This paper presents corpus and experimental data that problematize the traditional analysis of must as a strong necessity modal, as recently revived and defended by von Fintel and Gillies :351–383, 2010). I provide naturalistic examples showing that must p can be used alongside an explicit denial of knowledge of p or certainty in p, and that it can be conjoined with an expression indicating that p is not certain or that not-p is possible. I also report the results of an (...) experiment involving lotteries, where most participants endorsed a sentence of the form must not-p despite being instructed that p is a possibility. Crucially, endorsement was much higher for must in this context than for matched sentences with knowledge or certainty expressions. These results indicate that the requirements for felicitous use of must are weaker than for know and certain rather than being at least as strong, as the epistemic necessity theory would predict. However, it is possible to account for these data while retaining the key insights of von Fintel and Gillies’ analysis of the evidential component of must. I discuss several existing accounts that could be construed in this way and explain why none is completely satisfactory. I then propose a new model that embeds an existing scalar theory into a probabilistic model of informational dynamics structured around questions and answers. (shrink)

Epistemic logic in the tradition of Hintikka provides, as one of its many applications, a toolkit for the precise analysis of certain epistemological problems. In recent years, dynamic epistemic logic has expanded this toolkit. Dynamic epistemic logic has been used in analyses of well-known epistemic “paradoxes”, such as the Paradox of the Surprise Examination and Fitch’s Paradox of Knowability, and related epistemic phenomena, such as what Hintikka called the “anti-performatory effect” of Moorean announcements. In this paper, we explore a variation (...) on basic dynamic epistemic logic—what we call sequential epistemic logic—and argue that it allows more faithful and fine-grained analyses of those epistemological topics.

A critique of attributer contextualist treatments of the problem of radical scepticism is offered. It is argued that while such proposals, standardly conceived, gain some purchase against the closure-based formulation of this problem, they run aground when applied to the logically distinct underdetermination-based formulation. A specific kind of attributer contextualism—rational support contextualism—is then explored. This is better placed to deal with underdetermination-based radical scepticism via its endorsement of ascriptions of factive rational support in everyday contexts of epistemic appraisal. But such (...) a proposal is faced with a dialectical impasse with regard to the competing epistemological disjunctivist response to radical scepticism. While the former has dialectical advantages over the latter with regard to closure-based radical scepticism, the latter has the dialectical upper-hand when it comes to underdetermination-based radical scepticism. It is claimed that the way to resolve this issue—and thereby to understand that we should not expect a unified treatment of these two formulations of the sceptical problem, much less one that is cast along contextualist lines—is to recognise how these two formulations reflect distinct sources of scepticism.

The philosophical case for extended cognition is often made with reference to ‘extended-memory cases’ ; though, unfortunately, proponents of the hypothesis of extended cognition as well as their adversaries have failed to appreciate the kinds of epistemological problems extended-memory cases pose for mainstream thinking in the epistemology of memory. It is time to give these problems a closer look. Our plan is as follows: in §1, we argue that an epistemological theory remains compatible with HEC only if its epistemic assessments (...) do not violate what we call ‘the epistemic parity principle’. In §2, we show how the constraint of respecting the epistemic parity principle stands in what appears to be a prima facie intractable tension with mainstream thinking about cases of propositional memory. We then outline and evaluate in §3 several lines of response. (shrink)

This paper criticizes phenomenal conservatism––the influential view according to which a subject S’s seeming that P provides S with defeasible justification for believing P. I argue that phenomenal conservatism, if true at all, has a significant limitation: seeming-based justification is elusive because S can easily lose it by just reflecting on her seemings and speculating about their causes––I call this the problem of reflective awareness. Because of this limitation, phenomenal conservatism doesn’t have all the epistemic merits attributed to it by (...) its advocates. If true, phenomenal conservatism would constitute a unified theory of epistemic justification capable of giving everyday epistemic practices a rationale, but it wouldn’t afford us the means of an effective response to the sceptic. Furthermore, phenomenal conservatism couldn’t form the general basis for foundationalism. (shrink)

