The project aims to trace what can be called a “genealogy” or “archeology” of the notion of therapy in the West. Following the lead of Friedrich Nietzsche and Michel Foucault, I will focus on the three paradigms or main configurations of therapy in Western culture: philosophy, religion and psychiatry. This “genealogy” or “archeology” entails two main parts. On the one hand, I will try to show the continuity and prevalence of the notion of therapy in Western culture, in any of these three main configurations, analyzing the similarities and differences between them, as well as an eventual common background. On the other hand, I will try to determine the impact, consequences and effects of the prevalence of therapy in Western culture, on an psychological, social, cultural and political level, trying to produce what in a Nietzschian/Foucauldian sense one could call a critique of its value.
