Testimony about the future dangerousness of a person has become a central staple of many judicial processes. In settings such as bail, sentencing, and parole decisions, in rulings about the civil confinement of the mentally ill, and in custody decisions in a context of domestic violence, the assessment of a person’s propensity towards physical or sexual violence is regarded as a deciding factor. These assessments can be based on two forms of expert testimony: actuarial or clinical. The (...) purpose of this paper is to examine the scientific and epistemological basis of both methods of prediction or risk assessment. My analysis will reveal that this kind of expert testimony is scientifically baseless. The problems I will discuss will generate a dilemma for factfinders: on the one hand, given the weak predictive abilities of the branches of science involved, they should not admit expert clinical or actuarial testimony as evidence; on the other hand, there is a very strong tradition and a vast jurisprudence that supports the continued use of this kind of expert testimony. It is a clear case of the not so uncommon conflict between science and legal tradition. (shrink)

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)

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)

Recent work in artificial intelligence has increasingly turned to argumentation as a rich, interdisciplinary area of research that can provide new methods related to evidence and reasoning in the area of law. Douglas Walton provides an introduction to basic concepts, tools and methods in argumentation theory and artificial intelligence as applied to the analysis and evaluation of witness testimony. He shows how witness testimony is by its nature inherently fallible and sometimes subject to disastrous failures. At the same (...) time such testimony can provide evidence that is not only necessary but inherently reasonable for logically guiding legal experts to accept or reject a claim. Walton shows how to overcome the traditional disdain for witness testimony as a type of evidence shown by logical positivists, and the views of trial sceptics who doubt that trial rules deal with witness testimony in a way that yields a rational decision-making process.

We describe a software system for the analysis of defined benefit actuarial plans. The system uses a recursive formulation of the actuarial stochastic processes to implement precise and efficient computations of individual and group cash flows.

Our trust in the word of others is often dismissed as unworthy, because the illusory ideal of "autonomous knowledge" has prevailed in the debate about the nature of knowledge. Yet we are profoundly dependent on others for a vast amount of what any of us claim to know. Coady explores the nature of testimony in order to show how it might be justified as a source of knowledge, and uses the insights that he has developed to challenge certain widespread (...) assumptions in the areas of history, law, mathematics, and psychology.

