The Schwarzschild solution has played a fundamental conceptual role in general relativity, and beyond, for instance, regarding event horizons, spacetime singularities and aspects of quantum field theory in curved spacetimes. However, one still encounters the existence of misconceptions and a certain ambiguity inherent in the Schwarzschild solution in the literature. By taking into account the point of view of an observer in the interior of the event horizon, one verifies that new conceptual difficulties arise. In this work, besides providing a (...) very brief pedagogical review, we further analyze the interior Schwarzschild black hole solution. Firstly, by deducing the interior metric by considering time-dependent metric coefficients, the interior region is analyzed without the prejudices inherited from the exterior geometry. We also pay close attention to several respective cosmological interpretations, and briefly address some of the difficulties associated to spacetime singularities. Secondly, we deduce the conserved quantities of null and timelike geodesics, and discuss several particular cases in some detail. Thirdly, we examine the Eddington–Finkelstein and Kruskal coordinates directly from the interior solution. In concluding, it is important to emphasize that the interior structure of realistic black holes has not been satisfactorily determined, and is still open to considerable debate. (shrink)

We explore the intimate connection between spacetime geometry and electrodynamics. This link is already implicit in the constitutive relations between the field strengths and excitations, which are an essential part of the axiomatic structure of electromagnetism, clearly formulated via integration theory and differential forms. We review the foundations of classical electromagnetism based on charge and magnetic flux conservation, the Lorentz force and the constitutive relations. These relations introduce the conformal part of the metric and allow the study of electrodynamics for (...) specific spacetime geometries. At the foundational level, we discuss the possibility of generalizing the vacuum constitutive relations, by relaxing the fixed conditions of homogeneity and isotropy, and by assuming that the symmetry properties of the electro-vacuum follow the spacetime isometries. The implications of this extension are briefly discussed in the context of the intimate connection between electromagnetism and the geometry of spacetime. (shrink)

This study aims to investigate the relationship between job burnout and employee performance in the feed industry during the ASF outbreak. Further, the researchers employed a descriptive-correlational research design in order to analyze the acquired data and produce pertinent findings. Thus, the researchers gathered data from one hundred two (102) feed industry employees. The Maslach Burnout Inventory (MBI) and Individual Work Performance Questionnaire (IWPQ) were employed to ascertain the extent of job burnout experienced by the respondents and evaluate employee performance, (...) respectively. Based on the statistical analysis, there is a significant relationship between job burnout and employee performance. Moreover, the study's findings were thoroughly analyzed and discussed. (shrink)

If Unamuno had been able to choose how to be remembered, he would have wanted him to be a poet. This book wants to do justice to that happy possibility. But above all because Unamuno was a poet in the highest sense: he was while writing the same essay as a novel, or theater, letter or verse, and he was also a poet when he passionately lived all the facets of his intense existence. His intellectual work was poetic and his (...) personal relationships, as well as his political activity, also responded to that peculiar Unamunian aesthetic in which the vital horizon is inescapably confused with the tasks of thought." --Translated from back cover.

The coronavirus disease pandemic fundamentally disrupted humans’ social life and behavior. Public health measures may have inadvertently impacted how people care for each other. This study investigated prosocial behavior, its association well-being, and predictors of prosocial behavior during the first COVID-19 pandemic lockdown and sought to understand whether region-specific differences exist. Participants from eight regions clustering multiple countries around the world responded to a cross-sectional online-survey investigating the psychological consequences of the first upsurge of lockdowns in spring 2020. Prosocial behavior (...) was reported to occur frequently. Multiple regression analyses showed that prosocial behavior was associated with better well-being consistently across regions. With regard to predictors of prosocial behavior, high levels of perceived social support were most strongly associated with prosocial behavior, followed by high levels of perceived stress, positive affect and psychological flexibility. Sociodemographic and psychosocial predictors of prosocial behavior were similar across regions. (shrink)

: This response to Nikolaus Knoepffler's paper in the same issue of the Journal agrees that if the arguments supporting the first two of the eight human embryonic stem cell research policy options discussed are unsound, as Knoepffler argues, then it seems natural to move to the increasingly permissive options. If the arguments are sound, however, then the more permissive options should be rejected. It is argued that three of the rejected arguments, taken together, constitute very good reasons to hold (...) that a human embryo is endowed with dignity from fertilization onward. Thus, countries that want their public policies to match the moral imperative of respect for human beings should refrain from allowing destructive human embryo research and should devote considerable energy and public funds to research and clinical trials using non-embryonic ("adult") stem cells.

