 Here we have Cavendish indicating that (in at least some circumstanes) the various parts of nature are able to move as they please or as they will. But we do not yet know what it means for her to say that a body moves as it will. Perhaps Cavendish subscribes to a libertarian view of freedom according to which a creature is free when it possesses a two-way contra-causal ability to do otherwise. On such a view, an agent will always act in a certain way at a given moment, but at the time of action it is always possible for the agent to do otherwise. Or perhaps Cavendish subscribes to a compatibilist view of freedom according to which creatures do not possess a two-way ability to do otherwise, but their action is free in the sense that is due to their will alone, and is not encumbered by other causes.