In actuarial parlance, the price of an insurance policy is considered fair if customers bearing the same risk are charged the same price. The estimate of this fair amount hinges on the expected value obtained by weighting the different claims by their probability. We argue that, historically, this concept of actuarial fairness originates in an Aristotelian principle of justice in exchange (equality in risk). We will examine how this principle was formalized in the 16th century and shaped in (...) life insurance during the following two hundred years, in two different interpretations. The Domatian account of actuarial fairness relied on subjective uncertainty: An agreement on risk was fair if both parties were equally ignorant about the chances of an uncertain event. The objectivist version grounded any agreement on an objective risk estimate drawn from a mortality table. We will show how the objectivist approach collapsed in the market for life annuities during the 18th century, leaving open the question of why we still speak of actuarial fairness as if it were an objective expected value.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Testimony of Sense: Empiricism and the Essay from Hume to Hazlitt by Tim MilnesMargaret WatkinsTim Milnes. The Testimony of Sense: Empiricism and the Essay from Hume to Hazlitt. Oxford: Oxford University Press, 2019. Pp. viii + 278. Hardback. ISBN: 9780198812739. $91.00.In his brief autobiography, “My Own Life,” Hume reports that “almost all [his] life has been spent in literary pursuits and occupations” (E-MOL: xxxi). This (...) is one of at least ten places in this brief work in which he associates himself with “letters” or “literature”—as compared to at most four associations with philosophy. The moral to be inferred is not that Hume considered himself not to be a philosopher. Rather, he conceived of philosophy as a kind of literature. The Treatise was itself a “literary attempt.” Indeed, opposition between the “literary” and “philosophical” aspects of a text would have been foreign to Hume and his contemporaries—a notion for a later age, despite his occasional loose distinction between the relevant genres, as in his list of writings “historical, philosophical, or literary” in “My Own Life” (E-MOL: xxxvi).Yet despite Hume’s own understanding of the continuity between philosophy and literature, broadly conceived, it is still common for contemporary philosophers to ignore literary questions in their examination of Hume’s work, or to presume that one can easily distinguish the “philosophical” parts from the “literary” ones. Tim Milnes’s The Testimony of Sense is therefore a welcome addition to the Hume literature (pun intended). With a particular focus on the essay—a genre of great importance to Hume—Milnes contributes to the small set of engagements with Hume from the disciplinary perspective of English literature. With training in both philosophy and literature, as well as established expertise on Romanticism and its own essays, Milnes is well-qualified for the task. The Testimony of Sense includes sustained engagement with Hume’s contemporaries and successors, but for the purposes of this review, I engage the book primarily as a Hume scholar for Hume scholars.Milnes’s story plays out in three acts. The first establishes the need for public trust created by a skeptical crisis, itself a product of Hume’s criticism of the epistemic program of thinkers in the Cartesian and Lockean traditions. The second explains how the essays of the long eighteenth century constitute a response to that need in various ways. The third reveals in detail how the Romantic essayists, particularly William Hazlitt and Charles Lamb, both respond to and deviate from the “neoclassical” essayists, typified by Hume and Samuel Johnson.The first chapter, “Self and Intersubjectivity,” lays the groundwork by articulating how Hume, Adam Smith, Thomas Reid, and Dugald Stewart identify the need for what we now call intersubjectivity. Milnes describes the common thread as a kind of “natural transcendentalism.” In what sense are these thinkers properly understood as [End Page 175] transcendentalists? The central idea seems to be that all posit things other than reason as “conditions of meaningful thought” (72). For Hume, it is the social, linguistic experience of a community of virtuous judges. The intricate relations between self and other essential to such a community get “internalized within the specular drama of the impartial spectator” (72) in Smith’s writing, which itself takes part in the drama through his “halting, qualified syntax” that mimics “everyday speech” (44). Reid posits a “prescience” of trust, which grounds our reliance on both human testimony and the uniformity of nature, itself undergirded by the design of a benevolent God. Stewart, who posits axiomatic truths that help constitute the “stamina of intellect,” goes furthest, actually calling these truths transcendental (55). This chapter also puts these eighteenth-century thinkers in conversation with twentieth-century theorists, including Habermas, Davidson, and Rorty.Chapter 2, “The Subject of Trust,” deepens the analysis by situating these “natural transcendentalisms” in the broader enlightenment context. In contrast to Descartes, Bacon, and Locke, who were suspicious of our reliance on the opinions of others, the eighteenth-century thinkers understand trust as prior to reason in various ways—though not prior to solidarity. The particulars in each case depend on their responses to skepticism and their accounts of the relation between... (shrink)

In Testimony, Trust, and Authority, Benjamin McMyler argues that philosophers have failed to appreciate the nature and significance of our epistemic dependence ...

Why is there a felt asymmetry between cases in which agents defer to testifiers for certain moral beliefs, and cases in which agents defer on many other matters? One explanation influential in the literature is that having understanding of a proposition is both in tension with acquiring belief in the proposition by deferring to another's testimony and distinctively important when it comes to moral propositions, as compared with what we might think of as many ‘garden variety’ facts. My project (...) in this paper is to offer a new and more defensible version of this explanation. This will involve re-conceiving understanding as a richer state than it is commonly thought to be, requiring affective and motivational engagement with reasons as well as cognitive facility. I also offer a new explanation of the tension between understanding and deference to testimony. (shrink)

