Based on the brain in a vat thought experiment, skeptics argue that we cannot have certain knowledge. At the same time, we do have the intuition that we know some things with certainty. A way to justify this intuition is given by semantic contextualists who argue that the word “knows” is context sensitive. However, many have objected to the intelligibility of this claim. In response, another approach called “moderate pragmatic contextualism” was invoked, which claims that “knows” itself is not context (...) sensitive, but knowledge assertions are. I show, however, that to refute skepticism, moderate pragmatic contextualism rests on unjustified and implausible assumptions as well. Since no form of contextualism works as a response to skepticism, I argue that we should simply accept skepticism. However, I argue that skepticism is not a problem because skeptic pragmatic contextualism can offer a plausible explanation of why we have the intuition that our ordinary knowledge claims are true, even though they are not. I conclude that skeptic pragmatic contextualism offers the most plausible response to the brain in a vat thought experiment. (shrink)

Assessment relativism, as developed by John MacFarlane, is the view that the truth of our claims involving a variety of English expressions—‘tasty’, ‘knows’, ‘tomorrow’, ‘might’, and ‘ought’—is relative not only to aspects of the context of their production but also to aspects of the context in which they are assessed. Assessment relativism is thus a form of truth relativism which is offered as a new way of understanding perspectival thought and talk. In this article, I present the main theses of (...) assessment relativism, focusing in particular on highlighting the points of commonality and contrast with other forms of truth relativism. I then offer some critical remarks concerning the motivation of assessment relativism in relation to matters of taste. (shrink)

Intellectualists claim that knowing how to do something is a matter of knowing, for some w, that w is a way to do that thing. However, standard accounts fail to account for the way that knowing how sometimes seems to require ability. I argue that the way to make sense of this situation is via a ‘subject-specific’ intellectualism according to which knowing how to do something is a matter of knowing that w is a way for some relevant person to (...) do that thing, but who the relevant person is can change from context to context. If it is the utterer themselves, then knowing how will require ability, but otherwise it will not. (shrink)

Many contextualist accounts in epistemology appeal to ordinary language and everyday practice as grounds for positing a low-standards knowledge (knowledgeL) that contrasts with high-standards prevalent in epistemology (knowledgeH). We compare these arguments to arguments from the height of “ordinary language” philosophy in the mid 20th century and find that all such arguments face great difficulties. We find a powerful argument for the legitimacy and necessity of knowledgeL (but not of knowledgeH). These appeals to practice leave us with reasons to accept (...) knowledgeL in the face of radical doubts raised by skeptics. We conclude by arguing that by relegating knowledgeH to isolated contexts, the contextualist fails to deal with the skeptical challenge head-on. KnowledgeH and knowledgeL represent competing, incompatible intuitions about knowledge, and we must choose between them. A fallibilist conception of knowledge, formed with proper attention to radical doubts, can address the skeptical challenge without illicit appeal to everyday usage. (shrink)

In this paper I consider the prospects for pluralism about knowledge, that is, the view that there is a plurality of knowledge relations. After a brief overview of some views that entail a sort of pluralism about knowledge, I focus on a particular kind of knowledge pluralism I call standards pluralism. Put roughly, standards pluralism is the view that one never knows anything simpliciter. Rather, one knows by this-or-that epistemic standard. Because there is a plurality of epistemic standards, there is (...) a plurality of knowledge relations. In §1 I argue that one can construct an impressive case for standards pluralism. In §2 I clarify the relationship between standards pluralism, epistemic contextualism and epistemic relativism. In §3 I argue that standards pluralism faces a serious objection. The gist of the objection is that standards pluralism is incompatible with plausible claims about the normative role of knowledge. In §4 I finish by sketching the form that a standards pluralist response to this objection might take. (shrink)

‘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)

Relativists about knowledge ascriptions think that whether a particular use of a knowledge-ascribing sentence, e.g., “Keith knows that the bank is open” is true depends on the epistemic standards at play in the assessor’s context—viz., the context in which the knowledge ascription is being as- sessed for truth or falsity. Given that the very same knowledge-ascription can be assessed for truth or falsity from indefinitely many perspectives, relativism has a striking consequence. When I ascribe knowledge to someone (e.g., when I (...) say that, at a particular time, “Keith knows that the bank is open”), what I’ve said does not get a truth-value absolutely, but only relatively. If this semantic thesis about the word “knows” and its cognates is true, what implications would this have for epistemology, the philosophical theory of knowledge? e present aim will be to engage with this mostly unexplored question, and then to consider how the epistemological conclusions drawn might bear on the plausibility of a relativist semantics for “knows”.

