In [8] it is proved that all the intermediate logics axiomatizable by formulas in one variable, except four of them, are not strongly complete. We considerably improve this result by showing that all the intermediate logics axiomatizable by formulas in one variable, except eight of them, are not strongly ω-complete. Thus, a definitive classification of such logics with respect to the notions of canonicity, strong completeness, ω-canonicity and strong ω-completeness is given.

Aristotle normally used historical notations to support his arguments. This is somewhat true for all the works of the corpus, but above all for Politics: the nature, objectives, and methodology of the investigations in this treatise present the strongest links with actual and concrete data, and therefore with historia. Obviously even the Aristotle of Politics is not a historian who wants to report known historiographical traditions; however, regardless of his intentions, there is no doubt that the work in question contains (...) precious ‘fragments’ of history which, in general, confirm or supplement our knowledge. There are, however, cases in which the Aristotelian exempla end up filling in the omissions and gaps of the available sources, such as the cursory reference to the nomos of the Aphytaians, which appears in the section of book 6 dedicated to the so-called agricultural democracy.

The field of numerical cognition provides a fairly clear picture of the processes through which we learn basic arithmetical facts. This scientific picture, however, is rarely taken as providing a response to a much‐debated philosophical question, namely, the question of how we obtain number knowledge, since numbers are usually thought to be abstract entities located outside of space and time. In this paper, I take the scientific evidence on how we learn arithmetic as providing a response to the philosophical question (...) of how we obtain number knowledge. I reject the view that numbers are abstract entities located outside of space and time and, alternatively, derive from the scientific evidence a novel account of the nature of numbers. In this account, numbers are reifications of the counting procedure and arithmetic statements are seen as describing the functioning of counting and calculation techniques. (shrink)

Aristóteles usó normalmente notaciones históricas para apoyar sus argumentos filosóficos. Esto es cierto para todas las obras del corpus, pero sobre todo para la Política: la naturaleza, los objetivos y la metodología de las investigaciones en este tratado presentan los vínculos más fuertes con datos reales y concretos, y por lo tanto con la historia. Evidentemente, el Aristóteles de la Política no es un historiador que quiera informar sobre tradiciones historiográficas conocidas; sin embargo, independientemente de sus intenciones, no hay duda (...) de que la obra en cuestión contiene preciosos ‘fragmentos’ de historia que, en general, confirman o complementan nuestro conocimiento. Hay, sin embargo, casos en los que los exempla aristotélicos acaban llenando las omisiones y lagunas de las fuentes disponibles, como la rápida y concisa referencia al nomos de los Aphytaioi, que aparece en la sección del libro 6 dedicada a la llamada democracia agrícola. Palabras-clave: Aristóteles, Política, historia, democracia agrícola, Aphytaioi. (shrink)

We extend to the predicate frame a previous characterization of the maximal intermediate propositional constructive logics. This provides a technique to get maximal intermediate predicate constructive logics starting from suitable sets of classically valid predicate formulae we call maximal nonstandard predicate constructive logics. As an example of this technique, we exhibit two maximal intermediate predicate constructive logics, yet leaving open the problem of stating whether the two logics are distinct. Further properties of these logics will be also investigated.

The first goal of this paper is to reply to a number of criticisms levied by Gunnar Breivik and Robert L. Simon against an account of sporting skills I published almost 20 years ago in which I distinguished between constitutive and restorative skills and examined their normative significance. To accomplish this goal, I first summarize my characterization and classification of skills and then detail the criticisms. After responding to the latter, and thus reconsidering and hopefully strengthening my account of skill (...) in sport, I turn my attention to Scott Kretchmar and Tim Elcombe’s inquiry into the skills involved in competitive sport. These authors claim that contesting skills demand the same respect usually accorded to testing skills. The second goal of this paper is then to explore Kretchmar and Elcombe’s inquiry under the light of my reconsidered analysis of skill. I specifically advocate a plausible relationship, both in terms of their distinctive character and relative import, between testing and contesting skills and constitutive and restorative skills. In doing so, I seek to present a more comprehensive account of skill in non-competitive and competitive sport. (shrink)

