Equality and identity. Bulletin of Symbolic Logic. 19 (2013) 255-6. (Coauthor: Anthony Ramnauth) Also see https://www.academia.edu/s/a6bf02aaab This article uses ‘equals’ [‘is equal to’] and ‘is’ [‘is identical to’, ‘is one and the same as’] as they are used in ordinary exact English. In a logically perfect language the oxymoron ‘the numbers 3 and 2+1 are the same number’ could not be said. Likewise, ‘the number 3 and the number 2+1 are one number’ is just as bad from a logical point (...) of view. In normal English these two sentences are idiomatically taken to express the true proposition that ‘the number 3 is the number 2+1’. Another idiomatic convention that interferes with clarity about equality and identity occurs in discussion of numbers: it is usual to write ‘3 equals 2+1’ when “3 is 2+1” is meant. When ‘3 equals 2+1’ is written there is a suggestion that 3 is not exactly the same number as 2+1 but that they merely have the same value. This becomes clear when we say that two of the sides of a triangle are equal if the two angles they subtend are equal or have the same measure. -/- Acknowledgements: Robert Barnes, Mark Brown, Jack Foran, Ivor Grattan-Guinness, Forest Hansen, David Hitchcock, Spaulding Hoffman, Calvin Jongsma, Justin Legault, Joaquin Miller, Tania Miller, and Wyman Park. -/- ► JOHN CORCORAN AND ANTHONY RAMNAUTH, Equality and identity. Philosophy, University at Buffalo, Buffalo, NY 14260-4150, USA E-mail: corcoran@buffalo.edu The two halves of one line are equal but not identical [one and the same]. Otherwise the line would have only one half! Every line equals infinitely many other lines, but no line is [identical to] any other line—taking ‘identical’ strictly here and below. Knowing that two lines equaling a third are equal is useful; the condition “two lines equaling a third” often holds. In fact any two sides of an equilateral triangle is equal to the remaining side! But could knowing that two lines being [identical to] a third are identical be useful? The antecedent condition “two things identical to a third” never holds, nor does the consequent condition “two things being identical”. If two things were identical to a third, they would be the third and thus not be two things but only one. The plural predicate ‘are equal’ as in ‘All diameters of a given circle are equal’ is useful and natural. ‘Are identical’ as in ‘All centers of a given circle are identical’ is awkward or worse; it suggests that a circle has multiple centers. Substituting equals for equals [replacing one of two equals by the other] makes sense. Substituting identicals for identicals is empty—a thing is identical only to itself; substituting one thing for itself leaves that thing alone, does nothing. There are as many types of equality as magnitudes: angles, lines, planes, solids, times, etc. Each admits unit magnitudes. And each such equality analyzes as identity of magnitude: two lines are equal [in length] if the one’s length is identical to the other’s. Tarski [1] hardly mentioned equality-identity distinctions (pp. 54-63). His discussion begins: -/- Among the logical concepts […], the concept of IDENTITY or EQUALITY […] has the greatest importance. -/- Not until page 62 is there an equality-identity distinction. His only “notion of equality”, if such it is, is geometrical congruence—having the same size and shape—an equivalence relation not admitting any unit. Does anyone but Tarski ever say ‘this triangle is equal to that’ to mean that the first is congruent to that? What would motivate him to say such a thing? This lecture treats the history and philosophy of equality-identity distinctions. [1] ALFRED TARSKI, Introduction to Logic, Dover, New York, 1995. [This is expanded from the printed abstract.] .

The discipline of mathematics has not been spared the sweeping critique of postmodernism. Is mathematical theory true for all time, or are mathematical constructs in fact fallible? This fascinating book examines the tensions that have arisen between modern and postmodern views of mathematics, explores alternative theories of mathematical truth, explains why the issues are important, and shows how a Christian perspective makes a difference.

