This paper aims to clear up the epistemology of learning morality from Artificial Moral Advisors (AMAs). We start with a brief consideration of what counts as moral enhancement and consider the risk of deskilling raised by machines that offer moral advice. We then shift focus to the epistemology of moral advice and show when and under what conditions moral advice can lead to enhancement. We argue that people’s motivational dispositions are enhanced by inspiring people to act morally, instead of merely (...) telling them how to act. Drawing upon these insights, we claim that if AMAs are to genuinely enhance people morally, they should be designed as inspiration and not authority machines. In the final section, we evaluate existing AMA models to shed light on which holds the most promise for helping to make users better moral agents. (shrink)

This handbook article gives a critical overview of recent discussions of epistemic authority. It favors an account that brings into balance the dictates of rational deference with the ideals of intellectual self-governance. A plausible starting point is the conjecture that neither should rational deference to authorities collapse into total epistemic submission, nor the ideal of mature intellectual self-governance be conflated with (illusions of) epistemic autarky.

A key debate in the epistemology of testimony concerns when it is reasonable to acquire belief through accepting what a speaker says. This debate has been largely understood as the debate over how much, or little, assessment and monitoring an audience must engage in. When it is understood in this way the debate simply ignores the relationship speaker and audience can have. Interlocutors rarely adopt the detached approach to communication implied by talk of assessment and monitoring. Audiences trust speakers to (...) be truthful and demonstrate certain reactive attitudes if they are not. Trust and the accompanying willingness to these reactive attitudes can then provide speakers with a reason to be trustworthy. So through ignoring interlocutors' engagement with the communicative process, the existing debate misses the possibility that it is an audience's trusting a speaker that makes it reasonable for the audience to accept what the speaker says.

In this paper, we develop a general normative framework for criticisability, blamelessness and blameworthiness in action. We then turn to the debate on norms of assertion. We show that an application of this framework enables champions of the so-called knowledge rule of assertion to offer a theoretically motivated response to a number of putative counterexamples in terms of blamelessness. Finally, we argue that, on closer inspection, the putative counterexamples serve to confirm the knowledge rule and disconfirm rival views.

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay (...) rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

In other work I have defended the claim that, when we rely on other speakers by accepting what they tell us, our reliance on them differs in epistemically relevant ways from our reliance on instruments, when we rely on them by accepting what they “tell” us. However, where I have explored the former sort of reliance at great length, I have not done so with the latter. In this paper my aim is to do so. My key notions will be (...) those of our social practices, the normative expectations that are sanctioned by those practices, and the epistemically engineered environments constituted by some of these practices. With these notions in mind, I will argue that one’s reliance on instruments, while relevantly different from one’s reliance on other speakers, can nevertheless manifest a kind of epistemic dependence which epistemological theory can and should acknowledge.

Can we gain understanding from testifiers who themselves fail to understand? At first glance, this looks counterintuitive. How could a hearer who has no understanding or very poor understanding of a certain subject matter non-accidentally extract items of information relevant to understanding from a speaker’s testimony if the speaker does not understand what she is talking about? This paper shows that, when there are theories or representational devices working as mediators, speakers can intentionally generate understanding in their hearers by engaging (...) in relevant speech acts without understanding the topic of these speech acts themselves. More specifically, I argue that testifiers can intentionally elicit understanding of empirical phenomena in their hearers even if they themselves lack such understanding – granted that they properly understood the epistemic mediators involved. (shrink)

One popular view in recent years takes the source of testimonial entitlement to reside in the intrinsically social character of testimonial exchanges. This paper looks at two extant incarnations of this view, what we dub ‘weak’ and ‘modest’ social anti-reductionism, and questions the rationales behind their central claims. Furthermore, we put forth an alternative, strong social anti-reductionist account, and show how it does better than the competition on both theoretical and empirical grounds.

