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)

R. M. Messner écrivait encore en 1942 que l'homme moderne regarde le moyen age âge à peu près avec le même sentiment que l'adulte les jours de son enfance. Il entreprenait alors la tâche, qui semblait certes à beaucoup un anachronisme ou un contresens impardonnable, de comparer Duns Scot et Kant. Pour ne pas être suspect aux yeux des modernes il prenait garde de les avertir que son seul souci était de mettre les solutions du Doctor Subtilis en rapport avec (...) les problèmes que les modernes se sont posés. Toutefois, il nous avertissait qu'il ne se laisserait pas guider par l'arrière-pensée de proposer les solutions de Duns Scot comme solutions aux problèmes que Kant avait posés mais auxquels il ne pouvait pas répondre.

Une théorie de la justice peut-elle être métaphysiquement neutre ? John Rawls, aussi bien dans l’article de 1985 « La théorie de la justice comme équité : une théorie politique et non pas métaphysique » que dans son Libéralisme politique a soutenu qu’une théorie de la justice qui s’applique à une société libérale démocratique ne doit s’appuyer sur aucune doctrine compréhensive, mais doit au contraire s’en tenir à des règles de la vie politique et de la répartition des biens qui (...) soient métaphysiquement neutres. Prenant le contre-pied de la position de Rawls, cet article tente de montrer non seulement qu’une telle neutralité ne se vérifie pas dans la construction rawlsienne, lorsqu’il s’agit notamment de justifier les droits de l’homme, mais encore que cet « échec » est ce qui conserve à la théorie de Rawls toute sa force critique par rapport aux doctrines rivales comme l’utilitarisme. Is it possible for a theory of justice to be metaphysically neutral ? John Rawls, in his paper published in 1985 and titled “Justice as Fairness : Political, not Metaphysical”, as well as in his book Political Liberalism published in 1995, defended the thesis that a theory of justice which is supposed to be applied to a liberal and democratic society should not be rooted in a comprehensive doctrine, but, on the contrary, must be confined to a formulation of rules of political conduct and repartition of goods which is metaphysically neutral. From an alternative standpoint, this paper is an attempt to show that such neutrality is not verified in Rawls’ argumentation, especially when human rights’ justification is concerned, and that this failure in implementing neutrality is what helps to preserve all the critical strength of Rawls’ theory as compared to other doctrines as utilitarianism.

From 2009 to 2013 the workplace innovation project “My Enterprise 2.0” was carried out in the region of Utrecht in the Netherlands in order to strengthen the workplace innovation capability of small and medium-sized enterprises. Participating enterprises completed a questionnaire regarding the “workplace innovativeness” of their company. A workplace innovation intervention was then implemented by some of the companies, while other companies chose not to take part. At the end of the project, a second questionnaire indicated that those companies that (...) implemented interventions had a significantly higher score with regard to overall workplace innovativeness. The companies without such interventions reported a small decrease. While the companies in the region had higher workplace innovativeness scores relative to a national reference group both before and after the project, the increase in the “workplace innovativeness” of the regional SMEs that experienced interventions suggests that the project proved beneficial to their continued “workplace innovativeness.” Moreover, these companies also reported positive effects on company performance, achieving company goals and improving labor productivity.

Selections from the writings of Ernest Renan, a leading French writer and thinker of the 19th century.

In philosophy, the decolonization of knowledge is marked by a number of “quarrels” related to its history, its geography, its location, its modality of production, its subjects and its objects. There are usually questions about the existence of non-Western philosophies, their place in the canons of the historiography of philosophy, and the curricula of philosophy in the West and elsewhere. There is also the question of the methodological and conceptual modalities according to which the philosophical discourses of the colonized people (...) are constructed when it comes to being situated in relation to the philosophies of the dominant societies. African philosophy is a laboratory to illustrate the dead ends of any decolonization of knowledge and also to examine the conditions of possibility of such a decolonial approach. (shrink)

At the most basic class impulse in the bud, hope is something beyond the mere impulse class, it has absorbed the fantastic imagination, ideological presumption is capacity. Hope is the most remarkable people the impulse to want to work with the community, awareness of the concept of composition and properties constitute a part of our anthropological basis. But those who hope in the imagination of people. The history of mankind is not only a history of class struggle, including also a (...) hope, planning, pre-presumption, poetry, education, philosophical discourse, political programs and struggles of history. Looking for hope and have every kind of political significance. Presumption is - hope - a dream not only the scope of Marxism is the political reality of the scope of the revolution. (shrink)

DANS QUELLE MESURE LES CARACTERISTIQUES DE LA NOTION RENANIENNE DE LA SCIENCE CORRESPONDENT-ELLES D'UNE PART AU COURANT REDUCTIONNISTE, D'AUTRE PART A L'IDEE SYNTHETISANTE OU GLOBALISANTE QUI SE FORMULE EN TERMES D'INSATISFACTION ET D'EXIGENCES A RESONANCE ROMANTIQUE? VAUT-IL LA PEINE D'ETUDIER L'UVRE RENANIENNE DANS L'OPTIQUE DE NOS CONNAISSANCES SUR L'HISTOIRE DES IDEES AU XIXE SIECLE? PEUT-ON PARLER DE L'ACTUALITE DE LA PENSEE DE RENAN AUJOURD'HUI QUAND LES PREOCCUPATIONS EPISTEMOLOGIQUES CONTINUENT A DOMINER LA REFLEXION PHILOSOPHIQUE? LA PENSEE DE RENAN HESITE ENTRE L'EPISTEMOLOGIE (...) REDUCTIONNISTE, ALIMENTEE PAR LES RESULTATS DES SCIENCES EXPERIMENTALES, ET L'ATTITUDE GLOBALISANTE SOUHAITANT DONNER A LA CONNAISSANCE LA TOTALITE COMME OBJET. LA SCIENCE DE GALILEE, DE NEWTON ET DE LAPLACE A REDUIT LA RICHESSE INDIVIDUELLE DES PHENOMENES A DES CAS IDEALISES, PRIVES EN PREMIER LIEU DE LEUR HISTOIRE. C'EST LE TEMPS-DEVENIR QUI REVENDIQUE SES DROITS DANS CETTE CONCEPTION ETAYEE PAR LA PHILOSOPHIE ALLEMANDE. POSITIVISME ET ROMANTISME DESIGNENT CHEZ RENAN LES DEUX POLES D'UN CONFLIT D'ORDRE EPISTEMOLOGIQUE. IL SERAIT PREFERABLE DE REMPLACER DORENAVANT CES TERMES PAR REDUCTIONNISMEET GLOBALISME EPISTEMOLOGIQUES. LA METHODE DOUBLE SUGGEREE PAR RENAN, COMPOSEE DE RIGUEUR ET DE FINESSE SIGNIFIE QU'IL A PRIS CONSCIENCE DE LA CAUSE QUI PRESIDAIT A L'INSUFFISANCE DE LA DEMARCHE REDUCTIONNISTE : IL S'EST RENDU COMPTE QUE LE TEMPS-DEVENIR DEVAIT ENTRER DANS LA DEFINITION DE L'OBJET SCIENTIFIQUE. LA PENSEE DE RENAN, AVEC TOUT SON ATTACHEMENT A DES FORMULES QUI SEMBLENT AUJOURD'HUI AVOIR VECU, EST UNE PROMESSE NON TENUE : L'ELABORATION RIGOUREUSE DE SES IDEES AURAIT PU DONNER NAISSANCE A UN SYSTEME EPISTEMOLOGIQUE UNIFIE DE LA SCIENCE.
