Commentary to Leslie McCall's 2005 paper "The complexity of intersectionality", with a review of her main points and some critical remarks.

Whereas intersectionality presents a fruitful framework for theoretical and empirical research, some of its fundamental features present great confusion. The term ‘intersectionality’ and its metaphor of the crossroads seem to reproduce what it aims to avoid: conceiving categories as separate. Despite the attempts for developing new metaphors that illustrate the mutual constitution relation among categories, gender, race or class keep being imagined as discrete units that intersect, mix or combine. Here we identify two main problems in metaphors: the lack of (...) differentiation between positions and effects and the problem of reification. We then present a new metaphor that overcomes these two problems: a basket of apples. We argue that considering social positions as the diverse properties of different apples avoids reification by considering categories as properties and not as objects themselves, and at the same time it allows us to think about the effects dimension from a plural and contextual approach. With this shift, we propose a reframing of the discussion in debates on intersectionality theory on the relation among categories, their in/separability and fragmentation. (shrink)

In this paper art history and visual studies, the disciplines that study visual culture, are presented as a field whose conjectural paradigm can be used to understand the epistemic problems associated with abduction. In order to do so, significant statements, concepts and arguments from the work of several specialists in this field have been highlighted. Their analysis shows the fruitfulness and potential for understanding the study of visual culture as a field that is interwoven with the assumptions of abductive cognition.

This paper has a twofold aim. On the one hand, we will discuss the much debated question of the source of normativity (which traditionally has nature and practical reason as the two main contenders to this role) and propose a new answer to it. Second, in answering this question, we will present a new account of practical wisdom, which conceives of the ethical virtues as ultimately unified in the chief virtue of phronesis, understood as ethical expertise. To do so, we (...) will first criticize the main current view of phronesis and its bearer (the phronimos), then offer another view of the nature of phronesis and of its relation to the other ethical virtues. Our proposal should not be intended as an interpretation of Aristotle’s own view; rather, it should be seen as a broadly Aristotelian theoretical proposal, which we believe can satisfyingly address most of the problems that afflict the more traditional accounts of practical wisdom. In section 2 of this paper, after criticizing first-nature naturalistic views of moral virtue, we take practical reason to be the cornerstone of second-nature naturalistic views; in section 3, we will outline criticisms to which, in our view, the traditional views of phronesis are ill-suited to respond, and, in section 4, we will outline our view of phronesis as ethical expertise – a view which in our view is immune to the above-mentioned criticisms – by spelling out the three main tenets of phronesis as ethical expertise: a conceptual thesis, an epistemic thesis, and the educational implications of the two. Finally, we will support our proposal with some empirical evidence taken from cognitive science. (shrink)

Sentada en un bar, mientras Simone de Beauvoir lee mi artículo de la semana pasada, la miro. Ninguna madre burguesa tendría de qué quejarse: la señora Beauvoir tiene una blusa cuidadosamente planchada; está fresca como una rosa, su rostro es terso y limpio, de ella emana un discreto perfume, es verdaderamente perfecta. Su rebelión contra su familia y su entorno, tan bien descrita en las Memorias de una joven formal, no se muestra en los detalles de la vestimenta. No, definitivamente, (...) Simone de Beauvoir no tiene la agresividad "amazónica" al límite. (shrink)

