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

Rules 405(a) and 608(a) of the Federal Rules of Evidence allow the use of testimony about a witness’s reputation to support or undermine his or her credibility in trial. This paper analyzes the evidential weight of such testimony from the point of view of social epistemology and the theory of social networks. Together they provide the necessary elements to analyze how reputation is understood in this case, and to assess the epistemic foundation of a reputational attribution. The result (...) of the analysis will be that reputational testimony is extremely weak from an epistemological point of view, and that in many cases there are more reliable substitutes that achieve a similar purpose. The obvious fix, in my view, is to eliminate the use of reputation testimony to support or undermine the credibility, honesty, chastity or peacefulness of a witness. (shrink)

Most traditional epistemologists see trust and knowledge as deeply antithetical: we cannot know by trusting in the opinions of others; knowledge must be based on evidence, not mere trust. I argue that this is badly mistaken. Modern knowers cannot be independent and self-reliant. In most disciplines, those who do not trust cannot know. Trust is thus often more epistemically basic than empirical evidence or logical argument, for the evidence and the argument are available only through trust. Finally, since the reliability (...) of testimonial evidence depends on the trustworthiness of the testifier, this implies that knowledge often rests on a foundation of ethics. The rationality of many of our beliefs depends not only on our own character, but on the character of others. (shrink)

We often learn the opinions of others without hearing the evidence on which they're based. The orthodox Bayesian response is to treat the reported opinion as evidence itself and update on it by conditionalizing. But sometimes this isn't feasible. In these situations, a simpler way of combining one's existing opinion with opinions reported by others would be useful, especially if it yields the same results as conditionalization. We will show that one method---upco, also known as multiplicative pooling---is specially (...) suited to this role when the opinions you wish to pool concern hypotheses about chances. The result has interesting consequences: it addresses the problem of disagreement between experts; and it sheds light on the social argument for the uniqueness thesis. (shrink)

The idea that fictions may educate us is an old one, as is the view that they distort the truth and mislead us. While there is a long tradition of passionate assertion in this debate, systematic arguments are a recent development, and the idea of empirically testing is particularly novel. Our aim in this chapter is to provide clarity about what is at stake in this debate, what the options are, and how empirical work does or might bear on its (...) resolution. We distinguish between merely influencing people’s opinions and providing genuine learning, where the latter requires that the source of the change in opinion should be reliable. Other important ideas here are the extent to which authors of fiction may be considered to provide testimony, or something like it, and the possibility of recognizing an unstated purpose in the project of the fictional work. We ask whether fictions can furnish us not merely with ideas but with reasons for believing them, perhaps by constituting thought experiments. We consider whether the focus should be on understanding rather than on knowledge, and whether fictions can inform us about the qualities of another’s experiences. We briefly describe some experimental work of recent decades and suggest that the evidence for learning from fiction is currently meagre. (shrink)

Computational models have shown how polarisation can rise among deliberating agents as they approximate epistemic rationality. This paper provides further support for the thesis that polarisation can rise under condition of epistemic rationality, but it does not depend on limitations that extant models rely on, such as memory restrictions or biased evaluation of other agents’ testimony. Instead, deliberation is modelled through agents’ purposeful introduction of arguments and their rational reactions to introductions of others. This process induces polarisation dynamics on (...) its own. A second result is that the effect size of polarisation dynamics correlates with particular types of argumentative behaviour. Polarisation effects can be soothed when agents take into account the opinions of others as premises, and they are amplified as agents fortify their own beliefs. These results underpin the relevance of argumentation as a factor in social-epistemic processes and indicate that rising issue polarisation is not a reliable indicator of epistemic shortcomings.

This paper presents a new solution to the problem of peer disagreement that distinguishes two principles of rational belief, here called probability and autonomy. When we discover that we disagree with peers, there is one sense in which we rationally ought to suspend belief, and another in which we rationally ought to retain our original belief. In the first sense, we aim to believe what is most probably true according to our total evidence, including testimony from peers and authorities. (...) In the second, we aim to base our beliefs only on objective evidence and argumentation, even if that lowers the probability of their being true. The first principle of rational belief tends to serve the short-term epistemic interests of individuals, while the second tends to serve the long-term epistemic interests of both individuals and groups. The best way to reconcile these principles in cases of peer disagreement is to associate them with two corresponding species of belief, here called perception and opinion. (shrink)