We begin by asking what fallibilism about knowledge is, distinguishing several conceptions of fallibilism and giving reason to accept what we call strong epistemic fallibilism, the view that one can know that something is the case even if there remains an epistemic chance, for one, that it is not the case. The task of the paper, then, concerns how best to defend this sort of fallibilism from the objection that it is “mad,” that it licenses absurd claims such as “I (...) know that p but there’s a chance that not p ” and “ p but it there’s a chance that not p .” We argue that the best defense of fallibilism against this objection—a “pragmatist” defense—makes the following claims. First, while knowledge that p is compatible with an epistemic chance that not- p , it is compatible only with an insignificant such chance. Second, the insignificance of the chance that not- p is plausibly understood in terms of the irrelevance of that chance to p ’s serving as a ‘justifier’, for action as well as belief. In other words, if you know that p , then any chance for you that not p doesn’t stand in the way of p ’s being properly put to work as a basis for action and belief. (shrink)

A Moorean fact, in the words of the late David Lewis, is ‘one of those things that we know better than we know the premises of any philosophical argument to the contrary’. Lewis opens his seminal paper ‘Elusive Knowledge’ with the following declaration.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified (or absolutely warranted), i.e., justified to a degree that entails their truth and precludes their falsity. Though rationalist infallibilism is indisputably running its course, adherence to at least one of the two species of infallible a priori justification refuses to disappear from mainstream epistemology. Among others, Putnam (1978) still professes the a priori infallibility of some category (i) propositions, while Burge (...) (1986, 1988, 1996) and Lewis (1996) have recently affirmed the a priori infallibility of some category (ii) propositions. In this paper, I take aim at rationalist infallibilism by calling into question the a priori infallibility of both analytic and synthetic propositions. The upshot will be twofold: first, rationalist infallibilism unsurprisingly emerges as a defective epistemological doctrine, and second, more importantly, the case for the a priori infallibility of one or both categories of propositions turns out to lack cogency.

Mylan Engels paper (2004) is divided into two parts: a negative part, criticizing the costs of contextualism and a constructive part proposing a noncontextualist resolution of the skeptical problem. I will only address the constructive part here. The constructive part is composed of three elements: (i) a reconstruction or reformulation of the original skeptical argument, which draws on the notion of epistemic possibility (e-possibility), (ii) a distinction between two senses of knowledge (and two corresponding kinds of e-possibility): fallibilistic and infallibilistic, (...) and (iii) an argument which tries to hoist the skeptic by their own petard, namely the closure principle (CP). As I will argue, there are two ways to understand Engels anti-skeptical argument. Only in one interpretation does the argument depend on the proposed reconstruction of the skeptical argument in terms of e-possibility. But this version of the argument is unsound. More importantly, the skeptic has a strong prima facie objection at her disposal, which applies to both interpretations of the argument. If this objection is valid, Engels argument does not hold. But once it is invalidated, his argument is superfluous. (shrink)

The approach set forth by Edward Craig in Knowledge and the State of Nature has a greater explanatory value than it has been granted to date, and his suitably modified project can resolve a number of puzzling issues regarding the value of knowledge. The paper argues that a novel theory that relates knowledge to testimony is capable of explaining why knowledge is more valuable than mere true belief and why it has a distinctive value. Significantly, this theory avoids the recently (...) advanced revisionism regarding the focus of epistemological research. La aproximación de Edward Craig en Knowledge and the State of Nature tiene más poder explicativo del apreciado hasta ahora, y su proyecto, adecuadamente modificado, puede resolver un número de asuntos sobre el valor del conocimiento que parecen desconcertantes. Se argumenta que una novedosa teoría de conocimiento que lo relaciona con el testimonio puede explicar por qué el conocimiento es más valioso que la mera creencia verdadera, y por qué tiene un valor distintivo. Significativamente, la teoría evita un revisionismo, recientemente avanzado, con respecto al foco de la investigación epistemológica. (shrink)

What is the role of sceptical scenarios—dreams, evil demons, brains in a vat—in scep- tical arguments? According to the error view, sceptical scenarios illustrate the possibil- ity of massive falsity in one’s beliefs, whereas according to the ignorance view, they illustrate the possibility of massive ignorance not necessarily due to falsity. In this paper, the ignorance view is defended by surveying the arguments in favour of it and by replying to two pressing objections against it. According to the first objection, (...) the ignorance view illicitly introduces the kk-principle into sceptical arguments. In reply I argue that kk is not less plausible than its main rival, the closure principle. According to the second objection, relying on veridical ignorance-possibilities contradicts the transparency of belief. In reply I introduce a version of transparency that is consistent with the ignorance view. (shrink)

The prequel to this paper introduced the topic of iteration principles in epistemology and surveyed some arguments in support of them. In this sequel, I'll consider two influential families of objection to iteration principles. The first turns on the idea that they lead to some variety of skepticism, and the second turns on ‘margin for error’ considerations adduced by Timothy Williamson.

