This paper has two aims: it develops and defends a fully-fledged account of the epistemic normativity of conjecture it goes sharply against orthodoxy, in arguing that conjecture is epistemically more demanding than assertion. According to the view defended here, one’s conjecture that p is permissible only if one knows that one has warrant, but not sufficient warrant to believe that p. I argue for my account on three independent grounds: the Bach and Harnish account of the nature of communicative speech (...) acts, the plausible normative relation between assertion and other constatives, and the normativity of belief in conjunction with constatives’ epistemic function.

ABSTRACTThis paper discusses the permissibility of exclusively relying on a procedural objectivity model for news reporting, from the perspective of the normativity of informative speech acts. It is argued that, with the exception of urgency situations, the paradigmatic application of procedural objectivity is in breach of the relevant norms.

Taking Per Martin-Löf’s constructive type theory as a starting-point a theory of assertion is developed, which is able to account for the epistemic aspects of the speech act of assertion, and in which it is shown that assertion is not a wide genus. From a constructivist point of view, one is entitled to assert, for example, that a proposition A is true, only if one has constructed a proof object a for A in an act of demonstration. One thereby has (...) grounded the assertion by an act of demonstration, and a grounding account of assertion therefore suits constructive type theory. Because the act of demonstration in which such a proof object is constructed results in knowledge that A is true, the constructivist account of assertion has to ward off some of the criticism directed against knowledge accounts of assertion. It is especially the internal relation between a judgement being grounded and its being known that makes it possible to do so. The grounding account of assertion can be considered as a justification account of assertion, but it also differs from justification accounts recently proposed, namely in the treatment of selfless assertions, that is, assertions which are grounded, but are not accompanied by belief.

In this paper, I propose that one can have reason to choose a few tickets in a very large lottery and arbitrarily believe of them that they will lose. Such a view fits nicely within portions of Lehrer's theory of rational acceptance. Nonetheless, the reasonability of believing a lottery ticket will lose should not be taken to constitute the kind of justification required in an analysis of knowledge. Moreover, one should not accept what one takes to have a low chance (...) of being true. Accordingly, one should take care not to believe of too many tickets that they are to lose. Finally, while arbitrariness is no absolute barrier to epistemic reasonability, one may not be able to believe that one's lottery ticket will lose if one cannot regard oneself as knowing it will lose.

Gareth Evans famously affirmed an explanatory connection between answering the question whether p and knowing whether one believes that p. This is commonly interpreted in terms of the idea that judging that p constitutes an adequate basis for the belief that one believes that p. This paper formulates and defends an alternative, more modest interpretation, which develops from the suggestion that one can know that one believes that p in judging that p.

First-person present-tense self-ascriptions of belief are often used to tell others what one believes. But they are also naturally taken to express the belief they ostensibly report. I argue that this second aspect of self-ascriptions of belief holds the key to making the speaker's knowledge of her belief, and so the authority of her act of telling, intelligible. For a basic way to know one's beliefs is to be aware of what one is doing in expressing them. This account suggests (...) that we need to reconsider the terms of the standard alternative between “epistemic” and “non-epistemic” explanations of first-person authority. In particular, the natural view that the authority we accord to self-ascriptions reflects a distinctive way we have of knowing our own beliefs should not be conflated with the traditional epistemological thesis that such knowledge reflects a private “mode of access”.

Alston, Searle, and Williamson advocate the restrictive model of assertion , according to which certain constitutive assertoric norms restrict which propositions one may assert. Sellars and Brandom advocate the dialectical model of assertion , which treats assertion as constituted by its role in the game of giving and asking for reasons. Sellars and Brandom develop a restrictive version of the dialectical model. I explore a non-restrictive version of the dialectical model. On such a view, constitutive assertoric norms constrain how one (...) must react if an interlocutor challenges one's assertion, but they do not constrain what one should assert in the first place. I argue that the non-restrictive dialectical perspective can accommodate various linguistic phenomena commonly taken to support the restrictive model. 1. (shrink)

