This thesis is a defense of (a version of) moral perceptualism. Moral perceptualism (MP), as is generally understood, advocates the bold view that “moral properties can be perceptual content”; its supporters include Audi (2013, 2015), Lord (2018), McNaughton (1988), McBrayer (2010a, 2010b), Cowan (2015), and Werner (2016, 2020b). In support of MP, Werner (2016) bolsters what he calls ‘phenomenal contrast arguments(PCAs)’. According to PCAs, the best explanation for inter-subjective phenomenal contrast between two subjects facing the same moral situation is that (...) one subject has moral perceptual experience(s) of moral properties, whereas the other does not. If PCAs are sound, then MP can be justified (in that one subject does perceive moral properties). However, some powerful counterarguments against MP have been proposed by Väyrynen(2018), Reiland(2021), and Chudnoff(2015); each of them provides competing explanations for inter-subjective phenomenal contrast and argues that their explanations are more reasonable than PCAs. My purposes in this thesis are to ascertain (I) which explanation for inter-subjective phenomenal contrast is more reasonable; (II) (how) could moral perceptualists like Werner (2016, 2020b) properly reply to the counterarguments against MP？ Or is there any better alternative explanation that could support MP？ As regards (I), I will argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) alternative explanatory models for inter-subjective phenomenal contrast are not to be seen as competing explanations against the one provided by MP; rather, they are complementary to it. As regards (II), I argue that Väyrynen’s(2018), Reiland’s(2021), and Chudnoff's (2015) conterarguments against MP at most demonstrate that certain moral properties (e.g., rightness/ wrongness/goodness/badness) can’t be part of the perceptual content, but their arguments do not (or indeed cannot) rule out the possibility that moral salience can be properly construed as part of the perceptual content. In light of this, I argue that an alternative version of moral perceptualism, or what I call ‘moral salience perceptualism’, according to which “moral salience can be part of the perceptual content”, still remains alive and kicking in face of their counteraguments. Moreover, I argue that moral salience perceptualism is explanatorily superior to Werner’s (2016) version of MP in terms of explaining inter-subjective phenomenal contrast. -/- Keywords： moral perceptualism, phenomenal contrast, moral salience, moral experiences, moral judgments -/- .

Does utterance understanding require reliable (i.e. non-lucky) recovery of the speaker’s intended proposition? There are good reasons to answer in the affirmative: the role of understanding in supporting testimonial knowledge seemingly requires such reliability. Moreover, there seem to be communicative analogues of Gettier cases in which luck precludes the audience’s understanding an utterance despite recovering the intended proposition. Yet, there are some major problems with the view that understanding requires such reliability. Firstly, there are a number of cases in which (...) understanding seems to occur in a lucky way. In light of these cases I argue that we need to narrow down the precise sense in which understanding precludes luck – the anti-luck condition attached to linguistic understanding is importantly different to anti-luck conditions typically applied to knowledge. Secondly, Megan Hyska has recently argued that, assuming understanding precludes luck, we get a communicative analogue of the value problem for knowledge. i.e. why is it better to meet the other conditions for understanding in a reliable way than in a lucky way? It is natural to assume that we can simply port over our favoured responses to the epistemic value problem in response to Hyska’s challenge. I argue that, due to the difference between epistemic and communicative luck (discussed in response to the first problem), this cannot be done. The epistemic and communicative value problems will require different solutions. I close by sketching the beginnings of an alternative answer to the value problem for communication. (shrink)

The Cartesian arguments for external world skepticism are usually considered to be significant for at least two reasons: they seem to present genuine paradoxes and that providing an adequate response to these arguments would reveal something epistemically important about knowledge, justification, and/or our epistemic position to the world. Using only premises and reasoning the skeptic accepts, I will show that the most common Cartesian argument for external world skepticism leads to a previously unrecognized self-undermining dilemma: it either leads to a (...) reductio ad absurdum, or to avoid this reductio the skeptic must accept that this argument is epistemically idle—it does not provide any support for external world skepticism. Either way, this Cartesian argument cannot legitimately threaten or even call into question our beliefs about the external world. And thus, either way, this Cartesian argument for external world skepticism is not epistemically significant—it is not a genuine paradox and adequately responding to it need not reveal anything epistemically important. (shrink)

