In Setting Limits, Daniel Callahan advances the provocative thesis that age be a limiting factor in decisions to allocate certain kinds of health services to the elderly. However, when one looks at available data, one discovers that there are many more elderly women than there are elderly men, and these older women are poorer, more apt to live alone, and less likely to have informal social and personal supports than their male counterparts. Older women, therefore, will make the heaviest demand (...) on health care resources. If age were to become a limiting factor, as Dr. Callahan suggests it should, the limits that will be set are limits that will affect women more drastically than they affect men. This review essay examines the implications of Callahan's thesis for elderly women. (shrink)

The Philosophy of Modern Song: curious title, a curious book. If you bought it, as I did, because you are a devoted Dylan fan, hoping to find new Dylan songs inside, or at least new Dylan prose, you will be disappointed. In the photo of three musicians on the cover, none of them is Dylan. The one on the left is Little Richard. Who are the other two? Nowhere are we told their names, nor the names of the people in (...) any of the other photos, except for the sixty-six featured artists, though we will recognize many. The photo on the back cover might or might not be of the interior of Izzy Young's “Folklore Center,” reminiscent of Dylan's early days in Greenwich Village in the Sixties, when, together with my guitarist husband, I got to hear him perform after hours at the Gaslight and knew him well enough to say Hi when passing on the street.The basis for selecting the sixty-six songs anthologized and commented on is not immediately obvious. This is not a collection of Dylan's underappreciated favorites, though the taste represented is certainly eclectic and the choices are often surprising. The title does not help the reader who has not yet got her bearings... Philosophy? As if to justify his use of the word, Dylan eventually offers a lengthy comment on Albert Camus, but how relevant is that comment to these songs? And the word modern, too, means so many things—a sudden divergence from the past in the arts and literature; up-to-date and therefore good. These songs are not that kind of modern. If anything, the book looks backward, across the years of Dylan's long life to his musical awakening. Because we are almost the same age, I recognize the hodgepodge of styles and influences assembled here as belonging mostly to the early Fifties, when, like Bob, I was entering my teens by listening to, even dancing to, songs on the radio before I fell asleep at night. Enough about me! But no more apt basis for classifying these songs is suggested. They are not arranged alphabetically or chronologically.As for the anthologized songs, each one, once named, receives a commentary, and every commentary is called a chapter, and every chapter is divided into two parts, spelled out in letters as bold as a movie marquee. We are given the title of each song, the date of its release, and the name of the songwriter. The first part of each commentary consists of a paraphrase of “events” in the song, told almost exclusively in the second-person you rather than the more conventional I or the third-person he or she. Here is a passage from Dylan's paraphrase of “Blue Suede Shoes” by Carl Perkins: You get on well with most people, and you put up with a lot, and you hardly get caught off guard, but your shoes are something else. Minor things may annoy you, but you rise above them. Having your teeth kicked in, being pounded senseless, being dumped on and discredited, but you don't put any weight on that, none of it is as real to you as your shoes. They're priceless and beyond monetary worth.The paraphrase goes on for almost six pages, and to what end? The second half of each commentary, indicated by changes in the type, takes a few steps back to consider the sociological implications of the song in the context of its time. For instance, from the second half of the commentary on “Blue Suede Shoes”: “Shoes reveal character, station, and personality.” But Dylan does not use the opportunity to talk about his own character, station, personality. His associations with Carl Perkins and “Blue Suede Shoes” morph into an anecdote about a man called “Iron Felix, trusted consort to Lenin and Stalin.”A lengthy list of all required photo credits fills the two back pages but is printed in type so small it is almost illegible. If you want more information, and more importantly if you want to experience the songs discussed, your best bet is to search for the recordings on YouTube and to follow along, reading Dylan's commentary, one song at a time, while listening. Or, I hear rumors that we will need to purchase another book, the audio version of Philosophy of Modern Song, not yet released.Every song has its commentary, but nothing about this organization is stable, and as soon as the reader/listener thinks she has discovered a rationale for the order of the works selected, she is met with an exception. Basically, these seem to be songs about which Dylan has something anecdotal to say. More usefully, perhaps, they are organized around certain themes—those that have always preoccupied him: man's inhumanity to man, injustice, self-deception, the human situation. The anonymous author of the blurb on the jacket promises a master class in songwriting, but, if it exists at all, that lecture is exhausted in one or two observations, such as: “ ‘El Paso’ is built on five stanzas, each one two verses and a bridge and then returning to the next stanza.... ”It was almost fifty pages into the book that the sense of something missing overcame me. It was not only the words of the songs and the music that were missing; it was the author, the central intelligence that I love, the singer and songwriter whose name is credited on the cover but who never appears in the book, not even in a photograph. What I missed was Dylan. He had removed himself from his book's pages, except perhaps for a single instance: “You're an eighty-year old man, being wheeled around in a home for the elderly, and the nurses are getting on your nerves.... ”Has Bob Dylan grown weary of himself and all of his creations? The commentaries are not about Bob. In the whole book, the line quoted above may be the only exception. Does he refuse the “first person singular in the hopes of transcending ego”? Maybe; but we want to hear our master's voice. As for the philosophy of song? Besides the remarks on Camus, there is only one commentary in which Dylan explicitly states anything like a philosophy, and that is the one on “Willie the Wandering Gypsy and Me,” written and performed by Joe Shaver. The song has a philosophical point of view: “Keep moving, it's better, let the train keep on rolling.”. (shrink)

