If language is to serve the basic purpose of communicating our attitudes, we must be constructed so as to form beliefs in those propositions that we truthfully assert on the basis of careful assent. Thus, other things being equal, I can rely on believing those things to which I give my careful assent. And so my ability to assent or dissent amounts to an ability to make up my mind about what I believe. This capacity, in tandem with a similar (...) capacity in respect of other attitudes, supports three important lessons. It means that I can know what I believe by seeing what commands my assent, that I can put aside the possibility of error in committing myself to holding such a belief, and that I can therefore perform as a person: I can organize my mind around commitments to which others are invited to hold me.

Intuitions about contextualist cases such as Cohen’s airport case pose a problem for classical anti-skeptical versions of invariantism. Recently, Tim Black, Jessica Brown, and Patrick Rysiew have argued that the classical invariantist can respond by arguing that pragmatic aspects of epistemic discourse are responsible for the relevant problematic intuitions. This paper identifies the mechanisms of conversational implicature and impliciture as the basic sources of hope for this explanatory strategy. It then argues that neither of these sources provides the classical invariantist (...) with a convincing response to the airport case and its analogs. (shrink)

This article discusses the following question: what epistemic relation must audiences bear to the content of assertions in order to gain testimonial knowledge? There is a brief discussion of why this issue is of importance, followed by two counterexamples to the most intuitive answer: that in order for an audience to gain testimonial knowledge that p they must know that the speaker has asserted p. It is then suggested that the argument generalises and can be made to work on different (...) sets of assumptions about the conditions for knowledge, and the conditions under which a proposition is asserted.

Epistemologists can be divided into two camps: those who think that nothing short of certainty or (subjective) probability 1 can warrant assertion and those who disagree with this claim. This paper addressed this issue by inquiring into the problem of setting the probability threshold required for assertion in such a way that that the social epistemic good is maximized, where the latter is taken to be the veritistic value in the sense of Goldman (Knowledge in a social world, 1999). We (...) provide a Bayesian model of a test case involving a community of inquirers in a social network engaged in group deliberation regarding the truth or falsity of a proposition $p.$ p . Results obtained by means of computer simulation indicate that the certainty rule is optimal in the limit of inquiry and communication but that a lower threshold is preferable in less idealized cases.

Do you know you are not being massively deceived by an evil demon? That is a familiar skeptical challenge. Less familiar is this question: How do you have a conception of knowledge on which the evil demon constitutes a prima facie challenge? Recently several philosophers have suggested that our responses to skeptical scenarios can be explained in terms of heuristics and biases. We offer an alternative explanation, based in learning theory. We argue that, given the evidence available to the learner, (...) it would be rational for the learner to infer an infallibilist conception of knowledge. (shrink)

Why do our intuitive knowledge ascriptions shift when a subject's practical interests are mentioned? Many efforts to answer this question have focused on empirical linguistic evidence for context sensitivity in knowledge claims, but the empirical psychology of belief formation and attribution also merits attention. The present paper examines a major psychological factor (called ?need-for-closure?) relevant to ascriptions involving practical interests. Need-for-closure plays an important role in determining whether one has a settled belief; it also influences the accuracy of one's cognition. (...) Given these effects, it is a mistake to assume that high- and low-stakes subjects provided with the same initial evidence are perceived to enjoy belief formation that is the same as far as truth-conducive factors are concerned. This mistaken assumption has underpinned contextualist and interest-relative invariantist treatments of cases in which contrasting knowledge ascriptions are elicited by descriptions of subjects with the same initial information and different stakes. The paper argues that intellectualist invariantism can easily accommodate such cases. (shrink)

ABSTRACTThis article offers a novel sceptical argument that the sensitivity-contextualist must say is sound; moreover, she must say that the conclusion of this argument is true at ordinary standards. The view under scrutiny has it that in different contexts knowledge-attributing sentences express different propositions, propositions which differ in the stretch of worlds across which the subject is required to track the truth. I identify the underlying reason for the sceptical result and argue that it makes sensitivity-contextualism irremediably flawed. Contextualists, I (...) conclude, should abandon sensitivity for some other piece of epistemic machinery. (shrink)

