G. E. Moore famously offered a strikingly straightforward response to the radical sceptic which simply consisted of the claim that one could know, on the basis of one's knowledge that one has hands, that there exists an external world. In general, the Moorean response to scepticism maintains that we can know the denials of sceptical hypotheses on the basis of our knowledge of everyday propositions. In the recent literature two proposals have been put forward to try to accommodate, to varying extents, this Moorean thesis. On the one hand, there are those who endorse an externalist version of contextualism, such as Keith DeRose, who have claimed that there must be some contexts in which Moore is right. More radically still, Ernest Sosa has expanded on this externalist thesis by arguing that, contra DeRose's contextualism, Moore may be right in all contexts. In this paper I evaluate these claims and argue that, suitably modified, one can resurrect the main elements of the Moorean anti-sceptical thesis.

We offer an overview of what we take to be the main themes in Annalisa Coliva’s book, Moore and Wittgenstein: Scepticism, Certainty and Common Sense. In particular, we focus on the ‘framework reading’ that she offers of Wittgenstein’s On Certainty and its anti-sceptical implications. While broadly agreeing with the proposal that Coliva puts forward on this score, we do suggest one important supplementation to the view—viz., that this way of dealing with radical scepticism needs to be augmented with an account of the meta-sceptical problem which this proposal generates, which we call epistemic vertigo.

There are parallels between certain responses to local epistemological scepticism about religious belief and an influential reply to radical epistemological scepticism. What ties both accounts together is that they utilise, either implicitly or explicitly, a “hinge” proposition thesis which maintains that the pivotal beliefs in question are immune to sceptical attack even though they lack sufficient epistemic grounds. It is argued that just as this strategy lacks any anti-sceptical efficacy in the context of the radical sceptical debate, so it offers no defence against a localised scepticism regarding religious belief either. What the defender of religious belief should do, it is claimed, is re-examine the manner in which a commitment to the doctrine of epistemological internalism underlies the sceptical attack.

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].

I argue that the notion of reflective epistemic luck raises important questions about the centrality to epistemology of a conception of justification that demands that one is able to take cognitive responsibility for one’s beliefs. I take a critical look at some of the recent ‘virtue epistemologies’ that have been put forward in the recent literature which define knowledge in terms of the epistemic virtues and cognitive faculties. More specifically, I contrast broadly externalist construals of the virtue-theoretic thesis—such as the ‘agent reliabilism’ advanced, for example, by Ernest Sosa and John Greco—with virtue epistemologies that roughly fall into the internalist camp—in particular, ‘neo-Aristotelian’ theories, such as the view defended by Linda Zagzebski. I claim that in each case a key part of the motivation for offering such a view lies in a desire to eliminate a species of epistemic luck that is thought to be left uneliminated by rival theories of knowledge. In general, I claim that externalists and internalists in epistemology often speak past one another precisely because they are concerned with these different types of epistemic luck, and that disambiguating the species of epistemic luck at issue in this debate can help us to find a way of reconciling both internalist and externalist intuitions about knowledge. I conclude by arguing that once the ambiguous role of epistemic luck in the development of these virtue epistemological theories is made explicit, then the motivation to offer a specifically virtue-theoretic theory of knowledge subsides.

This essay offers a rearticulation and defence of the modal account of luck that the author developed in earlier work . In particular, the proposal is situated within a certain methodology, a component of which is paying due attention to the cognitive science literature on luck ascriptions. It is shown that with the modal account of luck properly articulated it can adequately deal with some of the problems that have recently been offered against it, and that the view has a number of attractions over competing proposals, such as the lack of control account
