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)

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.

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. (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)

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)

I will discuss a variety of cases such that the subject's believing truly is somewhat of an accident, but less so than in a Gettier case. In each case, this is because her reasons are not ultimately undefeated full stop, but they are ultimately undefeated with certain qualifications. For example, the subject's reasons might be ultimately defeated considered in themselves but ultimately undefeated considered as a proper part of an inference to the best explanation that is undefeated without qualification. In (...) each section of the paper, I consider different qualifications and show how in each case we get an epistemic standing I call “coach-class knowledge”. First-class knowledge requires justifying reasons that are undefeated without qualification. Coach-class knowledge only requires qualified lack of defeat. I will use this distinction to bring debates over knowledge from falsehood and fake barns to an ecumenical resolution. In both cases, the subject enjoys coach-class rather than first-class knowledge. I will also show that the defeasible reasoning tradition can better account for graded accidental truth than safety theories. (shrink)

This paper provides an account of how virtue epistemology can accommodate knowledge acquired through testimony and extended cognition. Section 1 articulates the characteristic claim of virtue epistemology, and introduces the issues discussed in the paper. Section 2 details a related pair of objections to VE: that it is unable to accommodate cases of knowledge through testimony and extended cognition. Section 3 reviews two different virtue epistemologies and their responses to these objections presented in Greco :1–26, 2012). Considerations are presented for (...) why both of these accounts and responses are inadequate. Because of this, I suggest that it is unlikely that an analysis of the attribution relation will provide an adequate response to the objections. Section 4 advocates for a revised VE and a different way of dealing with the objections, which accommodates how agents are sometimes epistemically dependent on external sources. The central claim, for which a novel argument is presented, is that in some cases of knowledge the success is attributable to the abilities of an information system of which the knower is a part. This requires an important revision to traditional VE, but the characteristic claim of VE still holds true–every instance of knowledge is an instance of success attributable to ability. Thus, VE’s solutions to problems concerning the nature and value of knowledge are secured. (shrink)

I will argue for a novel variant of the knowledge norm for practical reasoning. In Sect. 2, I will look at current variations of a knowledge norm for practical reasoning and I will provide reasons to doubt these proposals. In Sects. 3 and 4, I develop my own proposal according to which knowledge is the norm of apt practical reasoning. Section 5 considers objections. Finally, Sect. 6 concerns the normativity of my proposed knowledge norm and its significance.

In this paper, I argue that, just as the problem of unconceived alternatives provides a basis for a New Induction on the History of Science to the effect that a realist view of science is unwarranted, the problem of unconceived objections provides a basis for a New Induction on the History of Philosophy to the effect that a realist view of philosophy is unwarranted. I raise this problem not only for skepticism’s sake but also for the sake of making a (...) point about philosophical argumentation, namely, that anticipating objections to one’s claim is not the same as supporting one’s claim. In other words, defending p from objections does not amount to support or evidence for p. This, in turn, presents dialectical and pragma-dialectical approaches to argumentation with the following question: does proper argumentation require that arguers anticipate and respond to unconceived objections? (shrink)

I argue against traditional virtue epistemology on which knowledge is a success due to a competence to believe truly, by revealing an in-principle problem with the traditional virtue epistemologist’s explanation of Gettier cases. The argument eliminates one of the last plausible explanation of Gettier cases, and so of knowledge, in terms of non-factive mental states and non-mental conditions. I then I develop and defend a different kind of virtue epistemology, on which knowledge is an exercise of a competence to know. (...) I show how the account, while circular, is not viciously so. It explains both how knowledge is a mental state, as well as the relationship between knowledge and justification, including justified false beliefs and Gettier cases. Moreover, although direct virtue epistemology is compatible with many views on the nature of belief, it can explain how knowledge might be metaphysically more fundamental than belief as well.

