It is shown that the Riemannian curvature of the 3-dimensional hypersurfaces in space-time, described by the Wilson loop integral, can be represented by a quaternion quantum operator induced by the SU(2) gauge potential, thus providing a justification for quaternion quantum gravity at the Tev energy scale.

In this important study D. M. Armstrong offers a comprehensive system of analytical metaphysics that synthesises but also develops his thinking over the last twenty years. Armstrong's analysis, which acknowledges the 'logical atomism' of Russell and Wittgenstein, makes facts the fundamental constituents of the world, examining properties, relations, numbers, classes, possibility and necessity, dispositions, causes and laws. All these, it is argued, find their place and can be understood inside a scheme of states of affairs. This is a comprehensive and (...) rigorously this-worldly account of the most general features of reality, argued from a distinctive philosophical perspective, and it will appeal to a wide readership in analytical philosophy.

Truths are determined not by what we believe, but by the way the world is. Or so realists about truth believe. Philosophers call such theories correspondence theories of truth. Truthmaking theory, which now has many adherents among contemporary philosophers, is the most recent development of a realist theory of truth, and in this book D. M. Armstrong offers the first full-length study of this theory. He examines its applications to different sorts of truth, including contingent truths, modal truths, truths about (...) the past and the future, and mathematical truths. In a clear, even-handed and non-technical discussion he makes a compelling case for truthmaking and its importance in philosophy. His book marks a significant contribution to the debate and will be of interest to a wide range of readers working in analytical philosophy. (shrink)

We consider conditionals of the form A ⇒ B where A depends on the future and B on the present and past. We examine models for such conditional arising in Talmudic legal cases. We call such conditionals contrary to time conditionals.Three main aspects will be investigated: Inverse causality from future to past, where a future condition can influence a legal event in the past (this is a man made causality).Comparison with similar features in modern law.New types of temporal logics arising (...) from modelling the Talmudic examples. We shall see that we need a new temporal logic,which we call Talmudic temporal logic with linear open advancing future and parallel changing past, based on two parameters for time. (shrink)

Objective: The field of clinical ethics is relatively new and expanding. Best practices in clinical ethics against which one can benchmark performance have not been clearly articulated. The first step in developing benchmarks of clinical ethics services is to identify and understand current practices.Design and setting: Using a retrospective case study approach, the structure, activities, and resources of nine clinical ethics services in a large metropolitan centre are described, compared, and contrasted.Results: The data yielded a unique and detailed account of (...) the nature and scope of clinical ethics services across a spectrum of facilities. General themes emerged in four areas—variability, visibility, accountability, and complexity. There was a high degree of variability in the structures, activities, and resources across the clinical ethics services. Increasing visibility was identified as a significant challenge within organisations and externally. Although each service had a formal system for maintaining accountability and measuring performance, differences in the type, frequency, and content of reporting impacted service delivery. One of the most salient findings was the complexity inherent in the provision of clinical ethics services, which requires of clinical ethicists a broad and varied skill set and knowledge base. Benchmarks including the average number of consults/ethicist per year and the hospital beds/ethicist ratio are presented.Conclusion: The findings will be of interest to clinical ethicists locally, nationally, and internationally as they provide a preliminary framework from which further benchmarking measures and best practices in clinical ethics can be identified, developed, and evaluated.

To avoid misinterpretations one should substitute the ambiguous notion of 'new disease' with 'emerging disease'. A disease can be classified emergent in at least five dif férent historical situations; 1) it existed before it could be first identified but was overlooked from a médical point of view because it could not be conceptualized as a nosological entity; 2) it existed but was not noticed until a quantitative and/or qualitative change in its mani festations; 3) it did not exist in a (...) particular région of the world before its introduction from other régions; 4) it never existed in a human population but only in an animal population; 5) it is completely new - the triggering germ and/or necessary environmental conditions did not exist prior to the first clinical manifestations. A sériés of historical examples illustrate this classification. (shrink)

