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.

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.

Esta enciclopédia abrange, de uma forma introdutória mas desejavelmente rigorosa, uma diversidade de conceitos, temas, problemas, argumentos e teorias localizados numa área relativamente recente de estudos, os quais tem sido habitual qualificar como «estudos lógico-filosóficos». De uma forma apropriadamente genérica, e apesar de o território teórico abrangido ser extenso e de contornos por vezes difusos, podemos dizer que na área se investiga um conjunto de questões fundamentais acerca da natureza da linguagem, da mente, da cognição e do raciocínio humanos, bem (...) como questões acerca das conexões destes com a realidade não mental e extralinguística. A razão daquela qualificação é a seguinte: por um lado, a investigação em questão é qualificada como filosófica em virtude do elevado grau de generalidade e abstracção das questões examinadas (entre outras coisas); por outro, a investigação é qualificada como lógica em virtude de ser uma investigação logicamente disciplinada, no sentido de nela se fazer um uso intenso de conceitos, técnicas e métodos provenientes da disciplina de lógica. O agregado de tópicos que constitui a área de estudos lógico-filosóficos é já visível, pelo menos em parte, no Tractatus Logico-Philosophicus de Ludwig Wittgenstein, uma obra publicada em 1921. E uma boa maneira de ter uma ideia sinóptica do território disciplinar abrangido por esta enciclopédia, ou pelo menos de uma porção substancial dele, é extrair do Tractatus uma lista dos tópicos mais salientes aí discutidos; a lista incluirá certamente tópicos do seguinte género, muitos dos quais se podem encontrar ao longo desta enciclopédia: factos e estados de coisas; objectos; representação; crenças e estados mentais; pensamentos; a proposição; nomes próprios; valores de verdade e bivalência; quantificação; funções de verdade; verdade lógica; identidade; tautologia; o raciocínio matemático; a natureza da inferência; o cepticismo e o solipsismo; a indução; as constantes lógicas; a negação; a forma lógica; as leis da ciência; o número.

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)

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.

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)

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)

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. -/- (...).

Dance, Music and Dramaturgy: collaboration plan and dramaturgical apparatus – The unfolding of the concept of dramaturgy and the problematics of contemporary choreography are, today, a vast and diverse field of research, bearing numerous disclosures that lead to their reciprocal implication. Apart from that, dance and music share significant complementary ties allowing for the consideration of a common compositional inquiry. Reflecting on the compositional processes of dance and music, this article cross-examines the collaboration between choreographers and composers, integrating the incidence (...) of dramaturgy in the strategies of choreographic and musical composition.

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.

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.

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.

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.

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.

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)

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.

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. (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.

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.

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.

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.

Terms loaded with informational connotations are often employed to refer to genes and their dynamics. Indeed, genes are usually perceived by biologists as basically ‘the carriers of hereditary information.’ Nevertheless, a number of researchers consider such talk as inadequate and ‘just metaphorical,’ thus expressing a skepticism about the use of the term ‘information’ and its derivatives in biology as a natural science. First, because the meaning of that term in biology is not as precise as it is, for instance, in (...) the mathematical theory of communication. Second, because it seems to refer to a purported semantic property of genes without theoretically clarifying if any genuinely intrinsic semantics is involved. Biosemiotics, a field that attempts to analyze biological systems as semiotic systems, makes it possible to advance in the understanding of the concept of information in biology. From the perspective of Peircean biosemiotics, we develop here an account of genes as signs, including a detailed analysis of two fundamental processes in the genetic information system (transcription and protein synthesis) that have not been made so far in this field of research. Furthermore, we propose here an account of information based on Peircean semiotics and apply it to our analysis of transcription and protein synthesis. (shrink)

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)

El Naturalismo Trascendental del Ultimo Wittgenstein The present article considers an internal tension in Wittgenstein's late philosophy. In what I call his 'naturalism', Wittgenstein circumscribes philosophical reflection to natural objects, to «making natural history». In his 'transcendentalism' he focuses on the «possibility of phenomena» and distinguishes philosophical method from the method of the natural sciences. I show that his 'transcendentalism' is present in his discussion of rules and prívate language, arguing for an interpretation in terms of a kantian type of (...) transcendental synthesis. But far from contradicting his 'naturalism', both tendencies are inseparable and essential to the main purpose of his Philosophical Investigations. (shrink)

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)

In his 1903 Syllabus, Charles S. Peirce makes a distinction between icons and iconic signs, or hypoicons, and briefly introduces a division of the latter into images, diagrams, and metaphors. Peirce scholars have tried to make better sense of those concepts by understanding iconic signs in the context of the ten classes of signs described in the same Syllabus. We will argue, however, that the three kinds of hypoicons can better be understood in the context of Peirce's sixty-six classes of (...) signs. We analyze examples of hypoicons taken from the field of information design, describing them in the framework of the sixty-six classes, and discuss the consequences of those descriptions to the debate about the order of determination of the 10 trichotomies that form those classes.