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.

This book explores a question central to philosophy--namely, what does it take for a belief to be justified or rational? According to a widespread view, whether one has justification for believing a proposition is determined by how probable that proposition is, given one's evidence. In this book this view is rejected and replaced with another: in order for one to have justification for believing a proposition, one's evidence must normically support it--roughly, one's evidence must make the falsity of that proposition (...) abnormal in the sense of calling for special, independent explanation. This conception of justification bears upon a range of topics in epistemology and beyond. Ultimately, this way of looking at justification guides us to a new, unfamiliar picture of how we should respond to our evidence and manage our own fallibility. This picture is developed here.

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.

In “Knowledge and epistemic necessity,” John Hawthorne gives a defense of what he rightly calls the “standard approach” to epistemic possibility against what he calls a new “competing idea” presented by Dougherty and Rysiew which he notes has been “endorsed and elaborated upon” by Fantl and McGrath. According to the standard approach, roughly, p is epistemically possible for S if S doesn’t know that not-p. The new approach has it that p is epistemically possible if p has a non-zero epistemic (...) probability. Both approaches, he notes, would explain the oddness of CKAs, utterances of the form “p, but possibly not p.” However, he offers a number of arguments designed to show that the standard approach has other advantages. In this paper, we undermine Hawthorne’s reasons for favoring the standard approach over Dougherty and Rysiew’s alternative approach. (shrink)

While recent discussions of contextualism have mostly focused on other issues, some influential early statements of the view emphasized the possibility of its providing an alternative to both coherentism and traditional versions of foundationalism. In this essay, I will pick up on this strand of contextualist thought, and argue that contextualist versions of foundationalism promise to solve some problems that their non-contextualist cousins cannot. In particular, I will argue that adopting contextualist versions of foundationalism can let us reconcile Bayesian accounts (...) of belief updating with a version of the holist claim that all beliefs are defeasible.

This paper defends a principle I call Equal Treatment, according to which the rationality of a belief is determined in precisely the same way as the rationality of any other state. For example, if wearing a raincoat is rational just in case doing so maximizes expected value, then believing some proposition P is rational just in case doing so maximizes expected value. This contrasts with the popular view that the rationality of belief is determined by evidential support. It also contrasts (...) with the common idea that in the case of belief, there are two different incommensurable senses of rationality, one of which is distinctively epistemic. I present considerations that favor Equal Treatment over these two alternatives, reply to objections, and criticize some arguments for Evidentialism. I also show how Equal Treatment opens the door to a distinctive kind of response to skepticism. (shrink)

This paper argues that there is a conflict between two theses held by John McDowell, namely i) the claim that we are under a standing obligation to revise our beliefs if reflection demands it; and ii) the view that veridical experience is a mode of direct access to the world. Since puts no bounds on what would constitute reasonable doubt, it invites skeptical concerns which overthrow. Conversely, since says that there are some experiences which we are entitled to trust, it (...) undermines the prescriptive scope of. Drawing on C. S. Peirce's distinction between genuine and contrived doubt, I maintain that critical revisions of beliefs should be triggered only by unwanted disruptions of habits, thereby restoring unity between McDowell's two theses.

