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

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 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)

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.

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)

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.

In this volume specialists of medieval music and philosophy put the medieval 'musica' into the context of ideas and institutions in which it existed. The significance of 'musica' cannot be understood from a modern point of view since 'music' does not match the medieval 'musica'.

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

While the turn to vulnerability in law responds to a recurrent critique by feminist scholars on the disembodiment of legal personhood, this article suggests that the mobilization of vulnerability in the criminal courts does not necessarily offer female drug mules a direct path to justice. Through an analysis of sentencing appeals of female drug mules in England and Wales, this article presents a feminist critique of the dispositif of the person and its relation to vulnerability. Discourses on drug mules’ vulnerability (...) mobilize the trope of the colonial victim in need of protection, which is often translated into legal mercy. But mercy is rather an expression of biopower which inscribes not only fragility onto the bodies of drug mules by figuring them as exemplar paradigms of colonial subjectivity, but also reinvigorates the dispositif of gender implicit in the legal person. In this set-up, it would appear as if law and politics totalize the registers of life, in this case the contours of vulnerable body. The article suggests we must revisit the image of the wounded body in order to carve out a space for resistance. Drawing on Elaine Scarry and Judith Butler, it suggests vulnerable bodies are marked by a semiotic openness, which renders them subject to appropriation but also able to signify the precarity produced by the law through their resistance to representation.
