As part of an extended participant observation study of hospice, I present in this article some reflections on my first experiences as a hospice volunteer. Discussion of these experiences emphasizes the influences of my own socialization, but suggests the types of filters trough which people often see and behave in the world of the dying and beyond.

This book includes ten essays that trace the notion of unconcealment as it develops from Heidegger's early writings to his later work, shaping his philosophy of truth, language and history. 'Unconcealment' is the idea that what entities are depends on the conditions that allow them to manifest themselves. This concept, central to Heidegger's work, also applies to worlds in a dual sense: first, a condition of entities manifesting themselves is the existence of a world; and second, worlds themselves are disclosed. (...) The unconcealment or disclosure of a world is the most important historical event, and Heidegger believes there have been a number of quite distinct worlds that have emerged and disappeared in history. Heidegger's thought as a whole can profitably be seen as working out the implications of the original understanding of unconcealment. (shrink)

Huston Smith has argued that the universal source of wholeness, which he refers to as the primordial tradition, is essential to a meaningful life. Indeed embracing this tradition is, said Smith, an act of rejoining the human race. Our current forms of organized religion offer us ritualized expressions of this tradition, yet often fail to provide us with transpersonal growth; it is this transpersonal growth that reconnects us with the source of religion. This essay differentiates mainstream religion from a way (...) that we can begin to construct a physical theory of the primordial tradition–a necessary first step toward reclaiming the source of religion.

This article is an extended commentary inspired by Alan Drengson's paper “Shifting Paradigms: From Technocrat to Planetary Person” (Drengson 2011). In this article Susan Greenwood and I echo Drengson's criticism that Euro-American science is incomplete, having committed what Thomas Roberts calls “The Singlestate Fallacy: the erroneous assumption that all worthwhile abilities reside in our normal, awake mindbody state” (Roberts 2006:105). This singlestate fallacy is vividly portrayed in Mary Shelley's novel Frankenstein, whose critique of Euro-American science is revisited in this article. (...) Alternatively, Greenwood and I suggest that what is needed is a multimodel framework “that allows for in-depth analysis of the different modes of consciousness.” Roberts refers to this alternative attitude toward science as the Multistate Paradigm. An awareness of the transformational character of shamanism is also explored in this article as a means to overcome the oppositions between the technocratic and person planetary perspective, and their related gender associations.

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (...) (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called “perceiving the present,” that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity. (shrink)

The ancient Pyrrhonians skeptics suspended judgment about all philosophical views. Their main opponents were the Dogmatists—those who believed their preferred philosophical views. In Outlines of Skeptical-Dogmatism: On Disbelieving Our Philosophical Views, Mark Walker argues, contra Pyrrhonians and Dogmatists, for a "darker" skepticism: we should disbelieve our philosophical views. On the question of political morality, for example, we should disbelieve libertarianism, conservativism, socialism, liberalism, and any alternative ideologies. Since most humans have beliefs about philosophical subject matter, such as beliefs about (...) religious and political matters, humanity writ large should disbelieve their preferred philosophical views. Walker argues that Skeptical-Dogmatism permits a more realistic estimation of our epistemic powers. Dogmatists who believe their view is correct, while believing that two or more competitor views of their opponents are false, must—at least implicitly—take themselves to be “über epistemic superiors” to their disagreeing colleagues. Such a self-assessment is as implausible as it is hubristic. Skeptical-Dogmatism, in contrast, permits a more realistic and humbler epistemic self-conception. The author also shows that there are no insuperable practical difficulties in living as a Skeptical-Dogmatist. (shrink)

Normal systems of modal logic, interpreted as deontic logics, are unsuitable for a logic of conflicting obligations. By using modal operators based on a more complex semantics, however, we can provide for conflicting obligations, as in [9], which is formally similar to a fragment of the logic of ability later given in [2], Having gone that far, we may find it desirable to be able to express and consider claims about the comparative strengths, or degrees of urgency, of the conflicting (...) obligations under which we stand. This paper, building on the formalism of the logic of ability in [2], provides a complete and decidable system for such a language. (shrink)

This paper describes and defends the view that minimal chemical life essentially involves the chemical integration of three chemical functionalities: containment, metabolism, and program (Rasmussen et al. in Protocells: bridging nonliving and living matter, 2009a ). This view is illustrated and explained with the help of CMP and Rasmussen diagrams (Rasmussen et al. In: Rasmussen et al. (eds.) in Protocells: bridging nonliving and living matter, 71–100, 2009b ), both of which represent the key chemical functional dependencies among containment, metabolism, and (...) program. The CMP model of minimal chemical life gains some support from the broad view of life as open-ended evolution, which I have defended elsewhere (Bedau in The philosophy of artificial life, 1996 ; Bedau in Artificial Life, 4:125–140, 1998 ). Further support comes from the natural way the CMP model resolves the puzzle about whether life is a matter of degree. (shrink)

