An analysis of three pictorial works by Ugo Nespolo is put forward: "Barbe posticce" (1977); "Guardar Manzoni" (1974); "Il museo: Fontana" (1975). It is claimed that such works embody meditations on the concept and the varieties of representation, that they prompt critical reflections on the role of museums in art-making, and that they suggest an alternative route to that of the 'dematerialization' of the art object for the understanding of contemporary art.
We study the decidability problem for metric and layered temporal logics. The logics we consider are suitable to model time granularity in various contexts, and they allow one to build granular temporal models by referring to the "natural scale" in any component of the model and by properly constraining the interactions between differently-grained components. A monadic second-order language combining operators such as temporal contextualization and projection, together with the usual displacement operator of metric temporal logics, is considered, and the theory (...) of finitely-layered metric temporal structures is shown to be decidable.

Cet article s’attache à comprendre si les cyrénaïques étaient susceptibles d’être attaqués moyennant l’objection d’inactivité et, si oui, comment ils auraient pu essayer d’y répondre et quel type de vision morale ils auraient pu essayer de défendre. En traitant de ces questions, j’évaluerai la légitimité de l’interprétation du scepticisme cyrénaïque offerte par Jules Vuillemin. Je confirmerai ainsi la plausibilité de son interprétation et développerai en même temps l’exploration de la nature et de la portée de la philosophie cyrénaïque.
The article examines the philosophical works of Ugo Perone. It explores the different aspects of temporality and spatiality inherent in Perone's understanding of time in the figure of threshold, and analyzes the notion of the so-called political present. Also investigated are the claims of Perone about the significance of politics and the public space on the human life.
Studies on the 1616 and 1633 actions brought against Galilei by the Index and the Inquisition generally presumed that part of the documentation was still to be unveiled. This assumption was frequently accompanied by the hypothesis that some available documents were forgeries, merely composed to justify the 1633 condemnation. New documents from the Archive of the Roman Inquisition, including a censure of Saggiatore, official acts concerning the public dissemination of the verdict, and applications for permission to read Galilei¹s works, show (...) that the 1984 edition of his trial was not exhaustive. It is argued, however, that these documents were not concealed intentionally by the Holy Office and their not being found so far has been mainly due to the poor organisation of the Archive. Gianfranco Catelli, Gouhier e la cosiddetta dottrina della terza nozione primitiva In questo studio non si condivide l’opinione, dominante per molti decenni, che il cosiddetto dualismo cartesiano sia dovuto ad un “malinteso”, che può chiamarsi originario, dato che a rimanerne coinvolti furono alcuni tra i primi seguaci della filosofia di Cartesio. Una presa di posizione, questa, che, già sviluppata in altri precedenti lavori, viene qui riproposta relativamente a H. Gouhier, lo studioso che più di ogni altro, con ricchezza di documenti e sottigliezza di analisi interpretative, ha sostenuto la tesi del “malinteso” e ha individuato nella dottrina della terza nozione primitiva la spiegazione autenticamente cartesiana del rapporto sussistente tra anima e corpo. Una interpretazione di cui nel presentge studio si mostra tutta la debolezza, soprattutto se la si considera alla luce dell’altra dottrina, anch’essa cartesiana, ma di gran lunga più articolata, che fa del rapporto tra anima e corpo un nesso da spiegarsi in analogia al rapporto che nel linguaggio intercorre tra il segno e il suo significato.

This work deals with the exponential fragment of Girard's linear logic without the contraction rule, a logical system which has a natural relation with the direct logic . A new sequent calculus for this logic is presented in order to remove the weakening rule and recover its behavior via a special treatment of the propositional constants, so that the process of cut-elimination can be performed using only “local” reductions. Hence a typed calculus, which admits only local rewriting rules, can be (...) introduced in a natural manner. Its main properties — normalizability and confluence — has been investigated; moreover this calculus has been proved to satisfy a Curry-Howard isomorphism with respect to the logical system in question.

The Cyrenaic school of philosophy (named after its founder Aristippus’ native city of Cyrene in North Africa) flourished in the fifth and fourth centuries BCE. Ugo Zilioli’s book provides the first book-length introduction to the school in English. The book begins by introducing the main figures of the Cyrenaic school beginning with Aristippus and by setting them into their historical context. Once the reader is familiar with those figures and with the genealogy of the school, the book offers an overview (...) of ancient and modern interpretations of the Cyrenaics, to provide readers with alternative accounts of the doctrines they endorsed and of the role they played in the context of ancient thought. Finally, the book offers a reconstruction of Cyrenaic philosophy and shows how the ethical side of their speculation connected with the epistemology and ontology they endorsed and that, as a result, the Cyrenaics were able to offer a quite sophisticated philosophy. Indeed, Zilioli demonstrates that they represented, in ancient philosophy, an important and original metaphysical position and alternative to the kind of realism endorsed by Plato and Aristotle.

Protagoras was an important Greek thinker of the fifth century BC, the most famous of the so called Sophists, though most of what we know of him and his thought comes to us mainly through the dialogues of his strenuous opponent Plato. In this book, Ugo Zilioli offers a sustained and philosophically sophisticated examination of what is, in philosophical terms, the most interesting feature of Protagoras' thought for modern readers: his role as the first Western thinker to argue for relativism. (...) Zilioli relates Protagoras' relativism with modern forms of relativism, in particular the 'robust relativism' of Joseph Margolis, gives an integrated account both of the perceptual relativism examined in Plato's Theaetetus and the ethical or social relativism presented in the first part of Plato's Protagoras and offers an integrated and positive analysis of Protagoras' thought, rather than focusing on ancient criticisms and responses to his thought. This is a deeply scholarly work which brings much argument to bear to the claim that Protagoras was and remains Plato's subtlest philosophical enemy. (shrink)
