Dalle decisioni algoritmiche alle raccomandazioni sugli acquisti, dai sex robot alla sorveglianza sociale, dalla cybersicurezza all’autonomia operativa dei veicoli e delle armi, l’impatto dell’intelligenza artificiale e della robotica sulla vita delle persone è sempre più ramificato e pervasivo. Il volume offre un quadro d’insieme delle questioni etiche sollevate dall’incontro tra automi e individui nella società contemporanea: la protezione dell’autonomia a fronte della raccolta minuziosa di dati personali, le forme di benessere collettivo da promuovere attraverso l’automazione, la trasparenza e l’equità delle (...) decisioni prese con il supporto di un algoritmo, il ruolo dei sistemi intelligenti nella crisi ambientale. L’automazione non è segno incontrovertibile di sventura, ma nemmeno indizio sicuro di progresso. Cosa sarà delle persone, delle società e della vita sul nostro pianeta dipende in modo cruciale da come sapremo affrontare le sfide etiche dell’età degli automi. (shrink)

Both physiological and evolutionary criteria of biological individuality are underpinned by the idea that an individual is a functionally integrated whole. However, a precise account of functional integration has not been provided so far, and current notions are not developed in the details, especially in the case of composite systems. To address this issue, this paper focuses on the organisational dimension of two representative associations of prokaryotes: biofilms and the endosymbiosis between prokaryotes. Some critical voices have been raised against the (...) thesis that biofilms are biological individuals. Nevertheless, it has not been investigated which structural and functional obstacles may prevent them from being fully integrated physiological or evolutionary units. By contrast, the endosymbiotic association of different species of prokaryotes has the potential for achieving a different type of physiological integration based on a common boundary and interlocked functions. This type of association had made it possible, under specific conditions, to evolve endosymbionts into fully integrated organelles. This paper therefore has three aims: first, to analyse the organisational conditions and the physiological mechanisms that enable integration in prokaryotic associations; second, to discuss the organisational differences between biofilms and prokaryotic endosymbiosis and the types of integration they achieve; finally, to provide a more precise account of functional integration based on these case studies.

Much of the current research in regenerative medicine concentrates on stem-cell therapy that exploits the regenerative capacities of stem cells when injected into different types of human tissues. Although new therapeutic paths have been opened up by induced pluripotent cells and human mesenchymal cells, the rate of success is still low and mainly due to the difficulties of managing cell proliferation and differentiation, giving rise to non-controlled stem cell differentiation that ultimately leads to cancer. Despite being still far from becoming (...) a reality, these studies highlight the role of physical and biological constraints (e.g., cues and morphogenetic fields) placed by tissue microenvironment on stem cell fate. This asks for a clarification of the coupling of stem cells and microenvironmental factors in regenerative medicine. We argue that extracellular matrix and stem cells have a causal reciprocal and asymmetric relationship in that the 3D organization and composition of the extracellular matrix establish a spatial, temporal, and mechanical control over the fate of stem cells, which enable them to interact and control (as well as be controlled by) the cellular components and soluble factors of microenvironment. Such an account clarifies the notions of stemness and stem cell regeneration consistently with that of microenvironment. (shrink)

In this paper, we report on an experiment with The Walking Dead (TWD), which is a narrative-driven adventure game with morally charged decisions set in a post-apocalyptic world filled with zombies. This study aimed to identify physiological markers of moral decisions and non-moral decisions using infrared thermal imaging (ITI). ITI is a non-invasive tool used to capture thermal variations due to blood flow in specific body regions that might be caused by sympathetic activity. Results show that moral decisions seem to (...) elicit a significant decrease in temperature in the chin region 20 seconds after participants are presented with a moral decision. However, given the small sample involved, and the lack of significance in other regions, future studies might be needed to confirm the results obtained in this work. (shrink)

This study aimed to evaluate if eye blinks can be used to discriminate players with different performance in a session of Nintendo Entertainment System (NES) Tetris. To that end, we developed a state-of-the-art method for blink extraction from EAR measures, which is robust enough to be used with data collected by a low-grade webcam such as the ones widely available on laptop computers. Our results show a significant decrease in blink rate per minute (blinks/m) during the first minute of playing (...) Tetris. After having defined 3 groups of proficiency based on in-game performance (Novices, Intermediates, and Experts) we found out that expert players display a significantly lower decrease in blinks/m compared to novices during the first minute of gameplay, which shows that Tetris players' proficiency can be detected by looking at eye blinks/m variations during the early phase of a game session. This difference in blinks/m is observed throughout the entire game session, which supports the general conclusion that proficient Tetris players have a lower decrease in blinks/m, even when playing more difficult levels. Finally, we offer some interpretations of this effect and the relationship that our results may have with the visual cognitive workload experienced during the gameplay. (shrink)

