Human mental workload is arguably the most invoked multidimensional construct in Human Factors and Ergonomics, getting momentum also in Neuroscience and Neuroergonomics. Uncertainties exist in its characterization, motivating the design and development of computational models, thus recently and actively receiving support from the discipline of Computer Science. However, its role in human performance prediction is assured. This work is aimed at providing a synthesis of the current state of the art in human mental workload assessment through considerations, definitions, measurement techniques (...) as well as applications, Findings suggest that, despite an increasing number of associated research works, a single, reliable and generally applicable framework for mental workload research does not yet appear fully established. One reason for this gap is the existence of a wide swath of operational definitions, built upon different theoretical assumptions which are rarely examined collectively. A second reason is that the three main classes of measures, which are self-report, task performance, and physiological indices, have been used in isolation or in pairs, but more rarely in conjunction all together. Multiple definitions complement each another and we propose a novel inclusive definition of mental workload to support the next generation of empirical-based research. Similarly, by comprehensively employing physiological, task-performance, and self-report measures, more robust assessments of mental workload can be achieved. (shrink)

Alexander of Aphrodisias, Aristotle’s commentator par excellence, rarely engages with Plato. In the present paper, however, we see him at work as an exegete of a passage in the _Phaedrus_ (245c5-9), in which Plato argues for the immortality of the soul based on its self-motion. In this paper, I focus on two ways in which Alexander deals with the passage. In his commentary on Aristotle’s _Prior Analytics_ (CAG II 1), Alexander employs the same approach to the _Phaedrus_ that he uses (...) with Aristotle’s treatises: he puts an informal argument expressed in ordinary language into the more formal shape of a syllogism. This does not mean that Alexander gives his approval to Plato’s theory. In fact, in his commentary on Aristotle’s _Topics_ (CAG II 2), Alexander introduces a polemical discussion of the same Platonic argument. Commenting on Aristotle’s denial that the soul is a self-moving substance (_Top_. IV 1.120b21-29), Alexander spells out the implicit reference to the _Phaedrus_ and criticizes Plato’s argument for not taking into account the difference between an accidental property of the soul and the essential characteristics by which it is defined. Plato’s theory of self-motion is partly accepted by Alexander and partly criticized. This paves the way for how the theory will be applied in the Aristotelian tradition, not to the soul, as in Plato, but to the ensouled body, either of the living being or of the heavens. (shrink)

Asclépius est un commentateur aristotélicien du VI e siècle après J.-C., qui – élève d’Ammonius – étudie à l’école néoplatonicienne d’Alexandrie en Égypte. Il réalise l’exégèse de divers passages de la Métaphysique dans lesquels Aristote attribue à Platon la doctrine de l’existence de substances mathématiques séparées (avec une position intermédiaire entre les substances intelligibles et les sensibles) et, en même temps, la critique fortement. Asclépius a une attitude de conciliation entre les perspectives platonicienne et aristotélicienne. D’une part, il défend la (...) doctrine de l’existence de substances mathématiques séparées du monde sensible et supérieures à lui, et ce faisant il s’aligne sur la défense de la doctrine platonicienne déjà opérée par les néoplatoniciens Syrianus et Proclus. Cependant, d’autre part, il adopte aussi la position aristotélicienne et celle d’Alexandre d’Aphrodise, si bien qu’il existe aussi des entités mathématiques qui ne sont pas des substances, mais des caractéristiques mathématiques formelles immanentes au sensible. Enfin, les entités mathématiques sont aussi de simples concepts mentaux obtenus par abstraction du sensible. En parlant d’entités mathématiques non substantielles, Asclépius s’aligne sur Aristote et son commentateur peripatéticien Alexandre. Asclépius, grâce à une vision hiérarchisée de la réalité, peut admettre trois types d’entités mathématiques, de sorte que chaque type inférieur est une copie atténuée de celui qui lui est supérieur.

Il brano del "Fedro" (269el-270c5) in cui è menzionato Ippocrate e il suo metodo è uno dei più controversi dell'opera platonica. Alcuni studiosi si sono serviti degli scolî antichi al dialogo, tramandati sotto il nome del neoplatonico Ermia (V sec. d. C.), per sostenere che il metodo in questione non implica un'indagine preliminare dell'universo. È tuttavia utile (oltreché finora intentato) ripercorrere quanto l'esegeta neoplatonico dice a proposito dell'intero brano in questione per constatare come egli, al contrario, ne fornisca un'interpretazione cosmologica, (...) sulla base della significazione tecnica di ἡ ὅλη ψυχή come "anima dell'universo". In ogni caso l'esegesi di Ermia risulta essere non una semplice parafrasi grammaticale del testo platonico, ma anche una sua riformulazione filosofica nei termini della dottrina neoplatonica, la quale è estremamente complessa anche nel caso dell'anima umana.

Les preuves de l’immortalité de l’âme, qui sont un des thèmes cen­traux de l’enseignement de Platon, ont fait l’objet d’une réflexion d’ordre logique et formel sur la manière dont elles sont (ou devraient être) exprimées. En particulier l’argument en faveur de l’immortalité de l’âme contenu dans le Phèdre (245c5-246a2), fondé sur la notion d’âme automotrice et principe de mouve­ment, a été assidûment analysé, pour ce qui est de sa formulation, par plusieurs représentants de la tradition platonicienne (Alcinoos, Hermias d’Alexandrie), ainsi (...) qu’à l’intérieur de la tradition péripatéticienne (Alexandre d’Aphrodise). Par conséquent, il représente, à l’avis de l’auteur, un point privilégié d’observation de la façon dont les platoniciens s’approprient la logique aristotélicienne et récri­vent, à partir de l’époque impériale, certains arguments platoniciens. En outre, il apparaît qu’Alexandre d’Aphrodise, bien qu’étant de tradition péripatéticienne, a grandement contribué à la reformulation des arguments de Platon selon les canons de la logique aristotélicienne par les platoniciens contemporains et posté­rieurs. Il semble aussi qu’Hermias, dans ses scholies sur le Phèdre, réagit juste­ment à certaines affirmations d’Alexandre. Dans cet article, on montre quels sont les points de contact ainsi que les différences dans la réécriture analytico-syllogistique de l’argument du Phèdre en faveur de l’immortalité de l’âme par Alcinoos et Hermias, sans négliger l’apport d’Alexandre.