For several decades, renewed interest in the connection between perception and knowledge has sustained a robust debate over external world skepticism. Recently, however, a growing consensus claims the skeptical challenge has been substantially met, and that realism in some robust form has emerged a clear victor. I invite us to rethink this consensus in a two-part response. The first forges a temporary alliance with skepticism against prominent forms of contemporary realism. That these fail to rebuff ews bolsters Barry Stroud’s call (...) for a new paradigm of objectivity. In the second part I sketch such a paradigm based upon a transactional interpretation of John Dewey’s pragmatism, and indicate its resilience to skeptical attacks. (shrink)

Norman forms the belief that the president is in New York by way of a clairvoyance faculty he doesn’t know he has. Many agree that his belief is unjustified but disagree about why it is unjustified. I argue that the lack of justification cannot be explained by a higher-level evidence requirement on justification, but it can be explained by a no-defeater requirement. I then explain how you can use cognitive faculties you don’t know you have. Lastly, I use lessons from (...) the foregoing to compare Norman’s belief, formed by clairvoyance, with Sally’s theistic belief, formed by a sensus divinitatis. (shrink)

It is a commonly held view in contemporary epistemology that for having knowledge it is necessary to have an appropriately based belief, although numerous different views exist about when a belief’s base is appropriate. Broadly speaking, they all share the view that one can only have knowledge if the belief’s base is in some sense truth-related or tracking the truth. Baseless knowledge can then be defi ned as knowledge where the belief is acquired and sustained in a way that does (...) not track the truth. I will argue that rejecting baseless knowledge leads to controversial consequences. The problem increases if we consider contrasting persons who know because of appropriate belief forming processes but who fail to possess further epistemic virtues such as understanding. I will not argue which belief bases constitute a suffi cient condition for knowledge. Rather I will stress the point that the common assumption that an appropriate basing relation constitutes a necessary condition for knowledge has controversial consequences. (shrink)

This paper explains what’s wrong with a Hume-inspired argument for skepticism about induction. Hume’s argument takes as a premise that inductive reasoning presupposes that the future will resemble the past. I explain why that claim is not plausible. The most plausible premise in the vicinity is that inductive reasoning from E to H presupposes that if E then H. I formulate and then refute a skeptical argument based on that premise. Central to my response is a psychological explanation for how (...) people judge that if E then H without realizing that they thereby settled the matter rationally. (shrink)

Recent literature has paid attention to a demarcation problem for evolutionary debunking arguments. This is the problem of asking in virtue of what regulative metaepistemic norm evolutionary considerations either render a belief justified, or debunk it as unjustified. I examine the so-called ‘Milvian Bridge principle’ A new science of religion, Routledge, New York, 2012; Sloan, McKenny, Eggelson Darwin in the 21st century: nature, humanity, and God, University Press, Notre Dame, 2015)), which offers exactly such a called for regulative metaepistemic norm. (...) The Milvian Bridge principle suggests that the metaepistemic norm is: adaptive reliability for truth of cognitive processes that the existence of corresponding truth-making facts evolutionary theory justifies. I argue that the Milvian Bridge principle is problematic on a number of counts, something that is shown via spiraling ‘companions in guilt arguments’. Finally, I consider ‘the core reductionist objection’ to the critique of the Milvian Bridge principle and offer a response. I conclude that the Milvian Bridge principle is destabilized. (shrink)

In this entry, I offer a critical analysis of virtue epistemology, which is a fundamental collection of recent approaches to epistemology. After a few remarks on the roots of this view, I reconstruct the key features of the two main accounts of virtue epistemology and I discuss how these accounts respond to some traditional epistemological challenges. -/- Questo contributo propone una disamina critica dell’epistemologia delle virtù, una delle correnti più importanti della teoria della conoscenza contemporanea.