Epistemic contrastivism is the view that knowledge is a ternary relation between a person, a proposition and a set of contrast propositions. This view is in tension with widely shared accounts of practical reasoning: be it the claim that knowledge of the premises is necessary for acceptable practical reasoning based on them or sufficient for the acceptability of the use of the premises in practical reasoning, or be it the claim that there is a looser connection between knowledge and practical (...) reasoning. Given plausible assumptions, epistemic contrastivism implies that we should cut all links between knowledge and practical reasoning. However, the denial of any such link requires additional and independent arguments; if such arguments are lacking, then all the worse for epistemic contrastivism. (shrink)

Epistemic contextualists like David Lewis allow that we have substantially infallibilist reflective intuitions about knowledge even though our everyday talk accepts fallibilist attributions of knowledge. They give serious weight to both our everyday talk and our propensity to assent to the skeptic's conclusions, and give us a concept of knowledge that accommodates both. The skeptic would, of course, leverage such infallibilist intuitions in order to undermine the legitimacy of our everyday attributions. Most contemporary epistemologists would simply argue that our concept (...) of knowledge is fallibilist, but this doesn't give them a particularly convincing reply to intuitively compelling skeptical arguments. ;This essay, most generally, takes up the question of how best to argue about skepticism. I claim that a philosophical account of knowledge that responds to skepticism should be able to clearly accommodate our epistemic agency. In chapter 1 I explain how skepticism challenges our naIve conception of agency and introduce two criteria for an adequate response to skepticism. In chapter 2, I discuss contextualist solutions; I argue they fail to satisfy our criteria and fail on their own terms; I explain how both failures relate to a failure to adequately treat epistemic agency. In chapter 3 I develop a conception of epistemic agency that describes what it is to be an active, reasoning source of belief. This picture is at odds with a dominant strain of epistemology that has it that one is substantially subject to belief, not effectively responsible for it; I criticize an influential argument by Bernard Williams that claims belief is not an attitude we control. This discussion in chapter 3 gives support to, a rationale for, the anti-insulationism requirement set out in chapter 1. Finally, in chapter 4 I return to the methodological issues of how to argue about skepticism. I first defend the idea that a knowledge-based skepticism is worth philosophical attention. I then offer an interpretation of what the skeptic is up to, and discuss what an effective counterstrategy might look like; I suggest that a particular sort of normative argument is the best way with the skeptic.

A sensible epistemologist may not see how she could know that she is not a brain in a vat ; but she doesn’t panic. She sticks with her empirical beliefs, and as that requires, believes that she is not a BIV. (She does not inferentially base her belief that she is not a BIV on her empirical knowledge—she rejects that ‘Moorean’ response to skepticism.) Drawing on the psychological literature on metacognition, I describe a mechanism that’s plausibly responsible for a sensible (...) epistemologist coming to believe she is not a BIV. I propose she thereby knows that she is not a BIV. The particular belief-forming mechanism employed explains why she overlooks this account of how she knows she is not a BIV, making it seem that there is no way for her to know it. I argue this proposal satisfactorily resolves the skeptical puzzle. (shrink)

Skeptical puzzles and arguments often employ knowledge-closure principles . Epistemologists widely believe that an adequate reply to the skeptic should explain why her reasoning is appealing albeit misleading; but it’s unclear what would explain the appeal of the skeptic’s closure principle, if not for its truth. In this paper, I aim to challenge the widespread commitment to knowledge-closure. But I proceed by first examining a new puzzle about failing to know—what I call the New Ignorance Puzzle . This puzzle resembles (...) to the Old Ignorance Puzzle , although it does not involve a closure principle. It instead centers on the standard view of ignorance, a highly intuitive principle stating that ignorance is merely a failure to know. In Sects. 2 and 3, I argue that the best way to solve the New Ignorance Puzzle is to reject the standard view of ignorance and to explain away its appeal via conversational implicature. I then use this solution to the New Ignorance Puzzle as a way of explaining why knowledge-closure principles would seem true, and why abominable conjunctions would seem abominable, even if such principles were false . The upshot is a new way of explaining why the skeptic’s reasoning is appealing albeit misleading. (shrink)

Epistemic contextualists think that the extension of the expression ‘knows’ depends on and varies with the context of utterance. In the last 15 years or so this view has faced intense criticism. This paper focuses on two sorts of objections. The first are what I call the ‘linguistic objections’, which purport to show that the best available linguistic evidence suggests that ‘knows’ is not context-sensitive. The second is what I call the ‘disagreement problem’, which concerns the behaviour of ‘knows’ in (...) disagreement reports. These may not be the only objections to epistemic contextualism, but they are probably the most influential. I argue that the best current epistemic contextualist response to the linguistic objection is incomplete, and I show how it can be supplemented to deal with the full range of linguistic objections. I also develop a new solution to the disagreement problem. The upshot is that neither sort of objection gives us any reason to reject epistemic contextualism. This conclusion is, in a sense, negative—no new arguments for epistemic contextualism are advanced—but it’s a vital step towards rehabilitating the view. (shrink)

