Verità instabili. L'eikos in Aristotele
2012
This paper deals with the Aristotelian concept of eikos, traditionally translated as “probability” or “likelihood", with the aim of showing the complexity and the theoretical worth of this notion. Eikos has already been an important concept in fields such as historiography and rhetoric and it plays a crucial role in Aristotelian thought, as well. According to Aristotle, eikos does not oppose itself to truth nor is it a second-level knowledge. Instead, it is a heuristic device that is extremely useful in conditions of uncertainty. Aristotle’s task was to offer a personal elaboration of a concept that already had a rich background and was suited to become a means for reflection on a crucial p…
Are Humans Poor at Arguing? From the ‘Argumentative Theory of Reasoning’ back to a Rhetorical Theory of Argumentation
2018
Starting from Sperber and Mercier’s theory (2011) on the relationship between reasoning and arguing, we will try to rethink the link between rhetoric and argumentation. Using Aristotelian rhetoric as a theoretical framework, we will focus on two related features: 1) the nature and the role of argumentation inferences in classical models of rhetoric; 2) the role of normativity in assessing a naturalistic description of what we make when we argue.
Rhetorical deliberation. A sustainable normativism from a Gorgianic-Aristotelian perspective
2018
Starting from the discursive turn that has characterized democracy since the 80s of the last century, our article tries to outline a form of sustainable normativism. To do this, we use a theoretical framework derived from ancient Greek rhetoric and in particular from the reflection of Gorgias and Aristotle. In our perspective, on the one hand, the Gorgianic view is a useful reminder of the role that the pursuit of power and the possibility of conflict unavoidably play in the form of argumentation specific to the public sphere, that is, deliberation. On the other hand, Aristotle, thanks to his emphasis on the link between logos and desire and his analysis of truth available in deliberative c…

Il secolo lungo della modernità. Il museo immaginato
2012
Abbiamo ipotizzato un museo diverso, luogo della fantasia e dell'immaginazione, in un'ipotetica città d'Europa che da qui vuole ripartire per il riordino urbanistico del suo centro utilizzando la vecchia stazione ferroviaria ormai dismessa." In questo libro Philippe Daverio ci accompagna alla scoperta dell'età moderna, ovvero del Secolo Lungo che parte dalla Rivoluzione francese e finisce nella catastrofe della Prima guerra mondiale. Questo volume affronta i temi più importanti della modernità attraverso oltre seicento opere d'arte raccolte tematicamente per vettori storici: quello politico, da Delacroix e Géròme al Quarto stato di Pellizza da Volpedo; quello della macchina e del lavoro, da…

Revising the predictions of inflation for the cosmic microwave background
2009
We point out that, if quantum field renormalization is taken into account and the counterterms are evaluated at the Hubble-radius crossing time or few e-foldings after it, the predictions of slow-roll inflation for both the scalar and the tensorial power spectrum change significantly. This leads to a change in the consistency condition that relates the tensor-to-scalar amplitude ratio with spectral indices. A reexamination of the potentials ϕ2 and ϕ4 shows that both are compatible with five-year WMAP data. Only when the counterterms are evaluated at much larger times beyond the end of inflation does one recover the standard predictions. The alternative predictions presented here may soon co…
Evaporation of Near-Extremal Reissner-Nordström Black Holes
2000
The formation of near-extremal Reissner-Nordstrom black holes in the S-wave approximation can be described, near the event horizon, by an effective solvable model. The corresponding one-loop quantum theory remains solvable and allows to follow analytically the evaporation process which is shown to require an infinite amount of time.
