In this paper the scientific trajectory of Spanish influential biochemist Alberto Sols (1917–1989) is presented in comparative perspective. His social and academic environment, his research training under the Cori's in the US in the early 1950s and his works when coming back to Spain to develop his own scientific career are described in order to present the central argument of this paper on his path from physiological research to research on enzymatic regulation. Sols' main contributions were both scientific and academic. (...) He and his collaborators not only contributed to biological knowledge on the biochemistry of metabolic regulation but to the active reception of biochemistry in the Spanish academia and to update of Spanish medical education. -/- .

Clinical trials of xenotransplantation may begin early in the next decade, with kidneys from genetically modified pigs transplanted into adult humans. If successful, transplanting pig hearts into children with advanced heart failure may be the next step. Typically, clinical trials have a specified end date, and participants are aware of the amount of time they will be in the study. This is not so with XTx. The current ethical consensus is that XTx recipients must consent to lifelong monitoring. While this (...) presents challenges to the right to withdraw in the adult population, additional and unanswered questions also linger in the paediatric population. In paediatric XTx, parents or guardians consent not only to the initial treatment of the child but also to lifelong monitoring, thus making a decision whose consequences will remain present as the child develops the capacity for assent, and finally the capacity for informed consent or refusal. This article presents and evaluates unanswered paediatric ethical questions in regard to the right to withdraw from XTx follow-up in the paediatric population. (shrink)

La posibilidad de sentar las bases para una psicología platónica de la acción puede ser abordada desde la perspectiva de la conexión entre la doctrina del alma tripartita de República y la psicología del placer del Filebo. A la luz de dicha conexión, la noción del alma como fuente del deseo se constituye en factor determinante de nuestro carácter personal y nuestra forma de actuar, lo que hace posible construir una tipología de hombre basada en la primacía de una parte (...) de su alma y en su preferencia por cierta clase de placer. Palabras clave: Platón; Psicología; Placer; Alma; Deseo; AcciónThe possibility of laying the foundations of a Platonic psychology of action can be tackled from the connection between Republic’s tripartite soul doctrine and Philebus’ psychology of pleasure. In the light of this connection, the notion of soul as the source of desire is a determining factor of our personal character and the way we act. This makes it possible to construct a typology of man based upon the primacy of one part of his soul and his preference for a certain kind of pleasure. Keywords: Plato; Psychology; Pleasure; Soul; Desire; Action. (shrink)

Resumen Cuando el 6 de agosto de 1945 los científicos del proyecto atómico alemán dirigido por el físico Werner Heisenberg escucharon desde su encierro en Farm Hall la noticia de que Estados Unidos había arrojado una bomba nuclear que había destruido Hiroshima, comenzó la construcción de la historia: la versión que Heisenberg ofreció en su autobiografía intelectual fue que sabía que el proyecto era inviable a corto y medio plazo y, por tanto, no había riesgo en asumir la investigación. Siguiendo (...) las tesis de filosofía de la historia de Benjamin, pasaré el cepillo a contrapelo a esta construcción de la historia de la ciencia para sacar a la luz varias razones que la desmontan. Para ello recurriré a la filosofía de la ciencia de Popper, Kuhn y Lakatos y a la critica de Marcuse a la racionalidad tecnológica. La finalidad es triple: cuestionar la visión de la ciencia sostenida por Heisenberg, mostrar la influencia que ejercen los grandes proyectos científico - tecnológicos sobre el modo de pensar y actuar de los individuos y salvar los dos abismos denunciados por el físico y novelista C. P. Snow, uno entre ciencias y humanidades y otro entre quienes poseen conocimiento especializado y quienes no.When, on August 6, 1945, the scientists ofthe German atomic project led by physicist Werner Heisenberg heard the news from their confinement in Farm Hall, England, that the United States had dropped a nuclear bomb that destroyed Hiroshima, the construction of history began: Heisenberg's version in his intellectual autobiography was that he knew the project was unviable in the short and medium term and, therefore, there was no risk in advancing the research. Following Benjamin's theses on the philosophy of history, I will brush against this construction of the history of science to bring to light several reasons that dismantle this construction. To do this I will resort to the philosophy of science of Popper, Kuhn and Lakatos and Marcuse's criticism of technological rationality. The aim is threefold: to question the vision of science held by Heisenberg, to show the influence of the great scientific-technological projects on the way of thinking and acting of individuals and to bridge the two abysses denounced by the physicist and novelist C. P. Snow, one between sciences and humanities and the other between those who have specialized knowledge and those who do not. (shrink)

