Although Michael Yong-Set's proposal to approach argumentation theory from a ludological perspective is not yet sufficiently developed to warrant adopting it, there is enough to warrant exploring it further – which is all the reception it needs at this point.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Transformations of the Confucian Way, and: Histoire de la pensáe chinoiseMichael NylanTransformations of the Confucian Way. By John H. Berthrong. Boulder, Colorado: Westview Press, 1998. Pp. xiv + 250.Histoire de la pensáe chinoise. By Anne Cheng. Paris: Editions du Seuil, 1997. Pp. 650.Reviewing bad books, W. H. Auden once observed, is bad for the character. On the assumption that the reverse must also be true, I am delighted (...) to review not one, but two good books: John H. Berthrong's Transformations of the Confucian Way and Anne Cheng's Histoire de la pensáe chinoise. Each contributes significantly—though differently—to our appreciation of the long history of classical learning in China. [End Page 632]Berthrong, in seven chapters and 250 pages, neatly summarizes the main developments of what he calls the "Confucian Way." As a teaching tool for undergraduates and nonspecialists, the book's strong appeal is based on three factors: (1) the coherence of its narrative (no mean feat for a book covering over 2,500 years of the Way); (2) the respectful approach that it brings to intellectual traditions and the controversies they have engendered over time; and (3) the case that it urges for the relevance of the Confucian Way today to life outside the classroom and outside China. To achieve such coherence, Berthrong divides his story into seven manageable units spanned by "six paradigmatic historical transformations of the Confucian Tradition" (p. 6): (1) the rise of the Confucian tradition in Zhou China; (2) the canonization of the Confucian Classics in Han times; (3) "the defense of the [Confucian] faith" during the third through the tenth centuries; (4) the Neo-Confucian Revival in the Song; (5) reactions to Song Neo-Confucianism in "the turn toward the mind," epitomized by Wang Yangming (1472-1529); (6) the late empires of Qing China, Tokugawa Japan, and Yi/Chosŏn Korea; and (7) Confucianism in the modern world.Berthrong has chosen a sensible approach to his sprawling history, whose scope would leave most scholars cowering. He judiciously draws upon the best scholarship available on each of the transformations (giving full credit where it is due), with the result that even beginning students can quickly gain a sense not only of the important debates in the long history of classical learning but also of prominent scholars working in the field today. As a master of the declarative sentence, Berthrong has no trouble writing the bridging paragraphs required to situate his thinkers neatly within the broader historical trends that Confucian morality has shaped, reflected, or been changed by. His afterword devoted to "Further Readings and Contentious Issues" then leads readers responsibly outside the book to larger worlds, broaching difficult topics with sensibility and grace. Without hesitation, then, I would recommend that this book be assigned in all manner of undergraduate courses, in "rice paddies" as well as in courses on comparative thought and Chinese history— though I would have my own students think of it as an intellectual history of East Asia, not as a history of the Confucian Way (a point to which I return below).To communicate his respect, Berthrong seeks to illustrate "the complexity of the vision, life, conduct, meditation, conflict, compromise, and creativity that is hidden by the generalization of the word 'Confucianism'" (p. 7). To Berthrong's way of thinking, the death of "scriptural Confucianism" (Mark Elvin's phrase) notwithstanding, a tradition so protean in its transformations and so compelling in its advocacy of full humanity (ren) should find a way to renew itself in the near future—especially when his set of thinkers have at least as much light to shed on the philosophical problems encountered by humans as their counterparts among the philosophical masters of Europe and America. Berthrong is therefore at his very best when discussing xing (human nature), li (principle), and xin (heart/mind), comparing and contrasting the epistemology of Shao Yong (1011-1077), the cosmological speculations of Zhou Dunyi (1017-1073), the Cheng brothers on mind and principle (li), or the ruminations on sagehood by Wang Yangming (1472-1529).While such discussions richly convey to even the beginning student of Chinese [End Page 633] thought...

Many believe that the ethical problems of donation after cardiocirculatory death (DCD) have been "worked out" and that it is unclear why DCD should be resisted. In this paper we will argue that DCD donors may not yet be dead, and therefore that organ donation during DCD may violate the dead donor rule. We first present a description of the process of DCD and the standard ethical rationale for the practice. We then present our concerns with DCD, including the following: (...) irreversibility of absent circulation has not occurred and the many attempts to claim it has have all failed; conflicts of interest at all steps in the DCD process, including the decision to withdraw life support before DCD, are simply unavoidable; potentially harmful premortem interventions to preserve organ utility are not justifiable, even with the help of the principle of double effect; claims that DCD conforms with the intent of the law and current accepted medical standards are misleading and inaccurate; and consensus statements by respected medical groups do not change these arguments due to their low quality including being plagued by conflict of interest. Moreover, some arguments in favor of DCD, while likely true, are "straw-man arguments," such as the great benefit of organ donation. The truth is that honesty and trustworthiness require that we face these problems instead of avoiding them. We believe that DCD is not ethically allowable because it abandons the dead donor rule, has unavoidable conflicts of interests, and implements premortem interventions which can hasten death. These important points have not been, but need to be fully disclosed to the public and incorporated into fully informed consent. These are tall orders, and require open public debate. Until this debate occurs, we call for a moratorium on the practice of DCD. (shrink)

