En este artículo discutiré algunos problemas lógicos de la omnipotencia que van más allá de las clásicas paradojas ligadas a esta noción. Presentaré una versión refinada de la paradoja de Fitch sobre la omnipotencia que tiene en cuenta la distinción entre acciones básicas y derivadas, así como la distinción entre la capacidad de hacer algo y la mera posibilidad metafísica de hacerlo. También explico cómo esta paradoja puede reformularse para obtener una versión afín a la paradoja del mentiroso que afecta (...) a la consistencia de ciertas nociones de omnipotencia. Por último, evalúo algunas posibles respuestas disponibles para el teísta y un intento de usar la paradoja de Fitch como argumento a favor de la existencia de Dios. (shrink)

Who or what is the historical subject? – Andersian outlooks between psychopolitics and datism In this paper I will question the equivalence between mankind and historical subjectivity. Following the philosopher Günther Anders’ thoughts about industrial revolutions and technological development, I will outline the changes technology is forcing over mankind, to the point of a potential change of roles. The digital turn shows how this is still an ongoing process, as I will highlight referring to the works by the philosopher Byung-Chul (...) Han and the historian Y. N. Harari. The internet, as well as algorithms and Big Data, marks a trend showing the synthetic being becoming more relevant than the biological one. (shrink)

There is now compelling evidence that motor imagery (MI) promotes motor learning. While MI has been shown to influence the early stages of the learning process, recent data revealed that sleep also contributes to the consolidation of the memory trace. How such “online” and “offline” processes take place and how they interact to impact the neural underpinnings of movements has received little attention. The aim of the present review is twofold: i) providing an overview of recent applied and fundamental studies (...) investigating the effects of MI practice on motor learning, and ii) detangling applied and fundamental findings in support of a sleep contribution to motor consolidation after MI practice. We conclude with an integrative approach of online and offline learning resulting from intense MI practice in healthy participants, and underline research avenues in the motor learning/clinical domains.

Contemporary art, which explodes from the borders and identifiable genres, the dance requires to be discussed in a perspective that exceeds the narrow of the sector. It is a microcosm of the world, a privileged space for observing the displacements and tensions of the contemporary world whose stake is a new posture that redesigns the body map in the society of capital and in the era of relations mediated by the mechanisms of the network. The result is a unique field (...) of analysis to explore with the work of Michele Di Stefano, one of the most interesting figures in the advanced front of contemporary choreography. Space, time and aesthetic categories mark this path of reflection. (shrink)

La pensée du corps. Un parcours esthétique chez le dernier Merleau-PontyLe but de cette contribution est de chercher à reconstruire un parcours théorique, entre plusieurs autres possibles, en mesure de montrer comment l’art, en particulier la peinture, incarne chez le dernier Merleau-Ponty la possibilité d’un autre type de pensée. Il s’agit de la tentative de suivre une idée qui semble faire son chemin au sein de la réflexion que l’auteur consacre à la Nature et puis à l’Etre brut et sauvage, (...) ou bien aussi dans celle d’une pensée enracinée dans la corporéité, qui devient une chose qui pense et qui fait penser. Une hypothèse de sens qui ouvre à une investigation de la chair humaine, et qui aboutit au résultat visible de cette pensée qui est corps et qui trouve dans la vision de l’art moderne ses signes les plus paradigmatiques.Il s’agit d’un itinéraire exégétique qui propose, en substance, un double plan: d’une part, une lecture de l’essence du corps, dans la facticité primordiale de la Nature, dans lequel se loge une sorte d’ontologie de la cavité et, de l’autre, le résultat philosophique possible d’une corporéité qui pense et qui, à travers l’art de la peinture, fait voir une pensée non plus fondée sur la représentation, en dernière instance, une pensée post-métaphysique. Et cela n’est pas sans conséquences pour le rapport de l’homme avec le monde et avec la philosophie.The Thought of Body. An Aesthetic Path in the Final Merleau-PontyThe purpose of this contribution is to try to reconstruct a theoretical path, between several other possibilities, capable of showing how art, in particular painting, incarnates in the final Merleau-Ponty the possibility of another type of thinking. What is at issue is an attempt to follow an idea which seems to make its way within the reflection that Merleau-Ponty dedicates first to Nature, and then to brute and wild Being, or as well in that of a thought rooted in corporeity, which becomes a thing which thinks and which requires thinking. We are following a hypothesis concerning the sense which opens to an investigation of human flesh, and which leads to the visible result of this thought which is body and which finds its most paradigmatic signs in the vision of modern art.What is at issue is an exegetical itinerary which proposes, in substance, a double plan: on the one hand, a reading of the essence of body, in the primordial facticity of Nature, in which a sort of ontology on the cavity lodges itself and, on the other hand, the possible philosophical result of a corporeity which thinks and which, through the art of painting, makes see a thought no longer founded on representation, and is, at the end of the day, a post-metaphysical thought. And that is not without consequences for the relation of the human with the world and with philosophy. (shrink)

