De Marco et al 1 argue that the standard account of medical ‘invasiveness’ (as ‘incision’ or ‘insertion’) fails to capture three aspects of its existing use, namely that invasiveness can come in degrees, often depends on features of alternative medical interventions and can be non-physical. They propose a new schematic account that suggests that medical interventions can possess ‘basic invasiveness’ (which can come in degrees and of which they suggest at least two types: physical and mental), and ‘threshold invasiveness’ which (...) can depend on the alternatives a specific intervention is being compared with. While we agree that the standard account of invasiveness fails to capture existing use and are supportive of their aim, here we express scepticism about the practical utility of De Marco et al ’s revised account. Our scepticism concerns the application of De Marco et al’s revised account in the narrow context of clinician–patient communication and deliberation about medical interventions within clinical practice, which we see as a crucial context for its use. While De Marco et al do not specify the contexts in which their revised account could be used, we assume from their discussion of treatment interventions (e.g. non-invasive prenatal testing, ventilation) and their comparison to ‘more or less invasive’ options, that at least one of the purposes in mind for ….

The popularity of direct-to-consumer genetic ancestry services has exploded over the past five years, with as many as 250 direct-to-consumer genetic ancestry testing companies currently operating and estimates that 1 in 5 Americans are customers of one or more of those companies. Marketing of genetic ancestry testing has consistently linked the results of DNA testing to a consumer’s racial and ethnic identity, and, because of that, can help consumers find out “who they really are.” We argue that the “biologization” of (...) race and ethnicity promoted in such marketing violates norms of marketing ethics. In particular, we show that this marketing technique violates a number of the core commitments and values of the American Marketing Association Statement of Ethics. (shrink)

An adolescent’s last moment of life is an emotionally and medically complex time. Children may grapple with understanding the things happening to them and with grief of a future lost; caregivers struggle to simultaneously balance deep sorrow, hope, and love; and healthcare providers fight to maintain sound medical and ethical decision making. Increased discussion regarding adolescent end-of-life care is needed so that clinicians may better understand how to engage in ethically based medical management during these events. This holds particularly true (...) in situations where potentially conflicting ideas exist between clinicians and family members. We describe the case of an acutely and terminally ill adolescent who remained cognitively intact but with rapidly advancing multiple organ failure and whose parents requested that he remain uninformed of his critical illness and prognosis.

Philosophy of religion has been the object of penetrating critiques concerning its continued near-complete blindness to all but a single religion. The need for philosophy of religion to open up so as to include more than merely occasional and tokenistic treatments of ‘Other’ religions is clearly evident from the slew of recently published titles concerned with diversifying the field. In this light, a book such as Victoria Harrison’s Eastern Philosophy of Religion should surely come as a welcome addition. And yet, (...) unfortunately, this book turns out to be a case study in how not to diversify philosophy of religion in the twenty-first century. (shrink)

Suppose COVID-19 is the runaway tram in the famous moral thought experiment, known as the “Bystander at the Switch.” Consider the two differentiated responses of governments around the world to this new threat, namely the option of quarantine/lockdown and herd immunity. Can we contrast the hypothetical with the real scenario? What do the institutional decisions and strategies for dealing with the virus, in the beginning of 2020, signify in a normative moral framework? This paper investigates these possibilities in order to (...) highlight the similarities and, more importantly, the differences that exist between utilitarianism and Kantian ethics. Analysis shows that the hypothetical scenario can never be fully compared to the complex multifactorial nature of the real world. But if a comparison is attempted, the most obvious difference between the two governmental strategies is the concept of duty within the Kantian perspective. Ultimately, it is a matter of comparing freedom and life. Attributing a moral “priority ticket” to one or the other can be analysed through interpersonal aggregation. (shrink)

This article argues that the literary contexts of Horace's Odes 3.13, especially archaic Greek poetry, have been relatively neglected by scholars, who have focussed on identifying the location of the fons Bandusiae and on understanding the significance of the sustained description of the kid sacrifice. This study presents a more holistic interpretation of the ode by exploring Horace's interactions with previously unnoticed (Alcaeus, frr. 45 and 347) and underappreciated (Hes. Op. 582–96) archaic Greek poetic intertexts, which also offer a fresh (...) perspective on earlier debates. Horace's use of Alcaeus’ fr. 45, a key intertext, firmly places the fons Bandusiae within the literary landscape of Horace's Sabine estate, and offers a structural and argumentative model for Odes 3.13; further, Alcaean and Hesiodic allusions also suggest that the kid is sacrificed as a surrogate for Horace for keeping him safe. These conclusions are used to offer a new interpretation of the ode on metapoetic, political and philosophical levels, and to explore how these different aspects of the ode interact with Horace's other odes.