Recently, a number of philosophers of biology have endorsed views about random drift that, we will argue, rest on an implicit assumption that the meaning of concepts such as drift can be understood through an examination of the mathematical models in which drift appears. They also seem to implicitly assume that ontological questions about the causality of terms appearing in the models can be gleaned from the models alone. We will question these general assumptions by showing how the same equation (...) — the simple 2 = p2 + 2pq + q2 — can be given radically different interpretations, one of which is a physical, causal process and one of which is not. This shows that mathematical models on their own yield neither interpretations nor ontological conclusions. Instead, we argue that these issues can only be resolved by considering the phenomena that the models were originally designed to represent and the phenomena to which the models are currently applied. When one does take those factors into account, starting with the motivation for Sewall Wright’s and R.A. Fisher’s early drift models and ending with contemporary applications, a very different picture of the concept of drift emerges. On this view, drift is a term for a set of physical processes, namely, indiscriminate sampling processes. (shrink)

Moral particularists are united in their opposition to the codification of morality, and their work poses an important challenge to traditional ways of thinking about moral philosophy. Defenders of moral particularism have, with near unanimity, sought support from a doctrine they call “holism in the theory of reasons.” We argue that this is all a mistake. There are two ways in which holism in the theory of reasons can be understood, but neither provides any support for moral particularism. Moral particularists (...) are united in their opposition to the codification of morality in purely descriptive terms, but their opposition takes different forms. Sometimes particularists maintain that codifying the moral landscape is impossible. In other contexts particularists argue that moral principles are in any event unnecessary. In yet other contexts particularists contend that the codification of morality is undesirable, perhaps because it would encourage people to look less carefully at the case at hand.1 These are distinct theses, although particularists often endorse all three. As Jonathan Dancy, citing John McDowell puts it, “Particularism is at its crudest the claim that we neither need nor can see the search for an ‘evaluative outlook which one can endorse as rational as the search for a set of principles.’”2 On any interpretation, particularism poses an important challenge for traditional conceptions of moral philosophy..

Airway mucin secretion is important pathophysiologically and as a model of polarized epithelial regulated exocytosis. We find the trafficking protein, SNAP23, selectively expressed in secretory cells compared with ciliated and basal cells of airway epithelium by immunohistochemistry and FACS, suggesting that SNAP23 functions in regulated but not constitutive epithelial secretion. Heterozygous SNAP23 deletant mutant mice show spontaneous accumulation of intracellular mucin, indicating a defect in baseline secretion. However mucins are released from perfused tracheas of mutant and wild-type mice at the (...) same rate, suggesting that increased intracellular stores balance reduced release efficiency to yield a fully compensated baseline steady state. In contrast, acute stimulated release of intracellular mucin from mutant mice is impaired whether measured by a static imaging assay 5 min after exposure to the secretagogue ATP or by kinetic analysis of mucins released from perfused tracheas during the first 10 min of ATP exposure. Together, these data indicate that increased intracellular stores cannot fully compensate for the defect in release efficiency during intense stimulation. The lungs of mutant mice develop normally and clear bacteria and instilled polystyrene beads comparable to WT mice, consistent with these functions depending on baseline secretion that is fully compensated.

Infectious disease outbreaks in residential care are complex to manage and difficult to control. Research in this setting that includes individuals who lack capacity must conform to national legislation. We report here on our study that is investigating outbreaks of scabies, an itchy skin infection, in the residential care setting in the southeast of England. There appears to be a gap in legislative advice regarding the inclusion of people who lack capacity in research that takes place during time-limited acute scenarios (...) such as outbreaks. We received inconsistent advice from experts regarding, in particular, the role of nominated consultees. There is a potential inequality for vulnerable populations who cannot themselves provide informed consent in terms of their access to participation in a range of health-related research. (shrink)

