It is a common fallacy to regard great movements in history as the work of one great prophet, to think that he alone changed the current of human events by the force of a single dynamic personality. As a matter of fact, great movements, such as the Reformation, have been produced because an unusually large number of prophets arose at the same time. Though the names of only a few have been illumined by fame, the deeds of the rest were just as necessary for the success of the movement.
