Standpoint logic is a recently proposed formalism in the context of knowledge integration, which advocates a multi-perspective approach permitting reasoning with a selection of diverse and possibly conflicting standpoints rather than forcing their unification. In this paper, we introduce nested sequent calculi for propositional standpoint logics---proof systems that manipulate trees whose nodes are multisets of formulae---and show how to automate standpoint reasoning by means of non-deterministic proof-search algorithms. To obtain worst-case complexity-optimal proof-search, we introduce a novel technique in the context (...) of nested sequents, referred to as "coloring," which consists of taking a formula as input, guessing a certain coloring of its subformulae, and then running proof-search in a nested sequent calculus on the colored input. Our technique lets us decide the validity of standpoint formulae in CoNP since proof-search only produces a partial proof relative to each permitted coloring of the input. We show how all partial proofs can be fused together to construct a complete proof when the input is valid, and how certain partial proofs can be transformed into a counter-model when the input is invalid. These "certificates" (i.e. proofs and counter-models) serve as explanations of the (in)validity of the input. (shrink)

Considering Rosmini’s political works in comparison with his metaphysical and anthropological essays, and starting from Rosmini's project of a code of law that, in the author’s opinion, can guarantee fundamental human rights, this article discusses the concept of justice between citizens and outsiders. Its first part is an analysis of Rosmini’s juridical fundaments, which takes into account also some objections historically moved against it. Its second part examines some specific cases of conflicts between outsiders and the members of civil society, (...) as considered by the Roveretan philosopher. (shrink)

I defend the hypothesis that the semantic paradoxes, the paradoxes about collections, and the sorites paradoxes, are all paradoxes of reference fixing: they show that certain conventionally adopted and otherwise functional reference-fixing principles cannot provide consistent assignments of reference to certain relevant expressions in paradoxical cases. I note that the hypothesis has interesting implications concerning the idea of a unified account of the semantic, collection and sorites paradoxes, as well as about the explanation of their “recalcitrance”. I also note that (...) it does not necessarily imply that one should not expect the sometimes hoped for “unique” solution to a paradox of these kinds. (shrink)

“Hay momentos en la vida en los que la cuestión de saber si se puede pensar distinto de como se piensa o percibir distinto de como se ve es indispensable para seguir contemplando o reflexionando” (Foucault, 2003, p. 8). Esta declaración foucaultiana es la que impulsa la voluntad genealógica que presenta este ensayo, así como su pretensión proyectiva para pensar hoy la educación. El momento filosófico crítico consiste en volver sobre las prácticas que día a día llevamos a cabo y (...) configuran nuestras vidas y nuestras instituciones. Este es necesario para realimentar y reorientar la savia de las instituciones, y especialmente la savia de nuestras instituciones académicas, suelo en el cual se teje la sustancia ética que posteriormente dará lugar a la articulación social. Si se aplica el elemento crítico que la actividad filosófica supone a la experiencia de la educación, entendiendo por ella la correlación dentro de una cultura entre campos de saber, tipos de normatividad y formas de subjetividad, podemos preguntarnos: qué es la educación y qué función desempeña hoy con respecto al ejercicio mismo del pensamiento en un contexto atravesado por las nuevas tecnologías y la IA.

La sociedad del siglo XXI ha sufrido una mutación histórica en lo que respecta a los métodos de producción y los impactos derivados de la generación de información. Este período se caracteriza por su inmersión en el entorno digital, donde los individuos, como ciudadanos, se encuentran bajo la manipulación, por un lado, de sus datos mediante técnicas de vigilancia y, por otros, expuestos a cámaras de resonancia mediática. Este panorama plantea desafíos significativos en cuanto a la manera en que interactúan (...) con la información y cómo esta afecta sus vidas. La relación entre los medios de comunicación y los acontecimientos, además, se encuentra atravesada por el concepto de interpretación, donde la capacidad de comprender y la habilidad para reconstruir narrativas son elementos que determinan la comprensión y el sentido de lo que ocurre en nuestro mundo.