According to process reliabilism, a belief produced by a reliable belief-forming process is justified. I introduce problems for this theory on any account of reliability. Does the performance of a process in some domain of worlds settle its reliability? The theories that answer “Yes” typically fail to state the temporal parameters of this performance. I argue that any theory paired with any plausible parameters has implausible implications. The theories that answer “No,” I argue, thereby lack essential support and exacerbate familiar (...) problems. There are new reasons to avoid any reliability conditions on justification. (shrink)

The paper provides a systematic overview of recent debates in epistemology and philosophy of science on the nature of understanding. We explain why philosophers have turned their attention to understanding and discuss conditions for “explanatory” understanding of why something is the case and for “objectual” understanding of a whole subject matter. The most debated conditions for these types of understanding roughly resemble the three traditional conditions for knowledge: truth, justification and belief. We discuss prominent views about how to construe these (...) conditions for understanding, whether understanding indeed requires conditions of all three types and whether additional conditions are needed. (shrink)

In this paper, I argue that, if transcendental arguments are to proceed from premises that are acceptable to the skeptic, the Transcendental Premise, according to which “X is a metaphysically necessary condition for the possibility of Y,” must be grounded in considerations of conceivability and possibility. More explicitly, the Transcendental Premise is based on what Szabó Gendler and Hawthorne call the “conceivability-possibility move.” This “inconceivability-impossibility” move, however, is a problematic argumentative move when advancing transcendental arguments for the following reasons. First, (...) from “S cannot conceive of P” it doesn’t necessarily follow that P is inconceivable. Second, from “P is inconceivable” it doesn’t necessarily follow that P is metaphysically impossible. Third, rather than block skeptical doubts, the conceivability-possibility move introduces skeptical doubts. For these reasons, transcendental arguments fail to deliver on their promise to overcome skeptical doubts. (shrink)

It is argued that a popular way of accounting for the distinctive value of knowledge by appeal to the distinctive value of cognitive achievements fails because it is a mistake to identify knowledge with cognitive achievements. Nevertheless, it is claimed that understanding, properly conceived, is a type of cognitive achievement, and thus that the distinctive value of cognitive achievements can explain why understanding is of special value.

It is held by some philosophers that it is possible that x has a disposition D but, if the stimulus condition obtains, it won’t manifest D because of an intrinsic interference. I will criticize this position on the ground that it has a deeply sceptical consequence, for instance, that, assuming that I am not well informed of the micro-properties of a metal coin, I do not know that it is not water-soluble. But I urge that this is beyond the pale, (...) especially in light of the weight of the practical considerations we take when we use dispositional concepts in everyday life or science. In doing so, further, I will formulate a type of belief-forming inference and claim that it confers justification on commonsensical dispositional beliefs like the one that a metal coin isn’t water-soluble.

This chapter first surveys general issues in the epistemic internalism / externalism debate: what is the distinction, what motivates it, and what arguments can be given on both sides. -/- The second part of the chapter will examine the internalism / externalism debate as regards to the specific case of the epistemology of memory belief.

It has become apparent that the debate between scientific realists and constructive empiricists has come to a stalemate. Neither view can reasonably claim to be the most rational philosophy of science, exclusively capable of making sense of all scientific activities. On one prominent analysis of the situation, whether we accept a realist or an anti-realist account of science actually seems to depend on which values we antecedently accept, rather than our commitment to “rationality” per se. Accordingly, several philosophers have attempted (...) to argue in favour of scientific realism or constructive empiricism by showing that one set of values is exclusively best, for anyone and everyone, and that the downstream choice of the philosophy of science which best serves those values is therefore best, for anyone and everyone. These efforts, however, seem to have failed. In response, I suggest that philosophers of science should suspend the effort to determine which philosophy of science is best for everyone, and instead begin investigating which philosophy of science is best for specific people, with specific values, in specific contexts. I illustrate how this might be done by briefly sketching a single case study from the history of science, which seems to show that different philosophies of science are better at motivating different forms of scientific practice.

