Il presente lavoro può essere letto come un manuale di metodologia lessicografica nella documentazione linguistica nell'opera di Tommaso d'Aquino e come saggio ermeneutico sul concetto tommasiano di comunicazione come sistematica riflessione metafisica sull'atto di comunicare.

L'A. présente un ouvrage écrit par le Père Roberto Busa et paru récemment : Richerche lessicologiche. Il s'agit d'un travail lexicologique sur le vocabulaire employé par saint Thomas d'Aquin pour élaborer son système ontologique. L'A. dénombre et décrit les nouvelles acquisitions linguistico-ontologiques que ce travail a permis dans le champ du thomisme. Elles sont au nombre de trois : l'hétérogénéité sémantique des mots, la segmentation morphothématique des lemmes, les terminaisons latines.

The semantical structures called T×W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, ℒO, which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator ⋄. However, these structures are also suitable for interpreting an extended language, ℒSO, containing a further possibility operator ⋄s which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history ‘simultaneity’ operator. In the present paper we provide (...) an infinite set of axioms in ℒSO, which is shown to be strongly complete forT ×W-validity. Von Kutschera (1997) contains a finite axiomatization of T×W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions. (shrink)

In the context of a wider investigation into Christianity as dialogue with non-Christians, and following up on a study of the approach of Thomas Aquinas through «demonstrative or probable reasons», the present study examines the approach of Francis of Assisi, who went off to preach to the Sultan and ordered his friars to give witness to the Gospel without resorting to discussions or conflicts, and that of Bonaventure, who, like Paul in the First Letter to the Corinthians, insisted on the (...) power of the signs of God and of his Word.

The modern concept of 'dialogue' among persons and groups of different religions or 'world-views' is the fruit of interaction between Christian tradition and the technique of dialogue in Greek philosophy. Dialogue in general requires a classification of those in dialogue , a prototype and an archetype of mediation , a teleotype or final objective , a procedural type , and a representation of spacial logic . This article examines especially the Thomistic approach, through demonstrative and probable reasons.

In this thesis I defend and pursue that line about the foundations of probability theory which has come to be known as "the logicist view about probability", and, in particular, the shape which it took in Carnap's Inductive Logic. ;Most philosophers who now deal with probability theory claim that Carnap's program of Inductive Logic has failed. The main aim of my thesis is to show that this judgment is based on a fundamental misunderstanding about the nature and the aim of (...) inductive logic. To that end, I follow, in chapter 1, the events in the history of probability, logic and mathematics which led to choosing certain requirements as the requirements which any theory about the foundations of probability must fulfill in order to be acceptable. ;In chapter 2 I explain how Carnap's inductive logic fulfills those requirements and how the method it uses to give foundations to probability theory can also be used to solve another major problem about probability, namely, the problem of statistical inference. ;Chapter 3 shows how the ideas explained in chapter 2 were developed, formally, by Carnap, and how Carnap's program can be continued in a particular case, that of reasoning by analogy. ;Finally, in chapter 4, I attempt to show that subjectivism about probability theory, the rival theory to Carnap's logicism, does not succeed in meeting the most basic requirement for the acceptability of any theory about the foundations of probability.

On the historiographic plane, the confrontation between the texts of Bonaventure and of Thomas Aquinas regarding the structure of human knowledge, reveals common features and divergent ones. Both are, moreover, «scholastics» in the elaboration of the sources, in so far as they do not select only some data of tradition , but seek through various paths to assume and to synthetise coherently the whole tradition known to them. Bonaventure has followed the path of extrapollation of the single data from their (...) original context and of their insertion into a schema altogether traditional as to the content, but altogether new as for the structure. Thomas, on the contrary, has chosen the way of composition of the data through the concordance and the hierarchy of the schema, giving clearly the epistemological primacy to the Aristotelian system, but without showing himself ever fully satisfied with the schemata obtained. In articulating philosophy and theology Thomas et Bonaventure share the paradigm of the «double in parallel», bringing it perhaps to the extreme rigour, though with different nuances: Thomas by showing the natural basis of the supernatural perfection, and Bonaventure by showing the necessity and the natural impossibility of such perfectioning.

