Critique of Political Economy and Relations of Forces in Gramsci's "return to Marx"

This article focuses on the role played by the critique of political economy and Marxian philosophy in the redefinition of Gramsci's political philosophy during his intellectual moment known as the "return to Marx''. On the one hand, we show the theoretical importance of the concept of mercato determinato in the formation of notions such as "civil society" and "relations of forces". On the other hand, the Italian philosopher's prison revisitation of some of Marx's works are evaluated; as well as its effects on the revision of certain topics such as the relationship between structure-superstructure or the theory of hegemony. Through an original interpretation of the critique of political economy; and also re-examining the theoretical principles of "historical materialism" in a "philosophy of praxis", the final aim is to present an interpretation of Gramscian social ontology able to provide a theory on the genesis, reproduction and crisis of a given social formation.
