For someone with an outsized influence on a field he helped to create, Dan Callahan was anything but overbearing. Physically compact, thin, and wiry in older age, he spoke at the rapid speed of his mind. Soon after I met him—when I was on the cusp of what would become a year‐long residency at The Hastings Center—I found myself seated in his decidedly quaint living room. Dan told a story that evening, one of many that has stuck in my head. (...) It seemed to encapsulate his moral mindset and, in a way, his broader vision for bioethics. I am sure he has told the story many times to many people, but here it is as I recall it. (shrink)

The WHO, American Academy of Pediatrics and other Western medical bodies currently maintain that all medically unnecessary female genital cutting of minors is categorically a human rights violation, while either tolerating or actively endorsing medically unnecessary male genital cutting of minors, especially in the form of penile circumcision. Given that some forms of female genital cutting, such as ritual pricking or nicking of the clitoral hood, are less severe than penile circumcision, yet are often performed within the same families for (...) similar reasons, it may seem that there is an unjust double standard. Against this view, it is sometimes claimed that while female genital cutting has ‘no health benefits’, male genital cutting has at least some. Is that really the case? And if it is the case, can it justify the disparate treatment of children with different sex characteristics when it comes to protecting their genital integrity? I argue that, even if one accepts the health claims that are sometimes raised in this context, they cannot justify such disparate treatment. Rather, children of all sexes and genders have an equal right to bodily autonomy. This includes the right to decide whether their own ‘private’ anatomy should be exposed to surgical risk, much less permanently altered, for reasons they themselves endorse when they are sufficiently mature.

The primary objective was to review pediatric ethics consultations at a large academic health center over a nine year period, assessing demographics, ethical issues, and consultant intervention. The secondary objective was to describe the evolution of PECs at our institution. This was a retrospective review of Consultation Summary Sheets compiled for PECs at our Academic Health Center between January 2008 and April 2017. There were 165 PECs reviewed during the study period. Most consult requests came from the inpatient setting, with (...) the Pediatric and Neonatal Intensive Care Units being the highest utilizers. Consultation utilization increased over the study period. The most common patient age was less than one year. Physicians were most likely to request consultation. Patient Best Interest, Withholding/Withdrawing of Life Sustaining Therapy, and Provider Moral Distress were ethical issues most commonly identified by the consultants. Making recommendations was the most common consultant intervention. The ethics consultation process evolved over time from informal provider discussions, to a hospital infant care review committee, to a pediatric only consultation service, to a combined adult/pediatric consultation service, with variable levels of salary support for consultants. Ethics consultation requests are growing at our institution. Similarities in identified ethical issues exist between our findings and existing literature, however meaningful comparisons remains elusive secondary to variability in approaches to investigation and reporting. A combined paid/volunteer/trainee ethics consultation service model appears sustainable and real time ethics consultation is feasible using this approach. (shrink)

Historically, laws and policies to criminalize drug use or possession were rooted in explicit racism, and they continue to wreak havoc on certain racialized communities. We are a group of bioethicists, drug experts, legal scholars, criminal justice researchers, sociologists, psychologists, and other allied professionals who have come together in support of a policy proposal that is evidence-based and ethically recommended. We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation. We (...) also call for criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs to be expunged, and for those currently serving time for these offenses to be released. In effect, we call for an end to the “war on drugs.”. (shrink)

Our article identifies and describes the metaphoric fallacy to a deductive inference (MFDI) that is an example of incorrect reasoning along the lines of the false analogy fallacy. The MFDI proceeds from informal semantical (metaphorical) claims to a supposedly formally deductive and necessary inference. We charge that such an inference is invalid. We provide three examples of the MFDI to demonstrate the structure of this invalid form of reasoning. Our goal is to contribute to the set of known informal fallacies.

