Dans le sillage de Chris Marker ou de Grégory Chatonsky, de plus en plus d’artistes contemporains pratiquent la réappropriation, le détournement, l’usage critique de l’intelligence artificielle. Grand connaisseur des arts numériques, Fabien Zocco est l’un d’entre eux. Il est l’auteur, avec le réalisateur Gwendal Sartre, d’ Attack The Sun, film dont des dialogues ont été générés par une IA au cours même du tournage qui suit la dérive d’un youtuber californien paraissant sombrer dans une folie de tuerie. L’enjeu : (...) éprouver « de l’intérieur » des outils contemporains comme l’IA pour « escompter ensuite analyser et déconstruire leurs effets ». (shrink)

According to some recent empirical studies revealing that creativity is linked to sensorimotor components, the current research was aimed at evaluating whether sensory afferences could modulate originality in drawing of children and adolescents. Sixty-nine children from 1st, 3rd, 6th, and 8th grades were required to produce a man who exists and a man who doesn’t exist with fingers or stylus on a tablet and with a pen on paper. Drawings were assessed with an originality scale comparing original drawings to unoriginal (...) ones. Since, in comparison to drawings made on paper with a pen, drawing with fingers enhances proprioceptive information, this condition was expected, according to cognitive load theory, to favor originality in drawing by reducing cognitive resources devoted to motor control of the graphic gesture. On the contrary, since the use of a stylus involves a proprioceptive loss of information, which enhances intrinsic load by increasing cognitive resources devoted to motor control, it was expected that drawing with a stylus on the tablet would lead to the least original drawings. Results only partially confirmed these hypotheses. While the use of fingers on the tablet led to the highest original scores, using a stylus on the tablet did not impair originality in drawing of children and adolescents. On the opposite, the use of a stylus led 3rd–8th graders to perform better than with pen on paper. This modulation of the tool on originality does not confirm the hypotheses formulated in accordance with the cognitive load framework. However, it could be explained according to an embodied perspective of creativity considering the creative process as relying on a sensorimotor prediction process in which sensory afferences are central to generating and evaluate creative ideas. This research opens new avenues on creativity and proposes to consider the development of predictive motor control as a significant part of creativity development. (shrink)

On analyse ici la structure et la dynamique d’un champ économique : le champ des opérations de LBO en France dans les années 2000. À partir de données relationnelles et de documents couvrant la période 2000-2010, nous tentons d’en expliquer l’explosion et l’implosion en identifiant trois mécanismes opérant à des échelles de temps distinctes et superposées : l’hégémonie financière, la coopération entre concurrents et la réaction aux crises. L’article illustre une manière d’utiliser l’analyse de réseaux sociaux afin de formaliser un (...) champ organisationnel et d’articuler structure et processus dans des ordres sociaux de niveau intermédiaire.

Contrairement à ce qu’ont affirmé un certain nombre d’historiens et d’historiennes, les femmes ont une place dans l’espace social vénitien aux xve et xvie siècles. Elles appartiennent à l’espace domestique, mais elles sont aussi présentes à l’extérieur, dans les rues et sur les places. Cette étude s’appuie sur des sources picturales pour discuter la présence féminine dans l’espace extérieur et l’espace domestique vénitiens. Peintes par des artistes masculins, elles sont représentées selon des codes bien précis dans l’espace extérieur, souvent à (...) l’image de la Vierge Marie ou d’autres figures saintes. Mais nous verrons également que l’incursion des peintres au sein des case venetiane, qui entraîne une manière plus réaliste de représenter la figure féminine et leur offre une plus grande visibilité, leur permet de gagner une certaine liberté de mouvement, parfois au détriment de leur réputation.

Valuing conservation and biodiversity outcomes in economic analysis is difficult, as it is in health economics. Because health economics has previously had to respond to the many challenges currently faced by conservation economics, health economists have developed very successful tools for responding to these challenges which conservation economists can draw upon. What is surprising is that despite rhetorical support for the use of these economic analysis tools in conservation valuations, in practice, these economic tools are used far less frequently in (...) conservation and biodiversity decision then they are in health decisions. Drawing on a simple database search and an analysis of universities that lead in both economics and environmental studies, this paper considers why conservation economists stick with philosophically and pragmatically difficult economic tools when they have other options, and argues that part of the reasons is the way conservation economics is framed and conceptualised.

