Epistemic contextualism is one of the most hotly debated topics in contemporary epistemology. Contextualists claim that ‘know’ is a context-sensitive verb associated with different evidential standards in different contexts. Contextualists motivate their view based on a set of behavioural claims. In this paper, I show that several of these behavioural claims are false. I also show that contextualist test cases suffer from a critical confound, which derives from people's tendency to defer to speakers’ statements about their own mental (...) states. My evidence consists in results from several behavioural experiments. I conclude that contextualism is an idle hypothesis and I propose some general methodological lessons. (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 chapter, I produce counterexamples to Presuppositional Epistemic Contextualism (PEC), a view about the semantics of ‘knowledge’-ascriptions that I have argued for elsewhere. According to PEC, the semantic content of the predicate ‘know’ at a context C is partly determined by the speakers’ pragmatic presuppositions at C. The problem for the view that I shall be concerned with here arises from the fact that pragmatic presuppositions are sometimes known to be true by the speakers who make them: (...) hence the Problem of Known Presuppositions. After discussing several unsuccessful ways to solve the problem, I propose the addition of a new Lewisian rule of proper ignoring to the semantics of PEC--namely, the Rule of Evidence-Based Ignoring. If the proposed account succeeds, the Problem of Known Presuppositions has a straightforward solution within the framework of PEC. (shrink)

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)

It has been argued that epistemic contextualism faces the so-called factivity problem and hence cannot be stated properly. The basic idea behind this charge is that contextualists supposedly have to say, on the one hand, that knowledge ascribing sentences like “S knows that S has hands” are true when used in ordinary contexts while, on the other hand, they are not true by the standard of their own context. In my paper, I want to show that the argument (...) to the factivity problem fails because it rests on the mistaken premise that contextualists are committed to the truth of particular ordinary knowledge attributions.

Introduces contextualism about knowledge ascriptions, and provides a brief summary of the contributions to the Routledge Handbook of Epistemic Contextualism.

Epistemic Contextualism is the view that “knows that” is semantically context-sensitive and that properly accommodating this fact into our philosophical theory promises to solve various puzzles concerning knowledge. Yet Epistemic Contextualism faces a big—some would say fatal—problem: The Semantic Error Problem. In its prominent form, this runs thus: speakers just don’t seem to recognise that “knows that” is context-sensitive; so, if “knows that” really is context-sensitive then such speakers are systematically in error about what is said (...) by, or how to evaluate, ordinary uses of “S knows that p”; but since it's wildly implausible that ordinary speakers should exhibit such systematic error, the expression “knows that” isn't context-sensitive. We are interested in whether, and in what ways, there is such semantic error; if there is such error, how it arises and is made manifest; and, again, if there is such error to what extent it is a problem for Epistemic Contextualism. The upshot is that some forms of The Semantic Error Problem turn out to be largely unproblematic. Those that remain troublesome have analogue error problems for various competitor conceptions of knowledge. So, if error is any sort of problem, then there is a problem for every extant competitor view. (shrink)

There are two issues I want to very briefly raise in response to Robin McKenna’s paper, “Epistemic Contextualism, Epistemic Relativism, and Disagreement.” First, I want to question whether or not the disagreement problem faced by indexical contextualism is truly a problem. Secondly, I want to consider whether or not McKenna’s solution is really in keeping with indexical contextualism.

