In this paper, we contend that the “Smith case” in Gettier’s attempt to refute the justified true belief (JTB) account of knowledge does not work. This is because the said case fails to satisfy the truth condition, and thus is not a case of JTB at all. We demonstrate this claim using the framework of Donnellan’s distinction between the referential and attributive uses of definite descriptions. Accordingly, the truth value of Smith’s proposition “The man who will get the job has (...) ten coins in his pocket” partly depends on how Smith uses the definite description “the man who will get the job” when he utters the proposition. Since, upon uttering the proposition, Smith has in mind a particular individual, namely Jones, and not just whoever will fit the attribute specified in the definite description, Smith uses the definite description referentially. And so when it turns out that it is Smith who eventually gets the job, the definite description fails to refer to Jones as intended by Smith, thereby making Smith’s proposition false. To think that Smith’s proposition is still true, in this regard, is to use the definite description attributively—that it is about whoever will fit the definite description. Apparently, when Gettier claims that Smith’s proposition is still true, to demonstrate that it is a case of JTB, he, in effect, imposes his attributive understanding of Smith’s usage of the definite description on Smith’s own epistemic situation.

This is the most comprehensive book ever published on philosophical methodology. A team of thirty-eight of the world's leading philosophers present original essays on various aspects of how philosophy should be and is done. The first part is devoted to broad traditions and approaches to philosophical methodology. The entries in the second part address topics in philosophical methodology, such as intuitions, conceptual analysis, and transcendental arguments. The third part of the book is devoted to essays about the interconnections between philosophy (...) and neighbouring fields, including those of mathematics, psychology, literature and film, and neuroscience.

Wem wird geglaubt und wem nicht? Wessen Wissen wird weitergegeben und wessen nicht? Wer hat eine Stimme und wer nicht? Theorien der epistemischen Ungerechtigkeit befassen sich mit dem breiten Feld der ungerechten oder unfairen Behandlung, die mit Fragen des Wissens, Verstehens und Kommunizierens zusammenhängen, wie z.B. die Möglichkeit, vom Wissen oder von kommunikativen Praktiken ausgeschlossen zu werden oder zum Schweigen gebracht zu werden, aber auch Kontexte, in denen die Bedeutungen mancher systematisch verzerrt oder falsch gehört und falsch dargestellt werden, in (...) denen manchen misstraut wird oder es an epistemischer Handlungsfähigkeit mangelt. In diesem Buch wird eine Übersicht über die breite Debatte epistemischer Ungerechtigkeit, epistemischer Unterdrückung und epistemischer Gewalt gegeben, in dem unterschiedliche Theorien, die sich auf der Schnittstelle von Gerechtigkeitstheorie und epistemischen Fragen befinden, systematisch und kritisch diskutiert sowie theoretische Vorgänger dieser Theorien beleuchtet werden.

Edmund Gettier (1963) argued that there can be justified true belief (JTB) that is not knowledge. I question the correctness of his argument by showing that Smith of Gettier’s famous examples does not earn justification for his incidentally true beliefs, while a doxastically more conscientious person S would come to hold justified but false beliefs. So, Gettier’s (and analogous) cases do not result in justified _and_ true belief. This is due to a tension between deductive closure of justification and evidential (...) support. For being justified, any believing, disbelieving, or withholding of deductively inferred propositions must be distributed proportionally to given evidential support. This proportionality principle has primacy over deductive closure in case of conflict. My argument does not save the JTB-account. But, instead of merely referring to an intuition, it explains why subjects in Gettier situations do not earn knowledge. (shrink)

One leading account of justification comes from the evidentialist tradition. According to evidentialists, whether a doxastic attitude is justified depends on whether that attitude is supported by the believer’s evidence. This chapter assesses the prospects for evidentialism, focusing on the question of whether evidentialists can provide a satisfactory account of their key notions – evidence possession and evidential support – without helping themselves to the notion of justification.