BackgroundOur human societies and certainly also (bio) medicine are more and more permeated with technology. There seems to be an increasing awareness among bioethicists that an effective and comprehensive approach to ethically guide these emerging biomedical innovations into society is needed. Such an approach has not been spelled out yet for bioethics, while there are frequent calls for ethical guidance of biomedical innovation, also by biomedical researchers themselves. New and emerging biotechnologies require anticipation of possible effects and implications, meaning the (...) scope is not evaluative after a technology has been fully developed or about hypothetical technologies, but real-time for a real biotechnology.Main textIn this paper we aim to substantiate and discuss six ingredients that we increasingly see adopted by ethicists and that together constitute “ethics parallel research”. This approach allows to fulfil two aims: guiding the development process of technologies in biomedicine and providing input for the normative evaluation of such technologies. The six ingredients of ethics parallel research are: (1) disentangling wicked problems, (2) upstream or midstream ethical analysis, (3) ethics from within, (4) inclusion of empirical research, (5) public participation and (6) mapping societal impacts, including hard and soft impacts. We will draw on gene editing, organoid technology and artificial intelligence as examples to illustrate these six ingredients.ConclusionEthics parallel research brings together these ingredients to ethically analyse and proactively or parallel guide technological development. It widens the roles and judgements from the ethicist to a more anticipatory and constructively guiding role. Ethics parallel research is characterised by a constructive, rather than a purely critical perspective, it focusses on developing best-practices rather than outlining worst practice, and draws on insights from social sciences and philosophy of technology.

Dementia is highly prevalent and incurable. The participation of dementia patients in clinical research is indispensable if we want to find an effective treatment for dementia. However, one of the primary challenges in dementia research is the patients’ gradual loss of the capacity to consent. Patients with dementia are characterized by the fact that, at an earlier stage of their life, they were able to give their consent to participation in research. Therefore, the phase when patients are still competent to (...) decide offers a valuable opportunity to authorize research, by using an advance research directive. Yet, the use of ARDs as an authorization for research participation remains controversial. In this paper we discuss the role of autonomous decision-making and the protection of incompetent research subjects. We will show why ARDs are a morally defensible basis for the inclusion of this population in biomedical research and that the use of ARDs is compatible with the protection of incompetent research subjects.

The authors of the paper ‘Advance euthanasia directives: a controversial case and its ethical implications’ articulate concerns and reasons with regard to the conduct of euthanasia in persons with dementia based on advance directives. While we agree on the conclusion that there needs to be more attention for such directives in the preparation phase, we disagree with the reasons provided by the authors to support their conclusions. We will outline two concerns with their reasoning by drawing on empirical research and (...) by providing reasons that contradict their assumptions about competence of people with dementia and the importance of happiness in reasoning about advance directives of people with dementia. We will draw attention to the important normative questions that have been overstepped in their paper, and we will outline why further research is required. (shrink)

Healthcare collectives, such as patient organizations, advocacy groups, disability organizations, professional associations, industry advocates, social movements, and health consumer organizations have been increasingly involved in healthcare policymaking. Such collectives are based on the idea that individual interests can be aggregated into collective interests by participation, deliberation, and representation. The topic of collectivity in healthcare, more specifically collective representation, has only rarely been addressed in bioethics. This symposium, entitled: “Collective Representation in Healthcare Policy” of the Journal of Bioethical Inquiry draws attention (...) to this understudied topic from a variety of disciplines, within a variety of socio-cultural contexts. We draw attention to important ethical, cultural, and social questions, and into the practices, justifications for, and implications of collective representation of patients in healthcare policy.

Children and adults with dementia are vulnerable populations. Both groups are also relatively seldom included in biomedical research. However, including them in clinical trials is necessary, since both groups are in need of scientific innovation and new therapies. Their dependence and limited decision-making capacities increase their vulnerability, necessitating extra precautions when including them in clinical trials. Beside these similarities there are also many differences between the groups. The most obvious one is that children have an entire life ahead of them (...) and will become persons with certain ideals and preferences, while adults with dementia have lived a life in which they have expressed their ideals and preferences. Some of the available research guidelines recognize these differences, setting one list of specific requirements for groups of incapacitated adults and another list for children. Other documents, however, do not differentiate and only set requirements for subjects unable to consent as a single category of subjects. In this article we analyse to what extent the similarities and differences between the two groups are represented in legal documents and ethical guidelines. The article presents an overview and an analysis of the requirements for doing research with children and dementia patients. We conclude with suggestions about how to better incorporate the morally relevant aspects of these two groups in legislation and ethical guidelines. (shrink)