In this paper I argue first, that a contrastive account of self-knowledge and the propositional attitudes entails an anti-individualist account of propositional attitude concepts, second, that the final account provides a solution to the McKinsey paradox, and third, that the account has the resources to explain why certain anti-skeptical arguments fail.

According to the principle of epistemic closure, knowledge is closed under known implication. The principle is intuitive but it is problematic in some cases. Suppose you know you have hands and you know that ‘I have hands’ implies ‘I am not a brain-in-a-vat’. Does it follow that you know you are not a brain-in-a-vat? It seems not; it should not be so easy to refute skepticism. In this and similar cases, we are confronted with a puzzle: epistemic closure is an (...) intuitive principle, but at times, it does not seem that we know by implication. In response to this puzzle, the literature has been mostly polarized between those who are willing to do away with epistemic closure and those who think we cannot live without it. But there is a third way. Here I formulate a restricted version of the principle of epistemic closure. In the standard version, the principle can range over any proposition; in the restricted version, it can only range over those propositions that are within the limits of a given epistemic inquiry and that do not constitute the underlying assumptions of the inquiry. If we adopt the restricted version, I argue, we can preserve the advantages associated with closure, while at the same time avoiding the puzzle I’ve described. My discussion also yields an insight into the nature of knowledge. I argue that knowledge is best understood as a topic-restricted notion, and that such a conception is a natural one given our limited cognitive resources. (shrink)

Nearly all success is due to some mix of ability and luck. But some successes we attribute to the agent’s ability, whereas others we attribute to luck. To better understand the criteria distinguishing credit from luck, we conducted a series of four studies on knowledge attributions. Knowledge is an achievement that involves reaching the truth. But many factors affecting the truth are beyond our control and reaching the truth is often partly due to luck. Which sorts of luck are compatible (...) with knowledge? We find that knowledge attributions are highly sensitive to lucky events that change the explanation for why a belief is true. By contrast, knowledge attributions are surprisingly insensitive to lucky events that threaten but ultimately fail to change the explanation for why a belief is true. These results shed light on our concept of knowledge, help explain apparent inconsistencies in prior work on knowledge attributions, and constitute progress toward a general understanding of the relation between success and luck.

This paper will articulate and defend a novel theory of epistemic justification; I characterize my view as the thesis that justification is potential knowledge . My project is an instance of the ‘knowledge-first’ programme, championed especially by Timothy Williamson. So I begin with a brief recapitulation of that programme.

In this paper, I will look at what role being able to provide justification plays in several prominent conceptions of epistemology, and argue that taking the ability to provide reasons as necessary for knowledge leads to a biasing toward false negatives. However, I will also argue that asking for reasons is a common practice among the general public, and one that is endorsed by “folk epistemology.” I will then discuss the fact that this asking for reasons is done neither constantly (...) nor arbitrarily, but rather in a systematic way that produces ignorance by oppressing some knowledge and some knowers, in particular those from already marginalized groups. After looking at the implications of all this, I will ultimately argue that we must be very careful when we ask for reasons, and acknowledge it as the powerful weapon it is. (shrink)

This article addresses and resolves an epistemological puzzle that has attracted much attention in the recent literature—namely, the puzzle arising from Moorean anti-sceptical reasoning and the phenomenon of transmission failure. The paper argues that an appealing account of Moorean reasoning can be given by distinguishing carefully between two subtly different ways of thinking about justification and evidence. Once the respective distinctions are in place we have a simple and straightforward way to model both the Wrightean position of transmission failure and (...) the Moorean position of dogmatism. The approach developed in this article is, accordingly, ecumenical in that it allows us to embrace two positions that are widely considered to be incompatible. The paper further argues that the Moorean Puzzle can be resolved by noting the relevant distinctions and our insensitivity towards them: once we carefully tease apart the different senses of ‘justified’ and ‘evidence’ involved, the bewilderment caused by Moore’s anti-sceptical strategy subsides.

