En este libro, John Perry elabora una teoria "reflexivo-referencial" de los indexicos, los demostrativos y los nombres propios. La Filosofia del Lenguaje del siglo veinte se vio condicionada por dos tradiciones enfrentadas en torno a esos temas: el descriptivismo y el referencialismo. Los textos referecialistas clasicos de, entre otros, Saul Kripke, Keith Donnellan y David Kaplan son de los anos 70. Curiosamente, parece que ya habian sido refutados casi un siglo antes por los problemas de co-referencia y no-referencia planteados por (...) Frege y Russell. La teoria de Perry, que toma prestadas ideas de ambas tradiciones asi como de Burks y Reichenbach, situa el origen de los problemas en la atencion exclusiva a un tipo de contenido: el contenido llamado referencial o completamente incremental. La tradicion referencialista se caracteriza por la tesis de que los indexicos proporcionan un contenido que involucra a individuos pero no a sus condiciones de identificacion. La tradicion descriptivista se caracteriza por la tesis de que el contenido referencial no explica todas las condiciones de identificacion que ofrecen los nombres y los indexicos. Perry nos propone una familia coherente y estructurada de contenidos -desde contenidos reflexivos que imponen condiciones a la proferencia hasta contenidos completamente incrementales que ponen condiciones solo a los objetos de la referencia-que sirve para reconciliar lo mejor de ambas tradiciones.

Nuestro objetivo es analizar críticamente el enfoque de la noción de modelo de Alfred Tarski que Patrick Suppes integra en su concepción semanticista de las teorías científicas. En efecto, mostraremos cómo esta noción se configura en Suppes (1969; 1970) desde una revisión formal de la noción de modelo en Tarski (1936), focalizando nuestro análisis en tres ejes principales: i) una crítica a la perspectiva estática del semanticismo; ii) un análisis de las condiciones restrictivas y el lenguaje para la axiomatización de (...) teorías; y iii) la revisión de las nociones de ‘sistema axiomático’, ‘sistema formal’ y ‘método axiomático’.

O objetivo do texto é abordar a temática dos meios de comunicação como instrumento de poder à luz da indústria cultural conforme Theodor Adorno. Busca-se responder à seguinte questão: como a indústria cultural reproduz as relações de poder no capitalismo contemporâneo? Para a consecução de tal objetivo, o texto apresenta as seguintes etapas: uma breve contextualização histórica e teórica da Teoria Crítica - vertente filosófica à qual Adorno e outros autores se filiaram – a definição da indústria cultural conforme Adorno (...) em seus principais argumentos, os efeitos da indústria cultural e do capitalismo organizado, a postura crítica frente ao contexto referido e a nova postura de Adorno nos anos 50 e 60 frente aos meios de comunicação. A principal tese do artigo leva ao entendimento de que a indústria cultural incorpora toda uma racionalidade de dominação e disciplina da vida social e reprodução da ordem capitalista vigente, acabando com as contradições no âmbito das manifestações artísticas na medida em que somente o lucro é visado.

Resumen: El artículo estudia los aspectos fundamentales de la crítica de Dussel al modelo formal de hegemonía desarrollado por Laclau. En este contexto, se presenta la propuesta de una hegemonía popular ligada a la centralidad de la reproducción de la vida como criterio normativo de la política y se denuncia el decisionismo abstracto de la teoría populista laclauniana. Pero también en este texto se ofrece, siguiendo la lectura de Castro-Gómez, una crítica de las tesis de Dussel desde un punto de (...) vista postfundacionalista, lo que supone cuestionar la idea misma de un universal incondicionado. Finalmente, concluimos exponiendo una crítica a algunas de las coordenadas teóricas compartidas por ambos autores, identificando las limitaciones del concepto mismo de hegemonía.: This article studies the fundamental aspects of Dussel’s critique of the formal model of hegemony developed by Laclau. In this context, a concept of popular hegemony tied to the centrality of the reproduction of life as a normative criterion in politics is proposed, as well as an argument against the abstract decisionism of the populist theory of Laclau. The text also offers -as suggested by Castro-Gomez’s reading- a critique of Dussel’s ideas from a post-foundationalist perspective, which leads to questioning the very idea of an unconditional universal. Finally, we conclude by positing a critique of some of the theoretical viewpoints shared by both authors, identifying the limitations of the very concept of hegemony. (shrink)