continent. 1.4 (2011): 286—310. This mad play of writing —Stéphane Mallarmé Somewhere in between mathematics and theory, light and dark, physicality and projection, oscillates the poetry of Alessandro De Francesco. The texts hold no periods or commas, not even a capital letter for reference. Each piece stands as an individual construction, and yet the poetry flows in and out of the frame. Images resurface from one poem to the next, haunting the reader with reincarnations of an object lost in the (...) grass or a representation of a pear in a Dutch still life, embedded in cycles of cinematic close ups and multiple dimensions. As a whole, De Francesco’s oeuvre suggests, to use the title of one of his works, a redefinition —linguistic, epistemological, personal. The poem The End (un’agenda) (The End (an agenda)) opens with a quote by literary theorist Maurice Blanchot, which may be translated as follows: Speaking is not seeing. Speaking frees thought from this optical imperative that in the Western tradition, for thousands of years, has subjugated out approach to things, and induced us to think under the guaranty of light or under the threat of its absence.[1] In writing, De Francesco seeks to redefine our approach to things. His poems, like Blanchot’s writings, speak to both illuminate and to obscure. The reader hangs in an absence of reality within language that necessitates an attempt at interpretation, yet renders such a search ultimately futile. De Francesco draws the anonymous images that appear in this poem from the city of Paris, his current home. The fragmented narrative depicts an inner doubt of realness, calling for a confirmation of a physical existence beyond verbalization and cogitation. Cyclical references to film throw into question the reliability of the reality he creates. The light, sometimes red and safe, other times absent and murky, cannot necessarily be trusted as a guaranteed means of illumination. Blanchot’s distinction between language and visualization, and the relationship of each to reality, though linked specifically to The End (un’agenda) , can be a lens through which to read any of the three works that follow. assente obliqua (absent oblique) is composed of descriptions of six still life paintings, ranging from Dutch masterpieces of the seventeenth century to 1960s minimalism. The actual images of the paintings are absent, and the text is the sole source and object of a virtual reality created around the artwork. “Absent oblique” refers to the light source placed outside of the frame, which both informs and distracts viewing of the scene. Although mere description can be unreliable and unsatisfying in its necessary limitation, the representational act of description is shown as more than just a human want. It is a need, a means by which to grapple with an unsure reality. As the illustrations progress, they descend into abstraction and chaos. The precariously placed plate triggers the movement: the bottle bursts and the objects collapse into the movement of a tracking film camera. corpo estraneo in moto ascensionale (foreign body in ascending motion) is prose poetry in action. Its objective tone of description is skewed by the subjectivity of the narrative as horrific images are relayed in fragmented but matter-of-fact manner. A “foreign body” is both a mass of cancerous cells, and a corporeal description, and the poem takes the reader on a journey back and forth between the two, destination unclear. Beyond a questioning of the real, corpo estraneo in moto ascensionale is an examination of the possible. De Francesco’s poetry becomes a camera obscura through which to observe the constant flux of light and dark that blurs our reality. His work is colored by the idea of apo koinou , a Greek term meaning “from the common” that involves a construction of two clauses with a shared word or phrase. Through such melting of meaning, De Francesco creates a fluid ambiguity that is nonetheless grounded in bodily concepts. In assente obliqua , the reader is confronted with a description of a still life that rapidly transforms into a more chilling scene: the membrane of the mushroom in the basket emerges behind the white cloth a body could hide itself that asks for help In the realm of pure description, there is a mushroom that peeks out from behind a white cloth in a basket. Behind the white cloth, too, there could be a body, hiding, asking for help. Such an elision elicits disorienting mistrust in temporality, but also expands the planar possibilities of syntactical meaning. A white cloth is not merely a construct in still life painting, but veil that both shields and reveals potential mysteries. It is a proposed alternative to a traditional Western binary of subjectivity and objectivity. The apo koinou construction is rare in modern English, having slipped out of use after its resurgence in Old English poetry. De Francesco reintroduces this blur of object and subject relations into a modern light. He draws inspiration from a device used by Gruppo 63 founder and avant-garde poet Antonio Porta tended toward repetition of phrases in third person perspective. In Italian, it is perfectly grammatically correct to omit the subject, including only a verb conjugation. Gender, even humanity unknown, the subject dissolves into the action, thus giving to the poetry the power to change the reader’s perception of who or what is actually acting. To further push the relative boundaries of experience, De Francesco expands his written poetry into what he calls “reading environments.” In these sound experiments, De Francesco’s voice reading his poetry is manipulated by real time digital voice processing. The written is transformed to the spoken, and then injected with currents of electric sound. “At each activation of word in the darkness,” (from The End (un’agenda) ) language is permutated into a nonphysical yet all-encompassing being. In these projects, realized all over Europe, De Francesco continues his examination of the word’s potency beyond the page and into an “n-dimensional space,” where the lines between nature and affect are intertwined. To publish excerpts of De Francesco’s oeuvre is to show screen shots of full-length film, to read pull quotes from a philosophy treatise. In these poems, there are questions, not to be answered, but to be questioned again. The words will oscillate in and out of the square construction found in his poems, out of the borders of the page, out of the rectangle of the laptop screen. NOTES (1) Blanchot, Maurice.

The imbalance between supply of organs for transplantation and demand for them is widening. Although the current international drive to re-establish procurement via non-heart beating organ donation/donor is founded therefore on necessity, the process may constitute a desirable outcome for patient and family when progression to brain stem death does not occur and conventional organ retrieval from the beating heart donor is thereby prevented. The literature accounts of this practice, however, raise concerns that risk jeopardising professional and public confidence in (...) the broader transplant programme. This article focuses on these clinical, ethical, and legal issues in the context of other approaches aimed at increasing donor numbers. The feasibility of introducing such an initiative will hinge on the ability to reassure patients, families, attendant staff, professional bodies, the wider public, law enforcement agencies, and the media that practitioners are working within explicit guidelines which are both ethically and legally defensible.

Is liberal democracy appropriate for East Asia? In this provocative book, Daniel Bell argues for morally legitimate alternatives to Western-style liberal democracy in the region. Beyond Liberal Democracy, which continues the author's influential earlier work, is divided into three parts that correspond to the three main hallmarks of liberal democracy--human rights, democracy, and capitalism. These features have been modified substantially during their transmission to East Asian societies that have been shaped by nonliberal practices and values. Bell points to (...) the dangers of implementing Western-style models and proposes alternative justifications and practices that may be more appropriate for East Asian societies. If human rights, democracy, and capitalism are to take root and produce beneficial outcomes in East Asia, Bell argues, they must be adjusted to contemporary East Asian political and economic realities and to the values of nonliberal East Asian political traditions such as Confucianism and Legalism. Local knowledge is therefore essential for realistic and morally informed contributions to debates on political reform in the region, as well as for mutual learning and enrichment of political theories. Beyond Liberal Democracy is indispensable reading for students and scholars of political theory, Asian studies, and human rights, as well as anyone concerned about China's political and economic future and how Western governments and organizations should engage with China.

Gunn told me once that he had gone on a picnic on Primrose Hill with Ted and Sylvia. What was she like? She seemed a very good mother, Thom said, recalling the picnic basket she had prepared, adding that famous people never seemed to behave characteristically when he met them. Although neither Gunn nor Plath could have known it, they would come to have something deeply personal in common. Gunn's mother was a suicide who left her body for her children (...) (in her case, two teenage sons) to find in the morning. His poem about it is called “The Gas-Poker.”Readers may ask whether we do not already know enough about Sylvia and Ted. The bite mark on his cheek where she drew blood the night they met, the cup of warm milk set out for her toddlers to find with her body in the morning. This detail—the cup of warm milk cooled to frigid temperatures during a night that was one of the coldest on record locally—is, for me, the hardest to forgive. But Clark, drawing on a vast reservoir of evidence and anecdote amassed over years, is able to construct a more nuanced impression of Plath than we have had before. There are missteps, as when Clark complains of Plath's “popular, clichéd image as the Marilyn Monroe of the literati.” No one who has ever heard the breathy voice of Monroe singing “Happy Birthday, Mr. President” and compared it to the plummy, matronly, decidedly upper-class voice Plath cultivated for the BBC can believe that any such cliché exists. Plath mythologized her own life, but Clark succeeds in weaving a tight fabric of minutiae that permits the reader to see what Plath was doing at almost any hour of any particular day. In this steady neutral light, she becomes more fully human. (shrink)

This paper casts doubt on a recent criticism of Frege's theory of concepts and extensions by showing that it misses one of Frege's most important contributions: the derivation of the infinity of the natural numbers. We show how this result may be incorporated into the conceptual structure of Zermelo- Fraenkel Set Theory. The paper clarifies the bearing of the development of the notion of a real-valued function on Frege's theory of concepts; it concludes with a brief discussion of the claim (...) that the standard interpretation of second-order logic is necessary for the derivation of the Peano Postulates and the proof of their categoricity.

