§ 74. Giulio Bertoni and linguistics. In view of the attitudes expressed in his latest writing, a critique easily could be written that cuts the legs out from under Bertoni's linguistics. It could be easily demonstrated that Bertoni has succeeded neither in providing a general reformulation of Bartoli's innovations in linguistics, nor has he understood these innovations along with their practical and theoretical import. In an article published some years age dealing with linguistic studies in Italy, Bertoni completely fails to (...) distinguish Bartoli from the run of the mill linguists. Instead, by subde ambiguities, he relegates him to a secondary position, unlike Casella who emphasizes Bartoli originality. (shrink)

Columbia University Press's multivolume _Prison Notebooks_ is the only complete critical edition of Antonio Gramsci's seminal writings in English. Based on the authoritative Italian edition of Gramsci's work, _Quaderni del Carcere_, this comprehensive translation presents the intellectual as he ought to be read and understood, with critical notes that clarify Gramsci's history, culture, and sources; an index of names; and a contextualization of the thinker's ideas against his earlier writings and letters. This set includes notebooks 1 through 8 with (...) all attendant notes and materials and is an indispensible resource for scholars in the humanities and social sciences. (shrink)

We propose a nonmonotonic Description Logic of typicality able to account for the phenomenon of combining prototypical concepts, an open problem in the fields of AI and cognitive modelling. Our logic extends the logic of typicality ALC + TR, based on the notion of rational closure, by inclusions p :: T(C) v D (“we have probability p that typical Cs are Ds”), coming from the distributed semantics of probabilistic Description Logics. Additionally, it embeds a set of cognitive heuristics for concept (...) combination. We show that the complexity of reasoning in our logic is EXPTIME-complete as in ALC. (shrink)

The presence of a theory of the transmigration of the soul or, according to Empedocles’ words, of the δαίμων is a controversial issue among scholars. A major difficulty arises when one tries to read the fragments of the Purifications – where this theme is particularly recurrent – in conjunction with those usually attributed to the poem On nature. The aim of this paper is to suggest a ‘method’ to analyse the extant fragments, and to offer a possible interpretation of the (...) nature of the so–called cycle of the δαίμων. On the one hand, I shall try to show that the two poems, if read together, can provide a ‘salvific’ message. As a matter of fact, the description of the cosmic order that emerges from the poem On nature might convey the same prescription as stated in the Purifications for following the universal laws, which would ultimately allow human beings to be happy even in an age of universal evil. On the other hand, I shall propose to identify the δαίμων with the roots, which can escape from the cycle – i.e. become happy – when they are shaped as human minds, thanks to the way in which the processes of knowledge work.

Food pantries play a growing role in supporting households facing or at risk of food insecurity in the United States. They also support emergency response and recovery following disasters and extreme weather events. Although food pantries are often placed in close proximity to communities with the highest rates of poverty and risk of food insecurity, access to these facilities can be disrupted during and after extreme events. Decreased access to food pantries following disasters can be particularly problematic as the need (...) for these services is also likely to grow after such events. Despite the vast body of research on food retail access and food environments, relatively little research has utilized spatial analysis to understand food pantry access, particularly after extreme events. Using Geographic Information Systems (GIS), we characterize changes in access to food pantries following flooding events in Harris County, Texas—a highly populated and flood prone region with high levels of food insecurity and poverty. Specifically, our study models disruptions in road networks due to flooding and assesses the impacts of these disruptions on proximity to food pantries. The results reveal that much of Harris County sees only small increases in travel distance to food pantries due to extreme flooding, but some areas may be unable to access food pantries at all. This research highlights the potential and some of the limits of private food assistance networks to support emergency response efforts. (shrink)

. The aim of this paper is to analyse the ways in which the nature of true philosophers is described in Plato’s Timaeus. By examining the distinction between two kinds of opinion – one absolutely false, the other reliably true – I will try to show that Plato coined a new term to denote both true philosophers and the characteristics of their knowledge. From being a ‘love of wisdom’, true philosophy came to be defined as a ‘passion for science’. Finally, (...) I will try to illustrate the protreptic intent underlying this choice of words and how it concerns the main critical target of the Timaeus, the so-called Presocratics. (shrink)

