I adopt a cladistic view of species, and explore the possibility that there exists an equally valuable cladistic view of organismic traits. This suggestion seems to run counter to the stress on functional views of biological traits in recent work in philosophy and psychology. I show how the tension between these two views can be defused with a multilevel view of biological explanation. Despite the attractions of this compromise, I conclude that we must reject it, and adopt an essentially cladistic (...) conception of biological traits. (shrink)

Assuming it rational to treat other persons' probabilities as epistemically significant, how shall their judgements be weighted (Barnes [1998])? Several plausible methods exist, but theorems in classical psychometrics greatly reduce the importance of the problem. If scientists' judgements tend to be positively correlated, the difference between two randomly weighted composites shrinks as the number of judges rises. Since, for reasons such as representative coverage, minimizing bias, and avoiding elitism, we would rarely employ small numbers of judges (e.g. less than 10), (...) the difference between two weighting systems becomes negligible. Suggestions are made for quantifying verisimilitude, identifying 'types' of scientists or theories (taxometrics), inferring latent factors, and estimating reliability of pooled judgements. (shrink)

Digeser contends that our rich and varied practices of friendship multiply and moderate connections to politics. Along the way, she sets forth a series of ideals that appreciates friendship's many forms and its dynamic relationship to individuality, citizenship, political and legal institutions, and international relations.

The modal interpretation of quantum theory ascribes at each instant physical magnitudes with definite values to quantum systems. Starting from certain natural requirements, I determine unique solutions for the evolution of these possessed magnitudes in free systems and in special cases of interacting systems. The evolution is given in terms of transition probabilities that relate the values of the possessed magnitudes at one instant to the values at a second instant. I also determine a joint property ascription to a composite (...) system and its separate subsystems. Finally, I give a proof that the predictions of the modal interpretation with respect to measurement outcomes agree with the predictions of the standard interpretation. (shrink)

Rufus of Ephesus (fl.c.a.d.100) wrote a large body of works on a variety of medical topics. Generally speaking, the Arabic tradition is particularly important for the reconstruction of much of his œuvre. In the present article, I am going to present four new fragments of Rufus’On Melancholyand a fragment from an otherwise unknown monographOn Preferring Fresh Poppies. These new fragments provide fascinating new insights into Rufus’ approach to recording case histories.

The widely cited Nuffield Council on Bioethics ‘Intervention Ladder’ structurally embodies the assumption that personal autonomy is maximized by non-intervention. Consequently, the Intervention Ladder encourages an extreme ‘negative liberty’ view of autonomy. Yet there are several alternative accounts of autonomy that are both arguably superior as accounts of autonomy and better suited to the issues facing public health ethics. We propose to replace the one-sided ladder, which has any intervention coming at a cost to autonomy, with a two-sided ‘Balanced Intervention (...) Ladder,’ where intervention can either enhance or diminish autonomy. We show that not only the alternative, richer accounts of autonomy but even Mill’s classic version of negative liberty puts some interventions on the positive side of the ladder. (shrink)

In an earlier article I reported the text Ajax offered by the so-called ‘Roman’ family of Sophocles, the manuscripts G, R, and Q. My present purpose is to give collations of G, R, and Q for Philoctetes, with some introductory comments confined to this play; I hope I may be allowed to refer the reader to my previous article for a discussion of the general problems arising from a study of these manuscripts.

This volume ranges in time over a very long period and covers the Greeks' most original contributions to intellectual history. It begins and ends with philosophy, but it also includes major sections on historiography and oratory. Although each of these areas had functions which in the modern world would not be considered 'Literary', the ancients made a less sharp distinction between intellectual and artistic production, and the authors included in this volume are some of Europe's most powerful stylists: Plato, Herodotus, (...) Thucydides and Demosthenes. (shrink)

Professor Kamerbeek in a recent article raises some interesting questions about the value of the manuscript of Sophocles Parisinus gr. 2712, universally known as A. Ever since the time of Brunck, who was the first to use this manuscript extensively, it has been considered second only to Laurentianus XXXII 9 as a source of correct readings and as a witness of the old, i.e. pre-Byzantine, tradition of Sophocles. But the importance of A has been seriously challenged by Alexander Turyn, who (...) has sought to show that in Ajax, Electra, and Oedipus Tyrannus—the three plays which constitute the Byzantine Triad of Sophocles—A's text is principally that of the recension of Manuel Moschopulus —or, more strictly, the version of that recension which includes scholia by Maximus Planudes and some slight variations in the poetic text.
