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)

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.

In all three of its manifestations, —abusive, circumstantial and tu quoque—the role of the ad hominem is to raise a doubt about the opposite party’s casemaking bona-fides.Provided that it is both presumptive and provisional, drawing such a conclusion is not a logical mistake, hence not a fallacy on the traditional conception of it. More remarkable is the role of the ad hominem retort in seeking the reassurance of one’s opponent when, on the face of it, reassurance is precisely what he (...) would seem to be ill-placed to give. Brief concluding remarks are given over to an examination of rival approaches to the ad hominem, especially those in which it is conceived of as a dialectical error. (shrink)

Science communication via testimony requires a certain level of trust. But in the context of ideologically-entangled scientific issues, trust is in short supply—particularly when the issues are politically ‘entangled’. In such cases, cultural values are better predictors than scientific literacy for whether agents trust the publicly-directed claims of the scientific community. In this paper, we argue that a common way of thinking about scientific literacy—as knowledge of particular scientific facts or concepts—ought to give way to a second-order understanding of science (...) as a process as a more important notion for the public’s trust of science.

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

Is it harder to acquire knowledge about things that really matter to us than it is to acquire knowledge about things we don't much care about? Jason Stanley 2005 argues that whether or not the relational predicate 'knows that' holds between an agent and a proposition can depend on the practical interests of the agent: the more it matters to a person whether p is the case, the more justification is required before she counts as knowing that p. The evidence (...) for Stanley's thesis includes a number of intuitive judgments about examples. In this paper we provide parallel examples for which Stanley's thesis requires unwelcome knowledge-attributions, and argue that this is possible because his thesis conflicts with familiar and plausible principles about knowledge.

The acquaintance debate in aesthetics has been traditionally divided between pessimists, who argue that testimony does not provide others with aesthetic knowledge of artworks, and optimists, who hold that acquaintance with an artwork is not a necessary precondition for acquiring aesthetic knowledge. In this paper I propose a reconciliationist solution to the acquaintance debate: while aesthetic knowledge can be had via testimony, aesthetic judgment requires acquaintance with the artwork. I develop this solution by situating it within a virtue aesthetics framework (...) based on Ernest Sosa's virtue epistemology. I go on to apply the solution to the debates on moral testimony and expert testimony. An interesting variant on Gettier cases emerges: cases in which subjects have knowledge, but it has been formed by the wrong competence. (shrink)

Let us focus on what I take it is the paradigm case of testimony—the intentional transfer of a belief from one agent to another, whether in the usual way via a verbal assertion made by the one agent to the other, or by some other means, such as through a note.1 So, for example, John says to Mary that the house is on fire (or, if you like, ‘texts’ her this message on her phone), and Mary, upon hearing this, forms (...) the belief that the house is on fire and consequently exits the building at speed. Clearly, a great deal of our beliefs are gained via testimony, and if the epistemic status of our testimonybased beliefs were to be called into question en masse, then this would present us with quite a predicament. It is thus essential that we have some plausible account of the epistemology of testimony. Our primary focus will be on the justification for our testimony-based beliefs, though along the way we will say a little about other relevant epistemic notions like epistemic entitlement as well.

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

At first glance there seem to be many similarities between Thomas S. Kuhn’s and Ludwik Fleck’s accounts of the development of scientific knowledge. Notably, both pay attention to the role played by the scientific community in the development of scientific knowledge. But putting first impressions aside, one can criticise some philosophers for being too hasty in their attempt to find supposed similarities in the works of the two men. Having acknowledged that Fleck anticipated some of Kuhn’s later theses, there seems (...) to be a temptation in more recent research to equate both theories in important respects. Because of this approach, one has to deal with the problem of comparing the most notable technical terms of both philosophers, namely ‘‘thought style’’ and ‘‘paradigm’’. This paper aims at a more thorough comparison between Ludwik Fleck’s concept of thought style and Thomas Kuhn’s concept of paradigm. Although some philosophers suggest that these two concepts are essentially equal in content, a closer examination reveals that this is not the case. This thesis of inequality will be defended in detail, also taking into account some of the alleged similarities which may be responsible for losing sight of the differences between these theories.