This paper develops a precise understanding of the thesis of moral encroachment, which states that the epistemic status of an opinion can depend on its moral features. In addition, I raise objections to existing accounts of moral encroachment. For instance, many accounts fail to give sufficient attention to moral encroachment on credences. Also, many accounts focus on moral features that fail to support standard analogies between pragmatic and moral encroachment. Throughout the paper, I discuss racial profiling as a case study, (...) arguing that moral encroachment can help us identify one respect in which racial profiling is epistemically problematic. (shrink)

This paper argues that just as full beliefs can constitute knowledge, so can properties of your credence distribution. The resulting notion of probabilistic knowledge helps us give a natural account of knowledge ascriptions embedding language of subjective uncertainty, and a simple diagnosis of probabilistic analogs of Gettier cases. Just like propositional knowledge, probabilistic knowledge is factive, safe, and sensitive. And it helps us build knowledge-based norms of action without accepting implausible semantic assumptions or endorsing the claim that knowledge is interest-relative.

Evolutionary debunking arguments claim that evolution has influenced our moral faculties in such a way that, if moral realism is true, then we have no positive moral knowledge. I present several popular objections to the standard version of this argument, then give a new EDA that has clear advantages in responding to these objections. Whereas the Standard EDA argues that evolution has selected for many moral beliefs with certain contents, this New EDA claims that evolution has selected for one belief: (...) belief in the claim that categorical reasons exist. If moral realism is true, then this claim is entailed by all positive moral claims, and belief in it is defeated due to evolutionary influence. This entails that if realism is true, then we have no positive moral knowledge. While there may be objections against this New EDA, it is much stronger than the Standard EDA, and one realists ought to worry about. (shrink)

One central debate in recent literature on epistemic normativity concerns the epistemic norm for action. This paper argues that this debate is afflicted by a category mistake: strictly speaking, there is no such thing as an epistemic norm for action. To this effect, I introduce a distinction between epistemic norms and norms with epistemic content; I argue that while it is plausible that norms of the latter type will govern action in general, epistemic norms will only govern actions characteristically associated (...) with delivering epistemic goods. (shrink)

It is wholly uncontroversial that measurements-or, more properly, propositions that are measurement reports-are often paradigmatically good cases of propositions that serve the function of evidence. In normal cases it is also obvious that stating such a report is an utterly pedestrian case of successful assertion. So, for example, there is nothing controversial about the following claims: (1) that a proposition to the effect that a particular thermometer reads 104C when properly used to determine the temperature of a particular patient is (...) evidence that the patient in question has a fever and (2) that there is nothing wrong with asserting the proposition that a particular thermometer reads 104C for appropriate reasons of communication, etc. when the thermometer has been properly used to determine the temperature of a particular patient. Here it will be shown that Timothy Williamson’s commitments to a number of principles about knowledge and assertion imply that a whole class of utterly ordinary statements like these that are used as evidence are not really evidence because they are not knowledge and so are (perversely) unassertable according to his principled commitments. This paper deals primarily with the second of these two problems and an alternative account of the norms of assertion is introduced which allows for the assertability of such measurement reports.