El presente texto se interroga sobre los efectos performativos del himno de Chile en cuanto éste designa al país en la forma de una "copia feliz del Edén". A partir de ahí, se pregunta ¿cómo podría una copia afirmarse en la originalidad de una soberanía? Para solucionar la distancia entre copia y original y, por tanto, dar lugar al funcionamiento de la soberanía, el himno designa a esa copia como "feliz". El término "feliz" se constituye, así, en el operador que (...) vendría tanto a apuntalar a la constitución de una soberanía como a revelar el límite de su imposibilidad. "Feliz" permite disminuir la distancia entre copia y original, pero a la vez, la conserva irremediablemente. Por eso, decir que el país es la copia "feliz" es lo mismo que decir "infeliz" toda vez que ambos términos no hacen más que corroborar la diferencia ontológica entre copia y original. Se argumenta que el término "feliz" constituye un dispositivo teológico político, toda vez que replica la función angélica destinada a la administración de la creación divina. En estos términos se pregunta: ¿no será el proyecto de la República de Chile un proyecto esencialmente administrativo? A esta luz, el texto plantea la contraposición entre himno con el poema: el himno -se plantea- constituye el operador angélico que hace posible la articulación de una soberanía. El poema, en cambio, constituiría el resto irreductible que le resiste. This essay asks on the performative efects of the chilean hymn, because it names the country as a "happy copy of Eden". Since this problem, the essay asks: how could the copy may posits as the originality of the sovereignity? To solve the distance between the copy and the original and make posible the sovereignity´s operation, the hymn names the copy as "happy". The word "happy" supports the constitution of the sovereignity and reveals the limit of its own imposibility. "Happy" reduce the distance between the copy and the original but, at the same time, absolutely preserve it. That´s why, say that the country is the "happy" copy is the same than to say that is a "unhappy" one, because both words shows the ontological difference between the copy and the original. This essay argues that the word "happy" is a political theological device because repeats the angelical task of manage the divine creation. In theses terms we ask: ¿Is the chilean republican proyect an administrative one? In this light, the essay posits an aporia between the hymn and poem: the hymn constitutes the angelical operator that makes sovereignity posible, the poem constitutes a singular rest that resist it.

Como expuso Walter Lippmann en su libro La opinión pública, en sociedades complejas como la nuestra los medios de comunicación de masas construyen un pseudoentorno, a través del cual nos hacen llegar las informaciones necesarias para nuestra vida cotidiana. Pero, los medios de comunicación hacen algo más que informarnos: eligen y organizan jerárquicamente nuestro menú cotidiano de informaciones relevantes. Conjuntamente con los agentes sociales, económicos y políticos prominentes, determinan la agenda de las preocupaciones ciudadanas, colocando en primer plano de la (...) actualidad determinados asuntos y silenciando o soslayando otros. Por esa razón, en la sociedad actual el concepto de opinión pública es incomprensible sin referirnos a la actuación de los medios de comunicación. Pero no se trata únicamente de la labor de los media como vehículos para la información y plataformas para la discusión colectiva. Los media popularizan valores, actitudes y modelos de conducta y su enorme capacidad de influir despierta una razonable preocupación entre los ciudadanos. Esta comunicación analiza siete cuestiones que ilustran las fricciones entre ciudadanía y medios de comunicación en la sociedad contemporánea. (shrink)

Em Ser e Tempo, Heidegger argumenta que o conhecimento primordial do Dasein se dá no manuseio de entes mundanos. Merleau-Ponty, por sua vez, descreve na Fenomenologia da Percepção que o conhecimento é, antes de tudo, uma intencionalidade corporal intraduzível em termos proposicionais. Mais tarde, em What Computers Can’t Do, Hubert Dreyfus usa a obra de ambos para apontar os equívocos do paradigma cognitivista, isto é, a abordagem dominante do então nascente campo da inteligência artificial. Finalmente, em The Embodied Mind: Cognitive (...) Science and Human Experience, a noção de enativismo - elaborada por Francisco Varela, Evan Thompson e Eleanor Rosch - surge como uma tentativa de tomar do cognitivismo e do conexionismo a hegemonia nas ciências cognitivas. Dito isso, o objetivo do artigo consiste em descrever o enativismo e apontar sua herança fenomenológica. (shrink)

