How much linguistic understanding is required for testimonial knowledge acquisition? One answer is that, so long as we grasp the content expressed by the speaker, it does not matter if our understanding of it is poor. Call this the ‘Liberal View’ of testimony. This approach looks especially promising when combined with the thesis that we share a public language that makes it easy to grasp the right content. In this paper, I argue that this picture is epistemically problematic. Poor linguistic (...) understanding undermines our ability to recognise evidence and counterevidence for the testimonial content. Because of this, in many cases in which a hearer’s understanding is poor, her resultant testimonial belief will lack sufficient warrant to qualify as knowledge. Given that we often do not possess a sufficiently good understanding of the testimony we consume, I argue that we acquire far less knowledge through testimony than the Liberal View suggests.

It is a commonplace in philosophy of action that there is and must be teleologically basic action: something done on an occasion without doing it by means of doing anything else. It is widely believed that basic actions are exercises of skill. As the source of the need for basic action is the structure of practical reasoning, this yields a conception of skill and practical reasoning as complementary but mutually exclusive. On this view, practical reasoning and complex intentional action depend (...) on skill and basic action, but the latter pair are not themselves rationally structured: the movements a basic action comprises are not intentional actions, and they are not structured as means to an end. However, Michael Thompson and Douglas Lavin have argued that action that bears no inner rational structure is not intentional action at all, and that therefore there can be no such thing as basic action. In this paper, I argue that their critique shows that standard conceptions of basic action are indeed untenable, but not that we can do without an alternative. I develop an alternative conception of skill and basic action on which their basicness is not to be equated with simplicity: like deliberation and non-basic action, they are teleologically complex, but their complexity takes a different form. On this view, skill contrasts with deliberation—not because it is not a manifestation of practical reason, but because the two are specifically different manifestations of practical reason. (shrink)

Under which conditions are we epistemically justied to believe that what other people tell us is true? Traditionally, the answer has either been reductionist or anti-reductionist: Either our justication reduces to non-testimonial reasons, or we have a presumptive, though defeasible, right to believe what we are told. However, different cases pull in different directions. Intuitively, someone asking for the time is subject to different epistemic standards than a surgeon consulting a colleague before a dangerous operation. Following this line of thought, (...) this paper develops an account of testimonial justication that captures our reductionist as well as our anti-reductionist intuitions. It is argued that the speaker’s commitment to an epistemic norm, as well as the hearer’s understanding of that norm, gives the hearer a presumptive right to believe what she is told. However, this justication doesn’t apply to situations with high practical risks. Here, the hearer needs reductive reasons to believe that her interlocutor is especially qualied to give her the desired information. (shrink)

Recent work on testimony has raised questions about the extent to which testimony is a distinctively second-personal phenomenon and the possible epistemic significance of its second-personal aspects. However, testimony, in the sense primarily investigated in recent epistemology, is far from the only way in which we acquire knowledge from others. My goal is to distinguish knowledge acquired from testimony (learning from being told) from knowledge acquired from teaching (learning from being taught), and to investigate the similarities and differences between the (...) two with respect to the interpersonal dimensions of their structures.

Is there good reason to worry about celebrity involvement in democratic politics? The rise of celebrity politicians such as Donald Trump and Vladimir Zelensky has led political theorists and commentators to worry that the role of expertise in democratic politics has been undermined. According to one recent critique, celebrities possess a significant degree of epistemic power that is unconnected to appropriate expertise. This presents a problem both for deliberative and epistemic theories of democratic legitimacy, which ignore this form of power, (...) and for real existing democracies attempting to meet the standards of legitimacy set out by these theories. But do these critiques apply to democratic elitism? In this paper, we argue that recognition of celebrity epistemic power in fact represents a valuable resource for supporting the legitimacy and practice of democratic elitism, though these benefits do come with certain risks to which elite theories are particularly vulnerable.

