The recent movement towards virtue–theoretic treatments of epistemological concepts can be understood in terms of the desire to eliminate epistemic luck. Significantly, however, it is argued that the two main varieties of virtue epistemology are responding to different types of epistemic luck. In particular, whilst proponents of reliabilism–based virtue theories have been focusing on the problem of what I call “veritic” epistemic luck, non–reliabilism–based virtue theories have instead been concerned with a very different type of epistemic luck, what I call “reflective” epistemic luck. It is argued that, prima facie at least, both forms of epistemic luck need to be responded to by any adequate epistemological theory. The problem, however, is that one can best eliminate veritic epistemic luck by adducing a so–called safety–based epistemological theory that need not be allied to a virtue–based account, and there is no fully adequate way of eliminating reflective epistemic luck. I thus conclude that this raises a fundamental difficulty for virtue–based epistemological theories, on either construal. [ABSTRACT FROM AUTHOR].

A popular form of virtue epistemology—defended by such figures as Ernest Sosa, Linda Zagzebski and John Greco—holds that knowledge can be exclusively understood in virtue-theoretic terms. In particular, it holds that there isn't any need for an additional epistemic condition to deal with the problem posed by knowledge-undermining epistemic luck. It is argued that the sustainability of such a proposal is called into question by the possibility of epistemic twin earth cases. In particular, it is argued that such cases demonstrate the need for virtue-theoretic accounts of knowledge to appeal to an independent epistemic condition which excludes knowledge-undermining epistemic luck

A critique of attributer contextualist treatments of the problem of radical scepticism is offered. It is argued that while such proposals, standardly conceived, gain some purchase against the closure-based formulation of this problem, they run aground when applied to the logically distinct underdetermination-based formulation. A specific kind of attributer contextualism—rational support contextualism—is then explored. This is better placed to deal with underdetermination-based radical scepticism via its endorsement of ascriptions of factive rational support in everyday contexts of epistemic appraisal. But such a proposal is faced with a dialectical impasse with regard to the competing epistemological disjunctivist response to radical scepticism. While the former has dialectical advantages over the latter with regard to closure-based radical scepticism, the latter has the dialectical upper-hand when it comes to underdetermination-based radical scepticism. It is claimed that the way to resolve this issue—and thereby to understand that we should not expect a unified treatment of these two formulations of the sceptical problem, much less one that is cast along contextualist lines—is to recognise how these two formulations reflect distinct sources of scepticism.

Our interest is in the possibility of there being a philosophically interesting set of useful false beliefs where the utility in question is specifically epistemic. As we will see, it is hard to delineate plausible candidates in this regard, though several are promising at first blush. We begin with the kind of strictly false claims that are said to be often involved in good scientific practice, such as through the use of idealisations and fictions. The problem is that it is difficult to see that there would be any epistemic utility in believing such claims, as opposed, say, to merely accepting them. Next we turn to the challenge posed by epistemic situationism, which when embedded within a plausible form of virtue epistemology appears to show that sometimes purely situational factors can play a significant explanatory role in one’s cognitive success. But again it is hard to see how the role that these epistemically beneficial situational factors contribute can be cashed out in terms of epistemically useful false beliefs on the part of the subject. Finally, we turn to the Wittgensteinian conception of hinge commitments, commitments that are held to be epistemically useful even if false. While the epistemic utility of these commitments is defended, it is argued that one cannot make sense of these commitments in terms of belief. Support is thus canvassed, albeit in a piecemeal fashion, for the thesis that the prospects for there being philosophically interesting cases of epistemically useful false belief are poor.

Perhaps the most dominant anti-sceptical proposal in the recent literatureadvanced by such figures as Stewart Cohen, Keith DeRose and David Lewisis the contextualist response to radical scepticism. Central to the contextualist thesis is the claim that, unlike other non-contextualist anti-sceptical theories, contextualism offers a dissolution of the sceptical paradox that respects our common sense epistemological intuitions. Taking DeRose’s view as representative of the contextualist position, it is argued that instead of offering us an intuitive response to scepticism, contextualism is actually committed to a revisionist stance as regards our everyday usage of epistemic terms. In particular, it is argued that the thesis fails to present a satisfactory explication of a notionthat of ‘epistemic descent’that is pivotal to the anti-sceptical import of the account. On the positive side, however, it is claimed that although the contextualist response to scepticism is ultimately unsatisfying, DeRose’s theory does contain within it the framework for a completely differentand far more persuasiveaccount of the ‘phenomenology’ of scepticism which runs along noncontextualist lines.
