Pierre Duhem et la revendication d’une tradition phénoménaliste: à propos de son «Essai sur la notion de théorie physique de Platon à Galilée»

According to our interpretation, Σῴζειν τὰ φαινóμενα : Essai sur la notion de théorie physique pursues two intricately intertwined objectives. Primarily, it aims to establish the historical significance of Duhemian phenomenalism — the accuracy of which had previously been established in La Théorie Physique : son Objet et sa Structure — firstly, by positioning it within a millenary tradition and, secondly, by examining the conse­quences, both positive and negative, that subsequently arose from the various ways of comprehending the idea of physical theory. Secondarily, it proffers a novel interpretation of the rationale behind the Galileo affair, from a point of view which is both philosophical (that of the Duhemian epistemology as it had already been developed in The Aim and Structure of Physical Theory) and historical (that of the lessons resulting from historical considerations in To Save the Phenomena). This article is dedicated to establishing the existence of the first goal by examining, firstly, whether or not it had actually been sought out by Duhem himself, and, secondly, whether or not he believed he had achieved it.
