Concerns about the risks of unmitigated greenhouse gas emissions are growing. At the same time, confidence that international policy agreements will succeed in considerably lowering anthropogenic greenhouse gas emissions is declining. Perhaps as a result, various geoengineering solutions are gaining attention and credibility as a way to manage climate change. Serious consideration is currently being given to proposals to cool the planet through solar-radiation management. Here we analyze how the unique and nontrivial risks of geoengineering strategies pose fundamental questions at (...) the interface between science and ethics. To illustrate the importance of integrated ethical and scientific analysis, we define key open questions and outline a coupled scientific-ethical research agenda to analyze solar-radiation management geoengineering proposals. We identify nine key fields of coupled research including whether solar-radiation management can be tested, how quickly learning could occur, normative decisions embedded in how different climate trajectories are valued, and justice issues regarding distribution of the harms and benefits of geoengineering. To ensure that ethical analyses are coupled with scientific analyses of this form of geoengineering, we advocate that funding agencies recognize the essential nature of this coupled research by establishing an Ethical, Legal, and Social Implications program for solar-radiation management.

Le traité Du Régime se démarque des autres traités du corpus hippocratique à bien des égards. Aucun autre texte de ce corpus n’a poussé aussi loin le lien entre le corps humain en tant que microcosme et le cosmos, son macrocosme. Ce lien se manifeste notamment dans de multiples analogies, dans des expressions communes utilisées pour les décrire, ainsi que dans des explications identiques des phénomènes qui les caractérisent. Le présent article enquêtera sur une expression spécifique liant l’homme et le (...) cosmos : le terme περίοδος. Dans la continuité des travaux de Luc Brisson et Jacques Jouanna qui ont signalé plusieurs traits communs au Timée de Platon et au traité Du Régime, il s’agira de mettre en lumière l’importance du terme περίοδος, du concept de rotation/révolution, dans l’association microcosme-macrocosme, autant d’un point de vue structurel que fonctionnel.

The precarious rights of senior citizens, especially those who are highly educated and who are expected to counsel and guide the younger generations, has stimulated the creation internationally of advocacy associations and opinion leader groups. The strength of these groups, however, varies from country to country. In some countries, they are supported and are the focus of intense interest; in others, they are practically ignored. For this is reason we believe that the creation of a network of all these associations (...) is essential. The proposed network would act as a support for the already-existing policies of the United Nations’ High Commission for Human Rights, of independent experts, and of the Global Alliance for the Rights of Older People. All three have long ago recommended the creation of a recognized instrument for uniting presently scattered efforts. The proposed network, therefore, will seek to promote the international exchange of relevant expertise, and it will reinforce the commitments and actions that single countries are currently taking to meet these objectives. For example, informative public events can be organised to promote particular support initiatives and to provide an opportunity for new members of the network to be presented. The network will promote health for senior citizens, disease prevention, senior mobility, safe free time for seniors, alimentary education, protection against new risks and dangers, as well as equity in the services necessary for seniors to adopt new information and communication technologies. In the case of retired academic members, the network will promote equality with respect to continuing use of digital technologies (particularly email), continuing access to research libraries, and the guaranteed ability for seniors to fund their own research programs and to deliver free seminars.

