 Here Cudworth is pointing out, and Cavendish will agree, that we do not account for the orderly behavior of bodies by positing laws of nature if we do not know what a law of nature is or how it operates. On Cudworth’s view, the orderly behavior of bodies is secured by immaterial minds (or plastic natures) that attach to bodies and work to keep them on the rails. In something like the way that our (immaterial) minds intelligently guide our bodies, plastic natures intelligently guide the bodies that compose the plant and animal and mineral world. Cavendish agrees with a [highly modified] version of this last statement. She will raise the objection, though, that minds that move and come into contact with and attach to bodies must be material themselves.
