It was shown in the early seventies that, in Local Quantum Theory (that is the most general formulation of Quantum Field Theory, if we leave out only the unknown scenario of Quantum Gravity) the notion of Statistics can be grounded solely on the local observable quantities (without assuming neither the commutation relations nor even the existence of unobservable charged field operators); one finds that only the well known (para)statistics of Bose/Fermi type are allowed by the key principle of local commutativity (...) of observables. In this frame it was possible to formulate and prove the Spin and Statistics Theorem purely on the basis of First Principles.In a subsequent stage it has been possible to prove the existence of a unique, canonical algebra of local field operators obeying ordinary Bose/Fermi commutation relations at spacelike separations.In this general guise the Spin–Statistics Theorem applies to Theories (on the four dimensional Minkowski space) where only massive particles with finite mass degeneracy can occur. Here we describe the underlying simple basic ideas, and briefly mention the subsequent generalisations; eventually we comment on the possible validity of the Spin–Statistics Theorem in presence of massless particles, or of violations of locality as expected in Quantum Gravity.

The paper reconstructs Beauvoir's interpretation of the Marxist and the Freudian contributions to our understanding of the feminine condition. A number of epistemological assumptions derived from Sartre's philosophy are pointed out. Beauvoir's reading of Marx, Engels, and Freud is discussed claiming that her reading is biased by humanistic and historicist assumptions.

O desafio da epistemologia é compreender o que é o conhecimento científico e como o cientista chega a ele, do mesmo modo tudo que orbita este caráter, o que inclui a senciência, logo a relação epistemólogo e sua condição de ‘estar-no-mundo’ que podem ser suspensos, refletido e analisado. A senciência é capacidade dos seres humanos e alguns organismos mais simples de perceber e sentir as emoções, sentimentos e afetações positivas e negativas de forma consciente e impostar-se sobre os excedentes esta (...) relação. O epistemólogo é um filósofo e um pesquisador acadêmico especialista em fazer reflexões, críticas, reduções e reavaliações das identidades estabelecida nas bases do fazer científico. Neste sentido, qual é o lugar da senciência na epistemologia quanto à percepção do pesquisador epistemólogo? O objetivo visualizar o papel da senciência na epistemologia. A justificativa versa em compreender a senciência na vida mental dos cientistas na construção do conhecimento científico, pois mesmo nas mentes lúcidas, há zonas obscuras. Adotou-se o método fenomenológico, é essencialmente de inclinação qualitativa e descritiva, logo trata das discrições de fenômenos da consciência, da experiência e vivências, ações e comportamentos. O lugar da senciência na epistemologia versa no descontentamento da percepção pueril/realista e professoral/cientista do pesquisador epistemólogo, uma vez que a senciência se figura para além da consciência de autoconsciência.

Recent popularity of the relationship of 'ethics' and 'economics' is at once revealing and misleading. It marks the withering away of a dogmatic confidence in a self-regulating and water-proof economic 'sphere'. It is also a muddled way of treating a number of interrelated but different issues: the interrelations between moralities (as historically given institutions) and markets (as partially self-regulating socially institutionalized mechanisms), the relationship between ethics and economic theory, and finally issues of distributive justice.

In this article we scrutinize what can be called an "experimentalist dogma" presupposed in Pablo Melogno's analysis of empirical incommensurability in the chemical revolution. According to Melogno, the fact that experimental methods were preserved throughout the chemical revolution was an indication that there were no relevant perceptual differences between Joseph Priestley and Antoine Lavoisier. In order to refine Melogno's general analysis, we will present a taxonomy of varieties of empirical incommensurability and discuss their relationships. To exemplify this categorization, and to (...) show its metatheoretical adequacy, we will apply it to the neuronist revolution, that is, to the process of discovery of the neuron in the late 19th and early 20th centuries within neuroanatomy, taking as our main case study the controversy between Camillo Golgi and Santiago Ramón y Cajal. From the analysis of the controversies regarding dendritic spines and stellate cells of the cerebellum, in particular, we question the experimentalist dogma, highlighting how, in these controversies, the conservation of experimental practices does not guarantee the similarity of perceptual contents. Moreover, we will argue that, all other experimental conditions being equal, differences in experiential content between Golgi and Cajal are best explained by differences in their commitments to incompatible conceptual schemes.