Explorar la posibilidad de una nueva micropolítica crítica del signo a partir de Foucault, inspirada en la genealogía nietzscheana, y examinar las políticas y estrategias de alfabetización mediática e informacional necesarias para desarrollar competencias digitales en la transformación del ecosistema mediático es una tarea fundamental del quehacer filosófico actual. La pregunta por la posibilidad de la verdad retorna en un contexto en el que el pluralismo semiótico y la conducción mediática son dos elementos que rigen y ordenan la sociedad actual, (...) sociedad que se caracteriza por la abundancia de información y la omnipresencia de los medios de comunicación como tecnologías de poder. Desgranar su significado y vínculo nos conduce directamente al estudio del poder y el signo en relación con los efectos de la verdad de la posverdad. En este marco conceptual, la obra de Foucault proporciona herramientas teóricas valiosas para afrontar esta problemática. (shrink)

Quien enseña sin emancipar no solo embrutece, predicaba Joseph Jacotot, sino que también adoctrina. Pasado un siglo y medio desde entonces, el filósofo y esteta francés emérito de la Universidad de París VIII y European Graduate School Jacques Rancière, en un ejercicio característico de la filosofía de la educación, publica en 1987 El maestro ignorante a partir de la experiencia de Jacotot. A lo largo de su vida y producción literaria, Rancière reflexiona concienzudamente sobre la naturaleza del proceso de enseñanza (...) y aprendizaje humano y se pregunta: ¿es posible enseñar? ¿qué decide el alumnado en su proceso de aprendizaje? ¿Cuáles son los límites de la palabra transmitida en el aprendizaje? ¿Es la determinación del saber un ejercicio del poder? ¿Son todos los seres humanos capaces de comprender lo que otros hacen y saben? ¿Qué relación hay entre el poder del maestro y el poder de la palabra?

Quadruple Helix Collaborations (QHCs) is a cooperation model in which industry, government, academia, and the public interact to innovate. This paper analyses the impact of a training intervention to provide specific knowledge, skills, and attitudes to deal with barriers commonly found in the progress of QHCs. We designed, implemented, and evaluated three training programs in Austrian, Colombian, Danish, and Spanish institutions. We analysed trainees’ (n = 66) and trainers’ (n = 9) perceptions to identify the competencies acquired with the intervention (...) and the approach’s limitations. We used online questionnaires (35 trainees; 9 trainers), semi-structured interviews (10 trainees), and a focus group (6 trainers). Trainees answered positively regarding their self-perception about the impact of the course and highlighted the acquisition of inspiration for their practice (score 4.1 out of 5.0) and knowledge (3.7). In contrast, they perceived that a deeper interaction with other participants (2.7) was challenging. After the courses, 74% of respondents indicated that they know more about how QHCs work in practice, and 86% about collaboration or engagement methods. Moreover, participants plan to be more sensitive towards setting common goals (71%) and power imbalances (63%). Trainers’ perceptions align with those expressed by participants, except that they considered that the interaction amongst participants during the course was higher. Qualitative analysis of interviews with participants and the focus group with trainers provides more detail about the strengths and weaknesses of the intervention. Our study shows that the collaborative design and implementation of training impact the participant’s learning competencies, with potential implications in their medium- to long-term practice.

Drawing on many areas of expertise, from paleontology to psychology, Tomasello offers a plausible, evolutionary story abouthow our ancestors are likely to have developed cooperative behaviors and collaborative lifeways in order to survive and thrive.He also claims that this narrative explains why they would have begun to think in characteristically cooperative and moral ways,developing a “we is greater than me” [we>me] psychological orientation. Do the arguments offered support this extra claim? Thisarticle suggests that they do not. It seeks to alleviate (...) this shortcoming by drawing upon some conceptual resources offered bySartre’s Theory of Practical Ensembles. The centerpiece of the article consists of a detailed analysis of Sartre’s account of the genesisof the “group-in-fusion,” seeking to show that the genesis of a we-way of thinking in a group made up of many requires themediation of what Sartre calls a “third party” (le tiers). After closely examining Sartre’s treatment of the “third party” in theapocalyptic genesis of the “group-in-fusion,” I evaluate the success of this notion in resolving those questions that Tomasello’saccount raises while, at the same time, addressing the ontological question concerning the nature of the individual-grouprelation, in a way that suggests new and significant alternatives to standard dilemmas in contemporary social philosophy.

Traditionally, the “Imagery Debate” has opposed two main camps: depictivism and descriptivism. This debate has essentially focused on the nature of the internal representations thought to be involved in imagery, without addressing at all the question of action. More recently, a third, “embodied” view is moving the debate into a new phase. The embodied approach focuses on the interdependence of perception, cognition and action, and in its more radical line this approach promotes the idea that perception is not a process (...) involving internal world-models. The anti-representationalist version of the embodied paradigm covers, among others that we shall not discuss here, two quite different positions, namely the enactive approach and sensorimotor theory. Up to now these two anti-representationalist accounts have generally been confounded. In this paper we will argue that despite some important commonalities, enactive and sensorimotor accounts come with distinctive theoretical traits with regard to their approach to imagery. These become manifest when critically examining the role they assign to sensorimotor engagements with the world. We shall argue that enactive and sensorimotor approaches are different in their understanding of the role of embodied action, and these different notions of embodiment lead to different explanatory accounts of perception and imagery. We propose that, due to existing ambiguities in enactivism, the sensorimotor theory is a better framework for a skill-based approach to imagery. (shrink)

