Pressuposição linguística e artigo de opinião: uma relação necessária.

Abstract

This paper investigates the linguistic presupposition, a phenomenon of a semantic scope that accounts for the recovery of implicit meanings from the structure of the utterance itself. Initially revealed by the logician Gottlob Frege (1892), through a formal-logic semantics approach, and later developed by the semanticist Oswald Ducrot (1977), already based in Saussurean structuralism, in Ducrot‘s view, the presupposition is assumed as an argumentative strategy. The aim of this paper is to demonstrate, in a qualitative-descriptive approach, a necessary relationship between the argumentation in the opinion article genre and the phenomenon in focus. After tracing a historical and conceptual overview on presupposition, some of the lexical elements and syntactic behavior are enumerated, those which point out to the existence of implicit contents considered as presupposition. This research takes place in text genre of opinion article, due to its essentially argumentative aspect and its possibility of providing greater freedom to the writer in his/her argumentation. To accomplish that, an approach from the perspective of text genre is brought to light, according to definitions of Bakhtin (1992), Marcuschi (2002), Bazerman (2005) and Schneuwly (2004), and reflections of Rodrigues (2001), Melo (2003) and Silva (2008) on the genre in focus. By identifying the main presuppositions and their relations with argumentativeness, an analysis of texts is developed.
