The idea of objectivity is primary in Gottlob Frege’s thought, not only for his conception of logic and mathematics, but also for his philosophy as a whole. He deals with the topic for the first time in 1884, in Grundlagen der Arithmetik, precisely in paragraph 26. He distinguishes the objective from the subjective, of course, but also from the real, what he calls the actual (wirklich in German). In order to be perfectly understood, he gives as example the colors but, (...) above all, to explain what is objective in geometry and space, he proceeds to a «thought-experiment», founded on the principle of duality. It is this aspect that I emphasize here, in the general framework ofparagraph 26 and in conjunction with Frege’s other works. (shrink)

We determine the consistency strength of the negation of the transversal hypothesis. We also study other variants of Chang's conjecture.

Devant le constat du déclin toujours plus rapide de la diversité biologique et les limites des res- sources disponibles pour l’enrayer, il est nécessaire de déterminer quels moyens devraient être engagés dans sa protection. Pour ce faire, une méthode efficace serait d’évaluer les bénéfices tirés de la biodiversité afin d’estimer rationnellement les coûts légitimes de sa protection. L’évaluation économique, qui se présente d’emblée sur un mode quantitatif, serait alors un outil précieux. Dans ce texte, nous présentons différentes méthodes d’évaluation économique (...) de la biodiversité ainsi que certaines de leurs limites méthodologiques. Par la suite, nous montrons qu’en dépit de ses avantages pratiques, l’évaluation économique échoue à représenter l’ensemble des valeurs en jeu dans la protection de la biodiversité. Nous décrivons alors trois types de valeurs incommen- surables avec des bénéfices économiques : la valeur de legs, qui renvoie aux obligations de trans- mission du patrimoine naturel dont nous avons hérité ; la valeur d’existence, qui renvoie à la considération morale d’intérêts autres que ceux des êtres humains ; la valeur de transformation, qui renvoie à la capacité d’examiner et de critiquer nos préférences et inclinaisons afin d’inclure celles-ci dans une vision du monde rationnelle et cohérente. Pour conclure, nous plaidons en faveur de l’élaboration de méthodes de concertation et d’évaluation participatives et pluralistes permettant de rendre compte de la diversité et de l’hétérogénéité des valeurs de la biodiversité.

If such a thing as nanoethics is possible, it can only develop by confronting the great questions of moral philosophy, thus avoiding the pitfalls so common to regional ethics. We identify and analyze some of these pitfalls: the restriction of ethics to prudence understood as rational risk management; the reduction of ethics to cost/benefit analysis; the confusion of technique with technology and of human nature with the human condition. Once these points have been clarified, it is possible to take up (...) some weighty philosophical and metaphysical questions which are not new, but which need to be raised anew with respect to nanotechnologies: the artificialization of nature; the question of limits; the role of religion; the finiteness of the human condition as something with a beginning and an end; the relationship between knowledge and know-how; the foundations of ethics.

Durante cuatro siglos, cristianos (de rito romano o visigótico), musulmanes y judíos coexistieron en la ciudad de Toledo. Pero tal coexistencia, antes de terminar de manera trágica, se caracterizó por muchos matices y atravesó circunstancias diversas. Cuando los llamados mozárabes (cristianos arabizados de rito visigótico) se fundieron en la masa cristiana de rito latino y lengua hispánica, después de dominar en la ciudad durante largo tiempo, los musulmanes (mudéjares), nunca muy numerosos, alcanzaron cierto apogeo en el siglo XIV, antes de (...) quedar parcialmente marginalizados en el XV. En cuanto a los judíos, debido al papel que desempeñaban en la gestión del dinero, fueron objeto de la ira y el furor popular, sobre todo en los siglos XIV y XV, incluso después de su conversión, fingida o sincera, a la fe cristiana.