This article aims to provide a structural analysis of the problems related to the easy knowledge problem. The easy knowledge problem is well known. If we accept that we can have basic knowledge via a source without having any prior knowledge about the reliability or accuracy of this source, then we can acquire knowledge about the reliability or accuracy of this source too easily via information delivered by the source. Rejecting any kind of basic knowledge, however, leads into an infinite (...) regress and, plausibly, to skepticism. The article argues that the third alternative, accepting basic knowledge but rejecting easy knowledge, entails closure failure. This is obviously the case for deductive bootstrapping, but, notably, the problem also arises for inductive bootstrapping. Hence, the set of problems related to the easy knowledge problem has the structure of a trilemma. We are forced to accept easy knowledge, closure failure, or skepticism. (shrink)

The lottery paradox plays an important role in arguments for various norms of assertion. Why is it that, prior to information on the results of a draw, assertions such as, “My ticket lost,” seem inappropriate? This paper is composed of two projects. First, I articulate a number of problems arising from Timothy Williamson’s analysis of the lottery paradox. Second, I propose a relevant alternatives theory, which I call the Non-Destabilizing Alternatives Theory , that better explains the pathology of asserting lottery (...) propositions, while permitting assertions of what I call fallible propositions such as, “My car is in the driveway.” Le paradoxe de la loterie joue un rôle important dans l’argumentation visant à défendre diverses normes de l’assertion. Comment se fait-il que, avant que les résultats d’un tirage soient connus, des assertions comme «Mon billet a perdu» semblent inappropriées? Cet article se compose de deux projets. Premièrement, je relève certains problèmes issus de l’analyse du paradoxe de la loterie par Timothy Williamson. Deuxièmement, je propose une théorie des alternatives pertinentes que j’appelle la «théorie des alternatives non-déstabilisantes» , et qui explique d’une meilleure façon la pathologie de l’assertion de propositions concernant la loterie, tout en permettant des assertions faillibles, telles que «Ma voiture est dans l’entrée».

We argue, contrary to epistemological orthodoxy, that knowledge is not purely epistemic—that knowledge is not simply a matter of truth‐related factors (evidence, reliability, etc.). We do this by arguing for a pragmatic condition on knowledge, KA: if a subject knows that p, then she is rational to act as if p. KA, together with fallibilism, entails that knowledge is not purely epistemic. We support KA by appealing to the role of knowledge‐citations in defending and criticizing actions, and by giving a (...) principled argument for KA, based on the inference rule KB: if a subject knows that A is the best thing she can do, she is rational to do A. In the second half of the paper, we consider and reject the two most promising objections to our case for KA, one based on the Gricean notion of conversational implicature and the other based on a contextualist maneuver.

In light of the failure of attempts to analyse knowledge as a species of justified belief, a number of epistemologists have suggested that we should instead understand justification in terms of knowledge. This paper focuses on accounts of justification as a kind of ‘would-be’ knowledge. According to such accounts a belief is justified just in case any failure to know is due to uncooperative external circumstances. I argue against two recent accounts of this sort due to Alexander Bird and Martin (...) Smith. A further aim is to defend a more traditional conception, according to which justification is a matter of sufficiently high evidential likelihood. In particular, I suggest that this conception of justification offers a plausible account of lottery cases: cases in which one believes a true proposition – for example that one's lottery ticket will lose – on the basis of probabilistic evidence.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

The goal of this paper is to defend Simple Modest Invariantism (SMI) about knowledge from the threat presented by pragmatic encroachment. Pragmatic encroachment is the view that practical circumstances are relevant in some way to the truth of knowledge ascriptions—and if this is true, it would entail the falsity of SMI. Drawing on Ross and Schroeder’s recent Reasoning Disposition account of belief, I argue that the Reasoning Disposition account, together with Grice’s Maxims, gives us an attractive pragmatic account of the (...) connection between knowledge ascriptions and practical circumstances. This gives us the ability to explain away the data that is supposed to support pragmatic encroachment. Finally, I address three important objections to the view offered by giving a pragmatic account of when it is conversationally appropriate to cancel a conversational implicature, and discussing when sentences with true content can end up sounding false as well as cases where sentences with false content can end up sounding true.

We shall evaluate two strategies for motivating the view that knowledge is the norm of belief. The first draws on observations concerning belief's aim and the parallels between belief and assertion. The second appeals to observations concerning Moore's Paradox. Neither of these strategies gives us good reason to accept the knowledge account. The considerations offered in support of this account motivate only the weaker account on which truth is the fundamental norm of belief.