This paper analyses the phenomenology and epistemology of chatbots such as ChatGPT and Bard. The computational architecture underpinning these chatbots are large language models (LLMs), which are generative AI (Artificial Intelligence) systems trained on a massive dataset of text extracted from the Web. We conceptualise these LLMs as multifunctional computational cognitive artifacts, used for various cognitive tasks such as translating, summarizing, answering questions, information-seeking, and much more. Phenomenologically, LLMs can be experienced as a “quasi-other”; when that happens, users anthropomorphise them. (...) For most users, current LLMs are black boxes, i.e., for the most part, they lack data transparency and algorithmic transparency. They can, however, be phenomenologically and informationally transparent, in which case there is an interactional flow. Anthropomorphising and interactional flow can, in some users, create an attitude of (unwarranted) trust towards the output LLMs generate. We conclude this paper by drawing on the epistemology of trust and testimony to examine the epistemic implications of these dimensions. Whilst LLMs generally generate accurate responses, we observe two epistemic pitfalls. Ideally, users should be able to match the level of trust that they place in LLMs to the degree that LLMs are trustworthy. However, both their data and algorithmic opacity and their phenomenological and informational transparency can make it difficult for users to calibrate their trust correctly. The effects of these limitations are twofold: users may adopt unwarranted attitudes of trust towards the outputs of LLMs (which is particularly problematic when LLMs hallucinate), and the trustworthiness of LLMs may be undermined.

In this chapter, we will offer a sketch of the state of the art as concerns existing accounts of virtue acquisition in relation to automaticity. In particular, we will focus on the so-called “skill model,” which we aim to improve by questioning its rather common underlying dualistic picture of the mind. Then we will propose an account of skillful emotions by identifying the features that make them both automatic and embedded in an intelligent practice. Finally, we will show how this (...) view can help the skill model by offering a better description of emotion shaping in virtue acquisition. By doing so, we will contend that emotions contribute autonomously and actively to the skillfulness of the habits in which they are embedded. (shrink)

Pulcro, sobrio, comedido, preciso, cotidiano, manual, podrían ser calificativos (demasiado fácilmente) aplicables al trabajo de Amaya Bombín. Como si se tratara de la labor de una cirujana, de una bordadora, de una artesana, de un ama de casa. Si afirmáramos esto no solamente estaríamos recurriendo a tópicos sobradamente manidos cuando se trata de hablar de la obra de mujeres artistas, sino que además estaríamos desviando nuestra atención de lo que se nos ha dado a experimentar para reflexionar.

Ante estas obras de Victoria Diehl es fácil pensar en conocidos modelos anatómicos en cera o en la iconografía de Venus y Evas de las que un vistazo rápido a cualquier libro de historia del arte nos mostraría múltiples variantes.

Hermes, al trasladar (...) sus mensajes los interpreta, los adapta al interlocutor y al medio; los transforma, los traduce, los recrea. Y logra ponernos en movimiento. [...]. (shrink)

O debate em torno do não conceitualismo kantiano ganhou notoriedade nas pesquisas em filosofia kantiana contemporânea desde a publicação do artigo de Robert Hanna, em 2005, Kant and nonconceptual content (“Kant e o conteúdo não conceitual”). Desde então, muito tem sido discutido sobre essa nova leitura da doutrina do idealismo transcendental que busca compatibilizá-la com os argumentos não conceitualistas da filosofia analítica. Procuramos mostrar de que forma a intuição pura do espaço, enquanto forma a priori da sensibilidade, introduz uma estrutura (...) espacial-egocêntrica na experiência perceptiva, que não requere a função da síntese governada por conceitos, própria da faculdade do entendimento, e que permite estruturar um tipo de conteúdo cuja natureza é não conceitual. Para atingir tal objetivo, esta dissertação foi dividida em três capítulos. No primeiro, abordamos o desenvolvimento da doutrina da idealidade transcendental do espaço e do tempo que culmina na tese das formas puras não conceituais da sensibilidade. No segundo capítulo, fazemos um apanhado do debate entre conceitualistas e não conceitualistas na contemporaneidade. Mais especificamente, abordamos os problemas que regem a posição conceitualista padrão, pautada principalmente por John McDowell, e as respostas não conceitualistas que se desenvolveram a partir da posição de Gareth Evans, com foco especial na teoria do espaço egocêntrico. No terceiro capítulo, por fim, abordamos os principais problemas que a posição não conceitualista kantiana precisa enfrentar quando propõe que a doutrina da idealidade transcendental do espaço e do tempo seja compatível com a tese do conteúdo não conceitual da experiência.

