. We start from the geometrical-logical extension of Aristotle’s square in [6,15] and [14], and study them from both syntactic and semantic points of view. Recall that Aristotle’s square under its modal form has the following four vertices: A is □α, E is , I is and O is , where α is a logical formula and □ is a modality which can be defined axiomatically within a particular logic known as S5 (classical or intuitionistic, depending on whether is involutive (...) or not) modal logic. [3] has proposed extensions which can be interpreted respectively within paraconsistent and paracomplete logical frameworks. [15] has shown that these extensions are subfigures of a tetraicosahedron whose vertices are actually obtained by closure of by the logical operations , under the assumption of classical S5 modal logic. We pursue these researches on the geometrical-logical extensions of Aristotle’s square: first we list all modal squares of opposition. We show that if the vertices of that geometrical figure are logical formulae and if the sub-alternation edges are interpreted as logical implication relations, then the underlying logic is none other than classical logic. Then we consider a higher-order extension introduced by [14], and we show that the same tetraicosahedron plays a key role when additional modal operators are introduced. Finally we discuss the relation between the logic underlying these extensions and the resulting geometrical-logical figures. (shrink)

ome Remarks on the Crisis of Capitalism What are the causes and consequences of the crisis of capitalism ? What are the plausible scenarios forthe outcome of the crisis ? To what extent is the current crisis comparable to that of 1929, and to whatextent does it differ from the crisis of the 1970s ? To what extent can one speak of a crisis of neoliberalism ? These are some of the questions which the authors of The Crisis of Neoliberalism (...) address here. (shrink)

Qu’un interet renouvelé se manifeste aujourd’hui pour la versant épistémologique de l’œuvre de Gaston Bachelard peut se comprendre au regard de l’histoire contemporaine de la philosophie des sciences.Cette histoire a été dominée durant la plus grande partie du XXe siècle par une doctrine – celle de l’empirisme logique – promue à Vienne à la fin des années 1920 par une institution originale, le Cercle de Vienne qui publie son manifeste en 1929, et s’organise comme un mouvement à visée universelle et (...) progressiste – celui de la “conception scientifique du monde”.La tradition française de la philosophie des sciences a pris d’entrée de jeu un tout autre chemin. Si elle ne les a pas ignorées, elle a refusé de souscrire aux thèses majeures du positivisme logique lorsqu’il s’est présenté à elle. Elle a toujours lié étroitement philosophie et histoire des sciences.Dans le titre de ce petit livre écrit durant l’année universitaire 1967-1968 sous la direction de Georges Canquilhem, Dominique Lecourt a avancé l’expression d’“épistémologie historique” pour signaler, à propos de Gaston Bachelard, cette particularité.

D'" agronomie " à " physique quantique ", d'" Avicenne " à " Wittgenstein ", de " bioéthique " à " hasard " et " loi de la nature ", en passant par " neurone ", " Newton ", " Prigogine ", " symétrie "... Bien au-delà de l'inventaire des progrès marquants de l'histoire des sciences, ce dictionnaire, couronné par l'Institut de France, a pour ambition d'introduire ses lecteurs aux réalités de la pensée scientifique. Réflexion philosophique et enquête historique y (...) sont mêlées, mettant au jour les présupposés, ressorts et perspectives philosophiques des théories et des inventions scientifiques. Inédit en poche, ce dictionnaire, qui ne connaît aucun équivalent, s'adresse aux chercheurs, étudiants, ingénieurs ou pédagogues, mais aussi à tous ceux qui s'intéressent aux sciences de la nature et ne se satisfont pas du positivisme dominant. Fruit de la collaboration de près de deux cents chercheurs et universitaires français et étrangers, scientifiques, philosophes, historiens et sociologues, ce dictionnaire est publié sous la direction de Dominique Lecourt, professeur de philosophie à l'Université Denis Diderot-Paris VII où il dirige le Centre Georges Canguilhem.

