I apply some of the lessons from quantum theory, in particular from Bell’s theorem, to a debate on the foundations of decision theory and causation. By tracing a formal analogy between the basic assumptions of causal decision theory (CDT)—which was developed partly in response to Newcomb’s problem— and those of a local hidden variable theory in the context of quantum mechanics, I show that an agent who acts according to CDT and gives any nonzero credence to some possible causal interpretations (...) underlying quantum phenomena should bet against quantum mechanics in some feasible game scenarios involving entangled systems, no matter what evidence they acquire. As a consequence, either the most accepted version of decision theory is wrong, or it provides a practical distinction, in terms of the prescribed behaviour of rational agents, between some metaphysical hypotheses regarding the causal structure underlying quantum mechanics.

Bellʼs 1964 theorem causes a severe problem for the notion that correlations require explanation, encapsulated in Reichenbachʼs principle of common cause. Despite being a hallmark of scientific thought, dropping the principle has been widely regarded as much less bitter medicine than the perceived alternative—dropping relativistic causality. Recently, however, some authors have proposed that modified forms of Reichenbachʼs principle could be maintained even with relativistic causality. Here we break down Reichenbachʼs principle into two independent assumptions—the principle of common cause proper and (...) factorization of probabilities. We show how Bellʼs theorem can be derived from these two assumptions plus relativistic causality and the law of total probability for actual events, and we review proposals to drop each of these assumptions in light of the theorem. In particular, we show that the non-commutative common causes of Hofer-Szabó and Vecsernyés fail to have an analogue of the notion that the common causes can explain the observed correlations. Moreover, we show that their definition can be satisfied trivially by any quantum product state for any quantum correlations. We also discuss how the conditional states approach of Leifer and Spekkens fares in this regard. (shrink)

In a recent no-go theorem [Bong et al., Nature Physics (2020)], we proved that the predictions of unitary quantum mechanics for an extended Wigner’s friend scenario are incompatible with any theory satisfying three metaphysical assumptions, the conjunction of which we call “Local Friendliness”: Absoluteness of Observed Events, Locality and No-Superdeterminism. In this paper (based on an invited talk for the QBism jubilee at the 2019 Växjö conference) I discuss the implications of this theorem for QBism, as seen from the point (...) of view of experimental metaphysics. I argue that the key distinction between QBism and realist interpretations of quantum mechanics is best understood in terms of their adherence to different theories of truth: the pragmatist versus the correspondence theories. I argue that a productive pathway to resolve the measurement problem within a pragmatist view involves taking seriously the perspective of quantum betting agents, even those in what I call a “Wigner bubble”. The notion of reality afforded by QBism, I propose, will correspond to the invariant elements of any theory that has pragmatic value to all rational agents—that is, the elements that are invariant upon changes of agent perspectives. The classical notion of ‘event’ is not among those invariants, even when those events are observed by some agent. Neither are quantum states. Nevertheless, I argue that far from solipsism, a personalist view of quantum states is an expression of its precise opposite: Copernicanism. (shrink)

Lawrence et al. have presented an argument purporting to show that “relative facts do not exist” and, consequently, “Relational Quantum Mechanics is incompatible with quantum mechanics”. The argument is based on a GHZ-like contradiction between constraints satisfied by measurement outcomes in an extended Wigner’s friend scenario. Here we present a strengthened version of the argument, and show why, contrary to the claim by Lawrence et al., these arguments do not contradict the consistency of a theory of relative facts. Rather, considering (...) this argument helps clarify how one should not think about a theory of relative facts, like RQM. (shrink)

This paper discusses John Hick’s response to the problem of religious diversity, based on the distinction between the Real itself and the way He is experienced and thought of by different religious communities. To this end, we divided this work into three sections in addition to the present introduction and the final considerations. In the first section we present the hickian concept of religious phenomenon and discuss the affirmation of him in favor of the ambiguity of the universe; the second (...) section is dedicated to the analysis of Hick’s defense of the rationality of religious belief and in the third section we present Hick’s pluralist hypothesis and some variations and criticisms of this hypothesis proposed by other authors. At the end we present some critical considerations about the success of Hick’s hypothesis to respond to the problem of religious diversity. (shrink)

This paper investigates continuities and changes in the definition of sickle cell disease in 1950s Brazil, taking into account that diseases have a history and are recognized as such according to the knowledge and perceptions available in a certain historical period and specific location. In the post-war era, new diagnostic tools, inheritance theories and, in particular, discussions on the concepts of race and racial relations, both nationally and internationally, were changing previous racialist and racist views. Nonetheless, the Brazilian medical interpretations (...) of sickle cell disease continued to racialize it and even use deep-rooted racist formulations to explain its symptoms or the existence of the disease. It is argued that the celebration of racial mixture and racial democracy might have concealed racist presumptions biasing the study of sickle cell disease. Although race as a biological concept gradually gave way to other genetic expressions, in Brazilian medical papers on sickle cell disease, race continued to influence the interpretation of the disease, along with the persistence of concepts of heredity through blood mixture.