According to the traditional philosophical definition, you lie if and only if you say something that you believe to be false and you intend to deceive someone into believing what you say. However, philosophers have recently noted the existence of bald-faced lies, lies which are not intended to deceive anyone into believing what is said. As a result, many philosophers have removed deception from their definitions of lying. According to Jennifer Lackey, this is ‘an unhappy divorce’ because it precludes an (...) obvious explanation of the prima facie wrongness of lying. Moreover, Lackey claims that there is a sense of deception in which all lies are deceptive. In this paper, I argue that bald-faced lies are not deceptive on any plausible notion of deception. In addition, I argue that divorcing deception from lying may not be as unhappy a result as Lackey suggests. (shrink)

In recent years, two competing methodological frameworks have developed in the study of the epistemology of philosophy. The traditional camp, led by experimental philosophy and its allies, has made inferences about the epistemology of philosophy based on the reactions, or intuitions, people have to works of philosophy. In contrast, multiple authors have followed the lead of Deutsch and Cappelen by setting aside experimental data in favor of inferences based on careful examination of the text of notable works of philosophy. In (...) other words, the debate is split between authors focusing on philosophy’sconsumptionand those focusing on philosophy’sproduction. This paper examines the motivation for focusing on original texts and other evidence of philosophy’s production and finds it lacking. Drawing upon Hills’ distinction between propagation and transmission, I argue that the social epistemology of philosophy does not justify the recent focus on original texts of philosophy. Because the philosophical knowledge of consumers of philosophy is likelyinspiredby producers of philosophy, as opposed to epistemically grounded in the producers’ epistemic states, experimental philosophy had it right all along—if we want to know the epistemic standing of philosophy, we need to look to philosophy’s consumers.

Skeptical theism is a family of responses to arguments from evil. One important member of that family is Stephen Wykstra’s CORNEA-based criticism of William Rowe’s arguments from evil. A cornerstone of Wykstra’s approach is his CORNEA principle. However, a number of authors have criticized CORNEA on various grounds, including that it has odd results, it cannot do the work it was meant to, and it problematically conflicts with the so-called common sense epistemology. In this paper, I explicate and defend a (...) CORNEA principle. After sketching a brief argument for it, I show how it can be acquitted of these recent charges. (shrink)

In philosophy, as in many other disciplines and domains, stable disagreement among peers is a widespread and well-known phenomenon. Our intuitions about paradigm cases, e.g. Christensen's Restaurant Case, suggest that in such controversies suspension of judgment is rationally required. This would prima facie suggest a robust suspension of judgment in philosophy. But we are still lacking a deeper theoretical explanation of why and under what conditions suspension is rationally mandatory. In the first part of this paper I will focus on (...) this question. After a critical survey of some recent alternative approaches (diversity as a thread to the reliability, decision problem, acquisition of undercutting defeaters), I will argue that in fact discovering disagreement with an opponent provides me with a rebutting defeater, but only if some further non-trivial conditions are satisfied - among them my acknowledging her as my reliability peer. In the second part of the paper I will explore in more detail the skeptical implications this account has for philosophy. Here, I will defend two claims. First, skepticism about philosophy is mandatory only if the relevant peerness assumption can be justified. Second, in philosophy there is no basis available that would support the relevant peerness assumption. If this is correct, we are not forced into skepticism about philosophy and may rationally retain our philosophical beliefs even in the face of controversy. (shrink)

In a number of recent papers Duncan Pritchard argues that virtue epistemology's central ability condition—one knows that p if and only if one has attained cognitive success (true belief) because of the exercise of intellectual ability—is neither necessary nor sufficient for knowledge. This paper discusses and dismisses a number of responses to Pritchard's objections and develops a new way of defending virtue epistemology against them.

This chapter states the contrast between presumptivism about testimonial warrant (often called anti-reductionism) and strict reductionism (associated with Hume) about testimonial warrant. Presumptivism sees an analogy with modest foundationalism about perceptual warrant. Strict reductionism denies this analogy. Two theoretical frameworks for these positions are introduced to better formulate the most popular version of persumptivism, a competence reliabilist account. Seven arguments against presumptivism are then stated and critiqued: (1) The argument from reliability; (2) The argument from reasons; (3) the argument from (...) positive reasons; (4) the argument from negative reasons; (5) the argument from agency; (6) the argument from psychological force; and (7) the argument from gullibility. If presumptivm is false, it is not for any of these arguments. (shrink)