There are sentences that express the same temporally fully specified proposition at all contexts--call them 'context-insensitive, temporally specific sentences.' Sentence (1) 'Obama was born in 1961' is a case in point: at all contexts, it expresses the proposition ascribing to the year 1961 the property of being a time in which Obama was born. Suppose that someone uttered (1) in a context located on Christmas 2000 in our world. In this context, (1) is a true sentence about the past. Moreover, (...) it seems impossible that (1) will be false in a successive context (one located, say, on Christmas 2020 in our world). More generally, one might be tempted to endorse the following principle: if a context-insensitive, temporally specific sentence is uttered in a context in which it is about the past and takes a certain truth value in this context, it cannot be the case that it takes a different truth value in a successive context located in the same world. In this paper, we present linguistic evidence that shows that this principle fails. On this basis, we draw an apparently crazy conclusion: the past can change. We then explain why this conclusion is not that crazy, after all. (shrink)

I investigate whether degreed beliefs are able to play the predictive, explanatory, and modeling roles that they are frequently taken to play. The investigation focuses on evidence—both from sources familiar in epistemology as well as recent work in behavioral economics and cognitive psychology—of variability in agents' apparent degrees of belief. Although such variability has been noticed before, there has been little philosophical discussion of its breadth or of the psychological mechanisms underlying it. Once these are appreciated, the inadequacy of degrees (...) of belief becomes clear. I offer a theoretical alternative to degrees of belief, what I call the filter theory. (shrink)

Radical skepticism is the view that we know nothing or at least next to nothing. Nearly no one actually believes that skepticism is true. Yet it has remained a serious topic of discussion for millennia and it looms large in popular culture. What explains its persistent and widespread appeal? How does the skeptic get us to doubt what we ordinarily take ourselves to know? I present evidence from two experiments that classic skeptical arguments gain potency from an interaction between two (...) factors. First, people evaluate inferential belief more harshly than perceptual belief. Second, people evaluate inferential belief more harshly when its content is negative (i.e., that something is not the case) than when it is positive (i.e., that something is the case). It just so happens that potent skeptical arguments tend to focus our attention on negative inferential beliefs, and we are especially prone to doubt that such beliefs count as knowledge. That is, our cognitive evaluations are biased against this specific combination of source and content. The skeptic sows seeds of doubt by exploiting this feature of our psychology. (shrink)

The notion of cognitive act is of importance for an epistemology that is apt for constructive type theory, and for epistemology in general. Instead of taking knowledge attributions as the primary use of the verb 'to know' that needs to be given an account of, and understanding a first-person knowledge claim as a special case of knowledge attribution, the account of knowledge that is given here understands first-person knowledge claims as the primary use of the verb 'to know'. This means (...) that a cognitive act is an act that counts as cognitive from a first-person point of view. The method of linguistic phenomenology is used to explain or elucidate our epistemic notions. One of the advantages of the theory is that an answer can be given to some of the problems in modern epistemology, such as the Gettier problem. (shrink)

Contextualism (the view that ‘knowledge’ and its variants are context-sensitive) has been supported in large part through appeal to intuitions about Keith DeRose’s Bank Cases. Recently, however, the contextualist construal of these cases has come under fire from Kent Bach and Jennifer Nagel who question whether the Bank Case subject’s confidence can remain constant in both low- and high-stakes cases. Having explained the Bank Cases and this challenge to them, I argue that DeRose has given a reasonable reply to this (...) initial challenge. However, I proceed to argue that the current stalemate can be broken. Seeking to extend the Bach-Nagel critique, I offer a novel interpretation of the Bank Cases according to which the subject’s evidence changes between low- and high-stakes cases. If I am correct, then, given the amount of support the Bank Cases have been thought to lend contextualism, the case for contextualism is seriously weakened. (shrink)

