The previous chapter offers a distinctive virtue-theoretic account of knowledge, which the chapter describes as dispositional robust virtue epistemology. It is argued that this view is ultimately untenable because it cannot accommodate what we refer to as the epistemic dependence of knowledge. This point is motivated by employing what we call an epistemic Twin Earth argument, and also by appealing to some familiar claims in the epistemology of testimony. In addition, it is claimed that there is an alternative proposal available, (...) which we refer to as anti-luck virtue epistemology, that can accommodate epistemic dependence and which can thus offer a more satisfactory account of knowledge.

There is a virtual consensus in contemporary epistemology that knowledge must be reliably produced. Everyone, it seems, is a reliabilist about knowledge in that sense. I present and defend two arguments that unreliable knowledge is possible. My first argument proceeds from an observation about the nature of achievements, namely, that achievements can proceed from unreliable abilities. My second argument proceeds from an observation about the epistemic efficacy of explanatory inference, namely, that inference to the best explanation seems to produce knowledge, (...) even if it isn't reliable. I also propose a successor to standard versions of reliabilism, which I call ‘ecumenical reliabilism’. Ecumenical reliabilism is consistent with unreliably produced knowledge and helps explain why unreliably produced knowledge is possible. (shrink)

In this book, Ernest Sosa explains the nature of knowledge through an approach originated by him years ago, known as virtue epistemology. Here he provides the first comprehensive account of his views on epistemic normativity as a form of performance normativity on two levels. On a first level is found the normativity of the apt performance, whose success manifests the performer's competence. On a higher level is found the normativity of the meta-apt performance, which manifests not necessarily first-order skill or (...) competence but rather the reflective good judgment required for proper risk assessment. Sosa develops this bi-level account in multiple ways, by applying it to issues much disputed in recent epistemology: epistemic agency, how knowledge is normatively related to action, the knowledge norm of assertion, and the Meno problem as to how knowledge exceeds merely true belief. A full chapter is devoted to how experience should be understood if it is to figure in the epistemic competence that must be manifest in the truth of any belief apt enough to constitute knowledge. Another takes up the epistemology of testimony from the performance-theoretic perspective. Two other chapters are dedicated to comparisons with ostensibly rival views, such as classical internalist foundationalism, a knowledge-first view, and attributor contextualism. The book concludes with a defense of the epistemic circularity inherent in meta-aptness and thereby in the full aptness of knowing full well. (shrink)

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)

According to a captivating picture, epistemic justification is essentially a matter of epistemic or evidential likelihood. While certain problems for this view are well known, it is motivated by a very natural thought—if justification can fall short of epistemic certainty, then what else could it possibly be? In this paper I shall develop an alternative way of thinking about epistemic justification. On this conception, the difference between justification and likelihood turns out to be akin to the more widely recognised difference (...) between ceteris paribus laws and brute statistical generalisations. I go on to discuss, in light of this suggestion, issues such as classical and lottery-driven scepticism as well as the lottery and preface paradoxes. (shrink)

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)

I contrast two approaches to the interpretation of generics such as ‘ravens are black:’ majority-based views, on which they are about what is the case most of the time, and inquiry-based views, on which they are about a feature we focus on in inquiry. I argue that majority-based views face far more systematic counterexamples than has previously been supposed. They cannot account for generics about kinds with multiple characteristic properties, such as ‘elephants live in Africa and Asia.’ I then go (...) on to sketch an inquiry-based view. (shrink)

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)

Objections to reliabilist theories of knowledge and justification have looked insuperable. Reliability is a property of the process of belief formation. But the generality problem apparently makes the specification of any such process ambiguous. The externalism of reliability theories clashes with strongly internalist intuitions. The reliability property does not appear closed under truth-preserving inference, whereas closure principles have strong intuitive appeal. And epistemic paradoxes, like the preface and the lottery, seem unavoidable if knowledge or justification depends on the frequency with (...) which a process generates true beliefs. The present theory has the conceptual resources to meet these challenges. It requires that a justificatory belief-formation process be intentionally applied. It distinguishes the justification of beliefs from that of the believer. And it avoids a frequency interpretation of reliability by introducing a notion of the normalcy of conditions under which processes are intentionally used. (shrink)

In this paper, I critically examine the two dominant views of the concept of luck in the current literature: lack of control accounts and modal accounts. In particular, I argue that the conditions proposed by such views—that is, a lack of control and the absence of counterfactual robustness—are neither necessary nor sufficient for an event's being lucky. Hence, I conclude that the two main accounts in the current literature both fail to capture what is distinctive of, and central to, the (...) concept of luck. (shrink)

