Criticisms à la Laudan can block the “no miracles” argument for the (approximate) truth of whole theories. Realists have thus retrenched, arguing that at least the individual claims deployed in the derivation of novel predictions should be considered (approximately) true. But for Lyons (2002) there are historical counterexamples even to this weaker “deployment” realism: he lists a number of novel predictions supposedly derived from (radically) false claims. But if so, those successes would seem unexplainable, even by Lyons’ “modest surrealism” or (...) other surrogates to realism. In fact, I argue, some of those predictions were an easy guess, or independently probable in the light of available evidence; hence, they are no counterexamples to deployment realism, for the no miracles argument wouldn’t apply to them. In other instances, pace Lyon, the prediction was actually false, and could be reinterpreted as true only by interpreting as true also the claim from which it was derived; or again, a false claim was employed in the derivation of a true prediction, but inessentially, the essential role being played by a weaker true claim. But as soon as the paradoxical air of such historical cases is explained away in any of these manners, they cease to represent counterexamples to deployment realism. If, as I suggest, all of them can be dealt with by these strategies, a theoretical claim can still be assumed to be true if it is crucial in deriving an improbable novel prediction. (shrink)

Let M be an o-minimal expansion of a real closed field. Let G be a definably compact definably connected abelian n-dimensional group definable in M. We show the following: the o-minimal fundamental group of G is isomorphic to ℤn; for each k>0, the k-torsion subgroup of G is isomorphic to n, and the o-minimal cohomology algebra over ℚ of G is isomorphic to the exterior algebra over ℚ with n generators of degree one.

L'autore parte dall'analisi dei problemi etici espressi nei linguaggi della poesia, della tragedia e della storiografia, per passare poi alla lettura delle maggiori opere del pensiero antico, fornendo di ognuna puntuali introduzioni. Un'attenzione particolare, alla fine di ogni capitolo, è dedicata all'eredità moderna e al significato attuale dei problemi dell'etica antica, proponendo in modo esplicito un collegamento fra ricostruzione storica e discussione teorica contemporanea.

This book presents a philosophical interpretation to numerical cognition based on dual process theories and heuristics. It shows how investigations in cognitive science can shed light on issues traditionally raised by philosophers of mathematics. The analysis will also help readers to better understand the relationship between current neuroscientific research and the philosophical reflection on mathematics. The author seeks to explain the acquisition of mathematical concepts. To accomplish this, he needs to answer two questions. How can the concepts of approximate numerosity (...) become an object of thought that is so accessible to our consciousness? How are these concepts refined and specified in such a way as to become numbers? Unfortunately, there is currently no model that can truly demonstrate the role of language in the development of numerical skills starting from approximate pre-verbal skills. However, the author details a solution to this problem: dual process theories. It is an approach widely used by theorists focusing on reasoning, decision making, social cognition, and consciousness. Here, he applies this approach to the studies on mathematical knowledge. He details the results brought about by psychological and neuroscientific studies conducted on numerical cognition by key neuroscientists. In the process, he develops the foundations of a new, potential philosophical explanation on mathematical knowledge. (shrink)

The contrast between the past-future symmetry of mechanical theories and the time-arrow observed in the behaviour of real complex systems doesn’t have nowadays a fully satisfactory explanation. If one confides in the Laplace-dream that everything be exactly and completely describable by the known mechanical differential equations, the whole experimental evidence of the irreversibility of real complex processes can only be interpreted as an illusion due to the limits of human brain and shortness of human history. In this work it is (...) surmised that in the description of real events it would be more reasonable to renounce exactness and completeness of mechanical differential equations, assuming that also further effects exist in nature, governed by different kinds of rules, in spite of being so weak to be directly unobservable in single motions. This surmise can explain not only the time-arrow, but also why, in particular cases, it can happen that approximate and/or statistical models represent an improvement of mechanical theories instead of an approximation: this happened for Boltzmann gas-model and also for the famous work of Max Planck on blackbody-radiation. And it also appears as a more promising “working hypothesis”, stimulating and guiding us to learn more about limits and origin of the basic equations, and also about the nature of chance and the meaning of probability, which is nowadays not clear in spite of the fundamental role it plays in physics. Particularly that kind of probability which gives the connection between quantum–mechanical differential equations and observable events. (shrink)

In the De mineralibus, Albert the Great clearly states that minerals do not possess life, since – following the Aristotelian path – life is always connected with the operations of the soul. Nevertheless, dealing with the virtues of stones, Albert speaks about a curious difference between “living” and “dead” stones: living stones are substances that possess virtues caused by their forms, while non-living stones are called stones only equivocally because their virtues have expired. Moreover, throughout his work, Albert often seeks (...) help from the biological world to explain the nature and the processes of mineral substances: the coming-into-being of stones and metals is often compared to the generation of plants and animals; places where minerals are formed act as the mother’s womb for the embryo; sulphur and quicksilver are said to be the father and the mother of all metals; etc. The tendency to biologise inorganic nature is a key strategy that Albert uses to explain the processes and functions of the mineral world.

