 (3) Broadly similar remarks have been suggested in reply to the objection that Quine’s response to skepticism is unsatisfactory. While that response may involve blatant circularity, for the reasons just given it’s an open question whether that circularity is vicious. Further, Quine claims, in pointing out that skeptical doubts are scientific doubts, he did not take himself to be refuting the skeptic or subjecting skepticism to a reductio (1975: 68). More generally, questions might be raised about the underlying assumption that responding to the skeptic in such a way as to not beg any questions is an achievable end to begin with, and so whether it is something that deserves as much attention as it has traditionally been afforded. Here, proponents of NE diverge somewhat. Kornblith states that the project of responding to the skeptic is “a dead end” (1999: 166). In a similar vein, Kitcher says that “[s]keptics who insist that we begin from no assumptions are inviting us to play a mug’s game” (1993: 35). Dretske (1970, 1981) is more conciliatory, offering an explanation that grants certain skeptical claims their power, even correctness, while defending our knowledge nonetheless. And both Goldman (1986: 39–41, 55–57; 1976: 101) and Pollock (1986: 1–7) take it to be a task of epistemology to address skepticism—even if our goal therein is to understand and learn from skepticism rather than to refute it, and even if the topic deserves less attention than it has historically received.
