"It is characteristic of the unity of theory and practice in the life work of Rosa Luxemburg that the unity of victory and defeat, individual fate and total process is the main thread running through her theory and her life. As early as her first polemic against Bernstein’s she argued that the necessarily ‘premature’ seizure of power by the proletariat was inevitable. She unmasked the resulting opportunist fear and lack of faith in revolution as “political nonsense which starts from the assumption that society progresses mechanically and which imagines a definite point in time external to and unconnected with the class struggle in which the class struggle will be won”. It is this clear-sighted certitude that guides Rosa Luxemburg in the campaign she waged for the emancipation of the proletariat: its economic and political emancipation from physical bondage under capitalism, and its ideological emancipation from its spiritual bondage under opportunism. As she was the great spiritual leader of the proletariat her chief struggles were fought against the latter enemy – the more dangerous foe as it was harder to defeat. Her death at the hands of her bitterest enemies, Noske and Scheidemann, is, logically, the crowning pinnacle of her thought and life. Theoretically she had predicted the defeat of the January rising years before it took place; tactically she foresaw it at the moment of action. Yet she remained consistently on the side of the masses and shared their fate. That is to say, the unity of theory and practice was preserved in her actions with exactly the same consistency and with exactly the same logic as that which earned her the enmity of her murderers: the opportunists of Social Democracy."