This chapter has four central aims. First, in §1, I distinguish two ideas within epistemology that sometimes travel under the name ‘contextualism’ — the ‘situational contextualist’ idea that an individual’s context, especially their social context, can make for a difference in what they know, and the ‘linguistic contextualist’ idea that discourse using the word ‘knows’ and its cognates is context-sensitive, expressing dif- ferent contents in different conversational contexts. -/- Second, in §2, I situate contextualism with respect to several (...) influential ideas in feminist epistemology. These ideas are thoroughgoingly contextualist in the situational sense; I’ll explore the prospects for linguistic contextualist analogues or implementations of them. Simple connections between these feminist ideas and linguistic contextualism will prove elusive, but more subtle ones are possible, and sometimes attractive. -/- §3 considers the degree to which contextual epistemic parameters are determined interpersonally, as opposed to individualistically. Should contextualists hold that speakers can individually determine the contextual parameters that influence the truth- conditions of their utterances? Or are they fixed at a broader social level? I’ll rehearse some influential reasons to opt for the latter, more social, form of contextualism. -/- In §4 I discuss the practical and moral significance of speakers’ choices of epistemic parameters, given contextualism. For example, I’ll consider how standards-raising can be used to discredit evidential sources, with an eye towards the social and moral consequences of such moves. (shrink)

In the recent philosophy of language literature there is a debate over whether contextualist accounts of the semantics of various terms can accommodate intuitions of disagreement in certain cases involving those terms. Relativists such as John MacFarlane have claimed that this motivates adopting a form of relativist semantics for these terms because the relativist can account for the same data as contextualists but doesn’t face this problem of disagreement (MacFarlane 2005, 2007 and 2009). In this paper I focus on the (...) case of epistemic predicates and I argue that on a certain assumption about what is involved in assessing an utterance the epistemic contextualist can solve her problem of disagreement. This undercuts a motivation for epistemic relativism. (shrink)

Epistemic invariantism, or invariantism for short, is the position that the proposition expressed by knowledge sentences does not vary with the epistemic standard of the context in which these sentences can be used. At least one of the major challenges for invariantism is to explain our intuitions about scenarios such as the so-called bank cases. These cases elicit intuitions to the effect that the truth-value of knowledge sentences varies with the epistemic standard of the context in which (...) these sentences can be used. In this paper, I will defend invariantism against this challenge by advocating the following, somewhat deflationary account of the bank case intuitions: Readers of the bank cases assign different truth-values to the knowledge claims in the bank cases because they interpret these scenarios such that the epistemic position of the subject in question differs between the high and the low standards case. To substantiate this account, I will argue, first, that the bank cases are underspecified even with respect to features that should uncontroversially be relevant for the epistemic position of the subject in question. Second, I will argue that readers of the bank cases will fill in these features differently in the low and the high standards case. In particular, I will argue that there is a variety of reasons to think that the fact that an error-possibility is mentioned in the high standards case will lead readers to assume that this error-possibility is supposed to be likely in the high standards case. (shrink)

In this essay I show how to reconcile epistemic invariantism with the knowledge account of assertion. My basic proposal is that we can comfortably combine invariantism with the knowledge account of assertion by endorsing contextualism about speech acts. My demonstration takes place against the backdrop of recent contextualist attempts to usurp the knowledge account of assertion, most notably Keith DeRose's influential argument that the knowledge account of assertion spells doom for invariantism and enables contextualism's ascendancy.

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.

On Kratzer’s canonical account, modal expressions (like “might” and “must”) are represented semantically as quantifiers over possibilities. Such expressions are themselves neutral; they make a single contribution to determining the propositions expressed across a wide range of uses. What modulates the modality of the proposition expressed—as bouletic, epistemic, deontic, etc.—is context.2 This ain’t the canon for nothing. Its power lies in its ability to figure in a simple and highly unified explanation of a fairly wide range of language use. (...) Recently, though, the canon’s neat story has come under attack. The challenge cases involve the epistemic use of a modal sentence for which no single resolution of the contextual parameter appears capable of accommodating all our intuitions.3 According to these revisionaries, such cases show that the canonical story needs to be amended in some way that makes multiple bodies of information relevant to the assessment of such statements. Here I show that how the right canonical, flexibly contextualist account of modals can accommodate the full range of challenge cases. The key will be to extend Kratzer’s formal semantic account with an account of how context selects values for a modal’s.. (shrink)