Citizens today are increasingly expected to be knowledgeable about and prepared to engage with biomedical knowledge. In this article, I wish to reframe this ‘public understanding of science’ project, and place fresh emphasis on public understandings of research: an engagement with the everyday laboratory practices of biomedicine and its associated ethics, rather than with specific scientific facts. This is not based on an assumption that non-scientists are ‘ignorant’ and are thus unable to ‘appropriately’ use or debate science; rather, it is (...) underpinned by an empirically-grounded observation that some individuals may be unfamiliar with certain specificities of particular modes of research and ethical frameworks, and, as a consequence, have their autonomy compromised when invited to participate in biomedical investigations. Drawing on the perspectives of participants in my own sociological research on the social and ethical dimensions of neuroscience, I argue that public understanding of biomedical research and its ethics should be developed both at the community level and within the research moment itself in order to enhance autonomy and promote more socially robust science. Public bioethics will have to play a key role in such an endeavour, and indeed will contribute in important ways to the opening up of new spaces of symmetrical engagement between bioethicists, scientists and wider publics—and hence to the democratisation of the bioethical enterprise.

LIFE offers various amusements, and anyone these days who can choose among them will come late to the study of hiatus in Greek prose. Germany in the 1880s, so it seems, was less fortunate, and few greater excitements were known to young or old than the hunt for hiatus; but now that we no longer strait-waistcoat our classical authors and the austerity of those times is discredited, few collectors of hiatus are to be found, and there are people even in (...) Germany who have never identified a single specimen. Yet there is nothing to be said for underrating an author' stylistic pretensions, still less for encouraging others to do the same; and the textual critic, whose path is slippery enough at the best of times, can ill afford to dispense with footholds. There has been no broad study of hiatus in Greek prose since 1841, when Benseler in a long and original book De hiatu in oratoribus et historicis Graecis went through the text of 27 authors and attempted to determine their practice.

While much has been written on the cultural and intellectual antecedents that gave rise to Carolus Linnaeus?s herbarium and his Systema Naturae, the tools that he used to transform his raw observations into nomenclatural terms and categories have been neglected. Focusing on the Philosophia Botanica, the popular classification handbook that he published in 1751, it can be shown that Linnaeus cleverly ordered and reordered the work by employing commonplacing techniques that had been part of print culture since the Renaissance. Indeed, (...) the functional adaptability of commonplace heads allowed him to split and combine the book?s chapters and tables and played a notable conceptual role in the way in which he spatialized words and, to a certain extent, specimens.

This book studies the interfaces of ethics, economics, and politics. Public policy issues involve all three of these subjects. Although it may be seen as suggesting the nucleus of a joint university course, the book is accessible to and should interest all those concerned with political decisions. Any such decision needs a criterion for judging whether one action or outcome is better than another. Even a dictator must to some extent be concerned about the economic welfare of the citizens; and (...) a democratic government more so. But how is a person's economic welfare to be judged? Furthermore, any political decision affects the economic welfare of different people differently. How then is the welfare of a community to be judged? This is an ethical question. Underlying any coherent public policy there must be a relevant moral code. (shrink)

M. I. Finley in his Politics in the Ancient World , 92–6 has recently cast doubt on the extent to which religious phenomena were taken seriously in ancient times. We believe that in stressing the reasons for scepticism he has overlooked much positive evidence for the impact of religious scruples on political behaviour and that in generalising he has undervalued the differences in this respect between ancient societies. The significance of some of this positive evidence is admittedly uncertain since in (...) civilian life scruples might be easy to observe without great suffering. The acid test is in time of war, so that is the concern of our present enquiry. That attitudes varied can be shown only by comparing societies. We have here limited our discussion to three for which the evidence is well preserved: the world of the Greek city before Alexander the Great, Rome before Constantine, and the Jews in the Hellenistic and Roman period. Elucidation of the reasons for their distinct attitudes would reveal much about each of these societies and its religious practices and conceptions, but there will be space here only to show that considerable variety did indeed exist. Most ancient peoples assumed that their gods approved of war; the pacifism of some pre-Constantinian Christians was exceptional. Nor did such rules in combat as were observed necessarily have a religious foundation. Ancient like modern scruples were often based on moral and humanitarian grounds, as in the treatment of corpses and civilians; the gods, as the guardians of general morality, might be involved in such matters, but only at a remove.