Decision-making typically requires judgments about causal relations: we need to know the causal effects of our actions and the causal relevance of various environmental factors. We investigate how several individuals' causal judgments can be aggregated into collective causal judgments. First, we consider the aggregation of causal judgments via the aggregation of probabilistic judgments, and identify the limitations of this approach. We then explore the possibility of aggregating causal judgments independently of probabilistic ones. Formally, we introduce the problem of causal-network aggregation. (...) Finally, we revisit the aggregation of probabilistic judgments when this is constrained by prior aggregation of qualitative causal judgments. (shrink)

Aἰών. Eternity in the Theology of Heraclitus of Ephesus -/- This article presents an attempt to establish the Heraclitean meaning of the word αἰών in the fragment B52 (Diels-Kranz). In the author’s view the very starting-point and only sound basis for that kind of endeavor should be meticulous, unbiased analysis of relevant aphorisms of the Ephesian sage and corresponding testimonies. Synoptic scrutiny of them substantiates the understandable conclusion that proud Heraclitus had an unambiguous and independent opinion about eternity. His (...) God – identified with the one and common world – is eternal not only in his „material” aspect as πῦρ ἀείζωον (‘an ever-living fire’, B30), but also in „rational” one as Λόγος ἐὼν ἀεί (‘Logos existing always’, B1). Consequently, one of his various names is Aἰών (‘He Who Always Is’). (shrink)

This paper presents the teaching of Isocrates (436-338 BC), Plato’s contemporary Athenian author, and his conceptions about the form and purposes of paideia or education, which he called, as a whole, philosophía. To this end, the list of students Isocrates supposedly had, the popularity of his school and the testimony by other authors of antiquity on his educational influence are described. After that, the isocratic definition of philosophía is discussed: sometimes presented as an intellectual commitment coupled with experience, at (...) other times as the culture or paideia created by Athens, a city where logos, in its double meaning of reason and discourse, occupied a place of exceptional importance. Finally, I move from this general definition of philosophía to that presented and professed by Isocrates in his school, which, according to him, was the only one to fully deserve the title of philosophía, defined as a deliberate educational procedure. Then the philosophía of Isocrates and its most important principles are presented: dóxa or opinion, empeíria or experience, and the kairós or occasion, pointing out the reasons for this option, the expected results of such educational program, and how such principles appear in what we would call its pedagogical methods, among which Isócrates’ practice of submitting his own works to the criticism of his students, in a form of discussion or debate that nowadays we would call a seminar, stands out. ********** O artigo apresenta o magistério de Isócrates (436-338 a.C.), autor ateniense contemporâneo de Platão, e suas concepções acerca da forma e dos propósitos da paideía ou educação, que ele denominava, em seu conjunto, philosophía. Para tanto, descrevemse o rol dos alunos que Isócrates teria tido, a popularidade de sua escola e o testemunho, por outros autores da Antiguidade, de sua influência educativa. Em seguida, discute-se a definição isocrática de philosophía, apresentada, por vezes, como um empenho intelectual conjugado à experiência; em outros momentos, como a cultura ou paideía criada por Atenas, cidade em que o lógos, em seu duplo sentido de razão e discurso, ocupava lugar de excepcional importância. Por fim, passa-se dessa definição geral de philosophía para aquela que a apresenta como um procedimento educativo deliberado, sendo que o professado por Isócrates em sua escola seria, segundo ele, o único a merecer, de todo direito, o título de philosophía. Descreve-se, então, a philosophía de Isócrates, com seus princípios mais importantes, a dóxa, ou opinião; a empeiría, ou experiência, e o kairós, ou ocasião, indicando as justificativas para essa opção e os resultados esperados de tal programa educativo, e de que modo tais princípios estariam presentes no que chamaríamos de seus métodos pedagógicos, dos quais se destaca a prática de Isócrates de submeter suas próprias obras à crítica de seus alunos, em um formato de discussão ou debate próximo do que denominaríamos, hoje, de seminário.

