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'.

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.

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.

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.

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)

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)

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.

When the COVID-19 surge hit New York City hospitals, the Division of Medical Ethics at Weill Cornell Medical College, and our affiliated ethics consultation services, faced waves of ethical issues sweeping forward with intensity and urgency. In this article, we describe our experience over an eight-week period (16 March through 10 May 2020), and describe three types of services: clinical ethics consultation (CEC); service practice communications/interventions (SPCI); and organizational ethics advisement (OEA). We tell this narrative through the prism of time, (...) describing the evolution of ethical issues and trends as the pandemic unfolded. We delineate three phases: anticipation and preparation, crisis management, and reflection and adjustment. The first phase focused predominantly on ways to address impending resource shortages and to plan for remote ethics consultation, and CECs focused on code status discussions with surrogates. The second phase was characterized by the dramatic convergence of a rapid increase in the number of critically ill patients, a growing scarcity of resources, and the reassignment/ redeployment of staff outside their specialty areas. The third phase was characterized by the recognition that while the worst of the crisis was waning, its medium- and long-term consequences continued to pose immense challenges. We note that there were times during the crisis that serving in the role of clinical ethics consultant created a sense of dis-ease as novel as the coronavirus itself. In retrospect we learned that our activities far exceeded the familiar terrain of clinical ethics consultation and extended into other spheres of organizational life in novel ways that were unanticipated before this pandemic. To that end, we defined and categorized a middle level of ethics consultation, which we have termed service practice communication intervention (SPCI). This is an underappreciated dimension of the work that ethics consult services are capable of in times of crisis. We believe that the pandemic has revealed the many enduring ways that ethics consultation services can more robustly contribute to the ethical life of their institutions moving forward. (shrink)

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)

The past 50 years have seen an accumulation of evidence suggesting that associative learning depends on high-level cognitive processes that give rise to propositional knowledge. Yet, many learning theorists maintain a belief in a learning mechanism in which links between mental representations are formed automatically. We characterize and highlight the differences between the propositional and link approaches, and review the relevant empirical evidence. We conclude that learning is the consequence of propositional reasoning processes that cooperate with the unconscious processes involved (...) in memory retrieval and perception. We argue that this new conceptual framework allows many of the important recent advances in associative learning research to be retained, but recast in a model that provides a firmer foundation for both immediate application and future research.

We first show that a theorem by Cartan that generalizes the Frobenius integrability theorem allows us (given certain conditions) to obtain noncurvature solutions for the differential Bianchi conditions and for higher-degree similar relations. We then prove that there is no algorithmic procedure to determine, for a reasonable restricted algebra of functions on spacetime, whether a given connection form satisfies the preceding conditions. A parallel result gives a version of Gödel's first incompleteness theorem within an (axiomatized) theory of gauge fields.

Health technology assessment (HTA) is often biased in the sense that it neglects relevant perspectives on the technology in question. To incorporate different perspectives in HTA, we should pursue agreement about what are relevant, plausible, and feasible research questions; interactive technology assessment (iTA) might be suitable for this goal. In this way a kind of procedural ethics is established. Currently, ethics too often is focussed on the application of general principles, which leaves a lot of confusion as to what really (...) is the matter in specific cases; in an iTA clashes of values should not be approached by use of such ethics. Instead, casuistry, as a tool used within the framework of iTA, should help to articulate and clarify what is the matter, as to make room for explication and consensus building. (shrink)
