Knowledge and its Limits presents a systematic new conception of knowledge as a kind of mental stage sensitive to the knower's environment. It makes a major contribution to the debate between externalist and internalist philosophies of mind, and breaks radically with the epistemological tradition of analyzing knowledge in terms of true belief. The theory casts new light on such philosophical problems as scepticism, evidence, probability and assertion, realism and anti-realism, and the limits of what can be known. The arguments are (...) illustrated by rigorous models based on epistemic logic and probability theory. The result is a new way of doing epistemology and a notable contribution to the philosophy of mind. (shrink)

As is well known, Aristotelian natural philosophy, and many other systems of natural philosophy since, have relied heavily on teleology and teleological causation. Somehow, the purpose or end of an obj ect can be used to predict and explain what that object does: once you know that the end of an acorn is to become an oak, and a few things about what sorts of circumstances are conducive to the attainment of this end, you can predict a lot about the (...) sprouting of the acorn and the subsequent behaviour of the piece of vegetation that results. Once you know that a rock seeks to move towards the centre of the Earth, you gain some insight into why it falls when released, and why it deforms the carpet or foot that it lands on. Once you know that the rabbit seeks to preserve itself, you can predict it will run from the fox. And so on. There are at least three features of Aristotle’s teleology, and more generally of an Aristotelian frame of mind about teleology, that may induce suspicion. One is that an end can serve as a "cause": as well as the sort of causation we all recognize, efficient causation, there are other forms, one of which is teleological causation. However, this can look less odd if we think of causes as things that figure in "because" answers to "why" questions. Whether or not self-preservation, or the rabbit’s continued existence, or something similar, causes the rabbit to run, the reply "because it seeks to continue in existence" certainly makes sense as an answer, or part of an answer, to a question about why it ran from the fox. (At present we are only. (shrink)

How should one understand knowledge-wh ascriptions? That is, how should one understand claims such as ‘‘I know where the car is parked,’’ which feature an interrogative complement? The received view is that knowledge-wh reduces to knowledge that p, where p happens to be the answer to the question Q denoted by the wh-clause. I will argue that knowledge-wh includes the question—to know-wh is to know that p, as the answer to Q. I will then argue that knowledge-that includes a contextually (...) implicit question. I will conclude that knowledge is a question-relative state. Knowing is knowing the answer, and whether one knows the answer depends (in part) on the question. (shrink)

This essay offers a rearticulation and defence of the modal account of luck that the author developed in earlier work (e.g., Pritchard ). 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 (and risk) 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.

This chapter enhances and extends a powerful and promising research program, performance-based epistemology, which stands at the crossroads of many important currents that one can identify in contemporary epistemology, including the value problem, epistemic normativity, virtue epistemology, and the nature of knowledge. Performance-based epistemology offers at least three outstanding benefits: it explains the distinctive value that knowledge has, it places epistemic evaluation into a familiar and ubiquitous pattern of evaluation, and it solves the Gettier problem. But extant versions of performance-based (...) epistemology have been the object of serious criticism. This chapter shows how to meet the objections without sacrificing the aforementioned benefits.

What modal relation must a fact bear to a belief in order for this belief to constitute knowledge of that fact? Externalists have proposed various answers, including some that combine externalism with contextualism. We shall find that various forms of externalism share a modal conception of “sensitivity” open to serious objections. Fortunately, the undeniable intuitive attractiveness of this conception can be explained through an easily confused but far preferable notion of “safety.” The denouement of our reflections, finally, will be to (...) show how replacing sensitivity with safety makes it possible to defend plain Moorean common sense against the spurious advantages over it claimed by skeptical, tracking, relevant-alternative, and contextualist accounts.

Ernest Sosa presents a new approach to the problems of knowledge and scepticism. He argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment. Sosa's virtue epistemology illuminates different varieties of scepticism, the nature and status of intuitions, and epistemic normativity.

Ernest Sosa's A Virtue Epistemology, Vol. I is arguably the single-most important monograph to be published in analytic epistemology in the last ten years. Sosa, the first in the field to employ the notion of intellectual virtue – in his ground-breaking ‘The Raft and the Pyramid’– is the leading proponent of reliabilist versions of virtue epistemology. In A Virtue Epistemology, he deftly defends an externalist account of animal knowledge as apt belief, argues for a distinction between animal and reflective knowledge, (...) contends that rational intuition is an intellectual virtue ; and offers responses to dream scepticism, the problem of the criterion and the value problem. Nearly all of these arguments are new, albeit consistent with Sosa's earlier work; that is, consistent with two notable exceptions. First, c ontra Sosa's ‘Replies’ in Ernest Sosa and His Critics, A Virtue Epistemology explicitly contends that safety is not required for animal knowledge. Second, unlike Sosa's Knowledge in Perspective, which arguably construes the intellectual virtues as merely instrumentally valuable, A Virtue Epistemology explicitly contends that the intellectual virtues are instrumentally and constitutively valuable. Best read in conjunction with the above monographs and Epistemic Justification, A Virtue Epistemology is mandatory reading for epistemologists and graduate students in the field. It will rightly set the standard for debates in analytic epistemology for years to come.I will summarize and raise objections to two key conclusions that are unique to A Virtue Epistemology: the ‘kaleidoscope-perceiver’ has animal knowledge but lacks reflective knowledge; unlike the k-perceiver, the ordinary perceiver has reflective knowledge. My objections …. (shrink)

