In “Group Testimony” (2007) I argued that the testimony of a group cannot be understood (or at least cannot always be understood) in a summative fashion; as the testimony of some or all of the group members. In some cases, it is the group itself that testifies. I also argued that one could extend standard reductionist accounts of the justification of testimonial belief to the case of testimonial belief formed on the basis of group testimony. In this paper, I explore (...) the issue of group testimony in greater detail by focusing on one putative source of testimony, that of Wikipedia. My aim is to the answer the following questions: Is Wikipedia a source of testimony? And if so, what is the nature of that source? Are we to understand Wikipedia entries as a collection of testimonial statements made by individuals, some subset of individuals, or is Wikipedia itself (the organization or the Wikipedia community) the entity that testifies? If Wikipedia itself is a source of testimony, what resources do we have for assessing the trustworthiness of such an unusual epistemic source? In answering these questions I hope to further elucidate the nature of collective epistemic agency (Tollefsen 2006), of which group testimony is a paradigm example. When a mans Discourse begineth…at some saying of another, of whose ability to know the truth, and of whose honesty in not deceiving, he doubteth not; and then the Discourse is not so much concerning the Thing, as the Person; and the Resolution is called Beleefe, and Faith: Faith in the man. (1651/1991, Ch. 7; p. 48). (shrink)

The fact that much of our knowledge is gained through the testimony of others challenges a certain form of epistemic individualism. We are clearly not autonomous knowers. But the discussion surrounding testimony has maintained a commitment to what I have elsewhere called epistemic agent individualism. Both the reductionist and the anti-reductionist have focused their attention on the testimony of individuals. But groups, too, are sources of testimony - or so I shall argue. If groups can be testifiers, a natural question (...) to ask is whether our beliefs based on the testimony of groups are ever justified and whether such a justification is to be conferred inferentially or non-inferentially. I consider and dismiss the possibility of extending an anti-reductionist account of justification to our group testimonial beliefs. I also argue against a version of reductionism that would have our group testimonial beliefs justified only in so far as we were able to monitor the trustworthiness of members of the group. However, there are forms of reductionism that can be extended to make sense of the justification of our group testimonial beliefs. There are mechanisms for monitoring the trustworthiness and competency of a group (rather than its members) and, further, a variety of background beliefs allow us to assess the testimony of a group for reliability.

The guiding idea of Patricia Kitcher's Freud's Dream is that the use of interdisciplinary methodology accounts at the same time for the most central features of Freud's theory of the mind and for its most serious shortcomings. Kitcher proposes to provide an account of Freud's theory that illuminates its interdisciplinary underpinnings. While she indisputably succeeds in providing a subtle and rich reconstruction of Freud's work, her attempt to show up the limitations of interdisciplinary studies does not work. The value of (...) her account is attributable not to the idea that Freud's was a flawed interdisciplinary endeavour but to a contextually and historically sensitive approach that makes explicit and elucidates the norms of explanation at work in his method of theory construction and that takes into account the multifaceted nature of his scientific practice.

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)

Most explanations of the rational authority of testimony provide little guidance when evaluating individual pieces of testimony. In practice, however, we are remarkably sensitive to the varying epistemic credentials of testimony: extending trust when it is deserved, and withholding it when it is not. A complete account of the epistemology of testimony should, then, have something to say about when it is that testimony is trustworthy. In the typical case, to judge someone trustworthy requires judging them to be competent and (...) sincere. In this essay we develop an exchange-based account of testimony that shows how those who receive testimony are in a position to evaluate the sincerity of speakers. (shrink)

In this paper, I offer a contribution to the debate on testimony that rests on three elements: the definition of semantic information, the analysis of trust as a second?order property of first?order relations, and Floridi?s Network Theory of Account (NTA). I argue that testimony transmits semantic information and it is neither grounded on trust nor justified by it. Instead, I show that testimony is an occurrence of a first?order relation of communication affected by the second?order property of trust. I then (...) defend the view that an epistemic agent can acquire some knowledge, on the basis of the information communicated through testimony, if and only if the agent is able to connect the transmitted information to the conceptual network of interrelation to which it belongs. I refer to Floridi?s NTA to show how such a network allows the epistemic agent to achieve knowledge on the basis of semantic information. (shrink)

