The causal characters (spacelike, lightlike, timelike) of the coordinate lines, coordinate surfaces and coordinate hypersurfaces of a coordinate system in Relativity define what is called its causal class. It is known that, in any relativistic space-time, there exist one hundred and ninety nine such causal classes. But in Newtonian physics (where only spacelike and timelike characters exist) the corresponding causal classes have not been discussed until recently. Here it is shown that, in sharp contrast with the relativistic case, in Newtonian (...) space-time the different causal classes of coordinate systems are drastically reduced to four. These causal classes admit simple geometric descriptions and physical interpretations. For example, it is shown that one can generate coordinate systems of the four causal classes by means of the sole linear synchronization group, i.e. by coordinate transformations that only change the origin of time linearly. The relativistic analogs of these examples are also considered. (shrink)

En el presente artículo se analiza la noción de nostalgia de futuro para comprender su significado en el contexto de la filosofía transhumanista y en el de la filosofía de Leonardo Polo. Se ha elegido como representantes del transhumanismo a los que históricamente son sus padres intelectuales: Julian Huxley y Fereidoun M. Esfandiary, quien más tarde cambió su nombre a FM-2030. El objetivo del artículo es analizar las dos filosofías para profundizar en el deseo de trascendencia que cada una desarrolla (...) y ver hasta qué punto es posible un diálogo entre ambas. (shrink)

La palabra cultura tiene, por lo menos, un doble sentido, uno primario y otro suplementario. El primero hace referencia a habilidades básicas y el segundo a destrezas adquiridas. El presente trabajo se ocupa de la cultura en el primer sentido, de la cultura que adquirimos con sólo nacer y criarnos en un determinado medio humano, en el medio particular donde nos hacemos individuos y capacitamos como personas. Existe un derecho a la cultura propia. Los Estados amparan las culturas con las (...) que se identifican y, por lo tanto, el derecho a las mismas de las gentes individuadas y socializadas gracias a ellas, al tiempo que han podido perfectamente acometer políticas genocidas con el resto. He ahí en definitiva la razón esquizofrénica por la que un derecho tan esencial como el derecho a la cultura propia no se ha cualificado hasta hoy como derecho humano. El problema no es la falta de algún derecho que debiera añadirse, sino la articulación del conjunto de los derechos humanos y, particularmente, los de carácter individual con los colectivos. Es un problema que no se plantea con los derechos humanos en sí, sino con el actual orden internacional y su correspondiente filosofía. (shrink)

The Great Palace of Constantinople has been subject to several investigations since the second half of the nineteenth century. All of them have been mostly concerned with the topographical, architectural and typological development of the imperial residence, leaving aside questions such as toponymics. This paper will deal with this issue taking into consideration the name of the complex of buildings that once was the core of the Constantinian Palace, the Daphne. Doing so, we will better understand the denomination of the (...) Palace, and shed light on the functions related to several spaces, the courtly ritual and, in short, the representation of power through architecture in an imperial context. Besides, the present enquiry will challenge some topographical assumptions on the complex. (shrink)

I propose that, in addition to the commonly recognized increase of entropy, two more time arrows influence living beings. The increase of damage reactions, which produce aging and genetic variation, and the decrease of the rate of entropy production involved in natural selection are neglected arrows of time. Although based on the statistical theory of the arrow of time, they are distinguishable from the general arrow of the increase of entropy. Physiology under healthy conditions only obeys the increase of entropy (...) arrow. But aging, death, and evolution are determined by the other time arrows as well. Paradoxes emerge from conflicts among the specific determinisms associated with each arrow. These conflicts, along with uncertainties intrinsic to the low-number statistics of the arrows of damage reactions and decrease of the rate of production of entropy, highlight the limits of determinism at different levels of biology and its dependence on time span and number of organisms. The recognition of the three time arrows opens new perspectives for the problem of compatibility of the flow of time in physics and psychology. (shrink)

El objeto del presente artículo es el estudio y comparación del transhumanismo de Julian Huxley y del trasumanar de Dante Alighieri. Aunque sean autores separados en el tiempo, están conectados por el hecho de que el trasumanar de Dante inspiró la formulación de la palabra con la que Huxley definió su filosofía, el transhumanismo. De este modo, se recorre a lo largo del artículo el pensamiento de Dante hasta llegar, después, al de Huxley con el objetivo de compararlos y comprobar (...) el alcance antropológico de ambas propuestas filosóficas.