The original concept of epistemic dependence suggests uncritical deference to expert opinions for non-experts. In the light of recent work in science studies, however, the actual situation of epistemic dependence is seen to involve the necessary and ubiquitous need for lay evaluations of scientific experts. As expert knowledge means restricted cognitive access to some epistemic domain, lay evaluations of expert knowledge are rational and informed only when the criteria used by non-experts when judging experts are different from the criteria used (...) by experts when making their claims. The distinction between ‘substantial knowledge’ and ‘contextual knowledge’ allows for the laypeople to know with experts without having to know precisely what experts know. Such meta-expert evaluations are not specific to the public sphere outside science, nor are they limited internally to science, but they are present in a wide range of contexts in and around science. The paper legitimizes the concept of contextual knowledge by relating it to the relevant literature, and expounds the idea by identifying some elements of such a knowledge. (shrink)

Objective :This research aims at the constructing a basic perspective on critical thinking in line with Islamic principles with a brief explanation of such principles. Methodology :This study uses exegetical methods, by studying the relevant parts of the religious texts and systemizing the information in a critical way. Research findings: The research demonstrates that the principles for constructing an Islamic critical thinking perspective are found in the primary sources of Islam. The knowledge (العلم ;al-'ilm) makes the core of Islamic critical (...) thinking, and means of such knowledge are the revelation (الوحي; al-wahy), the use of senses (احلواس ;al-hawas), intellect (reason and heart, القلب و العقل ;al-aql wa al-qalb), historical experience or testimony (اوالشهادة السياحة ;al-siyahah aw al-shidah), and meditating on the natural and physical world (الكون ;al-kaun). There are other means such as prophetic dreams (الصادقة الرؤاي ;al-ruya al-sadiqah), insight (الفراسة ;al-firasah), illumination ( املكاشفة; al-mukashafah), and inspiration ( االهلام; al-ilham), though they are dismissed to account for any scholarly opinion or position and thus they remain non-binding according to Shariah. However, they can be a gift of a genius mind that is extraordinarily critical, helping such minds in understanding and creativity. Critical thinking includes using many human faculties and the Quran frequently emphasizes contemplation التفكر ;al-tafakur), reflection (التدبر ;at-tadabbur), understanding التفقه; at-tafaqquh), and reasoning (التعقل ;at-taakul); and these concepts are the foundations of critical thinking which could be developed and elaborated in many ways. Applications: The need of having an Islamic construction of critical thinking is because of the special worldview of Islam and its conception of knowledge which treats revelation (الوحي ;al-wahy) as the primary source of belief and knowledge. The findings of the study can be useful in fashioning a basic curriculum for critical thinking for Islamic educational institutions. (shrink)

In his questio on the motion of elements and mixed bodies in a void the Italian professor of practical medicine, Albertino Rinaldi da Salso di Piacenza (Albertinus de Rainaldis de Placentia, also known as Albertino da Piacenza), held the clearly non-Aristotelian view that an element in a void would not move instantaneously, but successively. To prove his conclusion Albertino draws to a large degree on arguments proposed by Richard Kilvington. Among the few 14th century authors who rejected Aristotle’s account of (...) motion in a vacuum Kilvington had presented the most thorough analysis of this subject. While Kilvington is known for his sophisticated argumentation and entangled style of presenting and sometimes nearly hiding his own opinions, Albertino’s treatise is better structured, and his conclusions are brought out more clearly. His disputation is an impressive testimony to the impact of Kilvington’s views of motion in a void. (shrink)

There are different ways to study feminism. One of the ways is to study it by analyzing the waves of feminism. Though there are differences of opinion on how many waves of feminism have been so far, we would like to hold on to the generally accepted view that there are four waves of feminism so far and we try to research into one of the hallmarks of the fourth wave feminism, feminist hashtag. Though some people consider hashtags momentary (...) and frenzy, it’s a platform for feminist epistemology and feminist policy making. Moreover, it assists the development of social epistemology and reconsiders the notion of objectivity. The representative slogans of the first three waves of feminism were like the precursors of hashtags and the spokeswomen of the first three waves of feminism present the necessity of space for writing. The fourth-wave feminists make use of cyberspace as a space for addressing feminist concerns through hashtags. However, we recognize certain similarities of concerns in all the waves of feminism. The analysis of two epistemological theses, i.e., situated knowledge thesis and epistemic advantage thesis on developing the theme of how hashtags assist in knowledge production. The idea of situated knowledge explains how experiences specific to oppressed members of groups can serve as the basis of the development of important insights. Hashtags could be considered as a new way of understanding the links between gender and knowledge. Feminist slogans and hashtags are also media of testimonial exchange. When the issues of differential credulity and credibility arise the tenet of situated knowing comes to the aid of the feminist thinker. Building up the climate of trust generates knowledge of the forces and dynamics of the oppressed. Trust helps to overcome identity prejudice and testimonial injustice. Feminist policies make women visible in feminist public policies. Responsible interventions into epistemic practices by public policy-making can help move society in the direction of social justice. Hashtag testimony leads to consciousness-raising and protest movements which in turn leads to the public reasoning and policy that empowers women. The reflections of Miranda Fricker are of great advantage in disclosing feminist epistemology that revolves around feminist hashtags. Her doctrines enrich the feminist hashtags with new insights and new directions. A study on the epistemological relevance of hashtag feminism enhances the development of social epistemology. It invites our attention to re-reflect on the concept of objectivity and empowers feminist movements and women. (shrink)

