    Nel secondo capitolo del primo libro della Retorica, definendo la prova basata sull’ethos (1356a 4-13), Aristotele collega la capacità dell’oratore di risultare credibile (pistos) presso il suo uditorio all’epieikeia, una qualità morale tipica del saggio (phronimos) che svolge un ruolo importante anche nella teoria aristotelica della giustizia (EN 1337a 32-1138a 3). In linea generale, la caratteristica specifica dell’epieikes è per Aristotele la capacità di esprimere giudizi e prendere decisioni caso per caso tenendo conto delle circostanze, anche al di là di ciò che è stabilito dalla legge (dikaion). In questo articolo mettiamo in luce come questo riferimento all’epieikeia in ambito retorico offra numerosi spunti di riflessione sulla questione più generale relativa alla valutazione del merito nel discorso pubblico.In the second chapter of the first book of Rhetoric, when Aristotle defines the proof based on the ethos (1356a 4-13), he links the credibility of the speaker to the epieikeia, a moral quality typical of the wise man (phronimos) which plays an important role also in the Aristotelian theory of justice (EN 1337a 32-1138a 3). In general, according to Aristotle the specific characteristic of the epieikes is the ability to make judgments and make case-by-case decisions, taking into account the circumstances, even beyond what is established by law (dikaion). In this article we point out that this reference to epieikeia in the rhetoric offers food for thought on the more general issue concerning the evaluation of merit in public discourse

    Le retoriche della concordia

    L'uso dell'espressione “Les rhétoriques de la concorde”, è la conseguenza di una scelta ben precisa: attribuire una funzione politica al genere epidittico. A questa scelta si possono opporre delle critiche legittime, tenuto conto che le fonti antiche presentano i discorsi epidittici come discorsi di circostanza che ruotano attorno alle nozioni di elogio e di biasimo. L’idea di una funzione politica del genere epidittico si fonda su un’interpretazione inizialmente proposta da Perelman e Olbrechts-Tyteca. A partire da questo - e alla luce dei contributi che la curatela raccoglie - gli autori ragionano sul nesso inscindibile epidittico/politica.The expression "Les rhétoriques de la concorde", is the consequence of a precise choice: assigning a political function to the epideictic genre. This choice can be opposed to legitimate criticism, given that the ancient sources present the epidemic discourses as discourses on circumstance that revolve around the praise and the blame. The idea of a political function of the epidemic type is based on an interpretation initially proposed by Perelman and Olbrechts-Tyteca. Starting from this - and in the light of the contributions that the editors collect - the authors reason about the inseparable epidictic/political link

    Citizens, citizenship and European Union: an open bet? The culture of legality

    Get PDF
    Although the meanings of citizenship, active citizenship and organized crime are still open to debate, we try to show the evaluation of the culture of legality and the investments in social, economic and cultural programs for youth as a major defense for such a capillary phenomenon. There is also general agreement that EU programs for endorsing citizenship and active citizenship represent an effective tool for creating transnational networks of young people committed to EU values. Thus, they perceive the culture of legality as the best form of protection against arbitrary violence with references not only to a developed (and eventually harmonized) system of legal sanctions, but also to the fulfillment of individual and collective freedom. We try to shed light on these concept by teh tools provided by political science and philosophy of language

    Πίστις is said in many ways

    In this article, we will examine some aspects of the Greek notion of pistis (faith, persuasion, belief, confidence, trust, proof, etc.) in two very different fields: the religious one and the rhetorical and philosophical one. We will try to emphasize the rationality of religious pistis and to weaken, in a sense, the rationality of philosophical pistis. In short, we will try that: (1) the distinction between a rational/philosophical pistis (belief founded on rational arguments) and an irrational/religious pistis (belief founded on irrational arguments) is not valid from a theoretical point of view – and not applicable from a practical point of view; (2) the category rational/irrational is not useful to assess the epistemological status of a pistis/belief. To show this, we will refer to New Testament authors and Aristotle, who in some ways can be considered as representing specimens of these two (allegedly) opposite models of pistis

    Influence Of The Electrical Parameters On The Fabrication Of Copper Nanowires Into Anodic Alumina Templates

    Metallic copper nanowires have been grown into the pores of alumina membranes by electrodeposition from an aqueous solution containing CuSO4 .and H3BO3 at pH 3. In order to study the influence of the electrical parameters on growth and structure of nanowires, different deposition potentials (both in the region where hydrogen evolution reaction is allowed or not) and voltage perturbation modes (constant potential or unipolar pulsed depositions) were applied. In all cases, pure polycrystalline Cu nanowires were fabricated into template pores, having lengths increasing with the total deposition time. These nanowires were self-standing, because they retain their vertical orientation and parallel geometry even after total template dissolution. However, the electrical parameters influence the growth rate, length uniformity and crystal size of the nanowires. Continuous electrodeposition resulted in higher growth rates but less uniform lengths of nanowires grown inside different membrane pores, whilst a square pulse deposition produced a slower growth but quite uniform lengths. Also the grain size, of the order of 50 nm, was slightly influenced by the potential perturbation mode

    Fabrication and Photoelectrochemical Behavior of Ordered CIGS Nanowire Arrays for Application in Solar Cells

    In this work, we report some preliminary results concerning the fabrication of quaternary copper, indium, gallium, and selenium CIGS nanowires that were grown inside the channels of an anodic alumina membrane by one-step potentiostatic deposition at different applied potentials and room temperature. A tunable nanowire composition was achieved through a manipulation of the applied potential and electrolyte composition. X-ray diffraction analysis showed that nanowires, whose chemical composition was determined by energy-dispersive spectroscopy analysis, were amorphous. A composition of Cu0.203In0.153Ga0.131Se0.513, very close to the stoichiometric value, was obtained. These nanostructures were also characterized by photoelectrochemical measurements: They showed a cathodic photocurrent and an optical gap of 1.55 eV

    Percutaneous coronary interventions cause frequently an increase in myocardial necrosis markers. Is troponin elevation after percutaneous coronary intervention a predictor of events at follow-up or a consequence of the procedure with no cause-effect relationship with prognosis?