Motor Imagery reproduces cognitive operations associated with the actual motor preparation and execution. Postural recordings during MI reflect somatic motor commands targeting peripheral effectors involved in balance control. However, how these relate to the actual motor expertise and may vary along with the MI modality remains debated. In the present experiment, two groups of expert and non-expert gymnasts underwent stabilometric assessments while performing physically and mentally a balance skill. We implemented psychometric measures of MI ability, while stabilometric variables were calculated (...) from the center of pressure oscillations. Psychometric evaluations revealed greater MI ability in experts, specifically for the visual modality. Experts exhibited reduced surface COP oscillations in the antero-posterior axis compared to non-experts during the balance skill. Experts further exhibited reduced length of COP displacement in the antero-posterior axis and as a function of the displacement area during visual and kinesthetic MI compared to the control condition. Predictive relationships were found between the stabilometric correlates of visual MI and physical practice of the balance skill, as well as between the stabilometric correlates of kinesthetic MI and the training experience in experts. Present results provide original stabilometric insights into the relationships between MI and expertise level. While data support the incomplete inhibition of postural commands during MI, whether postural responses during MI of various modalities mirror the level of motor expertise remains unclear. (shrink)

This study aimed to investigate the student-athletes' capability to face the academic, sport, and social challenges during the coronavirus disease 2019 (COVID-19) lockdown and to disclose novel aspects of dual careers. A 32-item online survey encompassing demographic characteristics, sport and university engagement, support and dual-career benefits, physical activity, sitting time, and the time deemed necessary to recover the previous level of performance was developed. Four hundred sixty-seven student-athletes (males: 57%, females: 43%) from 11 countries, competing in 49 different sports (individual: (...) 63.4%, team: 36.6%) at regional (17.5%), national (43.3%), and international (39.2%) levels, and enrolled at high school (21.9%) and university (78.1%) levels completed the survey. During the lockdown, the respondents decreased the time dedicated to sport and academics, although they maintained an active lifestyle. Student-athletes from countries under severe contagion were more likely to train at home, dedicate to academics, and receive support from the coach but less likely receive support from their teachers. With respect to their team sport counterparts, athletes competing in individual sports trained more and were more likely to receive support from their coaches. International athletes showed the highest training time and support from their coaches and as student-athletes. High school students received more support from their coaches and teachers, whereas university students were more likely considering dual careers useful to cope with the COVID-19 pandemic. This study substantiates the relevant role of competitive sports participation in the maintenance of active lifestyles, with student-athletes considering home training and e-learning valuable resources during the lockdown. Furthermore, their sport and academic commitments helped student-athletes cope with the emergency of the COVID-19 pandemic. (shrink)

ABSTRACTWe introduce the variety of Many-Valued-Weak rigs. We provide an axiomatisation and establish, in this context, basic properties about ideals, homomorphisms, quotients and radicals. This new class contains the class of product MV-algebras presented by Di Nola and Dvurečenskij in 2001 and by Montagna in 2005. The main result is the compactness of the prime spectrum of this new class, endowed with the co-Zariski topology as defined by Dubuc and Poveda in 2010.

