In this paper, I explain the curious role played by the Argument from Absolute Terms in Peter Unger's book Ignorance, I provide a critical presentation of the argument, and I consider some outstanding issues and the argument’s contemporary significance.

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.

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)

The paper defends Cartesian skepticism by an argument relying on internalism and infallibilism. It argues that this sort of skepticism gives the best explanation of our intuitions and ordinary epistemic practices.

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)

General contrastivism holds that all claims of reasons are relative to contrast classes. This approach applies to explanation (reasons why things happen), moral philosophy (reasons for action), and epistemology (reasons for belief), and it illuminates moral dilemmas, free will, and the grue paradox. In epistemology, contrast classes point toward an account of justified belief that is compatible with reliabilism and other externalisms. Contrast classes also provide a model for Pyrrhonian scepticism based on suspending belief about which contrast class is relevant. (...) This view contrasts with contextualism, invariantism, and Schaffer's contrastivism. (shrink)

Many people follow Grice in thinking that all conversational implicatures are cancellable. And often enough, they use this insight as a test for conversational implicatures. If you want to find out whether something is a conversational implicature, the test has it, you should ask yourself whether the thing in question is cancellable; if you find that it is not cancellable, you can infer that it is not a conversational implicature. If you find that it is cancellable, you can infer that (...) it might well be a conversational implicature and that you should now do further testing. Various philosophers and linguists have questioned the test however. Some have held that Grice's cancellability claim is subject to counterexamples and that the test is not reliable. Others have argued that even though Grice's claim can be defended against the examples in question, the test is not as informative as people have hoped. This article provides an overview of the recent discussion on the cancellability test and suggests a way forward. (shrink)

Sentences containing predicates of personal taste exhibit two striking features: whether they are true seems to lie in the eye of the beholder and whether they are true can be—and often is—subject to disagreement. In the last decade, there has been a lively debate about how to account for these two features. In this paper, I shall argue for two claims: first, I shall show that even the most promising approaches so far offered by proponents of so-called indexical contextualism fail (...) to account for the disagreement feature. They might be able to account for some disagreement data, but they have trouble accounting for two kinds of disagreement data that caused the estrangement from indexical contextualism and the migration to relativism in the first place: the denial and the retraction data. Second, I shall show that we still do not have to abandon indexical contextualism, because what I shall call the superiority approach—a new pragmatically extended version of indexical contextualism—can very well account for the data. (shrink)

How should the contrastivist formulate closure? That is, given that knowledge is a ternary contrastive state Kspq (s knows that p rather than q), how does this state extend under entailment? In what follows, I will identify adequacy conditions for closure, criticize the extant invariantist and contextualist closure schemas, and provide a contrastive schema based on the idea of extending answers. I will conclude that only the contrastivist can adequately formulate closure.

The status of the knowledge iteration principles in the account provided by Lewis in “Elusive Knowledge” is disputed. By distinguishing carefully between what in the account describes the contribution of the attributor’s context and what describes the contribution of the subject’s situation, we can resolve this dispute in favour of Holliday’s claim that the iteration principles are rendered invalid. However, that is not the end of the story. For Lewis’s account still predicts that counterexamples to the negative iteration principle ) (...) come out as elusive: such counterexamples can occur only in possibilities which the attributors of knowledge are ignoring. This consequence is more defensible than it might look at first sight. (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.

