This dissertation has as central aim to investigate the relationship between capitalism and subjectivity in the works of Gilles Deleuze, Félix Guattari, Antonio Negri and Michael Hardt. We start with the critical study of authors who think the relationship between capitalism and subjectivity in post-modernity, so as to understand the capitalist subjectivity in the contemporary world, according to these points of view. Next, we expose the thesis of Deleuze, Guattari, Negri and Hardt, investigating in which sense the thought constructed by these authors is capable of providing us the tools for the critique of oppression and affirmation of desire in the contemporary world. We search, in the philosophy of immanence, an ontology that thinks as immediate the relationship between subjectivity and politics, allowing us to comprehend desire as product and production, effect and cause, of social institutions. We find, in the works of these authors, the elements that connect subjectivity and politics inside a common constitutive horizon that entails both the affirmation of desire and the absolute destitution of any form of social sovereignty.