Diderot ne saurait être considéré comme l’un parmi d’autres des "matérialistes français" du XVIIIe siècle. Sa pensée ne s’inscrit en réalité ni dans la tradition cartésienne ni dans la tradition lockienne en matière de philosophie de la connaissance, contrairement à une tradition d’interprétations qu’on peut faire remonter à Marx dans la Sainte famille et qui s’est illustrée plus près de nous de plusieurs noms. Diderot écrivain, philosophe et encyclopédiste est ici étudié à l’occasion du tricentenaire de sa naissance, à travers (...) ses écrits – publics ou personnels – en cinq leçons ; un hommage par l’un des spécialistes de celui qui incarna peut-être le mieux, de son vivant déjà, le siècle des Lumières.

L'originalité de cet imposant dictionnaire consiste à recouvrir "le domaine entier de l'histoire des sciences nturelles et de la pensée philosophique qui leur est intimement associée". Les notices sur les concepts, institutions, noms propres, etc. sont d'une exceptionnelle richesse. [SDM].

In view of the progress made in recent decades in the fields of stemmatology and the analysis of geometric diagrams, the present article explores the possibility of establishing the stemma codicum of a handwritten tradition from geometric diagrams alone. This exploratory method is tested on Ibn al-Haytham’s Epistle on the Shape of the Eclipse, because this work has not yet been issued in a critical edition. Separate stemmata were constructed on the basis of the diagrams and the text, and a (...) comparison showed no major differences. The greater reliability of a stemma codicum constructed on the basis of the diagrams rather than the text of a mathematical work is discussed and preliminary conclusions are drawn. (shrink)

Janicaud clarifies the project of “overcoming” metaphysics, a project that Heidegger himself recognized as open to innumerable misunderstandings, and Mattei inquires into the major Heideggerian texts produced between 1935 and 1969 to detect the cosmic figure of the Geviert, the initial Fourfold where “earth and sky, the divine ones and the mortals” gather.

À quelle certitude puis-je prétendre dans la connaissance des phénomènes naturels? De quelle nature sont les premiers principes de la connaissance, et comment les connaît-on? Comment une proposition scientifique, en se rapportant à un objet de connaissance, atteste-t-elle ainsi de sa vérité objective? Qu’est-ce qui fait l’unité d’une science en général, au-delà de la multiplicité des connaissances qui la constituent? Sur quel fondement se définissent et se séparent les sciences spéculatives réelles ? En vertu de quelle structure la logique et (...) la métaphysique sont-elles articulées?Telles sont quelques unes des questions fondamentales qui innervent la théorie du savoir de Jean Duns Scot et manifestent l’importance et l’acuité de sa spéculation épistémologique. À ne pas se focaliser sur la seule dimension métaphysique de la pensée du Docteur Subtil, et à la réinscrire bien plutôt à l’intérieur de sa théorie de la connaissance, de ses concepts et de ses problèmes, on pourra s’apercevoir alors qu’au-delà de la refondation de la métaphysique par l’univocité de l’étant, un geste plus important encore s’est produit chez Duns Scot : une autonomisation des principes de la connaissance objective sur la métaphysique, autonomisation qui ouvre un espace métaphysiquement neutre : celui de la pure possibilité objective en général.

The `co-productions' of science and society have undergone dramatic changes in recent decades. However, contrasts between `Mode 1' and `Mode 2' are not compelling inhistorical terms. This essay will argue that, in fact, they offer too naturalistic and a-political a picture.

Janicaud draws a firm connection between Heidegger's philosophical position and his political engagement. He thus goes beyond those writers who attempt to handle the issue of Heidegger's Nazism simply on the level of his personal political judgment, in isolation from his philosophy, by attempting to distinguish rigorously between Heidegger the thinker and Heidegger the man.

