 If the reasons why it is hard for a man to cross the mountains is because he is frightened of the devils in them, it is folly for the historian, preaching at him across a gulf of centuries, to say “This is sheer superstition, there are no devils at all. Face facts, and realize there are no dangers in the mountains except rocks and water and snow, wolves perhaps, and bad men perhaps, but no devils.” The historian says that these are the facts because that is the way in which he has been taught to think. But the devil-fearer says that the presence of devils is a fact, because that is the way in which he has been taught to think. The historian thinks it a wrong way; but wrong ways of thinking are just as much historical facts as right ones, and, no less than they, determine the situation (always a thought-situation) in which the man who shares them is placed.