Background: Fetal alcohol spectrum disorder (FASD), a complex diagnosis that includes a wide range of neurodevelopmental disabilities, results from exposure to alcohol in the womb. FASD remains poorly understood by Canadians, which could contribute to reported stigma faced by both people with FASD and women who drink alcohol while pregnant. Methods: To better understand how information about FASD is presented in the public sphere, we conducted content analysis of 286 articles from ten major English-language Canadian newspapers (2002-2015). We used inductive (...) coding to derive a coding guide from the data, and then iteratively applied identified codes back onto the sample, checking inter-coder reliability. Results: We identified six major themes related to clinical and scientific media content: 1) prevalence of FASD and of women’s alcohol consumption; 2) research related to FASD; 3) diagnosis of FASD; 4) treatment of FASD and maternal substance abuse; 5) primary disabilities associated with FASD; and 6) effects of alcohol exposure during pregnancy. Discussion: Across these six themes, we discuss three instances of ethically consequential exaggeration and misrepresentation: 1) exaggeration about FASD rates in Indigenous communities; 2) contradiction between articles about the effects of prenatal alcohol exposure; and 3) scientifically accurate information that neglects the social context of alcohol use and abuse by women. Respectively, these representations could lead to harmful stereotyped beliefs about Indigenous peoples, might generate confusion about healthy choices during pregnancy, and may unhelpfully inflame debates about sensitive issues surrounding women’s choices.

Herr Royce ist doch ein bedeutender Denker und darf nur als solcher behandelt werden.("Royce is an important thinker, and may only be treated as such.")Scholars of pragmatism and of phenomenology have observed striking similarities between Josiah Royce and Edmund Husserl, foundational thinkers at the origins of two major philosophical movements whose effects are still strongly felt in the present day—Royce being considered a central founder of American pragmatic idealism, and Husserl of modern German phenomenology. Other scholars have noted striking similarities (...) between Royce's thought and that of the broader circle of phenomenology.2Can we discover in these relations definitive historical influences, rather than ..

Developments in neuroscience have raised the possibility that pharmaceuticals may be used to enhance memory, mood, and attention in people who do not have an illness or disorder, a practice known as “cognitive enhancement.” We describe historical experiences with two medicinal drugs for which similar enhancement claims were made, cocaine in the late 19th and early 20th centuries, and amphetamines in the mid 20th century. These drugs were initially introduced as medicinal agents in Europe and North America before becoming more (...) widely used for a variety of purposes, including what would nowadays be considered cognitive enhancement. Their trajectory of use conformed to the typical use cycle of psychotropic drugs. There was an initial steep rise in prescribing for medical use, followed by expanded nonmedical use that was fueled by enthusiasm for the drugs’ effects. As the number of regular users increased, problems related to use (such as addiction) became apparent, societal concern increased, and laws were passed banning nonmedical use and eventually, medical use. This historical experience draws attention to the adverse side effects of enhancement use that only become apparent with regular, wide-scale use of a drug. We highlight the similarities between the enthusiasms for cocaine and amphetamines and the current enthusiasms for using prescription stimulants for cognitive enhancement. We argue bioethicists should not encourage the cognitive enhancement use of drugs such as methylphenidate in the absence of evidence on the efficacy and safety of their use for cognitive enhancement purposes.

Addiction is increasingly described as a “chronic and relapsing brain disease”. The potential impact of the brain disease model on the treatment of addiction or addicted individuals’ treatment behaviour remains uncertain. We conducted a qualitative study to examine: (i) the extent to which leading Australian addiction neuroscientists and clinicians accept the brain disease view of addiction; and (ii) their views on the likely impacts of this view on addicted individuals’ beliefs and behaviour. Thirty-one Australian addiction neuroscientists and clinicians (10 females (...) and 21 males; 16 with clinical experience and 15 with no clinical experience) took part in 1 h semi-structured interviews. Most addiction neuroscientists and clinicians did not uncritically support the use of brain disease model of addiction. Most were cautious about the potential for adverse impacts on individuals’ recovery and motivation to enter treatment. While some recognised the possibility that the brain disease model of addiction may provide a rationale for addicted persons to seek treatment and motivate behaviour change, Australian addiction neuroscientist and clinicians do not assume that messages about “diseased brains” will always lead to increased treatment-seeking and reduced drug use. Research is needed on how neuroscience research could be used in ways that optimise positive outcomes for addicted persons. (shrink)

This paper presents a new theory of modal reasoning, i.e. reasoning about what may or may not be the case, and what must or must not be the case. It postulates that individuals construct models of the premises in which they make explicit only what is true. A conclusion is possible if it holds in at least one model, whereas it is necessary if it holds in all the models. The theory makes three predictions, which are corroborated experimentally. First, conclusions (...) correspond to the true, but not the false, components of possibilities. Second, there is a key interaction: it is easier to infer that a situation is possible as opposed to impossible, whereas it is easier to infer that a situation is not necessary as opposed to necessary. Third, individuals make systematic errors of omission and of commission. We contrast the theory with theories based on formal rules. (shrink)

Background: Mild traumatic brain injury results from an external force to the head or body causing neurophysiological changes within the brain. The number and severity of symptoms can vary, with some individuals experiencing rapid recovery, and others having persistent symptoms for months to years, impacting their quality of life. Current rehabilitation is limited in its ability to treat persistent symptoms and novel approaches are being sought to improve outcomes following mTBI. Neuromodulation is one technique used to encourage adaptive neuroplasticity within (...) the brain.Objective: To systematically review the literature on the efficacy of neuromodulation in the mTBI population.Method: A systematic review was conducted using Medline, Embase, PsycINFO, PsycARTICLES and EBM Review. Preferred Reporting Items for Systematic Reviews and the Synthesis Without Meta-analysis reporting guidelines were used and a narrative review of the selected studies was completed. Fourteen articles fulfilled the inclusion criteria which were published in English, investigating an adult sample and using a pre- and post-intervention design. Studies were excluded if they included non-mild TBI severities, pediatric or older adult populations.Results: Thirteen of fourteen studies reported positive reductions in mTBI symptomatology following neuromodulation. Specifically, improvements were reported in post-concussion symptom ratings, headaches, dizziness, depression, anxiety, sleep disturbance, general disability, cognition, return to work and quality of life. Normalization of working memory activation patterns, vestibular field potentials, hemodynamics of the dorsolateral prefrontal cortex and excessive delta wave activity were also seen. The studies reviewed had several methodological limitations including small, heterogenous samples and varied intervention protocols, limiting generalisability. Further research is required to understand the context in which neuromodulation may be beneficial.Conclusions: While these positive effects are observed, limitations included unequal representation of neuromodulation modalities in the literature, and lack of literature describing the efficacy of neuromodulation on the development or duration of persistent mTBI symptoms. Better clarity regarding neuromodulation efficacy could have a significant impact on mTBI patients, researchers, clinicians, and policy makers, facilitating a more productive post-mTBI population. Despite the limitations, the literature indicates that neuromodulation warrants further investigation. PROSPERO registration number: CRD42020161279. (shrink)

