El artículo saldrá publicado simultáneamente en Inglés y Portugués, The operation that we are interested in emphasizing revolves around these dimensions that are illuminated in the critical work of reading with cultural materials and that suppose a conceptual complementarity between the paths of biopolitics and precariousness. What these analyzes and their work with materials indicate, in a very clear way, is a set of dimensions, lines of inquiry and areas of problematization that do not acquire enough relevance in contemporary debates about biopolitics and precarity. Hence the need to develop a conceptual framework tool, which accounts for these markers that encode a precarious life. And precisely, that is the blind spot in common and at the same time, a space of conceptual intersection: the paths in biopolitics that have not considered the processes of precarization of life and in equal measure, the theorizations about the precarious condition that they have not thought about in strictly biopolitical terms. We call this conceptual knot: bíos-precarious. The bíos-precarious concept spawns from the conjunction between Judith Butler´s toolbox in relation to the bodily ontology of precariousness; and the crossing in Roberto Esposito´s biopolitical path between impersonal life and affirmative biopolitics.Revista indexada y resumida en: SciELO, Scopus -Elsevier Web of Science, DOAJ, (I2OR) Latindex, LivRe! - EZB -Worldcat, DRJI -RCAAP - SciLit -OALib - OAJI
