This paper states three counterexamples to the claim that testimony cannot generate knowledge, that a hearer can only acquire testimonial knowledge from a speaker who knows: a twins case, the fossil case, and an inversion case. The paper provides an explanation for why testimony can generate knowledge. Testimonial knowledge involves the flow of information from a speaker to a hearer through the linguistic channel.

La philosophie médiévale du langage présente deux séries d’affinités remarquables avec les approches contemporaines. L’une se situe du côté des sémantiques formelles et, plus généralement, des analyses logiques des conditions de vérité des énoncés. L’autre relève plutôt de la pragmatique, notamment des perspectives contextuelles sur les actes de langage. Les logiciens, grammairiens et théologiens du Moyen Âge étaient, de fait, pleinement conscients qu’ils avaient à leur disposition deux types d’approche des énoncés, selon qu’ils prenaient en compte les seules propriétés sémantiques (...) de leurs composants ou qu’ils intégraient des considérations extralinguistiques allant de l’intention des auteurs / locuteurs à leur statut, en passant par le contexte d’énonciation. Chacune de ces perspectives a bénéficié d’un certain nombre d’études récentes ; la question que je voudrais aborder est plutôt celle de leur frontière en logique, de son emplacement, ses déplacements, sa porosité éventuelle. La complexité des matériaux en jeu ne permettra pas de proposer plus que quelques points de repères, qui peuvent toutefois aider à évaluer l’hypothèse d’un « projet formel » en sémantique médiévale.

Far from being of interest only to argumentation theorists, conceptions of speech acts play an important role in practitioners’ self-reflection on their own activities. After a brief review of work by Houtlosser, Jackson and Kauffeld on the ways that speech acts provide normative frameworks for argumentative interactions, this essay examines an ongoing debate among scientists in natural resource fields as to the appropriateness of the speech act of advocating in policy settings. Scientists’ reflections on advocacy align well with current scholarship, (...) and the scholarship in turn can provide a deeper understanding of how to manage the communication challenges scientists face.

Searle’s (1963/1991) account of the communicative intentions in speech acts purports to be an advance over that of Grice (1957), in acknowledging the ineliminable role of the linguistic (usage) rules in enabling the hearer to recognize the speaker’s communicative intentions. In this paper we argue that, given some plausible assumptions about ordinary speech exchanges, Searle’s insight on this score is incompatible with his (1983) commitment to internalism in the philosophy of mind. As a result, Searle cannot have it both ways: (...) either he must give up his core insight regarding the ineliminable role of linguistic (usage) rules in the hearer’s recognition of a speaker’s communicative intentions, or he must give up his commitment to internalism the philosophy of mind. We conclude by arguing that this lesson is generic: the forced choice is one thatalltheorists must face, insofar as we theorize about the role of language in the communication of thought through speech.

This paper explores the relationship between dynamic and truth conditional semantics for epistemic modals. It provides a generalization of a standard dynamic update semantics for modals. This new semantics derives a Kripke semantics for modals and a standard dynamic semantics for modals as special cases. The semantics allows for new characterizations of a variety of principles in modal logic, including the inconsistency of ‘p and might not p’. Finally, the semantics provides a construction procedure for transforming any truth conditional semantics (...) for modals into a dynamic semantics for modals with similar properties. (shrink)

A “sender–receiver” framework based on models developed in several fields can provide a general treatment of communicative and symbolic phenomena, replacing traditional semiotic theories that have failed to live up to the hopes of their advocates. Sender–receiver models have mostly been applied to linguistic behavior, gestures, and other ephemeral interactions between individuals. I look at the application of this framework to enduring artifacts, including pictures, using indigenous rock art in Australia as a case study.

I expand upon Kristie Dotson's concept of “epistemic violence” by identifying another type of epistemic violence that arises in the context of nonverbal communication. “Emotional misperception,” as I call it, occurs when the following conditions are met: A misreads B's nonlinguistic expression of emotion, owing to reliable ignorance, harming B.

I defend the normativity of meaning against recent objections by arguing for a new interpretation of the ‘ought’ relevant to meaning. Both critics and defenders of the normativity thesis have understood statements about how an expression ought to be used as either prescriptive or semantic. I propose an alternative view of the ‘ought’ as conveying the primitively normative attitudes speakers must adopt towards their uses if they are to use the expression with understanding.

Do axiomatic derivations advance positive economics? If economists are interested in predicting how people behave, without a pretense to change individual decision making, how can they benefit from representation theorems, which are no more than equivalence results? We address these questions. We propose several ways in which representation results can be useful and discuss their implications for axiomatic decision theory.

