This paper is an attempt to solve the following problem: given a logic, how to turn it into a paraconsistent one? In other words, given a logic in which ex falso quodlibet holds, how to convert it into a logic not satisfying this principle? We use a framework provided by category theory in order to define a category of consequence structures. Then, we propose a functor to transform a logic not able to deal with contradictions into a paraconsistent one. Moreover, (...) we study the case of paraconsistentization of propositional classical logic. (shrink)

Some strategies to turn any logic into a paraconsistent system are examined. In the environment of universal logic, we show how to paraconsistentize logics at the abstract level using a transformation in the class of all abstract logics called paraconsistentization by consistent sets. Moreover, by means of the notions of paradeduction and paraconsequence we go on applying the process of changing a logic converting it into a paraconsistent system. We also examine how this transformation can be performed using multideductive abstract (...) logics. To conclude, the conceptual notion paraconsistent orbit of a logic is proposed. (shrink)

This paper shows how to transform explosive many-valued systems into paraconsistent logics. We investigate mainly the case of three-valued systems exhibiting how non-explosive three-valued logics can be obtained from them.

In Brazil, the CNPq (National Council for Scientific and Technological Development) provides grants, funds and fellowships to productive scientists to support their investigations. They are ranked and categorized into four hierarchical levels ranging from PQ 1A (the highest) to PQ 1D (the lowest). Few studies, however, report and analyse scientific productivity in different sub-fields of Biomedical Sciences (BS), e.g., Biochemistry, Pharmacology, Biophysics and Physiology. In fact, systematic comparisons of productivity among the PQ 1 categories within the above sub-fields are lacking (...) in the literature. Here, the scientific productivity of 323 investigators receiving PQ 1 fellowships (A to D levels) in these sub-fields of BS was investigated. The Scopus database was used to compile the total number of articles, citations, h-index values and authorship positions (first-, co- or last-listed author) in the most cited papers by researchers granted CNPq fellowships. We found that researchers from Pharmacology had the best performance for all of the parameters analysed, followed by those in Biochemistry. There was great variability in scientific productivity within the PQ 1A level in all of the sub-fields of BS, but not within the other levels (1B, 1C and 1D). Analysis of the most cited papers of PQ 1(A–D) researchers in Pharmacology revealed that the citations of researchers in the 1C and 1D levels were associated with publications with their senior supervisors, whereas those in the 1B level were less connected with their supervisors in comparison to those in 1A. Taken together, these findings suggest that the scientific performance of PQ 1A researchers in BS is not homogenous. In our opinion, parameters such as the most cited papers without the involvement of Ph.D. and/or post-doctoral supervisors should be used to make decisions regarding any given researcher’s fellowship award level.

Apresentaremos as possíveis aplicações pedagógicas das suas reflexões, como a utilização da imprecisão científica de Heisenberg e da concepção de técnica em Heidegger, a partir da análise histórico-filosófica dos seus escritos, tomando-os como fundamentação a necessária e significativa melhoria da educação técnico-científica.

The main goals of this study were, to test the motivational determinants of athletes perceived effort in football considering the four-stage motivational sequence at the contextual level proposed by Hierarchical Model of Intrinsic and Extrinsic Motivation: task-involving, basic psychological needs, self-determined motivation and perceived effort. The multi-group analysis across different age-groups (U15, U17, U19, U21 years) and mediation role of basic psychological needs and self-determined motivation on the task-involving climate and the perceived effort were also analysed. Two independent samples of (...) male football athletes (N= 403, N= 403), aged 13-20 were enrolled in this study. The results demonstrated that structural model provided a good fit to data for all samples under analysis, and was invariant across U17, U19, and U21. However, it was not invariant across U15 and U17, U19 and U21. Additionally, in the results from the mediation analysis, there were significant indirect effects in all samples, supporting theoretical by self-determination theory assumptions, reinforcing the importance of basic psychological needs satisfaction and behavioral regulation in the relation in analysis. The results allow concluding that when coaches promote a task-involving climate, the basic psychological needs satisfaction of athletes improves. This climate will facilitate the regulation of their behaviors towards more autonomous forms of motivation, with positive results in the perceived effort of the athletes. (shrink)

We start by problematizing the way in which philosophical practice is generally conceived in our academic environment. In this article, we address an understanding of Philosophy as a process of serious and sincere investigation of existential questions and creation of theory. With this, we intend to question some of the most common diagnoses and solutions for the underdevelopment of philosophical practice in Brazil, as well as provide our contribution to the propagation of a philosophical practice that risks the leap from (...) commentary to creation.