Dementia is highly prevalent and up until now, still incurable. If we may believe the narrative that is currently dominant in dementia research, in the future we will not have to suffer from dementia anymore, as there will be a simple techno-fix solution. It is just a matter of time before we can solve the growing public health problem of dementia. In this paper we take a critical stance towards overly positive narratives of techno-fixes by placing our empirical analysis of (...) dementia research protocols and political statements in a framework of technology assessment. From this perspective, it becomes obvious that a techno-fix is just one of many ways to approach societal problems and more importantly that technologies are way less perfect than they are presented. We will argue that this narrow scope, which focusses on the usual suspects for solving illnesses, reduces dementia to organismic aspects, and may be counterproductive in finding a cure for dementia. We conclude with outlining how the narrow scope can be balanced with other narratives and why we should have a reasonable scepticism towards the usual suspects. (shrink)

In their paper ‘Responsibility, second opinions and peer-disagreement: ethical and epistemological challenges of using AI in clinical diagnostic contexts’, Kempt and Nagel discuss the use of medical AI systems and the resulting need for second opinions by human physicians, when physicians and AI disagree, which they call the rule of disagreement.1 The authors defend RoD based on three premises: First, they argue that in cases of disagreement in medical practice, there is an increased burden of proof for the physician in (...) charge, to defend why the opposing view is adopted or overridden. This burden for justification can be understood as an increased responsibility. In contrast, such burden does allegedly not arise, when physicians agree in their judgement. Second, in those medical contexts where humans collaborate with humans such justification can be provided, since human experts can discuss the evidence and reasons that have led them to their judgement, through which the sources of disagreement can be found and a justified decision can be made by the physician in charge. Third, unlike human-to-human collaboration, such communicative exchange is not possible with an AI system. Due to AI’s opacity, the physician in charge has no means of illuminating why the AI disagrees. Conclusively, the authors propose RoD as a solution. RoD suggests that a second human expert should be consulted for advise in cases of human–AI disagreement. Once AI systems become more widespread in clinical practice, it can be expected that such type of disagreement occurs more frequently. AI, after all, is being implemented, because it promises, among others, higher accuracy, which implies that some abnormalities will be detected that the physician would have missed.2 Hence, it is laudable to discuss the moral implications of ….

In order to discover an effective treatment for dementia it is necessary to include dementia patients in clinical research trials. Dementia patients face an increased risk to lose the capacity to consent to research participation, and research possibilities with incompetent participants are legally strictly limited. One solution is for patients to consent to research through an advance research directive whilst still competent. In order to explore whether such a directive would be useful and valuable in practice we conducted a qualitative (...) study. We explored the opinions and arguments of researchers in the field of dementia, aiming to map the possibilities and constraints of ARDs. It was argued that a positive ARD could be valuable to discuss research participation with proxies, and patients with a negative ARD will be excluded from research trials. However, it is argued that an ARD cannot replace the informed consent procedure, and in practice proxy dissent will overrule written consent. The practical use of these directives is thus limited, as most researchers will not comply with positive directives. (shrink)

The idea that dementia is essentially a return to childhood and those affected must somehow be similar to children constitutes a deeply rooted and pervasive cultural trope. While such tropes may be helpful in making sense of an otherwise elusive and inscrutable state, they can at the same time promote inadequate understandings of dementia and hence also influence our attitudes and behaviour towards those affected in several problematic ways. In the present work, we provide a detailed account of the origins (...) and implications of the idea that people with dementia are somehow similar to children. In order to spell out the normative significance of this trope and to analyse its shortcomings, we will rely on a life‐course perspective. We will point out that the second‐childhood trope does not do justice to the particularities of the life phases of both children and people with dementia. This lack of biographical sensitivity brings about undignified treatment of and harm to those who have previously lived more autonomous lives. In conclusion, we will argue that people with dementia should not be equated with children as they are at a different point in their lives. This critical analysis of the second‐childhood trope shows the usefulness of a culturally and biographically sensitive theoretical framework for bioethical reflection. In particular, it provides reasons to reject infantilizing attitudes and behaviours and instead take seriously the personality, values and preferences shaped throughout the course of an individual's life.

