RESUMO O objetivo deste artigo é analisar o problema da extensão e do conteúdo da iluminação uma vez que se adote a interpretação regulacionista para a teoria do conhecimento de Agostinho. O regulacionismo, tese defendida por Etienne Gilson, afirma que a iluminação divina do intelecto humano diz respeito ao caráter necessário dos conhecimentos alcançados pela inteligência, e não sobre o conteúdo do conhecimento; assim, a iluminação não teria por função auxiliar na formação de conceitos, mas teria a função de julgar (...) a adequação desses conceitos à verdade. Entretanto, interpretações desse tipo trazem um problema quanto à autonomia cognitiva humana, já que o intelecto seria constrangido externamente em relação ao seu conhecimento. Trataremos, ainda, da crítica sobre a exagerada ênfase na epistemologia que a hipótese regulacionista reverbera. Por fim, e de acordo com o regulacionismo, buscaremos dar uma resposta coerente ao problema da extensão do conhecimento oriundo da iluminação, respeitando tanto a singularidade do raciocínio humano quanto a primazia do conhecimento divino. ABSTRACT The aim of this article is to analyze the issue of the extension and the content of the illumination once the regulationist interpretation for the theory of knowledge of Augustine is adopted. Regulationism, a thesis advocated by Etienne Gilson, states that the divine illumination of the human intellect concerns the necessary character of the knowledge attained by intelligence, not the content of knowledge; Thus, illumination would not have it as an auxiliary function in the formation of concepts, but would have the function of judging the adequacy of these concepts to the truth. However, interpretations of this kind bring with it a problem regarding human cognitive autonomy, given the intellect would be constrained externally in relation to its knowledge. We will also deal with the criticism about the exaggerated emphasis on epistemology in which the regulationist hypothesis reverberates. Finally, and according to regulationism, we will seek to give a coherent answer to the issue of the extension of knowledge from illumination, respecting both the uniqueness of human reasoning and the primacy of divine knowledge.

Durante aproximadamente vinte séculos o que se entendia predominantemente como ciência era a ontologia clássica, entretanto, a partir da modernidade ela começou a perder o status de cientificidade e foi a filosofia crítica de Kant que de forma radical apontou para a sua impossibilidade enquanto ciência. Hegel, porém, acha que a ciência só é verdadeiramente efetiva enquanto ontologia, de modo que ele toma como tarefa de sua filosofia o resgate da ontologia enquanto ciência. Neste horizonte, Hegel através da ontologização da (...) lógica se propõe a resgatar a ontologia enquanto ciência, porém esta é uma nova concepção de ontologia e se apresenta como crítica em relação à ontologia clássica e a crítica kantiana à ontologia clássica.

In his thesis Para uma Teoria Geral dos Homomorfismos (1944), the Portuguese mathematician José Sebastião e Silva constructed an abstract or generalized Galois theory, that is intimately linked to F. Klein’s Erlangen Program and that foreshadows some notions and results of today’s model theory; an analogous theory was independently worked out by M. Krasner in 1938. In this paper, we present a version of the theory making use of tools which were not at Silva’s disposal. At the same time, we (...) tried to keep in mind, so much as possible, the gist of his standpoint. (shrink)

The phenomenon of belief in demonic possessions always appears in times of crisis. The intention of this communication is to report the vision of Michel de Certeau, among others, on a fact of possession that occurred in Loudun and shows that religious motives, for some time in history, have been and are still being used for political manipulation. With great documentary and literary analysis, allied to intense research on the city's folklore and imagery, Certeau shows a perspective on the history (...) of religions in the least different. In the construction of his reasoning and his research, contradictory histories emerge, each at different times and places and each one connected in political and epistemological transformations, of Certeau not only maintains an unconventional authorial posture, but more importantly: it shows the reader That which is lost, missing and fragmented in the process of writing official history.