O texto visa contribuir, por um lado, à investigação acerca dos processos psicológicos, aos níveis subjetivo, lógico e intersubjetivo, inerentes a uma postura filosofante, remetendo a considerações metodológicas com relação ao ensino de Filosofia. Por outro, visa questionar a relação entre o filosofar e a História da Filosofia, visando à conexão entre o diálogo filosófico e o diálogo com a História da Filosofia.

Recently, Piccinini and Craver have stated three theses concerning the relations between functional analysis and mechanistic explanation in cognitive sciences: No Distinctness: functional analysis and mechanistic explanation are explanations of the same kind; Integration: functional analysis is a kind of mechanistic explanation; and Subordination: functional analyses are unsatisfactory sketches of mechanisms. In this paper, I argue, first, that functional analysis and mechanistic explanations are sub-kinds of explanation by scientific (idealized) models. From that point of view, we must take into account (...) the tradeoff between the representational/explanatory goals of generality and precision that govern the practice of model-building. In some modeling scenarios, it is rational to maximize explanatory generality at the expense of mechanistic precision. This tradeoff allows me to put forward a problem for the mechanist position. If mechanistic modeling endorses generality as a valuable goal, then Subordination should be rejected. If mechanists reject generality as a goal, then Integration is false. I suggest that mechanists should accept that functional analysis can offer acceptable explanations of cognitive phenomena. (shrink)

El debate académico sobre el significado político de los derechos humanos ha puesto el acento en su dimensión negativa o privada, olvidando la dimensión positiva o pública que despliegan en el proceso de integración de una sociedad política determinada, como la democrática. El artículo rescata la dimensión política de los derechos humanos como un elemento constitutivo clave de la sociedad democrática. La hipótesis de que parte es que los derechos humanos otorgan carta de naturalidad a una lucha real a favor (...) de la libertad política y contra la opresión que encuentra su materialización histórica en la sociedad democrática y su negación en la sociedad totalitaria. Para desarrollar el argumento, recurre a la teoría de Claude Lefort, quien asocia el discurso de los derechos humanos con una concepción general de la sociedad que se realiza históricamente en la sociedad democrática.

En este trabajo busco aproximarme a una historia in-finita de la naturaleza en el pensamiento-en-imagen de Paul Klee a partir de una interpretación de los parágrafos 76 y 77 de la Crítica de la facultad de Juzgar de Kant. Para su lectura, propongo considerar como contrapunto uno de los principios del entendimiento puro que Kant considera en la Crítica de la razón pura, este es: el principio de las anticipaciones de la percepción. A saber, el principio que explica la condición (...) de toda sensación. Para preguntar por una historia in-finita de la naturaleza es fundamental atender a la diferencia implicada en la relación entre naturaleza y arte que advierte Klee. Dicha diferencia conlleva considerar el origen de esta historia como fractura por la atención puesta hacia lo que la diferencia, lo cual exige pensar en lo que denomino un cambiode percepción.

Qual o sentido da vida? Por que aqui estamos? Será destino? Será escolha? Neste livro, Mario Sergio Cortella e Leandro Karnal, dois dos maiores pensadores contemporâneos no Brasil, se encontram para refletir sobre essas questões que há séculos fascinam e intrigam a humanidade. A ciência, a filosofia, a religião e a arte têm oferecido algumas possibilidades de resposta que os autores discutem aqui. Afinal, pode ser aterrador imaginar que não há um destino, algo que explique a nossa existência. Por (...) outro lado, a ausência de sentido nos deixa livres para ser e viver conforme desejarmos - embora isso implique também responsabilidade. Mas somos mesmo livres? Seja escolha ou destino, seja a vida um drama que vamos tecendo ou uma tragédia anunciada, fato é que estamos sempre a procurar algum propósito que torne a existência mais significativa. Mas o que explica que algumas pessoas tenham mais sucesso do que outras no que fazem? Seria dom, vocação ou resultado de um esforço? Como os autores apontam, talvez a vida seja menos inspiração e mais transpiração. (shrink)

This chapter provides a brief overview of the history of behavioral neurology, dividing it roughly into six eras. In the ancient and classical eras, emphasis is placed on two transitions: firstly, from descriptions of head trauma and attempted neurosurgical treatments to the exploratory dissections during the Hellenistic period and the replacement of cardiocentrism; and secondly, to the more systematic investigations of Galenus and the rise of pneumatic ventricular theory. In the medieval through post-Renaissance eras, the scholastic consolidation of knowledge and (...) the role of compendia are emphasized, along with the use of new methods from within a mechanistic framework. With the discovery of electrical conductance and the rise of experimentalism, we frame the modern era as period of intense debate over localization, decomposition, and other mechanistic principles, and marked by rapid discovery about the brain. The chapter ends with a discussion of the contemporary era, focusing on the establishment of behavioral neurology research on aphasia, apraxia, and neuropsychiatric conditions. (shrink)