The appearance of openly accessible Artificial Intelligence Applications such as Large Language Models, nowadays capable of almost human-level performances in complex reasoning tasks had a tremendous impact on public opinion. Are we going to be "replaced" by the machines? Or - even worse - "ruled" by them? The behavior of these systems is so advanced they might almost appear "alive" to end users, and there have been claims about these programs being "sentient". Since many of our relationships of power and (...) social dominance are apparently based on intelligence, where the "smarter" seems to prevail on the "dumber" (as we see for example with livestock farming, or with the distribution of salaries according to formal and intellectual qualifications etc.) the emergence of programs and AI applications of this level of sophistication brings us to the question "what will AI do to us?". Our error is to frame Artificial Intelligence in the same way we frame Natural Intelligence and mistakenly address it as we would do with biological life, even applying to it the same biopolitical categories. We here try to reverse the common arguments in relationship between life and intelligence and show that our progresses in Artificial Intelligence might have no immediate consequence for the topic of life as such, as life and intelligence are well separated issues, and - even when we would like to somehow fuse them together, we are very far away from having an "Artificial Life" to the degree of complexity and effectiveness we have with "Artificial Intelligence".

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

Many approaches have been taken regarding this topic, some of them are anthropological or scientific that pursue the understanding of why we eat meat, but from the philosophical lens this question is solved in the field of applied ethics, which is the area that debate about the moral status of animals (nonhuman animals) and where different theorizations that tried to explain the relationship between animals and humans and the examination of the morality of meat consumption take place. Some of these (...) approaches could be find within the concepts of animal rights, vegetarianism, animal cruelty and so on. (shrink)

One way to detect, monitor and prevent adverse events with the help of Information Technology is by using ontologies capable of representing three levels of reality: what is the case, what is believed about reality, and what is represented. We report on how Basic Formal Ontology and Referent Tracking exhibit this capability and how they are used to develop an adverse event ontology and related data annotation scheme for the European ReMINE project.

Ignorance is often a perfectly good excuse. There are interesting debates about whether non-culpable factual ignorance and mistake subvert obligation, but little disagreement about whether non-culpable factual ignorance and mistake exculpate. What about agents who have all the relevant facts in view but fail to meet their obligations because they do not have the right moral beliefs? If their ignorance of their obligations derives from mistaken moral beliefs or from ignorance of the moral significance of the facts they have in (...) view, should they be excused for failing to meet their moral obligations? It is not obvious that they should. In this paper we argue that the best non-skeptical accounts of moral responsibility acknowledge that factual ignorance and mistake will diminish moral responsibility in a way that moral ignorance and mistake will not. That is because factual ignorance is often non-culpable so long as it meets certain merely procedural epistemic standards but the same is not true of moral ignorance. Our argument is that the assumption that it is gets the standards of culpability for moral ignorance wrong, and that the mistake is encouraged by the thought that culpability in general requires an instance of known wrongdoing: that acting wrongly requires de dicto unresponsiveness to one’s obligations at some stage. We deny this and conclude that, therefore, ignorance and mistaken belief are indeed often perfectly good excuses – but far less often than some philosophers claim. (shrink)

This paper introduces a framework for direct surface composition by online update. The surface string is interpreted as is, with each morpheme in turn updating the input state of information and attention. A formal representation language, Logic of Centering, is defined and some crosslinguistic constraints on lexical meanings and compositional operations are formulated.