One important limitation of the current renditions of interpretivism is that its emphasis on the moral dimension of sport has overlooked the aesthetic dimension lying at the core of this account of sport. The interpretivist’s failure to acknowledge and consider the aesthetic implicitly distances this realm from the moral. Marcia Muelder Eaton calls this distancing the separatist mistake. This paper argues that interpretivism presupposes not only moral but also aesthetic principles and values. What it sets out to demonstrate is that (...) interpretivism is an integralist, or nonseparatist, account of sport, one in which ethical and aesthetic values are not exclusive. Making explicit and specifying interpretivism’s combined moral-aesthetic approach to sport not only helps to better distinguish the whole range of values that make up sport as well as their interconnection but also encourages sportspeople to pursue more coherent sport and, thus, more enriching lives.

Organized youth sport has become a prominent activity in Western societies, one around which myriad families structure their daily lives. Despite its popularity, or rather because of it, youth sport is besotted with complex problems. One distinctive set of problems pertains to children’s opportunities to benefit from engagement in sport. Such problems require a reflection on the conditions of justice. The goal of this paper is to explore ethical guidelines to make youth sport more just. The paper begins by characterizing (...) childhood, youth, and youth sport. Then, it articulates considerations of justice in youth sport. Together, these sections provide a basis to formulate the general features of a just youth sport. What emerges is a vision of youth sport that the adults involved in it should emphasize and implement if their young charges, and youth sport, are to flourish, as well as a novel approach to formulating and justifying normative criteria to make youth sport more just.

Trata-se de apresentar os caminhos de uma abordagem, cética em relação à política e seus mecanismos de sedução, bem como a sua imprevisibilidade.

Resumo: No presente ensaio, procuro estabelecer afinidade de leitura entre a tradição cética e a dialética, por intermédio do conceito de crítica.In this article I look to establish affinities between the skeptical tradition and the dialectic, by means of the concept of criticism.

Tanto desde el punto de vista teórico como desde una perspectiva práctica, el fenómeno de la "estetización" no parece ser portador de buenos augurios. En el ámbito teórico, la estetización ha sido vinculada con la crisis de los discursos orientados en términos de verdad, mientras que en el terreno práctico, ella ha sido asociada a ciertos procesos culturales que conducirían a la debacle de los principios normativos. Dejando de lado la problemática teórica, el presente trabajo se concentra en el debate (...) en torno al fenómeno práctico de la estetización de la política. En primer lugar, nos remontamos a la historia de la condena filosófica de la estetización de la esfera política para ocuparnos luego, en un segundo momento, de algunas posiciones esteticistas y antiesteticistas de finales del siglo XX. Posteriormente, procuramos avanzar en una redescripción de esta problemática que nos permita rescatar un sentido productivo de lo estético para el pensamiento político. Para esto último, nuestro trabajo se apoya en las reflexiones de la actual coeditora de la Neue Zeitschrift für Sozialforschung, Juliane Rebentisch. Tomando como parámetro algunos de los supuestos de sus investigaciones, aquí intentaremos demostrar hasta qué punto la estetización de la vida política puede contribuir al desarrollo de una concepción renovada de esta última. Both from a theoretical and from a practical perspective, the phenomenon of "aestheticization" does not seem to anticipate anything particularly good. On a theoretical level, it has been linked to the crisis of discourse-oriented in terms of truth, while in the practical, has been associated with certain cultural processes that lead to the the collapse of the normative principles. Leaving aside the theoretical issues, this paper focuses on the debate on the phenomenon of the aestheticization of the political culture. First, it goes back to the history of philosophical condemnation of the aestheticization of the political sphere. In a second time, he deals with some conceptions of the late twentieth century. Subsequently, the paper seeks to advance a redescription of this problem that allows rescue a productive sense of aesthetics for political thought. For the latter, our article is based on the reflections of Juliane Rebentisch and attempts to show how the aestheticization of political life can help to develop a new concept of the same. (shrink)

