Le volume "Images de Platon et lectures de ses oeuvres" rassemble vingt et une contributions consacrees a diverses relectures qui ont ete faites de l'oeuvre ecrite de Platon entre le IIIe siecle (Diogene Laerce, Plotin) et le XXe sievle (K. Popper). Dans l'introduction, Ada Neschke met en lumiere le cheminement de ces relectures et souligne le fait que les lectures de Platon sont constamment alimentees par des preoccupations propres a ses lecteurs. Dans un premier temps, l'oeuvre de Platon est integree (...) dans une optique essentiellement theologique; apres l'avenement du kantisme, elle s'inscrit dans un cadre de pensee qui se veut critique et philosophique, c'est-a-dire emancipe de l'ancienne metaphysique. Ainsi, l'oeuvre de Platon represente, d'une part, pour les penseurs chretiens une source d'inspiration concernant les sujets les plus divers: la theologie chretienne (Clement d'Alexandrie, Ficin, les Platoniciens de Cambridge), la mytho-theologie neo-platonicienne (Plethon), l'iconographie de la trinite (Francisco di Hollanda), la politique catholique et le calviniste (Jean Bodin, Jean de Serres), le scepticisme face aux debats theologiques (Montaigne). D'autre part, Platon a la valeur d'une autorite pour les penseurs postkantiens, que ce soit pour construire une philosophie de la nature (Schelling), une ethique (Hegel), une epistemologie (les neo-kantiens Cohen et Natorp) ou encore une ontologie (Heidegger). Enfin, Platon sert de reference dans les debats politiques modernes et contemporains, en particulier dans les discussions sur le liberalisme (J. St. Mill) et le totalitarisme (Popper et ses successeurs). De l'antiquite jusqu'a nos jours, Platon reste donc un auteur qui interpelle son lecteur et lui lance meme souvent un defi. (shrink)

ArgumentThe sphygmograph as designed and tested by Jules-Étienne Marey – an apparatus destined to write pulse tracings on paper – revolutionized medical diagnostics in the early 1860s. Since the accuracy with which this device registered and objectified the pulse was controversial from the outset, the young scholar Ernst Mach decided to thoroughly examine Marey's sphygmograph. The investigation led to the invention of an alternative, truly Machian, sphygmograph. Mach's sphygmograph had originated in the regime of theoretical and applied physics, whereas (...) the instrument invented by Marey had been rooted in the regime of experimental physiology. This one type of instrument thus serves as the focal object of a comparative study of two antagonistic epistemological approaches to sphygmography. (shrink)

Il faut attendre la fin du deuxième siècle pour voir Irénée faire le lien entre la fonction de « diacre » et le récit d’Actes 6 rapportant la création du groupe de Sept hellénistes. Pour le comprendre, on étudie la liaison entre le nombre Sept, la notion de diakonia, la fonction de glorification et surtout l’idée d’imitation par l’univers visible de l’univers invisible. Ces questions étaient au centre du débat entre Marc le Mage et Irénée. Elles se retrouvent dans les (...) spéculations de Clément d’Alexandrie autour du chandelier à 7 branches et des 7 « protoctistes » qui assurent la diaconie au ciel. Les structures ecclésiales sont ainsi conçues comme l’image des réalités célestes préexistantes. Le récit du martyre d’Étienne en Ac 6 contenait déjà quelques jalons qui ont permis à Irénée d’établir ce lien : si Étienne peut être dit « premier diacre » par Irénée, c’est parce que sa confession parfaite lui donne de voir s’ouvrir les cieux en contemplant la Gloire de Dieu.

