The convictions of crowds assume those characteristics of blind submission, fierce intolerance, and the need of violent propaganda which are inherent in the religious sentiment, and it is for this reason that it may be said that all their beliefs have a religious form. The hero acclaimed by a crowd is a veritable god for that crowd. Napoleon was such a god for fifteen years, and a divinity never had more fervent worshippers or sent men to their death with greater ease. The Christian and Pagan Gods never exercised a more absolute empire over the minds that had fallen under their sway. All founders of religious or political creeds have established them solely because they were successful in inspiring crowds with those fanatical sentiments which have as result that men find their happiness in worship and obedience and are ready to lay down their lives for their idol. This has been the case at all epochs. Fustel de Coulanges, in his excellent work on Roman Gaul, justly remarks that the Roman Empire was in no wise maintained by force, but by the religious admiration it inspired. "It would be without a parallel in the history of the world," he observes rightly, "that a form of government held in popular detestation should have lasted for five centuries. . . . It would be inexplicable that the thirty legions of the Empire should have constrained a hundred million men to obedience." The reason of their obedience was that the Emperor, who personified the greatness of Rome, was worshipped like a divinity by unanimous consent. There were altars in honour of the Emperor in the smallest townships of his realm. "From one end of the Empire to the other a new religion was seen to arise in those days which had for its divinities the emperors themselves. Some years before the Christian era the whole of Gaul, represented by sixty cities, built in common a temple near the town of Lyons in honour of Augustus. . . . Its priests, elected by the united Gallic cities, were the principal personages in their country. . . . It is impossible to attribute all this to fear and servility. Whole nations are not servile, and especially for three centuries. It was not the courtiers who worshipped the prince, it was Rome, and it was not Rome merely, but it was Gaul, it was Spain, it was Greece and Asia." To-day the majority of the great men who have swayed men's minds no longer have altars, but they have statues, or their portraits are in the hands of their admirers, and the cult of which they are the object is not notably different from that accorded to their predecessors. An understanding of the philosophy of history is only to be got by a thorough appreciation of this fundamental point of the psychology of crowds. The crowd demands a god before everything else.
