In lieu of an abstract, here is a brief excerpt of the content:Preface: Virtual Entities in ScienceRobert Harlander, Jean-Philippe Martinez, Friedrich Steinle, and Adrian WüthrichIt is not only since the sudden increase of online communication due to the COVID-19 situation that the concept of the “virtual” has made its way into everyday language. In this context, it mostly denotes a digital substitute for a real object or process. Virtual reality is perhaps the best-known term in this respect. With (...) these digital connotations, “virtuality” has also been used in science and research: Chemists use virtual laboratories, biologists do virtual scanning of molecular structures, and geologists engage in virtual field trips. But the concept of the virtual has a much longer tradition, dating back to long before the dawn of the digital age. Virtual images and virtual displacements were introduced in classical physics already in the late seventeenth and eighteenth centuries, respectively. They represent auxiliary objects or processes without instantiation, with the purpose of efficiently describing specific physical systems. In today’s physics, the term “virtual” is mostly associated with the quantum world, first and foremost with the “virtual particle” of quantum field theory. It has become such an integral part of modern high energy physics that its ontological character may be considered to go beyond the purely auxiliary, which is typically associated with the virtual. [End Page 263]In other disciplines, however, use of the term virtual without a digital connotation is much rarer. While concepts like “virtual adrenaline” show up in physiological research around 1940s, and Charles Darwin, in a private note in January 1840,1 spoke of “virtual change” in the context of embryology, these examples seem to be singular occurrences of entities that were explicitly called “virtual.” The basic idea behind the terminology of the virtual, however, might be much more common, even outside of physics. The “invisible hand” in economics, or the “vital force” in biology, for instance, may carry aspects of a virtual entity, even if they have not been referred to that way.These different observations raise several questions about the status of virtual entities in science. What has led scientists to call one entity “virtual” and not another? Do all virtual entities in science have the same roots and meet the same characteristics? Are they more than auxiliary objects or processes? Why does physics seem to occupy a specific position with respect to the use of the notion of virtuality? These are some points that led us to discuss virtual entities in science during a workshop, out of which grew the present collection. We invited contributions that addressed the historical formation and philosophical interpretation of concepts of virtual entities in physics and other disciplines—in whatever terms they may come. The main goal of the workshop was to bring to the fore similarities and differences in the meanings and functions of these concepts, so as to be able to precisely characterize why certain entities are considered virtual in specific contexts, why a different terminology was often used in each individual case, and in what sense the virtual entities relate to the real world.The organization of the workshop was part of our project “The formation and development of the concept of virtual particles,” a subproject of the Research Unit “The Epistemology of the Large Hadron Collider,” funded by the Deutsche Forschungsgemeinschaft (DFG) and Der Wissenschaftsfonds (FWF). The workshop took place online on four consecutive Fridays in March 2021. It brought together contributors who discussed the role of the concept of the virtual in theoretical as well as experimental activities, and investigated into the origins of the terminology of the virtual as it was applied to the various disciplines of natural science. Dealing with historical, philosophical, but also methodological questions, the presentations covered a wide time range, from the Middle Ages to the present day. While physics naturally emerged as the dominant field, natural philosophy, computer science and biology were also addressed. The papers in this volume were contributed by participants in this workshop and approach the subject from different angles. [End Page 264]First, Friedrich Steinle provides us with an introductory piece that reflects on the specific meaning of the use of the term ‘virtual’ in science. He highlights and... (shrink)

