TY - BOOK AU - Daou,Marie TI - Back to Conventionalist Sources of the Epistemology of Economist Engineer Jacques Rueff PY - 2022///. N1 - 5 N2 - This paper focuses on Jacques Rueff’s connection with French conventionalists. His first academic piece, Des sciences physiques aux sciences morales (1922) is an epistemological book based on the unification of moral and physical sciences using a shared scientific methodology drawn from conventionalist principles. Indeed, Rueff extends and complements them by going beyond the exclusive scope of physical sciences. His goal is then to reconcile moral sciences – in particular political economy – with physical sciences, considering that “all sciences [including moral sciences] are rational” (Rueff 1922, 4).JEL Codes: B22, B23, B41 UR - https://shs.cairn.info/journal-revue-de-philosophie-economique-2021-2-page-3?lang=en&redirect-ssocas=7080 ER -