This paper explores the main philosophical approaches of David Hilbert’s theory of proof. Specifically, it is focuses on his ideas regarding logic, the concept of proof, the axiomatic, the concept of truth, metamathematics, the a priori knowledge and the general nature of scientific knowledge. The aim is to show and characterize his epistemological approach on the foundation of knowledge, where logic appears as a guarantee of that foundation. Hilbert supposes that the propositional apriorism, proposed by him to support mathematics, sustains (...) — on its turn — a general method for the treatment of the problem in other areas such as natural sciences. This method is axiomatic. Broadly speaking, we intend to recover and update the Hilbert’s philosophical thinking about the role of logic for scientific knowledge. (shrink)

I analyze the theoretical tenets of early ethology and the criticisms leveled against it from comparative psychology. Early ethology had a clear research object, the study of behavioral adaptedness. Adaptedness was explained by the functional rules and programs that underlie the relation between a given organism and its natural environment (the function cycle). This research object was lost during the redefinition of ethology that took place after the Second World War, a redefinition that led to an emphasis on physiological and (...) evolutionary explanations instead of functional ones. This loss happened because early ethologists did not make their aims sufficiently clear and because of fundamental epistemological and semantic misunderstandings between ethologists and comparative psychologists. I argue that the behavioral explanation of adaptedness is different from both physiological and ecological research and that it needs functional concepts similar to the ones of early ethology. I defend the idea of function cycles and causal centers defined in terms of perceptual selection and behavioral response tendencies and I try to show that these functional concepts may be fruitfully combined with learning theories. I suggest calling this line of research Comparative Behavioral Ethology. (shrink)

O presente artigo aborda a situação do ensino da filosofia na conjuntura histórica da educação brasileira. Por meio de uma pesquisa bibliográfica e documental propõe-se a investigar as condições que o ensino da filosofia tem de se (a)firmar como condição à promoção do pensamento autônomo no ensino básico, dentro do espaço que lhe é reservado no atual contexto educacional brasileiro, marcado por reformas de cunho neoliberal, voltadas aos interesses do mercado. Partindo da concepção de filosofia como criação de conceitos, compreende-se (...) como sua principal função em sala de aula, entre outras, apresentar-se como um ambiente livre das demandas externas estabelecidas pelos programas oficiais de ensino, no qual os estudantes tenham possibilidades de desenvolver o pensamento autônomo e construir sua subjetividade de forma desprendida. Essa atribuição requer determinados requisitos como a presença da filosofia enquanto disciplina, professores especializados na área e tempo livre e de qualidade o suficiente para o exercício do pensar autônomo, as quais se encontram ausentes, em sua maioria, no modelo de ensino que está sendo implementado. No atual cenário, marcado por reformas guiadas por tendências neoliberais que submetem a educação aos interesses da economia, o espaço da filosofia no ensino básico encontra-se reduzido e ameaçado. Tais mudanças reforçam o dualismo presente na educação brasileira, o qual atribui uma formação geral à classe privilegiada e outra de cunho laboral à trabalhadora, impedindo a implantação de uma formação humana integral para todos(as), na qual a filosofia ocupa papel fundamental. Compreende-se por fim que, apesar do cenário desfavorável, resta à filosofia criar formas de resistência, dentro e fora da escola para poder se (a)firmar. (shrink)

O presente artigo tem como propósito discutir sobre as origens e os desdobramentos da maquinação na história do pensamento ocidental. Para tanto, fazemos uma leitura ontológica-fenomenológica da questão da técnica a partir das meditações de Heidegger, sobretudo na obra Contribuições à Filosofia, publicada em 1989. As reflexões aqui presentes pensam a maquinação como uma disposição que, em sua gênese, revela-se como um acontecimento além da força e da vontade do homem, destacando o abandono e o esquecimento do ser como eventos (...) fundantes da história. Buscamos evidenciar o verdadeiro sentido da condição histórica dos entes no contexto contemporâneo ao demonstrarmos como o ocultamento e a ausência do ser representam o fundo originário da existência. Assim, o ponto fundamental deste texto é a indicação de que o vigor da ausência essencial pode possuir robustez mais profunda do que a presença de qualquer ente. (shrink)