Jean-Philippe Perreault | : Au point de départ de cette réflexion sur l’innovation religieuse, deux considérations : d’une part, il existe nécessairement de la nouveauté et de la créativité religieuses dans la mesure où les religions évoluent, s’adaptent et demeurent vivantes ; d’autre part, la jeunesse est elle-même pensée et construite comme source de nouveauté et de progrès. L’innovation religieuse se trouve conséquemment au centre du thème de recherche « jeunes et religions ». Sous forme de « notes (...) de recherche », l’intention ici est d’identifier quelques repères permettant une problématisation de la question de l’innovation religieuse dans l’étude du rapport des jeunes aux religions. Pour ce faire, nous interrogerons les conditions d’une telle innovation, tant sur le plan empirique qu’épistémologique : de quelle innovation est-il question, qui innove et innove en regard de quoi? Quelle épreuve épistémologique devrions-nous faire subir aux principaux concepts pour nous assurer de leur opérationnalité, de leur fécondité et de leur scientificité pour nos travaux? | : At the starting point of this reflection on religious innovation, there are two considerations : on the one hand, there is necessarily novelty and religious creativity insofar as religions evolve, adapt and remain alive ; on the other hand, youth is itself thought and constructed as a source of novelty and progress. Therefore, religious innovation is at the center of the research theme “youth and religions”. In the form of “research notes”, the intention here is to identify a few benchmarks that allow a problematization of religious innovation question in the study of relationship between young people and religions. To do so, we will question the conditions for such an innovation, both empirically and epistemologically : what innovation is in question, who innovates and innovates compared to what? What epistemological test should the main concepts undergo to ensure their operationality, their fertility and their scientificity for our work? (shrink)

In this essay, I take up James Conant and Cora Diamond’s suggestion that “to take the difference between saying and showing deeply enough is not to give up on showing but to give up on picturing it as a ‘what’ ”. I try to establish that the Tractatus’s talk of “showing” is more coherent than is usually appreciated, that it is indeed a key to the internal unity of the book, and that it positively helps us to work our way (...) into the practice of philosophy, which its author understood as a practice of logical clarification. Thus, it is not a stretch of latent nonsense whose sole function is to conjure up an illusion of sense for the sake of displaying its disintegration. While Wittgenstein’s concept of showing is not meant to “make up for” the impossibility of saying certain things, neither does it stand in need of being “redeemed.” Whether or not it is to prove ultimately coherent, the Tractatus’s talk of “showing,” I shall argue, is certainly not to be “thrown away” in the name of the Tractarian conception of logic, for the simple reason that it essentially belongs with it.

Loin d’être un auteur mineur, thuriféraire d’un naïf “laissez-faire”, Bastiat apparaît comme le précurseur de la plupart des courants libéraux contemporains.Il est frappant de constater que le diagnostic porté par Bastiat sur le fonctionnement de la démocratie demeure d’une brûlante actualité.C’est donc injustement que Hayek a méconnu son devancier : une étude critique de la philosophie juridique et politique du Français lui aurait permis d’éviter quelques inconséquences, telle sa théorie des fonctions non coercitives de l’Etat.Far from being a minor economist, (...) or flattering some naive “laissez-faire”, Bastiat is indeed a precursor of most of the contemporaneous views defending liberalism.It is striking to note how much Bastiat’s diagnosis about the workings of democracy applies with acuity to the current world.Thus, Hayek unduly disregarded his precursor: a critical study of Bastiat’s philosophy and conception of law would have allow Hayek to not fall into some traps, such as his theory on the non-coercitive functions of government.

Critiquer la Déclaration universelle des droits de l’homme du 10 décembre 1948 paraît relever de la provocation ou de l’inconscience. Ses contempteurs, qu’il s’agisse des marxistes ou des conservateurs, se sont déconsidérés. Nonobstant, c’est avec force courage que Hayek s’est attelé dès 1966 à une critique en règle de cette déclaration “constructiviste” dont l’objectif impossible était de fusionner les droits de la tradition libérale avec ceux de la conception marxiste. Le Prix Nobel démontre que les nouveaux droits ainsi proclamés ne (...) peuvent être traduits dans des lois contraignantes sans détruire incontinent l’ordre de liberté auquel tendent les droits “traditionnels” : la Déclaration constitue l’un de ces instruments qui oeuvrent à la dévalorisation du Droit et partant à la destruction de la Liberté. C’est par son prestige et par l’ignorance de ceux qui l’ont exploité que ce texte a pu prospérer. Son seul mérite est de mériter l’oubli.It might seem provocative or inconsistent to criticize the Universal Declaration of Human Rights of December 10, 1948. Its detractors, whether they be Marxists or Conservatives have fallen into discredit. Notwithstanding, Hayek has courageously tried to criticize this “constructivist” piece whose impossible goal was to unite rights in the liberal tradition with those pertaining to the Marxist conception. Hayek shows that the new rights which are proclaimed in this fashion cannot be translated into juridical constraints without destroying forthwith the liberal order cherished by “traditional” rights: the Universal Declaration of Human Rights is one of the tools which enhances the depreciation of Law and, by the way, the annihilation of Freedom. This text has flourished thanks to its prestige and to the ignorance of those who have employed it. Its unique merit is to deserve oblivion. (shrink)

