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)

I argue against Milić's (2017) proposal of analyzing “selfless assertions” (Lackey 2007) as proper, i.e., as assertions which satisfy the norm of assertion. In his view, selfless assertions are hedged assertions governed by the knowledge norm. In my critique, I show that Milić does not make a case that selfless assertions constitute such a special class of assertions. Moreover, he does not deliver a clear criterion for differentiating between flat-out assertions and hedged ones. What is more, his (...) proposal leaves some cases of selfless assertions unexplained. The outcome is that we are still left without a satisfactory account of selfless assertions as proper assertions. (shrink)

We argue that knowledge is not the norm of belief given that ‘I believe’ is used to hedge. We explore the consequences of this argument for the normative relationship between belief and assertion.

Assertion is governed by an epistemic norm requiring knowledge. This idea has been hotly debated in recent years, garnering attention in epistemology, philosophy of language, and linguistics. This chapter presents and extends the main arguments in favor of the knowledge norm, from faulty conjunctions, several conversational patterns, judgments of permission, excuse, and blame, and from showing how. (Paired with a chapter by Peter J. Graham and Nikolaj J. L. L. Pedersen, "Knowledge is Not Our Norm of Assertion.").

I explore how rational belief and rational credence relate to evidence. I begin by looking at three cases where rational belief and credence seem to respond differently to evidence: cases of naked statistical evidence, lotteries, and hedged assertions. I consider an explanation for these cases, namely, that one ought not form beliefs on the basis of statistical evidence alone, and raise worries for this view. Then, I suggest another view that explains how belief and credence relate to evidence. My (...) view focuses on the possibilities that the evidence makes salient. I argue that this makes better sense of the difference between rational credence and rational belief than other accounts. (shrink)

In this paper, we draw on Alfred Schutz’s theoretical framework to better understand how oppression is enacted through discriminatory acts. By closely examining the role of typifications and relevances in our experience of others, and by supplementing this analysis with contemporary social scientific resources, we argue that a Schutzian perspective on oppression yields important phenomenological insights. We do this in three key steps. Firstly, we contextualise Equality and the Meaning Structure of the Social World within Schutz’s broader body of work, (...) elucidating his central conditions of discrimination. Secondly, we highlight the limitations of Schutz’s account, in how it fails to capture more peripheral, subtle, and implicit oppressive practices. Finally, we introduce two underexplored insights derived from Schutz’s framework: the role of relevances in understanding the motivational underpinnings of implicit biases, and the connection between self-typification and stereotype threat. With this multidimensional approach, we hope to enhance our understanding of oppression whilst bridging gaps in Schutz’s original conceptualization. (shrink)

Over the years, phenomenology has provided illuminating descriptions of discrimination, with its mechanisms and effects being thematised at the most basic levels of embodiment, (dis)orientation, selfhood, and belonging. What remains somewhat understudied is the lived experience of the discriminator. In this paper I draw on Husserl's phenomenological account of normality to reflect on the ways in which we discriminate at the prereflective levels of perceptual experience and bodily being. By critically reflecting on the intentional structures undergirding discriminatory practices, I argue (...) that discrimination is characteristic of a naïve normalising attitude which is habitually interested in securing a familiar experience of a static normality. I first demonstrate how this attitude problematically tends to reproduce, enforce, and further sediment discriminatory and exclusionary norms. Further, I provide an internal critique which problematises discrimination—without recourse to external normative standards—on three fronts: as epistemically unproductive, experientially obscuring, and normatively non-instantiating. In discriminatory acts we see an abnormal refusal to enrich, revise, and genetically establish new normative commitments, new ways of seeing, and a new normality. (shrink)

Phenomenological discussions of sociality have long been concerned with the relations between the I, the You, and the We. Recently, dialogue between phenomenology and analytic philosophical work on collective intentionality has given rise to a corpus of literature oriented around the first-person plural 'we'. In this paper, I demonstrate how these dominant accounts of the 'we' are not exhaustive of first-person plural experiences as such. I achieve these aims by arguing for a phenomenological distinction between an experience of being part (...) of a 'we' compared to an experience of being part of an 'us'. To have a 'we-experience' there must be a plurality of (unified) subjects sharing in an experience together such that the experience has the phenomenal character of being ours. An 'us-experience', on the other hand, requires the experiential salience of an external 'Third' in a way which is constitutively significant. Drawing on Sartrean social ontology, I argue that the 'us' is distinct from the 'we' on three levels, all of which pertain to the constitutive and unifying role of the Third. I then outline two forms of us-experiences: (1) the experience of being grouped and (2) the experience of apprehending one's seriality. (shrink)

