Fernando Gil estabeleceu uma seminal relação filosófica entre a evidência e a alucinação. Como acentua no Tratado da Evidência, “sem por isso ser, a alucinação não é uma representação, o seu conteúdo é uma coisa-em-si”. As representações da alucinação como evidência e da evidência como alucinação tendem a manifestar-se, em termos literários, no que habitualmente se caracteriza como o fantástico. M. Teixeira-Gomes representou os processos literários da evidência alucinatória em termos que parecem mais próximos do pensamento filosófico de Fernando (...) Gil do que da literatura fantástica propriamente dita, situando no mesmo plano de significação o factual, o mítico e o alucinatório como manifestações complementares daquilo que caracterizou como o seu “teatro da alma”.

Phenomenal particularism is the view that particular external objects are sometimes part of the phenomenal character of perceptual experience. It is a central part of naïve realist or relational views of perception. We consider a series of recent objections to phenomenal particularism and argue that naïve realism has the resources to block them. In particular, we show that these objections rest on assumptions about the nature of phenomenal character that the naïve realist will reject, and that they ignore the full (...) resources that naïve realism has to offer in explaining phenomenal character.

Why is gauge symmetry so important in modern physics, given that one must eliminate it when interpreting what the theory represents? In this paper we discuss the sense in which gauge symmetry can be fruitfully applied to constrain the space of possible dynamical models in such a way that forces and charges are appropriately coupled. We review the most well-known application of this kind, known as the 'gauge argument' or 'gauge principle', discuss its difficulties, and then reconstruct the gauge argument (...) as a valid theorem in quantum theory. We then present what we take to be a better and more general gauge argument, based on Noether's second theorem in classical Lagrangian field theory, and argue that this provides a more appropriate framework for understanding how gauge symmetry helps to constrain the dynamics of physical theories.

Here we discuss a “chromosome separation checkpoint” that might regulate the anaphase‐telophase transition. The concept of cell cycle checkpoints was originally proposed to account for extrinsic control mechanisms that ensure the order of cell cycle events. Several checkpoints have been shown to regulate major cell cycle transitions, namely at G1‐S and G2‐M. At the onset of mitosis, the prophase‐prometaphase transition is controlled by several potential checkpoints, including the antephase checkpoint, while the spindle assembly checkpoint guards the metaphase‐anaphase transition. Our hypothesis (...) is based on the recently uncovered feedback control mechanism that delays chromosome decondensation and nuclear envelope reassembly until effective separation of sister chromatids during anaphase is achieved. A central player in this potential checkpoint is the establishment of a constitutive, midzone‐based Aurora B phosphorylation gradient that monitors the position of chromosomes along the spindle axis. We propose that this surveillance mechanism represents an additional step towards ensuring mitotic fidelity. (shrink)

The present paper is about the author’s current research on children’s education in urban contexts. It departs from the rising offer of programmes for school children in out-of-school contexts (e.g. museums, libraries, science centres). It asks what makes these practices educational (and not just interesting, entertaining and/or audience building). Based on Biesta ( 2006a , 2010 ) theory of education, the author frames and analyses the educational characteristics of, and possibilities of articulating, in and out-of-school educational practices. This paper aims (...) at understanding if the occasional outing from primary school premises promotes interruptions in the humanist foundations of school. In order to analyse relations between different institutions and professionals (to be) engaged in educational activities and programmes, Nóvoa ( 2002 , 2009 ) essays will be brought to the discussion, namely his conception of the ‘Public Space of Education’—as a space where culture, education, arts, sports and leisure are shared responsibilities, and where diverse institutions are networked aiming towards societal pluralism. I argue for the possibility of using cities’ public spaces as contexts with a worldly quality to complexify children’s education. Nevertheless, I draw attention to the unbearable educational lightness that these practices may carry if they do not go beyond the praise of chance; as well as to their unsustainable weight if they perpetually repeat school’s normal orders and add up rational discourses.

