El artículo documenta y analiza las vicisitudes en torno a la incorporación de Hilbert de su famoso axioma de completitud, en el sistema axiomático para la geometría euclídea. Esta tarea es emprendida sobre la base del material que aportan sus notas manuscritas para clases, correspondientes al período 1894–1905. Se argumenta que este análisis histórico y conceptual no sólo permite ganar claridad respecto de cómo Hilbert concibió originalmentela naturaleza y función del axioma de completitud en su versión geométrica, sino que además (...) permite disipar equívocos en cuanto a la relación de este axioma con la propiedad metalógica de completitud de un sistema axiomático, tal como fue concebida por Hilbert en esta etapa inicial.The paper reports and analyzes the vicissitudes around Hilbert’s inclusion of his famous axiom of completeness, into his axiomatic system for Euclidean geometry. This task is undertaken on the basis of his unpublished notes for lecture courses, corresponding to the period 1894–1905. It is argued that this historical and conceptual analysis not only sheds new light on how Hilbert conceived originally the nature of his geometrical axiom of completeness, but also it allows to clarify some misunderstandings regarding this axiom and the metalogical property of completeness of an axiomatic system, as it was understoodby Hilbert in this initial stage.

Sobre la base que aportan las notas manuscritas de David Hilbert para cursos sobre geometría, el artículo procura contextualizar y analizar una de las contribuciones más importantes y novedosas de su célebre monografía Fundamentos de la geometría, a saber: el cálculo de segmentos lineales. Se argumenta que, además de ser un resultado matemático importante, Hilbert depositó en su aritmética de segmentos un destacado significado epistemológico y metodológico. En particular, se afirma que para Hilbert este resultado representaba un claro ejemplo de (...) uno de los rasgos más fructíferos y atractivos de su nuevo método axiomático formal, o sea, la capacidad de descubrir y exhibir conexiones estructurales o internas entre diferentes teorías matemáticas. On the basis of a set of unpublished notes for lecture courses on geometry, the paper seeks to contextualize and analyze one of the most important and original contributions of David Hilbert's celebrated monograph Foundations of Geometry, namely its arithmetic of line segments. It is argued that Hilbert attributed to his arithmetic of segments an important epistemological and methodological meaning, in addition to its relevance as an original mathematical result. In particular, it is claimed that for Hilbert his arithmetic of segments represented a clear example of one of the most fruitful and attractive traits of his new formal axiomatic method, i.e., the power to discover and exhibit inner or structural connections among different mathematical theories.

The paper outlines an interpretation of one of the most important and original contributions of David Hilbert’s monograph Foundations of Geometry , namely his internal arithmetization of geometry. It is claimed that Hilbert’s profound interest in the problem of the introduction of numbers into geometry responded to certain epistemological aims and methodological concerns that were fundamental to his early axiomatic investigations into the foundations of elementary geometry. In particular, it is shown that a central concern that motivated Hilbert’s axiomatic investigations (...) from very early on was the aim of providing an independent basis for geometry. Accordingly, these concerns about an independent grounding for elementary geometry determined very clear methodological constraints in the process of embedding it into a formal axiomatic system. It is argued that Hilbert not only sought to show that geometry could be considered a pure mathematical theory, once it was presented as a formal axiomatic system; he also aimed at showing that in the construction of such an axiomatic system one could proceed purely geometrically, avoiding concept formations borrowed from other mathematical disciplines like arithmetic or analysis.

El artículo presenta una interpretación del abordaje axiomático temprano a la geometría de David Hilbert, i.e., el desarrollado entre 1891 y 1905. Se sostiene que diversos aspectos de este abordaje, a primera vista problemáticos, se pueden comprender mejor si se contrastan con una de sus influencias más importantes en este periodo: la teoría pictórica [Bildtheorie] de Heinrich Hertz. En particular se argumenta que un análisis de la concepción axiomática de Hilbert a la luz de la teoría de Hertz permite aliviar (...) ciertas tensiones en la concepción hilbertiana; más precisamente, las tensiones que surgen de mantener, al mismo tiempo, una posición axiomática abstracta o formal y una concepción empirista de la geometría, que la considera una ciencia natural.

