Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human. Here we show that alarm-calls such as those used by African vervet monkeys (Cercopithecus aethiops), logically satisfy the semiotic definition of symbol. We also show that the acquisition of vocal symbols in vervet monkeys can be successfully simulated by a computer program based on minimal semiotic and neurobiological constraints. (...) The simulations indicate that learning depends on the tutor-predator ratio, and that apprentice-generated auditory mistakes in vocal symbol interpretation have little effect on the learning rates of apprentices (up to 80% of mistakes are tolerated). In contrast, just 10% of apprentice-generated visual mistakes in predator identification will prevent any vocal symbol to be correctly associated with a predator call in a stable manner. Tutor unreliability was also deleterious to vocal symbol learning: a mere 5% of “lying” tutors were able to completely disrupt symbol learning, invariably leading to the acquisition of incorrect associations by apprentices. Our investigation corroborates the existence of vocal symbols in a non-human species, and indicates that symbolic competence emerges spontaneously from classical associative learning mechanisms when the conditioned stimuli are self-generated, arbitrary and socially efficacious. We propose that more exclusive properties of human language, such as syntax, may derive from the evolution of higher-order domains for neural association, more removed from both the sensory input and the motor output, able to support the gradual complexification of grammatical categories into syntax.

Ophiocordyceps is a fungal pathogen of ants of the tribe Camponotini. It is called zombie fungus, since it changes the host behavior, causing them to die in an exposed position, typically clinging onto and biting into the adaxial surface of shrub leaves. This study aimed to describe the occurrence of parasitic associations between Ophiocordyceps and ants of the genus Camponotus in an urban fragment of Atlantic Rainforest in southeastern Brazil and to measure the rate of hyperparasitism in Ophiocordyceps by other (...) fungi in the same location. We found 57 individuals of four species of ants and three species of fungus. The age categories of fungi were equally distributed, and rate of hyperparasitism was 17.5% (n = 10). The sampled area was recognized as an important site of Ophiocordyceps occurrence. (shrink)

The aim of this paper is to make the case for the obstinacy thesis. This is the thesis that proper names like ‘Hitler’, demonstratives like ‘this’, pure indexicals like ‘I’, and natural kind terms like ‘water’ and ‘gold’, are obstinately rigid terms. An obstinately rigid term is one that refers to the object that is its actual referent with respect to every possible world (hence, a fortiori, even with respect to worlds where that object does not exist). This form of (...) rigidity is stronger than the usual Kripkean one and has been notoriously explored by David Kaplan (Kaplan 1989a: 492-3; Kaplan 1989b: 569-71). Yet, the obstinacy thesis seems implausible to many philosophers and is worth substantive argument. For convenience, we focus our attention on proper names; but most of our remarks could be easily generalized to other unstructured singular terms. We shall take for granted Saul Kripke’s semantical doctrine that proper names are rigid in the general sense of the term and argue that their rigidity should take the specific form of obstinacy rather than persistence.

Neste ensaio, exploro como os princípios filosóficos de Kant podem oferecer uma abordagem que aindahoje é relevante para lidar com discursos intolerantes. Apresento a distinção entre o uso público e o uso privado darazão para Kant, visando demonstrar que, segundo o autor, um representante público eleito democraticamente quedefende ideias antidemocráticas deveria renunciar ao seu cargo. Utilizando-me do raciocínio do paradoxo datolerância de Popper, mostro que ser intolerante com discursos antidemocráticos é uma condição necessária parauma democracia existir. Porém, a partir de (...) um argumento parcialmente transcendental, mostro que isso não pode seaplicar a um indivíduo que acredita em um discurso antidemocrático. Ainda assim, mostro que podemos extrairconsiderações importantes a partir disso, a saber: o indivíduo antidemocrático está lutando pelo seu “direito” deexpressar somente seu próprio ponto de vista, enquanto o indivíduo genuinamente tolerante/democrático defende apossibilidade de vários pontos de vistas divergentes coexistirem.

In this paper, we intend to discuss if and in what sense semiosis (meaning process, cf. C. S. Peirce) can be regarded as an "emergent" process in semiotic systems. It is not our problem here to answer when or how semiosis emerged in nature. As a prerequisite for the very formulation of these problems, we are rather interested in discussing the conditions which should be fulfilled for semiosis to be characterized as an emergent process. The first step in this work (...) is to summarize a systematic analysis of the variety of emergence theories and concepts, elaborated by Achim Stephan. Along the summary of this analysis, we pose fundamental questions that have to be answered in order to ascribe a precise meaning to the term "emergence" in the context of an understanding of semiosis. After discussing a model for explaining emergence based on Salthe's hierarchical structuralism, which considers three levels at a time in a semiotic system, we present some tentative answers to those questions.