Given the need to explore the factors that can account for a better understanding of the intention-behavior gap in exercise practice in health club settings, and considering the emergence of hedonic assumptions related to exercise adherence, this cross-sectional study aimed to test the moderation effect of the intensity traits agreement/disagreement in three relevant outcomes of exercise enjoyment: exercise habit, intention to continue exercising, and exercise frequency. A sample consisted of 273 exercisers (male = 127; Mage = 36.21; SD = 11.29) (...) enrolled in nine health clubs who voluntarily fulfilled a battery of questionnaires. All analyses were performed using SPSS v. 23.0/PROCESS v. 3.5. The results of the study presented a moderation effect of exercise intensity traits agreement on three relevant enjoyment outcomes: exercise habit, intention to continue exercising, and exercise frequency. No relevant results emerged from intensity traits disagreement. The results suggest that assessing and tailoring exercise prescription and supervision in order to customize exercise intensity may influence future exercise participation. (shrink)

In the Transcendental Dialectic of the Critique of Pure Reason (1787), Kant argues for the impossibility of theistic arguments, namely the ontological, cosmological, and physico-theological arguments. However, his objection relies on his classification of theistic arguments, which has been criticized by analytical philosophers of religion such as Plantinga (2012) and Swinburne (2019). Therefore, this paper aims to critically investigate two problems related to this classification: the systematic criteria of its classification and the historical sufficiency of its three theistic proofs. Regarding (...) the first problem, it will be argued that it is possible to recognize a certain systematic artificiality in Kant's classification of theistic proofs, given the criticisms of Strawson (1966) and Hegel (1812, 1830), as well as the internal critique developed by the authors of this work. Regarding the second problem, it will be argued that it is possible to indicate a certain historical insufficiency in Kant's classification of the three theistic proofs, based on brief critiques focused on some classical theologians such as Anselm, Aquinas, and Al-Ghazali. Finally, once it is justified that Kant's objection depends on this possibly artificial and insufficient classification, it will be briefly indicated that Kant does not seem as justified as he intended in his objection to theistic arguments.

Em um artigo intitulado “Whether certainty is a form of life”, Elizabeth Wolgast ataca por duas vias diversas a concepção witgensteiniana de proposição gramatical desenvolvida no Da Certeza. Ela acusa Wittgenstein de contradizer certas teses centrais das Investigações Filosóficas, ao estabelecer como significativas proposições sem uso em nossos jogos de linguagem correntes, e denuncia a precariedade da tese, supostamente presente no Da Certeza, de que proposições gramaticais descrevem nosso sistema de crenças. Procuro refutar ambas as objeções por meio de uma (...) apresentação de evidências de que proposições gramaticais podem ter uso efetivo em jogos de linguagem correntes, e da demonstração de que uma mesma proposição pode, a um só tempo, descrever o uso das palavras em uma língua e servir como exemplo (modelo) de uso. Busco apoio no artigo de Debrah Aidun, “Wittgenstein on gramatical propositions”, para efetuar essa investigação sobre o estatuto das proposições gramaticais e faço complementações a seus argumentos de modo a aproximar o último Wittgenstein das pesquisas sobre os atos de fala conforme desenvolvidas por Austin e Searle.

Tentativa de estabelecer um monismo pulsional a partir do conceito nietzschiano de vontade de poder e o conceito freudiano de princípio de prazer. Nossa intenção é unificá-los na ideia de uma pulsão existencial originária, presente e efetivamente atuante em todos os processos existenciais – a pulsão de poder absoluto.

Trata-se de compreender a noção de vizinhança comunicante criada por Franklin Leopoldo e Silva para pensar a relação entre os textos filosóficos e literários de Sartre, e ensaiar uma ampliação do alcance da expressão, tanto no que se refere ao modo como o próprio filósofo francês pensa a relação entre arte e filosofia, quanto na proposta de uma metodologia que nos permitiria desvelar uma coerência no pensamento sartriano. Por fim, coloca-se a noção de vizinhança comunicante como uma proposta para pensar (...) prática e teoricamente o fazer filosófico e o ensino de filosofia na contemporaneidade. (shrink)

We present a kind of logic named multideductive logic and outline an application of it in the problem of theoretic-formal unification of physical theories dealing with the Bohr atom theory. This is just a preliminary study that will be developed in future papers.

Through skepticism and dialectics, German idealism transformed our understanding of the world and ourselves. This book shows how Kant, Fichte, Schelling, and Hegel revolutionized reason and made possible the critical reversal of values present in 20th-century philosophy.

