Parménides es uno de los pensadores más influyentes de la filosofía occidental. El presente libro ofrece una hipótesis hermenéutica que se puede resumir en dos afirmaciones esenciales: primera, Parménides, como todos los pensadores de su tiempo, era ante todo un físico o fisiólogo (como los denominó Aristóteles), cuyas inquietudes y aportaciones se expresan en la segunda parte de su poema Sobre la naturaleza. Esa parte, escasamente representada en los fragmentos conservados, exponía una teoría original que se caracterizaba por defender una (...) física dualista frente al monismo de los milesios. Segunda, Parménides, a diferencia de la mayoría de los físicos, tomó conciencia por primera vez de la necesidad de explicar, no solo el orden de la naturaleza (physis) y las leyes que la rigen (tarea de los físicos), sino también el orden y las leyes del mundo del discurso (logos), de la teoría que trata de explicar el mundo. A esta segunda tarea, que sin duda puede ser calificada como el descubrimiento de la lógica, dedicó la primera parte de su Poema a modo de un discurso del método y no de una anacrónica especulación metafísica.

This paper aims to define the position of Protagoras on poetry, taking some crucial passages of Platonic Protagoras as texts that express the positions of the historical Protagoras. These passages, strictly incompatible with some essential theses of Plato’s thought, are the Great Speech (320c8-328d2), the intervention on the variety and variability of the good (334a3-c6) and the comment on the poem by Simonides (338e6-339d9). From these passages we can infer the position of the sophist towards poetry which could be summarized (...) in the following theses: 1. Poetry is an essential part of education. Epic poetry provides models for the education. Lyric poetry in turn helps to internalize in the souls of children the rhythm and the harmony that its verses contain. 2. However, an educated person should know how to evaluate what is right or wrong in the words of the poets. Criticism of Simonides’ poem is an example. From this perspective, the myth of Prometheus contained in the Protagoras Great Speech, which amends the versions of Hesiod and Aeschylus, can be considered as an model of poetic orthoepeia.

Tales de Mileto (VII–VI a.C.), además de ser uno de los siete Sabios, es considerado el primer filósofo precisamente por haber sido el primero en intentar dar razón de la estructura y formación del universo. El punto nuclear de la tesis de Tales afirmaba que el agua es el principio o materia originaria de la que han surgido todas las realidades que componen el variopinto y complejo tejido cósmico. A esta tesis, que hoy bien pudiera parecer extravagante, le cabe el (...) mérito y el privilegio de haber sido el motor que puso en movimiento un conjunto de inquietudes, de recursos y de métodos, de base racional, encaminados a dar respuesta a cuestiones que los seres humanos venían planteándose desde la misma noche de los tiempos. En qué medida y en qué sentido Tales de Mileto es deudor de creencias, instrumentos y saberes de su entorno (las ciudades griegas de las costas turcas del Egeo), incluidos los procedentes del este (Mesopotamia) y del Sur (Egipto), en qué medida fue Tales un innovador radical, son cuestiones que serán abordadas en este artículo.

Este artículo reflexiona sobre el interés y la importancia del pensamiento griego en relación con los problemas del presente y sugiere que es necesario analizar con sentido crítico los diversos procesos ideológicos que han interferido en la recepción de la filosofía griega en Occidente. Por otra parte, el autor señala las dos áreas del pensamiento griego que, en su opinión, tienen mayor interés para nuestro tiempo: la primera, la filosofía política y la recuperación de los pensadores de la democracia; y (...) la segunda, la tradición relativista que debería ser revisada con nuevos criterios.

El artículo analiza la noción griega de philía y describe dos enfoques diferentes, que se asocian respectivamente con Sócrates y Protágoras. Para el primero, la amistad, conectada con eros, es el lazo más importante entre los seres humanos, en tanto que para Protágoras ninguna relación, incluida la philía, puede estar por encima de justicia. La Medea de Eurípides sería una aplicación de la teoría de Protágoras a un caso célebre en la literatura mítica.