If you grade enough papers, you will find some consistent pitfalls, especially in the writing of students who are coming to philosophy for the first time. I wrote up the following tips a couple of years ago when I was a teaching assistant for an introductory philosophy class at Yale led by Daniel Greco called ‘Problems in Philosophy’. The tips were intended, then, for college students, many of them right out of high school, and most of whom had never written (...) a philosophy paper before. So the focus is on clarity and mastering the basics. With that in mind, I hope you will find these tips helpful for teaching or writing in philosophy. (shrink)

This paper explores an emerging sub-field of both empirical bioethics and experimental philosophy, which has been called “experimental philosophical bioethics” (bioxphi). As an empirical discipline, bioxphi adopts the methods of experimental moral psychology and cognitive science; it does so to make sense of the eliciting factors and underlying cognitive processes that shape people’s moral judgments, particularly about real-world matters of bioethical concern. Yet, as a normative discipline situated within the broader field of bioethics, it also aims to contribute to substantive (...) ethical questions about what should be done in a given context. What are some of the ways in which this aim has been pursued? In this paper, we employ a case study approach to examine and critically evaluate four strategies from the recent literature by which scholars in bioxphi have leveraged empirical data in the service of normative arguments.

Male circumcision—partial or total removal of the penile prepuce—has been proposed as a public health measure in Sub-Saharan Africa, based on the results of three randomized control trials showing a relative risk reduction of approximately 60 per cent for voluntary, adult male circumcision against female-to-male human immunodeficiency virus transmission in that context. More recently, long-time advocates of infant male circumcision have argued that these findings justify involuntary circumcision of babies and children in dissimilar public health environments, such as the USA, (...) Australasia and Europe. In this article, we take a close look at the necessary ethical and empirical steps that would be needed to bridge the gap between the African RCTs and responsible public health policy in developed countries. In the course of doing so, we discuss some of the main disagreements about the moral permissibility of performing a nontherapeutic surgery on a child to benefit potential future sexual partners of his. In this context, we raise concerns not only about weaknesses in the available evidence concerning such claims of benefit, but also about a child’s moral interest in future autonomy and the preservation of his bodily integrity. We conclude that circumcision of minors in developed countries on public health grounds is much harder to justify than proponents of the surgery suggest. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Moral Traditions: An Introduction to World Religious Ethics, and: Understanding Religious Ethics, and: Moral Struggle and Religious Ethics: On the Person as Classic in Comparative Theological ContextsBrian D.

Comparative Theological Contexts David A. Clairmont Malden, Mass.: Wiley-Blackwell, 2011. 245 pp. $99.95These three texts each make significant contributions to comparative religious ethics, a relatively recent discipline that reflects the rise of religious pluralism and globalization. Taken together, these books raise questions about what comparative religious ethics is, how it should be done, and why it should be done. What makes comparative religious ethics “comparative” and to what extent can comparative religious ethics be made genuinely “theological”?Mari Rapela Heidt, who holds a PhD in theological ethics from Marquette University and currently lectures in the religious studies department at the University of Dayton, has written a well-organized and highly accessible introduction to the ethics of the world religions for beginning undergraduate students. Each of the main chapters in her book surveys a major world religion (Hinduism, Buddhism, Judaism, Christianity, Islam, and the Chinese moral tradition) through four lenses: a brief review of the tradition; the moral world of the religion; values, principles, or virtues in the tradition; and the religious tradition on a particular moral issue (e.g., Hinduism on abortion, Buddhism on wealth and poverty, Judaism on the environment, Christianity on war and peace, Islam on men and women, and China’s one-child [End Page 202] policy). The book also includes opening chapters that introduce students to the study of ethics and religious ethics; a final chapter on additional religious moral traditions (Sikhism, Jainism, Bahá’í, and Shinto); sidebars highlighting major religious figures, texts, or events (e.g., Gandhi, Thich Nhat Hanh, Elie Wiesel, the Charter of Medina, and the Cultural Revolution); and discussion questions, bibliography (including visual media), footnotes, a glossary, and an index.Although this book briefly discusses the discipline of comparative religious ethics and some of its descriptive and conceptual methods in its opening chapters, its broad scope and concise treatment mean that the actual task of comparing the similarities and differences in the ethics of the world religions is kept to a minimum. The few detailed comparisons that are made focus largely on Hindu, Buddhist, and Christian understandings of the concepts of reincarnation (29, 34, 64), dharma (18–19, 23–24, 34–35, 64), karma (18–19, 21–23, 35–36, 64), and ahimsa (25–27, 38, 70–71). While the main chapters are organized in a way that facilitates comparison, and discussion questions are included that invite students to observe similarities and differences, the book would be strengthened by giving greater attention to comparison throughout and adding a concluding chapter that summarizes its comparative content. It ends somewhat abruptly with a discussion of the Shinto moral tradition.Charles Mathewes, associate professor of religious studies at the University of Virginia, has written a book that, while limited to Judaism, Christianity, and Islam, achieves much greater comparative sophistication. The text is based on a course he has taught for more than ten years called “Religious Ethics and Moral Problems,” and it bears the marks of a seasoned teacher whose primary audience is advanced undergraduate students, both religious and secular. Mathewes writes from a Protestant Christian perspective “having a strong apocalyptic dimension which is focused on the next life,” acknowledging that Roman Catholics and Eastern Orthodox may find his views “odd or confused” (53). Part 1 discusses the relationship between God and morality and provides an overview of the ethics of each of the three Abrahamic religions. Parts 2 and 3 then examine not only the moral positions but “the arguments animating the traditions” (3) on a wide range of personal and social matters (e.g., friendship, sexuality, marriage and family, lying, forgiveness, capital punishment, war, and the environment). Part 4 turns to the even more ordinary topics of labor, leisure, and life and the more... (shrink)

