"The aim of my life is the overthrow of monarchy. As my father, who appeared before this court exactly thirty-five years ago to defend himself against the charge of treason, was ultimately pronounced victor, so I believe the day is not far distant when the principles which I represent will be recognized as patriotic, as honorable, as true." KARL LIEBKNECHT. PREFACE The philosophy of Karl Liebknecht as revealed in these pages leaves but a narrow ledge for heroes to stand on. To him the significant thing in history is, and has always been, the stirring of the masses of men at the bottom, their unconscious writhings, their awakenings, their conscious struggles and finally their gigantic, fearsome upthrust, which overturns all the little groups of clever men who have lived by holding these masses down. In these conflicts, kings, priests, leaders, heroes count for no more than flags or flying pennants. All great leaders, Caesar, Mahomet, Luther, Napoleon, are instruments of popular movements, or at best manuscripts upon which the messages of their class and age have been written. To Liebknecht all that Carlyle has said about heroes is contrary to ideology and inversion of the truth. "As I take it," writes Carlyle, "Universal History, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked there. They were the leaders of men, these great ones; the modellers, patterns, and in a wide sense creators, of whatsoever the general mass of men contrived to do or to attain; all things that we see standing and accomplished in the world are properly the outward 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, were the history of these." Look at what is happening in Germany to-day and test, as best we may, these two confronting theories concerning the influence of great men upon history. As I write Germany is in the throes of revolution. The immensely powerful Hohenzollern monarchy has fallen, the brave, stubborn, modern-witted, money-bolstered aristocracy is shattered, and a proscribed poor man, Karl Liebknecht, is loudly acclaimed. Was it one man, a Foch, a Wilson, a Lenin or a Liebknecht that overturned this mighty structure, or was it the movement of a hundred million men and women, armed and unarmed, on the battle-field and in the factory, in France and England and Russia and Germany? What could Liebknecht alone have done with all his ringing eloquence and all his superb, I almost said, sublime heroism? Clearly we must rule Carlyle out of the controversy and agree with Liebknecht, the Socialist, that Liebknecht, the hero, had little to do with this vast subversion. Yet, as Carlyle says, "One comfort is, that Great Men, taken up in any way, are profitable company. We cannot look, however imperfectly, upon any great man, without gaining something by him."