A conspicuous oversight in recent debates about the vexed problem of the value of knowledge has been the value of knowledge-how. This would not be surprising if knowledge-how were, as Gilbert Ryle [1945, 1949] famously thought, fundamentally different from knowledge-that. However, reductive intellectualists [e.g. Stanley and Williamson 2001; Brogaard 2008, 2009, 2011; Stanley 2011a, 2011b] maintain that knowledge-how just is a kind of knowledge-that. Accordingly, reductive intellectualists must predict that the value problems facing propositional knowledge will equally apply to knowledge-how. (...) We show, however, that this is not the case. Accordingly, we highlight a value-driven argument for thinking that knowledge-how and knowledge-that come apart. (shrink)

We often prefer non-deferential belief to deferential belief. In the last twenty years, epistemology has seen a surge of sympathetic interest in testimony as a source of knowledge. We are urged to abandon ‘epistemic individualism’ and the ideal of the ‘autonomous knower’ in favour of ‘social epistemology’. In this connection, you might think that a preference for non-deferential belief is a manifestation of vicious individualism, egotism, or egoism. I shall call this the selfishness challenge to preferring non-deferential belief. The aim (...) of this paper is to meet the selfishness challenge by arguing that non-deferential belief is socially valuable. (shrink)

Users of sociotechnical systems often have no way to independently verify whether the system output which they use to make decisions is correct; they are epistemically dependent on the system. We argue that this leads to problems when the system is wrong, namely to bad decisions and violations of the norm of practical reasoning. To prevent this from occurring we suggest the implementation of defeaters: information that a system is unreliable in a specific case (undercutting defeat) or independent information that (...) the output is wrong (rebutting defeat). Practically, we suggest to design defeaters based on the different ways in which a system might produce erroneous outputs, and analyse this suggestion with a case study of the risk classification algorithm used by the Dutch tax agency.

Testimony is a vital and ubiquitous source of knowledge. Were we to refrain from accepting the testimony of others, our lives would be impoverished in startling and debilitating ways. Despite the vital role that testimony occupies in our epistemic lives, traditional epistemological theories have focused primarily on other sources, such as sense perception, memory, and reason, with relatively little attention devoted specifically to testimony. In recent years, however, the epistemic significance of testimony has been more fully appreciated. I shall here (...) focus on two questions that have received the most attention in recent work in the epistemology of testimony. First, is testimonial knowledge acquired only by being transmitted from speaker to hearer? Second, must a hearer have positive reasons to justifiedly accept a speaker's testimony? (shrink)

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

If I were to say, “Agnes does not know that it is raining, but it is,” this seems like a perfectly coherent way of describing Agnes’s epistemic position. If I were to add, “And I don’t know if it is, either,” this seems quite strange. In this chapter, we shall look at some statements that seem, in some sense, contradictory, even though it seems that these statements can express propositions that are contingently true or false. Moore thought it was paradoxical (...) that statements that can express true propositions or contingently false propositions should nevertheless seem absurd like this. If we can account for the absurdity, we shall solve Moore’s Paradox. In this chapter, we shall look at Moore’s proposals and more recent discussions of Moorean absurd thought and speech. (shrink)

Almost everyone agrees that many testimonial beliefs constitute knowledge. According to non-reductionists, some testimonial beliefs possess positive epistemic status independent of that conferred by perception, memory, and induction. Recently, Jennifer Lackey has provided a counterexample to a popular version of this view. Here I argue that her counterexample fails.

Cognitivism about trust says that it requires belief that the trusted is trustworthy; non-cognitivism denies this. At stake is how to make sense of the strong but competing intuitions that trust is an attitude that is evaluable both morally and rationally. In proposing that one's respect for another's agency may ground one's trusting beliefs, second-personal accounts provide a way to endorse both intuitions. They focus attention on the way that, in normal situations, it is the person whom I trust. My (...) task is to develop an account of the latter insight without the controversial theoretical commitments of the former. I propose a functional account for why the second and third-personal ‘systems’ operate not just in parallel, but in tandem, in support of a cognitivist account of trust. (shrink)

