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)

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.

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.

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)

La présente contribution interroge le parcours intellectuel de Gerald A. Cohen, à la fois unifié par son objectif d’émancipation et marqué par des ruptures théoriques. Alors que le livre de Nicolas Vrousalis, The Political Philosophy of G. A. Cohen. Back to Socialist Basics (Bloomsbury, 2015) vise à présenter la construction intellectuelle de Cohen dans son caractère à la fois complet et cohérent, en vue d’affirmer l’unité de sa pensée politique autour d’un projet d’émancipation, établit très clairement les étapes décisives de (...) l’évolution intellectuelle, il nous apparaît qu’il met trop peu l’accent sur les ruptures dans la pensée de Cohen. Nous estimons que si son unité tient à la fois à sa méthode et à l’objectif qu’il a affiché, elle a sensiblement évolué à tel point que certains éléments de son parcours nous paraissent, au moins en partie, incompatibles entre eux. Vrousalis ne parvient pas à saisir pleinement ceci, au sens où il accorde peu d’importance aux phases de transition dans l’évolution de la pensée de Cohen. La présente contribution présente le livre de Vrousalis dans un premier temps et propose dans un deuxième temps une approche complémentaire voire alternative à celle de Vrousalis.

La présente contribution interroge le rapport de la théorie de Marx aux problématiques en termes de justice sociale. Nous proposons une interprétation selon laquelle une théorie de la justice en soi est inutile car idéaliste. Nous la confrontons à une lecture qui implique qu’une critique du capitalisme fondée sur des critères de justice est nécessaire afin d’éviter l’écueil économiste niant l’individualité.

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.

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)

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)

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.

This editorial of the special issue addresses the question of whether/how responses to the Covid-19 pandemic corresponded with authentic CSR. The literature on CSR has tended to endorse a business-centric perspective and its inherent focus on the search for alignments between CSR activities and the economic/financial interests of the firm. The Covid-19 pandemic has put this perspective to the test, pushing many companies to engage in distinctively more genuine and authentic CSR and/or demonstrating the importance of prior CSR engagement in (...) facilitating crisis management. The papers included in the special issue appear to converge on the idea that firms combining evidence of both pre-crisis engagement in CSR and strong CSR performance during the crisis (demonstrated through the deployment of various CSR assets and resources, including certified reporting, social marketing, individual engagement, resilience, legitimacy, trust) have coped better. This provides interested researchers with an opportunity to appreciate the value of CSR during a crisis. (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)

Misunderstanding occurs between speakers when they disagree about the meaning of words in use. In the case of truth-values, Frege took these to be referents of sentences which consist of classes of accepted (i.e. “true”) or rejected (i.e. “false”) sentences. From this usual depiction of truth and falsity, a general algebraic framework is proposed to systematize the use of truth-values from a dialogical point of view of logic. A special attention will be paid to two radically opposed pseudo-speakers: Heraclites and (...) Nagarjuna, according to whom truth-values respectively refer to everything or nothing. Finally, dialectical (pseudo-Hegelian) negation will be rendered as a very special function: an ontological object-forming operator, similar to the arithmetic successor-forming operator Sn+1(x) on integers and consistent within our generalized theory of truth-values as variable referents.

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.

Is Yogācāra a system of idealist metaphysics or a theory of experience without metaphysical commitments? An increasing amount of literature has argued, since the 1980s, in favor of the second answer. In this paper, I propose to review the background to the question. In fact, most of the attempts to answer the question have been made with reference to Buddhist texts and concepts. However, labels such as “idealism” emerged from Western philosophy and are reflective of specific historical situations and problems. (...) Extending their use to other contexts requires that these specificities are taken into account. Building on an historical survey, I suggest that some essential features of Yogācāra correspond to features of an ancient Greek tradition of metaphysics that has been characterized as idealist: Neoplatonism. On this basis, I come back to the initial question and argue in favor of the idealist interpretation. (shrink)