Los juegos de palabras no buscados, los actos fallidos, los erroresconceptuales, evocan significados que son independientes de la intención del hablante. Pero las teorías filosóficas y lingüísticas dedicadasal estudio de la comunicación y los procesos cognitivos se dedican exclusiva ofundamentalmente al significado intencional. Espero mostrar aquí que la “falacia intencional” de Wimsatt y Beardsley , que establecía que la intención delautor no determina la interpretación, es una buena base para empezar a sugerir que los significados no intencionales también son importantes (...) en la interpretación de toda clase de enunciados. La teoría de redes relacionales es un enfoque neurocognitivo del lenguaje que puede tratar los significados no intencionales de un modo comparable al sugerido por autores representativos del New Criticism, sin descuidar por ello la importancia del significado intencional.

Each of these books offers a richly developed and nuanced account of the nature of fiction. And each poses major challenges to a view about which there is a near-consensus. Catharine Abell draws on a theory of the institutions of fiction to advance a systematic re-envisioning of the metaphysics and epistemology of the contents of stories. Gregory Currie argues that fiction’s relationship to the imagination, and the way stories communicate their contents to readers, seriously undermine fiction’s cognitive values.

I argue for an intentional conception of representation in science that requires bringing scientific agents and their intentions into the picture. So the formula is: Agents (1) intend; (2) to use model, M; (3) to represent a part of the world, W; (4) for some purpose, P. This conception legitimates using similarity as the basic relationship between models and the world. Moreover, since just about anything can be used to represent anything else, there can be no unified ontology of models. (...) This whole approach is further supported by a brief exposition of some recent work in cognitive, or usage-based, linguistics. Finally, with all the above as background, I criticize the recently much discussed idea that claims involving scientific models are really fictions. (shrink)

What role do speakers'/authors’ communicative intentions play in language interpretation? Cognitive scientists generally assume that listeners'/readers’ recognitions of speakers'/authors’ intentions is a crucial aspect of utterance interpretation. Various philosophers, literary theorists and anthropologists criticize this intentional view and assert that speakers'/authors’ intentions do not provide either the starting point for linguistic interpretation or constrain how texts should be understood. Until now, cognitive scientists have not seriously responded to the current challenges regarding intentions in communication. My purpose in this article is (...) to provide just such a response. I briefly describe some of the empirical evidence in cognitive science on the importance of intentions in communication. I then discuss some of the criticisms of the intentional view that have arisen in the humanities and social sciences. Following this, I offer a partial resolution to the intentionalist controversy that recognizes the differing views on the idea of linguistic interpretation. I specifically suggest a way of thinking about linguistic interpretation in terms of the time‐course of understanding that provides a metric for evaluating the role of intentions in communication. This time‐course perspective on linguistic understanding provides for the plurality of ideas that now exist both in cognitive science and in postmodern philosophical thought. (shrink)

Multivariate pattern analysis, or MVPA, has become one of the most popular analytic methods in cognitive neuroscience. Since its inception, MVPA has been heralded as offering much more than regular univariate analyses, for—we are told—it not only can tell us which brain regions are engaged while processing particular stimuli, but also which patterns of neural activity represent the categories the stimuli are selected from. We disagree, and in the current paper we offer four conceptual challenges to the use of MVPA (...) to make claims about neural representation. Our view is that the use of MVPA to make claims about neural representation is problematic. (shrink)

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.

This paper investigates the relation between what James Conant has called Kantian and Cartesian varieties of skepticism. It is argued that a solution to the most prominent example of a Kantian variety of skepticism, i.e. Kripkensteinian skepticism about rule-following and meaning, can be found in the works of Wilfrid Sellars. It is then argued that, on the basis of that very same solution to the Kantian problematic of rule-following and meaning, a novel argument against external world skepticism can be formulated. (...) This argument takes the shape of a transcendental argument, which is reminiscent of Hilary Putnam’s infamous argument against the brain-in-a-vat hypothesis, but is, as is argued, superior to it in certain respects.

