This paper extends several themes from recent work on norms of assertion. It does as much by applying those themes to the speech act of asking. In particular, it argues for the view that there is a species of asking which is governed by a certain norm, a norm to the effect that one should ask a question only if one doesn’t know its answer.

Surprisingly little has been written about hedged assertion. Linguists often focus on semantic or syntactic theorizing about, for example, grammatical evidentials or epistemic modals, but pay far less attention to what hedging does at the level of action. By contrast, philosophers have focused extensively on normative issues regarding what epistemic position is required for proper assertion, yet they have almost exclusively considered unqualified declaratives. This essay considers the linguistic and normative issues side-by-side. We aim to bring some order and clarity (...) to thinking about hedging, so as to illuminate aspects of interest to both linguists and philosophers. In particular, we consider three broad questions. 1) The structural question: when one hedges, what is the speaker’s commitment weakened from? 2) The functional question: what is the best way to understand how a hedge weakens? And 3) the taxonomic question: are hedged assertions genuine assertions, another speech act, or what? (shrink)

It is raining but you don’t believe that it is raining. Imagine silently accepting this claim. Then you believe both that it is raining and that you don’t believe that it is raining. This would be an ‘absurd’ thing to believe,yet what you believe might be true. Itmight be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to believe something about yourself that might be (...) true of you? This is Moore’s paradox as it occurs in thought. Solving the paradox consists in explaining why such beliefs are absurd. I give a survey of some of the main explanations. I largely deal with explanations of the absurdity of ‘omissive’ beliefs with contents of the form p & I don’t believe that p and of ‘commissive beliefs’ with contents of the form p & I believe that not-p as well as beliefs with contents of the form p & I don’t know that p.

It is raining but you don’t believe that it is raining. Imagine accepting this claim. Then you are committed to saying ‘It is raining but I don’t believe that it is raining’. This would be an ‘absurd’ thing to claim or assert, yet what you say might be true. It might be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to assert something about yourself (...) that might be true of you? This is Moore’s paradox as it occurs in speech. What is the source of the absurdity? And why does it strike us that a contradiction is somehow at work when there is no contradiction in the content of what is asserted? In Section 2, I describe Moore’s formulation of the paradox and evaluate his own solutions. In Section 3, I discuss Wittgenstein’s inf luence in solving the paradox. In Section 4, I discuss Shoemaker’s priority thesis that once the absurdity in belief has been explained, then this will translate into an explanation of the absurdity in assertion. In Section 5, I discuss work on omissive and commissive Moore-paradoxical assertions, i.e. those of the forms p & I don’t believe that p and p & I believe that not-p. In Section 6, I discuss work on assertions of the form p & I don’t know that p. (shrink)

ABSTRACT Timothy Williamson offers the ordinary practice, the lottery and the Moorean argument for the ‘knowledge account’ that assertion is the only speech-act that is governed by the single rule that one must know its content. I show that these fail to support it and that the emptiness of the knowledge account renders mysterious why breaking the knowledge rule should be a source of criticism. I argue that focussing exclusively on the sincerity of the speech-act of letting one know engenders (...) a category mistake about the nature of constraints on assertion. After giving an analysis of assertion I propose that the norm of a type of assertion is the epistemic state one needs for one’s speech-act to succeed in being an assertion of that type and that the epistemic state in question is determined by the point of the type of assertion. One is practically irrational in violating the norm. (shrink)

The view that truth is the norm of assertion has fallen out of fashion. The recent trend has been to think that knowledge is the norm of assertion. Objections to the knowledge view proceed almost exclusively by appeal to alleged counterexamples. While it no doubt has a role to play, such a strategy relies on intuitions concerning hypothetical cases, intuitions which might not be shared and which might shift depending on how the relevant cases are fleshed out. In this paper, (...) I reject the knowledge view on principled grounds. More specifically, by appeal to a principle which is motivated independently of the debate over the norms of assertion and which is already accepted by many proponents of the knowledge view, I show the knowledge view to be false while simultaneously accounting for why it might seem to be true. In doing so, I provide a novel defence of the unfashionable truth view. (shrink)

