 Thus Garber (1992, Chapter 6–8) proposes that Descartes actually took the unequivocal notion of motion properly speaking to be the correct sense of motion in mechanics. Then Rule I covers the case in which the two bodies have equal and opposite motions relative to their contiguous surroundings, while Rule VI covers the case in which the bodies have different motions relative to those surroundings – one is perhaps at rest in its surroundings. That is, exactly what is needed to make the rules consistent is the kind of privileged, true, sense of motion provided by Descartes’ second definition. Insurmountable problems with the rules remain, but rejecting the traditional interpretation and taking motion properly speaking seriously in Descartes’ philosophy clearly gives a more charitable reading.
