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)

Moorean constructions are famously odd: it is infelicitous to deny that you believe what you claim to be true. But what about claiming that p, only to immediately put into question your evidence in support of p? In this paper, we identify and analyse a class of quasi-Moorean constructions, which we label counterevidentials. Although odd, counterevidentials can be accommodated as felicitous attempts to mitigate one’s claim right after making it. We explore how counterevidentials differ from lexicalised mitigation operators, parentheticals, and (...) anaphoric mitigation devices, and consider some cognate non-assertoric constructions. We conclude by exploring the implications of our analysis for theorising about linguistic responsibility, assertion, and lying. (shrink)

This paper offers a systematic classification and characterization of speech acts and their norms. Recently, the normative approach has been applied to various speech acts, most notably to constatives. I start by showing how the work on the norms of assertion has influenced various approaches to the norms of other speech acts. I focus on the fact that various norms of assertion have different extensions, i.e., they denote different clusters of illocutions as belonging to an assertion. I argue that this (...) has consequences for theorising about norms of other speech acts and generates certain arbitrary divisions. In the central part, I analyse two groups of speech acts. Firstly, ordinary speech acts, like predictions or retractions. Secondly, I indicate how the normative view can be extended to so-called ancillary speech acts, like presuppositions or implicatures. I end with a discussion of possible extensions of the normative approach, focusing on the debate on lying. (shrink)

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

Generalisation, universal knowledge claims, and recommendations within disaster studies are problematic because they lead to miscommunication and the misapplication of actionable knowledge. The consequences and impacts thereof are not often considered by experts; forgone as irrelevant to the academic division of labour. There is a disconnect between expert assertions for disaster risk reduction (DRR) and their practical suitability for laypersons. Experts currently assert independently of the context within which protective action measures (PAMs) are to be used, measures unconnected to the (...) people for whom they are developed. This has knock-on effects for DRR: much expert-generated science and policy remains unused, unimplemented, and sometimes misapplied. I use philosophical accounts of assertion and epistemic blame to highlight the epistemic relationship between experts and laypersons. This relationship includes responsibilities and agreements between epistemic agents. Since multilevel DRR knowledge still transfers top-down from experts to laypersons, if experts impair the epistemic relationship, they can be held epistemically blameworthy. To address the pervasiveness of top-down systems, I analyse the epistemic framings and narratives currently shaping DRR, and more specifically PAMs and campaigns. I deconstruct universal perspectives that dominate the epistemic processes of generating, disseminating, and implementing DRR knowledge and specifically for co-seismic landslide PAMs for Nepal. I argue for more inclusive, contextual, and epistemically responsible DRR. Co-production of knowledge should begin from the standpoints of marginalised persons who may have an epistemic advantage due to their socio-politically marginalised positions. Often these epistemic contributions are left out of DRR efforts because marginalised persons are rarely afforded equal, if any, epistemic agency, which results in epistemic gaps and a large pool of relevant knowledge remaining unincorporated and unused in DRR research and policy.

Speech acts are governed by a variety of illocutionary norms. Building on Sbisà’s (2019) work, this chapter attempts to develop a common framework to study them. Four families of illocutionary rules are identified: (i) Validity rules set conditions for (actual) performance; (ii) Cooperative rules set conditions for cooperative performance; (iii) Illocutionary goals set conditions for successful performance; (iv) Illocutionary obligations set conditions for compliance. Illocutionary rules are often taken to play a constitutive role: speech acts are said to be constituted (...) by the unique set of rules that regulates them. Against this view, it is argued that many illocutionary rules are instead best construed as rationally derivable expectations of cooperation. This alternative paradigm provides fertile ground to reconcile scholarly disagreement between speech act theorists, and yields a promising explanation of how illocutionary norms are learned and evolve through time.