The ‘born this way’ movement for sexual orientation minority rights is premised on the view that sexual orientation is something that can neither be chosen nor changed. Indeed, current sexual orientation change efforts appear to be both harmful and ineffective. But what if ‘high-tech conversion therapies’ are invented in the future that are effective at changing sexual orientation? The conceptual basis for the movement would collapse. In this chapter, we argue that the threat of HCT should be taken seriously, motivating (...) a change in tactics for proponents of sexual orientation minority rights. We also discuss some of the practical-ethical and public-policy issues surrounding HCT, in case the technology is one day developed. (shrink)

When making substituted judgments for incapacitated patients, surrogates often struggle to guess what the patient would want if they had capacity. Surrogates may also agonize over having the (sole) responsibility of making such a determination. To address such concerns, a Patient Preference Predictor (PPP) has been proposed that would use an algorithm to infer the treatment preferences of individual patients from population-level data about the known preferences of people with similar demographic characteristics. However, critics have suggested that even if such (...) a PPP were more accurate, on average, than human surrogates in identifying patient preferences, the proposed algorithm would nevertheless fail to respect the patient’s (former) autonomy since it draws on the ‘wrong’ kind of data: namely, data that are not specific to the individual patient and which therefore may not reflect their actual values, or their reasons for having the preferences they do. Taking such criticisms on board, we here propose a new approach: the Personalized Patient Preference Predictor (P4). The P4 is based on recent advances in machine learning, which allow technologies including large language models to be more cheaply and efficiently ‘fine-tuned’ on person-specific data. The P4, unlike the PPP, would be able to infer an individual patient’s preferences from material (e.g., prior treatment decisions) that is in fact specific to them. Thus, we argue, in addition to being potentially more accurate at the individual level than the previously proposed PPP, the predictions of a P4 would also more directly reflect each patient’s own reasons and values. In this article, we review recent discoveries in artificial intelligence research that suggest a P4 is technically feasible, and argue that, if it is developed and appropriately deployed, it should assuage some of the main autonomy-based concerns of critics of the original PPP. We then consider various objections to our proposal and offer some tentative replies. (shrink)

The current study investigated the relationship of the Dark Triad with peer reporting, which occurs when an employee informs management that another coworker has engaged in counterproductive work behavior (CWB). We hypothesized that low organizational commitment would strengthen the negative relationships between each Dark Triad trait and peer reporting. Data from 281 employees suggested that low organizational commitment indeed strengthened the negative relationships between (a) narcissism and the base rate of peer reporting CWBs and (b) psychopathy and the base rate (...) of peer reporting CWBs. Our findings thus extended Dark Triad research to the topic of peer reporting. (shrink)

