The properties of belief revision operators are known to have an informal semantics which relates them to the axioms of conditional logic. The purpose of this paper is to make this connection precise via the model theory of conditional logic. A semantics for conditional logic is presented, which is expressed in terms of algebraic models constructed ultimately out of revision operators. In addition, it is shown that each algebraic model determines both a revision operator and a logic, that are related (...) by virtue of the stable Ramsey test. (shrink)

Recently, John Bell has proposed that a specific conditional logic, C, be considered as a serious candidate for formally representing and faithfully capturing various (possibly all) formalized notions of nonmonotonic inference. The purpose of the present paper is to develop evaluative criteria for critically assessing such claims. Inference patterns are described in terms of the presence or absence of residual classical monotonicity and intrinsic nonmonotonicity. The concept of a faithful representation is then developed for a formalism purported to encode (...) a pattern of nonmonotonic inference already captured by another. In the main body of the paper these evaluative criteria are applied to assess (negatively) whether C or any conditional logic provides a faithful representation for nonmonotonic patterns of inference captured by inference operators and relations modeling the dynamics of belief change.

We introduce two new belief revision axioms: partial monotonicity and consequence correctness. We show that partial monotonicity is consistent with but independent of the full set of axioms for a Gärdenfors belief revision sytem. In contrast to the Gärdenfors inconsistency results for certain monotonicity principles, we use partial monotonicity to inform a consistent formalization of the Ramsey test within a belief revision system extended by a conditional operator. We take this to be a technical dissolution of the well-known Gärdenfors dilemma.In (...) addition, we present the consequential correctness axiom as a new measure of minimal revision in terms of the deductive core of a proposition whose support we wish to excise. We survey several syntactic and semantic belief revision systems and evaluate them according to both the Gärdenfors axioms and our new axioms. Furthermore, our algebraic characterization of semantic revision systems provides a useful technical device for analysis and comparison, which we illustrate with several new proofs. (shrink)

In this article, we first review the development of clinical ethics in pediatrics in the United States. We report that, over the last 40 years, most children’s hospitals have ethics committees but that those committees are rarely consulted. We speculate that the reasons for the paucity of ethics consults might be because ethical dilemmas are aired in other venues. The role of the ethics consultant, then, might be to shape the institutional climate and create safe spaces for the discussion of (...) difficult and sometimes contentious issues. Finally, we report how pediatric clinical ethics has evolved differently in a number of other countries around the world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:What Has Chalcedon to Do with Lhasa? John Keenan’s and Lai Pai-chiu’s Reflections on Classical Christology and the Possible Shape of a Tibetan Theology of IncarnationThomas CattoiThe starting point of this paper is a critique of John Keenan’s so-called “Mahāyāna Christology” in The Meaning of Christ, in light of Lai Pai-chiu’s “Chinese” response to Keenan’s position. My argument is that Lai correctly construes the Chalcedonian definition as (...) a critique of Hellenist ontology, but fails to critique Keenan’s crucial contention that this same definition ratifies the subjugation of lived spiritual experience to abstract philosophical speculation. I also claim that Lai does not engage Keenan’s flawed use, in his constructive Christology, of the teaching of the Buddha-bodies, which in my opinion could provide an apposite template for the development of a Tibetan contextual Christology. My paper has a twofold purpose: on one hand, I sketch the contours of a possible Tibetan theology of incarnation; on the other hand, I offer a few methodological reflections on the role of classical doctrinal definitions in the development of new contextual theologies.The burden of this paper is to offer a few suggestions toward the formulation of a culturally contextual theology of incarnation, which uses the resources of Mahāyāna speculation on the embodiment of the Buddha. My starting point is Lai’s critique of Keenan’s well-known 1989 volume The Meaning of Christ, in which Keenan sets out to critique traditional Hellenist Chalcedonian Christology and argues for an alternative articulation of the hypostatic union based on the Mahāyāna teaching of the Buddha-bodies.1 Lai’s article revisits Keenan’s critique and argues that the Chalcedonian definition, far from canonizing the uncritical appropriation of a school of thought, evidences the profound limitations of philosophical discourse. Keenan’s underlying contention that traditional Christology subjects the Christian message to the strictures of alien categories is thus deconstructed, although Lai goes on to offer yet one more Christological synthesis based on the Chinese understanding of Buddha nature. In my paper I concur with Lai’s reading of Chalcedonian categories, which I regard [End Page 13] as more accurate and fruitful than Keenan’s, but I also argue that Lai fails to engage the totality of Keenan’s argument and therefore does not appreciate the deeper flaws in Keenan’s appropriation of the Buddhakāya teaching. My constructive suggestion toward the end of this paper is that such teaching could actually provide a most useful template for the development of a “Tibetan” theology of incarnation, which would remain in continuity with the Chalcedonian tradition, and yet resort to the linguistic and philosophical categories of the local culture.Theologians wishing to develop contextual articulations of Christian doctrine often meet considerable resistance, since their emphasis on the culturally contingent nature of traditional formulas is seen as a challenge to their continuing normative character. As early as 1969, Joseph Ratzinger’s Introduction to Christianity expressed serious reservations about the growing tendency to “de-Hellenize” Christian theology and strongly reasserted the enduring “providential” character of traditional Trinitarian and Christological formulas.2 At the same time, the development of a postcolonial Christianity in many Asian and African countries could not but call for inculturated expressions of the Christian faith that embedded the Christian message in the categories of the local culture. Theologian Stephen B. Bevans begins his work Models of Contextual Theology claiming that in the contemporary world, “the contextualization of [Christian] theology [...] is really a theological imperative.” 3 The understanding of theology as an objective and unchanging science of faith is thus superseded by a new approach that gives pride of place to the religious experience of the individual and the community where he or she lives, operates, and worships.4 Bevans’s call for a contextual theology views the “experience of the present” as the ultimately normative benchmark against which the “experience of the past” is assessed, in the search for a new synthesis rooted in a particular cultural and social location.5The development of new Christological formulas that use the resources of Asian Buddhist culture is thus possible only after the...