An account of meta-epistemic defeaters—distinct from traditional epistemic defeaters—is motivated and defended, drawing from case studies involving epistemic error-theory and epistemic relativism. Mechanisms of traditional epistemic defeat and meta-epistemic defeat are compared and contrasted, and some new puzzles are introduced.

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)

Relativism has been, in its various guises, both one of the most popular and most reviled philosophical doctrines of our time. Defenders see it as a harbinger of tolerance and the only ethical and epistemic stance worthy of the open-minded and tolerant. Detractors dismiss it for its alleged incoherence and uncritical intellectual permissiveness. Debates about relativism permeate the whole spectrum of philosophical sub-disciplines. From ethics to epistemology, science to religion, political theory to ontology, theories of meaning and even logic, philosophy (...) has felt the need to respond to this heady and seemingly subversive idea. Discussions of relativism often also invoke considerations relevant to the very nature and methodology of philosophy and to the division between the so-called “analytic and continental” camps in philosophy. And yet, despite a long history of debate going back to Plato and an increasingly large body of writing, it is still difficult to come to an agreed definition of what, at its core, relativism is, and what philosophical import it has. This entry attempts to provide a broad account of the many ways in which “relativism” has been defined, explained, defended and criticized. (shrink)

Le contextualisme épistémique fut conçu pour offrir une solution au problème du scepticisme à partir d’une thèse sur les conditions de vérité des attributions de connaissance. J’examinerai, dans cet article, deux bases sémantiques possibles du contextualisme épistémique : (i) la norme épistémique est un constituant inarticulé; (ii) la norme épistémique est une variable cachée. Je soutiens que la thèse du constituant inarticulé est incompatible avec le contextualisme épistémique, et que la thèse de la variable cachée reste peu convaincante. L'objectif de (...) cet article est de montrer que plusieurs questions demeurent et doivent être résolues avant que le contextualisme épistémique puisse prétendre trouver une solution au problème du scepticisme.

Abstract Relativism about knowledge attributions is the view that a single occurrence of ‘S knows [does not know] that p’ may be true as assessed in one context and false as assessed in another context. It has been argued that relativism is equipped to accommodate all the data from speakers’ use of ‘know’ without recourse to an error theory. This is supposed to be relativism’s main advantage over contextualist and invariantist views. This paper argues that relativism does require the attribution (...) of semantic blindness to speakers, viz. to account for sceptical paradoxes and epistemic closure puzzles. To that end, the notion of semantic blindness is clarified by distinguishing between content-blindness and index-blindness, and it is argued that the attribution of index-blindness required by the relativist account is implausible. Along the way, it is shown that error-theoretic objections from speakers’ inter-contextual judgments fail against relativism.

Epistemic contextualism was devised mainly to provide a solution to the problem of skepticism based on a thesis about the truth conditions of knowledge attributing sentences. In this paper, I’ll examine two possible semantic bases of epistemic contextualism i.e., the epistemic standard is an unarticulated constituent, the epistemic standard is a hidden variable. After showing that the unarticulated constituent thesis is incompatible with epistemic contextualism, I’ll argue that the hidden variable account remains unconvincing. My aim in this paper is to (...) show that questions remain that must be answered before epistemic contextualism can claim success in the project of resolving skepticism. (shrink)

John MacFarlane explores how we might make sense of the idea that truth is relative. He provides new, satisfying accounts of parts of our thought and talk that have resisted traditional methods of analysis, including what we mean when we talk about what is tasty, what we know, what will happen, what might be the case, and what we ought to do.

