Neo-classical liberals aim to offer a more consistent, coherent, and morally ambitious form of liberalism than the traditional classical and social liberal alternatives by providing grounds for a strong commitment to both individual economic liberty and social justice. The key neo-classical liberal claim is that the stringent protection of negative economic liberty does not conflict with, but is rather an essential component of, a commitment to political and social justice. My focus in this article is not on this key neo-classical (...) claim itself, but rather on the conceptually prior question of the meaning and institutional implications of the negative conception of individual economic liberty. In addressing this question I trace some lines of argument which derive from the classical political economy of the late eighteenth and early nineteenth centuries. Drawing in particular on ideas and arguments developed by the American economist and social critic Henry George, I argue that a fully coherent and defensible conception of negative economic liberty is compatible with a commitment to a strongly conditional form of private landownership, but is incompatible with a commitment to absolute private property in land.

That two-way response to the Word of God neatly summarizes William Hill's witness to us as theologian as well: to he the mediator between classical and contemporary idiomata in such a way as to enrich the deliverances of both, reminiscent of Matthew's commendation of the " disciple in the kingdom of Heaven [being] like a householder who brings out from (...) his storeroom new things as well as old" (13 :52). The excitement of this project will not he lost on students of theology confronted with novel theories periodically renewed. What makes William Hill a theologians' theologian is not only his conceptual clarity, hut his capacity to move among us as a fellow inquirer. Bereft of any need to kill off contenders to make room for his innovations, we rather find him recalling on every page how much he has learned from others and wishes to pass on to us. University of Notre Dame Notre Dame, Indiana DAVID B. BURRELL, c.s.c. The Diversity of Religions: A Christian Perspective. By J. A. D1NoIA, O.P. Washington, D.C.: The Catholic University of America Press, 1992. $29.95 (cloth), $17.95 (paper). For some time now the debate in the Christian theology of religions has centered around the question of ·the possibility of salvation for nonChristians. The answers to this question have often been placed in a threefold typology: exclusivism, inclusivism or pluralism. Exclusivists generally maintain that salvation is conditional on an explicit confession of faith in Jesus Christ, hence non-Christians are lost. Pluralists, on the other hand, maintain that salvation can he found in different religions in various ways, and that Christianity is one among many paths to the divine reality. Inclusivists agree that non-Christians may he saved, and if they are it may he through rather than despite their religion. Inclusivists differ from pluralists in believing that Christ is the constitutive cause of all salvation, even therefore the salvation of a non-Christian. DiNoia's hook claims to do two very significant things. First, to go beyond the three approaches and suggest a fresh way of dealing with the question. Second, in doing so, to create a new agenda for the Christian theology of religions. My verdict: he partly fails and partly succeeds, and both his failings and success are deeply instructive and profoundly illuminating. DiNoia's argument is advanced carefully and lucidly and is acces- BOOK REVIEWS 525 sihle to non-specialists. The bibliographic essay/notes related to each chapter indicate thorough research (with one exception) and are a pleasure to read. DiNoia (a Thomist with Barthian leanings) closely follows George Lindbeck's cultural-linguistic model of religion, arguing that the specific way of life, determined by the actual doctrines held, uniquely shapes and moulds the religious practitioner. The goal and means of the religious way are intrinsically related and cannot he separated. He then persuasively argues that the difficulty with pluralists and inclusivists is that they impose a soteriocentricism upon other religions where there may he none! In contrast, DiNoia maintains one cannot say anything about the meaning of another religion apart from specific and proper attention to the ways in which its doctrines regulate its practice and stipulate the goal to he achieved by that way of life. In Christianity, eternal fellowship with the blessed Trinity can be said to he the goal (salvation) which is carefully orchestrated in minute detail through the liturgical life of the community. To claim that other religions attain the same salvific goal is therefore problematic. DiNoia's argument creates a space for other religions to really disclose what they are about in their doctrines and practice, without a priori categorization, and this is to he welcomed. Hence, the necessity of dialogue as the proper location for disclosure of the "other". Dialogue thereby becomes central to a theology of religions. Only in this process can we ask the question as to whether and how these ways of life relate to Christianity. DiNoia allows for the possibility that doctrinal truth and good actions can he found in other religions, without compromising the cen· trality of the incarnation as constitutive... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Dogma and Ecumenism: Vatican II and Karl Barth's Ad Limina Apostolorum ed. by Matthew Levering, Bruce L. McCormack, and Thomas Joseph White, O.P.Gavin D'CostaDogma and Ecumenism: Vatican II and Karl Barth's Ad Limina Apostolorum edited by Matthew Levering, Bruce L. McCormack, and Thomas Joseph White, O.P. (Washington, DC: Catholic University Press of America Press, 2020), ix + 369 pp.In May 1966 Karl Barth visited Rome. He was (...) invited to reflect on the Second Vatican Council, to ask questions to leading curial figures, and peritus theologians, as well as Pope Paul VI. Barth's book Ad Limina Apostolorum: An Appraisal of Vatican II contains his questions and an account from Barth of his visit, along with some other important essays. It is still deeply challenging in its incisiveness, despite its brevity. I have always been struck by Barth's Marian criticisms that are so central to his viewpoint about divine agency and human cooperation. These give us an excellent insight into his ecclesiology. They represent the reasons for much of his questioning of various Roman Catholic positions on all sorts of matters. Eberhard Busch's diaries, while Barth's assistant during this period, form a fascinating complimentary account of the visit. These tell of the not-so-fruitful visit to Augustin Cardinal Bea and the great highpoint (for Barth) of his one-hour audience with Pope Paul VI. Barth was impressed by the Jesuits during his visit, but not so much by the Dominicans. He thought the latter had absorbed too many streams of liberal modernity. The two Dominicans participating in this book turn those tides. Indeed, all the authors could be located within the conserving wings of their ecclesial membership, which makes the volume all the stronger in raising serious unresolved disagreements and noting important common ground. It is testimony to Barth's enduring value that this volume seems so timely. The Barth Centre at Princeton and the Pontifical Faculty of the Dominican House in Washington were the sponsors of this collection.The volume is structured around five of the key documents commented on by Barth, with a Catholic and Reformed voice reflecting on both the particular document and Barth's input (with the exception of Francesca Aran Murphy, who deals with George Lindbeck rather than Barth), thereby simultaneously pushing forward the Catholic–Reformed engagement with the Council and with Barth. There is a preface with a penetrating introduction by Thomas Joseph White, O.P., and an irenic opening chapter by Matthew Levering on biblical renewal at Vatican II. Then follow the twin reflections on the five documents.First (and rightly so) comes the Dogmatic Constitution on Revelation, Dei Verbum. Katherine Sonderegger develops a nuanced reflection on the metaphor of Scripture as mirror of God (found in Dei Verbum), showing [End Page 971] a deep appreciation of currents within Dei Verbum that Barth had not detected, but which are more connective with his concerns and preoccupations. Lewis Ayres rather impishly takes what Barth saw as the main weakness of the text (its chapter 2: "Handing on Divine Revelation") and makes it the greatest strength. Ayers provides a deeply learned and original exploration of the concept of "tradition" as sacramental. In this duet, Barth comes out looking like he may have missed hearing the melodies while too closely studying the score.Then follow two profound essays on Lumen Gentium, the Dogmatic Constitution on the Church. Christoph Schwöbel builds up a strong Protestant case for the necessary visible ecclesial identity of the Church, thus showing a deep convergence without denying differences that remain. White, in a deeply insightful and probing essay, goes to the heart of the ecclesiological difference between Barth and Yves Congar (and some other key Catholics at the time): the relationship between uncreated divine agency and created human agency, especially within the context of the post-apostolic Church. White suggests that, without some stable ecclesial mediations, there can be no proper relationship envisaged between the transcendent causality of God operating in Christ and the created, active cooperative acts with this grace. While building up both a metaphysical and a theological case against Barth's criticisms... (shrink)

