The notion of monadic three-valued ukasiewicz algebras was introduced by L. Monteiro ([12], [14]) as a generalization of monadic Boolean algebras. A. Monteiro ([9], [10]) and later L. Monteiro and L. Gonzalez Coppola [17] obtained a method for the construction of a three-valued ukasiewicz algebra from a monadic Boolea algebra. In this note we give the construction of a monadic three-valued ukasiewicz algebra from a Boolean algebra B where we have defined two quantification operations and * such that *x=*x (where (...) *x=-*-x). In this case we shall say that and * commutes. If B is finite and is an existential quantifier over B, we shall show how to obtain all the existential quantifiers * which commute with .Taking into account R. Mayet [3] we also construct a monadic three-valued ukasiewicz algebra from a monadic Boolean algebra B and a monadic ideal I of B. (shrink)

En el presente trabajo de homenaje al Profesor Julio De Zan, me concentro en su crítica al realismo moral. En su libro, La ética, los derechos y la justicia, Julio De Zan niega que existan en el ámbito moral propiedades naturales o metafísicas. Para comprender su crítica, propongo una reconstrucción conceptual de los presupuestos filosóficos que existen para su rechazo del realismo moral. Con este propósito, mi propuesta de reconstrucción conceptual consiste en complementar la ética del discurso defendida (...) por Julio De Zan, relacionando su propuesta con dos complementos filosóficos: por un lado, con el rechazo hacia el realismo moral realizado por Ronald Dworkin en su libro Justicia para erizos; por otro lado, con el rechazo hacia el realismo moral dirigido por Christine Korsgaard en su libro Las Fuentes de la Normatividad. Aunque los tres filósofos mantienen diferencias relevantes, mantienen también un rechazo al realismo moral basado en ciertos parecidos de familia. (shrink)

El autor hace una lectura de la literatura de Cortázar desde la pregunta sobre la proximidad, y señala que la dificultad en delimitar con precisión el lugar de la subjetividad le viene a Cortázar de la desarticulación categorial provista por la herencia cartesiana y del contacto esporádico con el último Heidegger. Afirma que la literatura de Cortázar continúa el derrotero abierto por la modernidad tardía en tanto que los cuestionamientos alcanzan inexorablemente al sujeto.

El tema principal es la concepción de la política en Julio Irazusta (1899-1982), pensador adherido al nacionalismo argentino. Pero la obra tiene un sentido integral, y trata aspectos de biografía intelectual y analiza las influencias de autores como Maurras, Burke, de Maistre y Croce, que habrían obrado sobre el pensamiento de Irazusta"--Handbook of Latin American Studies, v. 58.

One version of the Julius Caesar problem arises when we demand assurance that expressions drawn from different theories or stretches of discourse refer to different things. The counter‐Caesar problem arises when assurance is demanded that expressions drawn from different theories . refer to the same thing. The Julio César problem generalises from the counter‐Caesar problem. It arises when we seek reassurance that expressions drawn from different languages refer to the same kind of things . If the Julio César (...) problem is not resolved then the Fregean account of numbers as objects is cast into doubt, the notion of number left relative to a language. Wright introduced this problem by asking whether there can be such a thing as ‘International Platonism’. After rejecting Hale's attempt to resolve it I argue that the threat posed by the Julio César problem diminishes – even though it cannot be made to logically disappear – once it is recognised that the radical interpretation of an unfamiliar language is inevitably holistic, the evidence available invariably defeasible and consequently Cartesian certainty about the significance of the utterances of a foreign tongue neither to be sought after nor attained.

In the tradition of philosophy in Argentina, Hegel has meant to this day a source of important views on the nature of society and history. The Phenomenology of the spirit turns out to be a provocation of the thought that finds in Julio De Zan a privileged interpreter. From his academic beginnings as a professor and researcher, he was initially interested in this work. In the context of this dossier dedicated to “Hegel’s philosophy in Argentina”, we propose an analysis (...) of two articles by Julio De Zan published at different times: “Sense and validity of the Phenomenology of the spirit” and “Experience and praxis. Method questions in Hegel’s Phenomenology of the Spirit”. (shrink)

This article discusses some continuous limit cases of Susan Haack’s crossword puzzle metaphor for the coherent development and foundation of science. The main objective of this discussion is to build a bridge between Haack’s foundherentism and the epistemological framework of objective cognitive constructivism, including its key metaphor of objects as tokens for eigen-solutions. The historical development of chemical affinity tables is used to illustrate our arguments.

Resumen La educación superior se ha constituido en un objeto de creciente interés en la literatura especializada. A pesar de lo anterior, la mayor parte de la investigación disponible se concentra en estudios de corte descriptivo y evaluativo, sin conectar sus desarrollos con las reflexiones de la teoría sociológica. El presente ensayo identifica las principales posibilidades teóricas y epistemológicas de la teoría de sistemas sociales para el análisis de la educación superior, examinando los rendimientos de la noción de diferenciación de (...) planos de formación sistémica (interacción, organización y sociedad) y la idea de diferenciación de sistemas parciales especializados. Abstract Higher education has become an object of growing interest in the specialized literature. Despite this, most of the available research concentrates on descriptive and evaluative studies, without connecting its developments with the reflections of general sociological theory. This essay identifies the main theoretical and epistemological possibilities of social systems theory for the analysis of higher education, examining the uses of the notion of differentiation of systemic formation planes (interaction, organization, and society) and the idea of differentiation of specialized partial systems.