Why do we trust TV news? What reasons might support a recipient’s assessment of the trustworthiness of this kind of information? This paper presents a veritistic analysis of the epistemic practice of news production and communication. The topic is approached by discussing a detailed case study, namely the characteristics of the most popular German news programme, called the ‘Tagesschau’. It will be shown that a veritistic analysis can indeed provide a recipient with relevant reasons to consider when pondering on the (...) trustworthiness of sources of information. Moreover, it will turn out that these reasons are part of what recipients might gather from media literacy. (shrink)

Hume's essay on the credibility of miracle reports has always been controversial, with much debate over how it should be interpreted, let alone assessed. My aim here is to summarise what I take to be the most plausible views on these issues, both interpretative and philosophical, with references to facilitate deeper investigation if desired. The paper is divided into small sections, each headed by a question that provides a focus. Broadly speaking, §§1–3 and §20 are on Hume's general philosophical framework (...) within which the essay is situated, §§4–11 and §19 are on Part 1, §12–18 are on Part 2, and the final three sections §§18–20 sum up my assessment of his arguments.

Philosophers have claimed that education aims at fostering disparate epistemic goals. In this paper we focus on an important segment of this debate involving conversation between Alvin Goldman and Harvey Siegel. Goldman claims that education is essentially aimed at producing true beliefs. Siegel contends that education is essentially aimed at fostering both true beliefs and, independently, critical thinking and rational belief. Although we find Siegel’s position intuitively more plausible than Goldman’s, we also find Siegel’s defence of it wanting. We suggest (...) novel argumentative strategies that draw on Siegel’s own arguments but look to us more promising. (shrink)

Do we insult, offend or slight a speaker when we refuse her testimony? Do we compliment, commend or extol a speaker when we accept her testimony? I argue that the answer to both of these questions is “yes”, but only in some instances, since these respective insults and compliments track the reasons a hearer has for rejecting or accepting testimony. When disbelieving a speaker, a hearer may insult her because she judges the speaker to be either incompetent as a knower (...) or insincere as a teller. However, there are many instances where we reject testimony without making this negative evaluation of the speaker, and as such, without paying her an insult. Testimonial compliments are fewer in number, and are not constitutive of “everyday” testimonial exchanges, since, speakers who are competent as knowers and sincere as tellers are merely behaving correctly in accordance with the norms of testifying. Nevertheless, deferring to an authority on belief can be complimentary to that speaker if by doing so we judge her to have some mastery in a particular domain. Testimonial insults and compliments have important moral implications, particularly with regard to epistemic injustice and therapeutic trust. (shrink)

Este artículo propone una lectura ética de La memoria, la historia, el olvido . Se recurre al testimonio del Holocausto, en tanto acontecimiento injustificable, como instancia de reflexión ética originada en la historia. En estos términos, la respuesta de Ricoeur al Debate de los Historiadores adquiere una importancia capital. Nuestra hipótesis es que esta respuesta es el producto de una larga reflexión sobre las consideraciones de Jean Nabert con respecto a la relación entre la dimensión fáctica y la ética.

This paper considers how we decide whether to believe what we are told. Inference to the Best Explanation, a popular general account of non-demonstrative reasoning, is applied to this task. The core idea of this application is that we believe what we are told when the truth of what we are told would figure in the best explanation of the fact that we were told it. We believe the fact uttered when it is part of the best explanation of the (...) fact of utterance. Having provided some articulation of this account of testimonial inference, the paper goes on to consider whether the account is informative and whether it is plausible. (shrink)

Pessimists think that there is something wrong with relying on deference for one’s moral beliefs—at least if one is morally mature. Call this no deference. They also tend to think that what explains our aversion to cases of moral deference is the fact that they involve deference about moral claims. Call this moral explanation. Recently, both no deference and moral explanation have come under attack. Against no deference, some philosophers offer purported counterexamples involving moral advice. I argue that proponents of (...) this objection face a trilemma depending on how they spell out the details of their counterexamples. Against moral explanation, some philosophers offer debunking explanations of our aversion to moral deference. They present cases of non-moral deference that are troubling and argue that the feature that explains our aversion to this non-moral deference also explains our aversion to moral deference. I argue that none of these explanations (nor their conjunction) can explain all troubling cases of moral deference and that they face objections of their own. I conclude that we should be optimistic about the prospects of moral deference pessimism. (shrink)

There has been much interest in group judgment and the so-called 'wisdom of crowds'. In many real world contexts, members of groups not only share a dependence on external sources of information, but they also communicate with one another, thus introducing correlations among their responses that can diminish collective accuracy. This has long been known, but it has-to date-not been examined to what extent different kinds of communication networks may give rise to systematically different effects on accuracy. We argue that (...) equations that relate group accuracy, individual accuracy, and group diversity are useful theoretical tools for understanding group performance in the context of research on group structure. In particular, these equations may serve to identify the kind of group structures that improve individual accuracy without thereby excessively diminishing diversity so that the net positive effect is an improvement even on the level of collective accuracy. Two experiments are reported where two structures are investigated from this perspective. It is demonstrated that the more constrained network outperforms the network with a free flow of information.

