 The second and third inconveniens both deal with Descartes theory of the individuation of physical bodies. For Descartes, bodies are individuated in terms of motion: an individual body is that portion of matter which moves together, that is, which changes place with respect to the bodies which are its neighbors. Cordemoy’s first question is how, on this account, can we individuate a body at rest: “According to their doctrine, we cannot conceive of a body at rest between other bodies, because supposing that it is touching them, this doctrine teaches that together with them it makes only one body. Yet it seems to me that we have a very clear and very natural idea of a body perfectly at rest between other bodies, where nothing is in motion, and what I say of each body accords perfectly well with this idea” (1968, 99). It is, then, our clear conception of a body at rest between other bodies but at the same time distinct from them which signals trouble for the Cartesians theory. Cordemoy, on the other hand, faces no such problem, since for him the only true physical individuals are bodies/atoms; all other ‘bodies’ are rightly called matter, and are individuals only in a loose sense of the word.
