Antecedentes de algunos lineamientos de la estrategia de Aristóteles frente al negador del principio de no contradicción en el Sofista de Platón

Abstract

The purpose of this paper is to show that in the Sophist Plato develops a dialectical strategy that appeals to necessary conditions of language as a fundamental step toward establishing some principles of his ontology. This strategy constitutes a clear antecedent of the elenctic refutation offered by Aristotle in Metaphysics Gamma 4 against the denier of the principle of non-contradiction and could be described as transcendental because it refers to conditions without which there wouldn´t be any speech. The paper aims to show that such a strategy is used both by Plato and Aristotle to deal with radical adversaries whose refutation allows the establishment of basic theses of their own philosophies.
