The papers presented in this volume in honour of Alfonso Maieru cover some of the major topics of his research area. The institutional and intellectual life of university training in the Middle Ages, including the peculiar tradition of related works, is the focus of the papers by Louis Jacques Bataillon, William J. Courtenay, Jacqueline Hamesse, Zenon Kaluza, Loris Sturlese and Olga Weijers. Three papers, by Jacopo Costa, Pasquale Porro and Thomas Ricklin, deal with philosophical problems in Dante'sMonarchia and Convivio. (...) The complex interrelations between logic and the other main aspects of medieval philosophy, with a particular attention to theology, metaphysics and natural philosophy, are the core of the other papers by Stefano Caroti, Sten Ebbesen, Barbara Faes de Mottoni, Simo Knuuttila, Alain de Libera, Olga Lizzini, Costantino Marmo, Claude Panaccio, Ivan Bendwell, Irene Rosier-Catach, Lambert Marie de Rijk, Leonardo Sileo, Luisa Valente, and Albert Zimmermann. A larger number of friends and colleagues of Alfonso Maieru than those who appear as contributors and editors of this volume have warmly welcomed its publication. We could say, therefore, that it is absolutely contingent that the Editors are: Stefano Caroti (Universita degli Studi di Parma), Ruedi Imbach (Universite de Paris-Sorbonne), Zenon Kaluza (Centre d'Etudes des Religions du Livre, C.N.R.S), Loris Sturlese (Universita degli Studi di Lecce) and Giorgio Stabile(Universita degli Studi di Roma "La Sapienza").

Nel 2011 sono mancati Paolo Lucentini e Alfonso Maierù. Nel ricordarne la vicenda umana e professionale come ricercatori e come docenti, questo articolo intende mettere in luce in particolare il contributo che essi hanno dato alla Storia del pensiero medievale accompagnando gli studi dottrinali con importanti edizioni di testi inediti. Paolo Lucentini and Alfonso Maierù passed away in 2011. This article, in remembrance of their personal and professional roles as researchers and teachers, will highlight the contributions (...) that they made to the history of medieval thought, showing how they combined doctrinal studies with important editions of unedited texts.

In a recent paper, Berger and Nanay consider, and reject, three ways of addressing the phenomenon of unconscious perception within a naïve realist framework. Since these three approaches seem to exhaust the options open to naïve realists, and since there is said to be excellent evidence that perception of the same fundamental kind can occur, both consciously and unconsciously, this is seen to present a problem for the view. We take this opportunity to show that all three approaches considered remain (...) perfectly plausible ways of addressing unconscious perception within a naïve realist framework. So far from undermining the credibility of naïve realism, Berger and Nanay simply draw our attention to an important question to be considered by naïve realists in future work. Namely, which of the approaches considered is most likely to provide an accurate account of unconscious perception in each of its purported incarnations? (shrink)

The aim of our experiment was to analyse the effect of the emotional valence (positive, negative, or neutral) on true and false recognition, matching the arousal, frequency, concreteness, and associative strength of the study and recognition words. Fifty younger adults and 46 healthy older adults performed three study tasks (with words of different valence: positive, negative, neutral) and their corresponding recognition tests. Two weeks later, they performed the three recognition tests again. The results show that words with a negative valence (...) produced less true recognition and less false recognition than words with a positive or neutral valence, in both younger and older adults, on the immediate recognition test. This pattern of results was also found in the younger adults on the delayed recognition test, whereas in the older participants, these differences disappeared. Thus, when arousal is controlled, both younger and older adults tend to recognise negative information worse than positive or neutral information, but they also commit fewer errors. Results would suggest that the greater arousal commonly associated with negative stimuli, rather than their own valence, could explain some of the contradictory results found in the literature.

This paper has two sections: first, I am going to analyze two criteria to differentiate between argumentation and formal demonstration. According to Perelman (Perelman & Olbrechts-Tyteca, 1989) argumentation is based on persuasion, and that is the reason why argumentation is polysemic, ambiguous; on the other hand, it is said that argumentation depends on the additional information that someone gives to us, while demonstration does not depend to the additional information. I will show that no criteria invoked to justify the disctintion (...) between demostration and argumentation is kept. In the second section I will show that persuasion is not necessarily associated to the speech act of argumentation, in the same way that the atempt of convincing is not necessarily associated with the act of asserting something. Thus, someone cannot use persuasion to define the argumentative exercise. (shrink)

In this paper I will present a visual method that I have created to demonstrate the validity of propositional arguments and predicates, based on the traditional Venn diagrams. This idea was born after becoming aware of how useful visual methods are in other scientific fields, such as geometrical representations of arithmetic and algebraic concepts. This method illustrates the relationship between propositional logic, predicate logic and set theory, and it can be used to explain linguistic semantic concepts such as synonymy, antonymy, (...) hyponymy, entailment, and lexical substitution.