. Computational chemistry grew in a new era of “desktop modeling,” which coincided with a growing demand for modeling software, especially from the pharmaceutical industry. Parameterization of models in computational chemistry is an arduous enterprise, and we argue that this activity leads, in this specific context, to tensions among scientists regarding the epistemic opacity transparency of parameterized methods and the software implementing them. We relate one flame war from the Computational Chemistry mailing List in order to assess in detail the (...) relationships between modeling methods, parameterization, software and the various forms of their enclosure or disclosure. Our claim is that parameterization issues are an important and often neglected source of epistemic opacity and that this opacity is entangled in methods and software alike. Models and software must be addressed together to understand the epistemological tensions at stake. (shrink)

«Etienne Gilson laissait à sa mort, en septembre 1978, le manuscrit d'un ouvrage largement inédit dont il avait achevé la préparation dix ans plus tôt, à en croire l'indication marginale "janvier 1968" qui figure sur la table des matières, complète et paginée. Ce volume posthume qu'Etienne Gilson avait intitulé malicieusement Constantes philosophiques de l'être comporte huit chapitres, inédits pour moitié, tandis que les autres reprennent sous une forme parfois assez différente et généralement plus développée la matière d'essais publiés séparément de (...) 1952 à 1967. La composition des textes ainsi rassemblés s'échelonne donc sur une quinzaine d'années sans qu'on puisse toujours dater avec précision la rédaction des quatre chapitres jusqu'à présent inédits. Ce qui est sûr en tout cas, c'est que, comme l'auteur le souligne lui-même dans sa Préface, tous ont été conçus dans la perspective d'un recueil d'ensemble, qui s'est constitué progressivement et comme de lui-même. Le présent ouvrage, beaucoup plus doctrinal qu'historique, se situe par ailleurs dans le prolongement direct des réflexions que le grand historien avait d'abord développées dans l'Etre et l'Essence. L'auteur y poursuit en particulier, à la faveur d'une mise en perspective de l'ensemble de la tradition philosophique occidentale, un débat déjà engagé dans les appendices de la seconde édition de l'Etre et l'Essence, en 1962 ; débat qui porte sur ce que Gilson nomme ici "la nouvelle philosophie de l'être". S'interrogeant en philosophe "sur les données de l'histoire", l'historien demande à présent : "qu'y a-t-il de nouveau dans les aventures de l'être?", la nouveauté tenant pour l'essentiel au "cas Heidegger". Par où l'historien de la pensée médiévale n'ajoute pas simplement une pièce nouvelle au dossier déjà volumineux de l'interprétation thomiste de la Seinsfrage, mais contribue, à sa façon, à la position de la question de la structure ontothéologique de la métaphysique.» -- Page 4 de la couverture.

Computational reproducibility possesses its own dynamics and narratives of crisis. Alongside the difficulties of computing as an ubiquitous yet complex scientific activity, computational reproducibility suffers from a naive expectancy of total reproducibility and a moral imperative to embrace the principles of free software as a non-negotiable epistemic virtue. We argue that the epistemic issues at stake in actual practices of computational reproducibility are best unveiled by focusing on software as a pivotal concept, one that is surprisingly often overlooked in accounts (...) of reproducibility issues. Software is not only about designing and coding but also about maintaining, supporting, distributing, licensing, and governance; it is not only about developers but also about users. We focus on openness debates among computational chemists involved in molecular modeling software packages as empirical grounding for our argument. We then identify and analyse four epistemic characteristics as key to the role of software in computational reproducibility. (shrink)

In a previous article on cosmological arguments, I have put forward a few examples of complete infinite and circular explanations, and argued that complete non-wellfounded explanations such as these might explain the present state of the world better than their well-founded theistic counterparts (Billon, 2021). Although my aim was broader, the examples I gave there implied merely causal explanations. In this article, I would like to do three things: • Specify some general informative conditions for complete and incomplete non-wellfounded causal (...) explanations that can be used to assess candidate explanations and to generate new examples of complete non-wellfounded explanations. • Show that these conditions, which concern chains of causal explanations, easily generalize to chains of metaphysical, grounding explanations and even to chains involving other “determination relations” such as supervenience. • Apply these general conditions to the recent debates against the existence of nonwellfounded chains of grounds and show, with a couple of precise examples, that the latter can be complete, and that just like in the case of causal explanations, non-wellfoundedness can in fact be an aset rather than a liability.