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

The aim of this paper lies in characterizing the explanations and models used in the field of evolutionary developmental biology throughout its history. While manipulative experiments in controlled conditions have been useful to set the bases of the discipline and are still routinely performed, this approach supposes a tension between the reliability and the representativity of the conclusions. Given the recent changes in the understanding of evolutionary phenomena, different authors currently emphasize the need of avoiding excessive simplifications in experimental approaches, (...) incorporating the complexity of the analyzed systems as a relevant trait in the study of biological diversity. On the other hand, the fragile and contingent nature of evolutionary processes and the impossibility of intervening some of these phenomena underscore the importance of non-manipulative models that allow the elucidation of how-possibly mechanisms. We argue that a pluralism characterized by the integration of different kinds of explanations, models and metaphors used in evo-devo allows to exploit their respective advantages, favours interdisciplinarity and can contribute to form a representative description of evolutionary processes without relinquishing the local and detailed study of actual mechanisms.

The discipline of knowledge translation (KT) emerged as a way of systematically understanding and addressing the challenges of applying health and medical research in practice. In light of ongoing and emerging critique of KT from the medical humanities and social sciences disciplines, KT researchers have become increasingly aware of the complexity of the translational process, particularly the significance of culture, tradition and values in how scientific evidence is understood and received, and thus increasingly receptive to pluralistic notions of knowledge. Hence, (...) there is now an emerging view of KT as a highly complex, dynamic, and integrated sociological phenomenon, which neither assumes nor creates knowledge hierarchies and neither prescribes nor privileges scientific evidence. Such a view, however, does not guarantee that scientific evidence will be applied in practice and thus poses a significant dilemma for KT regarding its status as a scientific and practice-oriented discipline, particularly within the current sociopolitical climate. Therefore, in response to the ongoing and emerging critique of KT, we argue that KT must provide scope for relevant scientific evidence to occupy an appropriate position of epistemic primacy in public discourse. Such a view is not intended to uphold the privileged status of science nor affirm the “scientific logos” per se. It is proffered as a counterbalance to powerful social, cultural, political and market forces that are able to challenge scientific evidence and promote disinformation to the detriment of democratic outcomes and the public good.

The data analyzed in this paper are part of the results described in Bueno et al. (2000). Three cytogenetics endpoints were analyzed in three populations of a species of wild rodent – Akodon montensis – living in an industrial, an agricultural, and a preservation area at the Itajaí Valley, State of Santa Catarina, Brazil. The polychromatic/normochromatic ratio, the mitotic index, and the frequency of micronucleated polychromatic erythrocites were used in an attempt to establish a genotoxic profile of each area. It (...) was assumed that the three populations were in the same conditions with respect to the influence of confounding factors such as animal age, health, nutrition status, presence of pathogens, and intra- and inter-populational genetic variability. Therefore, any differences found in the endpoints analyzed could be attributed to the external agents present in each area. The statistical models used in this paper are mixtures of negative-binomials and Poisson variables. The Poisson variables are used as approximations of binomials for rare events. The mixing distributions are beta densities. The statistical analyzes are under the bayesian perspective, as opposed to the frequentist ones often considered in the literature, as for instance in Bueno et al. (2000). (shrink)

Pocos otros temas despiertan más polémicas que el de los vínculos entre filosofía y política: que quienes se dedican a la filosofía no deben verse influenciados por la política, que si a la política le corresponde ser auxiliada por la filosofía, que si el saber filosófico tiene que desligarse de las posiciones políticas, que si a las instituciones académicas de las humanidades les conviene independizarse del poder de turno, etc. Todas estas son discusiones que heredamos (no sin reformularlas y, por (...) lo tanto, retransformarlas) desde la Antigüedad, en la que ya aparecería, de la mano de Platón, la figura del rey filósofo. Este libro reúne una variedad de abordajes que atraviesan debates sobre juicios de hecho y de valor, sobre la democra-cia como forma de gobierno y sobre la intervención de la historia en el vínculo de la filosofía y la política. Recuperando el pensamiento antiguo y moderno, pero concentrándose en la obra de intelectuales contemporáneos, los autores ponen en movimiento dilucidaciones de grandes como Max Weber, Jacques Rancière, Louis Althusser, Philippe Lacoue-Labarthe y Leo Strauss, entre otros. Así, ofrecen aquí un vívido panorama de las controversias que habitan los entrecruzamientos entre filosofía y política, coronando el volumen con la traducción de un texto de Claude Lefort, hasta el momento inédito en español.