Scientific hedges are communicative devices used to qualify and weaken scientific claims. Gregor Betz has argued—unconvincingly, we think—that hedging can rescue the value-free ideal for science. Nevertheless, Betz is onto something when he suggests there are political principles that recommend scientists hedge public-facing claims. In this article, we recast this suggestion using the notion of public justification. We formulate and reject a Rawlsian argument that locates the justification for hedging in its ability to forge consensus. On our alternative proposal, hedging (...) is often justified because it renders scientific claims as publicly accessible reasons. (shrink)

What sort of epistemic positions are compatible with inquiries driven by interrogative attitudes like wonder and puzzlement? The ignorance norm provides a partial answer: interrogative attitudes directed at a particular question are never compatible with knowledge of the question’s answer. But some are tempted to think that interrogative attitudes are incompatible with weaker positions like belief as well. This paper defends that the ignorance norm is exhaustive. All epistemic positions weaker than knowledge directed at the answer to a question are (...) compatible with having an interrogative attitude towards that question. We offer two arguments for this conclusion. The first is based on considerations about the role of hedging in inquiry. The second is conditional on considerations related to the aim of inquiry as a goal-directed activity. (shrink)

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)

Epistemic terms of various syntactic categories can uniformly be used to do the same thing—to hedge. This essay clarifies hedging as a phenomenon and explains how hedging happens by advancing the positional theory. The guiding idea is that, in uttering declaratives, speakers signal what their epistemic position is towards the content put into play by the declarative. The default signal is that the speaker knows. But when an epistemic term hedges, the term overrides the default. The non-default signal sent is (...) that the speaker or someone else occupies the position indicated by the term. To make that idea precise, the positional theory treats hedging as a discourse function. Terms hedge because of how a declarative containing an epistemic term is situated within a discourse. (shrink)

In this paper, I argue that the fetishism objection to moral hedging fails. The objection rests on a reasons-responsiveness account of moral worth, according to which an action has moral worth only if the agent is responsive to moral reasons. However, by adopting a plausible theory of non-ideal moral reasons, one can endorse a reasons-responsiveness account of moral worth while maintaining that moral hedging is sometimes an appropriate response to moral uncertainty. Thus, the theory of moral worth upon which the (...) fetishism objection relies does not, in fact, support that objection. (shrink)

Semantic externalism in the style of McDowell and Evans faces a puzzle formulated by Pryor: to explain that a sentence such as 'Jack exists' is only a posteriori knowable, despite being logically entailed by the seemingly logical truth 'Jack is self-identical', and hence being itself a logical truth and therefore a priori knowable. Free logics can dissolve the puzzle. Moreover, Pryor has argued that the existentially hedged 'If Jack exists, then Jack is self-identical', when properly formalised, is a logical (...) truth in a system of neutral free logic and therefore a priori knowable, while it does not entail that Jack exists. The latter holds also for negative free logic. In response, Yeakel has argued that on any system of neutral free logic existence hedges will either entail some unwanted existence claims or they will not entail some wanted existence claims. The dilemma also holds for any non-positive free logic. It will be shown that the extension of one of the systems of neutral free logic with a truth operator escapes Yeakel's dilemma, whereas no other non-positive free logic when extended with the truth operator does the same (or it breaks quantifier exchangeability).

In proxy assertion an individual or group asserts something through a spokesperson. The chapter explains proxy assertion as resting on the assignment of a status role to a person (that of spokesperson) whose utterances acts in virtue of that role have the status function of signaling that the principal is committed in a way analogous to an individual asserting that in his own voice. The chapter briefly explains how status functions and status roles are grounded and then treats, (...) in turn, the case of a spokesperson for an individual and a group and the differences in the significance of what the spokesperson does in each case. Finally, it reviews complications introduced by spokesperson autonomy, where the spokesperson is given leave to represent her principal’s views or positions in her own words and to respond to questions on his behalf.

