Bas C. van Fraassen, in his Terry Lectures at Yale University, is concerned to elucidate what empiricism is, and could be, given past and current failures of characterization. He contends that naïve empiricism—the metaphilosophical position that characterizes empiricism in terms of a thesis—is self-refuting, and he offers a reductio ad absurdum to substantiate this claim. Moreover, in place of naïve empiricism, van Fraassen endorses stance empiricism: the metaphilosophical position that characterizes empiricism in terms of certain attitudes and commitments. The present (...) article, however, argues that van Fraassen begs the question in his reductio of naïve empiricism, and thus that his primary defense of stance empiricism is inadequate. (shrink)
