Political epistemology is a newly flourishing area of philosophy, but there is no comprehensive overview to this burgeoning field. This chapter maps out the terrain of political epistemology, highlights some of the key questions and topics of this field, draws connections across seemingly disparate areas of work, and briefly situates this field within its historical and contemporary contexts.

We discuss the social-epistemic aspects of Catherine Elgin’s theory of reflective equilibrium and understanding and argue that it yields an argument for the view that a crucial social-epistemic function of epistemic authorities is to foster understanding in their communities. We explore the competences that enable epistemic authorities to fulfil this role and argue that among them is an epistemic virtue we call “epistemic empathy”.

This paper approaches the problem of testimony from a new direction. Rather than focusing on the epistemic grounds for testimony, it considers the problem from the perspective of an individual who must choose whom to trust from a population of many would-be testifiers. A computer simulation is presented which illustrates that in many plausible situations, those who trust without attempting to judge the reliability of testifiers outperform those who attempt to seek out the more reliable members of the community. In (...) so doing, it presents a novel defense for the credulist position that argues one should trust testimony without considering the underlying reliability of the testifier. (shrink)

The safety condition is supposed to be a necessary condition on knowledge which helps to eliminate epistemic luck. It has been argued that the condition should be globalized to a set of propositions rather than the target proposition believed to account for why not all beliefs in necessary truths are safe. A remaining issue is which propositions are relevant when evaluating whether the target belief is safe or not. In the literature, solutions have been proposed to determine the relevance of (...) propositions. This paper examines a case of luckily true belief—thus a case of ignorance—and a case of knowledge. It argues that no solution in the literature offers a correct verdict in either case. Therefore, the strategy to globalize safety remains unsatisfactory. (shrink)

To have a coherent picture of Wang Chong’s Lunheng is difficult. Some of Lunheng’s chapters obviously show Wang’s hostility to a large part of the folklore (including the social institutions based...

This paper explains how the notion of justification transmission can be used to ground a notion of knowledge transmission. It then explains how transmission theories can characterise schoolteacher cases, which have prominently been presented as counterexamples to transmission theories.

Pessimists about trust in the normative domain believe that forming normative beliefs on the basis of trusting others is problematic, forming normative beliefs in other ways is not so problematic and forming non-normative beliefs on the basis of trust is not so problematic. Whilst there is substantial disagreement over the best way of accounting for pessimist ideas about trust, it is widely accepted that the intuitively problematic character of forming normative beliefs on the basis of trust cannot be explained in (...) terms of the idea that trust cannot be a source of normative knowledge. This paper argues that the dismissal of scepticism about trust as a source of normative knowledge is unwarranted. It does so by developing a sceptical explanation of pessimist ideas, arguing that the obvious arguments against the sceptical explanation fail and arguing that the sceptical explanation has the resources to resolve the considerations that present problems for existing explanations.

Ernest Sosa has recently argued that the knowledge we get from instruments and the knowledge we get from testimony is similar in important ways. Most importantly, the justification that supports it is similar in kind – both instrumental justification and justification from testimony is to be understood in terms of reliability. I argue that Sosa’s theory is problematic. Specifically, I argue that we can take certain attitudes towards people that we cannot coherently take towards instruments. This, I argue, grounds a (...) distinction between the kind of justification that testimony can make available and the kind of justification that instruments can make available. The result is that reliability cannot provide a complete explanation of the justification that testimony makes available. (shrink)

According to some theories of testimonial knowledge, testimony can allow you, as a knowing speaker, to transmit your knowledge to me. A question in the epistemology of testimony concerns whether or not the acquisition of testimonial knowledge depends on the speaker's testimony being sincere. In this paper, I outline two notions of sincerity and argue that, construed in a certain way, transmission theorists should endorse the claim that the acquisition of testimonial knowledge requires sincerity.

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

According totransmissiontheories of testimony, a listener's belief in a speaker's testimony can be supported by the speaker's justification for what she says. The most powerful objection to transmission theories is Jennifer Lackey'spersistent believercase. I argue that important features about the epistemology of testimony reveal how transmission theories can account for Lackey's case. Specifically, I argue that transmission theorists should hold that transmission happens only if a listener believes a speaker's testimony based on the presumption that the speaker has justification for (...) what she says. If this does not happen in thepersistent believercase, then the case is no counterexample to transmission. If this does happen in thepersistent believercase, then there is an available framework for rejecting the idea that the listener's belief is in fact justified. (shrink)

According to internalist theories of testimony, beliefs based on what others say are justified by the reasons a listener uses in forming her belief. I identify a distinctive type of testimonial situation, which I call circular testimony and argue that a certain type of circular testimony establishes the incompleteness of internalist theories of testimony.

