In the context of a larger project whose purpose was to comparatively analyze the associations of returnees in different autonomous communities, the need arose to specifically analyze the websites of these groups from a semiotic, discursive and communicational approach. The project required the creation of an analysis model based on a bibliographic review that would allow studying the sites in a comprehensive manner and that would take into account the new communicational paradigms. After exploring analysis models based on obsolete paradigms, (...) this research shows the design and validation of a website analysis proposal, in which two perspectives are differentiated and correlated: the technical aspects of the cyber genre and its discursive characteristics.

It is argued that if mainstream neoclassical economics is to be compatible with the health of both the social and natural environments, then it must dispense with a purely micro-level, individual treatment of the world through market dynamics and instead embrace a complementary treatment involving macro-level, collective boundary constraints of an ethico-social-biophysical character selecting what market dynamics are permissible. In this way, economics is transformed from mere dynamics to semiotics, in accord with von Neumann’s seminal work disclosing that life is (...) to be identified with the selective action of boundary constraints of a linguistic or semiotic nature.

Many phylogenetic systematists have criticized the Biological Species Concept (BSC) because it distorts evolutionary history. While defenses against this particular criticism have been attempted, I argue that these responses are unsuccessful. In addition, I argue that the source of this problem leads to previously unappreciated, and deeper, fatal objections. These objections to the BSC also straightforwardly apply to other species concepts that are not defined by genealogical history. What is missing from many previous discussions is the fact that the Tree (...) of Life, which represents phylogenetic history, is independent of our choice of species concept. Some species concepts are consistent with species having unique positions on the Tree while others, including the BSC, are not. Since representing history is of primary importance in evolutionary biology, these problems lead to the conclusion that the BSC, along with many other species concepts, are unacceptable. If species are to be taxa used in phylogenetic inferences, we need a history-based species concept. (shrink)

This paper aims to offer an account of affective experiences within Predictive Processing, a novel framework that considers the brain to be a dynamical, hierarchical, Bayesian hypothesis-testing mechanism. We begin by outlining a set of common features of affective experiences that a PP-theory should aim to explain: feelings are conscious, they have valence, they motivate behaviour, and they are intentional states with particular and formal objects. We then review existing theories of affective experiences within Predictive Processing and delineate two families (...) of theories: Interoceptive Inference Theories and Error Dynamics Theories. We highlight the strengths and shortcomings of each family of theories and develop a synthesis: the Affective Inference Theory. Affective Inference Theory claims that valence corresponds to the expected rate of prediction error reduction. In turn, the particular object of a feeling is the object predicted to be the most likely cause of expected changes in prediction error rate, and the formal object of a feeling is a predictive model of the expected changes in prediction error rate caused by a given particular object. Finally, our theory shows how affective experiences bias action selection, directing the organism towards allostasis and towards optimal levels of uncertainty in order to minimise prediction error over time.

Este artículo tiene un triple objeto: 1. Analizar, desde la perspectiva de la historia intelectual, el número extraordinario de Arbor (núm. 36, diciembre 1948) conmemorativo del cincuenta aniversario de 1898. 2. Valorar los cambios que se han producido, cincuenta años después, en nuestra perspectiva y conocimiento del «espíritu del 98». 3. Proponer algunas tareas prioritarias para la historia intelectual del periodo, a partir de la experiencia del trabajo realizado estos últimos años en la Residencia de Estudiantes. El número 36 de (...) Arbor reunió a un grupo de escritores bajo el liderazgo de Pedro Laín Entralgo: M. Fernández Almagro (historia), J. M.ª García Escudero (íd.), Gerardo Diego (poesía), Lafuente Ferrari (pintura), F. Sopeña (música), G. Bleiberg (revistas literarias), A. Gallego Morell (Ganivet), J. L. López Aranguren (Unamuno), G. Torrente Ballester (Hispanoamérica), H. Juretschke (crítica), J. L. Pinillos (bibliografía de Unamuno), J. M.ª Valverde (bibliografía de A. Machado), etc. En los apartados 2 y 3 del artículo se insiste especialmente en la necesidad de recurrir a las fuentes primarias y estudiar los fenómenos culturales en su contexto europeo. Se abordan los problemas existentes y las propuestas de trabajo en relación con las colecciones documentales, los planes de obras completas, las ediciones críticas, epistolarios, memorias, bibliografías, y los proyectos de seminarios y cursos pendientes.

