About one third of patients with epilepsy have seizures refractory to the medical treatment. Electrical stimulation mapping is the gold standard for the identification of “eloquent” areas prior to resection of epileptogenic tissue. However, it is time-consuming and may cause undesired side effects. Broadband gamma activity recorded with extraoperative electrocorticography during cognitive tasks may be an alternative to ESM but until now has not proven of definitive clinical value. Considering their role in cognition, the alpha and beta bands could further (...) improve the identification of eloquent cortex. We compared gamma, alpha and beta activity, and their combinations for the identification of eloquent cortical areas defined by ESM. Ten patients with intractable focal epilepsy participated in a delayed-match-to-sample task, where syllable sounds were compared to visually presented letters. We used a generalized linear model approach to find the optimal weighting of each band for predicting ESM-defined categories and estimated the diagnostic ability by calculating the area under the receiver operating characteristic curve. Gamma activity increased more in eloquent than in non-eloquent areas, whereas alpha and beta power decreased more in eloquent areas. Diagnostic ability of each band was close to 0.7 for all bands but depended on multiple factors including the time period of the cognitive task, the location of the electrodes and the patient’s degree of attention to the stimulus. We show that diagnostic ability can be increased by 3–5% by combining gamma and alpha and by 7.5–11% when gamma and beta were combined. We then show how ECoG power modulation from cognitive testing can be used to map the probability of eloquence in individual patients and how this probability map can be used in clinical settings to optimize ESM planning. We conclude that the combination of gamma and beta power modulation during cognitive testing can contribute to the identification of eloquent areas prior to ESM in patients with refractory focal epilepsy.

Using only propositional connectives and the provability predicate of a Σ1-sound theory T containing Peano Arithmetic we define recursively enumerable relations that are complete for specific natural classes of relations, as the class of all r. e. relations, and the class of all strict partial orders. We apply these results to give representations of these classes in T by means of formulas.

The aim of this paper is to argue that logic can play an important role in the “toolbox” of molecular biology. We show how biochemical pathways, i.e., transitions from a molecular aggregate to another molecular aggregate, can be viewed as deductive processes. In particular, our logical approach to molecular biology — developed in the form of a natural deduction system — is centered on the notion of Curry-Howard isomorphism, a cornerstone in nineteenth-century proof-theory.

In Aristotle's ethics and anthropology the concept of normality or regularity, nature and norm subtly imply each other reciprocally. The ethical criterium, explored throughout Nicomachean Ethics is that illustrated in detail by the "normal" conduct of the so called spoudaios. The point of contact between normality and naturalness is on the other side offered by the concept of physis, analysed both in Physics and in the biological works. Nature is what happens for the most, i.e. within the field of regularity (...) and legality which characterises its processes. But nature at the same time means telos, i.e. the finality and completion of these processes. What is normal is therefore also natural, and what is natural represents the normative level of phenomena. As for the ethical and anthropological field, the normal-natural human condition, and therefore the law which defines man's perfection, can be traced in the human political nature, i.e. in man's complete adjustment to the model given by the spoudaios. What falls outside this virtuous circle of normality, naturalness and legality is considered a moral deviation, which at the same time constitutes a teratology for and of mankind. Accordingly, conformity to the naturalized public ethos excludes in Aristotle any recourse to the transcendental norm of the "ought to be" which had been one of the fundamental characteristics of Plato's ethics.

Desde finales del siglo XX, las investigaciones sobre modernidad, orientadas hacia distintos segmentos del campo cultural, han venido ganando un enorme terreno. Las obras de Walter Benjamin, leídas en esta perspectiva, cobran un gran valor. Se busca explorar cuatro temas benjaminianos: a) algunos aspectos de su concepto de historia; b) el concepto de experiencia, para mostrar su dimensión histórico-crítica con respecto al ascenso de la cultura moderna; c) las afinidades entre el modo en que se desarrolla la visión alegórica en (...) el drama barroco alemán y el modo en que Baudelaire afronta las problemáticas de la modernidad; d) elementos de algunas formas culturales del arte moderno que entusiasman a Benjamin. Since the end of the 20th century, there has been increasing research on modernity, especially on different segments of the cultural field. Read in this context, the works of Walter Benjamin acquire great value.

Porté par la pensée structurante de Pierre Teilhard de Chardin, ce livre rassemble un ensemble de textes tirés d'auteurs multiples.

In this paper we argue that the formalisms for decoherence originally devised to deal just with closed or open systems can be subsumed under a general conceptual framework, in such a way that they cooperate in the understanding of the same physical phenomenon. This new perspective dissolves certain conceptual difficulties of the einselection program but, at the same time, shows that the openness of the quantum system is not the essential ingredient for decoherence. †To contact the authors, please write to: (...)

