Herculaneum papyri found during the discovery of the Villa dei Papiri in the XVIII century are our only knowledge about Greek philosophical schools. Unfortunately, the original manuscripts are in a precarious state of conservation and the currently available editions of them have largely been made obsolete by the latest technological progress. The aim of the Advanced Grant ERC project ‘Greekschools’ is to provide a new protocol based on optical methods to increase the text reading and thus allow for a new (...) critical edition of the whole treatise of Philodemus’ "Arrangement of the Philosophers". A multi-disciplinary approach is adopted and non-invasive techniques to Herculaneum papyri investigations such as Macro X-Ray Fluorescence Imaging (MA-XRF), Shortwave-Infrared Hyperspectral Imaging (SWIR), high resolution digital microscopy and Technical Photography were applied to read the text hidden on the verso, detect, classify, and replace overlapping layers and read the text concealed inside them. In this work some first preliminary results will be reported. (shrink)

In this study, we sought to assess the predictors of outcome in patients with disorders of consciousness (DOC) after severe traumatic brain injury (TBI) during neurorehabilitation stay. In total, 96 patients with DOC (vegetative state, minimally conscious state, or emergence from minimally conscious state) were enrolled (69 males; mean age 43.6 ± 20.8 years) and the improvement of the degree of disability, as assessed by the Disability Rating Scale, was considered the main outcome measure. To define the best predictor, a (...) series of demographical and clinical factors were modeled using a twofold approach: (1) logistic regression to evaluate a possible causal effect among variables; and (2) machine learning algorithms (ML), to define the best predictive model. Univariate analysis demonstrated that disability in DOC patients statistically decreased at the discharge with respect to admission. Genitourinary was the most frequent medical complication (MC) emerging during the neurorehabilitation period. The logistic model revealed that the total amount of MCs is a risk factor for lack of functional improvement. ML discloses that the most important prognostic factors are the respiratory and hepatic complications together with the presence of the upper gastrointestinal comorbidities. Our study provides new evidence on the most adverse short-term factors predicting a functional recovery in DOC patients after severe TBI. The occurrence of medical complications during neurorehabilitation stay should be considered to avoid poor outcomes. (shrink)

Au-dela des idees convenues, comment penser les fondements d'une crise sociale inscrite dans le temps long? La guerre civile perpetuelle evalue dans plusieurs domaines les ravages politiques de la philosophie de la modernite. Cette etude examine d'abord sa capacite a detruire a la racine la possibilite du lien social naturel, pour tenter par la suite de le recreer au moyen de divers artifices. Loin de se limiter au simple constat d'echec, l'originalite et la force de cet ouvrage resident dans l'analyse (...) des causes d'un processus logique qui tend a imposer sa violence intrinseque au coeur de la relation sociale.

Suppose that, yesterday at noon, Maria considered flipping a fair coin, but didn't. What probability do you assign to "If Maria had flipped the coin, the coin would have landed heads"? Now suppose that, contrary to fact, Maria did indeed flip the coin. In that counterfactual scenario, what is the probability of "The coin will land tails"? The two questions sound strikingly similar. I argue that they sound similar because they are equivalent. The chance of a counterfactual "If A, would (...) C" equals the chance of C, in the counterfactual scenario that A (and a similar principle holds for credence). This principle does better than similar principles that have been defended (like Skyrms' Thesis), avoids triviality, and gives us important clues for a semantics for counterfactuals. (shrink)

Some modal expressions in language—for example, "can" and "able'"—describe what is possible in light of someone's abilities. Ability modals are obviously related to other modalities in language, such as epistemic or deontic modality, but also give rise to anomalies that make them unique. This paper develops a general theory of ability modals that is broadly compatible with standard modal semantics, while predicting their peculiar behavior. The central idea is that ability modals include reference to a notion of dependence. At the (...) level of truth conditions, "S is able to A" simply says that there is a circumstantially accessible world where S As. On top of this, a not-at-issue element requires that whether S As depends, in part, on intrinsic features of S. Differently from most analyses, this account divorces ability modals from a notion of agency. (shrink)