The Chairman of the Australian Law Reform Commission summarizes the discussion of in vitro fertilization (IVF) at the 1983 Mogul International Management Consultants Ltd. Conference on "Bioethics and Law of Human Conception in Vitro." Participants included IVF pioneers Patrick Steptoe and Robert Edwards, as well as other British physicians, scientists, sociologists, and moral philosophers. They raised questions about multiple embryo implantations, the risks and benefits of IVF, the ethical responsibilities of investigators, public policy and social control of IVF, threats to (...) the family and to genetic integrity, and the implications of IVF for determining criteria of personhood and the beginning of life.

In a previous paper by Pollock and Singh, it was proven that the total entropy of de Sitter space-time is equal to zero in the spatially flat case K=0. This result derives from the fundamental property of classical thermodynamics that temperature and volume are not necessarily independent variables in curved space-time, and can be shown to hold for all three spatial curvatures K=0,±1. Here, we extend this approach to Schwarzschild space-time, by constructing a non-vacuum interior space with line element ds (...) 2=e2λ(r) dt 2−e−2λ(r) dr 2−r 2(dθ 2+sin2 θdϕ 2), where $\mathrm{e}^{2{\lambda }(r)}=-\frac{1}{2}(1-\frac{r^{2}}{R_{0}^{2}})$ , which matches onto the vacuum exterior Schwarzschild metric in such a way that e2λ and d(e2λ )/dr are both continuous at the Schwarzschild radius R 0=2M. Then we show that the volume entropy is equal to A/4, where $A\equiv 4\pi R_{0}^{2}$ is the area of the apparent horizon, as found by Hawking. (shrink)

Legislation that authorises controversial organ procurement strategies but ignores respect for autonomy is flawed in principle and predictably unworkable in practiceThe UK Human Tissue Act 2004,1 designed to regulate all activity involving human tissue, organs, or bodies, was introduced in the House of Commons in December 2003, received Royal Assent on 15 November 2004,2 and has been partially implemented by Commencement Orders from April 2005. The new act, which repeals and replaces the Human Tissue Act 1961, the Anatomy Act 1984, (...) and the Human Organ Transplants Act 1989, has its origins in events of serious public concern, namely the retained organs scandals at Bristol Royal Infirmary3 and the Royal Liverpool Childrens’ Hospital.4 The act is correspondingly dominated by regulation of postmortem examinations and retention of human tissue, with consistent emphasis on the need for fully informed consent. Compliance with these requirements is now mandatory with the threat of up to three years’ imprisonment and/or fines for any deviation.The impact of the original proposals within the bill on research and the clinical practice of pathology have been carefully considered and documented,5 with subsequent amendments to ameliorate professional concerns.6 The act, however, also carries significant implications for medical practice in areas where donor recruitment for transplantation can take place, and representations on these aspects during readings of the bill7 have produced neither clarification, justification, nor amendment within the final legislation.Section 43 will make it lawful for hospital authorities “to take steps for the purpose of preserving the part for use for transplantation and to retain the body for that purpose”. The original explanatory notes for the bill8 while it proceeded through parliament implied that such action, prior to consent to transplantation being sought, was then lawful, clause 44 as section 43 ….