Scientific Testimony concerns the roles of scientific testimony in science and society. The book develops a positive alternative to a tradition famously expressed by the slogan of the Royal Society Nullius in verba ("Take nobody's word for it"). This book argues that intra-scientific testimony—i.e., testimony between collaborating scientists—is not in conflict with the spirit of science or an add-on to scientific practice. On the contrary, intra-scientific testimony is a vital part of science. This is illustrated (...) by articulating epistemic norms of intra-scientific testimony and arguing that they are vital to scientific methodology on a par with other scientific norms governing scientific observation and data analysis. -/- The book also provides an account of public scientific testimony—i.e., scientific testimony to the lay population. This is done by integrating philosophical resources with empirical research on the science of science communication. For example, various misconceptions about science and folk epistemological biases are diagnosed as factors that contribute to science skepticism. This diagnosis provides the basis for developing novel norms for science communication that are sensitive to the psychological and social obstacles to laypersons' uptake of it. Finally, the volume discusses how public scientific testimony is best embedded in society and argues that it is critical for societies that pursue the ideals of deliberative democracy. Scientific Testimony draws on philosophy of science, social epistemology, and empirical research to provide a wide-ranging account of the roles of scientific testimony within scientific practice and within the wider society.

I examine a distinctive kind of injustice which arises when people are maltreated in their capacity as potential conveyors of knowledge. Extant discussions of testimonial injustice usually assume that the injustice occurs when an audience ignores the claims made by a testifier. This assumption obscures the fact that there are occasions where the best framework for thinking about testimonial injustice is that of inappropriately rejecting, not ignoring, those claims; the injustice differs in these two kinds of case. Light is thrown (...) on the injustice involved in inappropriate rejection by examining the epistemic import of the distinctive second-person interrelations in play in such testimonial interactions.

Through a detailed analysis that draws on work across philosophy, the law, and social psychology, this book shows that, from the very beginning of the American criminal legal process in interrogation rooms to its final stages in front of parole boards, testimony is extracted from individuals through processes that are coercive, manipulative, or deceptive. This testimony is then unreasonably regarded as representing the testifiers’ truest or most reliable selves. With chapters ranging from false confessions and eyewitness misidentifications to (...) recantations from victims of sexual violence and expressions of remorse from innocent defendants at sentencing hearings, it is argued that there is a distinctive epistemic wrong being perpetrated against suspects, defendants, witnesses, and victims. This wrong involves brute State power targeting the epistemic agency of its citizens, extracting false testimony that is often life-shattering, and rendering the victims in question complicit in their own undoing. It is concluded that it is only through understanding what it means to respect the epistemic agency of each participant in the criminal legal system that we can truly grasp what justice demands and, in so doing, to reimagine what is possible.

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)

Insurance is pervasive in many social settings. As a cooperative device based on risk pooling, it serves to attenuate the adverse consequences of various risks by offering policyholders coverage against the losses implied by adverse events in exchange for the payment of premiums. In the insurance industry, the concept of actuarial fairness serves to establish what could be adequate, fair premiums. Accordingly, premiums paid by policyholders should match as closely as possible their risk exposure. Such premiums are the product (...) of the probabilities of losses and the expected losses. This article presents a discussion of the fairness of actuarial fairness through three steps: defining the concept based on its formulation within the insurance industry; determining in which sense it may be about fairness; and raising some objections to the actual fairness of actuarial fairness. The necessity of a normative evaluation of actuarial fairness is justified by the influence of the concept on the current reforms of public insurance systems and the fact that it highlights the question of the repartition of the gains and burdens of social cooperation.

Sometimes, a form of discrimination is hard to register, understand, and articulate. A rich precedent demonstrates how victim testimonies have been key in uncovering such “hidden” forms of discrimination, from sexual harassment to microaggressions. I reflect on how this plausibly goes too for “attentional discrimination”, referring to cases where the more meaningful attributes of one social group are made salient in attention in contrast to the less meaningful attributes of another. Victim testimonies understandably dominate the “context-of-discovery” stage of research into (...) these initially opaque forms of discrimination; a victim’s encounter with the gap between their experience and dominant conceptual frameworks for understanding it is what provides an initial foothold for analysis to begin. Some object, however, to this methodology continuing to dominate the later “context-of-justification” stage, where the hypothesis is rigorously challenged. I argue that this objection underestimates not just how other methodologies are more likely to inherit the various mechanisms of invisibility hiding the discrimination in question, but also how victim testimonies are distinctively well-suited to recognize and challenge those mechanisms. Victim testimonies, then, ought to continue playing a dominant role into these later stages of research regarding hidden forms of discrimination. (shrink)

