Apocalypse Postponed: Essays byUmberto Eco.Umberto Eco -2000 - Indiana University Press.detailsAn erudite and witty collection ofUmberto Eco's essays on mass culture from the 1960s through the 1980s, including major pieces which have not been translated into English before. The discussion is framed by opposing characterizations of current intellectuals as apocalyptic and opposed to all mass culture, or as integrated intellectuals, so much a part of mass culture as to be unaware of serving it. Organized in four main parts, "Mass Culture: Apocalypse Postponed," "Mass Media and the Limits of (...) Communication," "The Rise and Fall of Counter-Cultures," and "In Search of Italian Genius," Eco looks at a variety of topics and cultural productions, including the world of Charlie Brown, distinctions between highbrow and lowbrow, the future of literacy, Chinese comic strips, whether countercultures exist, Fellini's Ginger and Fred, and the Italian genius industry.

Belief or Nonbelief?: A Confrontation.Umberto Eco &Carlo Maria Martini -2012 - Arcade.detailsOne is the beloved author of The Name of the Rose, a celebrated scholar, philosopher, and self-declared secularist; the other is a preeminent clergyman and a respected expert on the New Testament. In this intellectually stimulating dialogue, often adversarial but always amicable, these two great men, who stand on opposite sides of the church door, discuss some of the most controversial issues of our day, including the apocalypse, abortion, women in the clergy, and ethics. As we voyage onward into the (...) new millennium, they frame a debate about matters that have already begun to rage, always aware of the gulf between belief and nonbelief that separates them, constantly probing and challenging, but also respectful of the other’s viewpoint. For believers and nonbelievers alike, the result is both edifying and illuminating. “Their correspondence,” writes Professor Harvey Cox in his introduction, “lifts the possibility of intelligent conversation on religion to a new level.”.

An infinity of super-Belnap logics.Umberto Rivieccio -2012 -Journal of Applied Non-Classical Logics 22 (4):319-335.detailsWe look at extensions (i.e., stronger logics in the same language) of the Belnap–Dunn four-valued logic. We prove the existence of a countable chain of logics that extend the Belnap–Dunn and do not coincide with any of the known extensions (Kleene’s logics, Priest’s logic of paradox). We characterise the reduced algebraic models of these new logics and prove a completeness result for the first and last element of the chain stating that both logics are determined by a single finite logical (...) matrix. We show that the last logic of the chain is not finitely axiomatisable. (shrink)
Fragments of Quasi-Nelson: The Algebraizable Core.Umberto Rivieccio -2022 -Logic Journal of the IGPL 30 (5):807-839.detailsThis is the second of a series of papers that investigate fragments of quasi-Nelson logic (QNL) from an algebraic logic standpoint. QNL, recently introduced as a common generalization of intuitionistic and Nelson’s constructive logic with strong negation, is the axiomatic extension of the substructural logic |$FL_{ew}$| (full Lambek calculus with exchange and weakening) by the Nelson axiom. The algebraic counterpart of QNL (quasi-Nelson algebras) is a class of commutative integral residuated lattices (a.k.a. |$FL_{ew}$|-algebras) that includes both Heyting and Nelson algebras (...) and can be characterized algebraically in several alternative ways. The present paper focuses on the algebraic counterpart (a class we dub quasi-Nelson implication algebras, QNI-algebras) of the implication–negation fragment of QNL, corresponding to the connectives that witness the algebraizability of QNL. We recall the main known results on QNI-algebras and establish a number of new ones. Among these, we show that QNI-algebras form a congruence-distributive variety (Cor. 3.15) that enjoys equationally definable principal congruences and the strong congruence extension property (Prop. 3.16); we also characterize the subdirectly irreducible QNI-algebras in terms of the underlying poset structure (Thm. 4.23). Most of these results are obtained thanks to twist representations for QNI-algebras, which generalize the known ones for Nelson and quasi-Nelson algebras; we further introduce a Hilbert-style calculus that is algebraizable and has the variety of QNI-algebras as its equivalent algebraic semantics.

