Eugene Dupreel and Chaim Perelman: the normative and critical principles of the “rhetorical turn” in contemporary philosophy. Part II

Abstract

The purpose of the article is, firstly, to explicate and give a critical assessment of the methodological, epistemological, and philosophical foundations that led to the “rhetorical turn” in modern philosophy, and, secondly, to answer the question of how justified the grounds for such a “rhetorical turn” are. The answer proposed is based on a reconstruction of Eugene Dupréel’s critical arguments that were directed against the “classical philosophy” and their reception in Chaim Perelman’s works during his “turning point” period (1947 – 1949). The article proves that these two scholars’ critique of classical philosophy proceeds from a realistic position, therefore it does not apply to the epistemological principles of idealistic philosophy. Their criticism of the classical theory of progress and the ideal of universally valid knowledge is “axiological” in nature and boils down to a reassessment of all traditional values. As a result of this reassessment, the methodological principles of sophistry (subjectivism, pragmatism, pluralism, relativism, conventionalism, etc.) are actually rehabilitated. The criticism of philosophy that appeals to spoken language and everyday knowledge, is not justified, since it is based on a misunderstanding of the conceptual and constructive nature of the philosophical language. Although the rhetorical analysis of philosophical texts should be recognized as fruitful and useful, rhetoric cannot be an instrument of philosophizing, since the interpretation of values depends on their understanding, which is given by “classical philosophy”.
