Here are two prima facie plausible theses about propositional knowledge: a belief could still constitute knowledge even if the belief is justified in a way that’s compatible with its being either false or accidentally true; each instance of knowledge is related to its subject in a way similar to that in which each intentional action is related to its agent. Baron Reed develops and defends a novel argument for the incompatibility of and. In this paper, I clarify and critically assess (...) Reed’s incompatibility argument. Against the backdrop of an example in which an action is non-intentional due to the role that an accidentally true belief plays in the action’s etiology, I argue that Reed’s incompatibility argument defeats itself: two of its premises are themselves jointly incompatible.

The Gettier dilemma facing reductive analyses of knowledge has not been properly appreciated by virtue epistemologist or even virtue epistemology’s most vocal critics. In §1, we start by considering how recent critics of virtue epistemology understand the Gettier Problem facing virtue-theoretic accounts of knowledge. I highlight how the dilemma facing virtue- theoretic analyses of knowledge is more general than these critics seem to suggest. In §2, I elucidate the worry that the threat facing virtue epistemology is really a dilemma between (...) Gettier counterexamples and radical skepticism. In §3, we will consider how some recent virtue epistemologists have tried to viably defuse the Gettier Problem. We will see (i) just how the critiques elucidated in §1 have (mis)shaped the dialectic between virtue epistemology and what is required in solving Gettier counterexamples and (ii) how this has led to virtue epistemologists underestimating the widespread insidiousness of Gettier counterexamples. (shrink)

If the history of the Gettier Problem has taught us anything, it is to be skeptical regarding purported solutions. Nevertheless, in “Manifest Failure: The Gettier Problem Solved” (2011), that is precisely what John Turri offers us. For nearly fifty years, epistemologists have been chasing a solution for the Gettier Problem but with little to no success. If Turri is right, if he has actually solved the Gettier Problem, then he has done something that is absolutely groundbreaking and really quite remarkable. (...) Regrettably, however, while Turri’s account is both intuitive and elegant—improving upon many seminal projects within contemporary epistemology—I argue in this paper that any success against Gettier counterexamples it affords is merely fleeting. Straightforwardly, this is done in two sections. In §1, I briefly sketch Turri’s proposed solution to the Gettier Problem. Then, in §2, I level a counterexample against it. Unfortunately for Turri and his solution, in this paper we will see history repeat itself. (shrink)

Does ‘remembering that p’ entail ‘knowing that p’? The widely-accepted epistemic theory of memory answers affirmatively. This paper purports to reveal the tension between ETM and the prevailing anti-luck epistemology. Central to my argument is the fact that we often ‘vaguely remember’ a fact, of which one plausible interpretation is that our true memory-based beliefs formed in this way could easily have been false. Drawing on prominent theories of misremembering in philosophy of psychology, I will construct cases where the subject (...) vaguely remembers that p while fails to meet the safety condition, which imply either that ETM is false or that safety is unnecessary for knowledge. The conclusion reached in this paper will be a conditional: if veritic epistemic luck is incompatible with knowledge, then ‘remembering that p’ does not entail ‘knowing that p’. (shrink)

According to robust virtue epistemology , knowledge is type-identical with a particular species of cognitive achievement. The identification itself is subject to some criticism on the grounds that it fails to account for the anti-luck features of knowledge. Although critics have largely focused on environmental luck, the fundamental philosophical problem facing RVE is that it is not clear why it should be a distinctive feature of cognitive abilities that they ordinarily produce beliefs in a way that is safe. We propose (...) a novel way to resolve this problem. Key to our proposal will be an appreciation of different representational states beholden to truth. We suggest these different representational states are distinguished by how, in the proper governance of these states, the twin goods of attaining truth and avoiding error are weighted. Moreover, we explain how varieties of representational states line up with varieties of cognitive achievement such that knowledge, cum cognitive achievement, must be safe because of the kind of attempt at success that belief is—namely, an attempt that places the premium it does on avoiding error. (shrink)

Our aim is to provide a topography of the relevant philosophical terrain with regard to the possible ways in which knowledge can be conceived of as extended. We begin by charting the different types of internalist and externalist proposals within epistemology, and we critically examine the different formulations of the epistemic internalism/externalism debate they lead to. Next, we turn to the internalism/externalism distinction within philosophy of mind and cognitive science. In light of the above dividing lines, we then examine first (...) the extent to which content externalism is compatible with epistemic externalism; second, whether active externalism entails epistemic externalism; and third whether there are varieties of epistemic externalism that are better suited to accommodate active externalism. Finally, we examine whether the combination of epistemic and cognitive externalism is necessary for epistemology and we comment on the potential ramifications of this move for social epistemology and philosophy of science.

