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. . . . The heresy of heresies was common sense. . . . The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command.
— George Orwell, 1984
