This article presents an overview of Ernesto Laclau’s theory of hegemony from his first work as co-author with Chantal Mouffe of Hegemony and Socialist Strategy: Towards a Radical Democratic Politics (1985) to his last work On Populist Reason (2005). To that end, this corpus is analyzed with theoretical tools from Lacanian psychoanalysis in order to locate the implicit postulates in Laclau’s work and to organize his work into three main stages. We propose an interpretation of such theory from a psychoanalytic (...) perspective through three key concepts: antagonism, dislocation, and heterogeneity. (shrink)