Moderate invariantism is the orthodox semantics for knowledge attributions. In recent years it has fallen out of favour, in large part because it fails to explain why ordinary speakers have the intuition that some utterances of knowledge attributions are felicitous and others infelicitous in several types of cases. To address this issue moderate invariantists have developed a variety of what I call non-semantic theories which they claim account for the relevant felicity intuitions independently of moderate invariantist semantics. Some critics have (...) responded by arguing that these non-semantic theories are implausible for one or more of the following reasons: they do not have a basis in empirical data or established theory; they do not account for all of the relevant felicity intuitions; they are ad hoc; or they in fact explain too many felicity intuitions and thus undermine the...

The paper defends Cartesian skepticism by an argument relying on internalism and infallibilism. It argues that this sort of skepticism gives the best explanation of our intuitions and ordinary epistemic practices.

Paying attention to the inner workings of mathematicians has led to a proliferation of new themes in the philosophy of mathematics. Several of these have to do with epistemology. Philosophers of mathematical practice, however, have not (yet) systematically engaged with general (analytic) epistemology. To be sure, there are some exceptions, but they are few and far between. In this chapter, I offer an explanation of why this might be the case and show how the situation could be remedied. I contend (...) that it is only by conceiving the knowing subject(s) as embodied, fallible, and embedded in a specific context (along the lines of what has been done within social and feminist epistemology) that we can pursue an epistemology of mathematics sensitive to actual mathematical practice. I further suggest that this reconception of the knowing subject(s) does not force us to abandon the traditional framework of epistemology in which knowledge requires justified true belief. It does, however, lead to a fallible conception of mathematical justification that, among other things, makes Gettier cases possible. This shows that topics considered to be far removed from the interests of philosophers of mathematical practice might reveal to be relevant to them. (shrink)

Introduction to Philosophy: Epistemology engages first-time philosophy readers on a guided tour through the core concepts, questions, methods, arguments, and theories of epistemology—the branch of philosophy devoted to the study of knowledge. After a brief overview of the field, the book progresses systematically while placing central ideas and thinkers in historical and contemporary context. The chapters cover the analysis of knowledge, the nature of epistemic justification, rationalism vs. empiricism, skepticism, the value of knowledge, the ethics of belief, Bayesian epistemology, social (...) epistemology, and feminist epistemologies. Along the way, instructors and students will encounter a wealth of additional resources and tools: chapter learning outcomes, key terms, images of philosophers and related art, useful diagrams and tables, boxes containing excerpts and other supplementary material, questions for reflection, suggestions for further reading, and a glossary. For an undergraduate survey epistemology course, Introduction to Philosophy: Epistemology is ideal when used as a main text paired with primary sources and scholarly articles. For an introductory philosophy course, select book chapters are best used in combination with chapters from other books in the Introduction to Philosophy open textbook series (edited by Christina Hendricks).

This paper examines two objections to the infinitist theory of epistemic justification, namely “the finite mind objection” and “the distinction objection.” It criticizes Peter Klein’s response to the distinction objection and offers a more plausible response. It is then argued that this response is incompatible with Klein’s response to the finite mind objection. Infinitists, it would seem, cannot handle both objections when taken together.

Gettier presented the now famous Gettier problem as a challenge to epistemology. The methods Gettier used to construct his challenge, however, utilized certain principles of formal logic that are actually inappropriate for the natural language discourse of the Gettier cases. In that challenge to epistemology, Gettier also makes truth claims that would be considered controversial in analytic philosophy of language. The Gettier challenge has escaped scrutiny in these other relevant academic disciplines, however, because of its façade as an epistemological analysis. (...) This article examines Gettier's methods with the analytical tools of logic and analytic philosophy of language. (shrink)

In this article, I use Edmund Gettier’s Ten Coins hypothetical scenario to illustrate some reasoning errors in the use of definite descriptions. The Gettier problem, central as it is to modern epistemology, is first and foremost an argument, which Gettier (Analysis 23(6):121–123, 1963) constructs to prove a contrary conclusion to a widely held view in epistemology. Whereas the epistemological claims in the case have been extensively analysed conceptually, the strategies and tools from other philosophical disciplines such as analytic philosophy of (...) language, logic and argumentation that Gettier deploys in the case have scarcely received any attention. This work abstracts from the epistemological content and examines Gettier’s handling of the definite description involved, and how that affects the cogency of his argument. (shrink)

