This paper contributes to the mathematical foundations of the model for utility theory developed by Richard Jeffrey in The Logic of Decision [5]. In it I discuss the relationship of Jeffrey's to classical models, state and interpret an existence theorem for numerical utilities and subjective probabilities and restate a theorem on their uniqueness.

In this paper I discuss some of the mathematics behind an often quoted existence theorem from Richard Jeffrey's The Logic of Decision (Jeffrey 1990) in order to pose several new questions about the meaning and value of that mathematics for decision theory.

The aim of this book is to help students write mathematics better. Throughout it are large exercise sets well-integrated with the text and varying appropriately from easy to hard. Basic issues are treated, and attention is given to small issues like not placing a mathematical symbol directly after a punctuation mark. And it provides many examples of what students should think and what they should write and how these two are often not the same.

For nearly as long as the topic of sustainable business has been taught and researched in business schools, proponents have warned about barriers to genuine integration in business school practices. This article examines how academic sustainability centres try to overcome barriers to integration by achieving technical, cultural and political fit with their environment :67–92; Ansari et al., Academy of Management Review 35:67–92, 2010). Based on survey and interview data, we theorise that technical, cultural and political fit are intricately related, and (...) that these interrelations involve legitimacy, resources and collaboration effects. Our findings about sustainability centres offer novel insights on integrating sustainable business education given the interrelated nature of different types of fit and misfit. We further contribute to the literature on fit by highlighting that incompatibility between strategies to achieve different types of fit may act as a source of dynamism. (shrink)

The education of students and professionals in business ethics is an increasingly important goal on the agenda of business schools and corporations. The present study provides a meta-analysis of 25 previously conducted business ethics instructional programs. The role of criteria, study design, participant characteristics, quality of instruction, instructional content, instructional program characteristics, and characteristics of instructional methods as moderators of the effectiveness of business ethics instruction were examined. Overall, results indicate that business ethics instructional programs have a minimal␣impact on increasing (...) outcomes related to ethical perceptions, behavior, or awareness. However, specific criteria, content, and methodological moderators of effectiveness shed light on potential recommendations for␣improving business ethics instruction. Implications for␣future research and practice in business ethics are discussed. (shrink)

Differences across fields and experience levels are frequently considered in discussions of ethical decision making and ethical behavior. In the present study, doctoral students in the health, biological, and social sciences completed measures of ethical decision making. The effects of field and level of experience with respect to ethical decision making, metacognitive reasoning strategies, social-behavioral responses, and exposure to unethical events were examined. Social and biological scientists performed better than health scientists with respect to ethical decision making. Furthermore, the ethical (...) decision making of health science students decreased as experience increased. Moreover, these effects appeared to be linked to the specific strategies underlying participants' ethical decision making. The implications of these findings for ethical decision making are discussed. (shrink)

Scholars have proposed a number of courses and programs intended to improve the ethical behavior of scientists in an attempt to maintain the integrity of the scientific enterprise. In the present study, we conducted a quantitative meta-analysis based on 26 previous ethics program evaluation efforts, and the results showed that the overall effectiveness of ethics instruction was modest. The effects of ethics instruction, however, were related to a number of instructional program factors, such as course content and delivery methods, in (...) addition to factors of the evaluation study itself, such as the field of investigator and criterion measure utilized. An examination of the characteristics contributing to the relative effectiveness of instructional programs revealed that more successful programs were conducted as seminars separate from the standard curricula rather than being embedded in existing courses. Furthermore, more successful programs were case based and interactive, and they allowed participants to learn and practice the application of real-world ethical decision-making skills. The implications of these findings for future course development and evaluation are discussed. (shrink)

In recent years, we have seen a new concern with ethics training for research and development professionals. Although ethics training has become more common, the effectiveness of the training being provided is open to question. In the present effort, a new ethics training course was developed that stresses the importance of the strategies people apply to make sense of ethical problems. The effectiveness of this training was assessed in a sample of 59 doctoral students working in the biological and social (...) sciences using a pre-post design with follow-up and a series of ethical decision-making measures serving as the outcome variable. Results showed not only that this training led to sizable gains in ethical decision making but also that these gains were maintained over time. The implications of these findings for ethics training in the sciences are discussed. (shrink)