This solves the open problem of Fokina, Kalimullin, and Miller [13].For a computable structure${\cal S}$, we introduce the notion of the spectral dimension of${\cal S}$, which gives a quantitative characteristic of the degree of categoricity of${\cal S}$. We prove that for a nonzero natural numberN, there is a computable rigid structure${\cal M}$such that$0\prime$is the degree of categoricity of${\cal M}$, and the spectral dimension of${\cal M}$is equal toN.

The problem of life’s origin remains one of the great outstanding challenges to science. Ever since Charles Darwin mused about a “warm little pond” incubating life beneath sunny primeval skies, scientists have speculated about the exact location of this transforming event. Nearly a century and a half later, we remain almost completely ignorant of the physical processes that led from a nonliving chemical mixture to the first autonomous organism. However, some progress at least has been made on tracking down where (...) and when life first established itself on Earth. Fossil evidence suggests that the biological record extends back at least 3.5 billion years, pointing to a still earlier origin1. But this presents a problem. The cratering record of the moon implies that Earth was subjected to intense bombardment by large comets and asteroids over an extended duration until about 3.8 billion years ago. The largest of these impacts would have released enough energy to swathe the planet in incandescent rock vapour, boiling the oceans and sending sterilizing heat pulses a kilometre into the exposed crust2. This unpromising setting – hardly a secure one for warm little ponds – has prompted some astrobiologists to conjecture that life began somewhere else and came to Earth readymade3. Favourite among extraterrestrial originating locations is the planet Mars4. (shrink)

Nagel, San Juan, and Mar report an experiment investigating lay attributions of knowledge, belief, and justification. They suggest that, in keeping with the expectations of philosophers, but contra recent empirical findings [Starmans, C. & Friedman, O. (2012). The folk conception of knowledge. Cognition, 124, 272–283], laypeople consistently deny knowledge in Gettier cases, regardless of whether the beliefs are based on ‘apparent’ or ‘authentic’ evidence. In this reply, we point out that Nagel et al. employed a questioning method that biased participants (...) to deny knowledge. Moreover, careful examination of participants’ responses reveals that they attributed knowledge in Gettier cases. We also note that Nagel et al. misconstrue the distinction between ‘apparent’ and ‘authentic’ evidence, and use scenarios that do not feature the structure that characterizes most Gettier cases. We conclude that NS&M’s findings are fully compatible with the claim that laypeople attribute knowledge in Gettier cases in general, but are significantly less likely to attribute knowledge when a belief is generated based on apparent evidence.

Resumen: El presente artículo quiere ofrecer un análisis de la evolución de la pintura chilena del siglo XIX, indagada a partir de la interpretación del tema hídrico en la producción pictórica de tres de los artistas más representativos en los ámbitos de la pintura de paisaje, del marinismo y de la pintura de glorias navales. En particular nos referiremos a las creaciones de Antonio Smith, Charles Wood y Thomas Somerscales, cuyas representaciones de ríos, lagos y sobre todo del Océano Pacífico (...) son una prueba de la fecunda etapa decimonónica que esta disciplina vivía en Chile. Nos fijaremos en el estudio de las tres claves de composición, luz y color en un conjunto de obras guardadas en prestigiosas colecciones públicas y privadas, seleccionadas atendiendo a los juicios sobre las relevantes cualidades técnicas y estéticas reconocidas en ellas por la crítica y la historiografía artísticas actuales.: The present article has the purpose to offer an analysis of the evolution of chilean painting during the 19th century, investigated from the interpretation of the water in the pictorial production of three of the most representative artists in the field of landscape, sea and naval glory painting. In particular, we will refere to the creations of Antonio Smith, Charles Wood and Thomas Somerscales, whose representations of rivers, lakes and especially Pacific Ocean are a proof of the productive phase that in 19th century painting had in Chile. We will focus on the study of the three keys of composition, light and color in a combination of works kept in precious public and private collections, selected due to the judgment about the relevant technical and esthetic qualities by the actual artistic critics and historiography.

