In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of (...) Miró Quesada’s theory of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J. C. Cifuentes and L. F. Bartolo Alegre.

Neste trabalho pretendo mostrar como o confronto com o materialismo reducionista de Thomas Nagel o fez voltar a defender concepções e explicações teleológicas advindas da teoria aristotélica. Nagel defende que deva existir uma ordem natural como tentativa de inteligibilidade que para além da explicação pelo viés da ciência física, deve conter outros elementos, ou seja, suspeita que deva incluir elementos teleológicos. É aqui que pretendo comparar a noção teleológica na argumentação de Nagel e de Aristóteles. Para além disso, incluirei como (...) Aristóteles e Nagel entenderam ideias pampsiquistas e mostrarei que a teoria aristotélica não é pampsiquista, como alguns pensam. (shrink)

In this paper, I seek to examine Deleuze’s fascination with “spiritual automata” as a counterpoint to his more famous notion, the “body without organs”. I shall argue that both are grounded in a deep reflection, on Deleuze’s part, on the problems and issues generated by Spinoza’s notion of parallel attributes. Ultimately, I argue, the development of the two notions is motivated by identical metaphysical worries regarding the tenability of transformation, persistence, and affective interrelations between individuals. The answer, for both thinkers, (...) is the insertion of a “third” relational term, which virtually interfaces with each without violation of their parallel development. For Spinoza, such term is the absolutely infinite substance; for Deleuze, it is instead the notion of sense and the faculty of sense-making. (shrink)

Neste artigo apresentaremos o que Donald Davidson entende por ação eracionalidade. Veremos o problema de eventos mentais causarem eventos físicose como o autor defende sua teoria do monismo anômalo. Isso implica explicar adiferença entre o que Davidson entende como um evento físico e um eventomental, e como podemos identificá-los para tentar racionalizar a ação. Aracionalidade engloba modos para tentar explicar mental e físico de formasdescritivas distintas, mas que de algum modo encontram-se na unidade dosujeito agente. Ao mesmo tempo que Davidson (...) reconhece a não identidade totalentre a explicação entre fenômenos físicos e mentais, ainda nomeia certo tipo deanomalia das leis mentais. -/- ABSTRACT -/- In this article, we will describe what the author Donald Davidson understands byaction and rationality.

The rationality encompasses ways of explaining both themental and the physical in distinct descriptive ways, but which somehowmeeting in the unity of the subject agent. (shrink)

Este trabajo parte del análisis de Heidegger en “¿Para qué poetas?”, donde el autor interpreta la poesía de Hölderlin a partir de su elegía «Pan y vino», aquí expondremos algunas de sus explicaciones. También intentaremos entender la respuesta que da Hölderlin en la que asocia los poetas a los «sacerdotes del dios del vino». Para ello nos ayudaremos de las nociones que de Dioniso nos ofrecen tanto Nietzsche como Hölderlin, presentaremos semejanzas y diferencias de algunas de sus interpretaciones. Aparte de (...) eso, reflexionaremos sobre la visión del artista como un dios y la relación existente entre la poesía y la filosofía. Concluiremos con las reflexiones que Heidegger hace en su trabajo “Aclaraciones a la poesía de Hölderlin”, donde el autor sobrevalora el papel de la poesía, considerando incluso que los poetas pueden llegar a esclarecer pensamientos de cualquier filosofía pensada a medias.

In this paper we will look at research by the philosopher of the mind João Fernandes Teixeira in "Uma nota sobre Sartre e Damásio ou as emoções entre a Fenomenologia e a Neurobiologia". From this we will analyze the theory of emotions of Jean-Paul Sartre in "Sketch for a Theory of Emotions" and of the neurobiologist António Damásio " Looking for Spinoza: Joy, Sorrow and the feeling Brain ". We will briefly discuss the theory of emotions of Jesse Prinz and (...) neuroscientist Robert Lent. Finally, we will propose that the synthesis for the quest to identify the meaning of emotions, as Sartre wanted, should involve combining different causal approaches to emotional phenomena to better understand the.