One is sometimes, but only sometimes, justified in pursuing a suboptimal course of action due to a concern that, in attempting the ideal course, one might fail to follow through and so make the situation even worse. This paper explains why such hedging is sometimes justified and sometimes not. -/- The explanation we offer relies on Elizabeth Anscombe’s distinction between reasons and logoi. Reasons are normative considerations that identify something good or bad that an act will secure or avoid, while (...) logoi constrain which actions one may consider at all. We argue that a careful unpacking of this distinction, in light of Anscombe’s associated notion of natural unintelligibility, explains why hedging is only sometimes justified. First, the intuitively inappropriate cases of hedging all involve treating logoi as though they had the normative bearing of reasons. Second, the action-theoretic differences between reasons and logoi ground a principled explanation of why one may hedge when considering reasons but not when considering logoi. -/- Having made this argument, we then show how our approach to hedging is superior to the two approaches recently developed by Berislav Marušić and Stephen White. First, we show that their accounts give counter-intuitive results in some cases. Second, we argue that their accounts violate a plausible principle of interpersonal parity (i.e., they sometimes allow us to consider the faults of others while precluding us from considering our own faults). Finally, we argue that our account better explains how intuitions shift as we vary the details of cases. (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)

We argue that honesty in assertion requires non-empirical knowledge that what one asserts is what one believes. Our argument proceeds from the thought that to assert honestly, one must follow and not merely conform to the norm ‘Assert that p only if you believe that p’. Furthermore, careful consideration of cases shows that the sort of doxastic self-knowledge required for following this norm cannot be acquired on the basis of observation, inference, or any other form of detection of one’s (...) own doxastic states. It is, as we put it, transparent rather than empirical self-knowledge. (shrink)

This paper offers a general model of substantive moral principles as a kind of hedged moral principles that can (but don't have to) tolerate exceptions. I argue that the kind of principles I defend provide an account of what would make an exception to them permissible. I also argue that these principles are nonetheless robustly explanatory with respect to a variety of moral facts; that they make sense of error, uncertainty, and disagreement concerning moral principles and their implications; and (...) that one can grasp these principles without having to grasp any particular list of their permissibly exceptional instances. I conclude by pointing out various advantages that this model of principles has over several of its rivals. The bottom line is that we should find nothing peculiarly odd or problematic about the idea of exception-tolerating and yet robustly explanatory moral principles. (shrink)

I argue here for a view I call epistemic separabilism , which states that there are two different ways we can be evaluated epistemically when we assert a proposition or treat a proposition as a reason for acting: one in terms of whether we have adhered to or violated the relevant epistemic norm, and another in terms of how epistemically well-positioned we are towards the fact that we have either adhered to or violated said norm. ES has been appealed to (...) most prominently in order to explain why epistemic evaluations that conflict with the knowledge norm of assertion and practical reasoning nevertheless seem correct. Opponents of such a view are committed to what I call epistemic monism , which states that there is only one way we can be properly evaluated as epistemically appropriate asserters and practical reasoners, namely in terms of whether we have adhered to or violated the relevant norm. Accepting ES over EM has two significant consequences: first, a “metaepistemological” consequence that the structure of normative epistemic evaluations parallels that found in other normative areas , and second, that the knowledge norms of assertion and practical reasoning are no worse off than any alternatives in terms of either explanatory power or simplicity. (shrink)

It is increasingly recognized that knowledge is the norm of assertion. As this view has gained popularity, it has also garnered criticism. One widely discussed criticism involves thought experiments about “selfless assertion.” Selfless assertions are said to be intuitively compelling examples where agents should assert propositions that they don’t even believe and, hence, don’t know. This result is then taken to show that knowledge is not the norm of assertion. This paper reports four experiments demonstrating that “selfless (...) assertors” are viewed as both believing and knowing the propositions they assert: this is the natural and intuitive way of interpreting the case. Thought experiments about selfless assertions do not threaten the knowledge account and they do not motivate weaker alternative accounts. The discussion also highlights a general lesson for philosophers: thought experiments intended to probe for mental state attributions should not conflict with basic principles that guide social cognition.

How should we undertand the role of norms—especially epistemic norms—governing assertive speech acts? Mitchell Green (2009) has argued that these norms play the role of handicaps in the technical sense from the animal signals literature. As handicaps, they then play a large role in explaining the reliability—and so the stability (the continued prevalence)—of assertive speech acts. But though norms of assertion conceived of as social norms do indeed play this stabilizing role, these norms are best understood as deterrents and (...) not as handicaps. This paper explains the stability problem for the maintenance of animal signals, and so human communication, for we are animals too, after all; the mechanics of the handicap principle; the role of deterrents and punishments as an alternative mechanism; and the role of social norms governing assertion for the case of human communication.

