Vivimos un tiempo de confusión, saturación, agitación, superficialidad, confrontación y polarización, sin rumbo, sin norte y necesitados de un sentido que no sabemos dónde encontrar. En los últimos siglos, hemos construido una sociedad saturada de bienes materiales y extremadamente financiarizada convirtiendo nuestra existencia en una carrera con poca conciencia de que vamos "hacia ninguna parte". El incremento de inquietudes y necesidades sociales, disfrazadas de consumo, nos lleva a buscar la inclusión, el acoplamiento y el reconocimiento social en una lucha de (...) la que resultan nuevos ganadores y muchos perdedores, insatisfechos o excluidos. Unos y otros, desde el éxito o desde el fracaso, con sus formas de interacción social, han dinamitado el contrato social que hasta ahora habíamos tenido por bueno, mientras seguimos pendientes de definir el nuevo contrato para una sociedad rica, abierta y global.

Argument evaluation, one of the central problems in argumentation theory, consists in studying what makes an argument a good one. This paper proposes a formal approach to argument evaluation from the perspective of justification logic. We adopt a multi-agent setting, accepting the intuitive idea that arguments are always evaluated by someone. Two general restrictions are imposed on our analysis: non-deductive arguments are left out and the goal of argument evaluation is fixed: supporting a given proposition. Methodologically, our approach uses several (...) existing tools borrowed from justification logic, awareness logic, doxastic logic and logics for belief dependence. We start by introducing a basic logic for argument evaluation, where a list of argumentative and doxastic notions can be expressed. Later on, we discuss how to capture the mentioned form of argument evaluation by defining a preference operator in the object language. The intuitive picture behind this definition is that, when assessing a couple of arguments, the agent puts them to a test consisting of several criteria. As a result of this process, a preference relation among the evaluated arguments is established by the agent. After showing that this operator suffers a special form of logical omniscience, called preferential omniscience, we discuss how to define an explicit version of it, more suitable to deal with non-ideal agents. The present work exploits the formal notion of awareness in order to model several informal phenomena: awareness of sentences, availability of arguments and communication between agents and external sources. We discuss several extensions of the basic logic and offer completeness and decidability results for all of them. (shrink)

According to the semantic view of computation, computations cannot be individuated without invoking semantic properties. A traditional argument for the semantic view is what we shall refer to as the argument from the cognitive science practice. In its general form, this argument rests on the idea that, since cognitive scientists describe computations (in explanations and theories) in semantic terms, computations are individuated semantically. Although commonly invoked in the computational literature, the argument from the cognitive science practice has never been discussed (...) in detail. In this paper, we shall provide a critical reconstruction of this argument and an extensive analysis of its prospects, taking into account some ways of defending it that have never been explored so far. We shall argue that explanatory considerations support at best a weak version of the argument from the cognitive science practice, according to which semantic properties concur with formal syntactic properties in individuating computations in cognitive science, but not a strong version, according to which computation individuation in cognitive science is semantic as opposed to formal syntactic.

The objective of this study is to provide insight into culinary systems. Each culture expresses its own identity through the way in which it transforms food into an elaborated cuisine. The phases of a cooking process start with the choice of ingredients, their preparation, their processing, how they are served, and how they are eaten. Each of these phases makes it possible to understand the semiotic and social behavior of a human group in the moment they choose to prepare and (...) eat a particular food. Therefore, this article contains a contrastive analysis of how Mexican, Texan, and Italian cuisines show how spicy and hot food is interpreted depending on the values that ​​are given to it in regards to being considered a dish, a spice or a vegetable. It bases its analysis on the mechanisms built around the meaning of chile in order to express cultural characteristics and differences. The recipes and their narrative processes, in addition to the use of color, allow the identification of parameters to describe the various cuisines through recipes books. (shrink)

This paper describes the first study of vasectomized men in Latin America; it is based on personal interviews with 172 men who had undergone the operation at least 3 months previously.