Many philosophers accept an ‘Authority Thesis’ according to which self-ascriptions of one’s current mental states ordinarily are or ought to be met with a distinctive presumption of truth. Recently, however, Wolfgang Barz (2018) has argued that there is no adequately specified Authority Thesis. This, he argues, is because available specifications are either (1) philosophically puzzling but implausible, or (2) plausible but philosophically unpuzzling. I argue that there are several plausible and philosophically puzzling specifications of the Authority Thesis.

It is raining but you don’t believe that it is raining. Imagine silently accepting this claim. Then you believe both that it is raining and that you don’t believe that it is raining. This would be an ‘absurd’ thing to believe,yet what you believe might be true. Itmight be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to believe something about yourself that might be (...) true of you? This is Moore’s paradox as it occurs in thought. Solving the paradox consists in explaining why such beliefs are absurd. I give a survey of some of the main explanations. I largely deal with explanations of the absurdity of ‘omissive’ beliefs with contents of the form p & I don’t believe that p and of ‘commissive beliefs’ with contents of the form p & I believe that not-p as well as beliefs with contents of the form p & I don’t know that p.

It is raining but you don’t believe that it is raining. Imagine accepting this claim. Then you are committed to saying ‘It is raining but I don’t believe that it is raining’. This would be an ‘absurd’ thing to claim or assert, yet what you say might be true. It might be raining, while at the same time, you are completely ignorant of the state of the weather. But how can it be absurd of you to assert something about yourself (...) that might be true of you? This is Moore’s paradox as it occurs in speech. What is the source of the absurdity? And why does it strike us that a contradiction is somehow at work when there is no contradiction in the content of what is asserted? In Section 2, I describe Moore’s formulation of the paradox and evaluate his own solutions. In Section 3, I discuss Wittgenstein’s inf luence in solving the paradox. In Section 4, I discuss Shoemaker’s priority thesis that once the absurdity in belief has been explained, then this will translate into an explanation of the absurdity in assertion. In Section 5, I discuss work on omissive and commissive Moore-paradoxical assertions, i.e. those of the forms p & I don’t believe that p and p & I believe that not-p. In Section 6, I discuss work on assertions of the form p & I don’t know that p. (shrink)

At the center of Gauker's book stands two inter-connected theses: First, that concepts are dependent on language; second, that this requires rejecting the traditional idea that linguistic communication involves a transmission of thoughts. I argue that we cannot afford to reject the traditional conception of communication and that Gauker's alternative ‘cooperative' conception is unsatisfactory. However, I also argue that Gauker is wrong to suggest that the language dependency thesis of concepts is incompatible with the traditional view of communication.

I argue that the rationale behind the fine-tuning argument for design is self-undermining, refuting the argument’s own premise that fine-tuning is to be expected given design. In (Weisberg 2010) I argued on informal grounds that this premise is unsupported. White (2011) countered that it can be derived from three plausible assumptions. But White’s third assumption is based on a fallacious rationale, and is even objectionable by the design theorist’s own lights. The argument that shows this, the argument from divine indifference, (...) simultaneously exposes the fine-tuning argument’s self-undermining character. The same argument also answers Bradley’s (forthcoming) reply to my earlier objection. (shrink)

I argue that what evidence an agent has does not supervene on how she currently is. Agents do not always have to infer what the past was like from how things currently seem; sometimes the facts about the past are retained pieces of evidence that can be the start of reasoning. The main argument is a variant on Frank Arntzenius’s Shangri La example, an example that is often used to motivate the thought that evidence does supervene on current features.

This article is an investigation into G. E. M. Anscombe's suggestion that there can be cases where belief takes a personal object, through an examination of the role that the activity of teaching plays in Anscombe's discussion. By contrasting various kinds of ‘teachers’ that feature in her discussion, it is argued that the best way of understanding the idea of believing someone personally is to situate the relevant encounter within the social, conversational framework of ‘engaged reasoning’. Key features of this (...) framework are highlighted, and are used to characterise the distinctive kind of teaching and learning germane to Anscombe's suggestion. (shrink)

