 Géraud de Cordemoy (1626–1684) was one of the more important Cartesian philosophers during the decades immediately following the death of Descartes. While he is in some respects a very orthodox Cartesian, Cordemoy was the only Cartesian to embrace atomism, and one of the first to argue for occasionalism. Though a lawyer by profession, Cordemoy was a prominent figure in Parisian philosophical circles. His two most important works are Le Discernement du corps et de l’âme (1666) and his Discours physique de la parole (1668). In the former he defends atomism, mechanism, occasionalism, and dualism; the latter is a study of the nature of speech.