The paper discusses approaches to Epistemic Contextualism that model the satisfaction of the predicate ‘know’ in a given context C in terms of the notion of belief/fact-matching throughout a contextually specified similarity sphere of worlds that is centred on actuality. The paper offers three counterexamples to approaches of this type and argues that they lead to insurmountable difficulties. I conclude that what contextualists (and Subject-Sensitive Invariantists) have traditionally called the ‘epistemic standards’ of a given context C cannot (...) be explicated in terms of a contextually specified similarity sphere that is centred on actuality. The mentioned accounts of epistemic relevance and thus the corresponding accounts of the context-sensitivity (or subject-sensitivity) of ‘knows’ are to be rejected. (shrink)

Epistemic contextualism is widely believed to be incompatible with the recently popular view that knowledge is the norm of assertion, practical reasoning, or belief. I argue in this article that the problems arising for contextualism from the mentioned normative views are only apparent and can be resolved by acknowledging the fairly widespread phenomenon of non-obvious context-sensitivity (recently embraced by even some of contextualism's most ardent former critics). Building on recent insights about non-obvious context-sensitivity, the article outlines (...) an independently attractive contextualist account of the mentioned epistemic norms and provides a solution to the puzzles they give rise to in a contextualist framework. (shrink)

My paper aims to account for the possibility of disagreements concerning what we know; for clearly, people disagree about what they know. More precisely, my goal is to explain how a contextualist theory of knowledge attributions can explain the existence of disagreement among speakers. My working hypothesis is that genuine epistemic disagreement is possible only under the assumption that the meaning of the word “knowledge” is governed by contexts that are objective, in the sense that the content of the (...) word “knowledge” is fixed for all speakers sharing a common conversational goal. The paper is divided into two sections. In the first section, I explain why current versions of epistemic contextualism cannot account for epistemic disagreement. In the second section, following Christopher Gauker’s theory of linguistic communication, I offer my own contextualist solution to the problem of epistemic disagreement. (shrink)

Epistemic contextualism (EC) is primarily a semantic view, viz. the view that ‘knowledge’-ascriptions can change their contents with the conversational context. To be more precise, EC is the view that the predicate ‘know’ has an unstable Kaplan character, i.e. a character that does not map all contexts on the same content. According to EC, ‘know’ is thus an indexical expression. Notwithstanding this purely linguistic characterisation of EC, contextualists have traditionally argued that their views have considerable philosophical impact, this (...) being due to the alleged fact that their linguistic views about ‘know’ provide the resources for a resolution of sceptical puzzles. In this paper I will address an objection to EC claiming that, as a linguistic view about the term ‘know’, EC cannot be of any epistemological significance. (shrink)

In this entry, we provide an overview of some of the methodological debates surrounding contextualism and consider whether they are, in effect, based on an underlying methodological dispute. We consider three modes of motivation of epistemic contextualism including i) the method of cases, ii) the appeal to linguistic analogies and iii) the appeal to conceptual analogies and functional roles. We also consider the methodological debates about contextualism arising from experimental philosophy. We conclude that i) there is (...) no distinctive methodological doctrine or set of methodological doctrines that is centrally invoked by all epistemic contextualists and ii) the substantive dispute about the truth of contextualism very frequently, although not invariably, reflects an underlying methodological dispute. (shrink)

I provide an opinionated overview of the literature on the relationship of contextualism to knowledge norms for action, assertion, and belief. I point out that contextualists about ‘knows’ are precluded from accepting the simplest versions of knowledge norms; they must, if they are to accept knowledge norms at all, accept “relativized” versions of them. I survey arguments from knowledge norms both for and against contextualism, tentatively concluding that commitment to knowledge norms does not conclusively win the day either (...) for contextualism or for its rivals. But I also suggest that an antecedent commitment to contextualism about normative terms may provide grounds for suspicion about knowledge norms, and a debunking explanation of some of the data offered in favor of such norms. (shrink)