On the basis of the archival materials, first identified by the authors, and the published historical sources that have not yet come to the attention of historians of science, this article reconstructs the biography of Johann Christian Weltzien (1767–1829), doctor of medicine and surgery. In 1785, Weltzien became a court physician. In 1799, in the retinue of Grand Duke Konstantin Pavlovich, he participated in Italian and Swiss military campaigns. After that, Weltzien was assigned to the Сourt of Grand Duke Konstantin (...) Pavlovich of Russia and stayed at his court until 1810. He started his charitable activities in the Medico-Philanthropic Committee. From May 1810 to the middle of 1825, Weltzien was a physician at the Imperial Page Corps. It turned out that around the same time, in 1804–1825, he was a member of the Medical Council. Furthermore, as there were two medical councils under two ministries at the time, in 1811–1822, he was a member of both. Since 1825, Weltzien lived on his estate in Somel, now Vaiatu Manor in Estonia, and died in St. Petersburg. Weltzien’s work as a provincial physician prompted him to write a book on medical police, which was published in 1785. It has been established that this remained his only book on the topic. The article shows that Weltzien became one of the first ideologists of state care for public health in the Russian Empire. Weltzien’s ideas, expressed over 200 years ago, regarding the state having mechanisms to impact public health and the importance of not excluding it from solving health problems have not lost their significance even today.

This study analyzed 16 potential ethics-related problems associated with use and abuse of video news releases (VNRs) by public relations practitioners and electronic journalists. Causes and possible solutions to the problems were suggested and model ethics code guidelines were developed. Moral rules, moral ideals, theories of ethics, public relations theories, and electronic journalism theories were used to provide a general foundation for the analysis. A more specific foundation was provided by guidelines from a variety of media codes of ethics.

William James is known as a nineteenth-century philosopher, psychologist, and psychical researcher. Less well-known are the medical fixations that united his multiple identities and drove his ambition to change the way American society conceived of itself in body, mind, and soul. William James, M.D. offers an account of the development and cultural significance of James's ideas and works, and establishes, for the first time, the relevance of medical themes to his major lines of thought. James lived at a time when (...) old assumptions about faith and the moral and religious possibilities for human worth and redemption were increasingly displaced by a concern with the medically "normal" and the perfectibility of the body. Woven into treatises warning of the degeneration of humanity, these ideas comprised the origins of the eugenics movement and were manifest in a growing social stigma attached to illness and invalidism, a disturbing intellectual current in which James felt personally implicated. Most chronicles of James's life have portrayed a distressed young man, a psychological or spiritual crisis, followed by the emergence of a mature thinker who threw off his pallor of mental sickness for good. In contrast, Emma Sutton draws on his personal correspondence, unpublished notebooks, and diaries to show that James considered himself a genuine invalid to the end of his days. Sutton makes the compelling case that his philosophizing was not an abstract occupation but an impassioned response to his own life experiences and challenges. To ignore the medical James is to misread James altogether. Sales points: First book to map William James's preoccupation with medical ideas, concerns, and values across the disciplinary breadth of his work Reveals how themes of invalidism, health, and healing underpinned the genesis of many of James's major philosophical, psychological, and political ideas Draws on the approximately 9,400 items of Jamesian correspondence, together with his private notes and reading lists.