The paper introduces an extension of the proposal according to which conceptual representations in cognitive agents should be intended as heterogeneous proxytypes. The main contribution of this paper is in that it details how to reconcile, under a heterogeneous representational perspective, different theories of typicality about conceptual representation and reasoning. In particular, it provides a novel theoretical hypothesis - as well as a novel categorization algorithm called DELTA - showing how to integrate the representational and reasoning assumptions of the theory-theory (...) of concepts with the those ascribed to the prototype and exemplars-based theories.

The aim of the paper is to investigate the role played by causality, and more specifically the no-signaling condition, in the assessment of the quantum theory. To this end, we discuss why it is important that even a non-relativistic theory such as Quantum Mechanics doesn’t imply a violation of this condition. Then, we use this argument to prove an original result stating that the destructive behaviour of the measurement process on the entanglement properties of quantum systems is a necessary and (...) unavoidable feature of the quantum theory. Finally, we critically review the no-cloning theorem. The original formulation of the theorem states that a linear quantum cloning machine, designed in order to successfully clone states that coincide with appropriate basis vectors, fails to copy states that are a non-trivial superposition of those basis vectors; we will furthermore prove that such a linear cloning device, even with the hypothesis that it can only clone basis vectors successfully, may provide a violation of the no-signaling condition and therefore cannot exist.

Lo scopo del presente lavoro è indagare la peculiare legittimazione dell’impegno politico per i filosofi proposta da Platone e accolta dai suoi immediati discepoli nella cosiddetta Prima Accademia: particolare attenzione sarà rivolta, soprattutto, alla «terza ondata» della _Repubblica_. Attraverso opportuni riferimenti alla _Lettera VII_, si mostrerà come la terza ondata costituisca il cuore del progetto di riforma politica e sociale di Platone, il quale invita l’intellettuale a concepire la propria missione politica o come istituzione di un regno filosofico o come (...) consiglio e aiuto da prestare a un re o a un signore: in entrambi i casi, l’immagine del governo di un solo uomo serve a connotare lo scenario preferibile per garantire l’istituzionalizzazione politica della filosofia. È così che, allora, i discepoli di Platone tentarono di stabilire contatti con realtà monarchiche o tiranniche accettando di farsi legislatori o consiglieri di un singolo individuo al comando, il quale veniva concepito come il perfetto connubio tra sapere e potere nel solco delle teorie del maestro.

Riassunto Il lavoro si incentra sulla figura di Galeria Valeria, figlia di Diocleziano e moglie di Galerio. Un’attenzione particolare è stata riservata a Galeria come moglie e madre: l’analisi si sofferma sulla notizia del retore Lattanzio inerente alla sterilità di Galeria Valeria e alla conseguente adozione di un figlio, Candidiano, che Galerio avrebbe avuto dall’unione con una concubina, aprendo un ampio excursus su problematiche di carattere giuridico quali l’adoptio/adrogatio, la legittimazione, il iustum matrimonium e il concubinato. Si cerca poi di (...) affrontare la complessa questione riguardante l’adesione o meno da parte della donna al cristianesimo, anche mediante l’analisi comparativa del testo lattanziano con un passo rabbinico. Al fine di far luce sull’individualità e sulla regalità della donna si è poi proceduto all’analisi delle iconografie presenti sul recto delle monete con effigiato il ritratto dell’Augusta. Lo studio di una serie di epigrafi, selezionate in quanto attestanti il titolo di mater castrorum, ha consentito di rinvenire le nobili virtù dell’Augusta connotata come sacratissima / θιοτάτη, piissima / σεβαστή / εὐσεβεστάτη. L’ultima parte del lavoro è dedicata alla sorte di Galeria vedova esule senza fissa dimora prima, e poi destinata ad una fine atroce, per lasciare quindi spazio a riflessioni nuovamente sul rapporto Galeria Valeria – Candidiano, e concludere con la ‘Valeria’, quella provincia della Pannonia Inferiore così denominata da Galerio in onore della moglie.