Using emotional film clips is one of the most popular and effective methods of emotion elicitation. The main goal of the present study was to develop and test the effectiveness of a new and comprehensive set of emotional film excerpts. Fifty film experts were asked to remember specific film scenes that elicited fear, anger, sadness, disgust, amusement, tenderness, as well as emotionally neutral scenes. For each emotion, the 10 most frequently mentioned scenes were selected and cut into film clips. Next, (...) 364 participants viewed the film clips in individual laboratory sessions and rated each film on multiple dimensions. Results showed that the film clips were effective with regard to several criteria such as emotional discreteness, arousal, positive and negative affect. Finally, ranking scores were computed for 24 classification criteria: Subjective arousal, positive and negative affect (derived from the PANAS; Watson & Tellegen, 1988), a positive and a negative affect scores derived from the Differential Emotions Scale (DES; Izard et al., 1974), six emotional discreteness scores (for anger, disgust, sadness, fear, amusement and tenderness), and 15 “mixed feelings” scores assessing the effectiveness of each film excerpt to produce blends of specific emotions. In addition, a number of emotionally neutral film clips were also validated. The database and editing instructions to construct the film clips have been made freely available in a website. (shrink)

This is a commentary on Andrea Lavazza and Murilo Vilaça's article "Human Extinction and AI: What We Can Learn from the Ultimate Threat" (Lavazza & Vilaça, 2024). I discuss the potential concern that their proposal to create artificial successors to "insure" against the tragedy of human extinction might mean being too quick to accept that catastrophic prospect as inevitable, rather than single-mindedly focusing on avoiding it. I also consider the question of the value that we might reasonably assign to such (...) a future of artificial successors under the assumption that they do not enjoy phenomenal consciousness.

Patients suffering from the Cotard syndrome can deny being alive, having guts, thinking or even existing. They can also complain that the world or time have ceased to exist. In this article, I argue that even though the leading neurocognitive accounts have difficulties meeting that task, we should, and we can, make sense of these bizarre delusions. To that effect, I draw on the close connection between the Cotard syndrome and a more common condition known as depersonalisation. Even though they (...) are not delusional, depersonalised patients seem to have experiences that are quite similar to those of Cotard patients. I argue that these experiences are essentially characterised by a lack of subjective character and of two other structural features of experience, which I call ‘the present character’ and ‘the actual character’. Cotard's nihilistic delusions simply consist in taking these anomalous experiences at face value. (shrink)

This paper focuses on one particular case that connects climate justice and climate economics. Its contribution is twofold. First, it aims at providing a sound normative foundation for carbon pricing mechanisms around the notions of a ‘right to energy’, the ‘duty not-to-harm’ and an argument for ‘restricted compensation’. Second, it identifies the normative elements from theories of climate justice that should guide the design of market-based instruments for climate change mitigation. This will cast light on the particular moral relevance of (...) the act of internalizing a negative externality and of the funds generated by putting a price on carbon. (shrink)

Western European liberal democracies have recently enacted laws that prohibit the diffusion of fake news on social media. Yet, many consider that such laws are incompatible with freedom of expression. In this paper, I argue that democratic governments have strong pro tanto reasons to prohibit fake news, and that doing so is compatible with free speech. First, I show that fake news disrupts a mutually beneficial form of epistemic dependence in which members of the public are engaged with journalists. Second, (...) I contend that laws against fake news enhance rather than thwart personal autonomy. If these suggestions are plausible, then the same considerations about truth and autonomy that underpin the value of free speech give us reasons to prohibit fake news. (shrink)

