Knowledge ascriptions seem context sensitive. Yet it is widely thought that epistemic contextualism does not have a plausible semantic implementation. We aim to overcome this concern by articulating and defending an explicit contextualist semantics for ‘know,’ which integrates a fairly orthodox contextualist conception of knowledge as the elimination of the relevant alternatives, with a fairly orthodox “Amherst” semantics for A-quantification over a contextually variable domain of situations. Whatever problems epistemic contextualism might face, lack of an orthodox semantic implementation is not (...) among them. (shrink)

Recent theories of epistemic contextualism have challenged traditional invariantist positions in epistemology by claiming that the truth conditions of knowledge attributions fluctuate between conversational contexts. Contextualists often garner support for this view by appealing to folk intuitions regarding ordinary knowledge practices. Proposed is an experiment designed to test the descriptive conditions upon which these types of contextualist defenses rely. In the cases tested, the folk pattern of knowledge attribution runs contrary to what contextualism predicts. While preliminary, these data inspire prima (...) facie skepticism for the contextualist hypothesis regarding folk knowledge claims, as well as challenge certain predictions made by recent theories of subject-sensitive invariantism. It is further argued that such results raise methodological questions concerning the practice of relying on an assumption of intuitions, with respect to ordinary language practices, as evidence for philosophical conclusions regarding knowledge.

There is abundant evidence of contextual variation in the use of “S knows p.” Contextualist theories explain this variation in terms of semantic hypotheses that refer to standards of justification determined by “practical” features of either the subject’s context (Hawthorne & Stanley) or the ascriber’s context (Lewis, Cohen, & DeRose). There is extensive linguistic counterevidence to both forms. I maintain that the contextual variation of knowledge claims is better explained by common pragmatic factors. I show here that one is variable (...) strictness. “S knows p” is commonly used loosely to implicate “S is close enough to knowing p for contextually indicated purposes.” A pragmatic account may use a range of semantics, even contextualist. I use an invariant semantics on which knowledge requires complete justification. This combination meets the Moorean constraint as well as any linguistic theory should, and meets the intuition constraint much better than contextualism. There is no need for ad hoc error theories. The variation in conditions of assertability and practical rationality is better explained by variably strict constraints. It will follow that “S knows p” is used loosely to implicate that the condition for asserting “p” and using it in practical reasoning are satisfied. (shrink)

According to an influential Enlightenment ideal, one shouldn't rely epistemically on other people's say-so, at least not if one is in a position to evaluate the relevant evidence for oneself. However, in much recent work in social epistemology, we are urged to dispense with this ideal, which is seen as stemming from a misguided focus on isolated individuals to the exclusion of groups and communities. In this paper, I argue that that an emphasis on the social nature of inquiry should (...) not lead us to entirely abandon the Enlightenment ideal of epistemically autonomous agents. Specifically, I suggest that it is an appropriate ideal for those who serve as experts in a given epistemic community, and develop a notion of expert acceptance to make sense of this. I go on to show that, all other things being equal, this kind of epistemic autonomy among experts makes their joint testimony more reliable, which in turn brings epistemic benefits both to laypeople and to experts in other fields.

This essay is an accessible introduction to the proof paradox in legal epistemology. -/- In 1902 the Supreme Judicial Court of Maine filed an influential legal verdict. The judge claimed that in order to find a defendant culpable, the plaintiff “must adduce evidence other than a majority of chances”. The judge thereby claimed that bare statistical evidence does not suffice for legal proof. -/- In this essay I first motivate the claim that bare statistical evidence does not suffice for legal (...) proof. I then introduce and motivate a knowledge-centred explanation of this fact. The knowledge-centred explanation rests on two premises. The first is that legal proof requires knowledge of culpability. The second is that one cannot attain knowledge that p from bare statistical evidence that p. To motivate the second premise, I suggest that beliefs based on bare statistical evidence fail to be safe—they could easily be wrong—and bare statistical evidence cannot eliminate relevant alternatives. -/- I then cast doubt on the first premise; I argue that legal proof does not require knowledge. I thereby dispute the knowledge-centred explanation of the inadequacy of bare statistical evidence for legal proof. Instead of appealing to the nature of knowledge, I suggest we should seek a more direct explanation by appealing to those more foundational epistemic properties, such as safety or eliminating relevant alternatives.