This paper is about the alethic aspect of epistemic rationality. The most common approaches to this aspect are either normative (what a reasoner ought to/may believe?) or evaluative (how rational is a reasoner?), where the evaluative approaches are usually comparative (one reasoner is assessed compared to another). These approaches often present problems with blindspots. For example, ought a reasoner to believe a currently true blindspot? Is she permitted to? Consequently, these approaches often fail in describing a situation of alethic maximality, (...) where a reasoner fulfills all the alethic norms and could be used as a standard of rationality (as they are, in fact, used in some of these approaches). I propose a function α, which accepts a set of beliefs as inputand returns a numeric alethic value. Then I use this function to define a notion of alethic maximality that is satisfiable by finite reasoners (reasoners with cognitive limitations) and does not present problems with blindspots. Function α may also be used in alethic norms and evaluation methods (comparative and non-comparative) that may be applied to finite reasoners and do not present problems with blindspots. A result of this investigation isthat the project of providing purely alethic norms is defective. The use of function α also sheds light on important epistemological issues, such as the lottery and the preface paradoxes, and the principles of clutter avoidance and reflection. (shrink)

This paper investigates the concept of étendue intelligible, as used by Malebranche to frame a metaphysical theory on top of the concept of space, a new perspective on ideas and a solution to Cartesian issues about the nature of thought and its relationships with extension. In particular, attention is paid to the reasons why the étendue intelligible is, for Malebrance, the joining link between the human mind and God. Such a connection is emphasized not only for its metaphysical meaning but (...) also for the intrinsic relevance of a topological view of ideas. (shrink)

Reconociendo la insoslayable ambigüedad que afecta a la relación entre retórica y filosofía en la obra viquiana, este trabajo se preocupa por resaltar la continuidad entre el Vico retórico y el Vico filósofo, antes que por indagar las diferencias entre ambos. Semejante continuidad se percibe en la imaginación y en la persuasión. Ambos tópicos son tratados en profundidad en la Scienza Nuova, pero ponen de manifiesto consideraciones teóricas sobre la retórica que arrancan especialmente de las Institutiones Oratoriae.

Variations sur le survolRuyer, Merleau-Ponty, Deleuze et le statut de la formeLa question principale que j’aborde dans cet article concerne la manière dont Merleau-Ponty et Deleuze assument l’héritage du finalisme du vingtième siècle.En analysant certains textes fondamentaux de ces deux auteurs, on aperçoit en effet clairement leur dette à l’égard, notamment, du néo-finalisme de Raymond Ruyer. Autant Merleau-Ponty que Deleuze lisent l’oeuvre de Ruyer en la séparant de son contexte d’origine et de ses intentions explicites, à savoir hors de toute (...) exigence de nature épistémologique. Entre ces deux auteurs subsiste toutefois une différence substantielle dans la manière d’employer les concepts ruyériens. Merleau-Ponty réfute l’hypothèse d’une forme qui survole les matériaux constituant l’organisation idéale, mais valorise l’idée d’un thématisme immanent, d’une essence qui subsiste seulement à l’intérieur de ses variations. Deleuze, lui, semble reprendre sans réserve à son compte ces mêmes notions de forme et de survol parce qu’il les interprète comme des concepts plutôt que comme des causes formelles ou finales. Le concept deleuzien n’est pas pris dans la « pâte » du vécu, mais survole toute expérience vécue et tout état de choses. C’est pourquoi il ne peut être que créé, et c’est pourquoi la philosophie ne peut pas être uneactivité descriptive, à la manière de la phénoménologie, mais doit être nécessairement constructive.Variations on the SurveyRuyer, Merleau-Ponty, Deleuze and the Status of the FormThe main question that I confront in this article concerns the way in which Merleau-Ponty and Deleuze take up the heritage of 20th century finalism. By analyzing some of both of these authors’ basic texts, we clearly perceive their debt to, particularly, the neofinalism of Raymond Ruyer. Merleau-Ponty as much as Deleuze read Ruyer’s work separately from its original context and its explicit intentions, that is, they read it outside of any sort of epistemological demand. Nevertheless, we still find between the two a substantial difference in the manner of using Ruyer’s concepts. Merleau-Ponty refutes the hypothesis of a form that surveys the materials that constitute the ideal organization, but valorizes the idea of an immanent thematism, of an essence that only subsists within its variations. Deleuze, for his part, appears by contrast to take unreservedly into his own account these same notions of form and survey because he interprets them as concepts rather than formal and final causes. The Deleuzian concept is not “infested” with the lived, but surveys all lived experience and every state of things. That is why itcan only be created and that is why philosophy cannot be a descriptive activity, in the manner of phenomenology, but will necessarily be constructive. (shrink)

