  Kant's Laws of Mechanics have been discussed widely in the secondary literature. One can point to discussions by Palter (1972), Duncan (1984), Friedman (1989, 1992, and 1995), Brittan (1995), Westphal (1995), Carrier (2001), and Watkins (1997 and 1998b). Much of the modern tradition of scholarship used to regard Kant's laws of mechanics as derived from, or even identical with, Newton's three laws in the Principia. Watkins (1997; 1998b) showed that Kant's formulation and justification of his laws was strongly influenced by a philosophy of nature stemming from Leibniz not Newton. Stan (2013) further corroborated these findings. As a result, it is safe to say that Kant's foundations of mechanics were significantly shaped by post-Leibnizian rationalism too, not just Newton's mechanics. This fact is now reflected in Friedman (2013), the most recent and detailed account of Kant's interpretation of the conceptual foundations of mechanics. Stan (2014) examines the conceptual link between Kant's theory of matter and his laws of mechanics.