Resumen: El presente artículo propone una visión estructural de la e-justicia por contraposición al reduccionismo metodológico e instrumental actual que la concibe como la simple incorporación de los dispositivos tecnológicos de la información y de la comunicación a la función pública judicial de impartir justicia, cuando más, a una transformación cultural del órgano judicial. El análisis plantea que la justicia es un concepto medular de la estabilidad social, que no se agota en la funcionalidad judicial, que depende de las asignaciones (...) estimativas acerca de aquello que para cada sociedad significa la armonía o la armonización social en relación con la interferencia de las conductas entre los individuos que la conforman. Con la introducción de la teoría de la impetración de la justicia se propone que la sociedad sea un componente activo de la gestión conflictiva a partir de la idea de justicia que se construye de igual forma, sin permitir que se le conciba como un simple receptor de la demanda de justicia que de forma vertical entrega la organización pública al margen de la realidad social, que ha adquirido una nueva configuración con la eclosión de la tecnología en todos los ámbitos de la vida humana.: This paper proposes a structural vision of e-justice as opposed to the current methodological and instrumental reductionism that conceives it as the simple incorporation of information and communication technology devices to the judicial public function of imparting justice, or at most, to a cultural transformation of the judicial body. The analysis suggests that justice is a core concept of social stability, which is not exhausted in the judicial functionality, which depends on the estimative allocations about what for each society means harmony or social harmonization in relation to the interference of behaviors between the individuals that comprise it. With the introduction of the theory of the impetration of justice, it is proposed that society be an active component of conflict management based on the idea of justice that is constructed in the same way, without allowing it to be conceived as a simple receiver of the demand for justice that is delivered vertically by the public organization at the margin of social reality, which has acquired a new configuration with the emergence of technology in all areas of human life.

Music may have a strong influence on literature. Many novels have reflected this by thematizing music in many different ways. However, this engagement can also adopt the form of an imitation or a formal presence that does not actually require the text to say anything about music. This paper aims to explore some aspects of musical imitation in literature that have not been analyzed in depth. Departing from the approach developed by Werner Wolf, I propose a distinction between imitating and (...) imitated elements that applies to any case of study. Furthermore, at the core of this article, I advocate for a fourth dimension that the imitation of music in literature may have and that should be added to word music, formal and structural analogies, and imaginary content analogies. I call this fourth category “graphic analogies.” It implies an imitation whose imitating element is the graphic, written aspect of the linguistic signifier. Finally, this leads to the idea that, in the case of the imitation of music in literature, there is not a necessary correlation between imitating and imitated elements. (shrink)

This article reports on ethnographic research into the practical and ethical consequences of the implementation and use of telecare devices for older people living at home in Spain and the United Kingdom. Telecare services are said to allow the maintenance of their users’ autonomy through connectedness, relieving the isolation from which many older people suffer amid rising demands for care. However, engaging with Science and Technology Studies literature on “user configuration” and implementation processes, we argue here that neither services nor (...) users preexist the installation of the service: they are better described as produced along with it. Moving beyond design and appropriation practices, our contribution stresses the importance of installations as specific moments where such emplacements take place. Using Etienne Souriau’s concept of instauration, we describe the ways in which, through installation work, telecare services “bring into existence” their very infrastructure of usership. Hence, both services and telecare users are effects of fulfilling the “felicity conditions” of an achieved installation. (shrink)

