Originariamente letto a una conferenza nel marzo 1907, questo breve saggio non e ne una biografia di Giordano Bruno ne un'esposizione del suo pensiero, ma un'analisi del ruolo da lui ricoperto nella cultura del tempo e delle ragioni del suo scontro con le autorita ecclesiastiche. Rifiutando le semplificazioni di un Giordano Bruno ateo o anticlericale, Giovanni Gentile espone una sua personale interpretazione della vita del pensatore nolano, considerandolo non gia un "martire del libero pensiero," quanto piuttosto, al pari (...) di Socrate, un "martire della filosofia." Ne scaturisce il ritratto di un Bruno avverso non alla religione in se ma alla superstizione, e fautore, in anticipo sui tempi, della separazione tra fede e scienza.". (shrink)

Abstract: Il testo viene pubblicato per gentile concessione della casa editrice ESI ed e’ tratto dal libro di Stefano Ulliana “Il concetto creativo e dialettico dello Spirito nei Dialoghi Italiani di Giordano Bruno. Il confronto con la tradizione neoplatonico-aristotelica: il testo bruniano De l’Infinito, Universo e mondi”, Edizioni Scientifiche Italiane, Napoli, 2003. -/- Le argomentazioni presentate ne Il concetto creativo e dialettico dello Spirito nei Dialoghi Italiani di Giordano Bruno (Il confronto con la tradizione neoplatonico-aristotelica: il testo bruniano (...) De l’Infinito, Universo e mondi) costituiscono le conclusioni ultime e definitive di un lavoro di ricerca che ha investito l’insieme dei Dialoghi Italiani, riuscendo a reperire ed a far emergere quello che pare il nucleo più profondo ed importante—il vero e proprio elevato fondamento—della speculazione bruniana: la presenza attiva di un concetto triadico teologico-politico—il Padre, il Figlio e lo Spirito della tradizione trinitaria cristiana—però riformulato attraverso il capovolgimento rivoluzionario di questa stessa tradizione, attuato attraverso il concetto creativo e dialettico dell’infinito. In questo modo la stessa tradizione platonica pare subire una trasformazione essenziale, abbandonando qualunque forma di alienazione e negazione, per riaprirsi invece verso soluzioni che paiono riprendere moniti ed osservazioni suscitati dalle prime, grandi e maestose, speculazioni dei filosofi presocratici. Parmenide, Eraclito ed Empedocle sembrano rivivere nei testi bruniani, riproponendo una soluzione ben diversa a quei nodi e problemi teoretico-pratici—fondamentale il rapporto Uno-molti e tutto ciò che da esso consegue, sia sul piano naturale che politico—apparentemente risolti e codificati dal pensiero postsocratico, prima platonico e poi aristotelico. L’inscindibilità del principio di libertà (la figura teologica del Padre) ed eguaglianza (il Figlio), attraverso il richiamo alla fonte amorosa infinita ed universale (lo Spirito), consente alla riflessione bruniana di presentare per la prima volta nel panorama filosofico mondiale di tutti i tempi la possibilità di salvaguardare sia l’aspetto creativo naturale, che la diversità politica, presentando nel contempo un concetto di ragione capace di esprimere un movimento infinito sempre aperto ed attento alla molteplicità. In questa liberazione della potenza e della volontà dalle strettoie ordinate e gerarchiche della tradizione il pensiero e la riflessione di Giordano Bruno danno inizio alla modernità, ripresentandosi quale mirabile soluzione ogni qual volta potere e violenza paiono assestarsi e reciprocamente incrementarsi, in un circolo apparentemente indistruttibile. -/- Allora i capitoli di questo libro—attraverso l’analisi di concetti importanti nella filosofia bruniana, quali quelli del desiderio e dell’immaginazione, della materia e della ragione—riattraversano la storia della definizione filosofica delle entità reali più importanti—Dio, Natura, Ragione, Uno—per mostrare un’opposizione fondamentale: l’opposizione fra la fusione speculativa apportata dal pensiero neoplatonico-aristotelico (antico, moderno e contemporaneo), attenta alla difesa della necessità ordinata di un mondo unico, e la liberazione speculativo-pratica bruniana, attenta a far rivivere la coscienza dell’infinito, in noi e fuori di noi. -/- English Abstract: The arguments that have been presented in this essay, which are part of the book ‘The creative and dialectical concept of the Spirit in the Italian Dialogues of Jordanus Brunus. The comparison with the neoplatonic-Aristotelian tradition: the brunian text De l’Infinito, Universo e mondi’, constitute the ultimate and definitive conclusions of a body of research that has mainly focused on Bruno’s work “Dialoghi Italiani”. This research has managed to rise the deepest and most important core of the true foundation of Giordano Bruno’s speculative thinking—the active presence of a triadic theological-political concept of the Father, the Son and the Spirit of Christian tradition. However, this triad has also been reformulated through the revolutionary overturning of this tradition and realized through a creative and dialectical concept of the infinite. In this way the same Platonic tradition seems to undergo an essential transformation by abandoning any form of alienation and negation and indeed to open itself to recover those warnings and observations that the first great speculative thoughts of the Presocratics philosophers brought about. Parmenides, Heraclitus and Empedocles seem to come to life again in Bruno’s essays by proposing a different solution to those theoretical and practical problems such as the fundamental relation between One-many and what it can represent either at the natural level or at the political level which have been apparently solved and codified in the Platonic and Aristotelian thought. -/- The indissolubility of the freedom principle (the theological character of the Father) and equality (the Son), through the use of the loving, infinite and universal source (the Spirit), allows Bruno’s reflection to present for the first time in the entire philosophical tradition the possibility of safeguarding the creative aspect as well as the political diversity. He achieves this by showing a concept of reason which is able to express the infinite movement that it is always open and measured (careful) towards the multiplicity. In this release of power and will from the ordered and hierarchical paths of the philosophy tradition, Bruno’s thought gave birth to Modernity. (shrink)

