Les deux documents présentés sont issus respectivement du dossier de carrière d’une institutrice guadeloupéenne (1957-1962) et de la correspondance privée de celle-ci avec son mari (1961-1962). Tous deux éclairent le racisme auquel ont pu faire face les femmes qui ont migré des DOM-TOM vers la métropole dans les années 1950-1960 au sein de deux espaces sociaux différents : le travail en contact avec un public et les relations familiales au sein des couples mixtes. Notre commentaire met en lumière la complexité (...) des processus de racialisation à l’œuvre dans ce cas et plaide pour un renouveau des recherches sur l’immigration des personnes originaires d’Outre-mer en métropole qui s’intéresseraient spécifiquement à leur intégration au monde de travail.

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)

Science communication, as a field and as a practice, is fundamentally about knowledge distribution; it is about the access to, and the sharing of knowledge. All distribution brings with it issues of ethics and justice. Indeed, whether science communicators acknowledge it or not, they get to decide both which knowledge is shared, and who gets access to this knowledge. As a result, the decisions of science communicators have important implications for epistemic justice: how knowledge is distributed fairly and equitably. This (...) paper presents an overview of issues related to epistemic justice for science communication, and argues that there are two quite distinct ways in which science communicators can be just in the way they distribute knowledge. Both of these paths will be considered before concluding that, at least on one of these accounts, science communication as a field and as a practice is fundamentally epistemically unjust. Possible ways to redress this injustice are suggested. (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)

On cherche ici à saisir la façon dont l'élucidation progressive de la philosophie des formes symboliques devrait conduire Cassirer à s'éloigner de la problématique de la fonction conceptuelle propre à Substance et Fonction. Il apparaîtra que la logique des relations mise en place par l'étude du concept scientifique est reconduite, sous une forme plus subtile, dans l'analyse de toutes les formes symboliques. The goal of this article is to investigate the way in which Cassirer's progressive elucidation of symbolic forms should (...) have caused him to move away from the problem of conceptual function he posed in Substanzbegriff und Fonktionsbegriff. It will be shown, however, that the logic of relations established in his study of the scientific concept pervades, in a more subtle form, his definition of all the symbolic forms. (shrink)

Quels furent les relations de Christiaan Huygens avec les chimistes qu'il eut l'occasion de fréquenter pendant son séjour parisien? A l'examen, elles furent moins distantes que ne le laissent supposer les quelques déclarations fracassantes qui parsèment sa correspondance. Néanmoins, il est difficile d'affirmer qu'il y eut, entre Huygens et la pensée chimique en général, une sympathie qui aurait pu aller au-delà des rencontres individuelles.

English summary: Jan Lukasiewicz (1878-1956) was one of the most important members of the Lwow-Warsaw school of logic. The thirteen translated articles in this volume demonstrate the protean form of Lukasiewiczs work, from his texts on Aristotle and the principle of non-contradiction and syllogistics to modal logic, intuitionism, and multivalent logics. The articles show in particular his preoccupations with logical precision and the problem of human liberty. French description: Avec Kazimierz Twardowski, Stanislaw Lesniewski et Alfred Tarski, le logicien et philosophe (...) polonais Jan Lukasiewicz (1878-1956) est l'un des membres les plus importants de l'Ecole de Lvov-Varsovie. Celebre pour ses ouvrages consacres a Aristote, notamment sur le principe de non-contradiction et sur la syllogistique, il a egalement publie des articles majeurs sur la logique propositionnelle, la logique modale, l'intuitionnisme et les logiques multivalentes, dont il fut l'un des fondateurs. Enfin, il a contribue a faire reconnaitre l'importance des travaux en logique de l'ecole megarico-stoicienne, trop longtemps eclipses par ceux d'Aristote sur la syllogistique. Mais Lukasiewicz ne fut pas seulement un logicien et un historien brillant, il s'engagea aussi dans les polemiques philosophiques de son temps. Il defendit ainsi la methode logique en philosophie. Proche sur ce point des membres du Cercle de Vienne, il ne rejetait pas pour autant les questions metaphysiques, commecelle du determinisme qui l'occupa toute sa vie. Les treize articles de ce recueil, fruit d'un travail collectif de traduction, ont pour ambition de montrer le caractere proteiforme de l'oeuvre de Lukasiewicz, preoccupe autant par la precision logique que par le probleme de la liberte humaine.

