Abstract
By deepening Austin’s reflections on the ‘open texture’ of empirical concepts, Frederick L. Will defends an ‘externalist’ account of mental content: as human beings we could not think, were we not in fact cognizant of a natural world structured by events and objects with identifiable and repeatable similarities and differences. I explicate and defend Will’s insight by developing a parallel critique of Kant’s and Carnap’s rejections of realism, both of whom cannot account properly for the content of experience. This critique shows that Will has identified a genuinely transcendental basis for defending common-sense realism, without appeal to any high-level theory of knowledge. I then show how Will’s realism undercuts Simon Blackburn’s quasi-realism, Michael Williams’ partial defense of skepticism, John Haldane’s attempt to rehabilitate Aquinas’ account of concepts, and how it augments Crispin Wright’s defense of realism.