In a review of Frege's Puzzle1, Graeme Forbes makes the claim that Salmon's account of belief might be seen, under certain conditions, as a mere notational variant of a neo-Fregean theory; and thus that such an account might be reduced to a neo-Fregean one simply by rewriting it in terms of Fregean terminology. With a view to supporting his claim, Forbes offers an outline of an account of belief which, according to him, would satisfy the following conditions: (i) it could (...) be directly obtained from Salmon's own analysis by means of a certain set of substitutions, which presumably would not affect the essential features of Salmon's view; (ii) it could naturally be described as Fregean, in the sense that it would preserve, (at least) the spirit of Frege's doctrines, especially his fundamental intuitions about belief. Of course, the upshot of Forbes's argument is that Salmon's theory would not, at bottom, constitute a genuine alternative to a Fregean semantics for belief ascriptions. In this paper I argue to the effect that Forbes's claim is not in general sound. It seems to me that the sort of indirect argument used by Forbes - that of trying to undermine Salmon's theory by showing that it is just a version of a neo-Fregean account - does not provide someone working within a Fregean framework with an adequate strategy to counter Salmon's neo-Russellian views. It would perhaps be better to concentrate a Fregean attack on certain apparently dubious and highly controversial theses and results which are constitutive of Salmon's view, e.g. the counterintuitive character of a substantial set of consequences which follow from his theory of belief, as well as the associated revisionist stand he is forced to take towards our current patterns of speaking about belief.

O presente artigo incide sobre o conceito de expressão no âmbito do pensamento leibniziano, pretendendo, a partir da sua análise, expor a crítica que Fernando Gil lhe tece, nomeadamente no que diz respeito à ideia de “causalidade expressiva”. Passando por vários conceitos leibnizianos como “substância simples”, “força”, “apetição” ou “entre-expressão”, o que se pretende analisar é a reflexão de Fernando Gil relativamente àquilo que o autor considera “a aporia da expressão leibniziana”, e, ainda, a sua reabilitação da inteligibilidade expressiva como (...) pensamento do contínuo, onde inteligibilidade, beleza e simplicidade se implicam mutuamente.

This paper aims of is to present Richard Rorty’s Philosophy of Education, through his analysis of the education as being divided into two distinct processes: socialization and individualization. Thereafter, it is intended to show two critiques, of conservadorism and elitism, that are addressed to these processes. Finally, a redescription of the Rorty’s positions will be proposed, by assigning a reformist character to its apparent conservatism and a private character to the supposedly elitist individualization, in order to weaken the strength of (...) those critics.

Philosophers and social scientists of diverse orientations have suggested that the pragmatics of semiosis is germane to a dynamic account of meaning as process. Semiosis, the central focus of C. S. Peirce's pragmatic philosophy, may hold a key to perennial problems regarding meaning. Indeed, Peirce's thought should be deemed seminal when placed within the cognitive sciences, especially with respect to his concept of the sign. According to Peirce's pragmatic model, semiosis is a triadic, time-bound, context-sensitive, interpreter-dependent, materially extended dynamic process. (...) Semiosis involves inter-relatedness and inter-action between signs, their objects, acts and events in the world, and the semiotic agents who are in the process of making and taking them. (shrink)

Few views are as widely held as the Standard View of Identity. Here I am concerned with minority views that depart from the standard account. First, I attempt to illuminate such views and the debates concerning them by identifying the principles of identity at issue, articulating some of the assumptions underlying the debates, and presenting some of the evidence used against the Standard View of Identity. Second, I enter two of these debates myself. I first defend two Non-Standard Views of (...) Identity from the charge that they violate a principle of identity, namely the Transitivity of Identity. I then present an overlooked consequence of another Non-Standard View of Identity that challenges the view on one of its own methodological principles. Third, I draw on recent work in ontological and parthood pluralism to show how one might be led to think that there is more than one way of being identical. That is, I show how one might be an identity pluralist. (shrink)

Biosemiotics is a growing fi eld that investigates semiotic processes in the living realm in an attempt to combine the fi ndings of the biological sciences and semiotics. Semiotic processes are more or less what biologists have typically referred to as “ signals, ” “ codes, ”and “ information processing ”in biosystems, but these processes are here understood under the more general notion of semiosis, that is, the production, action, and interpretation of signs. Thus, biosemiotics can be seen as biology (...) interpreted as a study of living sign systems — which also means that semiosis or sign process can be seen as the very nature of life itself. In other words, biosemiotics is a field of research investigating semiotic processes (meaning, signification, communication, and habit formation in living systems) and the physicochemical preconditions for sign action and interpretation. -/- (...).

