This book provides an up-to-date overview of the foundations of spacetime physics. It features original essays written by world-class experts in the physics and philosophy of spacetime. The foundational questions regarding the origin and nature of spacetime are branching into new and exciting directions. These questions are not restricted to the quantum gravity program but also arise in the context of a well-established theory like general relativity. Against the background of these quick and diverse developments, this volume features a broad (...) range of perspectives on spacetime. Part I focuses on the nature of spacetime in non-quantum theories, such as Newtonian mechanics and relativity. Part II explores some intriguing conceptual implications of developing a quantum theory of spacetime. The Foundations of Spacetime Physics is an essential resource for scholars and advanced students working in philosophy of physics, philosophy of science, and scientific metaphysics. (shrink)

En la Psicología, las emociones que más se han estudiado son las emociones negativas, llamadas así porque generan una experiencia desagradable. Las más importantes son la ansiedad (ante situaciones de amenaza), la ira o enfado (ante un daño o perjuicio), y la tristeza (precursora de la depresión, se produce ante situaciones de pérdida).

The beliefs of the agents in a multi-agent system have been formally modelled in the last decades using doxastic logics. The possible worlds model and its associated Kripke semantics provide an intuitive semantics for these logics, but they commit us to model agents that are logically omniscient. We propose a way of avoiding this problem, using a new kind of entities called subjective situations. We define a new doxastic logic based on these entities and we show how the belief operators (...) have some desirable properties, while avoiding logical omniscience. A comparison with two well-known proposals (Levesque's logic of explicit and implicit beliefs and Thijsse's hybrid sieve systems) is also provided. (shrink)

Tradicionalmente, las primas de los contratos de seguros se han considerado justas o equitativas cuando se corresponden exactamente con el riesgo de las pólizas, medido este último mediante la esperanza matemática de la siniestralidad. En este artículo llevamos a cabo una crítica de este enfoque aparentemente objetivo y proponemos una justificación alternativa de la denominada equidad actuarial, basada en argumentos contractualistas. Para ello nos apoyamos en ciertas intuiciones de Jean Domat, un jurista francés del siglo XVII, acerca de la incertidumbre (...) compartida, integradas dentro del marco general proporcionado por la teoría contractualista del economista y filósofo contemporáneo Robert Sugden.

Este artículo presenta una alternativa a la dicotomía entre razones motivacionales y razones normativas. En Practical Reality, Dancy mantiene que ambas razones se identifican con estados externos al agente--"tesis de la identidad" --. Hay dos argumentos en PR a favor de la TI: El primero se basa en una interpretación externista del significado de "tener una razón". El segundo presenta una vía indirecta, defendiendo que las adscripciones de razones según estados psicológicos internos no son casos centrales en las explicaciones normativas. (...) Estas dos críticas ignorarían una fuerte intuición normativa: el "acceso epistémico". Si ésta es persuasiva, los estados internos no pueden ser eliminables. /// This paper presents an alternative account to the dichotomy between normative and motivating reasons. In Practical Reality, Dancy argues that both types of reasons should be identified with external states of the agent--"identity thesis". There are two arguments in PR for the IT: one is based on an externalist interpretation of expressions like "A has a reason to x". The other is an indirect argument that claims that the ascription of reasons grounded on internal states cannot be central instances in normative explanations. Both arguments ignore a strong intuition: the "epistemic access". If this is a persuasive intuition, internal psychological states cannot be eliminated. (shrink)

The necessary starting point in an analysis of Yugoslavia is the level of development of self-management. The 1973 law on collective work, the goal of which was to contain growing technocratic tendencies in the enterprises, has disciplined the powers of the “work units,” the democratic cells which are directed from below (in practice, they are something similar to department assemblies) and which were supposed to provide the most authentic foundation for self-management. These productive units can be compared to Western capitalist (...) firms whose goal, as we know, it to strengthen control over production costs, increase economic efficiency, facilitate management and create a more congenial atmosphere for work.

