    Libertad de vivir
    Isegoría 27 131-149. 2002.
    Hay dos tipos de bienes y derechos: de bienestar y de libertad. Los primeros, irrenunciables, acarrean deberes positivos, de dar o hacer. Los derechos de libertad, en cambio, sólo imponen a otros deberes negativos, dejando a su titular libre para ejercerlos o no según quiera. Sostenemos que el derecho a la vida es un derecho de libertad. De ahí se sigue que no es obligatorio aceptar el don de la vida salvo cuando el ordenamiento permite a los progenitores presumir el futuro consentimiento retroa…Read more

    De la logique combinatoire des ‘Generales Inquisitiones’ aux calculs combinatoires contemporains
    Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 6 (1-2): 129-159. 1991.
    In his 1686 essay GI Leibniz undertook to reduce sentences to noun-phrases, truth to being. Such a reduction arose from his equating proof with conceptual analysis. Within limits Leibniz’s logical calculus provides a reasonable way of surmounting the dichotomy, thus allowing a reduction of hypothetical to categorical statements. However it yields the disastrous result that, whenever A is possible and so is B, there can be an entity being both A and B. Yet, Leibniz was in the GI the forerunner of…Read more

    This paper develops several insights put forward in the book Republican Studies. It goes into the difference between republicanism as a concept pertaining to legal theory, i.e. a system free from dynastic power, and the political-philosophy trend which currently goes by the same name, also known as `civicism', hinging upon the notion of freedom as non-domination. As against such a view, the value of a classical notion of liberty is maintained. Further grounds to choose a republic rather than a m…Read more

    Es tarea de todos aplicar una ley, o sea realizar y ejecutar aquellos actos jurídicos y hechos prácticos que desembocan en su cumplimiento o lo constituyen. Se aplica una norma de carácter implicativo cuando, ante la existencia de un supuesto de hecho previsto en ella, se concluye la obligación contenida en su consecuencia jurídica, actuándose de conformidad con ello. Eso es incompatible con la separación de lo normativo y lo fáctico, propia del normativismo de Kelsen. Y es que hay situaciones j…Read more

    While lawers and philosophers of law show the difference between matters of fact and normative situations, this paper proves that the difference is not crisp, since, in accordance with usual international private law, foreign juridical norms are, in principle, considered facts, but only up to a certain degree.

    ¿Están comprendidos los extranjeros en el ámbito de aplicación de los derechos y deberes fundamentales estipulados por las constituciones modernas? Lamentablemente, no. Ha habido, a lo largo de la historia, progresos y retrocesos en la conciencia jurídica de los derechos migratorios. Hoy tienden a establecerse cláusulas de libre circulación en los espacios de integración económica, al paso que, de manera general , viene prohibida la inmigración del sur al norte. Esa orientación actual es injusta…Read more

    Un enfoque no-clásico de varias antinomias deónticas (review)
    Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 3 (1-3): 67-94. 1987.
    Three (apparent ) deontic antinomies are discussed: the paradoxes of the watchman and the praiser, as weIl as deontic dilemmas. A paraconsistent deontic logic, Ad, is put forward whose underlying 1st-order calculus is an infinite-valued tensorial logic. Several arguments are offered bearing out be existence of deontic contradictions, while two ways of dealing with conditional obligation paradoxes within the framework of Ad are canvassed. While the aggregation rule and the ought-implies-can princ…Read more

    There are two main approaches to a theory of rationality: the positive one and the negative one. The latter, which has gained increasing acceptance, is primarily concerned with rejecting what is irrational, which usually is equated with what is inconsistent. The positive approach has a quite different purpose, that of studying reasoning and, insofar as possible, enhancing the patterns or standards of our reasoning practice

    Phonemes are minimal segments within the spoken message whose presence is relevant for distinguishing one message from a different one with another meaning. Each phoneme underlies different phonetic realizations. What sets a phoneme from another is fuzzy cluster of the fuzzy features. Thus the study of phonemic structures is likely to have much to gain from a gradualistic approach. Through a gradualistic treatment synchronic phonology could tally with the diachronic study in a simpler way than i…Read more