Jean-Paul Sartre: Mind and Body, Word and Deed celebrates Sartre's polyvalence with an examination of Sartrean philosophy, literature, and politics. In four distinct yet related sections, twelve scholars from three continents examine Sartre's thought, writing and action over his long career. "Sartre and the Body" reappraises Sartre's work in dialogue with other philosophers past and present, including Maine de Biran, Maurice Merleau-Ponty and Didier Anzieu. "Sartre and Time" offers a first-hand account by Michel Contat of Sartre and Beauvoir working (...) together, and a "philosophy in practice" analysis by François Noudelmann. "Ideology and Politics" uses Sartrean notions of commitment and engagement to address modern and contemporary politics, including insights into Castro, De Gaulle, Sarkozy and Obama. Finally, an important but neglected episode of Sartre's life the visit that he and Beauvoir made to Japan in 1966 is narrated with verve and humour by Professor Suzuki Michihiko, who first met Sartre during that visit and remained in touch subsequently. Taken together, these twelve chapters make a strong case for the continued relevance of Sartre today. (shrink)

This paper first queries what type of concept of emergence, if any, could be connected with the different chemical activities subsumed under the label ‘quantum chemistry’. In line with Roald Hoffmann, we propose a ‘rotation to research laboratory’ in order to point out how practitioners hold a molecular whole, its parts, and the surroundings together within their various methods when exploring chemical transformation. We then identify some requisite contents that a concept of emergence must incorporate in order to be coherent (...) from the standpoint of the scientific practices involved. In this respect, we finally propose a relational form of emergence which pays attention to the constitutive role of the modes of intervention and to the co-definition of the levels of organization. No metaphysical distinction between the higher and basic levels of organization is supposed, but only a plurality of modes of access. Moreover, these modes of access are not construed as mere ways of revealing intrinsic patterns of organization but, on the contrary, are considered to be active elements on which the constitution of those patterns depends. What is at stake in this paper is therefore not an ontological form of emergence but an agnostic one which fits what chemists do in their daily work. (shrink)

This book questions the notions of person, personality, dignity, and other connected notions such as consent, and discusses new perspectives on categories that allow ethical debates in medicine to overcome morals and ordinary religious schemes. The book states that one has to be careful when thinking about situations in terms of notions and principles that have been obtained in similar situations. Though this book is mostly philosophical, it is also of great practical interest to healthcare givers. It warns caregivers not (...) to rely too much on notions such as person, autonomy, and consent, which are supposedly firm but can be proven to be unreliable in spite of appearances. Furthermore, this work warns against a narrow anthropologisation of ethics which would make technophobian positions unavoidable. On the contrary, this book is open to robotics and offers – among other things - a sustained exploration of the notion of intimacy. (shrink)

Starting from a nonlinear relativistic Klein-Gordon equation derived from the stochastic interpretation of quantum mechanics (proposed by Bohm-Vigier, (1) Nelson, (2) de Broglie, (3) Guerra et al. (4) ), one can construct joint wave and particle, soliton-like solutions, which follow the average de Broglie-Bohm (5) real trajectories associated with linear solutions of the usual Schrödinger and Klein-Gordon equations.

« Toute activité se laisse discerner et définir dans la mesure où elle prend forme, où elle inscrit sa courbe dans l’espace et le temps. La vie agit essentiellement comme créatrice de formes. La vie est forme, et la forme est le mode de la vie » (Henri Focillon). Formes de la géométrie et du cosmos, formes de la vie et de la pensée, formes architecturales, musicales et littéraires, formes fixes ou métamorphoses : le concept de forme est omniprésent dans (...) les sciences et dans les arts. C’est à une exploration de cette notion de forme que le Collège de France a consacré en octobre 2011 son colloque multidisciplinaire de rentrée : sa définition en philosophie chez Platon et Aristote, ses applications en mathématiques et en astrophysique, en chimie et en biologie, ses conséquences en psychologie et en linguistique, en anthropologie, en droit et dans les arts. Ces débats ont été aussi l’occasion de se tourner vers des pensées où elle joue un rôle particulièrement important, comme le structuralisme de Claude Lévi-Strauss ou l’histoire de l’art d’André Chastel.

La théorie du Contróle du Métabolisme décrit comment un réseau métabolique répond à de petites perturbations au voisinage d'un état stationnaire. Deux types de coefficients sont définis: les coefficients d'élaslicité qui quantifient les variations des vitesses des étapes isolées et les coefficients de contrôle qui expriment la réponse globale du réseau aux perturbations d'une étape donnée. Des relations entre ces coefficients existent ).On ne fait pas toujours la distinction entre Contrôle et Régulation. En fait, il apparait que la notion de (...) régulation, si elle est trés claire lorsqu'il s'agit de la régulation de l'activité d'un enzyme, West plus du tout définie lorsqu'il s'agit d'un réseau métabolique dans son ensemble.Le but de l'exposé est de proposer une définition de la régulation d'un réseau métabolique et de montrer quelles relations peuvent exister entre lee phénomènes de régulation et la théorie du contrôle du métabolisme.Quelques exemples seront donnés pour illustration.