It is widely held that assertions are partially governed by an epistemic norm. But what is the epistemic condition set out in the norm? Is it knowledge, truth, belief, or something else? In this paper, I defend a view similar to that of Stanley (2008), according to which the relevant epistemic condition is epistemic certainty, where epistemic certainty (but not knowledge) is context-sensitive. I start by distinguishing epistemic certainty, subjective certainty, and knowledge. Then, I explain why it's much more plausible (...) to think that "certain", rather than "know", is context-sensitive. After that, I respond to an important worry raised by Pritchard, according to which the proposed view is too strong to accommodate our current practice of assertion. I then show that the main linguistic and conversational data advanced in the recent literature in favour of the knowledge condition are best explained by the certainty view. Finally, I offer two principled considerations: the certainty view is the only one compatible with three independently plausible claims and it fits very well with the common thought that knowledge does not entail certainty.

Speakers offer testimony. They also hedge. This essay offers an account of how hedging makes a difference to testimony. Two components of testimony are considered: how testimony warrants a hearer's attitude, and how testimony changes a speaker's responsibilities. Starting with a norm-based approach to testimony where hearer's beliefs are prima facie warranted because of social norms and speakers acquire responsibility from these same norms, I argue that hedging alters both components simultaneously. It changes which attitudes a hearer is prima facie (...) warranted in forming in response to testimony, and reduces how much responsibility a speaker undertakes in testifying. A consequence of this account is that speakers who hedge for strategic purposes deprive their hearers of warrant for stronger doxastic attitudes. (shrink)

Assertion is widely regarded as an act associated with an epistemic position. To assert is to represent oneself as occupying this position and/or to be required to occupy this position. Within this approach, the most common view is that assertion is strong: the associated position is knowledge or certainty. But recent challenges to this common view present new data that are argued to be better explained by assertion being weak. Old data widely taken to support assertion being strong has also (...) been challenged. This paper examines such challenges and finds them wanting. Far from diminishing the case for strong assertion, carefully considering new and old data reveals that assertion is as strong as ever. (shrink)

I report two experiments studying the relationship among explicit judgments about what people see, know, and should assert. When an object of interest was surrounded by visibly similar items, it diminished people’s willingness to judge that an agent sees, knows, and should tell others that it is present. This supports the claim, made by many philosophers, that inhabiting a misleading environment intuitively decreases our willingness to attribute perception and knowledge. However, contrary to stronger claims made by some philosophers, inhabiting a (...) misleading environment does not lead to the opposite pattern whereby people deny perception and knowledge. Causal modeling suggests a specific psychological model of how explicit judgments about perception, knowledge, and assertability are made: knowledge attributions cause perception attributions, which in turn cause assertability attributions. These findings advance understanding of how these three important judgments are made, provide new evidence that knowledge is the norm of assertion, and highlight some important subtleties in folk epistemology. (shrink)

I propose and defend the hypothesis that understanding is the norm of explanation. On this proposal, an explanation should express understanding. I call this the understanding account of explanation. The understanding account is supported by social and introspective observations. It is also supported by the relationship between knowledge and understanding, on the one hand, and assertion and explanation, on the other.

Assertion is fundamental to our lives as social and cognitive beings. Philosophers have recently built an impressive case that the norm of assertion is factive. That is, you should make an assertion only if it is true. Thus far the case for a factive norm of assertion been based on observational data. This paper adds experimental evidence in favor of a factive norm from six studies. In these studies, an assertion’s truth value dramatically affects whether people think it should be (...) made. Whereas nearly everyone agreed that a true assertion supported by good evidence should be made, most people judged that a false assertion supported by good evidence should not be made. The studies also suggest that people are consciously aware of criteria that guide their evaluation of assertions. Evidence is also presented that some intuitive support for a non-factive norm of assertion comes from a surprising tendency people have to misdescribe cases of blameless rule-breaking as cases where no rule is broken. (shrink)

Recent work in philosophy and cognitive science shows that knowledge is the norm of our social practice of assertion, in the sense that an assertion should express knowledge. But why should an assertion express knowledge? I hypothesize that an assertion should express knowledge because the point of assertion is to transmit knowledge. I present evidence supporting this hypothesis.

I accomplish two things in this paper. First I expose some important limitations of the contemporary literature on the norms of assertion and in the process illuminate a host of new directions and forms that an account of assertional norms might take. Second I leverage those insights to suggest a new account of the relationship between knowledge and assertion, which arguably outperforms the standard knowledge account.