Why is space 3-dimensional? The fi rst answer to this question, entirely based on Physics, was given by Ehrenfest, in 1917, who showed that the stability requirement for n-dimensional two-body planetary system very strongly constrains space dimensionality, favouring 3-d. This kind of approach will be generically called "stability postulate" throughout this paper and was shown by Tangherlini, in 1963, to be still valid in the framework of general relativity as well as for quantum mechanical hydrogen atom, giving the same constraint (...) for space{dimensionality. In the present work, before criticizing this methodology, a brief discussion has been introduced, aimed at stressing and clarifying some general physical aspects of the problem of how to determine the number of space dimensions. Then, the epistemological consequences of Ehrenfest's methodology are critically reviewed. An alternative procedure to get at the proper number of dimensions, in which the stability postulate - and the implicit singularities in three-dimensional physics - are not an essential part of the argument, is proposed. In this way, the main epistemological problems contained in Ehrenfest's original idea are avoided. The alternative methodology proposed in this paper is realized by obtaining and discussing the n-dimensional quantum theory as expressed in Planck's law, de Broglie relation and the Heisenberg uncertainty relation. As a consequence, it is possible to propose an experiment, based on thermal neutron di raction by crystals, to directly measure space dimensionality. Finally the distinguished role of Maxwell's electromagnetic theory in the determination of space dimensionality is stressed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Form and Argument in Late Plato ed. by Christopher Gill and Mary Margaret McCabeFrancisco J. GonzalezChristopher Gill and Mary Margaret McCabe, editors. Form and Argument in Late Plato. Oxford: Oxford University Press, 1996. Pp. xi + 345. Cloth, $65.00.This collection has the commendable aim of challenging the view that in Plato’s “late” works the dialogue form is a mere formality adding little to the argumentative content, a view (...) still widespread among “analytic” scholars. The qualification is necessary because this view has already been seriously challenged by “nonanalytic” interpreters. It is therefore surprising that the editors chose contributors who almost all “share the analytic’ approach which is prominent in Anglo-American scholarship on Plato,” despite their admission that this approach has focused more on arguments than on the dialogue form (2, 299–300). Why seek to reinvent the wheel without the help of those who have already invented it? As a result, while the volume certainly makes an important contribution to our understanding of the form of this group of dialogues, it is much more successful in providing helpful and illuminating readings of their argumentative content: the detailed and rigorous analyses of McCabe, Malcolm Schofield (both on the Parmenides), and Gail Fine (on the Theaetetus) deserve special mention. The aim of the present review, which could not even begin to do justice to what the volume provides in the latter area, is therefore limited to documenting its mixed success in addressing some fundamental questions about form that have already occupied nonanalytic scholars (perhaps too exclusively):1) Does the main speaker speak for Plato?Given the great variety of main speakers in the “late” dialogues (Socrates, Parmenides, the Eleatic Stranger, Timaeus, the Athenian Stranger), each with a distinct personality and a distinct method, no attempt to understand the form of these dialogues should avoid this question. Gill raises it (293–95) and Schofield provides the most explicit response in denying that any interlocutor in a Platonic dialogue “can be assumed to be merely a spokesman for Plato’s own views” (51). More importantly, the essays by Dorothea Frede (on the Philebus) and Catherine Osborne (on the Timaeus), probably the most valuable in the volume, show what results can be achieved without this assumption. On the other hand, Michael Frede (on the Sophist) and Christopher Rowe (on the Politicus; see 158 and cf. 172 n.48) simply assume without argument that the Eleatic Stranger = Plato. All other contributors make the “spokesman” assumption, either implicitly or explicitly (see Christopher Bobonich’s reading of the Laws, 254–55).2) What is the significance of the dramatic context, especially dramatic chronology and characterization?As often noted, the Parmenides is set in Socrates’ youth and is in this sense the earliest [End Page 311] dialogue, while the series Theaetetus-Sophist-Politicus is set immediately before Socrates’ trial and condemnation. McCabe and Schofield are silent about the first fact. M. Frede briefly discusses the second (146–47), but adds little to what has already been said by others. As for the characterization of specific interlocutors, this volume overall has surprisingly little to offer. The essays of D. Frede and Osborne, however, are exemplary in this area.3) Why did Plato choose to write these works as dialogues rather than as treatises?Bobonich, D. Frede, and Osborne succeed in demonstrating the significance and even necessity of the dialogue form, an extraordinary achievement given the dialogues they discuss. Osborne in particular brilliantly shows how the dialogue form undercuts the common tendency to read the Timaeus as a treatise on natural science. Other contributors are less successful in answering this question central to the volume’s task. Schofield takes himself to be reading the Parmenides as a dialogue (51) because he, unlike Vlastos, interprets the Third Man Argument (second version) in the wider context of other arguments in the dialogue, including those of the second half. But “reading arguments in context” is demanded by any philosophical text and has nothing per se to do with the dialogue form. Fine reads the first part of the Theaetetus as the dialectical elaboration and refutation of an opponent’s view (109), but this could just as well be... (shrink)

