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)

In order to demonstrate the great importance of Philosophy in the elaboration of current scientific theories, a parallel was drawn between concepts of pre-Socratic Philosophy and current modern theories. Thus, throughout this essay, the convergences between some elaborations developed by philosophers and their reinterpretation from a scientific point of view, supported by the scientific method and the present technological apparatuses, were exposed. In this sense, having as its core the reflection about the atomic theory of Leucippus and Democritus, we investigate (...) the way in which atomism dialogues with the modern Atomic Theory to the Quantum Theory, through concepts of Kosmos and Cosmology. In a second moment, origin of life theories were revisited from the pre-Socratic concepts of Psykhe. Finally, Philosophy and Science are brought together as possible and complementary tools for the restoration of the amplification of thought and investigative processes. (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 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)

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.

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 article presents the main features of the work of Domenico Vandelli, an Italian-born man of science who lived a large part of his life in Portugal. Vandelli’s scientific interests as a naturalist paved the way to his activities as a reformer and adviser on economic and financial issues. The topics covered in his writings are similar to those discussed by Linnaeus, with whom Vandelli corresponded. They clearly reveal that the scientific preparation indispensable for a better knowledge of natural resources (...) was also a fundamental condition for correctly addressing problems of efficiency in their economic allocation. The key argument put forward in this article is that the relationship between natural history and the agenda for economic reform and development deserves to be further analysed. It is indeed a central element in the emergence of political economy as an autonomous scientific discourse during the last decades of the eighteenth century.Author Keywords: Vandelli; Linnaeus; Natural History; Political Economy; Enlightenment.

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)

Con base en la hipótesis de que las leyes son fuentes de legitimación de las relaciones de dominación existentes en las sociedades capitalistas, aunque contradictorias, y que en este contexto, el abogado como especialista en el manejo de la ley, tiene una mayor importancia, en este artículo analizo los discurso políticos y legales de los abogados que han actuado y/o actuan en la asesoría jurídica de la entidad oficial que representa a empleadores rurales en el Brasil, denominada “Confederação de Agricultura (...) e Pecuária do Brasil” (CNA).

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.

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.

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. However, its dominance is not restricted to logic. As the dominance of the principle of reason is not restricted to epistemology and ontology. 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.

La Société qui vient [The Society to Come], a book edited by Princeton professor and current holder of the Chair of Public Health at the Collège de France, Didier Fassin, cannot be accused of sinning by modesty. This is a collective work of more than 1300 pages, grouped in seven parts and comprising no fewer than 64 chapters. 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)

According to Peirce one of the most important philosophical problems is continuity. Consequently, he set forth an innovative and peculiar approach in order to elucidate at once its mathematical and metaphysical challenges through proper non-classical logical reasoning. I will restrain my argument to the definition of the different types of discrete collections according to Peirce, with a special regard to the phenomenon called ?premonition of continuity? (Peirce, 1976, Vol. 3, p. 87, c. 1897).

This article inspects Peirce’s resonances on Deleuze’s semiotic. Whereas most of the literature agrees that Deleuze adapts Peirce’s semiotic to serve his Bergsonian-based theory of sign, this article claims that the relationship of Deleuze with Peirce’s writings is more foliated than it may appear at first. The development of this hypothesis invites to trace back Deleuze’s works before his very acquaintance with Peirce in the 1980s. Therefore, one of Peirce’s classical issues – the role that relations and habits play for (...) the triadic conception of sign – is considered with Deleuze’s early studies, in which he developed this same issue as to approach Hume and Proust. This background echoes years later in Deleuze’s incursion to Peirce’s semiotic in the 1980s ninety-two classes and two books on cinema. In fact, Deleuze’s own triadic conception of sign and his acknowledged pragmatist inclination prove to be closer to Peirce’s pragmatism than the scholarly literature tends to think or argue. The aim of this article is not, however, to build an overwhelming philosophical identity between Deleuze and Peirce, it sets up instead a steadier basis from where to understand their differences. Deleuze’s ignored five-year long lectures on cinema shows to be exegetically revealing with respect to his debts towards Peirce. (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.

Neste artigo pretendemos discutir a noção de construção da mente consciente a partir da perspectiva de Antonio Damásio. Para isso, centraremos nossa análise em Self comes to Mind. Em um primeiro momento é necessário delimitarmos o conceito de consciência na visão de Damásio, visando, com isso, a evitarmos equivocidades, na medida em que há várias definições de consciência. Acreditamos que, para uma melhor compreensão acerca do surgimento da mente consciente, é necessário levarmos em consideração os processos evolutivos aos quais o (...) homem está sujeito. A consciência é, pois, fruto de um desenvolvimento evolutivo já bem estabelecido pela ciência. Compreender o desenvolvimento evolutivo do self se torna tarefa de suma importância, na medida em que Damásio estrutura sua compreensão de mente consciente a partir do papel desempenhado pelo self na tarefa de agregar conteúdos mentais. Para Damásio, a origem da mente está associada ao momento em que um processo do self é adicionado a um processo mental básico. Quando não ocorre um self na mente, esta mente não é propriamente consciente, o que significa dizer que é o self que garante consciência a uma mente. Isso quer dizer que precisaremos discutir de forma clara e distinta o conceito de self e seus estágios, para que finalmente possamos entender os passos delimitados por Damásio para discutir a construção da mente consciente.