This volume provides an analysis of divine aseity in Karl Barth's thought and appreciates the vital role that this doctrine can play in contemporary theology. Brian D. Asbill begins by setting the general theological context, first through a broad sketch of the development of Barth's understanding of the relationship between the life of God pro nobis (pronobeity) and a se (aseity), and secondly through the examination of the basic theological convictions that guide his approach to the divine being in (...) Church Dogmatics II/1. The second section, 'The Love and Freedom of God', turns to the dialectical pairings which guide Barth's accounts of the divine reality in his earliest dogmatic cycle (The Göttingen Dogmatics §§16-7) as well as in his most mature treatment (Church Dogmatics §§28-31). Particular attention is given to how these themes arise from revelation and relate to one another. In the final section, 'The Aseity of God', Asbill identifies this doctrine's basic features and primary functions. Divine aseity is characterized as the self-demonstration and self-movement of God's life, a trinitarian and entirely unique reality, a primarily positive and dynamic concept, and the manner and readiness of God's love for creatures. Divine aseity is said to indicate God's lordship in the act of self-binding, God's uniqueness in the act of self-revelation, and God's sufficiency in the act of self-giving. (shrink)

In this paper I ask how Timaeus explains change within the trianglebased part of his cosmos. Two common views are that change among physical items is somehow caused or enabled by either the forms or the demiurge. I argue for a competing view, on which the physical items are capable of bringing about change by themselves, prior to the intervention of the demiurge, and prior to their being turned into imitations of the forms. I outline three problems for the view (...) that physical things depend on the forms for their causal powers, and show how the view I propose solves each. I then add further arguments for my view, based on (a) statements by Timaeus that seem to favor my view directly, (b) implications of Timaeus’ positions that favor the view, and (c) Timaeus’ explanatory practice in the second half of his speech.

“Love hurts”—as the saying goes—and a certain amount of pain and difficulty in intimate relationships is unavoidable. Sometimes it may even be beneficial, since adversity can lead to personal growth, self-discovery, and a range of other components of a life well-lived. But other times, love can be downright dangerous. It may bind a spouse to her domestic abuser, draw an unscrupulous adult toward sexual involvement with a child, put someone under the insidious spell of a cult leader, and even inspire (...) jealousy-fueled homicide. How might these perilous devotions be diminished? The ancients thought that treatments such as phlebotomy, exercise, or bloodletting could “cure” an individual of love. But modern neuroscience and emerging developments in psychopharmacology open up a range of possible interventions that might actually work. These developments raise profound moral questions about the potential uses—and misuses—of such anti-love biotechnology. In this article, we describe a number of prospective love-diminishing interventions, and offer a preliminary ethical framework for dealing with them responsibly should they arise. (shrink)

Background: Recent literature on addiction and judgments about the characteristics of agents has focused on the implications of adopting a ‘brain disease’ versus ‘moral weakness’ model of addiction. Typically, such judgments have to do with what capacities an agent has (e.g., the ability to abstain from substance use). Much less work, however, has been conducted on the relationship between addiction and judgments about an agent’s identity, including whether or to what extent an individual is seen as the same person after (...) becoming addicted. Methods: We conducted a series of vignette-based experiments (total N = 3,620) to assess lay attitudes concerning addiction and identity persistence, systematically manipulating key characteristics of agents and their drug of addiction. Conclusions: In Study 1, we found that US participants judged an agent who became addicted to drugs as being closer to ‘a completely different person’ than ‘completely the same person’ as the agent who existed prior to the addiction. In Studies 2-6, we investigated the intuitive basis for this result, finding that lay judgments of altered identity as a consequence of drug use and addiction are driven primarily by perceived negative changes in the moral character of drug users, who are seen as having deviated from their good true selves.

There is an ongoing public debate about sex, gender and identity that is often quite heated. This is an edited transcript of an informal lecture I recorded in 2019 to serve as a friendly guide to these complex issues.

Pharmaceuticals or other emerging technologies could be used to enhance (or diminish) feelings of lust, attraction, and attachment in adult romantic partnerships. While such interventions could conceivably be used to promote individual (and couple) well-being, their widespread development and/or adoption might lead to “medicalization” of human love and heartache—for some, a source of serious concern. In this essay, we argue that the “medicalization of love” need not necessarily be problematic, on balance, but could plausibly be expected to have either good (...) or bad consequences depending upon how it unfolds. By anticipating some of the specific ways in which these technologies could yield unwanted outcomes, bioethicists and others can help direct the course of love’s “medicalization”—should it happen to occur—more toward the “good” side than the “bad.”.