Michael Potter presents a comprehensive new philosophical introduction to set theory. Anyone wishing to work on the logical foundations of mathematics must understand set theory, which lies at its heart. Potter offers a thorough account of cardinal and ordinal arithmetic, and the various axiom candidates. He discusses in detail the project of set-theoretic reduction, which aims to interpret the rest of mathematics in terms of set theory. The key question here is how to deal with the paradoxes that bedevil (...) set theory. Potter offers a strikingly simple version of the most widely accepted response to the paradoxes, which classifies sets by means of a hierarchy of levels. What makes the book unique is that it interweaves a careful presentation of the technical material with a penetrating philosophical critique. Potter does not merely expound the theory dogmatically but at every stage discusses in detail the reasons that can be offered for believing it to be true. Set Theory and its Philosophy is a key text for philosophy, mathematical logic, and computer science. (shrink)

This article sets the stage for the essays in this issue of Perichoresis on the Trinitarianism of the Particular Baptists in the British Isles and Ireland between the 1640s and 1840s. It argues that this Trinitarianism is part of a larger debate about the Trinity that has been greatly forgotten in the scholarly history of this doctrine. It also touches on the way that Baptist theologians like John Gill were critical to the preservation of Trinitarian witness among this Christian community.

This paper defends Mereological Universalism(the thesis that, for any set S of disjoint objects, there is an object that the members of S compose. Universalism is unpalatable to many philosophers because it entails that if there are such things as my left tennis shoe, W. V. Quine, and the Taj Mahal, then there is another object that those three things compose. This paper presents and criticizes Peter van Inwagen's argument against Universalism and then presents a new argument in favor of (...) Universalism. It turns out that the most reasonable way to resist the argument for Universalism is to deny the existence of artifacts; thus, if we believe in artifacts, we have no real choice other than to embrace Universalism.

We introduce the set of definable restricted complex powers for expansions of the real field and calculate it explicitly for expansions of the real field itself by collections of restricted complex powers. We apply this computation to establish a classification theorem for expansions of the real field by families of locally closed trajectories of linear vector fields.

In Morality and Global Justice, Michael Boylan presents us with a set of solutions to some of the world’s most pressing moral issues. Boylan claims that his solutions are not utopian; instead, they are practical, workable policy recommendations that governments and other organizations should adopt. For the most part, Boylan is correct; there are no obviously insurmountable obstacles to implementing many of his recommendations. But, as he himself admits, his position on immigrants and refugees borders on the utopian (Boylan (...) 2011, 204). In what follows, I will discuss two concerns that I have about his position. The first concern (1) is consequentialist: I fear that implementing a policy of open borders may lead to economic, environmental, and political consequences that are on balance undesirable. The second (2) is practical: even if American citizens have moral reasons for supporting a policy of open borders, they may have reasons of self-interest for rejecting it. If this is correct, then Boylan may have a difficult time garnering the support necessary to make the policy a reality. (shrink)

This article provides current Schwartz Values Survey (SVS) data from samples of business managers and professionals across 50 societies that are culturally and socioeconomically diverse. We report the society scores for SVS values dimensions for both individual- and societal-level analyses. At the individual-level, we report on the ten circumplex values sub-dimensions and two sets of values dimensions (collectivism and individualism; openness to change, conservation, self-enhancement, and self-transcendence). At the societal-level, we report on the values dimensions of embeddedness, hierarchy, mastery, affective (...) autonomy, intellectual autonomy, egalitarianism, and harmony. For each society, we report the Cronbach’s α statistics for each values dimension scale to assess their internal consistency (reliability) as well as report interrater agreement (IRA) analyses to assess the acceptability of using aggregated individual level values scores to represent country values. We also examined whether societal development level is related to systematic variation in the measurement and importance of values. Thus, the contributions of our evaluation of the SVS values dimensions are two-fold. First, we identify the SVS dimensions that have cross-culturally internally reliable structures and within-society agreement for business professionals. Second, we report the society cultural values scores developed from the twenty-first century data that can be used as macro-level predictors in multilevel and single-level international business research.

In this paper, we offer a Piagetian perspective on the construction of the logico-mathematical schemas which embody our knowledge of logic and mathematics. Logico-mathematical entities are tied to the subject's activities, yet are so constructed by reflective abstraction that they result from sensorimotor experience only via the construction of intermediate schemas of increasing abstraction. The axiom set does not exhaust the cognitive structure (schema network) which the mathematician thus acquires. We thus view truth not as something to be defined within (...) the closed world of a formal system but rather in terms of the schema network within which the formal system is embedded. We differ from Piaget in that we see mathematical knowledge as based on social processes of mutual verification which provide an external drive to any necessary dynamic of reflective abstraction within the individual. From this perspective, we argue that axiom schemas tied to a preferred interpretation may provide a necessary intermediate stage of reflective abstraction en route to acquisition of the ability to use formal systems in abstracto.

We employ techniques related to Lempp and Lerman's “iterated trees of strategies” to directly measure a Σ5-predicate and use this in showing the index set of the cuppable r.e. sets to be Σ5-complete. We also show how certain technical devices arise naturally out of the iterated-trees context, in particular, links arise as manifestations of a generalized notion of “stage”.

