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)

Célèbre traducteur et commentateur de Hegel, historien de la philosophie contemporaine, passeur de textes et de concepts, professeur et directeur de travaux universitaires, Jean Hyppolite (1906 - 1968) fut un vrai " protecteur de la nouveauté " et, partant, une figure essentielle au développement de la philosophie française du XXe siècle. Ce livre rassemble, avec les contributions de certains de ses anciens élèves les plus éminents (Badiou, Balibar, Macherey) et de chercheurs étrangers, nombre de ses écrits - dont son premier (...) et son dernier essai - restés inédits ou devenus indisponibles. Un entretien de 1965 entre Jean Hyppolite et Alain Badiou complète le livre. (shrink)

This paper supports the thesis that nihilistic interpretations of Madhyamaka philosophy derive from generally antirealistic and/or metaphysical approaches to Nāgārjuna’s thought. However, the arguments and many images by way of which the author of the Mūlamadhyamakakārikā and his Indian commentators defend themselves from the charge of nihilism show limits in these approaches, and rather confirm that Nāgārjuna’s philosophy should be read as a theoretical proposal that is at once realistic and antimetaphysical. The epistemology inherent to the soteriological dimension of the (...) Buddha’s teaching, of which Nāgārjuna presents himself as a faithful continuer, assesses on the one hand the accomplishment of a ‘cognitive revolution’ consisting in the achievement of a new vision of reality and on the other the avoidance of any metaphysical description of the same vision. Comprehension of the Madhyamaka philosophical enterprise through a realistic-antimetaphysical lens seems to hinder and prevent the possibility of any nihilistic interpretation of Nāgārjuna. (shrink)

Unlike the standard Quantum Computational Logic, where the carrier of information is conventionally assumed to be only the last qubit over a sequence of many qubits, here we propose an extended version of the QCL where the number and the position of the target qubits are arbitrary.

Serial homology, i.e., homology between repetitive structures in the same individual organism, is a debated concept in evolutionary developmental biology. The central question is the evolutionary interpretation of “sameness” in the context of the same body. This essay provides a synthetic analysis of the main issues involved in the debate, connecting conceptual problems with current experimental research. It is argued that a concept of serial homology that is not of the all-or-nothing kind can smooth several theoretical inconsistencies, while being more (...) in line with what we know about evolutionary change and the way we investigate it.

Some time ago I advanced on the pages of this journal a critique of the interpretation given by Jay L. Garfield and Mark Siderits (hereafter GS) of Nāgārjuna’s doctrine of the two truths (Ferraro, J Indian Philos 41(2):195–219, 2013.1); to my article the two authors responded with a ‘defense of the semantic interpretation’ of the Madhyamaka doctrine of emptiness (GS, J Indian Philos 41(6):655–664, 2013). Their reply, however, could not consider my personal understanding of Nāgārjuna’s notions of śūnyatā and dve (...) satye. My interpretation of these notions was in fact absent in the paper GS responded, and was only related in a second paper of mine (Ferraro, J Indian Philos 41(5):563–590, 2013.2), still unpublished at the time of GS’s drafting of their ‘defense’. Therefore, in the present rejoinder, I found it appropriate, rather than responding point by point to the passages of GS’s reply, to advance a comparison between the semantic interpretation and my ‘realist antimetaphysical’ understanding of Nāgārjuna’s thought.

A great deal of "epistemological" thought is dedicated to the question of the origin of the ideas that form our ordinary conception of reality.1 How do we obtain our view of the world as a whole composed of discrete substances, endowed with space-time extension, which are the substrata of specific qualities, linked to each other by different kinds of relation?This is a question that is certainly less problematic in contexts of thought that defend "pluralist" ontologies—where being is thought to amount (...) to a plurality of discrete and self-subsistent entities. There... (shrink)

We informally discuss some recent results on the incompleteness of formal systems. These theorems, which are of great importance to contemporary mathematical epistemology, are proved using a variety of conceptual tools provably stronger than those of finitary axiomatisations. Those tools require no mathematical ontology, but rather constitute particularly concrete human constructions and acts of comprehending infinity and space rooted in different forms of knowledge. We shall also discuss, albeit very briefly, the mathematical intelligence both of God and of computers. We (...) hope in this manner to help the reader overcome formalist reductionism, while avoiding naive Platonist ontologies, typical symptoms of Godelitis which affected many in the last seventy years.

In this book they describe the density wave theory with the goal of making the key concepts and astrophysical implications explicit and accessible.

This work suggests how much human sciences can learn from a booklet almost all cultures know, The Little Prince. It stimulates to read them in their anthropological aspects of behavior facing alterity, highlighting its value without proposing it as educational element to homogenize the different. The reflection is thus focused on the demolishing and lasting effects of European culture during its colonization of American and African people. The contribution ends with Ferraioli and De Vitoria's considerations on a society based on (...) the axiom of the free circulation of men and goods, and the legitimization of thinking given by natural law.