Asserting is the act of claiming that something is the case—for instance, that oranges are citruses, or that there is a traffic congestion on Brooklyn Bridge (at some time). We make assertions to share information, coordinate our actions, defend arguments, and communicate our beliefs and desires. Because of its central role in communication, assertion has been investigated in several disciplines. Linguists, philosophers of language, and logicians rely heavily on the notion of assertion in theorizing about meaning, truth and inference. -/- (...) The nature of assertion and its relation to other speech acts and linguistic phenomena (implicatures, presuppositions, etc.) have been subject to much controversy. This entry will situate assertion within speech act theory and pragmatics more generally, and then go on to present the current main accounts of assertion. (shrink)

How should we account for the contextual variability of knowledge claims? Many philosophers favour an invariantist account on which such contextual variability is due entirely to pragmatic factors, leaving no interesting context-sensitivity in the semantic meaning of ‘know that.’ I reject this invariantist division of labor by arguing that pragmatic invariantists have no principled account of embedded occurrences of ‘S knows/doesn’t know that p’: Occurrences embedded within larger linguistic constructions such as conditional sentences, attitude verbs, expressions of probability, comparatives, and (...) many others, I argue, give rise to a threefold problem of embedded implicatures.

We review the "Entitlement" projects of Tyler Burge and Crispin Wright in light of recent work from and surrounding both philosophers. Our review dispels three misunderstandings. First, Burge and Wright are not involved in a common “entitlement” project. Second, though for both Wright and Burge entitlement is the new notion, “entitlement” is not some altogether third topic not clearly connected to the nature of knowledge or the encounter with skepticism. Third, entitlement vs. justification does not align with the externalism vs. (...) internalism distinction. (shrink)

Fogelin’s neo-Pyrrhonism is skepticism about epistemology and philosophy more generally. Philosophical reflection on ordinary epistemic practices leads us to deny the possibility of knowledge and justified belief. However, instead of accepting the dogma that knowledge and justified beliefs are impossible, a neo-Pyrrhonist rejects the philosophical premises that lead to this conclusion. Fogelin argues in particular that contemporary theories of justification cannot avoid dogmatic skepticism, because they are committed to the premises of the skeptical argument deriving from the modes of Agrippa. (...) It is argued against Fogelin that those theories can and typically do deny one or another of the premises and thus can avoid the skeptical conclusion. Neo-Pyrrhonism should rather be defended by arguing that the premises of the Agrippan argument are intuitively plausible and that neo-Pyrrhonism provides the best resolution of the resulting paradox. Only neo-Pyrrhonism both explains the intuitive plausibility of the premises and avoids dogmatic skepticism. (shrink)

In recent years, much attention has been given to the epistemic credentials of belief based on moral testimony. Some people think pure moral deference is wrong, others disagree. It comes as a surprise, however, that while the epistemic responsibilities of the receiver of moral testimony have been closely scrutinized, little to no discussion has focused on the epistemic duties of the speaker. This paper aims to supply this lack: it defends a function-first account of the normativity of moral assertion. According (...) to this view, in virtue of its function of reliably generating understanding in the audience, a moral assertion that p needs be knowledgeable and accompanied by a contextually appropriate explanation why p.

Everyone agrees that not all norms that govern belief and assertion are epistemic. But not enough attention has been paid to distinguishing epistemic norms from others. Norms in general differ from merely evaluative standards in virtue of the fact that it is fitting to hold subjects accountable for violating them, provided they lack an excuse. Different kinds of norm are most readily distinguished by their distinctive mode of accountability. My thesis is roughly that a norm is epistemic if and only (...) if its violation makes it fitting to reduce epistemic trust in the subject, even if there is no doubt about their sincerity, honesty, or other moral virtues. That is, violations of epistemic norms don’t merit resentment or other forms of blame, but rather deduction of credibility points in internal scorekeeping and related attitudinal and behavioral changes. As Fricker’s work on epistemic injustice shows, such distrust is undesirable from the point of view of an epistemic agent. Consequently, when one manifests epistemic distrust towards a subject in suitable circumstances, it amounts a way of holding her accountable. Since this form of accountability involves no opprobrium, there is good reason to think it is not linked to voluntary control in the same way as moral accountability. Finally, I make use of this account of what makes epistemic norms distinctive to point out some faulty diagnostics in debates about norms of assertion. My aim is not to defend any substantive view, however, but only to offer tools for identifying the right kind of evidence for epistemic norms. (shrink)

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)

The paper critically examines recent work on justifications and excuses in epistemology. I start with a discussion of Gerken’s claim that the “excuse maneuver” is ad hoc. Recent work from Timothy Williamson and Clayton Littlejohn provides resources to advance the debate. Focusing in particular on a key insight in Williamson’s view, I then consider an additional worry for the so-called excuse maneuver. I call it the “excuses are not enough” objection. Dealing with this objection generates pressure in two directions: one (...) is to show that excuses are a positive enough normative standing to help certain externalists with important cases; the other is to do so in a way that does not lead back to Gerken’s objection. I show how a Williamson-inspired framework is flexible enough to deal with both sources of pressure. Perhaps surprisingly, I draw on recent virtue epistemology. (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)

In this paper, I argue against recent versions of justification norms of action and practical deliberation . I demonstrate that these norms yield unacceptable results in deception cases. However, a further modification of justification norms in the light of these results appears to be ad hoc. Hence, I claim, we should reject justification norms of action and practical deliberation.