In recent years, philosophers have tended to think of luck as being a relation between an event and a subject; to give an account of luck is to fill in the right-hand side of the following biconditional: an event e is lucky for a subject S if and only if ____. We can call such accounts of luck subject-relative accounts of luck, since they attempt to spell out what it is for an event to be lucky relative to a subject. (...) This essay argues that we should understand subject-relative luck as a secondary phenomenon. What is of philosophical interest is giving an account of subject-involving luck, i.e., filling in the right-hand side of this biconditional: it is a matter of luck that S ϕs iff ____. The essay argues that one of the upshots of focusing on subject-involving luck is that lack of control accounts of luck become more attractive. In particular, a range of counterexamples to LCALs of subject-relative luck do not apply to LCALs of subject-involving luck. (shrink)

We can call any reductive account of knowledge that appeals to both safety and ability conditions a mixed account of knowledge. Examples of mixed accounts of knowledge include Pritchard’s (2012) Anti-Luck Virtue Epistemology, Kelp’s (2013) Safe-Apt account of knowledge, and Turri’s (2011) Ample belief account of knowledge. Mixed accounts of knowledge are motivated by well-known counterexamples to pure safety and pure ability accounts of knowledge. It is thought that by combining both safety and ability conditions we can give an extensionally (...) adequate reductive account of knowledge. In this paper I argue that the putative counterexamples to pure safety and pure ability accounts of knowledge fail to motivate mixed accounts of knowledge. In particular, I argue that if the putative counterexamples are problematic for safety accounts they are problematic for ability accounts and vice-versa. The reason for this, I argue, is that the safety condition and ability condition should be understood as alternative expressions of the same intuition — that knowledge must come from a reliable source. (shrink)

This essay takes up two questions. First, what does it mean to say that someone creates her own luck? At least colloquially speaking, luck is conceived as something out of an agent's control. So how could an agent increase or decrease the likelihood that she'll be lucky? Building on some recent work on the metaphysics of luck, the essay argues that there is a sense in which agents can create their own luck because people with more skill tend to have (...) more opportunities to benefit from luck. Second, what implications does this conception of luck have for related topics such as how we evaluate performances (like shooting an arrow), including coming to know something? The ubiquitous presence of luck in our actions is often underappreciated. The essay argues that when we combine an expected outcomes view of luck with a counterfactual view of causation, the distinction between environmental and intervening veritic luck seems to disappear. We need a more nuanced view of how luck sometimes undermines credit for success in agents' actions. The upshot of this view is that while luck may undermine the creditworthiness of an agent's success, it only partially undermines creditworthiness. (shrink)

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

Duncan Pritchard argues that a feature that sets understanding-why apart from knowledge-why is that whereas (I) understanding-why is a kind of cognitive achievement in a strong sense, (II) knowledge-why is not such a kind. I argue that (I) is false and that (II) is true. (I) is false because understanding-why featuring rudimentary explanations and understanding-why concerning very simple causal connections are not cognitive achievements in a strong sense. Knowledge-why is not a kind of cognitive achievement in a strong sense for (...) the same reason knowledge-that is not. The latter thesis requires showing that having (p because q) information is not equivalent to having information about facts or principles that establish the explanatory connections between the phenomena in question. I make a positive case for this claim and defend it against objections. Based on this argument, I identify an alternative feature that sets understanding-why apart from knowledge-why: The minimal condition for understanding-why and knowledge-why with respect to their contents is not identical. Knowing why p merely requires information that some explanatorily relevant dependency obtains. Understanding why p additionally requires information about facts or principles that establish the explanatory connections between the phenomena in question. (shrink)

Virtue epistemology (VE) suggests that S knows just in case S’s true belief is creditable to S’s competence. While Lackey’s ( 2007, 2009 ) objection from testimonial knowledge had raised concerns that VE is too strong, some virtue epistemologists (Sosa 2007, Pritchard 2012 ) adopted a weaker condition requiring only partial credit on agent’s part. This paper, however, argues that in addition to the creditable relation, the agent’s competence manifestation could be partial too—in the sense that only part of his/her (...) whole competence regarding the cognitive task is manifested. Interesting consequences follow as we explore this new way of dissecting cognitive agency—in particular, difficult cases for VE arise when one’s cognitive competence is partly apt and partly Gettiered. (shrink)

This paper purports to disprove an orthodox view in contemporary epistemology that I call ‘the epistemic conception of memory’, which sees remembering as a kind of epistemic success, in particular, a kind of knowing. This conception is embodied in a cluster of platitudes in epistemology, including ‘remembering entails knowing’, ‘remembering is a way of knowing’, and ‘remembering is sufficiently analogous to knowing’. I will argue that this epistemic conception of memory, as a whole, should be rejected insofar as we take (...) into account some putative necessary conditions for knowledge. It will be illustrated that while many maintain that knowing must be (1) anti-luck and (2) an achievement, the two conditions do not apply to remembering. I will provide cases where the subject successfully remembers that p but lacks knowledge that p for failing to meet the two putative conditions for knowledge. Therefore, remembering is not a kind of knowing but a sui generis cognitive activity. (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)