Ce bref article décrit une œuvre contemporaine conçue comme un « bricodage » conduisant une IA à bégayer des semblants de phrases en italien. Dislessia joue de la confusion entre la composante syntaxique du langage que semblent maîtriser les IA génératives et la dimension sémantique vectrice de sens qui leur sont inaccessibles.

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.

A general framework for translating various logical systems is presented, including a set of partial unary operators of affirmation and negation. Despite its usual reading, affirmation is not redundant in any domain of values and whenever it does not behave like a full mapping. After depicting the process of partial functions, a number of logics are translated through a variety of affirmations and a unique pair of negations. This relies upon two preconditions: a deconstruction of truth-values as ordered and structured (...) objects, unlike its mainstream presentation as a simple object; a redefinition of the Principle of Bivalence as a set of four independent properties, such that its definition does not equate with normality.

Il s’agit de comprendre dans cet article l’opposition formulée par Gilles-Gaston Granger entre deux types de négation : la négation « radicale », d’un côté, et les négations « appliquées » de l’autre. Nous examinerons les propriétés de cette opposition, ainsi que les enseignements à en tirer sur la philosophie de la logique de Granger. Puis nous proposerons une théorie constructive des valeurs logiques considérées comme des objets structurés, consolidant à la fois l’unité de la théorie logique de Granger et (...) son pluralisme philosophique.

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.

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)

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.

L’enjeu : (...) éprouver « de l’intérieur » des outils contemporains comme l’IA pour « escompter ensuite analyser et déconstruire leurs effets ». (shrink)

The present paper wants to develop a formal semantics about a special class of formulas: quantifying statements, which are a kind of predicative statements where both subject- and predicate terms are quantifier expressions like ‘everything’, ‘something’, and ‘nothing’. After showing how talking about nothingness makes sense despite philosophical objections, I contend that there are two sorts of meaning in phrases including ‘thing’, viz. as an individual (e.g. ‘some thing’) or as a property (e.g. ‘something’). Then I display two kinds of (...) logical forms for quantifying statements, depending on how these ‘thing’s are ordered into a whole predication. Finally, an algebraic semantics is proposed for the finite set of quantifying statements to order these into a (fragmentary) dodecagon of logical relations. The corresponding Sub-Model Semantics (hereafter: $$\mathbb {SMS}$$ ) aims to update the usual theory of opposition whilst leading to a research program for other kinds of statement like categorical and even modal propositions.

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.

The objective of this article is to develop a faith development perspective on corporate sustainability. A firm’s management of sustainability is arguably determined by the way decision-makers relate to the other and the natural environment, and this relationship is fundamentally shaped by faith. This study advances theoretical understanding of the approach managers take on sustainability issues by explaining how four distinct phases of faith development—improvidence, obedience, irreverence and providence—determine a manager’s disposition towards sustainability. Combining insights from intentional and relational faith (...) development theories, the analysis reveals that a manager’s faith disposition can be measured according to four interrelated process criteria: (1) connectivity as a measure of a manager’s actual engagement and activities aimed at relating to sustainability; (2) inclusivity as a measure of who and what is included or excluded in a manager’s moral consideration; (3) emotional affinity as a measure of a manager’s sensitivity and affection towards the well-being of others and ecological welfare; and (4) reciprocity as a measure of the degree to which a manager is rewarded for responding to the needs and concerns of ‘Others’, mainly in the form of a positive emotional (and relational) stimulus. The conceptual model consolidates earlier scholarly works on the psychological drivers of sustainability management by illuminating our search for a process of faith development that connects with an increasingly complex understanding of the role of business in society.

In Coogan's Bluff (1968) and the Dirty Harry films, Clint Eastwood's characters often invoke luck when they want unpredictable others to assume some responsibility to stop violence, thereby implicating moral luck in heroism. In the famous ‘Do I feel lucky’ scene from Dirty Harry (1971), Eastwood's character might not be bluffing, but he is giving luck a role in justice. In this case and others, his character's unconventional responsibility should prompt reconsideration of his character's virtue. Viewers must also decide where (...) the deceptive or rule-breaking policeman locates the responsibility for his actions. (shrink)

“I don’t believe what people say to me, I believe the way they say it,” Christian Bobin said. “This is where the sonic is located, in the manner of speaking, in the way in which bodies move and silences occur.”It would be hard to argue that sound is something the public or professionals, whose work is to create sound, actually think about carefully and consciously, as strange as this might seem. Sound in film is rarely addressed from a theoretical perspective. (...) Few books are dedicated to it beyond purely technical works, and those do not often consider the aesthetic conditions of sound production. The question of the existence of sound is abandoned in favor of normalizing procedures for producing it, absent any... (shrink)