What is the role of language in social interaction? What does language bring to social encounters? We argue that language can be conceived of as a tool for interacting minds, enabling especially effective and flexible forms of social coordination, perspective-taking and joint action. In a review of evidence from a broad range of disciplines, we pursue elaborations of the language-as-a-tool metaphor, exploring four ways in which language is employed in facilitation of social interaction. We argue that language dramatically extends the (...) possibility-space for interaction, facilitates the profiling and navigation of joint attentional scenes, enables the sharing of situation models and action plans, and mediates the cultural shaping of interacting minds.

An implicit goal of many interventions intended to enhance integrity is to minimize peoples' exposure to unethical events. The intent of the present effort was to examine if exposure to unethical practices in the course of one's work is related to ethical decision making. Accordingly, 248 doctoral students in the biological, health, and social sciences were asked to complete a field appropriate measure of ethical decision making. In addition, they were asked to complete measures examining the perceived acceptability of unethical (...) events and a measure examining perceptions of ethical climate. When these criterion measures were correlated with a measure examining the frequency with which they had been exposed to unethical events in their day-to-day work, it was found that event exposure was strongly related to ethical decision making but less strongly related to climate perceptions and perceptions of event acceptability. However, these relationships were moderated by level of experience. The implications of these findings for practices intended to improve ethics are discussed. (shrink)

In the United States, approximately 2.53 million people sustain a concussion each year. Relative to adults, youth show greater cognitive deficits following concussion and a longer recovery. An accurate and reliable imaging method is needed to determine injury severity and symptom resolution. The primary objective of this study was to characterize concussions with diffusion tensor imaging. This was performed through a normative Z-scoring analysis of DTI metrics, fractional anisotropy, axial diffusivity, and radial diffusivity, to quantify patient-specific injuries and identify commonly (...) damaged brain regions in paediatric concussion patients relative to healthy controls. It was hypothesized that personalizing the detection analysis through normative Z-scoring would provide an understanding of trauma-induced microstructural damage. Concussion patients were volunteers recruited from the Emergency Department of the McMaster Children’s Hospital with a recent concussion, 9 males and 17 females, mean age 14.22 ± 2.64, while healthy paediatric brain DTI datasets were obtained from an MRI data repository. Significant abnormalities were commonly found in the longitudinal fasciculus, fronto-occipital fasciculus, and corticospinal tract, while unique abnormalities were localized in a number of other areas reflecting the individuality of each child’s injury. Total injury burden, determined by the number of regions containing outliers per DTI metric per patient, was used as the metric to quantify the overall injury severity of each patient. The primary outcome of this analysis found that younger patients experienced a significantly greater injury burden when measured using fractional anisotropy. These results show that DTI was able to detect microstructural changes caused by concussion, on a per-person basis, and has the potential to be a useful tool for improving diagnostic accuracy and prognosis of a concussion.

Which function is computed by a Turing machine will depend on how the symbols it manipulates are interpreted. Further, by invoking bizarre systems of notation it is easy to define Turing machines that compute textbook examples of uncomputable functions, such as the solution to the decision problem for first-order logic. Thus, the distinction between computable and uncomputable functions depends on the system of notation used. This raises the question: which systems of notation are the relevant ones for determining whether a (...) function is computable? These are the acceptable notations. I argue for a use criterion of acceptability: the acceptable notations for a domain of objects D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document} are the notations that we can use for the usual D\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal {D}}$$\end{document}-activities. Acceptable notations for natural numbers are ones that we can count with. Acceptable notations for logical formulas are the ones that we can use in inference and logical analysis. And so on. This criterion makes computability a relative notion—whether a function is computable depends on which notations are acceptable, which is relative to our interests and abilities. I argue that this is not a problem, however, since there is independent reason for taking the extension of computable function to be relative to contingent facts. Similarly, the fact that the use criterion makes a mathematical distinction depend on practical concerns is also not a problem because it dovetails with similar phenomena in other areas of computability theory, namely the roles of notation in computation over real numbers and of Extended Church’s Thesis in complexity theory.