Im ‚Pfaffen Amis‘ des Strickers aus der ersten Hälfte des 13. Jahrhunderts finden sich äußerst eigenwillige Bildbeschreibungen, die in der Wort-Bild-Forschung wenig Beachtung erfahren haben. Dies liegt darin begründet, daß es sich um eine Schilderung nicht vorhandener bzw. imaginierter Bilder handelt. Es zeigt sich aber, dass gerade diese so unkonventionelle Ekphrase das mittelalterliche Repräsentations- und Imaginationsverständnis auf signifikante Weise thematisiert. Im vorliegenden Beitrag wird die Beschreibung dieser unsichtbaren imagines einerseits in den größeren Kontext des ‚Pfaffen Amis‘ gestellt und andererseits der (...) paradigmatische, metafiktionale Charakter dieses Textes für das mittelalterliche Repräsentations- und Fiktionsverständnis dargelegt. Hierzu wird die Ekphrase parallel zu mittelalterlichen gehirnanatomischen Texten und zur Zweikörperlehre von Ernst H. Kantorowicz gelesen. (shrink)

In the fluid cultural context of today, where the significance of sexual difference is continually diminished, if not completely denied , the encounter with the phenomenology of E. Stein and E. Levinas can be both stimulating and fruitful. Even though they have speculative perspectives that are very different and do not always reach the same conclusions, both authors agree that sexual difference and paternity and maternity connected with it, is not exclusively biological but also anthropological and philosophical. This significant convergence (...) certainly has its origin in a common phenomenological inspiration, which continues to bear fruit, as witnessed by the recent work of J.-L. Marion and of a writer of a clearly feminist inspiration, such as F. Giardini. (shrink)

RESUMO: O presente artigo tem por objetivo investigar a recepção do Tratado Teológico-Político de Espinosa, bem como sua crítica da religião pelo Marquês de Sade, numa obra bastante peculiar e que desafia todas as tentativas de classificação: La Philosophie dans le Boudoir. Em seu "Quinto Diálogo", Sade insere um texto intitulado "Franceses, mais um esforço se quereis ser Republicanos". Através do emprego desse artifício metalinguístico - um livro dentro de um livro - a política é agora introduzida na alcova e (...) o leitor se dá conta de que a instrução de Eugénie não é meramente sexual, mas também uma educação filosófica e política. Por meio de sua crítica ao Cristianismo, na primeira seção do texto, Sade argumenta que a tirania e a superstição religiosa são âmbitos intimamente relacionados, e a teologia é um dos principais alicerces do poder político. ABSTRACT: This article aims to investigate the interpretation by the Marquis de Sade of Spinoza's Theological-Political Treatise. Sade's interpretation appears in a very peculiar work which defies all rigid attempts of classification: La Philosophie dans le Boudoir. In the "Fifth Dialogue", Sade inserts a pamphlet entitled "Yet another effort, Frenchmen, if you would become Republicans". Through the employment of a metalinguistic device - a book inside a book - politics is now introduced into the boudoir, and the reader becomes aware that Eugénie's education is not merely sexual, but also philosophical and political. Through his critique of Christianity in the first section of the pamphlet, Sade argues that tyranny and religious superstition are closely related and that theology is one of the main foundations of political power.

In the mid-14th century, Henry of Herford wrote the Catena aurea entium, a work of remarkable length and composed of ten books – in turn divided into ansae extending over some 5000 questions. The present study aims to analyse some aspects that the recent critical edition of Book VI of the Catena has brought to light: firstly, the dependence on Albert the Great’s De mineralibus and the compilative method used by Henry in the reworking of his sources; secondly, the main (...) philosophical, medical and encyclopedic sources that structure the treatise on minerals (in which metals are also included); and lastly, the author’s personal contribution, especially highlighting the use of vernacular terms and the recounting of personal experiences, which became useful means in explaining certain natural phenomena such as the formation of fossils or the production of images and seals.

The relation between the moral account of the capital vices and the philosophical analysis of the passions of the human soul undergoes an important turning point from the 11th century onwards during the recovery of medical knowledge in the medieval West. In this wave of fervour towards a physiological approach in the investigation of the nature of man, the vice of acedia - as described by the Christian moral tradition - and the melancholic temperament - the result of a millenary (...) reworking and technicalisation of medical knowledge - found a point of contact in the passion of sadness. If authors such as Albert the Great and Thomas Aquinas, following the Christian heritage, characterised acedia as an escalation of the passion of sadness, the medical tradition from Hippocrates and Galen to Avicenna and Constantine recognised sadness as one of the most distinctive manifestations of the melancholic temperament. The aim of this study is to demonstrate, by retracing some aspects of this interweaving of traditions after the year 1000, how Dante’s description of the sinners of acedia in Canto VII of the Inferno takes up the legacy of this hybridisation between the Christian description of acedia and the physiological description of melancholy.

This contribution focuses on some of the latest advances in Eckhart Studies concerning the German sermons, the edition of the Quaestiones Parisienses and the dating of the Opus tripartitum. Though not adressed by Josef Quint's edition, the the liturgical order of the German sermons has been gaining prominence, shading new light on their interpretation: in this respect, considering the order of the medieval Dominican liturgy enables to approach the communicative circumstances of the sermons doing justice to Eckhart's homiletic effort. Moreover, (...) four new Quaestiones Parisienses collected in the Codex Vaticanus latinus 1086 have been recently reconsidered, providing evidence about the attribution to the Dominican master. Lastly, due to the re-examination of the Cod. Amplon. F 181, the recent suggestions for backdating the Opus tripartitum reveal a different overview of Eckhart's intellectual activity. (shrink)