Social epistemologists should be well-equipped to explain and evaluate the growing vulnerabilities associated with filter bubbles, echo chambers, and group polarization in social media. However, almost all social epistemology has been built for social contexts that involve merely a speaker-hearer dyad. Filter bubbles, echo chambers, and group polarization all presuppose much larger and more complex network structures. In this paper, we lay the groundwork for a properly social epistemology that gives the role and structure of networks their due. In particular, (...) we formally define epistemic constructs that quantify the structural epistemic position of each node within an interconnected network. We argue for the epistemic value of a structure that we call the (m,k)-observer. We then present empirical evidence that (m,k)-observers are rare in social media discussions of controversial topics, which suggests that people suffer from serious problems of epistemic vulnerability. We conclude by arguing that social epistemologists and computer scientists should work together to develop minimal interventions that improve the structure of epistemic networks. (shrink)

We contest each other's memory claims all the time. I am concerned with how the contesting of memory claims and narratives may be an integral part of many abusive situations. I use the writings of Otto Weininger and the False Memory Syndrome Foundation to explore a particular strategy of discrediting women as rememberers, making them more vulnerable to sexual harm. This strategy relies on the presentation of women as unable to maintain a stable enough sense of self or identity to (...) be trustworthy testifiers to their own harm. (shrink)

The basic alternatives seem to be either a Humean reductionist view that any particular assertion needs backing with inductive evidence for its reliability before it can retionally be believed, or a Reidian criterial view that testimony is intrinscially, though defeasibly, credible, in the absence of evidence against its reliability.Some recent arguments from the constraints on interpreting any linguistic performances as assertions with propositional content have some force against the reductionist view. We thus have reason to accept the criterial view, at (...) least as applied to eyewitness reports. But these considerations do not establish that any rational enquirer must have the concept of other minds or testimony. The logical possibility of the lone enquirer, who uses symbols and thereby expresses some knowledge of his world, remains open — but it is a question we have no need to pronounce upon. (shrink)

What is the point of developing an epistemology for a topic—for example, morality? When is it appropriate to develop the epistemology of a topic? For many topics—for example, the topic of socks—we see no need to develop a special epistemology. Under what conditions, then, does a topic deserve its own epistemology? I seek to answer these questions in this article. I provide a criterion for deciding when we are warranted in developing an epistemological theory for a topic. I briefly apply (...) this criterion to moral epistemology and argue that some approaches to moral epistemology should be abandoned. I also argue that we can develop an epistemology for a topic without committing ourselves to a specific substantive theory of justification, such as reliabilism or coherentism, if we work within a suitably neutral framework.

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.

This article intends to show that the defense of “understanding” as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one (...) hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students’ belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

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.

This paper addresses the meta-epistemological dispute over the basis of epistemic evaluation from the standpoint of meliorative epistemology. Meliorative epistemology aims at guiding our epistemic practice to better results, and it comprises two levels of epistemic evaluation. At the social level (meliorative social epistemology) appropriate experts conduct evaluation for the community, so that epistemic evaluation is externalist since each epistemic subject in the community need not have access to the basis of the experts' evaluation. While at the personal level (meliorative (...) personal epistemology) epistemic evaluation is internalist since each member of the community must evaluate the reliability of the (apparent) experts from the first-person perspective. I argue that evaluation at the social level should be the primary focus of meliorative epistemology since meliorative personal epistemology does not provide informative epistemic norms. It is then pointed out that epistemic evaluation at the social level can be considered internalist in the extended sense (social internalism) in that every component of the evaluation needs to be recognized by some members of the community at some points. As a result, some familiar problems of internalist epistemology, such as regress and circularity of epistemic support, carry over to meliorative social epistemology. (shrink)

This paper defends reductionism about testimonial justification of beliefs against two influential arguments. One is the empirical argument to the effect that the reductionist justification of our trust in testimony is either circular since it relies on testimonial evidence or else there is scarce evidence in support of our trust in testimony. The other is the transcendental argument to the effect that trust in testimony is a prerequisite for the very existence of testimonial evidence since without the presumption of people’s (...) truthfulness we cannot interpret their utterances as testimony with propositional contents. This paper contends that the epistemic subject can interpret utterances as testimony with propositional contents without presupposing the credibility of testimony, and that evidence available to the normal epistemic subject can justify her trust in testimony.

In this essay, I attempt to outline a feminist philosophical approach to the current debate concerning (allegedly) false memories of childhood sexual abuse. Bringing the voices of feminist philosophers to bear on this issue highlights the implicit and sometimes questionable epistemological, metaphysical, and ethical-political commitments of some therapists and scientists involved in these debates. It also illuminates some current debates in and about feminist philosophy.

