The strongly innovative theory of whole-parts relations outlined by Husserl in his Third logical Investigation—to which he attributed a basic value for his entire phenomenology—has recently attracted a renewed interest. Although many important issues have been clarified (especially by Kit Fine) the subject seems still worth being revisited. To this aim Husserlian universes are introduced. These are lower bounded distributive lattices endowed with a unary operation of defect and a binary relation of isogeneity. Husserl's contents are identified with nonzero elements (...) of a Husserlian universe and the dependence relations among contents are defined and studied starting from the idea that the defect of xis what x needs in order to ‘exist’ i.e., in order to be ‘closed’ with respect to the closure operation defined as the sup of x and its defect. It turns out that there are (at least) eight dependence relations which are worth to be considered. Many other questions concerning the world of contents (among them the proofs of the famous Husserl's Sätze) may now be discussed and clarified. Then the theory of species and genera is developed. Ultimate species (for short: species) are identified with equivalence classes of contents modulo isogeneity, and species in general (for short: genera) are identified with arbitrary unions of species. On the basis of the relation obtaining among two contents when they are isogeneous to two contents the first of which is a part of the second it becomes possible to develop a rather satisfying interpretation of Husserl's theory of the dependencies among species and genera and of the material a priori laws. By strengthening the notion of Husserlian universe into the notion of rigid Husserlian universe, the theory of species and genera obtains a stronger version. Three models of the theory are exhibited. The first one, suggested by combinatorial-topological considerations, identifies contents with finite non-empty sets of natural numbers; the second one identifies contents with non-empty sets of formulas of a formal language; the third one (not totally ‘rigid’) identifies contents with positive integers.

This article considers the attempt by a prominent fifteenth-century follower of Thomas Aquinas, Dominic of Flanders, to address John Duns Scotus’ most famous argument for the univocity of being. According to Scotus, the intellect must have a concept of being that is univocal to substantial and accidental being, and to finite and infinite being, on the grounds that an intellect cannot be both certain and doubtful through the same concept, but an intellect can be certain that something is a being (...) while doubting whether it is a substance or accident, finite or infinite. The article shows how Flandrensis’ reply in defence of analogy of being hinges on a more fundamental disagreement with Scotus over the division of the logically one. It also shows how Flandrensis’ answer to this question commits him to a position on the unity of the concept of being that lies between the positions of Scotus and of Flandrensis’ earlier Thomistic sources.

This special issue re-evaluates the 1950s as a period of transnationalism in ideas and political practices, offering innovative insights into political history and political ideas. Without setting the national and transnational spheres against each other, the issue argues that the dialectics between the two was a defining element of Europe in this period. The articles explore transnational cooperation and exchanges among intellectuals, politicians and trade unionists, showing how they were changing in their interaction. The editorial sets out from the research (...) on the postwar configuration of Europe based on the retake of the nation state, combining it with new research of transnational history and putting out some methodological innovations. The editorial also highlights some significant themes across the articles: the central role of translation and localisation, the interaction with local interests and disputes, the Cold War, the acceleration of European integration, the rise of the Third World, the tensions between hope and fear or between nihilism and rebirth of Europe, the centrality of science.

Per uscire dalle aporie delle proprie conseguenze, la scienza deve vedere riconosciuto l'atto come uno dei propri principi fondamentali (accanto all'ente e alla parola). Scienza è, infatti, mettere in relazione le cose (la "natura") con delle leggi matematiche (vale a dire con dei simboli e dei concetti). Ma mettere in relazione è un atto. Sicché, la scienza si fonda su tre principi (ente, parola, atto) e sui corrispettivi campi filosofici (ontologia, logica, etica). Tenere conto di quest'ambito triadico serve a mostrare (...) che l'epistemologia non è un sapere neutro e descrittivo, ma è un prendere partito: al tempo stesso dal punto di vista etico, politico, morale e giuridico.

This paper gives two complete and elementary proofs that if the speed of light over closed paths has a universal value c, then it is possible to synchronize clocks in such a way that the one-way speed of light is c. The first proof is an elementary version of a recent proof. The second provides high precision experimental evidence that it is possible to synchronize clocks in such a way that the one-way speed of light has a universal value. We (...) also discuss an old incomplete proof by Weyl which is important from an historical perspective. (shrink)

At the beginning of his influential De Nominum Analogia, Thomas de Vio Cajetan mentions three mistaken positions on analogy. He does not attach names to these positions, but each one was held by distinguished Thomists of the fourteenth and fifteenth centuries. Furthermore, their proponents were responding to the same set of challenges from John Duns Scotus that set the agenda for the De Nominum Analogia. In this paper, I would like to do something that Cajetan did not do, and that (...) is, directly consider the merits of the first position in his list of mistaken accounts of analogy; namely, the position that analogy is constituted by disjunction. More specifically, this paper investigates the polemical use for which Hervaeus Natalis deployed analogy of disjunction; the reply of John Duns Scotus; and the implications of this back and forth for understanding the Thomist-Scotist dispute over the concept of being.

