Aristotelian philosophy is generally regarded as incompatible with the mathematical methods and principles that form the basis of modern science. This book offers an entirely new perspective on this presumed incompatibility. It surveys the tradition of the Oxford Calculators from its beginnings in the fourteenth century until Leibniz and the philosophy of the seventeenth century and explores how the Calculators' techniques of quantification expanded the conceptual and methodological limits of Aristotelianism. In the process, it examines a large number of authors, (...) some of them never studied in this context. Exploring the relationship between various late medieval disciplines, the book sheds new light on the problem of continuity vs. discontinuity between scholasticism and modern science. Beyond its historiographical purpose, this book also hopes to be a source of inspiration for present-day philosophers of science. Co-edited by Daniel A. Di Liscia and Edith D. Sylla with the collaboration of Paul Bakker. (shrink)

The following paper investigates the concept of motion in Jacques Legrand, a hitherto little-studied author of the early fifteenth century. Legrand, an important member of the Order of Hermits of Saint Augustine, wrote a philosophical Compendium for the students of his Order. This contribution first attempts to provide a contextualization of Legrand’s treatment of motion within this work. Legrand’s contribution to philosophical encyclopedism is here discussed. Secondly, it reviews the most important theories on the nature of movement in the Middle (...) Ages. Thirdly, it offers a detailed analysis of Legrand’s arguments in support of the nominalist view that it is unnecessary (if not wrong) to consider the local motion as a fluxus added to the moveable body. The article suggests that Legrand’s generalized nominalist position may be connected with certain lines to be followed within his own Order or even with the anti-realist ideology of the conciliarists philosopher, like Pierre D’Ailly and Jean Gerson.

Jaswal & Akhtar in their target article convincingly argue that subjects with autism do not have diminished social motivation. However, they still recognize that autistic people behave socially in an unusual way. Why? Here we suggest that these behaviours are the results of a multisensory integration deficit. Viewed from this perspective, the assumption that autistic people's unusual behaviours indicate diminished social motivation has to be replaced by the one that they have diminished social prediction skills.

Technologies like passive brain-computer interfaces can enhance human-machine interaction. Anyhow, there are still shortcomings in terms of easiness of use, reliability, and generalizability that prevent passive-BCI from entering real-life situations. The current work aimed to technologically and methodologically design a new gel-free passive-BCI system for out-of-the-lab employment. The choice of the water-based electrodes and the design of a new lightweight headset met the need for easy-to-wear, comfortable, and highly acceptable technology. The proposed system showed high reliability in both laboratory and (...) realistic settings, performing not significantly different from the gold standard based on gel electrodes. In both cases, the proposed system allowed effective discrimination between low and high levels of workload, vigilance, and stress even for high temporal resolution. Finally, the generalizability of the proposed system has been tested through a cross-task calibration. The system calibrated with the data recorded during the laboratory tasks was able to discriminate the targeted human factors during the realistic task reaching AUC values higher than 0.8 at 40 s of temporal resolution in case of vigilance and workload, and 20 s of temporal resolution for the stress monitoring. These results pave the way for ecologic use of the system, where calibration data of the realistic task are difficult to obtain. (shrink)

I saggi che compongono questo libro intendono presentare in maniera organica e interdisciplinare, anche se da una prospettiva fondazionale logico-filosofica, il ruolo che il concetto di prova svolge in differenti ambiti del sapere. L’elemento innovativo e caratterizzante del volume è quello di stabilire e formulare quali sono le condizioni di adeguatezza materiale e formale per una corretta esplicazione del concetto di prova nelle sue differenti applicazioni. Si cercherà, inoltre, di cogliere cosa ha qualificato storicamente e qualifica tuttora il concetto di (...) prova tentando di individuarne, da un lato, le caratteristiche persistenti o invarianti e, dall’altro, le differenze specifiche che esso assume in molteplici settori della ricerca. Vengono così presentati sette saggi che spaziano sui seguenti temi: dalle procedure logiche di prova medievali (Alfredo Di Giorgio), si va alla nozione di prova da Frege a Wittgenstein (Carlo Penco), al problema delle verità delle proposizioni gödeliane (Sergio Galvan), alla fondazione delle leggi logiche (Ciro De Florio), ai fondamenti del linguaggio pragmatico (Antonio Negro e Davide Sergio), alla relazione tra conoscibilità e prova (Massimiliano Carrara e Daniele Chiffi), fino all’analisi del paradosso del buon samaritano (Andrea Favaro e Silvia Gaio).

