Our main goal in this thesis is to study the political implications of two lines of thought and they differences. The first is the one that goes, thought the philosophy of Gilles Deleuze to the works of Toni Negri, and the second, thought the psychoanalysis of Jacques Lacan to the philosophy of Slavoj Zizek. In Deleuze, we seek to trace the contours of the philosophy of difference created by the author. Our next move is to analyze the proposition of a new political theory that was undertaken by the author in the 70s along with Félix Guattari. In the case of Lacan, our focus will be on political consequences of the movement in which the psychoanalyst, in the 60s, moves away from the symbolic and structuralist paradigm that had formed the basis of his theory in the 50s. And in Antonio Negri and Slavoj Zizek we find two of the most important philosophers who are currently responsible for continuing the line of thought that was inaugurated by Deleuze, in the case of Negri, and Lacan, in the case of Zizek.