The concept of continuous creation is now widely used in the context of reflections on the dialogue between science and religion. The first part of this research work seeks to understand its meaning through a twofold elaboration: (1) the historical setting of the three philosophical trends in which this concept was developed: scholastic (conservation), Cartesian (conservation through repetition of the creative act at each instant), and dynamic (interpreting the emergence of radical and contingent novelty in nature as a sign of (...) the continuity of creation); (2) a philosophical and theological critique of the concept of continuous creation regarding the question of the relationship between change and creation, in the light of its highly polymorphous contemporary use, and, in opposition, its absence within the Catholic Magisterium. This work opens the field a further step toward reflection on a renewed concept of continuous creation. (shrink)

A logical theory of oppositions deals with the relation between propositions and their truth values. On the basis of a formal semantics that proceeds by means of questions-answers, three theses are claimed in the following: (1) the concept of opposition usually refers to incompatibility, but our logical analysis focusses upon a broader relation of difference; (2) more generally, opposition has to do with negativity; our semantics accounts for it through opposite-forming operators; (3) subalternation is a particular case of non-contradiction expressing (...) an “opposition of an opposition”; it is not a proper opposition, accordingly, but its very meaning depends upon the latter. There is not only one but rather a number of expressions for negativity and the paper presents a detailed analysis of these "floating" expressions in a twofold sense of the word: floating quantification is closely related to the logical operations of sentential negation and denial; to what extent natural languages do not clearly express the meaning of a negative thought will be exemplified. L'objectif du texte qui suit est double : non seulement proposer une analyse logique du concept d'opposition, susceptible d'apporter de la précision à cette notion tout aussi vague que courante ; mais aussi, proposer une explication des différentes façons dont la négation se manifeste dans les langues naturelles, en particulier dans notre modèle local de la langue française. Tandis que la communauté des linguistes propose couramment une distinction entre une négation logique et une négation linguistique, l'article qui suit a la prétention d'une explication unifiée de la négation, c'est-à-dire un cadre théorique commun dans lequel ces deux aspects de l'opérateur de négation apparaissent comme des cas particuliers aux significations distinctes. Il n'y aurait donc pas une négation logique, d'un côté, et une négation linguistique ou "métalinguistique", de l'autre. Une approche structurelle des expressions négatives devrait apporter un éclairage sur ce point, par le biais d'une analyse algébrique de la signification en termes de questions-réponses. Mais revenons pour commencer sur l'origine philosophique du concept d'opposition, avant d'en exposer les propriétés logiques par la suite et les expressions linguistiques pour conclure. (shrink)

This article develops a historico-critical analysis of uncertainty and accuracy in measurement through a case-study of the adjustment of the fundamental physical constants, in order to investigate the sceptical “problem of unknowability” undermining realist accounts of measurement. Every scientific result must include a “measurement uncertainty”, but uncertainty cannot be be eval- uated against the unknown, and therefore cannot be taken as an assessment of “accuracy”, defined in the metrological vocabulary as the closeness to the truth. The way scientists use and (...) interpret uncertainty in the adjustment activity illustrates how they try to overcome this predicament. I iden- tify two operative roles of measurement uncertainty, in the comparison and in the combination of measurement results. This duality implies a tension between selection and combination when aggregating results, leading to a crucial question: should the evaluation of uncertainties favour safety over precision? I present contrasting answers and identify a specific account of physicists who implicitly try to conciliate realism with the problem of unknowability. I argue that this invites us to reconsider accuracy from a dynamical standpoint, as the gradual achievement of scientific progress through error correction. Finally, I present two interpretations of measurement uncertainty, objective and epistemic, which I criticize and suggest improvements to. (shrink)

The aim of this chapter is to develop a semantics for Calculus CL. CL is a diagrammatic calculus based on a logic machine presented by Johann Christian Lange in 1714, which combines features of Euler-, Venn-type, tree diagrams, squares of oppositions etc. In this chapter, it is argued that a Boolean account of formal ontology in CL helps to deal with logical oppositions and inferences of extended syllogistics. The result is a combination of Lange’s diagrams with an algebraic semantics of (...) terms: Bit-CL, in which any ordered objects are identified by characteristic bitstrings. Then, a number of objections to Bit-CL are answered to, and the process of inference is explained in this new logical framework. (shrink)