Weak emergence is the view that a system’s macro properties can be explained by its micro properties but only in an especially complicated way. This paper explains a version of weak emergence based on the notion of explanatory incompressibility and “crawling the causal web.” Then it examines three reasons why weak emergence might be thought to be just in the mind. The first reason is based on contrasting mere epistemological emergence with a form of ontological emergence that involves irreducible downward (...) causation. The second reason is based on the idea that attributions of emergence are always a reflection of our ignorance of non-emergent explanations. The third reason is based on the charge that complex explanations are anthropocentric. Rather than being just in the mind, weak emergence is seen to involve a distinctive kind of complex, macro-pattern in the mind-independent objective micro-causal structure that exists in nature. The paper ends by addressing two further questions. One concerns whether weak emergence applies only or mainly to computer simulations and computational systems. The other concerns the respect in which weak emergence is dynamic rather than static. (shrink)

But in spite of its serious flaws, both in concept and in practice, genetic-specific legislation is sometimes worth passing anyway—sometimes a bad idea is reasonable.

In 2018, the remarkable rescue of twelve young boys and their football coach trapped in a flooded cave in Thailand captured worldwide attention. The rescue required the boys to be dived out of the cave system while fully anaesthetized which presented unique practical and ethical challenges for the rescue team. Major departures from normal anaesthetic practice were required. Taking anaesthetized children underwater was unprecedented, complex, and dangerous. To do this underground in a flooded cave meant the risks were extreme. Using (...) a principlist approach, this essay will outline the rescue plan highlighting the ethical dilemmas faced by the rescue team. Informed consent and full disclosure of information are justifiably waived in emergency disaster scenarios. Beneficence as a guiding principle becomes a major challenge when all rescue options appear destined to cause likely fatalities of healthy young boys. Importantly, virtues and virtue ethics also have a vital role to play when confronting and dealing with ethical challenges in disaster scenarios—this will be discussed with particular reference to the cave rescue.

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.2 (2003) 61-72 [Access article in PDF] From Personal to Social Transaction:A Model of Aesthetic Reading in the Classroom Mark A. Pike This article seeks to define more precisely the nature of the individual transaction that occurs between reader and text and the potential for aesthetic reading in literature classrooms by relating knowledge of the way pupils engage in literary transactions to theoretical (...) perspectives that address the issue. The validity of Louise Rosenblatt's transactional theory of the literary work, expounded in Literature as Exploration and The Reader, The Text, The Poem, and its relevance for contemporary educators, particularly in the field of English education, has recently been reasserted by Jeanne Connell in her timely and cogent article in this journal. 1 The present article, however, seeks to refocus debate by problematizing and subsequently developing some aspects of key theories such as Rosenblatt's while examining the individual and social nature of reading in schools. Rosenblatt's view that aesthetic experiences can have both social origin and effect certainly deserves further theorizing if aesthetic experience in school communities and classrooms is to flourish.The influence of John Dewey's Art as Experience upon Rosenblatt is evident as this seminal text conceives of our primary task as the restoration of "continuity between the refined and intensified forms of experience that are works of art and everyday events." 2 Such continuity with experience is vital because, for Dewey, "experience is the fulfillment of an organism in its struggles and achievements in a world of things, it is art in germ." 3 Applying such a notion to education in schools, Rosenblatt saw the aim of literature lessons as the growth of experience rather than the acquisition of knowledge. Yet, despite such progress, in the United Kingdom, teachers of English are in the unenviable position of having to deliver an extensive body of knowledge prescribed by the National Curriculum and also to focus explicitly upon the features of certain types of text as they teach the National Literacy Strategy. 4 In Rosenblatt's work the emphasis on our experience of [End Page 61] literary works provides a much needed alternative to positions such as that adopted by New Criticism where "it is never what a poem says which matters, but what it is" because we acknowledge we can only ever gain access to what a poem says as "the sentence that seems to need no interpretation is already the product of one." 5 Clearly, understanding the reader's transaction with texts is where we must begin if we wish to foster aesthetic reading in our classrooms.Transactional theory also appears to be closely related to Martin Heidegger's thought in Being and Time where Dasein (givenness, existence, being) is seen as a distinctive characteristic of the human being as our consciousness projects things of the world and is also subjected to the things of the world which belong to us, in some sense, only as long as our consciousness is projecting them. 6 The validity of Dewey's view, where experience is not separated from art, can be seen when we acknowledge that we can "never adopt an attitude of detached contemplation, looking down on the world as if from a mountain top" for we are "inevitably merged with the very object of our consciousness." 7Such a view reflects Hans-Georg Gadamer's position in Truth and Method in which Heidegger's explanation of situation is applied to literary theory because, for Gadamer, the literary work cannot appear as a packaged and completed artefact in which meaning is neatly wrapped because it is influenced by a particular reader's actions at a particular moment. 8 Rosenblatt's realistic conception that "each reading involves a particular person at a particular time and place" is developed in this article as it seems that, even now, many reader response critics and curriculum designers "write as though people read literature in a vacuum or in a generalized kind of academic setting" which often does not apply...