This article defends the view that knowledge is type-identical to cognitive achievement. I argue, pace Duncan Pritchard, that not only knowledge, but also cognitive achievement is incompatible with environmental luck. I show that the performance of cognitive abilities in environmental luck cases does not distinguish them from non-abilities per se. For this reason, although the cognitive abilities of the subject are exercised in environmental luck cases, they are not manifested in any relevant sense. I conclude by showing that this explanation (...) is not ad hoc as it can be generalized to apply to causal features besides cognitive abilities. (shrink)

According to philosophical orthodoxy, intuitions are perception‐like in that they provide us with non‐inferential justification. In this paper, I present four arguments to show that orthodoxy is mistaken: Intuitions, as used in thought experiments, are inferential judgments, that is the results of inferential transitions that are inferentially justified (if justified at all). The discussion will shed light on the nature of intuition but also on the nature of inference.

Virtue Reliabilism holds that knowledge is a cognitive achievement—an epistemic success that is creditable to the cognitive abilities of the knowing subject. Beyond this consensus, there is much disagreement amongst proponents of virtue reliabilism about the conditions under which the credit-relation between an epistemic success and a person’s cognitive abilities holds. This paper aims to establish a new and attractive view of this crucial relation in terms of difference-making. We will argue that the resulting theory, Difference-Making Virtue Epistemology, can deal (...) with cases of epistemic luck and testimonial knowledge while revealing the common core of knowledge and other achievements. (shrink)

I will present a problem for any externalist evidentialism that allows for accidental possession of evidence. There are Gettier cases for justification. I will describe two such cases – cases involving veridical hallucination. An analysis of the cases is given, along the lines of virtue epistemology . The cases show that certain externalist evidentialist accounts of justification do not provide sufficient conditions. The reason lies in the fact that one can be luckily in possession of evidence, and then one will (...) not have a justified belief. Justified belief requires an anti-luck condition on possession of evidence. This opens up the prospects of a unified virtue-epistemology covering both knowledge and justification. (shrink)

The notion of credit plays a central role in virtue epistemology and in the literature on moral worth. While virtue epistemologists and ethicists have devoted a significant amount of work to providing an account of creditable success, a unified theory of credit applicable to both epistemology and ethics, as well as a discussion of the general form it should take, are largely missing from the literature. Our goal is to lay out a theory of credit that seems to underlie much (...) of the discussion in virtue epistemology, which we dub the Cake Theory. We argue that given the goals that virtue epistemologists and ethicists who discuss moral worth have, this theory is problematic, for it makes credit depend on the wrong facts. (shrink)

In order to deal with the problem caused by environmental luck some proponents of robust virtue epistemology have attempted to argue that in virtue of satisfying the ability condition one will satisfy the safety condition. Call this idea the entailment thesis. In this paper it will be argued that the arguments that have been laid down for the entailment thesis entail a wrong kind of safety condition, one that we do not have in mind when we require our beliefs to (...) be safe from error in order for them to be knowledge. (shrink)

According to all varieties of virtue reliabilism knowledge is always gained through the exercise of epistemic competences. These competences can be conceived as competences to form true beliefs, or as competences to know. I will present a short but decisive argument against the idea that knowledge is always gained through the exercise of competences to know. The competence to know isn’t necessary for gaining knowledge.

Knowledge defeat occurs when a subject knows that _p_, gains a defeater for her belief, and thereby loses her knowledge without necessarily losing her belief. It’s far from obvious that externalists can accommodate putative cases of knowledge defeat since a belief that satisfies the externalist conditions for knowledge can satisfy those conditions even if the subject later gains a defeater for her belief. I’ll argue that virtue reliabilists can accommodate defeat intuitions via a new kind of error theory. I argue (...) that in cases where the subject holds dogmatically onto her belief in the face of an apparent defeater, her belief never qualified as knowledge, since the belief was not gained via an exercise of her epistemic virtues. In cases where the subject suspends her judgment upon receiving the putative defeater her original belief might have qualified as knowledge, but crucially, in such cases knowledge is lost due to loss of belief, rather than due to the epistemic force of the defeater. Therefore, knowledge defeat isn’t a genuine phenomenon even though there are no cases where a subject knows what she originally believed after receiving the putative defeater. (shrink)