In this article I caution that María Lugones's critiques of Kimberlé Crenshaw's intersectional theory posit a dangerous form of epistemic erasure, which underlies Lugones's decolonial methodology. This essay serves as a critical engagement with Lugones's essay “Radical Multiculturalism and Women of Color Feminisms” in order to uncover the decolonial lens within Crenshaw's theory of intersectionality. In her assertion that intersectionality is a “white bourgeois feminism colluding with the oppression of Women of Color,” Lugones precludes any possibility of intersectionality operating as (...) a decolonial method. Although Lugones states that her “decolonial feminism” is for all women of color, it ultimately excludes Black women, particularly with her misconstruing of Crenshaw's articulation of intersectionality that is rooted within the Black American feminist tradition. I explore Lugones's claims by juxtaposing her rendering of intersectionality with Crenshaw's and conclude that Lugones's decolonial theory risks erasing Black women from her framework. (shrink)

Researchers have postulated that deficits in cognitive control are associated with, and thus may underlie, the perseverative thinking that characterises generalised anxiety disorder. We examined associations between cognitive control and levels of spontaneous state rumination following a stressor in a sample of healthy control participants and participants with GAD. We assessed cognitive control by measuring working memory capacity, defined as the ability to maintain task-relevant information by ignoring task-irrelevant information. To this end, we used an affective version of the reading (...) span task with valenced distractors. Lower WMC in the presence of negative distractors was associated with greater state rumination in the GAD group, but not in the CTL group. These findings suggest that difficulty maintaining task-relevant information due to interference from negative distractors contributes to perseverative thinking in GAD. (shrink)

Many Americans don't hold journalists in very high regard these days, and sports journalists are often viewed in the least favorable light. The general public does not perceive any visible, unified, and concerted effort among sportswriters to practice their craft in a consistently ethical manner. Efforts to upgrade the craft include the Associated Press Sports Editors ethical guidelines, which cover freebies, moonlighting, community involvement by sports journalists, and commercial sponsors of sporting events. This study examines the APSE code and suggests (...) additional, more specific, and enforceable guidelines in ten areas: freebies, moonlighting, newsgathering methods, news sources, direct quotes, privacy, gambling, special interests, self?interests, and involvements. Sports journalists should be as ethically accountable as any other journalists, the author concludes. (shrink)

Self-monitoring theory explains the individual differences in using interpersonal adjustment techniques like self-control, self-regulation, and self-presentation. Self-monitoring plays a key role for understanding the social life. Therefore, it has been one of most popular research topics in social psychology. The aim of this study is to find out if there is a meaningful relationship between religious orientation and self-monitoring, and to determine the direction of the relationship if it exists. Besides, examining the effect of religious group membership on self-monitoring is (...) another aim of this study. In accordance with this purpose, Religious Orientation Scale and Revised Self-Monitoring Scale are applied to sample group which consists of 437 female and 369 male participants aged16 to 65+ living in Bursa. The results has revealed that there is a meaningful positive correlation between intrinsic religious orientation and self-monitoring. In addition, no meaningful relationship between religious group membership and self-monitoring has been confirmed.Summary: The adaptation process of the human being as a social creature starts in a mother's womb and becomes more complicated in consequence of coming into the world which is full of stimulus. In the beginning, this process has only a physical aspect, but with the inclusion of emotional, cognitive, and social factors over time turns into developmental tasks that people will struggle throughout their lives. The social development involves the process of becoming of the individual as an organic part of the society. As the individual realizes the existence of the other, he/she develops similar patterns of behavior that can be approved by the other. Because the meaningful relationships that form the backbone of social development constitute an important part of the self. Belonging is one of the main needs, that the individual shapes his emotions, actions, and decisions more or less in line with this need in order not to encounter the possibility of social exclusion. While belonging is a universal need for every healthy individual, there are differences between individuals in terms of directing the course of the relationship, role sharing, and using situational clues. Individual differences in how people construct interpersonal processes led Mark Snyder to systematize and theorize the concept of self-monitoring. Self-monitoring is a concept that expresses individuals' control of self-presentation, expressive behavior, and non-verbal emotional expression and their regulation. Accordingly, individuals with a high tendency to shape their behavior according to the context are classified as high self-monitors and those with low tendency are classified as low self-monitors. It can be said that adherence to religion, which is one of the determinants of social behavior, is related to self-monitoring. In this context, the main subject of this study is the relationship between self-monitoring and religiosity. The study aims to examine the effect of intrinsic-extrinsic religiosity on individuals' self-monitoring levels. Besides, as a form of religiosity, to reveal whether religious group religiosity affects self-monitoring, the study examines also self-monitoring levels of individuals belonging to the religious group and those who are not.The sample of the study was selected by a simple random sampling method and it consists of 806 participants aged 16 to 65+ living in Bursa in 2017. 437 (54.2%) of the participants in the research are women and 369 (45.8%) are men. In this study, a relational screening model was used for determining the presence, direction, and degree of the relationship between the variables. The questionnaire technique was preferred as the method of gathering information. The questionnaire was arranged in a way that does not require asking the participant any other questions apart from the questions on the form. The questionnaire form used in this research consists of 43 items. At the beginning of the questionnaire, there is a 9-item personal information form that includes demographic items consisting of age, gender, educational status, marital status, occupation, place of residence, socio-economic status, levels of subjective religious involvement, and religious group membership. For the measurement of self-monitoring, a 12-item "Self-Monitoring Scale", which was developed by Mark Snyder, revised by Richard Lennox and Raymond Wolfe and adapted by İlknur Özalp Türetgen and Sevim Cesur to Turkish (α =.80) was used. For the measurement of religious orientation, a 22-item “Religious Orientation Scale” developed by Gordon Allport and Michael Ross and adapted to Turkish by Fatma Gül Cirhinlioğlu was used (α =.90). Data collected through scales were processed by One Way Variance Analysis (ANOVA), t-Test, Pearson Correlation Analysis, and Simple Linear Regression Analysis and turned into research findings.According to the results of the simple linear correlation analysis conducted to reveal whether there is a relationship between the self-monitoring scores of the participants and the intrinsic religious orientation scores, there is a positive and significant relationship between the variables (r = 0.102, p = 0.004 0.05). The result of the correlation analysis between self-monitoring and the level of subjective religious involvement shows that no significant relationship is found (r = 0.051, p = 0.146> 0.05).This research expected that there was a negative relationship between self-monitoring and intrinsic religious orientation. However, the analyses has not reported anticipated results as addressed in the previous research. Therefore, this study opens the door for asking new questions about the subject. Religious groups, by their very nature, can refer the individual to self-presentation control, obedience, to act as deemed appropriate by the group, to adapt to the group, to change behavior without attitude change, and therefore, to attitude-behavior inconsistency. It can be argued that not only religious groups but, by their nature, all social groups create harmony-oriented pressure on the individual. Therefore, it can be predicted that belonging to a group, in general, may have a significant effect on the level of self-monitoring. The high self-monitoring scores of the participants, whether religious or non-religious group members of this study may have reduced the observability of the difference between the two groups. Therefore, repeating the study on a different sample may produce different results. (shrink)

