Radical exclusions,empty signifiers and an anti-war genre

Ernesto Laclau argues that Saussurean structural linguistics is one framework necessary for a post-Marxist understanding of political identities and new social movements. Disrupting the distinction between the discursive and the political, he provides insight into the formal properties of identity, difference, universality and particularity. However, this disruption means that his work is relevant not only to political theory per se but has retroactive value for understanding semiotics and signification. By considering methodological problems encountered during an analysis of an anti-war poster genre, this essay suggests that Laclau's concept of empty signifiers enables a novel understanding of genre. His schema complements approaches that emphasize the analysis of content and the analysis of audience reception, broadly conceived. Between the poles of content and reception, there are structural or relational properties enabling the contingent stability and meaningfulness of genre. These properties include the differential nature of a genre's identity, and a genre's discursive reliance on a radical exclusion.
