Moore’s paradox, the infamous felt bizarreness of sincerely uttering something of the form “I believe grass is green, but it ain’t”—has attracted a lot of attention since its original discovery (Moore 1942). It is often taken to be a paradox of belief—in the sense that the locus of the inconsistency is the beliefs of someone who so sincerely utters. This claim has been labeled as the priority thesis: If you have an explanation of why a putative content could not be (...) coherently believed, you thereby have an explanation of why it cannot be coherently asserted. (Shoemaker 1995). The priority thesis, however, is insufficient to give a general explanation of Moore-paradoxical phenomena and, moreover, it’s false. I demonstrate this, then show how to give a commitment-theoretic account of Moore Paradoxicality, drawing on work by Bach and Harnish. The resulting account has the virtue of explaining not only cases of pragmatic incoherence involving assertions, but also cases of cognate incoherence arising for other speech acts, such as promising, guaranteeing, ordering, and the like.

In a recent paper, Philip Kremer proposes a formal and theory-relative desideratum for theories of truth that is spelled out in terms of the notion of ‘no vicious reference’. Kremer’s Modified Gupta-Belnap Desideratum (MGBD) reads as follows: if theory of truth T dictates that there is no vicious reference in ground model M, then T should dictate that truth behaves like a classical concept in M. In this paper, we suggest an alternative desideratum (AD): if theory of truth T dictates (...) that there is no vicious reference in ground model M, then T should dictate that all T-biconditionals are (strongly) assertible in M. We illustrate that MGBD and AD are not equivalent by means of a Generalized Strong Kleene theory of truth and we argue that AD is preferable over MGBD as a desideratum for theories of truth.

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)

Rae Langton and Jennifer Hornsby provide accounts of how pornography silences women by appealing to J.L. Austin's account of speech-acts. Since their accounts focus only on instances of silencing where the hearer does not grasp the type of speech-act the speaker intends to perform, their accounts of silencing do not generalize to explain silencing that arises from what Miranda Fricker calls “testimonial injustice.” I argue that silencing arising from testimonial injustice can only be explained by what we shall call the (...) dialectical account of assertion, according to which assertion is the undertaking of a commitment in reasoned discourse. In doing so, I show that accounts of assertion based on speakers' intentions, proposals to common ground, and constitutive norms do not provide the necessary framework to explain silencing within the context of testimonial injustice. Having shown the strength of the dialectical account in explaining silencing, I conclude that the dialectical account also provides a way to remedy some instances of silencing arising from testimonial injustice providing further evidence that the dialectical account is the correct account of assertion.

This paper is about how moral disagreement matters for metaethics. It has four parts. In the first part I argue that moral facts are subject to a certain epistemic accessibility requirement. Namely, moral facts must be accessible to some possible agent. In the second part I show that because this accessibility requirement on moral facts holds, there is a route from facts about the moral disagreements of agents in idealized conditions to conclusions about what moral facts there are. In the (...) third part I build on this route to show that (*) if there is significant moral disagreement in idealized conditions, then our understanding of morality is fatally flawed and we should accept relativism over non-naturalism and quasi-realism. So, if, like many, you think that there would be significant moral disagreement in idealized conditions, you should hold that our understanding of morality is fatally flawed and reject non-naturalism and quasi-realism. In the fourth part of this paper I show that (*) undermines the plausibility of non-naturalism, quasi-realism, and the view that our understanding of morality is not fatally flawed even if we do not have sufficient reason to believe that there would be significant moral disagreement in idealized conditions.

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)

Groups, like individuals, can communicate. They can issue statements, make promises, give advice. Sometimes, in doing so, they lie and deceive. The goal of this paper is to offer a precise characterisation of what it means for a group to make an assertion and to lie. I begin by showing that Lackey’s influential account of group assertion is unable to distinguish assertions from other speech acts, explicit statements from implicatures, and lying from misleading. I propose an alternative view, according to (...) which a group asserts a proposition only if it explicitly presents that proposition as true, thereby committing to its truth. This proposal is then put to work to define group lying. While scholars typically assume that group lying requires (i) a deceptive intent and (ii) a belief in the falsity of the asserted proposition, I offer a definition that drops condition (i) and significantly broadens condition (ii).