Credit theories of knowledge have to explain the conditions under which beliefs are attributable to cognitive agents. The most promising way to explain these conditions is to offer an account of cognitive agency that is a plausible development of the uncontroversial notion that we are believing subjects. This article develops and defends a Structuralist model of cognitive agency.

The epistemological problem of the external world asks: (1) “How is knowledge of the external world possible given certain obstacles which make it look impossible?” This is a “how-possible?” question: it asks how something is possible given certain obstacles which make it look impossible (cf. Cassam 2007; Nozick 1981; Stroud 1984). Now consider the following question, which asks: (2) “How is a philosophically satisfying answer to (1) possible?” Skepticism is the thesis that knowledge of the external world is impossible. It (...) therefore represents a negative answer to the first question. Meta-epistemological skepticism is the thesis that a satisfying philosophical explanation of how our knowledge of the external world is possible is itself impossible. It therefore represents a negative answer to the second question. In this thesis, I explore the prospects of meta-epistemological skepticism. In particular, I structure the thesis around two master arguments from for meta-epistemological skepticism. The first argument is that skepticism represents a kind of paradox which requires dispensing with a plausible principle or belief, or even 'platitude', which means that there's no philosophically satisfying response to the paradox (see, e.g., Stroud 1984), and the second argument is “Stroud’s dilemma” (cf. Cassam 2009), that either we explain how external world knowledge is possible by reference to what external world knowledge we have, thereby failing to answer the philosophical question adequately, or else we don't, but then we succumb to first-order skepticism. I argue that the first argument fails to provide adequate support for meta-epistemological skepticism. However, the second argument, Stroud’s dilemma, is plausible and withstands serious objections (e.g., from Sosa 1994, Williams 1996, and Cassam 2009). In short, while the worry emerging out of the 'skeptical paradox' view fails to adequately support meta-epistemological skepticism, Stroud’s dilemma succeeds. Fortunately, it doesn't show that we lack external world knowledge; we rather just can't explain, philosophically, how it's possible. We may have first-order knowledge without understanding how it's possible. This thesis therefore represents a partial defense of meta-epistemological skepticism. Meta-epistemological skepticism is a live option in epistemology. (shrink)

According to proper functionalist theories of warrant, a belief is warranted only if it is formed by cognitive faculties that are properly functioning according to a good, truth-aimed design plan, one that is often thought to be specified either by intentional design or by natural selection. A formidable challenge to proper functionalist theories is the Swampman objection, according to which there are scenarios involving creatures who have warranted beliefs but whose cognitive faculties are not properly functioning, or are poorly designed, (...) or are not aimed at truth. In this paper, we draw lessons from cognitive science in order to develop a novel argument for the conclusion that the Swampman objection fails against proper functionalist theories of warrant. Our argument not only shows that the underlying, central intuition motivating Swampman-like scenarios is false but also motivates proper function as a necessary condition for warrant, thereby lending support to the claim that any theory of knowledge that lacks a proper function requirement is false.

In a recent article in this journal, Wolfgang Freitag argues that Gettier-style cases that are based on the notion of “distant” epistemic luck cannot be ruled out as cases of knowledge by modal conditions such as safety or sensitivity. I argue that safety and sensitivity can be easily fixed and that Freitag provides no convincing reason for the existence of “distant” epistemic luck.

It is sometimes claimed that conciliatory views on disagreement ultimately lead to either global or widespread scepticism. This is deemed to be a serious problem for conciliationism either because scepticism of either kind is a patently untenable stance or because it poses a serious threat to our intellectual and social lives. In this paper, I first argue that the alleged untenability of both types of scepticism is far from being obvious and should therefore be established rather than taken for granted, (...) and then that those who reject them because of the threat they pose surprisingly confuse pragmatic reasons with epistemic reasons. (shrink)

In this paper, I argue that arguments from skeptical hypotheses for external world skepticism derive their support from a skeptical argument from the distinction between appearance and reality. This skeptical argument from the appearance/reality distinction gives the external world skeptic her conclusion without appealing to skeptical hypotheses and without assuming that knowledge is closed under known entailments. If this is correct, then this skeptical argument from the appearance/reality distinction poses a new skeptical challenge that cannot be resolved by denying skeptical (...) hypotheses or knowledge closure.