In this study, we predict the different levels of performance in a Nintendo Entertainment System (NES) Tetris session based on the score and the number of matches played by the players. Using the first 45 seconds of gameplay, a Random Forest Classifier was trained on the five keys used in the game obtaining a ROC_AUC score of 0.80. Further analysis revealed that the number of down keys (forced drop) and the number of left keys (left translation) are the most relevant (...) keys in this task, showing that by merely including the data from these two keys our Random Forest Classifier reached a ROC_AUC score of 0.83.We conclude that the keylogger data during the early phases of a game session can be successfully used to predict performance in longer sessions of Tetris.

In this study, we extracted facial action units (AUs) data during a Hearthstone tournament to investigate behavioural differences between expert, intermediate, and novice players. Our aim was to obtain insights into the nature of expertise and how it may be tracked using non-invasive methods such as AUs. These insights may shed light on the endogenous responses in the player and at the same time may provide information to the opponents during a competition. Our results show that player expertise may be (...) characterised by specific patterns in facial expressions. More specifically, AU17 (chin raiser), AU25 (lips apart), and AU26 (jaws drop) intensity responses during gameplay may vary according to players' expertise. Such results were obtained by training a random forest classifier to test whether we can use these three AUs alone to accurately detect players' expertise. The classifier reached 0.75 accuracy on 5-fold cross-validation, after balancing the class weights, and 0.85 after having applied the Synthetic Minority Over-sampling Technique (SMOTE) function. These results suggest that AUs can be effectively used to discriminate different levels of expertise in competitive video game players. (shrink)

In this study, we analyzed the blinking behavior of players in a video game tournament. Our aim was to test whether spontaneous blink patterns differ across levels of expertise. We used blink rate, blink duration, blink frequency, and eyelid movements represented by the Eye Aspect Ratio (EAR) to train a machine learning classifier to discriminate between different levels of expertise. Classifier performance was highly influenced by features such as the mean, standard deviation and median EAR. Moreover, further analysis suggests that (...) blinking rate and blink duration are likely to increase along with the level of expertise. We speculate this may be indicative of a reduction in cognitive load and lowered stress of expert players. In general, our results suggest that EAR and blink patterns can be used to identify different levels of expertise of video game players. (shrink)

The aim of this paper is to address the question why the old Marx was interested in mathematics. While most interpreters argue that his interest was philosophical, it is maintained here that Marx tried to understand the developments of Economics and, particularly, of marginalism and that, in order to fully understand the new theoretical paradigma, he needed to study a particular branch of Mathematics, namely the derivatives.

The article presents another of those ingenious mind, rebels to the yoke of religion, typical of the Italian Renaissance. Converted to Calvinism and therefore condemned to death by the Inquisition, Guglielmo Grataroli (1516-1568) became a defender of heterodox doctrine. His translation of a report of the Waldensian massacre in Calabria became part of the history of Protestant martyrs. He was the author of numerous treatises on various subjects, for which he widely used the works of Giovanni Michele Alberto da (...) Carrara, Antoine Mizauld and Gerolamo Cardano. The perfect correspondence of the topics discussed makes it probable that Giordano Bruno knew his writings. In particular, the De mutatione temporum, eiusque signis perpetuis may have inspired the De’ segni de’ tempi, a Bruno’s lost opera. This allows us to conjecture the content of the work with greater reliability. (shrink)

Truth is a key notion in Ockham’s philosophical reductionist program, a notion that has been the object of contrasting interpretations in scholarship. My interpretation is that, for Ockham, ‘being true’ expresses an epistemological relation, namely the one through which our mind reflects on a proposition of language, compares it with an extra-mental state of affairs, and thus ascertains their correspondence. Placing truth at a point of intersection of language with mind and reality, Ockham’s interpretation of Aristotle’s characterization of philosophy as (...) the science of truth comes to be innovative. For Ockham, philosophy is a meticulous training of interpretation of language in order to account correctly for the truth-value of propositions. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it is contradictory for (...) God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