Pylyshyn restricts cognitively penetrable vision to late vision, whereas he does not make any distinction between different kinds of penetrating cognition. I argue that this approach disconnects early vision content from late vision content and blurs the distinction between the latter and the content of thought. To overcome this problem I suggest that we should not distinguish between different kinds of visual content but instead introduce a restriction on the kind of cognition that can directly penetrate visual experience. In particular, (...) I suggest that visual experience, unlike thought, is directly penetrated only by practical non-propositional knowledge. I specify this weak cognitive penetrability in anti-representational terms. In particular, I suggest that the dependence of visual content on practical non-propositional knowledge should be conceived as a rational non-inferential relation, for it is in this way that we can account for the distinctive content of visual experience.

In this short article, I analyze forms of public speech by individuals in positions of power through a framework based on Austin’s theory of speech acts. I argue that because of the illocutionary and perlocutionary force attached to such individuals’ offices and their public figures, their public speech qualifies for being framed as speech acts—which are not covered by even a broad understanding of freedom of speech or right to privacy. Therefore, I formulate a call for the assessment of public (...) speech by individuals in positions of power through a framework based on “linguistic responsibility.” This framework accounts for the peculiar power structure that such individuals can and do exploit to bring about considerable real-world effects through what could be understood as an exploitation of their speech act power.

Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...) past, present, and future are all equally real and there is nothing metaphysically special about the present. A third is perdurantism, according to which persisting material objects are made up of different temporal parts located at different times. We sketch routes from relativity to unitism and to the B-theory. We then discuss some routes to perdurantism, via the B-theory and via unitism. (shrink)

In this paper, I argue that the indirect realists’ recourse to mental representations does not allow them to account for the possibility of hallucination, nor for the presentational character of visual experience. To account for the presentational character, I suggest a kind of intentionalism that is based on the interdependency between the perceived object and the embodied perceiver. This approach provides a positive account to the effect that genuine perception and hallucination are different kinds of states. Finally, I offer a (...) tentative suggestion as to how a hallucinatory experience may still be mistaken for a genuine perceptual experience. (shrink)

No interior das discussões contemporâneas em astropolítica, há um pequeno grupo de defensores da chamada exopolítica. Este texto - sobre assuntos ontológicos em filosofia da astropolítica - avalia fundamentos conceituais em dois encaminhamentos vigentes em teorias exopolíticas. Para isso, leva-se em conta um ambiente mais abrangente fornecido por aspectos relacionados às investigações em astrobiologia teórica.

According to McDowell’s transcendental empiricism, the world view depends on experience, which in turn depends on the world view. This seems to be in accord with the thesis that experience is theory-laden, but it also seems to introduce a problem of vicious circularity. I argue that McDowell’s account has the resources to avoid the problem of vicious circularity by exploiting the idea of a wider circle that involves more relata and more kinds of rational dependence. But the acceptance of this (...) idea entails that experience, though concept-laden, is not theory-laden. (shrink)

Desde os tempos mais remotos, busca-se por equilíbrio entre o delito e a punição. Este artigo estabelece uma relação entre o conceito de Justiça em Aristóteles e a proporcionalidade em matéria penal. Para melhor compreensão do tema, inicia-se o estudo pelos principais pontos da obra Ética a Nicômaco, especialmente o Livro V, que trata da Justiça. A partir de então, aborda-se o princípio da proporcionalidade e a forma pela qual os conceitos de Aristóteles influenciaram a concepção desse princípio. Ato contínuo, (...) investiga-se a realidade atual do sistema carcerário, sendo avaliadas as estatísticas produzidas pelos órgãos competentes. Por conseguinte, enfatiza-se o Estado de Coisas Inconstitucional para verificar a questão penitenciária à luz da decisão da Suprema Corte brasileira na ADPF n. 347/DF. Ao final, pondera-se acerca da forma pela qual se pune no Brasil para investigar se suas premissas respeitam ou não as balizas do conceito de Justiça aristotélico e o princípio da proporcionalidade. Para o desenvolvimento desta pesquisa, utilizou-se o método qualitativo, por meio da leitura de obras que obedecem ao eixo temático exposto nos objetivos e que permitem o fichamento do repertório selecionado. Além de ter sido analisada juriprudência, foram coletados dados do censo penitenciário. Finalmente, articulou-se o material consultado com as estatísticas do sistema prisional. Concluiu-se nesta pesquisa que o Poder Executivo é omisso e ineficiente para garantir os direitos dos encarcerados, não obstante todo o avanço normativo sobre o tema. Como se não bastasse, na prática forense brasileira a proporcionalidade não é mais que mera previsão abstrata. (shrink)

