Today, the earth is an interconnected globe humming with electronic transmissions-a chattering planet nestled in the provident silence of space. The ethical question is whether this is contributing to authentic human development and helping individuals and peoples to be true to their transcendent destiny. The new media are powerful tools for education, cultural enrichment, commercial activity, political participation, intercultural dialogue and understanding. They also can serve the cause of religion. Yet the new information technology needs to be informed and guided (...) by solidarity in the service of the common good bridging the digital divide within and among nations. The value-laden message of Western secular culture to people and traditional societies in many cases ill-prepared to evaluate it leads to widespread crisis, for example, in regard to marriage and family life. This technology can be a means for solving human problems, promoting the integral development of persons, creating a world governed by justice, peace, and love. It also can help men and women in their age-old search for self-understanding. Like today's world itself, the world of media, including the Internet, has been brought by Christ, inchoately yet truly, within the boundaries of the kingdom of God and placed in service to the word of salvation.

It is sometimes claimed that Gricean communication is necessarily a form of cooperative or ‘joint’ action. A consequence of this Cooperative Communication View is that Gricean communication could not itself contribute to an explanation of the possibility of joint action. I argue that even though Gricean communication is often a form of joint action, it is not necessarily so—since it does not always require intentional action on the part of a hearer. Rejecting the Cooperative Communication (...) View has attractive consequences for our theorising about human cognitive development, since it opens up the possibility of appealing to communicative interaction to explain the emergence of joint action in phylogeny.

Humans alone acquire language. According to one influen- tial school of thought, we do this because we possess a uniquely human ability to act with and attribute “Gricean” communicative intentions. A challenge for this view is that attributing communicative intent seems to require cognitive abilities that infant language learners lack. After considering a range of responses to this challenge, I argue that infant language development can be explained, because Gricean communication is cognitively less demanding than many suppose. However, a (...) consequence of this is that abilities for Gricean communication are unlikely to be uniquely human. (shrink)

Many important theorists – e.g., Gary Watson and Stephen Darwall – characterize blame as a communicative entity and argue that this entails that morally responsible agency requires not just rational but moral competence. In this paper, I defend this argument from communication against three objections found in the literature. The first two reject the argument’s characterization of the reactive attitudes. The third urges that the argument is committed to a false claim.

Most people working on linguistic meaning or communication assume that semantics and pragmatics are distinct domains, yet there is still little consensus on how the distinction is to be drawn. The position defended in this paper is that the semantics/pragmatics distinction holds between encoded linguistic meaning and speaker meaning. Two other ‘minimalist’ positions on semantics are explored and found wanting: Kent Bach’s view that there is a narrow semantic notion of context which is responsible for providing semantic values for (...) a small number of indexicals, and Herman Cappelen and Ernie Lepore’s view that semantics includes the provision of values for all indexicals, even though these depend on the speaker’s communicative intentions. Finally, some implications are considered for the favoured semantics/pragmatics distinction of the fact that there are linguistic elements which do not contribute to truth-conditional content but rather provide guidance on pragmatic inference.

Codes of ethics currently offer no guidance to scientists acting in capacity of expert. Yet communicating their expertise is one of the most important activities of scientists. Here I argue that expert communication has a specifically ethical dimension, and that experts must face a fundamental trade-off between "actionability" and "transparency" when communicating. Some recommendations for expert communication are suggested.

According to the communication desideratum (CD), a notion of semantic content must be adequately related to communication. In the recent debate on indexical reference, (CD) has been invoked in arguments against the view that intentions determine the semantic content of indexicals and demonstratives (intentionalism). In this paper, I argue that the interpretations of (CD) that these arguments rely on are questionable, and suggest an alternative interpretation, which is compatible with (strong) intentionalism. Moreover, I suggest an approach that combines (...) elements of intentionalism with other subjectivist approaches, and discuss the role of intuitions in developing and evaluating theories of indexical reference.

This book discusses key ethical and deontological problems concerning the use of the most common information and communication devices. It focuses on the challenges of the new environments we now find ourselves in thanks to these technologies, and the issues arising from the newly established relationship between the virtual sphere and the real world. Each aspect is analysed by starting from a very specific example or a case study presenting a dilemma that can only be resolved by making a (...) reasoned ethical choice. Rather than thematically addressing only one of the many aspects mentioned above, the book presents a comprehensive introduction to, and a co-ordinated overview of, the various deontological and ethical issues regarding the spread of the most common information and communication technologies.