Há alguns anos atrás, algumas pessoas acreditavam que a tese de que a existência não é um predicado, uma tese defendida por autoridades como Gottlob Frege e Bertrand Russell, era um dos traços distintivos da chamada filosofia analítica. Que uma tal crença é afinal falsa pode ser tomado como mais um sinal da vitalidade e do anti-dogmatismo que caracterizam em geral a tradição analítica; e o mesmo se aplica a quaisquer outras crenças do género, que comprometam esta tradição com teses (...) filosóficas substantivas. O meu propósito neste ensaio é duplo. Por um lado, descrevo o estado actual da questão relativamente ao venerável tópico da existência, caracterizando e examinando as principais teorias disponíveis. Por outro, argumento a favor de um ponto de vista específico sobre o tópico. Esse ponto de vista consiste na conjunção das seguintes três teses: (F) Não há objectos não-existentes; (H*) A existência é um predicado; e (H**) As afirmações de existência não são uniformes quanto à forma lógica, tendo por vezes a forma de quantificações existenciais e por vezes a forma de predicações monádicas de primeira ordem.

Este ensaio consiste num exame crítico da estrutura e do valor de um conjunto diverso de argumentos por regressão ao infinito que têm sido objecto de discussão recorrente na metafísica contemporânea. O seminal livro de David Armstrong Nominalism and Realism (Armstrong 1978) contém uma das mais compreensivas discussões de argumentos regressivos em metafísica, os quais variam entre argumentos que foram de facto avançados ao longo da história da disciplina (como o Argumento do Terceiro Homem, de Platão) e argumentos construídos de (...) novo por Armstrong para fins de exame crítico. Os argumentos regressivos discutidos por Armstrong têm como alvo uma grande variedade de teorias metafísicas acerca da semelhança e da predicação, entre as quais se contam o nominalismo de predicados, o nominalismo de conceitos, o nominalismo de classes, o nominalismo de semelhança e o realismo metafísico.

Neste ensaio, discutem-se cinco questões acerca da existência: 1. É a existência representável em termos de quantificação? 2. É a existência um predicado" real", de primeira ordem? 3. É existir o mesmo que ser? 4. Existe tudo? 5. Qual é a forma lógica de afirmações de existência? São introduzidas e examinadas algumas das mais salientes posições acerca destas questões, em especial a concepção Frege-Russell da existência e diversas concepções recentes neo-Meinongianas. Defendemos as seguintes três teses acerca daquilo que deve ser (...) um bom predicado de existência:(a) um predicado puramente lógico e parcialmente definível em termos do quantificador existencial;(b) invariavelmente um predicado de primeira ordem (dadas certas suposições de partida acerca do universo do discurso);(c) um predicado universal, verdadeiro de tudo e falso de nada.

Certain problems with standard two-dimensional semantics are addressed and cases in which these problems arise explored. In such cases the primary intension cannot be univocally mapped in one and only one indexical world, thus standard two-dimensional semantics cannot efficiently address the problems presented. Subsequently, a modified model is presented which leads these problems to be averted in the replicated cases. This modified model admits primary intensions that are not univocally mapped. The conclusion discusses the advantages and disadvantages of the modified (...) model and analyzes its possible consequences for the philosophy of mind. (shrink)

Qual o lugar da filosofia nos dias atuais? Diante das inúmeras respostas possíveis a esta questão, nos debruçaremos em alguns tópicos que podemos inserir na chamada Ética Informacional, um ramo de investigação filosófico-interdisciplinar relativamente recente que discute problemas oriundos da relação ser humano/tecnologias digitais. Temas como privacidade informacional, arrogância epistêmica e divisão digital serão discutidos e relacionados, com o intuito de ilustrar o papel da filosofia na compreensão da complexidade inerente às dinâmicas sociais no contexto da sociedade da informação. Argumentaremos (...) que pensar o mundo contemporâneo a partir do viés da ética informacional se faz cada dia mais imprescindível para que possamos entrar em sintonia com as rápidas mudanças que a revolução informacional impõe à vida em sociedade e não sermos levados pelas enxurradas informacionais que presenciamos diariamente.