Researchers have debated whether knowledge or certainty is a better candidate for the norm of assertion. Should you make an assertion only if you know it's true? Or should you make an assertion only if you're certain it's true? If either knowledge or certainty is a better candidate, then this will likely have detectable behavioral consequences. I report an experiment that tests for relevant behavioral consequences. The results support the view that assertability is more closely linked to knowledge than to (...) certainty. In multiple scenarios, people were much more willing to allow assertability and certainty to come apart than to allow assertability and knowledge to come apart. (shrink)

Assertion is fundamental to our lives as social and cognitive beings. By asserting we share knowledge, coordinate behavior, and advance collective inquiry. Accordingly, assertion is of considerable interest to cognitive scientists, social scientists, and philosophers. This paper advances our understanding of the norm of assertion. Prior evidence suggests that knowledge is the norm of assertion, a view known as “the knowledge account.” In its strongest form, the knowledge account says that knowledge is both necessary and sufficient for assertability: you should (...) make an assertion if and only if you know that it is true. The knowledge account has been rejected on the grounds that it conflicts with our ordinary practice of evaluating assertions. This paper reports four experiments that address an important objection of this sort, which focuses on a class of examples known as “Gettier cases.” The results undermine the objection and, in the process, provide further evidence for the knowledge account. The findings also teach some important general lessons about intuitional methodology and the curation of genres of thought experiment. (shrink)

Can judging that an agent blamelessly broke a rule lead us to claim, paradoxically, that no rule was broken at all? Surprisingly, it can. Across seven experiments, we document and explain the phenomenon of excuse validation. We found when an agent blamelessly breaks a rule, it significantly distorts people’s description of the agent’s conduct. Roughly half of people deny that a rule was broken. The results suggest that people engage in excuse validation in order to avoid indirectly blaming others for (...) blameless transgressions. Excuse validation has implications for recent debates in normative ethics, epistemology and the philosophy of language. These debates have featured thought experiments perfectly designed to trigger excuse validation, inhibiting progress in these areas. (shrink)

Communication is essential to human society, and assertion is central to communication. This article reviews evidence from life science, cognitive science, and philosophy relevant to understanding how our social practice of assertion is structured and sustained. The principal conclusion supported by this body of evidence is that knowledge is a central norm of assertion—that is, according to the rules of the practice, assertions should express knowledge.

According to factive accounts of the norm of belief and decision-making, you should not believe or base decisions on a falsehood. Even when the evidence misleadingly suggests that a false proposition is true, you should not believe it or base decisions on it. Critics claim that factive accounts are counterintuitive and badly mischaracterize our ordinary practice of evaluating beliefs and decisions. This paper reports four experiments that rigorously test the critic’s accusations and the viability of factive accounts. The results undermine (...) the accusations and provide the best evidence yet of factive norms of belief and decision-making. The results also help discriminate between two leading candidates for a factive norm: truth and knowledge. Knowledge is the superior candidate. (shrink)

In this paper I will compare two competing accounts of assertion: the knowledge account and the justified belief account. When it comes to the evidence that is typically used to assess accounts of assertion – including the evidence from lottery propositions, the evidence from Moore’s paradoxical propositions and the evidence from conversational patterns – I will argue that the justified belief account has at least as much explanatory power as its rival. I will argue, finally, that a close look at (...) the ways in which assertions can be challenged and retracted reveals a certain advantage for the justified belief account. The paper will touch upon a number of further topics along the way, including the logical interaction between knowledge and justified belief, the nature of defeat, and the hypothesis that knowledge and justified belief are normatively coincident goals.