This essay delineates points of agreement and disagreement between Plato and Nietzsche with respect to the original Heraclitean argument that the underlying dynamic connective structure of the whole is ‘strife’. Also discussed is the issue of how each philosopher understands life itself, as a general process, to be related to the wider processive whole. The paper analyses how the Heraclitean understanding of the natural whole influences each philosopher's interpretation of the political structures of man. The analysis attempts to demonstrate why (...) for Nietzsche, on one hand, the value forms of the traditional polis are more in accord with human nature and nature in toto than is philosophy and why for Plato, on the other hand, when the value forms of the polis are superseded by those of philosophy it is a natural process rather than contrary to nature.

The Black Mirror episode “Arkangel” tells a disturbing story of over-parenting driven by technology. The single mother Marie’s adoption of the Arkangel system has invited overwhelmingly negative moral evaluation from philosophers. But what accounts for the moral failure of a loving and concerned parent? Is it all about her flawed character, or are there situational factors at work? In the article, I first foreground the slipperiness of technology implicated in Albert Borgmann’s notion of the “device paradigm” and Hans Jonas’s analysis (...) of modern technology. Then I analyze the character of the Arkangel system in the light of the two philosophers’ works and show how the technology turns Marie into a failing parent. In the end, I offer tentative answers to the two questions; the answers shall also shed light on the problem of under-parenting driven by digital technology. (shrink)

In this book K. Brad Wray provides a comprehensive survey of the arguments against scientific realism. In addition to presenting logical considerations that undermine the realists' inferences to the likely truth or approximate truth of our theories, he provides a thorough assessment of the evidence from the history of science. He also examines grounds for a defence of anti-realism, including an anti-realist explanation for the success of our current theories, an account of why false theories can be empirically successful, and (...) an explanation for why we should expect radical changes of theory in the future. His arguments are supported and illustrated by cases from the history of science, including a sustained study of the Copernican Revolution, and a study of the revolution in early twentieth century chemistry, when chemists came to classify elements by their atomic number rather than by their atomic weight.

