La tradizione cristiana e il ";trascendentalismo della prassi"; nella riflessione di Dal Pra. La presenza di Vasa e l'assenza di Martinetti.

The reception of the work of Thucydides in late antique authors constitutes a huge chapter of allusions and reworkings, on methodological, structural, lexical levels and more. A fortiori, certain particularly famous passages by the historian are well suited for a study of their reception, above all where key terms or rare expressions are concentrated. The case of the adjective ἀλγεινός, a poeticism declined twice in the epitaphios of Pericles (2.39 and 2.43) offers interesting material of this kind in the work (...) of Dexippus, the Athenian historian of the third century A.D., and in the romance author Heliodorus. Alongside a secure reference to 2.39 in Dexippus (F28 Martin = F34 Mecella), already identified by Stein, it is possible to identify a further reuse in another fragment, probably extracted from a demegoria (F26b Martin = F32b Mecella). In the light of these examples, it becomes more likely that we can see a reminiscence of Thucydides also in a passage of Heliodorus of Emesa (5.29), already proposed by van Krevelen but omitted from the repertory of citations present in the Aethiopica prepared by Feuillâtre.

The present contribution is the first half of a two-part study. It deals with a group of so-called «presbyters» (presbyteroi) to whom Irenaeus of Lyons refers as sources in his exstant works. He introduces them as pupils of John, «the disciple of the Lord», whose teaching they were deemed to transmit orally. This is an ideal image of a generation of believers in Jesus intermediate between Jesus’s direct disciples and the believers of further generations who would have no personal connection (...) to Jesus nor to those who had been with him. For one specific saying, Irenaeus mentions as his sources the presbyters as well as Papias of Hierapolis, who had written a work including sayings of Jesus with their interpretation. Papias also claimed that he had received such sayings through «the presbyters», so we have to determine whether Irenaeus knew the presbyter’s traditions only through Papias’s work or also independently from it. Finally, the article compares Irenaeus’s appeal to the presbyters with some passages where Clement of Alexandria referred to presbyters’ teachings in a similar way ten to twenty years after Irenaeus in a different milieu. The second part of this study will examine how Irenaeus used the notion of presbyters in order to support the process that led to establishing a «monepiscopate» in the Roman Church. (shrink)

The encounter of different cultures characterizes liberal-democratic societies in the era of economic and technological lobalization. The interference of new technologies and the relationship between them and the diverse cultures could give rise contrasting ways of giving and doing justice. The fundamental thesis, which I intend to put forward, is that the relation between culture and justice within the «Global Technological Society» is quite profound and requires the adoption of contemporary forms of normativity, both thin and thick,in such way as (...) to allow the recognition of those cultural and intercultural elements, which are present in the concept of justice.

In this paper I set out to read Hägerström through his own eyes, adhering to the terminology he uses in his own original work and attempting to make sense of the variance and uniformity alike that one finds in his linguistic usage. The translations we have of Hägerström's works are quite liberal, using the same word in English where the original uses different ones, and, vice versa, using different words in English where the original uses a single one in different (...) contexts. These misleading translations of Hägerström have contributed in some measure to Hägerström's reputation for obscurity. Further, and most importantly, I will take seriously what Hägerström says about his own thought, namely, that it is dependent on that of Kant and independent of the currents of thought contemporary with Hägerström. In Section 1, I will briefly take up the problem of consciousness that Hägerström proceeds from, and will recall something that Bertrand Russell once said, in 1928, in regard to the revolt staged in the early 20th century in Europe against German idealism. In Sections 2 and 4.1, I will instead take up Kant for the purpose of clarifying Hägerström's theory of judgment as treated in Section 3. In Section 4.2, I will illustrate the difference between the notions of nothing, R-reality, and W-reality in Hägerström. In Sections 5 and 6, I will examine the analysis that Hägerström offers of the principle of contradiction, and will summarize the three types of judgment he singled out, including the type he called impossible judgment. In Section 7, I will consider Hägerström views as grounding, in a transcendental way, the presupposition of the primacy of the external spatio-temporal world, a world independent of our representations: I will consider in particular the W-real complexes that are merely represented, as well as the spatio-temporal world as the only W-real complex that is not merely represented. Finally, in Section 8, I will briefly consider some of those who have commented and translated Hägerström, this to conclude that R-reality and W-reality are coextensive but not synonymous. (shrink)

The traditional standard quantum mechanics theory is unable to solve the spin–statistics problem, i.e. to justify the utterly important “Pauli Exclusion Principle”. A complete and straightforward solution of the spin–statistics problem is presented on the basis of the “conformal quantum geometrodynamics” theory. This theory provides a Weyl-gauge invariant formulation of the standard quantum mechanics and reproduces successfully all relevant quantum processes including the formulation of Dirac’s or Schrödinger’s equation, of Heisenberg’s uncertainty relations and of the nonlocal EPR correlations. When the (...) conformal quantum geometrodynamics is applied to a system made of many identical particles with spin, an additional constant property of all elementary particles enters naturally into play: the “intrinsic helicity”. This property, not considered in the Standard Quantum Mechanics, determines the correct spin–statistics connection observed in Nature. (shrink)

