This book provides a general survey of the main concepts, questions and results that have been developed in the recent interactions between quantum information, quantum computation and logic. Divided into 10 chapters, the books starts with an introduction of the main concepts of the quantum-theoretic formalism used in quantum information. It then gives a synthetic presentation of the main “mathematical characters” of the quantum computational game: qubits, quregisters, mixtures of quregisters, quantum logical gates. Next, the book investigates the puzzling entanglement-phenomena (...) and logically analyses the Einstein–Podolsky–Rosen paradox and introduces the reader to quantum computational logics, and new forms of quantum logic. The middle chapters investigate the possibility of a quantum computational semantics for a language that can express sentences like “Alice knows that everybody knows that she is pretty”, explore the mathematical concept of quantum Turing machine, and illustrate some characteristic examples that arise in the framework of musical languages. The book concludes with an analysis of recent discussions, and contains a Mathematical Appendix which is a survey of the definitions of all main mathematical concepts used in the book. (shrink)

Contrary to the fairly standard view of Aquinas on temperance according to which this virtue habituates the concupiscible appetite to move in ways that accord with reason spontaneously, that is, independently of any immediate command from reason, the author of this paper argues that temperance is a virtue which "(1) disposes the concupiscible appetite to remain more or less still in the absence of any command from reason to move, thus preventing vehement, spontaneous passions of any sort, ordinate or inordinate, (...) from arising in the concupiscible appetite prior to reason's immediate command; and (2) also disposes the concupiscible appetite to obey reason's command so that a person may incite, increase, decrease, or curb a passion as needed." The paper ends by noting a lacuna in Aquinas's teaching on temperance. (shrink)

Este estudio analiza el problema de la relación entre metafísica e historia en la filosofía viquiana, y cómo ésta es capaz de reconducir el certum al verum. Plantea el autor cómo Vico mantiene unidos los modelos racionales, posibilitando un universalismo ético que permite conjugar la normatividad del juicio universal y la diferencia histórico-cultural de lo individual.PALABRAS CLAVE: Vico, ética, universalismo ético, identidad, diferencia, historicidad.The problematic relationship between metaphysics and history in Vichian philosophy is here analysed –and the way it transforms (...) certum into verum. The author considers Vico’s attempts to keep rational models together, allowing the appearance of an ethical universalism that combines universal judgment normativity and historical-cultural difference of the individual.Keywords: Vico, ethics, ethical universalism, identity, difference, historicity.

This dissertation examines Aquinas's teaching on the acts specific to temperance. According to a widespread interpretation of this teaching , the proper act of temperance is spontaneous, ordinate passion. Temperance thus not only causes someone to experience the right passions towards the right objects but does so antecedent to reason's command. Indeed, temperance is thought to have little if anything to do with reason's control of the passions. In an introductory chapter, I show that this understanding of temperance faces a (...) number of serious objections. In the next four chapters, I develop the thesis that the proper act of temperance is ordinate, consequent passion alone; the only relation temperance has to antecedent passion is simply to prevent it from ever being vehement, affecting only its intensity, not its ordination. ;I develop my thesis by examining Aquinas's teaching on the passions, which can only be consistently ordinate if commanded by reason ; reason's control of the passions, which can be consistent only if the sense appetite is habituated to obey reason alone, thus preventing it from being moved by any of the external or internal sense powers when they move antecedent to reason's command ; habit, which is not a principle of spontaneous action or passion, but is rather something we use only when we will . Temperance is thus a habit that gives reason nearly complete control of the passions, a moral virtue that is used only when we will and thus is exclusively a cause of ordinate, consequent passion . ;In the final chapter, observing that Aquinas is silent on the consistency with which the temperate person experiences spontaneous, ordinate passions, I attempt to fill this lacuna by developing the notions of "semi-virtue" and "semi-virtuous passion," building on Aquinas's teaching on the internal sense powers, especially the cogitative power.

This paper analyzes Zubirian concept of historical reality and it is focused on “traditive transmission” and on History refluence on human reality. It also hints at a comparison between Zubiri and Dilthey on the concept of life and it tries to show a proximity started from the role played by the concept of unreal and figuration. At the end, it deals with the figure of Ellacuria and the way in which he has developed Zubirian reflection on History in the terms (...) of Philosophy of liberation. The ethical dimension of Zubiri’s philosophy is one of the characteristics of a Metaphysics compatible with pluralism and for this reason worthy of the times. (shrink)

Automation and information technology have transformed the organization of labor to such an extent that the processes of exploitation have moved beyond the labor class and now work upon society as a whole. If this displacement has destroyed the political primacy of the labor class, it has not, however, eliminated exploitation; rather, it has broadened it, implanting it within the given conditions of the most diverse spheres of society. -- from The Winter Is Over In late 1995, in opposition to (...) the conservative agenda of Jacques Chirac and his prime minister Alain Juppé and their proposed widespread welfare cuts, French students rose up against their government; public sector workers, together with all the major trade unions, went on strike. When railway workers and Paris Metro personnel joined in the protests, France's public transportation system came to a halt. These extensive social upheavals, the likes of which had not been seen in France since 1968, found widespread public support and fuelled the creation of many political organizations. Chirac backed down from restructuring the public retirement system. Antonio Negri's _T_he Winter is Over comes out of the glimmer of optimism created by the events of 1995, when the long, cold season of neoliberalism, Thatcherism, Reaganomics, reaction, and counterrevolution appeared to have run its course. Published in Italian in 1996, _The Winter is Over_ brings together a series of articles, speeches, and other documents written by Negri between 1989 and 1995 at the threshold of this thaw. It offers a revealing and wide-reaching account of those years of change and brink-of-change, focusing on such topics as the networks of social production, the decline of "limp thought," the end of applied socialism, the Gulf War, and, finally, Italy's transition to its so-called "Second Republic," as seen by an exile.

In this paper Giuseppe Bianco analyzes the ideological and epistemological coordinates and the space of possibilities proper to the cluster of philosophy students of which Tournier was part between 1943 and 1948; to do so he reconstructs their evolution in a context dominated by the currents of Neo-Scholasticism, Personalism, phenomenology, Marxism, and Existentialism. Finally, he focuses on the importance of Jean-Paul Sartre for these young people, underlining their particular interpretation of his work.
