This work - made up of three complementary philosophical essays - aims, based on Michel Foucault, but also Deleuze and other philosophers, to create a possible fold between subjectivity and freedom, with a specific purpose: to resist biopower. First, however, we intend to present the historical production of subjectivity and the deconstruction of the substantial subject, based on what Foucault called 'subjectivation'. Next, we intend to present biopower as a technology of government or device, and also as a component of subjectivation, in other words, as a constitutive force of the self, especially in the present day. Finally, the aim is to present a political spirituality, a way of doing politics with oneself in order to resist biopower. In short, a fold between subjectivation and freedom against biopolitical normalisation.