We focus on the task of finding a 3D conductivity structure for the DO-18 and DO-27 kimberlites, historically known as the Tli Kwi Cho kimberlite complex in the Northwest Territories, Canada. Two airborne electromagnetic surveys are analyzed: a frequency-domain DIGHEM and a time-domain VTEM survey. Airborne time-domain data at TKC are particularly challenging because of the negative values that exist even at the earliest time channels. Heretofore, such data have not been inverted in three dimensions. In our analysis, we start (...) by inverting frequency-domain data and positive VTEM data with a laterally constrained 1D inversion. This is important for assessing the noise levels associated with the data and for estimating the general conductivity structure. The analysis is then extended to a 3D inversion with our most recent optimized and parallelized inversion codes. We first address the issue about whether the conductivity anomaly is due to a shallow flat-lying conductor or a vertical conductive pipe; we conclude that it is the latter. Both data sets are then cooperatively inverted to obtain a consistent 3D conductivity model for TKC that can be used for geologic interpretation. The conductivity model is then jointly interpreted with the density and magnetic susceptibility models from a previous paper. The addition of conductivity enriches the interpretation made with the potential fields in characterizing several distinct petrophysical kimberlite units. The final conductivity model also helps better define the lateral extent and upper boundary of the kimberlite pipes. This conductivity model is a crucial component of the follow-up paper in which our colleagues invert the airborne EM data to recover the time-dependent chargeability that further advances our geologic interpretation.

Public surveys conducted in many countries report widespread willingness of individuals to donate a kidney while alive to a family member or close friend, yet thousands suffer and many die each year while waiting for a kidney transplant. Advocates of financial incentive programs or “regulated markets” in kidneys present the problem of the kidney shortage as one of insufficient public motivation to donate, arguing that incentives will increase the number of donors. Others believe the solutions lie—at least in part—in facilitating (...) so-called “altruistic donation;” harnessing the willingness of relatives and friends to donate by addressing the many barriers which serve as disincentives to living donation. Strategies designed to minimize financial barriers to donation and the use of paired kidney exchange programs are increasingly enabling donation, and now, an innovative program designed to address what has been termed “chronologically incompatible donation” is being piloted at the University of California, Los Angeles, and elsewhere in the United States. In this program, a person whose kidney is not currently required for transplantation in a specific recipient may instead donate to the paired exchange program; in return, a commitment is made to the specified recipient that priority access for a living-donor transplant in a paired exchange program will be offered when or if the need arises in the future. We address here potential ethical concerns related to this form of organ “banking” from living donors, and argue that it offers significant benefits without undermining the well-established ethical principles and values currently underpinning living donation programs.

did roger bacon and peter john olivi ever meet? We suggest a positive answer to this question. After he became a Franciscan in 1257, Roger Bacon spent ten years at the Franciscan Paris convent. In those years he wrote the De multiplicatione specierum —his most thought-out piece—the Opus majus, Opus minus, and Opus tertium, which he completed by early 1268. It is not clear whether Bacon returned to England after 1268, or remained in Paris until 1280.1 Peter John Olivi wrote (...) the Summa questions in several phases.2 According to Sylvain Piron's chronology, Olivi's questions on Physics should be dated before 1270, and his theory of...

pt. 1. Gaston Bachelard's historical epistemology.--pt. 2. For a critique of epistemology.

This chapter provides an overview of the issues involved in recent debates about the epistemological relevance of emotions. We first survey some key issues in epistemology and the theory of emotions that inform various assessments of emotions’ potential significance in epistemology. We then distinguish five epistemic functions that have been claimed for emotions: motivational force, salience and relevance, access to facts and beliefs, non-propositional contributions to knowledge and understanding, and epistemic efficiency. We identify two core issues in the discussions about (...) such epistemic functions of emotions: First, even though it is plausible that emotions are involved in epistemic processes, it may be doubted whether they really matter for the normative question of what counts as knowledge or justified belief. Second, some of the epistemic functions claimed for emotions in general may only be attributed to some specifically epistemic emotions, which have been present all along in traditional epistemology, albeit under different labels such as ‘intuitions’.