The paper analyzes the problem of interpretations of the Gettier problem. The author draws a distinction between counterexamples presented in Edmund Gettier’s article and Gettier-style cases, between the Gettier problem and general epistemological problem supposedly occurring in all or many Gettier-style cases. It is argued that in Gettier’s article there is a gap associated with an insufficiently defined concept of justification, which does not allow talking about Gettier problem without any explicit or implicit interpretation of his views on justification. Along (...) with this, it is indicated that the same concept of justification has strict features (deductive closure principle, non-factive justification and internalism), which do not allow arbitrary interpretations of the Gettier problem, and therefore we can say that some interpretations are closer to the text of a well-known article.

The Difference between Belief and Knowledge. The assumption that knowledge can be defined in terms of belief is considered to be mistaken. Since Gettier problems are shown to be misconstrued, the question cannot arise whether his conditions for knowledge are sufficient for claiming ``knowledge is justified true belief''. Ayers' conditions for knowledge in addition with a specific stipulation proof to be instructive for elaborating the differences between knowledge and belief.

It is often said, metaphorically, that belief "aims" at the truth. This paper proposes a normative interpretation of this metaphor. First, the notion of "epistemic norms" is clarified, and reasons are given for the view that epistemic norms articulate essential features of the beliefs that are subject to them. Then it is argued that all epistemic norms--including those that specify when beliefs count as rational, and when they count as knowledge--are explained by a fundamental norm of correct belief, which requires (...) that, if one considers a proposition at all, one should believe it if and only if it is true.

Recently, Timothy Williamson has argued that considerations about margins of errors can generate a new class of cases where agents have justified true beliefs without knowledge. I think this is a great argument, and it has a number of interesting philosophical conclusions. In this note I’m going to go over the assumptions of Williamson’s argument. I’m going to argue that the assumptions which generate the justification without knowledge are true. I’m then going to go over some of the recent arguments (...) in epistemology that are refuted by Williamson’s work. And I’m going to end with an admittedly inconclusive discussion of what we can know when using an imperfect measuring device. (shrink)

A recent focus on philosophical methodology has reinvigorated ordinary language philosophy with the contention that philosophical inquiry is better served by attending to the ordinary use of language. Taking cues from findings in the social sciences that deploy methods utilizing language, various ordinary language philosophers embrace a guiding mandate: that ordinary language usage is more reflective of our linguistic and conceptual competencies than standard philosophical methods. We analyze two hypotheses that are implicit in the research from which ordinary language approaches (...) take their cues. This pair of optimistic assumptions (a) bind word meanings to properties of their corresponding concepts and (b) regard language as a direct reflection of our underlying cognitive processes and competencies. Polysemy and pragmatics complicate each assumption. Because the ordinary language philosopher’s methodological mandate compels us to consider how individuals process the utterances they encounter in deciphering the communicative intentions of speakers, failing to attend to the import of polysemy and pragmatics in philosophical and empirical methods has the potential to frustrate the aims of their insightful mandate. The significance of those two complications is worked out with the case study of knowledge. (shrink)

In a Normal Case, a subject has a justified true belief that P and also knows that P. In a Gettier Case, a subject has a justified true belief that P but does not know that P. The received view (endorsed by Lycan and others) is that if one is in a Normal Case then one cannot know that he is not in a Gettier case. I argue that the received view is mistaken and I discuss the implications this has (...) on some other epistemological issues. (shrink)