The Aristotelian tradition in a sense is constituted by the history of Aristotelianism, i. e. by the philosophies of those who declared themselves Aristotle’s followers, even if in fact they hardly ever have been completely such. But in another sense the Aristotelian tradition is formed by the patrimony of concepts, distinctions, definitions, of which not only the philosophy, but also the culture in general, and even the common language, made use for millennia and of which still now they make use: (...) category, subject-predicate, square of oppositions, syllogism, induction, refutation, contradiction, matter-form, potency-act, essence, substance-accident, types of cause, types of change, nature-art, time, place, infinite, chance, luck, soul-body, sensation, memory, fantasy, experience, intellect, desire, analogy, mean-end, action- production, choice, deliberation, virtue, happiness, justice, friendship, city, family, slavery, constitution, revolution, persuasion, character, passion, poetry, tragedy, myth, catharsis, etc. (shrink)

The problem of the interpretation of the Timaeus represents one of the greatest exegetical challenges for Plotinus. For Plotinus the Timaeus is a problematic dialogue due to its mythical-allegorical language and the fact that some doctrines in the work seem incompatible with his hypostatic vision. The Plotinian conception of the demiurge is critical of the concept of “artisanal causality.” Plotinus does not agree that the cosmos could have been generated according to a plan, i.e., according to dianoetic and contingent reasoning. (...) At the same time, he identifies the demiurge with the Intellect, but then, in other treatises, also equates the demiurge with the world soul and nature, i.e., the aspect of the third hypostasis that has the task of acting directly on matter. While this ambiguity of Plotinus is found in several places of his Enneads, it finds justification in a spurious dialogue of Plato, the Epinomis, in which the role of the demiurgic soul is central. In my opinion, Plotinus is likely to have taken his cue from the Epinomis as an endorsement for his doctrine of the demiurgic soul. Nevertheless, the fact remains that the identification of the demiurgic soul with a single hypostasis leads Plotinus to several aporias. (shrink)

Regardless of whether one agrees or disagrees with Stacie Friend’s claim that fiction is a genre, her notion of genre can be fruitfully applied to a paradigmatic genre such as science fiction. This article deploys Friend’s notion of genre in order to improve the influential characterization of science fiction proposed by Darko Suvin and to defend it from a criticism recently raised by Simon Evnine. According to Suvin, a work of science fiction must concern “a fictional ‘novum’ validated by cognitive (...) logic.” While Suvin conceives of his characterization as a necessary and sufficient condition for membership in the genre, I propose to cast the notions of “fictional novum” and “cognitive validation” as standard features of the genre, which works of science fiction should have but might lack. I argue that this amended version of Suvin’s characterization can better account for two basic properties of science fiction as a genre, namely its historicity and its relevance to appreciation. Lastly, I show that the amended version can shed some light on the affinity between works of science fiction and philosophical thought experiments. (shrink)

Works of art are usually meant to elicit psychological effects from their audiences whereas paradigmatic technical artifacts such as hammers or cars are rather meant to produce physical effects when used. This suggests that works of art and technical artifacts are sharply different entities. However, recent developments in the cognitive sciences and the philosophy of technology have individuated special artifacts, namely cognitive and affective artifacts, which also generate psychological effects. In particular, affective artifacts, which have the capacity to alter the (...) affective condition of agents, seem to share crucial features with works of art. Can we subsume works of art under that kind? I will argue that we cannot. Still, comparing art with affective artifacts will help us to clarify the relationship between art and technology, and to introduce a new category, namely the experiential artifact, which can properly encompass works of art.

The traditional standard theory of quantum mechanics is unable to solve the spin–statistics problem, i.e. to justify the utterly important “Pauli Exclusion Principle” but by the adoption of the complex standard relativistic quantum field theory. In a recent paper :858–873, 2015) we presented a proof of the spin–statistics problem in the nonrelativistic approximation on the basis of the “Conformal Quantum Geometrodynamics”. In the present paper, by the same theory the proof of the spin–statistics theorem is extended to the relativistic domain (...) in the general scenario of curved spacetime. The relativistic approach allows to formulate a manifestly step-by-step Weyl gauge invariant theory and to emphasize some fundamental aspects of group theory in the demonstration. No relativistic quantum field operators are used and the particle exchange properties are drawn from the conservation of the intrinsic helicity of elementary particles. It is therefore this property, not considered in the standard quantum mechanics, which determines the correct spin–statistics connection observed in Nature :858–873, 2015). The present proof of the spin–statistics theorem is simpler than the one presented in Santamato and De Martini :858–873, 2015), because it is based on symmetry group considerations only, without having recourse to frames attached to the particles. Second quantization and anticommuting operators are not necessary. (shrink)

