If the reliability of a source of testimony is open to question, it seems epistemically illegitimate to verify the source’s reliability by appealing to that source’s own testimony. Is this because it is illegitimate to trust a questionable source’s testimony on any matter whatsoever? Or is there a distinctive problem with appealing to the source’s testimony on the matter of that source’s own reliability? After distinguishing between two kinds of epistemically illegitimate circularity—bootstrapping and self-verification—I argue for a qualified version of (...) the claim that there is nothing especially illegitimate about using a questionable source to evaluate its own reliability. Instead, it is illegitimate to appeal to a questionable source’s testimony on any matter whatsoever, with the matter of the source’s own reliability serving only as a special case. (shrink)

Recent interest in the epistemology of testimony can be traced to C. A. J. Coady's Testimony: A Philosophical Study (1992) and then a collection of papers edited by Bimal Krishna Matilal and Arindam Chakrabarti, Knowing from Words (1994). These two volumes framed several issues in the epistemology of testimony and largely set the agenda for work in that area over the next two decades. -/- One major issue in this literature is whether testimonial knowledge can be "reduced" to some other (...) kind of knowledge: Is testimonial knowledge sui generis, requiring its own distinctive treatment, or is testimonial knowledge merely an instance of, for example, inductive knowledge, requiring no special epistemology over and above that required for inductive knowledge in general? One way that testimonial knowledge might be special is that it involves social elements that make it distinctive. This possibility raises further issues that have been prominent in the literature: In what ways is testimonial knowledge a social phenomenon, and what are the consequences of this for the epistemology of testimony and for epistemology more generally?

According to assurance views of testimonial justification, in virtue of the act of testifying a speaker provides an assurance of the truth of what she asserts to the addressee. This assurance provides a special justificatory force and a distinctive normative status to the addressee. It is thought to explain certain asymmetries between addressees and other unintended hearers (bystanders and eavesdroppers), such as the phenomenon that the addressee has a right to blame the speaker for conveying a falsehood but unintended hearers (...) do not, and the phenomenon that the addressee may deflect challenges to his testimonial belief to the speaker but unintended hearers may not. Here I argue that we can do a better job explaining the normative statuses associated with testimony by reference to epistemic norms of assertion and privacy norms. Following Sanford Goldberg, I argue that epistemic norms of assertion, according to which sincere assertion is appropriate only when the asserter possesses certain epistemic goods, can be ‘put to work’ to explain the normative statuses associated with testimony. When these norms are violated, they give hearers the right to blame the speaker, and they also explain why the speaker takes responsibility for the justification of the statement asserted. Norms of privacy, on the other hand, directly exclude eavesdroppers and bystanders from an informational exchange, implying that they have no standing to do many of the things, such as issue challenges or questions to the speaker, that would be normal for conversational participants. This explains asymmetries of normative status associated with testimony in a way logically independent of speaker assurance. (shrink)

Many virtual communities that rely on user-generated content (such as social news sites, citizen journals, and encyclopedias in particular) offer unrestricted and immediate ‘write access’ to every contributor. It is argued that these communities do not just assume that the trust granted by that policy is well-placed; they have developed extensive mechanisms that underpin the trust involved (‘backgrounding’). These target contributors (stipulating legal terms of use and developing etiquette, both underscored by sanctions) as well as the contents contributed by them (...) (patrolling for illegal and/or vandalist content, variously performed by humans and bots; voting schemes). Backgrounding trust is argued to be important since it facilitates the avoidance of bureaucratic measures that may easily cause unrest among community members and chase them away. (shrink)

Michael Huemer () argues that following the epistemic strategy of Critical Thinking—that is, thinking things through for oneself—leaves the agent epistemically either worse off or no better off than an alternative strategy of Credulity—that is, trusting the authorities. Therefore, Critical Thinking is not epistemically responsible. This article argues that Reasonable Credulity entails Critical Thinking, and since Reasonable Credulity is epistemically responsible, the Critical Thinking that it entails is epistemically responsible too.

The Linda paradox is a key topic in current debates on the rationality of human reasoning and its limitations. We present a novel analysis of this paradox, based on the notion of verisimilitude as studied in the philosophy of science. The comparison with an alternative analysis based on probabilistic confirmation suggests how to overcome some problems of our account by introducing an adequately defined notion of verisimilitudinarian confirmation.

