Out of the chaos following Lenin's death and the mounting fury against Luk�cs and his freshly penned History and Class Consciousness (1923), this book bears an assessment of Lenin as "the only theoretical equal to Marx." Luk�cs shows, with unprecedented clarity, how Lenin's historical interventions-from his vanguard politics and repurposing of the state to his detection of a new, imperialist stage of capitalism-advanced the conjunction of theory and practice, class consciousness and class struggle. A postscript from 1967 reflects on how this picture of Lenin, which both shattered failed Marxism and preserved certain prejudices of its day, became even more inspirational after the oppressions of Stalin. Luk�cs's study remains indispensable to an understanding of the contemporary significance of Lenin's life and work.