__. L’articolo analizza la descrizione della natura delle piante e la tacita giustificazione del vegetarianismo fornite da Platone nel _Timeo_. Tale pratica alimentare sembra assumere un’utilità esclusivamente fisiologica: potrebbe darsi che Platone si fosse opposto a quanti professavano il vegetarianismo in qualità di mezzo necessario per purificare l’anima e per raggiungere la felicità, come gli orfici, i pitagorici, Empedocle ma anche il suo discepolo Senocrate. Attraverso il particolare valore attribuito a una dieta vegetariana, Platone priva di validità la pretesa degli (...) altri filosofi: solo lo studio delle idee permette di ottenere la felicità. _Abstract_. The aim of this paper is to analyse Plato’s description of plants and his tacit justification of vegetarianism in the _Timaeus_. This practice seems to possess exclusively a physiological relevance: I argue that Plato is opposing the idea of vegetarianism as a superior way to purify one’s soul and achieve happiness, how it was being professed by the Orphics, the Pythagoreans, Empedocles, and even by his disciple Xenocrates. In the _Timaeus_, with the justification of vegetarianism only for physiological purposes, Plato is discrediting other philosophers’ conception of vegetarianism and perfect life: only the study of the noetic world grants ultimate happiness.

The publication of this book is an event in the making. All over the world scientists, psychologists, and philosophers are waiting to read Antonio Damasio's new theory of the nature of consciousness and the construction of the self. A renowned and revered scientist and clinician, Damasio has spent decades following amnesiacs down hospital corridors, waiting for comatose patients to awaken, and devising ingenious research using PET scans to piece together the great puzzle of consciousness. In his bestselling Descartes' Error, (...) Damasio revealed the critical importance of emotion in the making of reason. Building on this foundation, he now shows how consciousness is created. Consciousness is the feeling of what happens-our mind noticing the body's reaction to the world and responding to that experience. Without our bodies there can be no consciousness, which is at heart a mechanism for survival that engages body, emotion, and mind in the glorious spiral of human life. A hymn to the possibilities of human existence, a magnificent work of ingenious science, a gorgeously written book, The Feeling of What Happens is already being hailed as a classic. (shrink)

This article addresses an open problem in the area of cognitive systems and architectures: namely the problem of handling (in terms of processing and reasoning capabilities) complex knowledge structures that can be at least plausibly comparable, both in terms of size and of typology of the encoded information, to the knowledge that humans process daily for executing everyday activities. Handling a huge amount of knowledge, and selectively retrieve it according to the needs emerging in different situational scenarios, is an important (...) aspect of human intelligence. For this task, in fact, humans adopt a wide range of heuristics (Gigerenzer & Todd) due to their “bounded rationality” (Simon, 1957). In this perspective, one of the requirements that should be considered for the design, the realization and the evaluation of intelligent cognitively-inspired systems should be rep- resented by their ability of heuristically identify and retrieve, from the general knowledge stored in their artificial Long Term Memory (LTM), that one which is synthetically and contextually relevant. This requirement, however, is often neglected. Currently, artificial cognitive systems and architectures are not able, de facto, to deal with complex knowledge structures that can be even slightly comparable to the knowledge heuris- tically managed by humans. In this paper I will argue that this is not only a technological problem but also an epistemological one and I will briefly sketch a proposal for a possible solution. (shrink)

Antonio Negri, one of the world's leading scholars on Baruch Spinoza (1632-1677) and his contemporary legacy, offers a straightforward explanation of the philosopher's elaborate arguments and a persuasive case for his ongoing relevance. Responding to a resurgent interest in Spinoza's thought and its potential application to contemporary global issues, Negri demonstrates the thinker's special value to politics, philosophy, and related disciplines. Negri's work is both a return to and an advancement of his initial affirmation of Spinozian thought in _The (...) Savage Anomaly_. He further defends his understanding of the philosopher as a proto-postmodernist, or a thinker who is just now, with the advent of the postmodern, becoming contemporary. Negri also connects Spinoza's theories to recent trends in political philosophy, particularly the reengagement with Carl Schmitt's "political theology," and the history of philosophy, including the argument that Spinoza belongs to a "radical enlightenment." By positioning Spinoza as a contemporary revolutionary intellectual, Negri addresses and effectively defeats twentieth-century critiques of the thinker waged by Jacques Derrida, Alain Badiou, and Giorgio Agamben.