Contextualism in epistemology has traditionally been understood as the view that “know” functions semantically like an indexical term, encoding different contents in contexts with different epistemic standards. But the indexical hypothesis about “know” faces a range of objections. This article explores an alternative version of contextualism on which “know” is a semantically stable term, and the truth-conditional variability in knowledge claims is a matter of pragmatic enrichment. The central idea is that in contexts with stringent epistemic (...) standards, knowledge claims are narrowed: “know” is used in such contexts to make assertions about particularly demanding types of knowledge. The resulting picture captures all of the intuitive data that motivate contextualism while sidestepping the controversial linguistic thesis at its heart. After developing the view, the article shows in detail how it avoids one influential linguistic objection to traditional contextualism concerning indirect speech reports, and then answers an objection concerning the unavailability of certain types of clarification speeches. (shrink)

Jason Stanley has argued recently that Epistemic Contextualism and Subject‐Sensitive Invariantism are explanatorily on a par with regard to certain data arising from modal and temporal embeddings of ‘knowledge’‐ascriptions. This paper argues against Stanley that EC has a clear advantage over SSI in the discussed field and introduces a new type of linguistic datum strongly suggesting the falsity of SSI.

According to some powerful skeptical arguments, we know almost nothing. Contextualist theories of knowledge ascriptions have been developed with an eye toward resisting skepticism. Have the contextualists succeeded? After briefly outlining their view, I will consider whether contextualism about knowledge ascriptions provides a satisfactory response to one of the most popular and influential forms of skepticism. I conclude with some questions for the contextualist. As we’ll see, the effectiveness of the contextualist solution to skepticism is far from settled.

In this paper I develop a version of contextualism that I call interests contextualism. Interests contextualism is the view that the truth-conditions of knowledge ascribing and denying sentences are partly determined by the ascriber’s interests and purposes. It therefore stands in opposition to the usual view on which the truth-conditions are partly determined by the ascriber’s conversational context. I give an argument against one particular implementation of the usual view, differentiate interests contextualism from other prominent versions (...) of contextualism and argue that, unlike those versions, interests contextualism can mitigate against the epistemic descent objection put forward by Duncan Pritchard in his ‘Contextualism, Scepticism, and the Problem of Epistemic Descent’ (the objection is that, on the contextualist view, an ascriber of knowledge cannot, for some subject S and proposition p, properly ascribe knowledge that p to S if that ascriber has previously retracted an earlier ascription of knowledge that p to S). (shrink)

Recently, contextualism about epistemic modals and predicates of taste have come under fire from advocates of assessment relativistic analyses. Contextualism, they have argued, fails to account for what we call "felicitous insensitive assessments". In this paper, we provide one hitherto overlooked way in which contextualists can embrace the phenomenon by slightly modifying an assumption that has remained in the background in most of the debate over contextualism and relativism. Finally, we briefly argue that the resulting contextualist (...) account is at least as plausible as the relativist alternative and should be carefully considered before contextualism is abandoned for relativism. (shrink)

In the past few years there has been a turn towards evaluating the empirical foundation of epistemic contextualism using formal (rather than armchair) experimental methods. By-and-large, the results of these experiments have not supported the original motivation for epistemic contextualism. That is partly because experiments have only uncovered effects of changing context on knowledge ascriptions in limited experimental circumstances (when contrast is present, for example), and partly because existing experiments have not been designed to distinguish between (...) contextualism and one of its main competing theories, subject-sensitive invariantism. In this paper, we discuss how a particular, "third-person", experimental design is needed to provide evidence that would support contextualism over subject-sensitive invariantism. In spite of the theoretical significance of third-person knowledge ascriptions for debates surrounding contextualism, no formal experiments evaluating such ascriptions that assess contextualist claims have previously been conducted. In this paper, we conduct an experiment specifically designed to examine that central gap in contextualism’s empirical foundation. The results of our experiment provide crucial support for epistemic contextualism over subject-sensitive invariantism. (shrink)