Resumen En el presente artículo se explora la pertenencia de los libros M y N al programa general de la Metafísica de Aristóteles. Los libros XIII y XIV han quedado en el trasfondo de la Metafísica, como una suerte de agregado editorial, del cual se puede prescindir para la comprensión de la propuesta aristotélica. En el presente artículo, sin embargo, se asume un punto de partida diferente, que consiste en integrar estos libros al núcleo de la propuesta de la Metafísica, (...) enten diendo que ellos son claves para completar el panorama de la teoría general de la sustancia, o ousiología, que guía todos los libros metafísicos. De este modo, la discusión de M y N sobre números y principios viene a concluir la cuestión de la sustancia como causa y principio, anunciada desde el inicio de la Metafísica y desarrollada en sus libros centrales.This article explores the belonging of books M and N to the generalprogram of Aristotle's Metaphysics. Books XIII and XIV have remained in the background of Metaphysics, as a kind of editorial aggregate, which can be dispensed with for the understanding of the Aristotelian proposal. In this article, however, a different startingpoint is assumed, which consists in integrating these books into the core of the proposal of Metaphysics, understanding that they are key to completing the panorama of the general theory of substance, or ousiology, which guides all metaphysical books. Thus, the discussion of numbers and principles within M and N concludes the question of substance as cause and principle, announced from the beginning of Metaphysics and developed in its central books.

"The twelve chapters of this volume all began their existence as contributions to workshops held between 2009 and 2011 by a Danish-Swedish research network called The Aristotelian Tradition: The reception of Aristotle's works on logic and metaphysics in the Middle Ages, headquartered in Gothenburg and funded by the Bank of Sweden Tercentenary Foundation. Most of them were written by members of the network, some by invited speakers. While the volume amply illustrates the set of scholarly approaches characteristic of the "Copenhagen (...) School of Medieval Philosophy" (notably a strong philological foundation and an interest in ancient as well as medieval and Greek as well as Latin texts), its thematic diversity reflects the network's breadth of interests. What unites the chapters in this respect is simply a concern with different historical manifestations of Aristotelian thought on logical and metaphysical matters. The volume includes studies of texts by, among others, Apuleius, Boethius, Anonymus Aurelianensis III, Michael of Ephesus, Averroes, Anonymus Cantabrigiensis, Nicholas of Paris, Robert Kilwardby, Anonymus O, Thomas Aquinas, William of Ockham, and Francisco Suárez, relating to themes and passages in Aristotle's Categories, On Interpretation, Prior Analytics 1, Posterior Analytics 1, Sophistical Refutations and Metaphysics A and Z. The last two chapters consist of a new edition, with English translation and commentary, of the first part of a fiercely anti-Aristotelian work, which has been described as the starting-point for Renaissance Platonism and Aristotelianism alike: George Gemistos Plethon's On Aristotle's Departures from Plato."--.