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

A very natural view about perceptual knowledge is articulated, one on which perceptual knowledge is closely related to perceptual discrimination, and which fits well with a relevant alternatives account of knowledge. It is shown that this kind of proposal faces a problem, and various options for resolving this difficulty are explored. In light of this discussion, a two-tiered relevant alternatives account of perceptual knowledge is offered which avoids the closure problem. It is further shown how this proposal can: accommodate our (...) intuitions about perceptual knowledge and perceptual discrimination in terms of the notion of primary relevance, give an account of how alternatives can be rationally excluded without appeal to perceptual discrimination in terms of the notion of secondary relevance, and deal with the problem posed by inverted Gettier cases, and hence explain what it means to rationally exclude alternatives which are of secondary relevance.

A bi-level account of trust is developed and defended, one with relevance in ethics as well as epistemology. The proposed account of trust—on which trusting is modelled within a virtue-theoretic framework as a performance-type with an aim—distinguishes between two distinct levels of trust, apt and convictive, that take us beyond previous assessments of its nature, value, and relationship to risk assessment. While Ernest Sosa (2009; 2015; 2017), in particular, has shown how a performance normativity model may be fruitfully applied to (...) belief, my objective is to apply this kind of model in a novel and principled way to trust. I conclude by outlining some of the key advantages of the performance-theoretic bi-level account of trust defended over more traditional univocal proposals. (shrink)

The final chapter of Elgin’s defends the claim that some mistakes mark significant epistemic achievements. Here, I extend Elgin’s analysis of the informativeness of mistakes for epistemic policing. I also examine the type of theory of competence that Elgin’s view requires, and suggest some directions in which this can be taken.

Full aptness is the most important concept in performance-based virtue epistemology. The structure of full aptness, in epistemology and elsewhere, is bi-levelled. At the first level, we evaluate beliefs, like performances, on the basis of whether they are successful, competent, and apt – viz., successful because competent. But the fact that aptness itself can be fragile – as it is when an apt performance could easily have been inapt – points to a higher zone of quality beyond mere aptness. To (...) break in to this zone, one must not merely perform aptly but also in doing so safeguard in skilled ways against certain risks to inaptness. But how must this be done, exactly? This paper has two central aims. First, I challenge the credentials of mainstream thinking about full-aptness by raising some new and serious problems for the view. I then propose a novel account of full aptness – what I call de minimis normativism – which keeps all the advantages of the canonical view, avoids its problems entirely, and offers some additional payoffs.

Nearly all philosophers agree that only true things can be known. But does this principle reflect actual patterns of ordinary usage? Several examples in ordinary language seem to show that ‘know’ is literally used non-factively. By contrast, this paper reports five experiments utilizing explicit paraphrasing tasks, which suggest that non-factive uses are actually not literal. Instead, they are better explained by a phenomenon known as protagonist projection. It is argued that armchair philosophical orthodoxy regarding the truth requirement for knowledge withstands (...) current empirical scrutiny. (shrink)

A notorious objection to robust virtue epistemology—the view that an agent knows a proposition if and only if her cognitive success is because of her intellectual virtues—is that it fails to eliminate knowledge-undermining luck. Modest virtue epistemologists agree with robust virtue epistemologists that if someone knows, then her cognitive success must be because of her intellectual virtues, but they think that more is needed for knowledge. More specifically, they introduce independently motivated modal anti-luck principles in their accounts to amend the (...) problem of eliminating luck—this makes their views instances of impure virtue epistemology. The aim of the paper is to argue, firstly, that such a move lacks adequate motivation; secondly, that the resulting impure accounts equally fail to handle knowledge-undermining luck. On a more positive note, these results bolster a more orthodox virtue-theoretic approach to knowledge that assigns a fundamental explanatory role to the notion of ability. In this sense, the paper also sketches an account of ability and a corresponding account of knowledge that explains how success from ability is incompatible with success from luck. (shrink)

I argue that Duncan Pritchard’s anti-luck virtue epistemology is insufficient for knowledge. I show that Pritchard fails to achieve the aim that motivates his adoption of a virtue-theoretic condition in the first place: to guarantee the appropriate direction of fit that known beliefs have. Finally, I examine whether other virtue-theoretic accounts are able to explain what I call the direction of fit problem.

