methodically as they do" (OEP 139), and had argued similarly in the Philosophical Letters.24 As we have seen, she would go on to state the argument at greater length in the Ground. The regularity argument for Cavendish's view clearly was present in the texts of the 1660s, but plays a relatively small role in them. This small role in those texts suggests that the argument was not, in Cavendish's mind, the central justification for the view. That, plus the fact that the argument assumes a greater role as time goes on, suggests that thinking about how to explain regularity was also not a main part of Cavendish's motivation for her view. Cavendish aimed, in the 1660s, to develop something that looks like a serious system of natural philosophy.Causation in the Natural Philosophy of Margaret Cavendish."
