The origin of the notochord is one of the key remaining mysteries of our evolutionary ancestry. Here, we present a multi‐level comparison of the chordate notochord to the axochord, a paired axial muscle spanning the ventral midline of annelid worms and other invertebrates. At the cellular level, comparative molecular profiling in the marine annelids P. dumerilii and C. teleta reveals expression of similar, specific gene sets in presumptive axochordal and notochordal cells. These cells also occupy corresponding positions in a conserved (...) anatomical topology and undergo similar morphogenetic movements. At the organ level, a detailed comparison of bilaterian musculatures reveals that most phyla form axochord‐like muscles, suggesting that such a muscle was already present in urbilaterian ancestors. Integrating comparative evidence at the cell and organ level, we propose that the notochord evolved by modification of a ventromedian muscle followed by the assembly of an axial complex supporting swimming in vertebrate ancestors.

Créée par Éric Rochant, Le Bureau des légendes (Canal +, 2015-2020) explore le monde du renseignement en décrivant le travail du service des agents clandestins de la DGSE. Face aux incertitudes et aux complexités géopolitiques du monde contemporain, elle fait le choix d’une immersion au cœur du « renseignement humain ». Cet article envisage l’hypothèse selon laquelle une telle fiction permet de restaurer la confiance des spectateurs vis-à-vis de la capacité d’une démocratie à lutter contre ce qui la menace. En (...) plongeant son spectateur dans les coulisses du renseignement, en le familiarisant avec des personnages complexes, la série questionne la légitimité de la confiance qu’il est possible d’accorder à un service de renseignement. La faillibilité des agents, mise en scène de façon détaillée, réfléchie par la série elle-même, rassure parce qu’elle permet de comprendre et de partager une forme de vie spécifique qui est celle de l’action secrète. L’espionnage, le contre-espionnage et le contre-terrorisme apparaissent alors comme des pratiques reposant en dernier ressort, non pas sur une maîtrise absolue, mais sur la décision de faire confiance ou au contraire de se méfier. Mobilisant les recherches de la sociologie contemporaine à propos de la confiance (Giddens, 1994 et Luhmann 2006), il s’agit de décrire Le Bureau des légendes comme une fiction projetant sur nos écrans, la possibilité d’une restauration de la confiance ou pour le dire à la manière de Stanley Cavell, une issue possible au scepticisme.

Kit Fine develops a Fregean theory of abstraction, and suggests that it may yield a new philosophical foundation for mathematics, one that can account for both our reference to various mathematical objects and our knowledge of various mathematical truths. The Limits ofion breaks new ground both technically and philosophically.

Most studies on verticality’s embodiment showed that up positions were related to positive emotions whereas down positions were related to negative ones. Research on motion perception found that a parabolic motion both induced animation attribution and implied negative feelings. We hypothesized that seeing a parabolic downward motion will increase both the memorization for words and the execution’s speed of a serial subtraction compared to a parabolic upward motion. Results showed that the downward motion had enhancing effects both on the serial (...) subtraction and on the number of recalled words, independently of their valence. These findings are interpreted as marking processes related to an adaptive behavior in response to a negative stimulus. (shrink)

Are there, in addition to the various actual objects that make up the world, various possible objects? Are there merely possible people, for example, or merely possible electrons, or even merely possible kinds? We certainly talk as if there were such things. Given a particular sperm and egg, I may wonder whether that particular child which would result from their union would have blue eyes. But if the sperm and egg are never in fact brought together, then there is no (...) actual object that my thought is about. Or again, in the semantics for modal logic we presuppose an ontology of possibilia twice over. For first, we countenance various possible worlds, in addition to the actual world; and second, each of these worlds is taken to be endowed with its own domain of objects. These will be the actual objects of the world in question, but they need not be actual simpliciter, i.e., actual objects of our world. What are we to make of such discourse? There are four options: (i) the discourse is taken to be unintelligible; (ii) it is taken to be intelligible but nonfactual, i.e. as not in the business of stating facts; (iii) it is taken to be factual but reducible to discourse involving no reference to possibilia; (iv) it is taken to be both factual and irreducible. These options range from a full-blooded form of actualism at one extreme to a full-blooded form of possibilism at the other. The two intermediate positions are possibilist in that they accept the intelligibility of possibilist discourse but actualist in that they attempt to dispense with its prima facie commitment to possibilia. All four positions have found advocates in the literature. Quine, in his less irenic moments, favours option (i); Forbes advocates option (ii), at least for certain parts of possibilist discourse; many philosophers, including Adams and myself, opt for (iii); while Lewis and Stalnaker have endorsed versions of (iv), that differ in how full-blooded they take the possible objects to be..

