The contradictory language in each phrase presents repulsive and dangerous experiences (such as slavery and war) as desirable and attractive ideologies to aspire to, creating a feedback loop in which the party's ultimate goals are accepted and admired by the populations. Furthermore, these paradoxical statements redefine the meaning of traditional language, weakening it and thus the possibility of rebellion that it could potentially offer. If freedom, for example, is rent from its original meaning, the citizens of Oceania are no longer able to aspire towards it, or even conceptualise it. The absolutist 'is' emphasises that the party's message is law, and there cannot be any resistance to it, presenting it as a fact that cannot be resisted. Furthermore, the repetitive pattern creates a subliminal and consistent message that becomes hard to resist or change. Lastly, the forcing of simultaneously contradictory beliefs next to each other creates constant confusion and self-correction as the party members are forced to interrogate and change their own beliefs, preventing them from forming clear thoughts and thus questioning or challenging the party's rhetoric.
AO3/CONTEXT: The repetitive nature of the slogan may have been inspired by Orwell's experience of consistent and everpresent propaganda in the Second World War, particularly that of the Soviets.. The repetitive slogans of the Soviet party, such as the oft-touted 'Workers of the World, Unite!' consistently reinforced the values and ideas of the Soviet government, creating a culture in which it was difficult to refuse or resist Soviet ideals. The repetitive nature, like the slogans of Oceania, made them difficult to resist.
AO5/Interpretations: Interpreted using a psychoanalytic approach like that of Michael Silverstein, who argued that evolutions in language over time create evolutions in our understandings of concepts, the party's manipulation of language could be seen as an attempt over time to erode the ideas of free thought, instead shaping the world into what the party wants it to be.