Suppose several individuals (e.g., experts on a panel) each assign probabilities to some events. How can these individual probability assignments be aggregated into a single collective probability assignment? This article reviews several proposed solutions to this problem. We focus on three salient proposals: linear pooling (the weighted or unweighted linear averaging of probabilities), geometric pooling (the weighted or unweighted geometric averaging of probabilities), and multiplicative pooling (where probabilities are multiplied rather than averaged). We present axiomatic characterisations of each class of (...) pooling functions (most of them classic, but one new) and argue that linear pooling can be justified procedurally, but not epistemically, while the other two pooling methods can be justified epistemically. The choice between them, in turn, depends on whether the individuals' probability assignments are based on shared information or on private information. We conclude by mentioning a number of other pooling methods. (shrink)

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

In the epistemology of testimony it is often assumed that audiences are able to reliably recover asserted contents. In the philosophy of language this claim is contentious. This paper outlines one problem concerning the recovery of asserted contents, and argues that it prevents audiences from gaining testimonial knowledge in a range of cases. The recovery problem, in essence, is simply that due to the collective epistemic limitations of the speaker and audience speakers will, in certain cases, be insensitive to (...) the ways in which they may be misinterpreted. As a result audiences’ beliefs will often fail the safety and sensitivity conditions on knowledge. Once the problem has been outlined and distinguished from several related problems in the philosophy of language and the epistemology of testimony, a series of responses are considered. The first response holds that audiences possess defeaters in recovery problem cases, and thus wouldn’t form beliefs. The second response holds that the beliefs audiences form are very coarse grained, meaning they are not very vulnerable to failures of safety and sensitivity. The final response holds that the objects of speaker meaning are not propositional. All three responses are found to be unsatisfactory. (shrink)

This paper identifies two distinct dimensions of what might be called testimonial strength: first, in the case of testimony from more than one speaker, testimony can be said to be stronger to the extent that a greater proportion of the speakers give identical testimony; second, in both single-speaker and multi-speaker testimony, testimony can be said to the stronger to the extent that each speaker expresses greater conviction in the relevant proposition. These two notions of testimonial (...) strength have received scant attention in the philosophical literature so far, presumably because it has been thought that whatever lessons we learn from thinking about testimony as a binary phenomenon will apply mutatis mutandis to varying strengths of testimony. This paper shows that this will not work for either of the two aforementioned dimensions of testimonial strength, roughly because less testimony can provide more justification in a way that can only be explained by appealing to the (non-binary) strength of the testimony itself. The paper also argues that this result undermines some influential versions of non-reductionism about testimonial justification. (shrink)

Epistemologists typically assume that the acquisition of knowledge from testimony is not threatened at the stage at which audiences interpret what proposition a speaker has asserted. Attention is instead typically paid to the epistemic status of a belief formed on the basis of testimony that it is assumed has the same content as the speaker’s assertion. Andrew Peet has pioneered an account of how linguistic context sensitivity can threaten the assumption. His account locates the threat in contexts in (...) which an audience’s evidence under-determines which proposition a speaker is asserting. I argue that Peet’s epistemic uncertainty account of the threat is mistaken and I propose an alternative. The alternative locates the threat in contexts that provide factors that give audiences a mistaken psychological certainty or confidence that a speaker has asserted a proposition she has not.