At a distance of more ten years from publication (2000 French/2005 English translation), with this essay I will re-read, comment and discuss, in different way and in form of anthological sketch, the Derridean volume ‘On Touching-Jean Luc Nancy’, focusing in particular on its ‘tangents and its metonymies’, its manifold entanglements with the metaphysics of touch and bodily connections. Making use of the geometrical figure of the tangent, Derrida affirms that "[if] philosophy has touched the limit [my emphasis-J. D. ]. (...) of the ontology of subjectivity, this is because philosophy has been led to this limit”. To touch is to touch a limit, a limit without depth or surface. How have we regarded touching in the past? The body? My thesis is that if Derridean reflection remains mostly anchored to Jean-Luc Nancy’s Corpus, it is inspired nevertheless by a different deconstructive gesture/s similar to different geometric tangents (the deconstructive practice is similar to the tracing of many tangents). Discussing in particular Nancy’s Dis-Enclosure: The Deconstruction of Christianity, Derrida’essay ‘Deconstruction of Christianity’ and devoting an entire section of the book to the sense of touch in the Gospels, Derrida gives us numerous and special considerations on deconstruction and the deconstruction of touch in Christianity, admitting as well the enormity of this task. A reflection on the Kas Saghafi, “Safe, Intact”: Derrida, Nancy, and the “Deconstruction of Christianity” will follow in an exemplary way. Following a discussion of touch and the body in both animal and human spheres, in the closing section of the essay, I will comment on the Patrick Llored’s essay A Philosophy of Touching Between the Human and the Animal: The Animal Ethics of Jacques Derrida, recently published in A Companion to Derrida (2014). This study addresses highly topical questions such as: ‘What does it teach us about touch, but also about the body and the life of the animal? To what extent is it capable of renewing our knowledge [connaissance] of non-human life and of generating an animal ethics reconceived from top to bottom? If touching is coextensive with the living body, that implies not only that we place the haptical question at the centre of reflection on the animal, but also that we take into account the consequence that is most disruptive for us today (A Companion, p. 512). And conclude along with Patrick Llored that the question of touch promises to transform everything we have understood until now about animality. (shrink)