A view of knowledge—what I call the "Deserving Credit View of Knowledge" —found in much of the recent epistemological literature, particularly among so-called virtue epistemologists, centres around the thesis that knowledge is something for which a subject deserves credit. Indeed, this is said to be the central difference between those true beliefs that qualify as knowledge and those that are true merely by luck—the former, unlike the latter, are achievements of the subject and are thereby creditable to her. Moreover, it (...) is often further noted that deserving credit is what explains the additional value that knowledge has over merely lucky true belief. In this paper, I argue that the general conception of knowledge found in the DCVK is fundamentally incorrect. In particular, I show that deserving credit cannot be what distinguishes knowledge from merely lucky true belief since knowledge is not something for which a subject always deserves credit. (shrink)

It is widely assumed that memory has only the capacity to preserve epistemic features that have been generated by other sources. Specifically, if S knows (justifiedly believes/rationally believes) that p via memory at T2, then it is argued that (i) S must have known (justifiedly believed/rationally believed) that p when it was originally acquired at Tl, and (ii) S must have acquired knowledge that p (justification with respect to p/rationality with respect to p) at Tl via a non-memorial source. Thus, (...) according to this view, memory cannot make an unknown proposition known, an unjustified belief justified, or an irrational belief rational--it can only preserve what is already known, justified, or rational. In this paper, I argue that condition (i) is false and, a fortiori, that condition (ii) is false. Hence, I show that, contrary to received wisdom in contemporary epistemology, memory can function as a generative epistemic source. (shrink)

According to virtue epistemology, knowledge involves cognitive success that is due to cognitive competence. This paper explores the prospects of a virtue theory of knowledge that, so far, has no takers in the literature. It combines features from a couple of different virtue theories: like Pritchard's [forthcoming; et al. 2010] view, it qualifies as what I call an ‘impure’ version of virtue epistemology, according to which the competence condition is supplemented by an additional condition; like Sosa's 2007, 2010 view, it (...) construes the ‘because’ relation at issue in the competence condition in terms of competence manifestation. I argue that this virtue epistemology can steer clear of a number of old and new problems that arise for its rivals on both sides. (shrink)

A common presupposition in epistemology is that the processes contributing to the generation of knowledge do not extend beyond the knower's skin. This paper challenges this presupposition. I adduce a novel kind case that causes trouble for a number of even the most promising accounts of knowledge in current literature, at least so long as the presupposition is in place. I then look at a couple of recent accounts of knowledge that drop the presupposition and expressly allow the relevant processes (...) to extended beyond the knower's skin. While these accounts can handle the problem case, they encounter difficulties elsewhere: extension occurs too easily and so the accounts predict knowledge where they ought not. Finally, I offer a novel way of extending epistemology and argue that it can steer clear of the problems on both sides. (shrink)

A popular form of virtue epistemology—defended by such figures as Ernest Sosa, Linda Zagzebski and John Greco—holds that knowledge can be exclusively understood in virtue-theoretic terms. In particular, it holds that there isn't any need for an additional epistemic condition to deal with the problem posed by knowledge-undermining epistemic luck. It is argued that the sustainability of such a proposal is called into question by the possibility of epistemic twin earth cases. In particular, it is argued that such cases demonstrate (...) the need for virtue-theoretic accounts of knowledge to appeal to an independent epistemic condition which excludes knowledge-undermining epistemic luck. (shrink)

The claim that knowledge is a kind of success from ability has great theoretical power: it explains the nature of epistemic normativity, why knowledge is incompatible with luck, and why knowledge is more valuable than mere true belief. This paper addresses objections to the view by wedding it with two additional ideas: that intellectual abilities display a certain structure, and that the concept of knowledge functions to flag good information, and good sources of information, for use in practical reasoning.

This paper reviews two skeptical arguments and argues that a reliabilist framework is necessary to avoid them. The paper also argues that agent reliabilism, which makes the knower the seat of reliability, is the most plausible version of reliabilism.

The aim of this paper is to defend a novel characterization of epistemic luck. Helping myself to the notions of epistemic entitlement and adequate explanation, I propose that a true belief suffers from epistemic luck iff an adequate explanation of the fact that the belief acquired is true must appeal to propositions to which the subject herself is not epistemically entitled. The burden of the argument is to show that there is a plausible construal of the notions of epistemic entitlement (...) and adequate explanation on which the resulting characterization of epistemic luck, though admittedly programmatic, has several important virtues. It avoids difficulties which plague modal accounts of epistemic luck; it can explain the conflicting temptations one can feel in certain alleged cases of epistemic luck; it offers a novel account of the value of knowledge, without committing itself to any particular analysis of knowledge; and it illuminates the significance for epistemology of the phenomenon of epistemic luck itself.