Can we transmit understanding via testimony in more or less the same way in which we transmit knowledge? The standard view in social epistemology has a straightforward answer: no, we cannot. Three arguments supporting the standard view have been formulated so far. The first appeals to the claim that gaining understanding requires a greater cognitive effort than acquiring testimonial knowledge does. The second appeals to a certain type of epistemic trust that is supposedly characteristic of knowledge transmission (and maybe (...) of the transmission of epistemic goods in general) and that is allegedly incompatible with understanding. The third aims to show that there is a certain aspect of understanding (what epistemologists these days like to call “grasping”) that cannot be passed on to another person via testimony alone. In this article, I show that all of these arguments can be resisted. Thus, there seem to be no compelling reasons to embrace the standard view. (shrink)

I outline what I call the ‘deniability problem’, explain why it is problematic, and identify the range of utterances to which it applies (using religious discourse as an example). The problem is as follows: To assign content to many utterances audiences must rely on their contextual knowledge. This generates a lot of scope for error. Thus, speakers are able to make assertions and deny responsibility for the proposition asserted, claiming that the audience made a mistake. I outline the problem (a (...) limited version of which Fricker 2012 discusses), before explaining why it is problematic. Firstly it blocks testimonial knowledge according to assurance views. Secondly it prevents epistemic buck passing (the importance of which is emphasized by Goldberg 2006 and McMyler 2013). Finally, it removes a key disincentive to dishonesty. The recent literature on context sensitivity (particularly Cappelen and Lepore 2004) seems to entail that the problem applies to a very wide range of utterances. I consider a series of responses which fail to provide a solution, but which help us narrow down the scope of the problem. (shrink)

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.

That testimony is one of the principle bases on which many people hold their religious beliefs is hard to dispute. Equally hard to dispute is that our world contains an array of mutually incompatible religious traditions each of which has been transmitted down the centuries chiefly by way of testimony. In light of this latter it is quite natural to think that there is something defective about holding religious beliefs primarily or solely on the basis of testimony (...) from a particular tradition. The present chapter takes up the question of what that defect consists in. I first consider whether religious diversity entails that a religious believer’s testimony-based beliefs are not formed in a suitably epistemically reliable manner even conditional upon the truth of her religion. After casting doubt on this thought I turn to look at the idea that testimony-based beliefs are subject to defeaters in light of awareness of religious diversity, and I suggest that many such beliefs are not obviously so. According to my diagnosis the problem, rather, is that believers who base their religious beliefs just on testimony will be very unlikely to have reflective (that is, second-order) knowledge even if they possess first-order knowledge, and I explain why this is a notable shortcoming. (shrink)

I argue, first, that testimony is likely a natural kind (where natural kinds are accurately described by the homoeostatic property cluster theory) and that if it is indeed a natural kind, it is likely necessarily reliable. I argue, second, that the view of testimony as a natural kind and as necessarily reliable grounds a novel, naturalist global reductionism about testimonial justification and that this new reductionism is immune to a powerful objection to orthodox Humean global reductionism, the objection (...) from the too-narrow induction base.

This article discusses the following question: what epistemic relation must audiences bear to the content of assertions in order to gain testimonial knowledge? There is a brief discussion of why this issue is of importance, followed by two counterexamples to the most intuitive answer: that in order for an audience to gain testimonial knowledge that p they must know that the speaker has asserted p. It is then suggested that the argument generalises and can be made to work on different (...) sets of assumptions about the conditions for knowledge, and the conditions under which a proposition is asserted.

Jennifer Lackey’s case “Creationist Teacher,” in which students acquire knowledge of evolutionary theory from a teacher who does not herself believe the theory, has been discussed widely as a counterexample to so-called transmission theories of testimonial knowledge and justification. The case purports to show that a speaker need not herself have knowledge or justification in order to enable listeners to acquire knowledge or justification from her assertion. The original case has been criticized on the ground that it does not really (...) refute the transmission theory, because there is still somebody in a chain of testifiers—the person from whom the creationist teacher acquired what she testifies—who knows the truth of the testified statements. In this paper, we provide a kind of pattern for generating counterexample cases, one that avoids objections discussed by Peter Graham and others in relation to such cases. (shrink)

