Hearsay or indirect testimony receives little discussion even today in epistemology, and yet it represents one of the cardinal modes for the transmission of knowledge and for human cognitive development. It suffices to think of school education whereby a student listens to teachers reporting knowledge acquired, often indirectly, from the most varied sources such as text books, newspapers, personal memory, television, etc… Or let us consider the importance of oral tradition in the social and cultural development of civilisations. Or even (...) let us call to mind the learning process of infants who, only thanks to the knowledge learned from others, succeed in learning the language. Finally, with the emerging digital technology, the information gleaned from third parties is influencing the creation of knowledge in a full gamut of fields, in a quasi-comprehensive manner. This leads us to claim that hearsay, despite the reductionist conceptual scheme to which epistemology has confined it in that indirect testimony, is in any case quintessential in the dissemination of knowledge. This work fully expounds upon the basic mechanism of indirect testimonial transmission and provides an epistemologically founded explanation of the cognitive possibilities of hearsay by investigating, in the light of the anti-reductionist paradigm, three mutually connected epistemic properties, namely trust, reputation and coherence, that are key in the epistemic justification of the truth acquired via an indirect testimony.

Mainstream epistemologists have recently made a few isolated attempts to demonstrate the particular ways, in which specific types of knowledge are partly social. Two promising cases in point are Lackey’s dualism in the epistemology of testimony and Goldberg’s process reliabilist treatment of testimonial and coverage-support justification. What seems to be missing from the literature, however, is a general approach to knowledge that could reveal the partly social nature of the latter anytime this may be the case. Indicatively, even though Lackey (...) :345–361, 2007) has recently launched an attack against the Credit Account of Knowledge on the basis of testimony, she has not classified her view of testimonial knowledge into any of the alternative, general approaches to knowledge. Similarly, even if Goldberg’s attempt to provide a process reliabilist explanation of the social nature of testimonial knowledge is deemed satisfactory, his attempt to do the same in the case of coverage-support justification does not deliver the requisite result. This paper demonstrates that CAK can in fact provide, pace Lackey’s renunciation of the view, a promising account of the social nature of both testimonial and coverage-supported knowledge. Additionally, however, it can display further explanatory power by also revealing the social nature of knowledge produced on the basis of epistemic artifacts. Despite their disparities, all these types of knowledge count as partly social in nature, because in all these cases, according to CAK, the epistemic credit for the individual agent’s true belief must spread between the individual agent and certain parts of her epistemic community. Accordingly, CAK is a promising candidate for providing a unified approach to several and, perhaps all possible, instances of what we may call ‘weak epistemic anti-individualism’ within mainstream epistemology: i.e., the claim that the nature of knowledge can occasionally be both social and individual at the same time.

An influential view in the epistemology of testimony is that typical or paradigmatic beliefs formed through testimonial uptake are noninferential. Some epistemologists in particular defend a causal version of this view: that beliefs formed from testimony (BFT) are generated by noninferential processes. This view is implausible, however. It tends to be elaborated in terms that do not really bear it out – e.g. that BFT is fixed directly, immediately, unconsciously or automatically. Nor is causal noninferentialism regarding BFT plausibly expressed in (...) terms of belief-independent belief formation; the complex cognitive details of BFT fixation do not accord well with such a view. But perhaps the most significant issue is that the relevant causal notion of inference itself is not particularly well-defined, at least with respect to BFT. Causal noninferentialism in this domain is obscure as a result, but this does not in turn clearly vindicate any interesting version of inferentialism. (shrink)

One thing wrong with lying is that it can be manipulative. Understanding why lying can be a form of manipulation involves understanding how our telling someone something can give them a reason to believe it, and understanding this requires seeing both how our telling things can invite trust and how trust can be a reason to believe someone. This paper aims to outline the mechanism by means of which lies can be manipulative and through doing so identify a unique reason (...) for accepting testimony; a reason based on trusting a speaker’s telling.

