Gianni Vattimo, a leading philosopher of the continental school, has always resisted autobiography. But in this intimate memoir, the voice of Vattimo as thinker, political activist, and human being finds its expression on the page. With Piergiorgio Paterlini, a noted Italian writer and journalist, Vattimo reflects on a lifetime of politics, sexual radicalism, and philosophical exuberance in postwar Italy. Turin, the city where he was born and one of the intellectual capitals of Europe (also the city in which Nietzsche (...) went mad), forms the core of his reminiscences, enhanced by fascinating vignettes of studying under Hans Georg Gadamer, teaching in the United States, serving as a public intellectual and interlocutor of Habermas and Derrida, and working within the European Parliament to unite Europe. Vattimo's status as a left-wing faculty president paradoxically made him a target of the Red Brigades in the 1970s, causing him to flee Turin for his life. Left-wing terrorism did not deter the philosopher from his quest for social progress, however, and in the 1980s, he introduced a daring formulation called "weak thought," which stripped metaphysics, science, religion, and all other absolute systems of their authority. Vattimo then became notorious both for his renewed commitment to the core values of Christianity (he was trained as a Catholic intellectual) and for the Vatican's denunciation of his views. Paterlini weaves his interviews with Vattimo into an utterly candid first-person portrait, creating a riveting text that is destined to become one of the most compelling accounts of homosexuality, history, politics, and philosophical invention in the twentieth century.

The present paper gives a topological solution to representability problems related to multi-utility, in the field of Decision Theory. Necessary and sufficient topologies for the existence of a semicontinuous and finite Richter–Peleg multi-utility for a preorder are studied. It is well known that, given a preorder on a topological space, if there is a lower semicontinuous Richter–Peleg multi-utility, then the topology of the space must be finer than the Upper topology. However, this condition fails to be sufficient. Instead of search (...) for properties that must be satisfied by the preorder, we study finer topologies which are necessary or/and sufficient for the existence of semicontinuous representations. We prove that Scott topology must be contained in the topology of the space in case there exists a finite lower semicontinuous Richter–Peleg multi-utility. However, the existence of this representation cannot be guaranteed. A sufficient condition is given by means of Alexandroff’s topology, for that, we prove that more order implies less Alexandroff’s topology, as well as the converse. Finally, the paper is implemented with a topological study of the maximal elements. (shrink)

Econophysics is a branch of economics that applies concepts and methods from physics to the financial markets. This article focuses on the approaches to quantum finance developed by Kirill Ilinski and Belal E. Baaquie to deal with the uncertainty characterizing financial time series. Allegedly, their models rest on a formal analogy between quantum mechanics and finance. In order to evaluate them, we raise the question what is really quantum in quantum econophysics. We then argue that the supposed analogy breaks in (...) an important manner, which is relevant to explain the empirical success of the proposed models. (shrink)

Elizabeth Taylor: The Queen and I is a remarkable collection of Gianni Bozzacchi’s photographs of Elizabeth Taylor, most of them previously unpublished, capturing her as a film star, a woman, and a personal friend.

This article offers a detailed analysis of Ilyenkov’s conception of the relationship between the logical and the historical. It posits that Ilyenkov, by overcoming the theoretical impasses of mainstream Soviet Marxism, was the first thinker to recognize the centrality of this relationship in dialectics. Through a brief overview of the official conception of Diamat, I explain that the latter broadly understood the relation of the logical and the historical in a rather superficial way. I then argue that Ilyenkov’s approach to (...) dialectics as the ascent from the abstract to the concrete, combined with his research orientation towards the method of Marx’s Capital and his reevaluation of Hegel’s philosophy led him to a much deeper understanding of the inner unity of the method of ascent from the abstract to the concrete and the relation of the logical and the historical. In reconstructing Ilyenkov’s analysis on this matter, I explain how the unfolding of the categories throughout the ascent from the abstract to the concrete is inextricably intertwined with the relation of the logical and the historical. Therefore, the article concludes by arguing that Ilyenkov’s analysis marks a significant advance in the understanding of dialectics in the history of Marxism, and a core aspect of this deeper understanding is his systematic approach to the relationship of the logical and the historical.

