This work evaluated the structure of dreams in people affected by schizophrenia. The verbal reports of 123 schizophrenic patients were compared with 123 dream reports from a control group. In accordance with the Jungian conceptualization of, dreams as texts, dream reports were assessed using textual analysis processing techniques.Significant differences were found in textual parameters, showing that the dreams reports of schizophrenic patients differ from those of the control group. It is thus possible that schizophrenia probably underlies changes in the oneiric (...) production and dream reports. This work confirms the value of textual analysis in the study of oneiric material.

O artigo procura reconstruir a relação entre os pensadores francês e alemão, adotando o tema da história por fio condutor. A questão-chave concerne à possibilidade de elaborar-se uma história transcendental. Tal história, caso seja viável, constituirá uma historicidade, pois deverá descrever a gênese do sentido no intercâmbio necessário e incontornável entre as dimensões transcencendental e empírica. Como reduzir os vários fenômenos egóicos, temporais, intersubjetivos, etc. sem perder o âmbito empírico em que eles enraizam-se? Eis o principal desafio colocado pelos textos (...) derridianos à obra de Husserl. (shrink)

A common assumption in non-relativistic quantum mechanics is that self-adjoint operators mathematically represent properties of quantum systems. Focusing on spin, we argue that a natural view considers observables as determinable properties and their eigenvalues as their corresponding determinates. We provide a taxonomy of the different views that one can hold, once it is accepted that spin can be modelled with the determinable-determinate relation. In particular, we present the two main families of views, dubbed Spin Monism and Pluralism, and we show (...) that the current literature does not take a stance between the two. Then we put forward two arguments in favour of the former. Finally, we present a new account of Spin Monism, that is absent in current literature; such a view is worth discussing, or so we contend, because several compelling considerations support it, and it opens new ways of thinking about the ontology of quantum mechanics.

Baseado no cogito cartesiano, mas também o submetendo a importantes reformulações, Husserl desenvolve o seu próprio conceito de subjetividade transcendental. Tais reformulações concernem, sobretudo, aos tópicos do tempo, da redução e da intersubjetividade. O presente artigo pretende apresentar e discutir como se vinculam tais temas, visando a contribuir na compreensão do estatuto do transcendental na fenomenologia husserliana. PALAVRAS-CHAVE – Husserl. Subjetividade transcendental. Tempo. ABSTRACT Based on Cartesian cogito, but also submitting it to important reformations, Husserl develops his own concept of (...) transcendental subjectivity. These reformations concern especially the topics of time, reduction and intersubjectivity. This article intends to present and discuss the link of these themes, aiming contribute to the comprehension of the status of transcendental in husserlian phenomenology. KEY WORDS – Husserl. Transcendental subjectivity. Time. (shrink)

Assessing the scope of his own phenomenological project was always of philosophical concern to Husserl. Perhaps because of this, he has never ceased to reformulate his concepts and theories, aimed at an ever greater degree of depth. This interest by the limits of Husserlian phenomenology continues in the activity of his interpreters. This article intends to present and discuss some of these readings, trying to stress that the strategy of favouring ethical components to think the limits of Husserl’s phenomenology is (...) not a fruitful alternative. The discussion should favour ontological parameters, based in the approach of key concepts correctly selected, especially the concepts of infinite and living present. (shrink)

Learning the structure of event sequences is a ubiquitous problem in cognition and particularly in language. One possible solution is to learn a probabilistic generative model of sequences that allows making predictions about upcoming events. Though appealing from a neurobiological standpoint, this approach is typically not pursued in connectionist modeling. Here, we investigated a sequential version of the restricted Boltzmann machine, a stochastic recurrent neural network that extracts high-order structure from sensory data through unsupervised generative learning and can encode contextual (...) information in the form of internal, distributed representations. We assessed whether this type of network can extract the orthographic structure of English monosyllables by learning a generative model of the letter sequences forming a word training corpus. We show that the network learned an accurate probabilistic model of English graphotactics, which can be used to make predictions about the letter following a given context as well as to autonomously generate high-quality pseudowords. The model was compared to an extended version of simple recurrent networks, augmented with a stochastic process that allows autonomous generation of sequences, and to non-connectionist probabilistic models. We conclude that sequential RBMs and stochastic simple recurrent networks are promising candidates for modeling cognition in the temporal domain. (shrink)

Implanting deep brain stimulation (DBS) electrodes in patients with Parkinson’s disease often results in the appearance of a non-infectious, delayed-onset edema that disappears over time. However, the time window between the DBS electrode and DBS stimulating device implant is often used to record local field potentials (LFPs) which are used both to better understand basal ganglia pathophysiology and to improve DBS therapy. In this work, we investigated whether the presence of post-surgery edema correlates with the quality of LFP recordings in (...) eight patients with advanced Parkinson’s disease implanted with subthalamic DBS electrodes. The magnetic resonance scans of the brain after 8.5 ± 1.5 days from the implantation surgery were segmented and the peri-electrode edema volume was calculated for both brain hemispheres. We found a correlation (ρ = −0.81, p < 0.0218, Spearman’s correlation coefficient) between left side local field potentials of the low beta band (11–20 Hz) and the edema volume of the same side. No other significant differences between the hemispheres were found. Despite the limited sample size, our results suggest that the effect on LFPs may be related to the edema localization, thus indicating a mechanism involving brain networks instead of a simple change in the electrode-tissue interface.