The deontic model of justice and ethical behavior proposes that people care about justice simply for the sake of justice. This is an important consideration for business ethics because it implies that justice and ethical behavior are naturally occurring phenomena independent of system controls or individual self-interest. To date, research on the deontic model and third-party reactions to injustice has focused primarily on individuals’ tendency topunishtransgressors. This research has revealed that witnesses to injustice will consider sacrificing their own resources if (...) it is the only way to sanction an observed transgressor. In this paper we seek to extend this model by arguing that punishment may not be the only “deontic” reaction, and that in fact, third-party observers of injustice may engage in moral self-regulation that would lead them to conclude that the most ethical response is to do nothing. We provide preliminary evidence for our propositions using voiced cognitions data collected during a resource allocation task. Results indicate that deonance may be more complex than originally thought, and previous tests of the model conservative in nature. (shrink)

Healthcare environments continue to prove discriminatory and marginalizing towards patients and healthcare workers themselves, which contributes to inequitable health outcomes across lines of socially constructed difference. This content and discourse analysis of nursing identity scholarship asks whether there is a connection between nursing identity and oppressive behaviour by examining the construction of nursing identity and the foundational discourses, sometimes in absentia, that support such a construction. Bourdieu's concepts of social fields and Audre Lorde's concept of the master's house are applied (...) as a framework towards understanding the constructs of power and status in healthcare. The analysis identifies a gap in nursing identity literature where social constructs of difference are not considered. In the reviewed literature, nursing identity has been co‐opted by the professionalization project in effort to stabilize a conceptualization of nursing's contribution to healthcare towards gaining professional and societal status. This leads to a monolithic, apolitical representation of nursing identity that erases difference, denies historical influence, universalizes nursing work and further marginalizes marginalized identities. The oppressive and hegemonic nature of a universal nursing identity may contribute to a lack of disciplinary reflexivity about the ongoing influences of foundational discursive constructs of gender, epistemology, power and professional status.

In the article “Nudging and Informed Consent”, Cohen argues that the use of “nudging” by physicians in the clinical encounter may be ethically warranted because it results in an informed consent where obligations for beneficence and respect for autonomy are both met. However, the author's overenthusiastic support for nudging and his quick dismissal of shared decision-making leads him to assume that “soft” manipulation is un-problematic and that “wisdom” on the side of medical professionals will suffice to guard against abuse. Opposing (...) this view, we propose that: 1) patient preferences and values should not be boiled down to rational or irrational decisions based on cognitive reasoning alone, 2) potential threats to the physician-patient must be mitigated and could be minimized by employing alternative strategies that acknowledge the impact of cognitive heuristics in shaping decision-making but maintain transparency and trust, and 3) patient preferences and values can be legitimately influenced only under specific circumstances. The latter include: (1) exhaustion of other means; (2) evidence that nudging is effective in a specific context; (3) evidence of clear and active public misinformation (e.g., industry promoting smoking); (4) explicit pubic dialogue between various stakeholders including medical professional societies about nudging; (5) upholding shared decision-making as a preferred approach; and (6) a rich understanding of clinical reality beyond the simple dichotomy of beneficence-autonomy.

Traditionally, expressions in formal systems have been regarded as signifying finite inscriptions which are—at least in principle—capable of actually being written out in primitive notation. However, the fact that (first-order) formulas may be identified with natural numbers (via "Gödel numbering") and hence with finite sets makes it no longer necessary to regard formulas as inscriptions, and suggests the possibility of fashioning "languages" some of whose formulas would be naturally identified as infinite sets . A "language" of this kind is called (...) an infinitary language : in this article I discuss those infinitary languages which can be obtained in a straightforward manner from first-order languages by allowing conjunctions, disjunctions and, possibly, quantifier sequences, to be of infinite length. In the course of the discussion it will be seen that, while the expressive power of such languages far exceeds that of their finitary (first-order) counterparts, very few of them possess the "attractive" features (e.g., compactness and completeness) of the latter. Accordingly, the infinitary languages that do in fact possess these features merit special attention. (shrink)

The term conceptual simulation refers to a type of everyday reasoning strategy commonly called “what if” reasoning. It has been suggested in a number of contexts that this type of reasoning plays an important role in scientific discovery; however, little direct evidence exists to support this claim. This article proposes that conceptual simulation is likely to be used in situations of informational uncertainty, and may be used to help scientists resolve that uncertainty. We conducted two studies to investigate the relationship (...) between conceptual simulation and informational uncertainty. Study 1 was an in vivo study of expert scientists; the results suggest that scientists do use conceptual simulation in situations of informational uncertainty, and that they use conceptual simulation to make inferences from their data using the analogical reasoning process of alignment by similarity detection. Study 2 experimentally manipulated experts' level of uncertainty and provides further support for the hypothesis that conceptual simulation is more likely to be used in situations of informational uncertainty. Finally, we discuss the relationship between conceptual simulation and other types of reasoning using qualitative mental models. (shrink)

Some attitudes typically take whole persons as their objects. Shame, contempt, disgust and admiration have this feature, as do many tokens of love and hate. Objectors complain that these ‘globalist attitudes’ can never fit their targets and thus can never be all-things-considered appropriate. Those who dismiss all globalist attitudes in this way are misguided. The fittingness objection depends on an inaccurate view of the person-assessments at the heart of the globalist attitudes. Once we understand the nature of globalist attitudes and (...) we recognize that we may legitimately treat some traits as more important than others in our overall evaluation of persons, we ought to conclude that our globalist attitudes can, in some cases, fit their targets and should not be summarily dismissed as unfitting. Our relationships contour the fittingness-conditions of globalist attitudes. This relational element poses a problem for fitting-attitude theories of value. (shrink)