Em boa parte do Artigo 68 do Livro Primeiro de seu Estado e Pranto da Igreja, Álvaro Pais, O. Min. (c. 1270-1349) refuta 5 proposições com implicações políticas atribuídas a Marsílio de Pádua (1280-1342). Neste artigo, analisamos a refutação dessas proposições feitas pelo Menorita galego, comparando-as, de um lado, com os textos, efetivamente escritos pelo Médico paduano, que se encontram em sua obra Defensor da Paz (1324) e, de outro, cotejando-o com uma Epistula ad quosdam cardinales, de autoria do (...) mencionado Frade, escrita pelo menos dois anos antes. Desse estudo resultaram as seguintes conclusões: 1 – Frei Álvaro, sem fazer nenhuma alusão, apoiou-se basicamente na mencionada Epistula. 2 – Sob o aspecto doutrinal, essencialmente, não há diferença entre ambos os textos alvarinos. 3 – Nos dois textos, o Franciscano galego não compulsou o Defensor da Paz, tendo utilizado as teses que os censores dessa obra imputaram ao seu autor; em 1327, quando o Papa João XXII condenou-a como herética. PALAVRAS-CHAVE – Álvaro Pais. Marsílio de Pádua. Plenitude do poder. Filosofia política. ABSTRACT In a large part of the Article 68 of the Book one of his Status et Planctus Ecclesiae, Alvarus Pelagius O. Min. (c. 1270-1349) refutes five propositions, having political implications, attributed to Marsilius Patavinus (1280-1342). In this study, we analyze the refutation of these propositions made by Alvarus, comparing, on the one hand, with the texts, really, written by Marsilius, which are in his book entitled Defensor pacis (1324), and on the other hand, quoting Alvarus’ text with the Epistula ad quosdam cardinales, also written by the mentioned Franciscan friar two years before. From this study, resulted the following conclusions: 1 – Without to do any mention in the Article 68, the principal Alvarus’ source was the referred Epistula. 2 – Considering the two texts written by Fr. Alvarus, according the doctrinal aspect, they are essentially equal. 3 – In both texts we could see that Alvarus not had in his hands the Defensor Pacis, having used the thesis which the censors of this book imputed to Marsilius in 1327, when this book was condemned as heretic by the Pope John XXII. KEY WORDS – Alvarus Pelagius. Marsilius of Padua. Plentitude of power. Political philosophy. (shrink)

ABSTRACT This article proposes a reading of the novel O pai da menina morta [Dead Girl’s Father], by Tiago Ferro, linked to the theme of Christian resurrection materialized in the Gospel according to John. The biblical episodes about the resurrection of Lazarus and Jesus Christ are placed in dialogue with the narrative of the Brazilian author, as well as the symbolisms regarding the pelican and the celebration of Christian Easter, figures belonging to the structure of the work under examination. (...) The analyses put in discussion promote the understanding that Tiago Ferro, when indicating the religious discourse, refracts it to the constitution of his narrative voice, relocating it to the secular, profane level, typical of the human condition. The theoretical foundation working as a support for the reading of this work stands out in the contributions of the Circle of Mikhail Bakhtin, Frederico Lourenço, Northrop Frye, among others.