Queremos neste ensaio caracterizar de modo introdutório o essencial do legado de Gottlob Frege para a Filosofia da Linguagem contemporânea, identificando e caracterizando os traços distintivos mais genéricos de uma teoria do significado (ou conteúdo semântico) inspirada nas suas ideias seminais e contrastando-a com outras concepções actuais influentes acerca do significado, em especial as posições sobre o conteúdo singular (conteúdo expresso por nomes próprios e outros termos singulares) remotamente inspiradas em ideias de John Stuart Mill.

These three volumes, entitled Essays On Values, bring together fortyone recent articles by researchers at the Nova Institute of Philosophy (IFILNOVA). They are a small sample of everything that, in the last four years, the Institute’s researchers have published, in English, in indexed journals and collections of essays with peer review. As a whole, they reflect very well the research work that is done at IFILNOVA. Section I. of Volume 1 gathers six articles that deal directly with the question “what (...) are values?”, the question that guides all the work of the institute’s different laboratories and research groups. The first article, by Susana Cadilha and Vítor Guerreiro, results from work developed in the Laboratory of Ethics and Political Philosophy (EPLab); the second, by João Constâncio, from the Lisbon Nietzsche Group; the third, by Alexandra Dias Fortes, from the Lisbon Wittgenstein Group; the third and fifth, by Nuno Fonseca, and Maria Filomena Molder, from the Aesthetics and Philosophy of Art Group of the Laboratory of Culture and Value (CultureLab); the last, by Erich H. Rast, from the Philosophy of Language and Argumentation Theory Group and the Lisbon Mind, Cognition & Knowledge Group of the Laboratory of Argumentation, Cognition, and Language (ArgLab). Section II. brings together three articles by members of the Lisbon Nietzsche Group. Since 2010, the Lisbon Nietzsche Group has completed several funded projects, and has established itself as a leading international research group on Nietzsche’s thought. The three articles demonstrate the crucial importance of the question of values in Nietzsche’s work, always thought from the perspective of the possibility of a “transvaluation of all values”. Maria João Mayer Branco’s article focuses on the value of introspection, and how Nietzsche anticipates Wittgenstein’s “expressivist” view of the “the Peculiar Grammar of the Word ‘I’” and the impossibility of private languages. Marta Faustino’s article considers the theme of affirmation and the value of life through the interpretation of Nietzsche’s reflection on truthfulness, intellectual honesty and courage in the light of Michel Foucault’s work on parrhesia. Pietro Gori’s article studies how Nietzsche creates a new anthropological ideal based on his enquiry into the values of the “good European”. The area of Wittgenstein studies has had a strong influence on the institute since the time when it was a philosophy of language institute. The Wittgensteinian distinction between facts and values was decisive in defining the question of values as the central issue of IFILNOVA’s research project, replacing the focus on philosophy of language. More recently, the focus of research at the Lisbon Wittgenstein Group has been on epistemic values, in particular in their connection with the question of religious belief. In Section III., Nuno Venturinha’s article examines, in the light of an epistemological standpoint, the way Wittgenstein thinks about the possibility of translation. Robert Vinten’s article argues that Wittgenstein’s thought contains elements for a critique of the concept of justice and of the liberal political visions of both Richard Rorty and Chantal Mouffe, despite the fact that both have drawn inspiration from Wittgenstein. Benedetta Zavatta’s article questions the value of mythology by thinking of it as a disease of language – not only in Wittgenstein, but also in a whole philosophical tradition that preceded him. The existence of a research group in ancient philosophy is a recent but very promising development in the life of IFILNOVA. Section IV. includes two articles by members of the group. Paulo Alexandre Lima’s article considers the critique of misology and the value of discourse in Plato’s Phaedo. Hélder Telo’s article examines the pedagogical and protreptic value of imperfection in Plato’s work. (shrink)

