Premessa: Leibniz e l'«arte di comporre dialoghi»
No full textThis preface introduces 16 dialogues or fragments of dialogue composed by Leibniz, edited and translated in 2007 by several scholars under Francesco Piro's direction. In his Preface, Piro explains the reasons of Leibniz's involvement with the "art of composing dialogues", connecting this involvement with Leibniz's epistemological "perspectivism" and with his virtualist interpretation of the Doctrine of Innate Ideas. Moreover, the preface discusses Leibniz's first attempts of Theodicy, his way to monadology, and other sides of Leibniz's philosophy which can be more clearly understood through his dialogues. Piro's Preface is followed by an Introduction to each dialogue composed by the editors/translaters of the single works: the Introduction to the dialogues 1-2-3-4-5-6-7-8-9 and 14-15 are even by Piro
2D and 3D data processing of archaeo-magnetic data
No full textIntroduction. The Sabine Necropolis at Colle del Forno (700-300 B.C.) at Montelibretti, Rome is characterized by dromos chamber tombs, most of them unexplored till now. The tombs can be assimilated to cavities of a standard volume of some cubic meters; the entrance of the tombs is a corridor 6 m long with a 1 square meter section . The surficial geology of the area consists of a series of tuffs about 10 m thick overlying Pleistocene-Quaternary sandy-clayey sediments. A thin layer of top soil (20 - 30 cm) covers the tuff. The investigation of the Necropolis in the past decade has been performed by different geophysical methodologies: electrical, electromagnetic and magnetic methods have been widely adopted to investigate several chamber tombs (Piro et al, 2001). The aim of this paper is to analyze an integrated approach to the processing of magnetic survey data. The magnetic susceptibility contrast between topsoil, subsoil and rocks (topsoil is normally more magnetic than subsoil) permits to detect ditches, pits and other silted-up features that were excavated and then silted or back-filled with topsoil. Meanwhile back-filled areas produce positive anomalies, less magnetic material introduced into topsoil, including many kinds of masonry (for example, limestone walls) may produce negative anomalies of the order of some nanoteslas. The same behavior is related to the presence of cultural voids and tombs whose magnetic anomaly is generated by the lack of magnetic materials due to the cavities of the tombs. In the area a diffused magnetisation is manly due to the presence of top soil and tuff materials and high negative susceptibility contrasts can be expected because of the presence of the tombs. The magnetic survey was performed along a regular grid of 0.5 m x 0.5 m using a optical pumped Caesium-vapour magnetometer G858 (Geometrics), in the gradient configuration, on an area which is well known as far as the presence, size and position of tombs are concerne
C'è logica nel pensiero critico?
No full textThis paper gives an account of the experiment of a short series of lectures which was posited by the author at the beginning of the first year of the Degree of Education at the University of Salerno and whose content was the structure of argumentation and the rules of dialogue. If the series of lectures was appreciated by the students, the main difficulty concerned how to introduce and to discuss logic and its basical contents (propositional logic, categorical logic, modalities and so on) in the run of the lectures. The author attempts to show that this introduction is factually necessary even if it stays hard, proposing some ways in order to do that
What is deemed to be "fake"? The case of "fake agricultural workers" in South Eastern Sicily
No full textNel corso dell'articolo, l'autrice affronta il tema dell'economia morale nel mercato del lavoro informale, concentrandosi sul settore serricolo in provincia di Ragusa (Sicilia). L'esperienza etnografica da osservatrice partecipante in uno dei distretti più produttivi dell'agricoltura meridionale, ha aiutato a ricostruire le interazioni che emergono tra lo Stato, gli imprenditori e i lavoratori italiani e migranti, imbrigliati in questo sistema di produzione semi-informale. Il caso dei "falsi braccianti", ovvero di persone ingaggiate in maniera fittizia al fine di ricevere il sussidio di disoccupazione agricola, rappresenta un esempio interessante, poiché consente di indagare alcune categorie, di tipo sia cognitivo che normativo, che costituiscono "l'ordine morale" del mercato del lavoro agricolo locale. L'autrice, dunque, attraverso diversi esempi empirici, cerca di rispondere ad alcune domande rilevanti, come ad esempio cosa è ritenuto "legittimo" o "illegittimo" nell'ambito economico, cosa è costruito come "conveniente" o "valido", e in che modo l'etnicità gioca un ruolo nel definire le strategie d'azione più "appropriate".Throughout this article, the author deals with the topic of the moral economy of the informal labor market, focusing on the greenhouses' sector in the province of Ragusa (Sicily). The ethnographic experience as a participant observer in one of the richest districts of South Italian agriculture, helped to reconstruct the interplay emerging between the State, the entrepreneurs and the Italian and migrants laborers, harnessed in this quasi-informal system of production. The case of "fake agricultural workers", namely of people fictitiously hired in agriculture in order to receive the unemployment subsidy, represents an interesting example, since it allowed to scrutinize some of the categories, both cognitive and normative, that constitute the "moral order" of the agricultural local labor market. The author, thus, through several empirical examples, tried to rep to some relevant questions, like what is deem to be "legitimate" or "illegitimate" in the economic realm, what is constructed as "convenient" or "valuable" and how does ethnicity play a role in defining the "appropriateness" of individuals’ coping strategies
L'action des créatures et le concours de Dieu chez Leibniz: entre trans-créationnistes et durandiens
No full text40. fascicolo degli "Studia Leibnitiana Sonderhefte", il libro analizza l'influenza storica e i contenuti degli Essais de Théodicée del 1710, composti da un Leibniz quasi anziano ma ancora molto lucido e arrivato nel periodo più maturo della sua produzione filosofica. Il saggio di Francesco Piro analizza il contesto della teoria leibniziana dell'azione, contesto che è dominato ancora soprattutto da grandi opzioni teologiche: Dio soltanto agisce, come affermano Malebranche e gli occasionalisti; oppure: Dio lascia che le creature agiscono, come sostengono i pochi seguaci di Durando di San Porziano; o infine Dio e le creature co-agiscono nel produrre lo stesso identico evento, come sostengono i tomisti e sostiene Leibniz. La posizione di Leibniz è però fondata non sulle tradizionali idee tomistiche, ma su una raffinata e importante distinzione ontologica tra l'evento e l'azione, che sono, pur nella loro identità de facto, aspetti di due modalità di approccio diverse al mondo

No full textThe article aims at understanding the set of meanings, norms,
values and ties affecting the everyday work of different types of
brokers employed within a fruit and vegetable market. The case study
is represented by a market located in Vittoria, the centre of the socalled Transformed Littoral Strip, in South-Eastern Sicily. The local
agricultural district hosts several workplaces devoted to the production
and distribution of crops: seeds companies, nurseries, greenhouses,
packinghouses, and fruit and veg markets. The latter represents the field
of our ethnographic investigation that relied, in particular, on the technique
of shadowing, and on around 50 in-depth interviews. The article deals
with the everyday life of several actors (producers, agents and dealers)
and investigates their negotiations, their worries, their ties. In particular,
the contribution scrutinizes which behaviours are deemed legitimate and
which are stigmatized within the social space of the market, in order to
draw a picture of the moral economy and of the conventions circulating
in this setting. Through a number of ethnographic examples, the article
describes how the economic-regulative sphere is actually connected and
mutually constitutive with the moral-evaluative one