Integrity is a critical determinant of the effectiveness of research organizations in terms of producing high quality research and educating the new generation of scientists. A number of responsible conduct of research (RCR) training programs have been developed to address this growing organizational concern. However, in spite of a significant body of research in ethics training, it is still unknown which approach has the highest potential to enhance researchers’ integrity. One of the approaches showing some promise in improving researchers’ integrity (...) has focused on the development of ethical decision-making skills. The current effort proposes a novel curriculum that focuses on broad metacognitive reasoning strategies researchers use when making sense of day-to-day social and professional practices that have ethical implications for the physical sciences and engineering. This sensemaking training has been implemented in a professional sample of scientists conducting research in electrical engineering, atmospheric and computer sciences at a large multi-cultural, multi-disciplinary, and multi-university research center. A pre-post design was used to assess training effectiveness using scenario-based ethical decision-making measures. The training resulted in enhanced ethical decision-making of researchers in relation to four ethical conduct areas, namely data management, study conduct, professional practices, and business practices. In addition, sensemaking training led to researchers’ preference for decisions involving the application of the broad metacognitive reasoning strategies. Individual trainee and training characteristics were used to explain the study findings. Broad implications of the findings for ethics training development, implementation, and evaluation in the sciences are discussed. (shrink)

In spite of the wide variety of approaches to ethics training it is still debatable which approach has the highest potential to enhance professionals’ integrity. The current effort assesses a novel curriculum that focuses on metacognitive reasoning strategies researchers use when making sense of day-to-day professional practices that have ethical implications. The evaluated trainings effectiveness was assessed by examining five key sensemaking processes, such as framing, emotion regulation, forecasting, self-reflection, and information integration that experts and novices apply in ethical decision-making. (...) Mental models of trained and untrained graduate students, as well as faculty, working in the field of physical sciences were compared using a think-aloud protocol 6 months following the ethics training. Evaluation and comparison of the mental models of participants provided further validation evidence for sensemaking training. Specifically, it was found that trained students applied metacognitive reasoning strategies learned during training in their ethical decision-making that resulted in complex mental models focused on the objective assessment of the situation. Mental models of faculty and untrained students were externally-driven with a heavy focus on autobiographical processes. The study shows that sensemaking training has a potential to induce shifts in researchers’ mental models by making them more cognitively complex via the use of metacognitive reasoning strategies. Furthermore, field experts may benefit from sensemaking training to improve their ethical decision-making framework in highly complex, novel, and ambiguous situations. (shrink)

Moral leadership matters. As world politics enters a new and dangerous era, judgment, constancy, moral purpose, and a willingness to overcome partisan politicking are essential for America's leaders. Tempered Strength finds the alternative standard of leadership that Americans are seeking in the classical philosophy of prudence. Ethan Fishman's new work brings together leading American political scientists—including Ronald Beiner, Kenneth L. Deutsch, and George Anastaplo—to discuss the evolution of a standard of prudential leadership both reasonable in nature and practical in (...) scope. Section One studies the meaning of prudence and its evolution in the history of political science from Aristotelian phronesis to Xenophon, Thomas Aquinas, Edmund Burke, and Michael Oakeshott. Section Two demonstrates how the theory of prudential leadership can be applied to practical political issues. (shrink)