In this paper we use the framework of generalized probabilistic theories to present two sets of basic assumptions, called axioms, for which we show that they lead to the Hilbert space formulation of quantum mechanics. The key results in this derivation are the co-ordinatization of generalized geometries and a theorem of Solér which characterizes Hilbert spaces among the orthomodular spaces. A generalized Wigner theorem is applied to reduce some of the assumptions of Solér’s theorem to the theory of symmetry in (...) quantum mechanics. Since this reduction is only partial we also point out the remaining open questions. (shrink)

Despite the growth of philosophy for/with children over the last five decades, its legitimacy remains contested. Key themes within the P4C literature are the potential learning outcomes for children as well as possible personal and professional development benefits for those that teach it. The literature on the former, while extensive, presents a mixed picture and highlights the challenges inherent in determining the impact of P4C on learning outcomes. The literature on the latter, while little explored, may provide valuable insights for (...) teacher professional development. Unlike much of the literature, this paper examines the impact of P4C from the P4C educators’ perspective. The paper presents the findings from a pilot study of volunteer teachers with the Primary Ethics program in Sydney, Australia. Two key findings emerged. First, ethics teachers felt they were making a material and positive difference to the children they taught, which included: the development of critical thinking and reasoning skills; increased confidence to express themselves; and enjoyment derived from class discussions. Second, teachers that use a philosophical and a community of inquiry approach with their students may themselves become more reflective and engage in critical thinking and ethical reasoning.

What has been the fate of Christianity since Nietzsche's famous announcement of the "death of God"? What is the possibility of religion, specifically Christianity, thriving in our postmodern era? In this provocative new book, Gianni Vattimo, leading Italian philosopher, politician, and framer of the European constitution, addresses these critical questions. When Vattimo was asked by a former teacher if he still believed in God, his reply was, "Well, I believe that I believe." This paradoxical declaration of faith serves as (...) the foundation for a brilliant exposition on Christianity in the new millennium--an age characterized by a deep uncertainty of opinion--and a personal account of how Vattimo himself recovered his faith through Nietzsche and Heidegger. He first argues that secularization is in fact the fulfillment of the central Christian message, and prepares us for a new mode of Christianity. He then explains that Nietzsche's thesis concerns only the "moral god" and leaves room for the emergence of "new gods." Third, Vattimo claims that the postmodern condition of fragmentation, anti-Eurocentrism, and postcolonialism can be usefully understood in light of Joachim of Fiore's thesis concerning the "Spiritual Age" of history. Finally, Vattimo argues for the idea of "weak thought." Because philosophy in the postmetaphysical age can only acknowledge that "all is interpretation," that the "real" is always relative and not the hard and fast "truth" we once thought it to be, contemporary thought must recognize itself and its claims as "weak" as opposed to "strong" foundationalist claims of the metaphysical past. Vattimo concludes that these factors make it possible for religion and God to become a serious topic for philosophy again, and that philosophy should now formally engage religion. (shrink)

It is well known that interval orders are particularly interesting in decision theory, since they are reflexive, complete and nontransitive binary relations which may be fully represented by means of two real-valued functions. In this paper, we discuss the existence of a pair of nonnegative, positively homogeneous and semicontinuous real-valued functionals representing an interval order on a real cone in a topological vector space. We recover as a particular case a result concerning the existence of a nonnegative, positively homogeneous and (...) continuous utility functional for a complete preorder on a real cone in a topological vector space.

We show that modal logics characterized by a class of frames satisfying the insertion property are suitable for Reiter's default logic. We refine the canonical fix point construction defined by Marek, Schwarz and Truszczyński for Reiter's default logic and thus we addrress a new paradigm for nonmonotonic logic. In fact, differently from the construction defined by these authors. we show that suitable modal logics for such a construction must indeed contain K D4. When reflexivity is added to the modal logic (...) used for the fix point construction then we come to the Marek Schwarz and Truszczyński framework for Reiter's default logic. Our framework, in fact, is appropriate also to the family of modal logics in between S4 and S4f. If, instead, reflexivity is dropped, then we show that a new family of modal logics is gained, namely the modal logics in between KD4 and KD4Z. The upper bound can be extended to the modal logic KD4LZ whenever the propositional language taken into account is finite. (shrink)

Early diagnosis of leaf diseases is a fundamental tool in precision agriculture, thanks to its high correlation with food safety and environmental sustainability. It is proven that plant diseases are responsible for serious economic losses every year. The aim of this work is to study an efficient network capable of assisting farmers in recognizing pear leaf symptoms and providing targeted information for rational use of pesticides. The proposed model consists of a multioutput system based on convolutional neural networks. The deep (...) learning approach considers five pretrained CNN architectures, namely, VGG-16, VGG-19, ResNet50, InceptionV3, MobileNetV2, and EfficientNetB0, as feature extractors to classify three diseases and six severity levels. Computational experiments are conducted to evaluate the model on the DiaMOS Plant dataset, a self-collected dataset in the field. The results obtained confirm the robustness of the proposed model in automatically extracting the discriminating features of diseased leaves by adopting the multitasking learning paradigm. (shrink)