ABSTRACT Contemporary relativists often see their view as contributing to a semantic/post-semantic account of linguistic data about disagreement and retraction. I offer an independently motivated metasemantic account of the same data, that also handles a number of cases and empirical results that are problematic for the relativist. The key idea is that the content of assertions and beliefs is determined in part by facts about other times, including times after the assertion is made or the belief is formed. On this (...) temporal externalist view, speaker behaviours such as retraction of previous assertions play a role in making it the case that a past utterance has a given meaning. (shrink)

It is widely assumed that memory has only the capacity to preserve epistemic features that have been generated by other sources. Specifically, if S knows (justifiedly believes/rationally believes) that p via memory at T2, then it is argued that (i) S must have known (justifiedly believed/rationally believed) that p when it was originally acquired at Tl, and (ii) S must have acquired knowledge that p (justification with respect to p/rationality with respect to p) at Tl via a non-memorial source. Thus, (...) according to this view, memory cannot make an unknown proposition known, an unjustified belief justified, or an irrational belief rational--it can only preserve what is already known, justified, or rational. In this paper, I argue that condition (i) is false and, a fortiori, that condition (ii) is false. Hence, I show that, contrary to received wisdom in contemporary epistemology, memory can function as a generative epistemic source. (shrink)

This paper considers some puzzling knowledge ascriptions and argues that they present prima facie counterexamples to credence, belief, and justification conditions on knowledge, as well as to many of the standard meta-semantic assumptions about the context-sensitivity of ‘know’. It argues that these ascriptions provide new evidence in favor of contextualist theories of knowledge—in particular those that take the interpretation of ‘know’ to be sensitive to the mechanisms of constraint.

G. E. Moore famously offered a strikingly straightforward response to the radical sceptic which simply consisted of the claim that one could know, on the basis of one's knowledge that one has hands, that there exists an external world. In general, the Moorean response to scepticism maintains that we can know the denials of sceptical hypotheses on the basis of our knowledge of everyday propositions. In the recent literature two proposals have been put forward to try to accommodate, to varying (...) extents, this Moorean thesis. On the one hand, there are those who endorse an externalist version of contextualism, such as Keith DeRose, who have claimed that there must be some contexts in which Moore is right. More radically still, Ernest Sosa has expanded on this externalist thesis by arguing that, contra DeRose's contextualism, Moore may be right in all contexts. In this paper I evaluate these claims and argue that, suitably modified, one can resurrect the main elements of the Moorean anti-sceptical thesis. (shrink)

Recently, some philosophers have defended the idea that knowledge is an interest-relative notion. According to this thesis, whether an agent knows P may depend on the practical costs of her being wrong about P. This perspective marks a radical departure from traditional accounts that take knowledge to be a purely intellectual concept. I think there is much to say on behalf of the interest-relative notion. In this paper, I report on some new evidence which strongly suggests that ordinary people’s attributions (...) of knowledge are in fact sensitive to practical interests. This is noteworthy because recent experiments have been interpreted by many to support the opposite conclusion. I also argue that the new results support an invariantist but interest-relativist account of knowledge, a thesis known as Interest Relative Invariantism (IRI). I do not make the case here that IRI gives us the very best explanation of the results presented here. Any such attempt would require an in-depth survey of the last few decades of work in epistemology. I only want to argue here that IRI gives us a simple and elegant explanation of the new data, and that the same cannot be said about traditional contextualism, a leading competitor to IRI. (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)

Epistemology today centrally concerns the conceptual analysis of knowledge. Historically, however, this is a concept that philosophers have seldom been interested in analysing, particularly when it is construed as broadly as the English language would have it. Instead, the overriding focus of epistemologists over the centuries has been, first, to describe the epistemic ideal that human beings might hope to achieve, and then go on to chart the various ways in which we ordinarily fall off from that ideal. I discuss (...) in detail two historical manifestations of idealized epistemology — Aristotle and Descartes — and then consider how this perspective might make a difference to the discipline today. In the end, an idealized epistemology points toward a normative, prescriptive rather than descriptive enterprise. (shrink)

According to Intellectualism knowing how to V is a matter of knowing a suitable proposition about a way of V-ing. In this paper, I consider the question of which ways of acting might figure in the propositions which Intellectualists claim constitute the object of knowledge-how. I argue that Intellectualists face a version of the Generality Problem – familiar from discussions of Reliabilism – since not all ways of V-ing are such that knowledge about them suffices for knowledge-how. I consider various (...) responses to this problem, and argue that none are satisfactory. (shrink)