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

I discuss three understandings of the idea of “Knowledge First Epistemology”, i.e. Timothy Williamson’s suggestion that we should take knowledge as a starting point, rather than trying to analyze it. Some have taken this to be a suggestion about the role of the concept of knowledge, but Williamson also seems to be concerned with intuition-based metaphysics. As an alternative, I develop the idea that knowledge may be a social kind that can be understood through a functional analysis in the tradition (...) of Edward Craig. (shrink)

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

The five modes are a list of tools used by ancient sceptics to guide dogmatic people towards suspending their judgement. Attributed to Agrippa and used extensively by Sextus Empiricus, these modes are still widely discussed today by epistemologists and specialists in ancient philosophy. Scholars disagree, however, on how to understand the way the five modes are used together and what the logical form of the sceptical strategy behind their deployment is. This paper offers a reconstruction of the system of the (...) five modes that avoids these problems. In specific, unlike previous reconstructions, it includes a non-trivial version of the mode of relativity, avoids committing the sceptic to a normative principle and follows the textual evidence more closely. Moreover, I argue that the system can be better understood as a list of steps in a process, whose underlying logic can be expressed by a single algorithm. (shrink)

This thesis addresses philosophical problems concerning improper assertions. The first part considers the issue of defining lying: here, against a standard view, I argue that a lie need not intend to deceive the hearer. I define lying as an insincere assertion, and then resort to speech act theory to develop a detailed account of what an assertion is, and what can make it insincere. Even a sincere assertion, however, can be improper (e.g., it can be false, or unwarranted): in the (...) second part of the thesis, I consider these kinds of impropriety. An influential hypothesis maintains that proper assertions must meet a precise epistemic standard, and several philosophers have tried to identify this standard. After reviewing some difficulties for this approach, I provide an innovative solution to some known puzzles concerning the permissibility of false assertions. In my view, assertions purport to aim at truth, but they are not subject to a norm that requires speakers to assert a proposition only if it is true. (shrink)

This paper has two central aims. First, we motivate a puzzle. The puzzle features four independently plausible but jointly inconsistent claims. One of the four claims is the sufficiency leg of the knowledge norm of assertion (KNA-S), according to which one is properly epistemically positioned to assert that p if one knows that p. Second, we propose that rejecting (KNA-S) is the best way out of the puzzle. Our argument to this end appeals to the epistemic value of intellectual humility (...) in social-epistemic practice.

The term ‘epistemic trespassing’ has recently been coined to denote a person’s judgments regarding a domain where they are not epistemic experts. In this paper, I focus on expert trespassing testimony – that is, testimony by an expert in a domain of expertise other than his own. More specifically, I focus on intra-scientific trespassing testimony between scientific collaborators. By developing a number of distinctions, I argue that while intra-scientific trespassing testimony may seriously hamper scientific collaboration, it does not invariably do (...) so and may even be beneficial to it. (shrink)

What is the epistemic position that a scientist must be in vis-à-vis a proposition, p, to be in a good enough epistemic position to assert that p to a fellow scientist within the scientific process? My aim is to provide an answer to this question and, more generally, to connect the epistemological debates about the epistemic norms of assertion to the debates about the nature of the scientific process. The question is important because science is a collaborative enterprise based on (...) a division of labor. It has even been suggested that such collaboration is a part of the scientific method. However, scientific collaboration depends upon communication between scientists—that is, intra-scientific testimony. After distinguishing some different kinds of intra-scientific testimony, I provide a specific proposal for an epistemic norm of assertion that generally governs such testimony. I argue that the proposal aligns with the requirements of three scientific virtues—replicability, revisability, and accountability. The discussion of replicability considers a prominent debate in the social and cognitive sciences. In conclusion, I consider some of the wider questions raised by characterizing scientific collaboration, division of labor, and more generally, scientific method via intra-scientific testimony.

