Riassunto : Questo articolo propone un confronto tra la teoria mente-corpo di Henri Bergson e gli ultimi sviluppi della filosofia della mente e, più specificamente, con il cosiddetto “esternalismo”. Lo scopo è duplice. In primo luogo, si vuole sostenere che l’opera del filosofo francese ha anticipato i principali punti teorici dell’esternalismo: la teoria della percezione di Bergson, infatti, ha molti e rilevanti tratti in comune con la cosiddetta 4E Cognition, che finora non sono stati adeguatamente riconosciuti. In secondo luogo, l’articolo (...) intende anche mostrare come il quadro ontologico in cui Bergson colloca la propria interpretazione dell’esperienza cosciente, possa fungere da utile riferimento per il modello esternalista, al fine di sistematizzare i dati sperimentali entro un orizzonte teorico coerente. La teoria della "percezione pura" di Bergson, infatti, supera il modello correlazionista dell’esperienza, rilevando come quest’ultima, allo stato puro, si collochi nelle cose stesse, a un livello di realtà che precede la divaricazione dell’esperienza tra soggetto e oggetto, livello che deve essere pensato come l’origine impersonale della coscienza soggettiva. Parole chiave: Esternalismo; Percezione; Azione; Problema mente/corpo The mind/body problem in Henri Bergson e the externalism in philosophy of mind. Towards an ontological model: In this article we contrast Henri Bergson’s mind-body theory with the latest developments in Philosophy of Mind, more specifically, in so-called “Externalism”. This paper has two specific aims. First, we argue that the work of this French philosopher anticipated the main theoretical concepts of Externalism. Indeed, Bergson’s theory of perception shares many important features, which have not been adequately recognized until now, with so-called 4E Cognition. Second, we show how Bergson’s basic ontology, which frames his interpretation of conscious experience, could offer a coherent theoretical framework to systematize experimental data in an externalist model. Bergson’s theory of “pure perception” goes beyond correlation, showing that our experience, in its purest state, takes place within things themselves, at a level of reality that precedes the bifurcation of experience into a subject and an object. This undivided level of reality can be considered the impersonal origin of subjective consciousness. Keywords: Externalism; Perception; Action; Mind/Body Problem. (shrink)

A biography of Pedro Alfonso is proposed from the information today known. There is reproduced our mathematical deduction of the icon Trinitario of a parchment of Chartres of the XIIIth century from a figure precabalística introduced in 1110 by Pedro Alfonso of Huesca and it is presented three other materializations of the «alternated link of three rings any two not linked».

Può un’opera d’arte non avere proprietà estetiche? Può l’arte essere definita, e compresa, senza alcun riferimento all’estetico? Fino a qualche tempo fa, una riposta affermativa a queste due domande sembrava inevitabile: le cosiddette Teorie Estetiche dell’arte, per le quali le opere d’arte sono prodotte con l’intenzione di suscitare esperienze estetiche (soprattutto per il tramite delle proprietà estetiche), mostravano tutti i loro limiti di fronte alle nuove tendenze artistiche, come ad ese...

We examine ethical considerations in access to facial transplantation (FT), with implications for promoting health equity. As a form of vascularised composite allotransplantation, FT is still considered innovative with a relatively low volume of procedures performed to date by a small number of active FT programmes worldwide. However, as numbers continue to increase and institutions look to establish new FT programmes, we anticipate that attention will shift from feasibility towards ensuring the benefits of FT are equitably available to those in (...) need. This manuscript assesses barriers to care and their ethical implications across a number of considerations, with the intent of mapping various factors relating to health equity and fair access to FT. Evidence is drawn from an evolving clinical experience as well as published scholarship addressing several dimensions of access to FT. We also explore novel concerns that have yet to be mentioned in the literature. (shrink)

Cells are the fundamental building blocks of organisms and their organization holds the key to our understanding of the processes that control Development and Physiology as well as the mechanisms that underlie disease. Traditional methods of analysis of subcellular structure have relied on the purification of organelles and the painstaking biochemical description of their components. The arrival of high‐throughput genomic and, more significantly, proteomic technologies has opened hereto unforeseen possibilities for this task. Recently two reports(1,2) show how much can be (...) gleaned from the combination of analytical centrifugation, mass spectrometry and advanced statistical techniques focused on a high‐throughput analysis of the content and organization of plant and animal cells. The results reveal intriguing possibilities for the future and the possibility of mapping much of the known proteome onto our current map of the cell.

If Alfonso de Toledo's encyclopedia of knowledge is situated within the encyclopedic tradition, the Invencionario, 1474, is studied, highlighting the break it made with respect to the medieval order and its encyclopedias, a break which announced a new ordering of knowledge and which manifests a change of age: the transition from the Middle Ages to the Renaissance.