A discussion of epistemic reasons, theoretical rationality, and the relationship between them. Discusses the ontology of reasons and evidence, the relationship between reasons (motivating, normative, possessed, apparent, genuine, etc.) and rationality, the relationship between epistemic reasons and evidence, the relationship between rationality, justification, and knowledge, and many other related topics.

Recent work in the psychology of happiness has led some to conclude that we are unreliable assessors of our lives and that skepticism about whether we are happy is a genuine possibility worth taking very seriously. I argue that such claims, if true, have worrisome implications for procreation. In particular, they show that skepticism about whether many if not most people are well positioned to create persons is a genuine possibility worth taking very seriously. This skeptical worry should not be (...) confused with a related but much stronger version of the argument, which says that all human lives are very bad and not worth starting. I criticize the latter stance, but take seriously the former stance and hope it can be answered in future work. (shrink)

Leading virtue epistemologists defend the view that knowledge must proceed from intellectual virtue and they understand virtues either as refned character traits cultivated by the agent over time through deliberate effort, or as reliable cognitive abilities. Philosophical situationists argue that results from empirical psychology should make us doubt that we have either sort of epistemic virtue, thereby discrediting virtue epistemology’s empirical adequacy. I evaluate this situationist challenge and outline a successor to virtue epistemology: abilism . Abilism delivers all the main (...) benefts of virtue epistemology and is as empirically adequate as any theory in philosophy or the social sciences could hope to be. (shrink)

Regulative virtue epistemology argues that intellectual virtues can adjust and guide one’s epistemic actions as well as improve on the quality of the epistemic actions. For regulative virtue epistemologists, intellectual virtues can be cultivated to a higher degree; when the quality of intellectual virtue is better, the resulting quality of epistemic action is better. The intellectual virtues that regulative epistemologists talk about are character virtues (such as intellectual courage and open-mindedness) rather than faculty virtues (such as sight and hearing), since (...) they don’t think that faculty virtues could be cultivated. This article refers to Xunzi’s philosophy, explaining how a regulative faculty-based virtue epistemology is possible. If this explanation works, on the one hand, a new branch of contemporary virtue epistemology is shown, and, on the other hand, a clear theoretical framework of Xunzi’s epistemology is constructed.

We commonly say that some evidence supports a hypothesis or that some premise evidentially supports a conclusion. Both internalists and externalists attempt to analyze this notion of evidential support, and the primary purpose of this paper is to argue that reliabilist and proper functionalist accounts of this relation fail. Since evidential support is one component of inferential justification, the upshot of this failure is that their accounts of inferential justification also fail. In Sect. 2, I clarify the evidential support relation. (...) In Sects. 3–5, I subject reliabilist and proper functionalist accounts of evidential support to various counterexamples. In Sect. 6, I show that the most promising ways to address these counterexamples aren’t very promising. (shrink)