A very simple contextualist treatment of a sentence containing an epistemic modal, e.g. a might be F, is that it is true iff for all the contextually salient community knows, a is F. It is widely agreed that the simple theory will not work in some cases, but the counterexamples produced so far seem amenable to a more complicated contextualist theory. We argue, however, that no contextualist theory can capture the evaluations speakers naturally make of sentences containing epistemic (...) modals. If we want to respect these evaluations, our best option is a relativist theory of epistemic modals. On a relativist theory, an utterance of a might be F can be true relative to one context of evaluation and false relative to another. We argue that such a theory does better than any rival approach at capturing all the behaviour of epistemic modals. (shrink)

There are various ways in which context matters in ethics. Most clearly, the context in which an action is performed might determine whether the action is morally right: though it is often wrong not to keep a promise, it might be permissible in certain contexts. More radically, proponents of moral particularism (see particularism) have argued that a reason for an action in one context is not guaranteed to be a reason in a different context: whether it is a reason against (...) an act that it breaks a promise or inflicts pain might depend on the particulars of the situation. In moral epistemology, Timmons (1999: Ch. 5) argues that whether a moral judgment is epistemically responsible depends both on the basic moral outlook of the moral judge and on whether the context of judgment is one of engaged moral thinking, or one of distanced, skeptical reflection. In the former, the judge’s basic moral outlook can serve to justify the judgment; not so in the latter (see epistemology, moral). -/- Our focus here, however, will be on forms of metaethical, and more precisely semantic, contextualism in moral discourse and moral thinking. According to these forms of contextualism (henceforth “metaethical contextualism,” or just “contextualism”), the meaning or truth-conditions of a moral judgment depend not only on the properties of the act it concerns, but also on features of the context in which the judgment is made, such as the standards endorsed by the moral judge or the parties of the conversation. If metaethical contextualism is correct, it might be that when two persons judge that abortions must be banned, one person’s judgment might be true whereas the other person’s is false, because they accept different fundamental norms. This would undermine the idea that there are objectively correct answers to moral questions. -/- Metaethical contextualism is supported from three directions. First, what is expressed by terms such as “good” and “ought” seems to be context-dependent when used outside ethics, being dependent on a variety of interests and concerns. One might therefore expect similar context dependence when these terms are used to express moral judgments, assuming a corresponding variety of interests and concerns in moral contexts. Second, many have thought that deep moral disagree- ments suggest that the interests and concerns behind moral judgments do vary in this way. Finally, contextualism promises to make sense of what seems to be an intrinsic yet defeasible connection between moral judgments and moral motivation, by tying the meaning or truth-conditions of moral judgments closely to interests and concerns of moral judges. At the same time, contextualism faces two broad kinds of problems: to make sense of the seemingly categorical or objective preten- sions of moral claims, and to explain why the parties to deep moral disagreement often behave as if they were disagreeing about substantive issues rather than talking past each other. In the sections that follow, we look closer at both sources of support and problems for contextualism. (shrink)

The paper takes as its starting point the observation that people can be led to retract knowledge claims when presented with previously ignored error possibilities, but offers a noncontextualist explanation of the data. Fallibilist epistemologies are committed to the existence of two kinds of Kp -falsifying contingencies: (i) Non-Ignorable contingencies [NI-contingencies] and (ii) Properly-Ignorable contingencies [PI-contingencies]. For S to know that p, S must be in an epistemic position to rule out all NI-contingencies, but she need not be able (...) to rule out the PI-contingencies. What is required vis-à-vis PI-contingencies is that they all be false . In mentioning PI-contingencies, an interlocutor can lead S mistakenly to think that these contingencies are NI-contingencies, when in fact they are not. Since S cannot rule out these newly mentioned contingencies and since she mistakenly takes them to be NI-contingencies , it is quite natural that she retract her earlier knowledge claim. In short, mentioning NI-contingencies creates a distortion effect. It makes S think that the standards for knowledge are higher than they actually are, which in turn explains why she mistakenly thinks she lacks knowledge. Conclusion: The primary linguistic data offered in support of contextualism can be explained without resorting to contextualism. (shrink)