Ethical dilemmas arise when one must decide between conflicting ethical imperatives. One potential ethical dilemma is a manager’s decision of whether to engage in corporate social responsibility activities. This decision could pit the ethical imperative of honoring unwritten obligations to society against the ethical imperative of honoring contractual obligations to the firm. However, CSR activities might only be a minor ethical dilemma or none at all if they simultaneously benefit the firm and society. To examine this I test the association (...) between future-period employee productivity and current-period use of one type of CSR activity: employee volunteer programs. I use a unique sample of 1428 firm-years, hand-collected from sustainability reports of 373 firms. I find evidence that the current-period use of an employee volunteer program has a positive association with future-period employee productivity. I find this result in future periods up to 6 years after a firm uses an employee volunteer program. I also find a positive association between incentives that focus CEOs’ attention on long-term firm outcomes and more extensive employee volunteer programs. (shrink)

An inclusive survey from Frederick Douglass to the voices of Black Lives Matter.

Volume 20, Issue 8, August 2020, Page 72-75.

This thesis is about toleration as a modality of citizenship for pluralistic societies. Its central argument is that the current dissatisfaction with "mere" toleration which we find so broadly represented in our public and scholarly cultures is based on an underestimation of the capacities and attitudes that toleration entails. The liberal recasting of toleration, sophisticated and indeed invaluable though it is abets this devaluation by focusing too exclusively on public justification and on the Lockean stream of the tradition from which (...) we draw. ;The present thesis begins by tracing some of the difficulties facing the Rawlsian and Habermasian projects if we accept a vivid picture of the pluralisms amidst which we live. It then sketches the central features of a complementary tradition of toleration as it flows to us through the works of Montaigne, William James, Mikhail Bakhtin and others. An attempt is made to show where the resources drawn from this tradition might fit in to a theory of citizenship given reasonable Rawlsian qualms about "thick" public conceptions and given the fissiparous nature of a civil society like ours. The thesis ends with a pair of empirically oriented chapters which show ways in which we could conceive a praxis of toleration which might respond to the issues raised in the earlier sections of the work.

Over the past few years, we and our colleagues have been exploring the ethical implications of what we call “love drugs” and “anti-love drugs.” We use these terms informally to refer to “current, near-future, and more speculative distant-future technologies that would enhance or diminish, respectively, the romantic bond between couples engaged in a relationship”. In a recent “qualified defense” of our work, Andrew Andrew McGee suggests that, if we would only stop using the word “love” so expansively, our ethical proposals (...) might gain more traction. Specifically, he argues that “many of the putative instances of love” that we discuss in our papers “are not in fact... (shrink)

The enhancement debate in neuroscience and biomedical ethics tends to focus on the augmentation of certain capacities or functions: memory, learning, attention, and the like. Typically, the point of contention is whether these augmentative enhancements should be considered permissible for individuals with no particular “medical” disadvantage along any of the dimensions of interest. Less frequently addressed in the literature, however, is the fact that sometimes the _diminishment_ of a capacity or function, under the right set of circumstances, could plausibly contribute (...) to an individual's overall well-being: more is not always better, and sometimes less is more. Such cases may be especially likely, we suggest, when trade-offs in our modern environment have shifted since the environment of evolutionary adaptation. In this article, we introduce the notion of “diminishment as enhancement” and go on to defend a _welfarist_ conception of enhancement. We show how this conception resolves a number of definitional ambiguities in the enhancement literature, and we suggest that it can provide a useful framework for thinking about the use of emerging neurotechnologies to promote human flourishing.

