The novelist George Orwell coined the term doublethink in his classic dystopian novel 1984. He defined doublethink as
"The power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them...To tell deliberate lies while genuinely believing in them, to forget any fact that has become inconvenient, and then, when it becomes necessary again, to draw it back from oblivion for just as long as it is needed, to deny the existence of objective reality and all the while to take account of the reality which one denies."Although the concept is elucidated in a work of fiction, it has clear and unmistakable parallels in the real world that, like Oceania - the supranational state in which the novel takes place - is in a state of constant war, and seemingly has been from time immemorial.