With the end of the Cold War, political and ideological competition has decreased as a stated reason for space exploration. The possibility of establishing a settlement on Mars is being seriously evaluated by state and commercial space agencies, which includes objectives to expand human civilization and ensure the continuity of the human species. The technological challenges associated with space settlement continue to receive significant attention, but the success of space settlement will also depend on other human factors. This study presents (...) a high-level overview of some potential issues that could arise with the development of a permanent populationand a space economyon Mars. This study highlights some of the anticipated problems of overnance, trade, production, and proliferation that will need pragmatic solutions to ensure the sustainability of a martian settlement. This paper is intended to instigate further discussion and research regarding human and economic factors that could enable or constrain future settlements on Mars. (shrink)

Given a d.c.e. degree d, consider the d.c.e. sets in d and the corresponding degrees of their Lachlan sets. Ishmukhametov provided a systematic investigation of such degrees, and proved that for a given d.c.e. degree d > 0, the class of its c.e. predecessors in which d is c.e., denoted as R[d], can consist of either just one element, or an interval of c.e. degrees. After this, Ishmukhametov asked whether there exists a d.c.e. degree d for which the class R[d] (...) has no minimal element. We give a positive answer to this question. (shrink)

Levando–se em conta os leitores do século XXI, ao debruçar-se sobre a participação da Igreja católica brasileira na preparação do Concílio Vaticano II, o presente estudo parte de três perguntas: a) o quê interessa saber sobre a participação brasileira? b) É este um tema relevante? c) Alguns brasileiros participação significativamente na fase preparatória? Para responder apropriadamente a essas questões os autores propõem um conceito diferente de “participação” na preparação do Vaticano II por parte do episcopado brasileiro. O artigo não foca (...) apenas a presença deste ou daquele bispo ou perito nas comissões do Concílio, mas propõe a idéia de que o mais importante foi a auto-preparação, que durante certo tempo permaneceu “latente” e posteriormente se organizou através de um Concílio com um episcopado jovem, com uma média de idade em torno de 54 anos e 11 de experiência como bispo. Por isso, conscientes dos problemas pastorais que a realidade do subdesenvolvimento punha à Igreja, e com uma incipiente experiência de participação colegial, desenvolvida na construção do Plano de Emergência, este episcopado não só vivenciou em profundidade o “evento” conciliar, como foi o primeiro a sair dele organizado para colocá-lo em prática. Daqui a relevância desta reconstrução. Palavras-chave: Helder Câmara. Plano de Emergência. Colegialidade. Vaticano II. Igreja Católica no BrasilThis article aims to show the contribution of the Brazilian Catholic Church in the preparation of the Second Vatican Council. To fulfill such purpose the present study focus its research in three basic questions: a) what is important to know about the Brazilian participation? b) Is this a relevant topic? C) Some Brazilians participate significantly in the preparatory phase? To respond appropriately to these issues the authors propose a different concept of "participation" in the preparation of Vatican II by the Brazilian episcopate. The article focuses not only the presence of this or that bishop or the expert commissions of the Council, but proposes the idea that the most important was the self-preparation, which for a time remained "latent" and later was organized by a council with a young bishop, with an average age around 11 and 54 years of experience as a bishop. Therefore, aware of the problems that the pastoral reality of underdevelopment put the Church, and with an incipient experience of participating high school, developed in the construction of the Emergency Plan, the bishops not only experienced in depth the "event" to reconcile, as was the first it held out to put it into practice.

O artigo pretende sublinhar a incompatibilidade que a hermenêutica filosófica de Gadamer apresenta com relação ao projeto filosófico de Heidegger. O objetivo é, desta forma, problematizar a ideia segundo a qual a hermenêutica filosófica constitui um desdobramento representativo do pensamento heideggeriano. A hermenêutica de Gadamer é percebida aqui como estando comprometida com uma tarefa de refundação, e a práxis, entendida como imanência da vida histórica, se mostra precisamente como um novo fundamento. O encontro de Gadamer com a práxis revela-se, assim, (...) à luz de uma não identificação, ainda que pouco explícita, da hermenêutica filosófica em relação ao projeto heideggeriano. (shrink)

