Skepticism: From Antiquity to the Present is an authoritative and up-to-date survey of the entire history of skepticism. Divided chronologically into ancient, medieval, renaissance, modern, and contemporary periods, and featuring 50 specially-commissioned chapters from leading philosophers, this comprehensive volume is the first of its kind.

Almost every contemporary theory of knowledge is a version of fallibilism, yet an adequate statement of fallibilism has not yet been provided. Standard definitions cannot account for fallibilistic knowledge of necessary truths. I consider and reject several attempts to resolve this difficulty before arguing that a belief is an instance of fallibilistic knowledge when it could have failed to be knowledge. This is a fully general account of fallibilism that applies to knowledge of necessary truths. Moreover, it reveals, not only (...) the connection between fallibility and error, but the connection between fallibility and accidental truth as well. (shrink)

Although recent epistemology has been marked by several prominent disagreements – e.g., between foundationalists and coherentists, internalists and externalists – there has been widespread agreement that some form of fallibilism must be correct. According to a rough formulation of this view, it is possible for a subject to have knowledge even in cases where the justification or grounding for the knowledge is compatible with the subject’s being mistaken. In this paper, I examine the motivation for fallibilism before providing a fully (...) general account of the view. I conclude by looking at the two major difficulties for fallibilism: the Gettier problem and the lottery paradox. (shrink)

There have been several recent attempts to account for the special authority of self-knowledge by grounding it in a constitutive relation between an agent's intentional states and her judgments about those intentional states. This constitutive relation is said to hold in virtue of the rationality of the subject. I argue, however, that there are two ways in which we have self-knowledge without there being such a constitutive relation between first-order intentional states and the second-order judgments about them. Recognition of this (...) fact thus represents a significant challenge to the rational agency view. (shrink)

Epistemic circularity occurs when a subject forms the belief that a faculty F is reliable through the use of F. Although this is often thought to be vicious, externalist theories generally don't rule it out. For some philosophers, this is a reason to reject externalism. However, Michael Bergmann defends externalism by drawing on the tradition of common sense in two ways. First, he concedes that epistemically circular beliefs cannot answer a subject's doubts about her cognitive faculties. But, he argues, subjects (...) don't have such doubts, so epistemically circular beliefs are rarely called upon to play this role. Second, following Thomas Reid, Bergmann argues that we have noninferential, though epistemically circular, knowledge that our faculties are reliable. I argue, however, that Bergmann's view is undermined by doubts a subject should have and that there is no plausible explanation for how we can have noninferential knowledge that our faculties are reliable. (shrink)

The traditional argument for skepticism relies on a comparison between a normal subject and a subject in a skeptical scenario: because there is no relevant difference between them, neither has knowledge. Externalists respond by arguing that there is in fact a relevant difference—the normal subject is properly situated in her environment. I argue, however, that there is another sort of comparison available—one between a normal subject and a subject with a belief that is accidentally true—that makes possible a new argument (...) for skepticism. Unlike the traditional form of skeptical argument, this new argument applies equally well to both internalist and externalist theories of knowledge. (shrink)

Knowledge is standardly taken to be belief that is both true and justified (and perhaps meets other conditions as well). Timothy Williamson rejects the standard epistemology for its inability to solve the Gettier problem. The moral of this failure, he argues, is that knowledge does not factor into a combination that includes a mental state (belief) and an external condition (truth), but is itself a type of mental state. Knowledge is, according to his preferred account, the most general factive mental (...) state. I argue, however, that Gettier cases pose a serious problem for Williamson’s epistemology: in these cases, thesubject may have a factive mental state that fails to be cognitive. Hence, knowledge cannot be the most general factive mental state. (shrink)

Ernest Sosa's virtue perspectivism can be thought of as an attempt to capture as much as possible of the Cartesian project in epistemology while remaining within the framework of externalist fallibilism. I argue (a) that Descartes's project was motivated by a desire for intellectual stability and (b) that his project does not suffer from epistemic circularity. By contrast, Sosa's epistemology does entail epistemic circularity and, for this reason, proves unable to secure the sort of intellectual stability Descartes wanted. I then (...) argue that this leaves Sosa's epistemology vulnerable to an important kind of skepticism. (shrink)

One of the main strands of the Cartesian tradition is the view that the mental realm is cognitively accessible to us in a special way: whenever one is in a mental state of a certain sort, one can know it just by considering the matter. In that sense, the mental realm is thought to be a cognitive home for us, and the mental states it comprises are luminous. Recently, however, Timothy Williamson has argued that we are cognitively homeless: no mental (...) state is in fact luminous. But his argument depends on an excessively strong account of luminosity. I formulate a weaker conception of luminosity that is unaffected by Williamson’s argument and yet is substantial enough to satisfy those who wish to retain this part of the Cartesian tradition.