In this paper we address the question of how it can be possible for a non-expert to acquire justified true belief from expert testimony. We discuss reductionism and epistemic trust as theoretical approaches to answer this question and present a novel solution that avoids major problems of both theoretical options: Performative Expert Testimony (PET). PET draws on a functional account of expertise insofar as it takes the expert’s visibility as a good informant capable to satisfy informational needs as equally important (...) as her specific skills and knowledge. We explain how PET generates justification for testimonial belief, which is at once assessable for non-experts and maintains the division of epistemic labor between them and the experts. Thereafter we defend PET against two objections. First, we point out that the non-expert’s interest in acquiring widely assertable true beliefs and the expert’s interest in maintaining her status as a good informant counterbalances the relativist account of justification at work in PET. Second, we show that with regard to the interests at work in testimonial exchanges between experts and non-experts, PET yields a better explanation of knowledge-acquisition from expert testimony than externalist accounts of justification such as reliabilism. As our arguments ground in a conception of knowledge, which conceives of belief-justification as a declarative speech act, throughout the rearmost sections of this paper we also indicate to how such a conception is operationalized in PET.

Epistemic injustice consists in a wrong done to someone in their capacity as a knower. I focus on epistemic injustice—more specifically, testimonial injustice—as it arises in the Qur’an. Verse 2:282 implies that the worth of a man’s testimony is twice that of a woman’s testimony. The divine norm suggested by the verse is in direct conflict with the norms that govern testimonial justice. These norms require that women should not be judged less reliable simply because they are women. But a (...) divine norm that says that a woman’s testimony is worth less than a man’s also generates a puzzle for the norms that govern testimonial justice: when the divine norm that says that a woman’s testimony is worth half that of a man’s testimony is endorsed and internalised by Muslim women who then assert it, testimonial justice seems to require that we should take these women’s testimony to be less reliable than men’s testimony. I will argue that the solution to the puzzle lies in recognizing that the application of Quranic norms to a given situation requires getting some relevant facts right, and is not purely a matter of one’s values. As such, asserted Quranic norms are not subject to the deference characteristically demanded by testimonial justice. (shrink)

Influential cases have been provided that seem to suggest that one can fail to have knowledge because of the social environment. If not a distinct kind of social defeater, is there a uniquely social phenomenon that defeats knowledge? My aim in this paper is to explore these questions. I shall argue that despite initial appearances to the contrary, we have no reason to accept a special class of social defeater, nor any essentially social defeat phenomenon. We can explain putative cases (...) of social defeat with our existing epistemological apparatus. (shrink)

Two ideas shape the epistemology of testimony. One is that testimony provides a unique kind of knowledge. The other is that testimonial knowledge is a social achievement. In traditional terms, those who affirm these ideas are anti-reductionists, and those who deny them are reductionists. There is increasing interest, however, in the possibility of affirming these ideas without embracing anti-reductionism. Thus, Sanford Goldberg uses the idea of epistemic buck-passing to argue that even reductionists can accept the uniqueness of testimonial knowledge, and (...) Jennifer Lackey gives both speaker and hearer an essential role in testimonial justification, rejecting both reductionism and anti-reductionism in favor of what she calls dualism. After distinguishing a weaker and a stronger notion of buck-passing, we show how anti-reductionists can use the stronger notion to motivate their position, and to answer Goldberg’s and Lackey’s challenges.

In Chapter 3 of True Enough, Elgin outlines her view of objectual understanding, focusing largely on its non-factive nature and the extent to which a certain kind of know-how is required for the “grasping” component of understanding. I will explore four central issues that feature in this chapter, concentrating on the role of know-how, the concept of endorsement, Elgin’s critique of the factivity constraint on understanding, and how we might use aspects of Elgin’s framework to inform related debates on the (...) norm of assertion.

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

Stratified properties such as ‘happy unhappiness’, ‘ungrounded ground’, ‘fortunate misfortune’, and evidently ‘true falsity’ may generate dialetheias (true contradictions). The aim of the article is to show that if this is the case, then we will have a special, conjunctive, kind of dialetheia: a true state description of the form ‘Fa and not Fa’ (for some property F and object a), wherein the two conjuncts, separately taken, are to be held untrue. The particular focus of the article is on happy (...) unhappiness: people suffering from (or enjoying) happy unhappiness (if there is some situation or state of mind of this kind) cannot be truly said ‘happy’ or ‘unhappy’, but we can say they are both. In the first section three cases of conjunctive stratification are presented; in the second section the logic of stratified contradictions is explored. The last section focuses on eudemonistic ascriptions: stated that a is happy to be unhappy (or unhappy to be happy), should we say a is happy? unhappy? both? neither? (shrink)