There is, no doubt, a temptation to treat preventions, such as ‘the father’s grabbing the child prevented the accident’, and cases of ‘causation’ by omission, such as ‘the father’s inattention was the cause of the child’s accident’, as cases of genuine causation. I think they are not, and in this paper I defend a theory of what they are. More specifically, the counterfactual theory defended here is that a claim about prevention or ‘causation’ by omission should be understood not as (...) being directly about actual genuine causation but primarily as a counterfactual claim about genuine causation.1 The relation between actual causation and the mere possibility of causation allows my theory to explain both the difference and the similarity between the two notions (causation and prevention/omission). Further, the difference explains certain intuitions we have and the similarity justifies and explains the fact that for practical purposes we usually treat preventions and omissions as if they were genuine causation. Finally, the fact that this counterfactual theory of prevention and omission takes causation as primitive suggests that it is consistent with any theory of causation. This allows us to construct two arguments against what I will call genuinism, the view that cases of prevention and ‘causation’ by omission really are cases of genuine causation. In section II I show that genuinism does not account for the so-called intuition of difference. In section III I outline a number of problems that various theories of causation have with preventions and ‘causation’ by omission. These problems are ipso facto problems for genuinism, whereas I show in section V how the counterfactual theory solves those problems. Further, I answer a genuinist argument based on another type of intuition—the genuinist intuition—by showing why we have that intuition and how it should be handled (section VI). (shrink)

Ernest Sosa has argued that if someone knows that p, then his belief that p is “safe”. and Timothy Williamson has agreed. In this paper I argue that safety, as defined by Sosa, is not a necessary condition on knowledge – that we can have unsafe knowledge. I present Sosa’s definition of safety and a counterexample to it as a necessary condition on knowledge. I also argue that Sosa’s most recent refinements to the notion of safety don’t help him to (...) avoid the counterexample. I consider three replies on behalf of the defender of safety, and find them all wanting. Finally, I offer a tentative diagnosis of my counterexample. (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. (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. (shrink)

In this article, I offer a new analysis of knowledge: knowledge, I claim, is normal belief. I begin with what I take to be the conceptual truth that knowledge is epistemically justified, or permissible, belief. I then argue that this in turn is simply doxastically normal belief, first clarifying what is meant by this claim, and then providing reasons to think that normal belief, so understood, must be true and safe from error, making it a good candidate for knowledge.

Bernhard Nickel presents a theory of generic sentences and the kind-directed modes of thought they express. The theory closely integrates compositional semantics with metaphysics to solve the problem that generics pose: what do generics mean? Generic sentences are extremely simple, yet if there are patterns to be discerned in terms of which are true and which are false, these patterns are subtle and complex. Ravens are black, and lions have manes: statistical measures cannot do justice to the facts, but what (...) else is there that has a hope of giving us insight into what we are capturing across so many domains? Nickel argues that generics are the top of a fundamentally explanatory iceberg, and that this explanatory framework is deeply intertwined with the semantics of the language we use to express them. In providing an integrated semantic and metaphysical theory of generics, he aims to solve old puzzles and draw attention to new phenomena. (shrink)

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.

This book proposes an original theory of epistemic justification that offers a new way to relate justification to the epistemic goal of truth-conducive belief.

Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment.

The paper begins by reviewing two problems for fallibilism: the lottery problem, or the problem of explaining why fallible evidence, though otherwise excellent, is not enough to know that one will lose the lottery, and Gettier problems. It is then argued that both problems can be resolved if we note an important illocutionary force of knowledge attributions: namely, that when we attribute knowledge to someone we mean to give the person credit for getting things right. Alternatively, to say that a (...) person knows is to say that she got things right due to her own abilities, efforts and actions, rather than due to dumb luck, or blind chance, or something else.

In previous work I have argued that talk about negative events should not be taken at face value: typically, what we are inclined to think of as a negative event (John’s failure to go jogging) is just an ordinary, positive event (his going to the movie instead); it is a positive event under a negative description. Here I consider more closely the difficulties that arise in those cases where no positive event seems available to do the job, as with putative (...) cases of causation by omission. In particular, I elaborate on Helen Beebee’s idea that not all causal explanations are reports of causation. When we mention John’s failure to turn off the gas as an explanans of why there was an explosion, we do not say what caused the explosion. We do not mention any of the relevant causes. We just remark that one sort of event that was supposed to occur, and whose occurrence would have prevented the explosion, did not in fact occur. (shrink)

In my remarks, I discuss Sosa's attempt to deal with the sceptical threat posed by dreaming. Sosa explores two replies to the problem of dreaming scepticism. First, he argues that, on the imagination model of dreaming, dreaming does not threaten the safety of our beliefs. Second, he argues that knowledge does not require safety, but a weaker condition which is not threatened by dreaming skepticism. I raise questions about both elements of his reply.

This paper provides a principled and elegant solution to the Gettier problem. The key move is to draw a general metaphysical distinction and conscript it for epistemological purposes. Section 1 introduces the Gettier problem. Sections 2–5 discuss instructively wrong or incomplete previous proposals. Section 6 presents my solution and explains its virtues. Section 7 answers the most common objection.