Safety purports to explain why cases of accidentally true belief are not knowledge, addressing Gettier cases and cases of belief based on statistical evidence. However, problems arise for using safety as a condition on knowledge: safety is not necessary for knowledge and cannot always explain the Gettier cases and cases of statistical evidence it is meant to address. In this paper, I argue for a new modal condition designed to capture the non-accidental relationship between facts and evidence required for knowledge: (...) causal safety. I argue that possible errors in belief can be captured by accounting for deviations in causal relationships and that there is a natural way to characterize which causal errors are relevant in an epistemic situation. Using this, I develop a causal analogue to safety, where one’s belief in p is causally safe if it is true in all causally relevant worlds where one believes p. Causal safety, I argue, can better explain the cases safety is meant to address and can avoid the arguments raised against the necessity of safety. (shrink)

In the Meno, Phaedo, and Phaedrus, Plato outlines the controversial thesis of a priori knowledge that all learning is a form of recollection—anamnesis. He uses this as an argument for the immortality of the soul via reincarnation. Because of this latter claim, the thesis is widely mocked by contemporary evolutionarily-informed materialists. But we can safely reject the metaphysical claim without abandoning the insight of the epistemological one. And indeed, modern evolutionary theory can explain how learning—at least of the sort that (...) depends on certain a priori concepts—can be a kind of recollection. Through this metaphor, natural selection is a process by which information about the world is transmitted across time. When we learn by reasoning about a priori knowledge, then, we in an important sense rely on information in our genomes—if not our souls—information acquired by the process of natural selection—if not conscious acquisition. Thinking of a priori knowledge with the metaphor of anamnesis elucidates two essential features of the relationship between epistemology and ontology. First, it emphasizes that there is necessarily a time-delay between our a priori knowledge and the universe to which it bears a relationship, if any. Second, it clarifies that a priori knowledge is knowledge that enhances reproductive fitness—which could well be because it reflects ontology faithfully, but could as easily be a kind of innate nominalism.

How do people decide which claims should be considered mere beliefs and which count as knowledge? Although little is known about how people attribute knowledge to others, philosophical debate about the nature of knowledge may provide a starting point. Traditionally, a belief that is both true and justified was thought to constitute knowledge. However, philosophers now agree that this account is inadequate, due largely to a class of counterexamples (termed ‘‘Gettier cases’’) in which a person’s justified belief is true, but (...) only due to luck. We report four experiments examining the effect of truth, justification, and ‘‘Gettiering’’ on people’s knowledge attributions. These experiments show that: (1) people attribute knowledge to others only when their beliefs are both true and justified; (2) in contrast to contemporary philosophers, people also attribute knowledge to others in Gettier situations; and (3) knowledge is not attributed in one class of Gettier cases, but only because the agent’s belief is based on ‘‘apparent’’ evidence. These findings suggest that the lay concept of knowledge is roughly consistent with the traditional account of knowledge as justified true belief, and also point to a major difference between the epistemic intuitions of laypeople and those of philosophers.

This paper attempts three things. The first is a defense and the rest is a critical appraisal of a crucial notion involved in the defense. First, it argues that John Turri’s criticisms of Ernest Sosa’s virtue epistemological account of knowledge that it fails to rule out Gettier cases rest on a misconstrual of the “because of clause” which Sosa employs. Turri overlooks the notion of “success manifests competence” which is central to understand the “because of” clause. Thus, the position of (...) Sosa is defended from the criticisms of Turri. Secondly, it critically examines the notion of “success manifests competence” which is a crucial notion in Sosa’s account. It argues, unlike what Sosa seems to hold, some of the conditions which Sosa provides for “success manifests competence” are not necessary. It also clarifies, by agreeing with Sosa, that the conditions he provides are not sufficient for “success manifests competence.” Thirdly, it briefly argues that Sosa’s occasional insistence that complete competence should be present in the case of success manifests competence brings in certain internal tension in the account of Sosa. Thus, the paper defends Sosa’s position from the criticisms of Turri; but it also clarifies Sosa’s account as well as raises some criticisms to it. (shrink)

In response to widespread doubts among professional philosophers (Russell, Horwich, Dietrich, McGinn, Chalmers), Stoljar argues for a ‘reasonable optimism’ about progress in philosophy. He defends the large and surprising claim that ‘there is progress on all or reasonably many of the big questions.’ However, Stoljar’s caveats and admitted avoidance of historical evidence permits overlooking persistent controversies in philosophy of mind and cognitive science that are essentially unchanged since the 17th Century. Stoljar suggests that his claims are commonplace in philosophy departments (...) and, indeed, the evidence I adduce constitutes an indictment of the widely shared view among professional analytic philosophers.