Objective: Loneliness is the subjective distress of feeling alone and has a strong impact on wellbeing and health. In addition to well-known predictors like isolation and poor health, a better understanding of the psychological determinants of loneliness would offer effective targets for future complementary interventions.Methods: In this cross-sectional observational study, we compared the explanatory power of several important risk factors of loneliness with the affective, motivational, and cognitive aspects of the Meaning in Life construct. Different nested linear models were compared (...) including socio-demographic, lifestyles, social-connectedness, and self-rated health variables, to assess the overlapping and non-overlapping explanatory power of each of them.Results: Health status and MiL were found to be the most important predictors of loneliness, followed by social connectedness and, with a much lower weight, lifestyles, and socio-demographic factors. Within the MiL factor, the most cognitive component, sense of coherence, had a greater explanatory power than the more affective and motivational ones.Conclusion: Reduced MiL, the capacity of an individual to attach “value and significance” to life, is a crucial predictor to the feeling of loneliness. These results suggest that programs aiming to combat loneliness should go well beyond situational interventions and include more cognitive, value-centered interventions that enable individuals to define and pursue a meaningful vital plan.

In recent years, supported by new scientific evidence, the conceptualization of cognitive reserve has been progressively enriched and now encompasses not only cognitive stimulating activities or educational level, but also lifestyle activities, such as leisure physical activity and socialization. In this context, there is increasing interest in understanding the role of psychological factors in brain health and cognitive functioning. In a previous study, we have found that these factors mediated the relationship between CR and self-reported cognitive functioning. In this study, (...) we have confirmed an association between two important constructs included in the psychological wellbeing and salutogenic models, “purpose in life” and “sense of coherence,” CR, as assessed using a questionnaire, and cognitive functioning, as evaluated using a comprehensive neuropsychological battery. Results from 888 middle-aged healthy participants from the Barcelona Brain Health Initiative indicate that both sense of coherence and CR were positively associated with verbal memory, reasoning and attention, working memory, and global cognition. Moreover, the relation between CR and cognitive functioning in the different domains is partially mediated by SoC. When we controlled for brain integrity, introducing into the model neurofilament light chain measures, the mediator role of SoC was confirmed for reasoning and attention and global cognition. However, purpose in life was not associated with cognitive functioning. These results reveal the central role of the SoC construct, which mediates the association between classic CR estimates and cognitive functions, potentially representing a modifiable target for interventions that aim to promote brain health.

Completa y exhaustiva monografía sobre la obra y el pensamiento de Edgar Morin desde la perspectiva de sus planteamientos antropológicos, relacionando éstos con algunos de los debates antropológicos actuales más relevantes.

Ambient assisted living technologies are increasingly presented and sold as essential smart additions to daily life and home environments that will radically transform the healthcare and wellness markets of the future. An ethical approach and a thorough understanding of all ethics in surveillance/monitoring architectures are therefore pressing. AAL poses many ethical challenges raising questions that will affect immediate acceptance and long-term usage. Furthermore, ethical issues emerge from social inequalities and their potential exacerbation by AAL, accentuating the existing access gap between (...) high-income countries and low and middle-income countries. Legal aspects mainly refer to the adherence to existing legal frameworks and cover issues related to product safety, data protection, cybersecurity, intellectual property, and access to data by public, private, and government bodies. Successful privacy-friendly AAL applications are needed, as the pressure to bring Internet of Things devices and ones equipped with artificial intelligence quickly to market cannot overlook the fact that the environments in which AAL will operate are mostly private. The social issues focus on the impact of AAL technologies before and after their adoption. Future AAL technologies need to consider all aspects of equality such as gender, race, age and social disadvantages and avoid increasing loneliness and isolation among, e.g. older and frail people. Finally, the current power asymmetries between the target and general populations should not be underestimated nor should the discrepant needs and motivations of the target group and those developing and deploying AAL systems. Whilst AAL technologies provide promising solutions for the health and social care challenges, they are not exempt from ethical, legal and social issues. A set of ELSI guidelines is needed to integrate these factors at the research and development stage. (shrink)

IntroductionExcitability of the primary motor cortex measured with TMS has been associated with cognitive dysfunctions in patient populations. However, only a few studies have explored this relationship in healthy adults, and even fewer have considered the role of biological sex.MethodsNinety-seven healthy middle-aged adults completed a TMS protocol and a neuropsychological assessment. Resting Motor Threshold and Long-Interval Intracortical Inhibition were assessed in the left motor cortex and related to attention, episodic memory, working memory, reasoning, and global cognition composite scores to evaluate (...) the relationship between cortical excitability and cognitive functioning.ResultsIn the whole sample, there was a significant association between LICI and cognition; specifically, higher motor inhibition was related to better working memory performance. When the sample was broken down by biological sex, LICI was only associated with working memory, reasoning, and global cognition in men. No associations were found between RMT and cognitive functions.ConclusionGreater intracortical inhibition, measured by LICI, could be a possible marker of working memory in healthy middle-aged adults, and biological sex plays a critical role in this association.

