Problemas de Método na Ética Aristotélica.

Abstract

I investigate what method of proof and justification Aristotle adopts in ethics, the dialectical method, whose procedure is based in the analysis of endoxa, opinions justified only by reputability, the scientific method, whose syllogism is purely deductive in the manner of a mathematical demonstration, because its premisses are justified exclusively by truth, they are necessarily true, what warrant the truth of conclusion, or various different procedures and strategies ad hoc. I discuss if practical knowledge is necessarily inexact by the reason of the particular nature of human action. I claim that Aristotle uses both dialectical and scientific procedures on ethics, because did not systematically formulate an ethical method of investigation specifically and also that the practical knowledge is inexact by the nature of human action always performed into undetermined circunstances.