When a belief has been influenced, in part or whole, by factors that, by the believer's own lights, do not bear on the truth of the believed proposition, we can say that the belief has been, in a sense, arbitrarily formed. Can such beliefs ever be rational? It might seem obvious that they can't. After all, belief, supposedly, “aims at the truth.” But many epistemologists have come to think that certain kinds of arbitrary beliefs can, indeed, be rational. In this (...) paper, I want to do two things. First, I want to show that the claim that arbitrary beliefs can be rational is inconsistent with the conjunction of two other attractive claims: one saying that rationality requires a certain kind of epistemic immodesty, and one saying that rationality forbids certain kinds of self-ascriptions of epistemic luck. Second, I want to evaluate different ways one might respond to this inconsistent triad. I won't defend any response in particular, but I'll draw out some notable costs and benefits of each response, which may help shed light on the question of whether arbitrary beliefs can be rational.

A growing number of authors defend putative examples of knowledge from falsehood (KFF), inferential knowledge based in a critical or essential way on false premises, and they argue that KFF has important implications for many areas of epistemology (whether evidence can be false, the Gettier debate, defeasibility theories of knowledge, etc.). I argue, however, that there is no KFF, because in any supposed example either the falsehood does not contribute to the knowledge or the subject lacks knowledge. In particular, I (...) show that if the subject actually has knowledge in putative KFF cases, then there is always a veridical evidential path meeting the basing conditions that accounts for her knowledge; if there is no such path, then the subject is in a type of Gettier case. All the recent arguments that rely on KFF are therefore based on a mistake. (shrink)

The so-called expertise defence against sceptical challenges from experimental philosophy has recently come under attack: there are several studies claiming to have found direct evidence that philosophers’ judgments in thought experiments are susceptible to erroneous effects. In this paper, we distinguish between the customary ‘immune experts’ version of the expertise defence and an ‘informed experts’ version. On the informed expertise defence, we argue, philosophers’ judgments in thought experiments could be preferable to those by the folk even if it were true (...) that philosophers’ judgments are no less immune to confounders than judgments by the folk are. We present results from an experimental study comparing philosophers and non-philosophers (n = 484), which support this version of the expertise defence. (shrink)

The received view says that possibility is the dual of necessity: a proposition is (metaphysically, logically, epistemically etc.) possible iff it is not the case that its negation is (metaphysically, logically, epistemically etc., respectively) necessary. This reading is usually taken for granted by modal logicians and indeed seems plausible when dealing with logical or metaphysical possibility. But what about epistemic possibility? We argue that the dual definition of epistemic possibility in terms of epistemic necessity generates tension when reasoning about non-idealized (...) agents and is a problem of concern for most hyperintensional epistemic logics that alleviate the problem of logical omniscience. The tension is particularly evident when knowledge is taken as a primitive to define other epistemic concepts, such as justification and belief, as done in the knowledge-first tradition. We propose a non-dual interpretation of epistemic possibility, employing a hyperintensionality filter similar to the one that makes the corresponding epistemic necessity operator hyperintensional. We employ the proposed semantics to model Stalnaker's belief as epistemic possibility of knowledge and provide a sound and complete axiomatization for a hyperintensional version of his bimodal logic of knowledge and belief.

The Gettier Problem (henceforth GP) is a milestone in contemporary epistemology. Half a century after the philosophical earthquake caused by the well-known Gettier article (1963), solutions continue to appear and the discussion resurfaces. Because we, like many, choose to adopt an optimistic stance towards the possibility of finding a plausible answer to the GP, in this paper we present an unconventional solution to solve it. Crucially, we argue that the only plausible and non-falsifiable definition of the propositional knowledge is the (...) one given by an “open” formula that contains a placeholder or a “variable” – on the third necessary condition – which takes a value according to which, depending on the circumstances, is necessary and sufficient for epistemic success.