What is the nature of knowledge? A popular answer to that long-standing question comes from robust virtue epistemology, whose key idea is that knowing is just a matter of succeeding cognitively—i.e., coming to believe a proposition truly—due to an exercise of cognitive ability. Versions of robust virtue epistemology further developing and systematizing this idea offer different accounts of the relation that must hold between an agent’s cognitive success and the exercise of her cognitive abilities as well as of the very (...) nature of those abilities. This paper aims to give a new robust virtue epistemological account of knowledge based on a different understanding of the nature and structure of the kind of abilities that give rise to knowledge. (shrink)

Virtue Epistemology appealingly characterizes knowledge as a kind of achievement, attributable to the exercise of cognitive virtues. But a more thorough understanding of the nature and value of achievements more broadly casts doubt on the view. In particular, it is argued that virtue epistemology’s answer to the Meno question is not as impressive as it purports to be, and that the favored analysis of ability is both problematic and irrelevant. However, considerations about achievements illuminate the best direction for the development (...) of virtue epistemology. The key, it is argued, is developing the notion of manifestation as the distinguishing feature of both knowledge and achievements. (shrink)

Achievement is among the central goods in life, but just what is achievement, and how is it valuable? There is reason to think that it is a constitutive part of wellbeing; yet, it is possible to sacrifice wellbeing for the sake of achievement. How might it have been worthwhile, if not in terms of wellbeing? Perhaps, achievement is an intrinsic good, or perhaps it is valuable in terms of meaning in life. This article considers various ways in which we can (...) understand the nature and value of achievement, as well as the significance of achievement for other areas of philosophical inquiry.

The paper makes two points. First, any theory of knowledge must explain the difference between cases of knowledge from falsehood and Gettier cases where the subject relies on reasoning from falsehood. Second, the closeness-to-the-truth approach to explaining the difference between knowledge-yielding and knowledge-suppressing falsehoods does not hold up to scrutiny.

We report experimental results showing that participants are more likely to attribute knowledge in familiar Gettier cases when the would-be knowers are performing actions that are negative in some way (e.g. harmful, blameworthy, norm-violating) than when they are performing positive or neutral actions. Our experiments bring together important elements from the Gettier case literature in epistemology and the Knobe effect literature in experimental philosophy and reveal new insights into folk patterns of knowledge attribution.

This essay defends a novel form of virtue epistemology: Modal Virtue Epistemology. It borrows from traditional virtue epistemology the idea that knowledge is a type of skillful performance. But it goes on to understand skillfulness in purely modal terms — that is, in terms of success across a range of counterfactual scenarios. We argue that this approach offers a promising way of synthesizing virtue epistemology with a modal account of knowledge, according to which knowledge is safe belief. In particular, we (...) argue that the modal elements of the view offer important advantages over traditional virtue epistemology, which assigns a central explanatory role to aptness. At the same time, the virtue epistemological elements of the theory reveal new avenues for overcoming obstacles to traditional modal accounts of knowledge. Finally, we highlight the advantages of Modal Virtue Epistemology over alternative syntheses, such as Pritchard's (2012) hybrid approach. (shrink)

I argue against the Standard View of ignorance, according to which ignorance is defined as equivalent to lack of knowledge, that cases of environmental epistemic luck, though entailing lack of knowledge, do not necessarily entail ignorance. In support of my argument, I contend that in cases of environmental luck an agent retains what I call epistemic access to the relevant fact by successfully exercising her epistemic agency and that ignorance and non-ignorance, contrary to what the Standard View predicts, are not (...) modal in the sense that knowledge is. After responding to objections, I conclude by sketching an alternative account of ignorance centered on the notions of epistemic access and epistemic agency. (shrink)