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.3 (2003) 414-415 [Access article in PDF] Gregorio Piaia, editor. La presenza dell'aristotelismo padovano nella filosofia della prima modernità: Atti del Colloquio internazionale in memoria di Charles B. Schmitt (Padova, 4-6 settembre 2000). Rome and Padua: Antenore, 2002. Pp. 488. Paper, € 38.00.Dedicated to the impact of Paduan Aristotelianism on early modern philosophy, this volume, edited by Gregorio Piaia, presents the proceedings of (...) a much-anticipated conference held in memory of Charles B. Schmitt at the University of Padua on September 4-6, 2000, jointly co-sponsored by Padua's Department of Philosophy, the Centro per la Storia dell'Università di Padova, the Seminar für Philosophie und Geistesgeschichte der Renaissance of the University of Munich, the Center for Medieval and Renaissance Natural Philosophy of the Catholic University of Nijmegen, and the Foundation for Intellectual History of London. It was indeed Schmitt's merit (one thinks first and foremost of The Cambridge History of Renaissance Philosophy he edited in 1988) to have revised in the most critical and convincing way the image historians of philosophy had of Renaissance Aristotelianism as a backward-looking movement unable to express any vitality, to say nothing about its influence on later philosophers. Obviously, the Paduan Aristotelians did not achieve the same impact as Descartes and they did not produce the sharp reactions the libertins provoked. Yet, their impact was substantial, as many contributors show, with a concentration in the north of central Europe, i.e., in Germany and in Scandinavia.The volume opens with a paper by Stefano Perfetti on the physician, statesman, and philosopher Giulio Cesare Scaligero, who belongs among the Paduan Aristotelians because he received his education at Padua. The works of the "pure Aristotelian" (following the definition of this movement provided by Wilhelm Risse) Giacomo Zabarella, surely the most celebrated of the group, is the subject of papers by Francesco Bottin, Ian McLean, Sachicko Kusukawa, Daniel A. Di Liscia, Heikki Mikkeli, Merio Scattola, David A. Lines, Antonino Poppi, Paul Richard Blum, Giovanna Varani, Gregorio Piaia, and Giuseppe Micheli. They have looked into the impact of Zabarella's philosophy, logic, and theory of demonstration (the celebrated regressus) in contexts such as Lutheran Germany and Scandinavia, Reformed Germany and Holland, and Catholic Italy and France during the impressive span from the publication of Melanchthon's Dialectic in 1520 to that of Kant's Critique of Judgment in 1790. Less known today, but quite influential until 1648, was the "eclectic Aristotelian" (to use Schmitt's phrase) and colleague (and antagonist) of Zabarella, Francesco Piccolomini, whom Jill Kraye, Heikki Mikkeli, Merio Scattola, and David A. Lines consider in their papers. Piccolomini became famous for his mediation between Aristotelianism and Platonism. He revived "the soul of Aristotle and the spirit of Plato," as a contemporary said. Pierre Bayle and Jakob Brucker highlighted Piccolomini's efforts to combine Aristotelian and Platonic philosophy; and modern scholars have identified many [End Page 414] Platonizing elements in his Aristotelianism. In the hope of producing a more accurate and complete picture of eclectic Aristotelianism within the context of Renaissance moral philosophy, Jill Kraye's paper explores a neglected side of Piccolomini's ethical thought, namely his careful account of Stoicism. Finally, a group of papers with a more general scope needs to be mentioned, namely Heinrich C. Kuhn's survey of works of Paduan Aristotelians in German libraries, Charles H. Lohr's paper on the sources of Calvinist theories of science, and Ekhard Kessler's paper on the relation of logic to hermeneutics. As a last remark, of the seventeen contributions to this important volume, which no research library should be without, eight are in Italian, six in English, and three in German.