Las actividades de fomento de la cultura científica se han convertido en una práctica habitual de las instituciones de investigación, que destinan presupuesto y recursos humanos a este objetivo. Cada vez más personal científico y técnico incorpora esta misión a sus tradicionales tareas de investigación y formación. Sin embargo, mientras la investigación y la docencia cuentan con indicadores establecidos, las actividades de divulgación siguen estando consideradas como un ejercicio extraordinario, pocas veces reconocido institucionalmente. En este sentido, el uso de unos (...) indicadores de cultura científica contribuiría a favorecer un cambio de mentalidad y a la obtención de datos objetivos sobre los que orientar las acciones de comunicación social de la ciencia. En este contexto, el Consejo Superior de Investigaciones Científicas (CSIC), a través de su Vicepresidencia Adjunta de Cultura Científica, se ha propuesto analizar las actividades desarrolladas en esta línea, entre 2011 y 2019, en relación a los siguientes indicadores: 1) la inversión económica; 2) el personal dedicado a cultura científica; 3) el número y tipo de actividades; y 4) el público al que se llega. Entre las principales conclusiones, destaca que el CSIC cuenta con una masa crítica más o menos estable de unas 200 personas que se dedican a tareas de cultura científica. Cada año se realizan alrededor de 15.000 actividades (presenciales y no presenciales) en las que se implican alrededor de 3.000 trabajadoras y trabajadores del CSIC. Cada año participan cerca de un millón y medio de personas de manera presencial. (shrink)

A noção de pessoa, para Simone Weil, passa por uma certa desconstrução e releitura que a filósofa realiza a partir da categoria do impessoal. Abordaremos inicialmente os conceitos de direito e obrigação, refletindo sobre as necessidades da alma pensadas por Weil, em que a obrigação abre o ser humano para o impessoal da pessoa, que por sua vez é conexo com o sentido do eterno e do sagrado. Neste escrito pretende-se resgatar alguns traços desta reflexão e destacar a relação entre (...) o impessoal com o eterno e o sagrado, enquanto constitutivos do ser humano, estudando como a partir do impessoal emerge uma nova percepção da relação ética.

“Posthumano” se ha convertido en un término paraguas para referirse a una variedad de movimientos y escuelas de pensamiento diferentes, incluyendo el posthumanismo filosófico, cultural y crítico; el transhumanismo (en sus variantes de extropianismo, transhumanismo liberal y democrático, entre otras); el enfoque feminista de los nuevos materialismos; el paisaje heterogéneo del antihumanismo, metahumanismo, metahumanidades y posthumanidades. Este uso genérico y global del término ha creado confusión metodológica y teórica entre expertos y no expertos. Este ensayo explorará las diferencias entre estos (...) movimientos, centrándose en particular en las áreas de significación que comparten el posthumanismo y el transhumanismo. Al presentar estas dos filosofías independientes, aunque relacionadas, el posthumanismo puede resultar un punto de vista más completo para reflexionar sobre posibles futuros. (shrink)

This title is a book of three richly detailed treatments of the myth of Kore. Kore, also called Persephone and referred to poetically by the Greeks as 'the unspeakable girl', was the daughter of Dermeter and Zeus who was abducted by Hades and made queen of the netherworld.

In the context of Posthuman Studies, attention towards education is gaining increasing significance to address the anthropocentric axioms embedded in contemporary worldviews. What is posthumanist education? This paper addresses this question affirming the importance of embodying posthumanist theory in practice. Attention will be dedicated to three original keywords: selves-care; flex(st)ability; commUnity. They will be investigated as possible posthumanist focuses to respond to current educational needs. This paper is not purely theoretical; it is anchored in material experiences that are being explored (...) by posthuman communities worldwide. We will reflect, more specifically, on the Posthuman Summer Camp, a collaborative event organized by the Italian Posthuman Network (Italy, August 10–13 2023). In this essay, the realities and possibilities that emerged during the first edition of the Camp are embraced as embodied and embedded, experiential and experimental – clearly, existential – praxes, enlightening our vision quest on posthumanist education.