Pure virtue epistemology faces the fake barn challenge. This paper explains how it can be met. Thus, it is argued that the thought experiment contains a hidden ambiguity concerning the visual ability typically ascribed to, or denied, fake barn subjects. Disambiguation shows fake barn subjects to have limited knowledge of the target proposition. This accords with a pure virtue-theoretic conception of knowledge that predicts and explains all the intuitions elicited by the thought experiment. As a result, the relationship between knowledge, (...) luck and ability is illuminated, and our epistemological theorizing improved. (shrink)

Moral disagreement is sometimes thought to pose problems for moral realism because it shows that we cannot achieve knowledge of the moral facts the realists posit. In particular, it is "fundamental" moral disagreement—that is, disagreement that is not due to distorting factors such as ignorance of relevant nonmoral facts, bad reasoning skills, or the like—that is supposed to generate skeptical implications. In this paper, we show that this version of the disagreement challenge is flawed as it stands. The reason is (...) that the epistemic assumptions it requires are incompatible with the possibility of fundamental disagreement. However, we also present an alternative reconstruction of the challenge that avoids the problem. The challenge we present crucially invokes the principle that knowledge requires "adherence". While that requirement is usually not discussed in this context, we argue that it provides a promising explanation of why disagreement sometimes leads to skepticism. (shrink)

This paper aims to counter the recent opinion that there is a peculiar epistemology in the reformed Church which made it negative to natural theology. First, it is shown that there was an early and unanimous adoption of natural theology as the culmination of physics and the beginning of metaphysics by the sixteenth and seventeenth century philosophers of good standing in the reformed Church. Second, it is argued that natural theology cannot be based on revelation, should not assume a peculiar (...) analysis of knowledge and must not pass over demonstration. (shrink)

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

This paper critically surveys 20 years of recent work on radical skepticism. It focuses on three key issues. First, it starts by exploring how philosophers have recently challenged our understanding of radical skeptical arguments. It then unpacks and critically evaluates some influential reactions to radical skepticism: structuralism, knowledge-first epistemology, epistemological disjunctivism, and hinge epistemology. Third, it explores some novel developments of pragmatism, like pragmatic skepticism, gauges its anti-skeptical import, and reflects on the ways in which radical skeptical epistemology and ethics (...) might meet.

The recent movement towards virtue–theoretic treatments of epistemological concepts can be understood in terms of the desire to eliminate epistemic luck. Significantly, however, it is argued that the two main varieties of virtue epistemology are responding to different types of epistemic luck. In particular, whilst proponents of reliabilism–based virtue theories have been focusing on the problem of what I call “veritic” epistemic luck, non–reliabilism–based virtue theories have instead been concerned with a very different type of epistemic luck, what I call (...) “reflective” epistemic luck. It is argued that, prima facie at least, both forms of epistemic luck need to be responded to by any adequate epistemological theory. The problem, however, is that one can best eliminate veritic epistemic luck by adducing a so–called safety–based epistemological theory that need not be allied to a virtue–based account, and there is no fully adequate way of eliminating reflective epistemic luck. I thus conclude that this raises a fundamental difficulty for virtue–based epistemological theories, on either construal. [ABSTRACT FROM AUTHOR]. (shrink)

A certain construal of the Gettier problem is offered, according to which this problem concerns the task of identifying the anti-luck condition on knowledge. A methodology for approaching this construal of the Gettier problem—anti-luck epistemology—is set out, and the utility of such a methodology is demonstrated. It is argued that a range of superficially distinct cases which are meant to pose problems for anti-luck epistemology are in fact related in significant ways. It is claimed that with these cases properly understood, (...) anti-luck epistemology is able to offer a suitable diagnosis of them which doesn’t threaten the necessity of the anti-luck condition for knowledge.

