"Rosa Luxemburg’s name is less well-known in other countries than it is to us in Russia. But one can say with all certainty that she was in no way a lesser figure than Karl Liebknecht. Short in height, frail, sick, with a streak of nobility in her face, beautiful eyes and a radiant mind she struck one with the bravery of her thought. She had mastered the Marxist method like the organs of her body. One could say that Marxism ran in her blood stream. I have said that these two leaders, so different in nature, complemented each other. I would like to emphasize and explain this. If the intransigent revolutionary Liebknecht was characterized by a feminine tenderness in his personal ways then this frail woman was characterized by a masculine strength of thought. Ferdinand Lassalle once spoke of the physical strength of thought, of the commanding power of its tension when it seemingly overcomes material obstacles in its path. That is just the impression you received talking to Rosa, reading her articles or listening to her when she spoke from the tribune against her enemies. And she had many enemies! I remember how, at a congress at Jena I think, her high voice, taut like a wire, cut through the wild protestations of opportunists from Bavaria, Baden and elsewhere. How they hated her! And how she despised them! Small and fragilely built she mounted the platform of the congress as the personification of the proletarian revolution. By the force of her logic and the power of her sarcasm she silenced her most avowed opponents. Rosa knew how to hate the enemies of the proletariat and just because of this she knew how to arouse their hatred for her. She had been identified by them early on. From the first day, or rather from the first hour of the war, Rosa Luxemburg launched a campaign against chauvinism, against patriotic lechery, against the wavering of Kautsky and Haase and against the centrists’ formlessness; for the revolutionary independence of the proletariat, for internationalism and for the proletarian revolution...By the force of the strength of her theoretical thought and her ability to generalize Rosa Luxemburg was a whole head above not only her opponents but also her comrades. She was a woman of genius. Her style, tense, precise, brilliant and merciless, will remain for ever a true mirror of her thought."