Contextualism treats ‘knows’ as an indexical that denotes different epistemic properties in different contexts. Contrastivism treats ‘knows’ as denoting a ternary relation with a slot for a contrast proposition. I will argue that contrastivism resolves the main philosophical problems of contextualism, by employing a better linguistic model. Contextualist insights are best understood by contrastivist theory.

That believing truly as a matter of luck does not generally constitute knowing has become epistemic commonplace. Accounts of knowledge incorporating this anti-luck idea frequently rely on one or another of a safety or sensitivity condition. Sensitivity-based accounts of knowledge have a well-known problem with necessary truths, to wit, that any believed necessary truth trivially counts as knowledge on such accounts. In this paper, we argue that safety-based accounts similarly trivialize knowledge of necessary truths and that two ways of responding (...) to this problem for safety, issuing from work by Williamson and Pritchard, are of dubious success. (shrink)

It is nearly universally acknowledged among epistemologists that a belief, even if true, cannot count as knowledge if it is somehow largely a matter of luck that the person so arrived at the truth. A striking feature of this literature, however, is that while many epistemologists are busy arguing about which particular technical condition most effectively rules out the offensive presence of luck in true believing, almost no one is asking why it matters so much that knowledge be immune from (...) luck in the first place. I argue that the best explanation for the consensus that luck undermines knowledge is that knowledge is, complications aside, credit-worthy true believing. To make this case, I develop both the notions of luck and credit, and sketch a theory of knowledge in those terms. Furthermore, this account also holds promise for being able to solve the “value problem” for knowledge, and it explains why both internal and external conditions are necessary to turn true belief into knowledge.

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. (shrink)

This paper explores how a certain theory of knowledge—known as anti-luck virtue epistemology—can account for, and in the process shed light on, the notion of an epistemic defeater. To this end, an overview of the motivations for anti-luck virtue epistemology is offered, along with a taxonomy of different kinds of epistemic defeater. It is then shown how anti-luck virtue epistemology can explain: why certain kinds of putative epistemic defeater are not bona fide; how certain kinds of epistemic defeater are genuine (...) in virtue of exposing the subject to significant levels of epistemic risk; and how certain kinds of epistemic defeater are genuine in virtue of highlighting how the subject’s safe cognitive success does not stand in the appropriate explanatory relationship to her manifestation of relevant cognitive ability.

In this paper, I do three things. First, I offer an overview of an anti- luck epistemology, as set out in my book, Epistemic Luck. Second, I attempt to meet some of the main criticisms that one might level against the key theses that I propose in this work. And finally, third, I sketch some of the ways in which the strategy of anti- luck epistemology can be developed in new directions.

In his recent Knowledge and its Limits, Timothy Williamson argues that no non-trivial mental state is such that being in that state suffices for one to be in a position to know that one is in it. In short, there are no “luminous” mental states. His argument depends on a “safety” requirement on knowledge, that one’s confident belief could not easily have been wrong if it is to count as knowledge. We argue that the safety requirement is ambiguous; on one (...) interpretation it is obviously true but useless to his argument, and on the other interpretation it is false. (shrink)

Typical Gettieresque scenarios involve a subject, S, using a method, M, of believing something, p, where, normally, M is a reliable indicator of the truth of p, yet, in S’s circumstances, M is not reliable: M is deleteriously rigged. A different sort of scenario involves rigging that restores the reliability of a method M that is deleteriously rigged: M is restoratively rigged. Some theorists criticize the safe indication account of knowledge defended by Luper, Sosa, and Williamson on the grounds that (...) it treats such cases as knowledge. But other theorists also criticize the safe indication account because it treats the cases as examples of ignorance when they are really examples of knowledge. I answer both groups of critics by arguing that restorative rigging can enable us to know things, and restoratively rigged cases can meet the relevant conditions of the safe indication account.