RésuméLe présent article propose la liste des œuvres médicales composées par Ibn Bājja, donne une présentation synthétique de celles qui nous ont été transmises et étudie le métacommentaire au commentaire de Galien sur lesAphorismesd'Hippocrate (Sharḥ fī al-Fuṣūl). Ce texte montre une influence profonde d'al- Fārābī, en particulier dans sa conception de l'expérience médicale, qui remonte à la façon dont ce dernier construit l'expérience (tajriba) comme le procédé inductif, décrit par Aristote dans lesSeconds Analytiques, produisant les prémisses de la démonstration. Sur (...) cette base, Ibn Bājja défend la pertinence d'une médecine moins scolastique et plus empirique, une position dont Ibn Rushd se fera l'écho. Des similitudes entre le texte d'Ibn Bājja et leK. al-Kulliyyāt fī al-ṭibbd'Ibn Rushd suggèrent que celui-ci avait lu leSharḥ fī al-Fuṣūl. Cette œuvre, en outre, pourrait bien attester que la dissection humaine était pratiquée à l'époque d'Ibn Bājja. (shrink)

Establishing phonologically robust lexical representations in a second language is challenging, and even more so for words containing phones in phonological contrasts that are not part of the native language. This study presents a series of additional analyses of lexical decision data assessing the phonolexical encoding of English /ε/ and /æ/ by German learners of English in order to examine the influence of lexical frequency, phonological neighborhood density and the acoustics of the particular vowels on learners’ ability to reject nonwords (...) differing from real words in the confusable L2 phones only. Results showed that both the lexical properties of the target items and the acoustics of the critical vowels affected nonword rejection, albeit differently for items with /æ/ → [ε] and /ε/ → [æ] mispronunciations: For the former, lower lexical frequencies and higher neighborhood densities led to more accurate performance. For the latter, it was only the acoustics of the vowel that had a significant impact on learners’ accuracy. This suggests that the encoding of /ε/ and /æ/ may not only be asymmetric in that /ε/ is generally more robustly represented in the lexicon than /æ/, as previously reported, but also in the way in which this encoding takes place. Mainly, the encoding of /æ/ appears to be more dependent on the characteristics of the L2 vocabulary and on one’s experience with the L2 than that of its more dominant counterpart. (shrink)

Freezers with biospecimen deposits became biobanks and later were networked at the pan-European level in 2013 under the Biobanking and BioMolecular Resources Research Infrastructure—European Research Infrastructure Consortium (BBMRI-ERIC). Drawing on document analysis about the BBMRI-ERIC and multi-sited fieldwork with biobankers in Spain from a science and technology studies approach, we explore what biobanks are expected to do and become under the BBMRI-ERIC framework, and how infrastructural transitions promote particular transformations in biobanking practices. The primary purpose of biobanks in Europe is (...) presented as being to become mediators in contemporary biomedical research (global sharing nodes) distribution, and distributed nodes of samples and their associated data. We argue that infrastructural transitions are complicated and heterogeneous, giving rise to unattended local concerns on adjusting their practices to fit into the BBMRI-ERIC framework, even for non-members, as the case of Spain illustrates, where “old practices” of collection and storage are questioned. In this article, we aim to encourage qualitative studies to explore the lags between pan-European policies and prospects, different contextual interpretations, and biobanking reconfigurations as an opportunity to explore what that lag is made of (e.g. tensions with “old practices,” unresolved conflicts with the national agendas, reservations on a possible centralization of the biobanking practices by regional biobanks, lack of funding, etc.). Such research could enrich not only policy guidance, but also the understanding of technoscientific infrastructures’ scalability. (shrink)

El presente artículo defiende que en _ Gorgias _ 521d Sócrates se atribuye a sí mismo una forma genuina de saber político. Para ello, se abordan los problemas planteados por la crítica reciente en lo que respecta a la aparente incompatibilidad de dicha atribución con (1) el reconocimiento explícito en _ Gorgias _ de no poseer un saber referido a lo justo, y (2) la aparente invalidez de la actividad desarrollada por Sócrates para contar, bajo los criterios que él mismo (...) establece en el _ Gorgias _, como efectivamente política. El trabajo responde a estas dificultades realizando un análisis del tipo de naturaleza que Sócrates atribuye a su propio saber en esta obra, así como de los efectos que su actividad dialógica demuestra ser capaz de producir sobre Calicles.

