In this paper, inspired by methods of Bigard, Keimel, and Wolfenstein , we develop an approach to sheaf representations of MV-algebras which combines two techniques for the representation of MV-algebras devised by Filipoiu and Georgescu and by Dubuc and Poveda . Following Davey approach , we use a subdirect representation of MV-algebras that is based on local MV-algebras. This allowed us to obtain: a representation of any MV-algebras as MV-algebra of all global sections of a sheaf of local MV-algebras on (...) the spectruum of its prime ideals; a representation of MV-algebras, having the space of minimal prime ideals compact, as MV-algebra of all global sections of a Hausdorff sheaf of MV-chains on the space of minimal prime ideals, which is a Stone space; an adjunction between the category of all MV-algebras and the category of MV-algebraic spaces, where an MV-algebraic space is a pair , where X is a compact topological space and F is a sheaf of MV-algebras with stalks that are local.

In this paper, we discuss the importance of measurement in quantum mechanics and the so-called measurement problem. Any quantum system can be described as a linear combination of eigenstates of an operator representing a physical quantity; this means that the system can be in a superposition of states that corresponds to different eigenvalues, i.e., different physical outcomes, each one incompatible with the others. The measurement process converts a state of superposition in a well-defined state. We show that, if we describe (...) the measurement by the standard laws of quantum mechanics, the system would preserve its state of superposition even on a macroscopic scale. Since this is not the case, we assume that a measurement does not obey to standard quantum mechanics, but to a new set of laws that form a “quantum measurement theory”. (shrink)

In this paper we first provide a new axiomatization of algebraically closed MV-algebras based on McNaughtonʼs Theorem. Then we turn to sheaves, and we represent algebraically closed MV-algebras as algebras of global sections of sheaves, where the stalks are divisible MV-chains and the base space is Stonean.

Reconfigures classic aesthetic concepts in relation to the novelty introduced by virtual bodies.

The problem of aesthetic experience in a virtual environment could be reformulated as: what can we learn about aesthetics from the perspective of ‘aesthetic experience in virtual environments’, given the specific nature of such an environment? The discourse goes in circles, because it is always from theories elaborated in the field of the so-called ‘real’ that we develop the difference, but it is a process typically philosophical, that, on the other hand, can make sense only if it can be shown (...) that the virtual is an existent being that has an ontological structure of its own. The ontology of this strange object–event, and of its relationship to space–time, must therefore be addressed: what are the conditions of identity for a virtual body? What are its limits? In what sense does it have borders? Also, its specific temporality and its connection to human and computer memories are arguable dimensions that deserve analysis, as they directly affect an ontology of the virtual body, the difference between the virtual and the possible, and the relationship between the human body and the virtual body. However, the specific character of the virtual is to be an intermediate entity between object and event, between thing and image, so that virtual bodies represent a hybrid, interactive world which can be visualized as synthetic image, an immersive hybrid engaging the corporeality of the user and merging with the virtual body’s image; this hybridization, between the body of the spectator–actor and the virtual space in which it is immersed, is difficult to define with singularity.

The essay concerns the relationship between the notion of aura and the notion of digital image. The digital image is not simply image-of, not only mimesis of an, identifiable or not, thing or image, and so it does not have a simulacral essence. On the other hand, it is not even an icon or an original image; it is rather a genetic relational form belonging to a multiple rendering system. The digital image is not exactly “image”, but rather body-image, because (...) it is made up of ordered sequences of binary units, or otherwise character strings developing on different levels of a syntax which builds the coincidence of these strings and the sensible appearances, at present mainly sound or visual, but generally perceptible.

This book investigates the ontological state of relations in a unique way. Starting with the notion of system, it shows that the system can be understood as a relational structure, and that relations can be assessed within themselves, with no need to transform relations in elements. “Relations” are understood in contrast to “relational property”: without a relation there is no identity, therefore no existence. What allows us to do that without hypostatizing the relation, and without immediately taking it simply as (...) a causal relation, can be better grasped, possibly, in reference to a few entities that make best display of their systemic nature, for example images, works of art, and virtual bodies. This book shows how virtual bodies are ontological hybrids representing a type of entity that has never appeared in the world before. This entity becomes a phenomenon in interactivity and evades the dichotomy between “external” and “internal”; it is neither a cognitive product of the consciousness, nor an image of the mind. The user is well aware of experiencing anotherreality, also in the sense of a paradoxical reduplication of perceptual synthesis. The virtual body-environment is therefore simultaneously external and internal, with virtual bodies-environments to be seen as artificial windows to an intermediary world. In this intermediary world, the space itself is the result of interactivity; the world takes place in the sense or feeling of immersion experienced by the user; and the body, perceived as “other”, takes upon itself the sense of its reality, of its effectiveness, as an imaginary and pathic incision, as a production of desire and emotion, to the point that the feeling of reality conveyed by a virtual environment will rely significantly on how this environment produces emotions in the users.

The essay concerns the notion of interface. From theoretical point of view, interface is a virtual environment develops in the interaction with a user; in this context “virtual” means the dynamic configuration of forces which have the intrinsic tendency of being actualised in a form not entirely pre-existing. The virtual in this case has to do with Aesthetics and its present status as discipline, since it is a field of continuous formal invention and of a particular type of interaction author/user (...) rendered possible by the specific characteristics of the electronic medium.