Com a análise conceitual da arte e da expressão artística, este artigo situa a discussão do ensino de arte em síntese aos pressupostos críticos de Walter Benjamin. Busca-se, primeiramente, o sentido da arte no contexto de seu surgimento, sua valorização cultural e sua função social, para, posteriormente, mediante pressupostos da Teoria Crítica da Sociedade, verificar-se as contradições com sua desintegração na atualidade, apropriada pela indústria cultural como valor de mercadoria. Nesse trajeto, a reprodução técnica da obra de arte tornase o (...) fundamento categórico para a crítica e o desnudamento das formas decadentes sob as quais a arte é “visualizada” na modernidade. A redução das formas estéticas de percepção da arte expressa-se no desaparecimento da experiência, na incapacidade de narrar, na crise da transmissão, enfim, no ensino de arte. (shrink)

Fertility levels have dropped substantially in Latin America in recent decades, fuelled by increased contraceptive use and notably a method mix skewed towards female sterilization. This study examined choice of female sterilization in four Latin American countries: Brazil, Colombia, the Dominican Republic and Peru. Data were drawn from national Demographic and Health Surveys conducted in 1995s reproductive histories to consider the effects of a number of sociodemographic and contextual determinants as they pertained to status at the moment of the event.

AimTo evaluate the cognitive functioning of subjects practicing trance mediumship in Brazil.MethodThe study was based on the measurement of cognitive functions of 19 spirits mediums through neuropsychological tests such as the Brief Cognitive Screening Battery, the Verbal Fluency Test, the digit span test, the cube test, the five digit test and an evaluation of mental health through scales such as the Beck Depression Inventory, the Self-Report Questionnaire, and the Trauma History Questionnaire. The sample included the participation of spirit mediums divided (...) into two groups. The more experienced group with 11 subjects had more than 10 years of mediumistic practice, while the other less experienced group with 8 subjects had 1–5 years of experience. The inclusion criteria were psychophonic mediums with regular trance practices for at least one year. The data collected were analyzed using the SPSS statistical package.ResultsRegarding performance on the BCSB and digit span test, all subjects reached scores at the median or higher in comparison to standardized scores of Brazilians. Scores of 90% on the cube test and 42% on the FAS were reached in comparison to median or higher values, versus the median of standardized scores among Brazilians. On the FDT, we found statistical significance in the choice stage, with higher performance of subjects whose initial age of trance recognition occurred before 21 years old. On the BDI scale, no participant met the criteria for major depression. The SRQ showed an incidence of common mental disorders in 21% of the sample, which was more prevalent in the LEG.ConclusionThe cognitive functioning of subjects who practice trance mediumship in Brazil is associated with cognitive health. Executive dysfunction may be a tendency in LEG. However, an incidence of common mental disorders in the LEG was observed. Executive processing was higher in the subgroup with early practices of recognizing the phenomenon. (shrink)

Este estudo propõe caracterizar Simá: romance histórico do Alto Amazonas, de Lourenço da Silva Araújo e Amazonas, como um “romance épico”, entendido como uma variante de romance histórico distinta da escola hegemônica representada por José Alencar. Esse romance, cujos modelos literários são a Ilíada e a Eneida, elege o rapto da mameluca Simá, chamada de “Helena do Rio Negro”, como a causa imediata da Rebelião de Lamalonga. O romance narra, no plano histórico, o massacre da nação indígena dos Manau pela (...) armada portuguesa e, no plano individual, o destino trágico da protagonista, apresentada como uma vítima inocente do conflito entre Portugal e Espanha. Publicado no mesmo ano de O Guarani, Simá oferece não uma narrativa mítica, como esse célebre romance, mas uma narrativa épica sobre a colonização europeia da Amazônia brasileira. (shrink)

