to write an article about Comrade Ogilvy, a made-up party member who allegedly "displayed great heroism by leaping into the sea from a helicopter so that the dispatches he was carrying would not fall into enemy hands."
In Oceania, the upper and middle classes have very little true privacy. All of their houses and apartments are equipped with telescreens so that they may be watched or listened to at any time. Similar telescreens are found at workstations and in public places, along with hidden microphones. Written correspondence is routinely opened and read by the government before it is delivered. The Thought Police employ undercover agents, who pose as normal citizens and report any person with subversive tendencies. Children are encouraged to report suspicious persons to the government, and some denounce their parents. Citizens are controlled, and the smallest sign of rebellion, even something as small as a suspicious facial expression, can result in immediate arrest and imprisonment. Thus, citizens are compelled to obedience.