Standard semantic theories predict that non-deictic readings for complex demonstratives should be much more widely available than they in fact are. If such readings are the result of a lexical ambiguity, as Kaplan (in: Almog, Perry, Wettstein (eds) Themes from Kaplan, Oxford University Press, Oxford, 1977) and others suggest, we should expect them to be available wherever a definite description can be used. The same prediction follows from ‘hidden argument’ theories like the ones described by King (Complex Demonstratives: a Quantificational (...) Account, MIT Press, Cambridge, 2001) and Elbourne (Situations and Individuals, MIT Press, Cambridge, 2005). Wolter (That’s That; the Semantics and Pragmatics of Demonstrative Noun Phrases. Ph.D. thesis, University of California at Santa Cruz, 2006), however, has shown that complex demonstratives admit non-deictic interpretations only when a precise set of structural constrains are met. In this paper, I argue that Wolter’s results, properly understood, upend the philosophical status quo. They fatally undermine the ambiguity theory and demand a fundamental rethinking of the hidden argument approach. (shrink)

In this paper I argue, that if it is metaphysically possible for it to have been the case that nothing existed, then it follows that the right modal logic cannot extend D, ruling out popular modal logics S4 and S5. I provisionally defend the claim that it is possible for nothing to have existed. I then consider the various ways of resisting the conclusion that the right modal logic is weaker than D.

Comparative Political Theory and Cross-Cultural Philosophy explores new forms of philosophizing in the age of globalization by challenging the conventional border between the East and the West, as well as the traditional boundaries among different academic disciplines.

This collection of essays argues that any valid theory of the modern should—indeed must—reckon with the medieval. Offering a much-needed correction to theorists such as Hans Blumenberg, who in his _Legitimacy of the Modern Age_ describes the “modern age” as a complete departure from the Middle Ages, these essays forcefully show that thinkers from Adorno to Žižek have repeatedly drawn from medieval sources to theorize modernity. To forget the medieval, or to discount its continued effect on contemporary thought, is to (...) neglect the responsibilities of periodization. In _The Legitimacy of the Middle Ages_, modernists and medievalists, as well as scholars specializing in eighteenth-, nineteenth-, and twentieth-century comparative literature, offer a new history of theory and philosophy through essays on secularization and periodization, Marx’s theory of commodity fetishism, Heidegger’s scholasticism, and Adorno’s nominalist aesthetics. One essay illustrates the workings of medieval mysticism in the writing of Freud’s most famous patient, Daniel Paul Schreber, author of _Memoirs of My Nervous Illness_. Another looks at Michael Hardt and Antonio Negri’s _Empire_, a theoretical synthesis whose conscientious medievalism was the subject of much polemic in the post-9/11 era, a time in which premodernity itself was perceived as a threat to western values. The collection concludes with an afterword by Fredric Jameson, a theorist of postmodernism who has engaged with the medieval throughout his career. _Contributors_: Charles D. Blanton, Andrew Cole, Kathleen Davis, Michael Hardt, Bruce Holsinger, Fredric Jameson, Ethan Knapp, Erin Labbie, Jed Rasula, D. Vance Smith, Michael Uebel. (shrink)

Much has been written on whether practical knowledge (knowledge-how) reduces to propositional knowledge (knowledge-that). Less attention has been paid to what we call deliberative knowledge (knowledge-to), i.e., knowledge ascriptions embedding other infinitival questions, like _where to meet_, _when to leave_, and _what to bring_. We offer an analysis of knowledge-to and argue on its basis that, regardless of whether knowledge-how reduces to knowledge-that, no such reduction of knowledge-to is forthcoming. Knowledge-to, unlike knowledge-that and knowledge-how, requires the agent to have formed (...) certain conditional intentions. We discuss the philosophical implications for knowledge-how, deliberative questions, and virtue. (shrink)