The suggestion of something akin to a ‘relativist solution to the Mind-Body problem’ has recently been held by some scientists and philosophers; either explicitly (Galadí, 2023; Lahav & Neemeh, 2022; Ludwig, 2015) or in more implicit terms (Solms, 2018; Velmans, 2002, 2008). In this paper I provide an argument in favor of a relativist approach to the Mind-Body problem, more specifically, an argument for ‘1st/3rd person relativism’, the claim that ‘The truth value of some sentences or propositions is relative to (...) 1st and 3rd person perspectives’. The argument for 1st/3rd person relativism is close to a forma proof. It is shown that, just by assuming the 1st/3rd person distinction itself and using first order logic and set theory, ‘1st/3rd person relativism’ follows as a theorem. Some consequences of ‘1st/3rd person relativism’ to the Mind-Body Problem are evaluated. It is shown that ‘1st/3rd person relativism’ predicts the existence of an (apparent) Explanatory Gap; explains why the Explanatory Gap is just apparent (and the origins of such illusion); dissolves the Hard-Problem; provides a possible solution the problem of Mental Causation; explains why Mental Causation looks like a problem in the first place and accurately predicts the actual empirically found correlation and covariation between conscious experiences and brain states. This explanatory power of ‘1st/3rd person relativism’ is particularly impressive since it was not designed as a possible solution to the Mind-Body problem in the first place. (shrink)

Queremos neste ensaio introduzir um esboço de uma semântica simples e adequada para uma classe importante de predicações singulares de inexistência, ou frases existenciais singulares negativas. Frases deste género, como “Sócrates (já) não existe” e “O pássaro Dódó não existe”, são usualmente tidas como de algum modo paradoxais e semanticamente problemáticas. O modelo semântico que vamos delinear para tais frases, que desejavelmente se caracteriza pela simplicidade e pela economia, depende no entanto de duas importantes e substantivas suposições de partida, e, (...) mais crucialmente, de uma tese semântica de alguma maneira controversa acerca da referência singular. Trata-se da tese da rigidez obstinada, a tese de que nomes próprios e outros termos irredutivelmente singulares – tais como indexicais, demonstrativos e termos para categorias naturais – são designadores, não apenas rígidos, mas obstinadamente rígidos, dos objectos que de facto designam.

This paper discusses two notational variance views with respect to indexical singular reference and content: the view that certain forms of Millianism are at bottom notational variants of a Fregean theory of reference, the Fregean Notational Variance Claim; and the view that certain forms of Fregeanism are at bottom notational variants of a direct reference theory, the Millian Notational Variance Claim. While the former claim rests on the supposition that a direct reference theory could be easily turned into a particular (...) version of a neo-Fregean one by showing that it is bound to acknowledge certain senselike entities, the latter claim is based upon the supposition that a neo-Fregean theory could be easily turned into a particular version of a Millian one by showing that De Re senses are theoretically superfluous and hence eliminable. The question how many accounts of singular reference and content are we confronted with here — Two different (and mutually antagonistic) theories? Or just two versions of what is in essence the same theory? — is surely of importance to anyone interested in the topic. And this question should be answered by means of a careful assessment of the soundness of each of the above claims. Before trying to adjudicate between the two accounts, one would naturally want to know whether or not there are indeed two substantially disparate accounts. Grosso modo, if the Fregean Claim were sound then we would have a single general conception of singular reference to deal with, viz. Fregeanism; likewise, if the Millian Claim were sound we would be facing a single general conception of singular reference, viz. Millianism. My view is that both the Fregean Notational Variance Claim and its Millian counterpart are wrong, though naturally on different grounds. I have argued elsewhere that the Fregean Notational Variance Claim - considered in its application to the semantics of propositional-attitude reports involving proper names — is unsound. I intend tosupplement in this paper such a result by trying to show that the Millian Claim - taken in its application to the semantics of indexical expressions — should also be rated as incorrect. I focus on a certain set of arguments for the Millian Claim, arguments which I take as adequately representing the general outlook of the Millian theorist with respect to neo-Fregeanism about indexicals and which involve issues about the cognitive significance of sentences containing indexical terms. (shrink)

The aim of this paper is to survey a number of features which are constitutive of the Millian account of attitude-ascription and which I take to be irremediably defective. The features in question, some of which have not been fully appreciated, relate mainly to the failure of that account to accommodate certain fundamental aspects of our ordinary practise of attitude attribution. I take it that one’s definitive method of assessment of a given semantical theory consists in checking out whether or (...) not the theory is able to accommodate our pre-theoretical linguistic intuitions; to use Keith Donnellan’s phrase, such intuitions are the bottom line in philosophical argumentation about language. And I argue that the Millian appeal to modes of presentation taken both as semantically irrelevant and external to the singular contents believed, known, etc., as well as the associated pragmatic strategy employed to discard our ground-floor judgements, are insufficient to palliate the manifest implausibility of a number of Millian descriptions of our attitudes, especially descriptions of our second-order attitudes.