Information and Communication Technologies, ICTs, has now for decades being increasingly taken into use for higher education, enabling distance learning, e-learning and online learning, mainly in parallel to mainstream educational practise. The concept Blended learning (BL) aims at the integration of ICTs with these existing educational practices. The term is frequently used, but there is no agreed-upon definition. The general aim of this dissertation is to identify new possible perspectives on ICTs and access to higher education, for negotiating the dichotomy (...) between campus-based and ICT-enabled education. The access options of BL are in focus for this dissertation, although BL is generally seen as a campus phenomenon, and shares a place perspective. The main research questions in the dissertation are 1) how BL can be understood in the context of increased access to education, moreover, (2) how time can be work as a more constructive perspective for designing ICTs in education, compared to place. The dissertation comprises five articles. The first is conceptual and concentrates on place and time in blended learning, and forms a time-based model and perspective, drawing on the tension between synchronous and asynchronous modalities instead of a place-based center-periphery model. The following article examines the differences between North American and European use of the term BL, in education and research, and finds that BL is not much used by European researchers, although the term is frequently used in educational environments. Two design and intervention studies, articles 3 and 4, make experiments using the BL time-based model. In article 3, a group of untraditional learners at a learning centre in Arvidsjaur attends a synchronous co-located study circle group and participates in an asynchronous and global Massive Open Online Course (MOOC). In article 4, nine students in a preparatory year for entering engineering studies volunteer and participate in a pilot distance course experiment, where prevention of procrastination is a high priority. For this, agile framework theory, constructivist learning theory and the time-based model are used in design and analysis. The last article (5) reconnects learning to place by discussing and adapting Triple- and Quadruple Helix theory for regional development in the knowledge society to four regional European cases. At the end of the synthesis, an outline of the access affordances with the time-based model is given, drawing on Adam’s timescape theory. The discussion of ICT integration into education is made drawing on Floridi’s Philosophy of Information, which provides many tools to view discourses of ICTs in education critically, and also envisions the concept of e-ducation in the infosphere, where other blend issues appear connected to weak artificial intelligence and the pervasive power of ICTs.

I argue that you can have a priori knowledge of propositions that neither are nor appear necessarily true. You can know a priori contingent propositions that you recognize as such. This overturns a standard view in contemporary epistemology and the traditional view of the a priori, which restrict a priori knowledge to necessary truths, or at least to truths that appear necessary.

Deviant causal chain problems arise in many settings. The most famous instance of the problem is the Gettier problem, but the problem also arises in the philosophy of action and perception. Usually, attempts to tackle these problems try to solve them individually. This paper takes a different approach: I propose a general solution to the problem. I begin by providing a solution to the deviant causal chain problem for skillful performance, and I argue that the solution can be extended to (...) solve the Gettier problem and the deviant causal chain problems for perception and intentional action. As I develop my solution to these problems, I also compare it with other solutions to bring out the advantages of my approach. I then explain why the solution generalizes: my solution provides us with an analysis of disposition manifestation, which is the key to ruling out deviance. I conclude by considering objections and giving my replies. (shrink)

The term “Gettier Case” is a technical term frequently applied to a wide array of thought experiments in contemporary epistemology. What do these cases have in common? It is said that they all involve a justified true belief which, intuitively, is not knowledge, due to a form of luck called “Gettiering.” While this very broad characterization suffices for some purposes, it masks radical diversity. We argue that the extent of this diversity merits abandoning the notion of a “Gettier case” in (...) a favour of more finely grained terminology. We propose such terminology, and use it to effectively sort the myriad Gettier cases from the theoretical literature in a way that charts deep fault lines in ordinary judgments about knowledge. (shrink)

According to the safety principle, if one knows that p, then one’s belief in p could not easily have been false. In this paper, I pose a dilemma for safety theorists by asking the following question: In evaluating whether or not a belief is safe, must we only examine the error-possibilities of the same belief as formed in the actual world? If ‘yes’, safety meets a familiar objection regarding necessary truths and the objection also extends to contingent propositions. If ‘no’, (...) however, there is no necessity of safety for knowledge. It is argued that this dilemma poses a threat for a number of safety principles from the recent literature. In the end, I draw implications of my arguments for the debate between robust and anti-luck virtue epistemologies. The result is that anti-luck virtue epistemology suffers from the difficulty with the safety principle whereas the robust variant remains intact. (shrink)