The ideas behind open source software are currently applied to the production of encyclopedias. A sample of six English text-based, neutral-point-of-view, online encyclopedias of the kind are identified: h2g2, Wikipedia, Scholarpedia, Encyclopedia of Earth, Citizendium and Knol. How do these projects deal with the problem of trusting their participants to behave as competent and loyal encyclopedists? Editorial policies for soliciting and processing content are shown to range from high discretion to low discretion; that is, from granting unlimited trust to limited (...) trust. Their conceptions of the proper role for experts are also explored and it is argued that to a great extent they determine editorial policies. Subsequently, internal discussions about quality guarantee at Wikipedia are rendered. All indications are that review and ?super-review? of new edits will become policy, to be performed by Wikipedians with a better reputation. Finally, while for encyclopedias the issue of organizational trust largely coincides with epistemological trust, a link is made with theories about the acceptance of testimony. It is argued that both non-reductionist views (the ?acceptance principle? and the ?assurance view?) and reductionist ones (an appeal to background conditions, and a?newly defined??expertise view?) have been implemented in editorial strategies over the past decade.

In this paper I use philosophical accounts on the relationship between trust and knowledge in science to apprehend this relationship on the Web. I argue that trust and knowledge are fundamentally entangled in our epistemic practices. Yet despite this fundamental entanglement, we do not trust blindly. Instead we make use of knowledge to rationally place or withdraw trust. We use knowledge about the sources of epistemic content as well as general background knowledge to assess epistemic claims. Hence, although we may (...) have a default to trust, we remain and should remain epistemically vigilant; we look out and need to look out for signs of insincerity and dishonesty in our attempts to know. A fundamental requirement for such vigilance is transparency: in order to critically assess epistemic agents, content and processes, we need to be able to access and address them. On the Web, this request for transparency becomes particularly pressing if (a) trust is placed in unknown human epistemic agents and (b) if it is placed in non-human agents, such as algorithms. I give examples of the entanglement between knowledge and trust on the Web and draw conclusions about the forms of transparency needed in such systems to support epistemically vigilant behaviour, which empowers users to become responsible and accountable knowers.

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

Le projet philosophique puise ses sources dans la volonté de proposer une explication rationnelle des phénomènes naturels et culturels qui constituent le monde dans lequel l’être humain prend place. Il a servi de trame culturelle à l’Occident et amené le déploiement d’appareils conceptuels où l’on distingue théorie et pratique. On doit toutefois reconnaître qu’une philosophie théorique peut avoir une portée pratique et l’inverse, puisque toute pratique suppose un ancrage théorique pour légitimer la connaissance et les systèmes normatifs à partir desquels (...) les explications sont avancées. Cela fait dire à certains que la distinction est désormais surannée et qu’une théorie philosophique réunifiée s’impose. Que l’on soit tenant de la tradition ou des nouvelles approches, la philosophie pratique s’impose désormais comme un passage obligé pour réfléchir les problèmes et articuler de nouvelles théories faisant écho à l’état actuel de notre monde. Le présent ouvrage revient sur la notion de philosophie pratique afin d’en faire voir les différentes acceptions et manières de la mobiliser pour réfléchir à des problèmes actuels. (shrink)

According to an influential view, asserting a proposition involves undertaking some “commitment” to the truth of that proposition. But accounts of what it is for someone to be committed to the truth of a proposition are often vague or imprecise, and are rarely put to work to define assertion. This paper aims to fill this gap. It offers a precise characterisation of assertoric commitment, and shows how it can be applied to define assertion. On the proposed view, acquiring commitment is (...) not sufficient for asserting. To assert, commitment must be acquired by explicitly presenting a proposition as true. (shrink)

Matthew McGrath has recently challenged all theories that allow for immediate perceptual justification. This challenge comes by way of arguing for what he calls the “Looks View” of visual justification, which entails that our visual beliefs that are allegedly immediately justified are in fact mediately justified based on our independent beliefs about the looks of things. This paper shows that McGrath’s arguments are unsound or, at the very least, that they do not cause genuine concern for the species of dogmatism (...) called “Phenomenal Explanationism”, recently introduced and defended by Kevin McCain and Luca Moretti.

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

This paper articulates a general distinction between two important communicative ideals—expressive sincerity and discursive integrity—and then uses it to analyze problems with political debate in contemporary democracies. In the context of philosophical discussions of different forms of trustworthiness and debates about deliberative democracy, self-knowledge, and moral testimony, the paper develops three arguments for the conclusion that, although expressive sincerity is valuable, we should not ignore discursive integrity in thinking about how to address problems with contemporary political debate. The paper concludes (...) with a brief discussion of a strategy for improving discursive integrity within public political debate by reflecting on which principles of responsible public debate would promote better democratic decision making.