We show that the complete first order theory of an MV algebra has equation image countable models unless the MV algebra is finitely valued. So, Vaught's Conjecture holds for all MV algebras except, possibly, for finitely valued ones. Additionally, we show that the complete theories of finitely valued MV algebras are equation image and that all ω-categorical complete theories of MV algebras are finitely axiomatizable and decidable. As a final result we prove that the free algebra on countably many generators (...) of any locally finite variety of MV algebras is ω-categorical. (shrink)

In [9] Mundici introduced a categorical equivalence Γ between the category of MV-algebras and the category of abelian [MATHEMATICAL SCRIPT SMALL L]-groups with strong unit. Using Mundici's functor Γ, in [8] the authors established an equivalence between the category of perfect MV-algebras and the category of abelian [MATHEMATICAL SCRIPT SMALL L]-groups. Aim of the present paper is to use the above functors to provide Yosida like representations of a large class of MV-algebras.

In this work we introduce a class of commutative rings whose defining condition is that its lattice of ideals, augmented with the ideal product, the semi-ring of ideals, is isomorphic to an MV-algebra. This class of rings coincides with the class of commutative rings which are direct sums of local Artinian chain rings with unit.

In this paper we show that the prime ideal space of an MV-algebra is the disjoint union of prime ideal spaces of suitable local MV-algebras. Some special classes of algebras are defined and their spaces are investigated. The space of minimal prime ideals is studied as well.

In this article we present an advanced version of Dual-PECCS, a cognitively-inspired knowledge representation and reasoning system aimed at extending the capabilities of artificial systems in conceptual categorization tasks. It combines different sorts of common-sense categorization (prototypical and exemplars-based categorization) with standard monotonic categorization procedures. These different types of inferential procedures are reconciled according to the tenets coming from the dual process theory of reasoning. On the other hand, from a representational perspective, the system relies on the hypothesis of conceptual (...) structures represented as heterogeneous proxytypes. Dual-PECCS has been experimentally assessed in a task of conceptual categorization where a target concept illustrated by a simple common-sense linguistic description had to be identified by resorting to a mix of categorization strategies, and its output has been compared to human responses. The obtained results suggest that our approach can be beneficial to improve the representational and reasoning conceptual capabilities of standard cognitive artificial systems, and –in addition– that it may be plausibly applied to different general computational models of cognition. The current version of the system, in fact, extends our previous work, in that Dual-PECCS is now integrated and tested into two cognitive architectures, ACT-R and CLARION, implementing different assumptions on the underlying invariant structures governing human cognition. Such integration allowed us to extend our previous evaluation. (shrink)

_Riassunto_: In questo articolo cercheremo di delineare le caratteristiche di una fenomenologia dell’attenzione incentrata sui concetti di interesse e selezione. Partiremo dall’analisi del concetto di attenzione in Husserl per poi concentrarci sulle riflessioni di William James, Alfred Schutz ed Erving Goffman che riconoscono un ruolo fondamentale dell’attenzione nei processi con cui gli attori sociali inquadrano e definiscono la realtà e, infine, analizzeremo la proposta teorica di Bernhard Waldenfels che propone un’etica dell’attenzione che è sia un’etica dell’apertura e del riconoscimento dell’altro (...) sia, soprattutto, una risposta e un antidoto alla xenologia e alla xenopolitica. _Parole chiave_: Edmund Husserl; Alfred Schutz; Bernhard Waldenfels; Fenomenologia; Attenzione _Delineating a phenomenology of attention: From Husserl to Waldenfels_ _Abstract_: In this paper we will attempt to outline a phenomenology of attention centered around the concepts of interest and selection. We will start with an analysis of Husserl’s notion of attention, then turn to the reflections of William James, Alfred Schutz and Erving Goffman, all of whom recognized the fundamental role attention plays in the processes by which social actors frame and define reality. Finally, we will consider Bernhard Waldenfels’ ethics of attention. He offers an ethics based on openness to and recognition of the other that, above all, offers both a response and an antidote to xenology and xenopolitics. _Keywords_: Edmund Husserl; Alfred Schutz; Bernhard Waldenfels; Phenomenology; Attention.

