Després del centre de El polític, dedicat a la justa mesura, el diàleg imposa el «retorn al polític» i ja no se separarà més d’aquesta comesa. Es procedirà, en primer lloc a depurar les arts concausants; després se separaran les diferents menes de servidors de la ciutat, per tal d’arribar a veure que els rivals del polític conformen un conjunt de difícil separació. Caldrà, abans de prosseguir amb la divisió, atendre als tipus de règim polític per veure quin paper hi (...) juga el saber polític. El resultat d’aquest primer moment del retorn al polític pren la figura de la descoberta dels fonaments de la ciutat. (shrink)

Llegados al final del periplo para definir al rey y al político, el Forastero y el joven Sócrates se encuentran en un callejón sin salida; no han podido determinar el perfil de cada uno de ellos. La narración del mito será la enmienda del método utilizado hasta ahora, i.e. la diéresis o división, que los ha llevado a una situación aporética. El Forastero muestra que se han cometido dos errores a lo largo del recorrido: el primero ha sido confundir lo (...) humano con lo divino; el segundo, de más envergadura, no establecer claramente la manera cómo el rey y el político podían ser el gobernante de la ciudad entera. Éste es uno de los pasajes más relevantes del Político de Platón, pues en él se realiza una reflexión sobre la naturaleza del error cometido. (shrink)

Le Lysis est l’histoire d’un ruban, d’un nœud qui se tresse et se détresse. L’étude d’Antoni Bosch-Veciana pivote autour de l’interpré­tation du dialogue comme figuration d’une scène où l’on établit une synousia, un lien, qui se défait à la fin (dielusamen). La clef de voûte de l’ouvrage est le mot synousia. « Si, en effet, on prête attention à l’en­semble du Lysis à partir de l’affirmation finale, le διελύσαμεν τὴν συνουσίαν de 223b3 (dissolguérem la reunió [« nous avons dissous la (...) réu­nion...

La prise de conscience de l’héritage de précompréhensions communes avec lesquelles le lecteur d’aujourd’hui tente d’accéder au texte, cet éclaircissement de notre situation interprétative, ouvre dans le travail que nous commentons ici la pos­sibilité de signaler aussi les apories et les vides qui demeurent non résolus, qui se manifestent soit dans les accords soit dans les querelles qui dominent la tradition interprétative du dialogue et qui mettent l’accent, dans tous les cas, sur leur insuf...

Many bodies around the world make their decisions through voting systems in which voters have several options and the collective result also has several options. Many of these voting systems are anonymous, i.e., all voters have an identical role in voting. Anonymous simple voting games, a binary vote for voters and a binary collective decision, can be represented by an easy weighted game, i.e., by means of a quota and an identical weight for the voters. Widely used voting systems of (...) this type are the majority and the unanimity decision rules. In this article, we analyze the case in which voters have two or more voting options and the collective result of the vote has also two or more options. We prove that anonymity implies being representable through a weighted game if and only if the voting options for voters are binary. As a consequence of this result, several significant enumerations are obtained. (shrink)

Le travail que Josep Monserrat Molas nous présente ici s’intitule Estranys, Setciències i Pentatletes. Ces trois mots cherchent à désigner des figures diverses sous lesquelles la philosophie peut se présenter au sein de la polis : soit des figures apparentes de la philosophie, soit quelques revêtements sous lesquels certains hommes se font passer pour ce qu’ils ne sont pas, soit enfin un trait fondamental du philosophe lui-même qui renverrait donc à la situation essen­tielle de toute philosop...

The work on set theory made by A. Tarski in the years 1924-1950 is very interesting, but little know.We develope partial questions in set theory in the moment that A. Tarski intervenes and his contributionsand also influences.The principals aims in this development are:1. The axiom of choice [A.C.] and his equivalents;2. the general continuum hypothesis [G.C.H.] and the A.C.;3. the dual trichotomy principle;4. the inaccessible cardinals and his relation with the A.C. and the G.C.H.;5. the notion of finite set and (...) his relation with the A.C and the G.C.H.;6. the almost disjoint set and their relation with the G.C.H.;and finally,7. the results in Berkeley.

La Misericordia de Dios lo abarca todo. Los atributos de Dios referidos a su Misericordia y Munificencia vienen reflejados en los nombres Ar-Rahman y Ar-Rahim. El primero es la cualidad exclusiva de Dios y se refiere a las gracias sobrenaturales y el segundo a las gracias naturales. En cuanto al siervo del Misericordioso. Abd Ar-Rahman, resume este nombre y es una gracia para todo el mundo en general. Abd Ar-Rahim, el siervo del Generoso, ejemplifica a la persona piadosa que practica (...) la compasión pero sobre todo con aquellos en los que Dios se complace.The Mercy of God includes all His creatíon. The Divine Qualities refered to the Compassionate and the Merciful are reflected in the names Ar-Rahman and Ar-Rahim. The first one is an exclusiva quality of God and it is refereá to the supernatural Grace and the second one to the natural Grace. As for the servant of the Compassionate epitomises this name and is a mercy to all the world in general. 'Abd Ar-Rahim, the servant of the Merciful exemplifies the pious that bestows his mercy particularly upon those with whom God is pleased. (shrink)

The moral pedagogy in the fairy tales is simple but powerful. It is concentrated in the lesson -according to the message of Aristotle- about the finalism sense of action: it makes the child understand that the human answer is an action with sense. Everything in the fairy tale leads to this perspective. Moreover, it exemplifies MacIntyre's opinion which says that current people tend to be proto-aristotelian and to understand their own life and the other's in narrative terms.

The topos of jews’ blindness, recurrent in adversos iudaeos literature, embodies in the image of blindfold Synagoga in medieval visual arts. The first part of this paper focuses on its integration in different contexts of medieval Spanish art. Diferent, but not less interesting, is the way caecitatis iudeorum is illustrated in some illuminated manuscripts of Breviari d’Amor by Matfre Ermengaud and Fortalitium Fidei by Alonso de Espina, also subject of study throughout these pages.

A previous work by Friedman et al. (Theory and Decision, 61:305–318, 2006) introduces the concept of a hierarchy of a simple voting game and characterizes which hierarchies, induced by the desirability relation, are achievable in linear games. In this paper, we consider the problem of determining all hierarchies, conserving the ordinal equivalence between the Shapley–Shubik and the Penrose–Banzhaf–Coleman power indices, achievable in simple games. It is proved that only four hierarchies are non-achievable in simple games. Moreover, it is also proved (...) that all achievable hierarchies are already obtainable in the class of weakly linear games. Our results prove that given an arbitrary complete pre-ordering defined on a finite set with more than five elements, it is possible to construct a simple game such that the pre-ordering induced by the Shapley–Shubik and the Penrose–Banzhaf–Coleman power indices coincides with the given pre-ordering.
