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.

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.

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.

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)

Łukasiewicz’s infinite-valued logic is commonly defined as the set of formulas that take the value 1 under all evaluations in the Łukasiewicz algebra on the unit real interval. In the literature a deductive system axiomatized in a Hilbert style was associated to it, and was later shown to be semantically defined from Łukasiewicz algebra by using a “truth-preserving” scheme. This deductive system is algebraizable, non-selfextensional and does not satisfy the deduction theorem. In addition, there exists no Gentzen calculus fully adequate (...) for it. Another presentation of the same deductive system can be obtained from a substructural Gentzen calculus. In this paper we use the framework of abstract algebraic logic to study a different deductive system which uses the aforementioned algebra under a scheme of “preservation of degrees of truth”. We characterize the resulting deductive system in a natural way by using the lattice filters of Wajsberg algebras, and also by using a structural Gentzen calculus, which is shown to be fully adequate for it. This logic is an interesting example for the general theory: it is selfextensional, non-protoalgebraic, and satisfies a “graded” deduction theorem. Moreover, the Gentzen system is algebraizable. The first deductive system mentioned turns out to be the extension of the second by the rule of Modus Ponens. (shrink)

In this article we consider certain elements of the normative theory of Jürgen Habermas in the light of the proposals of Bruce Ackerman, with a view to strengthening a concept of deliberative democracy applied to the legitimation of juridical rules. We do not construct a hierarchy of the two positions, but seek to bring together certain elements to achieve a common project. As the starting point for examining the work of the two authors, we take the scheme proposed by Habermas (...) in Faktizität und Geltung. In this connection, through the work of Ackerman, we intend to fill in some of the gaps that Habermas appears to have left in the theory of radical democracy applied to the law. The work of Ackerman can make a significant contribution to deliberative democracy, to the discourse principle that Habermas defines, and to the contractualist theories from a liberal perspective. The study of these contributions makes possible a critical judgment that enables the legitimation of juridical rules carried out by Habermas to acquire greater practicity. In examining the epistemological status of juridical science and law, we attempt to determine the weight and the performance of normative democracy. In Tarr's view, it is a matter for philosophers to examine direct democracy and its desirability. (shrink)

Guizot aprendió el oficio de historiador preparando con su esposa,Pauline de Meulan, una edición crítica en francés de _Decline and Fall_ de Gibbon. Las personalidades históricas de Gibbon y Guizot fueron muy distintas. También sus respectivos “estilos de historia”. Pero en las obras de Guizot, en especial en su _Historia de la civilización en Europa_, es reconocible el legado de Gibbon. Así, en la eliminación de la barrera entre historia civil y historia religiosa, en la amplitud temática, en la ambición (...) cronológica y en una idea de Europa concebida como algo más que la suma de sus partes. Asimismo en la adopción de la misma palabra _civilización_ y en el hecho de que la interpretación guizotiana de la historia europea hunda sus raíces en tres factores presentes en Gibbon: lo que sobrevivió de las instituciones romanas, el impacto del cristianismo y el aporte germánico.