Insight into Lester Embree’s C.V. Recovery and recognition of his inner purpose with regard to his critical detachment from a particular orientation of phenomenology. Phenomenological theory only makes sense as prepa-ration for real practice. When did the view that we, the “soi disant” phenomenologists, are far from the genuine practice of phenomenology arise in Embree? And, who inspired him, apart from Husserl himself? These are key questions to understand unity and inner coherence in Embre’s C.V., and they meet two aims. (...) The first one is to find the link between his initial entry in phenomenology and his critical stance, particularly evident in the last two decades of his life. The second one is to identify who could have been his guide and model‒apart from Husserl‒from the beginning of his life as phenomenologist until his last two decades, when he wrote his comments on pseudophenomenology. In any case, Embree has been a critical voice who compels us to think about the orientation we are giving to the phenomenology inherited from Husserl. He is therefore a brave and honest philosopher, full of great humanity. In addititon to these qualities, it is worth noting both his creative intelligence and foresight to see‒earlier than others‒the evolution followed by phenomenology until now and his valuable multidisciplinary contribution. Praise to Lester Embree.Mirada hacia el interior del C.V. de Lester Embree. Recuperación y reconocimiento de su propósito interno con respecto a su distanciamiento crítico hacia cierta orientación de la fenomenología. La teoría fenomenológica únicamente tiene sentido como preparación para una real práctica. ¿Cuándo emerge en Embree su consideración de que los “soi disant” fenomenólogos estamos alejados del verdadero ejercicio de la fenomenología? Y, ¿en quién se inspira él además de en Husserl? Estas preguntas son importantes para entender la unidad y coherencia internas en el C.V. de Embree y sirven para satisfacer dos objetivos. El primero es hallar un vínculo entre su entrada inicial en la fenomenología y su posicionamiento crítico manifiesto especialmente en las últimas dos décadas de su vida. El segundo objetivo es determinar quién pudo actuar para él —además de Husserl— como guía y modelo desde el comienzo de su vida de fenomenólogo hasta esas dos últimas de su vida en las que escribe sus comentarios sobre la pseudofenomenología. En todo caso, Embree es una voz crítica que nos fuerza a pensar acerca de la trayectoria que nosotros estamos dando a la fenomenología heredada de Husserl. Él es, así, un filósofo valiente y honesto y de una gran humanidad. Se unen a estas cualidades su gran inteligencia creativa y su sorprendente perspicacia para ver —antes que otros— la evolución que ha seguido la fenomenología hasta hoy y la valiosa contribución multidisciplinar actual. Alabanza a Lester Embree. (shrink)

Nosso estudo não consistirá unicamente no exame do pensamento religioso de Bergson. E também não será uma reflexão específica sobre sua filosofia da natureza ou ainda sobre sua filosofia da ciência. Nosso objetivo se situa na junção das ideias bergsonianas sobre o natural e o sobrenatural, sobre o filosófico e o religioso, sobre a ciência e a metafísica. Mas tal empreitada corre um grande risco: o de justapor, em um primeiro momento, estes diferentes campos de reflexão para, em um segundo (...) momento, tentar reuni-los. O élan vital nos parece o caminho mais seguro para nos proteger deste risco. Uma vez que ele está na intersecção de diferentes ordens do pensamento de Bergson, ele não favorece apenas sua articulação, ele o demanda. Consequentemente, é do ponto de vista interno à filosofia da natureza que aparece a questão religiosa em Bergson. Tal é a hipótese que formulamos.Resumé: Notre étude ne consistera pas uniquement en l’examen de la pensée religieuse chez Bergson. Elle ne será pas non plus une réflexion spécifique sur sa philosophie de la nature ou encore sur sa philosophie des sciences.

Mais une telle enterprise court un risque majeur, celui de juxtaposer, dans un premier temps, ces différentes champs réflexifs pour, dans un deuxième moment, tenter de les reunir. L’élan vital nous apparaît le moyen le plus certain de prevenir ce risque. Parce qu’il est à l’intersection des différents ordres de la pensée de Bergson, il ne favorise pas seulement leur articulation, il l’exige. Par conséquent, c’est d’um point de vue interne à la philosophie de la nature elle-même que se pose la question religieuse chez Bergson. Telle est l’hypothèse que nous formulons.