Whether it seems that you know something depends in part upon practical factors. When the stakes are low, it can seem to you that you know that p, but when the stakes go up it'll seem to you that you don't. The apparent sensitivity of knowledge to stakes presents a serious challenge to epistemologists who endorse a stable semantics for knowledge attributions and reject the idea that whether you know something depends on how much is at stake. After arguing that (...) previous attempts to meet this challenge fall short, I offer a new solution: the unassertability account. The account starts with the observation that high stakes subjects aren't in an epistemic position to assert. We generally presuppose that knowing is sufficient for epistemically proper assertion, but this presupposition only stands up to scrutiny if we draw a distinction between two notions of epistemic propriety, and we shouldn't expect ordinary speakers to draw it. A subject in a high stakes situation who fails to draw the distinction will be led by the sufficiency claim to treat anything she isn't in a position to assert as something she isn't in a position to know. The sensitivity of epistemically proper assertion to practical factors explains the merely apparent sensitivity of knowledge to stakes. (shrink)

How to be trustworthy, by HawleyKatherine. Oxford: Oxford University Press, 2019. Pp. 176.

According to the widely endorsed Knowledge Account of Assertion, the epistemic requirements on assertion are captured by the Knowledge Norm of Assertion, which requires speakers only to assert what they know. This paper proposes that in addition to the Knowledge Norm there is also an Epistemic Propositional Certainty Norm of Assertion, which enjoins speakers only to assert p if they believe that p on the basis of evidence which makes p an epistemic propositional certainty. The paper explains how this propositional (...) certainty norm accounts for a range of data related to the practice of assertion and defends the norm against general objections to certainty norms of assertion put forward by Duncan Pritchard, John Turri, and Timothy Williamson, by drawing on linguistic theories about epistemic modals and gradable predicate semantics. Together these considerations show that the prospects of a certainty account of assertion are much more promising than is usually assumed. (shrink)

Safety is a notion familiar to epistemologists principally because of the way in which it has been used in the attempt to cast light on the nature of knowledge. In particular, some have argued that an important constraint on knowledge is that one knows p only if one believes p safely. In this paper, I use safety for a different purpose: to cast light on the nature of assertion. I introduce what I call the safety account of assertion, according to (...) which one asserts p properly only if one asserts p safely. The central idea is that an assertion’s propriety depends on whether one could easily have asserted falsely in a similar case. I argue that the safety account is well motivated, since it neatly explains our intuitions about a wide range of assertions of different kinds. Of particular interest is the fact that the account explains our intuitions about several kinds of assertions which appear to raise problems for well-known rival accounts. (shrink)

It is often thought that the test for whether an indicative conditional is assertible is to first suppose the antecedent and then check to see if the consequent is probable on that supposition. Call this procedure the “Ramsey Test”. Some influential accounts of indicative conditionals hold that the Ramsey Test works because indicative conditionals are used to express a high credence in the consequent conditional on the antecedent. In this paper I will argue that a different expressivist account, one inspired (...) by Brandom can handle a wider range of phenomena. In particular, it does a better job explaining how conditionals function in modus tollens arguments. I will end by discussing how the account proposed here goes beyond Brandom’s own work on logic and hermeneutics. Of particular importance is the role played by a conversational common ground, distinct from the commitments of the interpreter and interpreted. (shrink)

In this paper I draw attention to a number of problems that afflict norm accounts of assertion, i.e. accounts that explain what assertion is, and typically how speakers understand what assertion is, by appeal to a norm of assertion. I argue that the disagreements in the literature over norm selection undermines such an account of understanding. I also argue that the treatment of intuitions as evidence in the literature undermines much of the connection to empirical evidence. I further argue that (...) appeals made to conversational patterns do not require the existence of any norms at all. (shrink)

This essay uses a puzzle about assertion and time to explore the pragmatics, semantics, and epistemology of future discourse. The puzzle concerns cases in which a subject is in a position to say, at an initial time t, that it will be that ϕ, but is not in a position to say, at a later time t′, that it is or was that ϕ, despite not losing or gaining any relevant evidence between t and t′. We consider a number of (...) approaches to the puzzle and defend the view that subjects in these cases lose knowledge simply by moving through time. (shrink)