Is there anything peculiarly bad about accepting moral testimony? According to pessimists, trusting moral testimony is an inadequate substitute for working out your moral views on your own. Enlightenment requires thinking for oneself, at least where morality is concerned. Optimists, by contrast, aim to show that trusting moral testimony isn’t bad largely by arguing that it’s no worse than trusting testimony generally. Essentially, they play defense. However, this chapter goes on the offensive. It explores two reasons (...) for thinking that trusting another person’s moral testimony is especially good. The first is an extended application of some of the lessons from recent discussions about epistemic injustice. The second, borrowing some cryptic epistemological thoughts from the young Marx, is that trusting another’s moral testimony is necessary for perfecting ourselves. It concludes that it can be better to accept moral testimony than to arrive at the same moral view on your own. (shrink)

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)

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)

The epistemology of testimony has experienced a growth in interest over the last twenty-five years that has been matched by few, if any, other areas of philosophy. _Testimony: A Philosophical Introduction _provides an epistemology of testimony that surveys this rapidly growing research area while incorporating a discussion of relevant empirical work from social and developmental psychology, as well as from the interdisciplinary study of knowledge-creation in groups. The past decade has seen a number of scholarly monographs on the (...) epistemology of testimony, but there is a dearth of books that survey the current field. This book fills that gap, assessing the strengths and weaknesses of all major competing theories. All chapters conclude with Suggestions for Further Reading and Discussion Questions. (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.

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.

The ArgumentHistorians of science naturally tend to express interest in other forms of intellectual activity only when these intersect with science. This tendncy has produced a number of enlightening studies of what happens when science and (for instance) law or theology come into contact, but little by way of how science enters into the calculations and social status of such forms of knowledge after the conjuction has passed. Recent work in the sociology of professions, in contrast, has focused attention precisely (...) on those moments when the expert knowledge produced by different group doesnotoverlap. This has been the contribution of Andrew Abbortt's theory of “jurisdictional boundaries” between competing professions. The case of Victorian actuaries who worked hard to maintain unique intellectual claims in the competitive life insurance industry while maintainiing strong social connections and overlaps in knowledge with organized science, challenges the way both historians of science and sociologists of professions view contending knowledge claims. By observing what motivated actuaries to forge an alliance with men of science in the 1820s, then tracing their gradual recognition of a need to distance themselves from certain of the “scientific” values that had earlier informed their collective identity, it is possible to make sense of connections as well as disconnections between science and other forms of knowledge. A history of quantification from the actuaries' perspective, in other words, allows us to view science bothasandincontext. (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)

The approach set forth by Edward Craig in Knowledge and the State of Nature has a greater explanatory value than it has been granted to date, and his suitably modified project can resolve a number of puzzling issues regarding the value of knowledge.

It is commonly claimed that reliance upon moral testimony is problematic in a way not common to reliance upon non-moral testimony. This chapter provides a new explanation of what the problem consists in—one that enjoys advantages over the most widely accepted explanation in the extant literature.

Aesthetic testimony is testimony about aesthetic properties. For example, in aone straightforward case, one person might tell another that something is beautiful. Philosophical discussion about aesthetic testimony centers on the question of whether there are any important differences between aesthetic testimony and testimony about non-aesthetic descriptive matters. In particular, the focus is often on the respective epistemic credentials of aesthetic and non-aesthetic testimony relative to firsthand judgments in the respective domains. Most are inclined to (...) think that in some way and to some degree we typically treat aesthetic testimony as being epistemically inferior to testimony about non-aesthetic matters. Assuming an asymmetry in the way we typically treat aesthetic and non-aesthetic testimony, the philosophical debate then asks a number of questions. Is aesthetic testimony actually epistemically inferior? If so, in what ways, and what explains its inferiority? If not, why do our ordinary ways of thinking, talking, and engaging with aesthetic testimony treat it as being inferior? In this chapter, I consider various ways in which experimental philosophy can contribute to these debates. Drawing on extant work and some new empirical studies, this chapter provides an overview of what experimental philosophy has told us so far, and summarizes the implications for philosophical debate.