Bertrand Russell dedicó parte de su obra a la discusión sobre el problema de la referencia y la descripción . Russell, junto Whitehead, elaboró un tratado de lógica matemática, titulado Principia Mathematica en el que retomó el proyecto de Frege tratando de demostrar que la matemática es una rama de la lógica. Russell no sólo tiene este propósito logicista, sino que también quiere concebir un lenguaje lógicamente perfecto , esto es, un lenguaje claro y preciso, en el que se elimina (...) toda ambigüedad y vaguedad. En una palabra el lenguaje de la ciencia. En este escrito desarrollaremos dicho propósito y veremos si tal lenguaje lógicamente perfecto es “aceptable” y conveniente en todos los contextos. (shrink)

A phylogeny that allows for lateral gene transfer (LGT) can be thought of as a strictly branching tree (all of whose branches are vertical) to which lateral branches have been added. Given that the goal of phylogenetics is to depict evolutionary history, we should look for the best supported phylogenetic network and not restrict ourselves to considering trees. However, the obvious extensions of popular tree-based methods such as maximum parsimony and maximum likelihood face a serious problem—if we judge networks by (...) fit to data alone, networks that have lateral branches will always fit the data at least as well as any network that restricts itself to vertical branches. This is analogous to the well-studied problem of overfitting data in the curve-fitting problem. Analogous problems often have analogous solutions and we propose to treat network inference as a case of model selection and use the Akaike Information Criterion (AIC). Strictly tree-like networks are more parsimonious than those that postulate lateral as well as vertical branches. This leads to the conclusion that we should not always infer LGT events whenever it would improve our fit-to-data, but should do so only when the improved fit is larger than the penalty for adding extra lateral branches.

There is a remarkable gap in the academic literature when it comes to group navigation, and procedural metacognition in group navigation is an important but virtually unexplored topic. The present paper aims to fill this gap by providing an account of how metacognitive feelings evaluate and regulate group navigational processes. The paper reviews animal studies and ethnographic work to elucidate three exiting processes in human group navigation: many-wrongs, leadership and emergent sensing. This is followed by an analysis of the role (...) of procedural metacognition in the navigational processes involved in each of these three processes. This analysis shows that procedural metacognition serves to regulate and evaluate group navigation in a flexible, process-specific way. When performance issues arise during group navigation, the emergence of negative affective states makes the navigational process conspicuous, prompting a modulation of said process. (shrink)

Eurípides se distingue entre los autores de tragedia por la habilidad con que transforma los estereotipos mitológicos en seres con una identidad personal concreta. Son distintas las estrategias a las que recurre con este fin. Una de ellas consiste en presentarlos a través de otros mostrando a la vez su actuación y sus condicionantes psicológicos; otro recurso que utiliza es dejar entrever el???? de los personajes en los discursos que pronuncian, así como sus capacidades retóricas. Una tercera técnica es la (...) de crear enfrentamientos entre dos parejas de personajes de las que uno es un dios y otro un mortal. En todas estas técnicas, que maneja con gran pericia retórica, hay siempre una idea que subyace y que sirve de filtro y de fondo de discusión. En el caso de Alcestis, la piedra de toque del???? es el?????, la ley o costumbre y la interpretación que de ella hacen los protagonistas. (shrink)

: This article presents a definition of action that links empirical facts with normative reasons to form an explanation of rational agency with predictive capabilities. This idea is developed along the lines of pragmatism which holds that a set of beliefs is a matter of linguistic evaluation from a particular community. This notion is related to the idea of facts as empirical information that is cognitively apprehended. Such information is regarded as an input which is later contrasted to expected behavioral (...) responses from the agent. The deviation of such observed behavior with respect to the expected one represents an evaluative output that is understood as the definition of reasonably expected behavior. Action is, thus, understood as the outcome of such an evaluative process. (shrink)

The article deals with the theories of the American philosopher John Searle concerning his embracement of a form of emergentism of the mind and his ideas about consciousness, intentionality with ‘C’, and language as a critique of traditional standpoints closer to positivist theses. Bearing this in mind, the general purpose is to reveal how the philosophy of Searle aims to recover the active role of the agent and, in consequence, the semantic and pragmatic dimensions of language are vindicated, dimensions in (...) which consciousness and intentionality are key to the construction and dynamism of social reality.

La migración internacional nos enfrenta con problemas irresolubles desde la figura moderna del Estado nacional, su concepto de ciudadanía y su noción de justicia. Juan Carlos Velasco critica las limitaciones y la orientación de las políticas contemporáneas que nos hacen percibir a la migración como una “invasión”, y propone un modo radicalmente diferente de entender e intervenir el fenómeno desde lo trasnacional. Nacer de uno u otro lado de una línea divisoria es un evento azaroso, no obstante delimitar la (...) frontera es una construcción histórico-política: la desigualdad en las oportunidades que ofrecen las naciones es una situación estructural de injusticia que se perpetúa con las políticas de exclusión de los migrantes y la deslegitimación de su derecho a buscar una vida mejor. Esa circunstancia genera fracturas sociales, injustificables pero normalizadas, que imposibilitan alcanzar la justicia global. Velasco presenta un análisis completo que abarca las dimensiones política, jurídica y moral del tema, en el que lleva a la filosofía política a un terreno práctico del que se desprenden las claves para entender y actuar en esta nueva era en la que, debido a los conflictos sociales y políticos, la migración vuelve a ser argumento de discusión relevante.