O artigo pretende discutir a possiblidade da percepção interna, delimitando-a do compreender da pessoa, que pode ser tanto compreensão do próximo como autocompreensão. Do mesmo modo, a percepção interna poder ser a percepção de si mesmo como percepção do outro. Parte-se, portanto, de uma indicação recorrente na fenomenologia de Scheler, de acordo com a qual a percepção interna não pode ser reduzida à autopercepção, entendida, sobretudo, no sentido de autoconsciência. Nesta direção, primeiramente, tenta-se uma definição fenomenológica do ato em questão, (...) visando, sobretudo, libertá-lo das determinações idealistas enquanto autoconsciência e das compreensões subjetivistas, tais como a auto-observação e meio de autoconhecimento. Para tanto, demonstra-se que a percepção interna é uma direção de um único ato perceptivo e que o seu objeto não é uma forma lógica pura e vazia, mas sim a apreensão do eu material, concreto e singular. A intuição imediata e direta deste eu, então, aparecerá como a base sobre a qual se rompe com as duas interpretações supracitadas. Por fim, discute-se os elementos internos que contribuem para estes limites, em especial a fisiologia do sentido interno e os interesses do corpo-próprio, o que permite entender positivamente os limites e descrever os seus primeiros significados. A partir deste ganho fenomenológico, a investigação detém-se nos fatores externos, responsáveis por transformar a percepção interna em mero instrumento do autoconhecimento e por subjugá-la às metas e interpretações da cosmovisão natural, analisando brevemente as fontes da idolatria do autoconhecimento. Conclui-se que, na delimitação de sua possibilidade essencial, a desconsideração do papel psicofisiológico do sentido interno, a transladação das leis e relações espaço-temporais próprias da esfera física para a psíquica e, consequentemente, a superposição da percepção externa sobre a interna em consonância com a interpretação sensualista da última são as principais fontes da ilusão denominada idolatria do autoconhecimento.

BackgroundStudies and meta-analyses found individual, meso and micro-social factors that are associated with individual well-being, as well as a positive socio-emotional climate or collective well-being.AimThis article simultaneously studies and examines these factors of well-being.MethodWell-Being is measured as a dependent variable at the individual and collective level, as well as the predictors, in three cross-sectional and one longitudinal studies. Education and social intervention workers from Chile, Spain and Uruguay participate; a subsample of educators from the south central Chile and from Chile, (...) Uruguay and Spain ; workers from organizations in Latin America and Southern Europe, military cadets from Argentina ; and teams from Spanish companies.ResultsIndividual and collective well-being indicators were related, suggesting that the emotional climate as a context improves personal well-being. Individual factors, psychosocial factors were positively associated with personal well-being in education and social intervention context. Organizational dynamic or transformational culture is directly and indirectly associated with individual well-being through previously described psychosocial factors. Group processes such as internal communication and safe participation, task orientation or climate of excellence as well as leadership style that reinforces participation and belonging, were positively associated with collective well-being in labor and military context and predict team work socio-emotional climate in a longitudinal study- but were unrelated to individual well-being. Transformational leadership plays a mediating role between functional factors and social-emotional climate in work teams. Organizational role autonomy, functional organizational leadership, integration and resources were associated with collective well-being in organizations. Organizational leadership moderates the relationship between task orientation and collective well-being in military context.ConclusionIndividual and microsocial factors influence personal well-being. Meso level factors favorable to well-being through processes which reinforce social belonging, influence directly collective well-being and indirectly personal well-being. Leadership that reinforces participation and belonging play a central role for emotional climate. Stress and emotional climate playing an important pivotal role for psychological well-being.

A idéia deste artigo é tentar demonstrar, através da construção da personagem Capitu feita por Bentinho, como o romance Dom Casmurro, em alguma medida, se apropria do mito de Helena, principalmente da versão relatada por Eurípides em tragédia homônima. As duas personagens não têm em comum somente o fato de serem consideradas adúlteras — sem que isso possa ser comprovado nas respectivas narrativas —, mas um todo ficcional que nos leva a essa relação.

The study consists of a phenomenological reflection on the essence of man based on the meaning of his discourse in the era of technique. Considering the history of metaphysics at its end, in which all saying and thinking are commanded by information technologies, one wonders about the situation of language, understood as the pronouncement of human existence. Based on Heidegger's phenomenology and, particularly, on the notion of discourse as a fundamental structure made explicit by Sein und Zeit's existential ontology, it (...) is demonstrated that the focus of the discussion is not simply to question the instrumental use and technological application of language. Rather, the key for elaborating the interrelationship between discourse and technique is to capture the sense by which the contemporary man discourses his existence-in-the-world, transitioning from an original way of saying and understanding himself to one in which he and his world are governed by a challenging and provocative power of realness in his reality. It is shown that, to guarantee this contemporary man’s position with the entities, it is necessary for the technique to be a meaning to pronounce its existence, providing the meaning of being-device for the existence and its own possibilities, as well as for the mundane things. At the same time, it is clarified that, since the realization of human existence is guided by this meaning and challenging power represented by the technique, the instrumentalization of languages and their reduction to a communication system managed by information technologies, among other consequences, are required.