Abstract In this paper I argue that to understand the ethics of belief we need to put it in a context of what we care about. Epistemic values always arise from something we care about and they arise only from something we care about. It is caring that gives rise to the demand to be epistemically conscientious. The reason morality puts epistemic demands on us is that we care about morality. But there may be a (small) class of (...) beliefs which it is not wrong to hold unconscientiously. I also argue that epistemic values enjoy a privileged place in the panorama of what we care about because they are entailed by anything we care about. That means that when there is a conflict between caring about knowledge or true belief and caring about something else, that conflict cannot be resolved simply by following the one we care about the most because caring about knowledge in any domain is entailed by caring about that domain. Finally, I argue that whereas caring demands different degrees of conscientiousness in different contexts, contextualism about knowledge is less plausible. (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)

Contextualism in epistemology is the claim that the knowledge predicate is contextsensitive in the sense that it has different truth conditions across different contexts of use. Jason Stanley objects against this view that if it were correct! then "know" should be gradable in the same way as gradable adjectives. Since it lacks gradability it also lacks the postulated contextsensitivity. Or so Stanley argues. In this paper I show that the contextualist is not committed to the gradability of the knowledge (...) predicate in the first place. I will distinguish between what I will call pure threshold predicates, which either apply simpliciter or not at all in each context, and impure threshold predicates, for which context determines whether they apply simpliciter, but which can also be satisfied to certain degrees. Threshold predicates are not gradable, but many of exhibit just the kind of contextsensitivity that is postulated for "know". Pace Stanley, three claims are going to be established: that the lack of gradability of the knowledge predicate (i) does not jeopardize its contextsensitivity, (ii) does not dismantle the analogies contextualists have claimed to hold between "know" and gradable adjectives, and (iii) is perfectly consistent with the idea of varyingly high epistemic standards.

The paper is concerned with the semantics of knowledge attributions(K-claims, for short) and proposes a position holding that K-claims are contextsensitive that differs from extant views on the market. First I lay down the data a semantic theory for K-claims needs to explain. Next I present and assess three views purporting to give the semantics for K-claims: contextualism, subject-sensitive invariantism and relativism. All three views are found wanting with respect to their accounting for the data. I then propose a (...) hybrid view according to which the relevant epistemic standards for evaluating K-claims are neither those at the context of the subject (subject-sensitive invariantism), nor those at the context of the assessor (relativism), but it is itself an open matter. However, given that we need a principled way of deciding which epistemic standards are the relevant ones, I provide a principle according to which the relevant standards are those that are the highest between those at the context of the subject and those at the context of the assessor/attributor. In the end I consider some objections to the view and offer some answers. (shrink)

This is an encyclopedia article about epistemic closure principles. The article explains what they are, their various philosophical uses, how they are argued for or against, and provides an overview of the related literature.

The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one sense, and that which sense of ‘knows’ is used in a knowledge ascription or denial determines, in part, the meaning (and as a result the truth conditions) of that knowledge ascription or denial. In this paper, I argue that the ambiguity theory of ‘knows’ ought to be taken seriously by those drawn to epistemic contextualism. In doing so I first argue that (...) the ambiguity theory of ‘knows’ is a distinct view from epistemic contextualism. Second, I provide independent philosophical and linguistic considerations to motivate the ambiguity theory. Third, I argue that the ambiguity theory has the same central, generally agreed upon virtues ascribed to epistemic contextualism (namely, the ability to solve certain persistent epistemological problems relating to skeptical arguments and the ability to preserve the truth of most of our everyday, ordinary usages of ‘knows’ and its cognates). Finally, I provide an ambiguity-theory-friendly account of why contextualism may be initially appealing, and why this shouldn’t dissuade us from taking the ambiguity theory seriously nonetheless. (shrink)