Célestin Freinet a été arrêté le 20 mars 1940 comme militant communiste, sur ordre du Préfet des Alpes-Maritimes, et interné dans divers camps du sud de la France jusqu'au mois d'octobre 1941. C'est à " former en l'enfant l'homme de demain ", un enfant plus instruit, plus responsable, plus heureux, que s'est attaché cet infatigable promoteur d'une pédagogie nouvelle coopérative. On retrouvera dans ces lettres l'essentiel de la réflexion éducative contenant en germe ses deux ouvrages majeurs, " l'éducation du travail (...) " et " Essai de psychologie sensible ", écrits lorsque Freinet est assigné à résidence en 1941. Mais le témoignage de cet esprit pénétrant et engagé est également remarquable pour sa valeur historique : son regard éclaire sous un jour encore assez peu connu, la misère morale et matérielle des internés, leurs souffrances et leur détresse, leur puissance à résister aussi. Ce volume épistolaire intéressera à la fois tous les curieux de l'œuvre de Freinet, tous ceux que l'éducation nouvelle et la rénovation de l'enseignement préoccupent, et ceux que ne laisse pas indifférents cette période dramatique de notre Histoire racontée au jour le jour, et à laquelle Elise Freinet apporte un écho attentif et émouvant.

In the New Testament, the resurrection of Jesus is not described as a visible event, and for this reason, the resurrection was not represented directly in visual arts for about 1,000 years. Direct representations of the resurrection as an event appeared only after 1000 C.E. They were concrete, and they objectivized and historicized the resurrection in a problematical way.

Resumen El presente artículo plantea la necesidad de un acercamiento histórico a los textos filosóficos tomando como ejemplo el caso de la propuesta ética de David Hume. Se muestra el interés de Hume por insertarse en el diálogo intelectual de su época y su propósito de integrar el método científico en las ciencias morales y cómo la crítica que hace a la razón debe ser comprendida bajo esta luz. Para ello se menciona el ambiente intelectual de la época y las (...) posturas en conflicto en el debate filosófico del siglo XVIII: el escepticismo-relativista, el racionalismo exagerado y el sentimentalismo ingenuo, señalando que, en el fondo, Hume no puede ser excluido totalmente de ninguna de estas posturas pero tampoco encasillado en alguna de ellas.This article raises the need of a historical approach to philosophical texts taking as an example the case of David Hume’s ethics proposal. It shows Hume`s interest in participating actively in the intellectual dialogue of his time and his intention to integrate the scientific method into the moral sciences and how his critique of reason must be understood in this light. To do this, we quickly mention the intellectual atmosphere of the time and the positions in conflict in the philosophical debate of the 18th Century: relativistic skepticism, radical rationalism and naive sentimentality, noting that, deep down, Hume cannot be excluded completely from any of these positions but not typecast in any of them.

The hypothesis that life’s rapid appearance on Earth justifies the belief that life is widespread in the universe has been investigated mathematically by Lineweaver and Davis (Astrobiol- ogy 2002;2:293–304). However, a rapid appearance could also be interpreted as evidence for a nonterrestrial origin. I attempt to quantify the relative probabilities for a non-indigenous ver- sus indigenous origin, on the assumption that biogenesis involves one or more highly im- probable steps, using a generalization of Carter’s well-known observer-selection argument. The analysis is (...) specifically applied to a Martian origin of life, with subsequent transfer to Earth within impact ejecta. My main result is that the relatively greater probability of a Mar- tian origin rises sharply as a function of the number of difficult steps involved in biogene- sis. The actual numerical factor depends on what is assumed about conditions on early Mars, but for a wide range of assumptions a Martian origin of life is decisively favored. By con- trast, an extrasolar origin seems unlikely using the same analysis. These results complement those of Lineweaver and Davis.