Este artigo apresenta um estudo sobre as conferências proferidas por John Dewey (1859-1952), na Universidade de Pequim, no ano de 1919. O interesse de pesquisa está em uma palestra, na coletânea de conferências, cujo tema versava sobre o socialismo. Portanto, procura-se analisar as intepretações elaboradas por Dewey a respeito do socialismo, suas recomendações sociais e políticas para a China naquele período revolucionário e, principalmente, suas apropriações e considerações no que concerne ao pensamento de Karl Marx (1819-1883). A influência das (...) ideias de Dewey na China, suas aprendizagens naquele país e o impacto do seu pensamento no movimento revolucionário também serão abordados na presente investigação. (shrink)

With precision and profundity born of 30 years of devoted study, John Boyle offers an essential introduction to St. Thomas Aquinas on Scripture, shedding helpful light on the goals, methods, and commitments that animate the Angelic Doctor's engagement with the sacred page. Because the genius of St. Thomas's approach to the Bible lies not so much in its novelty but rather in the fidelity and clarity with which he recapitulates the riches of the preceding interpretive Tradition, this initiation into (...) St. Thomas's vision of Scripture is itself an orientation to the Church's vision of Scripture, from the Fathers through and beyond the Middle Ages. St. Thomas's embeddedness within the Church's Tradition and his own historical context is integral to his approach to Scripture, yet it sets him at some distance from modern readers, for whom his interpretive vision may seem perplexing or even impenetrable. In this Primer, Boyle first provides an acclimation to this medieval context through a survey and explanation of pertinent technical terminology used by St. Thomas and characteristic of the scholastic theology of the time. With an eye to the medieval practice of considering Scripture according to the fourfold division of causes, Boyle builds on this initial foundation by exploring in turn St. Thomas's accounts of the end or use of Scripture (final cause), its divine and human authorship (efficient cause), its order and division (material cause), and its literary styles or genres (formal cause). Drawing on writings from across St. Thomas's corpus, but especially his work On the Commendation and Division of Sacred Scripture and the prologues to his biblical commentaries, Boyle masterfully elucidates both the hermeneutical principles and deep wisdom of the Angelic Doctor's approach to Scripture, imparting invaluable guidance not only for reading and understanding St. Thomas and other great masters of the Tradition, but also-and ultimately-for understanding Scripture in light of this Tradition and reading it with greater benefit and joy.

Outlining a wide range of international perspectives on patient safety and the law, this Research Handbook will appeal to academics and researchers specialising in health and medical law, human rights and healthcare regulation. It will also serve as a valuable resource for legal and medical practitioners alike, as well as clinicians and professionals working in healthcare governance. (shrink)

The notion of proof is central to mathematics yet it is one of the most difficult aspects of the subject to teach and master. In particular, undergraduate mathematics students often experience difficulties in understanding and constructing proofs. Understanding Mathematical Proof describes the nature of mathematical proof, explores the various techniques that mathematicians adopt to prove their results, and offers advice and strategies for constructing proofs. It will improve students’ ability to understand proofs and construct correct proofs of their own. The (...) first chapter of the text introduces the kind of reasoning that mathematicians use when writing their proofs and gives some example proofs to set the scene. The book then describes basic logic to enable an understanding of the structure of both individual mathematical statements and whole mathematical proofs. It also explains the notions of sets and functions and dissects several proofs with a view to exposing some of the underlying features common to most mathematical proofs. The remainder of the book delves further into different types of proof, including direct proof, proof using contrapositive, proof by contradiction, and mathematical induction. The authors also discuss existence and uniqueness proofs and the role of counter examples. (shrink)

