My interest is in an apparent tension between two epistemological theses. The first is veritism, which is roughly the claim that truth is the fundamental epistemic good. The second is the idea that understanding is the proper goal of inquiry. The two theses seem to be in tension because the former seems to imply that the proper goal of inquiry should be truth rather than understanding. And yet there is a strong prima facie case to be made for thinking that properly conducted inquiry aims at an elevated epistemic standing like understanding rather than merely true belief. I suggest that this putative tension is one of the reasons why veritism is these days not widely endorsed. As I show, however, there is in fact no tension between these two claims, at least once they are each properly understood. Indeed, I will be suggesting that there is a plausible conception of veritism which would explain why intellectual exemplars seek out understanding in inquiry.

I want to suggest a way of approaching On Certainty that treats what Wittgenstein is doing in the notebooks that make up this work as manifesting a kind philosophical practice that is broadly Pyrrhonian, at least on one reading of what this involves. Such a reading fits with the general philosophical quietism found in Wittgenstein’s work, particularly in his later writings, and is also supported by independent textual evidence that he was profoundly influenced by Pyrrhonian scepticism. Crucially, however, it also helps to clarify the sense in which the Pyrrhonian sceptical techniques, and hence the kind of philosophical quietism that goes along with them, can have an essentially disquieting effect on the subject.

What is knowledge? Where does it come from? What kinds of knowledge are there? Can we know anything at all? What is the practical relevance of learning about epistemology? This lucid and engaging introduction grapples with these central questions in the theory of knowledge, offering a clear, non-partisan view of the main themes of epistemology. Both traditional issues and contemporary ideas are discussed in twenty easily digestible chapters, each of which conclude with a useful summary of the main ideas discussed, study questions, annotated further reading and a guide to internet resources. Each chapter also features text boxes providing bite-sized summaries of key concepts and major philosophers, and clear and interesting examples are used throughout. The book concludes with an annotated guide to general introductions to epistemology, a glossary of key terms, and a summary of the main examples used in epistemology. This is an ideal first textbook in the theory of knowledge for undergraduates coming to philosophy for the first time. The fifth edition has been revised and updated throughout and features two new chapters on social epistemology. In addition, the text as a whole has been refreshed to keep it up to date with current developments.

What is knowledge? Where does it come from? What kinds of knowledge are there? Can we know anything at all? This lucid and engaging introduction grapples with these central questions in the theory of knowledge, offering a clear, non-partisan view of the main themes of epistemology. Both traditional issues and contemporary ideas are discussed in sixteen easily digestible chapters, each of which conclude with a useful summary of the main ideas discussed, study questions, annotated further reading and a guide to internet resources. Each chapter also features text boxes providing bite-sized summaries of key concepts and major philosophers, and clear and interesting examples are used throughout. The book concludes with an annotated guide to general introductions to epistemology, a glossary of key terms, and a summary of the main examples used in epistemology, This an ideal first textbook in the theory of knowledge for undergraduates coming to philosophy for the first time. The third edition has been revised and updated throughout and features two new chapters, on religious knowledge and scientific knowledge, as part of a whole new section on what kinds of knowledge there are. In addition, the text as a whole has been refreshed to keep it up to date with current developments.

It is argued that in order to properly engage with the debate regarding the ethics of belief one first needs to determine the nature of the propositional attitude in question. This point is illustrated by discussing a related topic from social philosophy, broadly conceived, concerning the nature of, and inter-relationship between, delusions and the Wittgensteinian notion of a hinge commitment. Are we to understand either or both of these notions as beliefs? Are delusions a kind of hinge commitment? In answering these questions we will appeal to a distinction between folk belief and knowledge-apt belief. It is argued that while both delusions and hinge commitments count as beliefs in the former sense, neither is a belief in the latter sense. Moreover, once we understand what is involved in the notion of a hinge commitment, it will also become clear why delusions are not hinge commitments. It is claimed that by gaining an understanding of delusions and hinge commitments, and thereby of two fundamental ways of thinking about belief, we will be in a better position to determine what is at issue in the ethics of belief debate.

I examine one key way in which the problem of radical scepticism is motivated via an appeal to an infallibility thesis—as expressed, for example, in the work of Peter Unger—and highlight how this construal of the sceptical problem presupposes a certain view about epistemic luck. Furthermore, I explore the manner in which an infallibilism-based scepticism gives rise to the kind of template-sceptical argument that is the focus of much of the contemporary discussion of scepticism and which turns on the ‘closure’ principle that knowledge is ‘closed’ under known entailments.

I maintain that the neo-Moorean response to scepticism is unable, by itself at any rate, to completely resolve the sceptical problem. The reason for this is that the contemporary discussion of scepticism has misunderstood what the source of this problem is, and thus even the most plausible of the main anti-sceptical theories in the literature misses its intended target. To illustrate this, I contrast the closure-based template sceptical argument with its analogue argument expressed in terms of the ‘underdetermination’ principle that can be found in ancient Pyrrhonian sceptical writings, and which merely demands that one’s evidence should favour one’s beliefs over incompatible alternatives. I show how the latter argument brings to the fore just what is wrong with the contemporary debate regarding scepticism, which is its failure to respond to the specifically internalist and evidentialist character of the sceptical doubt.