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

Jennifer Lackey ('Testimonial Knowledge and Transmission' The Philosophical Quarterly 1999) and Peter Graham ('Conveying Information, Synthese 2000, 'Transferring Knowledge' Nous 2000) offered counterexamples to show that a hearer can acquire knowledge that P from a speaker who asserts that P, but the speaker does not know that P. These examples suggest testimony can generate knowledge. The showpiece of Lackey's examples is the Schoolteacher case. This paper shows that Lackey's case does not undermine the orthodox view that testimony cannot (...) generate knowledge. This paper explains why Lackey's arguments to the contrary are ineffective for they misunderstand the intuitive rationale for the view that testimony cannot generate knowledge. This paper then elaborates on a version of the case from Graham's paper 'Conveying Information' (the Fossil case) that effectively shows that testimony can generate knowledge. This paper then provides a deeper informative explanation for how it is that testimony transfers knowledge, and why there should be cases where testimony generates knowledge. (shrink)

To verify the occurrence of a singular instance of testimonial injustice three facts must be established. The first is whether the hearer in fact has an identity prejudice of which she may or may not be aware; the second is whether that prejudice was in fact the cause of the unjustified credibility deficit; and the third is whether there was in fact a credibility deficit in the testimonial exchange. These three elements constitute the facts of the matter of testimonial injustice. (...) In this essay we argue that none of these facts can be established with any degree of confidence, and therefore that testimonial injustice is an undetectable phenomenon in singular instances. Our intention is not to undermine the idea of testimonial injustice, but rather to set limits to what can be justifiably asserted about it. According to our argument, although there are insufficient reasons to identify individual acts of testimonial injustice, it is possible to recognize recurrent patterns of epistemic responses to speakers who belong to specific social groups. General testimonial injustice can thus be characterized as a behavioral tendency of a prejudiced hearer. (shrink)

There is an emerging skepticism about the existence of testimonial knowledge-how :387–404, 2010; Poston in Noûs 50:865–878, 2016; Carter and Pritchard in Philos Phenomenol Res 91:181–199, 2015a). This is unsurprising since a number of influential approaches to knowledge-how struggle to accommodate testimonial knowledge-how. Nonetheless, this scepticism is misguided. This paper establishes that there are cases of easy testimonial knowledge-how. It is structured as follows: first, a case is presented in which an agent acquires knowledge-how simply by accepting a speaker’s (...) class='Hi'>testimony. Second, it is argued that this knowledge-how is genuinely testimonial. Next, Poston’s arguments against easy testimonial knowledge-how are considered and rejected. The implications of the argument differ for intellectualists and anti-intellectualists about knowledge-how. The intellectualist must reject widespread assumptions about the communicative preconditions for the acquisition of testimonial knowledge. The anti-intellectualist must find a way of accommodating the dependence of knowledge-how on speaker reliability. It is not clear how this can be done. (shrink)

In this paper I defend the claim that testimony can serve as a basic source of knowledge of other people’s mental lives against the objection that testimonial knowledge presupposes knowledge of other people’s mental lives and therefore can’t be used to explain it.

It is sometimes claimed that faith is a virtue. To what extent faith is a virtue depends on what faith is. One construal of faith, which has been popular in both recent and historical work on faith, is that faith is a matter of taking oneself to have been spoken to by God and of trusting this purported divine testimony. In this paper, I argue that when faith is understood in this way, for faith to be virtuous then it (...) must be accompanied by intellectual humility. I defend this view by showing how someone ought to respond to purported divine testimony if her faith is to be intellectually humble, and how, if it fails in this respect, it will instead be accompanied by the vices of either servility or arrogance.

It is generally acknowledged that testifiers can play a central role in the production of knowledge and other valuable epistemic states in others. But does such a role warrant any form of epistemic credit and is an agent more successful qua epistemic agent insofar as she is a successful testifier? I here propose an affirmative answer to both questions. The core of the current paper consists in a sustained defence of this proposal against a series of objections. I further argue (...) that the proposal allows us to recognize an important additional epistemic harm that arises in cases of testimonial injustice beyond those described by Miranda Fricker. Finally, I conclude by distinguishing between four kinds of credit - distinctions that allow us to avoid inappropriately attributing epistemic credit in problematic cases. If the current proposal is correct, our understanding of successful epistemic agents needs to be significantly modified in order to take into account their role in producing epistemically valuable states in others.

Relying on aesthetic testimony seems problematic. For instance, it seems problematic for me to simply believe or assert that The Velvet Underground's debut album The Velvet Underground and Nico (1964) is amazing solely because you have told me so, even though I know you to be an honest and competent music critic. But why? After all, there do not seem to be similar reservations regarding testimony from many other domains. In this paper, I will argue that relying on (...) aesthetic testimony seems problematic because we are attached to an ideal of aesthetic authenticity and feel that living up to this ideal is anathema to simply relying on aesthetic testimony.