Zalamea’s book is as original as it is belated. It is indeed surprising, if we give it a moment’s thought, just how greatly behind schedule philosophical reflection on contemporary mathematics lags, especially considering the momentous changes that took place in the second half of the twentieth century. Zalamea compares this situation with that of the philosophy of physics: he mentions D’Espagnat’s work on quantum mechanics, but we could add several others who, in the last few decades, have elaborated an extremely (...) timely philosophy of contemporary physics (see for example Bitbol 2000; Bitbol et al. 2009). As was the case in biology, philosophy – since Kant’s crucial observations in the Critique of Judgment, at least – has often “run ahead” of life sciences, exploring and opening up a space for reflections that are not derived from or integrated with its contemporary scientific practice. Some of these reflections are still very much auspicious today. And indeed, some philosophers today are saying something truly new about biology... (shrink)

Du point de vue de la logique cognitive, il n’est pas si facile qu’on le croit de récuser la rationalité des théories du complot. Les dénonciateurs du conspirationnisme partagent souvent une même conception simpliste de la vérité avec ceux auxquels ils croient s’opposer. Cet article suggère que c’est plutôt du côté d’une bifurcation écologique radicale qu’on pourra trouver une alternative réelle au tourniquet dans lequel sont pris ensemble conspirationnistes et anti-conspirationnistes.

In his commentary on Plato’sCratylus, Proclus interprets the dialogue not as a mere work on logic or linguistics, but as having a full psychological and theological import.Late ancient Platonists had already proposed a similar reading for another Platonic dialogue,i.e.theParmenides. In that case too they rejected the logical interpretation, and aimed to find in the text the description of the hierarchy of reality, particularly of the highest beings. As a result, theParmenideswas seen as the accomplished expression of Plato’s theology.Proclus too draws (...) a comparison between theCratylusand theParmenidesin order to stress their theological significance. He also contrasts Plato’s dialectic with Aristotle’s dialectic. Proclus’ interpretation of dialectic is best understood if it is compared to the doctrines of his master Syrianus and of one of his co-disciples,i.e.Hermeias, at the Platonic school of Athens in the 5th centuryad.Contrary to what is sometimes assumed, in this milieu Platonists were not always committed to the task of reconciling the philosophies of Plato and Aristotle. As it happens, they could strongly disagree with and even attack Aristotle, and side with Plato. In particular, they greatly valued Plato’s dialectic, which they viewed as the correct form of reasoning and at the same time as a theory of the utmost theological significance. On the other hand, Aristotle’s dialectic was considered as “bare” logic,i.e.as a mere set of logical rules and arguments with no specific contents.On the basis of a problematicCratylus’passage Proclus defends a theory of truth according to which not only propositions, but also names can be true or false. This allows him to view names as substitutes of propositions. This is particularly the case in the application of the four dialectical methods of definition, division, demonstration and analysis. Proclus’ approach arguably provides a basis—to pagan as well as Christian tradition—for the study of divine names as a part of theology, for the name of a god is held to reveal its attributes.

La cognition humaine paraît étroitement liée à la structure de l'espace et du temps relativement auxquels le corps, le geste, l'intelligibilité semblent devoir se déterminer. Pourtant, ce qui, après les approches physico-mathématiques de Galilée et de Newton, fut caractérisé par Kant comme formes de l'intuition sensible, n'a cessé au cours des siècles qui suivirent de se trouver remis en cause dans leur saisie première par les développements théoriques. En mathématiques d'abord, avec les géométries non-euclidiennes, en physique ensuite, où relativité générale (...) puis théories quantiques et critiques ont dû remanier profondément l'objectivité de ces concepts pour en faire des catégories, certes toujours aussi essentielles, mais de plus en plus contre-intuitives, et maintenant en biologie où la temporalité, notamment, et la causalité se révèlent largement différentes de celles de la physique. C'est ce que nous tentons de présenter et de discuter dans ce texte en vue d'en dégager la pertinence pour la cognition elle-même. (shrink)

