Discourse and Politics. Post-structuralist contributions in the work of Ernesto Laclau and Chantal Mouffe

The objective of the article is to analyze the link discourse and politics in the Post-structural Theory of Discourse (TPD) presented by Ernesto Laclau and Chantal Mouffe (1987) The analysis combines theoreticalpractical documentary research with deconstruction and critical reflection. The theoretical aspects come mainly from Saussure (1971), Laclau and Mouffe (1987), Laclau (1993, 2006), Mouffe (2007), Rojas (2014) and Fair (2015), among others. The article provides a way to deconstruct basic concepts to understand the discursive articulation. The conclusions are: 1) the TPD radicalizes the linguistic turn and the structural games of language in a redefinition of society contributed from the articulation discourse-hegemony-the political and the political, 2) The TPD based on the discursive hegemony as an actual articulation, between other, 3) the Derridian deconstruction taken up by Laclau and Mouffe in the TPD is basic to interpret the differences between types of democracy and States by the way they hegemonize the particular senses of the signifiers to naturalize them, through political struggle, as of universal validity
