ABSTRACT Science fiction is a literary genre that has spread around the world due, among other reasons, to its popularity; narratives contain exotic characters and fantastic intrigue. It is considered by the circle of scholars and critics, however, a “minor” literature; for discourse linguists, its aesthetic attributes remain in the background. The theory of points of view (POV), for example, can contribute to a better assessment of the genre. This article aims to study this literary genre via enunciation. First, we (...) talk about studies in narratology to delimit the place of science fiction (or sf) in the universe of narratives. Secondly, we talk about concepts and notations from POV theory within narratological studies to trigger a dialogical analysis of literary discourse. Thirdly, we analyze a fragment from Dune, by Frank Herbert, in its version into Brazilian Portuguese (2017). Finally, we propose that “superpowers” held by characters in this genre can be explained linguistically. (shrink)