The Assurance View, as advanced by Angus Ross and Richard Moran, makes the epistemology of testimony a matter of interpersonal commitments and entitlements. More specifically, I argue, their position is best understood as claiming that for someone’s belief to be testimonially justified is for some speaker to bear illocutionary responsibility for its truth. With this understanding in hand, I present a problem for the view that has so far escaped attention, a problem deriving from the wide freedom we have to (...) retract our assertions. Retraction dissolves the illocutionary responsibilities that were set up by preceding speech acts; but in some circumstances the epistemic significance of a retraction is effectively nil. We can therefore construct cases in which the responsibilities undertaken in testimony have been canceled, while the justification for belief based on it remains in place—and that shouldn’t be possible, if the Assurance View has things right. I present one such case and press its implications. (shrink)

This article argues for the thesis that the distinction between propositional and doxastic justification should be extended to knowledge. A consequence of this thesis is that there is a type of knowledge that requires belief and a type that does not. A familiar example strikingly similar to the sort of example used to introduce the propositional/doxastic justification makes a prima facie case. Additional theoretical advantages are revealed when the distinction is applied within the context of some recent epistemological debates. These (...) include debates over the knowledge account of assertion, testimonial knowledge, self-deception, and the question of whether knowledge can be essentially based on falsehood. It is contended that the sort of distinction offered here provides a way to settle these debates and, at the same time, acknowledge what is correct in the opposing positions. (shrink)

This paper argues that reading is a source of knowledge. Epistemologists have virtually ignored reading as a source of knowledge. This paper argues, first, that reading is not to be equated with attending to testimony, and second that it cannot be reduced to perception. Next an analysis of reading is offered and the source of knowledge that reading is further delineated. Finally it is argued that the source that reading is, can be both transmissive and generative, is non-basic, once was (...) a non-essential but has become essential for many people, and can be unique.

The paper is concerned with the epistemological status of testimony and the question of what may confer justification on true testimonial beliefs and enable us to call such beliefs knowledge. In particular, it addresses certain anti-reductionist arguments in the epistemology of testimony and their incompatibility with the grammatical categories of egophoricity (conjunct/disjunct marking) and evidentiality (information source marking) present in the architecture of natural languages. First, the tradition of epistemological individualism and its rationale are discussed, as well as certain attempts (...) within this tradition to include testimony-based beliefs in the body of legitimate and rational beliefs. The next section is concerned with the anti-reductionist approach to testimonial beliefs and some arguments supporting ‘the credulity principle’ grounded in Thomas Reid's philosophy of common sense. The last two sections show how the anti-reductionist argumentation is threatened with an insoluble dilemma when considered in the context of languages with the grammatical categories of egophoricity (conjunct/disjunct marking) and evidentiality (information source marking). Special attention is paid to the justificatory role of egophoric and evidential marking; how these grammatical categories may influence the process of belief formation, and consequently, how this bears upon the nature of justification for testimonial beliefs. The final conclusion of the paper is that the anti-reductionist claim concerning the directness and non-inferential nature of testimonial knowledge is bound to meet objections grounded in the structure of many natural languages. This leads to a paradox: in discussion with reductionism, anti-reductionists do seek support for their arguments in common sense beliefs reflected in everyday language, and, on the other hand, their claims are incompatible with the linguistic data found in a number of natural languages.

I argue against preservationism, the epistemic claim that memories can at most preserve knowledge generated by other basic types of sources. I show how memories can and do generate knowledge that is irreducible to other basic sources of knowledge. In some epistemic contexts, memories are primary basic sources of knowledge; they can generate knowledge by themselves or with trivial assistance from other types of basic sources of knowledge. I outline an ontology of information transmission from events to memory as an (...) alternative to causal theories of memory. I derive from information theory a concept of reliability of memories as the ratio of retrieved information to transmitted information. I distinguish the generation of knowledge from reliable memories from its generation from unreliable memories. Reliable memories can generate new knowledge by forming together narratives and via colligation. Coherent, even unreliable, memories can generate knowledge if they are epistemically independent of each other and the prior probability of the knowledge they generate is sufficiently low or high. Ascertaining the epistemic independence of memories and eliminating possible confounders may be achieved through the generation of knowledge from independent memories in different minds, when memories are primary basic sources of knowledge and the testimonies that report them are trivial.