The concept of legal gap is tackled from a number of logical perspectives and semantic methods. After presenting our own goal (Section 1), a first introduction into legal logic refers to Bobbio’s works and his formalization of legal statements (Sections 2 and 3). Then Woleński’s contribution to the area is taken into account through his reference to the distinction between two juridical systems (viz. Common Law vs Civil Law) and the notion of conditional norms (Section 4). The notion of reason (...) is also highlighted in the case of Raz’s legal logic, thereby leading to a future connection with von Wright’s logic of truth and an analogy made with an anti-realist reading of truth-values and norms (Section 5). Our personal contribution is introduced through a reflection on how logic should deal with the logical form of norms (Section 6), before entering a number of crucial definitions and distinctions for the concepts of norm, legal statement, and promulgation (Section 7). The final point is a proposed semantics for legal statements, which is both many-valued and gap-friendly (Section 8). A distinction between a number of requirements for permission and forbiddance leads to a set of non-classical juridical systems in which non-permission and forbiddance are not equivalent with each other any more; this does justice to Woleński’s former distinction between Common Law and Civil Law, also leading ultimately to a non-classical square of legal oppositions in which several legal operators may collapse into other ones (Section 9).

In this article, we present our work to provide a navigation and localization system on a constrained humanoid platform, the NAO robot, without modifying the robot sensors. First, we tried to implement a simple and light version of classic monocular Simultaneous Localization and Mapping algorithms, while adapting to the CPU and camera quality, which turned out to be insufficient on the platform for the moment. From our work on keypoints tracking, we identified that some keypoints can be still accurately tracked (...) at little cost, and used them to build a visual compass. This compass was then used to correct the robot walk because it makes it possible to control the robot orientation accurately. (shrink)

Evagrius famously characterises divine nature as γνῶσις οὐσιώδης, ‘substantial knowledge’. In the Alexandrian, Cappadocian, and other intellectual contexts informed by Platonic, Aristotelian, and Philonic thought, characterisations of God as a noetic or intellectual being are fairly common. However, these traditions concur in using the term νοῦς rather than γνῶσις. How can we explain that Evagrius deviates from the metaphysical mainstream? In this paper, I review this question from an historical and systematic point of view. I propose to examine ancient theories (...) of Mind about the function and structure of the νοῦς, compare them to the Evagrian theory, and identify a possible explanation for the substitution of γνῶσις to the νοῦς. Since God is the key element in Evagrius's metaphysics, a clearer vision of the divine essence will help us appreciate the whole system more fully. (shrink)

A formal theory of oppositions and opposites is proposed on the basis of a non- Fregean semantics, where opposites are negation-forming operators that shed some new light on the connection between opposition and negation. The paper proceeds as follows. After recalling the historical background, oppositions and opposites are compared from a mathematical perspective: the first occurs as a relation, the second as a function. Then the main point of the paper appears with a calculus of oppositions, by means of a (...) non-Fregean semantics that redefines the logical values of various sorts of sentences. A num- ber of topics are then addressed in the light of this algebraic semantics, namely: how to construct value-functional operators for any logical opposition, beyond the classical case of contradiction; Blanché's "closure problem", i.e., how to find a complete structure connecting the sixteen binary sentences with one another. All of this is meant to devise an abstract theory of opposition: it encompasses the relation of consequence as subalternation, while relying upon the use of a primary "proto- negation" that turns any relatum into an opposite. This results in sentential negations that proceed as intensional operators, while negation is broadly viewed as a difference-forming operator without special constraints on it. (shrink)

One of the most prominent myths in analytic philosophy is the so- called “Fregean Axiom”, according to which the reference of a sentence is a truth value. In contrast to this referential semantics, a use-based formal semantics will be constructed in which the logical value of a sentence is not its putative referent but the information it conveys. Let us call by “Question Answer Semantics” (thereafter: QAS) the corresponding formal semantics: a non-Fregean many-valued logic, where the meaning of any sentence (...) is an ordered n-tupled of yes-no answers to corresponding questions. A sample of philosophical problems will be approached in order to justify the relevance of QAS. These include: (1) illocutionary forces, and the logical analysis of speech-acts; (2) the variety of logical negations, and their characterization in terms of restricted ranges of logical values; (3) change in meaning, and the use of dynamic oppositions for belief sets.
