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.

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.

Are theories ‘underdetermined by the evidence’ in any way that should worry the scientific realist? I argue that no convincing reason has been given for thinking so. A crucial distinction is drawn between data equivalence and empirical equivalence. Duhem showed that it is always possible to produce a data equivalent rival to any accepted scientific theory. But there is no reason to regard such a rival as equally well empirically supported and hence no threat to realism. Two theories are empirically (...) equivalent if they share all consequences expressed in purely observational vocabulary. This is a much stronger requirement than has hitherto been recognised— two such ‘rival’ theories must in fact agree on many claims that are clearly theoretical in nature. Given this, it is unclear how much of an impact on realism a demonstration that there is always an empirically equivalent ‘rival’ to any accepted theory would have—even if such a demonstration could be produced. Certainly in the case of the version of realism that I defend—structural realism—such a demonstration would have precisely no impact: two empirically equivalent theories are, according to structural realism, cognitively indistinguishable.

In his preface Mr Wilson writes 'I feel that a great many adults … would do better to spend less time in simply accepting the concepts of others uncritically, and more time in learning how to analyse concepts in general'. Mr Wilson starts by describing the techniques of conceptual analysis. He then gives examples of them in action by composing answers to specific questions and by criticism of quoted passages of argument. Chapter 3 sums up the importance of this kind (...) of mental activity. Chapter 4 presents selections for the reader to analyse, followed by questions of university entrance/scholarship type. This is a book to be worked through, in a sense a text-book. (shrink)

How do we acquire thoughts and beliefs about particulars by looking at pictures? One kind of reply essentially compares depiction to perception, holding that picture-perception is a form of remote object-perception. Lopes’s theory that pictures refer by demonstrative identification, and Walton’s transparency theory for photographs, constitute such remote acquaintance theories of depiction. The main purpose of this paper is to defend an alternative conception of pictures, on which they are not suitable for acquainting us with particulars but for acquainting us (...) with certain kinds of properties. This conception is outlined in §4, where it is argued that pictures are useful devices for what Heal has called indexical predication. In §2 and §3, I explain why I believe that remote acquaintance theories are false, and why picture-perception cannot function as a form of extended or remote object-perception. The main reason is that the contents of picture-perceptions do not themselves provide the kind of numerical and contextual information required for singular thought. Picture-reference is instead secured by independent beliefs or linguistic communication about the causal history of pictures as objects. In other words, it is beliefs about the numerical identity of pictures as objects that anchors the reference of the representational contents of pictures. (shrink)

In this philosophically sophisticated and historically significant work, John H. Zammito reconstructs Kant's composition of The Critique of Judgment and reveals that it underwent three major transformations before publication. He shows that Kant not only made his "cognitive" turn, expanding the project from a "Critique of Taste" to a Critique of Judgment but he also made an "ethical" turn. This "ethical" turn was provoked by controversies in German philosophical and religious culture, in particular the writings of Johann Herder and (...) the Sturm und Drang movement in art and science, as well as the related pantheism controversy. Such topicality made the Third Critique pivotal in creating a "Kantian" movement in the 1790s, leading directly to German Idealism and Romanticism. The austerity and grandeur of Kant's philosophical writings sometimes make it hard to recognize them as the products of a historical individual situated in the particular constellation of his time and society. Here Kant emerges as a concrete historical figure struggling to preserve the achievements of cosmopolitan Aufkl-rung against challenges in natural science, religion, and politics in the late 1780s. More specifically Zammito suggests that Kant's Third Critique was animated throughout by a fierce personal rivalry with Herder and by a strong commitment to traditional Christian ideas of God and human moral freedom. "A work of extraordinary erudition. Zammito's study is both comprehensive and novel, connecting Kant's work with the aesthetic and religious controversies of the late eighteenth century. He seems to have read everything. I know of no comparable historical study of Kant's Third Critique."-Arnulf Zweig, translator and editor of Kant's ;IPhilosophical Correspondence, 1759-1799;X "An intricate, subtle, and exciting explanation of how Kant's thinking developed and adjusted to new challenges over the decade from the first edition of the Critique of Pure Reason to the appearance of the Critique of Judgment. "--John W. Burbidge, Review of Metaphysics "There has been for a long time a serious gap in English commentary on Kant's Critique of Judgment Zammito's book finally fills it. All students and scholars of Kant will want to consult it."--Frederick Beiser, Times Literary Supplement. (shrink)

