The proof of the Second Incompleteness Theorem consists essentially of proving the uniqueness and explicit definability of the sentence asserting its own unprovability. This turns out to be a rather general phenomenon: Every instance of self-reference describable in the modal logic of the standard proof predicate obeys a similar uniqueness and explicit definability law. The efficient determination of the explicit definitions of formulae satisfying a given instance of self-reference reduces to a simple algebraic problem-that of solving the corresponding fixed-point equation (...) in the modal logic. We survey techniques for the efficient calculation of such fixed-points. (shrink)

In a recent paper, Montagna proved the undecidability of the first-order theory of diagonalisable algebras. This result is here refined — the set of finitely refutable sentences is shown effectively inseparable from the set of theorems. The proof is quite simple.

Background: Legislation on physician-assisted suicide is being considered in a number of states since the passage of the Oregon Death With Dignity Act in 1994. Opinion assessment surveys have historically assessed particular subsets of physicians.Objective: To determine variables predictive of physicians’ opinions on PAS in a rural state, Vermont, USA.Design: Cross-sectional mailing survey.Participants: 1052 physicians licensed by the state of Vermont.Results: Of the respondents, 38.2% believed PAS should be legalised, 16.0% believed it should be prohibited and 26.0% believed it should (...) not be legislated. 15.7% were undecided. Males were more likely than females to favour legalisation . Physicians who did not care for patients through the end of life were significantly more likely to favour legalisation of PAS than physicians who do care for patients with terminal illness . 30% of the respondents had experienced a request for assistance with suicide.Conclusions: Vermont physicians’ opinions on the legalisation of PAS is sharply polarised. Patient autonomy was a factor strongly associated with opinions in favour of legalisation, whereas the sanctity of the doctor–patient relationship was strongly associated with opinions in favour of not legislating PAS. Those in favour of making PAS illegal overwhelmingly cited moral and ethical beliefs as factors in their opinion. Although opinions on legalisation appear to be based on firmly held beliefs, approximately half of Vermont physicians who responded to the survey agree that there is a need for more education in palliative care and pain management.

This study examines the presence and roles of female directors of U.S. Fortune 500 firms, focusing on committee assignments and director background. Prior work from almost two decades ago concludes that there is a systematic bias against females in assignment to top board committees. Examining a recent data set with a logistic regression model that controls for director and firm characteristics, director resource-dependence roles and interaction between director gender and director characteristics, we find that female directors are less likely than (...) male directors to sit on executive committees and more likely than male directors to sit on public affairs committees. There is little if any evidence of systematic gender bias in director assignment to other board committees. We find some evidence that boards evaluate resource dependence differently for women than men. (shrink)

How do aboriginal traditional land rights fare in the face of modern business? “Belatedly, Australia is dealing with a major human rights issue it has attempted to sweep under the rug for 200 years”. The author is completing his MBA at London Business School and is a mining engineer of Australian origin.

The Internet is rapidly developing into an important medium of communication in modem society, and both psychological research and therapeutic interventions are being increasingly conducted using this new communication medium. As therapeutic interventions using the Internet are becoming more prevalent, it is becoming increasingly important to conduct research on psychotherapeutic Internet interventions to assist in the development of an appropriate standard of practice regarding interventions using this new medium. In this article, we examine the Internet and the current psychological uses (...) which are being initiated using this medium. Ethical concerns related to the psychological use of the Internet are discussed, and guidelines are proposed for the conduct of Internet intervention research. (shrink)

It has long been a commonly held belief among classicists that traditional Romans frowned upon male homosexuality and associated it with the influence of Greek culture. There have always been exceptions to this belief, but when Paul Veyne published the following remarks in his 1978 article ‘La famille et l'amour sous le hautempire romain’, his views were quite heterodox: Il est faux que l'amour ‘grec’ soit, à Rome, d'origine grecque: comme plus d'une société méditerranéenne de nos jours encore, Rome n'a (...) jamais opposé l'amour des femmes à celui des garçons: elle a opposé l'activité à la passivité; être actif, c'est être un mâle, quel que soit le sexe du partenaire passif.

