From System into Action, from Homogeneous to Heterogeneous: Movements of the Founding Concepts of Dialogism, Polyphony and Interdiscourse

Abstract

Although originally based on a homogeneous perspective of language and, consequently, of the utterance and subjects – the discursive studies have developed toward the recognition of a discourse founding heterogeneity, which is able to support concepts such as dialogism, polyphony and interdiscursivity. This article intends to present this evolution through a brief theoretical retrospective, that covers the Speech Acts by Austin, as well as the constitutive heterogeneity of Authier- Revuz, the dialogism of Bakhtin and also through the polyphony of Oswald Ducrot. Derived from this turning point of the discursive studies, these concepts are considered by means of a wider reflection, which understands the institution of the heterogeneous discourse as its foundation.