Between 1945 and 1953, while the Soviet Union confronted postwar reconstruction and Cold War crises, its unchallenged leader Joseph Stalin carved out time to study scientific disputes and dictate academic solutions. He spearheaded a discussion of "scientific" Marxist-Leninist philosophy, edited reports on genetics and physiology, adjudicated controversies about modern physics, and wrote essays on linguistics and political economy. Historians have been tempted to dismiss all this as the megalomaniacal ravings of a dying dictator. But in Stalin and the Soviet Science (...) Wars, Ethan Pollock draws on thousands of previously unexplored archival documents to demonstrate that Stalin was in fact determined to show how scientific truth and Party doctrine reinforced one another. Socialism was supposed to be scientific, and science ideologically correct, and Stalin ostensibly embodied the perfect symbiosis between power and knowledge. Focusing on six major postwar debates in the Soviet scientific community, this elegantly written book shows that Stalin's forays into scholarship can be understood only within the context of international tensions, institutional conflicts, and the growing uncertainty about the proper relationship between scientific knowledge and Party-dictated truths. The nature of Stalin's interventions makes clear that more was at stake than high politics: these science wars were about asserting that the Party was rational and modern, and about codifying the Soviet worldview in a battle for the hearts and minds of people around the globe during the early Cold War. Ultimately, however, the effort to develop a scientific basis for Soviet ideology undermined the system's legitimacy. (shrink)

In the last two decades, there has been a blossoming literature aiming to counter the neglect of plant capacities. In their recent paper, Miguel Segundo-Ortin and Paco Calvo begin by providing an overview of the literature to then question the mistaken assumptions that led to plants being immediately rejected as candidates for sentience. However, it appears that many responses to their arguments are based on the implicit conviction that because animals have far more sophisticated cognition and agency than plants, and (...) that plants should not have the same moral status as animals, plants should not have any moral status. Put in simpler terms: it is not as bad to eat plants than to eat, say, pigs. While there are still uncertainties around comparative moral and policy implications between animals and plants, given a gradualist account of quasi-sentience and partial moral status, both of which we claim are a matter of degree, we may not have to abolish our convictions by declaring that plants have no sentience or moral status at all. Indeed, we can hold two things at the same time: that animals and plants have moral status, but animals have prima facie more moral status than plants. (shrink)

I present unexplored and unaccounted for uses of 'wants'. I call them advisory uses, on which information inaccessible to the desirer herself helps determine what she wants. I show that extant theories by Stalnaker, Heim, and Levinson fail to predict these uses. They also fail to predict true indicative conditionals with 'wants' in the consequent. These problems are related: intuitively valid reasoning with modus ponens on the basis of the conditionals in question results in unembedded advisory uses. I consider two (...) fixes, and end up endorsing a relativist semantics, according to which desire attributions express information-neutral propositions. On this view, 'wants' functions as a precisification of 'ought', which exhibits similar unembedded and compositional behavior. I conclude by sketching a pragmatic account of the purpose of desire attributions that explains why it made sense for them to evolve in this way. (shrink)

The practical criteria by which developmental biologists choose their model systems have evolutionary correlates. The result is a sample that is not merely small, but biased in particular ways, for example towards species with rapid, highly canalized development. These biases influence both data collection and interpretation, and our views of how development works and which aspects of it are important.

Evolutionary developmental biologists categorize many different kinds of things, from ontogenetic stages to modules of gene activity. The process of categorization—the establishment of “kinds”—is an implicit part of describing the natural world in consistent, useful ways, and has an essentially practical rather than philosophical basis. Kinds commonly serve one of three purposes: they may function (1) as practical tools for communication; (2) to support prediction and generalization; or (3) as a basis for theoretical discussions. Beyond the minimal requirement that classifications (...) reflect biological reality, what sorts of kinds or classification will be useful in advancing a research program depends on the epistemological context. Thus, the important meaning of “natural” in “natural kinds” is not “natural with respect to nature,” but “natural with respect to the question.” This conclusion arises from the recognition that the proper role of concepts (e.g. natural kind, module, homology, model) is not to answer biological questions, but rather to help frame them. From a scientist’s perspective, arguing about the wording (or existence) of a single definition of “natural” or “kind” is beside the point: we get more work done by letting the question at hand determine what kinds of kinds are natural, on the basis of their ability to help answer it. We should be content to let “natural kinds” remain vague, multivalent, and–therefore broadly useful. For a philosopher like Hacking, the diverse, disparate, and ultimately incommensurable uses of the term “natural kind” have diluted its value so far that it loses all meaning. For practicing scientists, however, defining useful kinds in the context of particular questions and systems remains a productive epistemological strategy. (shrink)