The Experience of Human Communication approaches everyday communication as a philosophical and psychological matter. Using insights from Merleau-Ponty, Heidegger, and Foucault, Frank Macke stresses that human communication—and with it, the human body—is, first and foremost, a relational phenomenon involving friends and family.

New definitions are proposed for communication and language. Communication is defined as the evolution of physical, biochemical, cellular, community, and technological information exchange. Language is defined as community communication whereby the information exchanged comprises evolving individual and group-constructed knowledge and beliefs, that are enacted, narrated, or otherwise conveyed by evolving rule-governed and meaningful symbol systems, that are grounded, interpreted, and used from within evolving embodied, cognitive, ecological, sociocultural, and technological niches. These definitions place emphasis on the evolutionary (...) aspects of communication and language, and they are here differentiated from four older paradigms that instead focus either on the referential or social aspects of language, or the informational or semantic aspects of communication. In contrast with these paradigms, the definitions proposed here for communication and language are in line with a pluralistic evolutionary worldview, one that necessitates the recognition that a multitude of units, levels, mechanisms and processes are involved in bringing forth communication and language.

A satisfactory theory of linguistic communication must explain how it is that, through the interpersonal exchange of auditory, visual, and tactile stimuli, the communicative preconditions for the acquisition of testimonial knowledge regularly come to be satisfied. Without an account of knowledge-yielding communication this success condition for linguistic theorizing is left opaque, and we are left with an incomplete understanding of testimony, and communication more generally, as a source of knowledge. This paper argues that knowledge-yielding communication should (...) be modelled on knowledge itself. It is argued that knowledge-yielding communication occurs iff interlocutors coordinate on truth values in a non-lucky and non-deviant way. This account is able to do significant explanatory work: it sheds light on the nature of referential communication, and it allows us to capture, in an informative way, the sense in which interlocutors must entertain similar propositions in order to communicate successfully.

In this important volume Habermas outlines the views which form the basis of his critical theory of modern societies. The volume comprises five interlocking essays, which together define the contours of his theory of communication and of his substantive account of social change. ′What is Universal Pragmatics?′ is the best available statement of Habermas′s programme for a theoryof communication based on the analysis of speech acts. In the following two essays Habermas draws on the work of Kohlberg and (...) others to develop a distinctive account of moral consciousness and normative structures. ′Toward a Reconstruction of historical Materialsim′ takes these issues further, offering a wide–ranging reconstruction of Marx′s historical materialsim understood as a theory of social evolution. The final essay focuses on the question of legitimacy and on the legitimation problems faced by modern states. This book is essential reading for anyone concerned with the key questions of social and political theory today. (shrink)

Donald Griffin has suggested that cognitive ethologists can use communication between non-human animals as a "window" into animal minds. Underlying this metaphor seems to be a conception of cognition as information processing and communication as information transfer from signaller to receiver. We examine various analyses of information and discuss how these analyses affect an ongoing debate among ethologists about whether the communicative signals of some animals should be interpreted as referential signals or whether emotional accounts of such signals (...) are adequate. We discuss the food-calling behavior of a group of rhesus monkeys to develop these issues. (shrink)

In this paper, we are interested in how a company can enhance stakeholder involvement in its information-sharing practices. We start by looking at the current information-sharing practices in a case where Europe’s second largest pulp producer Metsä-Botnia was caught in the middle of a heated debate between two countries when building a pulp mill in South America. We examine the content of the company’s press releases in terms of the degree of stakeholder involvement. On the basis of our analysis, we (...) discuss the problems and possibilities of enhancing stakeholder involvement through information sharing by introducing a discursive understanding to stakeholder dialogue.