I present a puzzle – the “puzzle of aesthetic testimony” – along with a solution to it that appeals to the impossibility of testimonial understanding. I'll criticize this solution by defending the possibility of testimonial understanding, including testimonial aesthetic understanding.

According to telling based views of testimony (TBVs), B has reason to believe that p when A tells B that p because A thereby takes public responsibility for B's subsequent belief that p. Andrew Peet presents a new argument against TBVs. He argues that insofar as A uses context-sensitive expressions to express p, A doesn't take public responsibility for B's belief that p. Since context-sensitivity is widespread, the kind of reason TBVs say we have to believe what we're told, (...) is not widespread. Peet doesn't identify any problem with his own argument though he does attempt to limit its sceptical potential by identifying special contexts in which TBVs stand a chance of success. A more general defence of TBVs can be provided by showing Peet's argument to be unsound. I argue that Peet's argument is unsound because it requires us to wrongly suppose that speakers do far less labour than their audiences in context-sensitive linguistic communication. I aim to show why—in the context of the epistemology of testimony and the philosophy of language—it's important to recognize the labour that speakers can do, and so can can be held responsible for not doing, in episodes of context-sensitive linguistic communication.

I propose a new account of the limits of aesthetic testimony. One of this new account's main claims is that, among the kinds of aesthetic cognitive achievements, it is useful to distinguish aesthetic understanding. In particular, I suggest that the aesthetic understanding of X involves an understanding of why X is aesthetically valuable. In turn, aesthetic understanding is essentially connected to the deployment of aesthetic concepts.

A number of philosophers, from Thomas Reid1 through C. A. J. Coady2, have argued that one is justified in relying on the testimony of others, and furthermore, that this should be taken as a basic epistemic presumption. If such a general presumption were not ultimately dependent on evidence for the reliability of other people, the ground for this presumption would be a priori. Such a presumption would then have a status like that which Roderick Chisholm claims for the epistemic (...) principle that we are justified in believing what our senses tell us. (shrink)

Domestic violence and abuse (DVA) are at last coming to be recognised as serious global public health problems. Nevertheless, many women with personal histories of DVA decline to disclose them to healthcare practitioners. In the health sciences, recent empirical work has identified many factors that impede DVA disclosure, known as barriers to disclosure. Drawing on recent work in social epistemology on testimonial silencing, we might wonder why so many people withhold their testimony and whether there is some kind of (...) epistemic injustice afoot here. In this paper, I offer some philosophical reflections on DVA disclosure in clinical contexts and the associated barriers to disclosure. I argue that women with personal histories of DVA are vulnerable to a certain form of testimonial injustice in clinical contexts, namely, testimonial smothering, and that this may help to explain why they withhold that testimony. It is my contention that this can help explain the low rates of DVA disclosure by patients to healthcare practitioners. (shrink)

The literature on epistemic injustice has thus far confined the concept of testimonial injustice to speech expressions such as inquiring, discussing, deliberating, and, above all, telling. I propose that it is time to broaden the horizons of testimonial injustice to include a wider range of expressions. Controversially, the form of communication I have in mind is non-verbal expression. Non-verbal expression is a vital, though often overlooked, form of communication, particularly for people who have certain neurocognitive disorders. Dependency upon non-verbal expression (...) is a common feature of some forms of neurocognitive disorders such as ‘intellectual disabilities’, autism and late-stage dementia. According to the narrow definition of testimonial injustice currently championed in the literature, people who express non-verbally are exempt from testimonial injustice. However, when we consider cases where meaningful communications from non-verbal people are dismissed or ignored in virtue of identity prejudice, there seems to be a distinct testimonial harm at play. Using late-stage dementia as a case study, I argue that the definition of testimonial injustice should be expanded to include all communicative practices, whether verbal or non-verbal, to encompass the epistemic harms inflicted upon some of the most marginalised in our society.