The use of black box algorithms in medicine has raised scholarly concerns due to their opaqueness and lack of trustworthiness. Concerns about potential bias, accountability and responsibility, patient autonomy and compromised trust transpire with black box algorithms. These worries connect epistemic concerns with normative issues. In this paper, we outline that black box algorithms are less problematic for epistemic reasons than many scholars seem to believe. By outlining that more transparency in algorithms is not always necessary, and by explaining that (...) computational processes are indeed methodologically opaque to humans, we argue that the reliability of algorithms provides reasons for trusting the outcomes of medical artificial intelligence. To this end, we explain how computational reliabilism, which does not require transparency and supports the reliability of algorithms, justifies the belief that results of medical AI are to be trusted. We also argue that several ethical concerns remain with black box algorithms, even when the results are trustworthy. Having justified knowledge from reliable indicators is, therefore, necessary but not sufficient for normatively justifying physicians to act. This means that deliberation about the results of reliable algorithms is required to find out what is a desirable action. Thus understood, we argue that such challenges should not dismiss the use of black box algorithms altogether but should inform the way in which these algorithms are designed and implemented. When physicians are trained to acquire the necessary skills and expertise, and collaborate with medical informatics and data scientists, black box algorithms can contribute to improving medical care.

That’s Bill Calvin, whose brain is worthy of study in its own right. Technically, he’s a theoretical neurophysiologist and affiliate professor of psychiatry and behavioral sciences at the University of Washington.

As I sat down to interview Calvin in his book-lined Seattle home last Fall, I recalled the comments of someone who (...) had come to GBN to hear Calvin speak. He said that he didn’t know—or care—what Calvin was going to talk about because everything that Bill Calvin said was not only interesting, but worth learning about.

Mobile health is rapidly being implemented and changing our ways of doing, understanding and organising healthcare. mHealth includes wearable devices as well as apps that track fitness, offer wellness programmes or provide tools to manage chronic conditions. According to industry and policy makers, these systems offer efficient and cost-effective solutions for disease prevention and self-management. While this development raises many ethically relevant questions, so far mHealth has received only little attention in medical ethics. This paper provides an overview of bioethical (...) issues raised by mHealth and aims to draw scholarly attention to the ethical significance of its promises and challenges. We show that the overly positive promises of mHealth need to be nuanced and their desirability critically assessed. Finally, we offer suggestions to bioethicists to engage with this emerging trend in healthcare to develop mHealth to its best potential in a morally sound way. (shrink)

Abstract:Calvin Warren talks about Heidegger's influence on Afropessimism, and about the philosophical significance of the Harlem Renaissance.

BackgroundGene drive technologies (GDTs) promote the rapid spread of a particular genetic element within a population of non-human organisms. Potential applications of GDTs include the control of insect vectors, invasive species and agricultural pests. Whether, and if so, under what conditions, GDTs should be deployed is hotly debated. Although broad stances in this debate have been described, the convictions that inform the moral views of the experts shaping these technologies and related policies have not been examined in depth in the (...) academic literature.MethodsIn this qualitative study, we interviewed GDT experts (n = 33) from different disciplines to identify and better understand their moral views regarding these technologies. The pseudonymized transcripts were analyzed thematically.ResultsThe respondents’ moral views were principally influenced by their attitudes towards (1) the uncertainty related to GDTs; (2) the alternatives to which they should be compared; and (3) the role humans should have in nature. Respondents agreed there is epistemic uncertainty related to GDTs, identified similar knowledge gaps, and stressed the importance of realistic expectations in discussions on GDTs. They disagreed about whether uncertainty provides a rationale to refrain from field trials (‘risks of intervention’ stance) or to proceed with phased testing to obtain more knowledge given the harms of the status quo (‘risks of non-intervention’ stance). With regards to alternatives to tackle vector-borne diseases, invasive species and agricultural pests, respondents disagreed about which alternatives should be considered (un)feasible and (in)sufficiently explored: conventional strategies (‘downstream solutions’ stance) or systematic changes to health care, political and agricultural systems (‘upstream solutions’ stance). Finally, respondents held different views on nature and whether the use of GDTs is compatible with humans’ role in nature (‘interference’ stance) or not (‘non-interference stance’).ConclusionsThis interview study helps to disentangle the debate on GDTs by providing a better understanding of the moral views of GDT experts. The obtained insights provide valuable stepping-stones for a constructive debate about underlying value conflicts and call attention to topics that deserve further (normative) reflection. Further evaluation of these issues can facilitate the debate on and responsible development of GDTs. (shrink)

