Resumen: Con todo lo pretencioso que resulte el hacer una lectura propia de Platon y Aristoteles, debido a la cantidad de interpretaciones que sobre estos pensadores se ha hecho en la Historia, aqui lo intentare, logicamente, tomando 103 y el Libro III de la Politica de Aristoteles104 griegos, para luego compararlas y criticarlas; seguidamente, relacionare las conclusiones politicas de este analisis con las tesis del “Biopoder” Michael Foucault105 y con los postulados bioeticos de Gilbert Hottois. Palabras claves: Poder – Conocimiento, Etica, Poder, Naturaleza, Biopoder, Abstract: With everything that is pretentious to make their own reading of Plato and Aristotle, because of the number of interpretations of these thinkers have been done in history, here I’ll try, of course, taking only one aspect of his an explanation of the thesis and arguments of these two Greek philosophers, and then compare and criticize, then, will relate the political conclusions of this analysis with the thesis of “Biopower” Michael Foucault and the bioethical principles Gilbert Hottois. Keywords: Power – Knowledge, Ethics, Power, Nature, Biopower.