In lieu of an abstract, here is a brief excerpt of the content:Prolegomenon to the Homeric CentosM. D. UsherHomeric centos are poems made up entirely of verses lifted verbatim, or with only slight modification, from the Iliad and Odyssey. Only a few have survived antiquity. There exist three short Homeric centos in the Palatine Anthology (9.361, 381, 382; cf. Hunger 1978, 98–101), a ten–line cento about Herakles quoted by Irenaeus (Wilken 1967), and a seven– line cento grafitto inscribed on the (...) leg of a statue of Memnon in Egypt, which dates from the reign of Hadrian (Bernand 1960, 111–13; Bowie 1990, 65). There are also several cento–like incantations from the Greek Magical Papyri that use lines from Homer (Maltomini 1995). The only Homeric centos we possess in any quantity are the topic of this study. These originated with a Christian bishop named Patricius in the fourth century C.E., and were later expanded by Eudocia Athenaïs, wife of the emperor Theodosius II, in the early fifth.Eudocia's Homeric centos have long been neglected for lack of a complete and authoritative text. The responsibility for this situation rests with the otherwise eminent Homerist, Arthur Ludwich, whose Teubner edition of 1897, the only edition of the centos currently available, is based on a single, partially edited manuscript (Par. graec. suppl. 388: "Codex Mutinensis").1 Pessimism about establishing a reliable text and aesthetic disenchantment with the poem itself have hampered further study: according to Joseph Golega, for example, the Homeric centos are "weder des Druckes noch des Lesens wert" (Golega 1960, 1).Such an assessment lacks understanding and imagination. In his short study of 1979, Kurt Smolak called for a new edition of the centos in no uncertain terms, emphasizing the poem's great heuristic potential (49):Die Zentonen als spezielle Form der spätantiken Homerrezeption erwiesen sich als der Interpretation ihrer oft nicht anerkannten dichterischen Möglichkeiten durchaus zugänglich—dann sind sie doch wohl auch eine [End Page 305] Edition wert! Denn die frühbyzantinische Bibeldichtung kann dem Theologen, Komparatisten und sich auch dem Philologen ein wenig bebautes Arbeitsfeld eröffnen—sofern dieser sich nicht als Zensor im Namen einer klassizistischen Ästhetik versteht.The present study is offered as a prolegomenon to a new, complete edition of Eudocia's poem—a first installment on the larger interpretive program suggested by Smolak.2 It concerns my collation and transcription of a manuscript of the Homeric centos in the collection of the Iviron monastery on Mount Athos, Greece, which I inspected meis oculis in the summer of 1995.3 This hitherto unaccounted–for cento manuscript, datable on palaeographical grounds to the mid–fourteenth century, is one of a type used by Aldus Manutius for the editio princeps of the centos, published in Venice in 1502 (Renouard 1825, 57–62). Ludwich all but ignored Aldus' edition and the important revision of it published by Henricus Stephanus in 1578. His oversight was unfortunate, for the Iviron–Aldus–Stephanus recension of the centos (hereafter simply "Iviron," or "Iviron recension") is completely different from his, and as we shall see, better than his as well.Our investigation begins with the Aldine edition, the preface to which indicates that the text was transcribed and corrected for Aldus by Petrus Candidus, the son or perhaps nephew of Petrus Candidus Decembrius (1399–1477), papal secretary to Nicolas V. This younger Candidus belonged to the Benedictine order of the Camaldunensians, who were housed in the Venetian monastery of St. Michael Murianus. Following the preface of Candidus is a six–line elegiac poem on the centos composed by Scipio Fortiguerra, a member of the Aldine Academy who frequently collaborated with Aldus in preparing printed editions. We can safely infer, therefore, that both Candidus and Fortiguerra had a hand in the production of the editio princeps, and it is likely that the ms or mss they used were Venetian, or at least Italian (cf. Harris 1898, 25–26). That manuscript has yet to resurface, and may no longer exist, though it is possible that Iviron 4464 was once in Venice. The monastery obtained it, according to its librarian Father Theologos, from the personal library of [End Page 306] Maximos Margounios (1549–1602), bishop of Kythera, who... (shrink)