Patients suffering from depersonalization complain of feeling detached from their body, their mental states, and actions or even from themselves. In this chapter, I argue that depersonalization consists in the lack of a phenomenal feature that marks my experiences as mine, which is usually called “mineness,” and that the study of depersonalization constitutes a neglected yet incomparable probe to assess empirically the scope, role, and even the nature of mineness. Here is how I will proceed. After describing depersonalization (§2) and (...) arguing that it involves a lack of mineness (§3) I will confront a series of objections (§4). I will then spell out what depersonalization can teach us about the scope of mineness (§5), about its role and psychological function (§6) and even about its nature (§7). (shrink)

One objection to enhancement technologies is that they might lead us to live inauthentic lives. Memory modification technologies (MMTs) raise this worry in a particularly acute manner. In this paper I describe four scenarios where the use of MMTs might be said to lead to an inauthentic life. I then undertake to justify that judgment. I review the main existing accounts of authenticity, and present my own version of what I call a “true self” account (intended as a complement, rather (...) than a substitute, to existing accounts). I briefly describe current and prospective MMTs, distinguishing between memory enhancement and memory editing . Moving then to an assessment of the initial scenarios in the light of the accounts previously described, I argue that memory enhancement does not, by its very nature, raise serious concerns about authenticity. The main threat to authenticity posed by MMTs comes, I suggest, from memory editing. Rejecting as inadequate the worries about identity raised by the President’s Council on Bioethics in Beyond Therapy , I argue instead that memory editing can cause us to live an inauthentic life in two main ways: first, by threatening its truthfulness, and secondly, by interfering with our disposition to respond in certain ways to some past events, when we have reasons to respond in such ways. This consideration allows us to justify the charge of inauthenticity in cases where existing accounts fail. It also gives us a significant moral reason not to use MMTs in ways that would lead to such an outcome. (shrink)

Natural modalities are often analysed from an abstract point of view where they are associated with putative laws of nature. However, the way possibilities are represented in physics is more complex. Lagrangian mechanics, for instance, involves two different layers of modalities: kinematical and dynamical possibilities. This paper examines the status of these two layers, both in the classical and quantum case. The quantum case is particularly problematic: we identify four possible interpretive options. The upshot is that a close inspection of (...) the way possibilities are represented in physics could lead to new ways of thinking about natural modalities. (shrink)

Consider an infinite series whose items are each explained by their immediate successor. Does such an infinite explanation explain the whole series or does it leave something to be explained? Hume arguably claimed that it does fully explain the whole series. Leibniz, however, designed a very telling objection against this claim, an objection involving an infinite series of book copies. In this paper, I argue that the Humean claim can, in certain cases, be saved from the Leibnizian “infinite book copies” (...) objection, and that this provides an interesting way to defuse some cosmological arguments for the existence of God and to give a non-theistic but complete explanation of the Universe. In the course of my argumentation, I also show that circular explanations can be “self-explanatory” as well: explaining two items by each other can explain the couple of items tout court. (shrink)

This paper examines the social and organizational innovation processes undertaken by small-scale producers engaged in short food supply chains in the North Swedish region of Västerbotten. The study uses the notion of proximity to empirically analyse and conceptually explore these phenomena. The paper illustrates the ‘new associationalism’ mobilized by producers in order to promote knowledge exchange and learning and highlights the role of translocal practices in sustaining this transition. The study found that open and trusted interactions with consumers are central (...) to the development of ‘quasi-organic’ practices, and that producers belong to numerous motley associations of food professionals facilitating the creation of collective meanings about near-produced quality food. The paper contributes to the rapprochement between agri-food studies and human geography to understand the formation of local food systems from an evolutionary and relational perspective. (shrink)

According to what we will call subjectivity theories of consciousness, there is a constitutive connection between phenomenal consciousness and subjectivity: there is something it is like for a subject to have mental state M only if M is characterized by a certain mine-ness or for-me-ness. Such theories appear to face certain psychopathological counterexamples: patients appear to report conscious experiences that lack this subjective element. A subsidiary goal of this chapter is to articulate with greater precision both subjectivity theories and the (...) psychopathological challenge they face. The chapter’s central goal is to present two new approaches to defending subjectivity theories in the face of this challenge. What distinguishes these two approaches is that they go to great lengths to interpret patients’ reports at face value – greater length, at any rate, than more widespread approaches in the extant literature.