Three experiments investigated the processing of the implicature associated with some using a “gumball paradigm.” On each trial, participants saw an image of a gumball machine with an upper chamber with 13 gumballs and an empty lower chamber. Gumballs then dropped to the lower chamber and participants evaluated statements, such as “You got some of the gumballs.” Experiment 1 established that some is less natural for reference to small sets and unpartitioned sets compared to intermediate sets. Partitive some of was (...) less natural than simple some when used with the unpartitioned set. In Experiment 2, including exact number descriptions lowered naturalness ratings for some with small sets but not for intermediate size sets and the unpartitioned set. In Experiment 3, the naturalness ratings from Experiment 2 predicted response times. The results are interpreted as evidence for a Constraint-Based account of scalar implicature processing and against both two-stage, Literal-First models and pragmatic Default models. (shrink)

Ethical decision making measures are widely applied as the principal dependent variable used in studies of research integrity. However, evidence bearing on the internal and external validity of these measures is not available. In this study, ethical decision making measures were administered to 102 graduate students in the biological, health, and social sciences, along with measures examining exposure to ethical breaches and the severity of punishments recommended. The ethical decision making measure was found to be related to exposure to ethical (...) events and the severity of punishments awarded. The implications of these findings for the application of ethical decision making measures are discussed. (shrink)

Here, we argue for a mathematical equation that captures desert. Our procedure consists of setting out principles that a correct equation must satisfy and then arguing that our set of equations satisfies them. We then consider two objections to the equation. First, an objector might argue that desert and well-being separately contribute to intrinsic goodness, and they do not separately contribute. The concern here is that our equations treat them as separate contributors. Second, our set of desert-equations are unlike equations (...) in science because our equations involve multiple desert-equations with the applicable equation depending on how the variables are filled out. Neither objection succeeds. (shrink)

There is, on the face of it, a logical difficulty as well as a practical one about ascribing to parents both a right to give their children a religious upbringing and a duty to avoid indoctrinating them. Curiously, this logical difficulty was largely overlooked in the debate on religious upbringing and parental rights between Terence McLaughlin, Eamonn Callan and Peter Gardner in the 1980s. In this paper I set out the terms of the logical problem and propose a solution to (...) it. (shrink)

This paper aims to provide a theoretical framework for explaining the subjective character of pain experience in terms of what we will call ‘embodied predictive processing’. The predictive processing (PP) theory is a family of views that take perception, action, emotion and cognition to all work together in the service of prediction error minimisation. In this paper we propose an embodied perspective on the PP theory we call the ‘embodied predictive processing (EPP) theory. The EPP theory proposes to explain pain (...) in terms of processes distributed across the whole body. The prediction error minimising system that generates pain experience comprises the immune system, the endocrine system, and the autonomic system in continuous causal interaction with pathways spread across the whole neural axis. We will argue that these systems function in a coordinated and coherent manner as a single complex adaptive system to maintain homeostasis. This system, which we refer to as the neural-endocrine-immune (NEI) system, maintains homeostasis through the process of prediction error minimisation. We go on to propose a view of the NEI ensemble as a multiscale nesting of Markov blankets that integrates the smallest scale of the cell to the largest scale of the embodied person in pain. We set out to show how the EPP theory can make sense of how pain experience could be neurobiologically constituted. We take it to be a constraint on the adequacy of a scientific explanation of subjectivity of pain experience that it makes it intelligible how pain can simultaneously be a local sensing of the body, and, at the same time, a more global, all-encompassing attitude towards the environment. Our aim in what follows is to show how the EPP theory can meet this constraint. (shrink)

Working memory--the ability to keep important information in mind while comprehending, thinking, and acting--varies considerably from person to person and changes dramatically during each person's life. Understanding such individual and developmental differences is crucial because working memory is a major contributor to general intellectual functioning. This volume offers a state-of-the-art, integrative, and comprehensive approach to understanding variation in working memory by presenting explicit, detailed comparisons of the leading theories. It incorporates views from the different research groups that operate on each (...) side of the Atlantic, and covers working-memory research on a wide variety of populations, including healthy adults, children with and without learning difficulties, older adults, and adults and children with neurological disorders. A particular strength of this volume is that each research group explicitly addresses the same set of theoretical questions, from the perspective of both their own theoretical and experimental work and from the perspective of relevant alternative approaches. Through these questions, each research group considers their overarching theory of working memory, specifies the critical sources of working memory variation according to their theory, reflects on the compatibility of their approach with other approaches, and assesses their contribution to general working memory theory. This shared focus across chapters unifies the volume and highlights the similarities and differences among the various theories. Each chapter includes both a summary of research positions and a detailed discussion of each position. Variation in Working Memory achieves coherence across its chapters, while presenting the entire range of current theoretical and experimental approaches to variation in working memory. (shrink)