This paper focuses on order-preserving logics defined from varieties of distributive lattices with negation, and in particular on the problem of whether these can be axiomatized by means Hilbert-style calculi that are finite. On the negative side, we provide a syntactic condition on the equational presentation of a variety that entails failure of finite axiomatizability for the corresponding logic. An application of this result is that the logic of all distributive lattices with negation is not finitely axiomatizable; we likewise establish (...) that the order-preserving logic of the variety of all Ockham algebras is also not finitely axiomatizable. On the positive side, we show that an arbitrary subvariety of semi-De Morgan algebras is axiomatized by a finite number of equations if and only if the corresponding order-preserving logic is axiomatized by a finite Hilbert-style calculus. This equivalence also holds for every subvariety of a Berman variety of Ockham algebras. We obtain, as a corollary, a new proof that the implication-free fragment of intuitionistic logic is finitely axiomatizable, as well as a new corresponding Hilbert-style calculus. Our proofs are constructive in that they allow us to effectively convert an equational presentation of a variety of algebras into a Hilbert-style calculus for the corresponding order-preserving logic, and vice versa. We also consider the assertional logics associated to the above-mentioned varieties, showing in particular that the assertional logics of finitely axiomatizable subvarieties of semi-De Morgan algebras are finitely axiomatizable as well.

El artículo tiene por objeto analizar la construcción del conocimiento mapuche según el discurso de kimches. Sostenemos que en la educación familiar existe un proceso de construcción de conocimientos propios como un sistema de saberes y contenidos educativos para la formación de personas. La metodología empleada es la investigación educativa. Los resultados parciales muestran una descripción acerca de la lógica de los conocimientos educativos propios, para contextualizar la enseñanza y el aprendizaje de las ciencias en el medio escolar, desde la (...) educación intercultural en contexto mapuche. The aim of this article is to analyze the construction of Mapuche knowledge based on the kimches speech. We argue that within family education, there exists a process of constructing their own knowledge, as a system of knowledge and educational contents for forming individuals. The research methodology applied corresponds to education research. Preliminary results describe the logic of individual educational knowledge from intercultural education in the Mapuche context, so as to contextualize the teaching and learning of Science in schools.

En el presente ensayo se expone y discute la idea de que el lenguaje, más allá de ser un medio de comunicación, se manifiesta como poesía; esto en el sentido de que es en el lenguaje, donde diariamente se configura el mundo con sentido humano. Poesía del lenguaje aparece como una expresión que busca dar cuenta de la energía creadora del lenguaje a la hora de instituir la realidad en la dimensión lingüística de esta. La discusión toma la forma de (...) comentarios a y diálogo con tesis de pensadores como Heidegger, Saussure, Benjamin, Maturana, y de poetas como Novalis, Neruda, Huidobro, con el propósito de elucidar la dimensión poética del lenguaje y sus efectos prácticos y morales en la vida social.