Modern humans are probably a product of social and anatomical preadaptations on the part of our Miocene australopithecine ancestors combined with the increasingly high amplitude, high frequency climate variation of the Pleistocene. The genus Homo first appeared in the early Pleistocene as ice age climates began to grip the earth. We hypothesize that this co-occurrence is causal. The human ability to adapt by cultural means is, in theory, an adaptation to highly variable environments because cultural evolution can better track rapidly (...) changing environments than can genes. High resolution ice and sediment cores published in the early 1990s showed the last ice age was characterized by high amplitude millennial and submillenial scale variation, exactly the sort of variation mathematical models suggest should favor a costly capacity for culture. More recent cores suggest that over the last several 100 thousand year glacial cycles the amount of millennial scale variation has increased rather dramatically in parallel with increases in hominin brain size and sophistication of the artifacts they made.

What do we owe each other when we act together? According to normativists about collective action, necessarily something and potentially quite a bit. They contend that collective action inherently involves a special normative status amongst participants, which may, for example, involve mutual obligations to receive the concurrence of the others before leaving. We build on recent empirical work whose results lend plausibility to a normativist account by further investigating the specific package of mutual obligations associated with collective action according to (...) our everyday understanding. However, our results cast doubt on a proposed obligation to seek the permission of co-actors before exiting a collective action, and suggest instead that this obligation is a function of explicit promising. We then discuss how our results pave the path for a new normativism, a theory that neither under- nor overshoots the target given by our common conception of the interpersonal obligations present in collective action.*.

Open peer commentary on the article “Constructivist Model Building: Empirical Examples From Mathematics Education” by Catherine Ulrich, Erik S. Tillema, Amy J. Hackenberg & Anderson Norton. Upshot: I argue that radical constructivism poses a series of deep methodological constraints on educational research.

As one tries to grasp love and its images within José Leonilson's production, a multiplicity of aspects and meanings are seen that also relate to Louise Bourgeois's oeuvre in regard to the interest in human relations.

Many arguments have been made against gene editing. This paper addresses the commonly invoked argument that gene editing violates human dignity and is ultimately a subversion of human nature. There are several drawbacks to this argument. Above all, the concept of what human dignity means is unclear. It is not possible to condemn a practice that violates human dignity if we do not know exactly what is being violated. The argument’s entire reasoning is thus undermined. Analyses of the arguments involved (...) in this discussion have often led to the conclusion that gene editing contravenes the principle of genetic identity (genetic immutability) thereby subverting a requisite of human dignity and ultimately threatening human nature. This paper refutes these arguments and shows that any opposition to gene editing cannot rely on the human dignity argument. (shrink)

The ontological turn (OT) is a loose cluster of theoretical approaches within cultural anthropology that advocates a synthetic, overarching way forward for ethnographically oriented cultural anthropology. We argue that in order to contribute substantively to ethnobiology the OT needs to distance itself from a long-standing tradition of thinking within ethnography that assumes some kind of fundamental divide between the natural and the social sciences. This distancing seems especially unlikely in light of the meta-anthropological nature of the OT as primarily a (...) perspective on ethnographic methodology. Instead, we advocate for naturalistic theoretical alternatives for thinking about human sociality, where philosophical innovation develops in concert with ongoing empirical work across the biological, cognitive, and social sciences. We illustrate this perspective by drawing on two naturalistic accounts likely to prove more fruitful for ethnobiological practice, namely, trans-genera models of sociality and progenerative views of kinship.

Through the reconstruction of Leibniz's theory of the degrees of knowledge, this e-book investigates and explores the intrinsic relationship of imagination with space and time. The inquiry into this relationship defines the logic of imagination that characterizes both human and non-human animals, albeit differently, making them two different species of imaginative animals. -/- Lucia Oliveri explains how the emergence of language in human animals goes hand in hand with the emergence of thought and a different form of rationality constituted by (...) logical inferences based on identity and contradiction, principles that are out of reach of the imagination. The e-book concludes that the presence of innate principles in human animals transforms the way in which they sense-perceive the world, thereby constantly increasing the distinction between human and non-human animals. -/- Keywords: human and non-human animals, Leibniz and Locke on ideas, Leibniz on bodies, Leibniz on conceivability, Leibniz on degrees of knowledge, Leibniz on degrees of perception, Leibniz on innate ideas, Leibniz on modality, Leibniz on similarity and congruence, Leibniz on space and time, Leibniz’s philosophy of language, theory of types.

