The notion of ‘omnipotence’ (potentia dei) runs through the history of medieval philosophy especially after the contribution of Augustine’s thought. Augustine thus traces ethical developments from the idea of God’s sovereignty to the construction of an order of things comparable with his power of creation. Augustine was the first Christian thinker to introduce and document the notion of potentia dei in an ethical context, proving at the same time that the ambivalence of God’s power results either from the activity of (...) ordering, or from the impossibility of God’s duplication, or from the incapacity to destroy the world in respect to a rational configuration of laws and events.

In a well-known tradition, basically marked by the influence of Augustinian thought, the notion of divine omnipotence fixes the conceptual space of theology in the XI century, especially in accordance with the primacy of logical subjects. Among others, Anselm of Canterbury gives to XII century the opportunity to settle this conceptual reference, disclosing and organizing many argumentative solutions of the late scholastic period.

The emergence of ecology as a fundamental horizon not only of politics, but also of contemporary philosophy, pushes us to rethink the relationship that currents of thought such as Kuturkritik and phenomenology, especially the phenomenology of Maurice Merleau-Ponty, can maintain with it. After a preliminary consideration of post-structuralist and postmodern positions from this perspective, the essay focuses on the French philosopher, and in particular on his courses on Nature and on his elaboration of the Husserlian concept of Stiftung. This results (...) in Merleau-Ponty’s original position on the Kultur – Civilization alternative: critique of unlimited productivism, respect for the environment, and, at the same time, defense of the variety of cultures and traditions from a homogenizing globalization are valuable tools that his philosophy offers to the debates of our time.

Una prima parte del saggio sintetizza le linee principali di un recente libro dell’autore: Per un paradigma del corpo: una rifondazione filosofica dell’ecologia, Quodlibet, Macerata, 2019. Viene sostenuto un paradigma in cui corpo e biologia mantengano la loro irriducibilità nei confronti della cultura e in cui il cosiddetto “linguistic turn”, che ha dominato la filosofia del XX secolo, viene fortemente criticato; in coerenza con questo, la riflessione di Merleau-Ponty sul concetto di natura viene considerata lo strumento più adeguato e (...) più attuale per ripensare la questione ecologica; ne vengono esaminate le conseguenze nel campo della filosofia della tecnologia e del problema del soggetto. Una seconda parte del saggio, che si concentra sull’incontro che ebbe luogo nel 1961 fra Adorno e Merleau-Ponty, cerca di abbozzare un paradigma materialistico per l’ecologia, correggendo l’avvicinamento che alla fine della sua vita vi fu fra Merleau-Ponty e Heidegger.

With regard to the interpretation of the conversation between Jesus and the Samaritan woman examined by Origen in Book 13 of the Commentary on John, in this study the Author analyzes certain terms or expressions on which Origen’s analysis focuses, and he concludes that the great Alexandrian exegete does not seem to show his best skills in these explanations.

Gli studi di Simha Arom sulla polifonia africana ha avuto un notevole impatto sulla cultura occidentale, in modo particolare con riferimento alla teoria ritmica della composizione. Scopo principale di questo studio è discutere la relazione fra la comparsa di termini antichi relativi alla teoria musicale e l’effettiva possibilità di descriverli in contesti musicali moderni.Gli studi di Simha Arom sulla polifonia africana ha avuto un notevole impatto sulla cultura occidentale, in modo particolare con riferimento alla teoria ritmica della composizione. (...) Scopo principale di questo studio è discutere la relazione fra la comparsa di termini antichi relativi alla teoria musicale e l’effettiva possibilità di descriverli in contesti musicali moderni.In che modo si possono usare concetti come talea, color, organum nella descrizione di strutture ritmiche concepite al di fuori della teoria canonica occidentale? Gli scritti di Arom mostrano come oggi sia ancora possibile individuare un nesso tra modelli africani di scansione ritmica e il concetto occidentale di dissonanza temporale: ma qual è il ruolo della percezione all’interno di questa descrizione? Simha Arom’s Studies in African Polyphony had a great impact in Western Culture, especially inside the Rhythmic Theory of Composition: the main aim of this work is a discussion about the relationships between the occurrences of ancient terms connected to music theory and the strength possibility of description in modern music contexts.How can we use concepts like Talea, Color, Organum in the description of rhythmical structures conceived outside the western canonical theory? The Arom’s writings show us that today is still possible to establish a link between African models of Rhythmical periods and the Western Concept of temporal dissonance: but what is the role of perception inside this description?

L’articolo intende proporre una lettura del _Breve trattato sulle cause che possono far abbondare li regni d’oro e d’argento_ di Antonio Serra incentrata su una storia delle arti di governo. Ricostruendo il dibattito napoletano sulle cause della crisi monetaria degli inizi del XVII secolo e focalizzando l’attenzione sul problema delle pratiche di governo della moneta, l’obiettivo del saggio è quello di sottrarre il trattato di Serra all’ipoteca di una retrospettiva sulla scienza economica per inquadrarlo all’interno dei (...) problemi politici del proprio tempo.

