The arousing of faith--whether religious, political, or social, whether faith in a work, in a person, or an idea--has always been the function of the great leaders of crowds, and it is on this account that their influence is always very great. Of all the forces at the disposal of humanity, faith has always been one of the most tremendous, and the gospel rightly attributes to it the power of moving mountains. To endow a man with faith is to multiply his strength tenfold. The great events of history have been brought about by obscure believers, who have had little beyond their faith in their favour. It is not by the aid of the learned or of philosophers, and still less of sceptics, that have been built up the great religions which have swayed the world, or the vast empires which have spread from one hemisphere to the other. In the cases just cited, however, we are dealing with great leaders, and they are so few in number that history can easily reckon them up. They form the summit of a continuous series, which extends from these powerful masters of men down to the workman who, in the smoky atmosphere of an inn, slowly fascinates his comrades by ceaselessly drumming into their ears a few set phrases, whose purport he scarcely comprehends, but the application of which, according to him, must surely bring about the realisation of all dreams and of every hope. In every social sphere, from the highest to the lowest, as soon as a man ceases to be isolated he speedily falls under the influence of a leader. The majority of men, especially among the masses, do not possess clear and reasoned ideas on any subject whatever outside their own speciality. The leader serves them as guide. It is just possible that he may be replaced, though very inefficiently, by the periodical publications which manufacture opinions for their readers and supply them with ready- made phrases which dispense them of the trouble of reasoning. The leaders of crowds wield a very despotic authority, and this despotism indeed is a condition of their obtaining a following. It has often been remarked how easily they extort obedience, although without any means of backing up their authority, from the most turbulent section of the working classes. They fix the hours of labour and the rate of wages, and they decree strikes, which are begun and ended at the hour they ordain.