The problem of philosophical skepticism relates to the difficulty involved in underwriting the claim that we know anything of spatio-temporal reality. It is often claimed, in fact, that proper philosophical scrutiny reveals quite the opposite from what common sense suggests. Knowledge of external reality is thought to be even quite obviously denied to us as a result of the alleged fact that we all fail to know that certain skeptical scenarios do not obtain. A skeptical scenario is one in which (...) we have neurological occurrences just like any normal situation in which we actually perceive spatio-temporal objects, but where we are deceived in some sense as a result of the manipulation of our brains from some outside source. In this work I attempt to address the problem of philosophical skepticism by claiming that most of us are able to come to know plenty about external reality, since we can come to realize that a certain philosophical theory of perception is correct. The theory I have in mind is what I call a non-cognitive theory of perception. According to this view, perceptual experience is defined by continuous, sensitive behavioral interaction with spatio-temporal objects of the appropriate size, shape, hardness, speed, etc. Knowing that this theory of perception is correct is equivalent to knowing that we know plenty about external reality. This is ultimately because by knowing that a non-cognitive theory of perception is true, we know that any skeptical scenario must fail to obtain. The structure of the work proceeds by first discussing the significance of the problem of philosophical skepticism in some detail. Chapter 1 lays out how the problem does indeed forcefully arise if it is conceded that we fail to know that the skeptical scenarios fail to obtain. Chapter 2 develops the sort of view of our epistemological situation that falls out of accepting without qualification that the problem exists. Chapter 3 examines and criticizes certain popular responses to the skeptical problem. The main goal of these first three preliminary chapters is to indicate that once it is admitted that we fail to know that the skeptical scenarios fail to obtain, the problem of philosophical skepticism forcefully presents itself. Chapter 4, however, attacks the idea that we fail to know that the skeptical scenarios fail to obtain. In this chapter I argue that this idea is wedded to the position that a certain theory of perception is correct. The theory in question is what I call a conjunctive theory of veridical experience. According to this view, normal experience of spatio-temporal objects occurs when a subject has a certain perceptual experience, and that experience also happens to match up with and/or be satisfied by what is really the case. Only when a theory of this sort is assumed, I argue, is the claim that we fail to know that the skeptical scenarios fail to obtain found to be obvious. In chapter 5 I argue that, in fact, a non-cognitive theory, rather than a conjunctive theory, is the correct view to maintain. In the final chapter 6 I develop the epistemological position that falls out of accepting a non-cognitive theory. (shrink)

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)

This paper defends the epistemological doctrine of fallibilism from recent objections. In “The Myth of Knowledge” Laurence BonJour argues that we should reject fallibilism for two main reasons: first, there is no adequate way to specify what level of justification is required for fallible knowledge; second, we cannot explain why any level of justification that is less than fully conclusive should have the significance that makes knowledge valuable. I will reply to these challenges in a way that allows me to (...) make progress on a number of important issues in contemporary epistemology: epistemic value, the functional roles of knowledge attributions, experimental epistemology, skepticism, the Gettier problem, and the lottery paradox. My argument is motivated by appealing to various insights derived from the method of ‘practical explication’, particularly the idea that a central purpose of the concept of knowledge is to flag reliable informants. My conclusion is that various practical and theoretical considerations derived from the method of practical explication support the fallibilist conception of knowledge. (shrink)

Consider the following proposition: It is possible that all of our perceptual experiences are ‘delusive.’ According to Gilbert Ryle, is demonstrably absurd. In this paper I address four questions: What is Ryle’s argument against?; How persuasive is it?; What positions are ruled out if is absurd?; and How does Ryle’s position compare with contemporary work on skepticism?

While there is now considerable anxiety about whether the psychological theory presupposed by virtue ethics is empirically sustainable, analogous issues have received little attention in the virtue epistemology literature. This paper argues that virtue epistemology encounters challenges reminiscent of those recently encountered by virtue ethics: just as seemingly trivial variation in context provokes unsettling variation in patterns of moral behavior, trivial variation in context elicits unsettling variation in patterns of cognitive functioning. Insofar as reliability is a condition on epistemic virtue, (...) we have reason to doubt that human beings possess the cognitive materials required for epistemic virtue, and thereby reason to think that virtue epistemology is threatened by skepticism. We conclude that while virtue epistemology has resources for addressing this challenge, exploiting these resources forces tradeoffs between empirical and normative adequacy. (shrink)

