In recent works, Časlav Brukner and Jacques Pienaar have raised interesting objections to the relational interpretation of quantum mechanics. We answer these objections in detail and show that, far from questioning the viability of the interpretation, they sharpen and clarify it.

Facts happen at every interaction, but they are not absolute: they are relative to the systems involved in the interaction. Stable facts are those whose relativity can effectively be ignored. In this work, we describe how stable facts emerge in a world of relative facts and discuss their respective roles in connecting quantum theory and the world. The distinction between relative and stable facts resolves the difficulties pointed out by the no-go theorem of Frauchiger and Renner, and is consistent with (...) the experimental violation of the Local Friendliness inequalities of Bong et al.. Basing the ontology of the theory on relative facts clarifies the role of decoherence in bringing about the classical world and solves the apparent incompatibility between the ‘linear evolution’ and ‘projection’ postulates.

Lawrence et al. have presented an argument purporting to show that “relative facts do not exist” and, consequently, “Relational Quantum Mechanics is incompatible with quantum mechanics”. The argument is based on a GHZ-like contradiction between constraints satisfied by measurement outcomes in an extended Wigner’s friend scenario. Here we present a strengthened version of the argument, and show why, contrary to the claim by Lawrence et al., these arguments do not contradict the consistency of a theory of relative facts. Rather, considering (...) this argument helps clarify how one should not think about a theory of relative facts, like RQM. (shrink)

Journal Name: Philologus Issue: Ahead of print.

The author returns to a much debated topic, the so-called “Episode of Helen”, which has come to us only through indirect transmission, and endeavors to dismantle the prejudice against Virgilian authorship. G. P. Goold’s pugnacious intervention, dating back to more than half a century ago, contributed decisively – in fact, more than it should have – to the thesis that the text is spurious. A critical analysis of the text will demonstrate this claim to be groundless while offering arguments that (...) support the authenticity of the episode. (shrink)

Nell'agosto del 1462 papa Pio II investiva il cardinale Bessarione di Nicea della commenda del monastero di Grottaferrata, che succedeva al calabrese Pietro Vitali, ultimo degli egumeni de regimine, eletto a capo dell'Archimandritato di Messina. Uno dei primi atti di governo di Bessarione fu di incaricare l'arcivescovo di Siponto Niccolò Perotti, quale suo procuratore, di procedere ad una dettagliata ricognizione dei beni mobili e immobili del monastero criptense. I relativi inventari ci sono pervenuti nei mss. Grottaferrata Z. δ. XII (ff. (...) 1-63) per i beni immobili, e Grottaferrata, Archivio del Monumento Nazionale, 523 (ff. 105-116) per i beni mobili. Nei ff. 108v-110 di quest'ultimo documento, la cui redazione era stata affidata dal Perotti al notaio Stefano Tegliati (o Tegliazio), si trova il primo sommario elenco conosciuto dei libri manoscritti della biblioteca, pubblicato da Pierre Batiffol e poi da Antonio Rocchi. Vi risultano 114 manoscritti greci, 2 latini e «circa viginti volumina librorum sine principio et mala ordinata». (shrink)

Biagio Tassone's study From Psychology to Phenomenology offers an in depth exploration of Brentano's seminal work as an example of a still relevant approach to philosophy of mind.

On man, from the religious to the scientific aspects, and the salient characteristics which distinguish him from other animals, with a description of the passage which has consolidated the author's own religious faith.

This paper critically examines the philosophical foundations of Colin Wilson’s New Existentialism. I will show how Wilson’s writings promoted a phenomenological strategy for understanding states of ecstatic affirmation within so-called ‘peak experiences’. Wilson subsequently attempted to use the life affirming insights bestowed by peak states to establish an ontological ground for values to serve as a foundation for his New Existentialism. Because of its psychological focus however, I argue that Wilson’s New Existentialism contains an ambivalent framework for establishing ontological categories, (...) which leads his thought into theoretical difficulties. More precisely, Wilson’s strategy runs into problems in coherently integrating its explicitly psychological interpretation of Husserl’s theory of intentionality within a broader, and philosophically coherent, phenomenological framework. Wilson’s psychological reading of Husserl’s transcendental reduction, for example, manifests tensions in how it reconciles the empirical basis of acts of transcendence with an essentialist conception of the self as a transcendental ego. The above tensions, I argue, ultimately render the New Existentialism susceptible to criticism from a Husserlian-transcendental perspective. After outlining a Husserlian critique of Wilson’s position, I end the paper by suggesting how some of the central insights of the New Existentialism might help to bridge the gap that persists between pure phenomenological description and metaphysics.

Cornelius Nepos tells us that when Cato talked of wars, he did not mention the generals’ names, but stuck to events without ever glorifying the protagonists. He saw the military exploits themselves as important and not the pride they might inspire in noblemen who were often more concerned with their personal merit than the glory of the Roman people. However, he made a few exceptions to this rule, which, precisely because they were rare, made the individual selected appear more brilliant. (...) I shall do likewise. I intend to present a survey that will give a full account of the body of knowledge that has been consolidated between the end of the war and today. I shall deliberately give more emphasis to general trends than to specific results, highlighting the overall picture rather than individuals as such. But, as I have indicated, I shall break my rule occasionally to point to the birth of a new idea or to show how cooperative work developed out of an individual's vision. (shrink)

"Ces "questiones" sont particulièrement reprèsentatives de la logique italienne au XIVe siècle.

In the Aeneid, Virgil sets out to achieve a new sublime style, paradoxically steeped in the common parlance. He aims for the spontaneity of everyday language to win readers’ involvement, while elaborating a discourse both expressively taut and stylistically marked, that avoids a register too colloquial or prosaic. Above all, he tirelessly deploys an array of subtle strategies – below the threshold of perception – that defamiliarize language in order to elevate its style. The present paper furnishes a selection of (...) case studies. (shrink)
