 The obvious concern about this sort of defense (in both its particular and general form) is the fact that it necessarily involves epistemic circularity of some kind. That is, it defends the appeal to intuitions as reasons for belief by appeal to intuitions. It seems clear that epistemically circular defenses are sometimes illegitimate, as when questions about the epistemic probity of appeals to a crystal ball are answered by consulting the ball. However, as indicated above  (§3.2),  it also appears that some sort of epistemic circularity is inevitable in the attempt to defend our most basic modes of evidence and justification. Exactly when such circularity is epistemically disabling and when, if ever, it is acceptable is a difficult question which cannot be here treated in detail (Alston 1986, 1993; Bergmann 2006; Cohen 2002; Vogel 2008). However, a few remarks are in order.