Nelson Conuclei and Nuclei: The Twist Construction Beyond Involutivity.Umberto Rivieccio &Manuela Busaniche -2024 -Studia Logica 112 (5):1123-1161.detailsRecent work by Busaniche, Galatos and Marcos introduced a very general twist construction, based on the notion of _conucleus_, which subsumes most existing approaches. In the present paper we extend this framework one step further, so as to allow us to construct and represent algebras which possess a negation that is not necessarily involutive. Our aim is to capture the main properties of the largest class that admits such a representation, as well as to be able to recover the well-known (...) cases—such as _(quasi-)Nelson algebras_ and _(quasi-)N4-lattices_—as particular instances of the general construction. We pursue two approaches, one that directly generalizes the classical Rasiowa construction for Nelson algebras, and an alternative one that allows us to study twist-algebras within the theory of residuated lattices.

First-Order Logic Formalisation of Impossibility Theorems in Preference Aggregation.Umberto Grandi &Ulle Endriss -2013 -Journal of Philosophical Logic 42 (4):595-618.detailsIn preference aggregation a set of individuals express preferences over a set of alternatives, and these preferences have to be aggregated into a collective preference. When preferences are represented as orders, aggregation procedures are called social welfare functions. Classical results in social choice theory state that it is impossible to aggregate the preferences of a set of individuals under different natural sets of axiomatic conditions. We define a first-order language for social welfare functions and we give a complete axiomatisation for (...) this class, without having the number of individuals or alternatives specified in the language. We are able to express classical axiomatic requirements in our first-order language, giving formal axioms for three classical theorems of preference aggregation by Arrow, by Sen, and by Kirman and Sondermann. We explore to what extent such theorems can be formally derived from our axiomatisations, obtaining positive results for Sen’s Theorem and the Kirman-Sondermann Theorem. For the case of Arrow’s Theorem, which does not apply in the case of infinite societies, we have to resort to fixing the number of individuals with an additional axiom. In the long run, we hope that our approach to formalisation can serve as the basis for a fully automated proof of classical and new theorems in social choice theory. (shrink)

History of beauty.Umberto Eco &Alastair McEwen (eds.) -2005 - New York: Rizzoli.detailsWhat is beauty? What is art? What is taste and fashion? Is beauty something to be observed coolly and rationally or is it something dangerously involving? So beginsUmberto Eco's intriguing journey into the aesthetics of beauty, in which he explores the ever-changing concept of the beautiful from the ancient Greeks to today. While closely examining the development of the visual arts and drawing on works of literature from each era, Eco broadens his enquiries to consider a range of (...) concepts, including the idea of love, the unattainable woman, natural inspiration versus numeric formulas, and the continuing importance of ugliness, cruelty, and even the demonic. Professor Eco takes us from classical antiquity to the present day, dispelling many preconceptions along the way and concluding that the relevance of his research is urgent because we live in an age of great reverence for beauty, "an orgy of tolerance, the total syncretism and the absolute and unstoppable polytheism of Beauty." In this, his first illustrated book, Professor Eco offers a layered approach that includes a running narrative, abundant examples of painting and sculpture, and excerpts from writers and philosophers of each age, plus comparative tables. A true road map to the idea of beauty for any reader who wishes to journey into this wonderful realm with Eco's nimble mind as guide. (shrink)

Promoting online collaborative learning on moodle platform with the “quick chat” plugin.Umberto Dello Iacono -2022 -Human Review. International Humanities Review / Revista Internacional de Humanidades 11 (3):1-10.detailsIn recent years, several Vygotskian computer-based learning activities (VCBLAs) were designed in the context of (mathematics) education and implemented on Moodle platform. However, Moodle does not allow users to visualize all chats on a single browser page, and they are forced to open multiple browser windows and switch among them very frequently. This paper describes the features of a plugin for Moodle, called “Quick Chat,” which allows to manage in a single browser window both the narrative flow of a VCBLA (...) and all chats. Some results of an experimentation with PhD students, engaged in solving two mathematical tasks, are shown. (shrink)