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)

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)

If one’s solution to the free will problem is in terms of real causal powers of agents then one ought to be an incompatibilist. Some premises are contentious but the following new argument for incompatibilism is advanced: 1. If causal determinism is true, all events are necessitated2. If all events are necessitated, then there are no powers3. Free will consists in the exercise of an agent’s powersTherefore, if causal determinism is true, there is no free will; which is to say (...) that free will is incompatible with determinism, so compatibilism is false. (shrink)

One of the main arguments intended to show that content externalism undermines the privileged access thesis is the ‘slow switching argument’, originally proposed by Boghossian. In this argument, it is supposed that a subject is unknowingly switched back and forth between Earth and Twin Earth: then it is claimed that, given externalism, when the subject is on Earth thinking that water is wet, he cannot know the content of his thought a priori, for he cannot, by mere reflection, rule out (...) the relevant alternative hypothesis that he is on Twin Earth thinking that twater is wet. One of the controversies surrounding this argument stems from the fact that it is not clear which epistemological principle underlies it. Here, I examine two suggestions made in the literature as to what that underlying principle might be. I argue that neither of these suggested principles is plausible, and thus that the slow switching argument never gets off the ground. (shrink)

An agent A blames B hypocritically for violating a moral norm N if and only if: A is likewise blameworthy for violating N, and A is not disposed to blame herself for violating N. Normally, an assertion involving blame is retracted following the objection that and hold. I discuss two prima facie explanations for such a withdrawal: that the objection hampers the speaker’s assertoric authority, rendering and the necessary condition to assert, and that the joint condition is, instead, merely a (...) regulative rule. Having shown that the former option is too revisory as it requires reformulation of all normative accounts of assertion on the table, and the latter false, I proceed to argue that and do not target assertions to begin with. An assertion involving blame is, instead, a clear case of a double speech act: after arguing for this claim, I proceed to show that qua assertion, the act is correct given one’s preferred normative account, whereas it is incorrect qua blaming, as in order to perform such an act, the speaker needs to satisfy the conditions and. (shrink)

Here I advance a unified account of the structure of the epistemic normativity of assertion, action, and belief. According to my Teleological Account, all of these are epistemically successful just in case they fulfill the primary aim of knowledgeability, an aim which in turn generates a host of secondary epistemic norms. The central features of the Teleological Account are these: it is compact in its reliance on a single central explanatory posit, knowledge-centered in its insistence that knowledge sets the fundamental (...) epistemic norm, and yet fiercely pluralistic in its acknowledgment of the legitimacy and value of a rich range of epistemic norms distinct from knowledge. Largely in virtue of this pluralist character, I argue, the Teleological Account is far superior to extant knowledge-centered accounts. (shrink)

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)

The target of this paper is the ‘simple’ knowledge account of assertion, according to which assertion is constituted by a single epistemic rule of the form ‘One must: assert p only if one knows p’. My aim is to argue that those who are attracted to a knowledge account of assertion should prefer what I call the ‘complex’ knowledge account, according to which assertion is constituted by a system of rules all of which are, taken together, constitutive of assertion. One (...) of those rules—which, following John Searle, I call the ‘preparatory condition’—is of the form ‘One must: assert p only if one knows p.’ All else being equal, simple accounts are preferable to complex accounts. I argue in this paper that all else isn't equal. While the simple knowledge account provides an elegant explanation of certain data, it is hard to see how to integrate the simple knowledge account into a more general theory of illocutionary acts. Because the complex knowledge account avoids this objection whil.. (shrink)

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. (shrink)

The present paper argues that there is a knowledge norm for conversational implicature: one may conversationally implicate p only if one knows p. Linguistic data about the cancellation behavior of implicatures and the ways they are challenged and criticized by speakers is presented to support the thesis. The knowledge norm for implicature is then used to present a new consideration in favor of the KK thesis. It is argued that if implicature and assertion have knowledge norms, then assertion requires not (...) only knowledge but iterated knowledge: knowing that you know that you know that... you know. Such a condition on permissible assertion is argued to be plausible only if the KK thesis is true. (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 this paper I consider the prospects for an epistemic norm which relates knowledge-how to showing in a way that parallels the knowledge norm of assertion. In the first part of the paper I show that this epistemic norm can be motivated by conversational evidence, and that it fits in with a plausible picture of the function of knowledge. In the second part of the paper I present a dilemma for this norm. If we understand showing in a broad sense (...) as a general kind of skill teaching, then the norm faces counterexamples of teachers who know how to teach, but not to do. On the other hand, it we understand showing more narrowly as involving only teaching by doing the relevant activity, then the data which initially supported the norm can be explained away by more general connections between knowledge-how and intentional action.