Ponto de partida do artigo é a consideração de que o problema da relação entre Filosofia e Espiritualidade, ainda que problemático, é filosoficamente pensável e pode ser historicamente reconstruído. Com efeito, o artigo mostra de que modo o problema foi objecto de uma sistematização paradoxal, ainda que coerente e exemplar, por parte de S. Boaventura, cuja reflexão, tematizando a espiritualidade minorítica, radica em S. Francisco de Assis, ainda que também através da mediação de Santo António de Lisboa. Segundo S. Boaventura, (...) Deus manifesta-se de forma natural no livro da natureza mediante o Verbo incriado, cognoscível mediante a razão natural na ciência natural, que é a Filosofia; e revela-se sobrenaturalmente no livro da Escritura mediante o Verbo incarnado, cognoscível mediante a razão iluminada pela fé na ciência sobrenatural, que é a Teologia; mas também se comunica pessoalmente e concretamente no coração dos crentes mediante o Verbo inspirado, ou seja, o Cristo feito presente pelo Espírito Santo na "vida espiritual", num processo ascético-místico, cujo primeiro estádio é, paradoxalmente, a própria Filosofia, aqui entendida como a busca da sabedoria através das virtudes cardeais. Por outro lado, o artigo mostra também como o próprio paradigma da reedificação interior através das virtudes parece estabelecer um vínculo entre S. Francisco de Assis e Santo António de Lisboa, bem como entre os dois e S. Boaventura, o qual, hipotiza o autor do artigo, não só leu alguma coisa dos Sermões de Santo António, como deles retirou elementos para as suas reflexões mais maduras. /// The starting point of this article is the consideration that the problem of the relation between Philosophy and Spirituality, even if problematic, can be philosophically thought and historically reconstructed. In effect, the article shows how this problem was object of a paradoxical systematization, coherent and exemplar, on the part of Saint Bonaventure, whose reflection, typical of the Franciscan spirituality, is rooted in Saint Francis of Assisi, even if also through the mediation of Saint Anthony of Lisbon. According to Saint Bonaventure, God reveals Godself naturally in the Book of nature by means of the uncreated Logos, knowable through natural reason in the natural science, which is Philosophy; and God reveals Godself supernaturally in the Book of Scripture by means of the incarnated Logos knowable by means of reason illuminated by faith in the supernatural science, which is Theology; but God also communicates Godself personally and concretely in the hearts of the believers by means of the inspired Logos, i.e., the Christ made present through the Holy Spirit in the "spiritual life", in an ascetic-mystical process, whose first stage is, paradoxically, Philosophy itself, here understood as the search for Wisdom through the cardinal virtues. On the other hand, the article also shows how the paradigm of the interior edification through the virtues seems to establish a link between Saint Francis of Assisi and Saint Anthony of Lisbon, as well as between the two and Saint Bonaventure, who, according to the article, not only has read something of Saint Anthony's Sermons, but also has taken something from them for his mature reflexions.

The λ-continuum of inductive methods was derived from an assumption, called λ-condition, which says that the probability of finding an individual having property $x_{j}$ depends only on the number of observed individuals having property $x_{j}$ and on the total number of observed individuals. So, according to that assumption, all individuals with properties which are different from $x_{j}$ have equal weight with respect to that probability and, in particular, it does not matter whether any individual was observed having some property similar (...) to $x_{j}$ (the most complete proof of this result is presented in Carnap, 1980). The problem thus remained open to find some general condition, weaker than the λ-condition, which would allow for the derivation of probability functions which might be sensitive to similarity. Carnap himself suggested a weakening of the λ-condition which might allow for similarity sensitive probability functions (Carnap, 1980, p. 45) but he did not find the family of probability functions derivable from that principle. The aim of this paper is to present the family of probability functions derivable from Carnap's suggestion and to show how it is derived. In Section 1 the general problem of analogy by similarity in inductive logic is presented, Section 2 outlines the notation and the conceptual background involved in the proof, Section 3 gives the proof, Section 4 discusses Carnap's principle and the result, Section 5 is a brief review of the solutions which have previously been proposed.

The semantical structures called T x W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, $[Unrepresented Character]_{o}$ , which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator ◇. However, these structures are also suitable for interpreting an extended language, $[Unrepresented Character]_{so}$ , containing a further possibility operator $\lozenge^{s}$ which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history 'simultaneity' operator. (...) In the present paper we provide an infinite set of axioms in $[Unrepresented Character]_{so}$ , which is shown to be strongly complete for T x W-validity. Von Kutschera (1997) contains a finite axiomatization of T x W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions. (shrink)