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

In this response to Michael Blome-Tillmann's comments on On Folk Epistemology, I defend the book's epistemic focal bias account of the salient alternatives effect that Blome-Tillmann takes to motivate epistemic contextualism. First, I defend the epistemic focal bias account against Blome-Tillmann's criticism that it is insufficiently general insofar as it fails to account for a range of cases. Second, I defend the epistemic focal bias account from Blome-Tillmann's charge that it overgeneralizes insofar as it can ‘explain away the context-sensitivity of (...) gradable adjectives.’ Along the way, I discuss the metaphilosophical principles that guide the epistemic focal bias account.

Outcome bias and hindsight bias are important in philosophical debates and have wide-ranging implications outside of philosophy. Recently, Hedden has articulated a novel line of argumnt that the empirical evidence for what he labels hindsight bias is largely misguided and that empirical researchers who postulate such a bias are engaged in a fallacy fallacy. In this paper, I articulate Hedden’s core insights in terms of two principles and argue that in the relevant empirical research, these principles are often (i) recognized, (...) (ii) invoked in theoretical explanation, and (iii) guiding study designs and interpretation of data. On this basis, I argue that there is ample empirical evidence for outcome and hindsight bias and that cognitive psychologists do not generally exhibit a fallacy fallacy of postulating such biases in cases where there are none. More constructively, the present paper articulates some general principles that help us to better understand when an empirical study provides evidence of these types of bias. Thus, the debate casts light on both the specific evidence for outcome and hindsight bias but also on the general division of labor between philosophy and psychology. (shrink)

This paper introduces and defends the paradigm response to external world skepticism. To understand it, consider an analogy. One of the hallmarks of being a bird is an ability to fly. A penguin lacks this hallmark and thus fails to be a paradigm bird. Likewise, there are various hallmarks of knowledge. Some of your external world beliefs lack some of these hallmarks, and thus fail to be paradigm cases of knowledge. Just as the inability of penguins to fly doesn’t prevent (...) them from being birds, likewise the lack of these hallmarks doesn’t prevent your beliefs from being knowledge. It just prevents them from being paradigm cases thereof. (shrink)

The paper draws on philosophy of science to help resolve a tension between two central journalistic ideals: That of resenting diverse viewpoints (Balanced Reporting) and that of presenting the most reliable testimony (Reliable Reporting). While both of these ideals are valuable, they may be in tension. This is particularly so when it comes to scientific testimony and science reporting. Thus, we face a hard question: How should and be balanced in science reporting? The present paper contributes substantive proposals in a (...) manner that integrates philosophy of science with the recent empirical literature on science communication. Specifically, I articulate and evaluate strategies for balancing Balanced Reporting and Reliable Reporting. First, I provide a diagnosis of the conflict between them that is informed by philosophy of science. On this basis, I provide restrictions of both Balanced Reporting and Reliable Reporting. The restrictions are unified because they are inspired by similar reflections about the epistemic basis of science reporting—namely scientific justification. Moreover, I note some empirical work that supports the restrictions as well as some empirical work that indicates some limitations of them. Thus, the paper exemplifies how an empirically informed philosophy of science may bear on a question of societal concern. (shrink)

Scientific expert testimony is crucial to public deliberation, but it is associated with many pitfalls. This article identifies one—namely, expert trespassing testimony—which may be characterized, crudely, as the phenomenon of experts testifying outside their domain of expertise. My agenda is to provide a more precise characterization of this phenomenon and consider its ramifications for the role of science in society. I argue that expert trespassing testimony is both epistemically problematic and morally problematic. Specifically, I will argue that scientific experts are (...) subject to a particular obligation. Roughly, this is the obligation to qualify their assertions when speaking outside their domain of scientific expertise in certain contexts. Thus, I argue that scientists who possess expert knowledge are confronted with hard questions about when and how to testify and, therefore, that being a scientific expert comes with great responsibility. Consequently, I provide a concrete “expert guideline” according to which scientific experts, in certain contexts, face an obligation to qualify their assertions when speaking outside their domain of expertise. Furthermore, I consider a number of the conditions in which the guideline is waived or overridden. On this basis, I consider the broader aspects of the roles of scientific experts in a society with a high division of cognitive labor that calls for trust in scientific expert testimony. (shrink)

Several studies have found a robust effect of truth on epistemic evaluation of belief, decision, action and assertion. Thus, truth has a significant effect on normative participant evaluations. Some theorists take this truth effect to motivate factive epistemic norms of belief, action, assertion etc. In contrast, I argue that the truth effect is best understood as an epistemic instance of the familiar and ubiquitous phenomenon of outcome bias. I support this diagnosis from three interrelating perspectives: (1) by epistemological theorizing, (2) (...) by considerations from cognitive psychology and (3) by methodological reflections on the relationship between folk epistemology and epistemological theorizing.