Le philosophe Gerald A. Cohen est décédé le 5 août 2009. Sa contribution s’est d’abord articulée autour de la pensée de Marx. Elle émergea sur la scène intellectuelle en 1978 avec la parution de Karl Marx’s Theory of History : A Defence, qui impulsa la constitution du marxisme analytique. Par la suite, Cohen tendit à se détacher progressivement de la théorie de Marx. Il participa à la discussion sur le concept libertarien de propriété de soi en vue de l’associer à (...) une approche marxiste, avant d’intégrer pleinement le débat normatif autour des problématiques de justice sociale, autour de la Théorie de la justice de John Rawls. Fondée sur la philosophie kantienne, sa critique de la théorie de Rawls lui reproche de ne pas accorder suffisamment d’autonomie aux choix individuels. Le présent article discute la pertinence du voyage intellectuel de Jerry Cohen dans son rapport à l’œuvre de Marx. (shrink)

My aim in this book is to propose a comparativist, Buddhist-Neoplatonic interpretation of the idea of “logos” in the Prologue to the Gospel according to John. To do so, I proceed in three steps. I begin with Nāgārjuna’s doctrine of emptiness. Nāgārjuna thinks that that all things are empty because they depend on causes and conditions in a way that makes it impossible for them to genuinely exist. Nevertheless, they are not completely non-existent, for they possess the appearance of something (...) that exists. This corresponds, in turn, to Vasubandhu’s response to Nāgārjuna. Emptiness is not ultimate because there is the appearance of empty things. The place where this appearance unfolds is the mind, which, in an absolute sense, exists, but which, in the sense of external, objectifiable reality does not exist. Vasubandhu thus thinks of the mind as an entity that does not conform to the categories of ordinary existence. This, then, corresponds to what Meister Eckhart says about God. God is a Mind ("intellectus"). But due to his fundamental ontological role, God transcends ordinary existence and cannot be compared to any specific being. God is the mind of which Vasubandhu states that it is non-dual, transcendent knowledge. To conclude, I use this triadic constellation of Buddhist and Neoplatonic concepts to read John’s Prologue. The Prologue describes the generation of a foundational concept, “logos,” by a primordial, divine Mind. Since this Mind is, in a Buddhist sense, “empty,” the concept that it generates can be said to be absolute. It has no beginning and no cause. Against this background of Buddhist and Neoplatonic ideas, John’s Prologue can thus be interpreted as a narrative describing the foundation of reality as an intellectual process. (shrink)

Wittgenstein took the _Tractatus Logico-Philosophicus_ to be eventually invalidated by logical atomism. Our main thesis is that it can be revalidated, provided that we subtract the thesis 2.02 (“The object is simple.”) from it: atoms are not simple objects but, rather, bits of information the objects are made of. Starting from an introductory discussion about what is meant by a ‘logic of colors’, an explanatory framework is then proposed in the form of a partition semantics. The philosophical problem of Wittgenstein’s (...) color-statements is reformulated accordingly, thus overcoming the trouble with logical atomism. A Boolean treatment is advanced to solve the initial difficulty and leads to two final results: Wittgenstein’s logic of colors requires a mereological understanding of the relations between colors in order to make sense; the analysis of psychophysical concepts like colors casts some additional doubt about the analytic–synthetic distinction, to the point of treating relations between colors as analytic a posteriori judgments.

The logic of conditional is developed hereby in a series of papers, contributing to a historical and critical analysis of what the logical constant is expected to mean.

The renewal of the concept of continuous creation follows two steps: (1) an establishment of the concept of novelty in an exercise of philosophy of nature, as a means of interpreting the scientific discourse concerning the evolution of life; (2) starting out from philosophical and theological critiques and from the concept of novelty, this work proposes a reformulation of the concept of continuous creation in its dynamic perspective. If the universe of possibilities of creation proceeds from the Divine Word by (...) the will of the Father, as the first timeless ex nihilo creative moment, the Holy Spirit allows, in a second creative moment, the universe of possibilities to proceed continuously through a creative partnership in which all creatures are involved. Created novelty is the expression of a procession of one possibility among others, which has been selected by creatures during the evolutionary process, due to the interdependence of constitutive interactions and the propensities in which creatures are situated.

In this article the author tries to answer the difficult question of the roots of the welfare state. The study of the French example shows that if some roots are ideological, at the same time they are sociological, too. In the article the main streams of ideological roots are described and conclusion is drawn that nowadays sociological issues are very important. The popularity of the welfare state shows that dismantlement is impossible in the democratic States. Yet, its crisis due to (...) its cost in a globalized world asks the question of the balance point between the fight against assistantship and maintenance of the redistributive nature of the welfare state. The answer to that question still remains the key challenge for European politicians. (shrink)

Quelle relation la raison entretient-elle avec les atrocités des totalitarismes contemporains ou quelle compréhension de la raison permet ou impose le déferlement de ces totalitarismes et de leurs horreurs? Nous avons voulu brosser ici un tableau général des réinterprétations de la rationalité accomplies à partir de cette nouvelle situation historique. Notre intention n’est donc nullement de livrer une chronique de l’émigration des « intellectuels » fuyant le nazisme mais de montrer dans quelle mesure leur conception de la raison s’en est (...) trouvée changée et les modifications méthodologiques que cette émigration a entraîné dans leurs œuvres.