Here are three (rough) theories of testimonial knowledge. (1) Speaker's knowledge: a hearer acquires the knowledge that P though testimony because of the speaker's knowledge that P--testimony "transfers" knowledge. This is the popular view, defended by Elizabeth Fricker and Paul Faulkner, among others. (2) Speaker's assertion: a hearer acquires the knowledge that P through testimony because the speaker's assertion that P is reliable that P in the right way (safe or sensitive). That's Jennifer Lackey's view. (3) Speaker's comprehension state: a (...) hearer acquired the knowledge that P through comprehending as of a speaker's assertion that P where the comprehension state is reliable in the right way (safe). That's my view. Lackey would reject such a view for it allows cases of testimonial knowledge that P from a speaker who did not assert that P. But Faulkner might reject Lackey's view on the grounds that it allows cases of testimonial knowledge that P from a speaker who did not know that P. Lackey replies that her account is better unified. But for the same reason, my account is even better unified. This paper runs through a series of cases and shows that my account--the Unified Account--is superior to the others. (shrink)

Jennifer Lackey argues that “testimony” in philosophy has one sense, but that sense—the concept expressed—is disjunctive. One disjunct she calls speaker-testimony and the other disjunct she calls hearer-testimony. A speaker then testifies simpliciter iff the speaker either speaker-testifies or hearer-testifies. Inadequate views of testimony, she argues, fail to recognize, distinguish and then disjoin these two “aspects” of testimony. I argue that her view about the semantics of “testimony” is mistaken and that her criticisms of two other views—mine included —are ineffective. (...) I argue that instead of one disjunctive concept, the word “testimony” expresses more than one concept; “testimony” means many things. In ordinary English, it names two distinct kinds of constative speech acts. In epistemology, it gets used a synonym for “assertion”. In epistemology, it also refers to the process whereby we form beliefs on the basis of comprehending assertions—to communication or interlocution. (shrink)

Epistemologists have recently started appealing to the moral philosophy literature on interpersonal trust in order to help explain the epistemology of testimony. We argue that epistemologists who have given trust a significant role in their accounts of the epistemology of testimony have appealed to very different conceptions of the nature of trust, which have inevitably influenced the shape of their epistemological theorizing. Some have employed accounts of the nature of interpersonal trust according to which trust is a practical phenomenon subject (...) to the will and to practical reasoning. Such accounts face the task of showing how the practical phenomenon that is interpersonal trust has epistemic implications for testimonial belief. Other theorists have employed accounts of the nature of interpersonal trust according to which trust is at least partly a cognitive phenomenon, itself subject to epistemic norms. Such accounts do not face the task of showing how practical rationality has implications for theoretical reason. Instead, they face the rather different tasks of showing how it is that cognitive trusting bears genuinely interpersonal features, and of how theoretical rationality can share features with practical rationality.

The central thesis of this paper is that fake news and related phenomena serve as defeaters for knowledge transmission via journalistic channels. This explains how they pose a threat to democracy; and it points the way to determining how to address this threat. Democracy is both intrinsically and instrumentally good provided the electorate has knowledge (however partial and distributed) of the common good and the means of achieving it. Since journalism provides such knowledge, those who value democracy have a reason (...) to protect it. Hostile agents, however, can undermine both the effectiveness of democratic decision-making and faith in democracy itself, by deliberately promulgating fake news and hyper-partisan views; moreover, these effects can come about unintentionally on social media. I conclude that we may need to change, not just the way we process information online, but also the informational environment in which we operate. (shrink)

This paper proposes a new externalist account of defeaters, in terms of reliable indicators, as an integral part of a unified externalist account of warrant and defeat. It is argued that posing externalist conditions on warrant, but internalist conditions on defeat lead to undesirable tensions. The proposal is contrasted to some rival accounts and then tested on some widely discussed cases, like the airport case. Misleading defeaters, where Laurence BonJour’s reliable clairvoyants serve as examples, also receive treatment, partly because they (...) illustrate how internalist constraints are inserted into the set up of the problem and therefore unduly constrain the domain of satisfactory solutions. Lastly, the proposal is defended against some objections. Firstly, that by posing externalist conditions on defeat, the account becomes too open. Secondly, that an externalist account fails to take into account the epistemic assessments of our fellows in the epistemic practice of forming beliefs and making epistemic claims, which can be based on accessible warrant only.