According to assurance views of testimonial justification, in virtue of the act of testifying a speaker provides an assurance of the truth of what she asserts to the addressee. This assurance provides a special justificatory force and a distinctive normative status to the addressee. It is thought to explain certain asymmetries between addressees and other unintended hearers (bystanders and eavesdroppers), such as the phenomenon that the addressee has a right to blame the speaker for conveying a falsehood but unintended hearers (...) do not, and the phenomenon that the addressee may deflect challenges to his testimonial belief to the speaker but unintended hearers may not. Here I argue that we can do a better job explaining the normative statuses associated with testimony by reference to epistemic norms of assertion and privacy norms. Following Sanford Goldberg, I argue that epistemic norms of assertion, according to which sincere assertion is appropriate only when the asserter possesses certain epistemic goods, can be ‘put to work’ to explain the normative statuses associated with testimony. When these norms are violated, they give hearers the right to blame the speaker, and they also explain why the speaker takes responsibility for the justification of the statement asserted. Norms of privacy, on the other hand, directly exclude eavesdroppers and bystanders from an informational exchange, implying that they have no standing to do many of the things, such as issue challenges or questions to the speaker, that would be normal for conversational participants. This explains asymmetries of normative status associated with testimony in a way logically independent of speaker assurance. (shrink)

According to a widely held view of assertion and belief, they are each governed by a tacitly acknowledged epistemic norm, and the norm on assertion and norm on belief are so related that believing p is epistemically permissible only if asserting it is. I call it the Same Norm View. A very common type of utterance raises a puzzle for this view, viz. utterances in which we say ‘I believe p' to convey somehow guarded affirmation of the proposition that p. (...) For example, one might respond to a query for directions to the station by saying ‘I believe it is down the first street on your left.' Often, when we reply in this way, it would have been pragmatically preferable simply to assert that p, had we been epistemically warranted in doing so. One's guarded reply thus suggests one is not so warranted. Nevertheless, if one believes what one, at face value, says one believes, one believes p. Contrary to what might seem to be suggested by the Same Norm View, one does not seem to portray oneself as irrational or epistemically beyond the pale in replying in this way. The paper develops this puzzle in detail, and examines a variety of options for a resolving it consistently with the Same Norm view. The most promising of these options, I argue, is to see ‘I believe' guarded affirmations as a form merely approximately correct speech. They would, though, be a form of such speech that interestingly differs from paradigm cases of loose use or conventional hyperbole in that speakers would be comparatively unaware of engaging in approximation. I conclude ‘I believe’—guarded affirmations either show the Same Norm View to be false or must be recognised as such an interestingly distinctive form of merely approximately correct speech.

G. E. Moore famously pointed out that all sincere assertions of the form ‘p, but I don’t believe that p’ are inherently absurd. John Turri strongly disagrees with the consensus evaluation of such assertions as inherently absurd and offers a counterexample according to which it is possible to say ‘Eliminativism is true, but of course I don’t believe it’s true’ sincerely and without any absurdity. I argue in this paper that Turri’s attempt misses the point entirely, for the most natural (...) interpretations of his counterexample are either absurd or do not represent genuinely Moorean assertions. The critical analysis of Turri’s counterexample will enable me to reach the general conclusion that precludes the possibility of omissive Moorean assertions that are inherently non-absurd, at least if we hold that our assertions ought to have some normative function.

An assertion is existentially known if and only if: (i) the speaker knows that the sentence she uses to make the assertion expresses a true proposition; (ii) she makes the assertion based on that knowledge; and (iii) she does not believe, have justification for, or know the proposition asserted. Accordingly, if existentially known assertions could be made correctly—as argued by Charlie Pelling in his ‘Assertion and the Provision of Knowledge’—this would show that the norm of assertion cannot be the speaker's (...) belief in, justification for or knowledge of the proposition. In this paper, I try to show that Pelling's argument is inconclusive, as it rests on two assumptions which can be resisted. In turn, I offer a pair of alternative strategies to explain how we can deal with existentially known assertions under the assumption that the speaker's knowledge is the norm of assertion. (shrink)

In the norms of assertion literature there has been continued focus on a wide range of odd-sounding assertions that have been collected under the umbrella of Moore’s Paradox. Our aim in these brief remarks is not to attempt to settle the question of what makes an utterance Moorean decisively, but rather to present some new data bearing on it, and to argue that this new data is best explained by a new account of Moorean absurdity.