Os tópicos e problemas filosóficos discutidos no volume são de natureza bastante variada: a natureza da complexidade computacional no processamento de uma língua natural; a relação entre o significado linguístico e o sentido Fregeano; as conexões entre a a agência e o poder; o conteúdo semântico da ficção; a explicação dos impasses éticos; a natureza dos argumentos cépticos; as conexões entre as dissociações cognitivas e o carácter modular da mente; a relação entre a referência e o significado. Estes tópicos deixam-se (...) subsumir num tema mais geral, o tema das ligações múltiplas entre a cognição e o conteúdo, mental ou linguístico. O tópico do conteúdo, a questão de determinar como é que muitas das nossas elocuções e muitos dos nossos estados mentais são dotados de conteúdo, representam algo (correcta ou incorrectamente), e o tópico da cognição, a investigação da natureza e dos mecanismos envolvidos na cognição humana, no processamento de informação tipicamente proveniente do exterior, são inegavelmente tópicos centrais da investigação filosófica, presente ou passada.Dado o carácter inclusivo e pluridisciplinar dos tópicos cobertos, não é surpreendente que os ramos da Filosofia representados no presente volume sejam igualmente diversificados: a Filosofia Moral, a Filosofia da Linguagem, a Teoria do Conhecimento, a Filosofia da Mente, os Fundamentos da Ciência Cognitiva. E também não é surpreendente que nele também estejam representados outros ramos do conhecimento cuja relevância para o estudo do conteúdo e da cognição é conspícua: a Psicologia Cognitiva; a Linguística Computacional e a Inteligência Artificial. Os autores dos ensaios são de proveniências diversas. De um lado, há um conjunto de especialistas nacionais a trabalhar na tradição analítica em Filosofia, como João Branquinho, ou a trabalhar em algumas áreas filosoficamente importantes da Ciência Cognitiva, como António Branco (Processamento da Língua Natural), José Frederico Marques (Psicologia Cognitiva) e Helder Coelho (Inteligência Artificial). Do outro lado, há um conjunto de especialistas estrangeiros de elevada reputação internacional: Allan Gibbard, da Universidade de Michigan, autor de livros influentes na área da Ética e Filosofia Moral; Stephen Schiffer, da New York University, uma das principais figuras actuais da Filosofia da Linguagem e da Semântica Geral; Paolo Leonardi, da Universidade de Bolonha, um especialista nas áreas da Filosofia da Linguagem e Filosofia da Comunicação; e Manuel García-Carpintero, da Universidade de Barcelona, um dos grandes vultos da Filosofia Analítica praticada em Espanha e na Europa Continental.

Neste artigo discutimos a passagem da “virada naturalista” à “virada informacional” na Filosofia, ao argumentar que o processo de desconstrução da metafísica da subjetividade ocorrido na primeira virada teria contribuído para a emergência da segunda. Evidenciamos, com isso, como a concepção cartesiana de ser humano como único possuidor de alma e medida de todas as coisas passou para um cenário no qual ele é concebido como apenas mais uma animal dentre outros (pela influência do darwinismo) e, posteriormente, como a exclusividade (...) e superioridade do ser humano foi novamente afetada com o desenvolvimento de “modelos mecânicos da mente”. Por fim, justificamos a relevância da análise da subjetividade também pela ótica da Ética Informacional, tendo em vista a crescente incorporação das tecnologias no cotidiano dos indivíduos, bem como as características subjacentes a tais tecnologias.