In this paper, we intend to demonstrate that the asylum request process can have its semantic and politic structures evidenced from an access via philosophy of language. In order to elucidate the normative nature of this social practice and to take a critical stance in relation to the treatment given to the refuge interview as it has been done in our country, we resort to certain concepts developed by the so called later Wittgenstein. Looking for a more complete treatment of (...) our object of study, we also turn to the authors of Bakhtin’s Circle, which explore communicational dimensions that the Viennese philosopher did not properly explore – with special emphasis on “value accents”. In order to collect empirical evidence relevant to our purposes, a field research was carried out with professionals and volunteers involved in the asylum request interviews. The resulting reports provided us with more basis for the considerations we make about the normative fragility of the interview language game and the intricate value system that guides the interaction between interviewer, interpreter and interviewee.

No presente trabalho, procuro mostrar que um esclarecimento prévio acerca do papel da metáfora nas barganhas de significado é elemento imprescindível para a constituição de uma Filosofia da Retórica. Para tanto, recorro ao tratamento precursor conferido por I.A. Richards ao tema da metáfora na obra intitulada The Philosophy of Rhetoric e proponho complementações ao mesmo a partir de uma concepção de aprendizado da linguagem de orientação wittgensteiniana.

This essay considers insects’ place-making powers in history of science topics. Insects have co-shaped the geographies of knowledge production throughout history in three primary dimensions: through their size, density, and multiplane existence. Insects’ miniature worlds have helped humans to create trans-scale analogies. Their spatial transgression and swarming capacity have overwhelmed people, including field researchers, contributing to the making of the places where science is produced. Finally, insects’ “ontologically alien” ways of engaging with environments (e.g., flying and living underground) have offered (...) valuable material for humans’ imaginings of their own realities. By prioritizing insects’ own spatial characteristics, this tripartite typology of human/insect entanglements intends to spur new ways of writing histories of science that engage with space and place.

Nesta comunicação exploro aquele que deve ser o objecto e o âmbito de uma teoria de justiça. Da resposta a estas duas questões depende a possibilidade de definir princípios de justiça que concebam uma sociedade justa. Assim, tenho em consideração as propostas sobre o objecto e o âmbito da justiça presentes nas teorias de Nozick (libertária), de Rawls (igualitária) e de Walzer (comunitária) e avalio topicamente cada uma das posições. Concluo tentando responder à questão: qual deve ser o objecto e (...) o âmbito de uma teoria de justiça? (shrink)

Investigation on the ethical implications of the principle of identity and of the principle of reason. The logical principle of identity (A=A), along with the principle of non­contradiction and the principle of the third middle costitute the basis of ocidental logic.

This principles constitute a whole worldvew with serious ethical implications. We’ll try, at the end of the (...) article, to indicate contemporary alternatives to this principles – alternatives which bring with themselves different ethical implications. (shrink)

Is it possible a thought that resists the temptation of an absolute basis, but also to unbridled fury calculator machination? It is also possible that a thought is put in a position to understand and also to position itself critically in relation to both nostalgic fundamentalisms, and to pure effectiveness and productivity that technoscience imposes on us? It is possible, after all, to distance itself from traditional metaphysics without falling back into naivety "anti-metaphysical" definitive and safe overcome? Is it still (...) possible to conceive any kind of “ other" metaphysics? From this initial universe of questions we seek to point out that the metaphysics of the will, at least as developed by Nietzsche and psychoanalysis, brings to the fore a dimension "strange" to the Western metaphysical tradition: the instinctual dimension, this historical third middle between matter and spirit, body and mind, unity and multiplicity, sameness and difference, setting another metaphysical not reducible to traditional metaphysics, nor simply anti-metaphysical.

Portuguese: Thomas Nagel propõe uma conceção de objetividade que ele designada por “a perspetiva de lado nenhum”. Dependendo da área de conhecimento à qual será aplicada, esta perspetiva tem como requisito diferentes níveis de distanciamento de posições subjetivas. Todavia, de acordo com Jonathan Dancy e Alan Thomas, Nagel propõe dois modelos diferentes de objetificação, em vez de apenas um. Partindo das inter- pretações destes autores, mas acabando por divergir deles, proponho que estes dois modelos de objetificação são, na verdade, semelhantes. (...) O elemento fundamental para chegar a esta conclusão está no significado que “reflexão crítica” tem em cada um dos modelos. Neste artigo, argumento que “reflexão crítica” tem apenas um significado: distanciamento. Consequentemente, concluirei que a conceção de objetividade proposta por Nagel terá que ser entendida como excluindo perspetivas subjetivas. Mais especificamente, concluirei que esta conceção requer distanciamento absoluto de perspetivas subjetivas, independentemente da área de conhecimento em consideração. -/- /////// English: Thomas Nagel defends a conception of objectivity as the view from nowhere. This view, ideally, would require different degrees of detachment from subjective positions, depending on the area of knowledge to which it would be applied. However, in doing this, and according to Jonathan Dancy and Alan Thomas, Nagel formulates two different models of objectification. Starting from these authors’ interpretations, but essentially diverging from them, I argue that the two models of objectification are, in fact, similar. The key element to reach this conclusion is the meaning of “critical reflection” in each one of the models. Given my argument that “critical reflection” has only one meaning – detachment –, Nagel’s conception of objectivity cannot include subjective perspectives in it; in fact, it requires absolute detachment from those subjective perspectives, independently of the area of knowledge being considered.