Prompted by the development of the Theory of Challenge and Threat States in Athletes (Jones et al, 2009), recent years has witnessed a considerable increase in research examining challenge and threat in sport. This manuscript provides a critical review of the literature examining challenge and threat in sport, tracing its historical development and some of the current empirical ambiguities. In an attempt to reconcile some of these ambiguities, and utilising neurobiological evidence associated with approach- and avoidance-motivation (cf. Elliot & Covington, (...) 2001), this paper draws upon the Evaluative Space Model (ESM: Cacioppo et al., 1997) and considers the implications for understanding challenge and threat in sport. For example, rather than see challenge and threat as opposite ends of a single bipolar continuum, the ESM implies that individuals could be (1) challenged, (2) threatened, (3) challenged and threatened, or (4) neither challenged or threatened by a particular stimulus. From this perspective it could be argued that the appraisal of some sport situations as both challenging and threatening could be advantageous, whereas the current literature seems to imply that the appraisal of stress as a threat is maladaptive for performance. In drawing upon the ESM, we outline the Evaluative Space Approach to Challenge and Threat and provide several testable hypotheses for advancing understanding of challenge and threat (in sport). We also outline a number of cardiovascular and experiential measures that can be used to examine these hypotheses. In sum, this paper provides a significant theoretical, empirical and practical contribution to our understanding of challenge and threat (in sport). (shrink)

Since the fourth century, B.C.E., the Oath of Hippocrates has been the starting point in analyzing the obligations of physicians to protect the privacy and confidentiality interests of their patients. The pertinent provision of the Oath reads as follows: “What I may see or hear in the course of the treatment or even outside of the treatment in regard to the life of men, which on no account must be spread abroad, I will keep to myself, holding such things shameful (...) to be spoken about.”This part of the Oath is subject to more than one interpretation, but its commonly accepted meaning provides the ethical foundation for the physician’s duty of confidentiality. The Oath expressly declares that a physician’s obligation of confidentiality applies beyond matters of medical care. At a time when there were no hospitals or physician offices, patients received medical care in their homes or in public places. Physicians treating patients in their homes could be expected to see and hear a wide range of activities that might be considered embarrassing, immoral, or even illegal. (shrink)

I argue that what Schelling found in fine art—the work of genius—RavaissonRavaisson-Mollien, Félix finds in habit, and from this conclude (...) that RavaissonRavaisson-Mollien, Félix offers what we might describe as a romantic conception of habit that brings it into the domain of the pre-rational, pre-reflective spontaneity that Schelling describes in artistic production.

For more than a quarter of a century, Hubert L. Dreyfus has been the leading voice in American philosophy for the continuing relevance of phenomenology, particularly as developed by Edmund Husserl, Martin Heidegger, and Maurice Merleau-Ponty. Dreyfus has influenced a generation of students and a wide range of colleagues, and these volumes are an excellent representation of the extent and depth of that influence.In keeping with Dreyfus's openness to others' ideas, many of the essays in this volume take the form (...) of arguments with various of his positions. The essays focus on the dialogue with the continental philosophical tradition, in particular the work of Heidegger, that has played a foundational role in Dreyfus's thinking. The sections are Philosophy and Authenticity; Modernity, Self, and the World; and Heideggerian Encounters. The book concludes with Dreyfus's responses to the essays.Contributors : William D.