Quine is one of the most influential of contemporary philosophers, whose work has ranged broadly across a great number of topics and issues in a career spanning some fifty years. In this collection a group of distinguished philosophers offer a sustained critical evaluation of the full range of Quine's writings. Amongst the topics addressed are interpretation, epistemology, ontology, modality, and mathematical truth. This collection will certainly influence all future discussion of Quine. The contributors include: George Boolos, H-N. Castaneda, Donald Davidson, (...) Umberto Eco, Dagfinn Follesdal, James Higginbotham, Charles Parsons, Hilary Putnam, Barry Stroud, and Bas van Fraassen. However, Quine is given the last word, responding to the essays in the final contribution. (shrink)

In the Epistle to the Hebrews the terms σκιά and εἰκών are opposed, and most commentators have focused on the latter term, interpreting it as a Platonic allusion. If we consider in more detail the meanings of σκιά and σκιαγραφία, another interpretation appears more likely. Σκιαγραφία means “shading”, “silhouette” or “outline”, and finally “sketch” or – even better – “preliminary drawing”, “underdrawing”or “sinopia”. The last meaning is well attested in the sources at least since the late second or early third (...) century AD and a number of passages in the Fathers alluding to the Epistle support the same conclusion. The term is common in the technical terminology of painters on wooden tablets and was a widely employed topos with different nuances according to different authors. (shrink)

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: I contrast enactivist and ecological perspectives on some of the themes raised by the authors. I discuss some of their worries about the notion of sense-making and other epistemological aspects of enactivism.

The COVID-19 pandemic is an unprecedented event entailing long-term consequences on population health and welfare. Those who contracted the coronavirus may have suffered from both physical and mental health issues that unfold the need for tailored intervention strategies. Hence, our study aims to investigate the psychological and social consequences of COVID-19 on a sample of 86 participants, encompassing 43 patients recruited from Bari University Hospital, 19 of whom were hospitalized due to the disease. The remaining 43 were individuals not fallen (...) ill with COVID-19 to date. The investigation yielded significant gender differences in post-traumatic stress symptoms, depression, and representation of interpersonal distance, evaluated through the IES-R, the BDI-II, and the IVAS task, respectively. This pattern of results was not replicated in the control group. In general, participants who reported having experienced the most intense post-traumatic symptoms also presented a greater mood deflection and, more specifically, within the clinical group women obtained the highest scores on both scales. Women reported higher IES-R and BDI-II scores compared to men, that could indicate that women who have contracted COVID-19 are more exposed to post-traumatic and depressive symptoms. Our results also showed a significant effect of COVID-19 on IPD with a tendency of disease-experienced individuals to increase their preferred IPD from adults, children, and elderly people. Regarding gender differences in mood and proxemic behavior, a correlation between depressive symptoms and probable PTSD and a further correlation between probable PTSD and greater IPD were found in women from both clinical and control group. Overall, these findings might contribute to a better understanding of gender-based implications of the current pandemic on mental health, also leading to the development of integrated yet personalized intervention strategies.

