The purpose of the present paper is to reply to a misleading paper by M. Sachs entitled “Einstein's later view of the Twin Paradox” (TP) (Found. Phys. 15, 977 (1985)). There, by selecting some passages from Einstein's papers, he tried to convince the reader that Einstein changed his mind regarding the asymmetric aging of the twins on different motions. Also Sachs insinuates that he presented several years ago “convincing mathematical arguments” proving that the theory of relativity does not predict asymmetrical (...) aging in the TP. Here we give a definitive treatment to the clocks problem showing that Sachs' “convincing mathematical arguments” are non sequitur. Also, by properly quoting Einstein, we show that his later view of the TP coincides with the one derived from the rigorous theory of time developed in this paper. (shrink)

Tendo como ponto de partida a obra de René Girard, o presente artigo pretende apresentar a dimensão antropológica presente na obra deste autor, destacando a sua originalidade e novidade ao pensar o homem como animal socialmente desejante. A teoria mimética, como Girard a formula, pretende ser uma teoria que, colocando no centro da sua reflexão o desejo e a imitação, permita compreender como se estruturam as sociedades arcaicas e actuais, partindo de mecanismos marcadamente antropológicos, para afirmar que as sociedades se (...) estruturam a partir do desejo, do sacrifício e da necessidade de existência de «bodes expiatórios». A partir deste pressuposto, o sacrifício é a primeira instituição humana, com a capacidade farmacológica de preservar a sociedade e de permitir a sua subsistência no tempo. A cultura, por seu lado, emerge a partir do desejo mimético; e o mecanismo do bode expiatório, mecanismo vitimário por excelência, regula a sociedade ao solucionar as suas tensões internas. Considerando estes três conceitos – sacrifício, desejo mimético e mecanismo do bode expiatório – este artigo expõe o modo como se relacionam estes conceitos. Apesar de constatar a sua presença e eficácia na história, Girard não os legitima de jure, desvelando o segredo da sua eficácia – a ignorância inocente das vítimas – que, paradoxalmente, persiste mesmo depois de denunciada nas suas escusas razões. Posto isto, perguntemo-nos: como proteger o homem da sua própria violência? (shrink)

Este artigo resume os pontos básicos que caracterizam Habermas como um crítico da modernidade e, consequentemente, como um filósofo pós-moderno.

A cross-cultural survey experiment revealed a dominant tendency to rely on a rule’s letter over its spirit when deciding which behaviors violate the rule. This tendency varied markedly across (k = 15) countries, owing to variation in the impact of moral appraisals on judgments of rule violation. Compared with laypeople, legal experts were more inclined to disregard their moral evaluations of the acts altogether and consequently exhibited stronger textualist tendencies. Finally, we evaluated a plausible mechanism for the emergence of textualism: (...) in a two-player coordination game, incentives to coordinate in the absence of communication reinforced participants’ adherence to rules’ literal meaning. Together, these studies (total n = 5,794) help clarify the origins and allure of textualism, especially in the law. Within heterogeneous communities in which members diverge in their moral appraisals involving a rule’s purpose, the rule’s literal meaning provides a clear focal point—an identifiable point of agreement enabling coordinated interpretation among citizens, lawmakers, and judges.

This paper reflects on quality assessment and performance evaluation in higher education, namely by analysing the insufficient link between those two aspects. We start by reviewing the current state of the art regarding different processes and mechanisms of quality assessment and performance evaluation and discuss some of the major issues regarding the implementation of some of them. In particular, we analyse the current limitations regarding data collected, available and publicised on the performance of HEIs and the problems those limitations bring (...) to a fair evaluation of higher education. Through this analysis we intend to contribute to a better understanding of the mechanisms of evaluation in higher education and the way these may lead to the promotion of better quality assessment practices and institutional management.

Despite pervasive variation in the content of laws, legal theorists and anthropologists have argued that laws share certain abstract features and even speculated that law may be a human universal. In the present report, we evaluate this thesis through an experiment administered in 11 different countries. Are there cross‐cultural principles of law? In a between‐subjects design, participants (N = 3,054) were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also (...) whether there are any such laws. Confirming our preregistered prediction, people reported that such laws cannot exist, but also (paradoxically) that there are such laws. These results document cross‐culturally and –linguistically robust beliefs about the concept of law which defy people's grasp of how legal systems function in practice. (shrink)