Integrating large language models (LLMs) like GPT-4 into medical ethics is a novel concept, and understanding the effectiveness of these models in aiding ethicists with decision-making can have significant implications for the healthcare sector. Thus, the objective of this study was to evaluate the performance of GPT-4 in responding to complex medical ethical vignettes and to gauge its utility and limitations for aiding medical ethicists. Using a mixed-methods, cross-sectional survey approach, a panel of six ethicists assessed LLM-generated responses to eight (...) ethical vignettes.The main outcomes measured were relevance, reasoning, depth, technical and non-technical clarity, as well as acceptability of GPT-4’s responses. The readability of the responses was also assessed. Of the six metrics evaluating the effectiveness of GPT-4’s responses, the overall mean score was 4.1/5. GPT-4 was rated highest in providing technical (4.7/5) and non-technical clarity (4.4/5), whereas the lowest rated metrics were depth (3.8/5) and acceptability (3.8/5). There was poor-to-moderate inter-rater reliability characterised by an intraclass coefficient of 0.54 (95% CI: 0.30 to 0.71). Based on panellist feedback, GPT-4 was able to identify and articulate key ethical issues but struggled to appreciate the nuanced aspects of ethical dilemmas and misapplied certain moral principles.This study reveals limitations in the ability of GPT-4 to appreciate the depth and nuanced acceptability of real-world ethical dilemmas, particularly those that require a thorough understanding of relational complexities and context-specific values. Ongoing evaluation of LLM capabilities within medical ethics remains paramount, and further refinement is needed before it can be used effectively in clinical settings. (shrink)

While the rise of a ‘dictatorship of relativism’ was a longstanding concern for Joseph Ratzinger/Pope Benedict XVI, some commentators have suggested that—for better or for worse—the challenge posed by relativism appears to be less of a priority for Pope Francis. Indeed, Francis's remark, ‘Who am I to judge?’ appears to have become as much the defining soundbite for his papacy as the ‘dictatorship of relativism’ was for Benedict's. Contrary to these perceptions, this article argues that a critique of relativism is (...) in fact a central aspect of Pope Francis's magisterium. Francis exhibits continuity with Benedict by amplifying his concerns about the danger of attempting to reconstruct reality according to human desire, but Francis also develops his predecessor's teaching by introducing the category of ‘practical relativism’. With this development, relativism cannot be dismissed as a theoretical problem that only plagues those who refuse to assent to the truth intellectually. The willingness to set aside the truth to which one assents when it proves inconvenient represents a more pernicious—precisely because more subtle—form of relativism that Francis argues must be rooted out, not by argument, but through self‐examination and the practice of solidarity.

In recent years, language has been shown to play a number of important cognitive roles over and above the communication of thoughts. One hypothesis gaining support is that language facilitates thought about abstract categories, such as democracy or prediction. To test this proposal, a novel set of semantic memory task trials, designed for assessing abstract thought non-linguistically, were normed for levels of abstractness. The trials were rated as more or less abstract to the degree that answering them required the participant (...) to abstract away from both perceptual features and common setting associations corresponding to the target image. The normed materials were then used with a population of people with aphasia to assess the relationship of abstract thought to language. While the language-impaired group with aphasia showed lower overall accuracy and longer response times than controls in general, of special note is that their response times were significantly longer as a function of a trial’s degree of abstractness. Further, the aphasia group’s response times in reporting their degree of confidence (a separate, metacognitive measure) were negatively correlated with their language production abilities, with lower language scores predicting longer metacognitive response times. These results provide some support for the hypothesis that language is an important aid to abstract thought and to metacognition about abstract thought. (shrink)

In Wyoming Revisited, Michael A. Amundson uses the power of rephotography to show how landscapes across the state have endured over the last century. Three sets of photographs—the original black-and-white photographs taken by famed Wyoming photographer Joseph E. Stimson more than a century ago, repeat black-and-white images taken by Amundson in the 1980s, and a third view in color taken by the author in 2007–2008—are accompanied by captions explaining the history and importance of each site as well as information (...) on the process of repeat photographic fieldwork. The 117 locations feature street views of Wyoming towns and cities, as well as views from the state's famous natural landmarks like Yellowstone National Park, Grand Teton National Park, Devil's Tower National Monument, Hot Springs State Park, and Big Horn and Shoshone National Forests. In addition, Amundson provides six in-depth essays that explore the life of Joseph E. Stimson, the rephotographic process and how it has evolved, and how repeat photography can be used to understand history, landscape, historic preservation, and globalization. Wyoming Revisited highlights the historic evolution of the American West over the past century and showcases the significant changes that have occurred over the past twenty-five years. This book will appeal to photographers, historians of the American West, and anyone interested in Wyoming's history or landscape. The publication of this book is supported in part by the Wyoming Cultural Trust Fund. (shrink)