Background: The 21-item Nurses’ Moral Courage Scale was developed and validated in 2018 in Finland with the purpose of measuring moral courage among nurses. Objectives: The objective of this study was to make a Dutch translation of the Nurses’ Moral Courage Scale to describe the level of nurses’ self-assessed moral courage and associated socio-demographic factors in Flanders, Belgium. Research design: A forward–backward translation method was applied to translate the English Nurses’ Moral Courage Scale to Dutch, and a pilot study was (...) conducted to improve readability and understandability. A non-experimental, descriptive cross-sectional exploratory design was used to conduct a survey. Descriptive analysis was used. Participants: The data were collected from a convenience sample of 559 nurses from two hospitals in Flanders. Ethical considerations: Ethical approval was obtained from the university ethics committee, permission to conduct the study was obtained from the participating hospitals. Participants received a guide letter and gave their informed consent. Findings: The readability and understandability of the Dutch Nurses’ Moral Courage Scale were positively evaluated, and the scale revealed a good level of internal consistency for the total scale (α =.914) and all subscales. Nurses’ mean score of the 21-item Nurses’ Moral Courage Scale was 3.77 (standard deviation = 0.537). The total Nurses’ Moral Courage Scale score was associated with age (p <.001), experience (p <.001), professional function (p =.002), level of education (p =.002) and personal interest (p <.001). Discussion and Conclusion: The Nurses’ Moral Courage Scale was successfully translated to Dutch. The Flemish nurses perceived themselves as morally courageous, especially when they were in a direct interpersonal relationship with their patients. Acting courageously in ethical dilemmas that involved other actors or organizations appeared to be more challenging. The results strongly suggest the important role of education and ethical leadership in developing and supporting this essential virtue in nursing practice. (shrink)

Jean-Pierre Dupuy a tenu pendant la pandémie un « journal de pensée » d'un genre spécial : il réagit moins aux événements que nous avons tous vécus depuis le mois de mars 2020 qu'à la manière dont ces événements ont été analysés, discutés. Il le fait à la lumière de sa contribution majeure à la pensée de la catastrophe développée dans un livre fameux et souvent mal compris, Pour un catastrophisme éclairé. Quand l'impossible est certain (Seuil, 2002 ; (...) 2004). Voici un livre de combat mû par la colère. La colère de voir des intellectuels relativiser la gravité de la pandémie en cours, s'engager dans une critique virulente de sociétés et de gouvernants qu'ils jugent obsédés par la « protection de la vie », au point de sacrifier l'avenir du monde, de l'économie et des libertés publiques. Avec rigueur et détermination, Jean-Pierre Dupuy leur répond et met au jour les erreurs logiques - et scientifiques - qui sous-tendent ces raisonnements, et propose par là même une réflexion passionnante et passionnée sur la mort et la vie au temps de la pandémie."--Page 4 of cover.

Résumé Dans Nécessité ou contingence, l’un des plus grands livres de Jules Vuillemin, on découvre que, bien avant les premiers calculs « réussis » au XVIIe siècle sur les probabilités, un terrain était mis en place pour les penser fondamentalement selon les divisions mêmes qui traverseront leur notion jusqu’à notre époque. Sortis de leur gangue historique, les problèmes sont élevés à quelque pureté logique. Une chose surprend alors : ainsi dégagés de toute situation réelle, les thèmes probabilistes consonnent avec des (...) problèmes éthiques qui se posaient aux auteurs à chaque époque, mais aussi dans les années 1980 aux hommes qui s’affairaient aux problèmes de bioéthique. Vuillemin reste silencieux sur ce type d’application. Redoutable critique des positions « existentialiste », on le voit, paradoxalement, sous l’effet de sa réflexion touchant les probabilités, s’accorder avec Merleau-Ponty sur des positions importantes, alors que cette réflexion est totalement absente de l'oeuvre de son prédécesseur au Collège de France.

