This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

Os visigodos, que professavam o arianismodesde antes de seu estabelecimento na PenínsulaIbérica, converteram-se ao Catolicismo deNicéia em fins do século VI, por ocasião do mConcilio de Toledo, realizado em 589. Os vinculesentre a Igreja e o Estado, a partir deste momento,tomaram-se estreitos.A teoria política que sustentou ideologicamente oReino Visigodo, deste momento até a chegadados muçulmanos, encontra-se, fundamentalmente,nas obras de Isidoro de Sevilha e nas Atas dosConcílios de Toledo. Tais documentos serão objetode nosso estudo, que visa a reconstrução daslinhas mestras (...) desta teoria política. (shrink)

Many times we have discussed about the appropriateness of situating to Vygotski in the Olympus of psychology. Even today, 80 years later, his theories continue creating as many supporters, defenders of his originality, as effusive critics who accuse the methodological shortcomings of his work. In our view, one of the shortcomings that have accused more his work is the lack of a solid theoretical foundation that endows meaning with the available host of data and results. Therefore, the objective of this (...) article is to show a feasible solution that would be to approach, sometimes encounter with certain phenomenological propositions, for that matter, from the phenomenological studies of perception and its attention to the weight of cultural predicates, where the language is the main element and, at the same time, the meeting point with Vygotski which will help strengthen the foundations of its proposal.

Plato's political thought gave rise to a number of concepts and issues - such as the idea of a normative theory, the philosophical foundation of politics, the philosopher-kings, the standard of utopian theory - which have played a significant role on Western political and philosophical thought. -/- This volume aspires to bring out Plato's concept of efficacy in a normative theory. -/- By efficacy, the author means the way in which the theory conceives of its practical realization. If in the (...) Republic this issue is particularly problematic, in the Laws, instead, the claim of realizability becomes the main concern. -/- By defining the concept of efficacy and going through the main works of Plato, this conceptual and textual analysis aims to shed a new light on Plato's political thought, which is neither a utopia, nor a short term political program, but the first normative theory encompassing a theory of efficacy.

El presente trabajo replantea la clásica dicotomía de teoría y praxis situada en el centro de la disputa entre el movimiento estudiantil alemán de protesta y Theodor W. Adorno. En un primer momento, se presenta una reconstrucción histórica enfocada en algunos episodios que caracterizan el clima de finales de la década del sesenta alemana, resaltando la figura mediadora del cineasta y escritor alemán Alexander Kluge. A partir de allí, se iluminan los cruces y las asociaciones antes que las posiciones dicotómicas (...) frente al hacer/no hacer: teoría, política y arte se plantean como mediaciones diferentes e interrelacionadas de la noción de crítica de las tres las posiciones.

O presente artigo objetiva discutir a interpretação da filosofia de Nietzsche empreendida por Hans Vaihinger na obra Philosophie des Als Ob. De acordo com Vaihinger, ao longo de sua obra Nietzsche desenvolve uma “teoria da aparência valor das ficções frente à vida prática, na trilha deixada por Kant e Lange. Em virtude disso, a filosofia de Nietzsche pode ser considerada como o esboço da metafísica do “como se”, postura ficcionalista e pragmática desenvolvida por Vaihinger.

This article studies the "Theory of the Pur Object" in the Spanish philosopher Antonio Millán-Puelles, relating it to the Scholastics and to of Husserl and Hartmann.

The paper conceptualizes economic models as metaphors. It presents two different approaches to economic modeling. In the first one, economic models are treated as isolations which aim at representing the real world. In the second, they are conceptualized according to various philosophical approaches that are close to fictionalism. The aim of such modeling is to persuade and not to represent. Next, the author tries to escape the dichotomy between models as isolations and models as purely rhetorical devices by referring to (...) N. Cartwright’s understanding of economic models. The issue of their realism is also considered. The final conclusion states that models are very similar to metaphors. (shrink)

In the article we are trying to answer the question why people make mistakes in their reasoning. According to the theory proposed by P. N. Johnson-Laird, reasoning is a semantic process based on mental models. Reasoners build models of the situations described in premises and then check which conclusion holds in all the models. Unfortunately, our working memory has a limited processing capacity, and so we often fail to represent all possibilities necessary to draw a valid conclusion. The more models (...) we have to build, the higher the chance of making a mistake. Due to limitations of our working memory, we tend to represent in the models only what is true, but not what is false. One of the consequences of this fact is the occurrence of certain illusions: inferences that are compelling but invalid. The existence of such illusionary inferences have been corroborated by numerous experiments. (shrink)

El uso de los términos vagos por la comunidad lingüística competente delimita con precisión la extensión de dichos términos, fijando en qué casos se aplican definidamente, en cuáles se aplican no definidamente y en cuáles es indeterminado si se aplican. Esto produce dos órdenes de vaguedad, con lo que se bloquean los argumentos sorites. La vaguedad se basa en una indeterminación determinada en la aplicación de ciertos términos por parte de los hablantes nativos.

The article argues in favour of replacing Dewey’s notion of 'experience' in today's cognitive sciences with Mead’s notion of 'act.' Although Dewey's approach to cognition is an essential contribution to the pragmatist turn of cognitive science and his theory of organic relation is particularly useful for future developments in this field, his notion of 'experience' risks proving to be the weak link in the program of empirical implementation of such a turn. In a perspective that shows a clear empirical intent (...) such as that of the 4E programme, the concept of experience, as intentionally vague and smoky, with its strong metaphysical significance, does not seem to offer a useful operational criterion to exclude from evaluation aspects that should not be considered constitutive of the mental. Moreover, in its openness to the overall determination of the relationship between organism and environment, this notion does not contribute to the definition of the phases that characterize the relational dynamics itself. The essay proposes as a solution to these difficulties to turn the attention to Mead's notion of 'act.' Although Mead's act and Dewey's experience are undoubtedly similar concepts, as the result of elaborations often carried out jointly by the two authors, the act seems more suitable to describe in its different characteristics the ideo-sensori-motor process that characterizes the integrated approach in which perception and action are indissolubly linked. Mead's theory of the act is an epistemological tool particularly useful to the empirical program of the 4E, also offering an interesting contribution to the debate between radical representationalists and enactivists.

O presente artigo lança luz sobre as flutuações semânticas do termo “liberdade” na obra de Leonardo Bruni, buscando nuançar sua apreensão por parte da tradição anglófona de pensamento político conhecida como neorrepublicanismo. A partir da análise conceitual e estilística de diversas passagens centrais da obra do autor florentino, o artigo visa retornar aos usos e significados da palavra “liberdade” em Bruni, colocando a questão da relação entre um âmbito de utilização “teórica” e um âmbito de utilização histórica ou narrativa.

La conocida teoría de la intersubjetividad, desarrollada por Husserl en sus Meditaciones Cartesianas, ha sido objeto de innumerables críticas. La virtud de estas críticas es que son precisamente ellas las que han ofrecido la posibilidad de renovar la fenomenología como teoría social. Nuestro propósito es confrontar la Quinta meditación cartesiana con otros textos del corpus husserliano para proponer tres nuevas entradas críticas a su teoría de la intersubjetividad en relación a la cuestión del lenguaje, el mundo y la cultura, y (...) las insuficiencias que la Quinta meditación cartesiana encierra frente a esos presupuestos.