ABSTRACTRecent debate over the semantics and pragmatics of epistemic modals has focused on intuitions about cross-contextual truth-value assessments. In this paper, we advocate a different approach to evaluating theories of epistemic modals. Our strategy focuses on judgments of the incompatibility of two different epistemic possibility claims, or two different truth value assessments of a single epistemic possibility claim. We subject the predictions of existing theories to empirical scrutiny, and argue that existing contextualist and relativist theories are (...) unable to account for the full pattern of observed judgments. As a way of illustrating the theoretical upshot of these results, we conclude by developing a novel theory of epistemic modals that is able to predict the results. (shrink)

I argue that 'know' is only partly, though considerably, gradable. Its being only partly gradable is explained by its multi-parametrical character. That is, its truth-conditions involve different parameters, which are scalar in character, each of which is fully gradable. Robustness of knowledge may be higher or lower along different dimensions and different modes. This has little to do with whether 'know' is context-dependent, but it undermines Stanley's argument that the non-gradability of 'know' renders it non-context-dependent.

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 primary challenge from the relativist to the contextualist about epistemic modals is to explain eavesdropping data—i.e., why the eavesdropper is inclined to judge the speaker as having uttered an epistemic modal falsehood (when she is so inclined), even though the speaker’s utterance is true according to reasonable contextualist truth conditions. The issue turns in large part on the strength and shape of the data, both of which are in dispute. One complaint is that an eavesdropper’s truth value (...) judgments fluctuate with variations of non- epistemic fact (even after the relevant epistemic/information states are determined). The project here is to strengthen and reframe this complaint in a debate-neutral way, and to show how a sober contextualism can uniformly accommodate it and the standard eavesdropping data. Along the way we reject John Hawthorne’s danger-theoretic explanation of these subtleties. (shrink)

Epistemic contextualism in the style of Lewis (1996) maintains that ascriptions of knowledge to a subject vary in truth with the alternatives that can be eliminated by the subject’s evidence in a context. Schaffer (2004, 2005, 2007, 2008, 2015), Schaffer and Knobe (2012), and Schaffer and Szabo ́ (2014) hold that the question under discussion or QUD always determines these alternatives in a context. This paper shows that the QUD does not perform such a role for "know" and (...) uses this result to draw a few lessons about the metasemantics of context- sensitivity. (shrink)

According to Kuhn’s account of the nature of scientific paradigms, how one experiences the world varies drastically from one context to another depending on the accepted paradigm of the context in question. In other words, one’s pre-existing conceptual structure concerning the world not only acts as an epistemological framework for its possible understanding, but also fundamentally affects the phenomenological observations of the world as something; this latter function of the conceptual structure motivates the view that mature scientific paradigms/theories and the (...) data of scientific observation/experimentation are essentially two sides of the same coin. What is interesting, then, is that even between different historical eras that generally regarded the world in clearly incompatible ways, albeit still informed by paradigms, Kuhn still attributes scientific knowledge to each. To make sense of this, the explanatory resources of epistemological contextualism are used to specify potentially one way in which epistemic standards for knowledge must change between different historical eras for one to justifiably claim scientific knowledge within these different contexts. As we shall see, the argument for Kuhn’s account of paradigm being contextualist in character is apparently best made through the notion of doubt-driven context-shifts as actualising change in the form of P between different contexts in which “S knows that P” is asserted. As such, this paper first explores Kuhn’s account of scientific knowledge and paradigms before considering how the account can be considered contextualist in nature. Moreover, other context-concerned systems, such as Traditional, and Subject-Sensitive Invariantism, are briefly investigated to substantiate claims of what cannot be accurately ascribed to Kuhn’s epistemology.
