The most fundamental level on which Lukács develops his revised model of Hegelian Marxism is one of ontology, or, more specifically, of an “ontology of social being”. This ontology is intended, at least outwardly, to be a faithful interpretation of the ontological implications of Marxism. However, the way in which Lukács develops these ontological foundations—as well as his extended and sympathetic discussion of Nicolai Hartmann—betrays the way in which they function to support his own, Hegelian Marxism against dogmatic Historical Materialism (although, as Heller 1983 notes, not without a number of unsolved contradictions).