The basic idea of conversational contextualism is that knowledge attributions are context sensitive in that a given knowledge attribution may be true if made in one context but false if made in another, owing to differences in the attributors’ conversational contexts. Moreover, the context sensitivity involved is traced back to the context sensitivity of the word “know,” which, in turn, is commonly modelled on the case either of genuine indexicals such as “I” or “here” or of comparative adjectives such as (...) “tall” or “rich.” But contextualism faces various problems. I argue that in order to solve these problems we need to look for another account of the context sensitivity involved in knowledge attributions and I sketch an alternative proposal. (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)

Philosophers on all sides of the contextualism debates have had an overly narrow conception of what semantic context sensitivity could be. They have conflated context sensitivity (dependence of truth or extension on features of context) with indexicality (dependence of content on features of context). As a result of this conflation, proponents of contextualism have taken arguments that establish only context sensitivity to establish indexicality, while opponents of contextualism have taken arguments against indexicality to be arguments against context sensitivity. Once these (...) concepts are carefully pulled apart, it becomes clear that there is conceptual space in semantic theory for nonindexical forms of contextualism that have many advantages over the usual indexical forms. (shrink)

Epistemic contextualism—the view that the content of the predicate ‘know’ can change with the context of utterance—has fallen into considerable disrepute recently. Many theorists have raised doubts as to whether ‘know’ is context-sensitive, typically basing their arguments on data suggesting that ‘know’ behaves semantically and syntactically in a way quite different from recognised indexicals such as ‘I’ and ‘here’ or ‘flat’ and ‘empty’. This paper takes a closer look at three pertinent objections of this kind, viz. at what I call (...) the Error-Theory Objection, the Gradability Objection and the Clarification-Technique Objection. The paper concludes that none of these objections can provide decisive evidence against contextualism. (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.

Recent years have seen an explosion of interest in the semantics of knowledge-attributing sentences, not just among epistemologists but among philosophers of language seeking a general understanding of linguistic context sensitivity. Despite all this critical attention, however, we are as far from consensus as ever. If we have learned anything, it is that each of the standard views—invariantism, contextualism, and sensitive invariantism—has its Achilles’ heel: a residuum of facts about our use of knowledge attributions that it can explain only with (...) special pleading. This is not surprising if, as I will argue, there is a grain of truth in each of these views. (shrink)

In recent years, a number of new trends have seen light at the intersection of semantics and philosophy of language. They are meant to address puzzles raised by the context-sensitivity of a variety of natural language constructions, such as knowledge ascriptions, belief reports, epistemic modals, indicative conditionals, quantifier phrases, gradable adjectives, temporal constructions, vague predicates, moral predicates, predicates of personal taste. A diversity of labels have consequently emerged, such as 'contextualism', 'indexicalism', 'invariantism', 'literalism', 'minimalism', and 'relativism', variously qualified. The goal (...) of this essay is to pinpoint the issues that lie at the heart of the recent debates, clarify what is at stake, and provide a snapshot of the current theoretical landscape. (shrink)

It is argued that neither contextualism nor relativism can provide a satisfying semantics of knowledge ascriptions. According to contextualism, the truth conditions of knowledge ascriptions of the form “S knows that p” vary with the epistemic standards operative in the contexts of utterance. These epistemic standards are determined, in particular, by the speaker’s stakes with regard to p or the consideration of error-possibilities. It is shown that the absolute concept of utterance truth together with a knowledge rule of assertion lead (...) to certain unassertable truths in contextualism and to counterintuitive results with regard to certain cross-context knowledge ascriptions. Although utterance truth is relativized to contexts of assessment in relativist accounts of knowledge, relativism still makes inadequate semantic predictions. In particular, relativism runs into problems in cases where the context of assessment is lower than the context of utterance. It is finally argued that invariantist accounts, according to which the truth conditions of knowledge ascriptions do neither vary with the context of utterance nor the context of assessment, but are determined by objective features given in the situation in which the knowledge claim is made, are better suited for modelling the semantics of knowledge ascriptions. Besides the fact that stakes or the consideration of error-possibilities can have an influence on the belief in a proposition, they have no further bearing on the truth conditions of knowledge ascriptions.