Sentences with slifting parentheticals The formal analysis of natural language, Mouton, The Hague, 1973) grammaticalize an intriguing interaction between truth-conditional meaning and speech act function. In such sentences, the assertion strength of the slifted clause is modulated by the parenthetical, which provides evidential support :480–496, 1952; Asher in J Semant 17:31–50, 2000; Rooryck in Glot Int 5:125–133, 2001; Jayez and Rossari in: Corblin, de Swart Handbook of French semantics, CSLI, Stanford, 2004; Davis et al. in Proc Semant Linguist Theory 17:71–88, (...) 2007; Simons in Lingua 117:1034–1056, 2007; Murray in Semant Pragmat 7:1–53, 2014; Maier and Bary in: Brochhagen et al. Proceedings of the 20th Amsterdam colloquium, 2015; AnderBois in Semant Pragmat 9:1–55, 2016; Hunter in Dialogue Discourse 7:1–35, 2016). Starting with the idea that assertability comes in degrees, this paper develops a probabilistic updatemodel that captures the role of parentheticality as a language tool for qualifying commitments. A crucial role here is played by the rule of Jeffrey conditionalization, which factors in the uncertainty of the parenthetical information itself. The model also derives certain effects of parenthetical modification not found in regular embedding constructions, including the fact that slifting parentheticals are limited to creating upward-entailing environments.

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)

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

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

I outline a number of parallels between trust and distrust, emphasising the significance of situations in which both trust and distrust would be an imposition upon the (dis)trustee. I develop an account of both trust and distrust in terms of commitment, and argue that this enables us to understand the nature of trustworthiness. Note that this article is available open access on the journal website.

Knowledge ascriptions of the form ‘S knows that p’ are a central area of research in philosophy. But why do humans think and talk about knowledge? What are knowledge ascriptions for? This article surveys a variety of proposals about the role of knowledge ascriptions and attempts to provide a unified account of these seemingly distinct views.

Who should be the author(s) of an academic paper? This question is becoming increasingly pressing, due to the increasing prevalence and scale of scientific collaboration, and the corresponding diversity of authorship practices in different disciplines and subdisciplines. This paper addresses the conceptual issues underlying authorship, with an eye to ameliorating authorship practices. The first part of the paper distinguishes five roles played by authorship attributions: allocating credit, constructing a speaker, enabling credibility judgements, supporting accountability, and creating an intellectual marketplace. The (...) second part of the paper argues that distinguishing these functions helps us see that at least some of the confusions around authorship are due to tensions between these functions. The final part of the paper suggests a way to resolve these conceptual confusions, which we will call the CSWG proposal. This proposal suggests replacing authorship with a bundle of roles tailored to the functions of authorship—contributor, spokesperson, writer, and guarantor—which can be distributed in a number of different ways.

In this paper we apply social epistemology to mathematical proofs and their role in mathematical knowledge. The most famous modern collaborative mathematical proof effort is the Classification of Finite Simple Groups. The history and sociology of this proof have been well-documented by Alma Steingart (2012), who highlights a number of surprising and unusual features of this collaborative endeavour that set it apart from smaller-scale pieces of mathematics. These features raise a number of interesting philosophical issues, but have received very little (...) attention. In this paper, we will consider the philosophical tensions that Steingart uncovers, and use them to argue that the best account of the epistemic status of the Classification Theorem will be essentially and ineliminably social. This forms part of the broader argument that in order to understand mathematical proofs, we must appreciate their social aspects. (shrink)

Descriptive semantic theories purport to characterize the meanings of the expressions of languages in whatever complexity they might have. Foundational semantics purports to identify the kind of considerations relevant to establish that a given descriptive semantics accurately characterizes the language used by a given individual or community. Foundational Semantics I presents three contrasting approaches to the foundational matters, and the main considerations relevant to appraise their merits. These approaches contend that we should look at the contents of speakers’ intuitions; at (...) the deep psychology of users and its evolutionary history, as revealed by our best empirical theories; or at the personal‐level rational psychology of those subjects. Foundational Semantics II examines a fourth view, according to which we should look instead at norms enforced among speakers. The two papers aim to determine in addition the extent to which the approaches are really rival, or rather complementary. (shrink)