This introductory textbook presents Christian philosophical and theological approaches to ethics. Combining their expertise in philosophy and theology, the authors explain the beliefs, values, and practices of various Christian ethical viewpoints, addressing biblical teachings as well as traditional ethical theories that contribute to informed moral decision-making. Each chapter begins with Words to Watch and includes a relevant case study on a vexing ethical issue, such as caring for the environment, human sexuality, abortion, capital punishment, war, and euthanasia. End-of-chapter reflection questions, (...) illustrations, and additional information tables are also included. (shrink)

Reappraising ideas associated with Ernst Bloch, Roland Barthes and Gaston Bachelard within the context of a utopian pedagogy, Hope, Utopia and Creativity in Higher Education reframes the transformative, creative and collaborative potential of education offering new concepts, tactics and pedagogical possibilities. Craig A. Hammond explores ways of analysing and democratising not only pedagogical conception, knowledge and delivery, but also the learning experience, and processes of negotiation and peer-assessment. Hammond shows how the incorporation of already existent learner hopes, daydreams, and (...) creative possibilities can open up new opportunities for thinking about popular culture and memory, learning and knowledge, and collaborative communities of support. Drawing together theoretical and cultural material in a teaching and learning environment of empowerment, Hammond illustrates that formative articulations of alternative, utopian futures, across sociological, humanities, and education studies subjects and curricula, becomes possible.

In his landmark monograph, "The Politics of Jesus", John Howard Yoder challenged mainstream Christian social ethics by arguing that the New Testament account of Jesus's founding of a messianic community entails a normative politics, not only for early Christianity but for the contemporary church. This challenge is further elaborated in several important posthumous publications, especially "Preface to Theology", in which Yoder examines the development of early Christology with attention to its political and ethical implications, and "The Jewish-Christian Schism Revisited", Yoder's (...) proposal for a renewed Jewish-Christian dialogue around the moral meaning of messianism. This article interprets these writings with reference to a range of critical scholarship on and about Yoder, Yoder and Augustine, and Jewish and Christian messianism, paying particular attention to questions of political ethics.

This article examines the anonymous progymnasmata in John Doxapatres' commentary on Aphthonius' Progymnasmata for evidence about their authorship, origin, and relations to other progymnasmata. These exercises include three chreias, a refutation and confirmation of the myth of Ganymedes, an encomium and invective of Agamemnon, a comparison of the grapevine and olive tree, and an ethopoeia on the deposition of the emperor Michael V Kalaphates. In addition to providing a formal rhetorical analysis of the exercises, the article offers further support for (...) the view of R. F. Hock and E. N. O'Neil that Doxapatres did not compose these exercises and that they all derive from a single collection. In an appendix, it argues that George Pachymeres, in his comparison of the olive tree and grapevine, used the anonymous comparison in Doxapatres and not the four parallel exercises by Ps.-Nicolaus.

This paper is an analysis of John Caputo’s philosophical interpretation of ‘the event’ as a form of revelation with specific reference to political theology and in dialogue with the theological notion of ‘interruption’ by the fundamental theologian Lieven Boeve. Following Charles Taylor’s interpretation of the post-secular, the argument is that Boeve’s ‘radical hermeneutics of religion’ is more postmodern than Caputo because it presents religion as co-constituted with language, particularity, and contingency and grounded within the specificity of the Christian narrative.

In her book The Myth of Sacred Prostitution in Antiquity, Stephanie Budin compiles and analyses an impressive array of literary sources which describe, or have been interpreted as describing, several practices that modern scholars have collectively and variously called sacred, ritual, cultic or temple prostitution. In general, as Budin explains, ‘[s]acred prostitution is the sale of a person's body for sexual purposes where some portion of the money or goods received for this transaction belongs to a deity … usually Aphrodite’. (...) Three major subtypes include ‘once-in-a-lifetime prostitution and/or sale of virginity in honor of a goddess’, activity that ‘involves women who are professional prostitutes and who are owned by a deity or a deity's sanctuary’, and ‘a temporary type of sacred prostitution, where the women are either prostitutes for a limited period of time before being married, or only prostitute themselves during certain rituals’.

The present study explores in what ways the name of Jesus was invoked by Pagans, Jews, and Christians. It is shown that in contrast to famous worthies of the past, such as Solomon and the patriarchs, whose reputations grew over the centuries, the name of Jesus was invoked during his public ministry and continued for centuries following the Easter proclamation. Besides important texts, the artifactual evidence is also examined.

This symposium provides five case studies of the ways that John Dewey's philosophy and practice were influenced by women or "weirdoes" (our choices include F. M. Alexander, Albert Barnes, Helen Bradford Thompson, Elsie Ripley Clapp, and Jane Addams) and presents some conclusions about the value of dialoging across difference for philosophers and other scholars.