Prosocial compensation is a corporate social responsibility practice that involves donating money to a charitable cause on behalf of customers as a means to compensate them for their loss after a service failure. In order to determine the effectiveness of PC, we carried out three experiments while also comparing its effectiveness within private and public settings. Experiment 1 focused on the signaling effects of communicating the promise to offer PC to potential customers in the event of service failure. Results show (...) that, in both private and public settings, PC has positive effects on corporate image, credibility, and word-of-mouth intent. More significantly, PC improved one’s CSR image, whereas more tangible compensation, such as a gift voucher, did not. Experiments 2A and 2B focused on the effects of offering PC after a service failure on perceptions of justice. Results show that PC contributes to perceived distributive justice, procedural justice, and post-recovery satisfaction in both private and public settings. Our study showed that PC could be a relevant new CSR practice for organizations wanting to enhance theirs CSR image while contributing to fulfilling their ethical and philanthropic CSR responsibilities. We discuss the implications of our findings and offer several avenues for follow-up research on this initial study on PC. (shrink)

Chemists do not aim at testing preconceptions or theoretical hypotheses only; they first and foremost produce and determine the object of chemical investigation: they learn through making. They never cease to create and stabilize heterogeneous devices, methods, models, and theories in order to act upon the world. Chemical bodies cannot be studied in isolation; their properties constitutively depend on what surrounds and acts upon them. Starting from the specificity of chemical practices, this paper investigates the meaning of consistency, inconsistency, and (...) that of the ceteris paribus clause, in this domain of science. In so doing, it defends the idea that studying what we call ‘a lack of consistency’ should always include the scrutiny of: the way a particular scientific practice is stabilized, and the ontological or pragmatic assumptions about the entities and processes upon which this practice revolves.

The myth of an economy where nobody could have a predominant position, has lost its credibility. The presentiment of a high risk of social explosion makes companies undertake tentative moral legitimation. Thus, a new paradigm develops according to which the firm has to care for the satisfaction of public interest if it wants to try to win forgiveness for misbehavior towards the decorum rules of the atomicity of competition. Thus, there is a wave of business ethics industry building up. However, (...) the stock exchange performances considered as ethical, are not different from others! The market does not seem to be able to say why it might be interesting to invest in stock considered as ethical. Moreover, opinion polls reveal a very significant discrepancy between the characterization of the responsible company as defined by itself or by notation agencies and, on the other hand, the hierarchy of criteria according to the answers of polled people. When companies and agencies favor sustainable development and good governance, rejecting child labor and so on, polled people consider that the paramount criterion of ethical conduct is personnel management. The problem is right here. Such is the view of a positively critical economist, situated at the point where macroeconomics meets corporate management. (shrink)

Les grands paradigmes des sciences humaines ont été constitués, au fil de l’histoire, par l’éviction progressive de la dimension affective des objets et méthodes scientifiques. Après un long désintérêt, pour partie dû à la préoccupation de l’objectivation des phénomènes retenus par l’analyse sociologique, mais aussi à l’hypostase du social, qui a trouvé notamment chez Durkheim un accomplissement encore plus accentué que dans la plupart des conceptions holistes, la question des émotions est l’...

An examination of the fundamental role cybernetics played in the birth of cognitive science and the light this sheds on current controversies. The conceptual history of cognitive science remains for the most part unwritten. In this groundbreaking book, Jean-Pierre Dupuy—one of the principal architects of cognitive science in France—provides an important chapter: the legacy of cybernetics. Contrary to popular belief, Dupuy argues, cybernetics represented not the anthropomorphization of the machine but the mechanization of the human. The founding fathers (...) of cybernetics—some of the greatest minds of the twentieth century, including John von Neumann, Norbert Wiener, Warren McCulloch, and Walter Pitts—intended to construct a materialist and mechanistic science of mental behavior that would make it possible at last to resolve the ancient philosophical problem of mind and matter. The importance of cybernetics to cognitive science, Dupuy argues, lies not in its daring conception of the human mind in terms of the functioning of a machine but in the way the strengths and weaknesses of the cybernetics approach can illuminate controversies that rage today—between cognitivists and connectionists, eliminative materialists and Wittgensteinians, functionalists and anti-reductionists. Dupuy brings to life the intellectual excitement that attended the birth of cognitive science sixty years ago. He separates the promise of cybernetic ideas from the disappointment that followed as cybernetics was rejected and consigned to intellectual oblivion. The mechanization of the mind has reemerged today as an all-encompassing paradigm in the convergence of nanotechnology, biotechnology, information technology, and cognitive science. The tensions, contradictions, paradoxes, and confusions Dupuy discerns in cybernetics offer a cautionary tale for future developments in cognitive science. (shrink)
