The mutability of the past is the central tenet of Ingsoc. Past events, it is argued, have no objective existance, but survive only in written records and in human memories. The past is whatever the records and the memories agree upon. And since the Party is in full control of all records, and in equally full control of the minds of its members, it follows that the past is whatever the Party chooses to make it.
George OrwellA totalitarian state is in effect a theocracy, and its ruling caste, in order to keep its position, has to be thought of as infallible. But since, in practice, no one is infallible, it is frequently necessary to rearrange past events in order to show that this or that mistake was not made, or that this or that imaginary triumph actually happened.
George Orwell... what is peculiar to our own age is the abandonment of the idea that history could be told truthfully.
George OrwellDo you remember writing in your diary," he said, "that it did not matter whether I was a friend or an enemy, since I was at least a person who understood you and could be talked to? You were right. I enjoy talking to you. Your mind appeals to me. It resembles my own mind except that you happen to be insane.