Pomeau has condensed a lot of material for this pocket-size introduction to the life and works of Diderot, which he has attempted to simplify by providing parallel classifications of the excerpts from Diderot's works with his own presentation of Diderot's philosophy. These divisions are entitled: the Adventure of Diderot's thought, On Nature, On Man, Morality, Aesthetics, Politics, and the Contemporary Import of Diderot's Philosophie. Pomeau, a Voltaire scholar, displays a knowledge of the intellectual history of the period and a wide (...) acquaintance with his immediate material. His selections are beautifully chosen, for they provide a generous survey of Diderot's work, including even a short passage from the most recently published marginalia of Hemsterhuis. This sort of presentation cannot but entice the beginner to further examination, for the passages range from the most poignant to the most witty Yet there is matter to frustrate the serious beginner; the passages are not dated, nor are they identified by work in the index. Pomeau engages in gratuitous psychologizing in his exposition of Diderot's life, and has made a blatant error in attributing to Diderot the authorship of the article "Encyclopédie." These shortcomings unfortunately mar a text which contains excellent analyses of the evolution of Diderot's religious and biological thought.—C. M. R. (shrink)

For over half a century, scholars have laboured to show that C. S. Lewis's famed but apparently disorganised Chronicles of Narnia have an underlying symbolic coherence, pointing to such possible unifying themes as the seven sacraments, the seven deadly sins, and the seven books of Spenser's Faerie Queene. None of these explanations has won general acceptance and the structure of Narnia's symbolism has remained a mystery. -/- Michael Ward has finally solved the enigma. In Planet Narnia he demonstrates that medieval (...) cosmology, a subject which fascinated Lewis throughout his life, provides the imaginative key to the seven novels. Drawing on the whole range of Lewis's writings (including previously unpublished drafts of the Chronicles), Ward reveals how the Narnia stories were designed to express the characteristics of the seven medieval planets - - Jupiter, Mars, Sol, Luna, Mercury, Venus, and Saturn - - planets which Lewis described as "spiritual symbols of permanent value" and "especially worthwhile in our own generation". Using these seven symbols, Lewis secretly constructed the Chronicles so that in each book the plot-line, the ornamental details, and, most important, the portrayal of the Christ-figure of Aslan, all serve to communicate the governing planetary personality. The cosmological theme of each Chronicle is what Lewis called 'the kappa element in romance', the atmospheric essence of a story, everywhere present but nowhere explicit. The reader inhabits this atmosphere and thus imaginatively gains connaître knowledge of the spiritual character which the tale was created to embody. -/- Planet Narnia is a ground-breaking study that will provoke a major revaluation not only of the Chronicles, but of Lewis's whole literary and theological outlook. Ward uncovers a much subtler writer and thinker than has previously been recognized, whose central interests were hiddenness, immanence, and knowledge by acquaintance. (shrink)

Computably enumerable equivalence relations received a lot of attention in the literature. The standard tool to classify ceers is provided by the computable reducibility \. This gives rise to a rich degree structure. In this paper, we lift the study of c-degrees to the \ case. In doing so, we rely on the Ershov hierarchy. For any notation a for a non-zero computable ordinal, we prove several algebraic properties of the degree structure induced by \ on the \ equivalence relations. (...) A special focus of our work is on the existence of infima and suprema of c-degrees. (shrink)

The author considers the conditions which render possible communication and signifying. Acknowledging that most of the literature now published deals with Anglo-Saxon and Germanic studies, he hopes to effect an application to the Italian language and way of thinking. His arguments are difficult to appreciate because they begin from too broad a base of assumptions. Although having emphasized a desire to strengthen the case for "common sense," he seems brutally to neglect that ideal. Rossi-Landi assumes that all language is construction (...) and accepts as an immediate corollary that thought is another construction. From this basis he pursues faithfully a value-free, historicist-oriented explanation of language which is marred by reasoning that abounds in non-sequitur. No one will deny the interest of the original problem, nor its relevance to the question of philosophy; it is to be regretted that more careful arguments have not been offered.--C. E. B. (shrink)

Walsh admirably achieves the objective of this book, which is to supply the need for a lucid commentary on Kant’s first Critique that is both faithful to making the text clear and a sophisticated assessment of the arguments. Walsh’s work exemplifies patience, scholarship, and philosophical acumen. In response to the conventional criticism that Kant’s theses are marred by a psychological idiom, Walsh translates Kant into the contemporary linguistic idiom in a way that preserves the original remarkably well.

