This dissertation proposes a reflection on the published correspondence (1976-1981) of the poet Paulo Leminski (1944- 1989) and the cycle of biographies he produced from 1983 to 1986. In the literary-cultural context of the 1970s and 80s, Leminski carried out, by means of these two discursive practices, the deconstruction of hegemonic aesthetic and epistemological values. The reading of the letters included in Envie meu dicionário, edited by the poet Régis Bonvicino, Paulo Leminski s friend and correspondent, and the biographies in the volume Vida, covers Leminski s process of aesthetic-literary subjectivization. A hybrid process of textual construction resulting from negotiations between low, high and media matrices is apparent in the correspondence as well as in the biographies. The interpretation of the letters and the biographies also relies on other texts by Leminski - poems, newspaper columns, essays, reviews, articles, interviews - in a wide-ranging intertextual dialogue that takes on, in this thesis, the status of theory. The textual context of the correspondence and the biographies supports the relation between art and life, aesthetic project and political project, and offers material for a selfportrait of the writer and intellectual in the form of fragments.