What ethical framework should be used as a basis for teaching business ethics? Should business ethics be taught by ethicists in a separate course, by business faculty in business courses, or perhaps by both? These are some of the issues this paper will address. The paper begins with a review of the literature concerning approaches to teaching business ethics. Next, some ethical frameworks for teaching business ethics are considered. Finally, the paper proposes that students should apply their own personal values (...) to business ethical issues in the classroom, thus providing future business leaders with a process for resolving ethical dilemmas.

Una aproximación a la concepción viquiana del Derecho Romano que, desde la "soledad" vivida por el filósofo napolitano, asume como modo original de afrontar el derecho una poética jurídica y la búsqueda de una lengua articulada universal .An approach to Vico's conception of Roman Law that, from the "loneliness" of the napolitan philosopher, assumes juridical poetics as an original way of facing law, and the search of an articulated universal language.

This paper articulates and argues for the plausibility of the Presentation View of Perceptual Knowledge, an under-discussed epistemology of perception. On this view, a central epistemological role of perception is that of making subjects aware of their surroundings. By doing so, perception affords subjects with reasons for world-directed judgments. Moreover, the very perceived concrete entities are identified as those reasons. The former claim means that the position is a reasons-based epistemology; the latter means that it endorses a radically anti-psychologist conception (...) of reasons. First, I articulate and motivate the Presentation View. Then, I defend the view from three incarnations of a major objection levelled within the ranks of reasons-based epistemologies: McDowell’s version of the accusation that a view like this falls prey to the Myth of the Given. I argue that all three incarnations fail to show the Presentation View to be inadequate. The first version holds that a general characterization of the Myth clearly shows that it is an incoherent idea. The second version holds that endorsing the Myth makes it impossible to construe non-conceptual items as items that can stand in rational relations to judgements and beliefs. The third version holds that endorsing the Myth leads to a conception where perceptual experiences merely cause, but do not warrant, our perceptual beliefs and judgements. I explain in detail how the Presentation View has the elements to respond to each of these objections. (shrink)

The merging/fusion of belief/data collections in propositional logic form is a topic that has received due attention within the domains of database and AI research. A distinction can be made between two types of scenarios to which the process of merging can be applied. In the first type, the collections represent preferences, such as the voting choices of a group of people, that need to be aggregated so as to give a consistent result that in some way best represents the (...) collective judgement of the group. In the second type, the collections represent factual data that is to be aggregated with an aim of obtaining a result that maximises factual correctness. After introducing a general framework for belief merging via some prominent literature on the topic, this paper then introduces and considers a method for belief merging with the second type of scenario in mind. Its suitability is corroborated by demonstrating how it can be seen as a special case of a merging procedure that combines aggregation of probabilities and maximisation of expected truthlikeness.

Riassunto : Questo articolo propone un confronto tra la teoria mente-corpo di Henri Bergson e gli ultimi sviluppi della filosofia della mente e, più specificamente, con il cosiddetto “esternalismo”. Lo scopo è duplice. In primo luogo, si vuole sostenere che l’opera del filosofo francese ha anticipato i principali punti teorici dell’esternalismo: la teoria della percezione di Bergson, infatti, ha molti e rilevanti tratti in comune con la cosiddetta 4E Cognition, che finora non sono stati adeguatamente riconosciuti. In secondo luogo, l’articolo (...) intende anche mostrare come il quadro ontologico in cui Bergson colloca la propria interpretazione dell’esperienza cosciente, possa fungere da utile riferimento per il modello esternalista, al fine di sistematizzare i dati sperimentali entro un orizzonte teorico coerente. La teoria della "percezione pura" di Bergson, infatti, supera il modello correlazionista dell’esperienza, rilevando come quest’ultima, allo stato puro, si collochi nelle cose stesse, a un livello di realtà che precede la divaricazione dell’esperienza tra soggetto e oggetto, livello che deve essere pensato come l’origine impersonale della coscienza soggettiva. Parole chiave: Esternalismo; Percezione; Azione; Problema mente/corpo The mind/body problem in Henri Bergson e the externalism in philosophy of mind. Towards an ontological model: In this article we contrast Henri Bergson’s mind-body theory with the latest developments in Philosophy of Mind, more specifically, in so-called “Externalism”. This paper has two specific aims. First, we argue that the work of this French philosopher anticipated the main theoretical concepts of Externalism. Indeed, Bergson’s theory of perception shares many important features, which have not been adequately recognized until now, with so-called 4E Cognition. Second, we show how Bergson’s basic ontology, which frames his interpretation of conscious experience, could offer a coherent theoretical framework to systematize experimental data in an externalist model. Bergson’s theory of “pure perception” goes beyond correlation, showing that our experience, in its purest state, takes place within things themselves, at a level of reality that precedes the bifurcation of experience into a subject and an object. This undivided level of reality can be considered the impersonal origin of subjective consciousness. Keywords: Externalism; Perception; Action; Mind/Body Problem. (shrink)