The infinitesimal methods commonly used in the 17th and 18th centuries to solve analytical problems had a great deal of elegance and intuitive appeal. But the notion of infinitesimal itself was flawed by contradictions. These arose as a result of attempting to representchange in terms ofstatic conceptions. Now, one may regard infinitesimals as the residual traces of change after the process of change has been terminated. The difficulty was that these residual traces could not logically coexist with the static quantities (...) traditionally employed by mathematics. The solution to this difficulty, as it turns out, is to regard these quantities asalso being subject to (a form of) change, for then they will have the same nature as the infinitesimals representing the residual traces of change, and will become,ipso facto, compatible with these latter.In fact, the category-theoretic models which realize the Principle of Infinitesimal Linearity may themselves be regarded as representations of a general concept of variation (cf. Bell (1986)). While the static set-theoretical models represent change or motion by making a detour through the actual (but static) infinite, the varying category-theoretic models enable such change to be representeddirectly, thus permitting the introduction of geometric infinitesimals and, as we have attempted to demonstrate in this paper, the virtually complete incorporation of the methods of the early calculus.It is surely a remarkable — even an ironic — fact that the contradiction between the flux of the objective world and the stasis of mathematical entities has found its resolution in category theory, a branch of mathematics commonly, and, as one now sees, mistakenly, regarded as the summit of gratuitous abstraction.

In Setting Limits, Daniel Callahan advances the provocative thesis that age be a limiting factor in decisions to allocate certain kinds of health services to the elderly. However, when one looks at available data, one discovers that there are many more elderly women than there are elderly men, and these older women are poorer, more apt to live alone, and less likely to have informal social and personal supports than their male counterparts. Older women, therefore, will make the heaviest demand (...) on health care resources. If age were to become a limiting factor, as Dr. Callahan sug-gests it should, the limits that will be set are limits that will affect women more dras” tically than they affect men. This review essay examines the implications of Callahan's thesis for elderly women. (shrink)

In the study of women in academia, the focus is often particularly on women’s stark underrepresentation in the math-intensive fields of natural sciences, technology, and economics. In the non-math-intensive of fields life, social and behavioral sciences, gender issues are seemingly less at stake because, on average, women are well-represented. However, in the current study, we demonstrate that equal gender representation in LSB disciplines does not guarantee women’s equal opportunity to advance to full professorship—to the contrary. With a cross-sectional survey among (...) N = 2,109 academics at mid-level careers in the Netherlands, we test the hypothesis that in LSB, female academics perceive to hit a “thicker” glass ceiling—that is, they see a sharper contrast between the high representation of women at the lower compared to the top levels. We test whether this predicts female academics’ lower estimated chances to reach full professorship relative to men in LSB. We introduce a novel perceived glass ceiling index, calculated based on academics’ perceptions of the share of women and men in their direct work environment minus their perceptions of gender ratio among full professors in their field. Results confirm that the perceived glass ceiling is thicker in the non-math-intensive LSB compared to math-intensive NTE fields. Furthermore, only in LSB, women perceived a thicker glass ceiling than men. Moreover, only among female academics, the thicker the perceived glass ceiling, the lower their estimated chances to become full professor 1 day. Combined, a moderated mediation showed that for women only, a thicker perceived glass ceiling in LSB compared to NTE disciplines predicted their lower estimated chances to advance to full professor level. No such mediation occurred for men. We conclude that women’s higher numerical representation in LSB disciplines does not negate a male-dominant normative standard about academic leadership and success. Paradoxically, the perceived odds for female academics to reach the top of their field are lower in fields where they are relatively highly represented, and this may pose unique barriers to women’s perceived opportunities for career success.

The perception of behavior as a moral or conventional concern can be influenced by contextual variables, including status and power differences. We propose that social processes and in particular social role enactment through the exercise of power will psychologically motivate moralization. Punishing or rewarding others creates a moral dilemma that can be resolved by externalizing causation to incontrovertible moral rules. Legitimate power related to structure and position can carry moral weight but may not influence the power holder’s perceptions of rules (...) and general norms of behavior. Social identity theory suggests moralization could be promoted by a concern for shared, defining values. However, the tendency to moralize another’s behavior can be injurious to shared identity. We explored white-collar employees’ perceptions of several categories of noxious or deviant workplace behaviors and regressed these perceptions on the tendency to use legitimate, referent, or reward and punish power; social identity; and the interaction of social identity and power, in particular legitimate power. Only the tendency to influence others through punishment or reward predicted moralization. Alternative causal explanations for the findings were addressed through the absence of any relationships between punishment and reward power and perceptions of deviant behaviors as wrong, upsetting, or requiring punishment. We discuss these results in the context of self and social processes, the social construction of morals and power, and the impact of managers’ behavior on group or organizational ethics. (shrink)

Liberalism and ecologism are widely regarded as incompatible. Liberalism and (anthropocentric) environmentalism might be compatible but liberalism and (non-anthropocentric) ecologism are not. A liberal state cannot promote policies for ecological or ecocentric reasons. An individual cannot be both a liberal and a committed advocate of ecologism. This paper challenges these claims. It is argued that Rawls’s ‘political liberalism’ is compatible with ecologism and, in particular, the idea of ‘ecological justice’. A Rawlsian state can promote ecological justice. A committed political liberal (...) can also be a committed advocate of ecological justice. The argument is developed through a close textual examination of Rawls’s brief discussion of our duties to ‘animals and the rest of nature’. Rawls leaves far more scope for liberal ecologism than his critics have suggested. The proposed version of liberal ecologism is defended against charges of substantive and procedural bias toward humans and against nonhuman nature. Liberal ecologism may not be enough for some ecologists-especially ‘ecological constitutionalists’ seeking constitutional protection for nonhuman nature-but it is a serious and defensible political and moral theory.

Over the past 25 years, there has been growing recognition of the importance of studying the Ethical, Legal and Social Implications of genetic and genomic research. A large investment into ELSI research from the National Institutes of Health Human Genomic Project budget in 1990 stimulated the growth of this emerging field; ELSI research has continued to develop and is starting to emerge as a field in its own right. The evolving subject matter of ELSI research continues to raise new research (...) questions as well as prompt re-evaluation of earlier work and a growing number of scholars working in this area now identify themselves as ELSI scholars rather than with a particular discipline. Due to the international and interdisciplinary nature of ELSI research, scholars can often find themselves isolated from disciplinary or regionally situated support structures. We conducted a workshop with Early Career Researchers in Oxford, UK, and this paper discusses some of the particular challenges that were highlighted. While ELSI ECRs may face many of the universal challenges faced by ECRs, we argue that a number of challenges are either unique or exacerbated in the case of ELSI ECRs and discuss some of the reasons as to why this may be the case. We identify some of the most pressing issues for ELSI ECRs as: interdisciplinary angst and expertise, isolation from traditional support structures, limited resources and funding opportunities, and uncertainty regarding how research contributions will be measured. We discuss the potential opportunity to use web 2.0 technologies to transform academic support structures and address some of the challenges faced by ELSI ECRs, by helping to facilitate mentoring and support, access to resources and new accreditation metrics. As our field develops it is crucial for the ELSI community to continue looking forward to identify how emerging digital solutions can be used to facilitate the international and interdisciplinary research we perform, and to offer support for those embarking on, progressing through, and transitioning into an ELSI research career.