Jean-Jacques Rousseau was undoubtedly the first to investigate the ethical role of art in modern philosophical thought. However, his position was decidedly eccentric amidst the backdrop of the Enlightenment. According to Rousseau, Art was responsible for the destruction of virtue, but is responsible now for concocting a moral veneer. Art’s function is to construct this “moral veneer” that brings a stop to man’s turpitudes or, at least, reduces their occurrence. Art’s ethical benefit is not that it leads man to do (...) good. Rather, the artistic simulacrum prevents the most hideous crimes from occurring. This paper investigates the ethical role of art in Rousseau's First Discourse and in the preface to his play Narcissus or the Self-Admirer. (shrink)

O presente trabalho visa apresentar a solução dada por Santo Agostinho ao problema do mal, aliado à aparente contraditoriedade entre a presciência de Deus e a liberdade humana.

Intersemiotic translation (IT) was defined by Roman Jakobson (The Translation Studies Reader, Routledge, London, p. 114, 2000) as “transmutation of signs”—“an interpretation of verbal signs by means of signs of nonverbal sign systems.” Despite its theoretical relevance, and in spite of the frequency in which it is practiced, the phenomenon remains virtually unexplored in terms of conceptual modeling, especially from a semiotic perspective. Our approach is based on two premises: (i) IT is fundamentally a semiotic operation process (semiosis) and (ii) (...) IT is a deeply iconic-dependent process. We exemplify our approach by means of literature to dance IT and we explore some implications for the development of a general model of IT. (shrink)

This article presents some results of a research on computational strategies for the visualization of sign classification structures and sign processes. The focus of this research is the various classifications of signs described by Peirce. Two models are presented. One of them concerns specifically the 10-fold classification as described in the 1903 Syllabus (MS 540, EP 2: 289–299), while the other deals with the deep structure of Peirce’s various trichotomic classifications. The first is 10cubes, an interactive 3-D model of Peirce’s (...) 10-fold classification, as described in the Syllabus. The second is 3N3, a computer program that builds equivalent diagrams for any n-trichotomic classification of signs. We are specially interested in how a graphic design methodology, associated with computer graphic resources and techniques, can contribute to the construction of interactive models that serve as tools for the investigation of C. S. Peirce’s theory of signs. (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)

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).

We explore Peirce’s pragmatic conception of sign action, as a distributed and emergent view of cognition and exemplify with the emergence of classical ballet. In our approach, semiosis is a temporally distributed process in which a regular tendency towards certain future outcomes emerges out of a history of sign actions. Semiosis self-organizes in time, in a process that continuously entails the production of more signs. Emergence is a ubiquitous condition in this process: the translation of signs into signs cannot be (...) inferred from the properties of the components of a semiotic triad alone, but has to take into account a complex interaction between a micro-semiotic and macro-semiotic level of description. This interaction can be understood as an interplay of potentialities and tendencies, or upward constitutive determinative relations and downward selective determinative relations. According to this view, emergence is a central defining condition of processes of meaning. Ballet is a sign in action. The emergence of classical ballet is a self-regulatory process, in which a system of different kinds of cognitive artifacts (musical, bodily/motor, spatial/architectonic) and agents obtained a stable semiotic relation throughout many phases of development between the 16th and the 19th Century. One case is the development of the verticality of dance in classical ballet as a semiotic relation connecting proscenium arch stages, dancing bodies, and audiences. This development is micro-semiotically determined by the spatial constraints of the proscenium arch stage, and macro-semiotically determined by a historical construction of the dancing body as a sign within a network of semiotic chains, such as the intersemiotic regulation of body of the dancer by principles coming from painting. This is not only the emergence of actual meaning, but also the emergence of an open-ended field of potential and general meanings, an autonomous tendency of development. To say that ballet, as sign action, emerges, is to say that cognitive artifacts such as dancer’s bodies, stages and audience’s point of view, musical compositions, costumes, all sorts of supporting institutions, etc, constitute a niche for sign action, interacting according to tendencies of development that didn’t exist before.
