Thomas S. Kuhn acuno la expresion tension esencial para aludir al conflicto entre las tendencias conservadora y revolucionaria en la ciencia. Estas dan lugar respectivamente a la ciencia normal, que trata de salvar al paradigma dominante de las refutaciones, y a la extraordinaria, que responde a las dificultades sustituyendo las viejas teorias por otras radicalmente novedosas. La actitud adoptada en cada momento no esta dictada por normas de racionalidad, sino por la psicologia y la sociologia de los cientificos y sus (...) comunidades. Al conceder una funcion central a la psicosociologia en la explicacion del desarrollo cientifico, Kuhn creo la alta tension hoy omnipresente entre racionalidad e irracionalidad, objetividad y subjetividad, universalismo y relativismo, realismo e idealismo. Este homenaje a la obra de Kuhn recoge diversas contribuciones a las principales caras de esta tension, desde la perspectiva de la filosofia, la sociologia, la psicologia y la historia de la ciencia.

Para Galileo la Naturaleza tenía estructura geométrica. El atomismo veía los sistemas físicos como estructuras matemáticas; pero el atomismo es discontinuo y las magnitudes, continuas. Para unificar física y matemáticas, compuso la materia de átomos inextensos y las magnitudes continuas de infinitos elementos indivisibles, lo que planteó problemas físicos y matemáticos irresolubles pero estimulantes.

Brahe creía que su teoría sobre los cometas refutaba el copernicanismo. Analizamos el argumento y mostramos que ningún sistema existente podía acomodarlos. Tras el decreto anticopernicano de 1616, muchos jesuitas que rechazaban a Ptolomeo e incluso coqueteaban con Copérnico se vieron obligados a abrazar el sistema de Brahe. La discusión de los cometas de 1618 permitía a los jesuitas reforzar a Brahe en un momento en que Galileo no podía defender el copernicanismo. La disputa de los cometas se examina bajo (...) esta luz y se conjetura la orientación pro-Brahe de las censuras del Diálogo de Galileo.It was Brahe’s belief that the motion of comets refuted Copernicus’ system and complied with his own. His argument is analyzed to show that neither could explain their motion. After the anti-copernican decree of1616 quite a few Jesuits that rejected Ptolemy and even courted Copernicus were bound to accept Brahe’s system. The appearance of comets in 1618 allowed the Jesuits to describe them and support Brahe, while Galileo could not treat them in copernican terms. So he crossed them off. The comets war is seen under this light and the pro-Brahe bias in the censorship of the Dialogo is strongly conjectured. (shrink)

El tema de la hospitalidad fue suficientemente analizado por Jacques Derrida, el pensador francés de la deconstrucción. Este artículo busca investigar la cuestión de la hospitalidad considerando la oposición radical, la aporía, entre la ley de la hospitalidad incondicional, en su singularidad universal, y las leyes de la hospitalidad condicional. ¿Quién se encuentra apto para la hospitalidad? ¿Alguien que dice su nombre? ¿Una sujeto de derecho? ¿Un extranjero? Exploraremos algunas de las condiciones para responder a esta pregunta: la hospitalidad como (...) un asunto del lugar, como un asunto del lenguaje y como un asunto del nombre. (shrink)

Background: COVID-19 has taken many lives worldwide and due to this, millions of persons are in grief. When the grief process lasts longer than 6 months, the person is in risk of developing Complicated Grief Disorder. The CGD is related to serious health consequences. To reduce the probability of developing CGD a preventive intervention could be applied. In developing countries like Mexico, the psychological services are scarce, self-applied interventions could provide support to solve this problem and reduce the health impact (...) even after the pandemic has already finished.Aims: To design and implement a self-applied intervention composed of 12 modules focused on the decrease of the risk of developing CGD, and increasing the life quality, and as a secondary objective to reduce the symptomatology of anxiety, depression, and increase of sleep quality. The Intervention Duelo COVID follows the principles of User Experience and is designed according to the needs and desires of a sample of the objective participants, to increase the adherence to the self-applied intervention, considered one of the main weaknesses of online interventions.Methods: A Randomized Controlled Trial will be conducted from the 22nd of December of 2020 to the first of June 2021. The participants will be assigned to an intervention with elements of Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, Mindfulness and Positive Psychology. The control group will be a wait-list condition, that will receive the intervention 1.5–2 months after the pre-measurement were taken. The Power Size Calculation conducted through G*Power indicated the need for a total of 42 participants, which will be divided by 21 participants in each group. The platform will be delivered through responsive design assuring with this that the intervention will adapt to the screen size of cellphones, tablets, and computers.Ethics and Dissemination: The study counts with the approval of the Research Ethics Committee of the Autonomous University of Ciudad Juárez, México, and it is registered in Clinical Trials. The article is sent and registered in clinical trials before the recruitment started. The results will be reported in future conferences, scientific publications, and media. (shrink)

El presente texto busca reflexionar en torno al mundo de las prácticas del cuerpo y su vínculo con cierto tipo de culturas juveniles que poseen como forma de vida la alteración corporal, y donde en la actualidad se puede observar –en nuestro país– una explosión de la experimentación con el tatuaje y con el piercing, y de manera más incipiente –pero también significativa– con los implantes, las escarificaciones, los branding, las expansiones y la variante de las suspensiones humanas; práctica sobre (...) la cual el artículo profundiza intentando dar cuenta del contexto social y cultural donde surge la suspensión humana; los procesos de apropiación que experimenta esta práctica a partir de la irrupción de culturas juveniles en las sociedades contemporáneas; los significados y procedimientos asociados a este ritual; y los nexos entre política, estética y modificación corporal.

