El presente trabajo tiene como objetivo realizar un análisis contextual de la direccionalidad del marxismo latinoamericano desde la muerte de José Carlos Mariátegui hasta nuestros días. Inevitablemente, este empeño tropieza con las diversas formas en que se ha manifestado el pensamiento de izquierda, con sus disímiles proyecciones, y, sobre todo, con la forma en que ha enfrentado los distintos acontecimientos históricos en el continente. En este sentido, el trabajo parte de la forma auténtica de marxismo, cuya expresión más genuina fue (...) el pensamiento de Mariàtegui,asì como los alejamientos posteriores respecto al marxismo clásico, vislumbrados preferentemente en los posicionamientos teóricos de algunas figuras en la etapa controversial del “empobrecimiento” del marxismo en América Latina(1941-1958).Se reflexiona en torno al mantenimiento de esta tradición crítica del marxismo latinoamericano y la forma que entroniza con otras tendencias de pensamiento denominadas que se ubican dentro de la perspectiva del “pensamiento crítico”.

The Clock es una videoinstalación en la que el ritmo ficticio del celuloide se humaniza a través de un relato que opera desde la anacronía del apropiacionismo de imágenes de archivo. Marclay utiliza en su montaje diferentes mecanismos de dislocación narrativos, sonoros y visuales que, unidos al uso anacrónico de la imagen fílmica, generan una experiencia heterocrónica en el espectador. El resultado es la generación de una alternativa al concepto de espacio-tiempo normalizado que es resignificado como un concepto multirrítmico y (...) heterogéneo, ofreciendo la posibilidad de pensar otra realidad que nos devuelve la autonomía y el control de su experimentación.

In this work we present the complex relationship between sound and color in musical creation throughout history that continues to be fruitful in current musical composition. Synesthesia in music establishes a correspondence between sound and color and has been a constant debate since the 17th century. The complex nature of sound appears from ancient Greece in the school of Pythagoras in which the number becomes the configurator of harmony. Since then, different aesthetic attempts have arisen to relate color and sound (...) that reach today's electronic procedures in contemporary music. (shrink)

Resumen: En este trabajo se presenta un abordaje explicativo del enfoque epistemológico -tal como es definido por J. Padrón- propio de la corriente de pensamiento convencionalmente denominada teoría crítica. En la primera parte abordamos su dimensión ontológica a través de la categoría de totalidad, tal como T. Adorno y M. Horkheimer la desarrollan a lo largo de sus trabajos, en oposición al empirismo popperiano. En la sección siguiente damos cuenta de la dimensión gnoseológica de la teoría crítica, desarrollando las reflexiones (...) y discusiones en torno a lo político en la producción científica y empleando como eje conductor el debate entre K. Popper y T. Adorno, con especial énfasis en el vínculo entre ciencia y praxis, entre producción de conocimiento científico e intencionalidad crítica y transformadora del mundo social, lo cual constituye un fundamento parcialmente meta-teórico clave para este enfoque. Finalmente, en las conclusiones, explicitamos algunas implicancias de lo trabajado para la investigación social actual: la centralidad de oponer a la creciente fragmentación e hiperespecialización del campo científico la noción ontológica de totalidad y la necesidad de acompañar la construcción crítica del conocimiento con una adecuada metacrítica de la posición teórica y práctica del investigador.: In this paper, we discuss the epistemological approach -as defined by J. Padrón- called critical theory. In the first part, we explain its ontological dimension through the category of totality, as T. Adorno and M. Horkheimer develop it throughout their works, in opposition to Popperian empiricism. In the following section, we analyse the gnoseological dimension of critical theory around the political in scientific production, using as a driving axis the debate between K. Popper and T. Adorno with special emphasis on the link between science and praxis, the production of scientific knowledge and a critical and transformational intentionality of the social world, which constitutes a partially meta-theoretical basis for this approach. Finally, in the conclusions, we explain some central implications for the current social research: the increasing fragmentation and hyper specialization of the scientific field against the ontological notion of totality, and the need to follow the critical construction of knowledge with an adequate meta-critical theoretical and practical position of the researcher.

