What do I mean by Marxism?

In a concise lecture, Alain Badiou presents his understanding of Marxism, giving a new profile to his own philosophy. Based on his personal relationship to Marxism, Alain Badiou outlines his sources and developments. In doing so, he shifts a number of Marxist concepts by placing the emphasis of his analysis on the class struggle and the recognition of class interests. In this way, a definition of Marxism emerges that defines it as "thinking of the transformation of knowledge into action" and escapes the difficulties associated with the definition of Marxism as science or politics. Finally, with the question of Marxism, Badiou also poses the great question of modernity: if capitalism has won (for the time being) primarily because it knew how to equate itself with modernity, how can it come.