Logical forgetting is NP-complete as a decision problem even in the simple case of propositional Horn formulae, and may exponentially increase their size. A way to forget is to replace each variable to forget with the body of each clause whose head is the variable. It takes polynomial time in the single-head case: each variable is the head of at most a clause. Some formulae are not single-head but can be made so to simplify forgetting. They are called single-head equivalent. (...) The first contribution of this article is the study of a semantical characterization of single-head equivalence. Two necessary conditions are given. They are sufficient when the formula is interequivalent, that is, the formula makes two sets of variables equivalent only if they are also equivalent to their intersection. All acyclic formulae are interequivalent. The second contribution of this article is an incomplete algorithm for turning a formula single-head. In case of success, forgetting becomes possible in polynomial time and produces a polynomial-size formula, none of which is otherwise guaranteed. The algorithm is complete on interequivalent formulae. (shrink)

Scientific literature on particular themes in ontology is extremely abundant, but it is often very hard for freshmen or sophomores to find a red thread between the various proposals. This text is an opinionated introduction, a preliminary text to research in ontology from the so called standard approach to ontological commitment, that is from the particular point of view that connects ontological questions to quantificational questions. It offers a survey of this viewpoint in ontology together with their possible applications through (...) a broad array of examples and open problems and, at the same time, essential references to the classics of philosophy, so as to allow non-specialists to understand the terms and analysis procedures characterizing the discipline. Its result is a wide-ranging overview of the issued tackled by ontology, with a particular focus on the most relevant problems of contemporary debate. (shrink)

All reasoners described in the most widespread models of a rational reasoner exhibit logical omniscience, which is impossible for finite reasoners (real reasoners). The most common strategy for dealing with the problem of logical omniscience is to interpret the models using a notion of beliefs different from explicit beliefs. For example, the models could be interpreted as describing the beliefs that the reasoner would hold if the reasoner were able reason indefinitely (stable beliefs). Then the models would describe maximum rationality, (...) which a finite reasoner can only approach in the limit of a reasoning sequence. This strategy has important consequences for epistemology. If a finite reasoner can only approach maximum rationality in the limit of a reasoning sequence, then the efficiency of reasoning is epistemically (and not only pragmatically) relevant. In this paper, I present an argument to this conclusion and discuss its consequences, as, for example, the vindication of the principle 'no rationality through brute-force'. (shrink)

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making diferent traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing—notably, the “sufcient-component-cause framework” and the “mark transmission” approach; (b) new acquisitions about disease pathogenesis, e.g. the “branched model” in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics (...) research, with a large number of “signals” and of associations that need to be interpreted. In the paper we summarize frst the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of “cancer causes”. We try to ofer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called “evidential pluralism”. According to this view, causal reasoning is based on both “evidence of diference-making” (e.g. associations) and on “evidence of underlying biological mechanisms”. We conceptualize the way scientists detect and trace signals in terms of information transmission, which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro-biological and psycho-social—are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level. (shrink)

The paper deals with three interrelated Pareto’s contributions to fiscal sociology of relevant contemporary importance, i. e., the maximum of utility of the community as a sociological process (Pareto II criterion of maximum welfare), the non logical actions consisting of derivations based on residuals and the theory of the elites. Pareto II welfare criterion of sociological maximization of individual utilities is compared with Pareto I welfare criterion, commonly known as Pareto criterion, introducing the process of valuations by the elite of (...) the utilities of different social groups weighed according to their residuals. Derivations are essentials to persuade the masses to move to the points designed by the elite. The process is subject to the law of circulation of the elites which leads to different sociological equilibriums. The theories of the elites of Pareto and Mosca, criticized by Einaudi, are then compared. For a disenchanted analysis of the fiscal processes and designs, Pareto’s sociology may still provide to the economist more than a help. (shrink)

God's character remains one of the big mysteries in Supernatural. We certainly see God's impact on the world, and occasionally, we're told he has miraculously interceded on behalf of the Winchesters or Castiel. Spinoza said, ”The knowledge of evil is an inadequate knowledge.“ But after concluding that God exists, Spinoza concludes that evil does not. Ironically, while many thought of Spinoza as the Devil, he denied the Devil's existence. As Supernatural illustrates, loving relationships don't need to be mutually beneficial; one (...) person may even risk his life to save another person he loves. Often philosophical, the ending scene may hold the key to understanding God in Supernatural. The Philosopher John Locke argued that the idea of redemption could be arrived at in principle by the same sort of reasoning that arrives at the idea of God. (shrink)