Recently, it has become popular to account for knowledge and other epistemic states in terms of epistemic virtues. The present paper focuses on an epistemic virtue relevant when deferring to others in testimonial contexts. It is argued that, while many virtue epistemologists will accept that epistemic virtue can be exhibited in cases involving epistemically motivated hearers, carefully vetting their testimonial sources for signs of untrustworthiness prior to deferring, anyone who accepts that also has to accept that an agent may exhibit (...) epistemic virtue in certain cases of blind deference, involving someone soaking up everything he or she is told without any hesitation. Moreover, in order to account for the kind of virtue involved in the relevant cases of blind deference, virtue epistemologists need to abandon a widespread commitment to personalism, i.e., the idea that virtue is possessed primarily on account of features internal to the psychology of the person, and accept that some virtues are social virtues, possessed in whole or in large part on account of the person being embedded in a reliable social environment.

Why do we trust TV news? What reasons might support a recipient’s assessment of the trustworthiness of this kind of information? This paper presents a veritistic analysis of the epistemic practice of news production and communication. The topic is approached by discussing a detailed case study, namely the characteristics of the most popular German news programme, called the ‘Tagesschau’. It will be shown that a veritistic analysis can indeed provide a recipient with relevant reasons to consider when pondering on the (...) trustworthiness of sources of information. Moreover, it will turn out that these reasons are part of what recipients might gather from media literacy. (shrink)

It has recently been argued that public linguistic norms are implicated in the epistemology of testimony by way of underwriting the reliability of language comprehension. This paper argues that linguistic normativity, as such, makes no explanatory contribution to the epistemology of testimony, but instead emerges naturally out of a collective effort to maintain language as a reliable medium for the dissemination of knowledge. Consequently, the epistemologies of testimony and language comprehension are deeply intertwined from the start, and there is no (...) room for grounding the one in terms of the other. (shrink)

Despite their substantial appeal, closure principles have fallen on hard times. Both anti-luck conditions on knowledge and the defeasibility of knowledge look to be in tension with natural ways of articulating single-premise closure principles. The project of this paper is to show that plausible theses in the epistemology of testimony face problems structurally identical to those faced by closure principles. First I show how Lasonen-Aarnio’s claim that there is a tension between single premise closure and anti-luck constraints on knowledge can (...) be extended to make trouble for transmission theses. Second, I show how Schechter’s claim that there is a tension between single premise closure and the thought that knowledge is defeasible can be extended to make trouble for transmission theses. I end the paper by sketching the consequences of this trouble for the dialectic in the epistemology of testimony. (shrink)

In this paper, I examine one central strand of Lackey’s The Epistemology of Groups, namely her account of group justified belief and the puzzle cases she uses to develop it. Her puzzle cases involve a group of museum guards most of whom justifiably believe a certain claim but do so on different bases. Consideration of these cases leads her to hold that a group justifiably believes p if and only if (1) a significant proportion of its operative members (a) justifiably (...) believe p on (b) bases that are consistent when combined and (2) the total evidence which members of the group do and should have had sufficiently support p. I question her judgement about these cases and condition 2, by examining the nature of group evidence as well as ‘transmission’ principles governing the relationship between the epistemic standing of members of a group and the group itself.

This paper argues that reading is a source of knowledge. Epistemologists have virtually ignored reading as a source of knowledge. This paper argues, first, that reading is not to be equated with attending to testimony, and second that it cannot be reduced to perception. Next an analysis of reading is offered and the source of knowledge that reading is further delineated. Finally it is argued that the source that reading is, can be both transmissive and generative, is non-basic, once was (...) a non-essential but has become essential for many people, and can be unique.

