  One approach to the tension is to understand it as a genuine inconsistency. Margaret Wilson has defended such an interpretation, though in the 1979 paper that launched the debate, her intent is to show how acutely Locke understood the explanatory limitations of “Boylean mechanism”. Specifically, Wilson argues, the inconsistency reveals Locke’s recognition “that some presumed properties of matter cannot be conceived as ‘natural’ consequences of Boylean primary qualities” (Wilson 1979, p. 197). Thus our ignorance about bodies has more profound causes than our ignorance about the primary qualities of a body’s constituent corpuscles. In accordance with her view that Locke’s agnostic tendencies (just like his dogmatic ones) are genuine, Wilson interprets Locke’s concept of superaddition robustly, as a sort of divine action that goes beyond the corpuscular hypothesis. According to this “non-essentialist” or “divine annexation” reading, Locke understands superadded properties as properties that God has annexed to matter by fiat, and that bear no intrinsic connection to matter’s real essence. This reading implies a distinction in etiology for superadded qualities. Whereas the other qualities of matter are either given initially, as those qualities constituting the real essence, or else flow from the real essence, superadded qualities are added on after the fact, such that the substance could have been complete without them.