According to the normative approach, speech acts are governed by certain norms. Interestingly, the same is true for classes of speech acts. This paper considers the normative treatment of constatives, consisting of such classes as assertives, predictives, suggestives, and more. The classical approach is to treat these classes of illocutions as species of constatives. Recently, however, Simion (Shifty Speech and Independent Thought: Epistemic Normativity in Context, Oxford University Press, 2021) has proposed that all constatives (i) are species of assertion, and (...) (ii) are governed by the knowledge norm. I defend the classical treatment of constatives and show that Simion’s conclusion is untenable. No taxonomy of speech acts can accommodate such a view. More importantly, we can test whether a particular speech act is an assertion or not. I propose five tests of assertion, the passing of which is a necessary condition for being an assertion. Some constative speech acts fail these tests. Thus, contrary to Simion, not all constatives can be regarded as species of assertion. (shrink)

In this paper I provide a new account of linguistic presuppositions, on which they are ancillary speech acts defined by constitutive norms. After providing an initial intuitive characterization of the phenomenon, I present a normative speech act account of presupposition in parallel with Williamson’s analogous account of assertion. I explain how it deals well with the problem of informative presuppositions, and how it relates to accounts for the Triggering and Projection Problems for presuppositions. I conclude with a brief discussion of (...) the consequences of the proposal for the adequacy of Williamson’s account of assertion. (shrink)

Pedagogy is a pillar of human culture and society. Telling each other information and showing each other how to do things comes naturally to us. A strong case has been made that declarative knowledge is the norm of assertion, which is our primary way of telling others information. This article presents an analogous case for the hypothesis that procedural knowledge is the norm of instructional demonstration, which is a primary way of showing others how to do things. Knowledge is the (...) norm of telling and showing. It is the prime pedagogical principle. (shrink)

We distinguish between two categories of belief—thin belief and thick belief—and provide evidence that they approximate genuinely distinct categories within folk psychology. We use the distinction to make informative predictions about how laypeople view the relationship between knowledge and belief. More specifically, we show that if the distinction is genuine, then we can make sense of otherwise extremely puzzling recent experimental findings on the entailment thesis (i.e. the widely held philosophical thesis that knowledge entails belief). We also suggest that the (...) distinction can be applied to debates in the philosophy of mind and metaethics. (shrink)

Many philosophers are building a solid case in favour of the knowledge account of assertion (KAA). According to KAA, if one asserts that P one represents oneself as knowing that P. KAA has recently received support from linguistic data about prompting challenges, parenthetical positioning and predictions. In this article, I add another argument to this rapidly growing list: an argument from what I will call ‘reinforcing parenthesis’.

Many contemporary philosophers argue that assertion is governed by an epistemic norm. In particular, many defend the knowledge account of assertion, which says that one should assert only what one knows. Here, I defend a non‐normative alternative to the knowledge account that I call the repK account of assertion. According to the repK account, assertion represents knowledge, but it is not governed by a constitutive epistemic rule. I show that the repK account offers a more straightforward interpretation of the conversational (...) patterns and intuitions that motivate the knowledge account. It does so in terms of ordinary normative principles that philosophers already accept, none of which are constitutive to assertion. I then contend that the repK account is preferable to the knowledge account because it is simpler, its implications are less contentious, and it avoids a problem for normative accounts of assertion recently raised by Peter Pagin. I also argue that the repK account offers a satisfying explanation of selfless assertion, a counterexample to the knowledge account posed by Jennifer Lackey. (shrink)

The Knowledge Norm or Knowledge Account of Assertion (KAA) has received added support recently from data on prompting assertion (Turri 2010) and from a refinement suggesting that assertions ought to express knowledge (Turri 2011). This paper adds another argument from parenthetical positioning, and then argues that KAA’s unified explanation of some of the earliest data (from Moorean conjunctions) adduced in its favor recommends KAA over its rivals.

Epistemologists focus primarily on cases of knowledge, belief, or credence where the evidence which one possesses, or on which one is relying, plays a fundamental role in the epistemic or normative status of one's doxastic state. Recent work in epistemology goes beyond the evidence one possesses to consider the relevance for such statuses of evidence which one does not possess, particularly when there is a sense in which one should have had some evidence. I focus here on Sanford Goldberg's approach (...) ("Should Have Known," Synthese, forthcoming; and "On the Epistemic Significance of Evidence You Should Have Had," Episteme 2016, this issue); but the discussion will interest anyone working on epistemic defeat.