Endowing artificial systems with explanatory capacities about the reasons guiding their decisions, represents a crucial challenge and research objective in the current fields of Artificial Intelligence (AI) and Computational Cognitive Science [Langley et al., 2017]. Current mainstream AI systems, in fact, despite the enormous progresses reached in specific tasks, mostly fail to provide a transparent account of the reasons determining their behavior (both in cases of a successful or unsuccessful output). This is due to the fact that the classical problem (...) of opacity in artificial neural networks (ANNs) explodes with the adoption of current Deep Learning techniques [LeCun, Bengio, Hinton, 2015]. In this paper we argue that the explanatory deficit of such techniques represents an important problem, that limits their adoption in the cognitive modelling and computational cognitive science arena. In particular we will show how the current attempts of providing explanations of the deep nets behaviour (see e.g. [Ritter et al. 2017] are not satisfactory. As a possibile way out to this problem, we present two different research strategies. The first strategy aims at dealing with the opacity problem by providing a more abstract interpretation of neural mechanisms and representations. This approach is adopted, for example, by the biologically inspired SPAUN architecture [Eliasmith et al., 2012] and by other proposals suggesting, for example, the interpretation of neural networks in terms of the Conceptual Spaces framework [Gärdenfors 2000, Lieto, Chella and Frixione, 2017]. All such proposals presuppose that the neural level of representation can be considered somehow irrelevant for attacking the problem of explanation [Lieto, Lebiere and Oltramari, 2017]. In our opinion, pursuing this research direction can still preserve the use of deep learning techniques in artificial cognitive models provided that novel and additional results in terms of “transparency” are obtained. The second strategy is somehow at odds with respect to the previous one and tries to address the explanatory issue by avoiding to directly solve the “opacity” problem. In this case, the idea is that one of resorting to pre-compiled plausible explanatory models of the word used in combination with deep-nets (see e.g. [Augello et al. 2017]). We argue that this research agenda, even if does not directly fits the explanatory needs of Computational Cognitive Science, can still be useful to provide results in the area of applied AI aiming at shedding light on the models of interaction between low level and high level tasks (e.g. between perceptual categorization and explanantion) in artificial systems.

Combining typical knowledge to generate novel concepts is an important creative trait of human cognition. Dealing with such ability requires, from an AI perspective, the harmonization of two conflicting requirements that are hardly accommodated in symbolic systems: the need of a syntactic compositionality (typical of logical systems) and that one concerning the exhibition of typicality effects (see Frixione and Lieto, 2012). In this work we provide a logical framework able to account for this type of human-like concept combination. We propose (...) a nonmonotonic Description Logic of typicality called TCL (Typicality-based Compositional Logic). (shrink)

Persuasive technologies can adopt several strategies to change the attitudes and behaviors of their users. In this work I synthesize the lessons learned from three empirical case studies on automated persuasion that have been carried out in the last decade in the contexts of: persuasive news recommendations, social robotics, and e-commerce, respectively. In particular, such studies have assessed, in the technological domain, the effects of nudging techniques relying on well known persuasive argumentation schemas and on framing strategies. In discussing the (...) main findings, I will argue that the obtained persuasive effects are due to the fact that such techniques leverage on cognitive mechanisms that refer to the “system 1” types of automatic processes hypothesized in the context of the dual process theory of reasoning. As a consequence of this state of affairs, any automated persuasive systems (used for ethical purposes: e.g. suggesting good health habits) should be able to re-use these types of system 1 strategies in order to gradually take the users in an argumentation territory where system 2 processes can take place. -/- .