In this article we present the profound relationship between the ideas of the Ancient Greek tradition and the aesthetics that underlies the composition at hand, Chant de Linos, a 1944 work for flute and piano by André Jolivet. Jolivet configures his language in this work from the ideas about the music that he receives from the Greek tradition and from the mythical history of Lino. We will illuminate the context and production of Jolivet at this creative stage.

La noción de Ley –del mismo modo que las nociones de Estado o de Nación– no es sino una entelequia que enmascara tras de sí una ausencia sustancial. Su existencia no posee otro objetivo que el de brindar un sostén simbólico capaz de velar ese vacío originario, haciendo de nuestro mundo un lugar menos acosado por la incertidumbre. De acuerdo con esto, el objetivo del presente trabajo es el de internarnos en una búsqueda que pueda conducirnos nuevamente hacia ese suelo (...) originario, hacia ese momento cero de la institución. El ensayista Michel de Montaigne oficiará de guía en esa búsqueda. Él nos conducirá hacia el terreno en el cual la solidez de los fundamentos parece desvanecerse, o, más bien, hacia el momento simbólico en el cual una mera decisión humana, tan arbitraria como contingente, da origen a aquellas normas que poco a poco, gracias a esa maestra violenta y traidora que es la costumbre, habrán de ser veneradas en su aparente intemporalidad. The notion of law –as the notions of state or nation– is nothing but an entelechy that masks behind it a substantial absence. Its existence has no other purpose than to provide us with a symbolic support able to veil that originating void, making our world a place less hurried by uncertainty. In accordance with this, the aim of the present paper is to begin a search that may lead us back to the original soil, to the time zero of institution. The essayist Michel de Montaigne will be our guide. He will lead us to the land on which the strength of the foundation seems to vanish, or, rather, to the symbolic moment in which a mere humane, arbitrary and contingent decision gives rise to those standards who gradually, thanks to the violent and treacherous teacher who is custom, start to be worshiped in his apparent timelessness.

The aim of this article is to examine Kierkegaard’s criticism of Metaphysics. Therefore, firstly I will analyze Kierkegaard’s concept of being as interesse (interest), which allows Kerkegaard’s criticism, not just because Metaphysics implies ideality and abstraction, but also because it hides the ethical. That is why I will finally argue the ethical background of the existential thought and its opposition to any tentative of thinking the ethical as a First Philosophy.

We investigate the problem of “wave packet reduction” in quantum mechanics by solving the Schrödinger equation for a system composed of a model measuring apparatusM interacting with a microscopic objects. The “instrument” is intended to be somewhat more realistic than others previously proposed, but at the same time still simple enough to lead to an explicit solution for the time-dependent density matrix. It turns out that,practically, everything happens as if the wave packet reduction had occurred. This is a consequence of (...) the fact that the apparatus is made up of a very large number of microsystems interacting withs. More precisely, our model shows that the “macroscopic size” of a measuring apparatus can lead by itself to a density matrix for the systemM + s which is physically equivalent to the density matrix of a statistical mixture corresponding to the reduced wave packet.

Education is a fundamental pillar in human development, and its evolution throughout history has been influenced by a variety of factors, including imaginative culture and human nature. In this study, we explore how educational methods have evolved in response to the interaction between these two aspects. We look at how human creativity, imagination, and adaptation have influenced the way we teach and learn, from early forms of knowledge transmission to more contemporary approaches focused on active student engagement and the development (...) of practical skills. Our research is based on a comprehensive review of the academic literature in the fields of education, evolutionary psychology, cultural anthropology, and imagination studies. We explore how societies have used imagination as a tool to transmit knowledge and values, as well as to foster creativity and individual expression. We also examine how adaptive aspects of human nature, such as the ability to learn collaboratively and adapt to changing environments, have influenced the way educational methods are designed. Our results show a clear evolution in educational methods over time, from approaches focused on the one-way transmission of knowledge to more interactive and participatory models that encourage exploration and discovery. We identify common patterns in the way societies have used imagination and adaptation to promote learning and socialization and discuss the implications of these findings for contemporary education. In conclusion, this study highlights the importance of understanding the relationship between imaginative culture, human nature, and education. It provides a solid foundation for the design of educational methods that harness the innate creativity and adaptability of human beings and offers guidance for educators and policymakers on how to promote meaningful and lasting learning in today's world.