In recent years, exposome research has been put forward as the next frontier for the study of human health and disease. Exposome research entails the analysis of the totality of environmental exposures and their corresponding biological responses within the human body. Increasingly, this is operationalized by big-data approaches to map the effects of internal as well as external exposures using smart sensors and multiomics technologies. However, the ethical implications of exposome research are still only rarely discussed in the literature. Therefore, (...) we conducted a systematic review of the academic literature regarding both the exposome and underlying research fields and approaches, to map the ethical aspects that are relevant to exposome research. We identify five ethical themes that are prominent in ethics discussions: the goals of exposome research, its standards, its tools, how it relates to study participants, and the consequences of its products. Furthermore, we provide a number of general principles for how future ethics research can best make use of our comprehensive overview of the ethical aspects of exposome research. Lastly, we highlight three aspects of exposome research that are most in need of ethical reflection: the actionability of its findings, the epidemiological or clinical norms applicable to exposome research, and the meaning and action–implications of bias.

Biomedical research funding bodies across Europe and North America increasingly encourage—and, in some cases, require—investigators to involve members of the public in funded research. Yet there remains a striking lack of clarity about what ‘good’ or ‘successful’ public involvement looks like. In an effort to provide guidance to investigators and research organisations, representatives of several key research funding bodies in the UK recently came together to develop the National Standards for Public Involvement in Research. The Standards have critical implications for (...) the future of biomedical research in the UK and in other countries as researchers and funders abroad look to the Standards as a model for their own policy development. We assess the Standards and find that despite offering useful suggestions for dealing with practical challenges associated with public involvement, the Standards fail to address fundamental questions about when, why and with whom public involvement should be undertaken in the first place. We show that presented without this justificatory context, many of the recommendations in the Standards are, at best, fragments that require substantial elaboration by those looking to apply the Standards in their own work and, at worst, subject to potentially harmful misapplication by well-meaning investigators. As funding bodies increasingly push for public involvement in research, the key lesson of our analysis is that future recommendations about how public involvement should be conducted cannot be coherently formulated without a clear sense of the underlying goals and rationales for public involvement.

Neurobiologist William Calvin explores the human brain, positing that the neurons in the brain operate in an accelerated version of biological evolution, evolving ideas through random variations and selections, and supports his hypothesis with numerous ca.

Background: Exposomics, the study of the exposome, is flourishing, but the field is not well defined. The term “exposome” refers to all environmental influences and associated biological responses throughout the lifespan. However, this definition is very similar to that of the term “environment”—the external elements and conditions that surround and affect the life and development of an organism. Consequently, the exposome seems to be nothing more than a synonym for the environment, and exposomics a synonym for environmental research. As a (...) result, some have rebranded their “standard” environmental health research with the neologistic exposome term, whereas others ignore or seek to abandon the seemingly redundant concept of the exposome. -/- Objectives: We argue that exposomics needs to sharpen its mission focus to counteract this apparent redundancy. Exposomics should be defined as a research program in environmental health aimed at enabling a comprehensive and discovery-driven approach to identifying environmental determinants of human health. Similar to the aim of the Human Genome Project, exposomics aims to analyze the complete complexity of exposures and their corresponding biological responses. Exposomics’ primary premise is that the existence of undiscovered, potentially interconnected, nongenetic (environmental) risk factors for health necessitates a comprehensive discovery-driven analysis approach. -/- Discussion: We argue that exposomics researchers should adopt our reconceptualization of exposomics and focus on the productiveness and integrity of their research program: its purpose and principles. We suggest that exposomics researchers should coordinate the writing of reviews that assess the program’s productiveness and integrity, as well as provide a platform for exposomics researchers to define their vision for the field.

Scientific discoveries are often to some degree influenced by luck. Whether luck’s influence is at odds with common-sense intuitions about responsibility, is the central concern of the philosophical debate about moral luck. Do scientists acknowledge that luck plays a role in their work and – if so – do they consider it morally problematic? The present article discusses the results of four focus groups with scientists, who were asked about their views on luck in their fields and its moral implications. (...) The participants underscored circumstantial luck as a key dimension of luck in science. Nevertheless, most participants insisted that there are ways of executing ‘control’ in science: They believe that virtues and skills can increase one’s chances for success. The cultivation of these skills and virtues was considered a reasonable ground for pride. Prizes and rewards were rarely tied to personal desert, but instead to their societal function. (shrink)