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».

The Knowledge Account of Assertion (KAA) says that knowledge is the norm of assertion: you may assert a proposition only if you know that it’s true. The primary support for KAA is an explanatory inference from a broad range of linguistic data. The more data that KAA well explains, the stronger the case for it, and the more difficult it is for the competition to keep pace. In this paper we critically assess a purported new linguistic datum, which, it has (...) been argued, KAA well explains. We argue that KAA does not well explain it. (shrink)

It is often argued that the general propriety of challenging an assertion with ‘How do you know?’ counts as evidence for the Knowledge Norm of Assertion (KNA). Part of the argument is that this challenge seems to directly challenge whether a speaker knows what she asserts. In this article I argue for a re-interpretation of the data, the upshot of which is that we need not interpret ‘How do you know?’ as directly challenging a speaker's knowledge; instead, it's better understood (...) as challenging a speaker's reasons. Consequently, I argue that reasons-based norms can equally well explain this data. (shrink)

If we hold that perceiving is sufficient for knowing, we can raise a powerful objection to dreaming skepticism: Skeptics assume the implausible KK-principle, because they hold that if we don’t know whether we are dreaming or perceiving p, we don’t know whether p. The rejection of the KK-principle thus suggests an anti-skeptical strategy: We can sacrifice some of our self-knowledge—our second-order knowledge—and thereby save our knowledge of the external world. I call this strategy the Self-Knowledge Gambit. I argue that the (...) Self-Knowledge Gambit is not satisfactory, because the dreaming skeptic can avail herself of a normative counterpart to the KK-principle: When we lack second-order knowledge, we should suspend our first-order beliefs and thereby give up any first-order knowledge we might have had. The skeptical challenge is essentially a normative challenge, and one can raise it even if one rejects the KK-Principle. (shrink)

According to an influential hypothesis, the speech act of assertion is subject to a single 'constitutive' rule, that takes the form: "One must: assert that p only if p has C". Scholars working on assertion interpret the assumption that this rule is 'constitutive' in different ways. This disagreement, often unacknowledged, threatens the foundations of the philosophical debate on assertion. This paper reviews different interpretations of the claim that assertion is governed by a constitutive rule. It argues that once we understand (...) the full import of assuming that assertion is governed by a constitutive rule, it becomes clear that some fundamental assumptions of the current debate are mistaken, and others unwarranted. (shrink)

There is a fundamental disagreement about which norm regulates assertion. Proponents of factive accounts argue that only true propositions are assertable, whereas proponents of non-factive accounts insist that at least some false propositions are. Puzzlingly, both views are supported by equally plausible (but apparently incompatible) linguistic data. This paper delineates an alternative solution: to understand truth as the aim of assertion, and pair this view with a non-factive rule. The resulting account is able to explain all the relevant linguistic data, (...) and finds independent support from general considerations about the differences between rules and aims. (shrink)

Assertions are our standard communicative tool for sharing and acquiring information. Recent empirical studies seemingly provide converging evidence that assertions are subject to a factive norm: you are entitled to assert a proposition p only if p is true. All these studies, however, assume that we can treat participants' judgments about what an agent 'should say' as evidence of their intuitions about assertability. This paper argues that this assumption is incorrect, so that the conclusions drawn in these studies are unwarranted. (...) It shows that most people do not interpret statements about what an agent 'should say' as statements about assertability, but rather as statements about what is in the agent's interest to do. It identifies some effective measures to force the intended reading of statements about what an agent 'should say', and shows that when these measures are implemented, people's judgments consistently and overwhelmingly align with non-factive accounts of assertion.