Indagando a possibilidade e o sentido de uma poética do eu, será nosso objetivo clarificar, a partir do contributo incontornável do filósofo francês Paul Ricœur, de que forma o texto poéticose assume como uma mediação fundamental da compreensãodo si, bem como da sua configuração e refiguração enquanto um si mesmo. Neste sentido, atentaremos especialmente nas obras Temps et Récit (1983‑85) e Soi-Même Comme un Autre (1990), fulcrais para entendermos a relação que o filósofo tece entre narrativa, tempo e identidade, mais (...) especificamente a importância da mediação narrativa para a superação das apo‑rias ligadas às experiências humanas da temporalidade e da construção identitária. Gravitaremos, neste contexto, em torno da noção seminal de identidade narrativa –enquanto ponto de mediação entre uma identidade idem e uma identidade ipse. (shrink)

Resumo: Este trabalho é centrado em mostrar parte da propagação da Metafísica Contemporânea feita por Peter van Inwagen. Demonstraremos alguns argumentos do autor e suas respectivas análises sobre a validação do argumento dualista, dentre eles a comparação entre dois importantes e diferentes dualismos, especialmente o de Descartes e Leibniz. Van Inwagen aponta problemas nos dois argumentos. Por fim esclarece-nos muito sobre o problema da representação de fenómenos mentais versus representações físicas, o que explica um importante aspecto que contribui para o (...) surgimento do problema mente-corpo. -/- Abstract: This paper shows part of Peter van Inwagen’s propagation of contemporary metaphysics. We will demonstrate some of the author’s arguments and his respective analyses on validating the dualist argument, among them the comparison between two important and different dualisms, especially Descartes’ and Leibniz's. We will see that van Inwagen’s review points out problems in both arguments. Van Inwagen's review points out problems in both arguments. Finally, it sheds much light on the problem of the representation of mental phenomena versus physical representations, which explains an important aspect that contributes to the emergence of the mind-body problem.

This work tries to show that the metapoetic meditation developed by Ramos Rosa throughout his very extensive poetic work not only did not condemn his poetry to a cold cloister in the textual plane, but also contributed decisively to the opening to the real, to the effect of evidence and to the sense of communion that would become increasingly sensitive in his writing. To this end, we propose to clarify the thread that, under the aegis of the poetic lucidity consecrated (...) by the author, leads us from his metapoetic meditation to a poetic meditation of an ontophenomenological and sapiential nature, that is, from his metapoetry to a poetry whose wisdom provides a set of intuitions with a sapiential and philosophical accent. It is our intention to contribute, in this way, to the understanding of the (cognitive and ontological) demand and scope of Rosa’s poetic path, as well as, collaterally, to the debate around topics such as poetic (self-)reference, the ontological status of the poetic text or the philosophy-literature relationship.

