Radical self-silencing is a particular variety of speech act disablement where the subject silences themselves, whether knowingly or not, because of their own faults or deficiencies. The paper starts with some concrete cases and preparatory comments to help orient and motivate the investigation. It then offers a summary analysis, drawing on a small number of basic concepts to identify its five individually necessary and jointly sufficient conditions and discriminating their two basic forms, ‘internalist’ and ‘externalist’. The paper then explicates and (...) defends what has been proposed, where the most salient and pressing objections concern the use of two basic concepts: ‘uptake’ and ‘silencing’. Finally, the paper gives a longer-term motivation for deepening our understanding of radical self-silencing, what it is and what it implies. (shrink)

Given that conspiracies exist, can we be justified in dismissing conspiracy theories without concerning ourselves with specific details? I answer this question by focusing on contrarian conspiracy theories, theories about conspiracies that conflict with testimony from reliable sources of information. For example, theories that say the CIA masterminded the assassination of John F. Kennedy, 9/11 was an inside job, or the Freemasons are secretly running the world are contrarian conspiracy theories. When someone argues for a contrarian conspiracy theory, their options (...) are to appeal to eyewitness testimony, incriminating documents, photographs, audio recordings, video recordings, allegedly scientific evidence, anomalies, or considerations of cui bono (who benefits). Most laypeople don’t know how to adequately respond to arguments for contrarian conspiracy theories, but this doesn’t mean that it’s dogmatic to reject them. I argue that many laypeople are defeasibly justified in rejecting a variety of contrarian conspiracy theories based on testimony and this justification is rarely defeated by arguments for contrarian conspiracy theories even if we don’t know how to respond to these arguments.

The thesis of this paper is that, if it is construed individualistically, epistemic justification does not capture the conditions that philosophers of science would impose on justified belief in a scientific hypothesis. The difficulty arises from beliefs acquired through testimony. From this I derive a lesson that epistemologists generally, and epistemologists of testimony in particular, should learn from philosophers of science: we ought to repudiate epistemic individualism and move towards a more fully social epistemology.

People have become suspicious of authority, including epistemic authorities, i.e., knowledge experts, even on matters individuals are unqualified to adjudicate. This is problematic since most of our knowledge comes from trusting a speaker—whether scholars reading experts, students listening to teachers, children obeying their parents, or pedestrians inquiring of strangers—such that the knowledge transmitted is rarely personally verified. Despite the recent development of social epistemology and theories of testimony, this is not a new problem. Ancient and Medieval philosophers largely took it (...) for granted that most human knowledge primarily comes from listening to a trustworthy speaker whose virtuous character serves to mitigate against the twin concerns of inaccuracy and dishonesty. Thus, unlike contemporary Social Epistemology, few testimonial theories were explicitly laid out despite the crucial role testimony plays throughout a wide range of topics and teachings. To date, the working theory of testimony underpinning the works of medieval philosophers are just now being codified. This is particularly relevant for the Abrahamic faiths since they originate with testimony from God himself. The goal of this dissertation is to explore how the generation and transmission of religious knowledge appears in an exemplary thinker from each faith: Saadya Gaon of Judaism, al-Ghazālī of Islam, and Thomas Aquinas of Christianity. While not contemporaries, these exemplars are theological philosophers who are like-minded in their desire to maintain an orthodox faith while possessing philosophical approaches to truth. Thus, they maintained sophisticated epistemological theories of generation and transmission within their own religious contexts. Cataloguing these medieval testimonial theories reveals a historical incongruity with the current contemporary concept of testimony and its frameworks. Based on the testimonial theories of these three thinkers, I argue for a "transhistorical" concept of testimony that does not presume an evidentialist framework to account for pre-modern theories of testimony which predominantly rely on virtue theoretic frameworks. To test the proposed neutral framework, I offer a virtue epistemological account of testimony in which trust is not an intellectual virtue, but the intellectual aspect of the historic virtue of autonomy. I argue that intellectual autonomy and trust are inversely related in one's interactions with authority. (shrink)