Autonomy of people on the autism-spectrum has only been very rarely conceptually explored. Autism spectrum is commonly considered a hetereogenous disorder, and typically described as a behaviorally-defined neurodevelopmental disorder associated with the presence of social-communication deficits and restricted and repetitive behaviors. Autism research mainly focuses on the behavior of autistic people and ways to teach them skills that are in line with social norms. Interventions such as therapies are being justified with the assumption that autists lack the capacity to be (...) self-reflective and to be “author of their lives”. We question this assumption, as some empirical research shows that autists are aware of their strengths and are critical about social norms, we take this as a starting point to reconsider the beliefs about autistic people’s capacities. As a theoretical framework, we draw on Berlin’s idea of positive and negative liberty as he clearly distinguishes between one’s own developed preferences and the simple absence of interference. By drawing on the concept of positive liberty, we illustrate that a lot of autists are aware of their own needs, and usually do not deny their own needs, values and interests. This makes them less prone than non-autistic people to adapt their preferences to external influences, which might be seen as sticking to an authentic way of living. Our analysis shows that many autists are hindered to be autonomous due to unjustified interference, unreflected assumptions about their self-determination, or by paternalistic actions. These observations contribute to a better understanding when help and interference are justified and a more differentiated understanding of autonomy of autistic people. (shrink)

This contribution sets out to criticize the prominent metaphor of “death while alive” in the context of dementia. We first explain the historical origin and development as well as the philosophical premises of the image. We then take a closer look at its implications for understanding dementia and societal attitudes and behaviours towards those affected. In doing so, we adopt a life course perspective that seeks to account for the ethical significance of the temporal extension and structure of human life. (...) According to this perspective, individual existence in time is characterized by normative standards of age-appropriate behavior, evaluative standards of a good life, and teleological notions of successful development which require theoretical analysis and ethical discussion. Such a perspective can contribute significantly to spelling out the implications of the metaphor of death while alive and to criticizing their problematic aspects. Indeed, it makes clear that this metaphor aligns dementia with a different point in the human life course, thus ultimately framing it as a kind of deviation from the biographical norm, a disruption in an assumed temporal order of existence. At the same time, the life course perspective can help to understand why this conception involves ethically problematic distortions and blind spots. The resulting considerations allow conclusions with regard to medical and care ethical debates about self-determination, surrogate decision making, and advance directives in the context of dementia. Furthermore, on a theoretical-conceptual level, they also illustrate the importance of a biography- and culture-sensitive approach to philosophical and ethical reasoning in biomedicine and the life sciences.

Unsere Sicht der Demenz ist von kulturellen Metaphern geprägt. Sie ziehen Analogien zu vertrauten Erfahrungsbereichen und eröffnen so ein Verständnis von einem ansonsten schwer fassbaren und letzten Endes unergründlichen Geschehen. In zeitgenössischen Diskursen über die Demenz spielen insbesondere zwei biographische Metaphern eine maßgebliche Rolle: die der,Rückkehr in die Kindheit‘ und die des,Todes bei lebendigem Leib‘. Der Beitrag unterzieht beide Vorstellungen einer kritischen Reflexion. Er erläutert zunächst die kulturgeschichtliche Herkunft und Bedeutung der Kindheits- und Todesmetapher. Im Anschluss geht er ihren Implikationen (...) für das Verständnis von Demenz und die Einstellungen und Verhaltensweisen gegenüber den Betroffenen nach. Dabei kommt eine Lebensverlaufsperspektive zum Tragen, die die Bedeutung der zeitlichen Erstreckung und Verlaufsstruktur des menschlichen Lebens für die ethische Theoriebildung systematisch zu berücksichtigen sucht. Auf diese Weise lässt sich verdeutlichen, dass beide Metaphern die Altersdemenz letztlich einem anderen Punkt des menschlichen Lebens angleichen und sie damit in je unterschiedlicher Weise als eine Art biographischer Normabweichung auffassen. Die Auseinandersetzung erlaubt Schlussfolgerungen mit Blick auf medizin- und pflegeethische Debatten um Selbstbestimmung, Stellvertreterentscheidungen und Vorausverfügungen im Kontext der Altersdemenz. Auf einer theoretisch-konzeptionellen Ebene verdeutlicht sie darüber hinaus auch die Bedeutung einer biographie- und kultursensiblen Perspektive für die ethische Theoriebildung im Allgemeinen.

