“The pressure to make public retractions of past statements—there's something medieval about it. What does it mean, anyway, to 'retract' what you've said? How can anyone state categorically that a thought he once had is no longer valid? In modern times an idea can be refuted, yes, but not retracted. And since to retract an idea is impossible, merely verbal, formal sorcery, I see no reason why you shouldn't do as they wish. In a society run by terror, no statements whatsoever can be taken seriously. They are all forced, and it is the duty of every honest man to ignore them.”