The paper deals with a version of the principle that a belief source can be a knowledge source only if the subject knows that it is reliable. I argue that the principle can be saved from the main objections that motivate its widespread rejection: the claim that it leads to skepticism, the claim that it forces us to accept counterintuitive knowledge ascriptions and the claim that it is incompatible with reliabilist accounts of knowledge. I argue that naturalist epistemologists should reject (...) these claims. I introduce my treatment of the principle by considering the analogous situation posed by the closure principle. (shrink)

Tarski's 1936 paper, “On the concept of logical consequence”, is a rather philosophical, non-technical paper that leaves room for conflicting interpretations. My purpose is to review some important issues that explicitly or implicitly constitute its themes. My discussion contains four sections: terminological and conceptual preliminaries, Tarski's definition of the concept of logical consequence, Tarski's discussion of omega-incomplete theories, and concluding remarks concerning the kind of conception that Tarski's definition was intended to explicate. The third section involves subsidiary issues, such as (...) Tarski's discussion concerning the distinction between material and formal consequence and the important question ofthe criterion for distinguishing between logical and non-logical terms.§1. Preliminaries. In this paper an argument is a two-part system composed of a set of propositions P and a single proposition c. The expression ‘c is a [logical] consequence of P’ is used with the same meaning as the expression ‘c is [logically] implied by P’. The expressions ‘is a logical consequence of’ and the converse ‘implies’ are relational. Often, I shall be talking in the same sense of validity of an argument. Validity is a property of arguments; an argument with premise-set P and conclusion c is valid if and only if P implies c; i.e., c is a logical consequence of P. Notice that this notion of argument is strictly ontic; it does not involve any agent that thinks, determines or establishes that a given proposition is or is not a consequence of a given set of propositions.

La historia personal y profesional de Carlos París discurre al hilo de la convulsa historia de España del último medio siglo, y la narra con una honestidad de la que muy pocos pueden hacer gala. Así, sin ira y sin tapujos, describe, por ejemplo, cómo pasó de una adhesión inicial a presupuestos falangistas a ser candidato del PCE, valorando cada etapa y cada motivo de cambio con un gran sentido crítico. Por su pluma desfilan también personajes fundamentales en la vida (...) española de los últimos cincuenta años con quienes Carlos París ha tenido una sólida relación, como Manuel Fraga, Javier Solana, Manuel Castells, Rosa Regàs, Ricardo de la Cierva, José Antonio Maravall, José María Valverde, Nicolás Sartorius y un largo etcétera. De la lectura de estas memorias se desprende, en fin, el retrato de una gran figura intelectual y humana que jamás se ha limitado a ser convidado de piedra ni en su país ni en el tiempo que le ha tocado vivir.Carlos París (Bilbao, 1925) es Catedrático Emérito de la Universidad Autónoma de Madrid, en la que fundó su Departamento de filosofía y de cuya Facultad de Filosofía y Letras fue elegido decano en las primeras elecciones. Es Doctor Honoris Causa por la Universidad de Valencia y ha sido Presidente de la Sociedad Española de Filosofía y del Ateneo Científico, Literario y Artístico de Madrid. Su obra ha sido objeto de diversos estudios y congresos internacionales, y recientemente se ha creado un Foro dedicado al análisis y difusión de su pensamiento. Hay que destacar, sobre todo, sus ensayos: Física y filosofía, 1952; Crítica de la civilización nuclear, 1985 o Fantasía y razón moderna-Don Quijote, Odiseo y Fausto, 2001, entre muchos otros; y también sus obras de creación literaria: la novela Bajo constelaciones burlonas (1981) o el libro de relatos La machina speculatrix-Cuatro sarcasmos sobre el mundo actual (1989).

In Wittgenstein on Rules and Private Language, Saul Kripke rejects some of the most popular accounts of what meaning facts consist in on the grounds that they fail to accommodate the normative character of meaning. I argue that a widespread interpretation of Kripke's argument is incorrect. I contend that the argument does not rest on the contrast between descriptive and normative facts, but on the thought that speakers' uses of linguistic expressions have to be justified. I suggest that the line (...) of reasoning that I attribute to Kripke can be seen as putting pressure on the idea that predicate satisfaction is to be explained in terms of a relation between predicates and properties.