We argue that the diagram is the equivalent of the Kantian schema, i.e. the translation into time and space of a meaning, and therefore of a concept, which would otherwise be empty. Understood as a schematic structure materialized in a support, the diagram is the explicitation of the meaning of the concept understood as a guide to action. We show why the class of judgements made by diagrammatic intuition is equivalent to that of the "steps" - the expression is Peirce's (...) – used to produce a theorem. Such an analysis allows us to argue in favour of the thesis that the schematism at work in the organic production of form is fundamentally diagrammatic in nature, which is why we speak of a diagrammatic schematism of morphogenesis.

Les diagrammes appartiennent à une classe d’objets graphiques située à l’intersection de la théorie des médias, de la sémiotique visuelle et du design. Nous montrons que leur analyse révèle un mode de fonctionnement permettant de caractériser le diagrammatique comme un nouveau régime de rationalité dans l’histoire de l’écriture. Cette étude vise ainsi à identifier les spécificités de ce régime pour commencer à caractériser sa différence avec les régimes d’écritures alphabétique et numérique. Elle ouvre sur un programme de recherche initiant une (...) nouvelle approche médiatique qui s’inscrit dans le sillage de travaux réalisés en anthropologie historique des pratiques d’écriture.

Soumettre à l'analyse phénoménologique la relation d'altérité et découvrir au cœur de celle-ci la « signifiance » de la responsabilité, telle fut la tâche poursuivie et menée à terme par Emmanuel Lévinas (décédé le 25 décembre 1995). En s'inspirant de ses maîtres Husserl et Heidegger, et aussi en s'opposant à eux, Lévinas a mis en question l'ontologie, a proposé un « autre qu'être » de nature éthique, c'est-à-dire une responsabilité illimitée envers Autrui. Son œuvre apparaît comme une parole vocatrice et (...) pro-vocatrice, apte à secouer l'engourdissement de nos esprits par une dénonciation de l'individualisme et du souci de soi. Sa philosophie est la confrontation neuve et combien originale d'un « Je » souverain avec un « Autrui » à figure d'Étranger « de premier venu », non appropriable par la connaissance, côtoyé non plus dans l'indifférence d'un côte à côte, mais affronté dans la droiture d'un face-à-face. Le présent ouvrage paraît au moment où l'œuvre monumentale de Lévinas est désormais achevée. La première originalité de ce livre est de s'attaquer au noyau dur de la pensée de Lévinas, en abordant les thèmes d'altérité et de responsabilité. Sa seconde originalité réside dans son souci d'offrir une voie d'accès simplifiée pour aborder une œuvre qui ne livre pas facilement sa grande richesse. Le style est clair, le texte parfaitement structuré, le vocabulaire lévinassien et son évolution au fil de l'œuvre sont mis en relief. Les notions philosophiques trop spécialisées sont évitées afin de permettre à des lecteurs moins familiers avec la philosophie d'aborder sans découragement la pensée de Lévinas. (shrink)

Ce livre commence avec un problème de nomination de ce que l'on appelle économie et avec la disparition du terme chrématistique. Il pose l'hypothèse qu'il s'agit d'un problème métaphysique d'interprétation du réel et du monde. Le livre continue avec l'hypothèse étrange qui consiste à dire que la disparition du terme chrématistique est en lien avec la transformation substantielle et radicale du terme poièsis. Il pose alors la thèse qu'il y a une source fondamentale pour penser le problème de l'agir et (...) de l'opérativité et pour interpréter ce que l'on nomme une économie de l'œuvre. Enfin ce livre indique des manières de lire l'œuvre moderne et contemporaine en supposant qu'il y a eu, à cet endroit, un irrémédiable tournant : c'est ce que nous appelons critique de la poièsis. Ce livre pourra être lu de trois manières différentes et conjointes : comme un traité métaphysique de l'opérativité et de la disqualification des agir, comme un traité esthétique pour la lecture moderne du concept de poièsis (autrement dit de l'œuvre et de ses crises) et enfin comme un traité de philosophie politique en vue de faire face à ce qui tient de notre extrême et scandaleux contemporain.