Este trabalho apresenta uma discussão que tem como objetivo principal propor um novo risco ao contorno da noção de intericonicidade que aparece em Courtine, precisamente, em 2003. Aí encontramos uma abertura que nos permite traçar outras curvaturas em sua noção. É justamente por este interstício que vamos propor a inclusão de dois elementos que, a nosso ver, estão na ordem da constituição das imagens: as utopias e heterotopias, conforme discussões iniciadas anteriormente por Araújo (2014a, 2014b). Para tanto, tomamos como (...) pano de fundo as imagens em movimento de duas produções francesas de horror e as imagens fotográficas da prisão de Abou Ghraib que serão analisadas à luz da discussão realizada por Foucault em Le corps utopique, les heterotopies e em Outros Espaços, juntamente com as discussões de Courtine e de Milanez acerca da intericonicidade (cf. COURTINE, 2005; 2011; 2013; MILANEZ, 2011a; 2011b; 2013a, 2013b). Os Elementos de Semiologia e A escrita do acontecimento de Barthes também fazem parte da discussão, já que este autor aparece desde cedo no trabalho de Courtine, precisamente, quando buscava apresentar a noção de intericonicidade.

This paper discusses some relations between the notion of Fregean sense and the notion of linguistic meaning. It argues that these notions come apart from one another even in the case of non-indexical expressions. In particular, synonymous non-indexical expressions may be assigned different Fregean senses with respect to certain contexts of use.

Peirce's pragmatic notion of semiosis can be described in terms of a multi-level system of constraints involving chance, efficient, formal and final causation. According to the model proposed here, law-like regularities, which work as boundary conditions or organizational principles, have a downward effect on the spatiotemporal distribution of lower-level semiotic items. We treat this downward determinative influence as a propensity relation: if some lower-level entities a,b,c,-n are under the influence of a general organizational principle, W, they will show a tendency (...) to behave in certain specific ways, and, thus, to instantiate a set of specific processes. Our goal in this paper is to examine the role of downward determination in semiotic systems, conceived as multi-level hierarchical systems. (shrink)

We will make a new approach for an effect known as “Dark Energy” by an effect on gravitational field. In an accelerated rocket, the dimensions of space towards movement due to ‘Lorentz Contraction’ are on continuous reduction. Using the equivalence principle, we presume that in the gravitational field, the same thing would happen. In this implicates in ‘dark energy effect’. The calculi show that in a 7%-contraction for each billion years would explain our observation of galaxies in accelerated separation.

The aim of the paper is to sketch a principle of individuation that is intended to serve the Fregean notion of a proposition, a notion I take for granted. A salient feature of Fregean propositions, i.e. complexes of modes of presentation of objects, is that they are fine-grained items, so fine-grained that even synonymous sentences might express different Fregean propositions. My starting point is the principle labelled by Gareth Evans the Intuitive Criterion of Difference for Thoughts, which states that it (...) is impossible coherently to take different mental attitudes to the same proposition. As a logical truth, this is a synchronic principle, the application of which is restricted to attitudes held at a single time. I argue that such a restriction might be reasonably lifted and, on the basis of an adequate notion of attitude-retention, I propose an admissible diachronic extension of the principle. (shrink)

Este trabalho trata do conceito Exu Diaspórico, o qual foi forjado para lidar com as pesquisas empíricas situadas dentro do quadro teórico da vaga decolonial. Sua concepção está ligada às tradições iorubanas diaspóricas nessa parte do Atlântico Sul onde emergiram outros sistemas resultantes, quer seja de fragmentos e vestígios de narrativas em gestos de memória e resistência, quer seja da tradução realizada pelo outro, muitas vezes, por meio de um processo de carnavalização cultural, que, por sua vez, se deu pela (...) convivência com os bantu, com os povos autóctones e com o colonizador europeu. Este conceito se articula com o conceito de língua-linguagem como encruzilhada apresentado por Araújo (2021a), mas pode ser tomado, ainda, de forma independente. Portanto, trata-se de uma discussão conceitual que visa contribuir com as reflexões e pesquisas decoloniais. O conceito também está a cargo de noções como negritude e Baianidade. Contudo, ele aparece para reunir todas as representações de Exu que resultaram da diáspora negra em meio a um processo de carnavalização das tradições iorubanas em contato com outras culturas e cosmologias.

