Abstract
This paper attempts to provide a concise but systematic presentation of the discursive ontology of the social that underpins the thought of the Argentinian political theorist Ernesto Laclau. First articulated by Laclau and his collaborator Chantal Mouffe at the historical conjuncture of the late twentieth century that witnessed the disintegration of established leftist political visions and the rise of a plurality of new social movements, the post-structuralist discursive ontology on which Laclau bases his theorization of hegemony as the paradigm of politics is one that continues to exert a powerful influence on contemporary post-foundational political thought, discourse analysis, and “left populist” political movements. This paper traces the fundamental claims of that ontology, paying special attention to Laclau’s theses apropos the limits of universality and impossibility of “fullness.” In the final third of this paper, the French philosopher Alain Badiou’s approach to the conceptualization of social change is employed as a foil to draw some key implications of Laclau’s elevation of “hegemony” as the universal form of the political for political thought and practice.