En su ensayo Para una crítica de la violencia, Walter Benjamin reivindica el fenómeno social de la huelga general revolucionaria teorizada por Georges Sorel en su obra Reflexiones sobre la violencia, como una figura ejemplar de lo que sería un “medio puro de la política”, al margen de cualquier forma legitimada de poder. En este marco, pocos comentadores contemporáneos advierten una discordancia conceptual entre ambos filósofos: para Sorel, la huelga revolucionaria es un mito social, mientras que el mito, categoría esencialmente (...) negativa en Benjamin, describe la violencia que aprisiona la vida y que se traduce en una forma de poder político superior. En este artículo quisiéramos demostrar esta discordancia conceptual para examinar en seguida cómo ha sido comentada por otros pensadores contemporáneos. La filosofía de la historia, la posibilidad de una acción política ética y la temporalidad mesiánica aparecen en el horizonte teórico que emparenta a estos filósofos y por el cual podría descifrarse su impasse conceptual. Esto se confirma si se despliega la idea de un “medio puro de la política”, pista que Benjamin ofrece sin profundizar y sobre la cual reenvía al pensamiento de un filósofo poco explorado, Erich Unger. En la última parte de este artículo desarrollaremos las claves dadas por Unger, que entran justamente en sintonía con la mención de la huelga general como medio puro de la política. In his Critique of violence, Walter Benjamin claimed that the social phenomenon of the revolutionary general strike was an example of what would be a “pure political mean”. In this context, not many contemporary commentators note an important conceptual incoherence between those two philosophers: for Sorel the revolutionary general strike is a social myth, while in Benjamin the category of myth, essentially negative, describes the violence that imprisons life and crystallizes it in a higher form of political power. In this article, we demonstrate this conceptual discrepancy in order to examine the way it has been approached by other philosophers. The philosophy of history, the possibility of an ethical political action, and messianic temporality, all appear on the theoretical horizon linking these philosophers, and through these ideas a conceptual impasse can be decoded. Moreover, this horizon can be confirmed if we follow the idea of a “pure political means” that Benjamin proposes and which moves forward to the thought of an unexplored philosopher mentioned by him: Erich Unger. In the last part of this article we will develop the keys given by Unger, which fall right in line with the notion of the general strike as a pure political mean. (shrink)

Este artículo analiza los aspectos metodológicos principales del proyecto heideggeriano de una ontología fundamental. Heidegger considera que no hay un punto de partida privilegiado, porque todos estamos hermenéuticamente situados. Por ello propone que la investigación filosófica comience justo donde ya nos encontramos. Esto significa que debemos apropiarnos de nuestra situación hermenéutica. La explicación de esta idea mostrará la clave metodológica de la ontología heideggeriana: la indicación formal. Ella habilita un acceso al fenómeno sin abandonar el marco de la facticidad.

La pandemia del SARS-CoV-2 ha creado un desafío sin precedentes para la educación. En 2020, como resultado de las medidas para reducir la propagación del SARS-CoV-2, muchas instituciones educativas pasaron del aprendizaje presencial al aprendizaje remoto. Sin embargo, este modelo educativo puede generar estrés y ansiedad adicionales a la ansiedad provocada por la pandemia. Los objetivos del presente estudio fueron: 1) comparar las perspectivas de estudiantes y docentes sobre el número de horas dedicadas a las clases, y 2) determinar las (...) principales dificultades que enfrentan docentes y estudiantes, respectivamente, al pasar al sistema de educación en línea. Para realizar esta investigación se realizó una encuesta online en países de habla hispana, utilizando una muestra de 1.048 participantes anónimos. A través de los datos recopilados. Se analizaron el uso de plataformas, los tipos de equipos, los niveles de angustia y las posibles razones de esta angustia. Esta pandemia es una de las amenazas de salud pública más importantes de la historia reciente y ha afectado nuestras vidas de manera significativa, siendo una de las más importantes la futura adaptación de escuelas, estudiantes y docentes a una nueva forma de aprender.

These two volumes consist of a critical edition and English translation of the two earliest known Armenian sets of scholia on the Heavenly Hierarchy of Dionysius the Areopagite. Composed in the monastic schools of Erznka in the late thirteenth century, these scholia provide significant insight into how the Heavenly Hierarchy in particular, and Armenian translations of Greek texts in general, were understood by Armenian scholars in the Middle Ages. This editio princeps of the scholia represents a rare critical edition of (...) a native Armenian composition from the medieval period. In addition to the text and translation, these volumes include a textual commentary as well as a critical collation and English translation of a number of scholia from the Armenian version of the Greek scholia on the Heavenly Hierarchy.

A pesar de la relevancia que ganó el pensamiento de Jean-François Lyotard con la publicación de La Condition postmoderne (1979), solo un pequeño número de publicaciones académicas han abordado sus primeras propuestas en el campo de la estética. Este artículo pretende contribuir a la tarea de enmendar semejante error. Para ello se propone una aproximación general y sistemática a sus primeros usos del concepto de figura, comenzando por sus precedentes e influencias y concluyendo con la afirmación de que la estética (...) de Lyotard no expone una mera filosofía de las artes o una filosofía de la percepción, sino una auténtica ontología. Para facilitar la comprensión de esta cuestión, se abordarán algunos de sus conceptos más complejos, como el de figura-matriz, y se harán pequeñas aproximaciones a la producción de artistas como Joan Fontcuberta y Peter Tscherkassky, cuya obra explicita el tema central de este artículo: la poética, la política y la ontología de la figura.