Communication by scientists with policy makers and attentive publics raises ethical issues. Scientists need to decide how to communicate knowledge effectively in a way that nonscientists can understand and use, while remaining honest scientists and presenting estimates of the uncertainty of their inferences. They need to understand their own ethical choices in using scientific information to communicate to audiences. These issues were salient in the Fourth Assessment of the Intergovernmental Panel on Climate Change with respect to possible sea level (...) rise from disintegration of the Greenland and West Antarctic ice sheets. Due to uncertainty, the reported values of projected sea level rise were incomplete, potentially leading some relevant audiences to underestimate future risk. Such judgments should be made in a principled rather than an ad hoc manner. Five principles for scientific communication under such conditions are important: honesty, precision, audience relevance, process transparency, and specification of uncertainty about conclusions. Some of these principles are of intrinsic importance while others are merely instrumental and subject to trade-offs among them. Scientists engaged in assessments under uncertainty should understand these principles and which trade-offs are acceptable. (shrink)

Language is both a biological and a cultural phenomenon. Our aim here is to discuss, in an evolutionary perspective, the articulation of these two aspects of language. For this, we draw on the general conceptual framework developed by Ruth Millikan (1984) while at the same time dissociating ourselves from her view of language.

This book marks an important evolution in Jean Baudrillard's thought as he leavesbehind his older and better-known concept of the "simulacrum" and tackles the new problem of digitaltechnology acquiring organicity. The resulting world of cold communication and its indifferentalterity, seduction, metamorphoses, metastases, and transparency requires a new form of response.Writing in the shadow of Marshall McLuhan, Baudrillard insists that the content of communication iscompletely without meaning: the only thing that is communicated is communication itself. He sees themasses (...) writhing in an orgiastic ecstasy of communications. Baudrillard navigates the Object'smaelstrom with the euphoria of the astronaut reentering Earth's atmosphere with no possibility ofassistance from Mission Control. (shrink)

Individuals of some animal species have been taught simple versions of human language despite their natural communication systems failing to rise to the level of a simple language. How is it, then, that some animals can master a version of language, yet none of them deploy this capacity in their own communication system? I first examine the key design features that are often used to evaluate language-like properties of natural animal communication systems. I then consider one candidate (...) animal system, bird song, because it has several of the key design features or their precursors, including social learning and cultural transmission of their vocal signals. I conclude that although bird song communication is nuanced and complex, and has the acoustic potential for productivity, it is not productive – it cannot be used to say many different things. Finally, I discuss the debate over whether animal communication should be viewed as a cooperative information transmission process, as we typically view human language, or as a competitive process where signaler and receiver vie for control. The debate points to a necessary condition for the evolution of a simple language that has generally been overlooked: the degree of to which the interests of the signaler and receiver align. While strong cognitive and signal production mechanisms are necessary pre-adaptations for a simple language, they are not sufficient. Also necessary is the existence of identical or near-identical interests of signaler and receiver and a socio-ecology that requires high-level cooperation across a range of contexts. In the case of our hominid ancestors, these contexts included hunting, gathering, child care and, perhaps, warfare. I argue that the key condition for the evolution of human language was the extreme interdependency that existed among unrelated individuals in the hunter-gatherer societies of our hominid ancestors. This extreme interdependency produced multiple prosocial adaptations for effective intragroup cooperation, which in partnership with advanced cognitive abilities, set the stage for the evolution of language.

Abstract:The ethical principle of autonomy requires physicians to respect patient autonomy when present, and to protect the patient who lacks autonomy. Fulfilling this ethical obligation when a patient has a communication impairment presents considerable challenges. Standard methods for evaluating decision-making capacity require a semistructured interview. Some patients with communication impairments are unable to engage in a semistructured interview and are at risk of the wrongful loss of autonomy. In this article, we present a general strategy for assessing decision-making (...) capacity in patients with communication impairments. We derive this strategy by reflecting on a particular case. The strategy involves three steps: (1) determining the reliability of communication, (2) widening the bandwidth of communication, and (3) using compensatory measures of decision-making capacity. We argue that this strategy may be useful for assessing decision-making capacity and preserving autonomy in some patients with communication impairments. (shrink)

Recent years have seen an upsurge of interest in the second-person perspective, not only in philosophy of mind, language, law and ethics, but also in various empirical disciplines such as cognitive neuroscience and developmental psychology. A distinctive and perhaps also slightly puzzling feature of this ongoing discussion is that whereas many contributors insist that a proper consideration of the second-person perspective will have an impact on our understanding of social cognition, joint action, communication, self-consciousness, morality, and so on, there (...) remains considerable disagreement about what exactly a second-person perspective amounts to (see Eilan 2014; Conant and Rödl 2014). What is the difference between adopting a second-person and a third-person perspective on another? How does one relate to another as a you and how does that differ from relating to another as a he, she or they? In the following, I will consider three different proposals and argue that a promising but somewhat overlooked account can be found in the work of Husserl. (shrink)