I offer a novel solution to the problem of counterfactual skepticism: the worry that all contingent counterfactuals without explicit probabilities in the consequent are false. I argue that a specific kind of contextualist semantics and pragmatics for would- and might-counterfactuals can block both central routes to counterfactual skepticism. One, it can explain the clash between would- and might-counterfactuals as in: If you had dropped that vase, it would have broken. and If you had dropped that vase, it might have safely (...) quantum tunneled to China. Two, it can explain why counterfactuals like can be true despite the fact that quantum tunneling worlds are among the most similar worlds. I further argue that this brand of contextualism accounts for the data better than other existing solutions to the problem. (shrink)

This essay develops a joint theory of rational (all-or-nothing) belief and degrees of belief. The theory is based on three assumptions: the logical closure of rational belief; the axioms of probability for rational degrees of belief; and the so-called Lockean thesis, in which the concepts of rational belief and rational degree of belief figure simultaneously. In spite of what is commonly believed, this essay will show that this combination of principles is satisfiable (and indeed nontrivially so) and that the principles (...) are jointly satisfied if and only if rational belief is equivalent to the assignment of a stably high rational degree of belief. Although the logical closure of belief and the Lockean thesis are attractive postulates in themselves, initially this may seem like a formal “curiosity”; however, as will be argued in the rest of the essay, a very reasonable theory of rational belief can be built around these principles that is not ad hoc and that has various philosophical features that are plausible independently. In particular, this essay shows that the theory allows for a solution to the Lottery Paradox, and it has nice applications to formal epistemology. The price that is to be paid for this theory is a strong dependency of belief on the context, where a context involves both the agent's degree of belief function and the partitioning or individuation of the underlying possibilities. But as this essay argues, that price seems to be affordable. (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)

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

In this paper, I explore whether there is a need for a multiplicity of norms governing belief due to differences in the objects of those beliefs, particularly the difference between persons and nonpersons. I call the view according to which there is a single epistemic norm governing belief monism, and the view that there is more than one such norm pluralism. I consider three different kinds of objections to monism that stem specifically from considerations unique to assessing the credibility of (...) persons, along with corresponding pluralist proposals. I argue not only that all of the criticisms of monism fail, but also that the proposed pluralist norms face significant problems of their own. In so doing, the aim of the paper is to clear the path for there being a single epistemic norm governing belief, despite there being important epistemic differences between how we ought to treat persons and nonpersons.

In 1990 Edward Craig published a book called Knowledge and the State of Nature in which he introduced and defended a genealogical approach to epistemology. In recent years Craig’s book has attracted a lot of attention, and his distinctive approach has been put to a wide range of uses including anti-realist metaepistemology, contextualism, relativism, anti-luck virtue epistemology, epistemic injustice, value of knowledge, pragmatism and virtue epistemology. While the number of objections to Craig’s approach has accumulated, there has been no sustained (...) attempt to develop answers to these objections. In this paper we provide answers to seven important objections in the literature. (shrink)

Nihilism is the thesis that no composite objects exist. Some ontologists have advocated abandoning nihilism in favor of deep nihilism, the thesis that composites do not existO, where to existO is to be in the domain of the most fundamental quantifier. By shifting from an existential to an existentialO thesis, the deep nihilist seems to secure all the benefits of a composite-free ontology without running afoul of ordinary belief in the existence of composites. I argue that, while there are well-known (...) reasons for accepting nihilism, there appears to be no reason at all to accept deep nihilism. In particular, deep nihilism draws no support either from the usual arguments for nihilism or from considerations of parsimony. (shrink)

Virtually everyone agrees that, even after having presented the arguments for their positions, proponents of revisionary philosophical theories are required to provide some sort of account of the conflict between their theories and what the folk believe. I examine various strategies for answering the challenge from folk belief. The examination proceeds as a case study, whose focus is eliminativism about ordinary material objects. I critically assess eliminativist attempts to explain folk belief by appeal to paraphrase, experience, and intuition.