Il filosofo e la passione per il “gentil sesso”.

Benedetto Croce was a keen reader of the Italian works of Giordano Bruno when Giovanni Gentile published the Dialoghi metafisici e morali in 1907-1908. Just like his mentor Francesco De Sanctis, Croce sees Bruno as "a great thinker" and "a great writer". What he attaches great value to above all is Bruno as a philosopher deeply engaged in distinguishing between science and philosophy and combating the Aristotelians of the Renaissance. He used Bruno in his own fight (...) against the "Aristotelians" of his age: the Neo-Kantians. In his interpretation of the Italian Renaissance as the age of rationalism, whose main thread was soon broken, Croce puts Bruno and Campanella among the «few scattered and scared apostles of the future» who continued to weave the thread of rationality, later taken up by Vico and Giannone and, finally, by the Italian Risorgimento, starting with the Neapolitan patriots of 1799. When he defined the Italian Renaissance as the historical age of the emersion of rationality and of a true break the tradition, Croce made use of the fundamental intuition of Spaventa and of some of the latter’s disciples. They had stressed in the name of Bruno the sharp break between the Middle Ages and Renaissance philosophy while Croce here came closest to the philosopher from Nola, who had made a trenchant critique of the biblical myth of the "golden age".

The aim of the paper is to argue that all—or almost all—logical rules have exceptions. In particular, it is argued that this is a moral that we should draw from the semantic paradoxes. The idea that we should respond to the paradoxes by revising logic in some way is familiar. But previous proposals advocate the replacement of classical logic with some alternative logic. That is, some alternative system of rules, where it is taken for granted that these hold without exception. (...) The present proposal is quite different. According to this, there is no such alternative logic. Rather, classical logic retains the status of the ‘one true logic’, but this status must be reconceived so as to be compatible with (almost) all of its rules admitting of exceptions. This would seem to have significant repercussions for a range of widely held views about logic: e.g. that it is a priori, or that it is necessary. Indeed, if the arguments of the paper succeed, then such views must be given up. (shrink)