In this paper, I analyze the concept of ineffability: what does it mean to say that something cannot be said? I begin by distinguishing ineffability from paradox: if something cannot be said truly or without contradiction, this is not an instance of ineffability. Next, I distinguish two different meanings of ‘saying something’ which result from a fundamental ambiguity in the term ‘language’, viz. language as a system of symbols and language as a medium of communication. Accordingly, ‘ineffability’ is ambiguous, too, (...) and we should make a distinction between weak and strong ineffability. Weak ineffability is rooted in the deficiencies of a particular language while strong ineffability stems from the structure of a particular cognitive system and its capacities for conceptual mental representation. Mental contents are only sayable if we are able to conceptualize them and then create signs to represent them in communication. (shrink)

Some speech acts are made indirectly. It is thus natural to think that assertions could also be made indirectly. Grice’s conversational implicatures appear to be just a case of this, in which one indirectly makes an assertion or a related constative act by means of a declarative sentence. Several arguments, however, have been given against indirect assertions, by Davis (1999), Fricker (2012), Green (2007, 2015), Lepore & Stone (2010, 2015) and others. This paper confronts and rejects three considerations that have (...) been made: arguments based on the distinction between lying and misleading; arguments based on the ordinary concept of assertion; and arguments based on the testimonial knowledge that assertions provide.

Only Imagine is a wonderful book. Clear and tersely written, it provides a compelling defence of a rather unpopular view : namely, extreme intentionalism about the determination of fictional content and the nature of fictionality. It thus unquestionably advances the philosophical debate. It is also a pleasure to read for those of us who like fictions and not just the philosophy thereof: Stock discusses for her arguments many examples from real fictions, systematically making perceptive remarks. Here I will respond to (...) an objection that she makes to the normative account that I have defended in previous work, arguing that it has explanatory advantages grounded on the subordination on that account of author-intentions to fictional contents independently determined by social practices.

Dialog is a joint action at different levels. At the highest level, the goal of interlocutors is to align their mental representations. This emerges from joint activity at lower levels, both concerned with linguistic decisions (e.g., choice of words) and nonlinguistic processes (e.g., alignment of posture or speech rate). Because of the high‐level goal, the interlocutors are particularly concerned with close coupling at these lower levels. As we illustrate with examples, this means that imitation and entrainment are particularly pronounced during (...) interactive communication. We then argue that the mechanisms underlying such processes involve covert imitation of interlocutors’ communicative behavior, leading to emulation of their expected behavior. In other words, communication provides a very good example of predictive emulation, in a way that leads to successful joint activity. (shrink)

The paper distinguishes between two conceptions of kinds defined by constitutive rules, the one suggested by Searle, and the one invoked by Williamson to define assertion. Against recent arguments to the contrary by Maitra, Johnson and others, it argues for the superiority of the latter in the first place as an account of games. On this basis, the paper argues that the alleged disanalogies between real games and language games suggested in the literature in fact don’t exist. The paper relies (...) on Rawls’s distinction between types of practices and institutions defined by constitutive rules, and those among them that are actually in force, and hence are truly normative; it defends along Rawlsian lines that a plurality of norms apply to actual instances of rule-constituted practices, and uses this Rawlsian line to block the examples that Maitra, Johnson and others provide to sustain their case.

Contemporary semantics assumes two influential notions of context: one coming from Kaplan (1989), on which contexts are sets of predetermined parameters, and another originating in Stalnaker (1978), on which contexts are sets of propositions that are “common ground”. The latter is deservedly more popular, given its flexibility in accounting for context-dependent aspects of language beyond manifest indexicals, such as epistemic modals, predicates of taste, and so on and so forth; in fact, properly dealing with demonstratives (perhaps ultimately all indexicals) requires (...) that further flexibility. Even if we acknowledge Lewis (1980)’s point that, in a sense, Kaplanian contexts already include common ground contexts, it is better to be clear and explicit about what contexts constitutively are. Now, Stalnaker (1978, 2002, 2014) defines context-as-common-ground as a set of propositions, but recent work shows that this is not an accurate conception. The paper explains why, and provides an alternative. The main reason is that several phenomena (presuppositional treatments of pejoratives and predicates of taste, forces other than assertion) require that the common ground includes non-doxastic attitudes such as appraisals, emotions, etc. Hence the common ground should not be taken to include merely contents (propositions), but those together with attitudes concerning them: shared commitments, as I will defend.

We can use radically different reference‐schemes to generate the same truth‐conditions for the sentences of a language. In this paper, we do three things. (1) Distinguish two arguments that deploy this observation to derive different conclusions. The first argues that reference is radically indeterminate: there is no fact of the matter what ordinary terms refer to. This threat is taken seriously and most contemporary metasemantic theories come with resources intended to rebut it. The second argues for radical parochialism about reference: (...) it's a reflection of our parochial interests, rather than the nature of the subject matter, that our theorizing about language appeals to reference rather than another relation that generates the same truth‐conditions. Rebuttals of the first argument cut no ice against the second, because radical parochialism is compatible with reference being determinate. (2) Argue that radical parochialism, like radical indeterminacy, would be shocking if true. (3) Argue that the case for radical parochialism turns on the explanatory purposes of “reference”‐talk: on relatively “thin” conceptions, the argument goes through, and radical parochialism is (shockingly!) true; on richer conceptions, the argument can be blocked. We conclude that non‐revisionists must endorse, and justify, a relatively rich conception of the explanatory purposes of “reference”‐talk. (shrink)