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)

I argue for the Cooperative Warrant Thesis (CWT), according to which the determinants of testimonial contents in communication are given by the practical requirements of cooperative action. This thesis distances itself from conventionalist views, according to which testimony must be strictly bounded by conventions of speech. CWT proves explanatorily better than conventionalism on several accounts. It offers a principled and accurate criterion to distinguish between testimonial and non-testimonial communication. In being goal-sensitive, this criterion captures the role of weak and (...) robust cooperation in determining the contents to which speakers testify or fail to testify. And, finally, it yields a principled explanation of why testimony entails the epistemic commitments that distinguish it as an epistemic source. (shrink)

This article examines the meaningful intervention that Gert-Jan Van der Heiden’s recent book, The Voice of Misery: A Continental Philosophy of Testimony, makes in the developing field of the philosophy of testimony. I argue that this intervention is accomplished through a phenomenological investigation into the nature of the testimonial object and of the demand that it makes upon one who bears witness. In taking such an approach, I argue, Van der Heiden initiates an ontological turn in the field (...) of testimonial theory, shifting the conversation away from a debate about the conditions in which belief in testimony is justified – a debate that has in many ways defined the field for philosophers in the Anglo-American tradition. I suggest that Van der Heiden’s account is helpful in demonstrating that, in many cases, doing justice to a testimonial object requires an epistemic-ethical attitude other than belief. The article concludes by developing a few questions for Van der Heiden based on my interpretation of his project, including to what extent his phenomenology of testimony can account for how often our receptivity to testimony depends on the default trust that we have in others by virtue of our fundamental immersion in social life.

This chapter explores two kinds of testimonial trust, what we call ‘evidential trust’ and ‘non-evidential trust’ with the aim of asking how testimonial trust could provide epistemic reasons for belief. We argue that neither evidential nor non-evidential trust can play a distinctive role in providing evidential reasons for belief, but we tentatively propose that non-evidential trust can in some circumstances provide a novel kind of epistemic reason for belief, a reason of epistemic facilitation. The chapter begins with an extensive discussion (...) of standard accounts of both kinds of trust and criticises especially the standard accounts of non-evidential trust. A new account of non-evidential trust is offered that avoids a number of difficulties that plague the standard accounts by rejecting what we call ‘attitude-liability assumptions’. (shrink)

When you don’t believe a speaker’s testimony for reasons that call into question the speaker’s credibility, it seems that this is an insult against the speaker. There also appears to be moral reasons that count in favour of refraining from insulting someone. When taken together, these two plausible claims entail that we have a moral reason to refrain from insulting speakers with our lack of belief, and hence, sometimes, a moral reason to believe the testimony of speakers. Reasons (...) for belief arising from non-epistemic sources are controversial, and it’s often argued that it’s impossible to base a belief on non-epistemic reasons. However, I will show that even if it is possible to base a belief on non-epistemic reasons, in the case of testimonial insult, for many or most cases, the moral reasons for belief don’t need to be the basis of our doxastic response. This is because there are, in many or most cases, either sufficient epistemic reasons for belief, or sufficient moral reasons for action that guide our response to testimony. Reasons from testimonial insult, in many cases, simply lead to overdetermination. Even if there are such moral reasons for belief, they are therefore practically unnecessary in many cases. There are, though, some cases in which they play an important role in guiding belief. This perhaps surprising conclusion is one unexplored way to defend epistemic over pragmatic reasons for belief.

This paper argues for the general proper functionalist view that epistemic warrant consists in the normal functioning of the belief-forming process when the process has forming true beliefs reliably as an etiological function. Such a process is reliable in normal conditions when functioning normally. This paper applies this view to so-called testimony-based beliefs. It argues that when a hearer forms a comprehension-based belief that P (a belief based on taking another to have asserted that P) through the exercise of (...) a reliable competence to comprehend and filter assertive speech acts, then the hearer's belief is prima facie warranted. The paper discusses the psychology of comprehension, the function of assertion, and the evolution of filtering mechanisms, especially coherence checking. (shrink)

This paper introduces and argues for the hypothesis that judgments of testimonial worth are central to our practice of normatively appraising speech. It is argued that judgments of testimonial worth are central both to the judgement that an agent has lied, and to the acceptance of testimony. The hypothesis that, in lying, an agent necessarily displays poor testimonial worth, is shown to resolve a new puzzle about lying, and the recalcitrant problem raised by the existence of bald faced lies, (...) and selfless assertions. It is then shown that the notion of testimonial worth allows us to capture the distinction between taking a speaker at their word, and treating them as a mere indicator of the truth in a way other theories fail to do.