Explaining phenomena is a primary goal of science. Consequently, it is unsurprising that gaining a proper understanding of the nature of explanation is an important goal of science education. In order to properly understand explanation, however, it is not enough to simply consider theories of the nature of explanation. Properly understanding explanation requires grasping the relation between explanation and understanding, as well as how explanations can lead to scientific knowledge. This article examines the nature of explanation, its relation to understanding, (...) and how explanations are used to generate scientific knowledge via inferences to the best explanation. Studying these features and applications of explanation not only provides insight into a concept that is important for science education in its own right, but also sheds light on an aspect of recent debates concerning the so-called consensus view of nature of science (NOS). Once the relation between explanation, understanding, and knowledge is clear, it becomes apparent that science is unified in important ways. Seeing this unification provides some support for thinking that there are general features of NOS of the sort proposed by the consensus view and that teaching about these general features of NOS should be a goal of science education.

In this paper, I explore whether there is a need for a multiplicity of norms governing belief due to differences in the objects of those beliefs, particularly the difference between persons and nonpersons. I call the view according to which there is a single epistemic norm governing belief monism, and the view that there is more than one such norm pluralism. I consider three different kinds of objections to monism that stem specifically from considerations unique to assessing the credibility of (...) persons, along with corresponding pluralist proposals. I argue not only that all of the criticisms of monism fail, but also that the proposed pluralist norms face significant problems of their own. In so doing, the aim of the paper is to clear the path for there being a single epistemic norm governing belief, despite there being important epistemic differences between how we ought to treat persons and nonpersons.

This paper investigates whether practical interests affect knowledge attributions in cases of testimony. It is argued that stakes impact testimonial knowledge attributions by increasing or decreasing the requirements for hearers to trust speakers and thereby gain the epistemic right to acquire knowledge via testimony. Standard, i.e. invariantist, reductionism and non-reductionism fail to provide a plausible account of testimony that is stakes sensitive, while non- invariantist versions of both traditional accounts can remedy this deficiency. Support for this conceptual analysis of stakes (...) is found through a review of the experimental philosophy literature on stakes effects on knowledge attribution. Finally, a diagnosis is offered for what is needed to provide a more robust defense of the paper’s primary claims in terms of future experimental study. (shrink)

This paper develops a descriptive and normative account of how people respond to testimony. It postulates a default pathway in which people more or less automatically respond to a claim by accepting it, as long as the claim made is consistent with their beliefs and the source is credible. Otherwise, people enter a reflective pathway in which they evaluate the claim based on its explanatory coherence with everything else they believe. Computer simulations show how explanatory coherence can be maximized in (...) real-life cases, taking into account all the relevant evidence including the credibility of whoever is making a claim. The explanatory-coherence account is more plausible both descriptively and normatively than a Bayesian account. (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 surveys recent work on moral expertise. Much of that work defends an asymmetry thesis according to which the cognitive deference to expertise that characterizes other areas of inquiry is out of place in morality. There are two reasons why you might think asymmetry holds. The problem might lie in the existence of expertise or in deferring to it. We argue that both types of arguments for asymmetry fail. They appear to be stronger than they are because of their (...) focus on moral expertise regarding all-in judgments about rightness. We reject this emphasis on all-in judgment in favor of an account of moral expertise as typically multi-stranded and domain limited. This account of moral expertise is better able to address the problem of how to identify those who have expertise. It also offers a more nuanced picture of the contrast between accepting a moral claim on one's own and accepting it on testimony. (shrink)

This paper objects to internalist theories of justification from testimony on the grounds that they can’t accommodate intuitions about a pair of cases. The pair of cases involved is a testimonial version of the cases involved in the New Evil Demon Argument. The role of New Evil Demon cases in motivating contemporary internalist theories of knowledge and justification notwithstanding, it is argued here that testimonial cases make an intuitive case against internalist theories of justification from testimony.