Testimony is a vital and ubiquitous source of knowledge. Were we to refrain from accepting the testimony of others, our lives would be impoverished in startling and debilitating ways. Despite the vital role that testimony occupies in our epistemic lives, traditional epistemological theories have focused primarily on other sources, such as sense perception, memory, and reason, with relatively little attention devoted specifically to testimony. In recent years, however, the epistemic significance of testimony has been more fully appreciated. I shall here (...) focus on two questions that have received the most attention in recent work in the epistemology of testimony. First, is testimonial knowledge acquired only by being transmitted from speaker to hearer? Second, must a hearer have positive reasons to justifiedly accept a speaker's testimony? (shrink)

Within the contemporary epistemology of testimony, it is widely assumed that testimonial scepticism can be dismissed without engaging with possible reasons or arguments supporting the view. This assumption of dismissibility both underlies the debate between reductionist and non-reductionist views of testimony and is responsible for the neglect of testimonial scepticism within contemporary epistemology. This paper argues that even given liberal assumptions about what may constitute valid grounds for the dismissal of a sceptical view, the assumption that testimonial scepticism is dismissible (...) should be rejected. For even if familiar sceptical positions and scepticism about testimonial justification can be dismissed on such grounds, scepticism about testimonial knowledge cannot. (shrink)

A contemporary debate concerning the epistemology of testimony is portrayed by its protagonists as having its origins in the eighteenth century and the respective views of David Hume and Thomas Reid. Hume is characterized as a reductionist and Reid as an anti-reductionist. This terminology has been widely adopted and the reductive approach has become synonymous with Hume. In Sect. 1 I spell out the reductionist interpretation of Hume in which the justification possessed by testimonially-acquired beliefs is reducible to the epistemic (...) properties of perception, memory and inductive inference. This account of testimony is taken to be found in the section ‘On Miracles’ of Hume’s Enquiry concerning Human Understanding. In Sect. 2 I introduce the distinction between global and local reductionism, and Coady’s interpretation of Hume as a global reductionist. He takes Hume’s position to be untenable. The rest of the paper explores alternative interpretations of Hume. Section 3 develops a local reductionist interpretation of Hume on testimony. It is argued, though, that such an approach is unstable and, in response, Sect. 4 turns to anti-reductionism in its contemporary forms and in Reid’s teleological account. In Sect. 5 I argue for an anti-reductionist account of Hume, one drawn from his discussion of the testimony of history in the Treatise of Human Nature, thus moving away from the usually exclusive focus upon the discussion of miracles in the first Enquiry, upon which the reductionist interpretation is based. Given the standard meaning of ‘Humeanism’ in the current debate, my interpretation amounts to the claim that Hume is not a Humean with respect to testimony. (shrink)

A view of knowledge—what I call the "Deserving Credit View of Knowledge" —found in much of the recent epistemological literature, particularly among so-called virtue epistemologists, centres around the thesis that knowledge is something for which a subject deserves credit. Indeed, this is said to be the central difference between those true beliefs that qualify as knowledge and those that are true merely by luck—the former, unlike the latter, are achievements of the subject and are thereby creditable to her. Moreover, it (...) is often further noted that deserving credit is what explains the additional value that knowledge has over merely lucky true belief. In this paper, I argue that the general conception of knowledge found in the DCVK is fundamentally incorrect. In particular, I show that deserving credit cannot be what distinguishes knowledge from merely lucky true belief since knowledge is not something for which a subject always deserves credit. (shrink)

An objection to reductionism in the epistemology of testimony that is often repeated but rarely defended in detail is that there is not enough positive evidence to provide the non-testimonial, positive reasons reductionism requires. Thus, on pain of testimonial skepticism, reductionism must be rejected. Call this argument the ‘Not Enough Evidence Objection’. I will defend reductionism about testimonial evidence against the NEEO by arguing that we typically have non-testimonial positive reasons in the form of evidence about our testifier's evidence. With (...) a higher-level evidence principle borrowed from recent work on the epistemology of disagreement, I argue that, granting some plausible assumptions about conversational norms, the NEEO is unsound.Send article to KindleTo send this article to your Kindle, first ensure [email protected] is added to your Approved Personal Document E-mail List under your Personal Document Settings on the Manage Your Content and Devices page of your Amazon account.

We very often grant that a person can gain knowledge on the basis of epistemic artifacts such as telescopes, microscopes and so on. However, this intuition threatens to undermine virtue reliabilism according to which one knows that p if and only if one’s believing the truth that p is the product of a reliable cognitive belief-forming process; in an obvious sense epistemic artifacts are not parts of one’s overall cognitive system. This is so, unless the extended cognition hypothesis (HEC) is (...) true. According to HEC when parts of the environment become properly coupled to the agent’s brain then they too can be considered constitutive parts of the overall cognitive mechanism—i.e. cognition potentially extends to the world surrounding the agent. Interestingly, HEC and the broader framework of virtue reliabilism share some intriguing similarities, which render these two views mutually supportive. Making these similarities explicit provides a principled account of the way in which our knowledge-conducive cognitive characters may extend beyond our natural cognitive capacities by incorporating epistemic artifacts.