Nella storiografia filosofica spagnola non esiste, probabilmente, una definizione ambigua e problematica come quella che riguarda la cosiddetta "Scuola di Barcellona". La tesi principale di questo articolo è che tale scuola non giunse mai a nascere, ma ne esistette soltanto una forma embrionale che non poté maturare perché, in conseguenza della situazione politica venutasi a creare con la guerra civile , i suoi componenti si dispersero nell'esilio. Ciò nonostante, è possibile riconoscere alcuni tratti comuni, seppur labili e non sostanziali, (...) nella diaspora degli intellettuali catalani che rendono possibile definirla, con le dovute cautele, "Scuola di Barcellona". Tali caratteristiche comuni si possono far risalire a colui che, in un certo senso, fu il fondatore della scuola, essendo il principale maestro delle nuove leve filosofiche della Catalogna all'inizio del XX secolo: Jaume Serra Hunter. The expression "Barcelona School" is hard to find in the history of Spanish philosophy. The main thesis of my essay is that the "Barcelona School" never really existed. On the other hand, some kind of embryonic philosophical project was in fact sketched in the 1930s, but it could not attain its peak and full development because many scholars had to go into exile as a consequence of the Spanish Civil War . It is possible, nevertheless, to make a list of strong common points and aims among members of the Catalan intellectual diaspora, which would perhaps allow us to speak of a "Barcelona school". Such common points and aims can be found in the thought of the philosopher Jaume Serra Hunter, the most representative figure among the new philosophers in Catalonia at the beginning of the 20th century.

This thesis is devoted to the exploration of the complexity of some mathematical problems using the framework of computable analysis and descriptive set theory. We will especially focus on Weihrauch reducibility as a means to compare the uniform computational strength of problems. After a short introduction of the relevant background notions, we investigate the uniform computational content of problems arising from theorems that lie at the higher levels of the reverse mathematics hierarchy.We first analyze the strength of the open and (...) clopen Ramsey theorems. Since there is not a canonical way to phrase these theorems as multi-valued functions, we identify eight different multi-valued functions and study their degree from the point of view of Weihrauch, strong Weihrauch, and arithmetic Weihrauch reducibility.We then discuss some new operators on multi-valued functions and study their algebraic properties and the relations with other previously studied operators on problems. In particular, we study the first-order part and the deterministic part of a problem f, capturing the Weihrauch degree of the strongest multi-valued problem that is reducible to f and that, respectively, has codomain $\mathbb {N}$ or is single-valued.These notions proved to be extremely useful when exploring the Weihrauch degree of the problem $\mathsf {DS}$ of computing descending sequences in ill-founded linear orders. They allow us to show that $\mathsf {DS}$, and the Weihrauch equivalent problem $\mathsf {BS}$ of finding bad sequences through non-well quasi-orders, while being very “hard” to solve, are rather weak in terms of uniform computational strength. We then generalize $\mathsf {DS}$ and $\mathsf {BS}$ by considering $\boldsymbol {\Gamma }$ -presented orders, where $\boldsymbol {\Gamma }$ is a Borel pointclass or $\boldsymbol {\Delta }^1_1$, $\boldsymbol {\Sigma }^1_1$, $\boldsymbol {\Pi }^1_1$. We study the obtained $\mathsf {DS}$ -hierarchy and $\mathsf {BS}$ -hierarchy of problems in comparison with the Baire hierarchy and show that they do not collapse at any finite level.Finally, we work in the context of geometric measure theory and we focus on the characterization, from the point of view of descriptive set theory, of some conditions involving the notions of Hausdorff/Fourier dimension and Salem sets. We first work in the hyperspace $\mathbf {K}$ of compact subsets of $[0,1]$ and show that the closed Salem sets form a $\boldsymbol {\Pi }^0_3$ -complete family. This is done by characterizing the complexity of the family of sets having sufficiently large Hausdorff or Fourier dimension. We also show that the complexity does not change if we increase the dimension of the ambient space and work in $\mathbf {K}$. We also generalize the results by relaxing the compactness of the ambient space and show that the closed Salem sets are still $\boldsymbol {\Pi }^0_3$ -complete when we endow $\mathbf {F}$ with the Fell topology. A similar result holds also for the Vietoris topology.We conclude by analyzing the same notions from the point of view of effective descriptive set theory and Type-2 Theory of Effectivity, and show that the complexities remain the same also in the lightface case. In particular, we show that the family of all the closed Salem sets is $\Pi ^0_3$ -complete. We furthermore characterize the Weihrauch degree of the functions computing Hausdorff and Fourier dimension of closed sets.prepared by Manlio Valenti.E-mail:[email protected]. (shrink)
