Abstract

The need to rethink the history of ideas has led both Kuhn and Foucault to break away from the prevalent conception of knowledge as one of continuous growth, of accretion. It is surprising how little attention philosophers and historians of science have paid to Foucault's work, and how, consequently, the convergence between his and the Kuhnian approach has gone completely unnoticed. To see the parallels, however, and to relate their works, promises to give rise to a synthesis that might present a new approach to the history of ideas (going beyond the particular concerns of our two authors). The present paper attempts a first step: It relates the key concepts of Kuhn and Foucault (“revolution/rupture; normal science/épistèmé”) and discusses the possibility of clarifying Kuhn's concept of normal science in the light of Foucault's analysis of discursive structures, and of adding Kuhn's explanation of the cause of conceptual change to the range of Foucault's tools. The last section is devoted to an evaluation of the author's relativism which is seen as a fertile notion and shown to be distinct from Feyerabend's brand of relativism.