This paper provides a detailed study of David Hilbert’s axiomatization of the theory of plane area, in the classical monograph Foundation of Geometry. On the one hand, we offer a precise contextualization of this theory by considering it against its nineteenth-century geometrical background. Specifically, we examine some crucial steps in the emergence of the modern theory of geometrical equivalence. On the other hand, we analyze from a more conceptual perspective the significance of Hilbert’s theory of area for the foundational program (...) pursued in Foundations. We argue that this theory played a fundamental role in the general attempt to provide a new independent basis for Euclidean geometry. Furthermore, we contend that our examination proves relevant for understanding the requirement of “purity of the method” in the tradition of modern synthetic geometry. (shrink)

El artículo presenta y analiza un conjunto de notas manuscritas de clases para cursos sobre geometría, dictados por David Hilbert entre 1891 y 1905. Se argumenta que en estos cursos el autor elabora la concepción de la geometría que subyace a sus investigaciones axiomáticas en Fundamentos de la geometría . Por un lado, afirmo que lo que caracteriza esta concepción de la geometría es: i) una posición axiomática abstracta o formal; ii) una posición empirista respecto del origen de la geometría (...) y de su lugar dentro de las distintas teorías matemáticas. Por otro lado, sostengo que el papel que Hilbert le confiere a la intuición geométrica en el proceso de axiomatización de esta teoría, permite apreciar claramente su oposición respecto de las posiciones formalistas con las que habitualmente es identificado.

A theory of magnitudes involves criteria for their equivalence, comparison and addition. In this article we examine these aspects from an abstract viewpoint, by focusing on the so-called De Zolt’s postulate in the theory of equivalence of plane polygons (“If a polygon is divided into polygonal parts in any given way, then the union of all but one of these parts is not equivalent to the given polygon”). We formulate an abstract version of this postulate and derive it from some (...) selected principles for magnitudes. We also formulate and derive an abstract version of Euclid’s Common Notion 5 (“The whole is greater than the part”), and analyze its logical relation to the former proposition. These results prove to be relevant for the clarification of some key conceptual aspects of Hilbert’s proof of De Zolt’s postulate, in his classicalFoundations of Geometry(1899). Furthermore, our abstract treatment of this central proposition provides interesting insights for the development of a well-behaved theory ofcompatiblemagnitudes. (shrink)

El artículo ofrece una interpretación de las contribuciones de David Hilbert a la teoría de las magnitudes poligonales, desarrollada en su influyente monografía Fundamentos de la geometría, publicada en 1899. Se argumenta que la construcción de esta parte central de la geometría euclidiana represento para Hilbert un desafío muy significativo, en razón de su objetivo general de proporcionar una axiomatización estrictamente sintética de esta teoría geométrica; es decir, en virtud de sus conocidos requerimientos metodológicos y epistemológicos de construir la geometría (...) elemental evitando toda apelación esencial a presupuestos numéricos. Se sostiene además que dicho desafío consistió en ofrecer un nuevo fundamento lógicamente sólido para la teoría del área poligonal, pero que al mismo tiempo pueda ser considerado como puramente geométrico. The paper offers an interpretation of David Hilbert's contributions to the theory of polygonal magnitudes, developed in his influential monograph Foundations of Geometry, published in 1899. It is argued that the construction of this central part of Euclidean geometry presented an appealing challenge to Hilbert's general aim of providing a purely synthetic axiomatization of this geometrical theory; in other words, to his epistemological and methodological concerns of constructing elementary geometry without resorting to any kind of numerical assumption. Moreover, it is claimed this challenge consisted in offering a new foundation for the theory of polygonal area, which could be considered at the same time as logically sound and purely geometrical.

