84Imperativos, preceptos y normasLogos. Anales Del Seminario de Metafísica [Universidad Complutense de Madrid, España] 39 111-142. 2006.The paper goes into the intricate logical relation between imperatives, precepts and norms. It shows that there need not be two senses of "ought", the one descriptive and the other prescriptive, since when the law-giver enacts a fresh statute he is hereby making a tru statement, whose truth is grounded on the statement itself.

Da Costa's paraconsistent systems of the series Cm (for finite m) (see [C1], [C2], and esp. [C3], pp. 237ff.) share important features with transitive logic, TL (which has been gone into in [P1] and [P2]), namely, they all coincide in that: (c1) they possess a strong negation, `¬', a conditional, `⊃', a conjunction, `∧', and a disjunction, `∨', with respect to which they are conservative extensions of CL or Classical Logic; (c2) they possess a non strong negation, `N' (notations are different fo…Read more

8La igualdad intelectual como principio de lo múltiple en el pensamiento del CusanoAnuario Filosófico 28 (3): 711-736. 1995.Within Nicholas de Cusa's philosophical approach, there is bound to be a level of unity lower than the one pertaining to God as such but higher than those of common creatures. The intermediate level belongs to the Intellect and is characterized by an affirmative coincidence of opposites hinging around universal equality. Such intellectual equality among all things, as they are in the Intellect, constitutes the root of number and multiplicity.

9There 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

1419Graham Priest's «Dialetheism» -- Is It Althogether True?Sorites 7 28-56. 1996.Graham Priest's book In Contradiction is a bold defense of the existence of true contradictions. Although Priest's case is impressive, and many of his arguments are correct, his approach is not the only one allowing for true contradictions. As against Priest's, there is at least one contradictorialist approach which establishes a link between true contradictions and degrees of truth. All in all, such an alternative is more conservative, closer to mainstream analytical philosophy. The two approac…Read more

56Un enfoque no-clásico de varias antinomias deónticasTheoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 3 (1-2): 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

19The paper examines Beuchot's approach and agrees that there are many coincidences between medieval Aristotelianism and analytical philosophy. Both pursue philosophical inquiry in an argumentative manner. Nowadays analytical philosophy also tends to recognize as genuine such traditional metaphysical problems as were debated by the Scholastics. The paper's only criticism at Beuchot's views concerns analogy and reduplicative as-clauses. It argues that on that issue the cleavage between medieval and…Read more

16Libertad de vivirIsegoría 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