The central thesis of robust virtue epistemology (RVE) is that the difference between knowledge and mere true belief is that knowledge involves success that is attributable to a subject's abilities. An influential objection to this approach is that RVE delivers the wrong verdicts in cases of environmental luck. Critics of RVE argue that the view needs to be supplemented with modal anti-luck condition. This particular criticism rests on a number of mistakes about the nature of ability that I shall try (...) to rectify here. (shrink)

We describe the three place relation of contrastive knowledge, which holds between a person, a target proposition, and a contrasting proposition. The person knows that p rather than that q. We argue for three claims about this relation. (a) Many common sense and philosophical ascriptions of knowledge can be understood in terms of it. (b) Its application is subject to fewer complications than non-contrastive knowledge is. (c) It applies over a wide range of human and nonhuman cases.

According to robust virtue epistemology, the difference between knowledge and mere true belief is that in cases of knowledge, the subject’s cognitive success is attributable to her cognitive agency. But what does it take for a subject’s cognitive success to be attributable to her cognitive agency? A promising answer is that the subject’s cognitive abilities have to contribute to the safety of her epistemic standing with respect to her inquiry, in order for her cognitive success to be attributable to her (...) cognitive agency. Call this idea the contribution thesis. The author will argue that the contribution thesis follows naturally from virtue epistemological accounts of knowledge, and that it is precisely the contribution thesis that allows the virtue epistemologist to deal with a wide variety of objections. Nevertheless, the principal aim of this paper is to argue that virtue epistemological theories of knowledge that are committed to the contribution thesis are ultimately untenable. There are cases of knowledge where the subject’s cognitive abilities do not improve the safety of the subject’s belief. (shrink)

I take issue with two claims that Duncan Pritchard makes in his recent book, "Epistemic Luck". The first concerns his safety-based response to the lottery problem; the second his account of the relationship between safety and intellectual virtue.

Section 1 articulates a genus-species claim: that knowledge is a kind of success from ability. Equivalently: In cases of knowledge, S’s success in believing the truth is attributable to S’s ability. That idea is then applied to questions about the nature and value of knowledge. Section 2 asks what it would take to turn the genus-species claim into a proper theory of knowledge; that is, into informative, necessary and sufficient conditions. That question is raised in the context of an important (...) line of objection against even the genus-species claim; namely, that there is no way to understand the attribution relation so that it does all the work that it is supposed to do. Section 3 reviews several extant proposals for understanding the attribution relation, and argues that none of them are adequate for answering the objection. Section 4 proposes a different way of understanding the relation, and shows how the resulting view does resolve the objection. Section 5 completes the new account by proposing a way to understand intellectual abilities. Section 6 briefly addresses Barn Façade cases and lottery propositions. Section 7 briefly addresses a question about the scope of knowledge; in particular, it shows how the new view allows a neo-Moorean response to skepticism. (shrink)

Against the traditional view, Alvin Goldman argues that logic, probability theory, and linguistic analysis cannot by themselves delineate principles of rationality or justified belief. The mind's operations must be taken into account.

This paper presents a partial analysis of perceptual knowledge, an analysis that will, I hope, lay a foundation for a general theory of knowing. Like an earlier theory I proposed, the envisaged theory would seek to explicate the concept of knowledge by reference to the causal processes that produce (or sustain) belief. Unlike the earlier theory, however, it would abandon the requirement that a knower's belief that p be causally connected with the fact, or state of affairs, that p.

Theories of knowledge as credit for true belief, or as cognitive achievement, have to face the following objection: in the famous Barn façades case, it seems that the truth of Barney's belief that he is in front of a barn is to be explained by the correct functioning of his cognitive capacities, although we are reluctant to say that he knows he is in front of a barn. Duncan Pritchard concludes from this that a safety clause, irreducible to the conditions (...) a true belief must satisfy in order to be credited to the believer, constitutes a necessary condition of knowledge. Because those who define knowledge as a cognitive achievement have not convincingly answered this objection, I intend, in the first section of this paper, to refute it by showing how practical and doxastic achievements differ. Then I defend the idea that we should also distinguish two kinds of environmental epistemic luck, and, correlatively, two kinds of safety, that are not equally incompatible with knowledge. Finally, I argue that this distinction is inevitably vague and I indicate some consequences of this vagueness for our knowledge‐intuitions. (shrink)

Luck looms large in numerous different philosophical subfields. Unfortunately, work focused exclusively on the nature of luck is in short supply on the contemporary analytic scene. In his highly impressive recent book Epistemic Luck, Duncan Pritchard helps rectify this neglect by presenting a partial account of luck that he uses to illuminate various ways luck can figure in cognition. In this paper, I critically evaluate both Pritchard’s account of luck and another account to which Pritchard’s discussion draws our attention—viz., that (...) due to Nicholas Rescher. I also assess some novel analyses of luck that incorporate plausible elements of Pritchard’s and Rescher’s accounts. (shrink)

Where does the mind stop and the rest of the world begin? The question invites two standard replies. Some accept the demarcations of skin and skull, and say that what is outside the body is outside the mind. Others are impressed by arguments suggesting that the meaning of our words "just ain't in the head", and hold that this externalism about meaning carries over into an externalism about mind. We propose to pursue a third position. We advocate a very different (...) sort of externalism: an _active externalism_, based on the active role of the environment in driving cognitive processes.