This paper analyzes the theory of area developed by Euclid in the Elements and its modern reinterpretation in Hilbert’s influential monograph Foundations of Geometry. Particular attention is bestowed upon the role that two specific principles play in these theories, namely the famous common notion 5 and the geometrical proposition known as De Zolt’s postulate. On the one hand, we argue that an adequate elucidation of how these two principles are conceptually related in the theories of Euclid and Hilbert is highly (...) relevant for a better understanding of the respective geometrical practices. On the other hand, we claim that these conceptual relations unveil interesting issues between the two main contemporary approaches to the study of area of plane rectilinear figures, i.e., the geometrical approach consisting in the geometrical theory of equivalence and the metrical approach based on the notion of measure of area. Finally, in an appendix logical relations among equivalence, comparison and addition of magnitudes are examined schematically in an abstract setting. (shrink)

El artículo examina una de las contribuciones más importantes a los fundamentos de la geometría euclídea elemental lograda por David Hilbert en su obra Fundamentos de la geometría, a saber: la reconstrucción de la teoría euclídea de las proporciones y de los triángulos semejantes. Se argumenta que dicha reconstrucción no sólo estuvo motivada por la identificación de Hilbert de suposiciones implícitas en la teoría de Euclides, sino que además estuvo esencialmente ligada a la preocupación por la 'pureza del método'. Más (...) aún, se afirma que, en este caso específico, el requerimiento de Hilbert por la pureza del método posee un carácter general o fundacional, esto es, no se refiere a la demostración de un teorema en particular, sino más bien es planteado respecto de la construcción axiomática de la teoría misma.

The paper surveys different notions of implicit definition. In particular, we offer an examination of a kind of definition commonly used in formal axiomatics, which in general terms is understood as providing a definition of the primitive terminology of an axiomatic theory. We argue that such “structural definitions” can be semantically understood in two different ways, namely as specifications of the meaning of the primitive terms of a theory and as definitions of higher-order mathematical concepts or structures. We analyze these (...) two conceptions of structural definition both in the history of modern axiomatics and in contemporary philosophical debates. Based on that, we give a systematic assessment of the underlying semantics of these two ways of understanding the definiens of such definitions, by considering alternative model-theoretic and inferential accounts of meaning.

This paper aims to offer an interpretation of the Transcendental Deduction of the Categories which puts together two of its most distinctive and fundamental traits: the constant reference to the temporal character of the human consciousness and the use of the analytic method of exposition. We will defend the thesis that the connection between both traits is essential, i. e., it will be argued that it is precisely the usage of the analytic method what confers to the pure consciousness of (...) time a significant role in the structure of the argument. With this thesis an alternative reading of the A-Deduction is pursued, one which moves away from the predominant one which claims that Kant's persistent allusion in it to the pure time representation - and to the synthesis which make it possible - is just a direct consequence of its psychological character.El objetivo del artículo es ofrecer una interpretación de la Deducción Transcendental de las Categorías que ponga en relación dos de sus aspectos más distintivos y fundamentales: la referencia permanente al carácter temporal de la conciencia humana, y la utilización del método analítico de exposición. Se defenderá la tesis de que la conexión entre ambos aspectos es esencial, en tanto que es precisamente la adopción del método analítico lo que determina que se le confiera a la conciencia pura del tiempo un rol fundamental en la estructura del argumento. Con esta tesis se intenta ofrecer una lectura alternativa de la Deducción A, que se diferencie de la habitual según la cual la apelación constante de Kant a la representación pura del tiempo - y a las síntesis que lo hacen posible - es una consecuencia directa del carácter psicologista que la distingue.

The logics of formal inconsistency are logics tolerant to some amount of contradiction, but in which some versions of explosion still hold. The main result of this paper is a reconstruction of two such logics in the dialogical framework. By doing so, we achieve two things. On the one hand, we provide a formal approach to argumentative situations where some contradictions may occur while keeping the idea that there may still be situations in which some propositions are ‘safe’ in the (...) sense of immunity to the contradictions. On the other hand, we open a new line of study on these logics, in the context of the game-theoretical approach to semantics born in the 1960s, with various interesting perspectives, some of which are discussed at the end of this article.

