ABSTRACT The purpose of this paper is to explore, based on theoretical propositions of the Bakhtin Circle, some relations between discourse and ideology, taking the scientific dissemination discourse of Ciência Hoje [Science Today] magazine as our object of investigation. Operating with the idea that the concrete utterance is the main locus of creation of ideology, we focus on two editorials of that magazine (one from the 1980s and the other from the 1990s), trying to show how ideological clashes of contemporary (...) society manifest in the architecture of those editorials.