En este ensayo el autor supera la contradicción teórica existente entre la Relatividad General que define el campo gravitacional como un aspecto geométrico del espaciotiempo, bien como potencial o curvatura, y la Gravedad Cuántica que lo define como una fuerza de interacción fundamental, con el cambio de la concepción del espaciotiempo de propiedad geométrica estructural del campo gravitacional, a la concepción del espaciotiempo propiedad geométrica estructural de la materia en movimiento. El espaciotiempo no es continente de la materia (Substancialismo) sino (...) que por el contrario está contenido en la materia en cuanto constituye la estructura geométrica que le da su forma y permite sus cambios, a la cual como espacio le confiere su capacidad de contener y como tiempo su capacidad de devenir. Tampoco, el espaciotiempo es la categoría de las relaciones geométricas de los cuerpos materiales y sus eventos (Relacionismo), puesto que, no es una propiedad relacional de la materia sino la propiedad estructural espacio-temporal geométrica de la materia, a la cual la dota con sus capacidades de auto contenerse y transformarse. La teoría del autor sobre el espaciotiempo es la de la materia intrínsecamente dinámica, dotada estructuralmente de las cuatro dimensiones de espaciotiempo, autocontenida espacialmente y auto deviniendo temporalmente, puesto, que la materia en su capacidad de contener dinámicamente ésta ensimisma contenida y transformándose. La partícula-onda, de la materia y del campo, no existe en el espaciotiempo, sino que éste es la propiedad geométrica intrínseca estructural de la partícula-onda, por lo tanto, adherida a su propia naturaleza interna, como su propiedad geométrica dimensional intrínseca, que con fuerza de ley se manifiesta en sus mediciones cuantitativas, bien cuando es tomada la partícula-onda en sí o en relación con otras. Así, sólo son posibles las teorías sobre la gravedad provenientes de la Gravedad Cuántica, aunque, deben reformularse renunciando a integrarlas con la visión geométrica derivada de las ecuaciones de la llamada “General Relatividad”.

Gravity is the foundation of the current physical paradigm. Due to that gravity is strongly linked to the curvature of space-time, we research that it lacks of a valid physical concept of space-time, nevertheless that from the science philosophy, via substantivalism, it has tried respond. We found that is due to that the gnoseological process applied from the general relativity, necessarily us leads to metaphysic because ontologically space-time is a metaphysical entity. Thus, we arrive to the super substantivalism that from (...) metaphysics gives an answer on space-time rigorously exact with the vision of Einstein on physics. The result is that matter is nothing since all is space-time, i.e. geometry, therefore is a imperative of the physical science break the current paradigm. (shrink)

Presentamos lo básico de la teoría relativista de la gravitación, con la inclusión de textos originales, de varios papeles, publicados entre 1987 y 2009, por sus autores: S. S Gershtein, A. A Logunov, Yu. M Loskutov y M. A Mestvirishvili junto con las introducciones, resúmenes y conclusiones elaborados por el autor de este papel.

No obstante, integrada a la teoría Entwurf de Grossmann-Einstein, en su desarrollo ulterior, por parte de estos autores, por lo tanto, preserva las leyes de conservación de la energía-impulso y del impulso angular conjuntamente del campo gravitacional y los demás campos materiales existentes en la naturaleza, en el espaciotiempo efectivo de Riemann, mediante su identidad con el espaciotiempo pseudo Euclídeo de Minkowski.

Two strong contenders for scalar implicature (SI) computation are the pragmatic and the grammatical theories. While the former sustains that context plays a major role, the latter suggests context is required but is lexically and monotonically constrained (Chierchia 2012). In particular, this paper discusses a processing account for SIs that is dependent on the satisfaction of the Strawsonian presupposition of existence, necessary for the realization of the asymmetric entailment pattern among relevant alternatives. This observation complies with the principles of the (...) grammatical view, for it predicts SIs in the presence of contextually empty domains, unlike the pragmatic account whose necessary access to contextual information will cause propositions with empty domains to always return a truth value false, hence blocking any inference. I present online experimental evidence of an acceptability judgment task and recorded response times of both existential and universal sentences containing entities of three kinds: existent (type-a), non-existent but conceivable (type-b), and non-existent and inconceivable (type-c). The data of 25 Colombian Spanish speaking participants were collected using PsychoPy, powered by Pavlovia. The results suggest SIs are computed in types a and b but relatively unsuccessful in type-c. I conclude that the relevant entailment pattern for implicature computation is the Strawson-entailment relation which, combined with the grammatical account, correctly predicts SIs with non-existent but conceivable entities but avoids inference with inconceivable terms.

