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)

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)

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.

O HUMANISMO NA HERMENÊUTICA FILOSÓFICA: PARA ALÉM DO SÓCIOPOLÍTICO- ECONÔMICO.

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)

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)

Many of the computing systems programmed using Machine Learning are opaque: it is difficult to know why they do what they do or how they work. Explainable Artificial Intelligence aims to develop analytic techniques that render opaque computing systems transparent, but lacks a normative framework with which to evaluate these techniques’ explanatory successes. The aim of the present discussion is to develop such a framework, paying particular attention to different stakeholders’ distinct explanatory requirements. Building on an analysis of “opacity” from (...) philosophy of science, this framework is modeled after accounts of explanation in cognitive science. The framework distinguishes between the explanation-seeking questions that are likely to be asked by different stakeholders, and specifies the general ways in which these questions should be answered so as to allow these stakeholders to perform their roles in the Machine Learning ecosystem. By applying the normative framework to recently developed techniques such as input heatmapping, feature-detector visualization, and diagnostic classification, it is possible to determine whether and to what extent techniques from Explainable Artificial Intelligence can be used to render opaque computing systems transparent and, thus, whether they can be used to solve the Black Box Problem.

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.

To date, no definition of life has been unequivocally accepted by the scientific community. In frustration, some authors advocate alternatives to standard definitions. These include using a list of characteristic features, focusing on life’s effects, or categorizing biospheres rather than life itself; treating life as a fuzzy category, a process or a cluster of contingent properties; or advocating a ‘wait-and-see’ approach until other examples of life are created or discovered. But these skeptical, operational, and pluralistic approaches have intensified the debate, (...) rather than settled it. Given the failure of even these approaches, we advocate a new strategy. In this paper, we reverse the usual line of reasoning and argue that the “life problem” arises from thinking incorrectly about the nature of life. Scientists most often conceptualize life as a class or kind, with earthly life as a single instance of it. Instead, we advocate thinking about Earth’s Life as an individual, in the way that species are now thought to be. In this view, Life is a monophyletic clade that originated with a last universal common ancestor, and includes all its descendants. We can continue to use the category ‘life’ pragmatically to refer to similarities between various phenomena and Life. But the relevant similarities are a matter of interest and preference, not a matter of fact. The search for other life in the Universe, then, is merely a search for entities that resemble parts of Life in whatever sense astrobiologists find most appealing. This does not mean that the search for evolved complexity elsewhere in the universe or its creation in the lab are futile endeavors, but that debates over whether they count as ‘life’ are. Ironically, finally abandoning the concept ‘life’ may make our searches for evolved complexity more fruitful. We explain why. (shrink)

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.

This paper provides an exploratory comparative assessment of the institutional pressures influencing corporate social responsibility in a developed country, UK, vs. a developing country, Brazil, based on a survey of different actors. Information on sustainability concerns, organizational strategies and mechanisms of pressure was collected through interviews with environmental regulatory agencies, financial institutions, media and non-governmental organizations. Our results confirm that the more advanced awareness and CSR responsiveness in the UK is a consequence of a predominance of coercive and normative forces (...) on the organizational field. The institutional forces tend to build a Brazilian organizational field that is relational based and risk intensive. The findings lend support to the view that CSR responses are unlikely to be easily transformed into uniform standardized practices across the globe. This paper contributes to a collective understanding of the organizational field and a common template for CSR in the context of developed and developing countries. (shrink)

Em 1869, ano de início de sua atividade como professor na Universidade da Basiléia, Nietzsche desenvolve em inúmeros cursos e conferências uma reflexão sobre a experiência musical e poética, na qual enfatiza a união da palavra e da música na sensibilidade grega e sua separação na sensibilidade moderna. Esse tema será retomado nos anos seguintes, durante a redação de O nascimento da tragédia, seja na reflexão sobre a arte grega, seja na crítica à ópera moderna, dando lugar a uma investigação (...) sobre a diferença de natureza entre os domínios sonoro e linguístico, aos quais correspondem formas distintas de experimentar a arte. Pretendo, neste trabalho, mostrar como a rede de relações tecida por Nietzsche entre música e palavra permite elucidar não apenas a especificidade da música como arte, mas também a singularidade da experiência estética que ela torna possível.

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.

The received view of dynamical explanation is that dynamical cognitive science seeks to provide covering law explanations of cognitive phenomena. By analyzing three prominent examples of dynamicist research, I show that the received view is misleading: some dynamical explanations are mechanistic explanations, and in this way resemble computational and connectionist explanations. Interestingly, these dynamical explanations invoke the mathematical framework of dynamical systems theory to describe mechanisms far more complex and distributed than the ones typically considered by philosophers. Therefore, contemporary dynamicist (...) research reveals the need for a more sophisticated account of mechanistic explanation. (shrink)

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)

Models developed using machine learning are increasingly prevalent in scientific research. At the same time, these models are notoriously opaque. Explainable AI aims to mitigate the impact of opacity by rendering opaque models transparent. More than being just the solution to a problem, however, Explainable AI can also play an invaluable role in scientific exploration. This paper describes how post-hoc analytic techniques from Explainable AI can be used to refine target phenomena in medical science, to identify starting points for future (...) investigations of causal relationships, and to generate possible explanations of target phenomena in cognitive science. In this way, this paper describes how Explainable AI—over and above machine learning itself—contributes to the efficiency and scope of data-driven scientific research. (shrink)