I offer a critical treatment of the contrastivist response to the problem of radical scepticism. In particular, I argue that if contrastivism is understood along externalist lines then it is unnecessary, while if it is understood along internalist lines then it is intellectually dissatisfying. Moreover, I claim that a closer examination of the conditions under which it is appropriate to claim knowledge reveals that we can accommodate many of the intuitions appealed to by contrastivists without having to opt for this (...) particular brand of epistemological revisionism. (shrink)

In this paper, we propose and justify the cross‐linguistic study of the concept of truth through empirical studies of truth predicates, with results of such studies. We first conceptually explore the possibility of cross‐linguistic disagreement about truth purely due to linguistic norms governing truth predicates, which may imply a kind of pluralism about the concept of truth. We then consider the conditions under which we would be justified in inferring this sort of pluralism from the fact of such cross‐linguistic disagreement. (...) Next, we report results of three studies on the use of English “is true” and Japanese two truth predicates, as well as “is correct” and its Japanese counterpart. We then report another set of studies using a different vignette, where the radical cross‐linguistic difference observed in earlier studies disappeared. These data together suggest that the moral‐political factor in the truth‐bearer (utterance) strongly affects the uses of Japanese truth predicates but not those of English. Finally, we will discuss the implications of the studies and results reported here, and the empirical possibility of what we call lexical alethic pluralism, for debates over relativism, theories of meaning, and the deflationary and inflationary theories of truth.

Discrimination is a central epistemic capacity but typically, theories of discrimination only use discrimination as a vehicle for analyzing knowledge. This paper aims at developing a self-contained theory of discrimination. Internalist theories of discrimination fail since there is no compelling correlation between discriminatory capacities and experiences. Moreover, statistical reliabilist theories are also flawed. Only a modal theory of discrimination is promising. Versions of sensitivity and adherence that take particular alternatives into account provide necessary and sufficient conditions on discrimination. Safety in (...) contrast is not sufficient for discrimination as there are cases of safety that are clearly instances of discrimination failure. The developed account of discrimination between objects will be extended to discrimination between kinds and between types. (shrink)

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)

Any good theory of knowledge ascriptions should explain and predict our judgments about their felicity. I argue that any such explanation must take into account a distinction between three ways of using knowledge ascriptions: to suggest acceptance of the embedded proposition, to explain or predict a subject's behavior or attitudes, or to understand the relation of knowledge as such. The contextual effects on our judgments about felicity systematically differ between these three types of uses. Using such a distinction is, in (...) principle, open to both contextualist and pragmatic invariantist accounts of knowledge ascriptions. However, there are some implications pertaining to the use of the “method of cases” in the debate about knowledge ascriptions. (shrink)

Early in his career and in critical engagement with ordinary language philosophy, John Mackie developed the roots of a methodology that would be fundamental to his thinking: Mackie argues that we need to clearly separate the conceptual analysis which determines the meaning of an ordinary term and the factual analysis which is concerned with the question what, if anything, our language corresponds to in the world. I discuss how Mackie came to develop this distinction and how central ideas of his (...) philosophy are based on it. Using the examples of Mackie’s moral skepticism and his work on Locke’s theory of perception I show how his methodology opens the door to error theories but can also support more positive claims. Finally, I put Mackie’s methodology in a historical perspective and argue that in cases like the Gettier debate, we can use it to cast light on the vagueness of the underlying methodology in some philosophical debates. (shrink)

Keith DeRose and Stewart Cohen object to the fallibilist strand of pragmatic invariantism regarding knowledge ascriptions that it is committed to non-cancelable pragmatic implications. I show that this objection points us to an asymmetry about which aspects of the conveyed content of knowledge ascriptions can be canceled: we can cancel those aspects that ascribe a lesser epistemic standing to the subject but not those that ascribe a better or perfect epistemic standing. This situation supports the infallibilist strand of pragmatic invariantism (...) according to which knowledge semantically requires absolute certainty but this claim is often pragmatically weakened: it turns out that exactly those aspects of the conveyed content are cancelable that this view claims are pragmatic. I also argue that attributor contextualism and relativism do not have an alternative explanation of this phenomenon. (shrink)