On propose une biographie de Petrus Alfonsi de Huesca. On reproduit notre déduction mathématique de l'icone Trinitaire d'un parchemin de Chartres, du Xlll siècle, depuis la figure précabalistique de Petrus Alfonsi, qu'il a introduit dans son oeuvre Dialogue contre les juifs en l'année 1110. On presente aussi trois matérialisations de I'enlacement alterné de trois anneaux deux à deux non enlacés.A Biography of Pedro Alfonso es proposed from the information today known. There is repruduced our mathematical deduction of the icon (...) Trinitario of a parchment of Chartres of the XIIIth century from a figure precabalistica introduced in 1110 by Pedro of Huesca and it is presented three other materializations of the "alternated link of three any two nost linked".

l. "Los axiomas de un sistema axiomático deben ser autoevidentes". ¿Cómo son, entonces, autoevidentes? ¿Qué ocurre si dijera: así es como lo encuentro mas fácil de imaginar. Y aquí imaginar no es un proceso mental particular en el cual uno cierra sus ojos o los cubre con las manos.

The aim of this work is to evaluate the role played by Alfonso Luis Herrera and Isaac Ochoterena in the institutionalization of academic biology in Mexico in the early 20th century. As biology became institutionalized in Mexico, Herrera's basic approach to biology was displaced by Isaac Ochoterena's professional goals due to the prevailing political conditions at the end of 1929. The conflict arose from two different conceptions of biology, because Herrera and Ochoterena had different discourses that were incommensurable, not (...) only linguistically speaking, but also socioprofessionally. They had different links to influential groups related to education, having distinct political and socioprofessional interests. The conflict between Herrrera and Ochoterena determined the way in which professional biology education has developed in Mexico, as well as the advancement in specific research subjects and the neglect of others.

Tommaso si e confrontato spesso con il tema del fine dell'uomo: ampie sezioni delle sue opere vi sono espressamente dedicate e altre ne sono l'implicita trattazione. La presente ricerca vuole introdursi all'opera di Tommaso d'Aquino non tanto evocando gli spettri di polemiche solo posteriori sul soprannaturale, quanto invece gettando uno sguardo al tempo in cui e vissuto, il XIII secolo, ed ad un luogo caratteristico nel quale egli ha studiato e insegnato: l'universita di Parigi. Ne viene fuori una figura in (...) profonda osmosi con le tensioni spirituali della sua epoca e preoccupato di esprimere la perennita della fede. Alfonso Valsecchi, 1971, ha conseguito licenza e dottorato presso la Pontificia Universita Gregoriana. (shrink)

Hannah Arendt’s work is an important reference for Paul Ricœur. Her definition of power as the free action in concert of individuals within a community of equals, guaranteed by institutions, allows Ricœur to ground his reflection on the political dimension of recognition and justice. However, as I will show in this paper, such a definition is problematic, particularly because of the relation that Arendt establishes between power and authority, her decision to separate the social and the political, and her understanding (...) of ideology, philosophy, and common sense in politics. After describing Arendt’s account of the relation between power and authority, I argue that, without rejecting the spirit of her political thought or her basic concepts, Ricœur’s reflections on the functions of ideology in his Lectures on Ideology and Utopia offer a broader but complementary vision that allows us to understand the issues that remain obscure in Arendt’s approach. -/- Résumé: L’œuvre de Hannah Arendt constitue une référence importante pour Paul Ricœur. La définition arendtienne du pouvoir comme agir ensemble des individus au sein d’une communauté d’égaux garantie par des institutions, fournit en effet à Ricœur les bases de sa réflexion sur la dimension politique de la reconnaissance et de la justice. Cependant, cet article s’efforce de montrer qu’une telle définition est problématique, non seulement en raison de la relation qu’Arendt établit entre le pouvoir et l’autorité, mais aussi en ce qui concerne sa distinction du social et du politique, sa compréhension de l’idéologie, ainsi que sa conception de la philosophie et du sens commun dans le domaine politique. Après une analyse des thèses d’Arendt sur la relation entre le pouvoir et l’autorité, cet article soutient que, sans rejeter l’esprit de la pensée politique arendtienne et ses concepts de base, la conception ricœurienne des fonctions de l’idéologie développée dans L’idéologie et l’utopie offre une vision plus ample et plus complète qui permet d’éclairer les questions qui demeurent obscures dans l’approche de Hannah Arendt.

IntroductionThe prefrontal cortex plays a crucial role in cognition, particularly in executive functions. Cortical reactivity measured with Transcranial Magnetic Stimulation combined with Electroencephalography is altered in pathological conditions, and it may also be a marker of cognitive status in middle-aged adults. In this study, we investigated the associations between cognitive measures and TMS evoked EEG reactivity and explored whether the effects of this relationship were related to neurofilament light chain levels, a marker of neuroaxonal damage.MethodsFifty two healthy middle-aged adults from (...) the Barcelona Brain Health Initiative cohort underwent TMS-EEG, a comprehensive neuropsychological assessment, and a blood test for NfL levels. Global and Local Mean-Field Power, two measures of cortical reactivity, were quantified after left prefrontal cortex stimulation, and cognition was set as the outcome of the regression analysis. The left inferior parietal lobe was used as a control stimulation condition.ResultsLocal reactivity was significantly associated with working memory and reasoning only after L-PFC stimulation. No associations were found between NfL and cognition. These specific associations were independent of the status of neuroaxonal damage indexed by the NfL biomarker and remained after adjusting for age, biological sex, and education.ConclusionOur results demonstrate that TMS evoked EEG reactivity at the L-PFC, but not the L-IPL, is related to the cognitive status of middle-aged individuals and independent of NfL levels, and may become a valuable biomarker of frontal lobe-associated cognitive function.
