“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, to use logic against logic, to repudiate morality while laying claim to it, to believe that democracy was impossible and that the Party was the guardian of democracy, to forget whatever it was necessary to forget, then to draw it back into memory again at the moment when it was needed, and then promptly to forget it again: and above all, to apply the same process to the process itself -- that was the ultimate subtlety: consciously to induce unconsciousness, and then, once again, to become unconscious of the act of hypnosis you had just performed. Even to understand the word 'doublethink' involved the use of doublethink.”

“Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them.”

“I believe that on such an issue as this no one is or can be completely truthful. It is difficult to be certain about anything except what you have seen with your own eyes, and consciously or unconsciously everyone writes as a partisan”

“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?”

“The Ministry of Peace concerns itself with war, the Ministry of Truth with lies, the Ministry of Love with torture and the Ministry of Plenty with starvation. These contradictions are not accidental, nor do they result from from ordinary hypocrisy: they are deliberate exercises in doublethink”

“When one watches some tired hack on the platform mechanically repeating the familiar phrases -- bestial atrocities, iron heel, bloodstained tyranny, free peoples of the world, stand shoulder to shoulder -- one often has a curious feeling that one is not watching a live human being but some kind of dummy: a feeling which suddenly becomes stronger at moments when the light catches the speaker's spectacles and turns them into blank discs which seem to have no eyes behind them. And this is not altogether fanciful. A speaker who uses that kind of phraseology has gone some distance toward turning himself into a machine. The appropriate noises are coming out of his larynx, but his brain is not involved as it would be if he were choosing his words for himself. If the speech he is making is one that he is accustomed to make over and over again, he may be almost unconscious of what he is saying, as one is when one utters the responses in church. And this reduced state of consciousness, if not indispensable, is at any rate favorable to political conformity.”

“Except for the small revolutionary groups which exist in all countries, the whole world was determined upon preventing revolution in Spain. In particular the Communist Party, with Soviet Russia behind it, had thrown its whole weight against the revolution. It was the Communist thesis that revolution at this stage would be fatal and that what was to be aimed at in Spain was not workers' control, but bourgeois democracy. It hardly needs pointing out why 'liberal' capitalist opinion took the same line.”