El artículo parte de la preocupación de saber cómo se está desarrollando la formación de investigadores en las universidades brasileñas. Una primera dificultad que se coloca es el predominio de un abordaje segmentado de la investigación científica. Eso lleva a un cuestionamiento sobre si particularmente las asignaturas de metodologías sirven para formar investigadores. Entre diversas dificultades, se incluyen desde aspectos epistemológicos hasta los impactos de las asignaturas metodológicas sobre la formación de los investigadores. Se cuestionan las estructuras de las disciplinas, (...) su relación con las metodologías, y las relaciones entre enseñanza metodológica y prácticas de investigación. Lo que está en juego es la formación de científicos sociales críticos en que se cuestionen diferentes separaciones extremamente rígidas de los procesos de formación.The present article focuses on the concern to know how the process of preparing investigators at Brazilian universities is being developed. One of the first difficulties being dealt with involves the predominant of segmented approach of the scientific investigation. This leads to the questioning of methodologies used to prepare these investigators. Among other several difficulties, the epistemological aspects up to the methodological ideas on the preparation of investigators are included. The structures of the subjects, their relation to the methodologies and the relations between methodological teaching and investigation practices are questioned. The preparation of critical social scientists in which extremely rigid different separations from the preparation processes is at stake here. (shrink)

A method for the recursive identification of physiological models of the cardiovascular baroreflex is proposed and applied to the time-varying analysis of vagal and sympathetic activities. The proposed method was evaluated with data from five newborn lambs, which were acquired during injection of vasodilator and vasoconstrictors and the results show a close match between experimental and simulated signals. The model-based estimation of vagal and sympathetic contributions were consistent with physiological knowledge and the obtained estimators of vagal and sympathetic activities were (...) compared to traditional markers associated with baroreflex sensitivity. High correlations were observed between traditional markers and model-based indices. (shrink)

LA JUVENTUD CONSUMIDA: REPRESENTACIONES DE LO JUVENIL EN EL DISCURSO PUBLICITARIO.

In this study I propose an epistemological discussion of multiple spatio-temporal scales in neuroscience. Are such scales merely convenient levels of description of structure and function, or do they correspond to irreducible levels of brain organization? What criteria should we employ in order to reduce one level to another, or to identify levels that are not reducible to others? Should we think of these criteria as based on empirical and/or theoretical reasons? Beginning with an empirical criterion – the necessity of (...) different experimental methodologies for the measurement of different phenomena in the same system – I summarize spatial and temporal scales currently used in neuroscience and discuss the possibility of a more general theoretical criterion. I conclude that multiscaling should be recognized as a central concept in the epistemology of neuroscience. (shrink)

According to Williamson’s epistemology of modality, we know metaphysical necessities by means of our knowledge of some specific counterfactualconditionals. In particular, Williamson’s idea is that we come to have knowledge of metaphysical necessities—which have the form □A—via our knowledge ofcounterfactual conditionals which have the form ~A□→┴. In this paper I claim that there are two different ways in which Williamson’s position can plausibly bearticulated, and that both ways lead to circularity.

The importance of the collective management of immaterial resources is a key variable in the valorisation of products in a post-industrial economy. The purpose of this paper is to analyse how, in post-industrial economies, it is possible to devise alternative forms of mediation between producers and consumers, such as organic farmers' markets, to curb the appropriation of rent by transnational and/or local business elites from the value created by immaterial resources. More specifically, we analyse those aspects of the collective management (...) of ethical values that, in the case of organic farmers' markets, can be a strategic source of competitive advantage for local producers. In this paper, the Ecomercado de Granada is studied as an example of mediation between production and consumption in a post-industrial economy. (shrink)

The Critique of Pure Reason—Kant’s First Critique—is one of the most studied texts in intellectual history, but as Alfredo Ferrarin points out in this radically original book, most of that study has focused only on very select parts. Likewise, Kant’s oeuvre as a whole has been compartmentalized, the three Critiques held in rigid isolation from one another. Working against the standard reading of Kant that such compartmentalization has produced, The Powers of Pure Reason explores forgotten parts of the First (...) Critique in order to find an exciting, new, and ultimately central set of concerns by which to read all of Kant’s works. Ferrarin blows the dust off of two egregiously overlooked sections of the First Critique—the Transcendental Dialectic and the Doctrine of Method. There he discovers what he argues is the Critique’s greatest achievement: a conception of the unity of reason and an exploration of the powers it has to reach beyond itself and legislate over the world. With this in mind, Ferrarin dismantles the common vision of Kant as a philosopher writing separately on epistemology, ethics, and aesthetics and natural teleology, showing that the three Critiques are united by this underlying theme: the autonomy and teleology of reason, its power and ends. The result is a refreshing new view of Kant, and of reason itself. (shrink)

This article aims to present the Coimbra Commentaries as a critical source of the Cartesian Meditations. The Cursus Conimbricensis played an important role in shaping the philosophical pedagogy of the seventeenth century, and many modern scholars were formed through the pages of these volumes. Although we do not know for sure whether the Coimbra Commentaries were used as textbooks in La Flèche, there are solid reasons for believing that, when Descartes refers to the possibility of divine deception in the first (...) meditation, he is using some examples taken from the Commentary on Physics written by Manuel de Góis.