Conviene subrayar en la época de la ciencia, cuando las prácticas más aberrantes y las especulaciones más desaforadas compiten por arrogarse el título de ciencias, que la filosofía no es una ciencia, ni necesita serlo para ejercer sus funciones críticas. No obstante, mantiene una relación íntima y constante con las ciencias desde sus orígenes hasta nuestros días (relación histórica), utiliza el mismo instrumento metodológico, la razón crítica (relación metódica) y recorre el mismo ámbito de la experiencia cognoscitiva humana (relación sistemática). (...) En ese sentido, la filosofía no se arredra ante el discurso postmoderno de la deslegitimación —Lyotard, Baudrillard, Vattimo, etc.—. Aunque las soluciones filosóficas son legitimadoras, no se reducen a mera ideología, ni tecnocrática ni progresista. (shrink)

En este texto discutiremos la tensión entre los nuevos medios y la narratología ocupándonos especialmente del caso del cine. Nuestra tesis será que los nuevos medios tienen que ver básicamente con la ilusión y solo derivadamente con la imaginación; por el contrario, el campo de la literatura tiene que ver solo con la imaginación y no con la ilusión. Si esto es así, algo debe estar mal con la pretensión de la narratología de ser el esquema teórico adecuado para entender (...) cualquier fenómeno cultural, especialmente el de losnuevos medios. Insistiremos, por ello, en la distinción entre ilusión e imaginación. De hecho, los teóricos literarios no lo consideran. Se suele decir que el cine es ficción, y de hecho la literatura es ficción, pero el cine es mucho más que la ficción, es una ilusión.Here we will discuss the tension between the new mass media and narratology and the case in study will be cinema. Our thesis would be that new mass media have to do basically with illusion and only derivatively with imagination; on the contrary, the field of literature has to do only with imagination, not with illusion at all. If it is so, something must be wrong with the pretence of narratology to be the adequate theoretical schema in order to understand every cultural phenomenon, especially in the case of new mass media. We have to insist on the distinction between illusion and imagination. In fact, literary theoreticians do mostly not consider it. It is usually said of cinema that it is fiction, and indeed literature is fiction, but cinema is much more than fiction, it is illusion. (shrink)

This paper aims to characterise properly entanglement as an external relation obtaining between multiple quantum degrees of freedom. In particular, we argue that the entanglement relation is a unique relation fully characterised by mutual information, i.e. a quantity standardly used as a measure of entanglement. This analysis leads us to propose a new metaphysical account of entanglement, which we call Relational Entanglement Tesseract. Such an account characterises entanglement for both bipartite and multipartite cases, and, at the same time, it satisfies (...) what we argue are three important desiderata of any metaphysical account of entanglement.

In this note, the problem of tracking random references and rejecting random perturbations in a quadrotor, both generated by an auxiliary system named exosystem, is solved by extending the deterministic tracking problem to the area of stochastic processes. Besides, it is considered that only a part of the state vector of the quadrotor is available through measurements. As a consequence, the state vector of the plant must be estimated in order to close the control loop. On this basis, a controller (...) to track random references and to reject random perturbations is developed by combining a Kalman filter to estimate the references and perturbations of an exosystem and an observer to estimate the states of a quadrotor. Besides, to obtain a more practical controller, the analysis is carried out in discrete time. Numerical simulations are used in a quadrotor to confirm the validity and effectiveness of the proposed control. (shrink)

Nella sua straordinaria opera scientifica, Franco Selleri si è sempre opposto alla rinuncia alla comprensione della struttura della realtà e della natura degli oggetti fisici, che egli considera come l’elemento caratterizzante delle principali teorie della fisica del Novecento e che è stata stigmatizzata da Karl Popper come tesi della “fine della strada in fisica”. Sin dalla fine degli anni ’60, egli ha sviluppato quella riflessione critica nei confronti delle teorie fondamentali della fisica moderna, in particolar modo della teoria delle particelle (...) elementari e della meccanica quantistica, e in un secondo tempo delle teorie relativistiche, che contraddistingue il suo programma di ricerca. Nel corso della sua intensa e infaticabile attività scientifica, Selleri è entrato in proficuo contatto con molti grandi fisici e filosofi della scienza, instaurando un intenso dialogo critico con Louis de Broglie, John Bell e Karl Popper. Le sue originali e non convenzionali ricerche lo hanno portato a risultati significativi non solo nell’ambito dei fondamenti della fisica, ma anche della storia e della filosofia della fisica. Per questo abbiamo voluto dedicare un numero speciale di Isonomia al nostro impareggiabile amico e collega, sia per la sua passione instancabile e la sua profonda conoscenza dei fondamenti formali, concettuali e filosofici delle teorie della fisica contemporanea, sia e forse ancor più come maestro di una prospettiva perennemente critica che egli ha sempre seguito e proposto con particolare rigore ed estrema determinazione.