De modo geral, este texto é uma incursão em lógica filosófica e filosofia da lógica. Ele contém reflexões originais acerca dos conceitos de paraconsistência, modalidades e cognoscibilidade e suas possíveis relações. De modo específico, o texto avança em quatro direções principais: inicialmente, uma definição genérica de lógicas não clássicas utilizando a ideia de lógica abstrata é sugerida. Em seguida, é mostrado como técnicas manuais de paraconsistentização de lógicas são usadas para gerar sistemas particulares de lógicas paraconsistentes. Depois, uma definição de (...) possibilidade lógica é proposta por meio da ideia de limites de sequências de fórmulas. Por fim, muitas abordagens distintas ao paradoxo de Fitch e, consequentemente, aos limites do conhecimento são apresentadas considerando as reflexões anteriores. (shrink)

In this paper we examine whether the sense of agency represents an obstacle to the project of naturalizing the mental. On the basis of a thought experiment we suggest that the sense of agency is not an epiphenomenon. We also examine Frith's attempt to explain in functionalist terms the sense of agency through the comparator and metarepresentational mechanisms. Through a variety of arguments we try to show that explanation by recourse to these mechanisms is inadequate. We conclude by suggesting that (...) one possible reason for the failure of the functionalist approaches is that they begin from the assumption that thought is a form a of willed action. (shrink)

Until recently, an almost perfect parallelism seemed to hold between theories of identity through time and across possible worlds,as every account in the temporal case(endurantism,perdurantism, exdurantism) was mirrored by a twin account in the modal case (trans-world identity, identity-via-parts, identity-via-counterparts). Nevertheless, in the recent literature, this parallelism has been broken because of the implementation in the debate of the relation of location. In particular, endurantism has been subject to a more in-depth analysis, and different versions of it, corresponding to different (...) ways an entity can be located in time, emerged. In this article, we provide a precise map of the conceptions at stake, complete the debate by introducing a version of endurantism not yet considered in the debate — we call transcendentism — and show that it allows us to provide an effective interpretation of the relation of trans-world identity and an intuitive solution in the temporal case.

In the debate about Christian attitudes to other religions, a threefold typology has emerged depicting differing Christian responses: pluralism, inclusivism and exclusivism. (This typology is not restricted to the Christian debate alone.) Traditionally, pluralism is opposed to exclusivism, the former claiming that it is arrogant and untenable to make exclusive truth claims, and that all religions are potentially equal paths to salvation and truth. In contrast, I argue that pluralism must always logically be a form of exclusivism and that nothing (...) called pluralism really exists. The main purpose of my paper is to show that there is no high-ground in the pluralist position, for in principle its logic is no different from the exclusivist position. If this is established, then the debate can proceed with more substantial issues regarding the justification and clarification of truth claims. (shrink)

Este trabalho analisará as influências da teoria aristotélica nas origens da fenomenologia, especificamente na investigação de Franz Brentano. Debruçaremos sobre a obra em que Brentano se afirma um aristotélico e compararemos com os seus intentos de destacar a psicologia como ciência juntamente com os fundamentos da fenomenologia. Para tal também desenvolveremos a importante noção de intencionalidade para a fenomenologia. E por fim, mostraremos que Brentano não nos parece tão aristotélico o quanto afirma.

Following a previous article (cf. Costa-Leite, A. (2018). Oppositions in a line segment, South American Journal of Logic, 4(1), pp.185-193) in which logical oppositions are defined in a line segment, this article goes one step further and proposes a method defining them using a zero-dimensional object: a point.

O que são práticas baseadas em evidências? Por que isso é importante para a Psicologia? Neste ebook Danielle de Souza Costa, Bruno Rezende de Souza, Clarice de Medeiros Chaves Ferreira e Leandro Fernandes Malloy-Diniz fazem uma breve introdução ao tema, conceituando o significado de termos chave como "evidências", "ciência" e "pseudociência", discutindo algumas das dificuldades que encontramos hoje na avaliação da confiabilidade dos estudos científicos, oferecendo dicas para os iniciantes, e destacando a importância do estudo de uma psicologia científica.