This volume provides a comprehensive account of Wilhelm Röpke as a liberal political economist and social philosopher. Wilhelm Röpke was a key protagonist of transatlantic neoliberalism, a prominent public intellectual and a gifted international networker. As an original thinker, he always positioned himself at the interface between political economy and social philosophy, as well as between liberalism and conservatism. Röpke’s endeavors to combine these elements into a coherent whole, as well as his embeddedness in European and American intellectual networks of (...) liberal and conservative thinkers, are a central theme throughout the book. The volume includes papers by international experts from a conference in Geneva on the occasion of the 50th anniversary of Röpke’s passing. The first part focuses on new biographical insights into his exile years in Istanbul and Geneva, while the second part discusses his business cycle theory in the context of the Great Depression, and the third part elaborates on his multifaceted social philosophy. Wilhelm Röpke was among the most important thinkers within the classical liberal revival post-WWII, with intriguing tensions between liberalism and conservatism. A highly recommended volume. –– Peter J. Boettke, 2016-2018 President of the Mont Pèlerin Society and Professor of Economics and Philosophy, George Mason University This important collection of papers provides an in-depth assessment of Wilhelm Röpke’s contributions, placing him in the context of his time. A fine contribution. –– Bruce J. Caldwell, Director of the Center for the History of Political Economy and Research Professor of Economics, Duke University. (shrink)

In "Global Spencerism" the authors analyse the communication and appropriation of Herbert Spencer s ideas around the globe. In the last quarter of the nineteenth century Spencer s distinctive theory of evolution, based on Lamarckianism, was almost as influential as Darwin s.".

How can expressivists make sense of the practice of communication? If communication is not a joint enterprise aimed at sharing information about the world, why do we engage in communication the way we do? Call this *the problem of communication*. Starting from basic assumptions about the rationality of speakers and the nature of assertion, we argue that speakers engaging in conversation about normative matters must presuppose that there is a unique normative standard on which the attitudes (...) of conversational participants ought to converge. This gives the beginning of a solution to the problem of communication on behalf of expressivists. (shrink)

Organizations today recognize that it is not only important to engage in corporate social responsibility, but that it is also equally important to ensure that information about CSR is communicated to audiences. At times, however, the CSR image perceived by audiences is not an accurate portrayal of the organization’s CSR identity and is, therefore, incongruent with the desired CSR image. In this paper, we build upon the nascent work on organizational impression management by examining CSR communication from an impression (...) management perspective. The model developed here proposes that incongruence between desired and current CSR images motivates an organization to decrease the incongruence through CSR communication. This relationship is moderated by four factors: importance of CSR image to the organization; power, status, and attractiveness of the target audience; importance of CSR image to the target audience; and media attention and public scrutiny. The model also identifies four dimensions of CSR communication structure and includes a feedback loop through which audience interpretation of the CSR communication can influence the organization’s CSR image incongruence. Two illustrative examples are provided to indicate how the model may be applied to organizations. This paper has several implications for research and practice. It draws connections between impression management theory and CSR and adds to the emerging literature on organizational impression management. It can also help organizations decide on the appropriate CSR communication structure to use in specific situations and be more effective in their CSR communication. (shrink)

According to standard assumptions in semantics, ordinary users of a language have implicit beliefs about the truth-conditions of sentences in that language, and they often agree on those beliefs. For example, it is assumed that if Anna and John are both competent users of English and the former utters ‘grass is green’ in conversation with the latter, they will both believe that that sentence is true if and only if grass is green. These assumptions play an important role in an (...) intuitively compelling picture of communication, according to which successful communication through literal assertoric utterances is normally effected thanks to our shared beliefs about the truth-conditions of the sentences uttered in the course of the conversation. Against these standard assumptions, this paper argues that the participants in a conversation rarely have the same beliefs about the truth-conditions of the sentences involved in a linguistic interaction. More precisely, it argues for Variance, the thesis that nearly every utterance is such that there is no proposition which more than one language user believes to be that utterance’s truth-conditional content. If Variance is true, we must reject the standard picture of communication. Towards the end of the paper I identify three ways in which ordinary conversations can be communication-like despite the truth of Variance and argue that the most natural amendments to the standard picture fail to explain them.