Based on the various documents, 1989-2002, through the original texts, in addition to the author's contributions, this paper presents the refutation of the mathematicians and physicists A. Logunov and M. Mestvirishvil of A. Einstein's "general relativity", from the relativistic theory of gravitation of these authors, who applying the fundamental principle of the science of physics of the conservation of the energy-momentum and using absolute differential calculus they rigorously perform their mathematical tests. It is conclusively shown that, from the Einstein-Grossman-Hilbert equations, (...) gravity is absurdly a metric field devoid of physical reality unlike all other fields in nature that are material fields, interrupting the chain of transformations between the different existing fields. Also, in Einstein's theory the proved "inertial mass" equal to gravitational mass has no physical meaning. Therefore, "general relativity" does not obey the correspondence principle with Newton's gravity. (shrink)

In this essay the author overcomes the theoretical contradiction between General Relativity that defines the gravitational field as a geometric aspect of spacetime, either as potential or curvature, and Quantum Gravity that defines it as a fundamental force of interaction, with the change in the conception of spacetime of structural geometric property from the gravitational field, to the conception of spacetime structural geometric property of matter in motion. Spacetime is not a continent of matter (Substantialism) but rather is contained in (...) matter insofar as it constitutes the geometric structure that gives it its shape and allows its changes, to which as space it confers its ability to contain and as time its capacity to becoming. Nor is spacetime the category of geometric relations of material bodies and their events (Relationism), since it is not a relational property of matter but rather the geometric spacetime structural property of matter, which it endows with their abilities to self-contain and transform. The author's conception of spacetime is that dynamic energy-matter, geometrically endowed with the four dimensions of spacetime, is spatially self-contained and temporarily self-transforming. The wave-particle, of matter and of the field, does not exist in spacetime, but this is the intrinsic structural geometric property of the wave-particle, therefore, attached to its own internal nature, as its intrinsic dimensional geometric property which with the force of law is manifested in its quantitative measurements, either when the wave particle itself is taken or in relation to others. Thus, only theories on gravity from Quantum Gravity are possible, although they must be reformulated, renouncing to integrate them with the geometric vision derived from the equations of the so-called "General Relativity".

The author presents the history of gravitational waves according to Einstein, linking it to his biography and his time in order to understand it in his connection with the history of the Semites, the personality of Einstein in the handling of his conflict-generating circumstances in his relationships competition with his colleagues and in the formulation of the so-called general theory of relativity. We will fall back on the vicissitudes that Einstein experienced in the transition from his scientific work to normal (...) science as a pillar of theoretical physics. We will deal with how Einstein introduced the relativistic ether, conferring an "odor of materiality" to his geometric explanation of gravity, where undoubtedly it does not fit, but that he had to give in to the pressure that was justified by his most renowned colleagues, led by Lorentz. Einstein had to do it to stay in the queue that would lead him to the Nobel. It was thus, as developing the relativistic ether thread, in June 1916, he introduced the gravitational waves of which, in an act of personal liberation and scientific honesty, when he could, in 1938, he demonstrated how they could not exist, within the scenario of his relativity, to immediately also put an end to the relativistic ether.

Gravity is the curvature of spacetime, the structural property of static gravitational field, a geometric field, in curved coordinates, according the functions guv, that express geometric relations between material events. Course, general relativity is a relational theory, however, gravity, a thinking category, has symetric physical effects with matter. We use, analitic and critic method of reread the general relativity, since the perspective of the history of the science and the philosophy of the science. Our goal is driver the debate on (...) gravity, to the arena of the quantum physics, but without the ballast of the general relativity. We find that through of relativist aether was attempted transform spacetime in a substantia without succes, the consequence was return to problematic geometric field. The philosophy of the science intervenes, and according the best philosophical theory of substantivalism, spacetime is a inmaterial, geometric substantia. Then, the metaphysics arrives to a full solution in the super-substantivalism theory, that affirms: matter arises from geometric spacetime. Thus, it explains consistently the symetric physical effects between spacetime and matter. Surely, this solution is a medieval speculation. Our conclusion is that since general relativity do not defined physically spacetime leads necessarily to philosophical definitions of relationism and substantivalism on spacetime that are unacceptable physically. Therefore, gravity is not the curvature of spacetime. (shrink)