There have been several recent attempts to account for the special authority of self‐knowledge by grounding it in a constitutive relation between an agent’s intentional states and her judgments about those intentional states. This constitutive relation is said to hold in virtue of the rationality of the subject. I argue, however, that there are two ways in which we have self‐knowledge without there being such a constitutive relation between first‐order intentional states and the second‐order judgments about them. Recognition of this (...) fact thus represents a significant challenge to the rational agency view. (shrink)

This chapter traces the significance of a common feature of action and knowledge. A successful analysis of action must capture the sense in which there is someone who is acting. Similarly, it is argued, a successful analysis of knowledge must capture the sense in which there is someone who knows. Explicitly recognizing this fact helps to explain the importance of epistemic agency in understanding what knowledge is. This chapter explores the connections between knowledge, agency, and personhood and argues that some (...) of the most widely shared intuitions in epistemology can be grounded in the sense that knowledge belongs to persons. The chapter comments on the way in which a claim of this sort has been taken up by virtue epistemology, as well as the difficulties we face in providing a full understanding of how knowledge can belong to persons. The chapter closes with a consideration of the value of knowledge. (shrink)

This book collects cutting edge essays on epistemic agency and related topics by distinguished senior contributors to epistemology, as well as rising figures in the field. The assembly of scholars is impressive, as is reflected by the quality and range of their contributions.

Any theory of knowledge that is fallibilist—i.e., that allows for one to have knowledge that could have been false or accidentally true—faces the lottery paradox. The paradox arises from the combination of two plausible claims: first, no one can know that one’s lottery ticket will lose prior to learning that it in fact has lost, and, second, the justification one has for the belief that one’s ticket will lose is just as good as the justification one has for paradigmatic instances (...) of knowledge. In thispaper, I offer a solution to the lottery paradox that is grounded in a thorough-going acceptance of fallibilism. (shrink)

Fallibilism is the philosophical view that reconciles our ability to have knowledge with our constant vulnerability to error: we know even though our basis for knowledge might have failed to be adequate. In the central chapter, I trace a parallel between fallibilism and compatibilism. Recent work in the philosophy of free agency has drawn attention to a connection between freedom and personhood . I suggest that a similar connection is crucial in epistemology: only persons can know, and knowledge must be (...) connected with what constitutes a subject as a cognitive person. Fallibilism and compatibilism offer what I call world-involving theories of personhood: what constitutes one as a person essentially involves how one is connected to the world. These world-involving theories face difficulties in showing how a person can be properly related to the thing known or to an action . I argue that fallibilism and compatibilism are incapable of resolving these problems and, hence, that world-involving theories of personhood are fundamentally flawed. Other chapters develop closely related themes: the proper analysis of fallibilism, the importance of the intellectual virtues and their role in epistemic agency, the kinds of accidentality that may undermine knowledge, and disjunctivism as a response to skepticism. Disjunctivism is a view that attempts to combine fallibilism with the ability to have a direct awareness of the truth . I examine this view as it is developed both in current epistemology and by the ancient Stoics. (shrink)

Many people find their encounter with sceptical arguments to be puzzling. A few even find them disturbing enough to warrant writing refutations. Nathan’s approach is different. He is willing to concede that some sceptical arguments are sound; he denies, however, that this matters. The conjecture that Nathan tests in this book is that “no sound sceptical argument has a conclusion whose truth value is anything but a matter of indifference”. His focus, then, is not so much on the sceptical arguments (...) themselves as on our reactions to them. (shrink)

When one depends on a belief source in sustaining a belief that that very belief source is trustworthy, then that belief is an epistemically circular belief. A number of philosophers have objected to externalism in epistemology on the grounds that it commits one to thinking EC-beliefs can be justified, something they view as an unhappy consequence for externalism. In my 2004, I defend externalism against this sort of charge by explaining why this consequence needn’t be an unhappy one. In the (...) course of doing so, I appeal to what Thomas Reid calls ‘common sense’—a faculty or belief source by which we know noninferentially such things as that our faculties are trustworthy. In his 2006, Baron Reed raises what he takes to be serious objections to what I say about both epistemic circularity and common sense. In what follows, I’ll respond to his objections, explaining why I side with Reid against Reed. (shrink)

This article is a reply to Baron Reed and Heather Battaly, two critics in a book symposium on my Reflective Knowledge. The reply to Reed concerns the main content and structure of Descartes's epistemology. The reply to Battaly concerns how best to deal with epistemic circularity.