Il Tractatus de praedestinatione et de praescientia Dei respectu futurorum contingentium, composto da Guglielmo di Ockham tra il 1321 e il 1324, costituisce uno snodo cruciale nelle discussioni medievali sul tema del fatalismo teologico e sulle questioni che vi sono implicate, come la conoscenza dei futuri contingenti e il compatibilismo tra prescienza divina e libero arbitrio. Raccogliendo e ripensando fonti di diversa provenienza, Roberto Grossatesta e Pietro Lombardo in primis, il Venerabilis inceptor sposta il problema sul piano epistemologico e (...) linguistico, affrontandolo dal punto di vista di un’analisi proposizionale degli enunciati che parlano dei contingenti futuri. In questo modo egli affida agli strumenti dell’argomentazione logica e dell’indagine semantica il compito di sciogliere le implicazioni teologiche della questione, in una teoria che garantisca al contempo la prescienza di Dio e la libera volontà umana. Il principio della soluzione ockhamiana, che costituirà un punto di riferimento – pro o contro – nei dibattiti teologici del XIV secolo, consiste nell’intreccio tra analisi proposizionale e logica fidei, in nome di una soluzione pragmatica del dilemma compatibilista: come mostra il caso esemplare della profezia, gli enunciati della scienza divina costituiscono i postulati di una logica della credenza che poi procede da quelle premesse, attraverso una catena argomentativa, a formulare i precetti che guideranno i passi del cristiano nel mondo. Il volume rende disponibile per la prima volta al lettore non soltanto la prima traduzione in italiano del Tractatus, ma anche un ricco apparato di testi (le distinctiones 38, 39 e 40 dell’Ordinatio, i capitoli 7 e 27 della Summa Logicae, la quaestio IV.4 dei Quodlibeta, le Quaestiones in Libros Physicorum 41 e 44, il prologo della Expositio in libros Physicorum e un estratto dalla Expositio in Librum Perihermeneias Aristotelis) che consente di ricostruire in modo coerente una teoria ockhamiana della contingenza e di gettare luce su una nuova interpretazione del pensiero del teologo e filosofo inglese.

This article presents a few research findings related to the Geomantia attributed to William of Moerbeke. It consists of three sections: The first provides evidence for the classification of the Geomantia within the genre of the medieval compilations. The second includes a comparison of the Geomantia with the Ars geomantie nova of Batholomew of Parma and a few considerations on the datation of the treatise attributed to Moerbeke, based on this assessment. The third brings to the attention of scholars an (...) unpublished marginal note concerning the date of composition of the Geomantia. (shrink)

Several years ago Guglielmo Carchedi (2008; 2012) published in S&S two interesting pieces on Marx’s dialectics and mathematics. His basic aim was to discover whether Marx’s Mathematical Manuscripts provide a new insight into Marx’s dialectics. The reading he suggested was addressed to Marx alone, i.e., without Hegel and Engels. This, he argued, is the only way to grasp Marx’s dialectics if one wants to understand Marx in his own terms. Since Marx never explicated his notion of dialectics, we ought (...) to derive it from Marx’s own work. To this end, Carchedi first defined “dialectics as a method of social research” (Carchedi, 2008, 416), and then listed three principles of dialectics: 1) “all phenomena are always both realized and potential”; 2) “they are always both determinant and determined”; 3) they are “always subject to movement and change” (ibid.). Later he added a fourth principle: 4) “social phenomena’s movement (change) is tendential” (Carchedi, 2012, 547). He emphasized that these principles are limited to society and not to be confused with nature, because society, unlike nature, necessarily involves “human volition and consciousness” (ibid.). For this reason, “Engels’ dialectics of nature cannot be applied to society” (ibid.), a claim he also asserted in his book Behind the Crisis (2011, 37–8). (shrink)

Nell'alto medioevo vi erano tre possibilità per il filosofo che volesse difendere l'esistenza degli universali: in primo luogo ante rem, seguendo la linea platonico-agostiniana degli universali trascendenti e questa è la via teologica; in secondo luogo la via post rem, cioè la via del concettualismo, conosciuta oggi come astrattismo, per cui gli universali sono il prodotto dell'astrazione della mente e questa è una via logica; la terza via è quella in re e difende gli universali immanenti che esistono negli universali (...) ed è una risposta ontologica. La seconda via fu difesa da Boezio nel secondo commento a Porfirio. La prima teoria è stata generalmente accettata da tutti i filosofi dell'alto medioevo eccetto Abelardo, mentre la terza via, quella degli universali immanenti, che ha come fonti antiche l'Isagoge di Porfirio e le Categoriae di Aristotele, fu difesa principalmente da quattro autori: Giovanni Scoto Eriugena, Anselmo d'Aosta, Odone di Cambrai e Guglielmo di Champeaux. L'A. prende in esame e confronta le soluzioni di Anselmo di Canterbury e Odone di Cambrai. (shrink)