Since the discovery of incommensurability in ancient Greece, arithmeticism and geometricism constantly switched roles. After ninetieth century arithmeticism Frege eventually returned to the view that mathematics is really entirely geometry. Yet Poincaré, Brouwer, Weyl and Bernays are mathematicians opposed to the explication of the continuum purely in terms of the discrete. At the beginning of the twenty-first century ‘continuum theorists’ in France (Longo, Thom and others) believe that the continuum precedes the discrete. In addition the last 50 years witnessed (...) the revival of infinitesimals (Laugwitz and Robinson—non-standard analysis) and—based upon category theory—the rise of smooth infinitesimal analysis and differential geometry. The spatial whole-parts relation is irreducible (Russell) and correlated with the spatial order of simultaneity. The human imaginative capacities are connected to the characterization of points and lines (Euclid) and to the views of Aristotle (the irreducibility of the continuity of a line to its points), which remained in force until the ninetieth century. Although Bolzano once more launched an attempt to arithmetize continuity, it appears as if Weierstrass, Cantor and Dedekind finally succeeded in bringing this ideal to its completion. Their views are assessed by analyzing the contradiction present in Grünbaum’s attempt to explain the continuum as an aggregate of unextended elements (degenerate intervals). Alternatively a line-stretch is characterized as a one-dimensional spatial subject, given at once in its totality (as a whole) and delimited by two points—but it is neither a breadthless length nor the (shortest) distance between two points. The overall aim of this analysis is to account for the uniqueness of discreteness and continuity by highlighting their mutual interconnections exemplified in the nature of a line as a one-dimensional spatial subject, while acknowledging that points are merely spatial objects which are always dependent upon an extended spatial subject. Instead of attempting to reduce continuity to discreteness or discreteness to continuity, a third alternative is explored: accept the irreducibility of number and space and then proceed by analyzing their unbreakable coherence. The argument may be seen as exploring some implications of the view of John Bell, namely that the “continuous is an autonomous notion, not explicable in terms of the discrete.” Bell points out that initially Brouwer, in his dissertation of 1907, “regards continuity and discreteness as complementary notions, neither of which is reducible to each other.”.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Fabuler la fin du monde: La puissance critique des fictions d’apocalypse by Jean-Paul EngélibertCyril CamusJean-Paul Engélibert. Fabuler la fin du monde: La puissance critique des fictions d’apocalypse [Fabulating the end of the world: The critical power of apocalypse fiction]. Paris: Éditions La Découverte, 2019. 239 pp. Print. 20€. ISBN 978-2-348-03719-1.Jean-Paul Engélibert is a well-established expert on apocalyptic and postapocalyptic fiction. His exploration of the genre thus far includes (...) the monograph Apocalypses sans royaume: Politique des fictions de la fin du monde, XX–XXIe siècles (2013), numerous articles, as well as the essay collection L’Apocalypse: Une imagination politique, XIXe–XXIe siècles (2018), which he co-edited. In his latest book, Fabuler la fin du monde, he returns to several texts and aspects of the genre previously covered, delving deeper into what he calls “fictions of the end of the world.” In the ten chapters, gathered in five parts, he approaches his subject as a seasoned scholar in the field of comparative literature, and his analysis draws from comparisons between modern fiction’s representation of apocalypse and biblical literature’s visions of apocalypse and messianism. The book also offers ecocritical insights into the specter of Anthropocenic manifestations in fiction, with reflections on the interrelated genres of utopia and dystopia, theories of cinema, and philosophical writings on the catastrophic history of the twentieth and twenty-first centuries.The range of fictional works discussed is wide, including Jean-Baptiste Cousin de Grainville’s Le dernier homme (1805); Mary Shelley’s Frankenstein (1818); Émile Souvestre’s Le monde tel qu’il sera (1846); Didier de Chousy’s Ignis (1883); Robert Merle’s Malevil (1972); José Saramago’s Blindness (1995); Antoine Volodine’s Minor Angels (1999); Don DeLillo’s Cosmopolis (2003); Cormac McCarthy’s The Road (2006); Céline Minard’s Le dernier monde (2007); Davide [End Page 163] Longo’s The Last Man Standing (2010); and Margaret Atwood’s MaddAddam trilogy (Oryx and Crake [2003], The Year of the Flood [2009], and MaddAddam [2013]). Engélibert also touches on feature-length movies such as Stanley Kramer’s On the Beach (1959), Lars von Trier’s Melancholia (2011), Abel Ferrara’s 4:44 Last Day on Earth (2012), and Mamoru Oshii’s Ghost in the Shell (1995), as well as on other literary and audiovisual fictions, such as E. M. Forster’s short story “The Machine Stops” (1909), Edward Bond’s dramatic trilogy The War Plays (1985), and the first season (2014) of Damon Lindelof and Tom Perrotta’s TV series The Leftovers (2014–17).Engélibert’s exegeses of the genre build around two aspects of the evolving relationship of apocalyptic narratives to the context of their production. Apocalypse (in the sense of “the end of the world” rather than the etymological sense of “revelation”) is no longer primarily a religious myth: the creation and use of the atomic bomb during the Second World War, the theorization of the Anthropocene, and the mainstreaming of concerns over climate change have made the term “apocalypse” a very real, tangible prospect for the future. Engélibert relies on Günther Anders’s Die atomare Drohung (1981) to highlight the importance of the A-bomb in bringing home the reality of potential annihilation to people’s collective consciousness. Yet his second contextual/historical point is that the Anthropocene (albeit unnamed at the time) actually started with the Industrial Revolution, and that thinkers and polemicists such as Charles Fourier or Eugène Huzar, as well as contemporary fiction writers, were already acknowledging the environmental impact of humans and their economic/industrial/technological activity as threats to human and nonhuman life, and to the health of the planetary system itself.1Citing the work of Jean-Baptiste Fressoz and Christophe Bonneuil on the history of climate science, Engélibert analyzes in detail several nineteenth-century novels (namely Le Dernier homme, Frankenstein, Le monde tel qu’il sera, and Ignis) and one early-twentieth-century story (Forster’s “The Machine Stops”) that denounce the harm that the idol of the time, Progress, was already wreaking on nature and human life...

Este artigo tem como propósito reconstituir o sentido conferido por D. Luciano Mendes de Almeida (1930-2006), bispo-auxiliar de São Paulo e arcebispo de Mariana, secretário e presidente da CNBB além de vice-presidente do CELAM, à sua própria trajetória biográfica. Verifica-se que, se cotejada com balizas culturais contemporâneas, tal configuração de si porta contornos aparentemente paradoxais: ao invés de fortalecer uma identidade pessoal, ela pressupõe uma dinâmica antropológico-religiosa de autoesvaziamento, concomitante a uma atuação mediadora em prol de relações ternárias entre Deus, (...) os sujeitos e si mesmo, processo denominado por D. Luciano como “interiorização da figura Jesus Cristo”. Com o suporte teórico provindo da semiótica e da história religiosa, tal interiorização é aqui compreendida como um programa narrativo específico, que adquiriu formas singulares ao longo dos séculos, com destaque à espiritualidade inaciana, mas preservando sua concepção como um agir, pela fé, em nome da competência atribuída a um Outro. Sugere-se ainda que, na atualidade, a interiorização possa ser aproximada do relato de testemunho, face ao engajamento ético por ela suscitado, que reconfigura o sujeito no compartilhar de experiências vividas e postas em discurso. Palavras-chave: D. Luciano Mendes de Almeida. Biografia. Interiorização. Testemunho.: This article aims at reconstructing the meaning given by D. Luciano Mendes de Almeida (1930-2006), to his own biographical trajectory. D. Luciano was auxiliary bishop of Saint-Paul and Archbishop of Mariana, secretary and president of the CNBB, and also vice president of CELAM. The configuration he made of himself appears to be paradoxical: instead of strengthening a personal identity, it assumes a dynamic anthropological and religious self-emptiness and a mediating performance in favor of ternary relations between God and the subject itself, a process called by the Archbishop as the "internalization of the figure Jesus Christ." With a theoretical support coming from semiotics and religious history, this process of internalization is understood in this article as a specific narrative program which has acquired unique forms over the centuries, with emphasis on Ignatians spirituality, while preserving its conception as an act of faith on behalf of the competency given to an Other. The article also suggests that ,nowadays, that internalization of the figure of Jesus Christ approaches the reported testimony, given the ethical engagement raised by it, which reconfigures the subject in the sharing of experiences of life that are brought into discourse.

