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

“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.”

“To hold in the mind forever two ideas which seemed to be in opposition. The first . . . acceptance totally without rancor, of life as it is, and men as they are [;] . . . the second . . . that one must never, in one's life, accept . . . injustices as commonplace but must fight them with all one's strength.”

“Maturity is when you accept the fact that two contradictory ideas can exist together.”

“Now, when their glances met, they understood one another. The power that lay within both their souls had met, and, as it were, clasped hands. They accepted one another's sacrifice. Hers, mayhap, was the more complete of the two, because for her his absence would mean weary waiting, the dull heartache so terrible to bear.”

“Yet, isn't it strange, isn't it weird, how we can KNOW that someone is not behaving in the way we imagine, and at the same time we can be totally convinced that he is! How clever the human mind is, that it can accept two contradictory things as 'facts.' Yes, I know that in this case one 'fact' was untrue. But the human mind can KNOW something is untrue and still accept it as a 'fact,' and act on it as if it were true.”
