This dissertation uses as methodology the bibliographical research of authors of history, theory and political philosophy and of Freudian psychoanalysis read by Jacques Lacan. The research was carried out between 2018 and 2021 in Brazil and its objective is to combine psychoanalysis and politics in order to circumscribe a model of democracy that finds ground in the psychoanalytic theory of Lacanian reading. We will bring to our work the vision of Yannis Stavrakakis on Chantal Mouffe s politician, in his articulation with Lacan s concept of the real. The proposal joins the Mouffean project of a new model of radical democracy, contemplating constitutive impossibilities, articulated to the Lacanian real - impossible to be represented -, destabilizing the practices of conventional politics. As a response, instead of denying the inconsistencies of politics and buffering them with utopian ideals, it seeks to include this dimension of tension and fissure in democratic reality. The hypothesis of our argument is that political theory and Lacanian theory provide an outline for the understanding of democracy so that it can operate coherently, according to its contingencies. The conclusion of our dissertation is that the theoretical framework used in the extension of the work meets the objective of providing another perspective of democracy. We emphasize, however, that the global economic factor, not explored in our writing, transcends territorial limits and directly involves local politics, making it difficult for a new conception of democracy, even if implemented, to survive, as it is strongly influenced by external factors.