Dualism in the Epistemology of Testimony and the Ability Intuition Content Type Journal Article DOI 10.1007/s11406-010-9291-4 Authors Spyridon Orestis Palermos, Department of Philosophy, School of Philosophy, Psychology and Language Sciences (PPLS), The University of Edinburgh, Edinburgh, UK Journal Philosophia Online ISSN 1574-9274 Print ISSN 0048-3893.

Testimony is an indispensable source of information. Yet, contrary to ‘literalism’, speakers rarely mean just what they say; and even when they do, that itself is something the hearer needs to realize. So, understanding instances of testimony requires more than merely reading others' messages off of the words they utter. Further, a very familiar and theoretically well-entrenched approach to how we arrive at such understanding serves to emphasize, not merely how deeply committed we are to testimony as a reliable source (...) of information, but that epistemological questions about testimonial belief are – perhaps even must be – posterior to such a commitment. This result does not itself dictate any particular views on the epistemology of testimony. However, not only does the failure of literalism not support the view that the justificatory basis of testimony-based beliefs is importantly inferential; it in fact undermines a key premise in one important argument for the view that one needs independent, positive reasons for accepting a given testimonial report. More generally, the present paper illustrates how discussions of the epistemology of testimony might usefully interact with an examination of the epistemology of understanding. (shrink)

Philosophers agree that an important part of our knowledge is acquired via testimony. One of the main objectives of social epistemology is therefore to specify the conditions under which a hearer is justified in accepting a proposition stated by a source. Non-reductionists, who think that testimony could be considered as an a priori source of knowledge, as well as reductionists, who think that another type of justification has to be added to testimony, share a common conception about children development. Non-reductionists (...) believe that infants and children are fundamentally gullible and their gullibility could be seen as an example for justifying testimony, while reductionists believe that this gullibility is merely an exception that should be taken into account. The objective of this paper is to review contemporary literature in developmental psychology providing empirical grounds likely to clarify this philosophical debate. What emerges from current research is a more elaborated vision of children’s attitude toward testimony. Even at a very young age, children do not blindly swallow information coming from testimony; doubtful or contradictory information is automatically screened by their cognitive system. Even if they are unable to give positive reasons for the acceptance of a given testimony, young children are not gullible. Such empirical findings tend to call into question the radical opposition between reductionism and non-reductionism. (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.

Many epistemologists agree that even very young children sometimes acquire knowledge through testimony. In this paper I address two challenges facing this view. The first (building on a point made in Lackey (2005)) is the defeater challenge, which is to square the hypothesis that very young children acquire testimonial knowledge with the fact that children (whose cognitive immaturity prevents them from having or appreciating reasons) cannot be said to satisfy the No‐Defeaters condition on knowledge. The second is the extension challenge, (...) which is to give a motivated, extensionally‐adequate account of the conditions on testimonial knowledge in early childhood. Neither challenge can be met merely by endorsing externalism about knowledge; but we can meet both by reconceiving the process that eventuates in the child’s consumption of testimony. My central thesis is that this process should be seen as implicating features of the child’s social environment. The result is a novel anti‐individualistic externalism about knowledge. (shrink)

It is common to interpret Kant’s idea of public reason and the Enlightenment motto to ‘think for oneself’ as incompatible with the view that testimony and judgement of credibility is essential to rational public deliberation. Such interpretations have led to criticism of contemporary Kantian approaches to deliberative democracy for being intellectualistic, and for not considering our epistemic dependence on other people adequately. In this article, I argue that such criticism is insufficiently substantiated, and that Kant’s idea of public reason is (...) neither at odds with deference to a certain kind of authority, nor with making judgements of character in rational deliberation. This view is corroborated by recent work on Kant’s epistemology of testimony. (shrink)

Anti-reductionists hold that beliefs based upon comprehension (of both force and content) of tellings are non-inferentially justified. For reductionists, on the other hand, comprehension as such is not in itself a warrant for belief: beliefs based on it are justified only if inferentially supported by other beliefs. I discuss Elizabeth Fricker's argument that even if anti-reductionism is right in principle, its significance is undercut by the presence of background inferential support: for mature knowledgeable adults, justification from comprehension as such plays (...) no active role, and is superseded by inferential warrant. I show that her argument begs important questions. Inferential and non-inferential support combine to over-determine the justification of comprehension-based beliefs. (shrink)

This paper aims to outline, evaluate, and ultimately reject a virtue epistemic theory of testimony before proposing a virtue ethical theory. Trust and trustworthiness, it is proposed, are ethical virtues; and from these ethical virtues, epistemic consequences follow.
