This moralisation of the individual by the crowd is not certainly a constant rule, but it is a rule frequently observed. It is even observed in circumstances much less grave than those I have just cited. I have remarked that in the theatre a crowd exacts from the hero of the piece exaggerated virtues, and it is a commonplace observation that an assembly, even though composed of inferior elements, shows itself as a rule very prudish. The debauchee, the souteneur, the rough often break out into murmurs at a slightly risky scene or expression, though they be very harmless in comparison with their customary conversation. If, then, crowds often abandon themselves to low instincts, they also set the example at times of acts of lofty morality. If disinterestedness, resignation, and absolute devotion to a real or chimerical ideal are moral virtues, it may be said that crowds often possess these virtues to a degree rarely attained by the wisest philosophers. Doubtless they practice them unconsciously, but that is of small import. We should not complain too much that crowds are more especially guided by unconscious considerations and are not given to reasoning. Had they, in certain cases, reasoned and consulted their immediate interests, it is possible that no civilisation would have grown up on our planet and humanity would have had no history. CHAPTER III THE IDEAS, REASONING POWER, AND IMAGINATION OF CROWDS 1. THE IDEAS OF CROWDS. Fundamental and accessory ideas--How contradictory ideas may exist simultaneously--The transformation that must be undergone by lofty ideas before they are accessible to crowds-- The social influence of ideas is independent of the degree of truth they may contain. 2. THE REASONING POWER OF CROWDS. Crowds are not to be influenced by reasoning--The reasoning of crowds is always of a very inferior order--There is only the appearance of analogy or succession in the ideas they associate. 3. THE IMAGINATION OF CROWDS. Strength of the imagination of crowds--Crowds think in images, and these images succeed each other without any connecting link--Crowds are especially impressed by the marvellous--Legends and the marvellous are the real pillars of civilisation--The popular imagination has always been the basis of the power of statesmen--The manner in which facts capable of striking the imagination of crowds present themselves for observation. 1. THE IDEAS OF CROWDS WHEN studying in a preceding work the part played by ideas in the evolution of nations, we showed that every civilisation is the outcome of a small number of fundamental ideas that are very rarely renewed. We showed how these ideas are implanted in the minds of crowds, with what difficulty the process is effected, and the power possessed by the ideas in question when once it has been accomplished. Finally we saw that great historical perturbations are the result, as a rule, of changes in these fundamental ideas.