The aim of this paper is twofold: First, we present and develop a system of logic for pragmatics including the act of denial. Second, we analyse in our framework the so-called paradox of assertability. We show that it is possible to yield sentences that are not assertable. Moreover, under certain conditions, a symmetric result can be obtained: There is a specular paradox of deniability. However, this paradox is based on the problematic principle of classical denial equivalence.

I argue that the appropriateness of an assertion is sensitive to context—or, really, the “common ground”—in a way that hasn’t previously been emphasized by philosophers. This kind of context-sensitivity explains why some scientific conclusions seem to be appropriately asserted even though they are not known, believed, or justified on the available evidence. I then consider other recent attempts to account for this phenomenon and argue that if they are to be successful, they need to recognize the kind of context-sensitivity (...) that I argue for.

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)

Many philosophers, following Williamson (The Philosophical Review 105(4): 489–523, 1996), Williamson (Knowledge and its Limits, Oxford, Oxford Univer- sity Press, 2000), subscribe to the constitutive rule account of assertion (CRAA). They hold that the activity of asserting is constituted by a single constitutive rule of assertion. However, in recent work, Maitra (in: Brown & Cappelen (ed). Assertion: new philosophical essays, Oxford, Oxford University Press, 2011), Johnson (Acta Analytica 33(1): 51–67, 2018), and Kelp and Simion (Synthese 197(1): 125–137, (...) 2020a), Kelp and Simion (in: Goldberg (ed) The Oxford Handbook of Assertion, Oxford, Oxford University Press, 2020b) aim to show that, for all the most popular versions of the constitutive rule of assertion proposed in the literature, asserting is not an activity constituted by a single constitutive rule and that therefore CRAA is very likely false. To reach this conclusion, they all present a version of what can be dubbed the engagement condition objection. That is, they each propose a necessary condition on engaging in rule-constituted activities. Then they argue that, for all the most popular versions of the constitutive rule of assertion proposed in the literature, one can make assertions without satisfying this condition. In response, I present a counterexample that shows that the proposed engagement conditions lead to coun- terintuitive results, and I propose an alternative that better captures our intuitions. Then I argue that this alternative engagement condition is compatible with all the most popular versions of the constitutive rule of assertion. (shrink)

I suggest a way of extending Stalnaker’s account of assertion to allow for centered content. In formulating his account, Stalnaker takes the content of assertion to be uncentered propositions: entities that are evaluated for truth at a possible world. I argue that the content of assertion is sometimes centered: the content is evaluated for truth at something within a possible world. I consider Andy Egan’s proposal for extending Stalnaker’s account to allow for assertions with centered content. I (...) argue that Egan’s account does not succeed. Instead, I propose an account on which the contents of assertion are identified with sets of multi-centered worlds. I argue that such a view not only provides a plausible account of how assertions can have centered content, but also preserves Stalnaker’s original insight that successful assertion involves the reduction of shared possibilities.

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)

Standard objections to the notion of a hedged, or ceteris paribus, law of nature usually boil down to the claim that such laws would be either 1) irredeemably vague, 2) untestable, 3) vacuous, 4) false, or a combination thereof. Using epidemiological studies in nutrition science as an example, I show that this is not true of the hedged law-like generalizations derived from data models used to interpret large and varied sets of empirical observations. Although it may be ‘in (...) principle impossible’ to construct models that explicitly identify all potential causal interferers with the relevant generalization, the view that our failure to do so is fatal to the very notion of a cp-law is plausible only if one illicitly infers metaphysical impossibility from epistemic impossibility. I close with the suggestion that a model-theoretic approach to cp-laws poses a problem for recent attempts to formulate a Mill-Ramsey-Lewis theory of cp-laws. (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)

John N. Williams (1994) and Matthew Weiner (2005) invoke predictions in order to undermine the normative relevance of knowledge for assertions; in particular, Weiner argues, predictions are important counterexamples to the Knowledge Account of Assertion (KAA). I argue here that they are not true counterexamples at all, a point that can be agreed upon even by those who reject KAA.

