1. I am going to work with an idea from Sellars, that knowledge—at least as enjoyed by rational animals—is a certain sort of standing in the space of reasons. My concern is a familiar philosophical dialectic, which I shall approach in terms of what happens to the Sellarsian idea when the image of standings in the space of reasons undergoes a certain deformation. That it is a deformation is something we can learn from how unsatisfactory the familiar dialectic is.

Duncan Pritchard recently proposed a Wittgensteinian solution to closure-based skepticism. According to Wittgenstein, all epistemic systems assume certain truths. The notions that we are not disembodied brains, that the Earth has existed for a long time and that one’s name is such-and-such all function as “hinge commitments.” Pritchard views a hinge commitment as a positive propositional attitude that is not a belief. Because closure principles concern only knowledge-apt beliefs, they do not apply to hinge commitments. Thus, from the fact that (...) a subject knows that he is sitting in a room, and the fact that the subject’s sitting in a room entails his bodily existence, it does not follow that the subject also knows that he is not an envatted brain. This paper rejects Pritchard’s non-belief reading of hinge commitments. I start by showing that the non-belief reading fails to solve the skeptical paradox because the reasons that Pritchard uses to support the non-belief reading do not exempt hinge propositions from closure principles. I then proceed to argue that the non-belief reading is false as it claims that hinge commitments, unlike ordinary beliefs, are rationally unresponsive—with the help of a scenario in which a subject’s experience is internally chaotic, we can safely conclude that the hinge commitment that one is not systematically mistaken about the world is equally responsive to one’s evidential situations.

This paper explores ‘reasonable doubt’ as an enlightening notion to think of reasoning and decision-making generally, beyond the judicial domain. The paper starts from a decision-theoretic understanding of the notion, whereby it can be defined in terms of degrees of belief and a probabilistic confirmation threshold for action. It then highlights some of the limits of this notion, and proposes a richer analysis of epistemic states and reasoning through the lens of ‘reasonable doubt’, which in turn is likely to supplement (...) the DT framework. The strategy consists in fighting on two fronts: with DT, the paper claims that there is no absolute notion of ‘reasonable doubt’ but, pace DT, it shows that reasonable doubt cannot be accounted for only in terms of degrees of belief and probabilistic threshold. We argue that the lens of reasonable doubt sheds light on aspects of belief dynamics, as well as of the nature of epistemic attitudes, which are often obscured by belief-centred approaches. In particular, when it comes to acknowledging the necessary ignorance and irreducible uncertainty that we face in our everyday-life decisions, studying the various facets of doubt rather than focusing on what can be believed, enables one to do justice to the richness and diversity of the mental states in play.

Recent views in hinge epistemology rely on doxastic normativism to argue that our attitudes towards hinge propositions are not beliefs. This paper has two aims; the first is positive: it discusses the general normative credentials of this move. The second is negative: it delivers two negative results for No-Belief hinge epistemology such construed. The first concerns the motivation for the view: if we’re right, doxastic normativism offers little in the way of theoretical support for the claim that our attitudes towards (...) hinge propositions are anything but garden-variety beliefs. The second concerns theoretical fruitfulness: we show that embracing a No-Belief view will either get us in serious theoretical trouble, or loose all anti-sceptical appeal. (shrink)

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.

The goal of this paper is to mark the transition from an anti-luck epistemology to an anti-risk epistemology, and to explain in the process how the latter has advantages over the former. We begin with an account of anti-luck epistemology and the modal account of luck that underpins it. Then we consider the close inter-relationships between luck and risk, and in the process set out the modal account of risk that is a natural extension of the modal account of luck. (...) Finally, we apply the modal account of risk to epistemology in order to develop an anti-risk epistemology, and then explore the merits of this proposal. In particular, it is shown that this account can avoid a theoretical lacuna in anti-luck epistemology, and there is a stronger theoretical motivation for anti-risk epistemology compared with anti-luck epistemology, especially when it comes to explaining why environmental epistemic luck is incompatible with knowledge.

