Let us try to grasp the immensity of the task actually executed by Marx. First, consider his scientific work. During all the period of these many battles every leisure moment was spent in study. While others were engaged in organizing what they were pleased to call the "Revolution" and waiting about for it to start, Marx, Engels, Liebknecht, and all this group were spending innumerable hours in the library. We see the result of that labor in the three great volumes of "Capital," in many pamphlets, and in other writings. By this painstaking scientific work of Marx the nature of capitalism was made known and, consequently, what it was that should be combated, and how the battle should be waged. In addition to these studies, which have been of such priceless value to the labor and socialist movements of the world, Marx, by his pitiless logic and incessant warfare, destroyed every revolution-maker, and then, by an act of surgery that many declared would prove fatal, cut out of the labor movement the "pan-destroyers." Once more, by a supreme effort, he turned the thought of labor throughout the world to the one end and aim of winning its political weapons, of organizing its political armies, and of uniting the working classes of all lands. Here, then, is a brief summary of the work of this genius, who fertilized with his powerful thoughts the proletarian movements of both worlds. The most wonderful thing of all is that, in his brief lifetime, he should not only have planned this gigantic task, but that he should have obtained the essentials for its complete accomplishment.