Baron Reed has developed a new argument for skepticism: (1) contemporary epistemologists are all committed to two theses, fallibilism and attributabilism; unfortunately, (2) these two theses about knowledge are incompatible; therefore, (3) knowledge as conceived by contemporary epistemologists is impossible. In this brief paper I suggest that Reed's argument appears to rest on an understanding of attributabilism that is so strong (call it maximal attributabilism) that it's doubtful that many contemporary epistemologists actually embrace it. Nor does (...) class='Hi'>Reed offer any direct argument for the truth of maximal attributabilism. Therefore, we need not be persuaded by Reed's new argument for skepticism. (shrink)

"In the 25 essays that comprise this grimly fascinating volume, Reed shines a light into some very dark corners. From its opening tale of South African baboons with a taste for human babies to a thoroughly icky account of a middle-aged woman's seduction of young boys, these are literary snapshots of the world at its worst."--Amazon.com.

The emphasis on duly in Kant's ethics is widely held to constitute a defect. Marcia W. Baron develops and assesses the criticism, which she sees as comprising two objections: that duty plays too large a role, leaving no room for the supererogatory, and that Kant places too much value on acting from duty. Clearly written and cogently argued, Kantian Ethics Almost without Apology takes on the most philosophically intriguing objections to Kant's ethics and subjects them to a rigorous yet (...) sympathetic assessment.

According to recent commentators like Paul Guyer, Kant agrees with Hume's Dialogues Concerning Natural Religion that physico-theology can never provide knowledge of God and that the concept of God, nevertheless, provides a useful heuristic principle for scientific enquiry. This paper argues that Kant, far from agreeing with Hume, criticizes Hume's Dialogues for failing to prove that physico-theology can never yield knowledge of God and that Kant correctly views Hume's Dialogues as a threat to, rather than an anticipation of, his own (...) view that the concept of God provides a useful heuristic principle for science. The paper concludes that Kant's critique of physico-theology reflects Kant's deep dissatisfaction with Hume's manner of argumentation and suggests that Kant's attempt to provide a more successful critique of physico-theology merits continued philosophical attention.

We develop a new version of the causal theory of spacetime. Whereas traditional versions of the theory seek to identify spatiotemporal relations with causal relations, the version we develop takes causal relations to be the grounds for spatiotemporal relations. Causation is thus distinct from, and more basic than, spacetime. We argue that this non-identity theory, suitably developed, avoids the challenges facing the traditional identity theory.

La société contemporaine est constamment confrontée aux problèmes religieux. Cependant, la tradition républicaine française abandonne la religion à la sphère privée, comme si elle n'avait pas, par essence, une existence dans la Cité. Il ne s'agit pas pour autant de réduire la religion à sa dimension politique, voire au militantisme fanatique. La critique des réductions illégitimes de la religion est donc la première tâche. Il est aussi impossible de privatiser la religion que de la politiser. La réduire au lien social (...) n'est pas plus satisfaisant, même si c'est une tentation des sociologues. La religion ne se réduit pas davantage à la religiosité du sublime ou de l'idéal démocratique. Contre la notion scabreuse de " religions sans Dieu ", il vaut mieux admettre qu'il existe du religieux diffus sans religion, et garder le terme pour désigner une relation à la transcendance divine (une ou multiple) à la fois et indissolublement singulière et collective. Ainsi, il n'y a pas de religion sans prière individuelle, contrairement à ce que Kant souhaitait. Mais cette prière n'a aucun sens si elle ne s'adosse pas à un message intersubjectif, celui d'une communauté inspirée qui s'inscrit dans la Cité par sa dimension sociale et son histoire. La dimension personnelle de la religion (foi et méditation) s'appuie donc sur le symbolique, le témoignage et la communauté. Pour le philosophe d'aujourd'hui, les religions se présentent comme l'attestation multiple de la présence d'une transcendance divine et d'une vie spirituelle dans la société et dans l'histoire. Mettre la religion entre parenthèses, c'est s'exposer à ne rien comprendre de l'histoire du monde. (shrink)

I introduce an argument for Platonism based on intra-mathematical explanation: the explanation of one mathematical fact by another. The argument is important for two reasons. First, if the argument succeeds then it provides a basis for Platonism that does not proceed via standard indispensability considerations. Second, if the argument fails it can only do so for one of three reasons: either because there are no intra-mathematical explanations, or because not all explanations are backed by dependence relations, or because some form (...) of noneism-the view according to which non-existent entities possess properties and stand in relations-is true. The argument thus forces a choice between nominalism without noneism, intra-mathematical explanation and a backing conception of explanation. You can have any two, but not all three. (shrink)

In this paper I investigate Socrates as a friend in Plato's 'Phaedo'. I begin by setting out his friends' request for reassurance of how they will fare after Socrates dies. I argue that by structuring the discussion as he does, Socrates provides one final opportunity for his friends to prepare themselves for life without him, thus offering them the best kind of reassurance they could ask for.