The General Relativity understands gravity like inertial movement of the free fall of the bodies in curved spacetime of Lorentz. The law of inertia of Newton would be particular case of the inertial movement of the bodies in the spacetime flat of Euclid. But, in the step, from general to particular, breaks the law of inertia of Galilei since recovers apparently the rectilinear uniform movement but not the repose state, unless the bodies have undergone their collapse, although, the curved spacetime (...) becomes flat and the curved geodesies becomes straight lines. For General Relativity is a natural law, within of a gravitational field, the accelerated movement of the bodies, that leads to that a geometric curvature puts out to the bodies in such geodesic movement. In this paper this error of General Relativity, like generalization of the law of inertia of Galilei, is examined and it is found that it is caused by suppression of mass and force that allows conceiving acceleration like property of spacetime. This is a mathematical and non-ontological result. Indeed, mass and force are the fundament that the gravitational acceleration is independent of the magnitude of mass of the bodies but gravity not of the mass and the gravitational force. The action of the gravity force, on inertial and gravitational masses of a body, produces mutual cancellation during its free fallen but too its weight when this cease. By means of the third law of Newton it shows that gravity is a force since weight is caused by gravity. (shrink)

While the philosophers of science discuss the General Relativity, the mathematical physicists do not question it. Therefore, there is a conflict. From the theoretical point view “the question of precisely what Einstein discovered remains unanswered, for we have no consensus over the exact nature of the theory 's foundations. Is this the theory that extends the relativity of motion from inertial motion to accelerated motion, as Einstein contended? Or is it just a theory that treats gravitation geometrically in the spacetime (...) setting?”. “The voices of dissent proclaim that Einstein was mistaken over the fundamental ideas of his own theory and that their basic principles are simply incompatible with this theory. Many newer texts make no mention of the principles Einstein listed as fundamental to his theory; they appear as neither axiom nor theorem. At best, they are recalled as ideas of purely historical importance in the theory's formation. The very name General Relativity is now routinely condemned as a misnomer and its use often zealously avoided in favour of, say , Einstein's theory of gravitation What has complicated an easy resolution of the debate are the alterations of Einstein's own position on the foundations of his theory”, (Norton, 1993). Of other hand from the mathematical point view the “General Relativity had been formulated as a messy set of partial differential equations in a single coordinate system. People were so pleased when they found a solution that they didn't care that it probably had no physical significance” (Hawking and Penrose, 1996). So, during a time, the declaration of quantum theorists:“I take the positivist viewpoint that a physical theory is just a mathematical model and that it is meaningless to ask whether it corresponds to reality. All that one can ask is that its predictions should be in agreement with observation.” (Hawking and Penrose, 1996)seemed to solve the problem, but recently achieved with the help of the tightly and collectively synchronized clocks in orbit frontally contradicts fundamental assumptions of the theory of Relativity. These observations are in disagree from predictions of the theory of Relativity. (Hatch, 2004a, 2004b, 2007). The mathematical model was developed first by Grossmann who presented it, in 1913, as the mathematical part of the Entwurf theory, still referred to a curved Minkowski spacetime. Einstein completed the mathematical model, in 1915, formulated for Riemann ́s spacetimes. In this paper, we present as of General Relativity currently remains only the mathematical model, darkened with the results of Hatch and, course, we conclude that a Einstein ́s gravity theory does not exist.

Desde un enfoque epistemológico se busca hacer la crítica de la relatividad general en el momento en que se formula una teoría cuántica sobre la gravedad (año 1967). Como consecuencia de la restauración de la concepción física sobre la geométrica de la gravedad, en una física de partículas-ondas, se plantea, mediante un análisis formal de estructura, que el gravitón-onda gravitatoria tendrá una velocidad mayor que c.

Spacetime and motion are interconnected concepts. A better understanding of motion leads to a better understanding of spacetime. We use the historical critical analysis of the various theoretical proposals on motion in search of clues ignored. The prediction of the general relativity that the motion occurs in the static gravitational field is not valid because the motion always occurs in a given medium as vacuum, atmosphere, water, etc. The concept of motion and the equations of the special and general relativity, (...) as the theory of Galilee-Newton reduce motion elements to particle and spacetime. In this paper, we present the medium (in special, the quantum vacuum), as the third essential element of motion, inseparable of spacetime since it is its material support of which the spacetime is its structural form, and we analyse its consequences in the theories of spacetime. Our contribution is declare, that the spacetime itself does not exist, or is a relational property of matter, but a structural property of matter. (shrink)

In addition, by means of the third law of Newton it demonstrates that gravity is a force since weight is caused by gravity force. (shrink)

When a theory, as the general relativity, linked to special relativity, is foundation of a scientific paradigm, through normal science and academy, scientifics, professionals, professors, students and journals of that scientific community, the paradigm, it self-sustains and reproduces. Thus, the research is obligated and limited to apply the model existent of the paradigm to formulate problems and solve them, without searching new discoveries. This self-protection of the paradigm causes it to end its cycle of life, only after a long time, (...) until that arise unresolved anomalies, some presents since origin, that they finally cause its change by other new paradigm. In this work, we study the most important anomalies that are part of the foundations of general relativity with the goal of promoting the call period of transition that is previous to scientific revolution. We use critical analysis method for rereading the general relativity, from the perspective of the history of science and philosophy of science. We find, the structural and complex anomaly of general relativity based on metaphysical spacetime that produces the metaphysics replaces physics. Also, two internal anomalies their direct consequences. These are: matter curves metaphysical spacetime, and metaphysical spacetime determines the geodesic motion of physical matter. We conclude that general relativity has no valid physical concept of spacetime, therefore of gravity. For these reasons, a new paradigm is needed. (shrink)

Con base en los varios papeles, 1989-2002, mediante los textos originales, se presenta la crítica, de los matemático-físicos A. Logunov y M. Mestvirishvil, de la “general relatividad” de A.

