This is the first full discussion of Philoponus' account of matter.

In this paper I propose a reading of Plotinus Enneads VI.1-3 [41-43] On the genera of being which regards this treatise as a coherent whole in which Aristotle's Categories is explored in a way that turns it into a decisive contribution to Plotinus' Platonic ontology. In addition, I claim that Porphyry's Isagoge and commentaries on the Categories start by adopting Plotinus' point of view, including his notion of genus, and proceed by explaining its consequences for a more detailed reading of (...) the Categories. After Plotinus' integration of the Categories into the Platonic frame of thought Porphyry saw the possibilities of exploiting the Peripatetic tradition both as a means to support the Platonic interpretation of the Categories and as a source for solutions to traditional questions. His allegiance to a division of being into ten, and his emphasis on semantics rather than ontology can be explained from this orientation. In the light of our investigation the alleged disagreement between Plotinus and Porphyry on the Categories changes its appearance completely. There are differences, but these can be best explained as confirmation and extension of Plotinus' perspective on the Categories and its role in Platonism. (shrink)

This volume collects Late Ancient, Byzantine and Medieval appropriations of Aristotle's Posterior Analytics, addressing the logic of inquiry, concept formation, the question whether metaphysics is a science, and the theory of demonstration.

In this paper I explore the ways in which Alexander of Aphrodisias employs and develops so-called ‘common notions’ as reliable starting points of deductive arguments. He combines contemporary developments in the Stoic and Epicurean use of common notions with Aristotelian dialectic, and axioms. This more comprehensive concept of common notions can be extracted from Alexander’s commentary on Metaphysics A 1–2. Alexander puts Aristotle’s claim that ‘all human beings by nature desire to know’ in a larger deductive framework, and adds weight (...) to Aristotle’s use of the common understanding of the notion of ‘wisdom’. Finally I will indicate how these upgraded common notions are meant to play an important role in the general framework of metaphysics as a science. (shrink)

Jaap Mansfeld and Frans de Haas bring together in this volume a distinguished international team of ancient philosophers, presenting a systematic, chapter-by-chapter study of one of the key texts in Aristotle's science and metaphysics: the first book of On Generation and Corruption. In GC I Aristotle provides a general outline of physical processes such as generation and corruption, alteration, and growth, and inquires into their differences. He also discusses physical notions such as contact, action and passion, and mixture. These (...) notions are fundamental to Aristotle's physics and cosmology, and more specifically to his theory of the four elements and their transformations. Moreover, references to GC elsewhere in the Aristotelian corpus show that in GC I Aristotle is doing heavy conceptual groundwork for more refined applications of these notions in, for example, the psychology of perception and thought, and the study of animal generation and corruption. Ultimately, biology is the goal of the series of enquiries in which GC I demands a position of its own immediately after the Physics. The contributors deal with questions of structure and text constitution and provide thought-provoking discussions of each chapter of GC I. New approaches to the issues of how to understand first matter, and how to evaluate Aristotle's notion of mixture are given ample space. Throughout, Aristotle's views of the theories of the Presocratics and Plato are shown to be crucial in understanding his argument. (shrink)

This collection of essays presents a novel interpretation of a signature work of Alexander of Aphrodisias, and of the Stoic philosophy he seeks to refute. It covers all chapters of the work, challenging existing scholarship in significant ways.

This is the first full discussion of Philoponus' account of matter. It is shown here that philosophical problems in Neoplatonism motivated the definition of prime matter as three-dimensional extension, and that Plotinus, Syrianus, and Proclus prepared the way for Philoponus.

This volume sheds new light on Alexander of Aphrodisias' On Mixture and Growth as an intelligent and carefully crafted rebuttal of Stoic blending, which Alexander regarded as the closest rival of his own brand of hylomorphism. The authors explore Alexander's dialectical method and determine the precise character of the Stoic theory he attacks. The problematic notions of mutual co-extension and infinite division appear in their proper context, while the successive stages of the process of blending are carefully distinguished from the (...) resulting state of the blend. In this perspective the discussion of growth that closes Alexander's work finds its natural place. (shrink)

La science étudie un système en évaluant ses grandeurs caractéristiques: elle définit ses dimensions. Combien de dimensions caractérisent le réel? Quelles dimensions sont les plus pertinentes? La physique classique étudie trois dimensions de l'espace et une de temps. Ces quatre dimensions sont réunies par la relativité restreinte et générale. Les théories cosmologiques les plus modernes en font intervenir de nouvelles, presque imperceptibles à l'homme. En mathématiques, le nombre de dimensions caractérisant un système peut être non entier. En biologie, on peut (...) s'interroger sur la dimension du système fondamental à étudier: la cellule, l'organe, l'individu? Comment la taille d'un organisme influe-t-elle sur son appréhension du réel? Enfin, en art pictural, comment représente-t-on les formes, la profondeur? De nouvelles questions fondamentales, une nouvelle approche pluridisciplinaire vous sont ici proposées. (shrink)

Waal shows how ethical behavior is as much a matter of evolution as any other trait.