Ethics consultation services provide support to staff, patients, and family members who find themselves in morally difficult situations in healthcare settings. Not unlike other clinical consultation services, ethics consultation activities should be well documented. Good documentation allows for evaluation of the consultation process and the ability to refer back to consults when needed, and provides data for future research in healthcare ethics (HCE).In our exploration of existing HCE documentation systems, we identified two main points of interest. First, HCE information documentation (...) systems are powerful tools for providing information on ethics consultation services. These documentation systems can be used to produce detailed reports on various HCE activities both institutionally and cross-institutionally. Second, our findings indicate greater agreement in the language and terminology of HCE needs to be established. Cultivation of such common language is needed in order to develop a standard healthcare ethicists can use to document and categorize consults. Standardization of language would allow data to be readily comparable and lead to more consistency in documentation of ethics consultations. Ultimately, standardization of documentation can also constitute a standard of practice for HCE in general. The development of such standards is essential for any developing profession, and will be required for HCE as it moves in towards professionalization in Canada. (shrink)

Coherence is the property of propositions hanging or fitting together. Intuitively, adding a proposition to a set of propositions should be compatible with either increasing or decreasing the set’s degree of coherence. In this paper we show that probabilistic coherence measures based on relative overlap are in conflict with this intuitive verdict. More precisely, we prove that according to the naive overlap measure it is impossible to increase a set’s degree of coherence by adding propositions and that according to the (...) refined overlap measure no set’s degree of coherence exceeds the degree of coherence of its maximally coherent subset. We also show that this result carries over to all other subset-sensitive refinements of the naive overlap measure. As both results stand in sharp contrast to elementary coherence intuitions, we conclude that extant relative overlap measures of coherence are inadequate. (shrink)

Physicians are taught that the foundation of the physician-patient relationship is trust, and trust is based in part on truthfulness. While drawing important Òlines in the sandÓ regarding whether and why to tell the truth, ethics codes promulgating honesty fail to provide clinicians with guidance regarding what is the truth, as well as when and how to disclose it. These issues may be at the core of why an adverse event is left undisclosed. Consistently being truthful in the setting of (...) an error is particularly difficult and requires overcoming a number of institutional and personal barriers. The article concludes that if delivering Òthe truthÓ is important, then articulation of criteria for determining what should be told, by whom, and when is essential. A policy that considers the practical issues and provides guidance may be useful. (shrink)

It is illegitimate to read any ontology about "race" off of biological theory or data. Indeed, the technical meaning of "genetic variation" is fluid, and there is no single theoretical agreed-upon criterion for defining and distinguishing populations (or groups or clusters) given a particular set of genetic variation data. Thus, by analyzing three formal senses of "genetic variation"—diversity, differentiation, and heterozygosity—we argue that the use of biological theory for making epistemic claims about "race" can only seem plausible when it relies (...) on the user’s own assumptions about race; the move from biological measures to claims about “race” inevitably amounts to a pernicious reification. We also excavate assumptions in the history of the technical discourse over the concept of "race" (e.g., Livingstone's and Dobzhansky's 1962 exchange, Edwards' 2003 response to Lewontin 1972, as well as contemporary discussions of cladistic "race", and "races" as clusters). We show that claims about the existence (or non-existence) of "race" are underdetermined by biological facts, methods, and theories. Biological theory does not force the concept of "race" upon us; our social discourse, social ontology, and social expectations do. We become prisoners of our abstractions at our own hands, and at our own expense. (shrink)

Relative overlap measures of coherence have recently been shown to have two devastating properties: according to the plain relative overlap measure, the degree of coherence of any set of propositions cannot be increased by adding further propositions, and according to the refined relative overlap measure, no set can be more coherent than its most coherent two-element subset. This result has been taken to rule out relative overlap as a foundation for a probabilistic explication of coherence. The present paper shows that (...) this view is premature: we propose a relative overlap measure that does not fall victim to the two properties. The guiding idea is to employ a well-established recipe for the construction of coherence measures and to adapt it to the idea of relative overlap. We show that this new measure keeps up with, or even outperforms, former overlap measures in a set of desiderata for coherence measures and a collection of popular test cases. This result re-establishes relative overlap as a candidate for a proper formalization of coherence. (shrink)