Departing from theories of distributive justice and their relation with the distribution of health care within society, especially egalitarianism and libertarianism, this paper aims at demonstrating that the approach taken by the European Court of Justice regarding the application of the Internal Market principles to the field of health care services has introduced new values which are more concerned with a libertarian view of health care. Moreover, the paper also addresses the question of how these new values introduced by the (...) Court may affect common principles of European health systems, such as equity and accessibility.

The COVID-19 pandemic produced immeasurable impacts on the economy, education, and socialization, besides the loss of millions of lives. Thus, there has been an accelerated development of an unprecedented number of COVID-19 vaccine candidates to control the pandemic. The World Health Organization’s emergency use authorization of COVID-19 vaccines still in clinical trial allowed immunizing the population. This paper presents a perspective of the bioethical precepts of autonomy, non-maleficence, beneficence, and justice in the emergency use of COVID-19 vaccines. Furthermore, it emphasizes (...) the importance of surveillance at all stages of vaccine development to detect adverse effects and ensure compliance with bioethical precepts. (shrink)

O artigo é uma discussão fenomenológica acerca da natureza. Fundamentada no pensamento tardio de Heidegger, ela se desenvolve em torno da superação da determinação metafísica da realidade natural enquanto presença constante. Para tanto, toma-se como guia da reflexão um verso das poesias tardias de Hölderlin, cujo aclaramento conduz ao questionamento do sentido da noção de presença e da sua referência com a ausência e, em seguida, da relação essencial entre ser e aparência. Nesta direção, mostra-se que a sublime aparição da (...) natureza é a luta e unidade entre parusia e apousia. (shrink)

The work exposed hereafter intends to examine the ambiguous character of identities according to the analyses of the French philosopher Étienne Balibar. The text will focus on his works from the late eighties, where there is a distancing from the circle formed around Althusser and an approach to the philosophies of difference of Foucault, Deleuze and Derrida. We will seek to explain how the author, through the prism of Marxist class conflicts, will denounce the echelonment process of individuals in a (...) hierarchical fashion within the capitalist world-economy based on multiple identity processes which respect the logic of maintaining the existing international social structure. The background of such analyses is the rise of xenophobic and neo-fascists movements which have not ceased to increase in today's Europe as a reaction to a profound crisis of the nation-state, its institutions and the fragmentation of ideally established communities.

In 1999, da Silva, D'Ottaviano and Sette proposed a general definition for the term translation between logics and presented an initial segment of its theory. Logics are characterized, in the most general sense, as sets with consequence relations and translations between logics as consequence-relation preserving maps. In a previous paper the authors introduced the concept of conservative translation between logics and studied some general properties of the co-complete category constituted by logics and conservative translations between them. In this paper we (...) present some conservative translations involving classical logic, Lukasiewicz three-valued system L 3, the intuitionistic system I 1 and several paraconsistent logics, as for instance Sette's system P 1, the D'Ottaviano and da Costa system J 3 and da Costa's systems C n, 1 n.

SummaryPrevious research has indicated that biological older brothers increase the odds of androphilia in males. This finding has been termed thefraternal birth order effect. Thematernal immune hypothesissuggests that this effect reflects the progressive immunization of some mothers to male-specific antigens involved in fetal male brain masculinization. Exposure to these antigens, as a result of carrying earlier-born sons, is hypothesized to produce maternal immune responses towards later-born sons, thus leading to female-typical neural development of brain regions underlying sexual orientation. Because this (...) hypothesis posits mechanisms that have the potential to be active in any situation where a mother gestates repeated male fetuses, a key prediction is that the fraternal birth order effect should be observable in diverse populations. The present study assessed the association between sexual orientation and birth order in androphilic male-to-female transsexuals in Brazil, a previously unexamined population. Male-to-female transsexuals who reported attraction to males were recruited from a specialty gender identity service in southern Brazil and a comparison group of gynephilic non-transsexual men was recruited at the same hospital. Logistic regression showed that the transsexual group had significantly more older brothers and other siblings. These effects were independent of one another and consistent with previous studies of birth order and male sexual orientation. The presence of the fraternal birth order effect in the present sample provides further evidence of the ubiquity of this effect and, therefore, lends support to the maternal immune hypothesis as an explanation of androphilic sexual orientation in some male-to-female transsexuals.