The James Hardie case highlights structural issues in the employment of consulting actuaries which presents risks to the profession. It demonstrates that the combination of an aggressive corporate management with a strategic agenda reliant on consulting actuaries that have a vested interest in promoting and maintaining valuable relationships, both financially and professionally, results in ethical challenges.

We often talk about knowledge being transmitted via testimony. This suggests a picture of testimony with striking similarities to memory. For instance, it is often assumed that neither is a generative source of knowledge: while the former transmits knowledge from one speaker to another, the latter preserves beliefs from one time to another. These considerations give rise to a stronger and a weaker thesis regarding the transmission of testimonial knowledge. The stronger thesis is that each speaker in a (...) chain of testimonial transmission must know that p in order to pass this knowledge to a hearer. The weaker thesis is that at least the first speaker must know that p in order for any hearer in the chain to come to know that p via testimony. I argue that both theses are false, and hence testimony, unlike memory, can be a generative source of knowledge. (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)

We defend, from a contractarian perspective, that the fair price of an insurance policy is the amount that the contracting parties agree when they are both equally uncertain about the insured event. Drawing on the approach developed by R.

We show under which circumstances people can make fair actuarial agreements, without presupposing any objective risk or rationality benchmarks. (shrink)

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

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.

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.

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)

Testimony of oppression is testimony that something constitutes or contributes to a form of oppression, such as, for example, “The stranger’s comment was sexist.” Testimony of oppression that is given by members of the relevant oppressed group has the potential to play an important role in fostering a shared understanding of oppression. Yet, it is frequently dismissed out of hand. Against the background of a recent debate on moral testimony, this paper discusses the following question: How (...) should privileged hearers approach testimony of oppression if they aim to do so in an ethically and epistemically sound way? Should they defer or try to understand? Both strategies constitute ways of learning from testimony of oppression. However, they differ in important respects and exclude each other. Because testimony of oppression is often based on personal experience, empathizing with the speaker can play an important role in trying to understand testimony of oppression. While the fact that empathy can change your mind and the advantages of understanding over knowledge support trying to understand as the right approach to testimony of oppression, considerations of the “limits of empathy” and the value of deference support deferring. I argue that, on balance, these contrasting arguments allow for a limited defense of the role of empathy in learning from testimony of oppression. We should try to understand testimony of oppression by empathizing with the speaker, but not treat our ability to understand as a condition on accepting a speaker’s claim. (shrink)

What, if anything, is wrong with acquiring moral beliefs on the basis of testimony? Most philosophers think that there is something wrong with it, and most point to a special problem that moral testimony is supposed to create for moral agency. Being a good moral agent involves more than bringing about the right outcomes. It also involves acting with "moral understanding" and one cannot have moral understanding of what one is doing via moral testimony. And so, adherents (...) to this view claim, relying on moral testimony is problematic. Importantly, the problem that afflicts moral testimony, according to this view, is not a problem for testimonial knowledge in general. Indeed, critics of moral testimony acknowledge that a vast amount of our knowledge comes, completely unproblematically, from testimony. Call this the Asymmetry Thesis. We argue that while the diagnosis of what is wrong with moral testimony (when there is something wrong with it) in terms of moral understanding is correct, the lesson many of its adherents draw from it, namely that there is a principled difference between moral an non-moral testimony which renders the first, but not the second, problematic, is not. In other words, we argue that the Asymmetry Thesis is false. (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.

Addresses ‘too-odd-not-to-be-true’ reasoning in the assessment of testimony. This is the curious phenomenon that an initially less plausible report from multiple independent witnesses may elicit more confidence than an initially more plausible report.

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.
