Orthodox Marxism
In the essay "What is Orthodox Marxism?", Lukács argues that methodology is what distinguishes Marxism: even if all its substantive propositions were rejected, it would remain valid because of its distinctive method. According to Lukács, "Orthodox Marxism, therefore, does not imply the uncritical acceptance of the results of Marx’s investigations. It is not the ‘belief’ in this or that thesis, nor the exegesis of a ‘sacred’ book. On the contrary, orthodoxy refers exclusively to method. It is the scientific conviction that dialectical materialism is the road to truth and that its methods can be developed, expanded and deepened only along the lines laid down by its founders."