Abraham Pais's Subtle Is the Lord was a publishing phenomenon: a mathematically sophisticated exposition of the science and the life of Albert Einstein that reached a huge audience and won an American Book Award. Reviewers hailed the book as "a monument to sound scholarship and graceful style", "an extraordinary biography of an extraordinary man", and "a fine book". In this groundbreaking new volume, Pais undertakes a history of the physics of matter and of physical forces since the discovery (...) of x-rays. The book attempts to relate not only what has happened over the last hundred years but why it happened the way it did, what it was like for those scientists involved, and how what at the time may have seemed a series of bizarre or unrelated events, now with hindsight emerges as a logical sequence of events. Pais, a noted physicist, was personally involved in many of the developments he describes, and thus Inward Bound, like his earlier book, is filled with unique insights into the world of big and small physics. Between 1895 and 1983, the period he covers, the smallest distances explored have shrunk a hundred millionfold, Pais notes. Along this incompletely traveled "road inward," scientists have established markers that later generations will rank among the principal monuments of the twentieth century. In alternating technical and nontechnical sections, this magisterial survey richly conveys what has been discovered about the constituents of matter, the laws to which they are subject, and the forces that act on them. But the advances have certainly not come smoothly. The book shows that these have been times of progress and stagnation, of order and chaos, of clarity and confusion, of belief and incredulity, of the conventional and the bizarre; also of revolutionaries and conservatives, of science by individuals and by consortia, of little gadgets and big machines, and of modest funds and big money. About the Author: Abraham Pais is Detlev W. Bronk Professor of Physics at the Rockefeller University. The author of the prizewinning biography of Einstein now undertakes a history of modern physics.

Theories of discourse bring to realism new ideas about how knowledge develops and how representations of reality are influenced. We gain an understanding of the conceptual aspect of social life and the processes by which meaning is produced. This collection reflects the growing interest realist critics have shown towards forms of discourse theory and deconstruction. The diverse range of contributions address such issues as the work of Derrida and deconstruction, discourse theory, Eurocentrism and poststructuralism. What unites all of the contributions (...) is a sense that it is essential to provide a realist alternative to the hitherto dominance of social constructionism, hermeneutics and postmodernism, over many of the issues discussed. By developing a realist perspective the different authors attempt to embed discourse within the structured nature of the reality of the world. Realism can situate language, discourse and ideology within context specific, or 'causally efficacious' circumstances. Realism can help to uncover issues of power, representation, and subjectivity and how discursive and other social practices produce real effects. This can help us understand the manner in which social structures are reproduced through various forms of ideology and discourse. And by knowing this, we can start to address questions concerning human emancipation and how the world is to be transformed. (shrink)

Ever since Copernicus, scientists have continually adjusted their view of human nature, moving it further and further from its ancient position at the center of Creation. But in recent years, a startling new concept has evolved that places it more firmly than ever in a special position. Known as the Anthropic Cosmological Principle, this collection of ideas holds that the existence of intelligent observers determines the fundamental structure of the Universe. In its most radical version, the Anthropic Principle asserts that (...) "intelligent information-processing must come into existence in the Universe, and once it comes into existence, it will never die out." This wide-ranging and detailed book explores the many ramifications of the Anthropic Cosmological Principle, covering the whole spectrum of human inquiry from Aristotle to Z bosons. Bringing a unique combination of skills and knowledge to the subject, John D. Barrow and Frank J. Tipler--two of the world's leading cosmologists--cover the definition and nature of life, the search for extraterrestrial intelligence, and the interpretation of the quantum theory in relation to the existence of observers. The book will be of vital interest to philosophers, theologians, mathematicians, scientists, and historians, as well as to anyone concerned with the connection between the vastness of the universe of stars and galaxies and the existence of life within it on a small planet out in the suburbs of the Milky Way.

For many years, the downtown in Clarksdale, with a municipal population of 17,960 and located in the northern part of the Mississippi Delta, had lost its role as the centre providing a wide range of jobs and services to those living in the surrounding region. For many cities and towns in America, downtown decline has been associated with the flight to the suburbs and the growth in shopping malls serving flourishing gated communities. In Clarksdale’s case, downtown decline has been due (...) largely to the advent of big box retailing and the location of new retail and commercial developments along the state highway on the edge of town, combined with the loss of jobs and population associated with agricultural restructuring. Today, however, Clarksdale has taken up the challenge to ‘revitalize’ the downtown in the face of economic adversity. Recovery is under way, and much of this is associated with blues music and Delta culture: Clarksdale is situated at the fabled ‘crossroads’ of Highways 49 and 61 and is also the home to national icons in literature, art and other cultural pursuits. These are key elements around which the downtown revitalization effort is focused. This paper charts the process by which the Clarksdale community has embarked on the road to downtown recovery, and highlights the town’s indelible links with the blues, borne out of years of toil, hardship and social deprivation. The paper emphasizes the importance of ‘champions’ and ‘creative people’, drawing on community support, in achieving downtown revitalization. Positive results are becoming evident with new businesses and jobs, improved levels of service, refurbishment of derelict buildings, a renewed sense of place, and an uplift in community confidence. The significance of cultural tourism to downtown revitalization is highlighted, with particular emphasis on the global appeal of blues, but with its roots firmly established in Clarksdale and the Delta.