Epistemic Angst offers a completely new solution to the ancient philosophical problem of radical skepticism—the challenge of explaining how it is possible to have knowledge of a world external to us. Duncan Pritchard argues that the key to resolving this puzzle is to realize that it is composed of two logically distinct problems, each requiring its own solution. He then puts forward solutions to both problems. To that end, he offers a new reading of Wittgenstein's account of the structure of (...) rational evaluation and demonstrates how this provides an elegant solution to one aspect of the skeptical problem. Pritchard also revisits the epistemological disjunctivist proposal that he developed in previous work and shows how it can effectively handle the other aspect of the problem. Finally, he argues that these two antiskeptical positions, while superficially in tension with each other, are not only compatible but also mutually supporting. The result is a comprehensive and distinctive resolution to the problem of radical skepticism, one that challenges many assumptions in contemporary epistemology. (shrink)

Artists often emphasize the importance of risk to their work. But this raises a puzzle, as on a standard probabilistic account of risk we are obliged to treat some of these cases as not involving genuine risk at all. It is argued that the way to resolve this puzzle is to recognize a crucial shortcoming in the probabilistic account of risk. With this shortcoming rectified, and hence with a revised modal account of risk in place, we are able to treat (...) the relevant cases of putative aesthetic risk as entirely genuine. (shrink)

Support is canvassed for a new approach to epistemology called anti-risk epistemology. It is argued that this proposal is rooted in the motivations for an existing account, known as anti-luck epistemology, but is superior on a number of fronts. In particular, anti-risk epistemology is better placed than anti-luck epistemology to supply the motivation for certain theoretical moves with regard to safety-based approaches to knowledge. Moreover, anti-risk epistemology is more easily extendable to epistemological questions beyond that in play in the theory (...) of knowledge specifically. A key advantage of the view, however, is that anti-risk epistemology fares much better than anti-luck epistemology when it comes to accounting for the phenomenon of negative epistemic dependence. In particular, anti-risk epistemology is ideally placed to explain why such epistemic dependence is incompatible with knowledge, even when the negative epistemic dependence in play is of a purely modal variety.

Rieber 1998 proposes an account of "S knows that p" that generates a contextualist solution to Closure. In this paper, I’ll argue that Rieber’s account of "S knows that p" is subject to fatal objections, but we can modify it to achieve an adequate account of "S knows that p" that generates a unified contextualist solution to all four puzzles. This is a feat that should matter to those philosophers who have proposed contextualist solutions to Closure: all of them have (...) motivated their contextualism by appeal to the fact that they can explain the plausibility of each of the statements in Closure taken individually, and they can do this without having to deny that each of those statements is true, at least in the context in which it is plausible. But notice that this consideration would equally well motivate a contextualist approach to the other puzzles. Nonetheless, no contextualist has yet suggested how a contextualist solution to the other puzzles might go. (shrink)

A skeptic claims that I do not have knowledge of the external world. It has been thought that the skeptic reaches this conclusion because she employs unusually stringent standards for knowledge. But the skeptic does not employ unusually high standards for knowledge. Rather, she employs unusually restrictive standards of evidence. Thus, her claim that we lack knowledge of the external world is supported by considerations that would equally support the claim that we lack evidence for our beliefs about the external (...) world. These considerations do not threaten the truth of our ordinary attributions of evidence, however, for such attributions are context-sensitive in their semantics. It is argued that this solution to the problem of the external world enjoys all of the benefits, and suffers none of the problems, of other solutions to the problem of the external world. (shrink)

Wittgenstein’s On Certainty is sometimes read as providing a response to the skeptical puzzle from closure, according to which our commitment to the trustworthiness of our evidence is not itself evidentially grounded. In this paper, I argue both that this standard reading of Wittgenstein is incorrect, and that a more accurate reading of Wittgenstein provides us with a more plausible solution to the Closure Puzzle.

