The autobiography of an influential medieval Catalan intellectual.

For this new anthology, Anthony Bonner has chosen central texts from his acclaimed two-volume compilation Selected Works of Ramon Llull. Available for the first time in an affordable format, these works serve as an introduction to the life and writings of the Catalan philosopher, mystic, and theologian who lived from 1232 to 1316. Founder of a school of Arabic and other languages, Llull was also a poet and novelist and one of the creators of literary Catalan. This volume contains (...) three prefaces on Llull's life, thought, and reputation. Of Llull's works, it offers Book of the Gentile and the Three Wise Men, his seminal Christian apology; the Ars brevis, a summary of his philosophical system; The Book of the Lover and the Beloved, a celebration of mystical love in the courtly tradition; and his wittily scathing Book of the Beasts.

Se trata de una antología que recoge los más importantes pasajes del pensamiento sobre los valores de Risieri Frondizi (1910-1983), uno de los más importantes axiólogos de América Latina. Además de la selección de fragmentos que integra la antología, José Ramón Fabelo Corzo escribe el Prólogo (que busca ubicar a Frondizi en el contexto histórico del pensamiento axiológico latinoamericano) y el Epílogo (en el que se realiza una valoración crítica de las propuestas de este destacado pensador argentino.

The field of neuroaesthetics attempts to identify the brain processes underlying aesthetic experience, including but not limited to beauty. Previous neuroaesthetic studies have focussed largely on paintings and music, while performing arts such as dance have been less studied. Nevertheless, increasing knowledge of the neural mechanisms that represent the bodies and actions of others, and which contribute to empathy, make a neuroaesthetics of dance timely. Here, we present the first neuroscientific study of aesthetic perception in the context of the performing (...) arts. We investigated brain areas whose activity during passive viewing of dance stimuli was related to later, independent aesthetic evaluation of the same stimuli. Brain activity of six naïve male subjects was measured using fMRI, while they watched 24 dance movements, and performed an irrelevant task. In a later session, participants rated each movement along a set of established aesthetic dimensions. The ratings were used to identify brain regions that were more active when viewing moves that received high average ratings than moves that received low average ratings. This contrast revealed bilateral activity in the occipital cortices and in right premotor cortex. Our results suggest a possible role of visual and sensorimotor brain areas in an automatic aesthetic response to dance. This sensorimotor response may explain why dance is widely appreciated in so many human cultures. (shrink)

Electrical brain activity modulation in terms of changes in its intensity and spatial distribution is a function of age and task demand. However, the dynamics of brain modulation is unknown when it depends on external factors such as training. The aim of this research is to verify the effect of deductive reasoning training on the modulation in the brain activity of healthy younger and older adults ( (mean age of 21 ± 3.39) and (mean age of 68.92 ± 5.72)). The (...) analysis reveals the benefits of training, showing that it lowers cerebral activation while increasing the number of correct responses in the trained reasoning task (). The brain source generators were identified by time-averaging low-resolution brain electromagnetic tomography (sLORETA) current density images. In both groups, a bilateral overactivation associated with the task and not with age was identified. However, while the profile of bilateral activation in younger adults was symmetrical in anterior areas, in the older ones, the profile was located asymmetrically in anterior and posterior areas. Consequently, bilaterality may be a marker of how the brain adapts to maintain cognitive function in demanding tasks in both age groups. However, the differential bilateral locations across age groups indicate that the tendency to brain modulation is determined by age. (shrink)

Cambios estructurales en el modelo económico apuntan a revalorizar el papel del trabajo en Cuba, indican expertos en mesa redonda convocada por BOHEMIA. Apremia descentralizar gestiones administrativas y que cada individuo sea responsable y participante, coinciden. Las motivaciones efectivas han de convertir al trabajo en primera necesidad y, junto a la educación de la familia, borrar la cultura del "rebusque". Formar en los valores del trabajo debe encontrar sustento en la realidad y sus ejemplos.

Se trata de una Mesa Redonda organizada por la revista Bohemia de Cuba sobre los jóvenes, la historia y la formación de valores. El texto es la transcripción del debate en el que participaron 7 especialistas de diferentes áreas.