People are often offended by beliefs, expect apologies for beliefs, apologize for their own beliefs. In many mundane cases, people are morally criticized for their beliefs. Intuitively, then, beliefs seem to sometimes wrong people. Recently, the philosophical literature has picked up on this theme, and has started to discuss it under the heading of doxastic wrongdoing. In this paper we argue that despite the strength of such initial intuitions, at the end of the day they have to be rejected. If (...) it can be ever truthfully asserted that beliefs wrong, this is always derivative – beliefs wrong only in virtue of other things (like evidence-gathering actions) wronging. We distinguish between modest and ambitious doxastic wrongdoing theories (the former deny, while the latter accept, the possibility of a morally wrong yet epistemically permissible belief); we argue that each of these options faces insurmountable problems; and we offer partly debunking explanations of the intuitions purportedly supporting doxastic wrongdoing.

Social knowledge, for the most part, is knowledge through testimony. This essay is an overview of the epistemology of testimony. The essay separates knowledge from justification, characterizes testimony as a source of belief, explains why testimony is a source of knowledge, canvasses arguments for anti-reductionism and for reductionism in the reductionism vs. anti-reductionism debate, addresses counterexamples to knowledge transmission, defends a safe basis account of testimonial knowledge, and turns to social norms as a partial explanation for the reliability of testimony.

Epistemic injustice is injustice to a person qua knower. In one form of this phenomenon a speaker’s testimony is denied credence in a way that wrongs them. I argue that the received definition of this testimonial injustice relies too heavily on epistemic criteria that cannot explain why the moral concept of injustice should be invoked. I give an account of the nature of the wrong of epistemic injustice that has it depend not on the accuracy of judgments that are used (...) or made in the process of deciding whether to listen to or trust a speaker, but on whether the basis of the decision about a speaker is their reliability or their identity, and the account explains why the latter is a moral wrong. A key difference between the two accounts is how they classify the use of true statistical generalizations connecting identity and reliability. The received view implies that this cannot be an injustice, while the view proposed here implies that it can. As such the new view appears to imply a conflict between moral and epistemic obligations: it is morally wrong to use true statistical generalizations in certain contexts, yet they are part of our evidence, and we are epistemically obligated to take all of our evidence into account. I reconcile these two thoughts without adopting the currently popular view that a belief’s being morally wrong makes it epistemically unjustified, and I argue that following the principle of total evidence encourages epistemic justice rather than thwarting it.

Introduction to Philosophy: Epistemology engages first-time philosophy readers on a guided tour through the core concepts, questions, methods, arguments, and theories of epistemology—the branch of philosophy devoted to the study of knowledge. After a brief overview of the field, the book progresses systematically while placing central ideas and thinkers in historical and contemporary context. The chapters cover the analysis of knowledge, the nature of epistemic justification, rationalism vs. empiricism, skepticism, the value of knowledge, the ethics of belief, Bayesian epistemology, social (...) epistemology, and feminist epistemologies. Along the way, instructors and students will encounter a wealth of additional resources and tools: chapter learning outcomes, key terms, images of philosophers and related art, useful diagrams and tables, boxes containing excerpts and other supplementary material, questions for reflection, suggestions for further reading, and a glossary. For an undergraduate survey epistemology course, Introduction to Philosophy: Epistemology is ideal when used as a main text paired with primary sources and scholarly articles. For an introductory philosophy course, select book chapters are best used in combination with chapters from other books in the Introduction to Philosophy open textbook series (edited by Christina Hendricks).

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 paper offers a brief survey of the philosophical literature on assertion, presenting each contribution to the RIFL special issue "Assertion and its social significance" within the context of the contemporary debate in which it intervenes. The discussion is organised into three thematic sections. The first one concerns the nature of assertion and its relation with assertoric commitment – the distinctive responsibility that the speaker undertakes in virtue of making a statement. The second section considers the epistemic significance of assertion, (...) exploring the role that assertion plays in the transmission of knowledge, the epistemic constraints that regulate it, and its relation with truth. The third section deals with communicative content that goes beyond what is literally asserted: implicatures, metaphors and expressive meaning. (shrink)