Recent research on bacteria and other microorganisms has provided interesting insights into the nature of life, cooperation, evolution, individuality or species. In this paper, I focus on the capacity of bacteria to produce molecules that are usually classified as ’signals’ and I defend two claims. First, I argue that certain interactions between bacteria should actually qualify as genuine forms of communication. Second, I use this case study to revise our general theories of signaling. Among other things, I argue that (...) a plausible requirement for a state to qualify as a signal is that it is a minimal cause. (shrink)

While a large social-choice-theoretic literature discusses the aggregation of individual judgments into collective ones, there is much less formal work on the transformation of judgments in group communication. I develop a model of judgment transformation and prove a baseline impossibility theorem: Any judgment transformation function satisfying some initially plausible conditions is the identity function, under which no opinion change occurs. I identify escape routes from this impossibility and argue that the kind of group communication envisaged by deliberative democats (...) must be "holistic": It must focus on webs of connected propositions, not on one proposition at a time, which echoes the Duhem-Quine "holism thesis" on scientific theory testing. My approach provides a map of the logical space in which different possible group communication processes are located. (shrink)

Although scientists dating back to Darwin have noted the importance of the body in communicating emotion, current research on emotion communication tends to emphasize the face. In this article we review the evidence for bodily expressions of emotions—that is, the handful of emotions that are displayed and recognized from certain bodily behaviors (i.e., pride, joy, sadness, shame, embarrassment, anger, fear, and disgust). We also review the previously developed coding systems available for identifying emotions from bodily behaviors. Although no extant (...) coding system provides an exhaustive list of bodily behaviors known to communicate a panoply of emotions, our review provides the foundation for developing such a system.

Beliefs are commonly analyzed as binary relations between subjects and propositions. Perry and Lewis have shown that the standard account has difficulties in handling self-locating beliefs. Robert Stalnaker has recently put forward a version of the standard account that is supposed to overcome this problem. Stalnaker's motivation for defending the propositional account of belief is that it comes with a simple and powerful propositional model of communication. In this paper I argue that Stalnaker's proposal fails. The only way of (...) upholding the propositional account of belief is by abandoning the simple account of communication. (shrink)

The question "What can justify criminal punishment ?" becomes especially insistent at times, like our own, of penal crisis, when serious doubts are raised not only about the justice or efficacy of particular modes of punishment, but about the very legitimacy of the whole penal system. Recent theorizing about punishment offers a variety of answers to that question-answers that try to make plausible sense of the idea that punishment is justified as being deserved for past crimes; answers that try to (...) identify some beneficial consequences in terms of which punishment might be justified; as well as abolitionist answers telling us that we should seek to abolish, rather than to justify, criminal punishment. This book begins with a critical survey of recent trends in penal theory, but goes on to develop an original account (based on Duff's earlier Trials and Punishments) of criminal punishment as a mode of moral communication, aimed at inducing repentance, reform, and reconciliation through reparation-an account that undercuts the traditional controversies between consequentialist and retributivist penal theories, and that shows how abolitionist concerns can properly be met by a system of communicative punishments. In developing this account, Duff articulates the "liberal communitarian" conception of political society (and of the role of the criminal law) on which it depends; he discusses the meaning and role of different modes of punishment, showing how they can constitute appropriate modes of moral communication between political community and its citizens; and he identifies the essential preconditions for the justice of punishment as thus conceived-preconditions whose non-satisfaction makes our own system of criminal punishment morally problematic. Punishment, Communication, and Community offers no easy answers, but provides a rich and ambitious ideal of what criminal punishment could be-an ideal of what criminal punishment cold be-and ideal that challenges existing penal theories as well as our existing penal theories as well as our existing penal practices.