An ethical conflict arises when we must perform research in the interest of future patients, but that this may occasionally injure the interests of today''s patients. In the case of cognitively impaired persons, the question arises whether it is compatible with humane healthcare not only to treat, but also to use these patients for research purposes. Some bioethicists and theologians have formulated a general duty of solidarity, also pertaining to cognitively impaired persons, as a justification for research on these persons. (...) If one examines this thesis from the theory of justice according to John Rawls, it is revealed that such a duty of solidarity cannot necessarily be extrapolated from Rawls' conception of justice. This is at least true of Rawls' difference principle, because accordingto the difference principle only those measures are justifiable which serve the interest of the respective least well off. Those measures which would engender additional injury for the least well off could not be balanced by any utility according to Rawls. However, John Rawls' difference principle is subordinate to the first principle, which is that each person has an equal right to the most extensive basic liberty compatible with the same liberty for others. These primary goods are determined by the freedom and integrity of the person. This integrity of decisionally impaired persons would be in danger if one would abstain from research and thus forego the increase in knowledge related to their disease. Thus one could conclude, at least from Rawls' first principle, that society must take on a duty to guarantee the degrees of freedom for cognitively impaired persons and thus also support the efforts for their healing.

T × W logic is a combination of tense and modal logic for worlds or histories with the same time order. It is the basis for logics of causation, agency and conditionals, and therefore an important tool for philosophical logic. Semantically it has been defined, among others, by R. H. Thomason. Using an operator expressing truth in all worlds, first discussed by C. M. Di Maio and A. Zanardo, an axiomatization is given and its completeness proved via D. Gabbay’s (...) irreflexivity lemma. Given this lemma the proof is more or less straight forward. At the end an alternative axiomatization is sketched in which Di Maio’s and Zanardo’s operator is replaced by a version of “actually”.

The extracellular‐signal regulated kinases 1/2 (ERK or ERKs) are involved in the regulation of important neuronal functions, including neuronal plasticity in normal and pathological conditions. We present findings that support the notion that the kinetics and localization of ERK are intrinsically linked, in that the duration of ERK activation dictates its subcellular compartmentalization and/or trafficking. The latter, in turn, dictates whether ERK‐expressing cells would enter a program of cell death, survival or differentiation. We summarize experimental data showing that chronic activation (...) of ERK plays a role in the mechanisms that trigger neurodegeneration. We also discuss how MKPs, members of the subclass of dual specificity phosphatases, might be the link between ERK kinetics and its subcellular localization.

The discovery of neurogenesis and neural stem cells (NSC) in the adult CNS has overturned a long‐standing and deep‐routed “dogma” in neuroscience, established at the beginning of the 20th century. This dogma lasted for almost 90 years and died hard when NSC were finally isolated from the adult mouse brain. The scepticism in accepting adult neurogenesis has now turned into a rush to find applications to alleviate or cure the devastating diseases that affect the CNS. Here we highlight a number (...) of methodological, technical and conceptual drawbacks responsible for the historical denial of adult neurogenesis. Furthermore, we discuss old and new issues that need to be faced before NSC or endogenous neurogenesis can safely enter into the doctor's bag for therapies.

RésuméLa tradition manuscrite duKitāb al-Kašf, conserve la trace matérielle de trois phases de rédaction et de révision de l'ouvrage. Cette étude vise à expliciter les relations entre les deux versions arabes et la traduction hébraïque anonyme du XIVesiècle, en prenant en compte les additions et remaniements qui les différencient. Je conclus que la traduction hébraïque représente un stade intermédiaire de réélaboration: elle atteste d'importants ajouts et modifications philosophiques, spécialement dans les arguments portant sur la création du monde, au début de (...) l'ouvrage, mais précède l'achèvement de la révision du traité, qui a conduit aux remaniements dont témoigne la dernière version arabe, dans les chapitres abordant les questions épineuses de la corporéité divine et de la direction. L'étude des ajouts et des arguments du point de vue du contenu, du contexte et de l'argumentation contribue également à comprendre l'histoire de la stratification des phases rédactionnelles de l'ouvrage et la manière dont l'ouvrage a été transmis.

This paper explores gender differences in “make-up” and “suspicion” in a bargaining game in which the privately informed seller of a company sends a value message to the uninformed potential buyer who then proposes a price for the company. “Make-up” is measured by how much the true value is overstated, “suspicion” by how much the price offer differs from the value message. We run different computerized treatments varying in information about the gender and in embeddedness of gender information. The asymmetry (...) of the game and of information allows for a robust assessment of gender effects. We report here the results from just one shot round decision since we expect such effects to be more pronounced for inexperienced participants. We mainly find an effect of gender constellation: when female sellers are aware to confront a female buyer, they overstate more, i.e. there is more “make-up”. However, we cannot confirm gender effects for suspicion. (shrink)