This paper aims to develop a novel account of the normativity of assertion. Its core thesis is that assertion has an etiological epistemic function, viz. to generate knowledge in hearers. In conjunction with a general account of etiological functions and their normative import, it is argued that an assertion is epistemically good if and only if it has the disposition to generate knowledge in hearers. In addition, reason is provided to believe that it makes sense to regulate the practice of (...) assertion by a speaker rule—and, more specifically, by a knowledge rule—as so regulating assertion contributes to ensuring that assertion fulfils its etiological function reliably.

This paper offers an analysis of the structure of epistemic vice-charging, the critical practice of charging other persons with epistemic vice. Several desiderata for a robust vice-charge are offered and two deep obstacles to the practice of epistemic vice-charging are then identified and discussed. The problem of responsibility is that few of us enjoy conditions that are required for effective socialisation as responsible epistemic agents. The problem of consensus is that the efficacy of a vice-charge is contingent upon a degree (...) of consensus between critic and target that is unlikely or impossible where vice-charging is most likely to be provoked. It emerges that a robust critical practice of vice-charging is possible in principle, but very difficult in practice. (shrink)

I discuss Lawlor’s Austinian account of knowledge ascriptions and argue that it is a brand of pragmatic encroachment. I then criticize the motivation for pragmatic encroachment theories that derives from assumptions about the functional role of knowledge ascriptions. I argue that this criticism also apply to contextualist followers of Craig. Finally, I suggest that the central lesson from reflection on the communicative functions of knowledge ascriptions is that they, upon reflection, motivate traditional invariantism.

In this paper, I challenge a widely presupposed principle in the epistemology of inference. The principle, (Validity Requirement), is this: S’s (purportedly deductive) reasoning, R, from warranted premise-beliefs provides (conditional) warrant for S’s belief in its conclusion only if R is valid. I argue against (Validity Requirement) from two prominent assumptions in the philosophy of mind: that the cognitive competencies that constitute reasoning are fallible, and that the attitudes operative in reasoning are anti-individualistically individuated. Indeed, my discussion will amount to (...) a defence of anti-individualism against a novel ‘slow-switch’ argument against it. This argument contra anti-individualism has it that given anti-individualism and certain auxiliary assumptions, A, a switched reasoner may, in certain slow-switch circumstances, C, reason invalidly by equivocating concepts. More specifically: -/- (Valid 0): Peter is in circumstances C, and auxiliary assumptions, A, hold.(Valid 1): If Peter is in circumstances C, and auxiliary assumptions A hold, then (if the attitudes operative in Peter’s reasoning R are anti-individualistically individuated, then R is not valid). (Valid 2): Peter’s reasoning, R, generates warrant for the conclusion-belief. (Valid 3): Peter’s reasoning, R, generates warrant for the conclusion-belief only if the reasoning, R, is valid. (Valid 4): So, the attitudes operative in Peter’s reasoning R are not anti-individualistically individuated. -/- The argument involves weaker premises than those of familiar slow-switch arguments against anti-individualism. In particular, it requires only that the reasoning be de facto valid. This assumption is much weaker than the requirement that the validity of the reasoning be ‘transparent’ to the reasoner. Indeed, (Valid 3) is simply an instance of (Validity Requirement). However, I argue that anti-individualism and (Valid 0)–(Valid 2) should be upheld at the expense of (Valid 3). In consequence, (Validity Requirement) stands in need of restriction. Thus, I argue for a surprising result in the epistemology of inference from widely accepted assumptions in the philosophy of mind. (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.