An historical and critical survey of the various theories of totemism. Lévi-Strauss believes almost every theory explaining the relation held to exist between man and certain natural objects can be demolished: there seems to be no general biological or cultural framework which can account for totemism as an isolated phenomenon. But if totemism is seen as a way of thinking metaphorically, of correlating opposites, or of associating by contrariety then it becomes an example of a mode of thinking common to (...) sophisticated as well as primitive peoples. Observations by Bergson and Rousseau, made outside the framework of modern anthropology, bear out Lévi-Strauss' thesis. A fascinating work, marred only by a rather stiff translation.—C. L. B.

L'itinéraire singulier d'une femme que l'on pourrait, par bien des aspects, considérer comme appartenant à un passé déjà lointain, suscite pourtant chez nombre de nos contemporains un intérêt de plus en plus grand. Edith Stein - connue également sous le nom, qu'elle prit au Carmel, de Thérèse-Bénédicte de la Croix - reste aux yeux de beaucoup un témoin particulièrement saisissant des drames fondamentaux qui ont jalonné le XXe siècle européen et dont nous sommes, pour le meilleur comme peut-être pour le (...) pire, les héritiers. C'est à ce titre que sa vie et son message peuvent constituer pour notre avenir une lumière digne d'être interrogée. S'il est vrai que l'Europe doit d'abord et avant tout être un espace où vivent et se rencontrent des êtres humains capables de promouvoir une culture empreinte de dignité et de responsabilité, il était alors tout naturel de prendre comme fil conducteur de ce colloque le thème essentiel de la réflexion steinienne : la question de la personne humaine. Quatre approches complémentaires ont été choisies pour déployer quelques-unes des composantes de cette interrogation : L'enracinement philosophique d'Edith Stein dans le milieu phénoménologique de Göttingen, sa situation dans l'histoire de son temps, son activité d'éducatrice au service de la formation intégrale de la personne humaine, l'accomplissement de son engagement intellectuel dans la réflexion théologique et l'expérience du mystère de la Croix.

Respect for human life is central to medicine. In terminal patients, refractory symptoms are a niche of palliative sedation. This paper identi es, based on scienti c evidence, the survival in patients who received palliative sedation as compared to those who didn’t. We conducted a search for systematic reviews from 2000 to 2016, which were methodologically analyzed, and the results were then compared. For methodological reasons, meta-analysis could not be performed. It is concluded that terminal palliative sedation does not shorten (...) patients’ lives. The implementation of the principle of double effect related to the possible shortening of life was reformulated; the unwanted evil is the loss of consciousness. (shrink)

A general consensus has emerged among twentieth-century commentators on the Aeneid that pater ipse…superum must be taken together and understood as referring to the father of the gods and not to Mars, sire of Romulus. What remains a subject of debate is the meaning of honor here and its particular association with Jupiter. Does it betoken the abstraction itself or a concrete manifestation of it? Austin, following Donatus, opts for the former alternative , Norden and R. D. Williams for the (...) latter. Of these the first finds a reference to the Zeus-given sceptre of kings, the second to Jove's thunderbolt. The language of the passage argues in favour of metonymy for two reasons. First, we expect Anchises, when showing off Romulus, to adhere to the pattern he has already set in the two portions of his parade which have preceded. In the case of the initial hero, Silvius, we attend largely to genealogical background . The second segment, a group made up of Procas, Capys, Numitor and Aeneas Silvius, elicits from Aeneas' father a series of exclamations on the valour of their res gestae . Yet each also has a tangible symbol of martial virtus that distinguishes him. (shrink)

A literatura chamada de “apocalíptica” tem recebido uma renovada apreciação nos últimos anos. Entretanto, percebe-se certa confusão terminológica que, por fim, leva a uma classificação equivocada do gênero de certos escritos. O presente artigo tem por finalidade analisar as conceituações e as expressões literárias da apocalíptica, com o intuito de se chegar a uma definição mais clara do tema, distinguindo apocalipse enquanto gênero literário e apocalíptica enquanto mentalidade , com as formas básicas de expressão literária do gênero e seus paralelos (...) antigos. Assim sendo, o artigo é dividido em duas partes: primeiramente, verificam-se as definições e características atribuídas ao gênero apocalíptico pelos principais autores do tema, especialmente no que se refere aos escritos judaico-cristãos produzidos entre 250 a.C. e 100 d.C.; em seguida, verificam-se os paralelos antigos presentes na literatura de outros povos, como os sumérios, os persas e os gregos. Por fim, faz-se uma breve análise da ocorrência dessa literatura nos Manuscritos do Mar Morto. Isto posto, chega-se à conclusão de que é possível fazer a distinção acima proposta, a qual traz maior clareza na definição e classificação dos escritos ao gênero atribuídos. (shrink)