Addressing both collegiate and professional sports, the updated edition of Fair Play: The Ethics of Sport explores the ethical presuppositions of competitive athletics and their connection both to ethical theory and to concrete moral dilemmas that arise in actual athletic competition. This fourth edition has been updated with new examples, including a discussion of Spygate by the New England Patriots and recent discoveries on the use of performance enhancing drugs by top athletes. Two additional authors, Cesar R. Torres and Peter (...) F. Hager, bring to this edition a discussion of the moral issues involved in youth sports and the ethics of being a fan, as well as a fresh perspective on the theories of broad internalism and the quest for excellence. Furthermore, major criticisms of broad internalism by philosophers William J. Morgan and Scott Kretchmar add a new dimension to the discussion on the moral foundations of winning. (shrink)

Since 1993, when Hudelmaier developed an O(n log n)-space decision procedure for propositional Intuitionistic Logic, a lot of work has been done to improve the efficiency of the related proof-search algorithms. In this paper a tableau calculus using the signs T, F and Fc with a new set of rules to treat signed formulas of the kind T((A → B) → C) is provided. The main feature of the calculus is the reduction of both the non-determinism in proof-search and the (...) width of proofs with respect to Hudelmaier's one. These improvements have a significant influence on the performances of the implementation. (shrink)

The reflections around teacher training and the means by which it is treated in the educational contexts have major importance, due to the urgency of the topic as well as the multiplicity of ways to be dealt along with the teachers. From researches of images production, developed with children and teachers in the ambit of early childhood education, this text will reflect on the formative processes of teachers in the childhood education. In this context, there are a few relevant questions: (...) what can the image do in the formative processes? In which ways may the teacher training help us to think about the childhood and the educational practices with little children? By which means may the childhood help us to think the work of teacher training. In this way, using the produced images, this text aims to operate in the circulation movement of the thought itself, in which the thought can, in its exteriority, experiment with words, childhood, image and teacher training, enabling ruptures to think about the child, the educators, the school, the knowledge, the doing, the powers, the action protocols, what to do with the children and how to deal with them, composing possibilities that overflow what is determined and legalized. As theoretical basis, we take authors such as G. Agamben, G. Deleuze e Michel Foucault. (shrink)

El objetivo del siguiente artículo es observar los rendimientos de la hermenéutica filosófica para interpretar el problema de la confianza en nuestras relaciones sociales. En primer lugar, se identifican sus fundamentos para comprender a través de esta tradición filosófica su giro lingüístico e importancia para estudiar dicho concepto ; en segundo lugar, se analiza desde la idea del ‘lenguaje’ y del ‘diálogo’ el problema de la confianza en las relaciones contextuales. Por último, se reflexiona sobre cómo la racionalidad científica proyecta (...) confianza o desconfianza en un mundo en donde cada vez sus enunciados deben comprometerse con la vida humana. Este artículo es relevante pues busca revalorizar a la filosofía para el análisis de un concepto que ha sido estudiado principalmente desde las ciencias sociales. En este sentido nos apoyamos en la hermenéutica filosófica en pos de observar sus posibilidades para conceptualizar y analizar la confianza en la sociedad contemporánea. (shrink)

In this paper we propose a Kripke-style semantics for second order intuitionistic propositional logic and we provide a semantical proof of the disjunction and the explicit definability property. Moreover, we provide a tableau calculus which is sound and complete with respect to such a semantics.

This article aims to highlight the productivity of falsehood in the context of its asymmetrical position with truth. The core of the discussion can be summarized in the following statement: if only truths can be drawn from truths, it cannot be said that truth cannot be drawn from falsehood. The central thesis of the text is that the asymmetrical behavior of falsehood promotes the dissociation between the criterion (based on the conservation of truth) and the field of validity so that (...) the latter, broader than the former, incorporates the movement not only from truth to truth, but also from falsehood to falsehood and, above all, from falsehood to truth. The distinction between the symmetrical and asymmetrical fields allows understanding, for example, the emergence of certain logical fallacies, the separation between demonstration and deduction, the thesis of Popperian fallibilism, and the use of the hypothetical-deductive method. Truth does not have functions analogous to those of falsehood. (shrink)