En nuestra sociedad de Post Dictadura, la temática del cuerpo, su expresión y exploración más allá de los cánones impuestos por la normatividad, constituyen un tema pendiente que -cuando emerge- genera des-orden, instalando la pregunta por los límites y consensos sobre nuestro orden social y cultural. Es así como las experiencias que incorporan la dimensión subjetiva del cuerpo como son el uso de drogas y la sexualidad entre otras, y que se sitúan desde lo orgiástico y festivo, son negadas, ..

El objetivo de este estudio consiste en identificar los vínculos y afectos que el alumnado establece con los bienes patrimoniales cercanos y explorar cómo tales relaciones pueden resultar útiles para ensayar una Educación Patrimonial para una ciudadanía crítica y democrática, a partir de la presencia de la memoria (histórica y democrática) en sus elecciones. En el contexto de una experiencia educativa en el Grado de Educación Primaria de la Universidad de Granada, se solicitó a un grupo de estudiantes que escogiera (...) un bien patrimonial personal y estableciera una breve narración autobiográfica. El trabajo adopta un enfoque cualitativo, de carácter exploratorio y descriptivo-interpretativo. Los resultados muestran que un conjunto significativo de narraciones se asocia al ámbito de los conflictos y los acontecimientos conflictivos de carácter histórico, es decir: introducen la memoria, los afectos y vínculos de la esfera familiar en el ámbito más amplio de la memoria histórica y democrática.

In this paper six of the most important issues in the philosophy of logic are examined from a standpoint that rejects the First Commandment of empiricist analytic philosophy, namely, Ockham’s razor. Such a standpoint opens the door to the clarification of such fundamental issues and to possible new solutions to each of them.

From the mystical experiences of religious visions to the most degenerate forms of violence and pornography, the image, be it perceptual or conceptual, has imposed itself as a powerful form of human expression. The evocative, emotional and communicative power of images has been at the centre of a complex, often conflictual relationship in different societies, between exterior and internal forms of representation. Western history has passed alternately through periods of iconophilia and iconophobia, while various cultures have accorded different significance to (...) the capacity of vision to express and reinforce both the ideological and the political sphere. Referring to various examples, the article suggests that the pervasive presence of vision, far from being a self-evident, given element, is at the core of a problematic work of interpretation within the cultural contexts of societies. What appears to the eye can be considered the mirror of true reality or, alternatively, an ambiguous and superficial representation of it, in a dialectic confrontation between the iconic and the mental.

The relationship between the family of Benedetto Croce and that of Anton Dohrn were always characterized by cordiality and mutual respect. Both houses were international meeting places of artists, intellectuals and scientists. The narrowest and most lasting relationship was that between the philosopher and Reinhard Dohrn, from 1909 to 1965 director of the Zoological Station, a long period, marked, among other things, by the two World Wars. Both events caused major problems in the life of the institution. Starting in the (...) twenties, their relationship continued until 1952, the year of Croce’s death. In the years immediately following World War I Croce strove, with his prestige and authority, to preserve the Zoological Station’s nature as a private entity, directed by Dohrn. As Minister of Education, on 30 September, 1920, he issued a decree-law which repealed that of 26 May, 1918, which had aimed at the ‘Italianisation’ of the Zoological Station. Croce instead transformed the Station into a “non-profit organization under the supervision of the Ministry of Education”. The new decree sparked a lively debate in the Parliament and in the press, between supporters and opponents of the measure. On 9 December, a major discussion took place in the Senate, published in the same year under the title On the Zoological Station in Naples. The discussion revolved around two fundamental political concepts: is it legitimate to take, for reasons of culture, civilization and the law of war, possession of the “the fruit of the talent of others”? is it legitimate “to replace with a state organization” what had been created as a private activity and was the result of the enthusiasm and interest of individuals? Croce’s victory, however, was not lasting. During the Fascist era, with the decree of 21 October 1923, the Zoological Station was again transformed into an Italian state body. (shrink)

O objetivo deste texto é analisar o conceito de diversidade em Montesquieu e demonstrar como ele faz parte de seu tema da tolerância. Para atingir esse intento a noção de diversidade será abordada a partir de três campos de investigação específicos: o físico; o social; e o político, que, juntos, marcam o conceito de tolerância. Assim, espera-se contribuir para uma melhor compreensão desse conceito em Montesquieu.