Abstract1 June 2018 marked a historic moment in Spanish politics, when the Spanish Socialist Workers’ Party (Partido Socialista Obrero Español, PSOE) announced a cabinet with the largest proportion of female ministers in the world. This announcement received extensive coverage in the traditional media. The objective of this research was to measure whether the news had an equivalent impact on Twitter users. To this end, we analyzed the reaction to the appointments based on the popularity of the hashtags #GobiernoSanchez (“Sanchez Government”), (...) #GobiernoFeminista (“Feminist Government”) and #ConsejoMinistras (“Council of Female Ministers”). The most significant findings are that women had even less visibility than they were given in traditional media because of what is not retweeted does not exist, and that the extreme polarization of political life and the media in the public sphere appears to extend to the digital environment of Twitter.

RESUMENEn este ensayo intento pagar una deuda pendiente que todos tenemos con Aron Gurwitsch y recuperar, para nuestra memoria, su importante contribución a la fenomenología durante los años que él estuvo exiliado en Francia (1933-1940). Fue él quien introdujo el pensamiento de Kurt Goldstein en Francia y fue él el primero en comprender (en los años veinte) que estaba naciendo un nuevo enfoque en las ciencias humanas y sociales y que hay una coincidencia entre ellas y la nueva filosofía fenomenológica (...) de Husserl: una tendencia a ir a las cosas tal como son vividas y manejadas por los sujetos. Este espíritu de confluencia entre la fenomenología y las otras ciencias es lo que le transmitió a Maurice Merleau-Ponty, su alumno y contertulio, pero sin que él reconociera nunca en sus escritos a Gurwitsch como una gran «fuente de inspiración» para su pensamiento. En este ensayo se presentan evidencias sobre la deuda impagada de Merleau-Ponty con respecto a Aron Gurwitsch.PALABRAS CLAVEGurwitsch – Merleau-Ponty – Goldstein – Fenomenología – Psicología de la GestaltABSTRACTIt is our aim in this essay to pay off a debt we owe to Aron Gurwitsch and to retrieve for our memory his important contribution to phenomenology during his years of exile in France (1933-1940). While there, he introduced the thought of Kurt Goldstein´s thought and was the first to understand that a new approach in the human and social sciences was emerging and converging with Husserl’s new phenomenological philosophy: a tendency towards things such as they are lived and handled by subjects. This spirit of confluence between phenomenology and the sciences is something he passed on to his younger colleague, Merleau-Ponty, who did not acknowledge Gurwitsch as a major «source of inspiration» for his thought. Some evidence of Merleau Ponty´s unpaid debt to Aron Gurwitsch is presented in this essay.KEY WORDSGurwitsch – Merleau-Ponty – Goldstein –Phenomenology – Gestalt´s Psychology. (shrink)

A network of dates, persons, activities and publications relating to the beginning of phenomenology in France is listed below, thus enabling to substantiate the direct objective of this essay: estimate how much Aron Gurwitsch contributed to the reception of phenomenology in France during the 1930s, to what extent he contributed, how and when. The indirect objective is to establish the legacy of Gurwitsch in France after he was exiled to the United States. Another objective is related tacitly with this: to (...) show that in his Parisian stage Gurwitsch was not merely in a kind of transit, unimportant, “between” the life of the novice researcher in Germany and life of the relevant phenomenolgist in the US. He played an important role in France. This to the point that without Gurwitsch, probably French phenomenology would not have followed the path it followed in the years after his departure. Yet, paradoxically, this crucial role was exercised implicitly and has had to be explicated. (shrink)