Several advocates of the lively field of “metaphysics of science” have recently argued that a naturalistic metaphysics should be based solely on current science, and that it should replace more traditional, intuition-based, forms of metaphysics. The aim of the present paper is to assess that claim by examining the relations between metaphysics of science and general metaphysics. We show that the current metaphysical battlefield is richer and more complex than a simple dichotomy between “metaphysics of science” and “traditional metaphysics”, and (...) that it should instead be understood as a three dimensional “box”, with one axis distinguishing “descriptive metaphysics” from “revisionary metaphysics”, a second axis distinguishing a priori from a posteriori metaphysics, and a third axis distinguishing “commonsense metaphysics”, “traditional metaphysics” and “metaphysics of science”. We use this three-dimensional figure to shed light on the project of current metaphysics of science, and to demonstrate that, in many instances, the target of that project is not defined with enough precision and clarity.

If citizens are to make enlightened collective decisions, they need to rely on true factual beliefs, but misinformation impairs their ability to do so. Although some cases of misinformation are deliberate and amount to propaganda, cases of inadvertent misinformation are just as problematic in affecting the beliefs and behavior of democratic citizens. A review of empirical evidence suggests that this is a serious problem that cannot entirely be corrected by means of deliberation.

Gilbert and colleagues are to be commended for drawing our attention to the need for a sounder empirical basis, and for more careful reasoning, in the context of the neuroethics debate on Deep Brain Stimulation (DBS) and its potential impact on the dimensions of personality, identity, agency, authenticity, autonomy and self (PIAAAS). While acknowledging this, this extended commentary critically examines their claim that the real-world relevance of the conclusions drawn in the neuroethics literature is threatened by the fact that the (...) concepts at the center of the discussion have “weak empirical grounding”. First, I show that while some possible understandings of multifaceted concepts like identity, authenticity and autonomy may indeed be unsuitable for a purely empirical inquiry, this is not the case of all of them. Secondly, I call into question the authors’ apparent suggestion that reliance on constructs involving an irreducibly normative dimension makes for a suboptimal state of affairs, and that they should ideally be replaced with substitutes taken from the language of neuroscience or social science in order to ensure an adequate empirical grounding for the debate. Such a suggestion, I argue, commits the authors to a controversial reductionist view in metaethics that the valid empirical concerns they raise in the rest of their article do not presuppose, and which could potentially us lead to lose sight of important ethical considerations.

Authenticity has recently emerged as an important issue in discussions of mental disorder. We show, on the basis of personal accounts and empirical studies, that many people with psychological disorders are preoccupied with questions of authenticity. Most of the data considered in this paper are from studies of people with bipolar disorder and anorexia nervosa. We distinguish the various ways in which these people view the relationship between the disorder and their sense of their authentic self. We discuss the principal (...) modern ac-counts of authenticity within the analytic philosophical tradition. We argue that accounts based on autonomous, or wholehearted, endorsement of personal characteris-tics fail to provide an adequate analysis of authenticity in the context of mental disorder. Significant elements of true self accounts of authenticity are required. The concept of authenticity is a basic one that can be of particular value, in the context of self-development, to people with mental disorder and to others experiencing substantial inner conflict.

Vous menez depuis plusieurs années des enquêtes sur le personnel politique en France, avec l’ambition de reconsidérer la notion de « professionnel » de la politique et par extension les ressorts d’une « professionnalisation » de la vie politique en France.