This paper seeks to highlight the methodological contributions developed by Michel Foucault in regard to a critical history. We propose a tour through various passages of the thinker´s work, with the aim of bashing the main elements that allegedly make up his method. From this exercise we maintain that, in order to record the existence of a Foucauldian method, it is necessary to reproblematize this notion beyond the displacements around the well-known three moments of his work -archeological/genealogical/ethical-, reorienting the look (...) towards the critical tension possible to peer around the unique place that occupies the question of history in his work. The novelty of our proposal is to point out that, beyond the well-known substantial contributions foreshadowed around Foucault's conceptual rig, his work must be understood as an eminently practical historical-philosophical methodology, aimed at disarticulating the canonical principles that legitimize knowledge produced by the historiographic method, thus opening a region of indiscernibility and rarity in historical practice that, we maintain, can be thought of in the vicinity of a parahistory. In sum, we propose the thesis that the displacement in Foucault's work takes on a singular power from the introduction of a strategic artifice ― anonymous ―, aimed at forcing a fold of history on itself, showing how historiographical plots actively tax to sustain and legitimize the regimes of knowledge, power and truth present in them.

A theory of magnitudes involves criteria for their comparison, equivalence and addition. We examine these aspects from an abstract viewpoint, stressing independence and definability. These considerations are triggered by the so-called De Zolt’s principle in the theory of equivalence of plane polygons.

Desde que Hegel declarara el arte como “cosa del pasado”, diversas posturas han discutido sus posibilidades de existencia y ocaso, mientras el arte mismo se ha visto en la incomodidad de la indefinición de sus condiciones ontológicas y de sus espacios de circulación. Esa indefinición, no obstante, permitió que ciertas operaciones y modos de hacer artísticos se desplazaran hacia escenarios abiertos y no institucionales. Una vez trazada una ruta hermenéutica desde la estética hegeliana hasta la actualidad, a partir de modelos (...) de análisis como los Estudios visuales, la teoría de Boris Groys o Nicolas Bourriaud, o el sistema modal de Jordi Claramonte, es posible pensar las condiciones de posibilidad actuales del arte en la medida de sus entrecruzamientos y del desplazamiento de su objeto desde la creación hacia la circulación. Sin que haya desaparecido la plataforma de legitimación institucional, las variaciones en las que se despliegan los códigos artísticos en la cultura visual contemporánea desestiman la posibilidad de reclamarse como obras de arte, y se limitan a hacer un uso táctico de formas de relación y producción. De ahí que la demarcación de los escenarios de supervivencia del arte pueda resumirse en el traslado de la categoría arte, como sustantivo, hacia la movilidad versátil del adjetivo artístico.

En tant qu’introduction à son sujet, l’ouvrage est cependant un modèle de clarté et de concision. L’auteur retrace d’abord l’histoire des idées libérales et démocratiques: il présente la querelle des anciens et des modernes au sujet de la liberté, évalue l’impact de la révolution des droits de l’homme et résume les contributions de Mill et de Tocqueville au débat. Dans les derniers chapitres du livre, Bobbio discute les rapports que le libéralisme et la démocratie ont établis avec l’utilitarisme, l’individualisme, l’organicisme (...) et le socialisme. Considéré comme un travail d’introduction, le seul point faible du livre est de ne pas être à jour. (shrink)

Le sentiment que j'ai de moi-meme a-t-il rien de commun avec la perception que les autres ont de moi? Et ce corps, qui me precede toujours, que dit-il a autrui de ma vraie nature, de mes gouts, de mon etre secret?

En d'autres termes: mon corps est-il l'expression de mon moi ou mon moi est-il le prisonnier clandestin de mon (...) corps? Entre moi et ce qui est mien, la relation est donc bien moins d'ordre ontologique que linguistique ou stylistique. C'est ce qui fait du snobisme ou du dandysme deux figures de cet effort que chacun entreprend pour tenter de paraitre ce qu'il voudrait etre, et pour tenter d'affacer ce qui volontairement sien. N.

