Husserl desarrolla un enfoque genético que busca dar cuenta del origen de las formas lógico-categoriales a partir de las correspondientes preestructuraciones situadas en el nivel de la receptividad sensible. Para un enfoque de ese tipo, la explicación del origen de las modalidades del juicio, en general, y la negación, en particular, plantea peculiares desafíos. El presente trabajo discute el modo en el que Husserl trata la negación, en tanto forma básica de la modalidad, tanto en el enfoque estático de Ideen (...) I como en el enfoque genético de Erfahrung und Urteil. A fin de poner de relieve el al-cance histórico y sistemático de la concepción husserliana, se proporciona previamente una presentación general de su contexto polémico inmediato. Este viene dado por la oposición entre psicologismo y formalismo, dominante en la filosofía de la lógica alemana de fines del siglo XIX y comienzos del siglo XX.Husserl develops a genetic approach that seeks to account for the origin of the logical-categorical forms starting from the corresponding pre-structures located at the level of sensitive receptivity. For such an approach, the explanation of the origin of the modalities of judgment, in general, and negation, in particular, poses peculiar challenges. This paper discusses how Husserl treats negation as a basic form of modality, both in the static approach of Ideen I and the genetic approach of Erfahrung und Urteil. Previously, in order to highlight the historical and systematic significance of the Husserlian conception, a general presentation of its immediate polemic context is offered, especially with reference to the opposition between psychologism and formalism, dominant in the German philosophy of logic of the late nineteenth and early twentieth century.

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.
