 McCann (2011) objects that Downing’s account accords undue epistemic weight to the natural line of thought in Essay 2.8. He maintains Locke’s reasoning is non-theoretical and unable to justify assent. Its force is limited to showing how “ordinary folks have to think” about the qualities ordinarily ascribed to bodies (McCann 2011: 184–6). The discussion has weight enough to overtop the common views about the resemblance of ideas of SQs to their causes, which is all Locke intends it to do (McCann 2011: 175, 171–2).
