Goffi and Roux are interested in what makes some thought experiments work, while others do not work. They do not attempt to draw an a priori line between two types of thought experiments, but rather ask the following question: inasmuch as thought experiments are arguments, and notwithstanding the fact that some of them might involve the contemplation of an imaginary scenario, how is it that some of them work, while others do not? Taking inspiration from a counterfactual thought experiment (...) presented by Nicholas Rescher, they treat thought experiments as argumentative procedures resembling tests of consistency, which invite the experimenter to seek the weakest link in her body of beliefs. Equipped with this method, they examine two well-known successful thought experiments (Galileo’s two bodies strapped together, and Thomson’s violinist) and discuss Mach’s notion of thought experiments. Thus they reach the hypothesis that successful thought experiments respect the three following conditions: they do not deal with things, but with beliefs; they mobilise a set of beliefs shared by the interlocutors; and this set of beliefs has a hierarchical structure. Using once again examples written at different periods and taken from various disciplines (Descartes’ receding bodies, Aristotle’s weaving shuttles), Goffi and Roux argue that each of those conditions is individually necessary for a thought experiment to work. They finally conclude on the limits and consequences of their approach. (shrink)

Contre une interprétation déconstructiviste de la question de l'animalité, on s'attache à montrer, par une présentation précise des objections adressées à P. Singer par G. Francione, que l'éthique animale « classique » comporte en elle-même les ressources d'une pensée critique extrêmement audacieuse.

On se propose de fédérer les questions relevant de la bioéthique, des générations futures et de l’éthique environnementale autour du thème de la communauté morale. On examinera certains problèmes théoriques posés par l’élargissement de celle-ci. On soutiendra qu’il n’est possible d’y faire face qu’en se ralliant à une forme d’anthropocentrisme. Toutefois, il s’agit d’un anthropocentrisme méta-axiologique, pas d’un anthropocentrisme normatif: il ne saurait être question de soutenir que les intérêts des être humains ont, toujours et partout, priorité sur les intérêts (...) des autres créatures.

Après avoir rappelé, à la lumière des analyses de W. N. Hohfeld, ce que peut signifier le concept de droits, on montre que la notion d'obligations envers les générations futures est plus intelligible dans une théorie qui fonde les droits sur la possession d'intérêts que dans une théorie qui les reconduit à l'expression d'une volonté. Cette approche de la question génère toutefois le paradoxe suivant : la génération présente a l'obligation de prendre en compte les intérêts de générations futures sans (...) avoir pour autant l'obligation de faire en sorte qu'il existe des générations futures. On en conclut que les obligations envers les générations futures ne peuvent être que conditionnelles. (shrink)

Il s'agit de déterminer le statut des normes chez les nouveaux casuistes . On indique d'abord quelles sont les circonstances de cette nouvelle casuistique ; on suggère ensuite qu'elle exporte dans le domaine de l'éthique certaines thèses de T. Kuhn, comme le « modèle déductiviste », qu'elle prétend détrôner, s'alimentait au schéma Hempel-Oppenheim de l'explication scientifique. On suggère enfin que les nouveaux casuistes procèdent, de façon plus ou moins radicale, à une naturalisation des normes.It is intented to investigate about the (...) status of norms in the thought of the new casuists . First, the circumstances of the new casuistry are set out; then it is suggested that the new casuists have integrated in their argument concepts from T. Kuhn, just as the “deductivist model” they so sharply criticize integrates concepts from C.G. Hempel and P. Oppenheim. With regard to the initial question, it is shown that the new casuists uphold a kind of norms-naturalizing constructivism. (shrink)

French ethics of technology has followed a most peculiar path. Generally speaking, French philosophers of technology have dismissed the methodology of Applied Ethics as widely practiced. As a result, the most notorious thinkers have been those who have expressed the most considerable reservations about the “technical phenomenon.” I here attempt to establish that the most promising attempts to overcome this situation do not rise from social philosophy, but from a long-standing French tradition in the field of philosophy of life, supported (...) by an overriding project of integration of technology into culture.

As it is commonly used, the concept of dignity applies to people as well as to groups of people. It is sometimes supposed to encapsulate such widely different notions as privacy, physical or mental integrity and personality. There is something puzzling in such a situation. This article argues, firstly, that the concept of dignity is best understood when applying ‹only› to autonomy, perfectibility and rationality. Belonging to the language of morals, the concept of dignity has something strongly prescriptive built into (...) it: its function is to justify prohibitions in our ways of dealing with persons. But if interpreted as depending on the actual possession of some capacities, it fails to do its job, because it applies to too few people; and if interpreted as expressing an essence, it fails because it gives way to some form of discrimination. It is suggested that a two-level use of the notion of dignity could improve things, albeit at the cost of trivialising the notion. (shrink)

Les animaux peuvent-ils avoir des droits? La souffrance animale a-t-elle une importance morale? Les animaux sont-ils dotes de conscience? Telles sont les questions abordees dans cet ouvrage, qui se propose d'approfondir quelques pistes de reflexion a travers la lecture commentee de deux textes, l'un de John Stuart Mill (extrait de L'utilitarisme), l'autre de Donald Davidson (sur la cognition animale).