Recent work has argued that belief is weak: the level of rational credence required for belief is relatively low. That literature has contrasted belief with assertion, arguing that the latter requires an epistemic state much stronger than (weak) belief---perhaps knowledge or even certainty. We argue that this is wrong: assertion is just as weak as belief. We first present a variety of new arguments for this, and then show that the standard arguments for stronger norms are not convincing. Finally, we (...) sketch an alternative picture on which the fundamental norm of assertion is to say what you believe, but both belief and assertion are weak. To help make sense of this, we propose that both belief and assertion involve navigating a tradeoff between accuracy and informativity, and so it can makes sense to believe/say something you only have weak evidence for, if it is informative enough.

Do we insult, offend or slight a speaker when we refuse her testimony? Do we compliment, commend or extol a speaker when we accept her testimony? I argue that the answer to both of these questions is “yes”, but only in some instances, since these respective insults and compliments track the reasons a hearer has for rejecting or accepting testimony. When disbelieving a speaker, a hearer may insult her because she judges the speaker to be either incompetent as a knower (...) or insincere as a teller. However, there are many instances where we reject testimony without making this negative evaluation of the speaker, and as such, without paying her an insult. Testimonial compliments are fewer in number, and are not constitutive of “everyday” testimonial exchanges, since, speakers who are competent as knowers and sincere as tellers are merely behaving correctly in accordance with the norms of testifying. Nevertheless, deferring to an authority on belief can be complimentary to that speaker if by doing so we judge her to have some mastery in a particular domain. Testimonial insults and compliments have important moral implications, particularly with regard to epistemic injustice and therapeutic trust. (shrink)

Analytic epistemologists agree that, whatever else is true of epistemic justification, it is distinct from knowledge. However, if recent work by Jonathan Sutton is correct, this view is deeply mistaken, for according to Sutton justification is knowledge. That is, a subject is justified in believing that p iff he knows that p. Sutton further claims that there is no concept of epistemic justification distinct from knowledge. Since knowledge is factive, a consequence of Sutton’s view is that thereare no false justified (...) beliefs. Following Sutton, I will begin by outlining kinds of beliefs that do not constitute knowledge but that seem to be justified. I will then be in a position to critically evaluate Sutton’s arguments for his position that justification is knowledge, concluding that he fails to establish his bold thesis. In the course of so doing, I will defend the following rule of assertion: (The JBK-rule) One must: assert p only if one has justification to believe that one knows that p. (shrink)

I argue that knowledge can be seen as a quality standard that governs our sharing and storing of information. This standard satisfies certain functional needs, namely it allows us to share and store trustworthy information more easily. I argue that this makes knowledge a social kind, similar in important ways to other social kinds like money. This provides us with a way of talking about knowledge without limiting ourselves to the concept of knowledge. I also outline three ways in which (...) this view of knowledge can shed light on familiar epistemological problems: it can explain why knowledge is the norm of assertion, it can help us carve out the harm associated with testimonial injustice, and it can provide us with a clear analysis of the dangers associated with spreading misinformation. (shrink)

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.

A standard objection to the suggestion that the fundamental norm of assertion is the truth norm (i.e., one must not assert p unless p) is that this norm cannot explain why warrant requires knowledge-level evidence. In a recent paper, Whiting has defended the truth-first approach to the norms of assertion by appeal to a distinction between the warrant there is to assert and the warrant one has to assert. I shall argue that this latest defensive strategy is unsuccessful.