The mental representation of one’s own body does not necessarily correspond to the physical body. For instance, a dissociation between perceived and actual reach-ability has been shown, that is, individuals perceive that they can reach objects that are out of grasp. We presented participants with 3D pictures of objects located at four different distances, namely near-reaching space, actual-reaching space, perceived-reaching space and non-reaching space. Immediately after they were presented with function, manipulation, observation or pointing verbs and were required to judge (...) if the verb was compatible with the object.Participants were faster with function and manipulation verbs than with observation and pointing verbs. Strikingly, with both function and manipulation verbs participants were faster when objects were presented in actual than the perceived reaching space. These findings suggest that our knowledge of the world is implicitly built online through behaviour, and is not necessarily reflected in explicit estimates or conscious representations. (shrink)

The paper examines the all too often neglected role of the Czech philosopher and mathematician Bernard Bolzano for Husserl’s work, from ca. 1893–1894 onwards. Husserl himself finds it important to stress in an appendix to chapter 10 of the Prolegomena to Pure Logic that his investigations are not “in any sense mere commentaries upon, or critically improved expositions of, Bolzano’s thought patterns”, but that they “have been crucially stimulated by Bolzano …”. The paper examines early Bolzano’s ideas on the ground-consequence (...) relation, Bolzano’s logical universe as presented in his masterpiece, the monumental Wissenschaftslehre, the role of Hermann Lotze in making Husserl receptive for Bolzano and, finally, a lecture course on logic held by Husserl at the University of Halle in 1896, working out just what Husserl is taking, and not taking, from Bolzano.

ORCA.IT, a new online test of online research and comprehension was developed for the Italian population. A group of 183 students attending various types of upper secondary schools in Northern Italy were tested with the new tool and underwent further cognitive and neuropsychological assessment. The different school types involved in the study are representative of the school population in the Italian system, but can also be easily compared with the educational systems of other countries. The new test turned out to (...) have good psychometric properties after accurate item construction and final selection. In particular, Version 1 showed better characteristics than Version 2. Subsequently, comparison with one-way ANOVAs were performed to test whether differences exist between different school types, between groups with and without reading difficulties, and between males and females. Such differences are sometimes reported in the literature, but many remain controversial. Further, Pearson’s bivariate correlations were calculated to analyze associations between scores on the ORCA.IT and cognitive/neuropsychological variables. Finally, a stepwise regression analysis was performed on aggregated scores to identify the predictors of performance on each of the two versions, The test, especially in the most complete version (Version 1), appears to accurately and reliably capture students’ web searching abilities and online reading comprehension. The tool could highlight differences in online search and comprehension ability between students with and without reading difficulties, not penalizing overall performance but allowing very specific weaknesses to be pointed out. Further, it seems to be able to capture differences due to both educational pathways (different school types) and social attitudes (differences between males and females). Most interesting, it shows to be clearly resting on specific cognitive and neuropsychological abilities, including language, memory and attentional skills, which explain a large portion of the total variance. Offline text reading comprehension is a crucial predictor of online reading performance, while decoding ability is not. Prior knowledge also influences the results, as expected. The new tool turns out to be rather independent from previous internet experience and to measure more cognitively grounded processes related to information gathering, processing and communicating.

Automation and information technology have transformed the organization of labor to such an extent that the processes of exploitation have moved beyond the labor class and now work upon society as a whole. If this displacement has destroyed the political primacy of the labor class, it has not, however, eliminated exploitation; rather, it has broadened it, implanting it within the given conditions of the most diverse spheres of society. -- from The Winter Is Over In late 1995, in opposition to (...) the conservative agenda of Jacques Chirac and his prime minister Alain Juppé and their proposed widespread welfare cuts, French students rose up against their government; public sector workers, together with all the major trade unions, went on strike. When railway workers and Paris Metro personnel joined in the protests, France's public transportation system came to a halt. These extensive social upheavals, the likes of which had not been seen in France since 1968, found widespread public support and fuelled the creation of many political organizations. Chirac backed down from restructuring the public retirement system. Antonio Negri's _T_he Winter is Over comes out of the glimmer of optimism created by the events of 1995, when the long, cold season of neoliberalism, Thatcherism, Reaganomics, reaction, and counterrevolution appeared to have run its course. Published in Italian in 1996, _The Winter is Over_ brings together a series of articles, speeches, and other documents written by Negri between 1989 and 1995 at the threshold of this thaw. It offers a revealing and wide-reaching account of those years of change and brink-of-change, focusing on such topics as the networks of social production, the decline of "limp thought," the end of applied socialism, the Gulf War, and, finally, Italy's transition to its so-called "Second Republic," as seen by an exile.