Mainstream theories of decision making conceptualise uncertainty in terms of a well-defined probability distribution or weighting function. Following Knight, radical Keynesians consider subjective expected utility (SEU) theory and its variants as a restricted theory of decision-making applicable to situations of risk and, hence, of limited relevance to the understanding of crucial economic decisions under conditions of fundamental uncertainty in which probabilities are ill-defined, possibly non-existent. The objective of this paper is to outline a radical Keynesian theory of decision-making under uncertainty, (...) arguing that Keynes's suggestion to a two-dimensional probability-credence framework provides the basis for determining the limitations of mainstream approaches and points the way forward to the construction of a more general encompassing theory relevant to psychologists and economists outside of the Keynesian tradition.

In lieu of an abstract, here is a brief excerpt of the content:Figures of Antichrist:The Apocalypse and Its Restraints in Contemporary Political ThoughtGiuseppe Fornari (bio)1. The Antichrist and the Katéchon in Early ChristianityThe history of the Antichrist follows the history of Christ like a shadow.1 This statement is far from banal, not only because of its consequences but also because Christianity as currently presented typically denies that a figure like the Antichrist could be a cause for concern. When confronted with (...) the Antichrist, with Satan in person, the current reaction of many Christians is one of "dialogue." That this may be interpreted, in terms of the doctrine of the Antichrist, as a sign of his proximity passes unnoticed among Christians of goodwill in this day and age. But the devil is never so near as when he is denied or when, following the dictates of what is "politically correct," we start negotiating with him under names that change to suit the occasion. It is a different matter with regard to the historical phenomena that are only indirectly related to Satan, phenomena that help to hold him as far off as possible, but this eventuality can be appreciated only by those who know the devil, not by those who deny him.Some initial comments of a semantic nature are indispensable and, in virtue of the very pregnancy of the term "antichrist," they lead straight to [End Page 53] theological considerations. Antichrist is a synonym of Satan, with the difference that the functional noun "anti-christ" contains a direct indication of the relationship of Satan to Christ; it is the inevitable consequence of the conflict between Satan and Christ. That consequence can only be negation or opposition. The devil, as soon as he encounters Christ, automatically becomes "anti-," which does not imply a personal antipathy—the devil is not a person so much as the principle that parasitically destroys the person—but expresses the consequence of the demystification brought about by Christ: his mask once removed, the devil reveals his true face as Adversary, as "anti-," and the first figure against whom he directs this being "anti-" is necessarily the one who has unmasked him, that is, the Christ. The Greek prefix "anti-" in itself indicated the desire to take someone's place and, consequently, to go against that person; and it is this latter meaning that prevails in the modern prefix. Satan's intention becomes clear when we perceive the perfect convergence between the two nuances of meaning: taking Christ's place in order to go against him and going against Christ in order to take his place. Initially Satan tries out on Christ his old ploy of temptation, and this marks the start of the Son of God's public mission. The conflict is first and foremost a conflict between two functions, between two opposing logics. If Christ were to yield, he would at once fail in his mission from the Father, becoming the antichrist of himself, canceling out his own function and making the very notion of antichrist pointless. Christ does not yield, but this does not mean that his victory has been secured once and for all. He has confirmed his mission, but once this has got under way, all are called to enter into his figure, into his saving function, to become "Christ," which implies that the devil will repeat his temptation with everyone called by Christ. And as Christ is present this time, yielding to temptation marks out the person who yields as antichrist; and, since it is hard to resist temptation, there will be a growing number, not to say a multitude, of antichrists. From the start the word is revealingly characterized, structurally, by its plural form. While we do not have numerous "christs," because to follow Christ means to be as he is and to enter in to be part of him, by which act all the faithful become part of the body of Christ, which is the Church, anyone who becomes the "anti-" of Christ introduces the germ of plurality and discord, because from that moment on he is the "anti-" of the others. The antichrist introduces the poison of the "anti-" into the world, not that it was... (shrink)

Die vorliegende Hommage-Schrift hat das Ziel, Hans Albert – einen der bedeutendsten Wissenschaftsphilosophen und der Hauptvertreter des Kritischen Rationalismus im deutschen Sprachraum – durch biographisch-intellektuelle Zeugnisse zu ehren und die Bedeutung seines Denkens würdigend hervorzuheben. Der Band enthält Beiträge von Kollegen, Schülern und Freunden Hans Alberts in deutscher und englischer Sprache, in denen diese in unterschiedlicher Weise über ihre Beziehung zu Hans Albert berichten und beschreiben, inwiefern dessen Version des Kritischen Rationalismus sie beeinflusst hat. Auf diese Weise wird seine Denkrichtung (...) aus der Perspektive verschiedener Fachdisziplinen wie etwa Wissenschaftstheorie, Ökonomie, Jurisprudenz, Soziologie, Psychologie, Ethik und Theologie betrachtet. Die verschiedenen Beiträge beleuchten nicht nur historische Hintergründe und verschiedene Lebensphasen des Geehrten; sie zeichnen auch die Entwicklung seines Denkens nach und machen seine lebhafte Beteiligung an philosophischen und wissenschaftlichen Auseinandersetzungen seiner Zeit nachvollziehbar. Deshalb kann man diese Hommage-Schrift auch als ein Zeitdokument verstehen, in dem nicht nur Hans Alberts intellektuelles Wirken in Erinnerung gerufen, sondern auch sein Leben vergegenwärtigt wird, von seiner Zeit als wissenschaftlicher Assistent bzw. Privatdozent in Köln bis zu seiner Emeritierung in Mannheim und darüber hinaus. (shrink)