The skeptical puzzle consists of three independently plausible yet jointly inconsistent claims: (A) S knows a certain ordinary proposition op; (B) S does not know the denial of a certain skeptical hypothesis sh; and (C) S knows that op only if S knows that not- sh. The variantist solution (to the skeptical puzzle) claims that (A) and not-(B) are true in the ordinary context, but false in the skeptical one. Epistemic contextualism has offered a standards-variantist solution, which is the most (...) prominent variantist solution on the market. In this paper, I argue that the standards-variantist solution in general (and the contextualist solution in particular) is epistemically uninteresting. Proponents of the variantist solution should opt for the position-variantist solution instead. I will discuss some important implications of my findings. (shrink)

I develop one partial explanation of the origins of our fallibilist intuitions about knowledge in ordinary language fallibilism and argue that this explanation indicates that our epistemic methodology should be more impartial and theory-neutral. First, I explain why the so-called Moorean constraint (cf. Hawthorne 2005, 111) that encapsulates fallibilist intuitions is fallibilism’s cornerstone. Second, I describe a pattern of fallibilist reasoning in light of the influential dual processing and heuristics and biases approach to cognition (cf. Kahneman 2011; Thaler and Sunstein (...) 2008; Evans 2017). I suggest that this pattern of reasoning involves the question-substitution heuristic, the availability and representativeness heuristics, the focusing bias as well as framing effects, priming and the anchoring and adjusting heuristic. Third, I argue that this fallibilist pattern of reasoning is methodologically dubious because it involves a vicious circularity and briefly outline an alternative, more impartial and theory-neutral abductive methodology for the theory of knowledge. Finally, I briefly explain how this analysis sheds light on the ordinary language fallibilism of Moore (1939), Austin (1961), Wittgenstein (1969) and Chisholm (1982). (shrink)

Skeptical invariantism does not account for the intuitive connections between knowledge, assertion, and practical reasoning and this constitutes a significant problem for the position because it does not save corresponding epistemic appearances (cf. Hawthorne (2004:131-5)). Moreover, it is an attraction of fallibilist over infallibilist-skeptical views that they can easily account for the epistemic appearances about the connections between knowledge, assertion, and practical reasoning (cf. Williamson (2000:249-255)). Call this argument ‘the argument from the knowledge norm’. I motivate and develop a Humean, (...) pragmatist strategy for a skeptical response to ‘the argument from the knowledge norm’. Afterwards I outline a ‘toy’ version of pragmatic skepticism that can implement the strategy and save our everyday practice of assertion and practical reasoning. To this effect, I distinguish between assertibility conditions and truth conditions for ‘know’ and suggest that while assertibility conditions are pragmatic conditions sensitive to practical exigencies, truth conditions are semantic conditions sensitive only to truth. I briefly respond to three objections and conclude that pragmatic skepticism is resourceful enough to save our everyday practice of (fallibilist) assertion and practical reasoning and, hence, pay some due respect to corresponding epistemic appearances. (shrink)

How should we account for the contextual variability of knowledge claims? Many philosophers favour an invariantist account on which such contextual variability is due entirely to pragmatic factors, leaving no interesting context-sensitivity in the semantic meaning of ‘know that.’ I reject this invariantist division of labor by arguing that pragmatic invariantists have no principled account of embedded occurrences of ‘S knows/doesn’t know that p’: Occurrences embedded within larger linguistic constructions such as conditional sentences, attitude verbs, expressions of probability, comparatives, and (...) many others, I argue, give rise to a threefold problem of embedded implicatures. (shrink)

This paper introduces and defends the paradigm response to external world skepticism. To understand it, consider an analogy. One of the hallmarks of being a bird is an ability to fly. A penguin lacks this hallmark and thus fails to be a paradigm bird. Likewise, there are various hallmarks of knowledge. Some of your external world beliefs lack some of these hallmarks, and thus fail to be paradigm cases of knowledge. Just as the inability of penguins to fly doesn’t prevent (...) them from being birds, likewise the lack of these hallmarks doesn’t prevent your beliefs from being knowledge. It just prevents them from being paradigm cases thereof. (shrink)

Grice’s Razor is a principle of parsimony which states a preference for linguistic explanations in terms of conversational implicature, to explanations in terms of semantic context-dependence. Here I propose a Gricean theory of knowledge attributions, and contend on the basis of Grice’s Razor that it is superior to contextualism about ‘knows’.