Recent developments in technologically enabled social cognition call for a rethinking of many aspects of human cognition. According to the hypothesis of extended cognition, we must revise our psychological categories by eliminating allegedly superficial distinctions between internal cognition and external processes. As an alternative to this proposal, I outline a hypothesis of outsourced cognition which seeks to respect distinctions that are operative in both folk psychology and the social and cognitive sciences. According to this hypothesis, the cognitive states and processes (...) of the individual are substantially and explanatorily distinct from the relevant external states and processes. In consequence, the individual remains a cognitive unit that is both central and indispensable in the explanations of cognitive science. As a case study, I consider the epistemology of testimony. I will argue that important epistemological categories may be preserved by adopting the hypothesis of outsourced cognition over the hypothesis of extended cognition. Moreover, I will argue that the outsourced cognition hypothesis deepens the problems that beset an extended epistemology of testimony. (shrink)

What is the relationship between the epistemic norms of assertion and the epistemic norms of action/practical reasoning? Brown argues that the standards for practical reasoning and assertion are distinct (Brown 2012). In contrast, Montminy argues that practical reasoning and assertion must be governed by the same norm (Montminy 2012). Likewise, McKinnon has articulated an argument for a unified account from cases of isolated second-hand knowledge (McKinnon 2012). To clarify the issue, I articulate a distinction between Equivalence Commonality and Structural Commonality. (...) I then argue against the former by counterexamples that doubly dissociate the standards for assertion and action. Furthermore, I argue that such a double dissociation compromises knowledge accounts of both assertion and action/practical reasoning. To provide a more accurate diagnosis, I consider speech act theory and argue that principled differences between the norms of action and assertion compromise Equivalence Commonality. In contrast, a qualified version of Structural Commonality may be preserved. (shrink)

In recent literature, a very popular position about the normativity of assertion claims that standards for epistemically proper assertion vary with practical context, while standards for knowledge do not. This paper shows this claim is strongly incompatible with the received value-theoretic view regarding the relationship between the axiological and the deontic: one of the two has to go.

ABSTRACT Many epistemologists explain the empirically attested contextual variation in knowledge ascriptions by appeal to a kind of warranted assertability maneuver that finds the locus of variability in epistemic norms of assertion. I show that this way to WAM fails. It cannot explain the variability of embedded uses of knowledge sentences in assertoric speech acts in which the knowledge sentences are not themselves asserted.

DeRose famously argued that, given that assertability varies with practical context, we cannot combine a biconditional knowledge norm of assertion with classical invariantism. The first aim of this paper is to show that De Rose's argument is ultimately unsuccessful. Second, I develop a view, entitled Assertion Functionalism, which combines the knowledge norm with classical invariantism and at the same time offers an appealing account of the intuitive variability of proper assertion.

While much interdisciplinarity brings together proximate fields, broad interdisciplinarity sees integration between disciplines that are perceived to be non-neighboring. This paper argues that the heterogeneity among disciplines in broad interdisciplinarity calls for stricter epistemic norms of testimony for experts that act as translators between the disciplines than those suggested for intra-scientific testimony. The paper is structured around two case studies: the affective turn in social theorizing and the use of quantum mechanics in critical theory as exemplified by Vicky Kirby’s use (...) of work by Karen Barad. These are argued to be instances of broad interdisciplinary borrowing where few translators have joint expertise in both disciplines. For most, therefore, the engagement with for instance the integration between quantum mechanics and critical theory is possible only by the aid of translators. For those without sufficient interactional expertise, however, the epistemic credentials of the translations they inevitably rely upon are inscrutable. Furthermore, any comparison between translations is challenged since translations are argued to be few due to the cognitive divergence between disciplines in broad interdisciplinarity. Consequently, the epistemic integrity of broad interdisciplinarity can only be secured through additional norms of testimony for translators. The paper proposes that (a) all translator’s testimony in broad interdisciplinarity must aim to be neutral with respect to disputed issues within the relevant disciplines and (b) any deviation from (a) must be clearly highlighted.

We report and discuss the results of a series of experiments that address a contrast effect exhibited by folk judgments about knowledge ascriptions. The contrast effect, which was first reported by Schaffer and Knobe, is an important aspect of our folk epistemology. However, there are competing theoretical accounts of it. We shed light on the various accounts by providing novel empirical data and theoretical considerations. Our key findings are, firstly, that belief ascriptions exhibit a similar contrast effect and, secondly, that (...) the contrast effect is systematically sensitive to the content of what is in contrast. We argue that these data pose significant challenges to contrastivist accounts of the contrast effect. Furthermore, some of the data set provides, in conjunction with some non-empirical epistemological arguments, some limited evidence for what we call a focal bias account of the data. According to the focal bias account, the contrast effects arise at least in part because epistemically relevant facts are not always adequately processed when they are presented in certain ways.