Until recently, epistemology was largely caught in the grips of an epistemically unrealistic radical epistemological individualism on which the beliefs and testimony of others were of virtually no epistemic significance. Thankfully, epistemologists have bucked the individualist trend, acknowledging that one person's belief or testimony that P might offer another person prima facie epistemic reasons – or social evidence as I call it – to believe P. In this paper, I discuss the possibility and conditions under which beliefs and testimony act (...) as social evidence, in particular, beliefs and testimony regarding the existence of God. The epistemic egoist maintains that one must possess positive reasons in favor of other people's reliability or trustworthiness before their beliefs and testimony offer prima facie social evidence. The epistemic universalist, on the other hand, argues that the beliefs of all others are prima facie credible and should be treated accordingly. All this will set up subsequent discussion of the epistemic significance of common consent or widespread belief in God. I show how common consent arguments assume the epistemic universalist's account of the conditions under which the beliefs and testimony of others acquire reason-giving force as social evidence.

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.

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.

It is common to interpret Kant’s idea of public reason and the Enlightenment motto to ‘think for oneself’ as incompatible with the view that testimony and judgement of credibility is essential to rational public deliberation. Such interpretations have led to criticism of contemporary Kantian approaches to deliberative democracy for being intellectualistic, and for not considering our epistemic dependence on other people adequately. In this article, I argue that such criticism is insufficiently substantiated, and that Kant’s idea of public reason is (...) neither at odds with deference to a certain kind of authority, nor with making judgements of character in rational deliberation. This view is corroborated by recent work on Kant’s epistemology of testimony. (shrink)

The present paper argues for the relevance of Immanuel Kant and the German Enlightenment to contemporary social epistemology. Rather than distancing themselves from the alleged ‘individualism’ of Enlightenment philosophers, social epistemologists would be well-advised to look at the substantive discussion of social-epistemological questions in the works of Kant and other Enlightenment figures. After a brief rebuttal of the received view of the Enlightenment as an intrinsically individualist enterprise, this paper charts the historical trajectory of philosophical discussions of testimony as a (...) source of knowledge, via such philosophers as C. Thomasius, C. A. Crusius, J. M. Chladenius, G. F. Meier, and finally Kant. Building on recent work on Kant's epistemology of testimony, the paper considers Kant's broader contributions to social epistemology. This includes an analysis of Kant's comments on the social basis of contingent epistemic standards, e.g. in the sciences, as well as on problems arising from the management of what Kant calls the growing ‘volume of knowledge’. Special attention is paid to the relation between Kant's views and contemporary problems arising both in the context of education and from our increased reliance on scientific experts. (shrink)

Local reductionism purports to defend a middle ground in the debate about the epistemic status of testimony-based beliefs. It does so by acknowledging the practical ineliminability of testimony as a source of knowledge, while insisting that such an acknowledgment need not entail a default-acceptance view, according to which there exists an irreducible warrant for accepting testimony. The present paper argues that local reductionism is unsuccessful in its attempt to steer a middle path between reductionism and anti-reductionism about testimonial justification. In (...) particular, it challenges local reductionism 'from within', without appealing to anti-reductionist intuitions. By offering novel arguments to the effect that local reductionism fails by its own standards, the present paper considerably strengthens the case against this version of reductionism. Local reductionism, it is argued, fails for three main reasons. First, it cannot account for the rationality of testimonial rejection in paradigmatic cases, even though the possibility of rational rejection is thought to be of central justificatory importance. Second, it does not provide a sufficiently distinct non-testimonial basis to which testimonial justification can be successfully reduced. Finally, local reductionism is shown to be an intrinsically unstable position, in danger of collapsing into full-fledged 'credulism' of the kind historically associated with Thomas Reid. (shrink)

Let us focus on what I take it is the paradigm case of testimony—the intentional transfer of a belief from one agent to another, whether in the usual way via a verbal assertion made by the one agent to the other, or by some other means, such as through a note.1 So, for example, John says to Mary that the house is on fire (or, if you like, ‘texts’ her this message on her phone), and Mary, upon hearing this, forms (...) the belief that the house is on fire and consequently exits the building at speed. Clearly, a great deal of our beliefs are gained via testimony, and if the epistemic status of our testimonybased beliefs were to be called into question en masse, then this would present us with quite a predicament. It is thus essential that we have some plausible account of the epistemology of testimony. Our primary focus will be on the justification for our testimony-based beliefs, though along the way we will say a little about other relevant epistemic notions like epistemic entitlement as well.