Smith begins by noting the isomorphism between the rational transition to a psychological state from others and the derivation of a concluding proposition from premises in the deductive theoretical realm, and he argues that this isomorphism led Hume to think that the rationality of the psychological transition is to be explained by the deductive validity of the derivation. Generalizing, Smith argues, Hume concluded that the concept of a reason—that is, the concept of a consideration that justifies—must be prior to and (...) explain the concept of rationality. The fact that there is no such isomorphism in the practical and inductive realms is therefore, Smith suggests, what led Hume to his inductive and practical skepticism. Pace Hume, however, Smith argues that we need not agree that the concept of a reason is prior to the concept of rationality: we have an independent idea of the coherence of a set of psychological states and this is sufficient to provide us with an account of what it is for beliefs and desires to be justified. But it remains an open question whether the Kantians are right that practical coherence can be extended as far as yielding justified desires to do as morality bids. (shrink)

Ethical consumption is on the rise, however little is known about the degree and the implications of the sometime conflicting sets of values held by the broad category of consumers who report consuming ethically. This paper explores convergence and divergence of ethical consumption values through a study of organic, fair trade, and local food consumers in Colorado. Using survey and focus group results, we first examine demographic and attitudinal correlates of ethical consumption. We then report evidence that while many organic, (...) fair trade, and local food consumers converge around similar values, some Colorado consumers support only local food, while opposing the consumption of organic and fair trade products. Next, we investigate how ethical consumers who converge and diverge frame their commitment to consuming ethically. The discussion and conclusion suggest that community development planners of projects that focus on ethical consumption will need to successfully traverse issues stemming from convergence and divergence to enjoy long-term sustained success.

A logical explanation of consciousness has been known for decades. The brain must construct a specific set of information about conscious feeling, causing people to believe, think, and claim to have consciousness. Theories that propose an actual, intangible feeling are non-explanatory. They add a magical red herring while leaving unexplained the objective phenomena: the believing, thinking, and claiming.

For cognitive scientists in general, schemas are the appropriate functional units; brain theorists can work with neural layers as units intermediate between structures subserving schemas and small neural circuits.After an account of different levels of analysis, we describe visuomotor coordination in terms of perceptual schemas and motor schemas. The interest of schemas to cognitive science in general is illustrated with the example of perceptual schemas in (...) high-level vision and motor schemas in the control of dextrous hands.Rana computatrix, the computational frog, is introduced to show how one constructs an evolving set of model families to mediate flexible cooperation between theory and experiment. Rana computatrix may be able to do for the study of the organizational principles of neural circuitry what Aplysia has done for the study of subcellular mechanisms of learning. Approach, avoidance, and detour behavior in frogs and toads are analyzed in terms of interacting schemas. Facilitation and prey recognition are implemented as tectal-pretectal interactions, with the tectum modeled by an array of tectal columns. We show how layered neural computation enters into models of stereopsis and how depth schemas may involve the interaction of accommodation and binocular cues in anurans. (shrink)

Many parents cite intimacy as one of their reasons for deciding to educate at home. It seems intuitively obvious that home education is conducive to intimacy because of the increased time families spend together. Yet what is not clear is whether intimacy can provide justification for one’s decision to home educate. To see whether this is so, we introduce the concept of ‘attentive parenting’, which encompasses a set of family characteristics, and we examine whether and under what conditions attentive parents (...) risk loss of intimacy by sending their children to school; or, alternatively, whether they can avoid this risk by educating children at home. What we will determine is whether families who exhibit the specified characteristics are prima facie justified in educating their children at home under the conditions of interest. We argue that, for attentive parents, home education not only promotes greater intimacy, but also provides insurance against the loss of intimacy that may occur under certain conditions when children attend schools.

Public education is not just a way to organise and fund education. It is also the expression of a particular ideal about education and of a particular way to conceive of the relationship between education and society. The ideal of public education sees education as an important dimension of the common good and as an important institution in securing the common good. The common good is never what individuals or particular groups want or desire, but always reaches beyond such particular (...) desires towards that which societies as a whole should consider as desirable. This does, of course, put the common good in tension with the desires of individuals and groups. Neo-liberal modes of governance have, over the past decades, put this particular educational set up under pressure and have, according to some, eroded the very idea of the common good. This set of contributions reflects on this state of affairs, partly through an exploration of the idea of publicness itself – how it can be rearticulated and regained – and partly through reflections on the current state of education in the ‘north’ and the ‘south.’.

In this paper the familiar construction of the category of coalgebras for a cartesian comonad is extended to the setting of “algebraic set theory”. In particular, it is shown that, under suitable assumptions, several kinds of categories of classes are stable under the formation of coalgebras for a cartesian comonad, internal presheaves and comma categories.