What does environmental ethics have to say about the urban context? Is the city an environment that has only negative value or is it possible, and in fact necessary, to develop ethical recommendations about how to design it? In this paper, I argue for the second of these disjuncts and sketch some ideas for an environmental city ethics. I try to show that the most important principle of such an ethics is procedural: anyone affected by a decision about the urban (...) environment must have the possibility to participate in the process of making it. This principle has certain preconditions and there are also limitations on its applicability. For example, it is plausible that there are certain ecocentric ethical obligations, which are valid independently of the implementation of the principle. I sketch an idea for how a city’s green areas can help to raise citizens’ awareness of these obligations. -/- ¿Qué se puede decir, desde la ética ambiental, acerca del contexto urbano? ¿Se trata de un ambiente únicamente con valor negativo o es posible, e incluso necesario, desarrollar recomendaciones éticas sobre cómo diseñarlo? En este texto argumento en favor de la segunda afirmación y esbozo algunas ideas respecto de una ética ambiental para la ciudad. Defiendo que el principio más importante es procedimental: toda persona afectada debe tener la posibilidad de participar en la toma de las decisiones sobre el ambiente urbano. Este principio tiene ciertas precondiciones y también algunas restricciones. Por ejemplo, es plausible pensar en obligaciones éticas ecocéntricas válidas independientemente de la implementación del principio. Esbozo cómo las áreas verdes de una ciudad pueden ayudar a sensibilizar a los citadinos con estas obligaciones. (shrink)

This dissertation presents a new interpretation of Rene Descartes' views on body/body causation by examining them within their historical context. Although Descartes gives the impression that his views constitute a complete break with those of his predecessors, he draws on both Scholastic Aristotelian concepts of the efficient cause and existing anti-Aristotelian views. ;The combination of Aristotelian and anti-Aristotelian elements in Descartes' theory of causation creates a tension in his claims about the relationship between the first cause, God, and the secondary (...) causes, created things. To make sense of Descartes' position on secondary causation I study the 16th and 17th century debates on secondary causation, God's concurrence, and the action of efficient causes. I examine the Aristotelian commentaries of the Jesuit philosophers Francisco Suarez, Francisco Toledo, Antonio Rubio and the Coimbran Commentators. I also analyze the anti-Aristotelian views on nature and causation found in Sebastian Basson's textbook on natural philosophy. ;The Jesuit philosophers, like Descartes, deny that the extendedness and impenetrability of matter requires the existence of occult forces to penetrate the matter and exercise causality. Rather they argue that causality is exercised by a thing's form and that causal interaction requires only contiguity not penetration. They also downplay the importance of the final cause, making the efficient cause prior in the study of nature. While Descartes rejects their hylomorphism, he agrees with the Jesuits that there are secondary efficient causes which determine God's action, causing a specific kind of effect. However, for Descartes the secondary causes are the laws of nature, not individual substances. ;Descartes' reduction of all natural change to the local motion of material particles is reminiscent of Basson's anti-Aristotelian natural philosophy. Basson reacts against the Jesuit view of secondary causation, arguing that it commits them to attributing cognition to physical causes. His own account of natural causation contains both mechanistic elements, which we find in a more developed form in Descartes' philosophy, and Neoplatonic and Stoic elements which Descartes rejects.

In this paper, I explore the links between liberal political theory and the evaluative nature of medical classification, arguing for stronger recognition of those links in a liberal model of medical practice. All judgments of medical or psychiatric "dysfunction," I argue, are fundamentally evaluative, reflecting our collective willingness or reluctance to tolerate and/or accommodate the conditions in question. Illness, then, is "socially constructed." But the relativist worries that this loaded phrase evokes are unfounded; patients, doctors, and communities will agree in (...) the vast majority of cases about what counts as illness. Where they cannot come to agreement, however, we are faced with precisely the sort of dispute about values and ways of life that the institutions of the liberal state are designed to accommodate. I accordingly sketch a model of medical practice, based loosely on Jürgen Habermas's political theories, designed to maximize both our awareness and our understanding of these disputes. (shrink)