Obviously medicine should be evidence-based. The issues lie in the details: what exactly counts as evidence? Do certain kinds of evidence carry more weight than others? (And if so why?) And how exactly should medicine be based on evidence? When it comes to these details, the evidence-based medicine (EBM) movement has got itself into a mess – or so it will be argued. In order to start to resolve this mess, we need to go 'back to basics'; and that means (...) turning to the philosophy of science. The theory of evidence, or rather the logic of the interrelations between theory and evidence, has always been central to the philosophy of science – sometimes under the alias of the 'theory of confirmation'. When taken together with a little philosophical commonsense, this logic can help us move towards a position on evidence in medicine that is more sophisticated and defensible than anything that EBM has been able so far to supply.

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)

This book investigates the central role of reason in Islamic intellectual life. Despite widespread characterization of Islam as a system of belief based only on revelation, John Walbridge argues that rational methods, not fundamentalism, have characterized Islamic law, philosophy and education since the medieval period. His research demonstrates that this medieval Islamic rational tradition was opposed by both modernists and fundamentalists, resulting in a general collapse of traditional Islamic intellectual life and its replacement by more modern but far shallower (...) forms of thought. However, the resources of this Islamic scholarly tradition remain an integral part of the Islamic intellectual tradition and will prove vital to its revival. The future of Islam, Walbridge argues, will be marked by a return to rationalism"--Provided by publisher. (shrink)

Man controls and dominates the habitat of most animals, both domestic and wild and there is a need for a pragmatic, workable approach to the problem of reconciling animal welfare with economic forces and the needs of man. It is the author's contention that much of the current philosophical discussion of animal welfare is misdirected now that it is possible to measure to some extent what animals think and feel and how much they can appreciate their quality of life. The (...) book deals with farm animals, pets, wild animals and laboratory animals and dicusses their environmental requirements, fear and stress, their response to pain, injury, disease and death, behaviour and aggression, and the implications of biotechnology and genetic engineering. Finally, the book tries to reconcile reverence for life with the inescapability of killing and reviews the prospects of preserving and enhancing quality of life for animals through legislations, education, economic and moral incentives.

John Turri gives an example that he thinks refutes what he takes to be “G. E. Moore's view” that omissive assertions such as “It is raining but I do not believe that it is raining” are “inherently ‘absurd'”. This is that of Ellie, an eliminativist who makes such assertions. Turri thinks that these are perfectly reasonable and not even absurd. Nor does she seem irrational if the sincerity of her assertion requires her to believe its content. A commissive counterpart (...) of Ellie is Di, a dialetheist who asserts or believes that The Russell set includes itself but I believe that it is not the case that the Russell set includes itself. Since any adequate explanation of Moore's paradox must handle commissive assertions and beliefs as well as omissive ones, it must deal with Di as well as engage Ellie. I give such an explanation. I argue that neither Ellie's assertion nor her belief is irrational yet both are absurd. Likewise neither Di's assertion nor her belief is irrational yet in contrast neither is absurd. I conclude that not all Moore-paradoxical assertions or beliefs are irrational and that the syntax of Moore's examples is not sufficient for the absurdity found in them. (shrink)

A brief account of educational aims, focussing on preparation for a life of autonomous well-being.

I argue that incomprehensibility (what the ancient skeptics called acatalepsia) plays a central role in the skepticism of both Bayle and Hume. I challenge a commonly held view (recently argued by Todd Ryan) that Hume, unlike Bayle, does not present oppositions of reason--what Kant called antimonies.