European thought begins with the Greeks. Scientific and philosophic thinking--the pursuit of truth and the grasping of unchanging principles of life--is a historical development, an achievement; and, as Bruno Snell writes in The Discovery of the Mind, nothing less than a revolution. The Greeks did not take mental resources already at their disposal and merely map out new subjects for discussion and investigation. In poetry, drama, and philosophy they in fact discovered the human mind. The stages in man's gradual (...) understanding of himself are revealed in the course of ancient literature from Homer to Virgil. A rational view of the nature of man slowly established itself in the creations of epic and lyric poetry, tragedy and literary criticism, pre-Socratic thought, and early Greek ethics all the way to the discovery of humanitas and the spiritual landscape of Virgil's Arcadia. The Discovery of the Mind is a landmark work in tracing this evolution of consciousness--one of the distinguishing characteristics of the history of man. (shrink)

In this book Bruno Latour brings together these different approaches to provide a lively and challenging analysis of science, demonstrating how social context..

Bruno Latour was once asked : "Do you believe in reality?" This text is an attempt to answer this question.

The aim of this article is to discuss the relations between psychology and politics that guide the action of the different political positions. The starting point will be an analysis of the proposal of the political scientist Mark Lilla to consider the "reactionary spirit" as a position structurally linked to an anti-progressivism, which allows also, by contrast, to discuss the progressive positions. This analysis is anchored in the articulation between politics and temporality, understood here as one of the elements that (...) outline a psychology of conservatism. It helps to redescribe significant features of contemporary political dilemmas, offering, for example, a distinction between the reactionary and the conservative position, as well as defining features of the worldview of the reactionary and, consequently, clues to understanding the rise of the extreme right.

The aim of this paper is to discuss the presence of psychoanalysis in Adorno’s ’Philosophy of the new music’. He draws on the Benjaminian scheme of understanding Baudelaire’s poetry (understood as an elaboration of the shock experiences in life in post-industrial Revolution capitalism), but uses it in music criticism. The works of Schönberg and Stravinsky, the mostimportant composers of two schools of the so-called “new or modern music”, deals with different compositional subjects and their ways of dealing with the shocks (...) of modern life. Both Benjamin and Adorno draw on Freudian theory for the understanding of this notion of shock, in particular his theory of anxiety and trauma. The works of these composers, understood as models of trauma elaboration, offer different ways of reacting to trauma: the identification with the aggressor and resistance. Therein lie elements that help to defend the hypothesis of the centrality of the notion of suffering in Adorno’swork. (shrink)

This paper discusses three generic types or ways of understanding the common good found in the literature, and then describes the implications of the integral common good for seven key practices of humanistic management. In particular, compared to conventional management, an approach to humanistic management based on the integral common good tends to: 1) have institutional mission and vision statements that are developed by multiple stakeholders that emphasize social and ecological well-being ahead of financial well-being; 2) have a strategic orientation (...) that emphasizes collaboration, “minimizer” and “transformer” generic strategies, a Radical Resource Based View, and uses Porter’s five forces as a way to foster collaboration; 3) structure organizations based on experimentation, sensitization, dignification, and participation ; 4) develop control systems based on value loops that seek to enhance the flourishing of multiple stakeholders; 5) emphasize multi-directional multi-stakeholder communication; 6) invite all stakeholders to participate in making decisions, including developing and choosing alternatives; 7) foster leadership based on socialized power, a focus on SMART 2.0 goals, a desire to ensure everyone is treated fairly, and an emphasis on relationships that nurture community and the integral common good. Implications for research and teaching are discussed. (shrink)

This paper argues that we should solve paradoxes for propositions (such as the Russell–Myhill paradox) in essentially the same way that we solve Russellian paradoxes for sets. That is, the standard, iterative approach to sets is extended to include properties, and then the resulting hierarchy of sets and properties is used to construct propositions. Propositions on this account are structured in the sense of mirroring the sentences that express them, and they would seem to serve the needs of philosophers of (...) language and metaphysicians who rely on such propositions. The resulting account has limitations, comparable to those faced by the iterative approach to sets, but it is argued to be in important ways preferable to others that have been proposed. (shrink)

The combination of increased availability of large amounts of fine-grained human behavioral data and advances in machine learning is presiding over a growing reliance on algorithms to address complex societal problems. Algorithmic decision-making processes might lead to more objective and thus potentially fairer decisions than those made by humans who may be influenced by greed, prejudice, fatigue, or hunger. However, algorithmic decision-making has been criticized for its potential to enhance discrimination, information and power asymmetry, and opacity. In this paper, we (...) provide an overview of available technical solutions to enhance fairness, accountability, and transparency in algorithmic decision-making. We also highlight the criticality and urgency to engage multi-disciplinary teams of researchers, practitioners, policy-makers, and citizens to co-develop, deploy, and evaluate in the real-world algorithmic decision-making processes designed to maximize fairness and transparency. In doing so, we describe the Open Algortihms project as a step towards realizing the vision of a world where data and algorithms are used as lenses and levers in support of democracy and development.