In the Third Antinomy of the Critique of Pure Reason (1781) [Kritik der reinen Vernunft], Immanuel Kant (1724-1804) associates freedom with infinity. According to the definition given in this book, only an infinite being not subject to causality can be defined as free. However, the fact that a finite being, such as a human, is always subject to the laws of nature implies that they are perpetually bound by causality, which hinders their freedom. Freedom devoid of causality cannot be theoretically (...) justified. Another reason for this is Kant’s assertion in the Second Analogy of Critique of Pure Reason, where he states that everything in the phenomenal world is subject to causality. Accordingly, freedom can be conceived not in the phenomenal world but only in the noumenal world. In the First Critique, freedom, defined as a cause without a cause, a cause without being the result of another cause, later be characterized as negative freedom in the third section of the Groundwork of the Metaphysics of Morals (1785) [Grundlegung zur Metaphysik der Sitten]. Such conceptualization of freedom cannot be determined by any other cause than itself. While there may be a theoretical foundation for accepting such a cause as uncaused, we have moral reasons to believe in it. This moral foundation in question guides us toward the notion of positive freedom. Here, unlike negative freedom, we are subject to moral laws, and as long as we comply with these, we can experience freedom as a finite being. This is because adhering to the laws we set for ourselves enables us to be morally the cause of our own actions. Thus, Kant renders freedom through positive freedom. Following this line of argument, negative freedom appears meaningful to us only within the framework of positive freedom. Jean-Luc Nancy (1940-2021) finds a problematic Kantian account of freedom as an uncaused cause in his book The Experience of Freedom (1988) [L’expérience de la liberté]. Because, according to this perspective, humans are not only subject to the laws of nature but also to moral cause-and-effect relationships with others, they exist at the ix limit of freedom. By this means, considering freedom as a duty imposed on the subject leads to ambiguous analyses such as negative/positive freedom in Kantian philosophyーIn post-Kantian philosophy, the ambiguity persists until Friedrich Wilhelm Joseph Schelling (1775-1854)1 , who finds the solution by negating freedom. Therefore, according to Nancy, freedom should be considered not as a Kantian Idea but through its relationship with human finitude and experience. Thus, through the criticism directed at Kant in Martin Heidegger’s (1889-1976) Kant and the Problem of Metaphysics (1929) [Kant und das Problem der Metaphysik], Nancy attempts to resolve the confusion created by the concept of freedom, which despite being associated with infinity in Kant, is made possible in the practical world through respect for the moral law. In this direction, Nancy finds the solution in the freedom that becomes conceptually elusive, transforming it into an act that goes beyond being a mere duty and which permeates all our experiences. In this book, Nancy introduces the initial stages of “community” and “singularity” concepts, which he would later develop further. For this, he begins the book's introductory section by emphasizing Martin Heidegger’s statement in §9 of Being and Time (1927) [Sein und Zeit], where “freedom” is mentioned as another name for existence. As a justification, he refers to the concept of Da-sein [being-there] and states that every being [être] is a being-in-common [être-en-commun], and freedom should be thought of through this. Namely, the problem of freedom is approached not as a political or ethical issue but as an ontological matter. Within the framework of beingin-common, this situation transforms into an ontological “generosity [générosité ontologique].” -/- 1 Philosophical Investigations into the Essence of Human Freedom [Philosophische Untersuchungen über das Wesen der menschlichen Freiheit und die damit zusammenhängenden Gegenstände], Schelling, approaches freedom not through infinity but rather through finitude. While Heidegger and Nancy pursue different paths, they both adhere to the idea of finitude freedom in Schelling. x Despite primarily emphasizing Heidegger’s thought in writing this text as his aggrégation thesis, Jean-Luc Nancy desires to transcend it and maintain a certain distance. This transcendence and distancing include authors from the French Phenomenological tradition, such as Georges Bataille (1897-1962), Maurice Blanchot (1907-2003), and Jean-François Lyotard (1924-1998), and also incorporate the emphasis from Hannah Arendt (1906-1975) that death cannot be thought of independently of life. Referencing many philosophers from the continental philosophy tradition and developing a thematic reading through freedom, this bookーlike Nancy’s other worksーseeks ways to experience philosophy and thought freely in this own writing experience. So much so that this book, unlike Nancy’s other works like The Inoperative Community (1986) [La communauté désoeuvrée] ve Being Singular Plural (1996) [Être Singulier Pluriel], which is not widely discussed in secondary sources, is challenging to follow. Therefore, in examining this book as my Master’s research thesis and addressing the idea of freedom in Nancy, I found it appropriate to adopt a close reading method. Certainly, this research should not be considered independent of works such as The Discourse of Syncope (1976) [Le discours de la syncope], The Categorical Imperative (1983) [L’impératif catégorique], as they serve as examples of while engaging in philosophy, how Nancy refers and relates to the works within the philosophical tradition.

Reseña en español del diálogo entre A. Badiou y J.-L. Nancy, editado por Jan Völker y publicado en 2017.

In this article, I argue that G. A. Cohen’s defense of the feminist slogan, “The personal is political”, his argument against Rawls’s restriction of principles of justice to the basic structure of society, depends for its intelligibility on the ability to distinguish—with reasonable but perhaps not perfect precision—between those situations in which what Nancy Rosenblum has called “the logic of congruence” is validly invoked and those in which it is not. More importantly, I suggest that the philosophical shape (...) of Cohen’s critique makes it difficult for him to supply the required criterion, and that the methodological “intuitionism” he claims to be committed to is at odds with his larger argument against Rawls concerning the subject of justice.

Societies of the East are often contrasted with those of the West in their stances toward technology. This paper explores these perceived differences in the context of international ethics guidance for artificial intelligence (AI) and robotics. Japan serves as an example of the East, while Europe and North America serve as examples of the West. The paper’s principal aim is to demonstrate that Western values predominate in international ethics guidance and that Japanese values serve as a much-needed corrective. We recommend (...) a hybrid approach that is more inclusive and truly ‘international’. Following an introduction, the paper examines distinct stances toward robots that emerged in the West and Japan, respectively, during the aftermath of the Second World War, reflecting history and popular culture, socio-economic conditions, and religious worldviews. It shows how international ethics guidelines reflect these disparate stances, drawing on a 2019 scoping review that examined 84 international AI ethics documents. These documents are heavily skewed toward precautionary values associated with the West and cite the optimistic values associated with Japan less frequently. Drawing insights from Japan’s so-called ‘moonshot goals’, the paper fleshes out Japanese values in greater detail and shows how to incorporate them more effectively in international ethics guidelines for AI and robotics.

