 Thus, a more likely interpretation is that Hume believes he has offered a prescriptive interpretation of how Newtonian philosophy should be viewed in light of the results of his “science of man” (which shows the limitations of our cognitive capacity), and his restrictive form of Empiricism which contribute to his “modest” (or “mitigated”) skepticism. Hume may well have thought himself as an internal critic or “cautious Newtonian”. For Hume and Newton both appeal to the authority of experience. Nevertheless, the “copy principle” guides how Hume believes how “experiment” or “experience”—authoritative for Newton as well as Hume—should be analyzed. This may be why Hume claims that Boyle and Newton have shown the road to the “true philosophy”, not that they completed it. One way to understand Hume’s “science of man” is to see it, then, as the fulfillment of the Newtonian philosophy, “rightly understood”, that is, by Hume.