This paper looks at whether it is possible to unify the requirements of rationality with the demands of normative reasons. It might seem impossible to do because one depends upon the agent’s perspective and the other upon features of the situation. Enter Reasons Perspectivism. Reasons perspectivists think they can show that rationality does consist in responding correctly to reasons by placing epistemic constraints on these reasons. They think that if normative reasons are subject to the right epistemic constraints, rational requirements (...) will correspond to the demands generated by normative reasons. While this proposal is prima facie plausible, it cannot ultimately unify reasons and rationality. There is no epistemic constraint that can do what reasons perspectivists would need it to do. Some constraints are too strict. The rest are too slack. This points to a general problem with the reasons-first program. Once we recognize that the agent’s epistemic position helps determine what she should do, we have to reject the idea that the features of the agent’s situation can help determine what we should do. Either rationality crowds out reasons and their demands or the reasons will make unreasonable demands. (shrink)

According to the Interpersonal View of Testimony, testimonial justification is non-evidential in nature. I begin by arguing that the IVT has the following problem: If the IVT is true, then young children and people with autism cannot participate in testimonial exchanges; but young children and people with autism can participate in testimonial exchanges; thus, the IVT should be rejected on the grounds that it has over-cognized what it takes to give and receive testimony. Afterwards, I consider what I take to (...) be the two best motivations for the IVT and argue that they both fail. The overarching lesson, then, is that the IVT is unmotivated and false; we should think of testimonial justification as being evidential in nature. (shrink)

One response to the preface paradox—the paradox that arises when each claim in a book is justified for the author and yet in the preface the author avers that errors remain—counsels against the preface belief. It is this line of thought that poses a problem for any view that places a high value on intellectual humility. If we become suspicious of preface beliefs, it will be a challenge to explain how expressions of fallibility and intellectual humility are appropriate, whether voiced (...) verbally or encoded mentally. Moreover, banning expressions of intellectual humility is especially disturbing in our context, for such a preface claim is just the sort of expression of intellectual humility that is supposed to provide a barrier to the costly damage that can be done by zealous faith found in various forms of fundamentalism. The goal is thus to find a way to express humility without engendering paradox. (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 this paper, we develop a general normative framework for criticisability, blamelessness and blameworthiness in action. We then turn to the debate on norms of assertion. We show that an application of this framework enables champions of the so-called knowledge rule of assertion to offer a theoretically motivated response to a number of putative counterexamples in terms of blamelessness. Finally, we argue that, on closer inspection, the putative counterexamples serve to confirm the knowledge rule and disconfirm rival views.

Suppose you assert a proposition p that you falsely believe to be false with the intention to deceive your audience. The standard view has it that you lied. This paper argues against orthodoxy: deceptive lying requires that p be in actual fact false, in addition to your intention to deceive by means of untruthfully asserting that p. We proceed as follows. First, an argument is developed for such falsity condition as the non-psychological component of lying. The problem with the standard (...) view, we profess, is exactly that lying is a purely psychological relation between disbelief, assertion, and intention. Then, by scrutinising familiar cases, we revisit the alleged intuitive support for the existence of true lies. It turns out these intuitions can be explained away once we reflect on the characteristic deceptive hallmarks that are associated with the distinction between lying and botched attempts at lying. Finally, we examine the morality of lying in the light of said falsity condition. The resultant view emphasises our moral sensitivity to the practical consequences of acts of lying, while still accommodating those moral considerations that pertain exclusively to the psychological components of lying.

I argue that the debates over which norm constitutes assertion can be abandoned by challenging the three main motivations for a constitutive norm. The first motivation is the alleged analogy between language and games. The second motivation is the intuition that some assertions are worthy of criticism. The third is the discursive responsibilities incurred by asserting. I demonstrate that none of these offer good reasons to believe in a constitutive norm of assertion, as such a norm is understood in the (...) literature. Others who have made similar arguments conclude that assertion does not exist at all—that there is no such thing as assertion. I disagree: we do not have to relinquish the category of assertion just because it is not normatively constituted. There are alternative ways to understand and individuate assertion that do not rely on a constitutive norm. (shrink)

This paper addresses the question whether future contingents are knowable, that is, whether one can know that things will go a certain way even though it is possible that things will not go that way. First I will consider a long-established view that implies a negative answer, and draw attention to some endemic problems that affect its credibility. Then I will sketch an alternative line of thought that prompts a positive answer: future contingents are knowable, although our epistemic access of (...) them is limited in some important respects. (shrink)