Do you know who you are? If the question seems unclear, it might owe to the notion of ‘knowing-wh’ (knowing-who, knowing-what, knowing-when, etc.). Such knowledge contrasts with ‘knowing-that’, the more familiar topic of epistemologists. But these days, knowing-wh is receiving more attention than ever, and here we will survey three current debates on the nature of knowing-wh. These debates concern, respectively, (1) whether all knowing-wh is reducible to knowing-that (‘generalized intellectualism’), (2) whether all knowing-wh is relativized to a contrast proposition (...) (‘contrastivism about knowing-wh’), and (3) whether the context-sensitivity of knowing-wh is a semantic or purely pragmatic phenomenon (‘contextualism vs. invariantism about knowing-wh’). (shrink)

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

A plausible principle about the felicitous use of indicative conditionals says that there is something strange about asserting an indicative conditional when you know whether its antecedent is true. But in most contexts there is nothing strange at all about asserting indicative conditionals like ‘If Oswald didn’t shoot Kennedy, then someone else did’. This paper argues that the only compelling explanation of these facts requires the resources of contextualism about knowledge.

According to contextualist accounts, the truth value of a given knowledge ascription may vary with features of the ascriber's context. As a result, the following may be true: "X doesn't know that P but Y says something true in asserting 'X knows that P'". The contextualist must defend his theory in the light of this unpleasant but inevitable consequence. The best way of doing this is to construe the context sensitivity of knowledge ascriptions not as deriving from an alleged indexicality (...) of the word "know" nor from its vagueness or ambiguity, but rather from a distinct semantic feature of the word "know", namely its unspecificity. (shrink)

I am concerned with epistemic closure—the phenomenon in which some knowledge requires other knowledge. In particular, I defend a version of the closure principle in terms of analyticity; if an agent S knows that p is true and that q is an analytic part of p, then S knows that q. After targeting the relevant notion of analyticity, I argue that this principle accommodates intuitive cases and possesses the theoretical resources to avoid the preface paradox.

Deductive Cogency holds that the set of propositions towards which one has, or is prepared to have, a given type of propositional attitude should be consistent and closed under logical consequence. While there are many propositional attitudes that are not subject to this requirement, e.g. hoping and imagining, it is at least prima facie plausible that Deductive Cogency applies to the doxastic attitude involved in propositional knowledge, viz. belief. However, this thought is undermined by the well-known preface paradox, leading a (...) number of philosophers to conclude that Deductive Cogency has at best a very limited role to play in our epistemic lives. I argue here that Deductive Cogency is still an important epistemic requirement, albeit not as a requirement on belief. Instead, building on a distinction between belief and acceptance introduced by Jonathan Cohen and recent developments in the epistemology of understanding, I propose that Deductive Cogency applies to the attitude of treating propositions as given in the context of attempting to understand a given phenomenon. I then argue that this simultaneously accounts for the plausibility of the considerations in favor of Deductive Cogency and avoids the problematic consequences of the preface paradox. (shrink)

David Lewis (1941–2001) was one of the most important philosophers of the 20th Century. He made significant contributions to philosophy of language, philosophy of mathematics, philosophy of science, decision theory, epistemology, meta-ethics and aesthetics. In most of these fields he is essential reading; in many of them he is among the most important figures of recent decades. And this list leaves out his two most significant contributions. -/- In philosophy of mind, Lewis developed and defended at length a new version (...) of materialism (see the entry on physicalism). He started by showing how the motivations driving the identity theory of mind and functionalism could be reconciled in his theory of mind. He called this an identity theory, though his theory motivated the position now known as analytic functionalism. And he developed detailed accounts of mental content (building on Davidson’s interpretationism) and phenomenal knowledge (building on Nemirow’s ability hypothesis) that are consistent with his materialism. The synthesis Lewis ended up with is one of the central positions in contemporary debates in philosophy of mind. -/- But his largest contributions were in metaphysics. One branch of his metaphysics was his Hume-inspired reductionism about the nomological. He developed a position he called “Humean supervenience”, the theory that said that there was nothing to reality except the spatio-temporal distribution of local natural properties. And he did this by showing in detail how laws, chances, counterfactual dependence, causation, dispositions and colours could be located within this Humean mosaic. The other branch of his metaphysics was his modal realism. Lewis held that the best theory of modality posited concrete possible worlds. A proposition is possible if and only if it is true at one of these worlds. Lewis defended this view in his most significant book, On the Plurality of Worlds. Alongside this, Lewis developed a new account of how to think about modal properties of individuals, namely counterpart theory, and showed how this theory resolved several long-standing puzzles about modal properties.