Key activities in biomedicine and related research rely on collections of biological samples and related files. Access to such resources in industry and in academic contexts has become strategic and represents a central issue in the general framework of rising patenting practices and in debates about the knowledge economy. It raises important issues concerning the organisation of scientific and medical work, the outline of data-sharing guidelines, and science policy's contribution to the elaboration of an adapted framework. This paper presents an (...) ethnographic study of three French human biobanks. Building on field work (participant observation and in-depth interviews), the study focuses on data access in the concrete practices in biobanks. The paper develops a perspective based on an analysis of different exchange regimes. We argue that access practices are submitted to the different regimes that can coexist and be articulated within the daily activities of each biobank. We also discuss how this perspective can further our understanding of biomedical research, and how it might inform data access policy. (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.

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)

Hugh MacColl is commonly seen as a pioneer of modal and many-valued logic, given his introduction of modalities that go beyond plain truth and falsehood. But a closer examination shows that such a legacy is debatable and should take into account the way in which these modalities proceeded. We argue that, while MacColl devised a modal logic in the broad sense of the word, he did not give rise to a many-valued logic in the strict sense. Rather, his logic is (...) similar to a “non-Fregean logic”: an algebraic logic that partitions the semantic classes of truth and falsehood into subclasses but does not extend the range of truth-values.

Cette note entend faire une critique constructive de la thèse du « mode de production managérial », due à Gérard Duménil et Dominique Lévy. Tout en reconnaissant les mérites de leurs travaux, la note essaye de montrer qu’il existe une disproportion entre leur proposition théorique, de grande ampleur, et sa base empirique, trop faible pour la soutenir. Trois contre-arguments sont développés en ce sens. D’abord, les auteurs ne se fondent pratiquement que sur le constat de la montée de la part (...) des salaires dans les hauts revenus aux États-Unis, une évolution qui peut être remise en cause en catégorisant correctement les revenus des cadres dirigeants. Ensuite, ils négligent des données et des indicateurs alternatifs qui donnent des images fort différentes de l’évolution historique. Enfin, ils n’étudient pas l’évolution des formes organisationnelles qui sont au fondement des théories sur l’évolution de la structure de classe, qui relativisent l’importance de la bureaucratie. Deux contreexemples sont données à l’encontre de la thèse du managérialisme : les associés des fonds de capitalinvestissement constituent des nouveaux capitalistes financiers ; les dirigeants des plus grandes entreprises multinationales sont des dirigeants actionnaires.

Abstract : A measurement result is never absolutely accurate: it is affected by an unknown “measurement error” which characterizes the discrepancy between the obtained value and the “true value” of the quantity intended to be measured. As a consequence, to be acceptable a measurement result cannot take the form of a unique numerical value, but has to be accompanied by an indication of its “measurement uncertainty”, which enunciates a state of doubt. What, though, is the value of measurement uncertainty? What (...) is its numerical value: how does one calculate it? What is its epistemic value: how one should interpret a measurement result? Firstly, we describe the statistical models that scientists make use of in contemporary metrology to perform an uncertainty analysis, and we show that the issue of the interpretation of probabilities is vigorously debated. This debate brings out epistemological issues about the nature and function of physical measurements, metrologists insisting in particular on the subjective aspect of measurement. Secondly, we examine the philosophical elaboration of metrologists in their technical works, where they criticize the use of the notion of “true value” of a physical quantity. We then challenge this elaboration and defend such a notion. The third part turns to a specific use of measurement uncertainty in order to address our thematic from the perspective of precision physics, considering the activity of the adjustments of physical constants. In the course of this activity, physicists have developed a dynamic conception of the accuracy of their measurement results, oriented towards a future progress of knowledge, and underlining the epistemic virtues of a never-ending process of identification and correction of measurement errors.