According to evidentialism, a belief is propositionally justified just in case it fits one’s evidence. A fully developed evidentialist theory of justification will require an account of the evidential fit relation. Some evidentialists have embraced an explanationist account of this relation. Some of these accounts, such as Kevin McCain’s, place an awareness requirement on evidential fit. That is, they claim that a proposition, p, fits a subject’s evidence, e, only if the subject is aware of the explanatory connection between p (...) and e. I argue by way of example that this version of explanationism fails. As a result, I suggest a friendly revision of explanationism that excludes an awareness condition. Finally, I field some objections to my version of explanationism. (shrink)

Who should be the author(s) of an academic paper? This question is becoming increasingly pressing, due to the increasing prevalence and scale of scientific collaboration, and the corresponding diversity of authorship practices in different disciplines and subdisciplines. This paper addresses the conceptual issues underlying authorship, with an eye to ameliorating authorship practices. The first part of the paper distinguishes five roles played by authorship attributions: allocating credit, constructing a speaker, enabling credibility judgements, supporting accountability, and creating an intellectual marketplace. The (...) second part of the paper argues that distinguishing these functions helps us see that at least some of the confusions around authorship are due to tensions between these functions. The final part of the paper suggests a way to resolve these conceptual confusions, which we will call the CSWG proposal. This proposal suggests replacing authorship with a bundle of roles tailored to the functions of authorship—contributor, spokesperson, writer, and guarantor—which can be distributed in a number of different ways.

In Part I of “Of Miracles,” Hume argues that belief in miracle-testimony is never justified. While Hume’s argument has been widely criticized and defended along a number of different veins, including its import on scientific inquiry, this paper takes a novel approach by comparing Hume’s argument with Thomas Kuhn’s account of scientific anomalies. This paper makes two arguments: first that certain types of scientific anomalies—those that conflict with the corresponding paradigm theory—are analogous to miracles in the relevant ways. Note, importantly, (...) that the argument applies only to the first definition of ‘miracle’ that Hume offers Second, it argues that we are sometimes rationally justified in believing testimony for scientific anomalies, because there have been several cases of scientists accepting such anomalies and—assuming certain criteria are met—we are rationally justified in believing these scientists. If both arguments are successful, then it is possible to be rationally justified in believing miracle-testimony, though the extent of justification depends on various criteria and comes in degrees. After examining a few objections, the paper concludes by contextualizing this argument in relation to Part II of Hume’s essay and in relation to broader apologetic concerns. In short, it is vital to recognize that this paper’s focus is Hume’s first account of ‘miracle,’ rather than his argument against miracle-testimony more broadly, but the argument could be coupled with other arguments against Hume’s broader attack on miracle-testimony.

What does it mean to trust the results of a computer simulation? This paper argues that trust in simulations should be grounded in empirical evidence, good engineering practice, and established theoretical principles. Without these constraints, computer simulation risks becoming little more than speculation. We argue against two prominent positions in the epistemology of computer simulation and defend a conservative view that emphasizes the difference between the norms governing scientific investigation and those governing ordinary epistemic practices.

According to The Consensus Gentium Argument from the premise: “Everyone believes that God exists” one can conclude that God does exist. In my paper I analyze two ways of defending the claim that somebody’s belief in God is a prima facie reason to believe. Kelly takes the fact of the commonness of the belief in God as a datum to explain and argues that the best explanation has to indicate the truthfulness of the theistic belief. Trinkaus Zagzebski grounds her defence (...) on rationality of epistemic trust in others. In the paper I argue that the second line of reasoning is more promising and I propose its improved version.

In everyday life and in science we acquire evidence of evidence and based on this new evidence we often change our epistemic states. An assumption underlying such practice is that the following EEE Slogan is correct: 'evidence of evidence is evidence' (Feldman 2007, p. 208). We suggest that evidence of evidence is best understood as higher-order evidence about the epistemic state of agents. In order to model evidence of evidence we introduce a new powerful framework for modelling epistemic states, Dyadic (...) Bayesianism. Based on this framework, we then discuss characterizations of evidence of evidence and argue for one of them. Finally, we show that whether the EEE Slogan holds, depends on the specific kind of evidence of evidence. (shrink)

"Rationality: Contexts and Constraints" is an interdisciplinary reappraisal of the nature of rationality. In method, it is pluralistic, drawing upon the analytic approaches of philosophy, linguistics, neuroscience, and more. These methods guide exploration of the intersection between traditional scholarship and cutting-edge philosophical or scientific research.

We consider the complex interactions between rape culture and epistemology. A central case study is the consideration of a deferential attitude about the epistemology of sexual assault testimony. According to the deferential attitude, individuals and institutions should decline to act on allegations of sexual assault unless and until they are proven in a formal setting, i.e., a criminal court. We attack this deference from several angles, including the pervasiveness of rape culture in the criminal justice system, the epistemology of testimony (...) and norms connecting knowledge and action, the harms of tacit idealizations away from important contextual factors, and a contextualist semantics for 'knows' ascriptions.