O objetivo deste artigo é discutir o tratamento dos direitos humanos nos dois momentos de autoritarismo vividos no Brasil, na ditadura do Estado Novo e durante a ditadura militar. A partir de uma breve historicização do tratamento de questões relativas aos direitos fundamentais nas constituições de 1824 e 1891, demonstraremos como os regimes de exceção arquitetaram um conjunto jurídico que visava garantir a ação repressiva do Estado mantendo um conjunto significativo da população sob vigilância.

The primary focus of this article is a reading of Venus Hottentot 2000, a performance-text that reperforms the hyperbolization of Black female sexuality. In using the corporeality of the Black body as a strategic site of postcolonial resignification, this performance is moreover an interrogation of the colonial gaze that has fetishized the Black body. In foregrounding Venus Hottentot 2000 as a point of departure for exploration, the article proceeds by delving broadly into the representational history of the ‘Hottentot’ female. Furthermore, (...) to facilitate an understanding of the constitutive power of the colonial gaze and the possibilities of subverting and displacing that gaze from that of a postcolonial diasporic aesthetic practice, the article frames the postcolonial feminist reading of Venus Hottentot 2000 via an investigation of the processes by which the ‘Hottentot’ female has been festishized and scopically objectified within colonial discourse - processes whereby the ‘Hottentot’ female became a signifier of Black female sexuality. The article concludes by reading this performance as an example of a postcolonial ‘cultural war of positioning’, which offers moreover a contemporary rescripting of Black subjectivity. (shrink)

Plato's thought is as charming as the statues of Dedalus: it disappears into the meanders of the discourse, as soon as one proposes to establish with it a dominance relationship. The correct interpretation of Plato's thought demands the assumption of the Polis as the natural place from which it emerges, as the limitation which he proposes to surpass remounting to the Fysis and to the Being. In order to do it, it is important to catch its peculiar movement, starting from (...) the question about the being and visualizing the answer as the statement of its essence, i.e., of the eidos, and of its foundation, i.e., of Good as the proper name of Being. As it determines the being in its essence, the eidos is the measure of the whole adequacy, from the episteme to the Polis.O Pensamento de Platão tem o encanto das estátuas de Dédalo: esvai-se pelos meandros do discurso, tão logo se pretenda travar com ele uma relação de domínio. A sua correta interpretação exige que se assuma a Polis como o lugar natural no qual emerge, como a limitação que ele se propõe superar remontando à Fysis e ao Ser. Fazê-lo importa em captar o movimento que lhe é próprio, partindo da questão sobre o ente e visualizando a resposta como o enunciado de sua essência, isto é, do eidos, e de seu fundamento, isto é, do Bem como nome próprio do Ser. Determinando o ente em sua essência, o eidos é a medida de toda a adequação, da episteme à Polis. (shrink)

The 1964 theorem of John Bell shows that no model that reproduces the predictions of quantum mechanics can simultaneously satisfy the assumptions of locality and determinism. On the other hand, the assumptions of signal locality plus predictability are also sufficient to derive Bell inequalities. This simple theorem, previously noted but published only relatively recently by Masanes, Acin and Gisin, has fundamental implications not entirely appreciated. Firstly, nothing can be concluded about the ontological assumptions of locality or determinism independently of each (...) other—it is possible to reproduce quantum mechanics with deterministic models that violate locality as well as indeterministic models that satisfy locality. On the other hand, the operational assumption of signal locality is an empirically testable (and well-tested) consequence of relativity. Thus Bell inequality violations imply that we can trust that some events are fundamentally unpredictable, even if we cannot trust that they are indeterministic. This result grounds the quantum-mechanical prohibition of arbitrarily accurate predictions on the assumption of no superluminal signalling, regardless of any postulates of quantum mechanics. It also sheds a new light on an early stage of the historical debate between Einstein and Bohr. (shrink)

Certamente Sto. Agostinho jamais se propôs a escrever um tratado sistemático de Ética, ainda que o opúsculo sobre os costumes da igreja cristã e dos maniqueus possa representar um projeto desta ordem. Todavia, há em sua obra todos os elementos de uma ética, desde que se veja nesta a face humana do Deus Unitrino, isto é, a expressão de sua participação na Trindade, nos termos de uma indissociável unidade que abrange desde os princípios do humano à sua sobreelevação, a perfazer-se (...) no amor que unifica e une. Eis por que um tratado à parte seria inexequível se colocado no registro da vontade qual instância estanque em relação à inteligência e à memória. (shrink)

Este texto trata de certas comemorações de caráter profano dentro do espaço sagrado ou litúrgico. Além do carnaval, enfoca-se a Festa do Asno, notadamente a celebrada na cidade de Rouen, que compreendia uma procissão com grande aparato, acompanhada pelo clero e pelo povo.