The aim of this critical note is to discuss Heraclitus' use of analogy as a pattern of thought not only with argumentative value but also ontological and epistemological status. Heraclitus' analogy is of two kinds and is expressed in the use of the adverbs ὥσπερ ("as") and ὅκωσπερ ("just as"). The first is used as an explanatory device, while the second denotes the ontological homogeneity of logos. Analogy reveals not only the inherent opposition of logos in each single thing, but (...) also the interdependent common interrelation between things. (shrink)

Il tema dell'anima come dimensione interna e come essenza dell'io, come campo di battaglia in cui costantemente vengono alla luce i suoi innumerevoli conflitti interni, tra forze o energie che si combattono tra di loro in un continuo scontro, in una lotta che si risolve a vantaggio di chi esercita un maggior dominio o potere, costituiscono, nel loro complesso, il panorama in cui si muove la riflessione: da una parte, la ragione (a cui spetta il comando), dall'altra, le svariate passioni, (...) i desideri disordinati (che tendono, invece, al pieno controllo dell'anima) legati al riconoscimento pubblico, all'autoaffermazione (ambizione, fama, onore, potere, ricchezza) assieme ai piaceri insaziabili (del cibo, del bere, dei sensi). L’esito finale di questa costante lotta non è mai scontato, in quanto il vincitore non è sempre lo stesso. Spesso, infatti, i sensi (contro ogni razionalità, contro ogni ragione) sembrano trascinarci in ogni direzione e da ciò risulta chiaro che, in molte occasioni, non è affatto la ragione ad avere il potere e il comando sulla nostra anima e sulla nostra condotta di vita, come invece dovrebbe. Dalla riflessione sulle dinamiche di questo conflitto all'interno di ogni individuo, conflitto che si estende all'esterno, fino a rispecchiarsi in egual modo nella città, si approda ad un programma di ricostruzione dell'armonia dell'anima e della città, dell'individuo e della comunità, dell'"interno" e dell'"esterno", dando forma ad una giusta, ordinata e armonica gerarchia di comando che conduce, in ultimo, al loro pieno benessere, e quindi alla loro felicità.

According to modems interpreters, there are two differents accounts of the doctrine of predicables in Aristotle's Topics: the exclusive and the inclusive one. The shift between these two accounts it is generally explained with genetic criteria. This paper shows that not all the contradictions found between book A of Topics and its central books are real, and gives a non genetic explanatión of the authentic incoherences. It is also shown that in the whole text of Topics there is no trace (...) of an inclusive account of genus. (shrink)

The first book-length philosophical study on the Presocratic influences in Plotinus’ Enneads.

This essay aims to emphasize the link between the feelings of insecurity and uncertainty that spreads in contemporary societies and the rise of populism. The triumph of globalization, the crisis of welfare state caused a social atmosphere of insecurity and environmental fear: in this situation the citizens mostly fight for individual security and political leaders suggest a simple and schematic conception of democracy.

Since the earliest formalisation of default logic by Reiter many contributions to this appealing approach to nonmonotonic reasoning have been given. The different formalisations are here presented in a general framework that gathers the basic notions, concepts and constructions underlying default logic. Our view is to interpret defaults as special rules that impose a restriction on the juxtaposition of monotonic Hubert-style proofs of a given logicL. We propose to describe default logic as a logic where the juxtaposition of default proofs (...) is subordinate to a restriction condition . Hence a default logic is a pair (L, ) where properties of the logic , like compactness, can be interpreted through the restriction condition . Different default systems are then given a common characterization through a specific condition on the logicL. We also prove cumulativity for any default logic (L, ) by slightly modifying the notion of default proof. We extend, in fact, the language ofL in a way close to that followed by Brewka in the formulation of his cumulative default system. Finally we show the existence of infinitely many intermediary default logics, depending on and called linear logics, which lie between Reiter's and ukaszewicz' versions of default logic. (shrink)

If utopias in the western cultural tradition owe their model of ideal, final, unitary order to the objective basis of metaphysics, have they not, like metaphysics, undergone a dissolution in Heidegger’s sense of Verwindung? Insofar as the very notion of unity, like that of an ultimate metaphysical foundation, now reveals its violence and will to domination and as we are interested instead in thinking utopia as a ‘project for emancipation’, the author suggests replacing the unity that was hitherto characteristic of (...) utopia with a multiplicity that is defended as a value and not as a phase of ‘confusion’ to be overcome.