This paper introduces new logical systems which axiomatize a formal representation of inconsistency (here taken to be equivalent to contradictoriness) in classical logic. We start from an intuitive semantical account of inconsistent data, fixing some basic requirements, and provide two distinct sound and complete axiomatics for such semantics, LFI1 and LFI2, as well as their first-order extensions, LFI1* and LFI2*, depending on which additional requirements are considered. These formal systems are examples of what we dub Logics of Formal Inconsistency (LFI) (...) and form part of a much larger family of similar logics. We also show that there are translations from classical and paraconsistent first-order logics into LFI1* and LFI2*, and back. Hence, despite their status as subsystems of classical logic, LFI1* and LFI2* can codify any classical or paraconsistent reasoning. (shrink)

Este artigo tem por objetivo descrever e comparar as propostas da política de reconhecimento desenvolvidas por Axel Honneth, na obra Luta por reconhecimento, e por Charles Taylor, na obra Argumentos filosóficos. Ambos os pensadores buscam em Hegel uma referência teórica para renovar suas teorias. Em Honneth, a noção de reconhecimento está fortemente ancorada na intersubjetividade dos indivíduos, decorrente de uma luta por reconhecimento: o desrespeito a qualquer uma das formas de reconhecimento pleno – o amor, o direito e a solidariedade (...) – gera demandas sociais de reconhecimento e, consequentemente, a luta pelo mesmo. Em Taylor, o reconhecimento pressupõe uma noção ontológica de bem, prefigurado na linguagem, tradição, valores e costumes. Ambos os autores mantêm um vínculo forte com a ideia hegeliana da intersubjetividade como instância fundamental na formação das identidades, enquanto base coletiva dos movimentos sociais. (shrink)

These three volumes, entitled Essays On Values, bring together fortyone recent articles by researchers at the Nova Institute of Philosophy (IFILNOVA). They are a small sample of everything that, in the last four years, the Institute’s researchers have published, in English, in indexed journals and collections of essays with peer review. As a whole, they reflect very well the research work that is done at IFILNOVA. Section I. of Volume 1 gathers six articles that deal directly with the question “what (...) are values?”, the question that guides all the work of the institute’s different laboratories and research groups. The first article, by Susana Cadilha and Vítor Guerreiro, results from work developed in the Laboratory of Ethics and Political Philosophy (EPLab); the second, by João Constâncio, from the Lisbon Nietzsche Group; the third, by Alexandra Dias Fortes, from the Lisbon Wittgenstein Group; the third and fifth, by Nuno Fonseca, and Maria Filomena Molder, from the Aesthetics and Philosophy of Art Group of the Laboratory of Culture and Value (CultureLab); the last, by Erich H. Rast, from the Philosophy of Language and Argumentation Theory Group and the Lisbon Mind, Cognition & Knowledge Group of the Laboratory of Argumentation, Cognition, and Language (ArgLab). Section II. brings together three articles by members of the Lisbon Nietzsche Group. Since 2010, the Lisbon Nietzsche Group has completed several funded projects, and has established itself as a leading international research group on Nietzsche’s thought. The three articles demonstrate the crucial importance of the question of values in Nietzsche’s work, always thought from the perspective of the possibility of a “transvaluation of all values”. Maria João Mayer Branco’s article focuses on the value of introspection, and how Nietzsche anticipates Wittgenstein’s “expressivist” view of the “the Peculiar Grammar of the Word ‘I’” and the impossibility of private languages. Marta Faustino’s article considers the theme of affirmation and the value of life through the interpretation of Nietzsche’s reflection on truthfulness, intellectual honesty and courage in the light of Michel Foucault’s work on parrhesia. Pietro Gori’s article studies how Nietzsche creates a new anthropological ideal based on his enquiry into the values of the “good European”. The area of Wittgenstein studies has had a strong influence on the institute since the time when it was a philosophy of language institute. The Wittgensteinian distinction between facts and values was decisive in defining the question of values as the central issue of IFILNOVA’s research project, replacing the focus on philosophy of language. More recently, the focus of research at the Lisbon Wittgenstein Group has been on epistemic values, in particular in their connection with the question of religious belief. In Section III., Nuno Venturinha’s article examines, in the light of an epistemological standpoint, the way Wittgenstein thinks about the possibility of translation. Robert Vinten’s article argues that Wittgenstein’s thought contains elements for a critique of the concept of justice and of the liberal political visions of both Richard Rorty and Chantal Mouffe, despite the fact that both have drawn inspiration from Wittgenstein. Benedetta Zavatta’s article questions the value of mythology by thinking of it as a disease of language – not only in Wittgenstein, but also in a whole philosophical tradition that preceded him. The existence of a research group in ancient philosophy is a recent but very promising development in the life of IFILNOVA. Section IV. includes two articles by members of the group. Paulo Alexandre Lima’s article considers the critique of misology and the value of discourse in Plato’s Phaedo. Hélder Telo’s article examines the pedagogical and protreptic value of imperfection in Plato’s work. (shrink)