Logic was understood by the Stoics in a broad sense, as the doctrine that included analysis of the forms of argumentation, rhetoric, theory of concepts and propositions, epistemology, and philosophy of language. The distinguishing characteristic of Stoic logic is the fact that it is fundamentally a logic of propositions, unlike the logic of terms belonging to the Aristotelian tradition. This study offers a new treatment of Stoic logic, in which the various topics are retraced and critically assessed.

Since the first decade of the 14th Century, Thomas Aquinas’s disciples have struggled to explain and defend his doctrine of analogy. Analogy after Aquinas: Logical Problems, Thomistic Answers relates a history of prominent Medieval and Renaissance Thomists’ efforts to solve three distinct but interrelated problems arising from their reading both of Aquinas’s own texts on analogy, and from John Duns Scotus’s arguments against analogy and in favor of univocity in Metaphysics and Natural Theology. The first of these three problems concerns (...) Aquinas’s at least apparently disparate statements on whether a name is said by analogy through a single concept or through diverse concepts. The second problem concerns the model of analogy suited for predicating names analogously across the categories of being or about God and creatures. Is “being” said analogously about God and creatures, or substance and accidents, on the model of how “healthy” is said of medicine and an animal, or on the model of how “principle” is said of a point and a line? The third problem comes from outside challenges to Aquinas’s thought, in particular Scotus’ claims that univocal names alone can mediate valid demonstrations, and any demonstration that failed to use its mediating terms univocally would fail by the fallacy of equivocation. Analogy after Aquinas makes a unique contribution to the study of philosophical theology in the tradition of Thomas Aquinas by showing the historical and philosophical connection between these three problems, as well as the variety of solutions proposed by leading representatives of this tradition. Thomists considered in the book include: Hervaeus Natalis (1250-1323), Thomas Sutton (1250-1315), John Capreolus (1380-1444), Dominic of Flanders (1425-1479), Paul Soncinas (d. 1494), Thomas dio vio Cajetan (1469-1534), Francis Silvestri of Ferrara (1474-1528), and Chrysostom Javelli (1470-1538).

Fifty-plus years ago, Ralph McInerny’s The Logic of Analogy characterized Francis Silvestri of Ferrara’s doctrine of analogy as a confusing hybrid of the thought of Thomas Aquinas and of Thomas Cajetan. Since then, scholarship on fifteenth-century Thomism has flourished, thanks especially to the efforts of Ashworth, Bonino, Hochschild, Riva, and Tavuzzi. In light of these decades of scholarship, in this article I reconsider Francis Silvestri’s doctrine of analogy. I attempt to show the merits of his contribution to the Thomist tradition’s (...) ongoing reflection on analogy, especially the dispute among Thomists and with Scotists over abstracting an analogous concept, the unity of the concept used analogously, and the use of analogy in demonstration. I argue that Francis’s hybrid succeeds in finding a place for analogy of attribution in names said analogously of God and creatures while still meeting Cajetan’s standards for answering Scotist objections to demonstration through analogous terms.

Abstractabstract:Aristotle identifies four modes of unity: numerical, specific, generic, and proportional or analogous. Recent scholarship has renewed the Renaissance and early Modern Thomist critique that John Duns Scotus's (d. 1308) doctrine of the univocity of being is based on a failure to appreciate proportional unity. This paper attempts to fill a gap in the copious literature on Scotus's doctrine of the univocity of being by presenting and offering an analysis of the texts where Scotus addresses the topic of proportional or (...) analogous unity. The paper argues that Scotus's early and mature works consistently reject the notion that an analogous or proportional unity can serve as the foundation for greater than equivocal unity between concepts, and that Scotus's developed position represents an alternative to Aristotle's division of unity into the modes of numerical, specific, generic, and analogous. Nonetheless, Scotus's early remarks on an analogous unity that is mind-independent provide both an internal justification for the dispute that ensues between Thomists and Scotists over whether a single concept can signify analogously—a dispute that features such distinguished participants as Thomas de Vio Cajetan (1469–1534) and Bartolomaeus Mastrius (1602–73)—and an avenue for further investigation into the thought of the Subtle Doctor.

Dapprima due indizi. Il primo: si può affermare che le due domande “Come si chiama il libro che stai leggendo?” e “Come si intitola il libro che stai leggendo?” siano immediatamente comprensibili ed equivalenti. Difficilmente però un parlante sente come equivalenti le domande “Come si chiama quell’edificio?” e “Come si intitola quell’edificio?”. Mentre la prima domanda è chiarissima, la seconda susciterà un’ulteriore domanda di chiarimento: “Che cosa intendi per titolo dell’edificio?”. Per un...