El artículo plantea la posibilidad de ofrecer acerca de los fenómenos y eventos mentales una concepción naturalista de análogo tenor a la que se ofrece de cualquier otro fenómeno físico o biológico. Aunque esto no supone pasar necesariamente por el reduccionismo, sí que constituye éste una de las posibilidades. En cualquier caso, la filosofía de la mente no puede ser prisionera de una tradición que exige un lugar separado y autónomo para la psicología del sentido común, y debe abrirse y (...) reconstruirse como filosofía de la ciencia, en cuyo ámbito los eventos mentales no pueden situarse en un nivel diferente del natural, porque ello supondría viciar de raíz el origen biológico de cualquier actividad humana, incluida la actividad mental. Dicho lo cual, es necesario aceptar que no se conoce todavía lo suficiente acerca del funcionamiento de las estructuras físico-cerebrales implicadas en la actividad cognitiva, pero éste parece ser, a pesar de todo, el camino más correcto.

Una de las principales aportaciones de la filosofía teórica kantiana es la tesis de que los seres humanos solo somos capaces de tener un conocimiento limitado del mundo. Una de las razones que llevaron a Kant a delimitar el conocimiento fue la consideración de otras posibles perspectivas desde las cuales conocer al universo, en particular, su creencia en la vida extraterrestre.

Civil disobedience is a widespread form of political protest used by minorities to make their voices heard in democratic societies. It is a mechanism of participation in the process of shaping public opinion, and of intervention, by via negativa, in the legislative process. In exercising it, citizens can assert their public autonomy when faced with serious decisions that, from their perspective, undermine the values on which society is based. This form of political dissidence is thus a highly valuable device in (...) order to revitalize the participatory fundamentals of representative democracy. Keywords: civil disobedience, representative democracy, political participation, citizenship, social change, Arendt, Habermas. (shrink)

: A pesar de los avances en materia de igualdad, todas las sociedades siguen estando organizadas jerárquicamente sobre la idea de la superioridad de lo masculino. Las mujeres continúan siendo conceptualizadas y representadas como inferiores y naturalmente distintas a los hombres. Las diferentes culturas están fundadas en la opresión real y simbólica de la población femenina. Esto atenta contra los principios de igualdad, libertad y justicia. Por lo tanto, la teoría feminista aspira a deconstruir los prejuicios inherentes a la sumisión (...) de las mujeres. El concepto de género aparece como una categoría analítica para contribuir a esta labor de deconstrucción. En el presente trabajo, se realiza un análisis crítico de este concepto, así como de las principales reflexiones filosóficas sobre el mismo, con el fin demostrar su relevancia en el estudio de la desigualdad y en la construcción de teorías emancipatorias.

A number of recent papers have criticized what they call the dynamical interpretation of evolutionary theory found in Elliott Sober’s The Nature of Selection. Sober argues that we can think of evolutionary theory as a theory of forces analogous to Newtonian mechanics. These critics argue that there are several important disanalogies between evolutionary and Newtonian forces: Unlike evolutionary forces, Newtonian forces can be considered in isolation, they have source laws, they compose causally in a straightforward way, and they are intermediate (...) causes in causal chains. Here we defend and extend the forces analogy by arguing that each of these criticisms is based on a misunderstanding of Newtonian forces. Our discussion also has the interesting consequence that natural selection turns out to be more similar to forces such as friction and elastic forces rather than the more canonical gravitation.

Studying disorientation is studying how, through our bodies, culture and technology, we humans are connected to our environment, and what happens when this connection is weakened or severed. What happens, of course, depends again on our environment, bodies, culture and technology: the world around us becomes at times uncanny, unfamiliar or dangerous when we get disoriented. Disorientation can be exciting and refreshing—an invitation to explore, to leave behind nagging desires for control and certainty, and to embrace instead a more spontaneous (...) relationship with our surroundings. Getting lost shapes our consciousness, not only by transforming our perception of the world around us, but by transforming our sense of who we are in that world, and what possibilities are open to us within it.In this chapter, we analyse the phenomenology of disorientation to elucidate the role that emotions play in distributed cognitive processes that involve multiple agents and cognitive artefacts. The feeling of disorientation destabilises our horizon of experience and turns the world around us unfamiliar or alien. This feeling embodies our disconnection to the agents, the cognitive artefacts, and the environment around us. A proper analysis of the phenomenology of both orientation and disorientation uncovers the role feelings play in distributed cognitive processes: emotions serve as a form of evaluative regulation that contributes to, on the one hand, the syncing of the different elements of a distributed cognitive process, and on the other, to the eventual disengagement of the agent from an unreliable distributed cognitive process.

Argumentar constituye un quehacer cotidiano para los diferentes operadores jurídicos y, de modo especial, para quienes desempeñan la función judicial. Dado que las decisiones de los jueces están sometidas a un cierto control de racionalidad, es posible concebir las argumentaciones jurídicas empleadas en la aplicación del derecho como un modo institucionalizado de ejercitar la racionalidad práctica. Sin embargo, esto no implica, en contra de lo que a menudo se suele afirmar, que los procesos argumentatívos jurídicos estén sujetos en exclusiva a (...) las leyes de la lógica deductiva. Cabe sostener el carácter racional de la aplicación del derecho sin caer en un logicísmo a ultranza ni en una defensa de las artes de la retórica y de la tópica: ahí está, entre otras, la vía defendida por la teoría discursiva de la argumentación jurídica elaborada por Robert Alexy a partir de presupuestos básicamente habermasianos, así como las correcciones contextualistas de la misma llevadas a cabo por Klaus Günthcr.
