Uses:
His mind slid away into the labyrinthine world of doublethink. To know and not to know, to be conscious of complete truthfulness while telling carefully-constructed lies, to hold simultaneously two opinions which cancelled out, knowing them to be contradictory and believing in both of them; [...] Even to understand the world ‘doublethink’ involved the use of doublethink.