Figure décisive et controversée de l'hégélianisme contemporain, repère pour tant de penseurs français d'avant et d'après-guerre au premier rang desquels Bataille, Lacan et Sartre, Alexandre Kojève apparaît avant tout comme un commentateur de la Phénoménologie de l'Esprit, dont la lecture est le fruit d'un croisement hardi d'heideggerianisme et de marxisme. Demeurent pourtant largement insoupçonnés l'unité et l'enjeu de son projet global : la constitution d'une anthropologie philosophique radicale, finitiste et athée, nouant les catégories existentielle et logique du Désir, de l'Action, (...) du Discours et de l'Histoire. Cet ouvrage constitue donc la première analyse de fond du système philosophique de Kojève. Il ne se propose pas seulement d'approfondir la thèse centrale méconnue de l'Introduction à la lecture de Hegel, livre-somme du légendaire séminaire tenu à l'École pratique des hautes études, mais s'attaque également au vaste opus posthumum de Kojève, que ce soit le tentaculaire "Essai d'une Histoire raisonnée de la philosophie païenne, le gémellaire et plus resserré " Le Concept, le Temps et le Discours", paru en 1990, l'énigmatique Kant, publié en 1973, ou l'essai inédit sur L'Athéisme de 1931. Une large palette d'approches permet d'éclairer les aspects les plus actuels de l'entreprise originale de Kojève - en particulier la portée du thème paradoxal de la " Fin de l'Histoire " - et ses implications dans le champ de la psychanalyse, des sciences humaines, de la déconstruction derridienne, de la théorie littéraire et de la philosophie politique.

O filósofo Dominique Lecourt, nascido em 05 de fevereiro de 1944, em Paris, é professor da Universidade Paris Diderot-7, e discute questões como ética, política e ciência, atentando ao biocatastrofismo e ao cientificismo. Tais questões são pertinentes na presente obra, a qual é dividida em quatro capítulos.

This book explores the interrelationships between optics, vision and perspective before the Classical Age, examining binocularity in particular. The author shows how binocular vision was one of the key juncture points between the three concepts and readers will see how important it is to understand the approach that scholars once took. In the Middle Ages and the Renaissance, the concept of Perspectiva – the Latin word for optics – encompassed many areas of enquiry that had been viewed since antiquity as (...) interconnected, but which a erwards were separated: optics was incorporated into the field of physics (i.e., physical and geometrical optics), vision came to be regarded as the sum of various psycho-physiological mechanisms involved in the way the eye operates (i.e., physiological optics and psychology of vision) and the word ‘perspective’ was reserved for the mathematical representation of the external world (i.e., linear perspective). The author shows how this division, which emerged as a result of the spread of the sciences in classical Europe, turns out to be an anachronism if we confront certain facts from the immediately preceding periods. It is essential to take into account the way medieval scholars posed the problem – which included all facets of the Latin word perspectiva – when exploring the events of this period. (shrink)

During dialog, references are presented, accepted, and potentially reused. Two experiments were conducted to examine reuse in a naturalistic setting. In Experiment 1, where the participants interacted face to face, self-presented references and references accepted through verbatim repetition were reused more. Such biases persisted after the end of the interaction. In Experiment 2, where the participants interacted over the phone, reference reuse mainly depended on whether the participant could see the landmarks being referred to, although this bias seemed to be (...) only transient. Consistent with the memory-based approach to dialog, these results shed light on how differences in accessibility in memory affect the unfolding of the interaction. (shrink)

In a theoretical first part we attempt to articulate the notions of concession, refutation and negation for monological linguistic activity, on the basis among other things of Mœschler's work on conversation. We distinguish the illocutionary act of refutation and the complex intervention of refutation, concession-invention, concession-repetition and concession-quotation. In a second part we analyze the place and role of (descriptive) negation in counter-argumentative texts written by 8- to 12-year-old pupils and adults in an artificial situation. We consider phenomena observed by (...) certain “contradictory” properties of negation in the context of the task in question: namely potential help in generating content by mechanisms of the argumentative law of negation extended to predicates, negation takes the risk polyphonically of argumentative drift. This may explain the fact that it is so rare. (shrink)
