Abstract: Using a critical review of the literature, we study a challenge from philosophical anarchism to J. Raz's theory of legal authority: it would be irrational to follow an order with which one disagrees, since it would mean acting against what is considered more justified. Through references from decision theory and epistemology, and deploying examples about tools for assisting in routine decision-making, we sketch two possible answers: first, it may be justifiable to put yourself in a situation that leads to (...) irrationally acting; second, according to the “blindspots” theory, we outline some restrictions from a theory of rationality to the authority.

L’auteur présente trois témoignages. Le premier montre l’influence que la figure de frère Charles de Jésus a exercée sur lui et sur ceux qui l’ont accompagné en pèlerinage. Le second explique pourquoi, aux yeux de l’auteur, le Père de Foucauld peut être considéré comme un martyr de la foi et de la charité. Le troisième raconte comment, mettant ses pas dans les pas de frère Charles, l’auteur a passé presque deux ans dans un ermitage, sur l’Assekrem, dans le Hoggar. (...) C’est là qu’est née l’intuition fondatrice des Fraternités Monastiques de Jérusalem. (shrink)

Esports have transformed playing video games into a competitive activity that bears similarities to sports and the processes of sportization. Taking as a starting point the concept of sports as competitive games, the objective of this work is to analyse the sportization of esports, as well as the impact of esports on the concept of sports and their implications on sports in the immediate future. Sports and esports are two different realities that interact with each other. This is a conceptual (...) problem for sports, and it also defines a practical challenge in the immediate future of sports. The virtual environment offers new possibilities in sports, such as broadening the possibilities of confrontation and competition development, contributing to reducing the environmental impact of certain sports, improving safety and maintaining the physical integrity of athletes, and increasing social justice and equality of chances in sports competitions. The challenge, therefore, is to try to bring esports and sports closer together, even moving toward hybrid sports, as addressed throughout this article. (shrink)

After Lavoisier's execution, the leading French chemists were Antoine-François Fourcroy , Louis-Bernard Guyton de Morveau and Claude-Louis Berthollet . At the beginning of the nineteenth century, Berthollet introduced a new conception of chemical change that challenged the theory of elective affinities which had dominated chemistry for nearly a hundred years. Berthollet's new affinities raised controversy among chemists and had to coexist with the firmly established theory of elective affinities. Apart from the public debate in research articles, Berthollet's affinities also had (...) to compete with the influence of Fourcroy and his school in the textbook market. This paper seeks to assess the extent to which French textbooks published at the beginning of the nineteenth century were committed to Berthollet's innovation, and how they contributed to its marginalization.

O artigo procura argumentar contra a ideia de que a filosofia da história de Kant contaria com dois modelos de fundamentação: um modelo oficial, de natureza hipotético-teleológica, e outro hermenêutico-explicativo, que, porém, acabaria por implodir o sistema. Trata-se de mostrar que há um único modelo, de natureza hermenêutica-explicativa, que não obstante faz uso de princípios hipotético-teleológicos. Mais ainda, que tal modelo está presente ao longo de diversos momentos do sistema, como na Doutrina do Direito , ou na Religião nos limites (...) da simples razão . The article argues against the idea that Kant's philosophy of history would have included two types of foundation: an official model, hypothetical and teleological in nature, and other hermeneutic-explanatory, the last one that eventually would implode the system. The aim is to show that there is a single model, of hermeneutics-explanatory nature, which nevertheless makes use of hypothetical and teleological principles, and that such a model is present at various moments throughout the system, as in the Doctrine of Right , or in the Religion within the limits of pure reason.

This paper publishes for the first time 132 conjectures by Nicolaus Heinsius on Ovid’s Metamorphoses 1‒4. The value and possible motivations of each proposal are briefly assessed.

Classical propositional logic plays a prominent role in industrial applications, and yet the complexity of this logic is presumed to be non-feasible. Tractable systems such as depth-bounded boolean logics approximate classical logic and can be seen as a model for resource-bounded agents whose reasoning style is nonetheless classical. In this paper we first study a hierarchy of tractable logics that is not defined by depth. Then we extend it into a modal logic where modalities make explicit the assumptions discharged in (...) propositional proofs, thereby expressing blueprints for proofs. A natural deduction system is provided that permits to reason about and manage such proof blueprints. (shrink)

Lately, nanotechnology has become one of the main topics in the debates regarding what has been called the _Next Industrial Revolution_ within what are known as _emergent technologies_. This paper contains a comparative analysis of the different philosophical groundings, arguments and principles invoked in the official ethical approaches proposed by each of two of the main Western communities. By _official ethical approaches_ or _official positions_ we mean the opinions officially expressed by the government institutions about how ethical considerations prompted by (...) nanotechnologies should be tackled. The analysis is based, then, on the official points of view, expressed through two documents, namely two official releases issued by governmental offices or institutions in both communities, Europe and the United States of America, and considered by the authors as representative of the official opinions of the governmental institutions in each society.

Planear una "estética plural de la naturaleza" es darle a la obviedad del enunciado que se trata de explorar algo parecido a un impulso haciéndolo avanzar por el camino de la complejidad. Esto en primer lugar. Después, hay que pararse a pensar que la articulación de estos términos, arte y naturaleza, no sólo implica enlazar la actividad relativa al primero con una imagen o arsenal de imágenes en las que esta segunda se representaría; también es vincularla a un concepto que (...) la significa. ¿Cuál? Lógicamente, la imitación, la mímesis. Aunque dadas las variaciones que ha sufrido dicho concepto a lo largo de la historia, parece necesario valorar la necesidad de comprender su objeto, la naturaleza, en lo que llamaría su dinamismo temporal. En otras palabras, habría que intentar una "historia de la naturaleza", cuya oportunidad aconsejaría mantenerla en paralelo con la "historia del arte". Y si este paralelismo -desde luego estético- del arte y la naturaleza implica en sus respectivas trayectorias temporales aquella parte de la reflexión estética que explora cada momento histórico con una atención especial en el "arte como mímesis", entonces el objetivo de dicha reflexión será también la naturaleza, que toca ir a buscar allí donde se encuentra efectivamente: en el pensamiento de la época. Tendríamos así los términos Arte, Naturaleza, Mímesis. Y de este último, la Mímesis, ya sabemos que no es la representación fiel de entidades o configuraciones naturales. ¿Qué es entonces? La proyección en una obra de Arte de unos contenidos mentales que tienen por objeto la Naturaleza. Quedan vinculados así los tres términos barajados en este libro. (shrink)

The Einstein–Podolsky–Rosen paradox (1935) is reexamined in the light of Shannon’s information theory (1984). The EPR argument did not take into account that the observer’s information was localized, like any other physical object.
