    (1 other version)Sets, classes and the propositional calculus.E. Lopez-Escobar - 2005 - Manuscrito 28 (2):417-448.
    The propositional calculus AoC, “Algebra of Classes”,and the extended propositional calculus EAC, “Extended Algebra ofClasses” are introduced in this paper. They are extensions, by additionalpropositional functions which are not invariant under the biconditional,of the corresponding classical propositional systems. Theirorigin lies in an analysis, motivated by Cantor’s concept of the cardinalnumbers, of A. P. Morse’s impredicative, polysynthetic set theory.

    Remarks on the church-Rosser property.E. G. K. López-Escobar - 1990 - Journal of Symbolic Logic 55 (1):106-112.
    A reduction algebra is defined as a set with a collection of partial unary functions (called reduction operators). Motivated by the lambda calculus, the Church-Rosser property is defined for a reduction algebra and a characterization is given for those reduction algebras satisfying CRP and having a measure respecting the reductions. The characterization is used to give (with 20/20 hindsight) a more direct proof of the strong normalization theorem for the impredicative second order intuitionistic propositional calculus.

    The Logic of Classes.E. G. K. Lopez-Escobar - 2007 - Logic Journal of the IGPL 15 (5-6):689-706.
    An extension of the Quantified Propositional Calculus1 obtained by the addition of two binary propositional functions is put forward as an inheritor of E. Schröder's “Algebra der Logik”. The formal system is itself not new, in fact it forms part of A. P. Morse's “A Theory of Sets”; although the latter is considered as a first-order system. Since the additional propositional functions are not invariant under the logical biconditional, this system–and many others naturally obtained from it–give us a collection of (...)

    Chateaubriand on propositional logic.E. López-Escobar - 2008 - Manuscrito 31 (1):103-113.
    In Logical Forms Part II, Chateaubriand begins the Chapter on “Propositional Logic” by considering the reading of the ‘conditional’ by ‘implies’; in fact he states that:There is a confusion, as a matter of fact, and it runs deep, but it is a confusion in propositional logic itself, and the mathematician’s reading is a rather sensible one.After a careful, erudite analysis of various philosophical viewpoints of logic, Chateaubriand comes to the conclusion that:Pure propositional logic, as just characterized, belongs to ontological logic, (...)

    Propositional logic: response to Ken López-Escobar.O. Chateaubriand - 2008 - Manuscrito 31 (1):115-120.
    Ken López-Escobar questions the timeless status of various entities—propositions, numbers, etc.—as well as my characterization of pure propositional logic as an ontological theory. In my response I argue that my characterization of propositional logic does not depend on timeless propositions, or on other abstract truth bearers, but is a characterization in terms of truth relations between any truth bearers. I also discuss his views on numbers as cultural constructs, as well as his use of quantification in propositional logic.Ken (...)

    Sobre el relativismo ético de Gilbert Harman.E. López Castellón - 1996 - Anales Del Seminario de Historia de la Filosofía 13 (S1):209.
    La cuestión práctica más importante del relativismo ético es sin duda la legitimidad de las valoraciones morales respecto a sociedades con sistemas morales diferentes del sistema de quien emite el juido de valor. El comunitarismo de la última década1 representado en esta cuestión por M. Walzer ha cuestionado precisamente dicha legitimidad y ha abogado por un «enfoque interno» que parta de los criterios de que toda forma de vida es «correcta» si sevive «de manera fiel a las concepciones compartidas por (...)

    En este artículo se estudian las razones que permiten establecer dos momentos en la filosofía kantiana de la historia, momentos que configuran una sutil evolución que, sin embargo, no contradice la intención esencial de la misma: El primero de ellos, anterior a 1790, se basa en un necesitarismo naturalista conjugado con la idea de la libertad como subsunción a la ley moral, lo cual dificulta la relación teoríapraxis, generando pesimismo histórico y, a la vez, no muy fundadas esperanzas en la (...)

    ‘Banality of evil’ was a concept introduced by Hannah Arendt in order to characterize a new form of wickedness embodied in people as Adolf Eichmann and others nazis criminals. Arendt thougt that this perverseness was very awey from the one of ‘radical evil’, a notion built by Kant and employed by Arendt herself in former works. This article seeks to point out that concepts of radical evil and banality of evil are closer than Arendt recognizes.
