For good or evil, the possession, the cultivation, and the exhibition of the qualities of leadership give men enormous power. There was in the nineteenth century a historical fashion, brilliantly exemplified by Carlyle, to assume that history was made by great men. Latterly, there has been wide dissent from this simplification of the processes of history, but it is clear that innovations must be started by individuals, and that a powerful leader is a matchless instrument for initiating, and getting wide and enthusiastic support for changes, whether good or bad. To quote Carlyle's eloquent exaggeration: For, as I take it, Universal History, the history of what man has accomplished in this world, is at the bottom the History of the Great Men who have worked here. They were the leaders of men, ... the creators of whatsoever the general mass of men contrived to do or to attain; all things that we see standing accomplished in the world are properly the outer material result, the practical realization and embodiment, of thoughts that dwelt in the Great Men sent into the world: the soul of the whole world's history, it may justly be considered, was the history of these.... Could we see _them_ well, we should get some glimpses into the very marrow of the world's history.[1] [Footnote 1: Carlyle: _Heroes and Hero-Worship_, Lecture I.] Later Nietzsche made much of this same idea, of the Superman striding through the world and changing its destiny, although in Nietzsche the Superman was an end in himself rather than the servant of the world in which he lived. To most historical writers to-day the forces at work in history are much too complex to be dismissed with any such simple melodrama. But there remain striking testimonies of the influence of leaders. The sweep of Mohammedanism into Europe was initiated by the burning and contagious zeal of one religious enthusiast. The campaign against slavery in this country assumed large proportions through the strenuous leadership of the Garrisons and the Wendell Phillipses. In our own day we have seen the same phenomenon; the great political and social changes of the last generation have all had their special advocates and leaders who, if they were merely expressing the "spirit of the times," yet did give that spirit expression. Every reform or revolution has its leading spirits. That leadership is not the one essential goes without saying; there have been great guides of repeatedly lost causes. But many great causes may have been lost through the want of good leadership. In contemporary life leadership is not always directly personal, but is carried on through the medium of the newspapers and periodicals. But this merely means that a leader may reach a wider audience; he reaches thousands through picture and print, instead of hundreds by word of mouth.