Public debate on acceptable farm animal husbandry suffers from a confusion of tongues. To clarify positions of various stakeholder groups in their joint search for acceptable solutions, the concept of animal welfare was split up into three notions: no suffering, respect for intrinsic value, and non-appalling appearance of animals. This strategy was based on the hypothesis that multi-stakeholder solutions should be based on shared values rather than on compromises. The usefulness of such an artificial value distinction strategy was tested in (...) a small series of experiments. The results demonstrate that the chosen concept to distinguish between values is effective in a stakeholder context. Farmers’ views on doing good to animals appeared to be largely based on their value to prevent suffering and predominantly focused on the provision of regular care. Their priority for this value is clearly shared with other stakeholders, providing a basis for joint solutions. The concept of intrinsic value does not play a discernable role in farmers’ considerations. Based on the varying views on welfare, it can be inferred that there is a gradual rather than a principal difference between government legislation and farmers’ values, whereas public perception and acceptance of farm practices remains complicated. Distinction between value groups and focusing on a selected notion (such as no suffering) proved to be effective in bringing representatives of stakeholder groups together, but is unlikely to bridge the emotional gap between commercial farm practices and public ideals.

"It's the animal in us," we often hear when we've been bad. But why not when we're good? Primates and Philosophers tackles this question by exploring the biological foundations of one of humanity's most valued traits: morality. In this provocative book, primatologist Frans de Waal argues that modern-day evolutionary biology takes far too dim a view of the natural world, emphasizing our "selfish" genes. Science has thus exacerbated our reciprocal habits of blaming nature when we act badly and labeling (...) the good things we do as "humane." Seeking the origin of human morality not in evolution but in human culture, science insists that we are moral by choice, not by nature. Citing remarkable evidence based on his extensive research of primate behavior, de Waal attacks "Veneer Theory," which posits morality as a thin overlay on an otherwise nasty nature. He explains how we evolved from a long line of animals that care for the weak and build cooperation with reciprocal transactions. Drawing on both Darwin and recent scientific advances, de Waal demonstrates a strong continuity between human and animal behavior. In the process, he also probes issues such as anthropomorphism and human responsibilities toward animals. Based on the Tanner Lectures de Waal delivered at Princeton University's Center for Human Values in 2004, Primates and Philosophers includes responses by the philosophers Peter Singer, Christine M. Korsgaard, and Philip Kitcher and the science writer Robert Wright. They press de Waal to clarify the differences between humans and other animals, yielding a lively debate that will fascinate all those who wonder about the origins and reach of human goodness.

Não obstante as críticas de Giambattista Vico ao pensamento de Espinosa, é possível estabelecer uma relação de proximidade entre os dois. Se as críticas distanciam, o interesse histórico-filológico aproxima. Com efeito, para o estabelecimento de certa convergência entre os propósitos filosóficos dos dois autores, elencam-se os seguintes pressupostos: _i)_ tanto na _Ciência Nova_, quanto no _Tratado Teológico-Político_, a _filologia_ não é apenas conhecimento textual das línguas, porém via de acesso à história de um povo, pois guarda as mutações temporais da (...) vida civil e a memória do mundo de sentido no qual se gesta; _ii)_ a língua não é uma criação do rigor do entendimento, isto é, não é criação dos filósofos, mas da imaginação, portanto do _vulgo_. Desse modo, toda via de acesso ao conhecimento do passado passa inevitavelmente pela potência da _imaginação-fantasia_: questão que interpela Espinosa na _história dos hebreus_ e Vico na _natureza comum das nações_.

As a continuation of our studies regarding the use of rhetoric in the thought of Thomas Hobbes, the present study deals with the relation between eloquence, passions and rebellion in The Elements of Law, Natural and Politic. Thus, it is explained how the leaders of sedition and rebellion are necessarily, according to Hobbes, “eloquent men”. The aim is not only to separate the rhetorical tradition from the foundation of political sciences, but also to point out the supposed damages caused by (...) orators in civil life. Therefore, the conflicting and often contradictory relation between demonstration and persuasion in the politics of the 17th century is questioned, as well as the binding and constitutive role of passions.

The first part of this work starts with a passage of Machiavelli to show that the defense of a certain“realism” in the constitution of political philosophy does not excludeimagination. The defense of the efective truth of things against the imaginedrepublics has as an effect the affirmation that politics cannot operatewithout images: either the politician or the political thinker should notdisregard the imagination. Therefore, the importance of an attentivelook on what is inherent to imagination: the ability to create images. Inthis sense, (...) Hobbes appears as the heir of a tradition that unfolds in twothemes: his relation with the rhetorical tradition; the readers of Machiavelli. (shrink)

Depuis deux siecles, la Critique de la raison pure occupe une place centrale dans notre paysage philosophique. Deja du vivant de Kant, cette influence commence a s'exercer, et de maniere fulgurante. D'abord recue avec scepticisme, la premiere Critique suscite bientot l'enthousiames, au point de faire ecole, pour se voir ensuite sursumee par la jeune generation. Les etudes ici rassemblees temoignent de la diversite et de l'intensite de cette premiere reception, qui va de l'accusation d'idealisme dirigee contre la Critique, jusqu'au depassement (...) du criticisme dans l'idealisme allemand. A cet egard, la liste des auteurs traites dans le present recueil est eloquente: Garve, Feder, Hamann, Jacobi, Schultz, Eberhard, Enesideme-Schulze, Maimon, Reinhold, Hornemann, Fichte, Schelling, Baader, Hegel, Schleiermacher, W. von Humboldt et Bolzano.