Although logical consistency is desirable in scientific research, standard statistical hypothesis tests are typically logically inconsistent. To address this issue, previous work introduced agnostic hypothesis tests and proved that they can be logically consistent while retaining statistical optimality properties. This article characterizes the credal modalities in agnostic hypothesis tests and uses the hexagon of oppositions to explain the logical relations between these modalities. Geometric solids that are composed of hexagons of oppositions illustrate the conditions for these modalities to be logically (...) consistent. Prisms composed of hexagons of oppositions show how the credal modalities obtained from two agnostic tests vary according to their threshold values. Nested hexagons of oppositions summarize logical relations between the credal modalities in these tests and prove new relations. (shrink)

Conceptual congruency effects are biases induced by an irrelevant conceptual dimension of a task (e.g., location in vertical space) on the processing of another, relevant dimension (e.g., judging words’ emotional evaluation). Such effects are a central empirical pillar for recent views about how the mind/brain represents concepts. In the present paper, we show how attentional cueing (both exogenous and endogenous) to each conceptual dimension succeeds in modifying both the manifestation and the symmetry of the effect. The theoretical implications of this (...) finding are discussed. (shrink)

In this article, we discuss some issues concerning magical thinking—forms of thought and association mechanisms characteristic of early stages of mental development. We also examine good reasons for having an ambivalent attitude concerning the later permanence in life of these archaic forms of association, and the coexistence of such intuitive but informal thinking with logical and rigorous reasoning. At the one hand, magical thinking seems to serve the creative mind, working as a natural vehicle for new ideas and innovative insights, (...) and giving form to heuristic arguments. At the other hand, it is inherently difficult to control, lacking effective mechanisms needed for rigorous manipulation. Our discussion is illustrated with many examples from the Hebrew Bible, and some final examples from modern science. (shrink)

Este artigo consiste em um diálogo com textos de Jürgen Habermas e Richard Rorty referentes ao tema da religião e seu lugar na sociedade contemporânea. Em vista do tom dialogal, as citações desses autores são relativamente numerosas, a fim de que as suas vozes sobressaiam no texto. O objetivo do diálogo é extrair pistas para a construção de uma filosofia da religião em tom pós-metafísico, ou não fundacional. Não é um texto exaustivo, mas sugestivo. Não se propõe a tecer críticas (...) ao sistema de ideias dos autores com quem dialoga, mas aproveitar criticamente algumas de suas ideias para a definição de possíveis rumos para uma filosofia da religião pós-metafísica. Os termos pós-metafísico e não fundacional são usados aqui de modo intercambiável e não se referem a um tipo de filosofia antimetafísica, mas sim, a uma filosofia para a qual os temas da metafísica não assumem papel de explicação fundacional da realidade como um todo. Palavras-chave : Filosofia pós-metafísica; Habermas; Rorty; Religião.This essay is a dialogue with Jürgen Habermas’s and Richard Rorty’s texts on the theme of religion and its place in contemporary society. Given the conversational tone, the number of quotations from those authors is relatively large, so that their voices can speak up in the text. The goal of that dialogue is the formulation of clues to the elaboration of a post-metaphysical or non-foundational philosophy of religion. The essay is not exhaustive, but suggestive. It does not mean to criticize Habermas’s and Rorty’s systems of thought, but to appropriate critically some of their ideas as guidelines to a post-metaphysical philosophy of religion. The terms ‘post-metaphysical’ and ‘non-foundational’ are interchangeable here and do not refer to an anti-metaphysical philosophy. They try to express a kind of philosophy in which metaphysical themes do not play a role of foundational explanation of reality as a whole. Key words : Post-metaphysical philosophy; Habermas; Rorty; Religion. (shrink)

X. Zubiri, uno de los pensadores espanoles mas sobresalientes en el presente siglo, nos ha hecho ver que el mal se entiende como condicion de la realidad en respectividad ante el hombre, o sea, en la interaccion del hombre con las cosas reales o consigo mismo en cuanto realidad. En este sentido, el mal se entiende desde la realidad condicionada. Como se entiende que el mal surja desde la realidad? Cual es la consistencia del mal en cuanto condicion? En que (...) supera Zubiri la vision del mal como privacion del bien? El presente estudio pretende dar respuesta a tales cuestiones, considerando el planteamiento del mal segun Zubiri desde el contexto de su pensamiento filosofico.

This article has as its theme the democracy as fundamentalism, or the democratic fundamentalism. Its main objective is the recognition that the thinking about democracy can itself be fundamentalist, implying that not only religious fundamentalisms are a threat to contemporary democracy. Its method and object are the interpretation of texts by two contemporary philosophers who do not usually talk to each other, the Italian Gianni Vattimo and the French Jean-Luc Nancy. The essay's thesis is the affirmation of democratic thinking as (...) a form of fundamentalism, insofar as it fulfills certain conditions established by the two thinkers analyzed. These conditions are, in the language of the aforementioned philosophers, the framing of democracy under the so-called strong thought, or its subsumption to a metaphysical way of thought, so that it becomes incapable of self-criticism and its necessary reinvention. Thus, it is expected to contribute to the construction of a self-critical vision of democracy through dialogue with aspects of thought little known of important philosophers and also through the dialogue between philosophy and theology as emancipatory ways of knowing.