In this paper I propose a set-theoretical interpretation of the logical square of opposition, in the perspective opened by generalized quantifier theory. Generalized quantifiers allow us to account for the semantics of quantificational Noun Phrases, and of other natural language expressions, in a coherent and uniform way. I suggest that in the analysis of the meaning of Noun Phrases and Determiners the square of opposition may help representing some semantic features responsible to different logical properties of these expressions. I will (...) conclude with some consideration on scope interactions between quantifiers. (shrink)

RESUMEN: Objetivo. En este trabajo se plantea como objetivo examinar y comparar las diferentes concepciones de responsabilidad y relación con “el Otro” en dos diferentes autores representativos que han tratado de forma notable estos conceptos, profundizando en la subjetividad, libertad y la experiencia del mundo y de la propia existencia. Diseño. Se trata de un Estudio en forma de breve ensayo con un análisis crítico de la temática analizada. Originalidad /valor. Se trata de un análisis comparativo entre dos grandes filósofos (...) enmarcados en la fenomenología de la existencia en aspectos concretos de su pensamiento. Hallazgos. Los dos autores que analizaremos han conocido la fenomenología de Husserl y Heidegger, que fue para ellos un punto de partida con gran influencia en su pensamiento, no obstante, ambos autores tuvieron un posicionamiento y desarrollo propio y en parte divergente entre ellos en gran parte de su pensamiento, llegando a constituirse como auténticas referencias de su tiempo y que actualmente mantienen un gran interés e influencia en la filosofía contemporánea. Analizaré comparativamente dos grandes autores como son, Emmanuel Lévinas y Jean Paul Sartre. Conclusiones. En ellos veremos formas diferentes y hasta cierto punto complementarias de abordar la libertad, responsabilidad y la relación con el otro, en uno de forma más ontológica y en el otro con una visión desde la ética.

The purpose of this paper is to look at some existing methods of semantic information quantification and suggest some alternatives. It begins with an outline of Bar-Hillel and Carnap’s theory of semantic information before going on to look at Floridi’s theory of strongly semantic information. The latter then serves to initiate an in-depth investigation into the idea of utilising the notion of truthlikeness to quantify semantic information. Firstly, a couple of approaches to measure truthlikeness are drawn from the literature and (...) explored, with a focus on their applicability to semantic information quantification. Secondly, a similar but new approach to measure truthlikeness/information is presented and some supplementary points are made. (shrink)

Scant attention has been paid to the notion of property in Hannah Arendt’s thought, and this paper aims to address this gap. For Arendt, property is the realm of privacy, located in the house. She argues that the modern age represented its loss with the expropriation of the peasant classes after the Reformation. As a result, wealth started to be accumulated and became productive through the labor of the new propertyless classes. This new way of dealing with property needed a (...) new notion of property for the laborers. Locke’s understanding gave the laborers the hope of being property-owners through their labor and simultaneously justified the unending accumulation of money; nevertheless, property in its true meaning was never recovered. Arendt believes that recovering property under conditions of equality is an essential consideration, and this egalitarian vision of property only can be achieved if law protects prop- erty as well as set limits on the accumulation of wealth.

Freedom and law in Hannah Arendt’s thought are not spontaneously compatible and one might think they are almost impossible to occur together. Due to the importance of both freedom and law this might be considered Arendt’s greatest puzzle. Many scholars have addressed this problem but few have paid attention to the answers to this difficulty she found in political events and to the eventual solution to this puzzle, the phenomenon of civil disobedi-ence. This paper aims to address this gap.

La filosofía helenística es producto de un curso impartido en la Facultad de Filosofía y Letras de la UNAM por Alfonso Reyes, quien a su gran formación filosófica unía extraordinaria sapiencia del mundo griego. El libro se divide en tres partes que comprenden desde la filosofía alejandrina hasta el periodo ético y religioso de los griegos, con lo que se completa el cuadro de la filosofía helenística.

The purpose of this paper is to show how the paradox of knowability loses its paradoxical character when we correctly interpret one of its premises. It is then shown how this new interpretation can be used to logically define analytical and synthetic truths. In this way, the paradox of knowability is traced back to the harmless affirmation that, in order to know every proposition with certainty, there must be no propositions whose truth is synthetic.
