Rosa Luxemburg
In one of her earliest publications, 'Reform or Revolution?' (1900) Luxemburg accepted Marx's argument that capitalism promoted exploitation and was at odds with humanity's natural, fraternal instincts. She also agreed that evolutionary socialism was impossible: only revolution could create real change. However, like Lenin, she had little sympathy for Marx's 'historicism' and denied that for a revolution to occur, capitalism would have to reach an advanced stage of development. However, Luxemburg's analysis of how the revolution should come would distinguish her from both Marx and Lenin.
