doublethink（n.）
"同时持有两种矛盾信念并接受它们"（奥威尔），1948年，由乔治·奥威尔在《1984》中创造，来自 double（形容词）+ think。
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. ["Nineteen Eighty-Four"]
知道而又不知道，当你讲述精心构造的谎言时，意识到完全真实，同时持有两种相互抵消的观点，知道它们是矛盾的并相信它们，用逻辑反对逻辑，否认道德却声称拥有它，相信民主是不可能的，而党是民主的守护者，忘记必要的事情，然后在需要的时候将其重新记起，然后立即再次忘记，最重要的是，将同样的过程应用于过程本身——这是最终的微妙之处：有意识地诱导无意识，然后再次变得无意识，忘记你刚刚执行的催眠行为。即使理解这个词——双重思想——也涉及到使用双重思想。["1984"]