Are communicators perceived as committed to what they actually say (what is explicit), or to what they mean (including what is implicit)? Some research claims that explicit communication leads to a higher attribution of commitment and more accountability than implicit communication. Here we present theoretical arguments and experimental data to the contrary. We present three studies exploring whether the saying–meaning distinction affects commitment attribution in promises, and, crucially, whether commitment attribution is further modulated by the degree to which (...) the hearer will actually rely on the promise. Our results support the conclusion that people perceive communicators to be committed to ‘what is meant’, and not simply to ‘what is said’. Our findings add to the experimental literature showing that the saying–meaning distinction is not as pivotal to social relations as often assumed, and that its role in commitment attribution might be overestimated. The attribution of commitment is strongly dependent on the (mutually known) relevance of ‘what is meant’. (shrink)

According to Grice's `Cooperative Principle', human communicators are involved in a cooperative endeavor. The speaker attempts to make herself understood and the listener, in turn, assumes that the speaker is trying to maximize the ease and effectiveness of communication. While pragmatists recognize that people do not always behave in such a way, the Cooperative Principle is generally assumed to hold. However, it is often the case that the interests of speakers and listeners diverge, at least to some degree. (...) class='Hi'>Communication can arise in such situations when the cost of signaling is high enough that it aligns the interests of speaker and listener, but what happens when the cost of signaling is not sufficient to align the interests of those communicating? In these cases the theoretical prediction is that they will reach a partially informative system of communication. Using methods from experimental economics, we test whether theoretical predictions are borne out. We find that subjects do learn to communicate without the cooperative principle. (shrink)

F. P. Ramsey pointed out in Theories that the observational content of a theory expressed partly in non-observational terms is retained in the sentence resulting from existentially generalizing the conjunction of all sentences of the theory with respect to all nonobservational terms. Such terms are thus avoidable in principle, but only at the cost of forming a single "monolithic" sentence. This paper suggests that communication may be thought of as occurring not only by sentence but by clause, a sentential (...) formula closed except for a special kind of variable. Understanding such clauses requires incorporating them within the scope of one's own Ramsey sentence. Many concepts of deductive and inductive logic carry over without great change. But the concepts of truth and designation are extendible to clauses only in the sense that assertions involving them must, to be understood, in turn be construed as clauses and incorporated into the Ramsey sentence. The behavior of these extended concepts of truth and designation suggests an explication of coherence truth within a correspondence-truth framework. (shrink)

Brian Loar [1976] observed that, even in the simplest of cases, such as an utterance of (1): ‘He is a stockbroker’, a speaker's audience might misunderstand her utterance even if they correctly identify the referent of the relevant singular term, and understand what is being predicated of it. Numerous theorists, including Bezuidenhout [1997], Heck [1995], Paul [1999], and Récanati [1993, 1995], have used Loar's observation to argue against direct reference accounts of assertoric content and communication, maintaining that, even in (...) these simple cases, the propositional contribution of a referring expression must be more than just its referent. -/- I argue here that, while Loar's observation is correct, the conclusion he and others have sought to draw from it simply does not follow. Rather, his observation helps to remind us of an important Gricean insight into the nature of communicative acts—including acts of speaker-reference—namely, that there is more to understanding a communicative act than merely entertaining what a speaker is intending to communicate thereby. Once we remember this insight, we see that the phenomenon to which Loar is calling our attention should actually be expected given the direct reference theorist's assumptions, together with independently plausible Gricean principles concerning how we make our referential intentions manifest in communication. More generally, the Gricean strategy for explaining the challenge posed by Loar cases suggests a novel way to account for certain crucial anti-direct reference intuitions—one requiring no modification of the original theory (e.g., no invocation of ‘descriptive enrichments’ as in Soames [2002]), thereby allowing for a direct reference account of what is asserted in utterances of ‘simple sentences’ such as (1).

It makes sense that the more information people share, the better they communicate. To evaluate the effect of knowledge overlap on the effectiveness of communication, participants played a communication game where the “director” identified objects to the “addressee”. Pairs either shared information about most objects' names (high overlap), or about the minority of objects' names (low overlap). We found that high-overlap directors tended to use more names than low overlap directors. High overlap directors also used more names with (...) objects whose names only they knew, thereby confusing their addressees more often than low-overlap directors. We conclude that while sharing more knowledge can be beneficial to communication overall, it can cause communication to be locally ineffective. Sharing more information reduces communication effectiveness precisely when there is an opportunity to inform—when people communicate information only they themselves know. (shrink)