In this paper, I explore what gives collective testimony its epistemic credentials, through a critical discussion of three competing accounts of the epistemology of collective testimony. According to the first view, collective testimony inherits its epistemic credentials from the beliefs the testimony expresses— where this can be seen either as the beliefs of all or some of the group’s members, or as the beliefs of group itself. The second view denies any necessary connection to belief, claiming instead that the epistemic (...) credentials of collective testimony derive from the reliability or truth-conduciveness of the statement that expresses the testimony. Finally, the third view claims that the epistemic credentials of collective testimony derive from the fact that it involves undertaking a collective commitment to trustworthiness, which makes the group susceptible to rebuke and blame if its testimony is not trustworthy. I argue that this last account holds the most promise for preserving what is distinctive about testimonial knowledge while still underwriting a robust epistemology of collective testimony. (shrink)

The very rules of our language games contain mechanisms of disregard. Philosophy of language tends to treat speakers as peers with equal discursive authority, but this is rare in real, lived speech situations. This paper explores the mechanisms of discursive inclusion and exclusion governing our speech practices, with a special focus on the role of gender attribution in undermining women’s authority as speakers. Taking seriously the metaphor of language games, we must ask who gets in the game and whose moves (...) can score. To do this, I develop an eclectic analysis of language games using basic inferential role theory and the concept of a semantic index, and develop the distinction between positional authority and expertise authority, which often conflict for members of oppressed groups. Introducing the concepts of master switches and sub-switches that attach to the index and change scorekeeping practices, I argue that women’s gender status conflicts with our status as authoritative speakers because sex marking in semantics functions as a master switch—“the F-switch”—on the semantic index, which, once thrown, changes the very game. An advantage of using inferentialism for understanding disregard of women’s discursive authority is that it locates the problem in the sanctioned moves, in the deontic structure of norms and practices of scorekeeping, and not primarily in the individual intentions of particular people.

This paper discusses the ways in which a person’s character ( ethos ) and a hearer’s emotional response ( pathos ) are part of the complex judgments made about experts’ claims, along with an actual assessment of those claims ( logos ). The analysis is rooted in the work of Aristotle, but expands to consider work on emotion and cognition conducted by Thagard and Gigerenzer. It also draws on some conclusions of the general epistemology of testimony (of which expert testimony (...) is a special subset), where it is argued that we learn not just from the transmission of another’s beliefs, but from the words they speak. This shifts the onus in testimony away from the intentions of a speaker onto the judgments of an audience, capturing better its social character and reflecting our experience of receiving testimony. I conclude, however, that accepting the arguments of experts involves much more than simply believing what they say. (shrink)

This article discusses recent work on lying and its relation to deceiving and misleading. Two new developments in this area are considered: first, the acknowledgment of the phenomenon of lying without the intent to deceive , and second, recent work on the distinction between lying and merely misleading. Both are discussed in relation to topics in philosophy of language, the epistemology of testimony, and ethics. Critical surveys of recent theories are offered and challenges and open questions for further research are (...) indicated. (shrink)

This paper has two aims: it develops and defends a fully-fledged account of the epistemic normativity of conjecture it goes sharply against orthodoxy, in arguing that conjecture is epistemically more demanding than assertion. According to the view defended here, one’s conjecture that p is permissible only if one knows that one has warrant, but not sufficient warrant to believe that p. I argue for my account on three independent grounds: the Bach and Harnish account of the nature of communicative speech (...) acts, the plausible normative relation between assertion and other constatives, and the normativity of belief in conjunction with constatives’ epistemic function.

In recent years, much attention has been given to the epistemic credentials of belief based on moral testimony. Some people think pure moral deference is wrong, others disagree. It comes as a surprise, however, that while the epistemic responsibilities of the receiver of moral testimony have been closely scrutinized, little to no discussion has focused on the epistemic duties of the speaker. This paper aims to supply this lack: it defends a function-first account of the normativity of moral assertion. According (...) to this view, in virtue of its function of reliably generating understanding in the audience, a moral assertion that p needs be knowledgeable and accompanied by a contextually appropriate explanation why p.

Cognitivism about trust says that it requires belief that the trusted is trustworthy; non-cognitivism denies this. At stake is how to make sense of the strong but competing intuitions that trust is an attitude that is evaluable both morally and rationally. In proposing that one's respect for another's agency may ground one's trusting beliefs, second-personal accounts provide a way to endorse both intuitions. They focus attention on the way that, in normal situations, it is the person whom I trust. My (...) task is to develop an account of the latter insight without the controversial theoretical commitments of the former. I propose a functional account for why the second and third-personal ‘systems’ operate not just in parallel, but in tandem, in support of a cognitivist account of trust. (shrink)