Jean-Philippe Pierron | : Dans leur réflexion sur le raisonnement moral, critique d’une approche rationaliste stricte, les théories du care et les philosophies travaillant à une compréhension enrichie de la raison pratique se sont attachées à mettre en valeur l’importance éthique qu’il y a à envisager la perspective de l’autre. Elles se sont concentrées à cette fin sur le travail de l’imagination. On montre ici que l’éthique du care de Gilligan, l’éthique de la narration de Nussbaum et l’éthique (...) de la sollicitude ricoeurienne, quoique différentes, se renforcent mutuellement à partir d’une compréhension renouvelée du rôle de l’imagination dans la morale. Si l’enquête psychologique de Gilligan, la philosophie de la littérature chez Nussbaum et l’herméneutique du texte chez Ricoeur diffèrent, ces trois auteur.es ont en commun de ne pas se satisfaire des méfaits d’une rationalité instrumentale qui bride la créativité pratique des actrices morales et acteurs moraux. Il appartiendrait à l’imagination éthique de prendre la mesure de la complexité des situations morales et d’en suivre les variations subtiles, afin de prendre soin de formes de vies rendues invisibles ou d’existences vulnérables. | : Critical of a strictly rationalist approach, theories of care and philosophies working toward a deeper understanding of practical reason have valorized the ethical importance of envisioning the perspective of the other in their reflection on moral reasoning. To this end, they have focussed on the task of the imagination. Here it is shown that, however different, Gilligan’s ethics of care, Nussbaum’s narrative ethics, and Ricoeur’s ethics of solicitude mutually reinforce each other through a renewed comprehension of the role of the imagination in the philosophy of action. Although Gilligan’s psychological investigation, Nussbaum’s philosophy of literature, and Ricoeur’s textual hermeneutics differ, these three authors have something in common: a discontent with the misdeeds of an instrumental rationality that shackles the practical creativity of moral actors. It is up to the ethical imagination to size up the complexity of moral situations and to appreciate their subtle variations, in order to take care of forms of life made invisible and vulnerable existences.

The confluence of protein engineering techniques and delivery protocols are providing new opportunities in cell biology. In particular, techniques that render the membrane of cells transiently permeable make the introduction of nongenetically encodable macromolecular probes into cells possible. This, in turn, can enable the monitoring of intracellular processes in ways that can be both precise and quantitative, ushering an area that one may envision as cellular biochemistry. Herein, the author reviews pioneering examples of such new cell‐based assays, provides evidence that (...) challenges the paradigm that cell penetration is a necessarily damaging and stressful event for cells, and highlights some of the challenges that should be addressed to fully unlock the potential of this nascent field.