Many epistemologists agree that even very young children sometimes acquire knowledge through testimony. In this paper I address two challenges facing this view. The first (building on a point made in Lackey (2005)) is the defeater challenge, which is to square the hypothesis that very young children acquire testimonial knowledge with the fact that children (whose cognitive immaturity prevents them from having or appreciating reasons) cannot be said to satisfy the No-Defeaters condition on knowledge. The second is the extension challenge, (...) which is to give a motivated, extensionally-adequate account of the conditions on testimonial knowledge in early childhood. Neither challenge can be met merely by endorsing externalism about knowledge; but we can meet both by reconceiving the process that eventuates in the child’s consumption of testimony. My central thesis is that this process should be seen as implicating features of the child's social environment. The result is a novel anti-individualistic externalism about knowledge. (shrink)

Among contemporary epistemologists of testimony, David Hume is standardly regarded as a ‘global reductionist’, where global reductionism requires the hearer to have sufficient first-hand knowledge of the facts in order to individually ascertain the reliability of the testimony in question. In the present paper, I argue that, by construing Hume’s reductionism in too individualistic a fashion, the received view of Hume on testimony is inaccurate at best, and misleading at worst. Overall, Hume is much more willing to regard testimonial acceptance (...) as a natural response to testimony than has traditionally been thought. In particular, Hume believes that indirect evidence of human nature and of the social world around us, can take the place of first-hand evidence of the track record of individual speakers or specific classes of testimony. In developing this interpretation of Hume’s views on testimony, the present paper draws on discussions found in the Treatise, the Enquiry, and in Hume’s writings on historical knowledge. In der zeitgenössischen Debatte um den erkenntnistheoretischen Status zeugnisbasiertenWissens wird gern auf David Hume als den Urheber eines „globalen Reduktionismus“ verwiesen, demzufolge der Zeugnisempfänger über ausreichend empirische Belege für die Verlässlichkeit des betreffenden Zeugnisses verfügen muss. Im vorliegenden Aufsatz soll gezeigt werden, dass die in der Literatur vorherrschende Meinung ein übertrieben „individualistisches“ Bild von Humes Reduktionismus zeichnet; dadurch wird Humes Position in der gegenwärtigen Debatte ungenau und bisweilen irreführend wiedergegeben. Bei genauerer Betrachtung erweist sich Hume als ausgesprochen aufgeschlossen gegenüber dem Akzeptieren fremden Zeugnisses und sieht darin eine Art Grundmuster im testimonialen Umgang mit anderen. Insbesondere konzediert Hume, dass indirekt erworbenes Wissen um die menschliche Natur und die soziale Welt an die Stelle direkter Belege für die Verlässlichkeit einzelner Zeugen treten kann. Die im vorliegenden Aufsatz entwickelte Neuinterpretation stützt sich auf den Treatise, den Enquiry und auf Humes Schriften zum Problem der historischen Erkenntnis. (shrink)

In his recent work in social epistemology, Alvin Goldman argues that truth is the fundamental epistemic end of education, and that critical thinking is of merely instrumental value with respect to that fundamental end. He also argues that there is a central place for testimony and trust in the classroom, and an educational danger in over‐emphasizing the fostering of students’ critical thinking. In this paper I take issue with these claims, and argue that (1) critical thinking is a fundamental end (...) of education, independently of its instrumental tie to truth, and (2) it is critical thinking, rather than testimony and trust, that is educationally basic. (shrink)

Testimonial knowledge sometimes depends on internalist epistemic conditions, those that thinkers are able to reflect upon. In the testimony literature the only internalist conditions that are considered are those concerning a hearer's knowledge of a speaker's reliability. I argue, however, that the relevant sense of internal"" should not be seen as referring to just the hearer's point of view, but rather to the points of view of both the hearer and the speaker. There are certain cases of testimonial knowledge transmission (...) that depend on the speaker's knowledge of his audience. These include cases of ""engineered knowledge"" in which a speaker deviously manipulates a hearer's beliefs. Such knowledge is therefore internalist because it depends on factors that are internal to the point of view of the speaker, and not merely on externalist factors such as the reliability of the speakers' and hearers' beliefs.".