The civilizational turn in sociological theory is best understood as an attempt to do full justice to the autonomy of culture (against all versions of structural-functional theory) without conceding the issue to cultural determinism. Civilizational formations are based on combinations of cultural visions of the world with regulative frameworks of social life, but the relationship between the two levels is open to conflicting interpretations and strategic uses of them. Axial age civilizations open up new structural and historical dimensions of interaction (...) between cultural and social patterns, and are therefore central to the agenda of civilizational analysis. Among the later breakthroughs which draw on Axial sources, the emergence of modernity stands out as particularly important; the cultural and political program of modernity may be seen as a new and distinctive civilization, but it remains open to more or less formative influences from older civilizational legacies.

Individual semiotic systems interpreting their environment are not well understood from the externalist approach typical of the scientific method. Science constructs probabilities describing large populations of systems, not individuals. The Umwelt, as the individually experienced/created aspects of the habitat aspect of its population’s ecological niche, is given an internalist understanding within the framework of the compositional hierarchy. Vagueness is an important aspect of the internalist condition. It is selectively reduced momentarily by creative choices that can have a Peircean semiotic formulation, (...) and which are often unpredictable externally, thereby appearing to be chance events.

I propose to examine here, at the outset, what I call the asymmetry in Thomas Hobbes's thought between his treatment of civil war and war between states, that is to say, between the departure from the state of nature - when that is a condition prevailing between individuals - and the permanency in the state of nature when it forms a condition existing between states. Secondly, I will address the Kantian progression beyond this asymmetry through the dual introduction of the (...) idea of progress and of ‘cosmo-political’ peace. The attention given in recent years by Habermas to the Kantian idea of perpetual peace [Habermas, 1996], the recent events in Kosovo and Chechnya, and their implications for the shape of an international penal tribunal to judge crimes against humanity, invigorate the questions of civil peace and of rights which transcend state frontiers.

Biography of Jiddu Krishnamurti, 1895-1986, Indian philosopher.

This paper is based on four assumptions concerning the analysis of the construction of collective identities. First, such construction, like power and economic relations, is an analytically autonomous basic component of the construction of social life. Second, such constructions have been going on in all human societies throughout history. Third, all such patterns of collective identity have been continually constructed from some basic yet continually changing building blocks, codes or themes - especially those of primordiality, civility and `sacredness'. The paper (...) focuses on the different patterns of modern nation states in the framework of the more general approach to the construction of collective identities. This analysis of different modern nation states indicates that despite common characteristics, there developed great differences in their construction; in the analysis of such differences it is very important to take into account the historical and civilizational backgrounds of the respective societies.

Treatise with auto-commentary on Dvaita philosophy.

It is the major argument of this essay that the roots of modern Jacobinism in their different manifestations are to be found in the transformation of the visions with strong Gnostic components and which sought to bring the Kingdom of God to earth and which were often promulgated in medieval and early modern European Christianity by different heterodox sects. The transformation of these visions as it took place above all in the Great Revolutions, in the English Civil War and especially (...) the American and French Revolutions and their aftermaths, entailed their transposition from relatively marginal sectors of society to the central political arena. From then on, these visions, especially in their various collectivistic, especially Jacobin, guises became a continual component of the modern political discourse and dynamics, in continual confrontation with more 'open' pluralistic visions.

Japan constitutes a very interesting and paradoxical case from the point of view of the place of trust in the processes of institution building and institutional dynamics. This problem has, of course, been the basic thrust of Durkheim's emphasis on the importance of precontractual elements for the fulfillment of contracts seemingly dealing with purely considerations. But this crucial insight has not been systematically followed up in the social science literature. Only lately it has been again taken up from within various (...) rational choice approaches which have come to recognize that continuity of patterns of social interaction and of institutional frameworks cannot be explained by purely rational-utilitarian considerations (Braithwaite and Levi, 1998; Kramer and Tyler, 1993). At the same time the more recent analyses have also pointed to some of the complexities, paradoxes; and problems of the construction of trust in social interaction and institution building. (shrink)