Karl Jaspers' phenomenology remains important today, not solely because of its continuing influence in some areas of psychiatry, but because, if fully understood, it can provide a method and set of concepts for making new progress in the science of psychopathology. In order to understand this method and set of concepts, it helps to recognize the significant influence that Edmund Husserl's early work, Logical investigations, exercised on Jaspers' formulation of them. We trace the Husserlian influence while clarifying the main components (...) of Jaspers' method. Jaspers adopted Husserl's notions of intuition, description, and presuppositionlessness, transforming them when necessary in order to serve the investigations of the psychopathologist. Jaspers also took over from Wilhelm Dilthey and others the tools of understanding (Verstehen) and self-transposal. The Diltheyian procedures were integrated into the Husserlian ones to produce a method that enables psychiatrists to define the basic kinds of psychopathological mental states. (shrink)

This paper argues against minimalism about truth. It does so by way of a comparison of the theory of truth with the theory of sets, and consideration of where paradoxes may arise in each. The paper proceeds by asking two seemingly unrelated questions. First, what is the theory of truth about? Answering this question shows that minimalism bears important similarities to naive set theory. Second, why is there no strengthened version of Russell's paradox, as there is a strengthened Liar paradox? (...) Answering this question shows that like naive set theory, minimalism is unable to make adequate progress in resolving the paradoxes, and must be replaced by a drastically different sort of theory. Such a theory, it is shown, must be fundamentally non-minimalist. (shrink)

This is a description of an avian-shaped feature that rests below a network of cellular structures found on a mound within the Argyre Basin of Mars in Mars Global Surveyor image M14-02185, acquired on April 30, 2000, and released to the public on April 4, 2001. The area examined is located near 48.0° South, 55.1° West. The formation is approximately 2,400 meters long from the tip of its beak to the tip of its farthest tail feather. There is a minimum (...) of six different variations in appearance of the surface material over this small area. Utilizing the public targeting request form provided on the Mars Global Surveyor (MGS) website, co-author Miller secured a second image of the area that was obtained on July 3, 2006, showing this feature under different conditions S20-00165. The new image was then released to the public on August 11, 2006. A third image of the formation identified as MGS S13-01480 was acquired on December 15, 2005, and although officially processed on June 20, 2006, it was not made available to the public until August 22, 2009, on NASA’s Planetary Data System (PDS) website. All three of the MGS images reveal defining aspects of this avian feature, including a head, beak, body, eye, leg, foot, toes, wing, and feathers. When taken together, these components induce the visual impression of an avian-shaped formation that exhibits a unique set of proportional features. Adjoining this formation is a composite of complex cellular features that form a compartmentalized infrastructure. The three authors who are veterinarians provide a critical analysis of the avian features, and the geologist and geoscientist authors examine natural mechanisms that could contribute to the formation of this feature. An extensive search of comparable regions within and beyond the area of the Argyre Basin was conducted. A list of these sites is provided, and terrestrial comparisons are also offered. (shrink)

We say that a computably enumerable (c. e.) degree a is plus-cupping, if for every c.e. degree x with $0 < x \leq a$ , there is a c. e. degree $y \not= 0'$ such that $x \vee y = 0/\'$ . We say that a is n-plus-cupping. if for every c. e. degree x, if $0 < x \leq a$ , then there is a $low_n$ c. e. degree 1 such that $x \vee l = 0'$ . Let PC (...) and $PC_n$ be the set of all plus-cupping, and n-plus-cupping c. e. degrees respectively. Then $PC_{1} \subseteq PC_{2} \subseteq PC_3 = PC$ . In this paper we show that $PC_{1} \subset PC_2$ , so giving a nontrivial hierarchy for the plus cupping degrees. The theorem also extends the result of Li, Wu and Zhang [14] showing that $LC_{1} \subset LC_2$ , as well as extending the Harrington plus-cupping theorem [8]. (shrink)

Since the introduction of the concept of brain death by the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death in 1968, the validity of this concept has been challenged by medical scientists, as well as by legal, philosophical, and religious scholars. In light of increased criticism of the concept of brain death, Stephen Napier, a staff ethicist at the National Catholic Bioethics Center, set out to prove that the whole-brain death criterion serves as (...) good evidence for death in the Catholic bioethical framework, on the grounds that when whole-brain death has occurred the soul has already departed from the body. Opponents have argued that (1) brain death does not disrupt the somatic integrative unity and coordinated biological functioning of a living organism and (2) clinical tests outlined in the practice guidelines for determining brain death lack sufficient power to exclude persisting function and fail to detect elements of the brain that, although currently functionless, may retain potential for recovery under conditions of optimal medical care. It is therefore possible that heart-beating organ procurement from patients with impaired consciousness is de facto a concealed practice of active euthanasia and physician-assisted death, both of which, either concealed or overt, the Catholic Church opposes.