Following the book Algebraic Set Theory from André Joyal and leke Moerdijk [8], we give a characterization of the initial ZF-algebra, for Heyting pretoposes equipped with a class of small maps. Then, an application is considered (the effective topos) to show how to recover an already known model (McCarty [9]).

Are there ‘self-referential’ propositions? That is, propositions that say of themselves that they have a certain property, such as that of being false. There can seem reason to doubt that there are. At the same time, there are a number of reasons why it matters. For suppose that there are indeed no such propositions. One might then hope that while paradoxes such as the Liar show that many plausible principles about sentences must be given up, no such fate will befall (...) principles about propositions. But the existence of self-referential propositions would dash such hopes. Further, the existence of such propositions would also seem to challenge the widespread claim that Liar sentences fail to express propositions. The aim of this paper is thus to settle the question–at least given an assumption. In particular, I argue that if propositions are structured, then self-referential propositions exist. (shrink)

The emergence of modern sciences in the seventeenth century profoundly renewed our understanding of Nature. For the last three centuries new ideas of Nature have been continuously developed by theology, politics, economics, and science, especially the sciences of the material world. The situation is even more unstable today, now that we have entered an ecological mutation of unprecedented scale. Some call it the Anthropocene, but it is best described as a new climatic regime. And a new regime it certainly is, (...) since the many unexpected connections between human activity and the natural world oblige every one of us to reopen the earlier notions of Nature and redistribute what had been packed inside. So the question now arises: what will replace the old ways of looking at Nature? This book explores a potential candidate proposed by James Lovelock when he chose the name "Gaia" for the fragile, complex system through which living phenomena modify the Earth. The fact that he was immediately misunderstood proves simply that his readers have tried to fit this new notion into an older frame, transforming Gaia into a single organism, a kind of giant thermostat, some sort of New Age goddess, or even divine Providence. In this series of lectures on "natural religion", Bruno Latour argues that the complex and ambiguous figure of Gaia offers, on the contrary, an ideal way to disentangle the ethical, political, theological, and scientific aspects of the now obsolete notion of Nature. He lays the groundwork for a future collaboration among scientists, theologians, activists, and artists as they, and we, begin to adjust to the new climatic regime. (shrink)

General-elimination harmony articulates Gentzen’s idea that the elimination-rules are justified if they infer from an assertion no more than can already be inferred from the grounds for making it. Dummett described the rules as not only harmonious but stable if the E-rules allow one to infer no more and no less than the I-rules justify. Pfenning and Davies call the rules locally complete if the E-rules are strong enough to allow one to infer the original judgement. A method is given (...) of generating harmonious general-elimination rules from a collection of I-rules. We show that the general-elimination rules satisfy Pfenning and Davies’ test for local completeness, but question whether that is enough to show that they are stable. Alternative conditions for stability are considered, including equivalence between the introduction- and elimination-meanings of a connective, and recovery of the grounds for assertion, finally generalizing the notion of local completeness to capture Dummett’s notion of stability satisfactorily. We show that the general-elimination rules meet the last of these conditions, and so are indeed not only harmonious but also stable. (shrink)

Ontological pluralism is the view that there are different ways to exist. It is a position with deep roots in the history of philosophy, and in which there has been a recent resurgence of interest. In contemporary presentations, it is stated in terms of fundamental languages: as the view that such languages contain more than one quantifier. For example, one ranging over abstract objects, and another over concrete ones. A natural worry, however, is that the languages proposed by the pluralist (...) are mere notational variants of those proposed by the monist, in which case the debate between the two positions would not seem to be substantive. Jason Turner has given an ingenious response to this worry, in terms of a principle that he calls ‘logical realism’. This paper offers a counter-response on behalf of the ‘notationalist’. I argue that, properly applied, the principle of logical realism is no threat to the claim that the languages in question are notational variants. Indeed, there seems to be every reason to think that they are. (shrink)