Philosophie des expérientes radicales, livro recém-publicado pelo filósofo pragmatista e professor da Universidade de Lyon III, Stéphane Madelrieux, propõe uma maneira original e inovadora de ler a filosofia francesa do século XX. Sem abordá-la por caminhos tradicionais, tais como a sucessão cronológica de gerações (1860, 1900, 1900, etc), conceitos típicos (espírito e vida; existência e transcendência; dialética e práxis; estrutura e descontinuidade; diferença e desconstrução, etc.), correntes hegemônicas (espiritualismo bergsoniano, filosofias da vida; existencialismos; hegelianismos, marxismos; estruturalismo, epistemologia histórica; pós-estruturalismo ou (...) pós-modernismo, etc.), Madelrieux elege seis autores franceses (Henri Bergson, Jean Wahl, Gilles Deleuze, Georges Bataille, Maurice Blanchot e Michel Foucault), todos do século XX, para, em seguida, analisá-los pelo prisma do "empirismo metafísico". O que interessa a Madelrieux é apontar a presença de um programa inédito, não trabalhado na literatura filosófica, que amarra experiência e metafísica, e que explica uma parte importante da filosofia do século XX, notadamente na França.

Each chapter is devoted to a fundamental question of our present time and is written by an author who is an expert in (...) her or his domain or field of research. Each of the first six parts deals with a set of broad themes of general interest: ‘challenges ( enjeux), policies, worlds, inequalities, recognition and exploitation’. A seventh, final, and non-thematic part is free of a prior theme and is composed of non-French authors. (shrink)

Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is (...) affected by feelings of randomness. In a between-subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem-solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed. (shrink)

Veremos neste artigo como Friedrich Nietzsche propõe um retorno à força esquecida da linguagem, no sentido de uma retomada, uma recuperação de uma dimensão mais originária da linguagem, para além de suas funções comunicativa, utilitária, acadêmica e científica. Além de teorizar sobre o tema, podemos notar em sua obra um esforço sempre renovado para extrapolar os domínios familiares da linguagem e explorar suas dimensões mais originárias que restam esquecidas, abrindo assim um leque de novas possibilidades.

O presente artigo parte da problemática: qual a forma de repressão estatal brasileira relativa às fake news? Como provável hipótese de pesquisa tem-se que o Estado brasileiro não tem sido eficiente em dirimir este problema, carecendo de regulamentação específica. O objetivo geral consiste em analisar a atuação do Estado em relação à contenção de fake news. Para tanto, utilizou-se o método de procedimento dedutivo e o de pesquisa bibliográfico. Como conclusão, percebe-se que o Estado brasileiro não consegue alcançar o fenômeno (...) das fake news e a repressão acaba ficando a cargo da iniciativa privada. (shrink)

Dentre os vários modelos normativos de democracia elaborados na Filosofia Política, um dos mais influentes é o da democracia deliberativa, cuja característica mais essencial é a exigência de justificação pública. John Rawls, ao estabelecer as bases do que ele chamou de razão pública, tornou-se um dos principais marcos teóricos desse modelo democrático. Atrelado à razão pública, Rawls tratou do dever de civilidade, um dever moral coerente com ela e com a sua ideia de democracia. O cidadão que o cumpre colabora (...) com a construção e manutenção da própria democracia. O escopo do presente artigo é, à luz da teoria rawlsiana, estabelecer quatro componentes de naturezas distintas e aparentemente contraditórias (singular, plural, subjetivo e objetivo) que, somados, completam o dever de civilidade, tornando-o essencial para o regime democrático.

A soberania é um conceito cuja definição remete para o absoluto e o incondicionado, pese embora a sua génese se situar na modernidade, o que significa ter de se prescindir, na sua formulação, de qualquer recurso de natureza transcendente, como os que serviam de lastro à legitimação do poder nas concepções antiga e medieval.
