This research offers a new interpretation of texts Karl Marx wrote in 1844, specifically the Economic and Philosophical Manuscripts (Ökonomisch-Philosophische Manuskripte) and the Paris Notebooks (Pariser Hefte). Its main objective is to show how the core ideas in these texts gain philosophical depth when understood through the concept Marx called “authentic appropriation” (wirkliche Aneignung). The result of this research reveals the original model Marx used to outline his proposal for the positive resolution of alienation (Entfremdung).