The growing literature on philosophical thought experiments has so far focused almost exclusively on the role of thought experiments in confirming or refuting philosophical hypotheses or theories. In this paper we draw attention to an additional and largely ignored role that thought experiments frequently play in our philosophical practice: some thought experiments do not merely serve as means for testing various philosophical hypotheses or theories, but also serve as facilitators for conceiving and articulating new ones. As we will put it, (...) they serve as ‘heuristics for theory discovery’. Our purpose in the paper is two-fold: to make a case that this additional role of thought experiments deserves the attention of philosophers interested in the methodology of philosophy; to sketch a tentative taxonomy of a number of distinct ways in which philosophical thought experiments can aid theory discovery, which can guide future research on this role of thought experiments.

One of the guiding ideas of virtue epistemology is to look at epistemological issue through the lens of practical philosophy. The Gettier Problem is a case in point. Virtue epistemologists, like Sosa and Greco, see the shortcoming in a Gettier scenario as a shortcoming from which performances in general can suffer. In this paper I raise some doubts about the success of this project. Looking more closely at practical philosophy, will, I argue, show that virtue epistemology misconceives the significance of (...) Gettier structures in the practical domain. (shrink)

Knowledge is factually grounded belief. This account uses the same ingredients as the traditional analysis—belief, truth, and justification—but posits a different relation between them. While the traditional analysis begins with true belief and improves it by simply adding justification, this account begins with belief, improves it by grounding it, and then improves it further by grounding it in the facts. In other words, for a belief to be knowledge, it's not enough that it be true and justified; for a belief (...) to be knowledge, it must be justified by the facts. This account solves the Gettier problem. Gettierized beliefs fall short of knowledge because, albeit true and justified, they are not grounded in the facts. This account also elucidates why knowledge attributions are sensitive to epistemic standards. It's because whether we take a belief to be grounded in the facts is sensitive to epistemic standards. (shrink)

Reasons rationalize beliefs. Reasons, when all goes well, turn true beliefs into knowledge. I am interested in the relationship between these aspects of reasons. Without a proper understanding of their relationship, the theory of knowledge will be less illuminating than it ought to be. I hope to show that previous accounts have failed to account for this relationship. This has resulted in a tendency to focus on justification rather than knowledge. It has also resulted in many becoming skeptical about the (...) prospects for an analysis of knowledge. The skepticism is misplaced and the tendency can be fixed without sacrificing any insights. The solution is to see how good reasons (in a sense to be articulated) are apparent (in a sense to be articulated) to the knowing subject. Once this claim is unpacked, we see that it is an illuminating analysis of knowledge in terms of distinct but intimately related aspects of epistemic assessment. It helps us see the value of knowledge (over and above true belief) and it affords us a unified, “reasons-first” metaepistemology. The resulting picture is neither a familiar kind of internalism or externalism. (shrink)

Epistemologists often remark that knowledge precludes luck. A true belief based on a guess or hunch is not knowledge because it seems merely fortuitous, too much of an accident, and, well, lucky that one happened to get things right. Of course, true beliefs based on guesses and hunches are not justified. However, Gettier cases have persuasively shown that even justified true beliefs can admit knowledge‐precluding kinds of luck. So in what sense are justified true beliefs that don’t amount knowledge lucky (...) or ‘true only by chance’? I will address three different approaches to epistemic luck that have received significant attention in the recent literature: reliability approaches to epistemic luck, credit approaches to epistemic luck, and responsibilist or control approaches to epistemic luck. I will then turn my attention to the implications that epistemic luck has for other epistemic states. I will focus particularly on state of understanding and examine whether, and to what extent, understanding is vulnerable to epistemic luck. (shrink)