Genetic privacy and confidentiality have both intrinsic and consequential value. Although general agreement exists about the need to protect privacy and confidentiality in the abstract, most of the concern has focused on preventing the harmful uses of this sensitive information. I hope to demonstrate in this article that the reason why genetic privacy and confidentiality are so difficult to protect is that any effort to protect them inevitably implicates broader and extremely contentious issues, such as the right of access to (...) health care. Moreover, the tentative legislative and policy steps undertaken and proposed thus far have been, for the most part, misguided, simplistic, and ineffective. (shrink)

In the post-genome world of biomedical research, an increasingly common research strategy is to focus on large repositories of biological specimens. There are now several well-known efforts to compile vast collections of biological materials, reanalyze extant samples, collect new ones, and link the samples to medical records.

Emerging companies are not only (...) compiling repositories for their own use, but some companies are positioning themselves to act as intermediaries, developing vast biobanks for sale to a wide range of other researchers.

Biobanks are repositories of human biological materials collected for biomedical research. There are over 300 million stored specimens in the United States, and the number grows by 20 million per year. In the post-genome world of high throughput gene sequencing and computational biology, biobanks hold the promise of facilitating large-scale research studies. New organizational and operational models of research repositories also raise complex issues of big science, big business, and big ethical concerns.

For centuries philosophers have wrestled with the dichotomy between individual freedom on the one hand and collective solidarity on the other. Yet today there is a growing realization that this template is fundamentally flawed. In this book, Mark Young embraces and advocates a more holistic concept of freedom; one which is not merely defined negatively but which positively provides the preconditions for individuals to actively exercise their autonomy and to flourish as human beings in the process. Young posits the (...) idea of 'freedom in community' and traces its origin back to Aristotle. Taking as his premise that humans are deeply social beings who live their lives intricately interwoven with each other, he examines what type of political community is relevant for us in this post-Classical, post-Enlightenment and, indeed, post-Existential world. Identifying the failure of traditional 'statist' models of politics, Young instead argues for a civil society: a globally interlinked and free set of liberal communities as the best context for nourishing human flourishing. In this way we can achieve a proper setting for Eudaimonia in a modern sense. (shrink)

In De Anima II.6, Aristotle divides the objects of perception into three kinds: “special perceptibles" (idia aisthêta) such as colours, sounds and flavours, which can be perceived in their own right by only one sense; “common perceptibles" (koina aisthêta) such as shapes, sizes and movements, which can be perceived in their own right by multiple senses; and “incidental perceptibles,” such as the son of Diares, which can be perceived only “incidentally” (kata sumbebêkos). In this paper, I examine this division of (...) perceptibles and consider what it amounts to. First, I argue that Aristotle’s distinction between perceiving something in its own right (kath' hauto) and perceiving it incidentally marks a causal distinction: what is perceived in its own right causes perception as such, whereas what is perceived incidentally coincides with what is perceived in its own right. Second, I argue that for Aristotle special perceptibles, unlike common perceptibles, belong to homogeneous bodies on account of their chemical composition. Finally, I explain the primacy Aristotle assigns to special perceptibles and his claim that perception of them alone is free from error. I conclude with some brief remarks on Aristotle and the primary/secondary quality distinction. (shrink)

Emerging fields of science often create new challenges for ethics and law. In assessing the broader societal implications of scientific discoveries, a reasonable analytical starting point is determining how the discoveries compare with existing science. If the new field is substantially similar to an established one, then the ethical and legal analyses are likely to be comparable. On the other hand, if the new scientific developments are extraordinary in kind or degree, then a new analytical framework and new approaches to (...) ethics and law may be necessary. (shrink)

“Unconscionable.” “Outrageous.” “Indefensible.” These are just some of the tamer descriptions for the billing practices of most hospitals, and also many physicians, that have recently come to the public's attention. Earlier this year, Time magazine published an extraordinary 24,000‐word exposé—the longest article it has ever published—detailing how even charitable hospitals routinely price‐gouge their patients.1 With characteristic flare for telling details, journalist Steven Brill documented ten‐fold markups of charges over costs at some prominent hospitals for common services like X rays and (...) lab tests, and one‐hundred‐fold mark‐ups on mundane supplies such as gauze pads and generic aspirin. Just as the buzz from Brill's article was abating, the Centers for Medicare & Medicaid Services released a comprehensive data set in May that galvanized local and national media across the country. This news tsunami caught hospital managers flat‐footed and tongue‐tied. Typical responses conceded that hospitals’ pricing practices are based neither on actual cost structures nor rational marketplace dynamics. Instead, hospitals attempted to deflect blame by noting that hardly anyone actually pays list prices, and they characterized their indefensible pricing as a symptom of a broken system that is beyond them to fix. There are two glaring faults in these standard defenses. (shrink)

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.