The truth of skepticism would be depressing and impractical. Our beliefs would be groundless, we would know nothing (or almost nothing) about the world around us, and epistemic success would likely be impossible. But do these negative consequences have any bearing on the truth of skepticism? According to many scholars, they do not. The impractical consequences of skepticism are typically regarded as orthogonal to its truth. For this reason, pragmatic resolutions to skepticism are regularly dismissed. I will argue, however, that (...) skepticism is implausible because it is impractical. In particular, skepticism is implausible because it goes against the point of epistemic evaluation. (shrink)

In this paper I consider the plausibility of developing anti-skepticism by framing the question in linguistic terms: instead of asking whether we know, we ask what falls within the extension of the word “know”. I first trace two previous attempts to develop anti-skepticism in this way, from Austin (particularly as presented by Kaplan) and from epistemic contextualism, and I present reasons to think that both approaches are unsuccessful. I then focus on a more recently popular attempt to develop anti-skepticism from (...) the “function-first” approach associated with Craig, which I also show to be problematic. I then argue that the apparent prima facie plausibility of fighting skepticism on linguistic grounds is due to a methodological spill-over from linguistics. Once we recognize this, it becomes clear that debate around skepticism should not be conducted in linguistic terms. (shrink)

The paper critically examines an objection to epistemic contextualism recently developed by Elke Brendel and Peter Baumann, according to which it is impossible for the contextualist to know consistently that his theory is true. I first present an outline of contextualism and its reaction to scepticism. Then the necessary and sufficient conditions for the knowability problem to arise are explored. Finally, it will be argued that contextualism does not fulfil these minimal conditions. It will be shown that the contrary view (...) is based on a misunderstanding of what contextualists are claiming. (shrink)

In this paper, I will discuss what I will call “skeptical pragmatic invariantism” as a potential response to the intuitions we have about scenarios such as the so-called bank cases. SPI, very roughly, is a form of epistemic invariantism that says the following: The subject in the bank cases doesn’t know that the bank will be open. The knowledge ascription in the low standards case seems appropriate nevertheless because it has a true implicature. The goal of this paper is to (...) show that SPI is mistaken. In particular, I will show that SPI is incompatible with reasonable assumptions about how we are aware of the presence of implicatures. Such objections are not new, but extant formulations are wanting for reasons I will point out below. One may worry that refuting SPI is not a worthwhile project given that this view is an implausible minority position anyway. To respond, I will argue that, contrary to common opinion, other familiar objections to SPI fail and, thus, that SPI is a promising position to begin with. (shrink)

Russell ([2022]. “Fancy Loose Talk About Knowledge.” Inquiry 65: 789–820.) defends a novel form of skeptical invariantism, according to which knowledge ascriptions are hardly ever true because they are so demanding, but nonetheless are ordinarily used loosely to communicate truths, where the felicity of loose talk is relative to the context of assessment as well as the context of use. I argue that while there is very good reason to believe that ‘know’ is a demanding term commonly used loosely, we (...) need not and should not conclude that loose use is assessment relative or that knowledge ascriptions are hardly ever true. (shrink)

Grice’s Razor is a methodological principle that many philosophers and linguists have used to help justify pragmatic explanations of linguistic phenomena over semantic explanations. A number of authors in the debate over contextualism argue that an invariant semantics together with Grice’s (1975) conversational principles can account for the contextual variability of knowledge claims. I show here that the defense of Grice’s Razor found in these “Gricean invariantists,” and its use against epistemic contextualism, display all the problems pointed out earlier in (...) Davis (1998). The everyday variation in acceptable knowledge claims is better explained in terms of implicature than indexicality, but general conversational principles shed little light on whether ‘know’ is used hyperbolically, meiotically, or loosely in a context, although this issue is crucial in deciding what if anything ‘S knows p’ implicates. I present reasons favoring an account of the representative bank case in terms of loose use, making clear how they differ from Grice’s Razor. (shrink)