This paper replies to a commentary by John-Stewart Gordon on our paper, “The Moral Standing of Social Robots: Untapped Insights from Africa.” In the original paper, we set forth an African relational view of personhood and show its implica- tions for the moral standing of social robots. This reply clarifies our position and answers three objections. The objections concern (1) the ethical significance of intelligence, (2) the meaning of ‘pro-social,’ and (3) the justification for prioritizing humans over pro-social robots.

The conventional wisdom about advance care planning holds that the normative force of my prior wishes is simply that they are mine. It is their connection to me that matters. This paper challenges conventional thinking. I propose that the normative force of prior wishes does not depend exclusively on personal identity. Instead, it sometimes depends on a special relationship that exists between a prior, capacitated person and a now incapacitated person. I consider what normative guidance governs persons who stand in (...) a special relationship, and contrast these with the standard model of respect for autonomy. My conclusion is that advance care planning for individuals who have lost decision-making capacity should incorporate the virtues of prudence and integrity, even when one and the same person ceases to exist, and respect for personal autonomy is no longer relevant.

A cognitive ethnography of how bioengineering scientists create innovative modeling methods. In this first full-scale, long-term cognitive ethnography by a philosopher of science, Nancy J. Nersessian offers an account of how scientists at the interdisciplinary frontiers of bioengineering create novel problem-solving methods. Bioengineering scientists model complex dynamical biological systems using concepts, methods, materials, and other resources drawn primarily from engineering. They aim to understand these systems sufficiently to control or intervene in them. What Nersessian examines here is how cutting-edge (...) bioengineering scientists integrate the cognitive, social, material, and cultural dimensions of practice. Her findings and conclusions have broad implications for researchers in philosophy, science studies, cognitive science, and interdisciplinary studies, as well as scientists, educators, policy makers, and funding agencies. In studying the epistemic practices of scientists, Nersessian pushes the boundaries of the philosophy of science and cognitive science into areas not ventured before. She recounts a decades-long, wide-ranging, and richly detailed investigation of the innovative interdisciplinary modeling practices of bioengineering researchers in four university laboratories. She argues and demonstrates that the methods of cognitive ethnography and qualitative data analysis, placed in the framework of distributed cognition, provide the tools for a philosophical analysis of how scientific discoveries arise from complex systems in which the cognitive, social, material, and cultural dimensions of problem-solving are integrated into the epistemic practices of scientists. Specifically, she looks at how interdisciplinary environments shape problem-solving. Although Nersessian’s case material is drawn from the bioengineering sciences, her analytic framework and methodological approach are directly applicable to scientific research in a broader, more general sense, as well.

Slurring is a kind of hate speech that has various effects. Notable among these is variable offence. Slurs vary in offence across words, uses, and the reactions of audience members. Patterns of offence aren’t adequately explained by current theories. We propose an explanation based on the unjust power imbalance that a slur seeks to achieve. Our starting observation is that in discourse participants take on discourse roles. These are typically inherited from social roles, but only exist during a discourse. A (...) slurring act is a speech-act that alters the discourse roles of the target and speaker. By assigning discourse roles the speaker unjustly changes the power balance in the dialogue. This has a variety of effects on the target and audience. We show how these notions explain all three types of offence variation. We also briefly sketch how a role and power theory can help explain silencing and appropriation. Explanatory power lies in the fact that offence is correlated with the perceived unjustness of the power imbalance created. (shrink)

In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made (...) at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that “self-loss,” far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with “selflessness” as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