O trabalho analisa as principais dificuldades na construção de parâmetros Tecnoéticos da atualidade. A hipótese aqui reside em determinar a constante que atravessa a Singularidade Tecnológica, a Convergência NBIC e a Inteligência Coletiva como variável integrativa e constitutiva da Tecnoética para fins de análise paradigmática sob a Teoria da Integridade de Dworkin. Assim, alicerçado no método lógico-dedutivo-dogmático, este artigo se baseia em incursões históricas e conceitos doutrinários para demonstrar a existência da constante em questão e, por fim, motivar sua adoção.

CAVALCANTI NETO, Lamartine de Hollanda. Contributions of Thomistic Psychology to the study of the plasticity of the ethos. 2012. 571s. Thesis (Doctorate in Bioethics) – Centro Universitário São Camilo, São Paulo,2012. If Ethics is not a static science, it is because ethos — its basic object of study — is a mutable reality. For this reason, ethical themes, chiefly those of Bioethics, are directly related to the study of the plasticity of the ethos. Nevertheless, such investigation requires that the (...) researcher distance himself from concrete ethical questions, to apply himself to the theoretical examination of what enables the existence and development of such questions — that is, the aforementioned plasticity. However, bibliographical literature on this subject has revealed a scarcity of works focused specifically on the theme. This scarcity seems to indicate that the subject is still in a process of methodological definition. Therefore, we propose as a research question, to investigate at the theoretical level, if Thomistic Psychology can be considered a valid study tool for the plasticity of ethos. For this aim, we adopt a documental and bibliographical research methodology adapted to the aforesaid question, based on the presupposition that such validity can be gauged to the extent that Thomistic Psychology offers objective contributions to the study of the plasticity of the ethos. Backed by extensive literature, we present an overview of Thomistic Psychology, as well as of ethos and its plasticity. With the data obtained, we establish a discussion with a view to identifying these contributions. Based on the results, we close with a reply, while still open, to our research question, hoping to afford, in this way, a kind of platform on which new studies can be developed with greater facility.

Este artigo questiona a dimensão crítica da democracia analisada por Sheldon S. Wolin. A partir da década de 1980, o impulso de Wolin de diagnosticar as falhas da democracia americana ao conectar o liberalismo ao totalitarismo se manifesta de uma nova maneira. Ele observa que, no processo de lutar ostensiva- mente contra o totalitarismo durante a Guerra Fria, o próprio governo americano passou a incorporar uma forma totalizante de poder. Essa crítica culmina em seu diagnóstico de uma crise do século (...) XXI: a condição neoliberal de “totalitarismo invertido”. Aqui Wolin argumenta não apenas que o sistema político americano compartilha algumas características com o totalitarismo, mas também que está começando a constituir uma nova versão do totalitarismo emergindo de dentro, e não em reação ao liberalismo. Palavras-chave: Democracia. Totalitarismo. Liberalismo. (shrink)

Este artigo tem como objetivo examinar o papel singular da música na reflexão de Nitzsche sobre o processo de criação poética, e analisar os efeitos de sua leitura da correspondência entre goethe e Schiller na elaboração dessa reflexão. Pretende-se mostrar, em seguida, como a análise da criação poética está associada a uma reflexão mais ampla sobre o pensamento e a linguagem.

This article aims to reflect on the genesis of The Birth of Tragedy based on Nietzsche's readings of Lectures on Fine Art and Literatur and Lectures on Dramatic Art by August Schlegel. Such readings, begun during his studies in Pforta, span his first years lecturing in Basel until they ultimately took shape in Nietzsche's first work. The goal is to analyze this trek of readings, in order to encover the development process of Nietzsche's thinking regarding the central issues of his (...) first work, such as the Apollonian and Dionysian, epic poetry and dramatic poetry.

O USO DOS DIREITOS HUMANOS COMO FUNDAMENTO DE INTERVENÇÃO NA SOBERANIA DOS ESTADOS.