How to be being to be being/ next to the united and firm/ and trembling/ mouth of the poem?”, “How to say what is clearer than clarity [...]?” or “How to unite a light design and an obscure gesture?” These questions, as well as many others that emerge from the poetic and essay writing of António Ramos Rosa (1924-2013), represent different modulations of the same angular question: that of the relation between poem and reality, or, more radically, between poem and (...) being. And if such a question spreads into so many formulations it is because, in António Ramos Rosa, its scope is total, simultaneously aesthetic and ontological, metaphysical and spiritual. It is, therefore, this question that we will try to answer by looking into one of its possible faces: how can poetic creation be at the same time the most intimate gesture and the one that touches most deeply the undomesticated matter of the real, that absolute and unapprehensible Other?

A partir de la tesis del filósofo español Miguel de Unamuno (1864-1936), según la cual el extremo occidental — Portugal — y el extremo oriental — India — se dieron las manos espirituales por vía de la comprensión de la vanidad del mundo (vanitas), presentada en su obra Por tierras de Portugal y España (1911), nos proponemos poner en diálogo las visiones del mundo barroco occidental y del mundo budista oriental sobre la vanidad y la muerte. En este sentido, nuestra (...) reflexión se centrará en el pensamiento del P. António Vieira, como ejemplo capital del pensamiento barroco portugués, y en el Sermón de Benares, como texto fundador del budismo. (shrink)

This paper is a contribution to graded model theory, in the context of mathematical fuzzy logic. We study characterizations of classes of graded structures in terms of the syntactic form of their first-order axiomatization. We focus on classes given by universal and universal-existential sentences. In particular, we prove two amalgamation results using the technique of diagrams in the setting of structures valued on a finite MTL-algebra, from which analogues of the Łoś–Tarski and the Chang–Łoś–Suszko preservation theorems follow.

A partir de uma definição específica de sistema filosófico, este texto apresenta princípios condutores gerais para guiar o filósofo que deseja criar e propor sistemas. Além disso, este artigo mostra como tais complexos conceituais podem ser definidos com o uso de leis interativas, ligando noções de diferentes naturezas e esclarecendo a estrutura lógica dos sistemas filosóficos. Este artigo contém ainda comparações entre a presente abordagem e a recente desenvolvida por Puntel.

The article will expose the problem of the nature of reality stablished in the first sections of Wittgenstein"s “Tractatus Logico-Philosophicus”, especially the aphorisms 1 to 2.063 seeking to show points of contact between the Aristotelian-Thomistic and Suarezian thought. Initially, (I) a distinction is made between metaphysics and ontology in order to understand why Wittgenstein, notorious for his anti-metaphysical thought, actually ends up producing a theory of reality. Subsequently, (II) the relationship between reality and language will be drawn from the characteristic (...) isomorphism of the Tractatus in which a structural similarity will appear with the Aristotelian-Thomistic thought. This relationship will be the basis for (III) the construction of an ontological image of reality as the condition of possibility for a meaningful language. With this outlook, the (IV) hypothesis of the influence of Francisco Suárez"s thought as the content behind this Wittgensteinian description of reality will be advanced. (shrink)

Este artigo mostra que combinando as noções lógicas de 'contingência' e 'conhecimento' nós podemos formular uma tese cética de acordo com a qual 'o mundo não pode ser conhecido'. Além disso, ele mostra que tal tese é plausível do ponto de vista epistemológico.

The possibility of multi-location—of one entity having more than one exact location—is required by several metaphysical theories such as the immanentist theory of universals and three-dimensionalism about persistence. One of the most pressing challenges for multi-location theorists is that of making sense of exact location—in that extant definitions of exact location entail a principle called ‘functionality’, according to which nothing can have more than one exact location. Recently in a number of promising papers, Antony Eagle has proposed and defended a (...) definition of exact location in terms of weak location that does not entail functionality. This paper provides the first thorough assessment of Eagle’s proposal. In particular, we argue that it cannot account for the location of immanent universals, the multi-location of mereologically changing three-dimensional objects, the multi-location of mereologically complex objects, and that it makes extended simples impossible.