Are there different sizes of infinity? That is, are there infinite sets of different sizes? This is one of the most natural questions that one can ask about the infinite. But it is of course generally taken to be settled by mathematical results, such as Cantor’s theorem, to the effect that there are infinite sets without bijections between them. These results settle the question, given an almost universally accepted principle relating size to the existence of functions. The principle is: for (...) any sets A and B, if A is the same size as B, then there is a bijection from A to B. The aim of the paper, however, is to argue that this question is in fact wide open: to argue that we are not in a position to know the answer, because we are not in one to know the principle. The aim, that is, is to argue that for all we know there is only one size of infinity. (shrink)

In a series of papers, 137–158; 1994, Midwest Studies in Philosophy, 23, 61–74, 1999) Fine develops his hylomorphic theory of embodiments. In this article, we supply a formal semantics for this theory that is adequate to the principles laid down for it in. In Section 1, we lay out the theory of embodiments as Fine presents it. In Section 2, we argue on Cantorian grounds that the theory needs to be stabilized, and sketch some ways forward, discussing various choice points (...) in modeling the view. In Section 3, we develop a formal semantics for the theory of embodiments by constructing embodiments in stages and restricting the domain of the second-order quantifiers. In Section 4 we give a few illustrative examples to show how the models deliver Finean hylomorphic consequences. In Section 5, we prove that Fine’s principles are sound with respect to this semantics. In Section 6 we present some inexpressibility results concerning Fine’s various notions of parthood and show that in our formal semantics these notions are all expressible using a single mereological primitive. In Section 7, we prove several mereological results stemming from the model theory, showing that the mereology is surprisingly robust. In Section 8, we draw some philosophical lessons from the formal semantics, and in particular respond to Koslicki’s main objection to Fine’s theory. In the appendix we present proofs of the inexpressibility results of Section 6. (shrink)

Pubblicata per la prima volta nel 1916 come raccolta delle lezioni universitarie dell'anno accademico 1915-16, la "Teoria generale dello spirito come atto puro" andò incontro a diverse ristampe e traduzioni in lingue straniere, diventando uno dei saggi più importanti nella produzione filosofica di Giovanni Gentile. Partendo dal pensiero di Berkeley, Kant e Hegel, il filosofo elabora quello che chiama "idealismo attuale", spesso abbreviato in "attualismo", corrente che ha conosciuto grande fortuna nel periodo tra le due guerre.

The notion of a proposition is central to philosophy. But it is subject to paradoxes. A natural response is a hierarchical account and, ever since Russell proposed his theory of types in 1908, this has been the strategy of choice. But in this paper I raise a problem for such accounts. While this does not seem to have been recognized before, it would seem to render existing such accounts inadequate. The main purpose of the paper, however, is to provide a (...) new hierarchical account that solves the problem. (shrink)

Serious actualism is the prima facie plausible thesis that things couldn’t have been related while being nothing. The thesis plays an important role in a number of arguments in metaphysics, e.g., in Plantinga’s argument for the claim that propositions do not ontologically depend on the things that they are about and in Williamson’s argument for the claim that he, Williamson, is necessarily something. Salmon has put forward that which is, arguably, the most pressing challenge to serious actualists. Salmon’s objection is (...) based on a scenario intended to elicit the judgment that merely possible entities may nonetheless be actually referred to, and so may actually have properties. It is shown that predicativism, the thesis that names are true of their bearers, provides the resources for replying to Salmon’s objection. In addition, an argument for serious actualism based on Stephanou, 219–250 2007) is offered. Finally, it is shown that once serious actualism is conjoined with some minimal assumptions, it implies property necessitism, the thesis that necessarily all properties are necessarily something, as well as a strong comprehension principle for higher-order modal logic according to which for every condition there necessarily is the property of being a thing satisfying that condition.