This paper discusses the varieties of capitalism in transitional societies in Latin America and Central / Eastern Europe. The intended purpose of these transitions from semi-closed import-substituting economies in the first case and state socialist ones in the second was to institutionalize open-market economies. Twenty or thirty years later, there is a variety of types of capitalism in these countries, which I classify into three: open-market, neo-mercantilist, and anemic. The question for sociology is whether these quite different variants represent temporary (...) stages or distortions in the same process of transition or whether, on the contrary, they may institutionalize as discrete forms of peripheral capitalism. Neither standard “legacy” argu­ments nor institutionalist theories offer satisfactory answers to this question. The multiple modernities approach, on the other hand, is more appropriate as a theoretical perspective, but it has not produced yet specific propositions applicable to this question. My paper makes two claims. First, the successful transfer of institutions depends on the congruence between these institutions and the broader institutional framework of the recipient economies, a point not developed by institutionalist theories. I offer a hypothesis in this regard: Two critical nodes of congruence are the regulatory and extractive capacity of the state and the strength of civil society. Second, market capitalism (as liberal democracy as well) is a complex institution, and some of its components “travel” more easily across societies and institutional frameworks, and therefore are easier to institutionalize. This is the source of the hybrid variants. (shrink)

Martin Heidegger postula a recuperação da potência criativa da palavra como sendo a tarefa fundamental da fenomenologia, identificando na poesia a conservação dessa forma privilegiada de relação com a linguagem. O presente trabalho trata da linguagem como via de acesso às esferas primordiais do ser através de uma interpretação das experiências místicas como ocasiões para o rompimento do automatismo linguístico que impede ver na palavra algo além de um mero instrumento para a transmissão de informações. A partir das reflexões sobre (...) o símbolo desenvolvidas por pensadores como Gaston Bachelard, Paul Ricoeur, Mircea Eliade e Gershom Scholem, propomos uma conceituação fenomenológica do símbolo como entidade de sentido aberto, cuja origem remete ao positivamente indeterminado que constitui o “objeto” das experiências místicas. Positivamente indeterminado é a nossa expressão para dizer o divino, interpretando-o como fonte de todo sentido que é, por isso mesmo, ausente de qualquer sentido determinado, não por uma falta, mas por um excesso de significação. O excesso de significação se apresenta, então, como a chave para uma forma de relacionamento com a palavra concebida como força de criação. (shrink)

RESUMO: O objeto deste artigo é a noção de pós-modernismo, em torno da qual se travou um amplo debate que, num passado recente, alcançou grande projeção, e arrefeceu de modo algo abrupto. Buscaremos demonstrar que uma consideração crítica acerca do referido debate amplia nossa compreensão a propósito do capitalismo contemporâneo e, nesse sentido, por um lado, será realizado um esforço de apreensão conceitual, com o intuito de fixar as principais determinações do pós-modernismo. Por outro lado, tentaremos ancorar historicamente o debate (...) sobre o pós-modernismo, localizando certas articulações entre o desenvolvimento teórico e o processo histórico que lhe é subjacente. ABSTRACT: The object of this article is the notion of postmodernism, a topic around which was established a wide-ranging debate that achieved wide publicity in the fairly recent past. This debate, however, has since cooled abruptly. We will seek to demonstrate that a critical consideration of this debate enhances our understanding of contemporary capitalism. We first make an effort at conceptual apprehension, in order to establish the main determinations of postmodernism. We then try to historically anchor the debate on postmodernism, locating certain connections between its theoretical development and underlying historical processes. (shrink)

O objetivo dessa pesquisa é analisar o trânsito do conhecimento sobre inteligência de sinais, com foco em interceptação telefônica, utilizado pela polícia política brasileira estruturada a partir da Revolução de 1930, durante o primeiro governo do presidente Getúlio Vargas. Não demonstradas, em face da não localização de documentos comprobatórios, as participações do meio acadêmico e de agências policiais e de inteligência estrangeiras no trânsito desse conhecimento, a pesquisa centrou-se em duas hipóteses, cuja análise está direcionada aos documentos localizados em arquivos (...) públicos e privados. A primeira, de que o conhecimento sobre interceptação telefônica teria transitado dos campos de batalha da primeira guerra mundial na Europa, sendo transmitido pela Missão Militar Francesa ao Exército Brasileiro, que o teria repassado à polícia política nos anos 1930. A segunda, de que empresas de telefonia teriam colaborado com a polícia política, o que ficou demonstrado através do processo criminal 4057, localizado no Arquivo Público do Rio Grande do Sul.

At least since Kuhn’s Structure, philosophers have studied the influence of social factors in science’s pursuit of truth and knowledge. More recently, formal models and computer simulations have allowed philosophers of science and social epistemologists to dig deeper into the detailed dynamics of scientific research and experimentation, and to develop very seemingly realistic models of the social organization of science. These models purport to be predictive of the optimal allocations of factors, such as diversity of methods used in science, size (...) of groups, and communication channels among researchers. In this paper we argue that the current research faces an empirical challenge. The challenge is to connect simulation models with data. We present possible scenarios about how the challenge may unfold. (shrink)

Bayesian reverse-engineering is a research strategy for developing three-level explanations of behavior and cognition. Starting from a computational-level analysis of behavior and cognition as optimal probabilistic inference, Bayesian reverse-engineers apply numerous tweaks and heuristics to formulate testable hypotheses at the algorithmic and implementational levels. In so doing, they exploit recent technological advances in Bayesian artificial intelligence, machine learning, and statistics, but also consider established principles from cognitive psychology and neuroscience. Although these tweaks and heuristics are highly pragmatic in character and (...) are often deployed unsystematically, Bayesian reverse-engineering avoids several important worries that have been raised about the explanatory credentials of Bayesian cognitive science: the worry that the lower levels of analysis are being ignored altogether; the challenge that the mathematical models being developed are unfalsifiable; and the charge that the terms ‘optimal’ and ‘rational’ have lost their customary normative force. But while Bayesian reverse-engineering is therefore a viable and productive research strategy, it is also no fool-proof recipe for explanatory success. (shrink)

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.
