Albert Camus, in "PLAGUE", says: two and two make four but the teacher who teaches that two and two make four is not rewarded for teaching that two and two make four ; but a time comes in the history when the person who says that two and two make four is punished with death ; the question, however, is not what punishment or reward awaits the man who says that two and two make four : the question is whether two and two do make four.