What does it mean to know how to do something? This book develops a comprehensive account of know-how, a crucial epistemic goal for all who care about getting things right, not only with respect to the facts, but also with respect to practice. It proposes a novel interpretation of the seminal work of Gilbert Ryle, according to which know-how is a competence, a complex ability to do well in an activity in virtue of guidance by an understanding of what it (...) takes to do so. This idea is developed into a full-fledged account, Rylean responsibilism, which understands know-how in terms of the normative guidance and responsible control of one's acts. Within the complex current debate about know-how, this view occupies a middle ground position between the intellectualist claim that know-how just is propositional or objectual knowledge and the anti-intellectualist claim that know-how just is ability. In genuine know-how, practical ability and guiding intellect are both necessary, but essentially intertwined. (shrink)

In this paper I will introduce a practical explication for the notion of expertise. At first, I motivate this attempt by taking a look on recent debates which display great disagreement about whether and how to define expertise in the first place. After that I will introduce the methodology of practical explications in the spirit of Edward Craig’s Knowledge and the state of nature along with some conditions of adequacy taken from ordinary and scientific language. This eventually culminates in the (...) respective explication of expertise according to which this term essentially refers to a certain kind of service-relation. This is why expertise should be considered as a predominantly social kind. This article will end up with a discussion of advantages and prima facie plausible objections against my account of expertise. (shrink)

I can, given the right conditions, transmit my knowledge to you by telling you some information. If I know the time, and if all goes well, I can bring it about that you know it too. If conditions are right, all I have to do is assert to you what time it is. Paradigmatically, speakers use assertions to transmit what they know to their hearers. Clearly, assertion and testimony are tightly connected. The nature of this connection, however, is not so (...) clear. According to many accounts, assertion has an epistemic constitutive norm. This norm appears to be able to account for some important features of testimony: first, testimonial knowledge transmission, second, the reliability of testimony, and third, the epistemic rights exchanged in cases of testimony. In this paper, however, I argue against this apparent ability. The constitutive norm of assertion, I argue, plays no role in accounts of testimonial knowledge transmission, or of the epistemic rights that testimony confers. This is especially clear whe..

This paper critically examines currently influential transparency accounts of our knowledge of our own beliefs that say that self-ascriptions of belief typically are arrived at by “looking outward” onto the world. For example, one version of the transparency account says that one self-ascribes beliefs via an inference from a premise to the conclusion that one believes that premise. This rule of inference reliably yields accurate self-ascriptions because you cannot infer a conclusion from a premise without believing the premise, and so (...) you cannot infer from a premise that you believe the premise unless you do believe it. I argue that this procedure cannot be a source of justification, however, because one can be justified in inferring from p that q only if p amounts to strong evidence that q is true. This is incompatible with the transparency account because p often is not very strong evidence that you believe that p. For example, unless you are a weather expert, the fact that it will rain is not very strong evidence that you believe it will rain. After showing how this intuitive problem can be made precise, I conclude with a broader lesson about the nature of inferential justification: that beliefs, when justified, must be underwritten by beliefs, when justified, must be underwritten by evidential relationships between the facts or propositions which those beliefs represent.

A natural view of testimony holds that a source's statements provide one with evidence about what the source believes, which in turn provides one with evidence about what is true. But some theorists have gone further and developed a broadly analogous view of memory. According to this view, which this essay calls the “diary model,” one's memory ordinarily serves as a means for one's present self to gain evidence about one's past judgments, and in turn about the truth. This essay (...) rejects the diary model's analogy between memory and testimony from one's former self, arguing first that memory and a diary differ with respect to their psychological roles, and second that this psychological difference underwrites important downstream epistemic differences. The resulting view stands opposed to prominent discussions of memory and testimony, which either, like the diary model, treat memory by analogy to what we naively wish to say about testimony, or which instead attempt to extend to testimony the epistemically preservative role of memory.

I consider some uses of citations in academic writing and analyze them as instances of the “appeal to expert opinion” argumentative scheme to show that the critical questions commonly linked to this scheme are difficult to apply. I argue that, by considering citations as special communicative and argumentative situated acts, their use in real practice can be explained more adequately. Adaptation to the audience and to the social constraints is common and necessary in order to collaborate with others and to (...) advance in a discipline, but also to attain rhetorical goals that differ from strictly cognitive ones.