Talvez “redescobrimento” seja uma caracterização adequada para designar o _status_ do movimento neokantiano atualmente. Se, por um lado, o neokantismo tem recebido uma maior atenção em diversos lugares da Europa, América do norte, Ásia, e em alguns países da América Latina, por outro, na ainda jovem cultura filosófica brasileira, o estudo desse importante e decisivo movimento é algo atípico dentro de nossas instituições de ensino, para dizer o mínimo. De fato, a quantidade de trabalhos acadêmicos, artigos e livros sobre as (...) filosofias de autores como Cassirer, Windelband, Cohen, Lask, Natorp, Rickert e tantos outros que fizeram parte desse plural movimento filosófico está muito aquém do que eles realmente merecem. Sem dúvidas, esse “acerto de contas” com tais personagens seria uma tarefa muito mais árdua se não tivéssemos à nossa disposição os _Estudos_ _Neokantianos_, do Professor Mario Ariel González Porta.

Nel presente testo si propone un approccio alla neuroetica che si prefigge di attribuirle uno specifico ambito d’indagine in quanto esplorazione di ciò che apprendiamo su noi stessi e sul nostro “funzionamento”, grazie principalmente alle neuroscienze. In altre parole, si tratta di un nuovo genere di antropologia che si occupa dell’intersezione di diverse discipline la quale acquista sempre maggiore centralità nel dibattito contemporaneo a motivo della forte naturalizzazione delle indagini sugli esseri umani. L’oggetto di studio – alla luce di questa (...) particolare caratterizzazione della neuroetica – non sarà quindi ciò che possiamo fare, bensì ciò che sappiamo o riteniamo di sapere in modo affidabile.

In a recent paper, under the auspices of an unorthodox variety of bilateralism, we introduced a new kind of proof-theoretic semantics for the base modal logic \(\mathbf{K}\), whose values lie in the closed interval \([0,1]\) of rational numbers [14]. In this paper, after clarifying our conception of bilateralism – dubbed “soft bilateralism” – we generalize the fractional method to encompass extensions and weakenings of \(\mathbf{K}\). Specifically, we introduce well-behaved hypersequent calculi for the deontic logic \(\mathbf{D}\) and the non-normal modal logics (...) \(\mathbf{E}\) and \(\mathbf{M}\) and thoroughly investigate their structural properties.

Unfounded—conspiracy and health—beliefs about COVID-19 have accompanied the pandemic worldwide. Here, we examined cross-nationally the structure and correlates of these beliefs with an 8-item scale, using a multigroup confirmatory factor analysis. We obtained a two-factor model of unfounded (conspiracy and health) beliefs with good internal structure (average CFI = 0.98, RMSEA = 0.05, SRMR = 0.04), but a high correlation between the two factors (average latent factor correlation = 0.57). This model was replicable across 50 countries (total N = 13,579), (...) as evidenced by metric invariance between countries (CFI = 0.96, RMSEA = 0.06, SRMS = 0.07) as well as scalar invariance across genders (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03) and educational levels (CFI = 0.98, RMSEA = 0.04, SRMS = 0.03). Also, lower levels of education, more fear of COVID-19, and more cynicism were weakly associated with stronger conspiracy and health beliefs. The study contributes to knowledge about the structure of unfounded beliefs, and reveals the potential relevance of affective (i.e., fear of COVID-19) and cognitive (i.e., cynicism) factors along with demographics, in endorsing such beliefs. In summary, we obtained cross-cultural evidence for the distinctiveness of unfounded conspiracy and health beliefs about COVID-19 in terms of their structure and correlates. (shrink)

Insbesondere die Tragfähigkeit des transzendentalen Idealismus für Kants Metaphysik der Natur sowie die Schlüssigkeit seiner Moralphilosophie stehen in den Beiträgen des Bandes erneut auf dem Prüfstand. Zentrale Konzepte von Kants Transzendental- und Moralphilosophie, wie Substanz, Zeit, Freiheit und der kategorische Imperativ, werdenvor dem Hintergrund der Frage behandelt, wo Kant im Spannungsfeld zwischen traditionellem und modernem Wissenschaftsverständnis zu verorten ist. Bedeutende Vertreter der Kantforschung (u.a. H. E. Allison, P. Guyer, D. Schönecker, M.Caimi, H. Schmitz) liefern im vorliegenden Band Klärungen: Sie ordnen (...) Kant in den Kontext der Tradition und der zeitgenössischen Diskussion ein und ziehen produktive Vergleiche mit Autoren nach Kant, die sich kritisch mit ihm auseinander setzten. Der Band richtet sich an fortgeschrittene Studierende und Kantforscher, die sich einen repräsentativen Überblick über den aktuellen Stand der Debatte verschaffen wollen. (shrink)

Nella seconda metà del Novecento la conoscenza dell'etica anglosassone in Italia è stata alquanto parziale. Si pensava che il mondo dell'etica di lingua inglese fosse stato dominato nel Novecento dallo scientismo neopositivista o pragmatista che non riusciva a concepire l'etica se non nella forma tecnicizzata dell'analisi del linguaggio o metaetica. In questo modo si è ignorata tutta una ripresa dell'etica normativa, in particolare di Kant e di Aristotele, o la ripresa del diritto naturale che ha tra i suoi principali riferimenti (...) storici il pensiero di Tommaso d'Aquino intorno alla legge. Questo volume presenta un quadro della filosofia pratica anglosassone degli ultimi cinquant'anni. (shrink)