We often prefer non-deferential belief to deferential belief. In the last twenty years, epistemology has seen a surge of sympathetic interest in testimony as a source of knowledge. We are urged to abandon ‘epistemic individualism’ and the ideal of the ‘autonomous knower’ in favour of ‘social epistemology’. In this connection, you might think that a preference for non-deferential belief is a manifestation of vicious individualism, egotism, or egoism. I shall call this the selfishness challenge to preferring non-deferential belief. The aim (...) of this paper is to meet the selfishness challenge by arguing that non-deferential belief is socially valuable. (shrink)

Part One of the paper argues against evidentialism and individualism in religiousepistemology, and in favor of a “social turn” in the field. The idea here is that humanbelief in general, and religious belief in particular, is largely characterized by epistemicdependence on other persons. An adequate epistemology, it is agued, ought to recognizeand account for social epistemic dependence.Part Two considers a problem that becomes salient when we make such a turn. Inshort, how are we to understand the transmission of knowledge and (...) rational faith in areligious tradition? The problem arises because, by all accounts, even the best traditionstransmit superstitions, self-serving prejudices, and other things that are down right falseon any reasonable view. So how is it that these same traditions can also transmit rationalfaith and even knowledge by means of the very same channels, for example channels ofreligious authority and religious teaching?Part Three offers a tentative solution to this problem.

In his work on the epistemology of testimony, Peter Lipton developed an account of testimonial inference that aimed at descriptive adequacy as well as justificatory sophistication. According to ‘testimonial inference to the best explanation’, we accept what a speaker tells us because the truth of her claim figures in the best explanation of the fact that she made it. In this paper, I argue for a modification of this picture. In particular, I argue that IBE plays a dual role in (...) the management and justification of testimony. On the one hand, the coherence and success of our testimony-based projects provides general abductive support for a default stance of testimonial acceptance; on the other hand, we are justified in rejecting specific testimonial claims whenever the best explanation of the instances of testimony we encounter entails, or makes probable, the falsity or unreliability of the testimony in question.Keywords: Testimony; Inference to the best explanation; Abduction; Epistemic justification.

Moral obligation, Darwall argues, is irreducibly second personal. So too, McMyler argues, is the reason for belief supplied by testimony and which supports trust. In this paper, I follow Darwall in arguing that the testimony is not second personal ?all the way down?. However, I go on to argue, this shows that trust is not fully second personal, which in turn shows that moral obligation is equally not second personal ?all the way down?

Here I outline an often under-appreciated position within Anglo-analytic epistemology, that of the apostate to operative metaphilosophical constraints. To help identify and promote awareness of metaphilosophical apostacy, here, I describe the form of metaphilosophical apostacy that I practice in Anglo-analytic epistemology (AAE). My apostasy with respect to AAE begins with significant, metaphilosophical divergences or deep senses of incongruence. A metaphilosophical divergence, on my account, refers to conflict at the level of inquiry-shaping assumptions, constraints, aims, and/or commitments. In this paper, I (...) claim that one way metaphilosophical apostasy emerges in Anglo-analytic epistemology is when inquiry-shaping divergences lead to conceptual indifference. Conceptual indifference, on my account, refers to disinterest that can follow from divergent metaphilosophical and/or aspirational aims and goals for one's favored investigations. To be clear, this is a paper for the growing population of epistemologists who find operative metaphilosophical constraints in AAE ill-fitting. (shrink)

According to an influential Enlightenment ideal, one shouldn't rely epistemically on other people's say-so, at least not if one is in a position to evaluate the relevant evidence for oneself. However, in much recent work in social epistemology, we are urged to dispense with this ideal, which is seen as stemming from a misguided focus on isolated individuals to the exclusion of groups and communities. In this paper, I argue that that an emphasis on the social nature of inquiry should (...) not lead us to entirely abandon the Enlightenment ideal of epistemically autonomous agents. Specifically, I suggest that it is an appropriate ideal for those who serve as experts in a given epistemic community, and develop a notion of expert acceptance to make sense of this. I go on to show that, all other things being equal, this kind of epistemic autonomy among experts makes their joint testimony more reliable, which in turn brings epistemic benefits both to laypeople and to experts in other fields.