In ‘The Semantics of Singular Terms’ (1976) Brian Loar proposed a famous case where a hearer seems to misunderstand an utterance even though he has correctly identified its referent. Loar’s case has been used to defend a model of communication where speaker and hearer must think of the referent in similar ways in order for communication to succeed. This ‘Similar Ways of Thinking’ (SW) theory is extremely popular, both in the literature on Loar cases and in other philosophical discussions. My (...) goal is to offer a novel argument against this influential model of communication and propose an alternative picture. First, I show how a certain version of SW fails to solve Loar’s puzzle. Then I point at a more general problem with SW, arguing that no version of this model can account for Loar-style cases without making the conditions for communication too strict. I then propose an alternative account of Loar cases, analyzing them as cases of luck where the hearer does not know that she has identified the referent correctly. I conclude by contrasting my view with other existing accounts of Loar cases. (shrink)

I challenge a cornerstone of the Gettier debate: that a proposed analysis of the concept of knowledge is inadequate unless it entails that people don’t know in Gettier cases. I do so from the perspective of Carnap’s methodology of explication. It turns out that the Gettier problem per se is not a fatal problem for any account of knowledge, thus understood. It all depends on how the account fares regarding other putative counter examples and the further Carnapian desiderata of exactness, (...) fruitfulness and simplicity. Carnap proposed his methodology more than a decade before Gettier’s seminal paper appeared, making the present solution to the problem a candidate for being the least ad hoc proposal on the market, one whose independent standing cannot be questioned, among solutions that depart from the usual method of revising a theory of knowledge in the light of counterexamples. As an illustration of the method at work, I reconstruct reliabilism as an attempt to provide an explication of the concept of knowledge. (shrink)

There is a clean image of knowledge transmission between thinkers that involves sincere and reliable speakers, and hearers who carefully assess the epistemic credentials of the testimony that they hear. There is, however, a murkier side to testimonial exchange where deception and lies hold sway. Such mendacity leads to sceptical worries and to discussion of epistemic vice. Here, though, I explore cases where deceit and lies are involved in knowledge transmission. This may sound surprising or even incoherent since lying usually (...) involves saying something that is false. Even if a liar unwittingly tells the truth, those believing their testimony would not acquire knowledge. In §1, however, I suggest a range of examples where lies can be used to transmit knowledge. The kinds of cases upon which I focus are those involving ‘engineered knowledge’, where a speaker skilfully manipulates another into having a true belief. Such cases are epistemologically significant for several reasons. First, they are counter-examples to a range of widely held assumptions about knowledge. We have, for example, cases where sincerity is not necessary for knowledge transmission, where there is knowledge from falsehood, and, as we shall discuss in §2, knowledge that is fragile or not safe. Second, in §3 and §4 I suggest that engineered knowledge is best captured by a virtue theoretic approach to testimonial transmission. (shrink)

In a recent paper “Safety, Sensitivity, and Differential Support” (Synthese, December 2017), Jose Zalabardo argues that (contra Sosa in Philos Perspect 33(13):141–153,1999) sensitivity can be differentially supported as the correct requirement for propositional knowledge. Zalabardo argues that safety fails to dominate sensitivity; specifically: some cases of knowledge failure can only be explained by sensitivity. In this paper, I resist Zalabardo’s conclusion that domination failure confers differential support for sensitivity. Specifically, I argue that counterexamples to sensitivity undermine differential support for sensitivity. (...) Using Zalabardo’s modal framework, I consider a less demanding modal condition, what I call weak sensitivity, and I explain how weak sensitivity avoids an influential counterexample to sensitivity. However, I argue that we can subvert that counterexample only by abandoning Zalabardo’s case for domination failure. So either way, we cannot differentially support sensitivity. (shrink)

We are witnessing a certain tendency in epistemology to account for the anti-luck intuition in terms of risk. I.e., instead of the traditional anti-luck diagnosis of Gettier cases and fake barn cases, a new anti-risk diagnosis seems to be preferable by many. My goal in this paper is twofold: first, I contribute to motivate that drift; and second, I defend that we ought to partially resist it. An anti-risk diagnosis is valid and preferable for fake barn cases, but we still (...) need an anti-luck diagnosis for classic Gettier cases. The paper thus defends the Solomon-like result that we need both concepts—epistemic luck and epistemic risk—to deal with all the cases where knowledge is undermined. (shrink)