Robust Virtue Epistemology maintains that knowledge is achieved just when an agent gets to the truth through, or because of, the manifestation of intellectual virtue or ability. A notorious objection to the view is that the satisfaction of the virtue condition will be insufficient to ensure the safety of the target belief; that is, RVE is no anti-luck epistemology. Some of the most promising recent attempts to get around this problem are considered and shown to ultimately fail. Finally, a new (...) proposal for defending RVE as a kind of anti-luck epistemology is defended. The view developed here turns importantly on the idea that knowledge depends on ability and luck in a way that is gradient, not rigid, and that we know just when our cognitive success depends on ability not rather, but more so, than luck.

In “Knowledge Under Threat” (Philosophy and Phenomenological Research 2012), Tomas Bogardus proposes a counterexample to the safety condition for knowledge. Bogardus argues that the case demonstrates that unsafe knowledge is possible. I argue that the case just corroborates the well-known requirement that modal conditions like safety must be relativized to methods of belief formation. I explore several ways of relativizing safety to belief-forming methods and I argue that none is adequate: if methods were individuated in those ways, safety would fail (...) to explain several much-discussed cases. I then propose a plausible externalist principle of method individuation. On the one hand, relativizing safety to belief-forming methods in the way suggested allows the defender of safety to account for the cases. On the other hand, it shows that the target known belief of Bogardus’s example is safe. Finally, I offer a diagnosis of a common error about the kind of cases that are typically considered potential counterexamples to the necessity of the epistemic condition: proponents of the alleged counterexamples mistake a strong condition that I call super-safety for safety.

In an essay recently published in this journal (“Is Safety in Danger?”), Fernando Broncano-Berrocal defends the safety condition on knowledge from a counterexample proposed by Tomas Bogardus (Philosophy and Phenomenological Research, 2012). In this paper, we will define the safety condition, briefly explain the proposed counterexample, and outline Broncano-Berrocal’s defense of the safety condition. We will then raise four objections to Broncano-Berrocal’s defense, four implausible implications of his central claim. In the end, we conclude that Broncano-Berrocal’s defense of the safety (...) condition is unsuccessful, and that the safety condition on knowledge should be rejected. (shrink)

Many contemporary epistemologists hold that a subject S’s true belief that p counts as knowledge only if S’s belief that p is also, in some important sense, safe. I describe accounts of this safety condition from John Hawthorne, Duncan Pritchard, and Ernest Sosa. There have been three counterexamples to safety proposed in the recent literature, from Comesaña, Neta and Rohrbaugh, and Kelp. I explain why all three proposals fail: each moves fallaciously from the fact that S was at epistemic risk (...) just before forming her belief to the conclusion that S’s belief was formed unsafely. In light of lessons from their failure, I provide a new and successful counterexample to the safety condition on knowledge. It follows, then, that knowledge need not be safe. Safety at a time depends counterfactually on what would likely happen at that time or soon after in a way that knowledge does not. I close by considering one objection concerning higher-order safety.

John Hawthorne is widely regarded as one of the finest philosophers working today. He is perhaps best known for his contributions to metaphysics, and this volume collects his most notable papers in this field. Hawthorne offers original treatments of fundamental topics in philosophy, including identity, ontology, vagueness, and causation. Six of the essays appear here for the first time, and there is a valuable introduction to guide the reader through the selection.

When we affirm that someone knows something, we are making a value judgment of sorts - we are claiming that there is something superior about that person's opinion, or their evidence, or perhaps about them. A central task of the theory of knowledge is to investigate the sort of evaluation at issue. This is the first book to make 'epistemic normativity,' or the normative dimension of knowledge and knowledge ascriptions, its central focus. John Greco argues that knowledge is a kind (...) of achievement, as opposed to mere lucky success. This locates knowledge within a broader, familiar normative domain. By reflecting on our thinking and practices in this domain, it is argued, we gain insight into what knowledge is and what kind of value it has for us. (shrink)

Almost all theories of knowledge and justified belief employ moral concepts and forms of argument borrowed from moral theories, but none of them pay attention to the current renaissance in virtue ethics.

This highly original work of philosophy for professionals will also provide students with an excellent introduction to epistemology, virtue theory, and the relationship between ethics and epistemology.