Some philosophers deny the existence of composite material objects. Other philosophers hold that whenever there are some things, they compose something. The purpose of this paper is to scrutinize an objection to these revisionary views: the objection that nihilism and universalism are both unacceptably uncharitable because each of them implies that a great deal of what we ordinarily believe is false. Our main business is to show how nihilism and universalism can be defended against the objection. A secondary point is (...) that universalism is harder to defend than nihilism. (shrink)

Much of what we believe we know, we know through the testimony of others. While there has been long-standing evidence that people are sensitive to the characteristics of the sources of testimony, for example in the context of persuasion, researchers have only recently begun to explore the wider implications of source reliability considerations for the nature of our beliefs. Likewise, much remains to be established concerning what factors influence source reliability. In this paper, we examine, both theoretically and empirically, the (...) implications of using message content as a cue to source reliability. We present a set of experiments examining the relationship between source information and message content in people's responses to simple communications. The results show that people spontaneously revise their beliefs in the reliability of the source on the basis of the expectedness of a source's claim and, conversely, adjust message impact by perceived reliability; hence source reliability and message content have a bi-directional relationship. The implications are discussed for a variety of psychological, philosophical and political issues such as belief polarization and dual-route models of persuasion. (shrink)

A bi-level account of trust is developed and defended, one with relevance in ethics as well as epistemology. The proposed account of trust—on which trusting is modelled within a virtue-theoretic framework as a performance-type with an aim—distinguishes between two distinct levels of trust, apt and convictive, that take us beyond previous assessments of its nature, value, and relationship to risk assessment. While Ernest Sosa (2009; 2015; 2017), in particular, has shown how a performance normativity model may be fruitfully applied to (...) belief, my objective is to apply this kind of model in a novel and principled way to trust. I conclude by outlining some of the key advantages of the performance-theoretic bi-level account of trust defended over more traditional univocal proposals. (shrink)

Gilbert (2000) examined the issue of collective intentionality in science. Her paper consisted of a conceptual analysis of the negative role of collective belief, consensus, and joint commitment in science, with a brief discussion of a case study investigated by Thagard (1998a, 1998b). I argue that Gilbert's concepts have to be refined to be empirically more relevant. Specifically, I distinguish between different kinds of joint commitments. I base my analysis on a close examination of Thagard's example, the discovery of Helicobacter (...) pylori, and two other historical cases involving the Copenhagen school of quantum mechanics and the Austrian school of economics. I also argue that it is difficult to fulfill the condition of common knowledge, even in Gilbert's weak sense. I conclude by raising serious doubts about the very possibility of a certain type of joint commitment, which I refer to as an implicit joint commitment. (shrink)

The aim of this article is to present trust as a meta-emotion, such that it is an emotion that precedes first-order emotions. It examines how trust can be considered a meta-emotion by establishing criteria for identifying trust as a meta-emotion. How trust plays out differently in aesthetic and ordinary contexts can provide another mode for investigating meta-emotions. The article illustrates how it is possible to recognize these meta-emotions in narratives. Finally, it presents one of the aims of trust, sharing knowledge (...) between agents, when someone who provides testimony shares knowledge in an epistemic trust process with others. It shows a relationship construction between subjects and objects thanks to the trust, a meta-emotion that represents emotional ties between subjects to achieve another emotion. (shrink)

In Unfit for the Future, Ingmar Persson and Julian Savulescu present a sophisticated argument in defense of the imperative of moral enhancement. They claim that without moral enhancement, the future of humanity is seriously compromised. The possibility of ultimate harm, caused by a dreadful terrorist attack or by a final unpreventable escalation of the present environmental crisis aggravated by the availability of cognitive enhancement, makes moral enhancement a top priority. It may be considered optimistic to think that our present moral (...) capabilities can be successfully improved by means of moral education, moral persuasion, and fear of punishment. So, without moral enhancement, drastic restrictions on human freedom would become the only alternative to prevent those dramatic potential outcomes. In this article, I will try to show that we still have reason to be less pessimistic and that Persson & Savulescu’s arguments are fortunately unconvincing. (shrink)

Epistemic trust is an unacknowledged feature of medical knowledge. Claims of medical knowledge made by physicians, patients, and others require epistemic trust. And yet, it would be foolish to define all epistemic trust as epistemically responsible. Accordingly, I use a routine example in medical practice to illustrate how epistemically responsible trust in medicine is trust in epistemically responsible individuals. I go on to illustrate how certain areas of current medical practice of medicine fall short of adequately distinguishing reliable and unreliable (...) processes because of a failure to systematically evaluate health outcomes. I conclude by articulating the devastating obstacles to the consilience assumption, which takes intellectual character as the standard for epistemic responsibility. (shrink)