O artigo discute passagens importantes da obra de Santo Agostinho e argumenta que muitas são as antecipações de teses comumente atribuídas a Descartes. Entre elas, uma clara antecipação à célebre fórmula “penso, logo existo” na obra do Bispo de Hipona, assim como de outras teses importantes distribuídas ao longo de sua obra. Na segunda parte, culmina o texto com outro dado praticamente desconhecido: o fato de que o estilo meditativo empregado por Descartes também já fora antecipado por uma autora (...) cuja obra era amplamente conhecida na Europa da metade do século XVI e do século XVII. Trata-se da freira Teresa D’Ávila que fora canonizada quando o jovem Descartes estudava com os jesuítas em La Flèche. Levanta-se, assim, a necessidade de repensarmos a historiografia acadêmica à que a maioria de nós fomos submetidos quando iniciamos os estudos filosóficos sem termos sido expostos às verdadeiras fontes das teses centrais que encontramos em muitas obras clássicas do pensamento filosófico.

Este estudo visa demonstrar de que modo os romancistas antigos, especialmente Cáriton de Afrodísias (séc. I d.C.?) e Longo de Lesbos (séc. II d.C.?), conferem a eros características semelhantes àquelas que lhe são atribuídas por Platão em seus diálogos Banquete e Fedro. Especialmente, defende-se que os métodos e questionamentos desenvolvidos pelos romancistas são semelhantes aos de Platão: "Quem é Eros? Quais são seus efeitos? Ou, ainda, o que ele nos traz?". Em última instância, a pesquisa se coloca como uma (...) reflexão sobre os influxos da filosofia na literatura, questionando a suposta diferenciação rígida que as separa no mundo clássico.

La novela griega, género polifacético de ficción en prosa, que floreció del siglo I al IV d.C., tuvo su continuación en la literatura bizantina. La trascendencia de la novela llegó al Renacimiento con Longo y su Dafnis y Cloe, que influenció obras como la Arcadia de Sanazzaro, en Italia, o la Diana, de Jorge de Montemayor, en España; y tuvo cierto influjo en la Galatea de Cervantes e incluso en El Quijote. También la Arcadia de Sidney es tributaria del (...) tema y la Astrea de Honoré d' Urfé, en Francia, refleja también este efecto. En esta comunicación quiero destacar la influencia de la novela griega en La Tempestad, comedia en cinco actos de Shakespeare, que revela gran afinidad con la novela de amor y aventuras, así como con la novela utópica. The Greek novel, a multifaceted fiction genre in prose, flourished between the first and the fourth Century A.D., had its continuation into the Byzantine literature. The significance of the Greek novels reached the Renaissance with Longus and his Daphnis and Chloe, that influenced Sanazzaro's Arcadia in Italy, or Jorge de Montemayor's Diana, in Spain. It also had a certain influence in Cervantes' Galatea and even in his Quijote. Sidney's Arcadia is also tributary to the theme, such as Honoré d' Urfé's Astrea, in France. In this paper I want to point out the influence of the Greek novel in Shakespeare I will focus in The Tempest, comedy in five acts, that reveals great affinity with the Greek novel of love and adventures of Longus, Xenophon of Ephesus and Achilles Tatius, as well as in the utopian novel.

R.G. Collingwood (1889-1943) was an English philosopher, historian and practicing archaeologist. His work, particularly in the philosophy of action and history, has been profoundly influential in the 20th and 21st century. Although the importance of his work is indisputable, this is the first book to consider how and why it actually matters. Giussepina D'oro considers the importance of Collingwood as a thinker who thinks kaleidoscopically and, unlike lots of contemporary philosophers, refuses to focus on narrow, technical interests but instead, observes (...) the whole world of thought. Why Collingwood Matters revives Collingwood's conception of the role and character of philosophical analysis and shows how it informs his understanding of the mind, what it means to act, and what it means to understand the past historically. It also argues for the relevance of his metaphilosophical approach to the challenge posed by the Anthropocene and the global environmental crisis. Both an elucidation of Collingwood's thought and a lively exploration of it's contemporary relevance, Why Collingwood Matters provides a much-needed examination of a 20th-century polymath. (shrink)

O presente artigo debruça-se na crítica de Diderot à Helvétius. Apesar da crítica ser feita pontualmente a cada trecho comentado do livro De l’Homme de Helvétius, consideramos que ela possui um núcleo principal, que é a diferente concepção de materialismo dos autores e suas consequências para o que ambos anseiam para a sociedade. Por isso, investigamos o que há no horizonte do materialismo de Helvétius e de Diderot no que concerne à educação e como, apesar de estarem próximos no ponto (...) de partida, o materialismo, seu norte é diferente. A escolha do tema da educação justifica-se por tratar-se de algo que ultrapassa a teorização filosófica e busca inserção prática na sociedade, mostrando assim não só as consequências práticas das teses materialistas como também o ideal de sociedade proposto por cada autor. Aqui, apontamos para as principais diretrizes sobre a construção de uma educação institucional em De l’Esprit (1754) e De l’Homme (1771), de Helvétius, nas Em Reflexions sur le livre De l’Esprit (1877) e Refutations suivre l’ouvrage intitule De l’Homme (1877)1, e em outras obras de Diderot. 1 As críticas reunidas de Diderot foram publicadas apenas postumamente. Estima-se que a segunda, dedicada à De l’Homme foi redigida em um longo período, que coincide com a redação do Plan d’Université (1775) e Elements de Phisiologie (1875). (shrink)