The study of human diversity in the first half of the 19th century has traditionally been categorized as a type of armchair-based natural history. If we are to take seriously this characterization of the discipline it requires further unpacking. Armchair anthropology was not a passive pursuit, with minimal analytical reflection that simply synthesized the materials of other writers. Nor was it detached from the activities of informants who were collecting and recording data in the field. Practitioners in the 19th century (...) were highly attuned to the problems associated with their research techniques and continually sought to transform their methodologies. The history of British anthropological research is one of gradual change and the adoption of new observational techniques into its methodologies. This article looks at the history of 19th-century British anthropology and examines in detail the observational practices of its researchers. In doing so it aims to answer the question: What is armchair anthropology? (shrink)

Zeugenschaft ist heute wichtiger denn je – und das nicht trotz, sondern vielmehr gerade wegen der gewachsenen Möglichkeiten, jederzeit und überall das Geschehen technisch aufzunehmen und einer breiten Öffentlichkeit zugänglich zu machen. Zeugenschaft ist jedoch nicht nur eine epistemische Praxis, sondern auch eine Form sozialen Engagements, wie die sozialen Protestbewegungen der letzten Jahre gezeigt haben. In den aktuellen Debatten um Zeugenschaft ist allerdings eine gewisse Verengung hin auf die epistemischen Aspekte des Zeugnisgebens zu beobachten. Dagegen versucht der Artikel, Praktiken der (...) Zeugenschaft auf ihre ethischen und politischen Implikationen hin zu befragen. Dabei gilt es, kritisch auf die Normen zu reflektieren, die Zeugenschaft ermöglichen oder verhindern. Zugleich impliziert jedes Zeugnis ein politisches Moment, insofern sich das Wahrsprechen des Zeugen bzw. der Zeugin selbst als politischer Akt interpretieren lässt. Zeugnisgeben erweist sich damit, so die These, nicht nur als eine epistemische, sondern auch als eine ethische und politische Praxis, ohne dass diese Elemente aufeinander reduzierbar wären. (shrink)

Indicators of the reliability of informants are essential for social learning in a society that is initially dominated by ignorance or superstition. Such reliability indicators should be based on meta-induction over records of truth-success. This is the major claim of this paper, and it is supported in two steps. One needs a non-circular justification of the method of meta-induction, as compared to other learning methods. An approach to this problem has been developed in earlier papers and is reported in section (...) 2. It is based on the predictive optimality of meta-inductive learning, under the assumption that objective success records are globally available. The rest of the paper develops an extension of this approach, so-called local meta-induction. Here individuals can access only success records of individuals in their immediate epistemic neighborhood. It is shown that local meta-inductive learning can spread reliable information over the entire population, and has clear advantages compared to success-independent social learning methods such as peer-imitation and authority-imitation.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

Many contemporary social epistemologists take themselves to be combatting an individualist approach to knowledge typified by Descartes. Although I agree that Descartes presents an individualist picture of scientific knowledge, he does allow some practical roles for reliance on the testimony and beliefs of others. More importantly, however, his reasons for committing to individualism raise important issues for social epistemology, particularly about how reliance on mere testimony can propagate prejudices and inhibit genuine understanding. The implications of his views are worked out (...) more fully by some of his immediate successors; I examine how François Poulain de la Barre, and (briefly) Mary Astell analyze the social conditions for epistemic agency in a Cartesian vein. (shrink)

One of the central points of contention in the epistemology of testimony concerns the uniqueness (or not) of the justification of beliefs formed through testimony--whether such justification can be accounted for in terms of, or 'reduced to,' other familiar sort of justification, e.g. without relying on any epistemic principles unique to testimony. One influential argument for the reductionist position, found in the work of Elizabeth Fricker, argues by appeal to the need for the hearer to monitor the testimony for credibility. (...) Fricker (1994) argues, first, that some monitoring for trustworthiness is required if the hearer is to avoid being gullible, and second, that reductionism but not anti-reductionism is compatible with ascribing an important role to the process of monitoring in the course of justifiably accepting observed testimony. In this paper we argue that such an argument fails. (shrink)

Testimony is an indispensable source of information. Yet, contrary to ‘literalism’, speakers rarely mean just what they say; and even when they do, that itself is something the hearer needs to realize. So, understanding instances of testimony requires more than merely reading others' messages off of the words they utter. Further, a very familiar and theoretically well-entrenched approach to how we arrive at such understanding serves to emphasize, not merely how deeply committed we are to testimony as a reliable source (...) of information, but that epistemological questions about testimonial belief are – perhaps even must be – posterior to such a commitment. This result does not itself dictate any particular views on the epistemology of testimony. However, not only does the failure of literalism not support the view that the justificatory basis of testimony-based beliefs is importantly inferential; it in fact undermines a key premise in one important argument for the view that one needs independent, positive reasons for accepting a given testimonial report. More generally, the present paper illustrates how discussions of the epistemology of testimony might usefully interact with an examination of the epistemology of understanding. (shrink)

In recent years, feminist philosophy of science has been subjected to criticism. The debate has focused on the implications of the underdetermination thesis for accounts of the role of social values in scientific reasoning. My aim here is to offer a different approach. I suggest that feminist philosophers of science contribute to our understanding of science by (1) producing gender‐sensitive analyses of the social dimensions of scientific inquiry and (2) examining the relevance of these analyses for normative issues in philosophy (...) of science.

