Two of the main forms of anti-scepticism in the contemporary literature—namely, neo-Mooreanism and attributer contextualism—share a common claim, which is that we are, contra the sceptic, able to know the denials of sceptical hypotheses. This paper begins by surveying the relative merits of these views when it comes to dealing with the standard closure-based formulation of the sceptical problem that is focussed on the possession of knowledge. It is argued, however, that it is not enough to simply deal with this version of the sceptical challenge, since there is a more fundamental sceptical problem underlying the standard closure-based sceptical argument that can be expressed in terms of the evidential basis of our beliefs. Whilst it is argued that neo-Mooreanism has a slight edge over attributer contextualism when it comes to dealing with the closure-based formulation of the sceptical problem, it is claimed that this view is in an ever stronger dialectical position when it comes to the more pressing evidential formulation of the sceptical problem. It is shown that this is so even if one adapts the attributer contextualist thesis along the lines suggested by Michael Williams and Ram Neta so that it is explicitly designed to deal with the evidential variant of the sceptical problem.

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 avail- able 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.

An overview of the import of disjunctivism to the problem of radical scepticism is offered. In particular, the disjunctivist account of perceptual experience is set out, along with the manner in which it intersects with related positions such as naïve realism and intentionalism, and it is shown how this account can be used to a motivate an anti-sceptical proposal. In addition, a variety of disjunctivism known as epistemological disjunctivism is described, and it is explained how this proposal offers a further way of responding to radical scepticism.

One of the key supposed 'platitudes' of contemporary epistemology is the claim that knowledge excludes luck. One can see the attraction of such a claim, in that knowledge is something that one can take credit for - it is an achievement of sorts - and yet luck undermines genuine achievement. The problem, however, is that luck seems to be an all-pervasive feature of our epistemic enterprises, which tempts us to think that either scepticism is true and that we don't know very much, or else that luck is compatible with knowledge after all. In this book, Duncan Pritchard argues that we do not need to choose between these two austere alternatives, since a closer examination of what is involved in the notion of epistemic luck reveals varieties of luck that are compatible with knowledge possession and varieties that aren't. Moreover, Pritchard shows that a more nuanced understanding of the relationship between luck and knowledge can cast light on many of the most central topics in contemporary epistemology. These topics include: the externalism/internalism distinction; virtue epistemology; the problem of scepticism; metaepistemological scepticism; modal epistemology; and the problem of moral luck. All epistemologists will need to come to terms with Pritchard's original and incisive contribution.

A very natural view about perceptual knowledge is articulated, one on which perceptual knowledge is closely related to perceptual discrimination, and which fits well with a relevant alternatives account of knowledge. It is shown that this kind of proposal faces a problem, and various options for resolving this difficulty are explored. In light of this discussion, a two-tiered relevant alternatives account of perceptual knowledge is offered which avoids the closure problem. It is further shown how this proposal can: accommodate our intuitions about perceptual knowledge and perceptual discrimination in terms of the notion of primary relevance, give an account of how alternatives can be rationally excluded without appeal to perceptual discrimination in terms of the notion of secondary relevance, and deal with the problem posed by inverted Gettier cases, and hence explain what it means to rationally exclude alternatives which are of secondary relevance

ABSTRACT: Perhaps the most influential proposal in the recent literature on the epis- temology of religious belief has been Alvin Plantinga’s anti-evidentialist contention that we should treat certain religious beliefs as properly basic. In order to support this anti-skeptical maneuver, Plantinga (along with other “reformed” epistemologists such as William Alston) has looked to the kind of anti-evidentialist model that is standardly offered as regards the epistemology of perceptual belief and has claimed that there are sufficient analogies between perceptual experience and religious experience to moti- vate the use of such a model in religious epistemology. It is argued here, however, that while Plantinga et al. are right to draw our attention to these analogies, in doing so they have failed to pay due attention to important disanalogies that exist between religious and perceptual experience. Moreover, I contend that these disanalogies have epistemo- logical ramifications that require subtle modifications to the reformed epistemology thesis. In particular, following a suggestion made by Keith DeRose, I argue that re- formed epistemology would be better modelled along explicitly virtue-theoretic lines.

The recent literature on the theory of knowledge has taken a distinctive turn by focusing on the role of the cognitive and intellectual virtues in the acquisition of knowledge. The main contours and motivations for such virtue-theoretic accounts of knowledge are here sketched and it is argued that virtue epistemology in its most plausible form can be regarded as a refined form of reliabilism, and thus a variety of epistemic externalism. Moreover, it is claimed that there is strong empirical support in favour of the virtue epistemic position so understood, and an empirical study regarding the cognitive processes employed by medical experts in their diagnosis and treatment of epilepsy is cited in this regard. In general, it is argued that one can best account for 'expert' knowledge in terms of a virtue-theoretic epistemology that retains key reliabilist features. It is thus shown that understanding knowledge along virtue-theoretic lines has important implications for our understanding of how knowledge is acquired, and thus for the philosophy of education.

A conspicuous oversight in recent debates about the vexed problem of the value of knowledge has been the value of knowledge-how. This would not be surprising if knowledge-how were, as Gilbert Ryle [1945, 1949] famously thought, fundamentally different from knowledge-that. However, reductive intellectualists [e.g. Stanley and Williamson 2001; Brogaard 2008, 2009, 2011; Stanley 2011a, 2011b] maintain that knowledge-how just is a kind of knowledge-that. Accordingly, reductive intellectualists must predict that the value problems facing propositional knowledge will equally apply to knowledge-how. We show, however, that this is not the case. Accordingly, we highlight a value-driven argument for thinking that knowledge-how and knowledge-that come apart

Achievements are clearly something that we care about. We want a life rich in achievements, and we value the achievements of others. To be appointed to the job of one's dreams as a result of one's hard work and raw talent, such that it constitutes an achievement on one's part, is far more satisfying and worthy than getting it through other means where no achievement is involved . Similarly, the Olympic goal medal winner who gets her award by being the best in a strong field exhibits an achievement and is lauded for it, but her counterpart who attains the same result through, say, mere good luck , and who thus does not exhibit an achievement, is not gifted nearly as much praise. But what is an achievement, and what is it about achievements that makes us care about them so much?

Philosophers of information, according to Luciano Floridi (The philosophy of information. Oxford University Press, Oxford, 2010, p 32), study how information should be “adequately created, processed, managed, and used.” A small number of epistemologists have employed the concept of information as a cornerstone of their theoretical framework. How this concept can be used to make sense of seemingly intractable epistemological problems, however, has not been widely explored. This paper examines Fred Dretske’s information-based epistemology, in particular his response to radical epistemological skepticism. We discuss the relationship between information, evidence and knowledge in relation to the problem of skepticism and the options available to an information-based epistemology for dealing with it.

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.

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.