My aim in the paper will be to better understand what faultless disagreement could possibly consist in and what speakers disagree over when they faultlessly do so. To that end, I will first look at various examples of faultless disagreement. Since I will eventually claim that different forms of faultless disagreement can be modeled semantically on different forms of context-sensitivity I will, in a second step, discuss three different semantic accounts that all promise to successfully accommodate certain forms of context-sensitivity: (...) Indexical Contextualism, Nonindexcal Contextualism and Radical Relativism. Focussing on the controversy between Indexical and Nonindexical Contextualists the remainder of the paper will be devoted to the question which theory is best suited to handle what kind of disagreement.

One of the most important “folk” anti-realist thoughts about certain areas of our thought and discourse—basic taste, for instance, or comedy—is that their lack of objectivity crystallises in the possibility of “faultless disagreements”: situations where one party accepts P, another rejects P, and neither is guilty of any kind of mistake of substance or shortcoming of cognitive process. On close inspection, however, it proves challenging to make coherent sense of this idea, and a majority of theorists have come to reject (...) it as incoherent. There are two significant exceptions in the contemporary literature: relativists often hold it up as something of a coup for their view that it can make straightforward sense of faultless disagreement; and the author of this paper has argued (Wright 2006) that making judicious intuitionistic revisions to classical logic can provide resources that suffice to stabilise the notion. The present paper argues that neither relativism nor intuitionism in fact provides a satisfactory account and indicates how an alethic pluralist framework enables us to do better. (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)

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.

Skepticism seems to have excessive consequences: the impossibility of successful enquiry and differentiated judgment. Yet if skepticism could avoid these consequences, it would seem idle. I offer an account of moderate skepticism that avoids both problems. Moderate skepticism avoids excessiveness because skeptical reflection and ordinary enquiry are immune from one another: a skeptical hypothesis is out of place when raised with in an ordinary enquiry. Conversely, the result of an ordinary enquiry cannot be used to disprove skepticism. This ‘immunity’ can (...) be explained by theories such as contextualism, or sensitive invariantism. Moderate skepticism avoids idleness, because it can eliminate dogmatic elements from our commitments. An analogy is used to illustrate this: Consider someone who is rootless—someone who doesn't have a home. She won't take this conclusion to undermine her judgment that she is flying home for the holidays—even if she is sleeping in the guest bedroom. Similarly, a skeptic won't take the skeptical conclusion to undermine ordinary claims to know. Yet concluding that one is rootless is significant: it can shape one's commitments; for instance it can check one's nationalism. Similarly, accepting the skeptical conclusion is significant; it can undermine dogmatic commitments and ultimately bring about intellectual catharsis. (shrink)

I argue that sentence contents should be assigned truth-values relative to parameters other than a possible world only if those parameters are fixed by the context of assessment rather than the context of use. Standard counterexamples, including tense, de se attitudes, and knowledge ascriptions, all admit of alternative analyses which do not make use of such parameters. Moreover, allowing such indices greatly complicates the task of defining disagreement, and forces an odd separation between what is true, and what someone has (...) truthfully said. If non-world indices are always fixed by the context of assessment, a characterization of semantic theories as ?relativist? in terms of assessment-sensitivity converges with a characterization in terms of sensitivity to non-world indices. More tentatively, I suggest that even a possible world index, when used in the assignment of truth-values to sentence contents, should be fixed by the context of assessment, not the context of use. This eliminates MacFarlane's category of ?non-indexical contextualism?, and results in a system in which parameters fixed by the context of use are used only in the assignment of contents to linguistic expressions, and parameters used in the assignment of truth-values to contents are uniformly fixed by the context of assessment.

That knowledge ascriptions exhibit some form of sensitivity to context is uncontroversial. How best to account for the context-sensitivity at issue, however, is the topic of heated debates. A certain version of nonindexical contextualism seems to be a promising option. Even so, it is incumbent upon any contextualist account to explain in what way and to what extent the epistemic standard operative in a particular context of epistemic evaluation is affected by non-epistemic factors. In this paper, I investigate how non-epistemic (...) factors come into play when knowledge is ascribed. I argue that knowledge ascriptions often serve the purpose of providing actionable information. This, in turn, requires that epistemic interests be balanced against non-epistemic interests. Moreover, it raises the question of whose interests matter, those of the ascriber, the addressee, or the subject of ascription. Eventually, an answer to the question is suggested. (shrink)