A relação entre o sublime e a arte, a princípio, soa natural e certa, mas ao longo do século XVIII algumas teorias afastaram essa categoria da produção artística. Foram décadas notadamente frutíferas nas questões sobre o sublime, período em que não só o sublime recebe seu título de categoria estética como destacadamente participa das questões epistemológicas da recém cunhada disciplina Estética. Nesse cenário, alguns pensadores se voltam exclusivamente para o sublime natural. Esse artigo procurará mostrar o caminho percorrido por (...) esse conceito a partir da recepção pelos ingleses, em 1689, do tratado sobre retórica do século I d.C. intitulado Peri Hypsos, traduzido por Boileu-Despréaux como Sobre o Sublime e atribuído ao crítico grego Cassius Longinus. Visitaremos as teorias de pensadores como Joseph Addison, Edmund Burke e Immanuel Kant, que apontam para o sublime exclusivamente como contemplação da natureza, e encerraremos essa jornada na reinserção do drama trágico na categoria sublime por Friedrich Schiller. Fecha-se, dessa forma, o que chamamos aqui de “ciclo do sublime natural”, que se inicia na leitura característica dos britânicos empiristas, encontra sua mais bem acabada teoria na terceira Crítica kantiana e se encerra no trabalho teórico e literário do poeta de Weimar.

Opinion is divided about the certainty of the evidence base for gender-affirming medical interventions in youth. Proponents claim that these treatments are well supported, while critics claim the poor-quality evidence base warrants extreme caution. Psychotherapy is one of the only available alternatives to the gender-affirming approach. Discussion of the treatment of gender dysphoria in young people is generally framed in terms of two binary approaches: affirmation or conversion. Psychotherapy/exploratory therapy offers a treatment option that lies outside this binary, although it (...) is mistakenly conflated with conversion therapies. Psychotherapy does not impose restrictive gender stereotypes, as is sometimes claimed, but critically examines them. It empowers young people to develop creative solutions to their difficulties and promotes agency and autonomy. Importantly, an exploratory psychotherapeutic process can help to clarify whether gender dysphoria is a carrier for other psychological or social problems that may not be immediately apparent. Psychotherapy can therefore make a significant contribution to the optimal, ethical care of gender-dysphoric young people by ensuring that patients make appropriate, informed decisions about medical interventions which carry risks of harm and have a contested evidence base.

No início do movimento psicanalítico, a Hungria foi um dos países pioneiros dentre os que acolheram e propagaram a psicanálise. Sándor Ferenczi, figura principal de desenvolvimento da psicanálise no país, abraçou a causa psicanalítica e se tornou um dos mais importantes teóricos de sua história. Responsável pela criação da Associação Psicanalítica Internacional, fundaria também a Sociedade Húngara de Psicanálise, instituição reconhecida pela originalidade de suas propostas. Além de Ferenczi, Melanie Klein, Michael e Alice Balint, Géza Roheim, dentre outros, foram seus (...) membros. Neste estudo de caráter histórico, o intuito é retomar todo o caminho trilhado pela instituição húngara, desde sua fundação até sua dissolução, em 1949. A identidade e o “espírito” investigativo daquela instituição se perpetuariam ao longo da história psicanalítica, influenciando, direta ou indiretamente, grandes escolas e teóricos da psicanálise, como D. W. Winnicott e alguns pensadores das escolas americanas e francesas. Palavras-chave: psicanálise; história da psicanálise; sociedade húngara de psicanálise; instituições psicanalíticas; Sándor Ferenczi.: Hungary was a place where psychoanalysis founded a great support and development at the beginning of psychoanalytical movement. Sándor Ferenczi, leading figure of psychoanalytical increase in the country, embraced the psychoanalytic cause and became one of its most important theorists and thinkers in history. Responsible for the foundation of the International Psychoanalytical Association, also created the Hungarian Psychoanalytical Society, an institution recognized for the originality of their proposals. Besides Ferenczi, Melanie Klein, Michael and Alice Balint, Géza Roheim, among others, were its members. In this historical study, the purpose is to resume the entire path taken by the Hungarian institution, from the foundation to its dissolution in 1949. The identity and the investigative “spirit” of that institution perpetuate throughout psychoanalytical history, influencing, directly or indirectly, great schools and theorists of psychoanalysis, eg, D. W. Winnicott and some thinkers of American and French schools. Keywords: psychoanalysis; psychoanalytical history; hungarian psychoanalytical society; psychoanalytical institutions; Sándor Ferenczi.