Insight into Lester Embree’s C.V. Recovery and recognition of his inner purpose with regard to his critical detachment from a particular orientation of phenomenology. Phenomenological theory only makes sense as prepa-ration for real practice. When did the view that we, the “soi disant” phenomenologists, are far from the genuine practice of phenomenology arise in Embree? And, who inspired him, apart from Husserl himself? These are key questions to understand unity and inner coherence in Embre’s C.V., and they meet two aims. (...) The first one is to find the link between his initial entry in phenomenology and his critical stance, particularly evident in the last two decades of his life. The second one is to identify who could have been his guide and model‒apart from Husserl‒from the beginning of his life as phenomenologist until his last two decades, when he wrote his comments on pseudophenomenology. In any case, Embree has been a critical voice who compels us to think about the orientation we are giving to the phenomenology inherited from Husserl. He is therefore a brave and honest philosopher, full of great humanity. In addititon to these qualities, it is worth noting both his creative intelligence and foresight to see‒earlier than others‒the evolution followed by phenomenology until now and his valuable multidisciplinary contribution. Praise to Lester Embree.Mirada hacia el interior del C.V. de Lester Embree. Recuperación y reconocimiento de su propósito interno con respecto a su distanciamiento crítico hacia cierta orientación de la fenomenología. La teoría fenomenológica únicamente tiene sentido como preparación para una real práctica. ¿Cuándo emerge en Embree su consideración de que los “soi disant” fenomenólogos estamos alejados del verdadero ejercicio de la fenomenología? Y, ¿en quién se inspira él además de en Husserl? Estas preguntas son importantes para entender la unidad y coherencia internas en el C.V. de Embree y sirven para satisfacer dos objetivos. El primero es hallar un vínculo entre su entrada inicial en la fenomenología y su posicionamiento crítico manifiesto especialmente en las últimas dos décadas de su vida. El segundo objetivo es determinar quién pudo actuar para él —además de Husserl— como guía y modelo desde el comienzo de su vida de fenomenólogo hasta esas dos últimas de su vida en las que escribe sus comentarios sobre la pseudofenomenología. En todo caso, Embree es una voz crítica que nos fuerza a pensar acerca de la trayectoria que nosotros estamos dando a la fenomenología heredada de Husserl. Él es, así, un filósofo valiente y honesto y de una gran humanidad. Se unen a estas cualidades su gran inteligencia creativa y su sorprendente perspicacia para ver —antes que otros— la evolución que ha seguido la fenomenología hasta hoy y la valiosa contribución multidisciplinar actual. Alabanza a Lester Embree. (shrink)

The goal of synthetic biology is to create artificial organisms. To achieve this it is essential to understand what life is. Metabolism-replacement systems, or (M, R)-systems, constitute a theory of life developed by Robert Rosen, characterized in the statement that organisms are closed to efficient causation, which means that they must themselves produce all the catalysts they need. This theory overlaps in part with other current theories, including autopoiesis, the chemoton, and autocatalytic sets, all of them invoking some idea of (...) closure. A simple model of an (M, R)-system has been implemented in the computer, and behaves in ways that may shed light on the requirements for a prebiotic self-organizing system. In addition to a trivial steady state in which nothing happens, it can establish a non-trivial steady state in which all intermediates have finite concentrations, with their rates of degradation balanced by their rates of synthesis. The system can be regenerated from the set of food components plus a single intermediate, and maintain itself in that state indefinitely, despite continuous degradation. At the very low compartment volumes that may have existed in prebiotic conditions, for example in cavities in minerals, or in micelles formed by simple amphiphiles, statistical fluctuations in the numbers of molecules need to be taken into account. With the stochastic approach there is no non-trivial steady state in strict mathematical terms, because the system will always collapse to the trivial state after sufficient time. However, the average time before collapse is so long for volumes greater than $10^{-19}\;{\textsc{l}}$ (much smaller than the volume of the order of $10^{-15}\;{\textsc{l}}$ for a typical bacterial cell) that for practical purposes the self-maintaining state of non-null concentrations becomes significant, recalling the situation of bistability that is observed in deterministic analysis. In turn, there exists a minimum size below which the self-organizing system cannot maintain itself on chemically relevant time scales. The value of the critical volume depends on the particular concentrations and rate constants assumed, but the principle could apply generally. (shrink)