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)

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)

We present an inferentialist account of the epistemic modal operator might. Our starting point is the bilateralist programme. A bilateralist explains the operator not in terms of the speech act of rejection ; we explain the operator might in terms of weak assertion, a speech act whose existence we argue for on the basis of linguistic evidence. We show that our account of might provides a solution to certain well-known puzzles about the semantics of modal vocabulary whilst retaining classical (...) logic. This demonstrates that an inferentialist approach to meaning can be successfully extended beyond the core logical constants. (shrink)

We argue against the knowledge rule of assertion, and in favour of integrating the account of assertion more tightly with our best theories of evidence and action. We think that the knowledge rule has an incredible consequence when it comes to practical deliberation, that it can be right for a person to do something that she can't properly assert she can do. We develop some vignettes that show how this is possible, and how odd this consequence is. We (...) then argue that these vignettes point towards alternate rules that tie assertion to sufficient evidence-responsiveness or to proper action. These rules have many of the virtues that are commonly claimed for the knowledge rule, but lack the knowledge rule's problematic consequences when it comes to assertions about what to do. (shrink)

[The version of this paper published by Oxford online in 2019 was not copy-edited and has some sense-obscuring typos. I have posted a corrected (but not the final published) version on this site. The version published in print in 2020 has these corrections.] Which is more fundamental, assertion or testimony? Should we understand assertion as basic, treating testimony as what you get when you add an interpersonal addressee? Or should we understand testimony as basic, treating mere assertion (...) -- assertion without testimony -- as what you get when you subtract that interpersonal relation? In this chapter, I’ll argue for the subtractive approach and for the more general thesis that its treatment of the interpersonal element in assertion makes understanding that interpersonal element the key to understanding how assertion expresses belief. My theory of belief-expression in assertion treats it as internalizing the transmission of belief in testimony. How we understand that internalizing move depends on how we conceptualize the interpersonal element in testimony. Since what I’ll call the Command Model does not give us the conceptual resources to make this move, we should adopt an alternative that I’ll call the Custodial Model, on which a testifier aims not to convince her addressee but to reason with him – to give him reasons to believe what she tells him grounded in her trustworthiness in thus attempting to influence him. The subtractive approach to assertion thus rests on a key distinction between the aims of reasoning and persuasion. (shrink)

This paper argues for a treatment of belief as essentially sensitive to certain features of context. The first part gives an argument that we must take belief to be context-sensitive in the same way that assertion is, if we are to preserve appealing principles tying belief to sincere assertion. In particular, whether an agent counts as believing that p in a context depends on the space of alternative possibilities the agent is considering in that context. One and the (...) same doxastic state may amount to belief that p in one context but not another. The second part of the paper gives a formal treatment of doxastic states, according to which belief is context-sensitive along just these lines. The model is applied to characterize (but not to refute) skeptical arguments. (shrink)

Pascal Engel (2008) has insisted that a number of notable strategies for rejecting the knowledge norm of assertion are put forward on the basis of the wrong kinds of reasons. A central aim of this paper will be to establish the contrast point: I argue that one very familiar strategy for defending the knowledge norm of assertion—viz., that it is claimed to do better in various respects than its competitors (e.g. the justification and the truth norms)— relies on (...) a presupposition that is shown to be ultimately under motivated. That presupposition is the uniqueness thesis—that there is a unique epistemic rule for assertion, and that such a rule will govern assertions uniformly. In particular, the strategy I shall take here will be to challenge the sufficiency leg of the knowledge norm in a way that at the same time counts against Williamson’s (2000) own rationale for the uniqueness thesis. However, rather than to challenge the sufficiency leg of the knowledge norm via the familiar style of ‘expert opinion’ and, more generally, ‘second-hand knowledge’ cases (e.g. Lackey (2008)), a strategy that has recently been called into question by Benton (2014), I’ll instead advance a very different line of argument against the sufficiency thesis, one which turns on a phenomenon I call epistemic hypocrisy. (shrink)

Recent work has assumed that the normativity associated with assertion differs from the normativity of morality, practical rationality, etiquette, and legality. That is, whether an assertion “should” be made is not merely a function of these other familiar sorts of normativity and is especially connected to truth. Some researchers have challenged this assumption of distinctive normativity. In this paper I report two experiments that test the assumption. Participants read a brief story, judged whether an assertion should be (...) made, and rated several other qualities of the assertion, including its truth value, morality, rationality, etiquette, legality, and folly. Of these qualities, truth value most strongly predicted assertability. The findings support the assumption of distinctive normativity and provide further evidence that the norm of our social practice of assertion is factive. (shrink)

I report three experiments relevant to evaluating Krista Lawlor's theory of assurance, respond to her criticism of the knowledge account of assertion, and propose an alternative theory of assurance.

