But there is not only doubt about mystical things; not even only about moral things. There is most doubt of all about rational things. I do not mean that I feel these doubts, either rational or mystical; but I mean that a sufficient number of modern people feel them to make unanimity an absurd assumption....[T]his scepticism is throwing thousands into a condition of doubt, not about [mystical] but about obvious things. We shall soon be in a world in which a man may be howled down for saying that two and two make four, in which furious party cries will be raised against anybody who says that cows have horns, in which people will persecute the heresy of calling a triangle a three-sided figure, and hang a man for maddening a mob with the news that grass is green.
