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.

Testimony is an invaluable source of knowledge. We rely on the reports of those around us for everything from the ingredients in our food and medicine to the identity of our family members. Recent years have seen an explosion of interest in the epistemology of testimony. Despite the multitude of views offered, a single thesis is nearly universally accepted: testimonial knowledge is acquired through the process of transmission from speaker to hearer. In this book, Jennifer Lackey shows that (...) this thesis is false and, hence, that the literature on testimony has been shaped at its core by a view that is fundamentally misguided. She then defends a detailed alternative to this conception of testimony: whereas the views currently dominant focus on the epistemic status of what speakers believe, Lackey advances a theory that instead centers on what speakers say. The upshot is that, strictly speaking, we do not learn from one another's beliefs - we learn from one another's words. Once this shift in focus is in place, Lackey goes on to argue that, though positive reasons are necessary for testimonial knowledge, testimony itself is an irreducible epistemic source. This leads to the development of a theory that gives proper credence to testimony's epistemologically dual nature: both the speaker and the hearer must make a positive epistemic contribution to testimonial knowledge. The resulting view not only reveals that testimony has the capacity to generate knowledge, but it also gives appropriate weight to our nature as both socially indebted and individually rational creatures. The approach found in this book will, then, represent a radical departure from the views currently dominating the epistemology of testimony, and thus is intended to reshape our understanding of the deep and ubiquitous reliance we have on the testimony of those around us.

there seems to be some kind of asymmetry, at least in some cases, between moral testimony and non-moral testimony, between aesthetic testimony and non-aesthetic testimony, and between religious testimony and non-religious testimony. In these domains, at least in some cases, we object to deference, and for this reason expect people to form their beliefs on non-testimonial grounds, in a way that we do not object to deference in paradigm cases of testimonial knowledge. Our philosophical (...) puzzle is therefore: what explains these (apparent) asymmetries (or are they merely apparent)? My aim here is to criticize three accounts of these testimonial asymmetries and to suggest an alternative strategy for solving our puzzle. I’ll consider the idea that testimony cannot be a source of understanding (§2), the idea that testimony cannot be a source of acquaintance (§3), and the idea that testimonial belief is not conducive to moral virtue (§4). These accounts all explain the badness of testimonial belief, in the relevant cases, by appeal to its consequences for the believer—respectively, a lack of understanding, acquaintance, or moral virtue. I’ll conclude by suggesting a way forward (§5): we should try to understand the badness of testimonial belief, in the relevant cases, as deriving from its consequences for the believer’s society.

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)

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.

Testimony is a crucial source of knowledge: we are to a large extent reliant upon what others tell us. It has been the subject of much recent interest in epistemology, and this volume collects twelve original essays on the topic by some of the world's leading philosophers. It will be the starting point for future research in this fertile field. Contributors include Robert Audi, C. A. J. Coady, Elizabeth Fricker, Richard Fumerton, Sanford C. Goldberg, Peter Graham, Jennifer Lackey, Keith (...) Lehrer, Richard Moran, Frederick F. Schmitt, Ernest Sosa, and James Van Cleve. (shrink)

In this paper, I develop two criticisms of Miranda Fricker’s attempt to offer an interpretation of MacKinnon’s claim that pornography silences women that conceives of the silencing in question as an extreme form of testimonial injustice. The intended contrast is with the speech act theoretical model of silencing familiar from Rae Langton and Jennifer Hornsby, who appeal to MacKinnon’s claim to argue against the standard liberal line on pornography, which takes a permissive stance to be demanded by a right to (...) freedom of speech. Fricker’s alternative suggestion is that women are the victims of ‘an especially acute form of testimonial injustice’, due to the kind of dehumanizing bad sexual ideology peddled in much pornography. Fricker suggests that both notions of silencing are coherent possibilities, but that ‘the epistemic model describes the more empirically likely possibility, simply because it requires less erosion of women’s human status before the silencing effect kicks in’. I question the truth of this advertised advantage of Fricker’s epistemic account of silencing, but also its relevance to philosophical debates about pornography and silencing. Second, I raise a concern about theorizing about sexual refusal as a kind of testimony, as Fricker does. (shrink)