In quantum statistical mechanics, equilibrium states have been shown to be the typical states for a system that is entangled with its environment, suggesting a possible identification between thermodynamic and von Neumann entropies. In this paper, we investigate how the relaxation toward equilibrium is made possible through interactions that do not lead to significant exchange of energy, and argue for the validity of the second law of thermodynamics at the microscopic scale.

The purpose of this paper is to examine how any domain of Meinongian objects can be structured by a special kind of mereology. The basic definition of this mereology is the following: an object is part of another iff every characteristic property of the former is also a characteristic property of the latter. I will show that this kind of mereology ends up being very powerful for dealing with Meinongian objects. Mereological sums and products are not restricted in any way (...) in a domain of Meinongian objects: there is a sum and a product for any pair of Meinongian objects. With the mereological operations of sum, product and complement, and two special Meinongian objects, we can define a full boolean algebra on Meinongian objects. Moreover, this kind of mereology is atomic and extensional: an atom is a Meinongian object having just one characteristic property and two objects are identical iff the same atoms are parts of both of them. A Meinongian object can finally be defined in mereological terms as the sum of the atoms of its characteristic properties. (shrink)

Selections seeks to provide an accurate and readable translation that will allow the reader to follow Aristotle's use of crucial technical terms and to grasp the details of his argument. Unlike anthologies that combine translations by many hands, this volume includes a fully integrated set of translations by a two-person team. The glossary--the most detailed in any edition--explains Aristotle's vocabulary and indicates the correspondences between Greek and English words. Brief notes supply alternative translations and elucidate difficult passages.

In a first part, I defend that formal semantics can be used as a guide to ontological commitment. Thus, if one endorses an ontological view \(O\) and wants to interpret a formal language \(L\) , a thorough understanding of the relation between semantics and ontology will help us to construct a semantics for \(L\) in such a way that its ontological commitment will be in perfect accordance with \(O\) . Basically, that is what I call constructing formal semantics from an (...) ontological perspective. In the rest of the paper, I develop rigorously and put into practice such a method, especially concerning the interpretation of second-order quantification. I will define the notion of ontological framework: it is a set-theoretical structure from which one can construct semantics whose ontological commitments correspond exactly to a given ontological view. I will define five ontological frameworks corresponding respectively to: (i) predicate nominalism, (ii) resemblance nominalism, (iii) armstrongian realism, (iv) platonic realism, and (v) tropism. From those different frameworks, I will construct different semantics for first-order and second-order languages. Notably I will present different kinds of nominalist semantics for second-order languages, showing thus that we can perfectly quantify over properties and relations while being ontologically committed only to individuals. I will show in what extent those semantics differ from each other; it will make clear how the disagreements between the ontological views extend from ontology to logic, and thus why endorsing an ontological view should have an impact on the kind of logic one should use.

Plato on Knowledge and Forms brings together a set of connected essays by Gail Fine, in her main area of research since the late 1970s: Plato's metaphysics and epistemology. She discusses central issues in Plato's metaphysics and epistemology, issues concerning the nature and extent of knowledge, and its relation to perception, sensibles, and forms; and issues concerning the nature of forms, such as whether they are universals or particulars, separate or immanent, and whether they are causes. A specially written (...) introduction draws together the themes of the volume, which will reward the attention of anyone interested in Plato or in ancient metaphysics and epistemology. (shrink)

Children’s reasoning on food properties and health relationships can contribute to healthier food choices. Food properties can either be positive (“gives strength”) or negative (“gives nausea”). One of the main challenges in public health is to foster children’s dietary variety, which contributes to a normal and healthy development. To face this challenge, it is essential to investigate how children generalize these positive and negative properties to other foods, including familiar and unfamiliar ones. In the present experiment, we hypothesized that children (...) might rely on cues of food processing (e.g., signs of human intervention such as slicing) to convey information about item edibility. Furthermore, capitalizing on previous results showing that food rejections (i.e., food neophobia and picky eating) are a significant source of inter-individual variability to children’s inferences in the food domain, we followed an individual approach. We expected that children would generalize the positive properties to familiar foods and, in contrast, that they would generalize more often the negative properties to unfamiliar foods. However, we expected that children would generalize more positive and less negative properties to unfamiliar sliced foods than to whole unfamiliar foods. Finally, we expected that children displaying higher levels of food rejections would generalize more negative properties than children displaying lower levels of food rejections. One-hundred and twenty-six children, aged 3–6 years, performed an induction task in which they had to generalize positive or negative health-related properties to familiar or unfamiliar foods, whole or sliced. We measured children’s probability of generalization for positive and negative properties. The children’s food rejection score was assessed on a standardized scale. Results indicated that children evaluated positively familiar foods (regardless of processing), whereas they tend to view unfamiliar food negatively. In contrast, children were at chance for processed unfamiliar foods. Furthermore, children displaying higher levels of food rejections were more likely to generalize the negative properties to all kinds of foods than children displaying lower levels of food rejections. These findings entitle us to hypothesize that knowledge-based food education programs should take into account the valence of the properties taught to children, as well as the state of processing of the food presented. Furthermore, one should take children’s interindividual differences into account because they influence how the knowledge gained through these programs may be generalized. (shrink)

