During part of 1941 and 1942, when the Luftwaffe was busy in Russia, the German radio regaled its home audience with stories of devastating air raids on London. Now, we are aware that those raids did not happen. But what use would our knowledge be if the Germans conquered Britain? For the purpose of a future historian, did those raids happen, or didn't they? The answer is: If Hitler survives, they happened, and if he falls they didn't happen.
George OrwellIn a way, the world-view of the Party imposed itself most successfully on people incapable of understanding it. They could be made to accept the most flagrant violations of reality, because they never fully grasped the enormity of what was demanded of them, and were not sufficiently interested in public events to notice what was happening. By lack of understanding they remained sane. They simply swallowed everything, and what they swallowed did them no harm, because it left no residue behind, just as a grain of corn will pass undigested through the body of a bird.