We call for a new philosophical conception of models in physics. Some standard conceptions take models to be useful approximations to theorems, that are the chief means to test theories. Hence the heuristics of model building is dictated by the requirements and practice of theory-testing. In this paper we argue that a theory-driven view of models can not account for common procedures used by scientists to model phenomena. We illustrate this thesis with a case study: the construction of one of (...) the first comprehensive model of superconductivity by London brothers in 1934. Instead of theory-driven view of models, we suggest a phenomenologically-driven one. (shrink)

Scientific research is a highly complex and creative domain of human activity. In addition to its intrinsic value, understanding scientific thinking provides insight into the creative potential of human psychological capacities, as they are imbedded in rich social, material, and cultural environments. I discuss findings from my own investigations using two forms of qualitative research suited to studying scientific thinking as situated in context: cognitive-historical and cognitive-ethnographic.

A topic of special importance when it comes to responsibility and implicit bias is responsibility for knowledge. Are there strategies for becoming more responsible and respectful knowers? How might we work together, not just as individuals but members of collectives, to reduce the negative effects of bias on what we see and believe, as well as the wrongs associated with epistemic injustice? To explore these questions, Chapter 9 introduces the concept of epistemic responsibility, a set of practices developed through the (...) cultivation of basic epistemic virtues, such as open-mindedness, epistemic humility, and diligence that help knowers seek information about themselves, others, and the world.

We are living at the dawn of the first truly scientific picture of the universe-as-a-whole, yet people are still dragging along prescientific ideas about God that cannot be true and are even meaningless in the universe we now know we live in. This makes it impossible to have a coherent big picture of the modern world that includes God. But we don't have to accept an impossible God or else no God. We can have a real God if we redefine (...) God in light of knowledge no one ever had before. The key question is, “Could anything actually exist in the scientific universe that is worthy of the name, God?” My answer is yes: God is an “emergent phenomenon,” as real as the global economy or the government or the worldwide web, which are all emergent phenomena. But God arose from something deeper: the complex interactions of all humanity's aspirations. An emerging God has enormous implications. (shrink)

It is often assumed that the chief responsibility medical professionals bear is patient care and advocacy. The meeting of other duties, such as ensuring a more just distribution of medical resources and promoting the public good, is not considered a legitimate basis for curtailing or slackening beneficial patient services. It is argued that this assumption is often made without sufficient attention to foundational principles of professional ethics; that once core principles are laid bare this assumption is revealed as largely unwarranted; (...) and, finally, that these observations at the level of moral theory should be reflected, in various ways, in medical practice. Specifically, this essay clarifies a tension that exists between different kinds of moral principles and explores the possibility of dissipating that tension by shoring up foundational principles. The paper begins by setting out three alternative models of how best to balance patient advocacy responsibilities with broader social responsibilities. It then turns to critically assess these models and argue that one has several advantages over the others. (shrink)

This chapter focuses on a novel class of models used in frontier research in the bioengineering sciences – in vitro simulation models – that provide the basis for biological experimentation. These bioengineered models are hybrid constructions, composed of living tissues or cells and engineered materials. Specifically, it discusses the processes through which in vitro models were built, experimented with, and justified in a tissue engineering lab. It examines processes of design, construction, experimentation, evaluation, and redesign of in vitro simulation models, (...) in general, as instances of building the source analogy (as distinguished from retrieving an analogy), which figures prominently in creative frontier scientific research. Building the analogical source is a bootstrapping process, which furthers the articulation, as well as the solution of the problem. -/- . (shrink)

In "The Virtues of Sharing" I defend two central theses: that sharing is our most overarching ethical ideal, and that virtue ethics is able to serve as a comprehensive and free-standing approach to moral theory. My arguments for these theses are intertwined, because they are also designed to show how a virtue-ethical theory that treats the "Will to Share" as the basis of moral agency helps to resolve the contemporary Justice/Care Debate.