Husserl und die transzendentale Intersubjektivität analyses the transcendental relevance of intersubjectivity, and argues that an intersubjective transformation of transcendental philosophy can already be found in phenomenology, especially in Husserl. Husserl eventually came to believe that an analysis of transcendental subjectivity was a conditio sine qua non for a phenomenological philosophy. Drawing on both published and unpublished manuscripts the book examines his reasons for this conviction and delivers a detailed analysis of his radical and complex concept of intersubjectivity, showing that precisely (...) his reflections on transcendental intersubjectivity are capable of clarifying his phenomenological core-concepts, thus making possible a new understanding of his philosophy. Against this background the book then attempts to establish to what extent the phenomenological approach to intersubjectivity can contribute to the current discussions of intersubjectivity. This is achieved through a systematic confrontation with the language-pragmatical positions of Apel and Habermas. Die Abhandlung untersucht die transzendentale Relevanz der Intersubjektivität und zeigt, daß eine intersubjektive Transformation der Transzendentalphilosophie schon innerhalb der Phänomenologie - besonders der Husserlschen - zu finden ist. Husserl gelangte zu der Auffassung, daß eine Analyse und Einbeziehung der transzendentalen Intersubjektivität als conditio sine qua non für eine phänomenologische Philosophie zu betrachten sei. Die Gründe, die Husserl zu dieser Überzeugung führten, werden herausgearbeitet. Dabei weist die Analyse des radikalen und komplexen Begriffs der Intersubjektivität auf, daß erst seine Überlegungen zur transzendentalen Intersubjektivität viele phänomenologische Grundbegriffe ins rechte Licht stellen können und darüber hinaus ein neues Grundverständnis seiner Phänomenologie ermöglichen. Vor diesem Hintergrund wird die Frage, inwieweit die Phänomenologie zur gegenwärtigen Intersubjektivitätsdiskussion beitragen kann, durch eine systematische Auseinandersetzung mit der sprachpragmatischen Intersubjektivitätstheorie von Apel und Habermas beantwortet.

Resumo: O presente artigo visa apresentar, sistematizar e analisar, à luz da teoria social crítica, as ações desenvolvidas pelo NESEF (Núcleo de Estudos e Pesquisas sobre o Ensino de Filosofia) ao longo de duas décadas de existência na Universidade Federal do Paraná - UFPR. Procura situar e referenciar as diferentes atividades desenvolvidas coletivamente no campo da pesquisa e da extensão. Parte do entendimento que a Filosofia só é Filosofia à medida que ela se nega e, por conseguinte, se realiza; (...) e ela só se realiza na prática social, cultural e política na e através da ação coletiva. Pretende mostrar o conjunto de ações desenvolvidas (em rede) pelo NESEF que, com o passar do tempo, assume a condição de “intelectual orgânico-coletivo”. Por se tratar de uma descrição de atividades estreitamente ligadas à atuação do autor, o texto revelará sua trajetória profissional entrelaçada ao seu “jeito de caminhar” diante dos embates teórico-práticos do campo acadêmico formando, assim, um contínuo movimento de ondas tensas (laços e nós) que encontraram na ação conjunta – na práxis coletiva – um terreno fértil. Palavras-chave: NESEF; Intelectual Orgânico; Educação Filosófica The NESEF as an organic-collective intellectual: from head to toe Abstract: This article aims to present, systematize and analyze, in the light of critical social theory, the actions developed by NESEF (Center for Studies and Research on Philosophy Teaching) over two decades at the Federal University of Paraná – UFPR. It seeks to point out and reference the different activities developed collectively in the field of research and extension. It is considered that Philosophy is Philosophy only insofar as it negates itself and, consequently, realizes itself; and it is only realized in social, cultural and political practice in and through collective action. It is intended to show the set of actions developed (in a network) by the NESEF which, over time, assumes the condition of “organic-collective intellectual”. As it is a description of activities closely linked to the author's work, the text reveals his professional trajectory intertwined with his "way of walking" in the face of theoretical-practical clashes in the academic field, thus forming a continuous movement of tense waves (ties and knots) that found fertile ground in joint action – in collective praxis. Key words: NESEF; Organic Intellectual; Philosophical Education Le NESEF comme intellectuel organique-collectif : de la tête aux pieds Résumé: Cet article vise à présenter, systématiser et analyser, à la lumière de la théorie sociale critique, les actions développées par le NESEF (Centre d'Études et de Recherche sur l'Enseignement de la Philosophie) pendant deux décennies à l'Université Fédérale du Paraná – UFPR. Il cherche à situer et référencer les différentes activités développées collectivement dans le domaine de la recherche et de l'extension. Il est entendu que la Philosophie n'est la Philosophie qu'en tant qu'elle se nie elle-même et, par conséquent, se réalise; et elle ne se réalise que dans la pratique sociale, culturelle et politique dans et par l'action collective. Il vise à montrer l'ensemble des actions développées (en réseau) par la NESEF qui, au fil du temps, assume la condition d'« intellectuel organique-collectif ». Comme il s'agit d'une description d'activités étroitement liées au cours de travail de l'auteur, le texte révèle sa trajectoire professionnelle entrelacé à sa "façon de marcher" face aux affrontements théoriques-pratiques du champ académique, formant ainsi un mouvement continu d'ondes tendues (liens et nœuds) qui ont trouvé un terreau fertile dans l'action commune – c'est à dire, dans la praxis collective.