Sade e Schopenhauer são filósofos que pensaram a matéria ao mesmo tempo em que descartaram o criacionismo. Schopenhauer pensa a matéria e suas formas no interior de sua metafísica da vontade, enquanto Sade é um materialista propriamente dito, que parte da física e leva a sua concepção de matéria às últimas consequências. Em ambos os autores, o que é inerente ao mundo material é o conflito e o desgaste, o horror e a banalidade do mal, bem como a indiferença cósmica (...) inerente aos fenômenos que constituem o mundo. O presente artigo analisa as peculiaridades do materialismo em ambos os autores e interpreta a concepção de Sade à luz do ponto de vista schopenhaueriano. (shrink)

The theme for this volume is social cognition, construed from a psychological and collective point of view. From the psychological point of view, the question is to understand how the human mind processes social information; how it encodes, stores and uses it in the social context. From a collective point of view, the question is to understand how individual cognition is influenced (improved, increased or impaired) by social interactions, for instance in communicating and collaborating with intelligent agents. These two dimensions (...) of social cognition are obviously interdependent: the psychological dimension makes the collective dimension possible, which can in return modify the psychological dimension. The book is divided into four parts. The first part is about socio-cognitive skills. Among those, we count face recognition, imitation learning, embodied social interaction, cheater detection and psychological concept acquisition. The second part is about persons and memories: stereotypes, attraction judgements and impression formation are the subjects at hand. The third part is about understanding each other. A key part of that understanding is the motor system (whether or not we see it as a "mirror"), but community membership itself can also contribute to our understanding of others. The fourth and final part is about social cognition in societies. This section is unified by the common goal of understand how social cognition actually influences the structure of different societies, whether whole cultures, specific social networks, rural communities or even groups of caterpillars!

On reconnait en Castoriadis l'un des principaux penseurs politiques alternatifs contemporains, toujours actuel. Mais on connaît sans doute moins le lien étroit qui existe entre ses analyses politiques et ses prises de position philosophiques. Or, elles s'éclairent réciproquement. Le refus de subordonner la raison pratique à la raison théorique permet à Castoriadis de penser l'idée de création. Sa rupture avec Marx, auquel il reproche son ontologie déterministe, l'amène à repenser l'émancipation politique et sociale à partir de la notion d'imaginaire créateur. (...) Pour bien comprendre cette notion, il faut la confronter avec les conceptions de l'imagination défendues notamment par la phénoménologie, particulièrement Sartre et Husserl. Elle débouche sur le concept de chaos, dont il ressort que l'action humaine repose sur un désordre pour une part irréductible, ce qui explique qu'on ne puisse fonder celle-ci, pas plus que la démocratie, en référence à une légitimité indiscutable. Cherchant à tisser un lien entre la pensée, l'oeuvre et la vie d'un homme engagé dans son temps, ce livre trace un parcours à travers les thèmes centraux de la pensée philosophique et politique de Castoriadis, qu'il met en rapport avec d'autres approches contemporaines : Maurice Merleau-Ponty, Claude Lefort, Richard Rorty, Vincent Descombes, ou encore Michel Foucault à propos de l'éthique du sujet. Un chapitre est également consacré à la place de l'exil dans la vie et la pensée de Castoriadis. (shrink)

Adult stem cell populations must coordinate their own maintenance with the generation of differentiated cell types to sustain organ physiology, in a spatially controlled manner and over long periods. Quantitative analyses of clonal dynamics have revealed that, in epithelia, homeostasis is achieved at the population rather than at the single stem cell level, suggesting that feedback mechanisms coordinate stem cell maintenance and progeny generation. In the central nervous system, however, little is known of the possible community processes underlying neural stem (...) cell maintenance. Recent work, in part based on intravital imaging made possible in the adult zebrafish, conclusively highlights that homeostasis in neural stem cell pools may rely on population asymmetry and long‐term spatiotemporal coordination of neural stem cell states and fates. These results suggest that neural stem cell assemblies in the vertebrate brain behave as self‐organized systems, such that the stem cells themselves generate their own intrinsic niche. (shrink)