In recent decades, philosophers of science have devoted considerable efforts to understand what models represent. One popular position is that models represent fictional situations. Another position states that, though models often involve fictional elements, they represent real objects or scenarios. Though these two positions may seem to be incompatible, I believe it is possible to reconcile them. Using a threefold distinction between different signs proposed by Peirce, I develop an argument based on a proposal recently made by Kralemann and Lattman (...) (in Synthese 190:3397–3420, 2013) that shows that the two aforementioned positions can be reconciled by distinguishing different ways in which a model representation can be used. In particular, on the basis of Peirce’s distinction between icons, indices and symbols, I argue that models can sometimes function as icons, sometimes as indexes and sometimes as symbols, depending on the context in which they are considered and the use that they are developed for because they all have iconic, indexical and symbolic features. In addition, I show that conceiving models as signs enables us to develop an account of scientific representation that meets the main desiderata that Shech (in Synthese 192:3463–3485, 2015) presents.

In this article, I provide an argument against the idea that public hate-speech events are harmful because they cause a discrete, traceable and harmful change in one’s propositional attitudes. To do so, I identify the essential conceptual architecture of public hate-speech situations, I assess existing arguments for the direct and indirect harm of public hate speech and I propose a novel way to approach public hate-speech situations: a maieutic approach. On this perspective, public hate-speech events do not cause changes in (...) propositional attitudes, but rather, if successful, either such events bring a person’s latent propositional attitudes into clear consciousness, or they play with propositional attitudes speakers and their audience had prior to the public hate-speech situation.

Advances in artificial intelligence (AI) create an increasing similarity between the performance of AI systems or AI-based robots and human communication. They raise the questions: whether it is possible to communicate with, understand, and even empathically perceive artificial agents; whether we should ascribe actual subjectivity and thus quasi-personal status to them beyond a certain level of simulation; what will be the impact of an increasing dissolution of the distinction between simulated and real encounters. (1) To answer these questions, the paper (...) argues that the precondition for actually understanding others consists in the implicit assumption of the subjectivity of our counterpart, which makes shared feelings and a „we-intentionality” possible. This assumption is ultimately based on the presupposition of a shared form of life, conceived here as „conviviality.” (2) The possibility that future artificial agents could meet these preconditions is refuted on the basis of embodied and enactive cognition, which links subjectivity and consciousness to the aliveness of an organism. (3) Even if subjectivity is in principle impossible for artificial agents, the distinction between simulated and real subjectivity might nevertheless become increasingly blurred. Here, possible consequences are discussed, especially using the example of virtual psychotherapy. Finally, the paper makes case for a mindful appproach to the language we use to talk about artificial systems and pleads for preventing a systematic pretense of subjectivity. (shrink)

The Exchange of Words, by MoranRichard. Oxford: OUP, 2018. Pp. 254.

We citizens of the 21st century live in a world where division of epistemic labour rules. Most of what we know we learned from the spoken or written word of others, and we depend in endless practical ways on the technological fruits of the dispersed knowledge of others—of which we often know almost nothing—in virtually every moment of our lives. Interest has been growing in recent years amongst philosophers, in the issues in epistemology raised by this fact. One issue concerns (...) the depth and extent of our epistemic dependence on testimony, as we may label this broad epistemic source: Do we have any knowledge at all that is free of epistemic dependence on what we have learned from others? A related question is whether our entitlement to believe what we have learned from others can be explained without invoking any epistemic principles special to testimony. These questions concern, as it were, the macro-epistemology of testimony. In the present discussion I shall focus instead on the micro foundations. Testimony, in our broad sense, can occur through an extensive range of types of spoken and written means of purportedly factual communication, including telephone calls, e-mails and personal letters, lectures and radio broadcasts, newspapers, textbooks and encyclopaedias, personal diaries, and public records of all kinds. But the central paradigm—what started the whole communication thing off—is surely that of face-to-face spoken encounter, when one person tells something to another, thereby intending and hoping to share her knowledge with her audience. I begin by describing the speech act of telling, identifying what takes place in a felicitous act of telling. From the nature of the speech act of telling, we see precisely how it is that knowledge is, when all goes as it should, acquired from teller by trusting hearer, in such an act, and in acts of testimony more broadly.