RESUMO:Na Carta a d’Alembert, Rousseau se coloca contra a ideia de um teatro enquanto instrumento de educação moral, porém, o posicionamento do filósofo não está em colocar essa atividade lúdica de ordem moral na categoria de atividade imoral, mas na de atividade artificial, e, talvez, isso gerasse efeitos imorais. Todavia, é preciso observar os verdadeiros efeitos do teatro, a partir de alguns argumentos que Rousseau resolve construir e analisá-los, contudo, apenas se trouxesse à tona a crítica de Rousseau ao romance, (...) na Carta a d’Alembert, que tem como contexto “a ideia negativa de privatização da cena”, pois o teatro destina uma excessiva importância à descrição do amor, obviamente, exagerando na representação, naquilo que é romanesco. Porém, se, na Carta a d’Alembert, o filósofo não expressa de forma direta que a teorização sobre o teatro também equivale ao romance, na Nova Heloísa, ou seja, no próprio romance, o autor faz essa ratificação, ao importar um longo comentário sobre o teatro que estava na Carta, afirmando que considera o mesmo da própria cena quanto à maioria dos novos escritos. O cidadão genebrino ataca os romances indiretamente e viceversa, porque é observado que tudo aquilo que diz sobre uma arte se aplica quase que integralmente a outra arte. E, como um povo galante deseja amor e polidez, Rousseau resolve fixar alguns termos, na tentativa de explicar suas críticas e argumentar a coerência de seu posicionamento, já que, se, em geral, a cena é um quadro das paixões humanas, cujo original está nos corações, se o pintor, porém, não tiver cuidado de acariciar suas paixões, os espectadores logo ficarão desgostosos e não desejarão mais se ver sob um aspecto que fizesse com que desprezassem a si mesmos. E pontua que essa linguagem não tem mais sentido, em seu século, pois é preciso falar as paixões, esforçando-nos para usar uma que melhor se compreenda, talvez o romance. ABSTRACT:In theLetter to d’Alembert, Rousseau argues against the idea of theater as a moral instrument of education. However, the position of the philosopher is not one of putting this playful activity in the category of immoral activity, but in the category of an artificial activity that perhaps generates immoral purposes. It is necessary to observe the true effect of the theater on the basis of some arguments that Rousseau decides to construct. These are analyzed here, bringing to the fore Rousseau’s critique of the novel in theLetter to d’Alembert. The letter has as its context “the negative idea of privatization of the scene”, as the theater gives an excessive importance to the description of love, obviously exaggerating the representation of romance. If, in theLetter to d’Alembert, the philosopher does not directly express that theorizing about the theater is equivalent to the novel, in theNouvelle Héloïse, that is, in the novel itself, the author does this. He adds to the novel a long commentary on the theater that was in theLetter, stating that he considers the theatrical scene itself to be the same as most new writing. He attacks novels indirectly, as well as the theatre, observing that everything said about one art applies almost entirely to another art. As a gallant people want love and politeness, Rousseau decides to fix certain terms in an attempt to explain his criticism and argue the consistency of his position. In general, the scene is a picture of human passions whose original is in the heart; if the painter is not careful in stroking these passions, spectators will soon become disgusted, not wanting to see themselves in such a way that they despise themselves. Rousseau points out that this language has no more meaning in his century, as it is necessary to speak the passions, striving to use language that best understands the passions, such as, perhaps, that of the novel.

Enciclopédia não está entre os termos mais conhecidos de Michel Foucault. Todavia, ao olhar com atenção para algumas ocorrências desse termo ao longo de sua carreira, com uma especial ênfase aos anos de 1960 e 1970, algo se revela ao leitor atento. O intuito desse texto é discernir esse termo no vocabulário foucaultiano, mostrando sua dupla face. Se por um lado, Foucault se refere tecnicamente à Enciclopédia editada por Denis Diderot e Jean D’Alembert; por outro, ele recorre ao termo (...) sugerindo outra prática que não simplesmente elabora um memorial de nossos saberes, mas ultrapassa essa fronteira na direção do que ele chamará de heterotópico. No primeiro momento, o caráter crítico da abordagem levará a considerações sobre os limites do projeto enciclopédico, e as consequências práticas das políticas de memória e esquecimento que ele implica. Num segundo momento, a partir de fontes importantes como Nietzsche, Freud e Marx, compreenderemos as possibilidades de uma nova dobra na história das técnicas de interpretar, em busca de uma ressignificação foucaultiana das enciclopédias.

Considerações sobre a impossibilidade de definir o homem a partir de Descartes Procuramos, neste texto, pensar o significado da rejeição da tradicional definição de homem efetuada por Descartes, quando tenta entender o que somos. Essa rejeição é resultado de um novo método de filosofar, que poderíamos designar como via das ideias – aquela que parte das forças do próprio espírito para examinar tudo o que ocorre nele e em qualquer outra coisa, evitando usar de pressuposições. A fim de marcar essa (...) diferença de perspectiva e a reiterada disposição do filósofo francês em elaborá-la, apontamos a limitação da noção de conceito – seja aquela da tradição aristotélica-escolástica, seja a pós-cartesiana, fortemente marcada pela representação científica – para dar conta da problemática do fenômeno humano. Nesse sentido, insistimos na riqueza e amplitude da noção de ideia – elaborada e reelaborada ao longo dos anos pelo filósofo – para enfrentar esse complexo fenômeno. Uma vez que o homem não é uma substância, a manifestação dos seus aspectos é sempre adjetiva, podendo qualificá-lo sem, contudo, propiciar a sua compreensão. Essa dificuldade de apreensão exige, portanto, que o estudo da ideia de homem explore até o limite a própria racionalidade humana Palavras-chave: Descartes; Homem; Ideia; Conceito; Definição. Considerations on the impossibility of defining man based on Descartes Abstract: The aim of this text is to reflect on the meaning of the rejection of the traditional definition of man performed by Descartes when he attempts to understand what we are. This rejection is the result of a new method of philosophizing, which we may designate as the way of ideas—that which emerges from the forces of one’s own spirit to examine all that occurs within it and in any other thing, avoiding the use of presuppositions. To highlight this difference of perspective and the reiterated willingness of this French philosopher in elaborating it, we indicate the limitation of the notion of concept—whether that of the Aristotelian-Scholastic tradition or the post-Cartesian tradition, strongly characterized by scientific representation—to deal with the problematic of the phenomenon of the human. In this respect, we stress the richness and amplitude of the notion of idea, elaborated and re-elaborated over years by this philosopher, to address this complex phenomenon. Since man is not a substance, the manifestation of his aspects is always adjectival, allowing qualification without, however, providing comprehension. This difficulty of perception therefore requires that the study of the idea of man explore human rationality itself to the greatest extent. Keywords: Descartes; Man; Idea; Concept; Definition. Considérations sur l'impossibilité de définir l'homme à partir de Descartes Resumé: On se propose, dans ce texte, de réfléchir sur le sens du rejet de la définition traditionnelle de l'homme faite par Descartes, lorsqu'il tente de comprendre ce que nous sommes. Ce rejet est le résultat d'une nouvelle méthode de philosopher, que nous pourrions désigner comme la voie des idées - celle qui part des forces de l'esprit lui-même pour examiner tout ce qui se passe en lui et en toute autre chose, en évitant d'utiliser des présupposés. Pour marquer cette différence de perspective et la disposition réitérée du philosophe français dans son élaboration, nous soulignons la limitation de la notion de concept - soit celle de la tradition aristotélicienne-scolastique, soit celle post-cartésienne, fortement marquée par la représentation scientifique - pour rendre compte de la problématique du phénomène humain. En ce sens, nous insistons sur la richesse et l'amplitude de la notion d'idée - élaborée et retravaillée au fil des années par Descartes - pour faire face à ce phénomène complexe. Une fois l'homme n'est plus une substance, la manifestation de ses aspects reste toujours adjective, pouvant le qualifier sans toutefois favoriser sa compréhension. Cette difficulté d'appréhension exige donc que l'étude de l'idée de l'homme explore jusqu'à la limite la rationalité humaine elle-même. Mots-clés: Descartes; Homme; Idée; Concept; Définition.