I argue against pessimistic readings of the Buddhist tradition on which unawakened beings invariably have lives not worth living due to a preponderance of suffering (duḥkha) over well-being.

Gene drive technologies (GDTs) have been proposed as a potential new way to alleviate the burden of malaria, yet have also raised ethical questions. A central ethical question regarding GDTs relates to whether it is morally permissible to intentionally modify or eradicate mosquitoes in this way and how the inherent worth of humans and non-human organisms should be factored into determining this. Existing analyses of this matter have thus far generally relied on anthropocentric and zoocentric perspectives and rejected an individualist (...) biocentric outlook in which all living organisms are taken to matter morally for their own sake. In this paper, we reconsider the implications of taking a biocentric approach and highlight nuances that may not be evident at first glance. First, we shortly discuss biocentric perspectives in general, and then outline Paul Taylor’s biocentric theory of respect for nature. Second, we explore how conflicting claims towards different organisms should be prioritised from this perspective and subsequently apply this to the context of malaria control using GDTs. Our ethical analysis shows that this context invokes the principle of self-defence, which could override the pro tanto concerns that a biocentrist would have against modifying malaria mosquitoes in this way if certain conditions are met. At the same time, the case study of GDTs underlines the relevance of previously posed questions and criticism regarding the internal consistency of Taylor’s egalitarian biocentrism. (shrink)

In heart, the propagation of electrical activity is mediated by intercellular channels, referred to as junctional channels, aggregated into gap junctions and localised between myocytes. These channels consist of structurally related transmembrane proteins, the connexins, three of which (CX43, CX40 and CX45) have been shown to be associated with the myocytes of mammalian heart; a fourth, CX37, was detected exclusively in endothelial cells. In this paper, we review the recent data dealing with the topographical heterogeneity of expression of these connexins (...) in the different cardiac tissues and the unique conductance properties of the channels they form, and attempt to assess the role played by each connexin and the consequences of their multiplicity in the propagation of action potentials.

Endosomes shuttle select cargoes between cellular compartments and, in doing so, maintain intracellular homeostasis and enable interactions with the extracellular space. Directionality of endosomal transport critically impinges on cargo fate, as retrograde (microtubule minus‐end directed) traffic delivers vesicle contents to the lysosome for proteolysis, while the opposing anterograde (plus‐end directed) movement promotes recycling and secretion. Intriguingly, the endoplasmic reticulum (ER) is emerging as a key player in spatiotemporal control of late endosome and lysosome transport, through the establishment of physical contacts (...) with these organelles. Earlier studies have described how minus‐end‐directed motor proteins become discharged from vesicles engaged at such contact sites. Now, Raiborg et al. implicate ER‐mediated interactions, induced by protrudin, in loading plus‐end‐directed motor kinesin‐1 onto endosomes, thereby stimulating their transport toward the cell's periphery. In this review, we recast the prevailing concepts on bidirectional late endosome transport and discuss the emerging paradigm of inter‐compartmental regulation from the ER‐endosome interface viewpoint.

In _Ontological Terror_ Calvin L. Warren intervenes in Afro-pessimism, Heideggerian metaphysics, and black humanist philosophy by positing that the "Negro question" is intimately imbricated with questions of Being. Warren uses the figure of the antebellum free black as a philosophical paradigm for thinking through the tensions between blackness and Being. He illustrates how blacks embody a metaphysical nothing. This nothingness serves as a destabilizing presence and force as well as that which whiteness defines itself against. Thus, the function of (...) blackness as giving form to nothing presents a terrifying problem for whites: they need blacks to affirm their existence, even as they despise the nothingness they represent. By pointing out how all humanism is based on investing blackness with non-Being—a logic which reproduces antiblack violence and precludes any realization of equality, justice, and recognition for blacks—Warren urges the removal of the human from its metaphysical pedestal and the exploration of ways of existing that are not predicated on a grounding in Being.

Many accept the following three theses in animal ethics. First, although animal welfare should not be—or at least, need not be—our top moral priority, it is not a trivial one either. Second, if an animal is sentient, then it is a moral patient. Third, the extinction of an animal species is a tragic outcome that we have moral reason to prevent. I argue that a traditional (i.e., pre-modern) Buddhist perspective pushes against the first thesis and that a naturalized Buddhist perspective (...) is inconsistent with the latter two. (shrink)