By “epistemic pragmatism” in general I will understand the claim that whether propositions instantiate certain key epistemic properties (such as being known or being justifiably believed) depends not just on factors traditionally recognized as epistemic, but also on pragmatic factors, such as how costly it would be to the subject if the proposition were false. In what follows I consider two varieties of epistemic pragmatism. According to what I shall call moderate epistemic pragmatism, how much evidence we need in favor (...) of a proposition in order to know that the proposition is true depends on our preferences. According to what I shall call extreme epistemic pragmatism, on the other hand, our preferences influence our epistemic position at a more basic level, because they help determine how much justification we actually have in favor of the proposition in question. Simplifying brutally, moderate epistemic pragmatism has it that the more worried we are about a proposition’s being false, the more justification we need in order to know it, whereas extreme epistemic pragmatism has it that the more worried we are about a proposition’s being false, the less justification we have for it. Recently, Fantl and McGrath have presented an interesting argument for moderate epistemic pragmatism, an argument which relies on the principle that (roughly) knowledge is sufficient for action (KA). In this paper I argue that KA, together with a plausible principle about second-order evidence, entails extreme epistemic pragmatism. (shrink)

Epistemic contextualists think that the truth-conditions of ‘knowledge’ ascriptions depend in part on the context in which they are uttered. But what features of context play a role in determining truth-conditions? The idea that the making salient of error possibilities is a central part of the story has often been attributed to contextualists, and a number of contextualists seem to endorse it (see Cohen (Philos Perspect, 13:57–89, 1999) and Hawthorne, (Knowledge and lotteries, Oxford University Press, Oxford, 2004)). In this paper (...) I argue that the focus on salience relations is a mistake. On the view I defend, the relevant features of context are facts about what error-possibilities and alternatives those in the context have a reason to consider, not facts about what error-possibilities and alternatives those in the context actually consider. As I will argue, this view has certain advantages over the standard view. (shrink)

In this article, against the background of a notion of ‘assembled’ truth, the evolutionary progressiveness of a theory is suggested as novel and promising explanation for the success of science. A new version of realism in science, referred to as ‘naturalised realism’ is outlined. Naturalised realism is ‘fallibilist’ in the unique sense that it captures and mimics the self-corrective core of scientific knowledge and its progress. It is argued that naturalised realism disarms Kyle Stanford’s anti-realist ‘new induction’ threats by showing (...) that ‘explanationism’ and his ‘epistemic instrumentalism’ are just two positions among many on a constantly evolving continuum of options between instrumentalism and full-blown realism. In particular it is demonstrated that not only can naturalised realism redefine the terms of realist debate in such a way that no talk of miracles need enter the debate, but it also promises interesting defenses against inductive- and under-determination-based anti-realist arguments.

It is widely acknowledged that epistemic modals admit of inter-subjective flexibility. This paper introduces intra-subjective flexibility for epistemic modals and draws on this flexibility to argue that fallibilism is consistent with the standard account of epistemic modals.

Magnetism in meta-semantics is the view that the meaning of our words is determined in part by their use and in part by the objective naturalness of candidate meanings. This hypothesis is commonly attributed to David Lewis, and has been put to philosophical work by Brian Weatherson, Ted Sider and others. I argue that there is no evidence that Lewis ever endorsed the view, and that his actual account of language reveals good reasons against it.

Traditionally it has been thought that the moral valence of a proposition is, strictly speaking, irrelevant to whether someone knows that the proposition is true, and thus irrelevant to the truth-value of a knowledge ascription. On this view, it’s no easier to know, for example, that a bad thing will happen than that a good thing will happen (other things being equal). But a series of very surprising recent experiments suggest that this is actually not how we view knowledge. On (...) the contrary, people are much more willing to ascribe knowledge of a bad outcome. This is known as the epistemic side-effect effect (ESEE), and is a specific instance of a widely documented phenomenon, the side-effect effect (a.k.a. “the Knobe effect”), which is the most famous finding in experimental philosophy. In this paper, I report a new series of five experiments on ESEE, and in the process accomplish three things. First, I confirm earlier findings on the effect. Second, I show that the effect is virtually unlimited. Third, I introduce a new technique for detecting the effect, which potentially enhances its theoretical significance. In particular, my findings make it more likely that the effect genuinely reflects the way we think about and ascribe knowledge, rather than being the result of a performance error. (shrink)