As of 1869, and throughout the entire period during which he wrote the essay “On the Uses and Disadvantages of History for Life”, published in 1874, Nietzsche was a classical philology professor at the University of Basel. During this period, he reflected critically on theoretical and methodological questions in his field, emphasizing that if the study of Antiquity is to be linked to the analysis and critique of the sources, it loses, through this, contact with its own time, becoming knowledge (...) that is out-of-touch with the fundamental questions of its time. Nietzsche proposes establishing a different relationship with the past than that of the modern scientist: whereas the latter sees history from the perspective purely of knowledge, the professor from the University of Basel seeks a model in the past that is able to instigate reflection on the present, establishing a confrontation between distinct cultures, with different sets of values, so as to create some distance with the thought processes that are crystallized in modern times. This article intends to show how Nietzsche, from his notions of unhistory and supra-history, sought to investigate the value of history, contrasting the concept of the past as pure knowledge with a concept linked to life and action, that is able to generate the future.

O objetivo deste artigo é analisar as conexões entre o pensamento político de Nietzsche e sua crítica da cultura, tal como desenvolvidos nas notas e ensaios do primeiro período de sua obra, especialmente no ensaio Cinco prefácios a cinco livros não escritos. Trata-se de mostrar como o filósofo procura, a partir de uma singular análise do Estado e da sociedade na Grécia antiga, restituir à experiência política uma dimensão reflexiva em declínio na modernidade.

ABSTRACT In this article, I propose a dialogical analysis of five online cartoons which reverberate the discourse of the former president of Brazil (2019-2022) at the UN in September 2020, when he called the international community to combat Christphobia. Named after the same term, the cartoons present a framework of interdiscursive antagonism between Christian and the former President of Brazil’s fanatic followers’ positions. Assuming that cartoons are a privileged discursive genre for understanding the dialogical resonances between interlocutors and discourses, this (...) work approaches Christphobia as a responsive utterance in terms of scales of meaning. From the analysis, one can see a discursive game of incompatibility and estrangement, that makes room to a Christophobic “Other” in opposition to a persecuted “minority us,” as once presented during the UN discourse. There is an emphasis on a perception of religious intolerance as a result of the political agenda of the former president of Brazil’s religious-ideological alignment. (shrink)

A preocupação com a saúde física e mental de crianças, adolescentes, jovens, adultos e idosos tem crescido ao longo dos últimos anos, sobretudo a partir da pandemia de Covid-19. Tal preocupação tem produzido estudos e pesquisas acadêmicas; levantamentos e análises realizados por organizações nacionais e internacionais; políticas públicas nacionais; e orientações e planos de ação dirigidos às diversas nações. Se por um lado a atenção e o cuidado com as questões relativas à saúde física e mental são importantes e necessários, (...) por outro, fazem pensar no risco da medicalização da vida, do sofrimento e do mal-estar. Tendo em vista que a escola tem sido lócus privilegiado de discursos e práticas medicalizantes, foi realizada uma pesquisa com o objetivo de averiguar se o processo de medicalização é abordado na formação inicial de pedagogos e investigar os conhecimentos dos participantes sobre a temática. Para tal fim, foi aplicado um questionário em 19 (ex)estudantes de uma universidade pública federal através do aplicativo Google Forms. Dentre os resultados, a análise indica que o tema ainda é pouco estudado no curso e que há pouca clareza na definição e diferenciação dos termos medicalização, patologização e medicação, e na compreensão das causas e desdobramentos do processo.

A educação natural de Rousseau é uma tentativa de mostrar como as paixões, se liberadas da deformação provocada pela opinião social, podem ser moralmente corretas. Se o Emílio, afirma Rousseau, é um tratado sobre a bondade natural do homem, esta bondade está fundada sobre a liberdade, e, sobretudo, sobre a liberdade das paixões.

The First International and Interdisciplinary Conference on Modelling and Using Context, Rio de Janeiro, January 1997, gave rise to the present book, which contains a selection of the papers presented there, thoroughly refereed and revised. The treatment of contexts as bona fide objects of logical formalisation has gained wide acceptance, following the seminal impetus given by McCarthy in his Turing Award address. The field of natural language offers a particularly rich variety of examples and challenges to researchers concerned with the (...) formal modelling of context, and several chapters in the volume deal with contextualisation in the setting of natural language. Others adopt a purely formal-logical viewpoint, seeking to develop general models of even wider applicability. The 12 chapters are organised in three groups: formalisation of contextual information in natural language understanding and generation, the application of context in mechanised reasoning domains, and novel non-classical logics for contextual application.