El Foro Global de Bioética en Investigación (GFBR por sus siglas en inglés) se reunió el 3 y 4 de noviembre en Buenos Aires, Argentina, con el objetivo de discutir la ética de la investigación con mujeres embarazadas. El GFBR es una plataforma mundial que congrega a actores clave con el objetivo de promover la investigación realizada de manera ética, fortalecer la ética de la investigación en salud, particularmente en países de ingresos bajos y medios, y promover colaboración entre países (...) del norte y del sur.a Los participantes en el GFBR provenientes de Latinoamérica incluyeron a eticistas, investigadores, miembros de comités de ética y representantes de autoridades sanitarias provenientes de Argentina, Brasil, Chile, Colombia, Ecuador, El Salvador, Guatemala, Honduras, Panamá, Perú, Nicaragua y la República Dominicana. Una legítima preocupación por la protección de las mujeres embarazadas y sus embriones o fetos ha llevado a la mayoría de los países de la Región de las Américas a limitar la realización de estudios con mujeres embarazadas exclusivamente a aquellos estudios específicos sobre el embarazo, y a requerir la exclusión sistemática de las mujeres embarazadas o de las mujeres que quedan embarazadas en el curso del estudio. Ciertamente, a lo largo de la historia de la ética de la investigación, se ha creído erróneamente que proteger a una población es sinónimo de excluirla de los estudios. Se sabe ahora que proceder así implica exponer a riesgos mucho mayores a la población que se busca proteger. El embarazo implica cambios fisiológicos sustantivos e impacta profundamente la manera como el cuerpo metaboliza los medicamentos. Sin embargo, por evitar hacer investigación con mujeres embarazadas, no se ha producido la evidencia científica necesaria para tomar decisiones sobre tratamientos e intervenciones preventivas con dosis eficaces y seguras para ellas y sus embriones o fetos. A manera de ilustración, en el 2001 había en los Estados Unidos apenas más de una docena de medicamentos aprobados para uso en el embarazo (1) y en el 2011 la Food and Drug Administration (FDA) aprobó por primera vez en 15 años un medicamento para su uso en el embarazo (2). Como consecuencia de no haber producido la evidencia necesaria, se pone en riesgo la salud de las mujeres embarazadas cada vez que se les da atención médica. Las mujeres embarazadas se enferman y las mujeres enfermas se embarazan, y no se sabe si los medicamentos que se les da son eficaces o siquiera seguros para ellas y sus embriones o fetos. (shrink)

Ante ciertos modelos causales del agente libre inspirados en Tomás de Aquino, resulta interesante atender al modelo causal presentado por Tomás mismo, especialmente en un texto a partir del cual se puede rastrear la exposición de la acción libre como el efecto de los cuatro sentidos causales aristotélicos. Se trata de la cuestión sobre los actos imperados (ST I–II, q. 17); en cuyos primeros cuatro artículos –y en sus textos paralelos– determina que la voluntad es causa agente; la razón práctica, (...) causa ordenadora; y el imperium de ambas (razón y voluntad) se relaciona con el acto imperado como lo formal con lo material.

In this Interview, Professor Robert B. Brandom answered ten detailed questions about his philosophy of Rational Pragmatism and Semantic Expressivism, grouped into four topics. 1. Metaphysics and Anthropology, 2. Pragmatics and Semantics, 3. Epistemic Expressivism and 4. Philosophy of Logic. With his careful answers Professor Brandom offers many additional insights into his rigorously constructed account of the relationship “between what we say and think, and what we are saying and thinking about” around the human practice of asking for and giving (...) reasons. A final, additional question pointed at a principal motivation for putting together the present issue: how to reconcile Wittgenstein’s assertion that philosophy must not proffer any theories with the very explicit system of explanations Brandom has constructed. This same issue is addressed to some extent already in Professor Brandom’s new article contained in this issue, but his answer, asserting that he does not proffer a theory but only makes explicit what is already there, might be seen as an unambiguous statement of the continuous presence of a contested Wittgensteinian principle in Brandom’s work.