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. The main theses of the chapter are as follows: that many forms of normative deference beyond the moral are problematic, that there is a common explanation of the problem with all of these (...) forms of deference—an explanation that is based on the connection between the relevant judgments and desire-like attitudes, and that this explanation is compatible with moral realism. (shrink)

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)

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)

I set out an argument for religious fictionalism which, unusually, proceeds from realist assumptions to the conclusion that even though some people might know that God exists, others ought to accept only non-doxastically that God exists. The argument relies upon the idea that religious experiences can confer immediate warrant on religious beliefs, whereas the warrant conferred by testimony is defeated by some reasonable beliefs which many people have.

A person sometimes forms moral beliefs by relying on another person''s moral testimony. In this paper I advance a cognitivist normative account of this phenomenon. I argue that for a person''s actions to be morally good, they must be based on a recognition of the moral reasons bearing on action. Morality requires people to act from an understanding of moral claims, and consequently to have an understanding of moral claims relevant to action. A person sometimes fails to meet this (...) requirement when she relies on another person''s moral testimony, and so there are moral limits on such reliance. (shrink)

Testimony is an important source of our knowledge about the world. But to some, there seems something odd, perhaps even wrong, about trusting testimony about specifically moral matters. In this paper, I discuss several different explanations of what might be wrong with trusting moral testimony. These include the possibility that there is no moral knowledge; that moral knowledge cannot be transmitted by moral testimony; that there are reasons not to trust moral testimony either because you (...) should try to gain and use “moral understanding” to make your moral judgements instead or because doing so is damaging to your moral character in various ways. Finally, I discuss some “debunking explanations” according to which it is right and rational to trust moral testimony from a trustworthy source. © 2013 The Author.

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)

Much of what we learn from talking and listening does not qualify as testimonial knowledge: we can learn a great deal from other people without simply accepting what they say as being true. In this article, I examine the ways in which we acquire skills or knowledge how from our interactions with other people, and I discuss whether there is a useful notion of testimonial knowledge how.Keywords: Knowledge how; Practical knowledge; Tacit knowledge; Testimony; Skills; Assertion.

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

In 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)

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.

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)

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)

This paper considers a special case of belief updating—when an agent learns testimonial data, or in other words, the beliefs of others on some issue. The interest in this case is twofold: (1) the linear averaging method for updating on testimony is somewhat popular in epistemology circles, and it is important to assess its normative acceptability, and (2) this facilitates a more general investigation of what it means/requires for an updating method to have a suitable Bayesian representation (taken here (...) as the normative standard). The paper initially defends linear averaging against Bayesian-compatibility concerns raised by Bradley (Soc Choice Welf 29:609-632, 2007), as well as problems associated with multiple testimony updates. The resolution of these issues, however, requires an extremely nuanced interpretation of the parameters of the linear averaging model—the so-called weights of respect. We go on to propose a role that the parameters of any 'shortcut' updating function should play, by way of minimal interpretation of these parameters. The class of updating functions that is consistent with this role, however, excludes linear averaging, at least in its standard form. (shrink)

Miranda Fricker has influentially discussed testimonial injustice: the injustice done to a speaker S by a hearer H when H gives S less-than-merited credibility. Here, I explore the prospects for a novel form of testimonial injustice, where H affords S due credibility, that is, the amount of credibility S deserves. I present two kinds of cases intended to illustrate this category, and argue that there is presumptive reason to think that testimonial injustice with due credibility exists. I show that if (...) it is denied that ultimately these cases exemplify testimonial injustice without credibility deficit, then either they must be taken to exemplify a novel kind of epistemic, non-testimonial injustice, or they bring to light a significant exegetical result.

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

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.

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.