Se demuestra concluyentemente que desde las ecuaciones de Einstein-Grossman-Hilbert la gravedad es absurdamente un campo métrico carente de realidad física.

General Relativity defines gravity like the metric of a Lorentzian manifold. Einstein formulated spacetime as quality structural of gravity, i.e, circular definition between gravity and spacetime, also Einstein denoted "Space and time are modes by which we think, not conditions under which we live" and “We denote everything but the gravitational field as matter”, therefore, spacetime is nothing and gravity in first approximation an effect of coordinates, and definitely a geometric effect. The mathematical model generates quantitative predictions coincident in high (...) grade with observations without physical meaning. Philosophy intervened: in Substantivalism, spacetime exists in itself while in Relationalism as metrical relations. But, it does not know what spacetime. The outcomes of model have supported during a century, validity of the General Relativity, interpreted arbitrarily. Einstein formulated, from quadrupoles of energy, the formation of ripples in spacetime propagating as gravitational waves abandoned, in 1938, when he said that they do not exist. LIGO announced the first detection of gravitational waves from a pair of merging black holes. They truly are waves of quantum vacuum. (shrink)

Journal bearings play an important role on many rotating machines placed on industrial environments, especially in steam turbines of thermoelectric power plants. Babbitt damage (BD) and excessive clearance (C) are usual faults of steam turbine journal bearings. This paper is focused on achieving an effective identification of these faults through an intelligent recognition approach. The work was carried out through the processing of real data obtained from an industrial environment. In this work, a feature selection procedure was applied in order (...) to choose the features more suitable to identify the faults. This feature selection procedure was performed through the computation of typical testors, which allows working with both quantitative and qualitative features. The classification tasks were carried out by using Nearest Neighbors, Voting Algorithm, Naïve Associative Classifier and Assisted Classification for Imbalance Data techniques. Several performance measures were computed and used in order to assess the classification effectiveness. The achieved results (e.g., six performance measures were above 0.998) showed the convenience of applying pattern recognition techniques to the automatic identification of BD and C. (shrink)

Transdisciplinary research knits together knowledge from diverse epistemic communities in addressing social-environmental challenges, such as biodiversity loss, climate crises, food insecurity, and public health. This paper reflects on the roles of philosophy of science in transdisciplinary research while focusing on Indigenous and other subaltern forms of knowledge. We offer a critical assessment of demarcationist approaches in philosophy of science and outline a constructive alternative of transdisciplinary philosophy of science. While a demarcationist focus obscures the complex relations between epistemic communities, transdisciplinary (...) philosophy of science provides resources for meeting epistemic and political challenges of collaborative knowledge production.

In the standard model of cosmology, λCDM, were introduced to explain the anomalies of the orbital velocities of galaxies in clusters highest according estimated by General Relativity the dark matter and the accelerated expansion of the universe the dark energy. The model λCDM is based in the equations of the General Relativity that of the total mass-energy of the universe assigns 4.9% to matter (including only baryonic matter), 26.8%, to dark matter and 68.3% to dark energy adjusted according observed in (...) Planck mission, therefore, excluding bosonic matter (quantum vacuum). However, the composition of dark matter and dark energy are unknown. Due to that it lacks of a correct physical theory of gravity since General Relativity is only their powerful equations, which in their applications, their results are interpreted arbitrarily. Properties as curvature, viscous fluid, dragging frame and gravity action are attributed mistakenly to the spacetime by the materialist substantivalism, the most credible philosophical interpretation that complements the General Relativity, caused by its absence of physical definition of spacetime and static gravitational field as immaterial, but which violates, the conception of gravity as an effect of coordinates of the generalization of the inertial motion to the accelerated motion and, in particular, the description of the metric tensor of gravity as a geometric field. These properties are really of the quantum vacuum, the main existence form of the matter. In this paper we propose that the quantum vacuum is the source of dark matter and dark energy, therefore, the components of the quantum vacuum are of them. Both are opposite effects of the quantum vacuum that when gravitationally interacts with the cosmic structures, the vacuum it curves and when such interaction tends to cease by declination of the formation of these structures, occurring since near five milliard of years ago, vacuum it maintains quasi plane, since it interacts gravitationally very weakly with itself, accelerating expansion of the universe.