This chapter examines an evidentialist ethics of belief, and W. K. Clifford’s proposal in particular. It argues that regardless of how one understands the notion of evidence, it is implausible that we could have a moral obligation to refrain from believing something whenever we lack sufficient evidence. Alternatively, this chapter argues that there are wide-scope conditional requirements on beliefs but that these requirements can be met without having sufficient evidence for the belief in question. It then argues that we are (...) epistemically, though not morally, required to form epistemically valuable beliefs. However, these beliefs, too, need not be beliefs for which we have sufficient evidence—epistemically good beliefs need not be based on sufficient evidence. (shrink)

Defenders of pragmatic encroachment in epistemology (or what I call practicalism) need to address two main problems. First, the view seems to imply, absurdly, that knowledge can come and go quite easily—in particular, that it might come and go along with our variable practical interests. We can call this the stability problem. Second, there seems to be no fully satisfying way of explaining whose practical interests matter. We can call this the “whose stakes?” problem. I argue that both problems can (...) be addressed in roughly the same terms. More exactly, I argue that by first clarifying the whose stakes? problem an answer to the stability problem naturally falls out. (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)

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.

This volume brings together papers by some of the leading figures working on virtue-theoretic accounts in both ethics and epistemology. A collection of cutting edge articles by leading figures in the field of virtue theory including Guy Axtell, Julia Driver, Antony Duff and Miranda Fricker.

This paper explores the ramifications of the extended cognition thesis in the philosophy of mind for contemporary epistemology. In particular, it argues that all theories of knowledge need to accommodate the ability intuition that knowledge involves cognitive ability, but that once this requirement is understood correctly there is no reason why one could not have a conception of cognitive ability that was consistent with the extended cognition thesis. There is thus, surprisingly, a straightforward way of developing our current thinking about (...) knowledge such that it incorporates the extended cognition thesis. (shrink)

In this paper, I propose a virtue-theoretic approach to semantics, according to which the study of linguistic competence in particular, and the study of meaning and language in general, should focus on a speaker's interpretative virtues, such as charity and interpretability, rather than the speaker's knowledge of rules. The first part of the paper proffers an argument for shifting to virtue semantics, and the second part outlines the nature of such virtue semantics.

Two theses figure centrally in work on the epistemology of disagreement: Equal Weight (‘EW’) and Uniqueness (‘U’). According to EW, you should give precisely as much weight to the attitude of a disagreeing epistemic peer as you give to your own attitude. U has it that, for any given proposition and total body of evidence, some doxastic attitude is the one the evidence makes rational (justifies) toward that proposition. Although EW has received considerable discussion, the case for U has not (...) been critically evaluated. Endorsing U, we argue, commits one to the highly controversial thesis that whatever fixes your rational attitudes can do so only by fixing what evidence you have. This commitment imposes a relatively demanding requirement on justified belief in U, one that we argue is not satisfied by what is currently the strongest available case for U, due to Roger White [2005]. Our challenge to U makes more trouble for its proponents than do the worries about U expressed by Gideon Rosen [2001] and Thomas Kelly [2010]. Moreover, if Kelly [2010] is correct in thinking that EW “carries with it a commitment to” U—a claim which we accept for reasons similar to Kelly’s but is beyond this paper’s scope (but see Ballantyne and Coffman [forthcoming])—then our challenge to U bears importantly on EW: to the extent that our challenge to U succeeds, EW also suffers.

It is argued that it is beneficial to view the debate regarding radical scepticism through the lens of epistemic value. In particular, it is claimed that we should regard radical scepticism as aiming to deprive us of an epistemic standing that is of special value to us, and that this methodological constraint on our dealings with radical scepticism potentially has important ramifications for how we assess the success of an anti-sceptical strategy.

What are the qualities of an excellent thinker? A growing new field, virtue epistemology, answers this question. Section I distinguishes virtue epistemology from belief-based epistemology. Section II explains the two primary accounts of intellectual virtue: virtue-reliabilism and virtue-responsibilism. Virtue-reliabilists claim that the virtues are stable reliable faculties, like vision. Virtue-responsibilists claim that they are acquired character traits, like open-mindedness. Section III evaluates progress and problems with respect to three key projects: explaining low-grade knowledge, high-grade knowledge, and the individual intellectual virtues.