Pretende-se nesse artigo articular as noções de ética e política às noções do Dizer e do Dito, em uma perspectiva muito sutil apresentada por Emmanuel Levinas, para demonstrar como o sentido do humano se inicia na ética e necessariamente se dirige à política, uma vez que, para esse autor, a filosofia tem que ir ao fato social. Essa articulação se torna possível pela noção de justiça presente em dois momentos do humano: o momento inicial do frente a frente do Eu (...) e do Outro ou ética e o momento em que a pluralidade se torna real pela presença do Terceiro, ou política. A preocupação levinasiana é, não só a de afirmar a primazia da ética em relação à política, no que diz respeito à ordem do acontecimento, mas também de demonstrar que a presença do Dizer original do frente a frente que se inscreve como exigência de justificativas para um Eu absoluto, deve permanecer na relação política, quando em sua impostação institucional a partir da Lei e do Estado pretenderem absolutizar-se em relação as demandantes da própria justiça. Assim, o Dito da Lei está sob os auspícios de um novo Dizer que pode destituir a razoabilidade daquele, exatamente pela presença de Terceiros, diferentes e não incluídos na ordem jurídica. A ordem politico-jurídica que em sua demora tem feições ontológicas, quando não se abre para o Dizer perene, pode tornar-se ordem violenta, tal qual a ordem que prepondera no fenômeno da guerra. O sentido do humano, segundo Levinas está na démarche da relação dual do frente a frente à multiplicidade das relações políticas alicerçadas na noção de justiça como exigência de justificação para a ação.

Education aims at the integral development of the person. However, there are few proposals that conceptualize ways to implement this desideratum. In the Portuguese context, we had the paradigmatic case of the Manuel Ferreira Patrício Cultural School. MFP differentiates itself by advocating for integral education that establishes an essential connection between the teaching, extra-lecture, interactive and ecological components of the school, highlighting the multidimensionalities of education: personality, culture, methodologies, curriculum, resources, educators, and pedagogical organization.

Selon Damásio, le moi conscient se crée à partir de la capacité du cerveau à raconter, c’est-à-dire à transformer en récit les signaux et messages produits par ses diverses couches. Les mythes donnent au monde une cohérence significative qui provient de l’organisation des éléments que ses récits produisent. Les rapports au monde de toutes les espèces vivantes sont contenus dans les limites de leurs possibilités phylogénétiques qui résultent déjà d’une relation continuée pendant des millions d’années. La capacité humaine de créer (...) des récits sur le réel doit intégrer ces éléments phylogénétiques qui se manifestent même dans les parties non conscientes du cerveau intégrées pourtant dans le récit qui construit un moi. Ce dépôt venu du fond des âges est une des causes de l’excès de sens que nous poursuivons toujours et qui est, au niveau de l’imaginaire « premier » la voix de ce fonds dans ces rapports avec le texte du monde. Un récit est ainsi une façon de donner à voir l’invisible, et cette invisibilité produit un excès de sens qui cherche toujours à se manifester. Il est marqué par les cohérences et consistances des images de cet imaginaire premier qui médiatise toujours nos relations au monde et aux autres, et auquel s’ajoute les cohérences des imaginaires « seconds » des individus et des cultures. According to Damásio, the self-conscious arises from the ability of the brain to tell, i.e. turn into a story the signals and messages produced by its various layers. Myths give the world a significant consistency that comes from the organization of the elements produced by its stories. The relationships of all living species with the world are contained within the limits of their phylogenetic opportunities resulting from a relationship continued for millions of years. The human ability to create stories about reality must incorporate these phylogenetic elements into the narrative that builds self-awareness. This unknown repository coming from the depths of time is one of the causes of the excess of meaning that we always pursue and is, at the level of the basic imaginary, one that Gilbert Durand considered the heritage of sapiens, the voice of these assets in their links with the text of the world. A narrative is thus a means of seeing the invisible, and this invisibility produces an excess of meaning which always seeks to manifest itself. It is marked by the coherence and consistency of the images of this basic imaginary which always mediates our relationship to the world and to others, and to which is added the coherences of the secondary imaginary coming from individuals and cultures.

To respond to globalization‐related challenges, many contemporary political theorists have argued for forms of democracy beyond the level of the nation‐state. Since the early 1990s, however, political theory has also witnessed a renewed normative defense of nationhood. Liberal nationalists have been influential in claiming that the state should protect and promote national identities, and that it is desirable that the boundaries of national and political units coincide. At first glance, both positions—global democracy and nationalism—seem to contradict each other. We do (...) not share this oppositional picture. Developing a more harmonic picture of nationalist ideals and cosmopolitan visions is the aim of this essay. (shrink)