This paper extends earlier work by its authors on formal aspects of the processes of contracting a theory to eliminate a proposition and revising a theory to introduce a proposition. In the course of the earlier work, Gardenfors developed general postulates of a more or less equational nature for such processes, whilst Alchourron and Makinson studied the particular case of contraction functions that are maximal, in the sense of yielding a maximal subset of the theory (or alternatively, of one of (...) its axiomatic bases), that fails to imply the proposition being eliminated. In the present paper, the authors study a broader class, including contraction functions that may be less than maximal. Specifically, they investigate "partial meet contraction functions", which are defined to yield the intersection of some nonempty family of maximal subsets of the theory that fail to imply the proposition being eliminated. Basic properties of these functions are established: it is shown in particular that they satisfy the Gardenfors postulates, and moreover that they are sufficiently general to provide a representation theorem for those postulates. Some special classes of partial meet contraction functions, notably those that are "relational" and "transitively relational", are studied in detail, and their connections with certain "supplementary postulates" of Gardenfors investigated, with a further representation theorem established.

La búsqueda de una educación ambiental basada en los principios de la sustentabilidad, está en el centro de la reflexión de la autora. El arte de educar implica, por parte de educadores y educandos, consiste en asumirse como seres sociales y complejos; inmersos en una realidad que exige un compromiso constante con el medioambiente. La libertad que podemos alcanzar en el mundo exterior -el cual habitamos en tanto cuerpos interrelacionados entre sí y respecto de su medio- tiene como requisito previo (...) el desarrollo de nuestra libertad interna. La propuesta implica una educación ambiental como proceso crítico de comunicación y reelaboración constante del conocimiento, donde se construyen realidades sobre la base de la paz y de un futuro compartido.

Este artículo reflexiona sobre algunas facetas de la descalificación al pensamiento libre, en paralelo a las inequidades de género. Se ejemplifica con la persecución a mujeres en distintas épocas a las que el poder destruyó, de un modo análogo a como la codicia del poder destruye la naturaleza. Realza el artículo la existencia de una diversidad de saberes, para los que se requieren puertas abiertas, superando los cerrojos excluyentes, cruzando los muros de la inequidad de género, de las injusticias sociales (...) y de los atropellos por razones étnicas y otras, y las actitudes destructoras de la naturaleza y de las culturas.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, Rovelli examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 21-year-old Werner Heisenberg first developed quantum theory, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be (...) magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercly debate the theory's meaning, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships, not substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for understanding the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better understand our place in it. (shrink)

In this article, Carlos Pereda introduces the concept of “colonial reason” and explores how philosophical practices and modes of thought are entwined with colonial political structures of exploitation, exclusion, and oppression. Pereda argues that philosophy in Latin America risks perpetuating and reinforcing the colonial gesture, either by turning to the European centers of thought (thus pursuing debates that always take place elsewhere) or by isolating itself and idealising the “own.” According to Pereda, both approaches fail to dismantle colonial violence (...) within philosophy. In his alternative approach, Pereda outlines principles and methodological criteria for the decolonisation of reason and philosophy. He emphasises the importance of methodological prudence that discerns between innocent, paralysing, and strategic uses of identity expressions and advocates for modes of reading and argumentation that conceive philosophy as an inclusive and ongoing dialogue. In Pereda’s terminology, this entails fostering “permeable reason” that manifests itself through “nomadic thinking,” a form of thinking that is capable of questioning itself and being questioned.

Many of the computing systems programmed using Machine Learning are opaque: it is difficult to know why they do what they do or how they work. Explainable Artificial Intelligence aims to develop analytic techniques that render opaque computing systems transparent, but lacks a normative framework with which to evaluate these techniques’ explanatory successes. The aim of the present discussion is to develop such a framework, paying particular attention to different stakeholders’ distinct explanatory requirements. Building on an analysis of “opacity” from (...) philosophy of science, this framework is modeled after accounts of explanation in cognitive science. The framework distinguishes between the explanation-seeking questions that are likely to be asked by different stakeholders, and specifies the general ways in which these questions should be answered so as to allow these stakeholders to perform their roles in the Machine Learning ecosystem. By applying the normative framework to recently developed techniques such as input heatmapping, feature-detector visualization, and diagnostic classification, it is possible to determine whether and to what extent techniques from Explainable Artificial Intelligence can be used to render opaque computing systems transparent and, thus, whether they can be used to solve the Black Box Problem.

Edmund Husserl’s engagement with Bertrand Russell’s paradox stands in a continuum of reciprocal reception and discussions about impossible objects in the School of Brentano. Against this broader context, we will focus on Husserl’s discussion of Russell’s paradox in his manuscript A I 35α from 1912. This highly interesting and revealing manuscript has unfortunately remained unpublished, which probably explains the scant attention it has received. I will examine Husserl’s approach in A I 35α by relating it to earlier discussions of relevant (...) topics in his manuscripts and the broader historical context of the School of Brentano and early phenomenology.

La percepción de la vida se vincula a la actitud ante la muerte para abrirse a la experiencia estética en torno al Poema de Mio Cid y a las Coplas de Manrique. Los horizontes simbólicos que brotan de la épica y de la lírica acentúan la figura trágica del héroe, del caballero.

This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)