Using medical advances to enhance human athletic, aesthetic, and cognitive performance, rather than to treat disease, has been controversial. Little is known about physicians? experiences, views, and attitudes in this regard. We surveyed a national sample of physicians to determine how often they prescribe enhancements, their views on using medicine for enhancement, and whether they would be willing to prescribe a series of potential interventions that might be considered enhancements. We find that many physicians occasionally prescribe enhancements, but doctors hold (...) nuanced and ambiguous views of these issues. Most express concerns about the potential effects of enhancements on social equity, yet many also believe specific enhancements that are safe and effective should be available but not covered by insurance. These apparently contradictory views might reflect inherent tensions between the values of equity and liberty, which could make crafting coherent social policies on medical enhancements challenging.

The Danish theologian-philosopher K. E. Løgstrup is second in reputation in his homeland only to Søren Kierkegaard. He is best known outside Europe for his _The Ethical Demand_, first published in Danish in 1956 and published in an expanded English translation in 1997. _Beyond the Ethical Demand_ contains excerpts, translated into English for the first time, from the numerous books and essays Løgstrup continued to write throughout his life. In the first essay, he engages the critical response to _The Ethical (...) Demand,_ clarifying, elaborating, or defending his original positions. In the next three essays, he extends his contention that human ethics “demands” that we are concerned for the other by introducing the crucial concept of “sovereign expressions of life.” Like Levinas, Løgstrup saw in the phenomenon of “the other” the ground for his ethics. In his later works he developed this concept of “the sovereign expressions of life,” spontaneous phenomena such as trust, mercy, and sincerity that are inherently other-regarding. The last two essays connect his ethics with political life. Interest in Løgstrup in the English-speaking academic community continues to grow, and these important original sources will be essential tools for scholars exploring the further implications of his ethics and phenomenology. “K. E. Løgstrup’s work undoubtedly made in his time an original contribution to the field of moral philosophy and philosophy of religion. This translation makes extracts from his later publications on moral philosophy accessible to an English-speaking audience. I am again impressed by the depth of his ideas, which are certainly not outdated and still relevant for contemporary debates in moral philosophy.” —_Bert Musschenga, Vrije Universiteit, Amsterdam _ “Making a large part of Knud Løgstrup’s legacy accessible to the English-speaking public is an event of enormous cultural, philosophical and political importance—and we are all in debt to his disciple, Kies van Kooten Niekerk, and the University Press of Notre Dame, for making it happen. Løgstrup, alongside few other giants of 20th Century ethical thought, like Emmanuel Levinas or Hans Jonas, anticipated and articulated all the major challenges and urgent tasks with which the coming century is likely to confront the moral self. Our ethical discourse was all the poorer so far for being barred access to his findings and proposition. This will no longer be the case.” —_Zygmunt Bauman, emeritus, University of Leeds_ “The publication of an English translation of Knut Eljert Løgstrup's later works in ethics provides a wider readership with the opportunity to better understand his important contribution to ethics in the second half of the last century. With his notion of the _Sovereign Expressions of Life_ Løgstrup articulates his rejection of moral atomism that has become influential in recent times. The introduction and annotation by Kees van Kooten Niekerk are very helpful to see how Løgstrup's thought developed beyond _The Ethical Demand.” —__Hans S. Reinders, Vrije Universiteit, Amsterdam_.

This chapter discusses Kuhn’s conception of the history of science by focussing on two respects in which Kuhn is an historicist historian and philosopher of science. I identify two distinct, but related, aspects of historicism in the work of Hegel and show how these are also found in Kuhn’s work. First, Kuhn held tradition to be important for understanding scientific change and that the tradition from which a scientific idea originates must be understood in evaluating that idea. This makes Kuhn (...) a historicist in a sense we may call conservative. Secondly, Kuhn held that there is a pattern to the development of science. In the light of the fact that he held scientific change to be law-like, we can call this second aspect of Kuhn’s historicism determinist. I discuss the relationship of Kuhn’s historicist historiography to the philosophical purposes he had for his history of science, namely to refute a conception of scientific progress as driven towards increasing truth by something like ‘the scientific method’. I argue that while this determinism refutes certain positivist conceptions of scientific change, it also requires internalism—the view that the causes of scientific change come from within science, not from outside. Consequently, Kuhn’s historiography of science contrasts with that implicit in much of post-Kuhnian science studies. (shrink)