El artículo aborda el desafío de una conceptualización de la realidad socio-histórica que rompa con la separación entre lo real como externalidad y el sujeto. Lo anterior pasa por redefinir la idea de objetividad. Se requiere encontrar un concepto de subjetividad constituyente que no sea operativo por reducciones al plano de las variables psicológicas, pero que tampoco se resuelva como simple expresión de procesos macrohistóricos. Desde un punto de vista metodológico, realza el contrapunto entre contenidos teóricos permanentes y la transitoriedad (...) de los sujetos. Se afirma que para poder armonizar desarrollo humano y desarrollo social, se requieren relaciones sociales que no impliquen dominación económica ni política. Llegado a esto, se pregunta: ¿Es que el capitalismo se esconde detrás de la democracia, por lo que ésta, en su propio nombre, se niega así misma? (shrink)

Desde su configuración como elemento estructurante del relato político moderno, la «sociedad civil» ha mantenido su vigor como institución conceptual, como muestra la continua ampliación de su significado. Sin embargo, precisamente por ello, el concepto revela una gran contaminación semántica, con usos poco homogéneos del mismo. Con vistas a clarificar todo esto, parece oportuno tratar de contextualizar esta noción así como valorar hasta qué punto sigue siendo pertinente como categoría analítica. Para ello, se ha optado por desgranar el ámbito material (...) de la sociedad civil desde las formas de agregación social más elementales hasta las más globales, las cuales reflejan la presencia de stakeholders privados con capacidad de orientar las políticas públicas que reclaman protagonismo desde la sociedad civil, pero también actores alternativos que reclaman una interpretación distinta de la «sociedad civil global».

Abstract:According to some authors, Latour's attention to politics during the last decades is the result of his proposing a different approach to politics that entails, with respect to his overall project, one of two situations. Either his epistemological proposal has suffered a "normative turn"—which necessarily breaks with the previous assumptions of Actor-Network Theory (ANT); or, if ANT's view on technosciences remains valid, his political proposal becomes not possible as a new normative approach. In this paper, I will focus on the (...) critique voiced by John Law, as well as Graham Harman. I will argue that this is a false dilemma because there has not been a change in Latour's conceptual basis, nor a lack of coherence within his thought that would undermine the democratic commitment of his Political Epistemology. I will justify this by exposing the fact that Latour's overall project, as part of Science Studies, has not lately followed a "political" but an "ontological" turn, which has been underling his works since the very beginning of ANT.

The presence and relevance of St. Cyprian and his writings in Thomas More's works has only been partially discussed in the available literature. In the present paper I intend to contextualize More's interest for St. Cyprian within the general appreciation that other humanists showed for the Fathers of the Church, and this African Bishop in particular. Thus a close review of More's references to St. Cyprian in his writings is here presented, organized in three blocks: the so-called “humanist letters,” his (...) controversial works—with the exception of The Confutation of Tyndale's Answer —and the Tower works. In the conclusion I will provide a tentative categorization of the uses More made of this Father of the Church. (shrink)

With a masterful sense of the place of rhetoric in both thought and practice and an ear attuned to the clarity, natural simplicity, and charm of Plato's Greek prose, James H. Nichols Jr., offers precise yet unusually readable translations of two great Platonic dialogues on rhetoric. The Gorgias presents an intransigent argument that justice is superior to injustice: To the extent that suffering an injustice is preferable to committing an unjust act. The dialogue contains some of Plato's most significant and (...) famous discussions of major political themes, and focuses dramatically and with unrivaled intensity on Socrates as a political thinker and actor. Featuring some of Plato's most soaringly lyrical passages, the Phaedrus investigates the soul's erotic longing and its relationship to the whole cosmos, as well as inquiring into the nature of rhetoric and the problem of writing. Nichols's attention to dramatic detail brings the dialogues to life. Plato's striking variety in conversational address is carefully reproduced, as is alteration in tone and implication even in the short responses. The translations render references to the gods accurately and non-monotheistically for the first time, and include a fascinating variety of oaths and invocations. A general introduction on rhetoric from the Greeks to the present shows the problematic relation of rhetoric to philosophy and politics, states the themes that unite the two dialogues, and outlines interpretive suggestions that are then developed more fully for each dialogue. The twin dialogues reveal both the private and the political rhetoric emphatic in Plato's philosophy, yet often ignored in commentaries on it. Nichols believes that Plato's thought on rhetoric has been largely misunderstood, and he uses his translations as an opportunity to reconstruct the classical position on right relations between thought and public activity.

The best known algebraizable logics with a conjunction and an implication have the property that the conjunction defines a meet semi-lattice in the algebras of their algebraic counterpart. This property makes it possible to associate with them a semi-lattice based deductive system as a companion. Moreover, the order of the semi-lattice is also definable using the implication. This makes that the connection between the properties of the logic and the properties of its semi-lattice based companion is strong. We introduce a (...) class of algebraizable deductive systems that includes those systems, and study some of their properties and of their semi-lattice based companions. We also study conditions which, when satisfied by a deductive system in the class, imply that it is strongly algebraizable. This brings some information on the open area of research of Abstract Algebraic Logic which consists in finding interesting characterizations of classes of algebraizable logics that are strongly algebraizable.