Objective: This study aims to compare the acoustic vocal analysis results of a group of transgender women relative to those of cisgender women.Methods: Thirty transgender women between the ages of 19 and 52 years old participated in the study. The control group was composed of 31 cisgender women between the ages of 20 and 48 years old. A standardized questionnaire was administered to collect general patient data to better characterize the participants. The vowel /a/ sounds of all participants were collected (...) and analyzed by the Multi-Dimensional Voice Program advanced system.Results: Statistically significant differences between cisgender and transgender women were found on 14 measures: fundamental frequency, maximum fundamental frequency, minimum fundamental frequency, standard deviation of fundamental frequency, absolute jitter, percentage or relative jitter, fundamental frequency relative average perturbation, fundamental frequency perturbation quotient, smoothed fundamental frequency perturbation quotient, fundamental frequency variation, absolute shimmer, relative shimmer, voice turbulence index, and soft phonation index. The mean fundamental frequency value was 159.046 Hz for the cases and 192.435 Hz for the controls.Conclusion: Through glottal adaptations, the group of transgender women managed to feminize their voices, presenting voices that were less aperiodic and softer than those of cisgender women.

This article analyses the role of sacred and religious art in Amazonia in the context of the catholic renovation movement of the 19th century, known as Catholic Reform. For that, it takes the order of the main altar of Our Lady of Belém by Pará’s Bishop Antônio de Macedo Costa to Italian architect Luca Carimini as its study object. This piece, along with others made throughout the period of Pio IX’s pontificate, constitutes an iconological programme as well as an (...) artistic and sacred narrative body, which testify to the pedagogical and political debates on the history of Roman Catholicism in Brazil in the 19th century. Besides that, it moves artists that acted under the patronage of Pope Pius IX in Latin American cities such as Santiago, in Chile, and Belém do Pará, in Brazil, putting in evidence the artistic, intellectual and religious connections between the Vatican and South America, as part of an international renewal movement of Catholicism.

Discuto nele as noções de introspecção, linguagem privada, vida interior, linguagem referencial, sentido, ação intencional, sintomas, critérios, razões causais e objetivos da clínica psicanalítica, todas questionadas pelo autor do artigo. Sugere-se que as críticas feitas às idéias de Márcia Cavell e de Jurandir Freire Costa sobre esses tópicos devem-se a mal-entendidos teóricos e não à incompatibilidade conceitual (...) entre o vocabulário psicanalítico e as teses do neopragmatismo lingüístico.This article is an answer back to João José Rodrigues Lima de Almeida's article "The pragmatic psychoanalysis and the paradox of interpretation".

It is suggested that the criticisms on Marcia Cavell's and Jurandir Freire Costa's readings on those conceptions are due to theoretical misunderstandings rather than conceptual incompatibility between the psychoanalytic vocabulary and the linguistic neopragmatism.

Este artigo pretende abordar, por um viés filosófico, o problema dos Direitos Humanos enunciados em Declarações dos séculos XVIII e XX. A questão de fundo consiste nos Direitos do Homem a partir do “ideal de humanidade” ou “dignidade humana” considerando duas ideias: 1) o paradoxo da Declaração dos Direitos do Homem e do Cidadão e a noção de que só se sente um “humano” com direitos garantidos alguém que se vê contemplado no bojo jurídico de uma nação. 2) A humanidade (...) como “grande família”, e o mundo como “grande nação”. Para tanto, promovemos neste trabalho um debate entre três pensadores: Diderot, com sua noção de vontade geral do gênero humano; Rousseau, com sua refutação à tese de Diderot, negando que exista uma “sociedade natural ou geral entre os homens”; e Kant, que no seu À Paz Perpétua retoma, a seu modo, a noção de cosmopolitismo negada por Rousseau e aponta para a possibilidade do direito se estender a toda a humanidade.