The controversy surrounding the use of hydroxychloroquine, an antimalarial drug, for COVID-19 has raised numerous ethical and policy problems. Since the suggestion that HCQ has potential for COVID-19, there have been varying responses from clinicians and healthcare institutions, ranging from adoption of protocols using HCQ for routine care to the conduct of randomised controlled trials to an effective system-wide prohibition on its use for COVID-19. In this article, we argue that the concept of ‘disease public profile’ has become a prominent, (...) if not the sole, determinant in decision-making across various healthcare responses to the pandemic. In the case of COVID-19, the disease’s public profile is based on clinical and non-clinical factors that include contagiousness, clinical presentation and media coverage. In particular, we briefly examine the dangers of a heightened public profile in magnifying the inequality of diseases and undermining three key ethical concepts, namely evidence-based practice, sustainable allocation and meaningful consent.

Most agents can acquire information about their environments as they operate. A good plan for such an agent is one that not only achieves the goal, but is also executable, i.e., ensures that the agent has enough information at every step to know what to do next. In this paper, we present a formal account of what it means for an agent to know how to execute a plan and to be able to achieve a goal. Such a theory is (...) a prerequisite for producing specifications of planners for agents that can acquire information at run time. It is also essential to account for cooperation among agents. Our account is more general than previous proposals, correctly handles programs containing loops, and incorporates a solution to the frame problem. It can also be used to prove programs containing sensing actions correct. (shrink)

Ce livre présente cinq entretiens avec des philosophes pionniers dans le champ de la bioéthique francophone, Anne Fagot-Largeault et Jean-Yves Goff i (France), Gilbert Hottois et Jean-Noël Missa (Belgique) et Marie-Hélène Parizeau (Québec), cinq personnalités de renom, connues pour leur trajectoire exceptionnelle. Les entretiens menés avec ces auteurs au sujet de leurs oeuvres, de leurs expériences dans des comités de bioéthique et des différents débats soulevés ces dernières années nous permettent de connaître leur travail, mais aussi de faire une (...) incursion dans le développement fulgurant de la bio-médecine et des biotechnologies des cinquante dernières années. Les conséquences de ces applications, les problèmes éthiques générés, les jugements favorables et défavorables à l'égard des changements sociaux qui se sont produits et le bouleversement d'idées qui s'en est suivi, sont autant d'aspects abordés dans ces entretiens. L'utilisation du langage courant exige un effort de synthèse important; aussi ces entretiens sous la forme d'une conversation, offrent-ils au lecteur une large vision panoramique, rigoureuse et concise de l'évolution de la bioéthique francophone.

We develop and apply a multi-dimensional account of explanatory depth towards a comparative analysis of inflationary and bouncing paradigms in primordial cosmology. Our analysis builds on earlier work due to Azhar and Loeb (2021) that establishes initial conditions fine-tuning as a dimension of explanatory depth relevant to debates in contemporary cosmology. We propose dynamical fine-tuning and autonomy as two further dimensions of depth in the context of problems with instability and trans-Planckian modes that afflict bouncing and inflationary approaches respectively. In (...) the context of the latter issue, we argue that the recently formulated trans-Planckian censorship conjecture leads to a trade-off for inflationary models between dynamical fine-tuning and autonomy. We conclude with the suggestion that explanatory preference with regard to the different dimensions of depth is best understood in terms of differing attitudes towards heuristics for future model building.

In possible scenarios on the origin of life, protocells represent the precursors of the first living cells. To study such hypothetical protocells, giant vesicles are being widely used as a simple model. Lipid vesicles can undergo complex morphological changes enabling self‐reproduction such as growth, fission, and extra‐ and intravesicular budding. These properties of vesicular systems may in some way reflect the mechanism of reproduction used by protocells. Moreover, remarkable similarities exist between the morphological changes observed in giant vesicles and bacterial (...) L‐form cells, which represent bacteria that have lost their rigid cell wall, but retain the ability to reproduce. L‐forms feature a dismantled cellular structure and are unable to carry out classical binary fission. We propose that the striking similarities in morphological transitions of L‐forms and giant lipid vesicles may provide insights into primitive reproductive mechanisms and contribute to a better understanding of the origin and evolution of mechanisms of cell reproduction.Editor's suggested further reading in BioEssays Synthesizing artificial cells from giant unilamellar vesicles: State‐of‐the art in the development of microfluidic technology Abstract.