The “problem of intentionality” from the vantage point of a representational understanding of mind is explaining what thoughts and beliefs are and how they guide behaviour. From an anti-representationalist perspective, on the other hand, on which cognition itself is taken to be a kind of action, intentionality is a capacity to engage in behaviour that is meaningfully directed toward or about some situation. That these are not in fact competing insights is obscured by the representational/anti-representational framing of the debate. This (...) paper begins the work of shifting the conversation in two ways: (1) by arguing that it is the commitment to internal representations, not the acknowledgement of a role for representation per se, that is problematic; and, (2) by describing an alternative, externalist, representational approach that draws on extended, embodied, enactive insights.

In this lyrical meditation on listening, Jean-Luc Nancy examines sound in relation to the human body. How is listening different from hearing? What does listening entail? How does what is heard differ from what is seen? Can philosophy even address listening, écouter, as opposed to entendre, which means both hearing and understanding? Unlike the visual arts, sound produces effects that persist long after it has stopped. The body, Nancy says, is itself like an echo chamber, responding to music (...) by inner vibrations as well as outer attentiveness. Since “the ear has no eyelid” (Quignard), sound cannot be blocked out or ignored: our whole being is involved in listening, just as it is involved in interpreting what it hears. The mystery of music and of its effects on the listener is subtly examined. Nancy’s skill as a philosopher is to bring the reader companionably along with him as he examines these fresh and vital questions; by the end of the book the reader feels as if listening very carefully to a person talking quietly, close to the ear.

Atualmente, biotecnologias são empregadas na forma de protocolos a fim de sincronizar o crescimento folicular e a ovulação, bem como permitir que vacas atuem como receptoras de embriões visando melhorar o potencial genético do rebanho. O objetivo desse estudo foi avaliar o efeito da utilização de implantes intravaginais de progesterona de 1º, 2º e 3º uso no protocolo de transferência de embriões em tempo fixo (TETF) sobre a taxa de prenhez em receptoras girolandas. O experimento ocorreu em uma fazenda localizada (...) no município de São Sebastião do Maranhão (MG). Foram utilizadas 74 vacas submetidas aos seguintes protocolos: No dia 0 (D0) administrou-se 2 ml de 17β-Estradiol e progesterona e foi colocado o implante intravaginal de progesterona. Estes implantes foram colocados de forma aleatória, sendo de 1° uso (grupo 1; n=15), 2° (grupo 2; n=24) ou 3° (grupo 3; n=35).No D8, os implantes foram retirados e administrou-se 2 ml PGF2α; 1,5 ml de eCG e 1 ml de 17β-Estradiol e progesterona. A inovulação dos embriões in vitroo correu no D (16) para todas as vacas que apresentaram um corpo lúteo. As variáveis qualitativas (prenhe ou não prenhe) foram comparadas em tabelas de contingência e analisadas pelo teste de qui-quadrado a 5% de probabilidade. Neste estudo não houve diferença estatística entre os grupos protocolados em relação ao aproveitamento como receptoras: 1º uso (53,3%), 2º (79,2%) e 3º (68,65). Ademais, observou-se uma taxa de prenhez entre os grupos de 37,5% para o 1º uso, 42,1% para o 2º e 33,3% para o 3º (P>0,05). Dentre as vantagens ao reaproveitamento dos implantes multiusos destaca-se a redução dos custos dos protocolos hormonais, já que a progesterona é o hormônio mais oneroso, desta forma, a maximização do uso reduz o valor final do protocolo sem prejuízos a taxa de prenhez.