It is frequently claimed that we can learn very little, if anything, about the aesthetic character of an artwork on the basis of testimony. Such disparaging assessments of the epistemic value of aesthetic testimony contrast markedly with our acceptance of testimony as an important source of knowledge in many other areas. There have, however, been a number of challenges to this orthodoxy of late; from those who seek to deny that such a contrast exists as well as attempts by those (...) who accept the distinction to provide an explanation and defence of the contrast. In Section I, I outline a little of the nature and history of the debate over aesthetic testimony. Section II, focuses on the opposing positions on aesthetic testimony, optimism and pessimism, and takes steps to clarify what exactly is at issue between them. In Section III, I survey considerations which have been adduced in favour of pessimism ranging from brute appeal to intuition to complex argumentation before turning in Section IV, to look at motivations for optimism. Finally, in Section V, I consider some alternative views which claim that, for a variety of reasons, it is a mistake to construe the debate over aesthetic testimony as concerned with the epistemic standing of aesthetic beliefs formed on the basis of testimony.

Most epistemologists of testimony assume that testifying requires that the beliefs to which speakers attest are identical to the beliefs that hearers accept. I argue that this characterization of testimony is misleading. Characterizing testimony in terms of duplicating speaker/hearer belief unduly resticts the variety of beliefs that might be accepted from speaker testimony.

In this paper I argue that RadicalInterpretation (RI), taken to be a methodological doctrine regarding the conditions under which an interpretation of an utterance is both warranted and correct, has unacceptable implications for the conditions on (ascriptions of) understanding. The notion of understanding at play is that which underwrites the testimonial transmission of knowledge. After developing this notion I argue that, on the assumption of RI, hearers will fail to have such understanding in situations in which we should want to (...) maintain otherwise. The overall effect of the argument is to provide a heretofore unexamined source of motivation for anti-individualistic approaches to the semantics of utterances. (shrink)

In his work on the epistemology of testimony, Peter Lipton developed an account of testimonial inference that aimed at descriptive adequacy as well as justificatory sophistication. According to ‘testimonial inference to the best explanation’, we accept what a speaker tells us because the truth of her claim figures in the best explanation of the fact that she made it. In this paper, I argue for a modification of this picture. In particular, I argue that IBE plays a dual role in (...) the management and justification of testimony. On the one hand, the coherence and success of our testimony-based projects provides general abductive support for a default stance of testimonial acceptance; on the other hand, we are justified in rejecting specific testimonial claims whenever the best explanation of the instances of testimony we encounter entails, or makes probable, the falsity or unreliability of the testimony in question.Keywords: Testimony; Inference to the best explanation; Abduction; Epistemic justification.

We citizens of the 21st century live in a world where division of epistemic labour rules. Most of what we know we learned from the spoken or written word of others, and we depend in endless practical ways on the technological fruits of the dispersed knowledge of others—of which we often know almost nothing—in virtually every moment of our lives. Interest has been growing in recent years amongst philosophers, in the issues in epistemology raised by this fact. One issue concerns (...) the depth and extent of our epistemic dependence on testimony, as we may label this broad epistemic source: Do we have any knowledge at all that is free of epistemic dependence on what we have learned from others? A related question is whether our entitlement to believe what we have learned from others can be explained without invoking any epistemic principles special to testimony. These questions concern, as it were, the macro-epistemology of testimony. In the present discussion I shall focus instead on the micro foundations. Testimony, in our broad sense, can occur through an extensive range of types of spoken and written means of purportedly factual communication, including telephone calls, e-mails and personal letters, lectures and radio broadcasts, newspapers, textbooks and encyclopaedias, personal diaries, and public records of all kinds. But the central paradigm—what started the whole communication thing off—is surely that of face-to-face spoken encounter, when one person tells something to another, thereby intending and hoping to share her knowledge with her audience. I begin by describing the speech act of telling, identifying what takes place in a felicitous act of telling. From the nature of the speech act of telling, we see precisely how it is that knowledge is, when all goes as it should, acquired from teller by trusting hearer, in such an act, and in acts of testimony more broadly.

