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.

Existe-t-il une méthode qui permettrait à l’enquête métaphysique (ou ontologique) de bénéficier des avancées scientifiques et techniques, et qui, inversement et en retour, dans un cercle vertueux, permettrait aux sciences et aux techniques de bénéficier du mode de connaissance philosophique? Dit autrement : y a-t-il une méthode permettant de circuler, sans les confondre, entre ces régimes de rationalité que sont la pensée technique, la pensée scientifique et la pensée philosophique, pour les...

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.

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 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)

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)

" Heidegger and Modernity is an intervention in the Heidegger debate in France which many may see as decisive. Its central claim is that the responses of left Heideggerians to continuing disclosures regarding Heidegger's Nazi affiliations fail to come to terms with central ambiguities in his philosophical responses, both early and late, to modernity and technology. . . . Incisive and hard hitting, Luc Ferry and Alain Renault have condensed in a short and tightly organized book both a judicious and (...) well-informed account of the Heidegger question and an implicit defence of humanism which has a strong political resonance."--Liam O'Sullivan, Political Studies.

It is widely accepted that morality does not demand that we do our very best, but our most significant moral traditions do not easily accommodate this intuition. I will argue that the underlying problem is not specific to any particular tradition. Rather, it will be difficult for any moral theory to account for binary moral concepts like permissible/impermissible while also accounting for scalar moral concepts like better/worse. If only the best is considered permissible, morality will seem either unreasonably demanding or (...) implausibly minimal. But if we draw a line of duty below the optimal, then we must explain how the act that is worse is nonetheless permissible. Some have tried to explain this by appealing to non-moral considerations, and others have appealed to agent-relative moral considerations. I argue that no such approach will work. We should instead exploit the distinction between reasons for performing an act and reasons for holding someone accountable for an act’s performance. This approach will also help to clear up a confusion regarding the notion of a moral demand. (shrink)

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)

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.

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.

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)

What happens when the meaning of life based on a divine revelation no longer makes sense? Does the quest for transcendence end in the pursuit of material success and self-absorption? Luc Ferry argues that modernity and the emergence of secular humanism in Europe since the eighteenth century have not killed the search for meaning and the sacred, or even the idea of God, but rather have transformed both through a dual process: the humanization of the divine and the divinization of (...) the human. Ferry sees evidence for the first of these in the Catholic Church's attempts to counter the growing rejection of dogmatism and to translate the religious tradition into contemporary language. The second he traces to the birth of modern love and humanitarianism, both of which demand a concern for others and even self-sacrifice in defense of values that transcend life itself. Ferry concludes with a powerful statement in favor of what he calls "transcendental humanism"--a concept that for the first time in human history gives us access to a genuine spirituality rooted in human beings instead of the divine.

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.

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.

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.

A general characterization of logical opposition is given in the present paper, where oppositions are defined by specific answers in an algebraic question-answer game. It is shown that opposition is essentially a semantic relation of truth values between syntactic opposites, before generalizing the theory of opposition from the initial Apuleian square to a variety of alter- native geometrical representations. In the light of this generalization, the famous problem of existential import is traced back to an ambiguous interpretation of assertoric sentences (...) in Aristotle's traditional logic. Following Abelard’s distinction between two alternative readings of the O-vertex: Non omnis and Quidam non, a logical difference is made between negation and denial by means of a more fine- grained modal analysis. A consistent treatment of assertoric oppositions is thus made possible by an underlying abstract theory of logical opposition, where the central concept is negation. A parallel is finally drawn between opposition and consequence, laying the ground for future works on an abstract operator of opposition that would characterize logical negation just as does Tarski’s operator of consequence for logical truth.

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)

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.

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.

Our aim is to propose a non-referential semantics for the principle of logical charity: neither logical universalism (one logic, one way of thinking), nor logical relativism (several logics, several ways of thinking) afford an adequate conceptual framework to interpret the meaning of any speech act. But neither of them is totally wrong, either. The point is to know to which extent each of these views is partly right, thus leading to a more consensual but paradoxical-sounding "relative principle of charity". After (...) recalling the theoretical background of logical charity, we suggest a four-valued logic of acceptance and rejection (hereafter: AR4); then we explain how such a non-referential semantics does justice both to the champions of logical charity and its opponents. While endorsing coherence as a precondition for rationality, we argue that such a criterion does not entail that classical logic is a necessary conceptual scheme to interpret the others' beliefs. A better application of charity should take account of the questions implicitly asked by a statement, and we bring these questions out in replacing Quine's truth-functions by Quine’s verdict functions while emphasizing upon their varying degrees of strength.

Because contemporary political philosophy owes a significant debt to the great nineteenth-century German philosophies of history, a sound knowledge of German Idealist philosophy is crucial to an understanding of our own time. In Political Philosophy 2 , Luc Ferry provides not only a thorough introduction to German Idealism and its critics, but also an insightful look at contemporary political philosophy. Ferry begins this second volume of his ambitious three-volume Political Philosophy by considering both the structure and the potential political effects (...) of the various philosophies of history born of German Idealism. He focuses on the key question of whether, and to what extent, the principle of reason may be said to govern the totality of the historically real. This leads to an examination of Hegel's criticism of the moral view of the world and to an assessment of the phenomenological criticism of Hegel put forth by Heidegger and Arendt. (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)

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)

An analogy is made between two rather different domains, namely: logic, and football. Starting from a comparative table between the two activities, an alternative explanation of logic is given in terms of players, ball, goal, and the like. Our main thesis is that, just as the task of logic is preserving truth from premises to the conclusion, footballers strive to keep the ball as far as possible until the opposite goal. Assuming this analogy may help think about logic in the (...) same way as in dialogical logic, but it should also present truth-values in an alternative sense of speech-acts occurring in a dialogue. The relativity of truth-values is focused by this way, thereby leading to an additional way of logical pluralism. (shrink)

A central point of debate over environmental policies concerns how future costs and benefits should be assessed. The most commonly used method for assessing the value of future costs and benefits is economic discounting. One often-cited justification for discounting is uncertainty. More specifically, it is risk aversion coupled with the expectation that future prospects are more risky. In this paper I argue that there are at least two reasons for disputing the use of risk aversion as a justification for discounting (...) when dealing with longterm decisions, one technical and one ethical. Firstly, I argue that technically, it implies an inconsistency between theory and practice. And secondly, I argue that discounting for uncertainty relies on a form of individualism which, while reasonable in standard microeconomic theory where an agent chooses how to spread her own consumption over her own lifetime, is inappropriate in the context of intergenerational social decisions.