A dialog between Donald MacKay and Mario Bunge, printed in the journal Neuroscience over the course of two years beginning in 1977, provides a conscise summary of MacKay's views on the mind-body relationship. In this dialog, MacKay contrasts the dualistic interactionism theory of Popper and Eccles with Bunge's emergentist materialism theory, and then builds a case for a third alternative based on the notion of mental events embodied in, but not identical to, brain events. Although neuroscience has made tremendous (...) progress in the past two decades, MacKay's attempt to trace a path between interactionism and materialism is still worth considering. (shrink)

This volume collects essays by philosophers and scholars working at the interface of Western philosophy and Buddhist Studies. Many have distinguished scholarly records in Western philosophy, with expertise in analytic philosophy and logic, as well as deep interest in Buddhist philosophy. Others have distinguished scholarly records in Buddhist Studies with strong interests in analytic philosophy and logic. All are committed to the enterprise of cross-cultural philosophy and to bringing the insights and techniques of each tradition to bear in order to (...) illuminate problems and ideas of the other. These essays address a broad range of topics in the philosophy of mind, philosophy of language, logic, epistemology, and metaphysics, and demonstrate the fecundity of the interaction between the Buddhist and Western philosophical and logical traditions.

The work of the lay Catholic philosopher Jacques Maritain continues to provoke and inspire readers to engage in a Thomistic approach to many of the questions facing the world today. Maritain’s wide-ranging thought touched on many fields, including aesthetics, anthropology, educational theory, moral philosophy, and ethics, as well as Thomism and its relationship to other philosophical stances._ In _Being in the World: A Quotable Maritain Reader_, Mario O. D’Souza, C.S.B., has selected seven hundred and fifty of the most salient (...) quotations found in the English translations of fifty-four works by Jacques Maritain. Organized into forty thematic chapters, ordered alphabetically, the book serves as an overview of the areas that Maritain's writings addressed. By referring to entries in _Being in the World_, readers can quickly locate key passages in Maritain’s writing on a given topic and then turn elsewhere to the full texts for more in-depth study. Complete with a detailed index of key terms, the _Reader _will be an essential reference tool for the study of Maritain in English. "Fr. Mario O. D'Souza's careful selection from the works of Jacques Maritain provides the reader with an invaluable sampling of Maritain's extensive philosophical work. In it, we find examples of Maritain's almost lyrical gift of expression as well as of his trenchant wit. More than a scholarly contribution, the volume also ably serves as an introduction and entrance into Maritain's corpus." — William Sweet, St. Francis Xavier University, Canada_. (shrink)

Today’s pluralist and multicultural society raises questions about how to teach religiously and ethnically diverse students in Catholic schools. A Catholic Philosophy of Education addresses these challenges by examining the documents from the Roman Congregation for Catholic Education alongside the writings of Jacques Maritain and Bernard Lonergan. Mario D’Souza proposes a contemporary formulation for a Catholic philosophy of education in which the ideals of Catholicism form the basis for the mission of the Catholic school. Drawing on the Church’s educational (...) documents, and informed by Maritain and Lonergan, D’Souza explains how the unifying anthropology of Catholic education enables Catholic schools to serve amidst diversity by avoiding the extremes of religious exclusivism and fundamentalism, on the one hand, and relativism and individualism, on the other. He explores the aims of Catholic schools in relation to students, teachers, and society, and the relationship between goodness, discipline, and knowledge. He argues that students must be educated for personal and communal freedom and authenticity, and to strive for the common good, suggesting how a Catholic philosophy of education can provide the framework for such personal and communal transformation. Essential reading for new and experienced Catholic educators, A Catholic Philosophy of Education demonstrates that Maritain and Lonergan have much to offer in service of an education that is liberating, instructive, illuminating, and integrative.

Questions regarding what exists are central to various forms of Buddhist philosophy, as they are to many traditions of philosophy. Interestingly, there is perhaps a clearer consensus in Buddhist thought regarding what does not exist than there may be regarding precisely what does exist, at least insofar as the doctrine of anātman (no self, absence of self) is taken to be a fundamental Buddhist doctrine. It may be noted that many forms of Mahāyāna Buddhist philosophy in particular are considered to (...) offer a quite austere ontology—a rather ‘empty’ account of what exists. Continuing in this vein of ontological austerity, here I will attempt to lay out a relatively novel approach to Buddhist ontology, viz. Buddhist fictionalism. (shrink)

The paper points out that the modern formulation of Bohm’s quantum theory known as Bohmian mechanics is committed only to particles’ positions and a law of motion. We explain how this view can avoid the open questions that the traditional view faces according to which Bohm’s theory is committed to a wave-function that is a physical entity over and above the particles, although it is defined on configuration space instead of three-dimensional space. We then enquire into the status of the (...) law of motion, elaborating on how the main philosophical options to ground a law of motion, namely Humeanism and dispositionalism, can be applied to Bohmian mechanics. In conclusion, we sketch out how these options apply to primitive ontology approaches to quantum mechanics in general. (shrink)