In “How to Be an Infallibilist,” Julien Dutant (2016, 149) presents a simple and seemingly plausible argument that knowledge requires infallible belief—roughly, belief that could not be mistaken. As Dutant recognizes, infallibilism is almost universally dismissed, in large part because it seems to rule out any knowledge of the physical world. He seeks to show how we can be an Infallibilist without being a skeptic, based on the assumption that knowledge has a safety condition. I critically examine each line of (...) Dutant’s argument, showing that the argument is unsound on any plausible interpretation. I also question the idea that knowledge cannot be the conjunction of true belief and a nonfactive condition, that any belief about the physical world could not be false, and that any nonskeptical alternative to infallibilism would have to allow knowledge of chancy outcomes. I briefly suggest that a fallibilist account can be strict enough to satisfy the Infallibilist’s quest for certainty. (shrink)

Contextualists such as Cohen and DeRose claim that the truth conditions of knowledge attributions vary contextually, in particular that the strength of epistemic position required for one to be truly ascribed knowledge depends on features of the attributor's context. Contextualists support their view by appeal to our intuitions about when it's correct (or incorrect) to ascribe knowledge. Someone might argue that some of these intuitions merely reflect when it is conversationally appropriate to ascribe knowledge, not when knowledge is truly ascribed, (...) and so try to accommodate these intuitions even on an invariantist view. DeRose (Blackwell Guide to Epistemology, 1998; Philosophical Review, 2002) argues that any such 'warranted assertibility manoeuvre', or 'WAM', against contextualism is unlikely to succeed. Here, I argue that his objections to a WAM against contextualism are not persuasive and offer a pragmatic account of the data about ascriptions of knowledge. (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)

In recent work on the semantics of ‘knowledge’-attributions, a variety of accounts have been proposed that aim to explain the data about speaker intuitions in familiar cases such as DeRose’s Bank Case or Cohen’s Airport Case by means of pragmatic mechanisms, notably Gricean implicatures. This paper argues that pragmatic explanations of the data regarding ‘knowledge’-attributions are unsuccessful and concludes that in explaining those data we have to resort to accounts that (a) take those data at their semantic face value (Epistemic (...) Contextualism, Subject-Sensitive Invariantism or Epistemic Relativism), or (b) reject them on psychological grounds (Moderate Insensitive Invariantism). To establish this conclusion, the paper relies solely upon widely accepted assumptions about pragmatic theory, broadly construed, and on the Stalnakerian insight that linguistic communication takes place against the backdrop of a set of mutually accepted propositions: a conversation’s common ground. (shrink)

The paper explicates a new way to model the context-sensitivity of 'knows', namely a way that suggests a close connection between the content of 'knows' in a context C and what is pragmatically presupposed in C. After explicating my new approach in the first half of the paper and arguing that it is explanatorily superior to standard accounts of epistemic contextualism, the paper points, in its second half, to some interesting new features of the emerging account, such as its compatibility (...) with the intuitions of Moorean dogmatists. Finally, the paper shows that the account defended is not subject to the most prominent and familiar philosophical objections to epistemic contextualism discussed in the recent literature. (shrink)

Subject sensitive invariantism is the view that whether a subject knows depends on what is at stake for that subject: the truth-value of a knowledge-attribution is sensitive to the subject's practical interests. I argue that subject sensitive invariantism cannot accept a very plausible principle for memory to transmit knowledge. I argue, furthermore, that semantic contextualism and contrastivism can accept this plausible principle for memory to transmit knowledge. I conclude that semantic contextualism and contrastivism are in a dialectical position better than (...) subject sensitive invariantism is. (shrink)