A society is said to age when its number of older members increases in relation to its number of younger members. The societies in most of the world’s industrialized nations have been aging since at least 1800. In 1800 the demographic makeup of developed countries was similar to that of many Third World countries in the early 1990s with roughly half the population under the age of 16 and very few people living beyond age of 60. Since that time, increases (...) in life expectancy, combined with declines in fertility rates, have dramatically increased the proportion of older persons in developed nations. The rapid increase in the number of older persons relative to younger ones carries important societal implications. In the domain of healthcare, societal aging will increase costs and exert greater pressure to ration services. It will, thus, bring to the fore questions, regarding a just distribution of healthcare between young and old age groups. This paper considers some of the most influential arguments to date for age-based rationing of health care. I show that these arguments fall short, and that the theoretical assumptions underlying them do not withstand careful scrutiny. (shrink)

This paper investigates the scope and limits of parents' and physicians' obligations to anencephalic newborns. Special attention is paid to the permissibility of harvesting anencephalic organs for transplant.

This analysis reveals that the presence of a close relationship between patients and beneficiaries is often crucial to justifying treating in these cases. In particular, the proper interpretation of the Kantian injunction against treating persons (...) as means only takes on a different light in the context of special relationships. The implications of this analysis for our responsibilities to anencephalic infants is clarified. (shrink)

There is a major debate as to whether there are non-causal mathematical explanations of physical facts that show how the facts under question arise from a degree of mathematical necessity considered stronger than that of contingent causal laws. We focus on Marc Lange’s account of distinctively mathematical explanations to argue that purported mathematical explanations are essentially causal explanations in disguise and are no different from ordinary applications of mathematics. This is because these explanations work not by appealing to what the (...) world must be like as a matter of mathematical necessity but by appealing to various contingent causal facts. (shrink)

The paper develops a positive account of the representational capacity of cognitive systems: simple, associationist learning mechanisms and an architecture that supports bootstrapping are sufficient conditions for symbol tool use. In terms of the debates within the philosophy of mind, this paper offers a plausibility account of representation externalism, an alternative to the reductive, computational/representational models of intentionality that still play a leading role in the field. Although the central theme here is representation, methodologically this view complements embodied, enactivist approaches (...) to studying cognition. (shrink)

Computational systems biologists create and manipulate computational models of biological systems, but they do not always have straightforward epistemic access to the content and behavioural profile of such models because of their length, coding idiosyncrasies, and formal complexity. This creates difficulties both for modellers in their research groups and for their bioscience collaborators who rely on these models. In this paper we introduce a new kind of visualization that was developed to address just this sort of epistemic opacity. The visualization (...) is unusual in that it depicts the dynamics and structure of a computer model instead of that model’s target system, and because it is generated algorithmically. Using considerations from epistemology and aesthetics, we explore how this new kind of visualization increases scientific understanding of the content and function of computer models in systems biology to reduce epistemic opacity.

In recent years, educational institutions have started using the tools of commercial data analytics in higher education. By gathering information about students as they navigate campus information systems, learning analytics “uses analytic techniques to help target instructional, curricular, and support resources” to examine student learning behaviors and change students’ learning environments. As a result, the information educators and educational institutions have at their disposal is no longer demarcated by course content and assessments, and old boundaries between information used for assessment (...) and information about how students live and work are blurring. Our goal in this paper is to provide a systematic discussion of the ways in which privacy and learning analytics conflict and to provide a framework for understanding those conflicts. -/- We argue that there are five crucial issues about student privacy that we must address in order to ensure that whatever the laudable goals and gains of learning analytics, they are commensurate with respecting students’ privacy and associated rights, including (but not limited to) autonomy interests. First, we argue that we must distinguish among different entities with respect to whom students have, or lack, privacy. Second, we argue that we need clear criteria for what information may justifiably be collected in the name of learning analytics. Third, we need to address whether purported consequences of learning analytics (e.g., better learning outcomes) are justified and what the distributions of those consequences are. Fourth, we argue that regardless of how robust the benefits of learning analytics turn out to be, students have important autonomy interests in how information about them is collected. Finally, we argue that it is an open question whether the goods that justify higher education are advanced by learning analytics, or whether collection of information actually runs counter to those goods.