Part 12: The fall of the house of ethics‘Sometimes a cliché is the best way to make ones point’From: Whatever works.For some seconds Gordon is blinded by the lights the television crews direct at him. More than 20 cameras focus on him, and one journalist yells “there he is!” Even Gordon is not used to that much attention, but vanity is a speedy advisor. Within seconds he has clad himself in the aura of important person, and knowledgeable ethicist, even if (...) he has no idea what that many journalists expect from him at precisely this moment. Particularly when he has little time, preparing for the world conference on bioethics in Singapore. Then a wave of disappointment hits the gathered gossip-mongering press. The floodlights are turned off, microphones are lowered, the buzzing quiets down.“Guys, this is not Testosterone Tony.”This Tony, the athlete who participated in the Olympic Games in Beijing, at that moment leaves the hospital by a back door, far away from the paparazzi. The armoured car of his sponsor Nanosock disappears from sight softly humming and brings him to a private clinic where he will be pampered and detoxified. His career in sports is over, but his reputation can certainly sell sports socks with nanofibres against sweaty feet. The only price he has to pay is to admit he has sweaty feet, not true, but a small price to pay considering the alternatives. In front of the hospital the disappointed and somewhat offended Gordon tries to save his ego and asks the journalists:“Maybe I can be of help? Do you want an ethical analysis of Testosterone Tony and enhancing evolution? My name is Gordon Mc….” Nobody listens, nobody reacts.A day later. Nurses Jake and Gwen return from the medication round. Jake looks at the unlit room in the Nuttree …. (shrink)

BackgroundThe emphasis on impact factors and the quantity of publications intensifies competition between researchers. This competition was traditionally considered an incentive to produce high-quality work, but there are unwanted side-effects of this competition like publication pressure. To measure the effect of publication pressure on researchers, the Publication Pressure Questionnaire (PPQ) was developed. Upon using the PPQ, some issues came to light that motivated a revision.MethodWe constructed two new subscales based on work stress models using the facet method. We administered the (...) revised PPQ (PPQr) to a convenience sample together with the Maslach Burnout Inventory (MBI) and the Work Design Questionnaire (WDQ). To assess which items best measured publication pressure, we carried out a principal component analysis (PCA). Reliability was sufficient when Cronbach’s alpha > 0.7. Finally, we administered the PPQr in a larger, independent sample of researchers to check the reliability of the revised version.ResultsThree components were identified as ‘stress’, ‘attitude’, and ‘resources’. We selected 3 × 6 = 18 items with high loadings in the three-component solution. Based on the convenience sample, Cronbach’s alphas were 0.83 for stress, 0.80 for attitude, and 0.76 for resources. We checked the validity of the PPQr by inspecting the correlations with the MBI and the WDQ. Stress correlated 0.62 with MBI’s emotional exhaustion. Resources correlated 0.50 with relevant WDQ subscales. To assess the internal structure of the PPQr in the independent reliability sample, we conducted the principal component analysis. The three-component solution explains 50% of the variance. Cronbach’s alphas were 0.80, 0.78, and 0.75 for stress, attitude, and resources, respectively.ConclusionWe conclude that the PPQr is a valid and reliable instrument to measure publication pressure in academic researchers from all disciplinary fields. The PPQr strongly relates to burnout and could also be beneficial for policy makers and research institutions to assess the degree of publication pressure in their institute. (shrink)

The notion of a migration system is often invoked but it is rarely clearly defined or conceptualized. De Haas recently provided a powerful critique of the current literature highlighting some important flaws that recur through it. In particular, migration systems tend to be identified as fully formed entities, and there is no theorization as to how they come into being and how they break down. The internal dynamics which drive such changes are not examined. Such critiques of migration systems relate (...) to wider critiques of the concept of systems in the broader social science literature, where they are often presented as black boxes in which human agency is largely excluded. The challenge is how to theorize system dynamics in which the actions of people at one time contribute to the emergence of systemic linkages at a later time. This article focuses on the genesis of migration systems and the notion of pioneer migration. It draws attention both to the role of particular individuals, the pioneers, and also the more general activity of pioneering which is undertaken by many migrants. By disentangling different aspects of agency, it is possible to develop hypotheses about how the emergence of migrations systems is related to the nature of the agency exercised by different pioneers or pioneering activities in different contexts.
