The theoretical horizon of the Political Analysis of Discourse (APD) affirms the political ontology of all identity, from a particular conception of language, of social discourses and of the subject. By postulating the ultimate impossibility of the society as a meaningful totality fully and stably articulated, this transdisciplinary perspective investigates the conflict inherent in the historicity and contingency of any identity process, analyzing the struggles for hegemony around differences and antagonisms in the social space. The APD incorporates conceptual tools from different fields of knowledge (such as post-structuralist linguistics, post-Marxist political theory, Lacanian psychoanalysis and philosophical thinking of deconstruction). In this paper we present a review and assessment of its main contributions to social analysis in Latin America, as it constitutes a particular epistemological elaboration to address the political-discursive dimension of disputes over hegemony and social meaning.