O século XVII revelou-se bastante positivo no tocante ao enriquecimento do hagiológio lusitano, tendência que se conseguiu manter activa até inícios de Setecentos. Para além da canonização da Rainha Santa Isabel (1625), em 1671, o Papa Clemente X estende o culto de Gonçalo de Amarante (beatificado em 1561) à Ordem dos Pregadores e a todo o reino de Portugal, com missa e ofício litúrgicos próprios.Seguir-se-ão outros processos de infantas portuguesas, mais prolíferos em termos de produção artística e iconográfica, que decorrem (...) na viragem para o século XVIII. Primeiro, o da Princesa Santa Joana (1693) e, alguns anos depois, o das filhas de D. Sancho I – Teresa, Sancha (1704) e Mafalda (processo iniciado em 1700, embora beatificada apenas em 1792). Estes processos, independentemente do seu sucesso, motivaram uma significativa produção de novas formas de representação. A proximidade com o poder papal, e com os centros de decisão, como o da Sagrada Congregação dos Ritos, levou consequentemente à opção por uma produção romana no tocante à origem das novas imagens.Apesar de motivadas por intuitos de ordem religiosa, no sentido de suscitar a devoção e divulgar o culto, estas encomendas contribuíram não só para a criação de uma nova iconografia, como para o desenvolvimento de novos conceitos estilísticos e de vertentes do gosto. De facto, elas acabam por definir a preponderância das correntes italo-romanas, que marcariam o estilo predominante da pintura portuguesa, ao longo da centúria seguinte. (shrink)

En redonnant vie au problème de la transformation des formes tout au long de l'itinéraire de la pensée de Sartre - de la "philosophie pure" à la "monographie historique concrète" -, cette étude essaie de reconstituer quelques moments du processus de gestation de la synthèse sartrienne entre Philosophie, Roman et Révolution. La "monographie historique concrète" aurait-elle chez Sartre la fonction de succédané pour la "Philosophie Traditionnelle" et pour le "Roman Traditionnel"? Ce qui semble conduire l'itinéraire sartrien - de L'être et (...) le néant à L'idiot de la famille -, c'est la recherche d'une forme philosophique, littéraire et historique qui présuppose, sous-jacente, une Théorie du Roman indissolublement liée à une Théorie de la Révolution, plus précisément, à une théorie de la temporalité révolutionnaire qui recèle en elle-même la marque décisive de l'expérience politique de la Guerre, de Occupation et de la Résistance.Reativando o problema da transformação das formas ao longo do itinerário do pensamento de Sartre-da "filosofia pura" à "monografia histórica concreta"-, o presente estudo procura reconstituir alguns momentos do processo de gestação da síntese sartriana entre Filosofia, Romance e Revolução. Teria a "monografia histórica concreta", para Sartre, a função de sucedâneo da "Filosofia Tradicional" e do "Romance Tradicional"? O que parece norteara trajetória sartriana - de L'Être et le Néant a L'Idiot de la famille - é a busca de uma forma filosófica, literária e histórica que pressupõe, subjacente, uma teoria do romance indissoluvelmente ligada a uma teoria da revolução, mais precisamente, a uma teoria da temporalidade revolucionária que encerra em si mesma a marca decisiva da experiência política da Guerra, da Ocupação e da Resistência.

A couple of decades after becoming a major area of both public and philosophical concern, animal ethics continues its inroads into main- stream consciousness. Increasingly, philosophers, ethicists, professionals who use animals, and the broader public confront specific ethical issues regarding human use of animals as well as more fundamental questions about animals’ moral status. A parallel, related development is the explo- sion of interest in animals’ mental lives, as seen in exciting new work in cognitive ethology and in the plethora (...) of movies, television commercials, and popular books featuring apparently intelligent animals. -/- As we approach the turn of the twenty-first century, philosophical animal ethics is an area of both increasing diversity and unrealized poten- tial – a thesis supported by this essay as a whole. Following up on an earlier philosophical review of animal ethics (but without that review’s focus on animal research), the present article provides an updated narrative – one that offers some perspective on where we have been, a more detailed account of where we are, and a projection of where we might go. Each of the three major sections offers material that one is unlikely to find in other reviews of animal ethics: the first by viewing familiar territory in a different light (advancing the thesis that the utility-versus-rights debate in animal ethics is much less important than is generally thought); the second by reviewing major recent works that are not very well-known (at least to nonspecialists); and the third by identifying important issues that have been largely neglected.

Shepherdson [14] showed that for a discrete ordered ring I, I is a model of IOpen iff I is an integer part of a real closed ordered field. In this paper, we consider integer parts satisfying PA. We show that if a real closed ordered field R has an integer part I that is a nonstandard model of PA (or even IΣ₄), then R must be recursively saturated. In particular, the real closure of I, RC (I), is recursively saturated. We (...) also show that if R is a countable recursively saturated real closed ordered field, then there is an integer part I such that R = RC(I) and I is a nonstandard model of PA. (shrink)

Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.