Conceptual engineering is a philosophical method that aims to design and spread conceptual and linguistic devices to cause meaningful changes in the world. So far, however, conceptual engineers have struggled to successfully spread the conceptual and linguistic entities they have designed to their target communities. This paper argues that conceptual engineering is far more likely to succeed if it incorporates empirical data and empirical methods. Because the causal factors influencing successful propagation of linguistic or conceptual devices are as complicated and (...) interwoven as they are, proper empirical research will greatly boost the likelihood that propagation is successful. In arguing for the superiority of empirical conceptual engineering over armchair-based conceptual engineering, this paper proposes a framework for understanding the causal forces at play in propagation. This is a three-part framework between the label of a lexical item, the psychological states associated with the lexical item, and the worldly things associated with the lexical item. By understanding the way causal forces affecting propagation play out at these three levels, conceptual engineers can better conceptualize, study, and harness the different causal forces affecting the success of their conceptual engineering projects.

Conceptual engineering is the practice of revising concepts to improve how people talk and think. Its ability to improve talk and thought ultimately hinges on the successful dissemination of desired conceptual changes. Unfortunately, the field has been slow to develop methods to directly test what barriers stand in the way of propagation and what methods will most effectively propagate desired conceptual change. In order to test such questions, this paper introduces the masked time-lagged method. The masked time-lagged method tests people's (...) conceptual understanding at two different points in time without their knowledge of being tested, allowing us to measure conceptual revision in action. Using a masked time-lagged design on a content internalist framework, we attempted to revise PLANET and DINOSAUR in online participants to match experts' concepts. We successfully revised PLANET but not DINOSAUR, demonstrating some of the difficulties conceptual engineers face. Nonetheless, this paper provides conceptual engineers, regardless of framework, with the tools to tackle questions related to implementation empirically and head-on. (shrink)

Leading animal models are powerful tools for translational research, but they also present obstacles. Poorly conducted preclinical research in animals is a common cause of translational failure, but even when such research is well-designed and carefully executed, challenges remain. In particular, dominant models may bias research directions, elide essential aspects of human disease, omit important context, or subtly shift research targets. Recognizing these stumbling blocks can help us find ways to avoid them: employing a wider range of models, incorporating more (...) realistic environmental conditions, better aligning studies between animals and patients, and focusing on human biology and therapeutic goals. Such changes are costly; but insisting it would be impractical or unrealistic to change strategies offers no way out of the current impasse. Rather, we must acknowledge the obstacles as well as the advantages presented by core models, and direct some of our investments in translational research toward getting around them. The dominance of biomedical research by a handful of animal models introduces subtle but significant obstacles to translation. Recognizing these obstacles is a critical first step toward finding ways around them; this paper describes how dominant models can create roadblocks, and suggests strategies to improve the efficiency of translation from animal models to humans.

In this paper, I argue that the ‘social meanings’ associated with sociolinguistic variation put pressure on the standard philosophical conception of language, according to which the foremost thing we do with words is exchange information. Drawing on parallels with the explanatory challenge posed by slurs and pejoratives, I argue that the best way to understand social meanings is to think of them in speech act theoretic terms. I develop a distinctive form of pluralism about the performances realized by means of (...) sociolinguistic variants, and I claim that engagement with such performances is an utterly pervasive feature of our linguistic activity.

Recently, philosophers have offered compelling reasons to think that demonstratives are best represented as variables, sensitive not to the context of utterance, but to a variable assignment. Variablists typically explain familiar intuitions about demonstratives—intuitions that suggest that what is said by way of a demonstrative sentence varies systematically over contexts—by claiming that contexts initialize a particular assignment of values to variables. I argue that we do not need to link context and the assignment parameter in this way, and that we (...) would do better not to. (shrink)