Keith DeRose has argued that the two main problems facing subject-sensitive invariantism come from the appropriateness of certain third-person denials of knowledge and the inappropriateness of now you know it, now you don't claims. I argue that proponents of SSI can adequately address both problems. First, I argue that the debate between contextualism and SSI has failed to account for an important pragmatic feature of third-person denials of knowledge. Appealing to these pragmatic features, I show that straightforward third-person denials are (...) inappropriate in the relevant cases. And while there are certain denials that are appropriate, they pose no problems for SSI. Next, I offer an explanation, compatible with SSI, of the oddity of now you know it, now you don't claims. To conclude, I discuss the intuitiveness of purism, whose rejection is the source of many problems for SSI. I propose to explain away the intuitiveness of purism as a side-effect of the narrow focus of previous epistemological inquiries. (shrink)

This paper argues that the standard evidence for the knowledge norm of assertion can be extended to provide evidence for a corresponding knowledge norm of blame.

In a number of recent papers Duncan Pritchard argues that virtue epistemology's central ability condition—one knows that p if and only if one has attained cognitive success (true belief) because of the exercise of intellectual ability—is neither necessary nor sufficient for knowledge. This paper discusses and dismisses a number of responses to Pritchard's objections and develops a new way of defending virtue epistemology against them.

In this paper I offer a critique of the recent popular strategy of giving a contextualist account of vagueness. Such accounts maintain that truth-values of vague sentences can change with changes of context induced by confronting different entities (e.g. different pairs through a sorites series). I claim that appealing to context does not help in solving the sorites paradox, nor does it give us new insights into vagueness per se. Furthermore, the contextual variation to which the contextualist is committed is (...) problematic in various ways. For example, it yields the consequence that much of our everyday (non-soritical) reasoning is fallacious, and it renders us ignorant of what we and others have said. (shrink)

In disputes about conceptual analysis, each side typically appeals to pre-theoretical 'intuitions' about particular cases. Recently, many naturalistically oriented philosophers have suggested that these appeals should be understood as empirical hypotheses about what people would say when presented with descriptions of situations, and have consequently conducted surveys on non-specialists. I argue that this philosophical research programme, a key branch of what is known as 'experimental philosophy', rests on mistaken assumptions about the relation between people's concepts and their linguistic behaviour. The (...) conceptual claims that philosophers make imply predictions about the folk's responses only under certain demanding, counterfactual conditions. Because of the nature of these conditions, the claims cannot be tested with methods of positivist social science. We are, however, entitled to appeal to intuitions about folk concepts in virtue of possessing implicit normative knowledge acquired through reflective participation in everyday linguistic practices. (shrink)

I can, given the right conditions, transmit my knowledge to you by telling you some information. If I know the time, and if all goes well, I can bring it about that you know it too. If conditions are right, all I have to do is assert to you what time it is. Paradigmatically, speakers use assertions to transmit what they know to their hearers. Clearly, assertion and testimony are tightly connected. The nature of this connection, however, is not so (...) clear. According to many accounts, assertion has an epistemic constitutive norm. This norm appears to be able to account for some important features of testimony: first, testimonial knowledge transmission, second, the reliability of testimony, and third, the epistemic rights exchanged in cases of testimony. In this paper, however, I argue against this apparent ability. The constitutive norm of assertion, I argue, plays no role in accounts of testimonial knowledge transmission, or of the epistemic rights that testimony confers. This is especially clear whe.. (shrink)

An account of the norms of assertion is proposed which is supported by the same considerations that motivate the familiar knowledge account of those norms, but does not have a problematic consequence of the latter. This alternative account is defended against others to be found in the literature, and some larger epistemological issues it raises are considered briefly.

