 This suggests that it is Newton’s Rule II that Hume considers to be “Newton’s chief rule of philosophizing”—an interpretation that fits well with what Hume writes about method in both the Treatise and in his later writings. It also reinforces the view that Hume rejects Rule III as being that part of Newton’s philosophy that is worthy of being adopted and imitated. Indeed, Hume’s point is precisely that it is Newton’s Rule II, chiefly, that we should be interested in. Rule III, with its extravagant claims concerning the presence of supposedly essential qualities in every body in the universe far from common life is one we can afford to set aside. The view we have presented here is at odds with that of Graciela de Pierris, who builds her discussion of Hume’s debt to Newton around Hume’s putative embrace of Newton’s Rule III as the cornerstone for his philosophical method (de Pierris 2006: 306–310, 312; for detailed criticism see Hazony &amp; Schliesser 2016).