El estudio y análisis de las argumentaciones cotidianas entendidas como interacciones discursivas e intencionales encaminadas a dar cuenta de algo con el fin de lograr que aquello que se sostiene sea aceptado, sería inconcebible sin la aparición de la teoría de los actos de habla de Austin (1962), la propuesta de Searle (1969), el trabajo de Grice sobre la teoría de la conversación (1975) y el importante estudio sistemático de Hamblin sobre el argumento falaz (1970). Como una reelaboración de dichas (...) obras cabe entender la teoría pragmadialéctica de la argumentación propuesta inicialmente por Frans H. van Eemeren y Rob Grootendorst (1984). Algunos autores (Blair, 2006: 11; Woods, 1992) creen ver en ella, más que una teoría, una amalgama de varias teorías y una particular versión de la teoría pragmadialéctica de la argumentación, entendiendo ésta bajo una acepción más general. Otros consideran que ni es útil ni tampoco especulativamente productivo sostener que de toda argumentación pueda buscarse un modelo según el cual ésta buscaría resolver una diferencia de opinión (Goodwin, 1999).

Protopolybia sedula is a social swarming wasp, widely spread throughout many countries in the Americas, including most of Brazil. Despite its distribution, studies of its behavioral ecology are scarce. This study aimed to describe its foraging activity and relation to climatic variables in the city of Juiz de Fora in southeastern Brazil. Three colonies were under observation between 07:00 and 18:00 during April 2012, January 2013, and March 2013. Every 30 minutes, the number of foragers leaving and returning to the (...) colony was registered along with air temperature and relative humidity. Activity began around 07:30¸ increased between 10:30 and 14:30, and ended around 18:30. A mean of 52.7 exits and 54 returns were measured every 30 minutes. The daily mean values were 1,107 ± 510.6 exits and 1,135 ± 854.8 returns. Only one colony showed a significant correlation between forager exits and temperature (rs = 0.8055; P < 0.0001) and between exits and relative humidity (rs = -0.7441; P = 0.0001). This paper shows that climatic variables are likely to have little control on the foraging rhythm of P. sedula when compared to other species, suggesting the interaction of other external and internal factors as stimuli of species foraging behavior.

«Fortaleza» y «debilidad» son dos adjetivos que se han utilizado prolijamente en la literatura científica sobre institucionalismo para describir la permanencia o, por el contrario, la porosidad y maleabilidad de las reglas y principios rectores en los que están atrincheradas las instituciones que sobreviven en equilibrio y, por tanto, no son alteradas unilateralmente.

Este artículo muestra la conexión entre heurísticas sociales y deliberación. En lugar de caracterizar las heurísticas según disciplinas o campos, aquí se proyectan sobre nuestros enclaves deliberativos. La autora sostiene que el empleo de heurísticas sociales orienta el flujo de la información y la participación en las distintas fases deliberativas, y es necesario analizarlas para establecer indicadores con los que medir grados de deliberación. Esta hipótesis da lugar a una visión pluralista sobre la función social de las heurísticas entendidas como (...) caja de herramientas con nuevos instrumentos y utilidades sociales. Según dicha perspectiva, habría que integrar este tipo de razonamiento en un plan de acción más amplio que explicara en qué sentido las heurísticas son recursos que producen conocimiento, al tiempo que un tipo de conocimiento ya producido.