Il processo di riconoscimento delle cure palliative quale diritto umano individuale di base ha recentemente riscontrato una proficua quanto attesa accelerazione. Parimenti allo sviluppo tecnico dei nostri giorni non si esauriscono infatti le forme dell’umano sentire e sperare, l’esigenza e l’impeto dell’aver-cura autentico dell’altro, la risposta multidisciplinare, comunitaria e sociale che ne consegue doverosa. È quanto attesta e promuove la recente Dichiarazione di Astana sull’assistenza sanitaria primaria, nel riconoscere le cure palliative tra le forme di cura primarie oggi possibili e (...) dovute ad ogni individuo, espressione di un diritto alla salute non riconducibile a mere forme di assistenzialismo tecnico-burocratico, lontane dall’uomo e dalla vita, ma segno e presenza concreta e tangibile dell’umanità inalienabile da cui esso proviene. Ciò che accomuna in questo percorso di riscoperta e ridestazione è l’essenza della nostra umanità, il desiderio di non cadere intrappolati in una in-umanizzazione collettivizzata, assurda quanto brutale, l’umanità di un diritto alla vita, alla salute e alla sua tutela che nasce rinnovato nel cuore di ogni generazione, la consapevolezza originaria di una determinazione ontologico-esistenziale comune e condivisibile. Il problema della reciprocità del riconoscimento personale fra gli esseri umani nelle pratiche dell’aver-cura e la necessità di un’instancabile promozione di forme di presa in carico realmente globali ed affidabili permea profondamente lo stesso processo di un autentico, efficace e quanto più conforme possibile sviluppo sociale, in una comunità di uomini e di popoli che stenta a riconoscersi come tale e dove occorre innanzitutto curare la speranza affinché ne venga abitata la cura di ogni persona.

We overview the main historical and technological elements characterising the rise, the fall and the recent renaissance of the cognitive approaches to Artificial Intelligence and provide some insights and suggestions about the future directions and challenges that, in our opinion, this discipline needs to face in the next years.

Si tratta di una possibilità, di una disponibilità del pensiero. Dell’orizzonte di comprensione in cui tutti noi ci muoviamo incessantemente, qualunque cosa accada. Di uno spazio interiore ininterrottamente aperto al dialogo con sé stessi, con il mondo, l’esistenza, la vita, con quanto ci accade di positivo o negativo. Il vissuto che si dischiude alla mente, spesso a lungo un cammino nel vuoto e nell’assenza di ogni intuizione, un orizzonte di libertà. Un sistema di scelte e di valori incentrato sui compiti (...) di difesa e tutela della persona umana e della sua vita in ogni sua fase è in sé buono, bello, vero; tuttavia, in particolari situazioni-limite, la scelta di adeguarvisi interiormente non è scontata: essa nasce dal pensiero, nasce dall’istante e dalla riflessione, nasce dalla comprensione e dalla qualità delle relazioni, da una libertà che è personale. Richiedere o rifiutarsi di intraprendere un percorso di cure e di accompagnamento di fine vita, non equivale inoltre a comprenderne sempre o pienamente il senso e talvolta neppure a condividerne integralmente il valore: si tratta di un a-priori del pensiero e allo stesso tempo di un percorso di ricerca individuale sempre aperto, di un compimento di libertà e di relazione, di una scelta da formare e da formarsi. Attraverso l’analisi dei vissuti interiori, delle domande, delle aspettative, delle soluzioni proposte e affrontate durante il percorso di cure palliative emerge con grande forza il ruolo determinante della speranza, la consapevolezza di una responsabilità da dover custodire nonostante la prova, il desiderio di una vita compiuta per sé e per gli altri.