The Knower paradox purports to place surprising a priori limitations on what we can know. According to orthodoxy, it shows that we need to abandon one of three plausible and widely-held ideas: that knowledge is factive, that we can know that knowledge is factive, and that we can use logical/mathematical reasoning to extend our knowledge via very weak single-premise closure principles. I argue that classical logic, not any of these epistemic principles, is the culprit. I develop a consistent theory validating (...) all these principles by combining Hartry Field's theory of truth with a modal enrichment developed for a different purpose by Michael Caie. The only casualty is classical logic: the theory avoids paradox by using a weaker-than-classical K3 logic. I then assess the philosophical merits of this approach. I argue that, unlike the traditional semantic paradoxes involving extensional notions like truth, its plausibility depends on the way in which sentences are referred to--whether in natural languages via direct sentential reference, or in mathematical theories via indirect sentential reference by Gödel coding. In particular, I argue that from the perspective of natural language, my non-classical treatment of knowledge as a predicate is plausible, while from the perspective of mathematical theories, its plausibility depends on unresolved questions about the limits of our idealized deductive capacities.

The current work examines how cues traditionally used to signal environmental friendliness, specifically the color green and eco-labels, and influence product efficacy perceptions and subsequent purchase intentions. Across three experiments, we find that environmental cues used in isolation reduce perceptions of product efficacy.

We discuss the implications of our findings for research (...) on environmental consumption as well as offer insight into the effective use of environmental cues on product packaging. (shrink)

This book argues that the philosophical history of India contains a tradition of skepticism about philosophy represented most clearly by three figures: Nāgārjuna, Jayarāśi, and Śrī Harṣa.

The beginning of the COVID-19 pandemic offers a unique case study for understanding conceptual and linguistic propagation. In early 2020, scientists, politicians, journalists, and other public figures had to, with great urgency, propagate several public health-related concepts and terms to every person they could. This paper examines the propagation of coronavirus and social distancing and develops a framework for understanding how the language used to express a notion can help or hinder propagation. I argue that anyone designing a representational device (...) for propagation needs to appreciate the three-way causal relationship between language, people’s mental representations, and the extramental world. Using this framework, I explore what makes “social distancing” a bad name for social distancing and why it is unproblematic that “coronavirus” is a scientifically loose way of speaking about the virus. Through this and further study of the many historical examples of linguistic and conceptual propagation, conceptual engineers can better understand the complex challenges facing people who want to propagate representational devices.

While most philosophers will likely agree that this decline is lamentable, the question of what exactly is lost with a language has not been systematically explored in the philosophical literature. In this paper, I address this lacuna by arguing that language loss constitutes a problematic form of illocutionary silencing. When a language disappears, past and present speakers lose the ability to realize a range of speech (...) acts that can only be realized in that language. With that ability, speakers lose something in which they have a fundamental interest: their standing as fully empowered members of a linguistic community. (shrink)

Standard semantic theories predict that non-deictic readings for complex demonstratives should be much more widely available than they in fact are. If such readings are the result of a lexical ambiguity, as Kaplan (1977) and others suggest, we should expect them to be available wherever a definite description can be used. The same prediction follows from ‘hidden argument’ theories like the ones described by King (2001) and Elbourne (2005). Wolter (2006), however, has shown that complex demonstratives admit non-deictic interpretations only (...) when a precise set of structural constrains are met. In this paper, I argue that Wolter’s results, properly understood, upend the philosophical status quo. They fatally undermine the ambiguity theory and demand a fundamental rethinking of the hidden argument approach. (shrink)

Despite its status at the heart of a closely related field, philosophers have so far mostly overlooked a phenomenon sociolinguists call ‘social meaning’. My aim in this paper will be to show that by properly acknowledging the significance of social meanings, we can identify an important new set of forms that discursive injustice takes. I begin by surveying some data from variationist sociolinguistics that reveal how subtle differences in the way a particular content is expressed allow us to perform importantly (...) different illocutionary actions, actions we use to do things like constructing a public persona and building a rapport with an audience. The social importance of these activities and the pervasiveness of our engagement in them means that the ethical stakes involved are high—substantial injustices may result if speakers from different social groups are differently empowered with regard to the illocutionary possibilities made available to them by variation.
