In this article, we aim to show, by means of several examples, that Pierre Duhem's logical distinction operated by Pierre Duhem between physics and metaphysics does not prevent him, from a historical perspective, recognizing that there can be a fruitful interplay between the two fields of knowledge. We distinguish three possible levels of interaction that we believe Duhem accepts between physics and metaphysics: (a) that the physicist works constantly moved by metaphysical ambitions not authorized by rigorous logic; (b) that the metaphysical systems have contributed to the progress of many physical theories and, especially, to the birth of modern science, and; (c) that we can identify long-lasting metaphysical traditions of research which have shown themselves to be more fertile than the positivist traditions.