This book builds on the idea that pragmatics and philosophy are strictly interconnected and that advances in one area will generate consequential advantages in the other area. The first part of the book, entitled ‘Theoretical Approaches to Philosophy of Language’, contains contributions by philosophers of language on connectives, intensional contexts, demonstratives, subsententials, and implicit indirect reports. The second part, ‘Pragmatics in Discourse’, presents contributions that are more empirically based or of a more applicative nature and that deal with the pragmatics (...) of discourse, argumentation, pragmatics and law, and context. The book presents perspectives which, generally, make most of the Gricean idea of the centrality of a speaker’s intention in attribution of meaning to utterances, whether one is interested in the level of sentence-like units or larger chunks of discourse.

IntroductionDuring the COVID-19 pandemic, healthcare workers in Italy have been exposed to an unprecedented pressure and traumatic events. However, no direct comparison with the general population is available so far. The aim of this study is to detail mental health outcomes in healthcare workers compared to the general population.Methods24050 respondents completed an on-line questionnaire during the contagion peak, 21342 general population, 1295 second-line healthcare workers, and 1411 front-line healthcare workers. Depressive, anxious, post-traumatic symptoms and insomnia were assessed. Specific COVID-19 related (...) potential risk factors were also considered in healthcare workers.ResultsDepressive symptoms were more frequent in the general population and front-line healthcare workers compared to the second-line healthcare workers groups. Anxiety symptoms showed a prevalence of 21.25% in the general population, 18.05% for second-line healthcare workers, and 20.55% for front-line healthcare workers. Insomnia showed a prevalence of 7.82, 6.58, and 9.92% for the general population, second-line healthcare workers, and front-line healthcare workers, respectively. Compared to the general population, front-line healthcare workers had higher odds of endorsing total trauma-related symptoms. Both second-line healthcare workers and front-line healthcare workers had higher odds of endorsing core post-traumatic symptoms compared to the general population, while second-line healthcare workers had lower odds of endorsing negative affect and dissociative symptoms. Higher total traumatic symptom score was associated with being a front-line healthcare worker, having a colleague infected, hospitalized, or deceased, being a nurse, female gender, and younger age.ConclusionThis study suggests a significant psychological impact of the COVID-19 pandemic on the Italian general population and healthcare workers. Front-line healthcare workers represent a specific at-risk population for post-traumatic symptoms. These findings underline the importance of monitoring and intervention strategies. (shrink)

The basic assumption present in these articles is that naturalism is highly compatible with a wide range of relevant philosophical questions and that, regardless of the classical problems faced by the naturalist, the price paid in endorsing naturalism is lower than that paid by essentialist or supernaturalist theories. Yet, the reader will find a variety of approaches, from naturalism in Moral Philosophy and Epistemology to naturalism in the Philosophy of Language, Philosophy of Mind and of the Aesthetics.

The epistemic, moral and political dimensions of Argentine anarchist writer Alberto Ghiraldo’s aesthetic discourse are examined here. This analysis is based upon his views of Jose Martí’s life and work as regards Ghiraldo’s attempt to edit the Cuban writer complete works ever since 1925. We hold Ghiraldo’s intent to give an epistemic and moralizing function to his writing tends to lose sight of the contingent forms of political articulation, and thus to dehistoricize practices on behalf benefit of the configuration (...) of an eschatological maximalism.

Dentro del marco de la teoría de los ensamblajes formulada por Manuel De Landa, en este artículo se desarrollan los siguientes puntos: el esclarecimiento del concepto de ensamblaje, la explicación de su carácter histórico y la problematización de esta teoría a partir de su relación con la epistemología, la ética y la ontología. En la conclusión, se clarifica el concepto de materia presupuesto en esta filosofía. Además, se muestra brevemente cómo esta ontología plana se vincula con la filosofía política (...) y, de nuevo, con la epistemología. Problematizar la teoría de los ensamblajes, cuya fuente filosófica se encuentra en la obra de Gilles Deleuze y Félix Guattari, permite reconocer los alcances de una ontología que postula la existencia de un mundo compuesto de multiplicidades históricas y heterogéneas.