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)

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)

ABSTRACTAchievements are among the things that make a life good. Assessing the plausibility of this intuitive claim requires an account of the nature of achievements. One necessary condition for achievement appears to be that the achieving agent acted competently, i.e. was not just lucky. I begin by critically assessing existing accounts of anti-luck conditions for achievements in both the ethics and epistemology literature. My own proposal is that a goal is reached competently, only if the actions of the would-be-achiever make (...) success likely, and that this is the reason why she acts that way. (shrink)

Elsewhere, I have challenged virtue epistemology and argued that it doesn’t square with mundane cases of extended cognition. Kelp (forthcoming, this journal) and Greco (forthcoming) have responded to my charges, the former by questioning the force of my argument, the latter by developing a new virtue epistemology. Here I consider both responses. I show first that Kelp mischaracterizes my challenge. Subsequently, I identify two new problems for Greco’s new virtue epistemology.

I report two experiments studying the relationship among explicit judgments about what people see, know, and should assert. When an object of interest was surrounded by visibly similar items, it diminished people’s willingness to judge that an agent sees, knows, and should tell others that it is present. This supports the claim, made by many philosophers, that inhabiting a misleading environment intuitively decreases our willingness to attribute perception and knowledge. However, contrary to stronger claims made by some philosophers, inhabiting a (...) misleading environment does not lead to the opposite pattern whereby people deny perception and knowledge. Causal modeling suggests a specific psychological model of how explicit judgments about perception, knowledge, and assertability are made: knowledge attributions cause perception attributions, which in turn cause assertability attributions. These findings advance understanding of how these three important judgments are made, provide new evidence that knowledge is the norm of assertion, and highlight some important subtleties in folk epistemology. (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)

I accomplish two things in this paper. First I expose some important limitations of the contemporary literature on the norms of assertion and in the process illuminate a host of new directions and forms that an account of assertional norms might take. Second I leverage those insights to suggest a new account of the relationship between knowledge and assertion, which arguably outperforms the standard knowledge account.

Philosophers have debated whether it is possible to knowledgeably infer a conclusion from a false premise. For example, if a fan believes that the actress’s dress is blue, but the dress is actually green, can the fan knowledgeably infer “the dress is not red” from “the dress is blue”? One aspect of this debate concerns what the intuitively correct verdict is about specific cases such as this. Here I report a simple behavioral experiment that helps answer this question. The main (...) finding is that people attribute knowledge in cases where a true conclusion is inferred from a false premise. People did this despite judging that the premise was false and unknown. People also viewed the agent as inferring the conclusion from the premise. In closely matched conditions where the conclusion was false, people did not attribute knowledge of the conclusion. These results support the view that the ordinary knowledge concept includes in its extension cases of knowledge inferred from false premises. (shrink)

In a single-iteration fake barn case, the agent correctly identifies an object of interest on the first try, despite the presence of nearby lookalikes that could have mislead her. In a multiple-iteration fake barn case, the agent first encounters several fakes, misidentifies each of them, and then encounters and correctly identifies a genuine item of interest. Prior work has established that people tend to attribute knowledge in single-iteration fake barn cases, but multiple-iteration cases have not been tested. However, some theorists (...) contend that multiple-iteration cases are more important and will elicit a strong tendency to deny knowledge. Here I report a behavioural experiment investigating knowledge judgments in multiple-iteration fake barn cases. The main finding is that people tend to attribute knowledge in these cases too. Ironically, the results indicate that the presence of fakes could prevent iterated errors from lowering knowledge attributions. The results also provide evidence that ordinary knowledge attributions are based on attributions of cognitive ability. (shrink)