It is valuable for inquiry to have researchers who are committed advocates of their own theories. However, in light of pervasive disagreement, such a commitment is not well explained by the idea that researchers believe their theories. Instead, this commitment, the rational attitude to take toward one’s favored theory during the course of inquiry, is what I call endorsement. Endorsement is a doxastic attitude, but one which is governed by a different type of epistemic rationality. This inclusive epistemic rationality is (...) sensitive to reasons beyond those to think the particular proposition in question is true. Instead, it includes extrinsic epistemic reasons, which concern the health of inquiry more generally. Such extrinsic reasons include the distribution of cognitive labor that a researcher will contribute to by endorsing a particular theory. Recognizing endorsement and inclusive epistemic rationality thus allows us to smooth a tension between individual rationality and collective rationality. It does so by showing how it can be epistemically rational to endorse a theory on the basis of the way this endorsement will benefit collective inquiry. I provide a decision theoretic treatment for inclusive epistemic rationality and endorsement which illustrates how this can be accomplished. (shrink)

Epistemic injustice is a kind of injustice that arises when one’s capacity as an epistemic subject is wrongfully denied. In recent years it has been argued that psychiatric patients are often harmed in their capacity as knowers and suffer from various forms of epistemic injustice that they encounter in psychiatric services. Acknowledging that epistemic injustice is a multifaceted problem in psychiatry calls for an adequate response. In this paper I argue that, given that psychiatric patients deserve epistemic respect and have (...) a certain epistemic privilege, healthcare professionals have a pro tanto epistemic duty to attend to and/or solicit reports of patients’ first-person experiences in order to prevent epistemic losses. I discuss the nature and scope of this epistemic duty and point to one interesting consequence. In order to prevent epistemic losses, healthcare professionals may need to provide some patients with resources and tools for expressing their experiences and first-person knowledge, such as those that have been developed within the phenomenological approach. I discuss the risk of secondary testimonial and hermeneutical injustice that the practice of relying on such external tools might pose and survey some ways to mitigate it. (shrink)

As a general rule, whenever a hearer is justified in forming the belief that p on the basis of a speaker’s testimony, she will also be justified in assuming that the speaker has formed her belief appropriately in light of a relevantly large and representative sample of the evidence that bears on p. In simpler terms, a justification for taking someone’s testimony entails a justification for trusting her assessment of the evidence. This introduces the possibility of what I will call (...) “evidential preemption.” Evidential preemption occurs when a speaker, in addition to offering testimony that p, also warns the hearer of the likelihood that she will subsequently be confronted with apparently contrary evidence: this is done, however, not so as to encourage the hearer to temper her confidence in p in anticipation of that evidence, but rather to suggest that the (apparently) contrary evidence is in fact misleading evidence or evidence that has already been taken into account. Either way, the speaker is signalling to the hearer that the subsequent disclosure of this evidence will not require her to significantly revise her belief that p. Such preemption can effectively inoculate an audience against future contrary evidence, and thereby creates an opening for a form of exploitative manipulation that I will call “epistemic grooming.” Nonetheless, I argue, not all uses of evidential preemption are nefarious; it can also serve as an important tool for guiding epistemically limited agents though complex evidential scenarios.

A critique of conversational epistemic contextualism focusing initially on why pragmatic encroachment for knowledge is to be avoided. The data for pragmatic encroachment by way of greater costs of error and the complementary means to raise standards of introducing counter-possibilities are argued to be accountable for by prudence, fallibility and pragmatics. This theme is sharpened by a contrast in recommendations: holding a number of factors constant, when allegedly higher standards for knowing hold, invariantists still recommend assertion (action), while contextualists do (...) not. Given the knowledge norm of assertion, if one recommendation is preferable to the other, the result favors the preferred recommendation's account of knowledge. In the final section, I offer a unification of these criticisms centering on the contextualist use of 'epistemic position'. Their use imposes on threshold notions of justification, warrant, or knowledge tests that are suitable only to unlimited comparative or scalar notions like confidence or certainty and places them at one with an important strand of sceptical reasoning.

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.
