 The final of the six discourses which make up the Discernement addresses the question of the distinction between the mind and the body, as well as an argument that the existence of the mind is better known than the existence of the body (but note: not that the nature of the former is better known than the nature of the latter, as Descartes had claimed) and a glossary of the affects of the mind, the body, and the mind-body union. Cordemoy’s first argument for the distinction begins by listing a number of features of bodies, and contrasts this with a list of features of minds. Seeing that what is most fundamental to body is absent from the list of properties of the mind, and vice versa, he concludes that we thus “have reason to judge that they are two completely different things” (1968, 153).