Este artículo estudia la relación entre bien y conocimiento en la República de Platón, en diálogo con la recepción de esta temática en la obra del filósofo Leonardo Polo. Para ello, se ofrece, en primer lugar, una reconstrucción de la lectura del bien platónico en la obra poliana a lo largo de los años 80 y 90. A continuación, y a partir de un análisis de los textos relevantes de la República, se discute la interpretación de Polo en lo que (...) respecta al acceso al bien y al tipo de causalidad del bien en relación con el conocimiento. El presente artículo propone una lectura alternativa que cuestiona la tesis poliana según la cual la doctrina aristotélica sobre el conocimiento como acto es radicalmente incompatible con la epistemología platónica.

One of the most urgent debates of our time is about the exact role that new technologies can and should play in our societies and particularly in our public decision-making processes. This paper is a first attempt to introduce the idea of CrowdLaw, defined as online public participation leveraging new technologies to tap into diverse sources of information, judgments and expertise at each stage of the law and policymaking cycle to improve the quality as well as the legitimacy of the (...) resulting laws and policies. First, we explain why CrowdLaw differs from many previous forms of political participation. Second,we reproduce and explain the CrowdLaw Manifesto that the rising CrowdLaw community has elaborated to foster such approaches around the world. Lastly, we introduce some preliminary considerations on the notions of justice, legitimacy and quality of lawmaking and public decision-making, which are central to the idea of CrowdLaw. (shrink)

In a seminal work, Tversky and Kahneman showed that in some contexts people tend to believe that a conjunction of events (e.g., Linda is a bank teller and is active in the feminist movement) is more likely to occur than one of the conjuncts (e.g., Linda is a bank teller). This belief violates the conjunction rule in probability theory. Tversky and Kahneman called this phenomenon the “conjunction fallacy”. Since the discovery of the phenomenon in 1983, researchers in psychology and philosophy (...) have engaged in important controversies around the conjunction fallacy. The goal of this paper is to explore the most important of these controversies, namely, the controversy about the nature of the conjunction fallacy. Is the conjunction fallacy mainly due to a misunderstanding of the problem by participants (misunderstanding hypothesis) or is it mainly due to a genuine reasoning bias (reasoning bias hypothesis)? A substantial portion of research on the topic has been directed to test the misunderstanding hypothesis. I review this literature and argue that a stronger case can be made against the misunderstanding hypothesis. Thus, I indirectly provide support for the reasoning bias hypothesis. (shrink)

The present paper examines the relationship between explicit and implicit memory and ultimate attainment in the native language. Two groups of native speakers of English with different levels of academic attainment (i.e., high vs. low) took part in three language tasks which assessed grammar, vocabulary and collocational knowledge, as well as phonological short-term memory (assessed using a forward digit-span task), explicit associative memory (assessed using a paired-associates task) and implicit memory (assessed using a deterministic serial reaction time task). Results revealed (...) strong relationships between phonological short-term memory and explicit associative memory on the one hand and the three language tasks on the other hand, and no relation between linguistic performance and implicit memory. Taken together, these results cast doubts on the common assumption that L1 grammar learning depends almost entirely on implicit memory and align with the claims of usage-based models of language acquisition that grammatical and lexical knowledge depend on the same cognitive mechanisms.

The aim of being able to reason about quantities, time or space has been the main objective of the many efforts on the integration of propositional planning with extensions to handle different theories. Planning modulo theories are an approximation inspired by satisfiability modulo theories that generalize the integration of arbitrary theories with propositional planning. Parallel plans are crucial to reduce plan lengths and hence the time needed to reach a feasible plan in many approaches. Parallelization of actions relies on the (...) notion of interference, which is usually determined syntactically at compile time. In this paper we define a semantic notion of interference between actions in PMT. Apart from being strictly stronger than any syntactic notion of interference, we show how semantic interference can be easily and efficiently checked by calling an off-the-shelf SMT solver at compile time, constituting a technique orthogonal to the solving method.

Are feelings an essential part or aspect of emotion? Cases of unconscious emotion suggest that this is not the case. However, it has been claimed that unconscious emotions are better understood as either (a) emotions that are phenomenally conscious but not reflectively conscious, or (b) dispositions to have emotions rather than emotions proper. Here, I argue that these ways of accounting for unconscious emotions are inadequate, and propose a view of emotions as non-phenomenal attitudes that regard their contents as relevant (...) to one's motivations.