Este artículo examina la concepción racionalde Hare sobre los juicios morales.Para ello, critica tajantemente la concepcióne mo t i v i s t a de l o s Po s i t i v i s t a s l ó g i c o s yde St e ve ns on. Tambi é n, s e di s t anc i a de lintuicionismo moral concebido por Moore ensus Principia Ethica de 1903. Para desarrollarel racionalismo moral parte del principio (...) queel lenguaje moral hace parte del lenguaje engeneral, del cual no puede ser desligado puescuando hacemos razonamientos morales estosse encuentran sometidos por las diferentesreglas de la lógica clásica. Por ello, Hare aplicala lógica clásica a su teoría de los imperativosy considera la ética como el estudio lógico dellenguaje moral.También se muestran las semej anzas y lasdiferencias entre la concepción de Austin y deHare, destacando la evolución del pensamientode este último filósofo. Cuando Hare escribiósu obra El Lenguaje de la Moral no estabai nf l uenci ado por l a t r i cot omí a de Aust i nsobre Los actos de habla como: Locucionarios,ilocucionarios y perlocucionarios. Influenciaq u e s e o b s e r v a e n e s c r i t o s p o s t e r i o r e s .Mi e nt r a s Ha r e ubi c a l os j ui c i os mor a l e sen l o l ocuci onari o, Austi n l os ubi ca en l oilocucionario; controversia que nos conducea r e f l e xi ona r s obr e l a i mpor t a nc i a de l apragmática en los juicios morales y a la vezsobre su racionalidad.I n t hi s pa pe r , I e xa mi ne Ha r e ’ s r a t i ona lconception on moral judgements. For this, hecriticizes sharply the emotivist conception ofLogical Positivists and of Stevenson. He alsoaparts himself from Moore’s moral intuitionism,as expounded in Principia Ethica. To developmoral rationalism, Hare starts from the principlethat moral language is apart of the generallanguage, from which it cannot be separatedsince when we do moral reasonings these areruled by the different rules of classical logic.For this reason, Hare applies classical logic tohis theory of imperatives and considers ethicsas the logical study of moral language.I also show the similarities and differencesbetween Austi n’ s and Hare’ s concepti ons,emphasizing the evolution of the thought of thelater. When Hare wrote The language of morals,he was not under the influence of Austin’stricotomic view of speech acts: locutionary,illocutionary and perlocutionary, influence thatwe can see in later works. While Hare locatesmoral judgments in the locutionary, Austin doesit in the illocutionary. This controversy leadsus to think on the importance of pragmatics inmoral judgements as well as on its rationality. (shrink)

El libro de Alex Ibarra, Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, plantea la discusión sobre las líneas filosóficas, demostrando la existencia de cierta tradición analítica en Chile. A partir de allí, reflexionamos en torno a los procesos de constitución del campo de la filosofía en Chile como una historia atravesada por la necesidad de préstamos y cruces que impiden una delimitación clara de sus límites, lo que tornaría necesaria la atención a ciertas (...) políticas de la lectura que el libro soslaya. La productividad de la filosofía producida en Chile surgiría gracias -y no pese- a su inscripción en sus tiempos y espacios, a partir de recepciones cuya ausencia de retraso no impide el gesto de cierto re-trazo de lo leído. Alex Ibarra's exposition in his book Filosofía chilena. La tradición analítica en el periodo de la institucionalización de la filosofía, places the discussion on the philosophical traditions, showing the existence of a certain kind of analytical tradition in Chile. From there, we expose the processes of constitution of the field in Chile as a history crossed by the need of importations and intersections that contest the clear delimitation of its boundaries, what makes necessary the attention of the politics of readings that the book avoid. The productivity of the philosophic production in Chile, arises thanks to -but not in spite of- its inscription in its age/times and spaces, coming from its receptions and its differences. (shrink)

The present contribution comments Prof. Ciancio´s conception on the relationship between freedom and being, understood as the ontologically originary relation, and tries out an interpretation of some of its main thesis, taking also into account the methodical aspects. Finally, suggest a possible convergency way with phenomenological approaches, which chose the methodological priority of a way leading to the principles, ratherof a way departing from them.

It seems natural to think of an unwilling addict as having a pattern of preferences that she does not endorse—preferences that, in some sense, she does not ‘identify’ with. Following Frankfurt (1971), Jeffrey (1974) proposed a way of modeling those features of an agent’s preferences by appealing to preferences among preferences.Th„e addict’s preferences are preferences she does not prefer to have. I argue that this modeling suggestion will not do, for it follows from plausible assumptions that a minimally rational agent (...) must prefer those first-order preferences she actually has. I close by considering two different but related ways to think about the initial phenomenon. (shrink)

In this introduction the coordinators of the First Congress of Postcolonial Studies (Buenos Aires, 5th, 6th, 7th December 2012) review some of the main questions and guidelines which characterized the workshops. Starting from a heated debate on the categories and the epistemological proposals developed by postcolonial studies and decolonial feminism, the Congress accepted the challenge of producing a South/South dialogue through the consolidation of a space of interdisciplinary discussion in the different theorical fields inquiring post-colonial experience.