O presente artigo é uma discussão sobre a noção heideggeriana de Überwindung. Seu objetivo é duplo: por um lado, [1] mostrar a perspectiva que tal termo deve ser compreendido; por outro, [2] aprofundar esta perspectiva à luz de comentários ao aforismo I do texto Überwindung der Metaphysik. Para tanto, duas questões são postas: em que perspectiva e que questões estão implícitas quando Heidegger propõe o projeto da Überwindung der Metaphysik?; e por que uma Überwindung contém em si tantos problemas? De (...) modo a discutir e comentar tais questões, o artigo percorre dois caminhos: [1] faz-se uma análise da própria indicação heideggeriana da perspectiva de compreensão da Überwindung der Metaphysik, qual seja, revisitar, a partir de um olhar determinado, a construção da noção de história do ser. Esta, por sua vez, tem sua gênese antes mesmo da própria Kehre. Mais especificadamente, na reinterpretação que o próprio Heidegger faz de seu texto Vom Wesen der Wahrheit. A partir desta reconsideração feita por Heidegger e inserida em seu próprio texto, é possível detectar quatro teses fulcrais que traçam essencialmente a metafísica e que justificam a sua superação. São elas: [a] o fato de o ser, originariamente, se velar e provocar, historialmente, o seu esquecimento; [b] a relação entre a verdade do ser e a história, que se desenvolve como história do ser; [c] a ideia de que pertence ao ser um caráter originário de retração de si mesmo e que essa retração é um destino que pertence à história do pensamento metafísico e se configura na própria essência da metafísica; [d] afirmar que a certeza da manifestação da essência coincide com o seu fim. [2] Adentra-se, mediante uma aproximação pari passu, no aforismo I do texto Überwindung der Metaphysik, com intuito de comentar a problematicidade do termo Überwindung quando usado para repensar a metafísica à luz da perspectiva da história do ser.

Gaston Bachelard's thought remains a continual source of inspiration for a phenomenological psychology that takes human habitation as a fundamental given and as an abiding mystery of the human condition. the following essay explores the ideas Bachelard developed in the course of his study of poetry. It examines in particular his vision of imagination as a unique passage way by means of which we reach an inhabitable, intersubjective and fully human world. Within that perspective, our lives are constantly renewed by (...) the appearance of a revealing image or a telling metaphor. Each time that we are awakened by this appeal we commemorate the birth and rebirth of a human world. (shrink)

These two small works are a good supplement to Rescher’s recent trilogy. Whereas the systems-theoretic approach is employed in Methodological Pragmatism in dealing with the problem of the legitimation of claims to factual knowledge or cognitive rationality, Dialectics deals with the argumentation aspect of thesis-introduction rather than the logical aspect of thesis-derivation. Although some key notions such as the idea of burden of proof and presumption have been stated in the former work, what is offered here is a systematic discussion (...) of a disputational model of inquiry. The principal aims are "to exhibit the sociocommunal roots of the foundations of rationality, to provide an instrument for the critique of scepticism implicit in the cognitive solipsism of the Cartesian approach, and to illuminate the communal and controversy-oriented aspects of rational argumentation and inquiry—scientific inquiry in particular." Again, Rescher limits his discussion to "the probative mechanism in the factual domain." This book, if it were not for its price, should be a good supplement to a course in "informal" logic which focuses on argumentation rather than on mere evaluation of arguments. Plausible Reasoning provides the mechanism for evaluation of plausibility claims as distinct from probabilistic ones. The basic differences between these two types of claims are clearly discussed. "Plausibility is essentially a classificatory concept which ranks theses in terms of the standing and solidity of their cognitive basis. Plausibility grades theses by an external or extrinsic standard of the hierarchical nature of their supporting bases. It classifies propositions by the status of the evidential sources or validating principles that vouch for them. Probability weighs alternatives and evaluates theses by this relative contentual weight of the supporting considerations."—A.S.C. (shrink)
