La pluralità di Cartesio. Su soggettività e politica nel secondo dopoguerra: Heidegger, Sartre, Merleau-Ponty,

Is the Cartesian subject the foundation that ensures the entity by making it certain, as Heidegger would have it? Or is it a foundation only as a creative and productive activity, as Sartre suggests? Or, then again, is it a chiasm, a relationship, a view that Merleau-Ponty seems to favour? By directing their gaze towards the different facets of what Paul Valery had defined as “Descartes’ plurality”, Heidegger, Sartre and Merleau-Ponty would arrive, starting from the Second World War, at a conception of action as the bringing to completion of the relationship of being to man, as an active transformation of reality, or as the immersion of oneself in the complex plots of the world.
