This paper approaches the entanglement in whic raises the scientific modernity, the liberalism and the classical political rationality. It is taken as a starting point the narrative of a life in a deserted island, as it is presented by the novel Robinson Crusoe, both in the original Defoe version and in Michel Tournier's recounting, aiming to discuss the ethical political implications of scientific work in the humanities more specifically in psychology, in the face of contemporary forms of resistance to capitalism, highlighting the possible rapports between the aesthetics of existence, as it was proposed by Michel Foucault, and the collective movements that are spreading around the world since 2012.