La cura della salute è un fenomeno originario e insieme una necessità fondamentale, dinamica e non trascurabile della vita, dell’esistenza e dell’esperienza personale e comunitaria di ogni essere umano. La primarietà ontologica della cura, evidenziata anche negli studi filosofici più recenti dedicati alle pratiche dell’aver cura, richiama infatti, attraverso la dimensione co-esistentiva dell’essere insieme nel mondo l’uno con l’altro e l’uno per l’altro, alla stessa primarietà etica e al contempo politica della cura nel naturale e positivo sviluppo della struttura relazionale (...) personale e dell’esistenza condivisa. Si tratta di un processo di rilevazione e conseguente impegno nel favorire oggi concretamente percorsi di cura e umanizzazione della pratica medica e sanitaria, sia quotidiana che straordinaria, nonostante molteplici limiti e complessità rintracciabili nelle stesse pratiche contemporanee dell’aver cura, esemplificativamente ricercati e identificati in alcuni recenti lavori internazionali dal carattere necessariamente interdisciplinare. È significativo, infatti, che in alcuni rilevanti documenti circa gli sviluppi di una delle principali frontiere contemporanee dell’aver cura, come quella costituita dal processo di realizzazione, sviluppo, diffusione e promozione locale, nazionale e internazionale delle reti di cure palliative, vengano ad essere centralmente ricercati, identificati e positivamente ri-evidenziati i principali limiti, gli ostacoli e le barriere attualmente riscontrabili nello sviluppo delle reti di cure palliative; oltre alla messa in evidenza di una sempre positiva e necessaria opportunità di gettare lo sguardo verso il futuro e gli orizzonti di sviluppo della presa in carico globale della persona sofferente nelle varie fasi della malattia e in condizioni di estrema vulnerabilità percepita e vissuta.

Come si può essere speranza nel tempo della tecnica? Forse può essere utile interrogare brevemente a tale proposito il pensiero, o meglio approfondire alcune riflessioni presenti nell’elaborazione filosofica di importanti pensatori del Novecento. Attraverso tale procedimento si aprirà forse una prospettiva, un piccolo spiraglio, una via d’uscita tanto per il pensiero, quanto per la comprensione contemporanea della pratica quotidiana dell’aver-cura. Non deve stupire se si rimanda a classici del pensiero filosofico, ciò che muove ogni azione, soprattutto in ambito clinico e (...) sanitario, non è forse una sempre personale visione del mondo, che ha scelto deliberatamente di aver-cura dell’altro opponendosi, per quanto possibile con tutti i mezzi della conoscenza e del cuore, ad un altrettanto diffusa visione dell’uomo che lo vede invece preda degli eventi e della caducità, al di là di ogni possibile e autentico intervento e soccorso dell’altro? Partendo dalle riflessioni circa le nozioni di “situazione-limite” e “aver-cura”, proposte rispettivamente da autori come Karl Jaspers e Martin Heidegger, è infatti possibile indicare una prospettiva teorico-pratica contemporanea circa il discorso sulla pratica di cura nel tempo della tecnica. Vedremo che i classici del pensiero del Novecento hanno ancora qualcosa da dirci, che una qualche comunicazione fra discipline differenti è ancora possibile; almeno ogni volta in cui, come nel caso della dimensione e rete di cure palliative e della presa in carico globale della persona sofferente, si avvicini l’uomo aperti alla sua realtà omnicomprensiva, soprattutto quando si parla di dolore e sofferenza, elementi comuni ad ogni uomo e ogni tempo.

We define and study monadic MV-algebras as pairs of MV-algebras one of which is a special case of relatively complete subalgebra named m-relatively complete. An m-relatively complete subalgebra determines a unique monadic operator. A necessary and sufficient condition is given for a subalgebra to be m-relatively complete. A description of the free cyclic monadic MV-algebra is also given.

This essay analyzes the reflection of Alfred Schütz on music. The first part will focus on the analysis of those that for Schütz are the constitutive elements of the phenomenology of music. The second part will focus on the idea of music as a social interaction and relationship of mutual harmony. The aim of the work is to demonstrate that Schütz’s reflection on music does not constitute an isolated element within his thought process, but rather it constitutes a fundamental element (...) of his reflection because music represents in an exemplary way the structure of the social relationship. Therefore, it will be demonstrated that music is for Schütz a relationship based on the sharing of space and time, or an intersubjective sharing of reality that allows simultaneous sharing in the experiences of one’s interlocutor.