: It is now recognized that relations of trust play an epistemic role in science. The contested issue is under what conditions trust in scientific testimony is warranted. I argue that John Hardwig's view of trustworthy scientific testimony is inadequate because it does not take into account the possibility that credibility does not reliably reflect trustworthiness, and because it does not appreciate the role communities have in guaranteeing the trustworthiness of scientific testimony.

This article briefly considers current positions about whether the inclusion of the perspectives and interests of marginalised groups in the construction of knowledge is of epistemic value. It is then argued that applied social epistemology is the proper epistemic stance to take in evaluating this question. Theorists who have held that diversity makes an epistemic contribution are interpreted as attempting to reform social pathways to knowledge in ways that make true belief more likely. Thus, the demand for diversity challenges the (...) individualistic and a priori nature of traditional epistemology. This stance has consequences for education. It supports greater attention to helping students examine the testimonial bases for their beliefs. And it prepares students for their role as citizens in supporting policies that maintain credible inclusive institutions of public knowledge. (shrink)

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.

How do we form aesthetic judgements? And how should we do so? According to a very prominent tradition in aesthetics it would be wrong to form our aesthetic judgements about a particular object on the basis of anything other than first-hand acquaintance with the object itself (or some very close surrogate) and, in particular, it would be wrong to form such judgements merely on the basis of testimony. Further this tradition presupposes that our actual practice of forming aesthetic judgements typically (...) meets, or at least approximates, this ideal. In this paper I target this descriptive claim and argue—by appeal to some empirical work concerning belief polarization and echo chambers in aesthetics—that our actual practice of forming aesthetic judgements is heavily dependent on social sources such as testimony. I then briefly consider what normative implications this descriptive claim may have. (shrink)

Deepfakes are a new form of synthetic media that broke upon the world in 2017. Bringing photoshopping to video, deepfakes replace people in existing videos with someone else’s likeness. Currently most of their reach is limited to pornography, and they are also used to discredit people. However, deepfake technology has many epistemic promises and perils, which concern how we fare as knowers. Our goal is to help set an agenda around these matters, to make sure this technology can help realize (...) epistemic rights and epistemic justice and unleash human creativity, rather than inflict epistemic wrongs of any sort. Our project is exploratory in nature, and we do not aim to offer conclusive answers at this early stage. There is a need to remain vigilant to make sure the downsides do not outweigh the upsides, and that will be a tall order. (shrink)

Scientificity is essentially methodology. The use of information technology as methodological instruments in science has been increasing for decades, this raises the question: Does this transform science? This question is the subject of the Special Issue in Minds and Machines “The epistemological significance of methods in computer simulation and machine learning”. We show that there is a technological change in this area that has three methodological and epistemic consequences: methodological opacity, reproducibility issues, and altered forms of justification.

What is the nature of deep disagreement? In this paper, I consider two similar albeit seemingly rival answers to this question: the Wittgensteinian theory, according to which deep disagreements are disagreements over hinge propositions, and the fundamental epistemic principle theory, according to which deep disagreements are disagreements over fundamental epistemic principles. I assess these theories against a set of desiderata for a satisfactory theory of deep disagreement, and argue that while the fundamental epistemic principle theory does better than the Wittgensteinian (...) theory on this score, the fundamental epistemic principle theory nevertheless struggles to explain the variety of deep disagreement.

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.

The objective of this paper is to apply the general idea of contextualism, as a theory of knowledge attribution, to the very specific case of testimony and trust characterized as being the procedure of the attribution of knowledge (and sincerity) to the informant. In the first part, I argue in favor of evidentialism, a viewpoint that takes epistemically responsible trust as a matter of evidence. In the second part, I consider the question of how strong an evidential basis has to (...) be for epistemically responsible trust. I have briefly registered two main tendencies in contemporary debates regarding trust and testimony: (i) the non-unitary character of our trust; (ii) and the requirement for a refinement of evidential standards. In short, I argue in favor of the stance that any ‘undiscriminatory generalization’ (both Redian or anti-reductivist and Humean or reductivist) concerning epistemically responsible trust is a kind of inappropriate theoretical idealization, and that a certain theoretical reconciliation has to be offered. Finally, in the third part, I propose trust-contextualism as the viewpoint that optimally harmonizes both our intuitive and theoretical requirements about epistemically responsible trust. (shrink)