This article seeks to analyze how the phenomenon of dance presents itself in philosophy, especially from the reflections of the German philosopher F. Nietzsche. To enhance our hypotheses, we will resort to the literary work The Steppenwolf by the German writer Hermann Hesse. We know that dance as a metaphor for thought is presented both throughout Nietzsche's work and in the aforementioned book by Hermann Hesse. Therefore, our analysis seeks to demonstrate how dance involves a situation of surrender and acceptance (...) of Life. It is about dance as a thought of overcoming oneself. This overcoming takes place in the instant. The instant when we understand Life as a movement towards its infinite possibilities. Based on the philosophical investigation, in this work, we will start by presenting the concept of dance in Nietzsche's philosophy, then we will exemplify this concept in the work of Hesse and, finally, we will demonstrate the relationship between dance, thought and affirmation of life.

Por razões de ordem, tanto técnicas, como de economia de tempo, decidi-me por adotar, em meu texto, a mesma distribuição espacial da matéria, que é a do livro analisado. Com o intuito de evitar repetições enfadonhas e/ou inúteis, trabalhei de acordo com o critério de escolha e análise crítica de casos e/ou aspectos considerados exemplares. Assim, características eventualmente presentes em diversas passagens da obra, serão abordadas e criticadas uma única vez. [...] Palavras-chave: Taylorismo; Trabalho; Capital; Resistência; Facismo.

Este artigo procura desenvolver o conceito de "crítica" no primeiro romantismo, sobretudo em seus principais representantes, Friedrich Schlegel e Novalis. A partir destes autores já não se pode falar de uma obra de arte desvinculada da reflexão sobre ela, mas, por sua vez, a própria "critica" deve se tomar arte.

Aristotle’s influence on D’Arcy Thompson was praised by Thompson himself and has been recognized by others in various respects, including the aesthetic and normative dimensions of biology, and the multicausal explanation of living forms. This article focuses on the relatedness of organic forms, one of the core problems addressed by both Aristotle’s History of Animals (HA), and the renowned chapter of Thompson’s On Growth and Form (G&F), “On the Theory of Transformations, or the Comparison of Related Forms.” We contend that, (...) far from being an incidental inspiration stemming from Thompson’s classicist background, his translation of HA played a pivotal role in developing his theory of transformations. Furthermore, we argue that Thompson’s interpretation of the Aristotelian method of comparison challenges the prevailing view of Aristotle as the founder of “typological essentialism,” and is a key episode in the revision of this narrative. Thompson understood that the method Aristotle used in HA to compare animal forms is better comprehended as a “method of transformations,” leading to a morphological arrangement of animal diversity, as opposed to a taxonomical classification. Finally, we examine how this approach to the relatedness of forms lay the foundation for a causal understanding of parts and their interconnections. Although Aristotle and Thompson emphasized distinct types of causes, we contend that they both differ in a fundamental sense from the one introduced by Darwin’s theory of natural selection, which was formulated as a solution to the species problem rather than the form problem. We conclude that Thompson’s interpretation of Aristotle’s approach to form comparison has not only impacted contemporary scholarship on Aristotle’s biology, but revitalized a perspective that has regained significance due to the resurgence of the problem of form in evo-devo.

O artigo discute o recuo da teoria instalado nos processos de formação de professores do nosso tempo. Como suporte teórico, lança mão das concepções epistemológicas de G.W.F. Hegel e de Karl Marx. Ao apresentar essas perspectivas teóricas, a partir de obras dos próprios autores, advoga que a despeito de partirem de intencionalidades político-sociais antagônicas, ambos levam-nos a constatar que os padrões de formação pedagógica preponderantes atualmente não ultrapassam os níveis mais imediatos e indeterminados do processo de elaboração do saber. Por (...) fim, conclui que a aversão à teoria, em favor da suposta valorização de uma formação prática para a prática, afunda no praticismo, fragiliza a práxis, confina a formação nos limites do senso comum e afasta a Pedagogia do nível do conhecimento científico.

This article aims to offer a fresh analysis of two passages in the extensive necromancy episode in Lucan's Bellum Ciuile: the ritual to reanimate the dead soldier's corpse (6.667–73), and the surgical procedure Erichtho then proceeds to undertake (6.750–7), resembling the practice of a vivisection. The study will focus mostly on the strong connection of magic to medical traditions in antiquity, with a commentary on, and analysis of, these verses through the lenses of medical vocabulary, themes and motifs. It ultimately (...) concludes that Lucan was familiar with the language and characteristics of the medical tradition, enriched his report with them, and was playing with his audience's knowledge of the same.