Para entrever el futuro de la bioética lo primero que tenemos que pensar es la propia noción de futuro y nuestra relación práctica con el mismo. Expongo aquí a la crítica la idea de un futuro que esté ya de algún modo presente y a la vista. Es esta una idea que desposee al futuro de toda futureidad, una idea, por lo tanto, incoherente. Propongo, a cambio, pensar el futuro como tarea, como agenda, como aquello que no está y ha (...) de ser libremente hecho. En este sentido, resulta inútil tratar de vislumbrar o adivinar el futuro de la bioética, y en cambio es preciso proponernos como tarea la creación de la bioética futura. Vistas así las cosas, la función principal de la bioética no será ya la de deliberar y elegir entre las opciones que se nos presentan, sino la de crear nuevos cursos de acción que protejan y favorezcan mejor la vida en general y la vida humana en particular. Abogo, pues, en este texto, por una bioética de la creatividad y de la laboriosidad, superadora de la bioética de dilemas. (shrink)

Tenemos la sensación de que la tecnología nos resulta tan útil como peligrosa. Esta doble cara nos produce inquietud y desazón. De ahí derivan algunas prácticas que implican la renuncia total o parcial a ciertos modos tecnológicos. Dichas prácticas no siempre están dotadas de sentido y fundamentación suficientes. Constituyen, más bien, reacciones dispersas guiadas por sensaciones e intuiciones. En el otro polo, tenemos la obra de algunos pensadores que han reflexionado sobre la técnica. A partir de ahí, han enunciado valiosas (...) recomendaciones que permanecen, no obstante, en un plano abstracto. Nuestra hipótesis es que la noción de silencio tecnológico puede funcionar como un puente entre la especulación filosófica y la praxis efectiva, dando a la primera concreción y a la segunda lucidez. Para probarlo presentaremos, en primer lugar, la propia noción de silencio tecnológico (sección 1), para, a continuación, relatar algunas prácticas contemporáneas orientadas a la reducción de lo tecnológico (sección 2). En un tercer a paso expondremos las recomendaciones de Heidegger y Kierkegaard sobre lo técnico (sección 3). Veremos, acto seguido, en qué sentido el silencio tecnológico puede ejercer aquí de puente entre filosofía y praxis (sección 4). Recogeremos, por último, lo obtenido en un resumen conclusivo (sección 5). (shrink)

This paper proposes to determine and identify the origin of the gens Valgia from Arpinum. It is possible that the Valgii, by taking advantage of the political success of Gaius Marius, like other Arpinum families, already succeeded in obtaining the senatorial rank towards the end of the 2nd and the beginning of the 1st century BC. Later, thanks to Sulla's and Caesar's reforms, who sought allies among the powerful local gentes, the Valgii could consolidate their presence in Rome, until reaching (...) the consulate in 12 BC.

Este artigo está dividido em duas partes. Começo por oferecer algumas informações de fundo sobre as discussões e os debates que tiveram lugar na Europa no final da Idade Média e no início dos tempos modernos e que envolveram autoridades políticas e eclesiásticas. Não pretendo ser exaustivo nesta apresentação. Procuro apenas sugerir o contexto mais amplo das disputas entre o poder dos monarcas europeus e o da Igreja Católica durante os séculos XV, XVI e o início do século XVII. Na (...) segundaparte, trato especificamente da obra de Alonso de la Vera Cruz e utilizo a primeira parte como pano de fundo sobre o qual se pode compreender o pensamento de Frei Alonso. Buscarei sobretudo enfatizar o papel desempenhado pela Política de Aristóteles na concepção de Alonso sobre o casamento na Nova Espanha. (shrink)

In previous works, we presented a modification of the usual possible world semantics by introducing an independent temporal structure in each world and using accessibility functions to represent the relation among them. Different properties ofthe accessibility functions have been considered and axiomatic systems which define these properties have been given. Only a few ofthese systems have been proved tobe complete. The aim ofthis paper is to make a progress in the study ofcompleteness for functional systems. For this end, we use (...) indexes as names for temporal flows and give new proofs of completeness. Specifically, we focus our attention on the system which defines injectivity, because the system which defines this property without using indexes was proved to be incomplete in previous works. The only system considered which remains incomplete is the one which defines surjectivity, even ifwe consider a sequence ofnatural extensions ofthe previous one. (shrink)

Introduzione Il problema filosofico centrale di Lexical Competence (Marconi 1997 — i riferimenti che faremo sono relativi all’edizione italiana apparsa due anni dopo) è che cosa distingue la comprensione del linguaggio da parte di un agente umano da quella che potrebbe essere attribuita a un sistema artificiale. Nel rispondere a questa domanda Marconi (d’ora in poi, M.) offre una teoria della conoscenza del significato, descrive cioè in che cosa consiste conoscere il significato delle parole...