Burge proposes the Acceptance Principle"", which states that it is apriori that a hearer may properly accept what she is told in the absence of defeaters, since any giver of testimony is a rational agent, and as such one can presume she is a ""source of truth"". It is claimed that Burge's Principle is not intuitively compelling, so that a suasive, not merely an explanatory justification for it is needed.

Recent work in epistemology has focused increasingly on the social dimensions of knowledge and inquiry. Education is one important social arena in which knowledge plays a leading role, and in which knowledge-claims are presented, analyzed, evaluated, and transmitted. Philosophers of education have long attended to the epistemological issues raised by the theory and practice of education . While historically philosophical issues concerning education were treated alongside other philosophical issues, in recent times the former set of issues have been largely neglected (...) by philosophers working in the core areas of the discipline. Interestingly, the rise of social epistemology has been accompanied by a renewed interest by mainstream philosophers in philosophical questions concerning education. Whether or not this accompaniment is accidental, or is legitimately explainable in terms of broad intellectual, philosophical, or social/political currents and movements, I will not endeavor to address here. The increasing respectability of and philosophical interest in both social epistemology and philosophy of education are in any case salutary developments, each signaling both a broadening of the set of interests and issues deemed legitimate by practitioners of the parent discipline, and an increased willingness to take seriously the philosophical problems raised by the ubiquitous social/communal effort to transmit/transform culture by way of education.

How is ethical knowledge possible? One of the most promising answers is the moral sense view: we can acquire ethical knowledge through emotional experience. But this view faces a serious problem. Emotions are unreliable guides to ethical truth, frequently failing to fit the ethical status of their objects. This threatens to render the habit of basing ethical beliefs on emotions too unreliable to yield knowledge. I offer a new solution to this problem, with practical implications for how we approach ethical (...) decision-making. I argue that an agent can have a reliable belief-forming habit despite having unreliable emotions, so long as she is suitably attentive to defeaters. In moderately virtuous agents, unfitting ethical emotions are frequently accompanied by warning signs, such as negative metaemotions, epistemic feelings, moods, and social cues. An agent who cultivates the attentional skill of noticing these signs can prevent many of her unfitting emotions from translating into false beliefs. For a moderately virtuous agent with this skill, the habit of basing ethical beliefs on emotions will be reliable. The upshot is that emotion-based ethical knowledge is possible even for people whose emotions are unreliable, but only if we cultivate the skill of spotting defeaters. (shrink)

A contemporary debate concerning the epistemology of testimony is portrayed by its protagonists as having its origins in the eighteenth century and the respective views of David Hume and Thomas Reid. Hume is characterized as a reductionist and Reid as an anti-reductionist. This terminology has been widely adopted and the reductive approach has become synonymous with Hume. In Sect. 1 I spell out the reductionist interpretation of Hume in which the justification possessed by testimonially-acquired beliefs is reducible to the epistemic (...) properties of perception, memory and inductive inference. This account of testimony is taken to be found in the section ‘On Miracles’ of Hume’s Enquiry concerning Human Understanding. In Sect. 2 I introduce the distinction between global and local reductionism, and Coady’s interpretation of Hume as a global reductionist. He takes Hume’s position to be untenable. The rest of the paper explores alternative interpretations of Hume. Section 3 develops a local reductionist interpretation of Hume on testimony. It is argued, though, that such an approach is unstable and, in response, Sect. 4 turns to anti-reductionism in its contemporary forms and in Reid’s teleological account. In Sect. 5 I argue for an anti-reductionist account of Hume, one drawn from his discussion of the testimony of history in the Treatise of Human Nature, thus moving away from the usually exclusive focus upon the discussion of miracles in the first Enquiry, upon which the reductionist interpretation is based. Given the standard meaning of ‘Humeanism’ in the current debate, my interpretation amounts to the claim that Hume is not a Humean with respect to testimony. (shrink)