These are the proceedings of the Workshop on Quantum Logic held in Erice (Sicily), December 2 - 9, 1979, at the Ettore Hajorana Centre for Scientific Culture. A conference of this sort was originally proposed by Giuliano Toraldo di Francia, who suggested the idea to Antonino Zichichi, and thus laid the foundation for the Workshop. To both of them we express our appreciation and thanks, also on behalf of the other participants, for having made this conference possible. There were approximately (...) fifty participants; their names and institutions are listed in the text. Quantum logic, which has now a history of some forty or more years, has seen remarkable growth during the sixties and seventies. The papers in the present volume presuppose, by and large, some acquaintance with the elements of the subject. These may be found in the well-known books by J.H. Jauch (Foundations of Quantum Hechanics; Reading, 1968), V.S. Varadarajan (Geometry of Quantum Theory: Princeton, 1968), and C. Piron (Foundations of Quantum Theory; New York, 1976). The initial program for the conference listed about twenty-five invited papers. But in the context of a very active and qualified attendance, other contributions were offered. This volume contains all of them. The program listed six main topics: I. Classification or different areas of quantum logic, and open problems. II. Comparison and unification of different approaches to quantum theories; problems of interpretation. III. Formal quantum logic; axiomatics. IV. Hodal interpretations of quantum logic. v vi FOREWORD V. Quantum set theory. (shrink)

This paper considers two issues raised by the claim that fictional characters are abstract artifacts. First, given that artifacts normally have functions, what is the function of a fictional character? Second, given that, in experiencing works of fictions, we usually treat fictional characters as concrete individuals, how can such a phenomenology fit with an ontology according to which fictional characters are abstract artifacts? I will indirectly address the second issue by directly addressing the first one. For this purpose, I will (...) rely on the notion of a mental file. I will argue that the function of fictional characters is the generation of mental files of a special kind. I will show that our experience of fictional characters as concrete individuals depends on the kind of mental files that are generated by fictional characters as abstract artifacts. I will conclude that an appreciator of a work of fiction can open two files about a certain fictional character; one about the character as an individual in the fictional world, and the other about the character as an abstract artifact in the actual world. In this sense, our relation to a fictional character is characterized by a duality of files or ‘twofileness’. (shrink)

The paper compares the thought of Democritus and that of Colotes. It is argued that the two thinkers diverge at least in three noteworthy respects: 1) they disagree about the nature of knowledge, for Democritus identifies it with a process which goes from raw (and untrustworthy) sensation to intellectual understanding, whereas Colotes affirms the truth of every sensation and its fundamental role in the use of reason; 2) they have contrary opinions on the practice of “pleasing”, since the former totally (...) rejects this as a damaging form of obsequiousness, while the latter allows a form of pleasing which is good, i.e. which can lead to pleasure and security; 3) they describe death differently, for Democritus affirms that it consists in the loss of most of the soul atoms (which also allows, to a certain degree, the phenomenon of the “return to life”), whereas Colotes may have followed Epicurus in depicting death as the complete loss of soul particles. Such an investigation suggests, on both historical and philosophical grounds, that Democritus and Colotes did not embrace the same kind of atomism, but two atomisms, which start from different premises and pursue different goals.

In this paper I argue that Rawlsians have largely misunderstood the idea of an overlapping consensus of reasonable comprehensive doctrines, thereby failing to delineate in an appropriate way the place of comprehensive doctrines in political liberalism. My argument rests on two core claims. The first claim is that (i) political liberalism is committed to three theses about the overlapping consensus. The first thesis concerns the subject of the overlapping consensus; the second thesis concerns the function of the overlapping consensus; the (...) third thesis explains how the overlapping consensus can serve its function in accordance with political liberalism’s commitment to epistemic neutrality. The second claim on which my argument relies is empirical: (ii) Rawlsians typically deny at least one of the three theses to which political liberalism is committed. Based on (i) and (ii), I conclude that Rawlsians have hitherto provided unconvincing accounts of the place of comprehensive doctrines in political liberalism. (shrink)

This article applies to the social dimension of the Salesian mission. Subject was, chronologically, included in the three points. The article begins with the presentation of the social aspect of the life of the Founder of the Salesians – St. John Bosco. Then it moves to the activity of Bl. Michael Rua and the contribution of other saints, the servants of God and candidates for sainthood from the Salesian Family. The last point indicates a variety of pro-social activities in the (...) above mentioned areas in recent years. This article, of which the author is the Postulator for the Causes of Saints of the Salesian Family, is a contribution to the celebration of 150th anniversary of the Salesian Congregation (1859 – 2009).