The Arabic text of Boethus fr. 44 Rashed has, pace Rashed, a parallel in a Greek scholium to Galen's De elementis ex Hippocratis sententia. The scholium occurs in the sets of scholia to De elem. in Paris BNF suppl. gr. 634 and in El Escorial Φ.II.15. The former set was edited by G. Helmreich in Handschriftliche Studien zu Galen, vol. I. The relevant passage occurs in Π fol. 21 r ult. – v 3 and in Σ fol. 136 r 7-11. (...) The polysyllogism ascribed to Boethus reads: τὸ ὅμοιον ὑπὸ τοῦ ὁμοίου γινώσκεται. ἡ αἴσθησις τὰ στοιχεῖα γινώσκει. ἡ αἴσθησις ἄρα ὁμοία τοῖς στοιχείοις … ἡ αἴσθησις ὁμοία τοῖς στοιχείοις. τὸ ὅμοιον ἐκ τοῦ ὁμοίου [γινώσκεται]. ἡ αἴσθησις ἄρα ἐκ τῶν στοιχείων [γινώσκεται].

Le génocide du Rwanda constitue l'un des événements majeurs du xxe siècle : 800 000 Tutsis et Hutus de l'opposition au « gouvernement intérimaire » rwandais ont été massacrés entre avril et juin 1994. Or, la reconnaissance de ce génocide ne va pas de soi. Cet article analyse les « contre-feux interprétatifs » mis en place selon trois axes : négation du génocide, euphémisation en « guerre tribale », thèse du « double génocide ». La presse dans cette guerre de (...) mémoire a été un vecteur tout à fait essentiel. The genocide in Rwanda was one of the major events of the 20th century: 800, 000 Tutsis and Hutus opposing Rwanda's "interim government" were massacred between April and June 1994. But recognition of this genocide is by no means taken for granted. This article analyses the different interpretations that were brought in to deflect the issue, such as genocide denial, euphemistic references to the genocide as "tribal war­fare" and "double genocide" theory. The role of the press in this "war over memory" was crucial. (shrink)

Nous proposons dans cet article une vision critique des entretiens dans lesquels Pierre Hadot a retracé son propre itinéraire philosophique. Il s’agit de montrer que ces textes suivent dans leurs grandes lignes un fil conducteur défini, trouvant son point de départ dans l’expérience dite du « sentiment océanique ». Nous ferons valoir que la manière dont Hadot a traité ce sujet a poussé certains de ses lecteurs à voir dans son intérêt croissant pour le stoïcisme l’effet d’un a priori immanentiste. (...) Nous montrerons que les interprétations que l’on a faites jusqu’ici du récit autobiographique de Pierre Hadot reposent en définitive sur son caractère bergsonien : l’expérience du sentiment océanique joue vraisemblablement dans ce récit le rôle d’une « intuition philosophique ». L’ensemble de cette réflexion permettra de mettre en exergue un autre motif pour la compréhension de la vie de Pierre Hadot, qui réside dans la question de l’interprétation des textes. (shrink)

Decades of tobacco control initiatives have turned public opinion against cigarette smoking. Smokers, once considered glamorous, are now stigmatized in domains including the workplace. Extant literature lacks scrutiny of smoker stigmatization and devaluation within the job selection process, and mechanisms that lead to such outcomes. Using an experimental design, we empirically examine initial reactions to job applicants’ smoking behaviors within two samples. We show that initial impressions are significantly worse when job applicants smoke versus do not in a store-based context. (...) Moreover, this effect occurs indirectly through perceived likelihood of engaging in counterproductive work behaviors, and is conditional upon respondents’ own attitudes towards smoking. These relationships—similar for customer service and inventory management jobs—are indicative of potential biases within the hiring process. Implications of these findings, and the moral dilemmas they raise around the treatment of smokers, are discussed from the ethical perspective of human resource management. (shrink)