Some philosophers oppose recent arguments for the Knowledge Norm of Assertion by claiming that assertion, being an act much like any other, will be subject to norms governing acts generally, such as those articulated by Grice for the purpose of successful, cooperative endeavours. But in fact, Grice is a traitor to their cause; or rather, they are his dissenters, not his disciples. Drawing on Grice's unpublished papers, I show that he thought of asserting as a special linguistic act in need (...) of its own norm, and he tied his maxim of Quality to knowledge. I also develop a simple Gricean-inspired argument showing that the Quality maxim is not dependent on the Cooperative Principle. If it is not thus dependent, then the Cooperative Principle cannot be the explanation of, or source of normativity for, the Quality maxim. Thus, leveraging the insights informing the maxim of Quality actually provides the resources for a distinctive positive case that knowledge is the constitutive norm of assertion. (shrink)

Expert testimony figures in recent debates over how best to understand the norm of assertion and the domain-specific epistemic expectations placed on testifiers. Cases of experts asserting with only isolated second-hand knowledge (Lackey 2011, 2013) have been used to shed light on whether knowledge is sufficient for epistemically permissible assertion. I argue that relying on such cases of expert testimony introduces several problems concerning how we understand expert knowledge, and the sharing of such knowledge through testimony. Refinements are needed to (...) clarify exactly what principles are being tested by such cases; but once refined, such cases raise more questions than they answer. (shrink)

This chapter reviews empirical research on the rules governing assertion and retraction, with a focus on the normative role of truth. It examines whether truth is required for an assertion to be considered permissible, and whether there is an expectation that speakers retract statements that turn out to be false. Contrary to factive norms (such as the influential “knowledge norm”), empirical data suggests that there is no expectation that speakers only make true assertions. Additionally, contrary to truth-relativist accounts, there is (...) no requirement for speakers to retract statements that are false at the context of assessment. We conclude by suggesting that truth still plays a crucial role in the evaluation of assertions: as a standard for evaluating their success, rather than permissibility. (shrink)

Robert Brandom’s normative-pragmatic theory is intended to represent the minimal set of practical abilities whose exhibition qualifies creatures as speaking a language. His model of a minimally discursive practice (MDP) is one in which participants, devoid of logical vocabulary, are only capable of making assertions and drawing inferences. This paper argues that Brandom’s purely assertional practices are not MDPs and that speech acts of asking questions (queries) must be included in any practice that counts as an MDP. The upshot of (...) the argument is support for the claim that the normative pragmatic analysis of assertions requires a corresponding analysis of queries and vice versa. (shrink)

According to the extended knowledge account of assertion, we should only assert and act on what we know. Call this the ‘Knowledge Norm’. Because moral and prudential rules prohibit morally and prudentially unacceptable actions and assertions, they can, familiarly, override the Knowledge Norm. This, however, raises the question of whether other epistemic norms, too, can override the Knowledge Norm. The present chapter offers an affirmative answer to this question and then argues that the Knowledge Norm is derived from a more (...) fundamental norm that demands that we do not hinder intellectual flourishing. As the fundamental epistemic norm can come into conflict with the Knowledge Norm, it is sometimes permissible to assert and act on what we don’t know. The chapter concludes with a discussion of the consequences of this insight for the extended knowledge account of assertion. (shrink)

This paper reviews recent philosophical work on assertion, with a special focus on work exploring the theme of assertion's norm. It concludes with a brief section characterizing several open questions that might profitably be explored from this perspective.

In this thesis, I propose and defend a theory according to which committing oneself to knowing the proposition expressed counts as an assertion of that proposition. A consequence of this view is the knowledge account of assertion, according to which one asserts that p correctly only if one knows that p. In support of this approach, I offer a strategy of identifying an assertion’s “normative consequences”, types of act that normally take place as a result of one’s making an assertion (...) incorrectly. I outline two such phenomena: retraction and disavowal of knowledge. In continuation, I put the theory to test and critically examine four sets of objections against it, arguing that it can convincingly defuse them. Finally, I discuss two related issues: I maintain that by performing “aesthetic assertions” one also normally performs a non-assertoric speech act of recommendation, and argue for the possibility of “non-linguistic assertions”, whose content is expressed by gestures in appropriate contexts.