Establishing healthy dietary habits in childhood is crucial in preventing long-term repercussions, as a lack of dietary variety in childhood leads to enduring impacts on both physical and cognitive health. Poor conceptual knowledge about food has recently been shown to be a driving factor of food rejection. The majority of studies that have investigated the development of food knowledge along with food rejection have mainly focused on one subtype of conceptual knowledge about food, namely taxonomic categories. However, taxonomic categorization is (...) not the only way to understand the food domain. We also heavily rely on other conceptual structures, namely thematic associations, in which objects are grouped because they share spatial-temporal properties or exhibit a complementary relationship. We rely on such thematic associations between food items, which may not fall into the same taxon, to determine the acceptability of food combinations. However, the development of children's ability to master these relations has not been systematically investigated, nor alongside the phenomenon of food rejection. The present research aims to fill this gap by investigating the development of conceptual food knowledge and the putative relationship between children's food rejection and both thematic and taxonomic food knowledge. A proportional analogy task, with a choice between taxonomic and thematic food associates, was conducted on children between 3 and 7-years-old. The children were systematically presented with either a thematic or taxonomic food base pair and then asked to extend the example type of relation to select the respective thematic or taxonomic match to the target. Our results revealed, for the first time, that increased levels of food rejection were significantly predictive of poorer food identification and decreased thematic understanding. These findings entitle us to hypothesize that knowledge-based food education programs to foster dietary variety in young children, should not only aim to improve taxonomic understanding of food, but also thematic relations.

How can you act ethically in a publication system that attempts to regulate research activity in a way that you might find, in many respects, to be unethical? In this article, we address this question by drawing on the Aristotelian perspective of practical wisdom. Drawing on thirty semi-structured interviews with academics working in French business schools, we outline different means through which they act ‘wisely’ by deliberating and focusing on what is within their power and in line with their best (...) judgment. In particular, we show how some of them succeed in performing virtuous actions both within the publication system and beyond. (shrink)

The theory of embodiment is used in providing an account of the identity of acts and in providing solutions to various puzzles concerning acts.

Modal Meinongianism is a form of Meinongianism whose main supporters are Graham Priest and Francesco Berto. The main idea of modal Meinongianism is to restrict the logical deviance of Meinongian non-existent objects to impossible worlds and thus prevent it from “contaminating” the actual world: the round square is round and not round, but not in the actual world, only in an impossible world. In the actual world, supposedly, no contradiction is true. I will show that Priest’s semantics, as originally formulated (...) in Towards Non-being, tell us something different. According to certain models, there are true contradictions in the actual world. Berto and Priest have noticed this unexpected consequence and have suggested a solution, but I will show that their solution is highly questionable. In the last section of this paper, I will introduce a new and simpler version of modal Meinongianism that avoids the problem. (shrink)

Je montrerai en premier lieu comment et pourquoi la sémantique formelle peut être employée comme un outil pour déterminer l’engagement ontologique d’une théorie : je soutiendrai d’une part que la sémantique doit être prise au sérieux comme apte à décrire la vérifaction des formules du langage; d’autre part, que les engagements ontologiques d’une théorie sont déterminés par ses vérifacteurs. De là, j’exposerai une méthode générale permettant, étant donné un certain type d’ontologie, de construire une sémantique dont les engagements ontologiques sont (...) en accord avec celle-ci. Pour cela, je définirai la notion de cadre ontologique : il s’agit d’une structure telle que toute sémantique cons-truite à partir de cette structure aura un certain engagement ontologique déterminé à l’avance. J’exposerai quatre cadres représentant deux types de nominalisme et deux types de réalisme, et j’esquisserai à partir de ces cadres quatre sémantiques pour les langages du premier ordre. (shrink)

Starting with the hypothesis that analogical reasoning consists of a search of semantic space, we used eye-tracking to study the time course of information integration in adults in various formats of analogies. The two main questions we asked were whether adults would follow the same search strategies for different types of analogical problems and levels of complexity and how they would adapt their search to the difficulty of the task. We compared these results to predictions from the literature. Machine learning (...) techniques, in particular support vector machines (SVMs), processed the data to find out which sets of transitions best predicted the output of a trial (error or correct) or the type of analogy (simple or complex). Results revealed common search patterns, but with local adaptations to the specifics of each type of problem, both in terms of looking-time durations and the number and types of saccades. In general, participants organized their search around source-domain relations that they generalized to the target domain. However, somewhat surprisingly, over the course of the entire trial, their search included, not only semantically related distractors, but also unrelated distractors, depending on the difficulty of the trial. An SVM analysis revealed which types of transitions are able to discriminate between analogy tasks. We discuss these results in light of existing models of analogical reasoning. (shrink)