Externalism about knowledge commits one to a modest form of contextualism: whether one knows depends (or may depend) on circumstances (context) of which one has no knowledge. Such modest contextualism requires the rejection of the KK Principle (If S knows that P, then S knows that S knows that P) - something most people would want to reject anyway - but it does not require (though it is compatible with) a rejection of closure. Radical contextualism, on the other hand, goes (...) a step farther and relativizes knowledge not just to the circumstances of the knower, but to the circumstances of the person attributing knowledge. I reject this more radical form of contextualism and suggest that it confuses (or that it can, at least, be avoided by carefully distinguishing) the relativity in what S is said to know from the relativity in whether S knows what S is said to know.

‘Know-that’, like so many natural language expressions, exhibits patterns of use that provide evidence for its context-sensitivity. A popular family of views – call it prag- matic invariantism – attempts to explain the shifty patterns by appeal to a pragmatic thesis: while the semantic meaning of ‘know-that’ is stable across all contexts of use, sentences of the form ‘S knows [doesn’t know] that p’ can be used to communicate a pragmatic content that depends on the context of use. In this (...) paper, the author argues that pragmatic invariantism makes inaccurate predictions for a wide range of well- known use data and is committed to attributing systematic pragmatic error to ordinary speakers. But pragmatic error is unprecedented, and it is doubtful that speakers are systematically wrong about what they intend to communicate. (shrink)

Since this paper is for a conference on “Contextualism in Epistemology and Beyond,” I have opted to sketch a retrospective of contextualism in epistemology, including highlights of the “relevant alternatives” approach, given how relevantism and contextualism have developed in tandem. We focus on externalist forms of contextualism, bypassing internalist forms such as Cohen 1988 and Lewis 1996, but much of our discussion will be applicable to contextualism generally. Internalist contextualism is helpfully discussed in papers by Stewart Cohen, Richard Feldman, and (...) Jonathan Vogel, in Tomberlin 1999. (shrink)

This paper surveys some ways in which epistemic reasons ascriptions (or ERAs) appear to be context-sensitive, and outlines a framework for thinking about the nature of this context-sensitivity that is intimately related to ERAs' explanatory function.

One of the central problems afflicting reductionism in the epistemology of testimony is the apparent fact that infants and small children are not cognitively capable of having the inductively based positive reasons required by this view. Since non-reductionism does not impose a requirement of this sort, it is thought to avoid this problem and is therefore taken to have a significant advantage over reductionism. In this paper, however, I argue that if this objection undermines reductionism, then a variant of it (...) similarly undermines non-reductionism. Thus, considerations about the cognitive capacities of infants and small children do not effectively discriminate between these two competing theories of testimonial justification. (shrink)

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

I am concerned with epistemic closure—the phenomenon in which some knowledge requires other knowledge. In particular, I defend a version of the closure principle in terms of analyticity; if an agent S knows that p is true, then S knows that all analytic parts of p are true as well. After targeting the relevant notion of analyticity, I argue that this principle accommodates intuitive cases and possesses the theoretical resources to avoid the preface paradox. I close by arguing that contextualists (...) who maintain that knowledge attributions are closed within—but not between—linguistic contexts are tacitly committed to this principle’s truth. (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.

David Lewis, Stewart Cohen, and Keith DeRose have proposed that sentences of the form S knows P are indexical, and therefore differ in truth value from one context to another.1 On their indexical contextualism, the truth value of S knows P is determined by whether S meets the epistemic standards of the speakers context. I will not be concerned with relational forms of contextualism, according to which the truth value of S knows P is determined by the standards of the (...) subject Ss context, regardless of the standards applying to the speaker making the knowledge claim. Relational contextualism is a form of normative relativism. Indexical contextualism is a semantic theory. When the subject is the speaker, as when S is the first person pronoun I, the two forms of contextualism coincide. But otherwise, they diverge. I critically examine the principal arguments for indexicalism, detail linguistic evidence against it, and suggest a pragmatic alternative. (shrink)

