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

This paper argues for an account of insincerity in speech according to which an utterance is insincere if and only if it communicates something that does not correspond to the speaker's conscious attitudes. Two main topics are addressed: the relation between insincerity and the saying-meaning distinction, and the mental attitude underlying insincere speech. The account is applied to both assertoric and non-assertoric utterances of declarative sentences, and to utterances of non-declarative sentences. It is shown how the account gives the right (...) results for a range of cases. (shrink)

In what follows, I appeal to Charles Babbage’s discussion of the division of mental labor to provide evidence that—at least with respect to the social acquisition, storage, retrieval, and transmission of knowledge—epistemologists have, for a broad range of phenomena of crucial importance to actual knowers in their epistemic practices in everyday life, failed adequately to appreciate the significance of socially distributed cognition. If the discussion here is successful, I will have demonstrated that a particular presumption widely held within the contemporary (...) discussion of the epistemology of testimony—a presumption that I will term the personalist requirement—fails to account for those very practices of knowers that I detail here. I will then conclude by suggesting that an alternate account of testimonial warrant, one that has heretofore been underappreciated, ought to be given more serious consideration—in particular because it is well suited to account for those actual practices of knowers that the personalist requirement leaves unrecognized.

How does the monitoring of a testifier's credibility by recipients of testimony bear upon the epistemic licence accruing to a recipient's belief in the testifier's communications? According to an intuitive and philosophically influential conception, licensed acceptance of testimony requires that recipients of testimony monitor testifiers with respect to their credibility. I argue that this conception, however, proves to be untenable when confronted with the wealth of empirical evidence bearing on the ways in which testifiers and their interlocutors actually interact.

Some recent accounts of testimonial warrant base it on trust, and claim that doing so helps explain asymmetries between the intended recipient of testimony and other non-intended hearers, e.g. differences in their entitlement to challenge the speaker or to rebuke the speaker for lying. In this explanation ‘dependence-responsiveness’ is invoked as an essential feature of trust: the trustor believes the trustee to be motivationally responsive to the fact that the trustor is relying on the trustee. I argue that dependence-responsiveness is (...) not essential to trust and that the asymmetries, where genuine, can be better explained without reference to trust. (shrink)

The overwhelming consensus amongst epistemologists is that there is no salient epistemological difference between the addressees of a speaker’s testimony and non-addressees. I argue that this overwhelming consensus is mistaken. Addressees of a speaker’s testimony are entitled to pass the epistemic buck or defer justificatory responsibility for their beliefs back to the testimonial speaker, while non-addressees are not. I then develop a provisional account of address that is in a position to mark this epistemic distinction between addressees and non-addressees.

According to the Interpersonal View of Testimony, testimonial justification is non-evidential in nature. I begin by arguing that the IVT has the following problem: If the IVT is true, then young children and people with autism cannot participate in testimonial exchanges; but young children and people with autism can participate in testimonial exchanges; thus, the IVT should be rejected on the grounds that it has over-cognized what it takes to give and receive testimony. Afterwards, I consider what I take to (...) be the two best motivations for the IVT and argue that they both fail. The overarching lesson, then, is that the IVT is unmotivated and false; we should think of testimonial justification as being evidential in nature. (shrink)

The context or manner of an utterance can alter or nullify the speech-act that would normally be performed by utterances of that sort. Coercive contexts have this effect on some kinds of seeming assertions: they end up being non-assertoric, and are merely capitulations. An earlier version of this view is clarified, defended, and extended partly in response to a useful critique by Roy Sorensen. I examine some complications that arise regarding resistance to speaking under coercion when ideological or religious commitments (...) are implicated. (shrink)

Abstract: One oft-cited feature of speech acts is their expressive character: Assertion expresses belief, apology regret, promise intention. Yet expression, or at least sincere expression, is as I argue a form of showing: A sincere expression shows whatever is the state that is the sincerity condition of the expressive act. How, then, can a speech act show a speaker's state of thought or feeling? To answer this question I consider three varieties of showing, and argue that only one of them (...) is suited to help us answer our question. I also argue that concepts from the evolutionary biology of communication provide one source of insight into how speech acts enable one to show, and thereby express, a psychological state. (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.

What is it for a speech act to be sincere? The most common answer amongst philosophers is that a speech act is sincere if and only if the speaker is in the state of mind that the speech act functions to express. However, a number of philosophers have advanced counterexamples purporting to demonstrate that having the expressed state of mind is neither necessary nor sufficient for speaking sincerely. One may nevertheless doubt whether these considerations refute the orthodox conception. Instead, it (...) may be argued, they expose other ways of elucidating sincerity in speech. “Sincerity in speech” is ambivalent between a number of different conceptions. Against this background this paper presents two alternative conceptions, viz., Sincerity as Spontaneity and Sincerity as Presenting Oneself as one takes Oneself to be and develops a third conception which we may call Sincerity as a Communicative Virtue. This conception emphasizes the speaker’s intention in communicating her attitudes and the need to be properly justified in saying what one does. (shrink)