This paper focuses on Martin Montminy’s recent attempt to show that assertion and practical reasoning are necessarily governed by the same epistemic norm (“Why assertion and practical reasoning must be governed by the same epistemic norm”, Pacific Philosophical Quarterly [2013]). I show that the attempt fails. I finish by considering the upshot for the recent debate concerning the connection between the epistemic norms of assertion and practical reasoning.

If a speaker selflessly asserts that p, the speaker has good evidence that p is true, asserts that p on the basis of that evidence, but does not believe that p. Selfless assertions are widely thought to be acceptable, and therefore to pose a threat to the Knowledge Norm of Assertion. Advocates for the Knowledge Norm tend to respond to this threat by arguing that there are no such things as selfless assertions. They argue that those who appear to (...) be selfless asserters either: believe what they assert, perform a speech act other than assertion, or assert a proposition other than the one that they seem to. I argue that such counterarguments are unsuccessful. There really are selfless assertions. But I also argue that they are no threat to the Knowledge Norm. There is a good case to be made that knowledge does not require belief. And if it does not, then the fact that some selfless assertions are appropriate does not tell against the Knowledge Norm. Indeed, I argue that selfless asserters know the propositions that they assert to be true. (shrink)

I argue that rejection is a speech act that cannot be reduced to assertion. Adapting an argument by Huw Price, I conclude that rejection is best conceived of as the speech act that is used to register that some other speech act is (or would be) violating a rule of the conversation game. This can be naturally understood as registering *norm violations* where speech acts are characterised by their essential norms. However, I argue that rejection itself is not to (...) be characterised by a norm. Instead, registering violations is a necessary condition for understanding the normative framework in the first place. The core observation is that the concept of an 'illegal move' is intelligible, so a speech act can be (say) an assertion, despite violating the essential norm of asserting. Rejection has the function of pointing out that a move is illegal. But registering rule violations is a precondition of playing games with rules (it is part of the concept 'game'), not itself a rule in a game. A similar special role of rejection (that it is not explicable in the terms provided by a framework, but needed to conceptualise these terms) likely occurs in other frameworks as well, e.g. characterising speech acts by commitments or their effect on a common ground.

In this work, we consider the problem of the approximate hedging of a contingent claim in the minimum mean square deviation criterion. A theorem on martingaỉe representation in the case of discrete time and an application of obtained result for semi-continous market model are given.

Assertions are speech acts by means of which we express beliefs. As such they are at the heart of our linguistic and social practices. Recent research has focused extensively on the question whether the speech act of assertion is governed by norms, and if so, under what conditions it is acceptable to make an assertion. Standard theories propose, for instance, that one should only assert that p if one knows that p (the knowledge account), or that one should (...) only assert that p if p is true (the truth account). In a series of four experiments, this question is addressed empirically. Contrary to previous findings, knowledge turns out to be a poor predictor of assertability, and the norm of assertion is not factive either. The studies here presented provide empirical evidence in favour of the view that a speaker is warranted to assert that p only if her belief that p is justified. (shrink)

Evidence from life science, cognitive science, and philosophy supports the hypothesis that knowledge is a central norm of the human practice of assertion. However, to date, the experimental evidence supporting this hypothesis is limited to American anglophones. If the hypothesis is correct, then such findings will not be limited to one language or culture. Instead, we should find a strong connection between knowledge and assertability across human languages and cultures. To begin testing this prediction, we conducted three experiments on (...) Koreans in Korean. In each case, the findings replicated prior results observed in Americans and were corroborated by key findings from new replication studies on Americans using materials back-translated from Korean. These findings support the theory that there is a core, cross-culturally robust human practice of assertion and that, according to the rules of this practice, assertions should express knowledge.

According to Jonathan Kvanvig, the practice of taking back one’s assertion when finding out that one has been mistaken or gettiered fails to speak in favour of a knowledge norm of assertion. To support this claim, he introduces a distinction between taking back the content of the assertion, and taking back the speech act itself. This paper argues that Kvanvig’s distinction does not successfully face close speech-act-theoretic scrutiny. Furthermore, I offer an alternative diagnosis of the target cases (...) sourced in the normativity of action. (shrink)