Through an analysis of some crucial passages from Giovanni Gentile’s Sistema di logica come teoria del conoscere, Filosofia dell’arte, Introduzione alla filosofia and Genesi e struttura della società, the paper discusses the role and significance of the notion of “feeling” in Gentile’s philosophy and offers some insights into the idea of “aesthetic logos”, synthesis of logical immediacy and phenomenological immediacy, exhibition of a radical negativity beyond any conceptual understanding.

L’articolo indaga l’opera di Paolo Rosa e di Studio Azzurro a partire dal suo rilievo politico. L’articolo rielabora il concetto, formulato originariamente da Walter Benjamin ne L’opera d’arte nell’epoca della sua riproducibilità tecnica, di “politicizzazione dell’arte”. Mentre per Benjamin la politicizzazione dell’arte riguarda il movimento di emancipazione delle masse da opporre alla “estetizzazione della politica”, il concetto si presta qui a una nuova interpretazione. Riprendendo il titolo di un saggio scritto da Rosa insieme ad Andrea Balzola, l’articolo mostra come l’arte (...) debba “uscire fuori di sé”. In altre parole, l’artista deve abbandonare le consuete modalità della creazione e della fruizione, per istituire nuove condizioni di interazione all’interno degli ambienti prodotti attraverso la creazione di immagini. In questo modo, l’opera di Rosa e Studio Azzurro recupera in una nuova accezione l’“aura” dell’opera d’arte. (shrink)

Il fil rouge che lega le quattro sezioni del volume, che raccoglie le relazioni presentate al convegno internazionale Interactive Imagination (Roma, 6-8 giugno 2016), con l’aggiunta di contributi dei curatori e di studiosi che pure vi hanno partecipato, è la nozione di immaginazione, investigata da diverse prospettive teorico-filosofiche, correlata a quella di ambiente, anch’essa approfondita sotto diversi aspetti. Il tema mediale compare, talvolta esplicito talvolta in filigrana, con sfacce...

The theme of Aesthetics in Present Future concerns the new chances the arts have and the deep changes they are undergoing, due to the new media, and the digital world in which we are growingly immersed. That this world is to be understood from an aesthetic point of view, become clear if we think of how much of what we produce, and observe and study is offered through images in particular and perceptual means in general.

Esta es la versión escrita de una entrevista realizada a Eugenio Bulygin, profesor emérito de Filosofía del Derecho (UBA), con respecto a quien toda presentación podría resultar o bien imcompleta o bien superflua. -/- Nuestra intención al realizar esta entrevista fue indagar acerca de las respuestas que dieron a esos interrogantes las personas que, en ese momento, ocuparon posiciones de toma de decisión en la Facultad de Derecho de la UBA. La elección del entrevistado, Eugenio Bulygin, no podría haber sido (...) mejor. No solo por su lucidez y por haber ocupado un puesto de suma importancia en la transición democrática, el de Decano Normalizador, sino porque, además, ha estado siempre, antes y después de la transición, estrechamente vinculado a la Facultad, de modo que provee un testimonio invaluable de sus transformaciones a lo largo de la segunda mitad del S.

Un’eccellente chiave di lettura di questo ampio e articolato lavoro proviene dal riferimento iniziale che, al fine di chiarire le ragioni della scelta del titolo, Diodato fa alla centralità del suo interesse per l’aisthesis e per il “corpo vivo” nella sua interazione con i corpi-immagine. L’esperienza dell’immersione nei mondi virtuali ci pone infatti di fronte alla necessità di interrogarci sia intorno al nostro rapporto sensoriale e rappresentazionale con la nuova “realtà” sia intorno al su...

We show the intimate relationship between McNaughton Theorem and the Chinese Remaindner Theorem for MV-algebras. We develop a very short and simple proof of McNaughton Theorem. The arguing is elementary and right out of the definitions. We exhibit the theorem as just an instance of the Chinese theorem. Since the variety of MV-algebras is arithmetic, the Chinese theorem holds for MV-algebras. However, to make this paper self-contained and entirely elementary, we include a simple proof of this theorem inspired in (...) class='Hi'>Ferraioli and Lettieri (Math Logic Q 1:27–43, 2011).

This work suggests how much human sciences can learn from a booklet almost all cultures know, The Little Prince. It stimulates to read them in their anthropological aspects of behavior facing alterity, highlighting its value without proposing it as educational element to homogenize the different. The reflection is thus focused on the demolishing and lasting effects of European culture during its colonization of American and African people. The contribution ends with Ferraioli and De Vitoria's considerations on a society based (...) on the axiom of the free circulation of men and goods, and the legitimization of thinking given by natural law.

A fronte di rapide trasformazioni geo-politiche globali, il tema dei diritti fondamentali - quale sia la loro struttura, quali debbano considerarsi tali, in qual modo li si possa garantire, quale il rapporto con la cittadinanza e la democrazia - acquista sempre maggiore rilevanza nella discussione pubblica. Luigi Ferraioli propone su questi problemi un'originale e innovativa riflessione, suscitando un dibattito in cui si coniugano rigore scientifico e passione civile.
