S'étonnant qu'un simple physicien sache traiter des rapports de la physique et de la métaphysique, Edmond Domet de Vorges s'était demandé si Pierre Duhem n'avait pas bénéficié de l'aide de quelque théologien dans l'élaboration de son articulation de ces deux disci­plines. Faisant suite à cette question très perti­nente, cet article liste d'abord les intellectuels catholiques qui étaient en relation avec Duhem avant la publication, en 1893, de son article Physique et métaphysique et qui auraient effec­tivement pu l'aider à concevoir une telle articulation. Se con­sacrant ensuite spécifiquement à l'un d'entre eux, à savoir Maurice Blondel, il étudie les similitudes et divergences existant entre les pensées du physicien bordelais et du philosophe d'Aix pour conclure que Blondel ne peut pas être celui qui aurait inspiré Duhem. À l'appui de cette conclusion, il fait notamment état d'une lettre inédite adressée par Duhem à Ambroise Gar­deil et dans laquelle celui-ci porte un jugement sévère à l'en­droit de son «pauvre ami» Blondel. ––– One might be surprised to find that a simple physician could be able explain with clarity the subtle relationship between physics and metaphysics. It is with this question in mind that Edmond Domet de Vorges asked himself if it might not have been with the aid of theologians that Pierre Duhem was able to find and express his subtle articulation between the two disciplines. Following in the footsteps of this pertinent question, this article begins by listing the catholic intellectuals who were acquain­tances of Pierre Duhem before the publication in 1893 of “Physique et métaphysique”, who may have been able to help him arrive at the relationship between the two sciences expressed in his publication. This line of questioning is followed by a specific study of one of these men, namely Maurice Blondel. The similarities and differences in the opinions of the physician from Bordeaux and the philosopher from Aix are explored with the resulting conclusion that Blondel could not have been he who inspired Duhem. This conclusion can be confirmed by a previously unpublished letter from Duhem to Ambroise Gardeil which contains a very severe judgement with regards to his “poor friend” Blondel.

Selon l’interprétation traditionnelle, la révolution copernicienne, qui opère le passage du géocentrisme à l’héliocentrisme, aurait détrôné et dévalorisé l’homme, en lui retirant sa position cen­trale, et donc privilégiée, dans le cosmos, pour le reléguer sur une planète devenue analogue aux autres et occupant une place quelconque à l’intérieur du système solaire. Cette inter­prétation ne pèche pas seulement dans sa compréhension de l’héliocentrisme copernicien, mais également dans sa percep­tion du géocentrisme aristotélico-médiéval. Il faut donc dénon­cer sa fausseté générale et, plus encore, lui substituer un autre schéma interprétatif qui, peut-être moins évocateur de notre rapport au monde, soit plus respectueux de la vérité historique. ––– According to the traditional interpretation, the Copernican revo­lution, which brought about the transfer from geocentrism to heliocentrism, is said to have dethroned and devalued man by removing his central and hence privileged position in the cos­mos and by relegating him to a planet now seen as analogous to others occupying an insignificant position within the solar system. This interpretation fails not only in its understanding of Copernican heliocentrism, but also in its percep­tion of Aristo­telian mediaeval geocentrism. It is necessary, therefore, not only to denounce its general falsity, but also to substitute for it a different interpretative scheme which, although it may empha­size less our link with the world, may be more respectful of historical truth.

This article starts, on the one hand, with a consideration of the paradoxical way in which, namely when he wanted to evoke those intellectual figures that have decidedly contributed to the revelation of the "true Pascal", i. e., of the Pascal that had known the good usage of reason, Fortunat Strowski comes to the idea of putting side by side Pierre Duhem and Leon Brunschvicg. On the other, a reference is made to the fact that Duhem only published two articles and a preface on Pascal while Brunschvicg is the author of a major work on the great figure of the XVIIth -Century. Hence, the question raised is about the consideration that shall be given to a paradoxical affirmation that seems to place on equal terms the few pages that Duhem has written on Pascal with the imposing contributions of Brunschvicg. For the author of the article, it would not be very consequent to take such affirmations as if they were unreflected ones, since it is clear that Strowski knew exactly what he was writing as we can see from the very good knowledge he had of the writings of both Blaise Pascal and Pierre Duhem. Indeed, and more than anyone else, Strowski was in a very good position to enlighten us about these two thinkers and to write about them in the terms he effectively did. The goal of the article, therefore, is to justify that assertion, which on its face is quite paradoxical, by showing in concrete terms the extent to which Pierre Duhem was truly influenced by Blaise Pascal. ––– O presente artigo começa por realçar o modo paradoxal como, uma vez que ele se dá ao trabalho de evocar aqueles autores que contribuíram para a revelação do verdadeiro Pascal, ou seja, daquele que conheceu o bom uso da razão, Fortunat Strowski não hesita em colocar o nome de Pierre Duhem lado a lado com o de Léon Brunschvicg. O facto, porém, é que Pierre Duhem não fez mais do que publicar dois artigos e um prefácio sobre Blaise Pascal, ao passo que Brunschvicg lhe dedicou uma obra que haveria de ficar famosa. O problema, portanto, consiste em saber qual o valor que se deve atribuir a uma tal afirmação desconcertante, a qual parece simplesmente equalizar as poucas páginas de Duhem sobre Pascal com as imponentes contribuições de Brunschvicg. Nesse sentido, a estratégia do autor do artigo consiste em não tomar de forma ligeira uma tal afirmação, como se Strowski não tivesse considerado bem as consequências e o alcance daquilo que escrevia, pois a verdade é que ele conhecia não só a obra de Pascal mas também a de Duhem. Ou seja, mais do que ninguém, ele estava perfeitamente à altura de nos comunicar algo de substancial acerca de cada um destes pensadores e de escrever a seu propósito aquilo que ele efectivamente escreveu. Em suma, o presente artigo não tem outra pretensão que não a de justificar essa afirmação aparentemente paradoxal segundo a qual Pierre Duhem foi um verdadeiro pascaliano.

Selon l’interprétation traditionnelle, la révolution copernicienne, en arrachant l’homme de sa position centrale dans le cosmos, lui a infligé une profonde vexation. Si elle dit bien notre désarroi contemporain face à un univers devenu infini, cette inter­pré­tation ne reflète pas suffisamment la complexité historique du passage du géocentrisme à l’héliocentrisme. Aussi convient-il de la remettre en question. Mais pour ce faire, il faut d’abord bien la connaître. Aussi cet article étudie-t-il la phase de structu­ration de cette interprétation (1835-1925), dans le contexte du positivisme, du darwinisme, du marxisme et enfin du freudisme. ––– Según la interpretación tradicional, la revolución copernicana, al sacar al hombre de su ubicación central en el cosmos, le propinó una profunda incomodidad. Esta interpretación corres­ponde a nuestra desazón actual provocada por un universo infinito pero desconoce la complejidad histórica implícita en el tránsito desde el geocentrismo al heliocentrismo. Por ello es necesario volver a plantear el problema, y para hacerlo hay que abordar correctamente el tema. De ahí que el presente artículo estudie el período de estructuración de esta interpretación (1835-1925) en los contextos del positivismo, del darwinismo, del marxismo y finalmente del freudismo.