This contribution explores in detail the presence and the context of two quotations of the philosopher and theologian Abū Ḥāmid al-Ġazālī (Algazel for the Latin world) in Albert the Great’s late Summa theologiae sive de mirabili scientia Dei. The two quotations, which concern the notion of the soul as “abridged letter” or “copy” [nusḫa muḫtaṣara, chartula brevis] on which all pieces of knowledge are potentially transcribed, occur in two significant textual points of Albert’s Summa. Two different aspects of al-Ġazālī’s simile (...) are addressed in the article: the consideration of the soul as a book, which has extremely wide biblical and literary echoes, and the consideration of the soul as a place, also with regard to the already Aristotelian, and then Albertinian notion of locus intelligibilium. The feature the two passages by Albert share is the acknowledgment of Algazel as a source of primary importance, capable of corroborating with his authority both a Christian theological doctrine and the littera itself of Aristotle’s De anima, in a culturally momentous philosophical-theological, and Islamic-Christian, cooperation. Thanks to a focused analysis on further contexts of reception of the same Ġazālīan image, which bear witness to its peculiar memorability and its differentiated usages, the article argues in conclusion in favour of a more attentive and in-depth study of philosophical similes such as the one here discussed.

Este artículo intenta articular la idea de una crítica de la razón armónica como un proyecto comprehensivo dentro del camino teórico de Kant. En la primera sección se aborda el intento de elaborar una idea crítica de la armonía tanto biográfica como teóricamente, en referencia al intenso periodo de 1783-1786. En la segunda sección, presento y discuto una idea metódica de armonía crítica, cuyas raíces están basadas en el marco del periodo pre-crítico y crítico. Finalmente, como presentación del editor (...) de este número monográfico, el trabajo inaugura el diálogo concerniente a la cuestión de la armonía con otros caminos interpretativos, ofreciendo una perspectiva comprehensiva de todos los trabajos reunidos en el número y organizando estos ricos materiales en torno a tres círculos concéntricos.

Es obligatorio comenzar reconociendo que la «identidad» es una palabra inevitable. Pero es que, nos guste o no nos guste, se ha puesto de moda la «búsqueda de la identidad» y su reafirmación como una suerte de propiedad esencial, en la que anida el alma o el genio de los pueblos. Está bien que se critique ese esencialismo identitario (y yo lo haré también con herramientas filosóficas), que se recuerde la naturaleza contingente de toda identificación, la historia cambiante que hace (...) de toda identidad un proceso, una realidad en perpetuo movimiento. Es cierto que este asunto se suele abordar en el marco de la globalización contra cuya supuesta uniformización y homogeneidad han surgido las respuestas identitarias de tipo étnico y cultural o la reafirmación de nacionalismos identitarios. Pero aquí no intentamos plantearlo en el abstracto plano de la geopolítica, sino en el muy concreto de la convivencia social. (shrink)

El objetivo del presente trabajo es explicar la relación entre las nociones de discurso y acción en un marco pragmático trascendental. El trabajo comienza con una presentación de la primera noción y de la idea de pretensión de validez. Luego son examinadas algunas objeciones a la justificación última de la ética, formulada por Apel. La conclusión es que es posible una respuesta a esas objeciones mediante la diferenciación entre dos niveles de la relación entre discurso y acción: un nivel (...) fáctico y uno trascendental. The aim of this paper is to explain the relation between the notions of discourse and action in a transcendental-pragmatic frame. The paper begins with a presentation of the first notion and the idea of validity claim. After that, some objections to Apel's ultimate justifications of ethic are examined. The conclusion is that an answer to these objections is possible throw the difference between two levels of the relation between discourse and action: a real level and a transcendental one. (shrink)

“Matrixes and Frames: Two Figures of Norm Functioning in the Work of Judith Butler”. The concepts of “intelligibility matrix” and “frame”, each corresponding to different periods in the thought of the feminist philosopher Judith Butler, seem to converge in so many aspects that one is tempted to hold that they may be used indistinctly. Nevertheless, the problem this paper deals with is the possible uniqueness the usage of the latter concept involves, thus pointing to the differences between both concepts. I (...) aim to solve the problem by studying the main sources that Butler herself uses in order to formulate the concept of frame, and by putting in evidence that which is gained by the use of that notion. I also aim to show more clearly the difference between the two concepts by appealing to their functions in the critique of speciffical cultural phenomenon: pornography as a frame and element of the heterosexual matrix.

El propósito de este trabajo es explicar la relación entre acción, reglas y discurso. El trabajo comienza con una presentación de algunas objeciones a la ética del discurso y su base común: la independencia entre moralidad y razón. Luego son propuestas contra esas objeciones dos tesis sobre la relación entre acción y discurso en un marco pragmático trascendental. La conclusión es que la posibilidad del discurso es una condición del sentido de la acción humana.
