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.

In this article I return to an argument that I presented in earlier work to the effect that virtue epistemology is at worse false and at best unmotivated. In the light of recent responses to this argument from such figures as John Greco, Guy Axtell, and Kelly Becker, I here re-state and re-evaluate this argument. In the process the original argument is refined and supplemented in key respects and some of the main charges against it are shown to be unfounded. Nevertheless, I also argue that at least one of the objections to the original argument—due to Becker—may well be on the right lines, and I draw some conclusions in this regard.

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.

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

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.

A certain conception of the relevance of virtue epistemology to the philosophy of education is set out. On this conception, while the epistemic goal of education might initially be promoting the pupil's cognitive success, it should ultimately move on to the development of the pupil's cognitive agency. A continuum of cognitive agency is described, on which it is ultimately cognitive achievement, and thus understanding, which is the epistemic goal of education. This is contrasted with a view on which knowledge is the epistemic goal

It is nowadays taken for granted that the core radical sceptical arguments all pivot upon the principle that the epistemic operator in question is 'closed' under known entailments. Accordingly, the standard anti-sceptical project now involves either denying closure or retaining closure by amending how one understands other elements of the sceptical argument. However, there are epistemic principles available to the sceptic which are logically weaker than closure but achieve the same result. Accordingly the contemporary debate fails to engage with the sceptical problem in its strongest form

In a recent, and influential, article, Crispin Wright maintains that a familiar form of scepticismwhich finds its core expression in Descartes’ dreaming argumentcan be defused (or, to use Wright’s own parlance, “imploded”), by showing how it employs self-defeating reasoning. I offer two fundamental reasons for rejecting Wright’s ‘implosion’ of scepticism. On the one hand, I argue that, even by Wright’s own lights, it is unclear whether there is a sceptical argument to implode in the first place. On the other, I claim that even on the supposition that Wright has indeed succeeded in setting-up such an argument, he nevertheless fails to follow-through with an adequate response. A diagnosis of the failure of Wright’s approach is then given in the context of the wider sceptical debate.

According to neo-classical economic theory, free markets should eventually settle at the most efficient equilibrium. Critics of the view have claimed, however, that even if the idealised conditions demanded by the theory were met (such that the markets in question were completely fee) one would still not find those markets settling at the optimally efficient equilibrium because of the path dependent' nature of economic decision-making. Essentially, the claim is that economic decision-making is always informed by the historical setting in such a way as to prevent those decisions from generally tending towards an optimally efficientequilibrium.It is argued that this debate has been hampered by the fact that the usual three-tiered way of understanding path dependence offered by Stan Liebowitz and Stephen Margolis fails to capture what proponents of the view have in mind. By examining the way in which the notion of path dependence is often described interms borrowed from the philosophy of science, this paper contends that we can gain a more accurate understanding of this notion by recasting it in the light of the Wittgensteinian conception of a 'hinge' proposition. This new account has the advantage of being clearer about the kind of empirical data that is relevant to the issue of whether path dependence is a genuine and economically significant phenomenon. Furthermore, it is argued that this modified account of path dependence may be able to resist some of the key objections that have been levelled against this notion.

The value of knowledge has always been a central topic within epistemology. Going all the way back to Plato’s Meno, philosophers have asked, why is knowledge more valuable than mere true belief? Interest in this question has grown in recent years, with theorists proposing a range of answers. But some reject the premise of the question and claim that the value of knowledge is ‘swamped’ by the value of true belief. And others argue that statuses other than knowledge, such as justification or understanding, are distinctively valuable. We will call the general question of why knowledge is valuable the value problem.