This paper distinguishes two ways to ?put knowledge first?. One way affirms a knowledge norm. For example, Williamson [2000] argues that one must only assert that which one knows. Hawthorne and Stanley [2008] argue that one must only treat as a reason for action that which one knows. Another way to put knowledge first affirms a determination thesis. For example, Williamson [2000] argues that what one knows determines what one is justified in believing. Hawthorne and Stanley [2008] argue that what (...) one knows determines what it is rational for one to do. This paper argues that the defender of the knowledge norms can and should reject the determination theses. For example, the rationality of acting on a partial belief cannot be explained in terms of the subject's knowledge. That's no problem for the knowledge norm, which only governs acting on full belief. (Analogously, the knowledge norm of flat-out assertion does not govern hedged assertion.) One might worry that rejecting the determination theses undermines the importance of knowing. I reply that the knowledge norms set the standard for epistemic success. The importance of success is not undermined by loosening its ties to justification and rationality. (shrink)

Arguments from "easy knowledge" are meant to refute a class of epistemological views, including foundationalism about perceptual knowledge. I present arguments from easy knowledge in their strongest form, and explain why other formulations in the literature are inferior. I criticize two features of Stewart Cohen's presentation, namely his focus on knowing that one's faculties are reliable, and his use of a Williamson-style closure principle. Rather, the issue around easy knowledge must be understood using a notion of epistemic priority. Roger White's (...) presentation is contaminated by the so-called lottery puzzle, which is best kept separate. Distinguishing basic from non-basic visual contents limits the force of the examples discussed by Cohen, White, and Crispin Wright. Finally, I present a new strategy for resisting even the best-formulated arguments from easy knowledge. (shrink)

This paper explains what’s wrong with a Hume-inspired argument for skepticism about induction. Hume’s argument takes as a premise that inductive reasoning presupposes that the future will resemble the past. I explain why that claim is not plausible. The most plausible premise in the vicinity is that inductive reasoning from E to H presupposes that if E then H. I formulate and then refute a skeptical argument based on that premise. Central to my response is a psychological explanation for how (...) people judge that if E then H without realizing that they thereby settled the matter rationally. (shrink)

Belief-credence dualism is the view that we have both beliefs and credences and neither attitude is reducible to the other. Pragmatic encroachment is the view that practical stakes can affect the epistemic rationality of states like knowledge or justified belief. In this paper, I argue that dualism offers a unique explanation of pragmatic encroachment cases. First, I explain pragmatic encroachment and what motivates it. Then, I explain dualism and outline a particular argument for dualism. Finally, I show how dualism can (...) explain the intuitions that underlie pragmatic encroachment. My basic proposal is that in high-stakes cases, it is not that one cannot rationally believe that p; instead, one ought not to rely on one's belief that p. One should rather rely on one's credence in p. I conclude that we need not commit ourselves to pragmatic encroachment in order to explain the intuitiveness of the cases that motivate it. (shrink)

In this paper, I argue that the relationship between belief and credence is a central question in epistemology. This is because the belief-credence relationship has significant implications for a number of current epistemological issues. I focus on five controversies: permissivism, disagreement, pragmatic encroachment, doxastic voluntarism, and the relationship between doxastic attitudes and prudential rationality. I argue that each debate is constrained in particular ways, depending on whether the relevant attitude is belief or credence. This means that epistemologists should pay attention (...) to whether they are framing questions in terms of belief or in terms of credence and the success or failure of a reductionist project in the belief-credence realm has significant implications for epistemology generally. (shrink)

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

This paper defends the simple view that in asserting that p, one lies iff one knows that p is false. Along the way it draws some morals about deception, knowledge, Gettier cases, belief, assertion, and the relationship between first- and higher-order norms.