By Portuguese myths we mean several kinds of narratives, all of which actualize fundamental aspects of the Portuguese national imagination. Some are foundation narratives (Sâo Mamede, Ourique); others are historical facts that were sung so often over the years by Portuguese and foreign poets that they came to signify basic schemes of the human imagination (Inês de Castro's pure love, whose realization was frustrated by a fight between two men, father and son); other so-called Portuguese myths, on the contrary, are (...) built around concepts that give metaphysical shape to supposed characteristics that define the national soul (saudosismo, the doctrine of nostalgia, which attempts to define the Portuguese national soul as the search for a mythical initial unity that would create a wholeness in which contraries would be abolished; the Fifth Empire as its realization on Earth); other Portuguese myths express the supposed divine predestination of the people and of the Portuguese Man, based upon divine intervention in the founding of the nation in Ourique (the Fifth Empire that would be the Age of Spirit announced by Joachim de Fiore); still others are based on historically negative facts (King Sebastian and the defeat at Alcazarquibir) but transformed through archetypal elements to show the capacity for renewal out of the defeat, a renewal that goes beyond real historical renewal to include spiritual renewal of the Portuguese Man and his fatherland, which should produce the Fifth Empire conceived either in earthly or spiritual terms. To these myths I will add a legend preceding the formation of the nation, King Roderick's Legend, because it attempts to justify the loss of Visigothic Spain to the Arabs. (shrink)

Organisations are increasingly transforming themselves to remain profitable and obtain sustainable competitive advantages. Business processes are as important as technology in promoting organisational transformation. Organisational transformation ultimately entails combining existing business components, whether or not with the same use and design, with new ones to generate novel products and services. For example, one particular type of organisation transformation is digital transformation. This notion, which covers even the subjective aspects of organisational transformation, is currently under intensive discussion and suffers from the (...) semantics terms fluctuation related to the notion of ‘organisational transformation’. We argue that this topic could strongly benefit from an ontological analysis and conceptual clarification of these notions. This paper contributes with an attempt in this direction by proposing a Core Ontology of Organisational Transformation (COOT). This ontology comprises concepts and relations central to creating a reference model representing the organisational transformation paradigm. COOT was applied in a real-world case study on a car rental company. (shrink)

Resumo Palavras-chave Keywords : Narrative production. Authorship. Language. Memory. Identity. : This article comprises a detailed report on a project of narrative production, which is being conducted, every semester, with students entering the Languages course, on the Portuguese Language subject.The project consists of a process of production, reading, and rewriting of small narratives, which, at the end of the term, are gathered and organized by each student in order to assemble their own book craftily. The proposal came forth as a (...) strategy to try to solve problems related to the little familiarity with writing and to the lack of authorship marks. The engagement in the production of contextualized and guided narratives for a determined purpose has disclosed, at the end of each semester, similar results: pleasure to write, read and expose the produced texts for group discussions; concern with the interlocutor; presence of authorship marks; perception of discursive qualities on the text itself and on the text of others; concern with the adequacy of the writing to linguistic conventions; confidence on the writing process; perception of oneself as part of a history and as a result of multiple intersubjectivities; praise of one’s own life history and of one’s ancestors. The project finds itself based on enunciation theories. : Produção de narrativa. Autoria. Linguagem. Memória. Identidade. : Este artigo constitui-se do relato de um projeto de produção de narrativa que vem sendo desenvolvido, semestralmente, com alunos ingressantes no curso de Letras, na disciplina de Língua Portuguesa. O projeto consiste em um processo de produção, leitura e reescritura de pequenas narrativas com as quais, ao fim do semestre, cada aluno organiza e confecciona artesanalmente o seu próprio livro. A proposta surgiu como estratégia para tentar solucionar problemas relacionados à pouca familiaridade com a escrita e à ausência de marcas de autoria. O enfoque na produção de narrativas contextualizadas e orientadas para um determinado fim tem revelado, no fim de cada semestre, resultados semelhantes: prazer de escrever, de ler e de submeter à discussão do grupo os textos produzidos; preocupação com o interlocutor; presença de marcas de autoria; percepção de qualidades discursivas no próprio texto e no texto do outro; preocupação com a adequação da escrita às convenções linguísticas; segurança em relação à escrita; percepção de si como parte de uma história e como fruto de intersubjetividades múltiplas; valorização da própria história de vida e da de seus antepassados.