Descartes was certain that he was thinking and he was accordingly certain that he existed. Like Descartes, we seem to be more certain of our thoughts and our existence than of anything else. What is less clear is the reason why we are thus certain. Philosophers throughout history have provided different interpretations of the cogito, disagreeing both on the kind of thoughts it characterizes and on the reasons for its cogency. According to what we may call the empiricist interpretation of (...) the cogito, I can only claim to be certain of having experiences, and this certainty, as well as that of my own existence, stems from their phenomenal and subjective character. According to rationalist interpretations, on the other hand, I am certain of having some self-reflexive propositional attitudes, and this certainty derives from their rational features. Psychiatric patients suffering from acute forms of depersonalization or of the Cotard syndrome often doubt that they think and exist, and might even believe that they don't. I argue that their study allows us to favor the empiricist interpretation of the cogito. (shrink)

In their target article, Kammerer and Frankish (K&F) wonder what forms introspection could take in non-human animals, enhanced humans, artificial intelligences, and aliens. In this short note, I focus on disordered or neurodiverse minds. More specifically, I assess a claim that has often been made more or less implicitly to the effect that, in virtue of their conditions, people with schizophrenia or depersonalization disorder have superior introspective abilities that allow them to discern some important but normally hidden characteristics of our (...) experiences — call this the superintrospectionitis thesis. In the course of my argumentation, I introduce distinctions and questions concerning the nature of the architecture and the function of introspection that might enrich K&F's framework. (shrink)

Cet article propose une analyse croisée du discours médical sur la masturbation et sur la lecture en France au XVIIIe siècle. Son but est d’interroger la construction de la définition « naturalisante » des qualités attribuées à l’un et l’autre sexe.

Comment un médecin neutralise-t-il le danger, pour une femme, de lire un (...) traité sur un sujet tel que la masturbation? Comment le discours sur la lecture et la masturbation fonctionne-t-il comme système discriminant entre les sexes? (shrink)

Depersonalization is a pathological condition consisting in a deep modification of the way things appear to a subject, leading him to feel estranged from his body, his actions, his thoughts, his mind and even from himself. In this article, I argue that the study of depersonalization raises three challenges for recent theories of the sense of bodily ownership. These challenges—which I call the centrality challenge, the dissociation challenge and the grounding challenge— thwart most of these theories and suggest that the (...) sense of bodily ownership hinges on a phenomenal mark of mineness that can not be accounted for in terms of our sensory, interoceptive, agentive, cognitive or affective dispositions and that is psychologically primitive. In short: that mineness is first. (shrink)

Basic self-awareness is the kind of self-awareness reflected in our standard use of the first-person. Patients suffering from severe forms of depersonalization often feel reluctant to use the first-person and can even, in delusional cases, avoid it altogether, systematically referring to themselves in the third-person. Even though it has been neglected since then, depersonalization has been extensively studied, more than a century ago, and used as probe for understanding the nature and the causal mechanisms of basic self-awareness. In this paper, (...) I argue that depersonalized patients indeed have an impaired basic self-awareness, and that their study allows us both to favor one specific theory of basic self-awareness and to understand what is wrong with its rivals. According to the favored theory, which I call Cartesian, we are basically self-aware in virtue of being acquainted with ourselves through introspection. (shrink)

In this paper, we put forward a new account of emergence called “transformational emergence”. Such an account captures a variety of emergence that can be considered as being diachronic and weakly ontological. The fact that transformational emergence actually constitutes a genuine form of emergence is motivated. Besides, the account is free of traditional problems surrounding more usual, synchronic versions of emergence, and it can find a strong empirical support in a specific physical phenomenon, the fractional quantum Hall effect, which has (...) long been touted as a paradigmatic case of emergence.

Many philosophers have adopted epistemic expressivism in recent years. The core commitment of epistemic expressivism is that epistemic claims express conative states. This paper assesses the plausibility of this commitment. First, we raise a new type of problem for epistemic expressivism, the epistemic motivation problem. The problem arises because epistemic expressivists must provide an account of the motivational force of epistemic judgment (the mental state expressed by an epistemic claim), yet various features of our mental economy seem to show that (...) they can’t do so. Second, we develop what we take to be the most promising response to that problem for expressivists. We end by noting that this response faces an important challenge pertaining to the psychology of epistemic criticism and praise. (shrink)