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)

Many philosophers believe that there exist distinctive obstacles to relying on moral testimony. In this paper, I criticize previous attempts to identify these obstacles and offer a new theory. I argue that the problems associated with moral deference can't be explained in terms of the value of moral understanding, nor in terms of aretaic considerations related to subjective integration. Instead, our uneasiness with moral testimony is best explained by our attachment to an ideal of authenticity that places special (...) demands on our moral beliefs. (shrink)

Testimony is the mainstay of human communication and essential for the spread of knowledge. But testimony may also spread error. Under what conditions does it yield knowledge in the person addressed? Must the recipient trust the attester? And does the attester have to know what is affirmed? A related question is what is required for the recipient to be justified in believing testimony. Is testimony-based justification acquired in the same way as testimony-based knowledge? This paper (...) addresses these and other questions. It offers a theory of the role of testimony in producing knowledge and justification, a sketch of a conception of knowledge that supports this theory, a brief account of how trust of others can be squared with critical habits of mind, and an outline of some important standards for intellectual responsibility in giving and receiving testimony.

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.

In this paper I argue that there can be cases of testimonial knowledge acquired through the acceptance of testimony which itself is unsafe. This has implications both for the epistemology of testimony and for the social nature of knowledge more generally.

Testimony/Bearing Witness establishes a dialogue between the different approaches to testimony in epistemology, historiography, law, art, media studies and psychiatry.

In light of recent social psychological literature, I expand Miranda Fricker’s important notion of testimonial injustice. A fair portion of Fricker’s account rests on an older paradigm of stereotype and prejudice. Given recent empirical work, I argue for what I dub prescriptive credibility deficits in which a backlash effect leads to the assignment of a diminished level of credibility to persons who act in counter-stereotypic manners, thereby flouting prescriptive stereotypes. The notion of a prescriptive credibility deficit is not merely an (...) interesting conceptual addendum that can be appended to Fricker’s theory without need for further emendation. I develop the wider implications of prescriptive credibility deficits and argue that they pose a challenge to Fricker’s conception of the function of credibility assignments in conversational exchange and how a virtuous listener should respond to the potential threat of a prejudicial stereotype affecting her credibility assignments.

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.

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

The thesis that aesthetic testimony cannot provide aesthetic justification or knowledge is widely accepted--even by realists about aesthetic properties and values. This Kantian position is mistaken. Some testimony about beauty and artistic value can provide a degree of aesthetic justification and, perhaps, even knowledge. That is, there are cases in which one can be justified in making an aesthetic judgment purely on the basis of someone else's testimony. But widespread aesthetic unreliability creates a problem for much aesthetic (...) testimony. Hence, most testimony about art does not have much epistemic value. The situation is somewhat different with respect to aesthetic testimony about nature, proofs, and theories. (shrink)

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

Various considerations are adduced toshow that we require that a testifier know hertestimony. Such a requirement apparentlyimproves testimony. It is argued that the aimof improving testimony explains why we have anduse our concept of knowledge.

We often rely on others for guidance about what to do. But wouldn't it be better to rely instead on only your own solo judgment? Deferring to others about moral matters, after all, can seem to conflict what Enlightenment demands. In Guided by Voices, however, Eric Wiland argues that there is nothing especially bad about relying on others in forming your moral views. You may rely on others for forming your moral views, just as you can your views about anything (...) else. You can accept moral testimony without loss. Furthermore, there are several distinctive social goods attainable by being guided by what others say. Thus, it can be better to be guided by moral testimony than by your own moral lights. Wiland also argues that relying on others for moral advice has one advantage over relying on others for moral testimony. For when you trust your adviser's advice, you both thereby form a joint agent that can achieve autonomy, moral understanding, and morally worthy action. Sometimes taking another's advice is your only way to act well. Arguing against the presumption that moral reasoning is ideally done alone, Guided by Voices is the first book to significantly address both moral testimony and advice. (shrink)

The problem of explaining how we acquire knowledge via testimony gives rise to a dilemma, according to which any theory must make testimonial knowledge either too hard or too easy, and therefore no adequate account of testimonial knowledge is possible. In recent work, John Greco offers a solution to the dilemma on behalf of anti-reductionism that appeals to Edward Craig’s functionalist epistemology. It is argued that Greco’s solution is flawed, in that his functionalist account provides wrong verdicts of ordinary (...) cases of testimonial knowledge. In contrast, it is shown that both anti-reductionism and reductionism have the resources to solve the dilemma and provide the right verdicts in ordinary cases of testimonial knowledge without appealing to Greco’s functionalism.