The crucial problem in the philosophy of psychiatry is to determine under which conditions certain behaviors, mental states, and personality traits should be regarded as symptoms of mental illnesses. Participants in the debate can be placed on a continuum of positions. On the one side of the continuum, there are naturalists who maintain that the concept of mental illness can be explained by relying on the conceptual apparatus of the natural sciences, such as biology and neuroscience. On the other side (...) of the continuum, there are normativists who maintain that the appropriate characterization of the concept of mental illness cannot avoid reference to epistemic, moral and other social values. Although, this article is primarily an introduction to the debate, we stress the importance of the normativist positions. (shrink)

Critical notice of Paul Faulkner, "Knowledge on Trust" (OUP 2011) and Benjamin McMyler, "Testimony, Trust, and Authority" (OUP 2011).

An influential view in the epistemology of testimony is that typical or paradigmatic beliefs formed through testimonial uptake are noninferential. Some epistemologists in particular defend a causal version of this view: that beliefs formed from testimony (BFT) are generated by noninferential processes. This view is implausible, however. It tends to be elaborated in terms that do not really bear it out – e.g. that BFT is fixed directly, immediately, unconsciously or automatically. Nor is causal noninferentialism regarding BFT plausibly expressed in (...) terms of belief-independent belief formation; the complex cognitive details of BFT fixation do not accord well with such a view. But perhaps the most significant issue is that the relevant causal notion of inference itself is not particularly well-defined, at least with respect to BFT. Causal noninferentialism in this domain is obscure as a result, but this does not in turn clearly vindicate any interesting version of inferentialism. (shrink)

This paper discusses the commitment account of assertion, according to which two necessary conditions for asserting that p are the speaker's undertaking a commitment to justify her assertion in the face of challenges and the speaker's licensing the audience to defer justificatory challenges back to her. Relying on what I call the "cancellation test," and focusing on Robert Brandom's version of the CAA, I show that the latter is wrong: it is perfectly possible to assert that p even while explicitly (...) disavowing the justificatory commitment and while refusing to issue a deferring license. Then I sketch an alternative to the CAA, the trust account of assertion, according to which speakers necessarily present themselves as trustworthy concerning p's truth whenever they assert p. I explain why this is different from undertaking a justificatory commitment, and offer some reasons for thinking that this is a more promising account. (shrink)

The simple knowledge norm of assertion holds that one may assert that p only if one knows that p. Turri :37–45, 2011) and Williamson both argue that more is required for epistemically permissible assertion. In particular, they both think that the asserter must assert on the basis of her knowledge. Turri calls this the express knowledge norm of assertion. I defend SKNA and argue against EKNA. First, I argue that EKNA faces counterexamples. Second, I argue that EKNA assumes an implausible (...) view of permissibility on which an assertion is epistemically permissible only if it is made for a right reason, i.e., a reason that contributes to making it the case that it is epistemically permissible to make that assertion. However, the analogous view in other normative domains is both controversial and implausible. This is because it doesn’t make it possible for one to act or react rightly for the wrong reason. I suggest that proponents of EKNA have conflated requirements for φ-ing rightly with requirements for φ-ing well. Finally, I argue that proponents of SKNA can explain the intuitive defectiveness of asserting on the basis of an epistemically bad reason, even when the asserters know the content of their assertion, by arguing that the asserters are epistemically blameworthy.

This article is an investigation into G. E. M. Anscombe's suggestion that there can be cases where belief takes a personal object, through an examination of the role that the activity of teaching plays in Anscombe's discussion. By contrasting various kinds of ‘teachers’ that feature in her discussion, it is argued that the best way of understanding the idea of believing someone personally is to situate the relevant encounter within the social, conversational framework of ‘engaged reasoning’.

Inference to the Best Explanation is usually employed in the Scientific Realism debates. As far as particular scientific theories are concerned, its most ready usage seems to be that of a theory of confirmation. There are however more uses of IBE, namely as an epistemological theory of testimony and as a means of categorising and justifying the sources of evidence. In this paper, I will present, develop and exemplify IBE as a theory of the quality of evidence - taking examples (...) from medicine and showing that IBE can thereby provide the epistemological underpinning and justify the criteria of grading quality of mechanistic evidence that have been recently provided in the Clarke et al. paper on how evidence of medical mechanisms is to be construed alongside population studies.