The claims that “The brain processes information” or “Cognition is information processing” are accepted as truisms in cognitive science. However, it is unclear how to evaluate such claims absent a specification of “information” as it is used by neurocognitive theories. The aim of this article is, thus, to identify the key features of information that information-based neurocognitive theories posit. A systematic identification of these features can reveal the explanatory role that information plays in specific neurocognitive theories, and can, therefore, be (...) both theoretically and practically important. These features can be used, in turn, as desiderata against which candidate theories of information may be evaluated. After discussing some characteristics of explanation in cognitive science and their implications for “information”, three notions are briefly introduced: natural, sensory, and endogenous information. Subsequently, six desiderata are identified and defended based on cognitive scientific practices. The global workspace theory of consciousness is then used as a specific case study that arguably posits either five or six corresponding features of information. (shrink)

The idea that the brain is an information processing system raises some challenging questions about whether information exists independently of brains. Answering these questions is relevant for clarifying the theoretical foundations of the sciences of mind and brain, but also for appropriately interpreting and evaluating the evidence about how brains—and other biological systems—work. This article claims that (1) informational descriptions in the sciences of mind and brain can be genuinely explanatory, despite assuming a mind-dependent notion of information; and (2) that (...) either Popperian objectivity or response-dependence in normal receivers is sufficient for grounding the explanatory role that information often plays in these sciences. Hierarchical predictive processing, which has become a central theoretical framework for neurocognitive research, is used as a case study for supporting these two claims. (shrink)

There are many different notions of information in logic, epistemology, psychology, biology and cognitive science, which are employed differently in each discipline, often with little overlap. Since our interest here is in biological processes and organisms, we develop a taxonomy of functional information that extends the standard cue/signal distinction. Three general, main claims are advanced here. This new taxonomy can be useful in describing learning and communication. It avoids some problems that the natural/non-natural information distinction faces. Functional information is​ ​produced (...) through exploration and stabilisation processes. (shrink)

Bullot & Reber (B&R) put forth a design stance to fuse psychological and art historical accounts of visual thinking into a single theory. We argue that this aspect of their proposal needs further fine-tuning. Issues of transgression and coherence are necessary to provide stability to the design stance. We advocate looking to Art Education for such fundamentals of picture understanding.

In this paper, I look at Susan Stebbing’s articles and reviews that critically engage logical positivism. These appeared before the publication of A.J. Ayer’s Language, Truth and Logic and helped shape the early British reception of logical positivism. I highlight Stebbing’s adoption of G.E. Moore’s tripartite distinction between knowing a proposition, understanding it, and giving an analysis of it and, in light of this distinction, her focus on whether the principle of verifiability can ground a plausible account of communication. Stebbing (...) thinks not, and I reconstruct her reasons, as well as her own account of communication. In doing this, I relate her criticisms to her rejection of methodological solipsism and her dissatisfaction with the logical positivist treatment of statements about other minds and the past. I also argue that Stebbing’s work provides a bridge to later criticisms of logical positivism from ordinary language philosophers. Foregrounding Stebbing’s engagement with logical positivism, especially her focus on communication, paints a fuller picture of how the logical positivists came to be part of analytic philosophy despite having different concerns than many of the British philosophers engaging their work.

Logical Holism and Wittgenstein’s ‘Practical Turn’. – Logical holism is the idea that each elementary proposition belongs to a system and is logically connected to other propositions of that system. In this paper I explore this idea and draw its connections to the nature of negative propositions and the ‘problem of recognition’ on the basis of Wittgenstein’s Nachlass. In the first section I argue that in January 1930 the idea leads Wittgenstein to a better understanding of how the negative feature (...) is expressed in propositions, thereby raising the problem of recognition to which he is not yet able to find a proper solution. In the second section I explore how the problem still persists during Wittgenstein’s ‘practical turn’. What he now calls the ‘problem of representation’ forces him to change again his conception of propositions. In the final section I argue that this change is mainly due to the modification of his conception of hypotheses which urges a solution to the problem of representation, though the problem remains unsolved in January 1930.

This article motivates a shift in certain strands of the debate over legitimate roles for nonepistemic values in scientific practice from investigating what is involved in taking cognitive attitudes like acceptance toward an empirical hypothesis to looking at a social understanding of assertion, the act of communicating that hypothesis. I argue that speech act theory’s account of assertion as a type of doing makes salient legitimate roles nonepistemic values can play in scientific practice. The article also shows how speech act (...) theory might provide a framework for fruitfully extending aspects of the social and pragmatic turns in the philosophy of science. (shrink)