This paper intends to introduce the three issues of Principia which will appear in a sequel honoring Newton da Costa’s 80th birthday. Instead of presenting the papers one by one, as it is common in presentations such as this one, we have left the papers speak by themselves, and instead we have preferred to present to the Brazilian readers, specialty to our students, some aspects of Newton da Costa’s conception of science and of the scientific activity, grounded on (...) the concept of quasi-truth, which he contributed to develop in a rigorous way. Da Costa is known as one of the founding fathers of paraconsistent logic, but his contributions go also to the foundations of physics, theoretical computation, model theory, algebraic logic, lattice theory, applications of non-classical logics to law and technology, etc. But perhaps his main contribution was to provide a basis for the birth of a school of logic in our country, serving as teacher and inspiring new researchers for generations. It is a pleasure to have had so enthusiastic acceptation from the editors of Principia to organize these volumes. I would like to thank the contributors and the editors of Principia, specially Prof. Cezar Mortari for his help in organizing the issue. (shrink)

In the past thirty years, two fundamental issues have emerged in the philosophy of science. One concerns the appropriate attitude we should take towards scientific theories--whether we should regard them as true or merely empirically adequate, for example. The other concerns the nature of scientific theories and models and how these might best be represented. In this ambitious book, da Costa and French bring these two issues together by arguing that theories and models should be regarded as partially rather (...) than wholly true. They adopt a framework that sheds new light on issues to do with belief, theory acceptance, and the realism-antirealism debate. The new machinery of "partial structures" that they develop offers a new perspective from which to view the nature of scientific models and their heuristic development. Their conclusions will be of wide interest to philosophers and historians of science. (shrink)

“Tell me," Wittgenstein once asked a friend, "why do people always say, it was natural for man to assume that the sun went round the earth rather than that the earth was rotating?" His friend replied, "Well, obviously because it just looks as though the Sun is going round the Earth." Wittgenstein replied, "Well, what would it have looked like if it had looked as though the Earth was rotating?” What would it have looked like if we looked at all (...) sciences from the viewpoint of Wittgenstein’s philosophy? Wittgenstein is undoubtedly one of the most influential philosophers of the twentieth century. His complex body of work has been analysed by numerous scholars, from mathematicians and physicists, to philosophers, linguists, and beyond. This volume brings together some of his central perspectives as applied to the modern sciences and studies the influence they may have on the thought processes underlying science and on the world view it engenders. The contributions stem from leading scholars in philosophy, mathematics, physics, economics, psychology and human sciences; all of them have written in an accessible style that demands little specialist knowledge, whilst clearly portraying and discussing the deep issues at hand.

Existem muitas teorias sobre democracia. Na verdade, enquanto se fala de “teoria democrática” como se existisse um consenso acerca do que esta poderia significar, a partir do momento em que nos debruçamos sobre diferentes autores, apercebemo-nos de que há tantas teorias quanto há perspectivas sobre o tema. Neste artigo tenho como interlocutores Robert Dahl, Benjamin Barber, Robert Goodin e David Plotke. O artigo tem três momentos. No primeiro, desenho o contexto geral para uma reflexão crítica sobre democracia, partindo da análise (...) dos seus conceitos constitutivos, nomeadamente, os conceitos de representação, participação e deliberação. Este é o momento “estrutural”. De seguida, apoiando-me nos critérios ou virtudes de Dahl e no conceito de “democracia forte” de Barber, defendo que a instanciação dos vários modelos democráticos depende da importância que se confere a cada um dos critérios. Este é o momento de conteúdo. Dialogando com estes autores procuro identificar as implicações dos modelos representativo, participativo e deliberativo. Por último, procuro uma forma de redefinição da democracia mais positiva para o futuro, tendo o orçamento participativo como prática exemplar a seguir. (shrink)

We investigate the higher-order modal logic , which is a variant of the system presented in our previous work. A semantics for that system, founded on the theory of quasi sets, is outlined. We show how such a semantics, motivated by the very intuitive base of Schrödinger logics, provides an alternative way to formalize some intensional concepts and features which have been used in recent discussions on the logical foundations of quantum mechanics; for example, that some terms like 'electron' have (...) no precise reference and that 'identical' particles cannot be named unambiguously. In the last section, we sketch a classical semantics for quasi set theory. (shrink)