Accounts of logical independence which coincide when applied in the case of classical logic diverge elsewhere, raising the question of what a satisfactory all-purpose account of logical independence might look like. ‘All-purpose’ here means: working satisfactorily as applied across different logics, taken as consequence relations. Principal candidate characterizations of independence relative to a consequence relation are that there the consequence relation concerned is determined by only by classes of valuations providing for all possible truth-value combinations for the formulas whose independence (...) is at issue, and that the consequence relation ‘says’ nothing special about how those formulas are related that it does not say about arbitrary formulas. Each of these proposals returns counterintuitive verdicts in certain cases—the truth-value inspired approach classifying certain cases one would like to describe as involving failures of independence as being cases of independence, and the de Jongh approach counting some intuitively independent pairs of formulas as not being independent after all. In final section, a modification of the latter approach is tentatively sketched to correct for these misclassifications. The attention is on conceptual clarification throughout, rather than the provision of technical results. Proofs, as well as further elaborations, are lodged in the ‘longer notes’ in a final Appendix.

Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

We sketch and defend a Commitment View of testimony. Unlike alternative approaches, we focus on the ordinary act of testifying, attempting to identify the commitments essential to this speech act and to explain why those commitments are practically necessary. In view of this account, we argue that given the commitments undertaken in testifying, a speaker’s testimony can qualify as evidence.

Several current debates in the epistemology of testimony are implicitly motivated by concerns about the reliability of rules for changing one’s beliefs in light of others’ claims. Call such rules testimonial norms (tns). To date, epistemologists have neither (i) characterized those features of communities that influence the reliability of tns, nor (ii) evaluated the reliability of tns as those features vary. These are the aims of this paper. I focus on scientific communities, where the transmission of highly specialized information is (...) both ubiquitous and critically important. Employing a formal model of scientific inquiry, I argue that miscommunication and the “communicative structure” of science strongly influence the reliability of tns, where reliability is made precise in three ways.

As a belief source, testimony has long been held by theorists of the mind to play a deeply important role in human cognition. It is unclear, however, just why testimony has been afforded such cognitive importance. We distinguish three suggestions on the matter: the number claim, which takes testimony’s cognitive importance to be a function of the number of beliefs it typically yields, relative to other belief sources; the reliability claim, which ties the importance of testimony to its relative truth-conduciveness; (...) and the scope claim, according to which testimony’s importance is a function of its relative representational power, non-numerically conceived. After laying out these three suggestions, we go on to argue that there is little hope of grounding testimony’s cognitive importance in either the number claim or the reliability claim. We conclude with a tentative exploration of the basis and plausibility of the scope claim. (shrink)

Since the last two decades of the 20th century it has been widely accepted that testimony has to be acknowledged as a source of knowledge. As a side effect, any form of epistemic individualism has been discredited. The article provides some arguments against the dismissive attitude towards epistemic individualism. I distinguish between three forms of epistemic individualism, and I argue that only the most extreme form can be flatly rejected while there are good reasons for maintaining the other two forms (...) of epistemic individualism. I show that weak individualism, according to which individuals are the bearers of knowledge, is concerned with a necessary condition of the instantiation of knowledge. We only accept knowledge claims if there is good reason to believe that they are maintained by at least one individual. My main interest, however, is focused on a discussion of the third more challenging form of epistemic individualism, namely normative epistemic individualism, which claims that priority of one’s own epistemic experiences over the testimony of others. I first swow that such a priority claim can only be understood as a local device, i.e. if a belief based on our own experiences is challenged by other people’s assertations, then we are committed to trust our own experiences more than the words of others. In a second step, the relations between such a restricted version of the individualist priority claim and the ideal of rationality are discussed. (shrink)

This paper attempts two things: to give the reader a very general idea of the main outlines of what Govier has to say both about social and political trust and about trust in personal relationships, and to present in slightly more detail what she says about the role of trust in acquiring belief and/or knowledge from testimony and about the reasons for trusting such testimony.