Funding: Research funded by Canadian Institutes of Health Research, NNF 80045, States of Mind: Emerging Issues in Neuroethics. While there are those who object to the prospective use of propranolol to prevent or treat post-traumatic stress disorder (PTSD), most obstreperous among them the President’s Council on Bioethics, the use of propranolol can be justified for patients with severe PTSD. Propranolol, if effective, will alter the quality of certain memories in the brain. But this is not a serious threat to the (...) self understood in terms of narrative identity. A narrative identity framework acknowledges that memory is always being subtly altered or modified. For severe cases of PTSD propranolol may help victims who don’t respond to any other therapy or therapy combination regain their authentic self-narrative and engage once more in life activities. For those whose symptoms are not so severe the potential risks and side-effects of the drug may outweigh the benefits. Patients and family members should be allowed to decide, in consultation with their physician, whether this drug is appropriate in their case. (shrink)

Deep brain stimulation (DBS) has been proposed as a potential treatment of drug addiction on the basis of its effects on drug self-administration in animals and on addictive behaviours in some humans treated with DBS for other psychiatric or neurological conditions. DBS is seen as a more reversible intervention than ablative neurosurgery but it is nonetheless a treatment that carries significant risks. A review of preclinical and clinical evidence for the use of DBS to treat addiction suggests that more animal (...) research is required to establish the safety and efficacy of the technology and to identify optimal treatment parameters before investigating its use in addicted persons. Severely addicted persons who try and fail to achieve abstinence may, however, be desperate enough to undergo such an invasive treatment if they believe that it will cure their addiction. History shows that the desperation for a cure of addiction can lead to the use of risky medical procedures before they have been rigorously tested. In the event that DBS is used in the treatment of addiction, we provide minimum ethical requirements for clinical trials of its use in the treatment of addiction. These include: restrictions of trials to severely intractable cases of addiction; independent oversight to ensure that patients have the capacity to consent and give that consent on the basis of a realistic appreciation of the potential benefits and risks of DBS; and rigorous assessments of the effectiveness and safety of this treatment compared to the best available treatments for addiction.

:Resentment and other hard feelings may outlive their targets, and people often express a desire to overcome these feelings through forgiveness. While some see forgiving the dead as an important moral accomplishment, others deny that genuine forgiveness of the dead is coherent, let alone desirable or valuable. According to one line of thought, forgiveness is something we do for certain reasons, such as the offender’s expressed contrition. Given that the dead cannot express remorse, forgiveness of the dead is impossible. Others (...) see the apparent coherence and moral importance of forgiving the dead as a reason to give up on the idea that forgiveness is conditional upon the offender’s remorse. According to these philosophers, forgiveness of the dead poses no special problems; forgiveness of the dead, like forgiveness of the living, is not contingent upon the offender’s contrition. I steer a path between these two positions in such a way as to bring out an important aspect of forgiveness that is not adequately addressed in the literature: I argue that forgiving the dead may be perfectly coherent and morally valuable even though the dead cannot ask for forgiveness or engage in reparative activities. A full appreciation of the relational character of forgiveness allows us to make sense of forgiving the dead. (shrink)

In the last years, TV documentaries, articles in popular magazines, and Internet content have increased the public visibility of deep brain stimulation (DBS). The media may have also provoked significant clinical and public interest in potential future applications for treating psychiatric disorders beyond the current use of DBS in neurological disorders. In this article, we review and discuss the topic of patient and public understanding of DBS, focusing on both the clinical consequences of patient understanding as well as the broader (...) social consequences of public understanding. The literature and the experience of clinicians suggest that strongly optimistic media reports of DBS have had detrimental consequences for informed consent and the management of patient expectations before and after surgery. Likewise, this context has created complex issues for trust between clinicians, patients, and their families and may have hard-to-predict social impacts including on the relationships between public understanding of neuroscience, biological therapies, stigma, and mental illness. We propose an approach to tackle the clinical and social consequences of media messages on public understanding within a broad and interdisciplinary effort with concrete actions. This approach includes actions by all key players, including not only providers but also patients and their family members, as well as journalists. To further address issues at the intersection of informed consent and patient expectation, there should be more discussion on and actual testing and measurement of these recommendations or similarly minded practice changes.

In May 2009 the World Health Assembly passed a resolution on reducing health inequities through action on the social determinants of health, based on the work of the global Commission on Social Determinants of Health, 2005–2008. The Commission's genesis and findings raise some important questions for global health governance. We draw out some of the essential elements, themes, and mechanisms that shaped the Commission. We start by examining the evolving nature of global health and the Commission's foundational inspiration – the (...) universal pattern of health inequity and the imperative, driven by a sense of social justice, to make better and more equal health a global goal. We look at how the Commission was established, how it was structured internally, and how it developed external relationships – with the World Health Organization, with global networks of academics and practitioners, with country governments eager to spearhead action on health equity, and with civil society. We outline the Commission's recommendations as they relate to the architecture of global health governance. Finally, we look at how the Commission is catalyzing a movement to bring social determinants of health to the forefront of international and national policy discourse. (shrink)

In the present paper the concept of a covering is presented and developed. The relationship between cover schemes, frames (complete Heyting algebras), Kripke models, and frame-valued set theory is discussed. Finally cover schemes and framevalued set theory are applied in the context of Markopoulou’s account of discrete spacetime as sets “evolving” over a causal set. We observe that Markopoulou’s proposal may be effectively realized by working within an appropriate frame-valued model of set theory. We go on to show that, within (...) this framework, cover schemes may be used to force certain conditions to prevail in the associated models: for example, rendering the universe timeless, obliterating a given event or forcing it to become the universe’s “beginning”.

The opposed concepts of continuity and discreteness have figured prominently in the development of mathematics, and have also commanded the attention of philosophers. Continuous entities may be characterized by the fact that they can be divided indefinitely without altering their essential nature. So, for instance, the water in a bucket may be indefinitely halved and yet remain water. (For the purposes of illustration I ignore the atomic nature of matter which has been established by modern physics.) Discrete entities, on the (...) other hand, typically cannot be divided without effecting a change in their nature: half a wheel is plainly no longer a wheel. Thus we have two contrasting properties: on the one hand, the property of being indivisible, separate or discrete, and, on the other, the property of being indefinitely divisible and continuous although not actually divided into parts.