: According to Crane intentionality is nothing less than the mark of the mental. Nonetheless, there are many issues raised by this concept, beginning with the problem of non-existent relata. In this comment-article I discuss the concept of intentionality in its generality, trying to state its ontological status and to assess its explanatory dispensability. In particular, I focus on the argument, addressed by Crane, whereby Wittgenstein eliminates intentionality, characterizing it as a grammatical fiction, a pseudo-entity created by the grammar of (...) the language of mental states ascriptions. I will argue that: although Crane’s specific argument against Wittgenstein is not conclusive, Wittgenstein’s linguistic strategy does not work; and yet we should not be committed to a robust realist account of intentionality. Keywords : Intentionality; Ludwig Wittgenstein; Mark of the Mental; Ontological Commitment; Realism/Anti-realism. L’intenzionalità è sufficientemente reale? Riassunto : Il concetto di intenzionalità è l’autentico cuore della filosofia di Tim Crane, secondo il quale l’intenzionalità è niente di meno che il marchio del mentale. Nondimeno, vi sono diversi noti problemi sollevati da questo concetto. In questo articolo-commento discuto il concetto di intenzionalità nelle sue linee generali cercando, da un lato, di determinarne lo statuto ontologico e, dall’altro, di valutarne la dispensabilità esplicativa. Mi concentro in particolare sull’argomento, discusso da Crane, con cui Wittgenstein elimina l’intenzionalità, caratterizzandola come una finzione grammaticale, una pseudo-entità creata della grammatica del linguaggio con cui attribuiamo stati mentali. Sosterrò che: sebbene lo specifico argomento di Crane non sia conclusivo, la strategia “linguistica” di Wittgenstein non funziona e tuttavia non dovremmo indulgere a una concezione realista “robusta” dell’intenzionalità. Parole chiave : Intentionalità; Ludwig Wittgenstein; Marchio del mentale; Impegno ontologico; Realismo/Anti-realismo. (shrink)

O presente artigo divide-se em duas partes. Na primeira, analisa-se a noção de um ser mental como sujeito da lógica. O principal objetivo dessa parte é fornecer algumas notas históricas sobre a origem e a importância de uma noção bastante difundida nos séculos XIII e XIV. A segunda parte concentra-se na filosofia de Avicena e procura mostrar como esse autor opõe-se à existência de um ser mental como sujeito da lógica.

Philosophers of perception frequently assume that we see actual states of affairs, or facts. Call this claim factualism. In his book, William Fish suggests that factualism is supported by phenomenological observation as well as by experimental studies on multiple object tracking and dynamic feature-object integration. In this paper, I examine the alleged evidence for factualism, focusing mainly on object detection and tracking. I argue that there is no scientific evidence for factualism. This conclusion has implications for studies on the phenomenology (...) and epistemology of visual perception. (shrink)

The modern world was in part born as a reaction against Aristotelianism. However, the image of Aristotle to which modern philosophers reacted was partial, to say the least. Paradoxical though it may seem, today, more than twenty-three centuries on, we may now be in the most advantageous position for understanding the Stagirite's philosophy and applying it to contemporary problems. The present book contributes to the forming of an idea of Post-modern reason inspired by a constellation of Aristotelian concepts, such as (...) prudence (phronesis), practical truth (aletheia praktike), science in act (episteme en energeiai), metaphor (metaphora), similarity (homoiosis) and the imitation-creation pair (mimesis-poiesis). They all form an interconnected network and together they make up an idea of reason that may prove suitable for the present. These concepts offer the most promising basis for undertaking a series of urgent reconciliations: of facts and values, of means and ends, of theoretical and practical reason, of intelligence and emotion. Aristotle's notions could help solve many dualisms of modern times. He offers a third way between identity and difference in ontology and politics, between algorithm and anarchism in methodology, between naïve realism and plain relativism in epistemology, between equivocity and univocity in language, between Enlightenment and Romanticism in culture... On the way, this shift facilitates the relationships between science, arts and ethics - the three parts of the sphere of culture which Modernity had separated - as well as the integration of the sphere of culture itself with the world of life.