One very popular assumption in the epistemological literature is that belief and assertion are governed by one and the same epistemic norm. This paper challenges this claim. Extant arguments in defence of the view are scrutinized and found to rest on value-theoretic inaccuracies. First, the belief-assertion parallel is shown to lack the needed normative strength. Second, I argue that the claim that assertion inherits the norm of belief in virtue of being an expression thereof rests on a failed instance of (...) deontic transmission. Third, the inheritance argument from the norm for action is proven guilty of deontic equivocation. Last but not least, it is argued that, on a functionalist normative picture, assertion and belief are governed by different epistemic norms, in virtue of serving different epistemic functions. (shrink)

DeRose famously argued that, given that assertability varies with practical context, we cannot combine a biconditional knowledge norm of assertion with classical invariantism. The first aim of this paper is to show that De Rose's argument is ultimately unsuccessful. Second, I develop a view, entitled Assertion Functionalism, which combines the knowledge norm with classical invariantism and at the same time offers an appealing account of the intuitive variability of proper assertion.

In this article, I argue that the nature of testimony necessitates that we distinguish between testimonies that are based on the informant's sense perception, inference, or on a longer testimonial chain. I further argue that this distinction has epistemic significance, in that it helps us better understand how reliable certain classes of testimonies are and how reliable certain individuals are, based upon the epistemic source that their testimony is ultimately grounded in. I begin the article, in Section 1, by drawing (...) attention to the existence of several different terms for testimony found within the Islamic philosophical tradition. In Section 2, I argue that the essential difference between these terms has to do with the epistemic source that grounds the speaker’s testimony. In Section 3, I move on to explicate how this distinction helps us better understand the reliability of testimony and how it impacts our evaluation of the reliability of different speakers in different contexts. In Section 4, I use this distinction to challenge the necessary condition of speaker competency. Finally, in Section 5, I use the distinction to undermine the belief-transmission view in the epistemology of testimony. (shrink)

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

ABSTRACT The contemporary epistemological debate regarding the epistemic role of memory is dominated by the dispute between two different views: memory preservationism and memory generativism. While the former holds that memory only preserves the epistemic status already acquired through another source, the latter advocates that there are situations where memory can function as a generative epistemic source. Both views are problematic and have to deal with important objections. In this paper, I suggest a novel argument for granting memory the status (...) of a generative source of justification and knowledge that overcomes objections raised for both preservationism and generativism. I shall call this view Memory Compatibilism. I argue that the proposed view better explains the generative epistemic character of memory.RESUMO O debate epistemológico contemporâneo acerca do papel epistêmico da memória tem sido dominado pela disputa entre duas visões diferentes: o preservacionismo da memória e o gerativismo da memória. Enquanto o primeiro sustenta que a memória apenas preserva o status epistêmico já adquirido via outra fonte, o último defende que existem situações em que a memória pode funcionar como uma fonte epistêmica geradora. Ambas as visões são problemáticas e têm de lidar com objeções importantes. Neste artigo, sugiro um novo argumento para conceder à memória o status de fonte geradora de justificação e conhecimento que supera as objeções levantadas contra o preservacionismo e o geracionismo. Chamarei esta visão de compatibilismo da memória. Argumento que a visão proposta melhor explica o caráter epistêmico gerativo da memória. (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.

Unusability pessimism has recently emerged as an appealing new option for pessimists about aesthetic testimony—those who deny the legitimacy of forming aesthetic beliefs on the basis of testimony. Unusability pessimists argue that we should reject the traditional pessimistic stance that knowledge of aesthetic matters is unavailable via testimony in favour of the view that while such knowledge is available to us, it is unusable. This unusability stems from the fact that accepting such testimony would violate an important non-epistemic norm of (...) belief formation. In this article I present an objection to unusability pessimism and argue that Robert Hopkins, the view's most prominent defender, fails to motivate adequately the claim that there are such non-epistemic belief norms. The cases which putatively legitimize usability norms can be explained by appeal to more familiar norm types: epistemic norms of belief formation, and non-epistemic norms which govern action other than belief formation. The intent of this article is not primarily negative, however, and I will also argue that understanding why the unusability position fails helps us to identify a promising new direction for the pessimist's opponents who wish to defend the legitimacy of forming aesthetic beliefs on the basis of testimony.

We investigate how epistemic injustice can manifest itself in mathematical practices. We do this as both a social epistemological and virtue-theoretic investigation of mathematical practices. We delineate the concept both positively—we show that a certain type of folk theorem can be a source of epistemic injustice in mathematics—and negatively by exploring cases where the obstacles to participation in a mathematical practice do not amount to epistemic injustice. Having explored what epistemic injustice in mathematics can amount to, we use the concept (...) to highlight a potential danger of intellectual enculturation. (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)

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. (shrink)