There’s something deeply right in the idea that knowledge requires an ability to discriminate truth from falsity. Failing to incorporate some version of the discrimination requirement into one’s epistemology generates cases of putative knowledge that are at best problematic. On the other hand, many theories that include a discrimination requirement thereby appear to entail violations of closure. This prima facie tension is resolved nicely in Jonathan Schaffer’s contrastivism, which I describe herein. The contrastivist take on relevant alternatives is implausible, however, (...) and this then threatens to undermine contrastivism’s anti-skeptical results. (shrink)

Epistemological contextualism ‐ the claim that the truth‐value of knowledge‐attributions can vary with the context of the attributor ‐ has recently faced a whole series of objections. The most serious one, however, has not been discussed much so far: the factivity objection. In this paper, I explain what the objection is and present three different versions of the objection. I then show that there is a good way out for the contextualist. However, in order to solve the problem the contextualist (...) has to accept a relationalist version of contextualism. (shrink)

I argue that to know that a proposition is true one must have justification for being certain that the proposition is true. That is, one must have infallible epistemic justification for believing the proposition. It is widely accepted among epistemologists that we rarely, if ever, have such strong justification for our beliefs. It follows that there is precious little that we know. That conclusion is unacceptable to many philosophers. I argue that the positions that lead to the skeptical conclusion are (...) well-motivated and that the skeptical conclusion is implicitly accepted by ordinary speakers. My dissertation has three main components: a metaphilosophical position, an epistemological position, and an error theory. First, the metaphilosophical position. One very important part of philosophy is the analysis of our ordinary concepts. Analysis of our concepts begins with reflecting on what we are inclined to say about various actual and possible cases when considered under specific descriptions. This traditional method has recently come under attack, due in part to the rise of semantic externalism. I agree with externalists that if ‘meaning is reference’ then there is little reason to think reflecting on our concepts from the armchair will provide insight to the nature of the concepts we investigate. I defend a version of semantic internalism which grounds meaning in factors with which subjects are directly acquainted. That view supports the traditional methodology. Furthermore, as the goal of philosophical analysis is to accurately describe concepts of philosophical interest, the only kind of objection that could be decisive against a proposed analysis is that it does not correctly describe our concept. That opens the door to a skeptical analysis of knowledge. Second, the epistemological position. I argue that the unacceptability of sentences of the form “S knows that p but it is possible for S that not-p” is best explained by the hypothesis that our concept of knowledge requires having justification for being certain that what one believes is true. I offer as a criterion of justified certainty the idea that when one knows a proposition is true, one is in a position to decisively answer questions about one’s knowledge of that proposition. I survey a number of competing theories of knowledge and show that they allow for the possibility of knowledge when one fails my criterion of decisive answerability. Those views fail my criterion because according to those views there is nothing the subject is aware of that guarantees for the subject that the allegedly known proposition is true. On that basis, I contend that knowledge is direct awareness of the factors that constitute the truth of the proposition one believes. Third, the error theory. Of course, we rarely have direct awareness of the factors that constitute the truth of the propositions we believe. So, our knowledge attributions are generally false. Yet, they are overwhelmingly natural to make. I argue that competent speakers are often quick to recognize knowledge attributions as a kind of ‘loose talk’ akin to the way we loosely ascribe geometric properties to ordinary objects. We regularly call objects ‘square’ that are not even close to being square, and we are quick to recognize this when challenged. I argue that we do this because we are so accustomed to communicating using strict language to make false claims that we often do not attend to the literal falsity of what we are saying. While we accept very demanding standards for knowledge, the phenomenon of recognizing that our knowledge claims are regularly false is as pervasive as our use of loose speech. (shrink)

Contrastivism about knowledge is the view that one does not just know some proposition. It is more adequate to say that one knows something rather than something else: I know that I am looking at a tree rather than a bush but I do not know that I am looking at a tree rather than a cleverly done tree imitation. Knowledge is a three-place relation between a subject, a proposition and a contrast set of propositions. There are several advantages of (...) a contrastivist view but also certain problems with it.