Two key intuitions regarding knowledge are explored: that knowledge is a kind of cognitive achievement and that knowledge excludes luck. It is claimed that a proper understanding of how these intuitions should inform our conception of knowledge leads to some surprising results, not just as regards the theory of knowledge more generally but also as regards the epistemology of testimonial knowledge. In particular, it is argued that this conception of knowledge motivates a new kind of proposal B quasi-reductionism B that (...) can accommodate the motivations behind both reductionist and anti-reductionist accounts of the epistemology of testimonial knowledge.

This paper argues that the problem of expertise calls for a rapprochement between social epistemology and argumentation theory. Social epistemology has tended to emphasise the role of expert testimony, neglecting the argumentative function of appeals to expert opinion by non-experts. The first half of the paper discusses parallels and contrasts between the two cases of direct expert testimony and appeals to expert opinion by our epistemic peers, respectively. Importantly, appeals to expert opinion need to be advertised as such, if they (...) are to sway an epistemic peer. The second half of the paper sketches a theoretical framework for thinking about assessments of expertise in a unified way, via a ‘default and challenge’ model that emphasises the need for a version of conversational scorekeeping. It is through such scorekeeping that interlocutors can track and coordinate their differences in epistemic outlook. The paper concludes with a genealogical perspective on the function of (attributions of) expertise: acceptance of another’s appeal to expert opinion may be construed as tacit agreement that inquiry, for now, has been taken far enough.

Everyday life reasoning and argumentation is defeasible and uncertain. I present a probability logic framework to rationally reconstruct everyday life reasoning and argumentation. Coherence in the sense of de Finetti is used as the basic rationality norm. I discuss two basic classes of approaches to construct measures of argument strength. The first class imposes a probabilistic relation between the premises and the conclusion. The second class imposes a deductive relation. I argue for the second class, as the first class is (...) problematic if the arguments involve conditionals. I present a measure of argument strength that allows for dealing explicitly with uncertain conditionals in the premise set. (shrink)

Subject-sensitive invariantism (SSI), the view that whether a subject knows depends on the practical stakes, has been charged with ‘knowledge laundering’: together with widely held knowledge-transmission principles, SSI appears to allow improper knowledge acquisition. I argue that this objection fails because it depends on faulty versions of transmission principles that would raise problems for any view. When transmission principles are properly understood, they are shown to be compatible with SSI because they do not give rise to improper knowledge acquisition. The (...) upshot is a better understanding of the nature and structure of these transmission principles. (shrink)

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

Should one trust experts? My answer to this question is a qualified ‘no’. In this paper I explore the conditions under which it is rational to trust and defer to experts, and those under which it may be rational to refrain from doing so. I draw on two important factors for an actor’s trust in a partner: trust depends on the partner’s competence and on the partner’s interests. I propose that the conditions under which it is rational to trust and (...) defer to experts depend on the competences of the layperson and the expert, and the degree of interest alignment. I present a model that demonstrates that it can be practically infeasible and even logically impossible to determine the expert’s level of competence and the degree of interest alignment. Although it may sound pessimistic that one can rationally refrain from trusting experts, I will also explore some more optimistic conclusions. (shrink)

Conservatism’s core claim is that traditions play an important, if not essential, role in the acquisition of normative knowledge. However, that thesis has never been adequately defended. Three things are missing from conservative political thought: a traditionalist account of propositional normative knowledge, an explicit and sustained positive argument for traditions’ role in the acquisition of normative knowledge, and deference to relevant work in other areas of philosophy, especially epistemology. In this thesis, I provide an argument for conservatism which remedies each (...) of these defects. I call it the Social Knowledge Argument. According to the Social Knowledge Argument, some beliefs formed out of deference to the traditions of one’s society constitute normative knowledge, since deference to the traditions of one’s society is a reliable process for normative belief formation in some societies. Deference to the traditions of one’s society is reliable in some societies because traditions are the outputs of cultural evolution and the latter tends to produce traditions that capture the demands of normative domains such as morality. The Social Knowledge Argument constitutes a traditionalist account of propositional normative knowledge, is an explicit argument for traditions’ epistemic role, and utilises intellectual resources unavailable to previous generations of conservative writers. Specifically, the Social Knowledge Argument assumes a process reliabilist theory of knowledge, and these are of recent provenance, and while conservatives have always appealed to cultural evolution, I am able to draw on fully-fledged scientific accounts of cultural evolution which were unavailable to or neglected by previous conservative writers.
