Can Skeptics Earn Their Keep?

This paper investigates the prospects for skepticism once we distinguish between bare skeptical theses and arguments and mature philosophical theory. If all skeptics have to offer is bare theses and arguments, skepticism presents only a challenge of reflective equilibrium. But if skeptics can move toward developed theory, then skeptics have, as I will put it, earned their keep. Just as foundationalism should be taken seriously in part because theory development goes well beyond a mere regress argument for the view, just so skepticism needs theory development to be taken seriously as well. The problem is that it is not clear that theory development is possible for skeptics. Here I articulate this concern and give some grounds for thinking that it can be overcome.