Seven informants , aged between 32 and 42, who had experienced at least one career change in their lives were interviewed about the history of their career trajectories. The interviews were analyzed according to the systematic and systemic reflexivity proposed by the phenomenological tradition: description, reduction and interpretation. The findings point to the need for professional guidance practice giving attention not only to professional information but also to a reflection of individual and work-related values. This would help both young people (...) and adults to see their own objectives more clearly and to be capable of formulating their own career plans and following them through. (shrink)

This article studies an aspect of the relation between emotions and ethics that is usually neglected in the recent debate on moral emotions. By focusing on the contributions of common or everyday emotions to the development of moral behaviours and attitudes, the debate loses sight of the emotional side of the ethical attitude and the way it involves different, specifically ethical emotions. In contrast, such emotions play an important role in Aristotle’s and Heidegger’s thought. As will be shown, both authors (...) identify emotions that are intrinsically tied to ethics in a broad sense and are structurally different from everyday emotions. Moreover, both characterize the two kinds of emotion in a similar fashion: whereas everyday emotions involve a limited form of activity and refer to a more immediate objective domain, the properly ethical emotions result from a superior form of activity and open up to a vaster domain or even to the entire reality, thus having a metaphysical character. The study of this distinction and what it involves will allow for a better understanding not only of emotions in general, but also of the emotional dimension of ethical life. (shrink)

The historical formation of Brazil is distinguished from the majority of ex-colonial nations by one factor that is especially characteristic: an intense process of ethnic and cultural mixing. The Portuguese colonisers, who, unlike the English Puritans in North America, left their families and arrived in Brazil in small groups mainly composed of men, naturally tended to pair off with the women they found available - first of all indigenous women and later African women. There was nothing in Brazil to prevent (...) this spontaneous behaviour similar to the role played in the English colonies of North America by the strength of the family group or the strict religious observance of the community. Thus from the outset Brazil tended to accept racial mixing as a de facto reality. As Gilberto Freyre correctly noted in his book Casa Grande e Senzala:They mixed happily with women of colour from the very first contacts and many mixed-race children resulted, so much so that only a few thousand men were enough to colonize vast areas and compete with the greatest and most numerous peoples as regards the extent of the colonial territory and the effectiveness of colonizing activity.

Since the last war, one character of the political system in Belgium is the growth and the duration of the ministerial crisis. Some questions of public law appeared. How is it possible to maintain the continuity of the political and administrative action, without ministerial responsibility to Parliament, during the crisis?

Cet article propose un itinéraire de réflexion sur les fondements de l’éthique théologique en articulant trois contributions de Karl Barth à ce domaine : la définition de l’éthique comme l’impératif de l’indicatif qu’est la dogmatique, voire l’inséparabilité entre éthique et dogmatique qui place l’éthique à l’écoute de la révélation ; l’articulation d’un nexus christologique entre les catégories d’obéissance et de liberté comme « autodétermination déterminée » ; le débat sur l’Évangile et la Loi, comme révélation de l’histoire de la grâce (...) à partir de laquelle se déploie la grammaire d’une existence chrétienne. Cet itinéraire est entrecoupé par trois passages bibliques qui sont alignés sur les contributions de Barth : la vocation d’Abraham ; l’agonie de Jésus à Gethsémani ; la question posée à Jésus sur le bien qu’il faut faire pour entrer dans la vie éternelle. Nous suggérons que cet itinéraire biblique et barthien souligne qu’une éthique théologiquement construite conflue vers la christologie. (shrink)

Visual experiences seem to exhibit phenomenological particularity: when you look at some object, it – that particular object – looks some way to you. But experiences exhibit generality too: when you look at a distinct but qualitatively identical object, things seem the same to you as they did in seeing the first object. Naïve realist accounts of visual experience have often been thought to have a problem with each of these observations. It has been claimed that naïve realist views cannot (...) account for the generality of visual experiences, and that the naïve realist explanation of particularity has unacceptable implications for self- knowledge: the knowledge we have of the character of our own experiences. We argue in this paper that neither claim is correct: naïve realism can explain the generality of experiences, and the naïve realist explanation of particularity raises no problems for our self-knowledge.

Neste ensaio apresentamos o conceito de vida para o filósofo e médico francês Georges Canguilhem (1904-1995) e, posteriormente, desenvolvemos uma reflexão deste conceito, estabelecendo um paralelo entre a emergência da tecnociência e o transumanismo. Na primeira parte do ensaio, foram selecionados trechos das obras de Canguilhem, O normal e o patológico, O conhecimento da vida e o verbete “vida” escrito para a Encyclopédie Universalis. Sobre o verbete daremos atenção para a quarta interpretação sobre a vida proposta pelo filósofo. Além dos (...) textos escolhidos, utilizaremos artigos de especialistas que aprofundem a filosofia de Georges Canguilhem. Na segunda parte, apresentaremos, de modo geral, o surgimento e as implicações éticas da tecnociência na sociedade contemporânea. Na terceira parte, apresentaremos uma possível origem do transumanismo e o instigante e complexo debate em torno deste movimento. Neste tópico apresentaremos as contribuições de filósofos alinhados ao pensamento de Canguilhem e filósofos que refletem sobre o movimento transhumanista, tais como João de Fernandes Teixeira, Natasha Vita-More e Nick Bostrom. Na conclusão, apresentaremos a relevância do diálogo entre as áreas do conhecimento como a filosofia, ciências da vida e tecnologia para compreendermos os meandros da sociedade contemporânea.Palavras chave: Georges Canguilhem; vida; tecnociência; transhumanismo.