La oposición a una estricta separación entre las dimensiones dialéctica y retórica de la actividad argumentativa es una de las aportaciones más destacadas y peculiares de la denominada escuela holandesa sobre argumentación. Frans H. van Eemeren y Peter Houtlosser reaccionaron contra una separación estricta entre dialéctica y retórica en varios trabajos, pero uno de los más inspiradores es sin duda su artículo “William the Silent’s argumentative discourse” (1998) presentado en la ciudad de Ámsterdam con ocasión de la cuarta conferencia organizada (...) por la International Society for the Study of Argumentation (ISSA). Sobre este tema siguieron investigando para presentar un análisis de la perspectiva dialéctica inherente al caso de Guillermo I de Orange en un congreso de la Japan Debate Association en Tokio (van Eemeren y Houtlosser, 2000).

Uno de los conceptos fundamentales del área de las Ciencias humanas y sociales es el de «cognición social». Este término se suele utilizar para referir teorías, categorías y principios que explican e interpretan fenómenos relacionados con el conocimiento que los seres humanos poseen sobre el mundo social.

Las definiciones de argumentación son tan variadas como las distintas posiciones existentes en torno a la pregunta de qué hacemos exactamente cuando argumentamos y cuándo estamos, de hecho, argumentando. Incluso el mismo autor puede ofrecer más de una definición de lo que entiende por argumentación; en parte, porque el problema de la argumentación no se circunscribe a un solo ámbito, ni del conocimiento ni de la vida práctica.

Thema der Arbeit ist der ontologische Status von Werken sowie die Beziehung zwischen Werken einerseits und Aufführungen, Manuskripten, Partituren, Schallplatten, Gemälden, Gebäuden, Drucken etc. andererseits. Es wird angeknüpft an den phänomenologischen Ansatz von Roman Ingarden (aber auch an den von Alexius Meinung). Diese Ansätze werden unter Verwendung moderner logischer Hilfsmittel weiterentwickelt und, wo notwendig, revidiert. Im ersten Kapitel wird ausführlich begründet, warum Werke (und zwar Werke aller Gattungen) abstrakte, typenartige Gegenstände sein müssen, die in konkreten Einzeldingen (z. B. Aufführungen) realisiert (...) sein können, jedoch von diesen Realisierungen in ihrer Existenz nicht abhängig sind. Diese These ist im weiteren Verlauf der Arbeit eine nicht mehr hinterfragte Grundvoraussetzung. Im zweiten Kapitel werden die formalen Grundlagen einer Typenontologie des Werks entwickelt. Zwei Hauptfragen stehen dabei im Vordergrund: (a) Wie kann ein Werk (also ein abstrakter Gegenstand) sinnliche Eigenschaften (z. B. Klangeigenschaften, Farbeigenschaften) haben? (b) Was macht einen Gegenstand zu einer Realisierung eines Werks? Welche Bedingungen müssen erfüllt sein, damit etwas eine Realisierung eines gegebenen Werks ist? Neben dem Begriff des Werks beruht die in dieser Arbeit entwickelte Theorie auf drei weiteren Grundbegriffen: Realisierungen, Konkretisierungen und Aktualisierungen. Realisierungen sind jene Gegenstände, in denen Werke realisiert sind. Konkretisierungen sind abstrakte Gegenstände, die durch "Vervollständigung" aus Werken hervorgehen. Sie sind immer noch unvollständig bestimmt, aber vollständiger bestimmt als die Werke, deren Konkretisierungen sie sind. Beispiele für Konkretisierungen sind Inszenierungen im Theater oder musikalische Interpretationen. Aktualisierungen sind die intentionalen Korrelate von Rezeptionsvorgängen. Sie entstehen im Verlauf der Rezeption eines Werks und werden von den Rezipienten erzeugt. Ein und dasselbe Werk kann auf verschiedene Weisen aktualisiert werden (z. B.: ein Musikstück kann auf verschiedene Weisen "gehört" werden). In eigenen Kapiteln werden Probleme der Mereologie, der Identität, des Darstellens und der Beziehung zwischen dem darstellenden Werk und dem Dargestellten erörtert. (shrink)

Si celebramos hoy, 19 de noviembre, el Día Mundial de la Filosofía, es porque consideramos que la Filosofía es una especie de patrimonio de la humanidad ¿verdad? Pero ¿qué hay en la filosofía que la haga merecedora de este calificativo? Para indagar en algunas de las razones que justifican este nombramiento de la UNESCO (...).