The sceptic about the external world presents us with a paradox: an apparently acceptable argument for an apparently unacceptable conclusion—that we do not know anything about the external world. Some paradoxes, for instance the liar and the sorites, are very hard. The defense of a purported solution to either of these two inevitably deploys the latest in high-tech philosophical weaponry. On the other hand, some paradoxes are not at all hard, and may be resolved without much fuss. They do not (...) contain profound lessons about the human condition. Where should we place the sceptical paradoxes? (shrink)

This paper argues that the best way to think about intellectual norms, or an ethics of belief, is by reflecting on the virtues and vices of inquiry. A theory of intellectual virtue provides a promising framework for evaluating different practices of inquiry in relation to the generic aim of truth. However, intellectual virtues are too often conflated with measures of reliability in mainstream epistemology, resulting in an overly narrow conception of epistemic value. Prominent reliabilists such as Alvin Goldman state that (...) a practice of inquiry is virtuous just in case it maximizes true belief. I argue that this reliabilist interpretation of virtue lacks the resources to explain evaluative distinctions between ways of maximizing true belief, such as the difference between maximizing accuracy and maximizing precision. With the aid of examples, I show that praiseworthy attributions of reliability are parasitic on attributions of topic-specific aims and skills that constitute their own characteristic standards of success, suggesting that bare truth-maximization is not the fundamental criterion of epistemic value. To accommodate the full range of intellectual norms that shape our practices, I conclude that we need a concept of virtue thicker than mere reliability. (shrink)

There are a number of relevant alternatives accounts of knowledge in the literature, including those by contextualists (like Lewis and Cohen), and invariantists (like Dretske). Despite widespread discussion of such views, an explication of the notion of relevance is conspicuously absent from the literature. Without a careful explication of that notion, relevant alternatives accounts resist evaluation. This paper attempts to aid in the evaluation of those accounts, by providing an account of relevance. The account rejects two common presuppositions about the (...) notion of relevance. The account holds that worlds, rather than alternatives, are relevant, and that distant worlds can be relevant. Relevant worlds turn out to be those worlds at which an alternative to one’s belief obtains, and is such that one’s epistemic position (with respect to what one believes at the actual world) is worse than it is at the actual world.

Recent literature in epistemology has focused on the following argument for skepticism (SA): I know that I have two hands only if I know that I am not a handless brain in a vat. But I don't know I am not a handless brain in a vat. Therefore, I don't know that I have two hands. Part I of this article reviews two responses to skepticism that emerged in the 1980s and 1990s: sensitivity theories and attributor contextualism. Part II considers (...) the more recent ‘neo-Moorean’ response to skepticism and its development in ‘safety’ theories of knowledge. Part III argues that the skeptical argument set out in SA is not of central importance. Specifically, SA is parasitic on skeptical reasoning that is more powerful and more fundamental than that displayed by SA itself. Finally, Part IV reviews a Pyrrhonian argument for skepticism that is not well captured by SA, and considers a promising strategy for responding to it. (shrink)

A Série Investigação Filosófica é uma série de livros de traduções de verbetes da Enciclopédia de Filosofia da Stanford (Stanford Encyclopedia of Philosophy) e de outras plataformas internacionalmente reconhecidas, que intenciona servir tanto como material didático para os professores das diferentes sub-áreas e níveis da Filosofia quanto como material de estudo para a pesquisa e para concursos da área. Nós, professores, sabemos o quão difícil é encontrar bom material em português para indicarmos. E há uma certa deficiência na graduação brasileira (...) de filosofia, principalmente em localizações menos favorecidas, com relação ao conhecimento de outras línguas, como o inglês e o francês. Tentamos, então, suprir essa deficiência, ao introduzirmos essas traduções ao público de língua portuguesa, sem nenhuma finalidade comercial e meramente pela glória da filosofia. (shrink)