The moral enhancement (or bioenhancement) debate seems stuck in a dilemma. On the one hand, the more radical proposals, while certainly novel and interesting, seem unlikely to be feasible in practice, or if technically feasible then most likely imprudent. But on the other hand, the more sensible proposals – sensible in the sense of being both practically achievable and more plausibly ethically justifiable – can be rather hard to distinguish from both traditional forms of moral enhancement, such as non-drug-mediated social (...) or moral education, and non-moral forms of bioenhancement, such as smart-drug style cognitive enhancement. In this essay, I argue that bioethicists have paid insufficient attention to an alternative form of moral bioenhancement – or at least a likely candidate – that falls somewhere between these two extremes, namely the (appropriately qualified) use of certain psychedelic drugs.

In this chapter, we introduce the notion of “moral neuroenhancement,” offering a novel definition as well as spelling out three conditions under which we expect that such neuroenhancement would be most likely to be permissible (or even desirable). Furthermore, we draw a distinction between first-order moral capacities, which we suggest are less promising targets for neurointervention, and second-order moral capacities, which we suggest are more promising. We conclude by discussing concerns that moral neuroenhancement might restrict freedom or otherwise “misfire,” and (...) argue that these concerns are not as damning as they may seem at first.

Frederick offers a critique of my writing tips aimed at undergraduate students coming to philosophy – and in many cases, essay writing – for the first time Frederick claims that most of my tips are good tips but characterizes two of them as bad tips, as follows: Bad tip 1. Be very careful about making any universal claims. Such a claim can be refuted by just a single counterexample. Do not leave yourself open to such refutation. Make a universal claim (...) only if you are sure that there are no counterexamples. Bad tip 2. Pick a smaller, more narrow thesis and argue for it thoroughly rather than a more ambitious thesis for which you argue less thoroughly. (shrink)

Cramer et al. make a good case for reconceptualizing comorbid psychopathologies in terms of complex network theory. We suggest the need for an extension of their network model to include reference to latent causes. We also draw attention to a neglected approach to theory appraisal that might usefully be incorporated into the methodology of network theory.

Our understanding of the neurochemical bases of human love and attachment, as well as of the genetic, epigenetic, hormonal, and experiential factors that conspire to shape an individual's sexual orientation, is increasing exponentially. This research raises the vexing possibility that we may one day be equipped to modify such variables directly, allowing for the creation of “high-tech” conversion therapies or other suspect interventions. In this article, we discuss the ethics surrounding such a possibility, and call for the development of legal (...) and procedural safeguards for protecting vulnerable children from the application of such technology. We also consider the more difficult case of voluntary, adult “conversion” and argue that in rare cases, such attempts might be permissible under strict conditions. (shrink)

Insight problem solving is hindered by automated verbal–conceptual processes. Because mindfulness meditation training aims at “nonconceptual awareness” which involves a reduced influence of habitual verbal–conceptual processes on the interpretation of ongoing experience, mindfulness may facilitate insight problem solving. This hypothesis was examined across two studies . Participants in both studies completed a measure of trait mindfulness and a series of insight and noninsight problems. Further, participants in Study 2 completed measures of positive affect and a mindfulness or control training. The (...) results indicated that trait mindfulness predicts better insight but not noninsight problem solving , this relation is maintained when controlling for positive affect , mindfulness training improves insight but not noninsight problem solving and this improvement is partially mediated by state mindfulness . These findings are the first to document a direct relation between mindfulness and creativity. (shrink)

This book applies a range of ideas about scientific discovery found in contemporary philosophy of science to psychology and related behavioral sciences. In doing so, it aims to advance our understanding of a host of important methodological ideas as they apply to those sciences. A philosophy of local scientific realism is adopted in favor of traditional accounts that are thought to apply to all sciences. As part of this philosophy, the implications of a commitment to philosophical naturalism are spelt out, (...) and a correspondence theory of truth is defended by showing how it helps explain various features of scientific practice. The central chapter of the book presents a broad theory of scientific method that comprises the detection of empirical phenomena and their subsequent understanding by constructing explanatory theories through the use of abductive methods. This theory of scientific method is then used as a framework to reconstruct the well-known qualitative method of grounded theory, and to present a systematic perspective on clinical reasoning and case formulation. Relatedly, an abductive or explanationist understanding of methods is employed to evaluate the knowledge credentials of evolutionary psychology. In addition, the conceptual and methodological foundations of a variety of quantitative methods are examined. Exploratory factor analysis and tests of statistical significance are given special attention. (shrink)