Se busca rastrear la imagen que Platón tiene de Heráclito y articularla con la estructura argumentativa del Cratilo, para comprender las necesidades textuales a las que responde la doctrina del flujo perpetuo, es decir, la discusión sobre la corrección (ὀρθότης) del nombre. Gracias a la inclusión del testimonio heraclíteo, resulta posible rastrear la presunta consolidación de la tesis sobre los nombres primarios y los secundarios como el eje de la separación entre dos planos de realidad (uno estable y uno móvil) (...) y de la teoría de las Ideas -es decir, como la base de la epistemología platónica presente en los diálogos de madurez-. The article seeks to trace the image Plato has of Heraclitus and connect it with the argumentative structure of the Cratylus in order to understand the textual needs that give rise to the doctrine of perpetual flux, that is, the discussion regarding the correctness (ὀρθότης) of names. The inclusion of Heraclitus's testimony makes it possible to trace the alleged consolidation of the thesis regarding primary and secondary names as the axis of separation between two levels of reality (one stable, the other, changing) and the theory of Ideas -that is, as the basis of Plato's epistemology as set forth in the late dialogues-.

En este trabajo argumento que sólo mediante un enfoque y un tratamiento wittgensteinianos se pueden disolver las pseudo-dificultades filosóficas concernientes a los colores. Sostengo que, aunque los hechos que de los que se ocupa la ciencia son fundamentales para que pueda gestarse el lenguaje de los colores, lo que la ciencia tiene que decir es enteramente irrelevante para inquietudes concernientes al significado, utilidad, enseñanza y aprendizaje, etc., del lenguaje de los colores. Asumiendo una perspectiva wittgensteiniana, se puede hacer ver que (...) los problemas filosóficos concernientes a los colores son efectivamente artificiales, porque plantean interrogantes en los que los nombres de los colores no son usados. Lo que nos debe interesar es describir su aplicación, explicar para qué nos sirve el lenguaje de colores, qué utilidad de hecho presta dicho juego de lenguaje. Doy por sentado que las palabras para colores no se usan solas sino en oraciones, en conexión con verbos de percepción y recojo dos contrastes de verbos como ‘ver’. Por una parte, ‘ver’ apunta tanto a propiedades objetivas de las cosas como a experiencias visuales de los hablantes. Por otra parte, los verbos psicológicos como ‘ver’ están marcados por una asimetría fundamental entre la primera y la tercera personas. Ambas distinciones tienen consecuencias para el lenguaje de los colores, porque éste sirve para lidiar con el mundo a través de nuestras vivencias. Éstas, sin embargo, son relevantes en la medida en que quedaron lingüistizados, esto es, cuando los hablantes ya se volvieron usuarios de la terminología de los colores, es decir, ya adscriben y reconocen correctamente las propiedades cromáticas de los objetos. ¿Para qué nos sirve entonces el lenguaje de los colores? En primera persona indico que tengo ciertas vivencias que son gracias al lenguaje comprensibles para otros y le doy garantías a mi interlocutor de que puedo lidiar con objetos ; en tercera persona me permiten describir la conducta exitosa de alguien en procesos de reconocimiento y manipulación de objetos. La presuposición fundamental del enfoque wittgensteiniano es la existencia de una comunidad lingüística. Comprendemos entonces que los nombres para colores, como cualesquiera otras palabras, se aprenden a través de un proceso de enseñanza ostensiva, ensayo y error, interacción permanente entre hablantes y aprendiz, premios y castigos, etc. Aplico también la idea de que, contrariamente a como proceden los filósofos, las palabras para colores no se usan solas, sino en oraciones y en conexión con actividades, esto es, con formas de vida. Los conceptos de juegos de lenguaje y formas de vida son pues los instrumentos que se requieren para superar los enredos filosóficos en torno al color. (shrink)