In comparison to other epistemic sources (perception, memory and reason) testimony is the only one dealing with the social aspects of gaining and justifying knowledge. One main problem of the current discussion about knowledge by testimony is the concept of testimony itself. It is quite unclear what the correct notion of testimony is supposed to be. In this essay I present a proposal to define the concept of testimony in making a distinction between the conditions which hold in the speaker’s (...) context and the ones necessary and sufficient for the hearer. Furthermore, I will briefly defend the thesis that there is not one general concept of testimony, but that there are different ones connected via a kind of specialisation relation. (shrink)

There have been monumental advances in the study of the social dimensions of knowledge in the late twentieth and early twenty-first centuries. But it has been common within a wide variety of fields--including social philosophy, cognitive science, epistemology, and the philosophy of science--to approach the social dimensions of knowledge as simply another resource to be utilized or controlled. I call this view, in which other people's epistemic significance are only of instrumental value, manipulationism. I identify manipulationism, trace its manifestations in (...) the aforementioned fields, and explain how to move beyond it. The principal strategy that I employ for moving beyond manipulationism consists of synthesizing enactivism and neo-Kuhnian social epistemology. Specifically, I expand the enactivist concept of participatory sense-making by linking it to recent conceptual innovations in social epistemology, such as the concept of immanent cogent argumentation.

Our beliefs utilize various sources: perception, memory, induction, etc. We trust these sources to provide reliable information about the world around us. My dissertation investigates how this trust could be justified. Chapter one introduces background material. I argue that justification rather than knowledge is of primary epistemological importance, discuss the internalism/externalism debate, and introduce an evidentialist thesis that provides a starting point/framework for epistemological theorizing. Chapter two introduces a puzzle concerning justification. Can a belief source provide justification absent prior justification (...) for believing it's reliable? Any answer appears to either make justifying the reliability of a source intellectually unsatisfying or all together impossible. Chapter three considers and rejects a plethora of proposed solutions to our puzzle. Investigating these solutions illustrates the need to further investigate evidence, evidence possession, and evidential support. Chapter four discusses the metaphysics of evidence. I argue that evidence always consists of a set of facts and that fact-proposition pairs stand in confirmation relations isomorphic to those holding between pairs of propositions. Chapter five argues that justification requires what I call actually connected possession of supporting evidence: a subject must be aware of supporting evidence and of the support relation itself. Chapter six argues that the relation constitutive of a set of facts being justificatory evidence is a sui generis and irreducible relation that is knowable a priori. Chapter seven begins by showing how Richard Fumerton's acquaintance theory meets the constraints on a theory of justification laid down in previous chapters. I modify the theory so as to: make room for fallible foundational justification, and allow inferential justification absent higher-order beliefs about evidential connections. Chapter eight applies the developed theory of justification to our initial puzzle. I show how my modified acquaintance theory is in a unique position to vindicate the idea that necessarily a source provides a person with justification only if she is aware of evidence for the reliability of that source. However, this awareness of evidence for a source's reliability falls short of a justified belief and thereby avoids impalement from our dilemma's skeptical horn. (shrink)

How should emotions figure in scientific practice? I begin by distinguishing three broad answers to this question, ranging from pessimistic to optimistic. Confirmation bias and motivated numeracy lead us to cast a jaundiced eye on the role of emotions in scientific inquiry. However, reflection on the essential motivating role of emotions in geniuses makes it less clear that science should be evacuated of emotion. I then draw on Friedrich Nietzsche’s perspectivism to articulate a twenty-first century epistemology of science that recognizes (...) the necessity of emotion to inquiry but aims to manage the biases that emotions can introduce. Twenty-first century perspectivism is both social and (temporally) distal, helping it to overcome a paradox of self-critical inquiry. (shrink)

We sketch and defend a Commitment View of testimony. Unlike alternative approaches, we focus on the ordinary act of testifying, attempting to identify the commitments essential to this speech act and to explain why those commitments are practically necessary. In view of this account, we argue that given the commitments undertaken in testifying, a speaker’s testimony can qualify as evidence.

In this paper, the author presents a theory of testimony intended to provide normative clarity in nonspecialized communication contexts where participants are searching for common ground. Drawn in part from the work of a number of contemporary philosophers, the theory presented is essentially non-reductionist, but contains qualifications and safeguards sufficient to distinguish it from many so-called default acceptance theories of testimony.