Firms are under increasing pressure from external forces to do what is right and behave ethically. However, we have only a limited understanding of how ethical and responsible business practices impact the value of the firm, both in the short and the long term. In this study, we examine 196 firms that were recognized as the world's most ethical firms from 20 countries over a 14-year span. Results show that ethical behavior may have little effect on a firm's profitability in (...) the short term. However, it has a positive effect on a firm's market value, reflecting the market's positive assessment of its long-term performance. We also find that firms frequently listed among the world's most ethical companies tend to have higher market value than firms listed only once. (shrink)

Few subjects provoke as much controversy or debate as that of medical care, and the law that governs such an emotive area finds itself with the near-impossible task of simultaneously trying to regulate the medical profession and healthcare provision whilst upholding the rights of the millions of people who use those services every year. Medical Law combines an accessible explanation of the complex and challenging legal rules of medical care in England and Wales with a stimulating examination of the social, (...) political and ethical arguments such care provokes. It examines a broad range of issues, from the structure and organisation of the NHS, through the rules of clinical negligence, as well as focussing on the legal and ethical concerns around such deeply contentious areas as surrogacy, organ donation, abortion and euthanasia. Written very much with newcomers to the area in mind, Leanne Bell lucidly outlines not just what the law is, but how it has developed over time and also provides insights as to how advances in medical technology and techniques may call for it to evolve in the future.

The deontic model of justice and ethical behavior proposes that people care about justice simply for the sake of justice. This is an important consideration for business ethics because it implies that justice and ethical behavior are naturally occurring phenomenaindependent of system controls or individual self-interest. To date, research on the deontic model and third-party reactions to injustice has focused primarily on individuals’ tendency to punish transgressors. This research has revealed that witnesses to injustice will consider sacrificing their own resources (...) if it is the only way to sanction an observed transgressor. In this paper we seek to extend this model by arguing that punishment may not be the only “deontic” reaction, and that in fact, third-party observers of injustice may engage in moral self-regulation that would lead them to conclude that the most ethical response is to do nothing. We provide preliminary evidence for our propositions using voiced cognitions data collected during a resource allocation task. Results indicate that deonance may be more complex than originally thought, and previous tests of the model conservative in nature. (shrink)

But while the literature of art is, in publishers' terms, booming, it has in one respect suffered a loss. During the past two hundred years there has usually been some important figure who acted as a censor and an apologist of the contemporary scene, a Diderot, a Baudelaire, a Ruskin or a Roger Frye. Who amongst our living authors plays this important role? What name springs to mind? I would suggest that no name actually springs; the last of our grandly (...) influential critics was Sir Herbert Read and since his death, whatever else modern art may or may not possess, it has no prophet. This is not to say that aesthetic prophets are necessarily desirable nor that there are not some very conscientious and extremely perceptive critics at work today; in view of the fact that I am within a fortnight exhibiting my work in a London dealer's gallery , it would be folly to deny it. But it is I believe true that for better or for worse we have no grand pundit of living art and I believe that this lack may be concerned with what I see as a certain diminution in the role of the art critic, a certain decay in this department of literature. It is a tendency which I regret and the causes of which I want to try to discuss. It arises I believe from a misunderstanding concerning the proper functions of the critic and this confusion of purpose will be my theme. First, however, I think that I should glance at two important circumstances which make the work of an art critic particularly difficult today. Quentin Bell, professor of the history and theory of art at Sussex University, has written Virginia Woolf: A Biography, Of Human Finery, Ruskin, Victorian Artists, and, Bloomsbury. His article, "Art and the Elite," appeared in the first issue of Critical Inquiry. "The Art Critic and the Art Historian" was originally delivered as the Leslie Stephen lecture at the University of Cambridge on November 26, 1973. Other contributions are "CRITICAL RESPONSE: Notes and Exchanges" , and "Bloomsbury and 'the Vulgar Passions'". (shrink)

A structure is a triple A = (A, {Ri: i ∈ I}, {ej: j ∈ J}), where A, the domain or universe of A, is a nonempty set, {Ri: i ∈ I} is an indexed family of relations on A and {ej: j ∈ J}) is an indexed set of elements —the designated elements of A. For each i ∈ I there is then a natural number λ(i) —the degree of Ri —such that Ri is a λ(i)-place relation on A, (...) i.e., Ri ⊆ Aλ(i). This λ may be regarded as a function from I to the set ω of natural numbers; the pair (λ, J) is called the type of A. Structures of the same type are said to be similar. Note that since an n-place operation f: An → A can be regarded as an (n+1)-place relation on A, algebraic structures containing operations such as groups, rings, vector spaces, etc. may be construed as structures in the above sense.

Were Russell alive and still with us, one could apologize to him for the degree of travesty and oversimplification which the present task has involved. But his inspiration is no longer a living one and it is still a live question in the philosophy of logic whether or not it makes sense to apologize to the shades of the departed. Perhaps the author in such a predicament can take some comfort from the possibility that what he has written may interest (...) some reader in that sort of question. (shrink)

In spacetime physics any set C of events—a causal set—is taken to be partially ordered by the relation ≤ of possible causation: for p, q ∈ C, p ≤ q means that q is in p’s future light cone. In her groundbreaking paper The internal description of a causal set: What the universe looks like from the inside, Fotini Markopoulou proposes that the causal structure of spacetime itself be represented by “sets evolving over C” —that is, in essence, by the (...) topos SetC of presheaves on Cop. To enable what she has done to be the more easily expressed within the framework presented here, I will reverse the causal ordering, that is, C will be replaced by Cop, and the latter written as P—which will, moreover, be required to be no more than a preordered set. Specifically, then: P is a set of events preordered by the relation ≤, where p ≤ q is intended to mean that p is in q’s future light cone—that q could be the cause of p, or, equally, that p could be an effect of q. In that case, for each event p, the set p↓ = {q: q ≤ p} may be identified as the causal future of p, or the set of potential effects of p. In requiring that ≤ be no more than a preordering—in dropping, that is, the antisymmetry of ≤—I am, in physical terms, allowing for the possibility that the universe is of Gödelian type, containing closed timelike lines.