Duncan Pritchard’s Epistemic Angst promises a novel solution to the closure-based sceptical problem that, unlike more traditional solutions, does not entail revising our fundamental epistemological commitments. In order to do this, it appeals to a Wittgensteinian account of rational evaluation, the overarching theme of which is that it neither makes sense to doubt nor to believe in our anti-sceptical hinge commitments. The purpose of this paper is to show that the argument for the claim that there can be no rational (...) basis to believe our anti-sceptical hinge commitments relies upon an implicit assumption about rational support that I label The Pritchensteinian Rational Grounds Principle. I argue that, insofar as this principle is intended to apply to closure-style inferences, it leads to irrational doxastic attitudes. I consider a seemingly plausible modification of the principle that would avoid this result but show that this modified principle faces serious problems of its own. -/- . (shrink)

I defend two theses here. First, I argue that at least many of the commitments that Wittgenstein identifies as “hinge commitments” are plausibly what cognitive psychology and artificial intelligence call “procedural knowledge.” Procedural knowledge can be implemented in cognitive systems in a variety of ways, and these modes of implementation, I argue, predict several properties of Wittgensteinian hinge commitments, including their functional profile, as well as other of their characteristic features. Second, I argue that thinking of hinge commitments as a (...) kind of procedural knowledge allows a unified virtue-theoretic treatment of the generation of knowledge, the transmission of knowledge, and Wittgensteinian “hinge knowledge.” This last thesis is noteworthy, in that Wittgenstein and his defenders have so far failed to offer any unified epistemology of hinge commitments and the knowledge that such commitments are supposed to make possible.

The law views with suspicion statistical evidence, even evidence that is probabilistically on a par with direct, individual evidence that the law is in no way suspicious of. But it has proved remarkably hard to either justify this suspicion, or to debunk it. In this paper, we connect the discussion of statistical evidence to broader epistemological discussions of similar phenomena. We highlight Sensitivity – the requirement that a belief be counterfactually sensitive to the truth in a specific way – as (...) a way of epistemically explaining the legal suspicion towards statistical evidence. Still, we do not think of this as a satisfactory vindication of the reluctance to rely on statistical evidence. Knowledge – and Sensitivity, and indeed epistemology in general – are of little, if any, legal value. Instead, we tell an incentive-based story vindicating the suspicion towards statistical evidence. We conclude by showing that the epistemological story and the incentive-based story are closely and interestingly related, and by offering initial thoughts about the role of statistical evidence in morality.

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. (shrink)

The book was planned and written as a single, sustained argument. But earlier versions of a few parts of it have appeared separately. The object of this book is both to establish the existence of the paradoxes, and also to describe a non-Pascalian concept of probability in terms of which one can analyse the structure of forensic proof without giving rise to such typical signs of theoretical misfit. Neither the complementational principle for negation nor the multiplicative principle for conjunction applies (...) to the central core of any forensic proof in the Anglo-American legal system. There are four parts included in this book. Accordingly, these parts have been written in such a way that they may be read in different orders by different kinds of reader. (shrink)

Tyler Burge presents an original study of the most primitive ways in which individuals represent the physical world. By reflecting on the science of perception and related psychological and biological sciences, he gives an account of constitutive conditions for perceiving the physical world, and thus aims to locate origins of representational mind.

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

It is claimed that McDowell’s treatment of scepticism offers a potential way of resurrecting the much derided ‘Moorean’ response to scepticism in a fashion that avoids the problems facing classical internalist and externalist construals of neo-Mooreanism. I here evaluate the prospects for a McDowellian neo-Mooreanism and, in doing so, offer further support for the view.

Does scepticism threaten our common sense picture of the world? Does it really undermine our deep-rooted certainties? Answers to these questions are offered through a comparative study of the epistemological work of two key figures in the history of analytic philosophy, G. E. Moore and Ludwig Wittgenstein.

These lectures by one of the most influential and original philosophers of the twentieth century constitute a sustained argument for the philosophical basis of romanticism, particularly in its American rendering. Through his examination of such authors as Emerson, Thoreau, Poe, Wordsworth, and Coleridge, Stanley Cavell shows that romanticism and American transcendentalism represent a serious philosophical response to the challenge of skepticism that underlies the writings of Wittgenstein and Austin on ordinary language.

Language matters to epistemology for two separate reasons (although they are no doubt connected) -/- My interest in testimony derives from Gareth Evans, as does my conviction that it cannot be accommodated by the sort of account of knowledge which I attack in this paper. I believe I also owe to him my interest in the sorts of case I discuss in §4 below, where knowledge is retained under the risk that what would have been knowledge if the relevant fact (...) had still obtained is not knowledge because the fact no longer obtains. I have benefited from comments by Robert Brandom and Jonathan Dancy. (shrink)