The use of ‘S knows p’ varies from context to context. The contextualist theories of Cohen, Lewis, and DeRose explain this variation in terms of semantic hypotheses: ‘S knows p’ is indexical in meaning, referring to features of the ascriber’s context like salience, interests, and stakes. The linguistic evidence against contextualism is extensive. I maintain that the contextual variation of knowledge claims results from pragmatic factors. One is variable strictness (Davis, Philos Stud, 132(3):395–438, 2007). In addition to its strict use, (...) ‘S knows p’ may be used loosely to implicate that S is close enough to knowing p for contextually indicated purposes. Here I explore another variable: belief about what is known. This factor is pragmatic rather than semantic in that it affects the use of ‘S knows p’ without affecting its truth conditions. While variation in strictness accounts for the variation in the bank, parking, and some lottery cases, variation in belief accounts for the variation in other lottery cases and the epistemology cases. Along the way, I sketch an insensitive invariantist semantics that is strict but non-skeptical, and show how it works with these pragmatic factors. (shrink)

Perhaps the most dominant anti‐sceptical proposal in recent literature –advanced by such figures as Stewart Cohen, Keith DeRose and David Lewis –is the contextualist response to radical scepticism. Central to the contextualist thesis is the claim that, unlike other non‐contextualist anti‐sceptical theories, contextualism offers a dissolution of the sceptical paradox that respects our common sense epistemological intuitions. Taking DeRose's view as representative of the contextualist position, it is argued that instead of offering us an intuitive response to scepticism, contextualism is (...) actually committed to a revisionist stance as regards our everyday usage of epistemic terms. In particular, it is argued that the thesis fails to present a satisfactory explication of a notion –that of‘epistemic descent’– that is pivotal to the anti‐sceptical import of the account. On the positive side, however, it is claimed that although the contextualist response to scepticism is ultimately unsatisfying, DeRose's theory does contain within it the framework for a completely different ‐ and far more persuasive ‐ account of the‘phenomenology’of scepticism which runs along non‐contextualist lines.

Reflection on the history of skepticism shows that philosophers have often conjoined as a single doctrine various theses that are best kept apart. Some of these theses are incredible – literally almost impossible to accept – whereas others seem quite plausible, and even verging on the platitudinous. Mixing them together, one arrives at a view – skepticism – that is as a whole indefensible. My aim is to pull these different elements apart, and to focus on one particular strand of (...) skepticism that deserves sustained and respectful attention. The strand I have in mind I will refer to as epistemic defeatism. Roughly, in its most global form, it is the view that, in the final analysis, we have no good evidence for the truth of any proposition. Working through various historical texts, I attempt to untangle epistemic defeatism from neighboring views, and in particular to establish its independence from questions about knowledge. Having thus established the view's autonomy, I turn to the options for self-consciously accepting defeat. One may despair or one may have faith. But I will ultimately propose that the most attractive option – the option that preserves the most of our epistemic integrity – is to have hope. (shrink)

I show that it follows from both externalist and internalist theories that stupid people may be in a better position to know than smart ones. This untoward consequence results from taking our epistemic goal to be accepting as many truths as possible and rejecting as many falsehoods as possible, combined with a recognition that the standard for acceptability cannot be set too high, else scepticism will prevail. After showing how causal, reliabilist, and coherentist theories devalue intelligence, I suggest that knowledge, (...) as contemporary theories construe it, is not a particularly valuable cognitive achievement, and that we would do well to reopen epistemology to the study of cognitive excellences of all sorts. (shrink)

Skeptical invariantism isn’t a popular view about the semantics of knowledge attributions. But what, exactly, is wrong with it? The basic problem is that it seems to run foul of the fact that we know quite a lot of things. I agree that it is a key desideratum for an account of knowledge that it accommodate the fact that we know a lot of things. But what sorts of things should a plausible theory of knowledge say that we know? In (...) this paper I sketch an answer to this question and then apply it to skeptical invariantism. I start by distinguishing between a “radical” skeptical invariantist position (on which the standards for knowing are so high that we rarely if ever satisfy them) and a more “moderate” skeptical invariantist position (on which the standards are very hard, but not impossible, to satisfy). I then argue that, while radical forms of skeptical invariantism are clearly not going to do a good job of satisfying the key desideratum, more moderate forms can do quite well with respect to it. In particular, I argue the version of moderate skeptical invariantism defended by Davide Fassio can plausibly satisfy it. (shrink)

A certain interpretation of Wittgenstein’s remarks in On Certaintyadvanced by such figures as Hilary Putnam, Peter Strawson, Avrum Stroll and Crispin Wrighthas become common currency in the recent literature. In particular, this reading focuses upon the supposed anti-sceptical import of the Wittgensteinian notion of a “hinge” proposition. In this paper it is argued that this interpretation is flawed both on the grounds that there is insufficient textual support for this reading and that, in any case, it leads to unpalatable philosophical (...) problems. Moreover, it is claimed that the popularity of this construal of On Certainty in the contemporary debate reflects an implicit commitment to the contentious doctrine of epistemological internalism. Nevertheless, it is argued that, suitably modified along the epistemologically externalist lines suggested by Michael Williams, one might be able to resurrect a viable anti-sceptical hinge proposition thesis. Furthermore, it is claimed that such a conception of the notion also receives some, albeit inconclusive, textual support from On Certainty. (shrink)