This article discusses the definitions of ‘‘measurement uncertainty” given in the three editions of the International Vocabulary of Metrology (VIM) and a fourth definition which was suggested for the next edition of this document. It is argued that none of the definitions is satisfying. First, a thorough definition of measurement uncertainty should supply an explanation about the meaning of the concept, which is missing from the VIM2&3. Secondly, when provided, the meanings are not accurate enough: the VIM1 version is flawed (...) and the possible future definition appeals to an overly restrictive notion of ‘‘belief”. Alternative options are then proposed, based on the conclusions that (i) measurement uncertainty is a statement – an inference – made by the experimenter about the measurand; (ii) it is only based on what is accessible to one’s knowledge, and therefore rests on the hypothesis that no unknown systematic error affects the measurement.

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.

Ce texte est une proposition d’interprétation des liens, substantiels, conceptuels et théoriques, qui existent entre ce qu’il est possible de nommer économie et ce que nous nommons poésie. Notre hypothèse est qu’économie et poésie fonctionnent de la même manière du fait d’une contrainte ontologique forte imposée à la poésie. La modernité poétique essaie de s’en défaire et donc le poétique est un art récent.

This special issue on Logic and Law consists of four research papers and one interview focusing on epistemological reflections on relationships between logic and law, whether in a reductionist or complementary approach. Logic aims to elucidate through formal frameworks, yet it often grapples with the intricate nuances of everyday legal discourse. While law endeavors to delineate permissible conduct within defined jurisdictions, it often encounters challenges stemming from the ambiguity of terms, leading to frequent judicial interpretations and the perception that proliferating (...) exceptions undermines the efficacy of the rule itself.

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.

Acoustic speech output results from coordinated articulation of dozens of muscles, bones and cartilages of the vocal mechanism. While we commonly take the fluency and speed of our speech productions for granted, the neural mechanisms facilitating the requisite muscular control are not completely understood. Previous neuroimaging and electrophysiology studies of speech sensorimotor control has typically concentrated on speech sounds (i.e., phonemes, syllables and words) in isolation; sentence-length investigations have largely been used to inform coincident linguistic processing. In this study, we (...) examined the neural representations of segmental features (place and manner of articulation, and voicing status) in the context of fluent, continuous speech production. We used recordings from the cortical surface (electrocorticography (ECoG)) to simultaneously evaluate the spatial topography and temporal dynamics of the neural correlates of speech articulation that may mediate the generation of hypothesized gestural or articulatory scores. We found that the representation of place of articulation involved broad networks of brain regions during all phases of speech production: preparation, execution and monitoring. In contrast, manner of articulation and voicing status were dominated by auditory cortical responses after speech had been initiated. These results provide a new insight into the articulatory and auditory processes underlying speech production in terms of their motor requirements and acoustic correlates. (shrink)

abstract: One of the most prolific approaches to the comparative study of Buddhist and Christian philosophy has been the use of Buddhist anti-metaphysicism to overcome the allegedly obsolete metaphysical discourse of Christianity. This approach has been practiced, among others, by Edgar Bruns, Frederik Streng, Joseph O'Leary, and John Keenan. Keenan's 1980–1990s seminal works were determinative in that they appeared to rely on intuitive and evident premises: Christianity became infused with Greek metaphysical concepts early on; consequently, it adopted the forms of (...) essentialism and ontological discourse practiced in metaphysics. That discourse has now become obsolete and must be overcome; Buddhist anti-metaphysicism helps overcome it; hence, Christianity can learn from Buddhism. In this paper, I show that although Keenan presents the first of these claims as self-evident, it is in fact highly polemical. Its origins lie in Albrecht Ritschl's and Adolf von Harnack's Hellenization theory. While the theological and historical background to this theory has been debated, Keenan does not engage in these debates. Even more, he transforms the theory in such a way that it becomes incongruent with its inherent aim. Following the problems implied on these two levels, I suggest that Keenan's project makes itself vulnerable to incoherencies. In the end, I argue for the overcoming of antimetaphysicism as a basis for Buddhist-Christian dialogue. (shrink)