While examining the reception given by the media to the World Youth Day held in July 2002 in Toronto (Canada) as well as their promotion of the event, the author tries to draw the profile of the youth, and its links with catholic religion. The analysis of press articles published into two important Quebec daily newspapers allows the identification of different visions of the youth put forward by the media. It can be noticed that the emphasis put on youth heterogeneity (...) at the beginning quickly moves to the presentation of a homogeneous youth united around Pope John-Paul II. However, such a relation of youth toward Catholicism goes against research major conclusions on this topic. To this reception of the WYD by Quebec media, several explanations about, among others, mass media status, role, and functioning in our society are proposed. (shrink)

Si une pensée a autant de coordonnées intrinsèques qu'a de dimensions catégoriales le système de variantes qu'elle « instantie », alors l'exemplarité de chacune de ses coordonnées est totalement fixée par les dimensions de ce système et cette pensée se laisse adéquatement exprimer selon l'axe longitudinal unique d'une pro-position posant ses coordonnées comme autant de substitutions effectuées sur les variables de catégories. Mais, inversement, si aucune pensée ne se laisse adéquatement caractériser par des coordonnées qui lui seraient intrinsèques, et si (...) une pensée n'ade coordonnées que relativement aux systèmes auxquels elle peut être corrélée selon le contexte à la faveur de sa juxtaposition avec d'autres pensées, alors ce dont ses coordonnées sont exemplaires paraîtra indéterminé aussi longtemps qu'on exprimera cette pensée dans une proposition, c'est-à-dire abstraction faite des dimensions selon lesquelles elle est coordonnée. Nous voudrions montrer ici, sur le cas des preuves mathématiques, que la comparaison par Wittgenstein des preuves mathématiques à des paradigmes fait précisément pièce à cette seconde possibilité.

On se propose de montrer que l’écart entre les critiques heideggérienne et wittgensteinienne de l’adoption du point de vue logique sur le sens et l’écart entre leurs conceptions respectives de la sensibilité du sens au contexte deviennent visibles et intelligibles à partir du moment où ils sont rapportés l’un à l’autre. On cherchera la clé de ce double écart dans un désaccord fondamental des deux philosophes sur le sort qui peut et doit être fait à l’usage philosophique du petit mot (...) « qua », usage qui semble aussi ancien que la métaphysique elle-même.The paper aims at showing that both the gulf between Heidegger’s and Wittgenstein’s respective ways of inveighing against the prevailing of a logical point of view upon sense, and the gulf between their respective accounts of the context-sensitivity of sense, can be at once brought to light and rendered intelligible by being aligned on each other. It is contended that both of these clashes hinge upon a fundamental disagreement as to what could and should be made of the traditional use in metaphysics of the little word « als », in a word, of its use as « qua ».

In this paper, we propose a framework capable of dealing with anaphora and ellipsis which is both general and algorithmic. This generality is ensured by the compination of two general ideas. First, we use a dynamic semantics which reperent effects using a monad structure. Second we treat scopes flexibly, extending them as needed. We additionally implement this framework as an algorithm which translates abstract syntax to logical formulas. We argue that this framework can provide a unified account of a large (...) number of anaphoric phenomena. Specifically, we show its effectiveness in dealing with pronominal and VP-anaphora, strict and lazy pronouns, lazy identity, bound variable anaphora, e-type pronouns, and cataphora. This means that in particular we can handle complex cases like Bach–Peters sentences, which require an account dealing simultaneously with several phenomena. We use Haskell as a meta-language to present the theory, which also consitutes an implementation of all the phenomena discussed in the paper. To demonstrate coverage, we propose a test suite that can be used to evaluate computational approaches to anaphora. (shrink)

This paper investigates a particular philosophical puzzle via an examination of its status in the writings of Wittgenstein. The puzzle concerns negation and can take on three interrelated guises. The first puzzle is how not-p can so much as negate p at all – for if p is not the case, then nothing corresponds to p. The second puzzle is how not-p can so much as negate p at all when not-p rejects p not as false but as unintelligible – (...) for if p is unintelligible, then p is nothing but scratches and sounds and does not seem apt for negation. And the third puzzle is how “not” could be anything but hopelessly equivocal if it sometimes (per the first puzzle) requires, and sometimes (per the second puzzle) precludes the intelligibility of p. The paper investigates these three puzzles, their respective structures, and their relations to each other. The second puzzle is expounded as the centre of gravity, and in countering two objections to the threefold puzzle, a special predicament is expounded with regard to the second puzzle’s concern with unipolar propositions – propositions that do not admit of an intelligible negation. The text concludes by indicating the first steps that could potentially lead us out of the threefold puzzle. (shrink)