In this paper we prove that the category of abelianl-groups is equivalent to the category of perfect MV-algebras. Furthermore, we give a finite equational axiomatization of the variety generated by perfect MV-algebras.

Controversies around large-scale development projects offer many cases and insights which may be analyzed through the lenses of corporate social (_ir_)responsibility (CS_I_R) and business ethics studies. In this paper, we confront the CSR narratives and strategies of _WeBuild_ (formerly known as _Salini Impregilo_), an Italian transnational construction company. Starting from the Global Atlas of Environmental Justice (EJAtlas), we collect evidence from NGOs, environmental justice organizations, journalists, scholars, and community leaders on socio-environmental injustices and controversies surrounding 38 large hydropower schemes built (...) by the corporation throughout the last century. As a counter-reporting exercise, we code (un)sustainability discourses from a plurality of sources, looking at their discrepancy under the critical lenses of post-normal science and political ecology, with environmental justice as a normative framework. Our results show how the mismatch of narratives can be interpreted by considering the voluntary, self-reporting, non-binding nature of CSR accounting performed by a corporation wishing to grow in a global competitive market. Contributing to critical perspectives on political CS(I)R, we question the reliability of current CSR mechanisms and instruments, calling for the inclusion of complexity dimensions in and a re-politicization of CS(I)R accounting and ethics. We argue that the fields of post-normal science and political ecology can contribute to these goals. (shrink)

The MV-algebra S m w is obtained from the (m+1)-valued ukasiewicz chain by adding infinitesimals, in the same way as Chang's algebra is obtained from the two-valued chain. These algebras were introduced by Komori in his study of varieties of MV-algebras. In this paper we describe the finitely generated totally ordered algebras in the variety MV m w generated by S m w . This yields an easy description of the free MV m w -algebras over one generator. We characterize (...) the automorphism groups of the free MV-algebras over finitely many generators. (shrink)

We present a stronger variation of state MV-algebras, recently presented by T. Flaminio and F. Montagna, which we call state-morphism MV-algebras. Such structures are MV-algebras with an internal notion, a state-morphism operator. We describe the categorical equivalences of such state MV-algebras with the category of unital Abelian ℓ-groups with a fixed state operator and present their basic properties. In addition, in contrast to state MV-algebras, we are able to describe all subdirectly irreducible state-morphism MV-algebras.

It is currently assumed that exposure to an artificial blue-enriched light enhances human alertness and task performance, but recent research has suggested that behavioural effects are influenced by the basal state of arousal. Here we tested whether the effect of blue-enriched lighting on vigilance performance depends on participants’ arousal level. Twenty-four participants completed four sessions (blue-enriched vs. dim light x low vs. high arousal) at 10 pm on four consecutive days, following a repeated-measures design. Participants’ arousal was manipulated parametrically through (...) the execution of a cycling task at two intensities (low vs. moderate), and was checked by monitoring their heart rate. On each session, distal and proximal skin temperatures were recorded as a neuroergonomic index of vigilance, while participants performed a 20-min psychomotor vigilance task (PVT) under either blue-enriched light or dim light conditions. The Positive and Negative Affect Schedule (PANAS), Karolinska Sleepiness Scale (KSS) and Borg Rating of Perceived Exertion Scale (RPE) were used to measure subjective psychological state. The results showed that the exercise-induced manipulation of arousal produced robust alerting effects in most measures, while the lighting manipulation only attenuated subjective sleepiness and enhanced positive affect, but it did not influence behaviour or physiology. Acute exposure to a blue-enriched light was practically ineffective when the arousal level was over baseline. The present research favoured the use of acute physical exercise over acute exposure to blue-enriched lighting in order to boost humans’ alertness when necessary, as in work settings where maintaining optimal levels of attention is difficult (shift work, night-work, vigilance tasks) and necessary to prevent human error and accidents.

Recent investigations have explored how large-scale systems in the brain operate in the processes of retrieving knowledge for words and concepts. Much of the crucial evidence derives from lesion studies, because word retrieval and concept retrieval can be clearly dissociated in brain-damaged individuals. We discuss these findings from the perspective of our neurobiological framework, which is cited in Pulvermüller's target article.