Human behavior is frequently described both in abstract, general terms and in concrete, specific terms. We asked whether these two ways of framing equivalent behaviors shift the inferences people make about the biological and psychological bases of those behaviors. In five experiments, we manipulated whether behaviors are presented concretely (i.e. with reference to a specific person, instantiated in the particular context of that person’s life) or abstractly (i.e. with reference to a category of people or behaviors across generalized contexts). People (...) judged concretely framed behaviors to be less biologically based and, on some dimensions, more psychologically based than the same behaviors framed in the abstract. These findings held true for both mental disorders (Experiments 1 and 2) and everyday behaviors (Experiments 4 and 5) and yielded downstream consequences for the perceived efficacy of disorder treatments (Experiment 3). Implications for science educators, students of science, and members of the lay public are discussed. (shrink)

Moral distress is a well-documented phenomenon in the nursing profession, and increasingly thought to be implicated in a nation-wide nursing shortage in the US. First identified by the philosopher Andrew Jameton in 1984, moral distress has also proven resistant to various attempts to prevent its occurrence or at least mitigate its effects. While this would seem to be bad news for nurses and their patients, it is potentially good news for philosophical counselors, for whom there is both socially important and (...) philosophically interesting work to be done. In an effort to encourage such work, this paper explicates the philosophical (as opposed to more purely psychological or institutional) contours of the problem. A subsequent paper, titled 'A Philosophical Counseling Approach to Moral Distress,' will highlight ways in which such a response would differ from the strategies so far deployed within the nursing profession.

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.

We offer a critical survey of the most discussed accounts of epistemic peer disagreement that are found in the recent literature. We also sketch an alternative approach in line with a pluralist understanding of epistemic rationality.

This chapter discusses three types of sociable robots for older adults: robotic caregivers ; robotic friends ; and sex robots. The central argument holds that society ought to make reasonable efforts to provide these types of robots and that under certain conditions, omitting such support not only harms older adults but poses threats to their dignity. The argument proceeds stepwise. First, the chapter establishes that assisting care-dependent older adults to perform activities of daily living is integral to respecting dignity. Here, (...) the argument establishes the vital role that carebots-of-the-future might play in aged societies as the supply of working age adults falls shy of demand. Next, the chapter extends this analysis to designing friendbots for socially isolated older adults. The argument holds that reasonable efforts to provide access to friendbots for socially isolated adults is also a future societal responsibility. Finally, the chapter applies similar reasoning to show that societies ought to make reasonable efforts to support sexual capabilities for older adults who want to be sexual but are bereft of sex partners. The argument draws on capability accounts of justice to show that when central human capacities, such as bodily integrity; intimate relationships; and the use of senses, imagination and thought, are at risk of falling below a threshold level, society should intercede.

Hubert Dreyfus has argued recently that the frame problem, discussion of which has fallen out of favour in the AI community, is still a deal breaker for the majority of AI projects, despite the fact that the logical version of it has been solved. (Shanahan 1997, Thielscher 1998). Dreyfus thinks that the frame problem will disappear only once we abandon the Cartesian foundations from which it stems and adopt, instead, a thoroughly Heideggerian model of cognition, in particular one that does (...) not appeal to representations. I argue that Dreyfus is too hasty in his condemnation of all representational views; the argument he provides licenses only a rejection of disembodied models of cognition. In casting his net too broadly, Dreyfus circumscribes the cognitive playing field so closely that one is left wondering how his Heideggerian alternative could ever provide a foundation explanatorily robust enough for a theory of cognition. As a consequence, he dilutes the force of his legitimate conclusion, that disembodied cognitive models will not work, and this conclusion needs to be heard. By disentangling the ideas of embodiment and representation, at least with respect to Dreyfus‘ frame problem argument, the real locus of the general polemic between traditional computational/representational cognitive science and the more recent embodied approaches is revealed. From this, I hope that productive debate will ensue. (shrink)