A general theory of logical oppositions is proposed by abstracting these from the Aristotelian background of quantified sentences. Opposition is a relation that goes beyond incompatibility (not being true together), and a question-answer semantics is devised to investigate the features of oppositions and opposites within a functional calculus. Finally, several theoretical problems about its applicability are considered.

We present the Jaina theory of sevenfold predication as a 7-valued logic, in which every logical value consists in a 3-tuple of opinions. A question-answer semantics is used in order to give an intuitive characterization of these logical values in terms of opinion polls. Two different interpretations are plausible for the latest sort of opinion, depending upon whether "non-assertability" refers to incompleteness or inconsistency. It is shown hat the incomplete version of JL_{G} is equivalent to Kleene's logic K3, whereas the (...) inconsistent version of JL_{M} is equivalent to Priest's Logic of Paradox LP. Finally, it is argued that the Indian logics depart from Western logics by conflating truth and justified belief: the different preconditions for belief ascription accounts for the difference between pluralist and skeptic logics.

It is argued that the theory of opposition is in position to contribute as a formal method of conceptual engineering, by means of an increasing dichotomy-making process that augments the number of elements into any structured lexical field. After recalling the roots of this theory and its logical tenets, it is shown how the processes of expansion and contraction of discourse can modify a lexical field and, with it, our collective representation of ideas. This theory can also bring some order (...) to the question of disagreement in philosophical discourse: what do philosophers disagree about; how can we clarify the distinction between verbal disagreement (focused on words) and substantive disagreement (focused on things)? The ensuing construction of conceptual systems will be exemplified through three case studies of philosophy: desire, truth judgment, and the left–right political divide. The construction rules of such systems resort to the theory of opposition, which intends to improve our understanding of what entails either agreement or disagreement about the meaning of concepts. Such a better understanding of philosophical discourse relies on its formalization in terms of closed lexical fields, thereby leading to a comparative analysis of concepts in light of logical relations between their definitions.

The risk posed by anthropogenic climate change is generally accepted, and the challenge we face to reduce greenhouse gas (GHG) emissions to a tolerable limit cannot be underestimated. Reducing GHG emissions can be achieved either by producing less GHG to begin with or by emitting less GHG into the atmosphere. One carbon mitigation technology with large potential for capturing carbon dioxide at the point source of emissions is carbon capture and storage (CCS). However, the merits of CCS have been questioned, (...) both on practical and ethical grounds. While the practical concerns have already received substantial attention, the ethical concerns still demand further consideration. This article aims to respond to this deficit by reviewing the critical ethical challenges raised by CCS as a possible tool in a climate mitigation strategy and argues that the urgency stemming from climate change underpins many of the concerns raised by CCS.

In recent decades Evagrian psychology and asceticism have attracted much attention. It has, however, also become clear that to understand these aspects, it is necessary to observe the greater metaphysical framework to which they relate. Although this framework presents evident parallelisms with other ancient systems of metaphysics, its relations to these systems have not yet been fully brought to light. In this paper, I propose to shed light on central elements of Evagrius’ theory of contemplation and their metaphysical background by (...) drawing on Neoplatonist ideas. To that end, I cross-read passages from the Evagrian corpus and Plotinus’ Enneads, in particular the treatise on contemplation (III 8). In these passages, I identify various conceptual and structural parallelisms that allow us to suppose a common philosophical background to both systems. Based on these parallelisms, I then outline some conclusions for future perspectives in Evagrian scholarship. (shrink)

Cette contribution se propose d’étudier la place qu’occupe la renommée au sein du stoïcisme. Considérée par les stoïciens comme un indifférent préférable, elle a fait l’objet de discussions approfondies au cours de l’histoire de l’école. Cet article tente ainsi de proposer, à partir des sources conservées, une reconstitution terminologique diachronique des différentes notions théorisées par les stoïciens à propos de la bonne réputation. Il cherchera aussi à restituer les débats portant sur son statut au sein de la catégorie des préférables.

Scholars in recent decades have downplayed or completely denied that Evagrius Ponticus has a metaphysical system, instead suggesting that he merely borrows from various philosophies, particularly Stoicism, without a coherent system. In this paper, I propose a different perspective, arguing for a metaphysical and Platonic interpretation. I reconstruct Evagrius’s metaphysics systematically, relate its fundamentals to the environment of the late antique Medio- and Neoplatonic tradition, and show that by establishing the principles and structures of being, Evagrius indeed reveals himself to (...) be a metaphysician.
