Karl Popper and Paul Feyerabend were among the most influential philosophers of science of the twentieth century. Extensive studies have been dedicated to the development of their controversial relationship, which saw Feyerabend turning from a student and supporter of Popper to one of his harshest critics. Yet, it is not as well known that the rift between Popper and Feyerabend arose mainly in the context of their studies on the foundations of quantum mechanics, which has been the main subject of (...) their discussions for about two decades. This paper reconstructs in detail their diatribe over the foundations of quantum mechanics, emphasising also the major role that their personal relationship played in their distancing. (shrink)

Discussions on indeterminism in physics focus on the possibility of an open future, i.e. the possibility of having potential alternative future events, the realisation of one of which is not fully determined by the present state of affairs. Yet, can indeterminism affect also the past, making it open as well? We show that by upholding principles of finiteness of information one can entail such a possibility. We provide a toy model that shows how the past could be fundamentally indeterminate, while (...) also explaining the intuitive (and observed) asymmetry between the past—which can be remembered, at least partially—and the future—which is impossible to fully predict.

Given the recent interest in the fragment of system $\mathbf{F}$ where universal instantiation is restricted to atomic formulas, a fragment nowadays named system ${\mathbf{F}}_{\textbf{at}}$, we study directly in system $\mathbf{F}$ new conversions whose purpose is to enforce that restriction. We show some benefits of these new atomization conversions: they help achieving strict simulation of proof reduction by means of the Russell–Prawitz embedding of $\textbf{IPC}$ into system $\mathbf{F}$, they are not stronger than a certain ‘dinaturality’ conversion known to generate a consistent (...) equality of proofs, they provide the bridge between the Russell–Prawitz embedding and another translation, due to the authors, of $\textbf{IPC}$ directly into system ${\mathbf{F}}_{\textbf{at}}$ and they give means for explaining why the Russell–Prawitz translation achieves strict simulation whereas the translation into ${\mathbf{F}}_{\textbf{at}}$ does not.

IntroductionThis paper’s argument can be stated simply: first, the primary unacknowledged cause of modern warfare (that is, since the Great War of 1914–18) is neither “nationalism” nor “imperialism” (to name two popular bogeymen) but modern rationality itself, specifically the epistemological revolution embodied in the philosophy of the Prussian philosopher Immanuel Kant (1724–1804); second, the current Ukraine War is a case in point, one that interacts with contemporary transformations in Western culture (especially the abolishment of a sense of the objective reality (...) and meaning of male and female sexual differentiation) in ways that reveal the current Russia–Ukraine War as reprising—if it does not merely continue—the ideational conflict at the heart of the Great War, a conflict that emerges for the reasons set forth as the Ur-Krieg, or “source war,” of the historical era we inhabit. In making this argument, this paper will take its inspiration from the writings of the little-known Russian philosopher Vladimir Ern (1882–1917), and for this reason, we begin in a public lecture hall in Moscow in 1914.

ExcerptSecularity is not merely to deny the existence of God or obstruct the practice of religion; it is also, and even more precisely, to confine God to the practice of religion.

Este artigo investigou a interação dos fatores de risco e de proteção nos processos de resiliência de meninas vítimas de violência sexual, pela perspectiva bioecológica do desenvolvimento humano. Trata-se de uma pesquisa qualitativa, de cunho exploratório, com estudo de casos múltiplos. Foram realizadas entrevistas semiestruturadas com duas meninas de 11 a 12 anos, e seus respectivos responsáveis, que se encontravam em atendimento em um centro de referência a situações de violência sexual da rede de proteção de Porto Alegre/RS. Foi realizada (...) uma análise de conteúdo das entrevistas. Os resultados indicaram que, mesmo na presença de fatores de risco como a violência sexual, a existência de fatores de proteção a nível familiar, contextual e individual, contribuiu para a construção dos processos de resiliência. Ressalta-se a importância de fomentar uma maior integração da rede de assistência e proteção à criança para contribuir com os processos de resiliência em contextos de risco. (shrink)

Na questão 84, artigo 6 da Suma Teológica Tomás de Aquino apresenta o conceito de materia casuae para admitir a necessidade da participação do conhecimento sensível para que ocorra o conhecimento intelectivo. A noção de materia causae, evidencia o limite da atividade intelectiva, uma vez que o intelecto precisa da atualização sensível para que possa conhecer a natureza da coisa extra-mental. Assim, o conceito de materia causae aponta a dependência do intelecto em relação aos sentidos, sem que isso possa interferir (...) na autonomia de sua atividade. Desta forma, nos interessa investigar de que maneira a noção de causalidade pode ser tomada como justificativa para a relação entre o conhecimento sensível e a atualização intelectiva, sem ultrapassar o limite da ação de uma coisa corpórea sobre uma incorpórea.

