In 1984, language is of central importance to behavior control. The major proposition is that if control of language were centralized in a state, then the possibility of rebellion or disobedience would be eliminated. This book devotes significant time to examining the centrality of language – explicitly, through Goldstein’s manifesto, or contextually, as in when Syme and Winston speak of the Newspeak dictionary – to history, culture, life, behavior, thoughts, concepts, and power.
Even if people communicate solely in Newspeak, and the control of language is centralized in Oceania by the Party, it would not be possible to narrow the range of thought to eliminate the possibility of subversion. Therefore, the Party’s ambitions are impossible.
Language limits thought, and thought is dependent on language. Indeed, no thought can be had without the right words with which to express it. Therefore, the Party’s ambitions are attainable.