En su ópera prima, antes de concebir la filosofía crítica, Kant manifestó su entusiasmo por una geometría de todos los tipos posibles de espacio, y no sólo del espacio conocido. Como el filósofo atribuye cada espacio a un mundo posible distinto, la "geometría suprema", como la denominó, en realidad sería el nombre genérico para un conjunto de geometrías diversas que describen espacios igualmente diversos. En ese conjunto genérico se encuentra la geometría de Euclides, y cabe preguntarse si acaso entre las (...) otras especies no podrían hallarse las geometrías que hoy conocemos como no-euclídeas. Creemos que no es así, y es lo que nos proponemos mostrar en este trabajo. Sostendremos, por lo tanto, la distinción entre las denominaciones "otras geometrías" y "geometrías no-euclídeas" y desarrollaremos la incompatibilidad entre ambas tal como ésta se sigue de los textos de Kant. Intentaremos asimismo caracterizar las "otras geometrías" según la noción de "espacio habitado", por nosotros o por los eventuales habitantes de otros universos posibles. Así, las "otras geometrías" quizá podrían ser comprendidas mejor como geometrías de los otros (de la alteridad), que como anticipación de las geometrías no-euclídeas. (shrink)

Benito Pérez Galdós encontró en la clase media una fuente de inspiración para la creación de una novela de costumbres con una destacada dimensión política: describir y hacer comprensibles los problemas de índole moral que hacían muy difícil concebir e implantar un orden social basado en la prosperidad individual y colectiva. Aunque su talante descriptivo, su técnica realista, costumbrista e incluso naturalista, como se ha dicho en alguna ocasión —sin que estemos aquí completamente de acuerdo con ello—,es una de las (...) más sobresalientes de las letras españolas, Galdós nunca renunció al uso de una poderosa voz narrativa con la que imprimió a su literatura un declarado afán de comprensión de la realidad social.

En este artículo se analiza el planteamiento de Reinhart Koselleck en torno a la Begriffsgeschichte desde el punto de vista de la productividad de la historia, el tiempo y la productividad propia de la dialéctica de los conceptos. Para ello se traen a colación aspectos muy precisos de la filosofía de Aristóteles, Hegel y Gadamer. La reflexión concluye extrayendo algunas aportaciones que podrían enriquecer la investigación de Koselleck.

On March 27, 1572 Fray Luis de Leon was imprisoned, among other reasons, because according to his informers, fray Luis, in addition to «be a friend of novelties» has argued that to understand the Sacred Scripture is not necessary the scholastic Theology. Fray Luis, who was always opposed to this view, will try to defend himself on the basis of the work De doctrina christiana of St.Augustine and putting forward that to correctly interpret Scripture is necessary the scholastic Theology, but (...) also other wisdoms such as history or language knowledge.

The relationship between the necessity to ensure that information is shared in the stages of deliberation and the overcoming of what Dryzek (2001) called constriction of deliberative economy is directly related to the proponents and opponents’ propensity to submit and add information differently, in a plural manner. This article describes the salient features of the deliberative turn in order to defend that this propensity is not individual. The evolution of the public space in science and in politics are both paradigmatic (...) examples to appreciate that individual deliberation, and even mere aggregation of opinions, are consistently interpreted only if they are part of social practices and collective institutions aimed at defending tolerance towards positions, beliefs and interpretations that are different or even confronted. This paper argues that the so called model of contestatory deliberative democracy contributes to the acquisition of knowledge precisely because it fosters a plurality of epistemic states associated with practices as consensus and dissent.
