 To some extent, the way in which Diderot’s philosophical work employs different genres but also, challenges the idea of genre itself, has made it seem (perhaps too easily) congenial to a more “Continental” philosophical tradition, and foreign to a more formally oriented “analytic” tradition. But that would ignore Diderot’s naturalistic commitments and the role the Encyclopédie played, e.g., in the self-image of philosophers of science in the Vienna Circle. Our entry seeks to go beyond such oppositions in dealing with Diderot as a philosopher.
