“If the Party could thrust its hand into the past and say of this or that event, it never happened—that, surely, was more terrifying than mere torture and death.”

“Nazi theory indeed specifically denies that such a thing as "the truth" exists. […] The implied objective of this line of thought is a nightmare world in which the Leader, or some ruling clique, controls not only the future but the past. If the Leader says of such and such an event, "It never happened"—well, it never happened. If he says that two and two are five—well, two and two are five. This prospect frightens me much more than bombs […]”

“A 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.”

“She had grasped the inner meaning of the Party's sexual puritanism. It was not merely that the sex instinct created a world of its own which was outside the Party's control and which therefore had to be destroyed if possible. What was most important was that sexual privation induced hysteria, which was desirable because it could be transformed into war fever and leader worship.”

“There it lay, fixed in future time, preceding death as surely as 99 precedes 100. One could not avoid it, but one could perhaps postpone it: and yet instead, every now and again, by a conscious, willful act, one chose to shorten the interval before it happened.”

“In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable—what then?”

“In 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.”