Continuous entities are accordingly distinguished by the feature that—in principle at least— they can be divided indefinitely without altering their essential nature. So, for instance, the water in a bucket may be indefinitely halved and yet remain water. Aristotle nowhere to my knowledge defines discreteness as such but we may take the notion as signifying the opposite of continuity—that is, incapable of being indefinitely divided into parts. Thus discrete entities, typically, cannot be divided without effecting a change in their nature: (...) half a wheel is plainly no longer a wheel1. Thus we have two contrasting properties: on the one hand, the property of being indivisible, separate or discrete, and, on the other, the property of being indefinitely divisible and continuous although not actually divided into parts. Still, one and the same object can, in a sense, possess both of these properties. For example, if the wheel is regarded simply as a piece of matter, it remains so on being divided in half. In other words, the wheel qua wheel is discrete, but as a piece of matter, it is continuous. Examples like this show that continuity and discreteness are complementary attributes originating through the mind's ability to perform acts of abstraction, the one arising by abstracting an object’s divisibility and the other its self-identity. In mathematics it is the concept of whole number, later elaborated into the set concept, that provides an embodiment of the idea of pure discreteness, that is, of the idea of a collection of separate individual objects, all of whose properties—apart from their distinctness—have been refined away. The basic mathematical representation of the idea of continuity, on the other hand, is the geometric figure, and more particularly the straight line. By their very nature geometric figures are continuous; discreteness is injected into geometry, the realm of the.. (shrink)

MATHEMATICS AND PHILOSOPHY ARE CLOSELY LINKED, and several great mathematicians who were at the same time great philosophers come to mind— Pythagoras, Descartes and Leibniz, for instance. One great mathematician of the modern era in whose thinking philosophy played a major role was Hermann Weyl (1885–1955), whose work encompassed analysis, number theory, topology, differential geometry, relativity theory, quantum mechanics, and mathematical logic. His many writings are informed by a vast erudition, an acute philosophical awareness, and even, on occasion, a certain (...) playfulness. No matter what the subject may be—mathematics, physics, philosophy—Weyl’s writing fascinates both by the depth of insight it reveals and by its startling departures from academic convention. Who else would have the daring to liken (as he does in the discussion of Space and Time in his Philosophy of Mathematics and Natural Science), a coordinate system to “the residue of the annihilation of the ego”1? Or then (somewhat further on in the same discussion) to express the belief in the impossibility of a completely objective account of individual consciousness by the assertion “...it is shattered by Judas’ desperate outcry, ‘Why did I have to be Judas?’”2.

We begin with the following quotation from Karp [1964]: My interest in infinitary logic dates back to a February day in 1956 when I remarked to my thesis supervisor, Professor Leon Henkin, that a particularly vexing problem would be so simple if only I could write a formula which would say x = 0 or x = 1 or x = 2 etc. To my surprise, he replied, "Well, go ahead." Traditionally, expressions in formal systems have been regarded as signifying (...) finite inscriptions which are—at least in principle—capable of actually being written out in primitive notation. However, the fact that (first-order) formulas may be identified with natural numbers (via "Gödel numbering") and hence with finite sets makes it no longer necessary to regard formulas as inscriptions, and suggests the possibility of fashioning "languages" some of whose formulas— such as that in the above quotation—would be naturally identified as infinite sets. A "language" of this kind is called an infinitary language: in this article we discuss those infinitary languages which can be obtained in a straightforward manner from first-order languages by allowing conjunctions, disjunctions and, possibly, quantifier sequences, to be of infinite length. In the course of the discussion we shall see that, while the expressive power of such languages far exceeds that of their finitary (first-order) counterparts, very few of them possess the "attractive" features (e.g., compactness and completeness) of the latter. Accordingly, the infinitary languages that do in fact possess these features merit special attention. In §1 we lay down the basic syntax and semantics of infinitary languages and demonstrate their expressive power by means of examples. §2 is devoted to those infinitary languages which permit only finite quantifier sequences: these languages turn out to be relatively well-behaved. In §3 we discuss the compactness problem for infinitary languages and its.. (shrink)

We are all familiar with the idea of a set, also called a class or collection. As examples, we may consider the set of all coins in one's pocket, the set of all human beings, the set of all planets in the solar system, etc. These are all concrete sets in the sense that the objects constituting them—their elements or members—are material things. In mathematics and logic we wish also to consider abstract sets whose members are not necessarily material things, (...) but abstract entities such as numbers, lines, ideas, names, etc. We shall use the term set to cover concrete and abstract sets, as well as sets which contain a mixture of material and abstract elements.

A formal, logical, theory of events is developed and used as the basis for a definition of causation and to provide a pragmatics for causal counterfactuals. The theory begins with with a logical formalization of events as represented in the planner strips. The resulting inertial theories include a common sense law of inertia and their pragmatics is based on the principle of chronological minimization. The theory of events is then developed by removing some of the simplifying assumptions of the strips (...) representation. To begin with the assumption that events always succeed, given that their preconditions are true when they occur, is dropped. Instead a common sense law of change is introduced with the effect that events normally succeed but may fail if some qualification (some unusual or unexpected condition) arises. The pragmatics of the resulting causal theories is provided by refining the pragmatics of inertial theories. In particular, where there is a conflict between change and inertia, preference is given to change. The resulting defeasibility of events makes it possible to remove the strips assumption that only one event occurs at any given time; as conflicting events now result in failure rather than inconsistency. However it is desirable to provide a means for adjudicating between conflicting events. Consequently the theory is extended so that qualification preferences can be specified and the pragmatics are refined accordingly. A further strips assumption is that the effects of an event are invariant. In order to remove this assumption a distinction is drawn between primary events, events of the kind described above, and secondary events. Secondary events are invoked by primary events in appropriate contexts, they are causally dependent on primary events and when successful produce the additional, variant, effects of the primary events which invoke them. As a result, both the context-dependent effects of events (their ramifications) and non-deterministic events (events whose outcome is uncertain) can be represented. The theory of primary and secondary events is then used as the basis for a definition of causation which can be seen as providing a formal account of Mackie's definition of a cause as an inus condition. A major theme of this paper is the conflict between the opposite but complementary principles of change and inertia. For much of the paper the emphasis is on restricting the effects of inertia and favouring change. The resulting imbalance becomes unnatural when considering the combined effects of several events. However the definition of causation makes it possible to state a law of change and inertia, which is used to regulate change and inertia and thus ensure a proper balance between them: while caused change is preferred to inertia, inertia is preferred to uncaused change. The theory is then used to provide a pragmatics for causal counterfactuals, thereby extending the representation of actual causal reasoning to counterfactual causal reasoning. This is illustrated by the use of causal counterfactuals in order to obtain explanations. (shrink)

Background There are numerous ethical challenges that can impact patients and families in the health care setting. This paper reports on the results of a study conducted with a panel of clinical bioethicists in Toronto, Ontario, Canada, the purpose of which was to identify the top ethical challenges facing patients and their families in health care. A modified Delphi study was conducted with twelve clinical bioethicist members of the Clinical Ethics Group of the University of Toronto Joint Centre for Bioethics. (...) The panel was asked the question, what do you think are the top ten ethical challenges that Canadians may face in health care? The panel was asked to rank the top ten ethical challenges throughout the Delphi process and consensus was reached after three rounds. Discussion The top challenge ranked by the group was disagreement between patients/families and health care professionals about treatment decisions. The second highest ranked challenge was waiting lists. The third ranked challenge was access to needed resources for the aged, chronically ill, and mentally ill. Summary Although many of the challenges listed by the panel have received significant public attention, there has been very little attention paid to the top ranked challenge. We propose several steps that can be taken to help address this key challenge. (shrink)