Trata-se de um relato de experiência sobre o projeto “Prevenção: é um prazer falar sobre isso”, com o objetivo de fomentar ações de prevenção às Infecções Sexualmente Transmissíveis (ISTs) com o público universitário. Pautadas na abordagem da educação entre pares, foram realizadas 6 oficinas com universitárias dos cursos de saúde, culminando na produção de uma intervenção denominada Barraca do Tinder. A intervenção foi realizada numa universidade pública paranaense e visava expandir o alcance do projeto, produzindo discussão sobre sexualidade, vulnerabilidade e (...) prevenção através de abordagem participativa e lúdica junto ao público universitário. Discutimos os resultados do projeto, destacando o imaginário acerca da Aids, a vulnerabilidade relacionada a populações específicas, a efetividade da metodologia da educação entre pares e do uso de cenas sexuais como dispositivos de prevenção.

RESUMOPretende-se sustentar que para compreender o princípio da autonomia como princípio supremo da moralidade na Fundamentação, isto é, como a fórmula que contém em si as outras fórmulas do imperativo categórico, é preciso interpretá-la mediante o princípio da determinação completa. Conforme a indicação de Kant de que ocorre uma progressão entre as fórmulas, segue-se o fio condutor das formas lógicas da quantidade em direção às categoriasda quantidade, tal como estabelecido na Crítica da razão pura. Ora, se a concepção kantiana de (...) razão (em seus usos teórico e prático) pressupõe sua interpretação da lógica, então é de supor na relação entre as fórmulas do imperativo categórico a mesma relação que encontramos na combinação das categorias de quantidade.Palavras-chave: Kant, imperativo categórico, autonomia, determinação completa, categorias de quantidade, fiocondutor.ABSTRACTWe argue that to understand autonomy as the supreme principle of morality, that is, as the formula that contains the other formulas within itself, we have to understand it by means of the principle of complete determination. Following Kant’s remark that there is a progression among the formulas, we recall the problem of the guiding thread in the Critique of Pure Reason. Now, since Kant’s conception of reason (both theoretical and practical) dependson his logic, it seems that to understand the relationship among the formulas of the categorical imperative, we have to understand the relationship among 1) transcendental unity, logical universality and formula of universal law/law of nature; 2) transcendental plurality, logical particularity and formula of humanity; 3) transcendentaltotality, logical singularity and formula of autonomy/realm of ends.Key-words: Kant, Categorical Imperative, Autonomy, Complete Determination, Categories of Quantity, Guiding Thread.

In this paper, we reject commonly accepted views on fundamentality in science, either based on bottom-up construction or top-down reduction to isolate the alleged fundamental entities. We do not introduce any new scientific methodology, but rather describe the current scientific methodology and show how it entails an inherent search for foundations of science. This is achieved by phrasing metaphysical assumptions into falsifiable statements and define as fundamental those that survive empirical tests. The ones that are falsified are rejected, and the (...) corresponding philosophical concept is demolished as a prejudice. Furthermore, we show the application of this criterion in concrete examples of the search for fundamentality in quantum physics and biophysics. (shrink)

An examination of oracles in popular forms of Cuban espiritismo invites a rethinking of the role of “randomness” and “context” in the anthropology of divination. Through an analysis of the ways by which spirit mediums develop as persons, and their implications for the mechanics of divination, I argue that among espiritistas the meaning of particular configurations cannot be separated from the event that brings them about. Relatively simple in their properties (e.g. water), spiritist oracles function to provide impulse to a (...) perceived metaphysical universe that requires the generation of movement in order to achieve instantiation. The argument is that this movement provides a background of chaos essential to the purpose of divination. To demonstrate this, I forward an analogy to the language of electronic voice phenomena in parapsychology, in particular with its concept of “noise.” In both EVP and espiritismo, “noise” is the substance that allows spirits to communicate.

The purpose of the third section of Kant’s Groundwork is to prove the possibility of the categorical imperative. In the end of the second section, Kant establishes that a proof like this is necessary to show that morality is ‘something’ and ‘not a chimerical idea without any truth’ or a ‘phantom’. Since the categorical imperative was established as a synthetic a priori practical proposition, in order to prove its possibility it is necessary ‘to go beyond cognition of objects to a (...) critique of the subject, that is, of pure practical reason’. Kant names this kind of proof a deduction. The present paper intends to show the argument whose purpose is to justify the categorical imperative; show that the argument is a transcendental deduction; present the argument as it is reconstructed by Allison, and show that, although it seems compelling, the position of the commentator could not be accepted by Kant himself.