According to Veritism, true belief is the sole fundamental epistemic value. Epistemologists often take Veritism to entail that all other epistemic items can only have value by standing in certain instrumental relations—namely, by tending to produce a high ratio of true to false beliefs or by being products of sources with this tendency. Yet many value theorists outside epistemology deny that all derivative value is grounded in instrumental relations to fundamental value. Veritists, I believe, can and should follow suit. After (...) setting the stage in §1, I explain in §2 why Veritism should not take an Instrumentalist form. Instrumentalist Veritism faces a generalized version of the swamping problem. But this problem undermines Instrumentalism, not Veritism: granting Instrumentalism, similar problems arise for any economical epistemic axiology. I show in §3 how Veritism can take a less narrow form and solve the swamping problem. After answering some objections in §4, I consider in §5 what some would regard as a less radical alternative solution and argue that it either fails or collapses into mine. I close in §6 by taking stock and re-evaluating the overall prospects for Veritism, suggesting that it is a highly promising epistemic axiology when divorced from Instrumentalism. (shrink)

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)

[Significantly updated in Chapter 6 of Awareness and the Substructure of Knowledge] In order for a reason to justify an action or attitude it must be one that is possessed by an agent. Knowledge-centric views of possession ground our possession of reasons, at least partially, either in our knowledge of them or in our being in a position to know them. On virtually all accounts, knowing P is some kind of non-accidental true belief that P. This entails that knowing P (...) is a kind of non-accidental true representation that P. I outline a novel theory of the epistemic requirement on possession in terms of this more general state of non-accidental true representation. It is just as well placed to explain the motivations behind knowledge-centric views of possession, and it is also better placed to explain the extent of the reasons we possess in certain cases of deductive belief-updates and cases involving environmental luck. I conclude with three reflections. First, I indicate how my arguments generate a dilemma for Errol Lord’s view that possessing reasons is just a matter of being in a position to manifest one’s knowledge how to use them. Second, I explain how my view can simultaneously manage cases of environmental luck without falling prey to lottery cases. Finally, I sketch the direction for a further range of counterexamples to knowledge-centric theories of possession. (shrink)

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)

We propose a Bayesian framework for the attribution of knowledge, and apply this framework to generate novel predictions about knowledge attribution for different types of “Gettier cases”, in which an agent is led to a justified true belief yet has made erroneous assumptions. We tested these predictions using a paradigm based on semantic integration. We coded the frequencies with which participants falsely recalled the word “thought” as “knew” (or a near synonym), yielding an implicit measure of conceptual activation. Our experiments (...) confirmed the predictions of our Bayesian account of knowledge attribution across three experiments. We found that Gettier cases due to counterfeit objects were not treated as knowledge (Experiment 1), but those due to intentionally-replaced evidence were (Experiment 2). Our findings are not well explained by an alternative account focused only on luck, because accidentally-replaced evidence activated the knowledge concept more strongly than did similar false belief cases (Experiment 3). We observed a consistent pattern of results across a number of different vignettes that varied the quality and type of evidence available to agents, the relative stakes involved, and surface details of content. Accordingly, the present findings establish basic phenomena surrounding people’s knowledge attributions in Gettier cases, and provide explanations of these phenomena within a Bayesian framework.

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)

In this paper we argue that knowledge is characteristically safe true belief. We argue that an adequate approach to epistemic luck must not be indexed to methods of belief formation, but rather to explanations for belief. This shift is problematic for several prominent approaches to the theory of knowledge, including virtue reliabilism and proper functionalism (as normally conceived). The view that knowledge is characteristically safe true belief is better able to accommodate the shift in question.

In this paper, I will present a problem for reductive accounts of knowledge-undermining epistemic luck. By “reductive” I mean accounts that try to analyze epistemic luck in non-epistemic terms. I will begin by briefly considering Jennifer Lackey's (2006) criticism of Duncan Pritchard's (2005) safety-based account of epistemic luck. I will further develop her objection to Pritchard by drawing on the defeasible-reasoning tradition. I will then show that her objection to safety-based accounts is an instance of a more general problem with (...) reductive accounts of epistemic luck. In short, they face a dilemma: they can either fail to vindicate the intuitive verdicts about cases or they can illicitly appeal to the epistemic vocabulary they are trying to reduce. The upshot is that we can only understand epistemic luck in terms of the assessment of the subject's reasons and we can't give a reductive account of that. (shrink)
