In his later work, he rejected Orthodox Marxism as historically outmoded, wanting to adapt Marxism to a new historical situation. He wrote in his "Ten Theses" (1950) that "the first step in re-establishing a revolutionary theory and practice consists in breaking with that Marxism which claims to monopolize revolutionary initiative as well as theoretical and practical direction" and that "today, all attempts to re-establish the Marxist doctrine as a whole in its original function as a theory of the working classes social revolution are reactionary utopias".
