I argue for the Cooperative Warrant Thesis (CWT), according to which the determinants of testimonial contents in communication are given by the practical requirements of cooperative action. This thesis distances itself from conventionalist views, according to which testimony must be strictly bounded by conventions of speech. CWT proves explanatorily better than conventionalism on several accounts. It offers a principled and accurate criterion to distinguish between testimonial and non-testimonial communication. In being goal-sensitive, this criterion captures the role of weak and robust (...) cooperation in determining the contents to which speakers testify or fail to testify. And, finally, it yields a principled explanation of why testimony entails the epistemic commitments that distinguish it as an epistemic source. (shrink)

It seems plausible that successfully communicating with our peers requires entertaining the same thoughts as they do. We argue that this view is incompatible with other, independently plausible principles of thought individuation. Our argument is based on a puzzle inspired by the Kripkean story of Peter and Paderewski: having developed several variations of the original story, we conclude that understanding and communication cannot be modeled as a process of thought transfer between speaker and hearer. While we are not the first (...) to reach this conclusion, the significance of our argument lies in the fact that it only relies on widely accepted premises, without depending on any especially controversial theory of mental and linguistic content. We conclude by drawing out the implications of that conclusion: if communication and understanding do not require thought identity, then one important motivation for the postulation of inter-personally shared thoughts is undercut.

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.

I argue that assertoric content functions as a means for us to track the responsibilities undertaken by communicators, and that distinctively assertoric commitments are distinguished by being generated directly in virtue of the words the speaker uses. This raises two questions: (a) Why are speakers responsible for the content thus generated? (b) Why is it important for us to distinguish between commitments in terms of their manner of generation? I answer the first question by developing a novel responsibility based metasemantics. (...) I answer the second by reference to the conflicting pressures governing the resources we have available for appraising speech. (shrink)

Those in the Gricean tradition take it that successful human communication features an audience who not only arrives at the intended content of the signal, but also recognizes the speaker’s intention that they do so. Some in this tradition have also argued that there are yet further conditions on communicative success, which rule out the possibility of communicating by luck. Supposing that both intention-recognition and some sort of anti-luck condition are correctly included in an analysis of human communication, this article (...) asks what the value of events satisfying these conditions is. I present a puzzle concerning the value of intention-recognition which is analogous to the Meno Problem in epistemology, but ultimately argue that this puzzle is solveable: the signaling-relevant value of intention recognition can be vindicated. However, I argue that the version of this puzzle that concerns the further proposed luck-proofing conditions on communication can not be answered. I argue therefore that communication, as analyzed by many, is no more valuable qua signal than a proper subset of its conditions. Human communication is thennot a uniquely valuable signaling event.

How good are we at understanding what others communicate? It often seems to us, at least, that we understand quite well what others convey when speaking in a familiar language. However, a growing body of evidence from the psychology of language suggests that in various communicative settings comprehenders routinely form linguistic representations that are underdetermined, “sketchy”, “shallow” or imprecise, often without noticing it. The paper discusses some important consequences of this evidence. Following recent discussions in this strand of research, I (...) outline how the evidence is currently best interpreted as supporting a view on which operating at a certain level of imprecision and underdetermination is a functional feature of the system responsible for comprehension of linguistic utterances in humans. That this kind of imprecision and underdetermination is part and parcel of linguistic interactions, makes the exact success rate of comprehension particularly hard to estimate. This poses a unique and interesting challenge for assessing the quality of linguistic comprehension. Understanding what a speaker intended to convey with a linguistic utterance may be less transparent than it appears to us. I will discuss the extent to which this evidence may lead to pessimism about how good we are at comprehending what others communicate. However, as I will argue in the last part of the paper, in various cases language users can be sensitive to some types of imprecision and underdetermination in comprehension and make up for it by means of various forms of post hoc deliberation. I will describe some such clarificatory contexts and end by charting a map of important issues that require further investigation. (shrink)

This thesis investigates the nature of the relation between mental representations in successful verbal communication, thought attribution, agreement, and disagreement — a relation which I call “samethinking”. The nature of samethinking raises several foundational questions about the nature of (non-natural) meaning, and the cognitive underpinnings of the emergence of culture. It bears on long-lasting puzzles in the philosophy of mind and language (such as Frege’s puzzle and Kripke’s puzzle about belief). Samethinking does not amount to sharing a reference (with “sharing" (...) I refer to two or more thinkers having something in common): it is more demanding. How can we explain and characterize this relation, more stringent than coreference, that is instantiated by a pair of thoughts when samethinking takes place? It is often assumed that this relation involves sharing a thought content more fine-grained than reference. In this thesis, I argue that the issue is more complex than what has been commonly assumed, and I suggest an alternative model in which sharing thought content is not necessary. (shrink)