A tendência de algumas visões naturalistas de deduzir o sentido da ação humana da sua natureza biológica conduz a naturalizar a violência como fenômeno político inexorável. A violência naturalizada leva a sociedade para a dinâmica da inexorável violência, cuja única solução é a legitimação de uma violência total. Propomos, neste ensaio, a desconstrução crítica dos determinismos naturalistas por meio da análise da ação humana e da especificidade de sua potência que se manifesta como potência criadora (Cornelius Castoriadis) e potência do (...) não (Giorgio Agamben). A potência da ação humana transcende os determinismos da sua natureza biológica, embora por eles esteja condicionada. The tendency some naturalist visions have to deduce the meaning of human action from their biological nature, leads to a naturalization of violence as an inexorable political phenomenon. Naturalized violence leads the society towards the dynamics of inexorable violence, whose only solution is legitimazing total violence. In this article we propose the critical deconstruction of naturalistic determinism by means of the analysis of human action and the specificity of its power, which is manifested as creative power (Cornelius Castoriadis) and power of no (Giorgio Agamben). The power of human action transcends the biological determinisms of its biologic nature, although the power of human action is conditioned by them. (shrink)

This essay defends that mimesis is an inherently agonistic and paradoxical human practice. The divergent views on mimesis by Plato and Aristotle, as well as by Adorno and Benjamin, are the philosophical manifestation of an agonistic tension of human mimesis that is not resolved in the exclusive truth of one of the positions, but remains as a permanent possibility to create alternative paths in history.

A sacralidade da vida humana tornou-se um problema filosófico com desdobramentos éticos e políticos. Este ensaio apresenta uma arqueologia da sacralidade a partir dos estudos de Walter Benjamin e Giorgio Agamben, estabelecendo uma comparação com o sentido da sacralidade nas polis antigas. A sacralidade aparece como figura simbólica marcada pelo paradoxo – ao mesmo tempo que protege a vida pelo direito sagrado, o direito a captura e a ameaça com a exceção. Porém, o paradoxo é insuperável, já que constitui o (...) modo de ser do humano. (shrink)

From the earliest days of its history, Brazil has been a favoured ‘laboratory’ for ethnic, cultural and religious hybridization. The absence or scarcity of white women and the temptations of sexual exoticism drove the Portuguese discoverers, and with them sailors from Normandy, Brittany and Poitou, to have relations with Indian women they chanced to meet, thus creating a race of coloured people, oddly called mamelucos, later cabocles (of mixed white and Indian ethnicity). Afterwards, the very substantial recourse to the Negro (...) slave trade and to manpower of African slave origin because of the requirements of the sugarcane economy (which remained predominant for a long time, especially in the Nordeste region of Bahia and Pernambuco), as well as the numerical imbalance of the sexes, characterized by a great predominance of men, popularized concubinage - all the more so because the Catholic Church was extremely reluctant to sanction interethnic unions with the sacrament of marriage. The Jesuits even recommended the despatch of white prostitutes or women condemned by common law (degredadas), for whom Brazil would furnish the opportunity for redemption, in order to avoid or reduce the number of unions of this kind. Thus, concubinage was the most common vehicle of miscegenation in Brazil. (shrink)

Audioscan Milano explores the strategies and experiments in the field of sound and noise of Milan’s legendary Studio di Fonologia Musicale. A multimedia installation composed of hundreds of field recordings of the city of Milan, Audioscan Milano provides its audience with a multisensory experience of the urban soundscape and the opportunity to interact with it digitally. The manipulation of noise and its transformation into musical sound via sophisticated electronic equipment emulates the Studio’s audio techniques but also exposes the reasons behind (...) its failure to attract a wider audience. Visitors to Audioscan Milano expect to hear urban noise rather than musical sounds and, despite some enthusiasm around being able to mix sound objects on the map and move them around the room, they fail to appreciate the technical subtleties of the procedures behind the music. Ultimately, Audioscan Milano constitutes an important link to Italy’s musical heritage of the 1950s and 1960s and can learn from its limitations, particularly when it comes to engaging the audience to play a more active role in the auditory experience of the city.