Under what conditions are we justified in believing what people tell us? Traditionally, the answer has either been reductionist or anti-reductionist. Either our justification reduces to non-testimonial reasons, or we have a presumptive, though defeasible, right to believe what we are told. However, some philosophers have argued that we need to look beyond this dichotomy. Following this line of thought, this paper examines and criticizes a recent proposal by John Greco. According to Greco, testimony has two functions: (1) passing on (...) information within an epistemic community; (2) receiving information from an outside source. (1) calls for anti-reductionism, while (2) requires reductive reasons. In response to Greco, several cases are presented, showing that his position leads to counterintuitive consequences. In the light of this result, an alternative, risk-dependent, account is put forward. It is argued that the practical risks connected to receiving false information determine which epistemic treatment is appropriate. (shrink)

Epistemology is sometimes said to be a normative discipline, but what this characterization means is often left unclear. This paper distinguishes two kinds of normativity and thereby provides a new way of understanding attributions of normativity. Associated with this distinction are two kinds of epistemological reflection. These are shown to be parallel to two kinds of ethical reflection. In the light of what emerges in showing these points, the paper clarifies the requirements for naturalizing epistemology, the place normativity might have, (...) given certain kinds of naturalization, and the sense in which knowledge and justification may be viewed as normative.

The paper makes two points. First, any theory of knowledge must explain the difference between cases of knowledge from falsehood and Gettier cases where the subject relies on reasoning from falsehood. Second, the closeness-to-the-truth approach to explaining the difference between knowledge-yielding and knowledge-suppressing falsehoods does not hold up to scrutiny.

The case of very young children is a test case for the plausibility of reductionism about testimonial warrant. Reductionism requires reductive reasons, reductively justified and actively deployed for testimonial justification. Though nascent language-users enjoy warranted testimony based beliefs, they do not meet these three reductionist demands. This paper clearly formulates reductionism and the infant/child objection. Two rejoinders are discussed: an influential conceptual argument from Jennifer Lackey’s paper “Testimony and the Infant/Child Objection” and the growing empirical evidence from developmental psychology on (...) selective trust in children. Neither Lackey’s argument nor the empirical evidence vindicate reductionism. (shrink)

In this paper I consider whether the reasons on which our testimonial beliefs are directly based—“testimonial reasons”—are basic reasons for belief. After laying out a Dretske-inspired psychologistic conception of reasons for belief in general and a corresponding conception of basic reasons for belief, I present a prima facie case against the basicality of testimonial reasons. I then respond to a challenge from Audi to this case. To the extent that my response is successful, the viability of an important kind of (...) inferentialism about testimonial belief is preserved.

There is a clean image of knowledge transmission between thinkers that involves sincere and reliable speakers, and hearers who carefully assess the epistemic credentials of the testimony that they hear. There is, however, a murkier side to testimonial exchange where deception and lies hold sway. Such mendacity leads to sceptical worries and to discussion of epistemic vice. Here, though, I explore cases where deceit and lies are involved in knowledge transmission. This may sound surprising or even incoherent since lying usually (...) involves saying something that is false. Even if a liar unwittingly tells the truth, those believing their testimony would not acquire knowledge. In §1, however, I suggest a range of examples where lies can be used to transmit knowledge. The kinds of cases upon which I focus are those involving ‘engineered knowledge’, where a speaker skilfully manipulates another into having a true belief. Such cases are epistemologically significant for several reasons. First, they are counter-examples to a range of widely held assumptions about knowledge. We have, for example, cases where sincerity is not necessary for knowledge transmission, where there is knowledge from falsehood, and, as we shall discuss in §2, knowledge that is fragile or not safe. Second, in §3 and §4 I suggest that engineered knowledge is best captured by a virtue theoretic approach to testimonial transmission. (shrink)

Muito do que conhecemos deriva do relato de outras pessoas. Nem todo relato, entretanto, é apto para produzir crenças justificadas. O que se pretende neste paper é analisar as condições que devem ser satisfeitas para que um testemunho possa produzir crenças justificadas e, a partir daí, conhecimento. Assumindo uma posição não reducionista do testemunho, segue-se a contribuição de Robert Audi para concluir que o testemunho é fonte legítima de justificação e de conhecimento, argumentando que a confiança que se tem nos (...) outros pode, em circunstâncias adequadas, satisfazer as condições para a justificação e para o conhecimento.
