La thématique de la coopération entre la penséede Moses Hess et celle de Karl Marx (1844-1846)

This article purports to analyze Hess’ and early Marx’s thought on the question of “cooperation”. The latter gathered momentum with the publication of the essay On the Essence of Money. The concept of generic essence then came to stand second to the notions of productive vital activity, of generic action and of cooperation. References to cooperation make Marx’s philosophical and political trajectory visible. The notion of Zusammenwirken is indeed one of the conceptual tools through which Marx transformed Feuerbach’s philosophy to such an extent that he forsook the philosophical parlance linked to the concept of generic essence. Their intellectual synergy was followed by a definitive split which nonetheless still revealed the marks of their strife.