A logic in a finite language is said to be finitely presentable if it is axiomatized by finitely many finite rules. It is proved that binary non-indexed products of logics that are both finitely presentable and finitely equivalential are essentially finitely presentable. This result does not extend to binary non-indexed products of arbitrary finitely presentable logics, as shown by a counterexample. Finitely presentable logics are then exploited to introduce finitely presentable Leibniz classes, and to draw a parallel between the Leibniz (...) and the Maltsev hierarchies. (shrink)

Ramon Llull y el secreto de la vida descubre el enigmático mundo de este filósofo, místico y visionario (Mallorca, 1232-1316) que escribió unos 300 libros en catalán, latín y árabe recorriendo las principales capitales europeas, el Mediterráneo oriental y el norte de África con el claro propósito de comunicar y predicar un modelo místico de contemplación. El descubrimiento del «ars combinatoria», un nuevo lenguaje que tenía sus paralelismos en las técnicas de cabalistas y sufíes, encontraría numerosos admiradores en Europa, (...) desde los filósofos del Renacimiento ;que lo entendieron como un arte de la memoria; hasta los más recientes estudios, que lo ven como un precedente del lenguaje de la informática. Este libro quiere ofrecer una interpretación del pensamiento filosófico y religioso de Llull. La primera parte se vincula a la necesidad de comprensión de su propia experiencia extraordinaria. La segunda desarrolla la teoría de la contemplación mística.;En la tercera se estudian los diversos usos del lenguaje empleados por Llull. Y la cuarta incluye una selección de sus textos más representativos. (shrink)

This paper explores a notion of “the strong version” of a sentential logic S, initially defined in terms of the notion of a Leibniz filter, and shown to coincide with the logic determined by the matrices of S whose filter is the least S-filter in the algebra of the matrix. The paper makes a general study of this notion, which appears to unify under an abstract framework the relationships between many pairs of logics in the literature. The paradigmatic examples are (...) the local and the global consequences associated with a normal modal logic, and the logics preserving degrees of truth and preserving truth associated with certain substructural and many-valued logics. For protoalgebraic logics the results in the paper coincide with those obtained by two of the authors in 2001, so the main novelty of the approach is its suitability for all kinds of logics. The paper also studies three kinds of definability of the Leibniz filters, and their consequences for the determination of the strong version. In a second part of the paper several case studies are developed, comprising positive modal logic, Dunn–Belnap’s four-valued logic, the large family of substructural logics, and some relevance logics.

This study details the methodological process for creating a tool for the identification of COVID-19 potential contagion situations in sports and physical education before, during, and after practice and competition. It is a tool that implies an educational and methodological process with all the agents of the sports system. This tool identifies the large number of interactions occurring through sports action and everything that surrounds it in training, competition, and organization. The aim is to prepare contingency protocols based on an (...) exhaustive analysis, risk detection, and proposal of contingency measures trying to reduce the residual risk to a minimum. In the second part, the results of the implementation of this tool in the sports system of Galicia (Spain) are shown. The technicians have changed their perceptions about the coronavirus transmission in sports. They highlight the problem for returning to sports participation for athletes under 18 years in the pandemic context. (shrink)

En el pensamiento de H. Arendt, las lecturas sobre el totalitarismo de The Origins of Totalitarianism, pueden ser leídas en paralelo a sus lecturas sobre la sociedad de masas, de la labor y el consumo en The Human Condition. Nos interesa mostrar en este artículo que se trata de lecturas convergentes, que se encuentran ligadas en la evolución del pensamiento de la autora y conservan algunas notas temáticas comunes como la preocupación por: el aislamiento, la soledad, el desarraigo y el (...) proyecto de convertir a los seres humanos en seres superfluos.

A logic is selfextensional if its interderivability (or mutual consequence) relation is a congruence relation on the algebra of formulas. In the paper we characterize the selfextensional logics with a conjunction as the logics that can be defined using the semilattice order induced by the interpretation of the conjunction in the algebras of their algebraic counterpart. Using the charactrization we provide simpler proofs of several results on selfextensional logics with a conjunction obtained in [13] using Gentzen systems. We also obtain (...) some results on Fregean logics with conjunction. (shrink)

Luego de señalar algunos momentos específicos en la obra de Arendt, en los que la cuestión de la sentimentalidad aparece, sobre todo de manera crítica, nos centraremos en un aspecto específico de esta, de especial interés para nosotros: el lugar de la indignación a la hora de narrar, contar, construir la historia de una comunidad y a la hora de abrir e instaurar el espacio público, caracterizado por Arendt como el espacio de aparición más elemental, donde los otros aparecen ante (...) mí y yo aparezco ante los otros , haciendo surgir lo político. Esta perspectiva nos permitirá reconstruir la posible relación entre indignación y política, en el pensamiento de la autora alemana. Starting from highlighting some specific moments in Arendt’s works critically dealing with sentimentality matters, we will focus on a specific aspect: the place of indignation when narrating, telling, and constructing the history of a community and, at the same time, opening a public space. This is characterized by Arendt as an elementary space, where others appear to me and I appear before them. , originating the political aspect. This view allows us to rebuild the possible relationship between indignation and politics in this German author’s views. (shrink)