I examine two species of epistemic luck that I claim are not benign and explain how they feature in the main epistemological debates. The first species of epistemic luck—what I call ‘veritic’ luck—can be handled with a modest ‘relevant alternatives’ account of knowledge that is specifically defined so that it counters this type of epistemic luck. As I explain, such a theory is essentially a version of the safety-based neo-Moorean thesis that we looked at in Ch. 3. I develop this view by considering some of the main examples that are discussed in epistemology—such as Gettier examples, the ‘lottery’ puzzle, and ‘barn façade’ examples—and show how the neo-Moorean account can in each case generate the right result. Along the way the formulation of this anti-veritic-luck thesis is refined in response to potential challenges that might be presented to the view. Significantly, however, the chapter closes by arguing that there is a second species of epistemic luck—what I call ‘reflective luck’-that is epistemically problematic and that is not dealt with by the neo-Moorean account.

I discuss the sceptical challenge in the light of the distinction between veritic and reflective epistemic luck and argue that the inadequacy of the main anti-sceptical proposals in the contemporary literature is a result of how they only eliminate veritic luck, and thus do not engage with the problem of reflective luck at all. Crucially, however, I claim that it is the specific challenge posed by reflective luck that is central to the sceptical problem, and yet there is a fundamental sense in which this type of epistemic luck is ineliminable. I argue that it is this sceptical problem that informs the Pyrrhonian sceptical challenge of antiquity. Moreover, I further maintain that the so-called ‘metaepistemological’ sceptical challenge that features prominently in contemporary epistemological debate—as advanced, for example, by Barry Stroud and Richard Fumerton—is best understood in terms of the specific sceptical problem regarding the ineliminability of reflective luck.

I contend that in so far as the contemporary debate about scepticism has formulated the sceptical problem correctly, and in so far as one is entitled to adopt epistemological externalism as part of one’s anti-sceptical strategy, one should reject both the arguments for non-closure and for attributer contextualism, and advance, instead, a version of neo-Mooreanism that turns on the so-called ‘safety’ condition on knowledge. I explore the implications of this approach for the sceptical problem, including the manner in which it needs to be distinguished from the type of response to scepticism that is associated with G. E. Moore’s famous proof of an external world. A key component of this argument in this respect is an account of the conversational rules that govern our ascriptions of knowledge that can do justice to the intuitions that motivate attributer contextualism, while also explaining why the kind of anti-sceptical assertions made by Moore are so problematic. As regards the latter, I enlist elements of Wittgenstein’s critique of Moore’s response to the sceptic from On Certainty. I conclude that what these considerations highlight is a deep and important truth about the structure of reasons.

I outline how an analysis of epistemic luck has ramifications for the supposedly parallel debate regarding moral luck. Focusing on the two classic papers on moral luck by Thomas Nagel and Bernard Williams, I examine the arguments and examples put forward in this regard and highlight how a primarily epistemological analysis can be put into service to cast light on the corresponding moral debate. In particular, I show that these authors fail to distinguish a specifically moral problem, and that what difficulties they do highlight are parasitic on the problem of reflective epistemic luck. I conclude that there is a strong prima facie case for thinking that there is no such thing as moral luck, and that the only reason why many think that there is because they are confusing the non-existent problem of moral luck with the entirely genuine problem of reflective epistemic luck.

I critically examine two of the main responses to the closure-based sceptical argument. In particular, I look at the case that has been made for the rejection of closure by, for example, Fred Dretske and Robert Nozick, and examine the so-called ‘sensitivity’ condition on knowledge that they advocate in this respect. I then evaluate this approach in the light of the attributer contextualist response to scepticism, as developed by such figures as Stewart Cohen, Keith DeRose and David Lewis. In both cases I argue that these anti-sceptical approaches suffer by being motivated by diverse and incompatible intuitions, principally as regards their ambivalent endorsement of epistemological externalism. An exploration of the relationship between the sceptical problem and the epistemic externalism/internalism distinction is thus presented.

I discuss the difficulty posed by the ineliminability of reflective epistemic luck and offer one way of responding to this difficulty. I begin by considering Wittgenstein’s remarks on knowledge from On Certainty and consider, in particular, the specific claims he makes about the so-called ’hinge’ propositions that contextually determine the nature of epistemic evaluation. I claim that what underlies Wittgenstein’s remarks in this respect is a certain view about the ultimately groundless nature of our reason-giving practices. This way of thinking about the structure of reasons is, I argue, correlative to the thesis described here regarding the ineliminability of reflective luck. Moreover, I contend that it is our implicit philosophical recognition of this problem that gives rise to a certain kind of general anxiety about our epistemic position that I refer to as epistemic angst. This contention is further illustrated by critically evaluating John McDowell’s content externalist response to scepticism that incorporates a strongly anti-sceptical account of reasons. I close on a positive note by arguing that while there is no epistemic response available to the problem posed by reflective luck, there is a plausible pragmatic resolution to this difficulty. Indeed, I claim that an anti-sceptical thesis of this sort can be discerned from Wittgenstein’s own fragmentary remarks on scepticism, and I develop such a view in the light of Hans Reichenbach’s pragmatic response to the problem of inductive scepticism, which I maintain is cast along similar lines.