But it’s not the mere fact that the RA theorist needs an account of ‘ruling out’ and ‘relevance’ that has tended to lead people to regard the RA approach with suspicion. In itself, this simply means that the RA theorist has some further work to do; and what theorist doesn’t? No; the principal source of scepticism regarding the ability of the RA theorist to come up with a complete and satisfactory account of knowing stems, rather, from an unhappiness with the (...) specific elaborations of the core RA claim that various theorists have offered; for these elaborations have typically involved some rather controversial claims and/or assumptions, and it is against these claims/assumptions that the bulk of the criticism of the whole RA approach has been directed.

We may usefully distinguish between one’s having fallible knowledge and having a fallibilist stance on some of one’s knowledge. A fallibilist stance could include a concessive knowledge-attribution. But it might also include a questioning knowledge-attribution. Attending to the idea of a QKA leads to a distinction between what we may call closed knowledge that p and open knowledge that p. All of this moves us beyond Elgin’s classic tale of the epistemic capacities of Holmes and of Watson, and towards a (...) way of resolving Kripke’s puzzle about dogmatism and knowing. (shrink)

Positions in the debate about the correct semantics of “S knows that p” are sometimes motivated in part by an appeal to interpretive charity. In particular, non-skeptical views hold that many utterances of the sentence “S knows that p” are true and some of them think the fact that their views are able to respect this is a reason why their views are more charitable than skeptical invariantism. However, little attention has been paid to why charity should be understood in (...) this way and little effort has been spent justifying the notion that a charitable semantics is likely to be true. I distinguish two kinds of interpretive charity. One principle of charity is often appealed to in the literature. I introduce a second. I argue that while some positions better respect one principle of charity, the reverse is true of the other principle of charity. I conclude with some remarks about how to break this apparent tie.

The research project of common sense or folk behavior for the specific purposes of advancing epistemology has quickly become one of the largest in experimental philosophy. This chapter explains some of this work as it relates to two positions in epistemology: contextualism and interest relative invariantism (IRI). Naturally, questions arise about the relevance of folk behavior to debates in epistemology. First, there is the dialectical issue concerning the extent to which epistemologists have in fact relied on ordinary behavior in defending (...) their theories. Second, in the cases where epistemologists have made such appeals, people can ask if they have been correct in doing so. And third, assuming correctness in this regard, there is a question about which experimental methods, if any, are pertinent for understanding folk behavior. It is taken takes for granted that epistemologists appeal to ordinary usage and that their doing so in fact informs epistemology. (shrink)

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)

Contextualist theories of knowledge offer a semantic hypothesis to explain the observed contextual variation in what people say they know, and the difficulty people have resolving skeptical paradoxes. Subject or speaker relative versions make the truth conditions of “S knows that p” depend on the standards of either the knower’s context (Hawthorne and Stanley) or those of the speaker’s context (Cohen and DeRose). Speaker contextualism avoids objections to subject contextualism, but is implausible in light of evidence that “know” does not (...) behave like an indexical. I deepen and extend these criticisms in light of recent defenses by contextualists (including Ludlow). Another difficulty is that whether certain standards are salient or intended does not entail that they are the proper standards. A normative form of contextualism on which the truth of a knowledge claim depends on the proper standards for the context is more promising, but still unsatisfactory whether the view is speaker or subject relative. I defend alternative explanations for the observed linguistic and psychological data: a pragmatic account for some cases and a cognitive account for others. 1. (shrink)

Abstract MacFarlane distinguishes “context sensitivity” from “indexicality,” and argues that “nonindexical contextualism” has significant advantages over the standard indexical form. MacFarlane’s substantive thesis is that the extension of an expression may depend on an epistemic standard variable even though its content does not. Focusing on ‘knows,’ I will argue against the possibility of extension dependence without content dependence when factors such as meaning, time, and world are held constant, and show that MacFarlane’s nonindexical contextualism provides no advantages over indexical contextualism. (...) The discussion will shed light on the definition of indexicals as well as the meaning of ‘knows,’ and highlight important constraints on the way meaning can be represented in semantics.