This paper articulates in formal terms a crucial distinction concerning future contingents, the distinction between what is true about the future and what is reasonable to believe about the future. Its key idea is that the branching structures that have been used so far to model truth can be employed to define an epistemic property, credibility, which we take to be closely related to knowledge and assertibility, and which is ultimately reducible to probability. As a result, two kinds of claims (...) about future contingents—one concerning truth, the other concerning credibility—can be smoothly handled within a single semantic framework. (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)

When are you in a position to rely on p in practical reasoning? Existing accounts say that you must know that p, or be in a position to know that p, or be justified in believing that p, or be in a position to justifiably believe it, and so on. This paper argues that all of these proposals face important problems, which I call the Problems of Negative Bootstrapping and of Level Confusions. I offer a diagnosis of these problems, and (...) I argue that an adequate epistemic norm must be transparent in the following sense: According to the correct epistemic norm, a consideration counts in favor of (or against) relying on p in practical reasoning iff, and to the extent that, this consideration also counts in favor of (or against) p being true. I introduce a candidate epistemic norm that satisfies this condition. According to this norm, one should rely on p in practical reasoning only if it must be that p. If we adopt a non-factualist account of “must”, this amounts to a novel and attractive proposal, a proposal that satisfies the transparency condition. (shrink)

One of the central arguments for the knowledge norm of assertion appeals to the fact that it is typically legitimate to respond to an assertion with “How do you know?”, intended as a challenge to the assertion. The legitimacy of the challenge is taken as evidence in favor of the idea that permissible assertion requires knowledge. In this paper, I argue that if the legitimacy of “How do you know?” challenges supports a knowledge norm for assertion, it also supports the (...) controversial KK thesis. I further argue that data from assertion prompts likewise supports KK. This is an unwelcome consequence for many proponents of the knowledge norm of assertion who reject KK. At the same time, it constitutes new evidence from conversational patterns in favor of the KK thesis. (shrink)

In mathematics, any form of probabilistic proof obtained through the application of a probabilistic method is not considered as a legitimate way of gaining mathematical knowledge. In a series of papers, Don Fallis has defended the thesis that there are no epistemic reasons justifying mathematicians’ rejection of probabilistic proofs. This paper identifies such an epistemic reason. More specifically, it is argued here that if one adopts a conception of mathematical knowledge in which an epistemic subject can know a mathematical proposition (...) based solely on a probabilistic proof, one is then forced to admit that such an epistemic subject can know several lottery propositions based solely on probabilistic evidence. Insofar as knowledge of lottery propositions on the basis of probabilistic evidence alone is denied by the vast majority of epistemologists, it is concluded that this constitutes an epistemic reason for rejecting probabilistic proofs as a means of acquiring mathematical knowledge.

There are norms on action and norms on assertion. That is, there are things we should and shouldn't do, and things we should and shouldn't say. How do these two kinds of norm relate? Are norms on assertion reducible to norms on action? Many philosophers think they are not. These philosophers claim there is a sui generis norm specific to assertion, a norm which is also often claimed to be constitutive of assertion. Both claims, I argue, should be rejected. The (...) phenomenon claimed to support them – the intuitive wrongness of certain assertions – does not in fact support them. Because assertion is an action, the wrongness of assertions can be explained purely by norms on action. And the specifically epistemic wrongness an assertion norm is typically supposed to explain can be explained by an uncontroversial norm on action: one shouldn't act on epistemically faulty beliefs. No additional sui generis norm on assertion is needed. (shrink)

Knowledge norms of action are sometimes said to be motivated by the fact that they align with natural assessments of action in ordinary language. Competent and rational speakers normally use ‘knowledge’ and its cognates when they assess action. In contrast, competing accounts in terms of evidence, warrant or reliability do not straightforwardly align with ordinary language assessments of action. In response to this line of reasoning, I argue that a warrant account of action may explain the prominence of ‘knowledge’ in (...) epistemic assessments better than the knowledge account. If this explanation is successful, it undermines a central rationale for the ‘knowledge first’ program in epistemology. Moreover, the explanation provides an insight into the social functions of knowledge ascriptions as well as a methodological lesson about the relationship between folk epistemology and epistemological theorizing.
