Hegemony, performativity and social change On the reintroduction of the temporality in theoretical proposals of Judith Butler and Ernesto Laclau

A really critical social theory which helps to generate knowledge directed towards the possible transformation of 'the instituted', means approach both the forms of social order's reproduction as their dimensions of openness to transformation. Focusing on the second dimension, we highlight the centrality of the notion of iteration in E. Laclau and J. Butler, understanding that this concept enable recognize how every structure is the result of a continuous and repeated installation, unconsolidated once and for all but deeply contingent. To account for this, we develop some relevant aspects of the Laclau's theory of hegemony while we work some dimensions of the Butler's construction around the notion of performativity. Thus, we try to show how the proposals of both authors, beyond some differences, share the reintroduction of the historical and contingent dimension of the social, which allows generate a vision of politics centered on the possibilities of a transformative agency embodied in historically constructed political subjects.