The theoretical contradiction between General Relativity and Quantum Gravity about gravity was ended, since spacetime is not structural property of the gravitational fi eld like Einstein said. Exactly spacetime is the structural geometric property of the matter and energy that it gives their geometric dimensions. Thus, spacetime is not continent of the matter (Substantialism), since it is contained. Neither is the category of the relations between material bodies or between their events (Relationalism) since is not relational property; spacetime is structural (...) property. The particle-wave, of matter and eld, has intrinsically three spatial dimensions and one temporal dimension. The spacetime is intrinsically the structural quality of particle-wave. The spacetime is the geometric dimensions of the particle-wave itself and for others. Therefore, the matter and its movements are containing itself. Now only Quantum Gravity is possible. (shrink)

A proposta é construir uma ponte de intersecção entre os pensamentos de Pareyson, Aristóteles e Platão, e, ancorando-a nos conceitos cunhados na Teoria da Formatividade, expor como o filósofo italiano relê as problemáticas colocadas pelos filósofos gregos antigos e de que maneira esta interseção de pensamentos e conceitos contribuem para a reflexão sobre Arte na atualidade e em particular para a análise da produção pictórica de Gerhard Richter.

Martha Nussbaum, filosofa e accademica statunitense, maestra del nostro tempo, attualmente docente di diritto ed etica all’Università di Chicago, è una pensatrice molto amata e dibattuta e autrice, insieme ad Amartya Sen, della celebre ‘teoria delle capacità’. Studiosa del mondo classico, esordisce con un’opera dal titolo ‘La fragilità del bene’, che la fa conoscere in tutto il mondo. Eppure, di questa docente e conferenziera di caratura mondiale, nel nostro Paese ancora non esistono opere che la riguardino, se non alcune tesi (...) di dottorato reperibili nel catalogo Opac online, comunque non destinate al vasto pubblico. […] Allora ho pensato che vi sia la necessità di spiegare in sintesi i concetti fondamentali della sua filosofia, racchiusa per lo più in volumi di grosso spessore, che, come tali, possono forse scoraggiare la lettura di chi non ha pazienza per addentrarsi in un pensiero tanto ricco, complesso e affascinante. Dalla lettura che ho fatto di quattro sue opere in versione integrale, “La fragilità del bene”, “Coltivare l’umanità”, “Non per profitto”, “Emozioni politiche”, è nato questo mio lavoro. (shrink)

L’indagine sugli anni giovanili di Benedetto Spinoza, filosofo poco compreso nel tempo in cui visse e colpito dalla scomunica della comunità ebraica nel 1656, a 24 anni, rivela una personalità già straordinariamente autonoma ed una forte indipendenza di pensiero. Dotato di una immensa cultura, comprensiva di molteplici riferimenti e tradizioni, Spinoza scopre e si avvicina anche alla filosofia di Cartesio, che lo affascina per la sua chiarezza logico-matematica ed il rigore che la caratterizza. La prima opera in cui egli si (...) cimenta si chiama, proprio, Principi di filosofia cartesiana, una lettura, migliorata in chiave di ricostruttivismo logico, del testo cartesiano. In questo documentatissimo e agile libro si ripercorre la fase giovanile della vita del filosofo olandese: l’ambiente religioso, gli studi, l’intraprendenza commerciale dell’Olanda del Seicento, il desiderio di solitudine per compiere le sue ricerche, l’aspirazione ad una vita tranquilla e l’amore per la verità, ma anche le frequentazioni con le sette religiose del suo tempo e la fitta rete di contatti e corrispondenze che Spinoza intrattenne con diversi intellettuali europei, fino all’offerta di una cattedra universitaria che gli arriva nel 1673, dieci anni dopo la pubblicazione dei Principi, grazie ad una traduzione fattane da Pieter Balling. Il successivo distacco da Cartesio porterà Spinoza ad elaborare un proprio originale sistema e gli consentirà di sviluppare l’idea del Deus sive Natura. (shrink)

In a recent paper, Gow raised a new and interesting problem for externalist representationalism, the conclusion of which is that its proponents are unable to provide an acceptable account of the phenomenal character of colour hallucination. In contrast to Gow, we do not believe that the problem is particularly severe – indeed, that there is any problem at all. Thus our aim is to defend externalist representationalism against the problem raised by Gow. To this end, we will first reconstruct her (...) reasoning, and then show that it poses no real challenge to externalist representationalism. (shrink)