How much linguistic understanding is required for testimonial knowledge acquisition? One answer is that, so long as we grasp the content expressed by the speaker, it does not matter if our understanding of it is poor. Call this the ‘Liberal View’ of testimony. This approach looks especially promising when combined with the thesis that we share a public language that makes it easy to grasp the right content. In this paper, I argue that this picture is epistemically problematic. Poor linguistic (...) understanding undermines our ability to recognise evidence and counterevidence for the testimonial content. Because of this, in many cases in which a hearer’s understanding is poor, her resultant testimonial belief will lack sufficient warrant to qualify as knowledge. Given that we often do not possess a sufficiently good understanding of the testimony we consume, I argue that we acquire far less knowledge through testimony than the Liberal View suggests.

Abstract At stake in the dispute between Campbell and Hume is the basis for our acceptance of testimony. Campbell argues that, contrary to Hume, our acceptance of testimony is prior to experience, while Hume continues to maintain that the appropriation through testimony of the experience of others depends ultimately on one's own experience. I argue that Hume's remarks about testimony provide a non-circular account of the process by which the experience of others may become one's own; and I suggest that (...) the view of Campbell and Hume as proponents of two radically opposed positions on the epistemology of testimony represents a considerable over-simplification.

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.

Durante los últimos años, el problema de cómo justificar aquellas creencias que se originan en testimonios ha ocupado un lugar central en la epistemología. Sin embargo, muy pocas de esas reflexiones son conocidas en el derecho probatorio. En el presente ensayo analizo la prueba testimonial a la luz de estas reflexiones con el fin de poner de manifiesto los supuestos epistemológicos de algunos principios procesales. En concreto, analizo la legislación colombiana y la estadounidense en el marco de la disputa entre (...) el reduccionismo y el antirreduccionismo en la filosofía del testimonio. Al final sugiero una nueva aproximación epistemológica que replantea los términos de la disputa y que tiene implicaciones importantes para la valoración de la prueba testimonial en los procesos judiciales.

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.

Although there is widespread agreement that our epistemic dependence on other people's knowledge is a key ingredient of our cognitive life, the role of trust in this dependence is much more open to debate. Is trust in epistemic authority—or “epistemic trust” for short—an epistemological notion in any sense, or is it simply a bridge-concept that connects our epistemological concerns to moral issues? Should we depict it in terms of the more familiar sociological notion of trust as a basis for cooperation?

There is an emerging consensus in the literature on probabilistic coherence that such coherence cannot be truth conducive unless the information sources providing the cohering information are individually credible and collectively independent. Furthermore, coherence can at best be truth conducive in a ceteris paribus sense. Bovens and Hartmann have argued that there cannot be any measure of coherence that is truth conducive even in this very weak sense. In this paper, I give an alternative impossibility proof. I provide a relatively (...) detailed comparison of the two results, which turn out to be logically unrelated, and argue that my result answers a question raised by Bovens and Hartmann’s study. Finally, I discuss the epistemological ramifications of these findings and try to make plausible that a shift to an explanatory framework such as Thagard’s is unlikely to turn the impossibility into a possibility.

Contrary to current individualistic epistemology, Classical rhetoric provides us with a pragmatical and particularly dynamic conception of ‘testimony’ as a source made available for the orator by the particular community in which she acts. In order to count as usable testimony, a testimony to which one could appeal in further communications, any discourse must comply with specific rules of social sanction. A deliberate attention to the social practices in which testimony is given and assessed may offer us a more accurate (...) view of its epistemological role. (shrink)

Search engines are important contemporary sources of information and contribute to shaping our beliefs about the world. Each time they are consulted, various algorithms filter and order content to show us relevant results for the inputted search query. Because these search engines are frequently and widely consulted, it is necessary to have a clear understanding of the distinctively epistemic role that these algorithms play in the background of our online experiences. To aid in such understanding, this paper argues that search (...) engine algorithms are providers of “bent testimony”—that, within certain contexts of interactions, users act as if these algorithms provide us with testimony—and acquire or alter beliefs on that basis. Specifically, we treat search engine algorithms as if they were asserting as true the content ordered at the top of a search results page—which has interesting parallels with how we might treat an ordinary testifier. As such, existing discussions in the philosophy of testimony can help us better understand and, in turn, improve our interactions with search engines. By explicating the mechanisms by which we come to accept this “bent testimony,” our paper discusses methods to help us control our epistemic reliance on search engine algorithms and clarifies the normative expectations one ought to place on the search engines that deploy these algorithms.