This article discusses the meaning of the notion of virtuality in modern physics. To this end, it develops considerations on the introduction and establishment in nuclear physics of two independent concepts at the turn of the 1920s and 1930s: that of the virtual state, used in the context of neutron scattering studies, and that of the virtual transition, useful for the theoretical understanding of strong nuclear forces, which forms the basis of what are now called virtual particles. Their comparative analysis (...) highlights the theoretical nature of virtual entities and processes in modern physics. It also shows how the virtual has been associated with various purely physical attributes, leading to a form of polysemy of the term, from the beginning of the application of these concepts.

In recent years, theorists have contended that we should move to a mode of social organisation where work and the values attached to it are no longer central, a ‘post-work society’. For these theorists, the modern ideology of work is intrinsically unjust, even irrational and no longer suited to the challenges of our time. The article presents an alternative response to the problems of work and employment. Rather than moving to a ‘post-work’ society, the article argues that we should transform (...) the world of work, precisely by keeping in view why working is important to individuals and the community. In fact, it is not realistic to believe that human societies could ever do without work. Because human societies are by necessity work societies, and work, if organised correctly, entails many goods, we cannot really, and we should not, wish work away. (shrink)

En résolvant au plan de l’attribution du nombre un problème insoluble au plan de l’engendrement du nombre, celui de la compatibilité entre égalité et discernabilité, Frege est conduit à supposer l’existence de concepts dont les caractères dépeignent des propriétés discriminantes. Frege souligne avec force que « donner un nombre, c’est exprimer un fait indépendant de notre manière de voir ». Mais on peut se demander si un caractère discriminant, précisément, n’est pas une « manière de voir » – quoiqu’au sens (...) non psychologiste d’un aspect sous lequel peut être vu un complexe signitif. Frege et Husserl méconnaissent que le procédé de spécification des multiplicités par mise en correspondance biunivoque est tributaire d’une extension de la théorie des moments figuraux aux complexes signitifs. En envisageant les nombres comme des propriétés internes de symboles de classes, en d’autres termes comme des aspects exhibés par des listes, Wittgenstein pense l’émergence de critères figuraux de corrélations numériques. Contre la critique frégéenne de Husserl, Wittgenstein fait valoir que la pertinence de la notion de moment figural ou d’aspect n’est pas confinée à la psychologie ; contre le thème husserlien d’une intuition catégoriale des nombres, que le moment statutaire du concept ne saurait être délégué à aucune intuition.

As social and ecological transition and climate change raise issues that go far beyond individual responses, how can these challenges be balanced with ethical and political responses? This article intends to show that the strength of virtue ethics lies in the fact that it translates these abstract issues into concrete biographical events that shape lifestyles. The search for the good life in these matters then finds in temperance, humility and hospitality three virtues, private and social, to operate this translation. Humility (...) makes explicit the deep interdependencies between the living, while temperance calls for practices that are attentive to these relationships, in the knowledge that our ways of life here have far-reaching consequences on the other side of the globe. This in turn invites us to restore hospitality to its cosmopolitical dimension. (shrink)

Without having directly tackled the question of ecology, the philosophical hermeneutics of Paul Ricœur offers nevertheless an original treatment of the phenomenological theme of “dwelling”. His hermeneutics of the “long path” underscores the fact that our environment is given to us in the form of tools, institutions and the values of historical communities. Whereas the global ecological crisis could easily give rise to a response that is inattentive to cultural diversity, Ricœur’s explicit attention to the question of what it means (...) to dwell on the earth within the symbolic universe of a culture invites us to think quite differently. Phenomenology makes possible a condensation of the human meaning of our belonging to the Earth; hermeneutics shows how this belonging can only take place within instituted environments. (shrink)