It is highly now intuitive that the future is open and the past is closed now—whereas it is unsettled whether there will be a fourth world war, it is settled that there was a first. Recently, it has become increasingly popular to claim that the intuitive openness of the future implies that contingent statements about the future, such as ‘There will be a sea battle tomorrow,’ are non-bivalent (neither true nor false). In this paper, we argue that the non-bivalence of (...) future contingents is at odds with our pre-theoretic intuitions about the openness of the future. These intuitions are revealed by our pragmatic judgments concerning the correctness and incorrectness of assertions of future contingents. We argue that the pragmatic data together with a plausible account of assertion shows that in many cases we take future contingents to be true (or to be false), though we take the future to be open in relevant respects. It follows that appeals to intuition to support the non-bivalence of future contingents are untenable. Intuition favours bivalence. (shrink)

On a common view of scenario-based sceptical arguments sceptical scenarios are error-possibilities, i.e. their point is to introduce the possibility of having only false beliefs. However, global error is impossible for purely logical/conceptual reasons: Even if one’s beliefs are consistent, the negations of one’s beliefs need not be consistent as well. My paper deals with the question of what the consequences of this result are. Two attempts at repairing scenario-based sceptical arguments within the framework of understanding sceptical scenarios as error-possibilities (...) are found wanting. Instead, what should be given up is the assumption that sceptical scenarios are error-possibilities. What is thought-provoking about the scenario of the brain in a vat is not that none of its empirical beliefs are true, but that all of its empirical beliefs fall short of knowledge at the same time. Hence, sceptical scenarios are not error-possibilities, but ignorance possibilities. If this is so, both the closure argument and the underdetermination argument commit a subtle mistake and should be replaced by slightly different arguments. The principle of excluded ignorance-possibilities turns out to be an epistemological principle that is faithful to scepticism’s tenets without misinterpreting sceptical scenarios as error-possibilities.

In his Knowledge and Practical Interests Jason Stanley argues that the view he defends, which he calls interest-relative invariantism, is better supported by certain cases than epistemic contextualism. In this article I argue that a version of epistemic contextualism that emphasizes the role played by the ascriber's practical interests in determining the truth-conditions of her ‘knowledge’ ascriptions – a view that I call interests contextualism – is better supported by Stanley's cases than interest-relative invariantism or other versions of epistemic contextualism. (...) My main aim is to show that interests contextualism is a viable, if often over-looked, alternative to the usual positions in the contemporary debate. (shrink)

A contribution to a symposium on Herman Cappelen's Philosophy without Intuitions.

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

For well over two decades, Andy Clark has been gleaning theoretical lessons from the leading edge of cognitive science, applying a combination of empirical savvy and philosophical instinct that few can match. Clark’s most recent book, Supersizing the Mind: Embodiment, Action, and Cognitive Extension, brilliantly expands his oeuvre. It offers a well-informed and focused survey of research in the burgeoning field of situated cognition, a field that emphasizes the contribution of environmental and non-neural bodily structures to the production of intelligent (...) behavior. The situated research program, fledgling though it may be in some respects, has reached an age at which its philosophical stock can reasonably be taken; and Clark is just the person to take it. Supersizing the Mind consists of three main divisions. The first develops the case for the distinctively extended view of cognition, according to which the human mind or cognitive system literally comprises elements beyond the boundary of the human organism. The second responds to critics of the extended outlook: Frederick Adams, Kenneth Aizawa, Keith Butler, Brie Gertler, Rick Grush, and me, among others. The third major division evaluates nonextended strands in the situated program, in particular, those that emphasize the role of the non-neural body in cognition. (shrink)

Research in experimental epistemology has revealed a great, yet unsolved mystery: why do ordinary evaluations of knowledge ascribing sentences involving stakes and error appear to diverge so systematically from the predictions professional epistemologists make about them? Two recent solutions to this mystery by Keith DeRose (2011) and N. Ángel Pinillos (2012) argue that these differences arise due to specific problems with the designs of past experimental studies. This paper presents two new experiments to directly test these responses. Results vindicate previous (...) findings by suggesting that (i) the solution to the mystery is not likely to be based on the empirical features these theorists identify, and (ii) that the salience of ascriber error continues to make the difference in folk ratings of third-person knowledge ascribing sentences.