Epistemic closure has been a central issue in epistemology over the last forty years. According to versions of the relevant alternatives and subjunctivist theories of knowledge, epistemic closure can fail: an agent who knows some propositions can fail to know a logical consequence of those propositions, even if the agent explicitly believes the consequence (having “competently deduced” it from the known propositions). In this sense, the claim that epistemic closure can fail must be distinguished from the fact that agents do (...) not always believe, let alone know, the consequences of what they know—a fact that raises the “problem of logical omniscience” that has been central in epistemic logic. This paper, part I of II, is a study of epistemic closure from the perspective of epistemic logic. First, I introduce models for epistemic logic, based on Lewis’s models for counterfactuals, that correspond closely to the pictures of the relevant alternatives and subjunctivist theories of knowledge in epistemology. Second, I give an exact characterization of the closure properties of knowledge according to these theories, as formalized. Finally, I consider the relation between closure and higher-order knowledge. The philosophical repercussions of these results and results from part II, which prompt a reassessment of the issue of closure in epistemology, are discussed further in companion papers. As a contribution to modal logic, this paper demonstrates an alternative approach to proving modal completeness theorems, without the standard canonical model construction. By “modal decomposition” I obtain completeness and other results for two non-normal modal logics with respect to new semantics. One of these logics, dubbed the logic of ranked relevant alternatives, appears not to have been previously identified in the modal logic literature. More broadly, the paper presents epistemology as a rich area for logical study. (shrink)

Much of the philosophical literature on causation has focused on the concept of actual causation, sometimes called token causation. In particular, it is this notion of actual causation that many philosophical theories of causation have attempted to capture.2 In this paper, we address the question: what purpose does this concept serve? As we shall see in the next section, one does not need this concept for purposes of prediction or rational deliberation. What then could the purpose be? We will argue (...) that one can gain an important clue here by looking at the ways in which causal judgments are shaped by people‘s understanding of norms. (shrink)

In the first chapter of his Knowledge and Lotteries, John Hawthorne argues that thinkers do not ordinarily know lottery propositions. His arguments depend on claims about the intimate connections between knowledge and assertion, epistemic possibility, practical reasoning, and theoretical reasoning. In this paper, we cast doubt on the proposed connections. We also put forward an alternative picture of belief and reasoning. In particular, we argue that assertion is governed by a Gricean constraint that makes no reference to knowledge, and that (...) practical reasoning has more to do with rational degrees of belief than with states of knowledge. (shrink)

The focus of this article is the question whether the notion of being in a position to know is closed under modus ponens. The question is answered negatively.

John Hawthorne’s marvelous book contains a wealth of arguments and insights based on an impressive knowledge and understanding of contemporary discussion. We can address only a small aspect of the topic. In particular, we will offer our own answers to two questions about knowledge that he discusses.

This is the second book by Baz that aims to show that a big chunk of contemporary philosophy is fundamentally misguided. His first book, When Words Are Called For: A Defense of Ordinary Language Philosophy (2012) adopted a therapeutic approach (in the Wittgensteinian style) to problems in contemporary epistemology, arguing that when properly thought through, the way philosophers talk about ‘knowing’ that something is the case ultimately does not make sense. Baz’s goal in his second book is less therapeutic and (...) more constructive: he aims to start a methodological revolution (in the Kuhnian sense)—to shake contemporary philosophers out of the unconscious habits of normal science and provoke them into making a radical change in the methods they use to do philosophy and the basic assumptions that motivate those methods.

It is a widely shared intuition that there is a close connection between knowledge-how and intentional action. In this paper, I explore one aspect of this connection: the normative connection between intending to do something and knowing how to do it. I argue for a norm connecting knowledge-how and intending in a way that parallels the knowledge norms of assertion, belief, and practical reasoning, which I call the knowledge-how norm of Intention. I argue that this norm can appeal to support (...) from arguments which parallel those for other epistemic norms, that it can deal with a number of prima facie problem cases, and that alternative conditions in a norm on intention are implausible.

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)