Developing the Horizons of the Mind is a comprehensive book on Relational and Contextual Reasoning, a theory of the human mind which powerfully addresses key areas of human conflict such as the ideological conflict between nations, the conflict in close relationships and the conflict between science and religion. K. Helmut Reich provides a clear and accessible introduction to the fresh RCR way of thinking that encourages people to adopt an inclusive rather than an oppositional approach to conflict and problem-solving. Part (...) one outlines the key aspects of RCR theory and supporting empirical data and part two provides examples of its application in the world. RCR provides a stimulating and challenging tool to several disciplines, including philosophy, psychology, religious studies and education, and this book will be a valuable resource for cognitive scientists, psychotherapists, theologians, educators and all those involved in conflict resolution.

Responses to public health emergencies can entail difficult decisions about restricting individual liberties to prevent the spread of disease. The quintessential example is quarantine. While isolating sick patients tends not to provoke much concern, quarantine of healthy people who only might be infected often is controversial. In fact, as the experience with severe acute respiratory syndrome (SARS) shows, the vast majority of those placed under quarantine typically don't become ill. Efforts to enforce involuntary quarantine through military or police powers also (...) can backfire, stoking both panic and disease spread. Yet quarantine is part of a limited arsenal of options when effective treatment or prophylaxis is not available, and some evidence suggests it can be effective, especially when it is voluntary, home-based and accompanied by extensive outreach, communication and education efforts. Even assuming that quarantine is medically effective, however, it still must be ethically justified because it creates harms for many of those affected. Moreover, ethical principles of reciprocity, transparency, non-discrimination and accountability should guide any implementation of quarantine. (shrink)

In this article, we analyze how movement takes part in creating intersubjective meaning. We discuss what Daniel Stern termed ‘affect attunement,’ a primary way of constituting intersubjectivity. Based on an analysis of how movement, meaning-making, vitality affects, and primordial feelings interrelate in affect attunement, we show that primordial feelings and thereby movement play a much greater role in affect attunement than Stern proposed. This makes movement a primary meaning-making modality, indispensable to the development of intersubjectivity. To illustrate the relation between (...) movement and affect attunement in psychological development, we discuss the role of movement in autism. Recent research suggests that differences in movement precede the onset of social-communicative deficits and may be primary to autistic development. Building on the proposed interrelation of movement and primordial feelings in affect attunement, we suggest that autistic movement differences illuminate the vital role played by movement in early intersubjective development.

Through qualitative surveys, a team of law students, law professors, physicians, and residents explored the perceptions of neurology residents towards referral to appropriate legal resources in an academic training program. Respondents reported feeling uncomfortable screening their patients for health-harming legal needs, which many attributed to a lack of training in this area. These findings indicate that neurology residents would benefit from training on screening for social factors that may be impacting their patients’ health.

Recent arguments over whether certain public health interventions should be mandatory raise questions about what counts as a "mandate." A mandate is not the same as a mere recommendation or the standard of practice. At minimum, a mandate should require an active opt-out and there should be some penalty for refusing to abide by it. Over-loose use of the term "mandate" and the easing of opt-out provisions could eventually pose a risk to the gains that truly mandatory public health interventions, (...) such as childhood vaccines, have provided over the last 50 years. Already, confusion about what counts as a mandate, and about what criteria should be used to determine when a public health intervention should be implemented as a mandate, has led to some inappropriate public policy decisions. For instance, by any reasonable criteria, the yearly influenza vaccine should be mandatory for health care workers. To enforce this mandate, those who refuse vaccination should be required to sign a waiver, and patients - especially those at high risk from flu - should be informed when they receive care from unvaccinated practitioners.

A new model for the aether is suggested according to which it is a superfluid state of fermion and antifermion pairs, describable by a macroscopic wave function. The vacuum state of this superfluid pervades the entire universe and may account for the missing matter. The visible matter in the universe appears as excitations from the underlying superfluid vacuum.