In the past 20 years, experimental philosophers have investigated folk intuitions about free will and moral responsibility, and their compatibility with determinism. To determine whether laypeople are “natural compatibilists” or “natural incompatibilists”, they have used vignettes describing agents living in deterministic universes. However, later research has suggested that participants’ answers to these studies are plagued with comprehension errors: either people fail to really accept that these universes are deterministic, or they confuse determinism with something else. This had led certain experimenters (...) to conclude that maybe folk intuitions about the compatibility of free will with determinism could not be empirically investigated. Here, we propose that we should refrain from embracing this pessimistic conclusion, as scenarios involving time loops might allow experiments to bypass most of these methodological issues. Indeed, scenarios involving time loops belong both to the philosophical literature on free will and to popular culture. As such, they might constitute a bridge between the two worlds. We present the results of five studies using time loops to investigate people’s intuitions about determinism, free will and moral responsibility. The results of these studies allow us to reach two conclusions. The first is that, when people are introduced to determinism through time loops, they do seem to understand what determinism entails. The second is that, at least in the context of time loops, people do not seem to consider determinism to be incompatible with free will and moral responsibility. (shrink)

Approche multipolaire de la pensée cartésienne, cet ouvrage aborde tout autant la métaphysique que la morale ou la science de ce dernier, et rend compte de son inépuisable richesse et de sa fécondité contemporaine.

Souvent ramenée aux écrits de Kant et Baumgarten, la question esthétique a rarement été abordée dans l’oeuvre de Descartes, ce que se propose pourtant d’examiner le présent ouvrage. Interrogeant le rapport de l’esprit à la sensibilité, mais aussi au plaisir (delectatio), il cherche à déterminer aussi bien la présence de conditions de possibilité d’une esthétique au sein des écrits cartésiens que la singularité de celle-ci. Confrontant les textes de Descartes avec ceux de Poussin et de Le Brun, ce livre rencontre (...) les débats classiques autour de la détermination objective du beau et conclut au refus cartésien d’établir une norme universelle de la beauté comme si cette dernière demeurait étrangère à toute approche rationnelle. Pour autant, l’ouvrage conclut sur l’étude d’une passion singulière, celle de l’admiration, par laquelle se révèle la possibilité d’une approche du beau qui fut à la fois universelle et rationnelle. Ce sont donc bien deux façons non concurrentes d’envisager la question du beau que cet ouvrage se propose de mettre à jour dans l’ensemble des écrits cartésiens. (shrink)

La mise en doute du monde sensible et intellectuel n’est-elle qu’une méthode? Ne s’agit-il pas plutôt d’une expérience fondamentale, offrant au sujet l’intuition de l’inconsistance de tout ce qui l’entoure? Mais cette précarité n’est peut-être que relative car Dieu et mon être s’imposent à moi comme une réalité incontestable. C’est le sens du discours cartésien qui, à travers une lecture subtile de l’œuvre et de ses commentateurs, est ici interrogé dans sa globalité. Interrogation fouillée qui met en lumière l’inspiration néo-platonicienne (...) de Descartes et les relations ambivalentes qui l’unissent aux penseurs de la Renaissance, loin des réductions heidegériennes. Une philosophie profondément humaniste qui continue d’irriguer notre modernité. (shrink)

Nicolas de Cues, Kant et Cassirer forment un triptyque philosophique au sein duquel l’auteur de la Philosophie des formes symboliques a pu révéler un chiasme fort éclairant : Kant ne saurait être lu sans que ne soit prêté attention au coup d’envoi cusanien, mais Nicolas de Cues ne saurait être compris sans le prisme des lunettes kantiennes grâce auquel la théorie de la connaissance servirait de guide pour la compréhension des textes de Nicolas. Il s’agit donc, dans la présente contribution, (...) d’interroger ce qu’il peut y avoir de kantien chez le Cusain, et de cusanien chez Kant, en prenant comme fil directeur le problème de la relation sujet-objet et la question de la chose en soi.

In recent previous work, the authors proposed a new approach extending the framework of statistical mechanics to reparametrization-invariant systems with no additional gauges. In this paper, the approach is generalized to systems defined by more than one Hamiltonian constraint. We show how well-known features as the Ehrenfest–Tolman effect and the Jüttner distribution for the relativistic gas can be consistently recovered from a covariant approach in the multi-fingered framework. Eventually, the crucial role played by the interaction in the definition of a (...) global notion of equilibrium is discussed. (shrink)