Nota Bibliográfica: ROUARD, Christophe. La vérité chez Alasdair MacIntyre. Paris: L’Harmattan, 2011. 254p. ISBN 978-2-296-54736-0.

A revista Revue Internationale de Philosophie publicou recentemente um número dedicado à filosofia de Alasdair MacIntyre, incluindo artigo dele respondendo às críticas apresentadas no volume por Vincent Descombes, John Rist, Ronald Beiner e James Bernard Murphy.

O artigo discute a relação entre verdade e moralidade na ética das virtudes de Alasdair MacIntyre, apontando para a tensão entre o realismo metafísico-teológico pressuposto em sua virada tomista a partir de Three Rival Versions of Moral Enquiry, e a matriz, a nosso ver, claramente hermenêutico-pragmática de seu modelo da racionalidade das tradições morais de pesquisa racional, explicitado anteriormente em Depois da Virtude e em Justiça de Quem? Qual Racionalidade?.

O artigo busca explicitar, a partir da perspectiva da ética da responsabilidade de Hans Jonas, em um diálogo com a ética das virtudes, que virtudes morais são necessárias como componentes da afirmação jonasiana de cuidado pela vida e pela manutenção da existência da humanidade, mesmo em um futuro próximo, diante da ameaça trazida pela emergência climática — produzida pela própria humanidade em seu modus operandi de intensivo uso das tecnologias como correia de transmissão do capitalismo global —; bem como pelas (...) questões postas pela emergência da pandemia da Covid-19, especialmente pela lida requerida diante de um problema global que ameaça diretamente a vida diante de nossos olhos no presente e em futuros próximos. A pandemia da Covid-19 é um mote para defender a necessidade urgente do cultivo de certas virtudes que dão cumprimento ao princípio responsabilidade, mas também de obtenção de compreensão prévia concreta das enormes dificuldades envolvidas no enfrentamento ético da emergência climática.

In this work, we propose a computational approach to the triadic model of Peircean semiosis (meaning processes). We investigate theoretical constraints about the feasibility of simulated semiosis. These constraints, which are basic requirements for the simulation of semiosis, refer to the synthesis of irreducible triadic relations (Sign–Object–Interpretant). We examine the internal organization of the triad S–O–I, that is, the relative position of its elements and how they relate to each other. We also suggest a multi-level approach based on self-organization principles. (...) In this context, semiosis is described as an emergent process. Nevertheless, the term ‘emergence’ is often used in a very informal way in the so called ‘emergent’ computation, without clear explanations and/or definitions. In this paper, we discuss in some detail the meaning of the theoretical terms ‘emergence’ and ‘emergent’, showing how such an analysis can lead to improvements of the algorithm proposed. (shrink)

This paper investigates the implicative conditional, a connective intended to describe the logical behavior of an empirically defined class of natural language conditionals, also named implicative conditionals, which excludes concessive and some other conditionals. The implicative conditional strengthens the strict conditional with the possibility of the antecedent and of the contradictory of the consequent. $${p\Rightarrow q}$$ p ⇒ q is thus defined as $${\lnot } \Diamond {(p \wedge \lnot q) \wedge } \Diamond {p \wedge } \Diamond {\lnot q}$$ ¬ ◊ (...) ( p ∧ ¬ q ) ∧ ◊ p ∧ ◊ ¬ q. We explore the logical properties of this conditional in a reflexive normal Kripke semantics, provide an axiomatic system and prove it to be sound and complete for our semantics. The implicative conditional validates transitivity and contraposition, which we take to be integral parts of reasoning and communication. But it only validates restricted versions of strengthening the antecedent, right weakening, simplification, and rational monotonicity. Apparent counterexamples to some of these properties are explained as due to contextual factors. Finally, the implicative conditional avoids the paradoxes of material and strict implication, and validates some connexive principles such as Aristotle’s theses and weak Boethius’ thesis, as well as some highly entrenched principles of conditionals, such as conjunction of consequents, disjunction of antecedents, modus ponens, cautious monotonicity and cut.