Historically, many Christians have understood God’s transcendence to imply God’s properties categorically differ from any created properties. For multiple historical figures, a problem arose for religious language: how can one talk of God at all if none of our predicates apply to God? What are we to make of creeds and Biblical passages that seem to predicate creaturely properties, such as goodness and wisdom, of God? Thomas Aquinas offered a solution: God is to be spoken of only through analogy (the (...) doctrine of analogy). Gavin Hyman argues Aquinas’s doctrine of analogy was neglected prior to the early-modern period and the neglect of analogy produced the conception of a god vulnerable to atheistic arguments. Contra Hyman, in this paper, I show early-modern atheism arose in a theological context in which there was an active debate concerning analogy. Peter Browne (1665–1735) and William King (1650–1729) offered two competing conceptions of analogical predication that were debated through the 19th century, with interlocutors such as the freethinker Anthony Collins (1676–1729), theologian/philosopher George Berkeley (1685–1753), and skeptic David Hume (1711–1776). Lastly, I discuss the 18th century debate over theological analogy as part of the background relevant to understanding Hume’s Dialogues Concerning Natural Religion. (shrink)

A number of observations have led researchers to postulate that, despite being replication‐defective, human endogenous retroviruses (HERVs) may have retained the potential to cause or contribute to disease. However, mechanisms of HERV pathogenicity might differ substantially from those of modern infectious retroviruses or of the infectious precursors of HERVs. Therefore, novel pathways of HERV involvement in disease pathogenesis should be investigated. Recent technological advances in sequencing and bioinformatics are making this task increasingly feasible. The accumulating knowledge of HERV biology may (...) also facilitate the definition and general acceptance of criteria that establish HERV pathogenicity. Here, we explore possible mechanisms whereby HERVs may cause disease and examine the evidence that either has been or should be obtained in order to decisively address the pathogenic potential of HERVs.

Alexander George’s lucid interpretation of Hume’s “Of Miracles” provides fresh insights into this provocative text, explaining the concepts and claims involved. He also shows why Hume’s argument fails to engage with committed religious thought and why philosophical argumentation so often proves ineffective in shaking people’s deeply held beliefs.

This piece offers a retrospective review of a plenary speech at the 1969 Annual Meeting of the American Public Health Association by the leading environmentalist of the Nixon administration, attorney and judge Russell Train. Train's talk, titled “Prescription for a Planet,” can be seen as an early argument for uniting environmental health and public health as the two main determinants of both individual and population health and for the inclusion of these fields in the then‐new field of “bioethics.”.

The practice of conducting research online is in its infancy. Consequently there is debate concerning the ethical implications of online data collection. We outline three approaches to online data collection and focus specifically on the issues of consent and anonymity of participants. We conclude that ethical issues raised when planning and implementing online data collection are no different to those raised by more traditional approaches to data collection.

We say that A≤LRB if every B-random set is A-random with respect to Martin–Löf randomness. We study this relation and its interactions with Turing reducibility, classes, hyperimmunity and other recursion theoretic notions.

The concept of ‘place’, and general references to ‘geographies of …’ are making gradual incursions into nursing literature. Although the idea of place in nursing is not new, this recent spatial turn seems to be influenced by the increasing profile of the discipline of health geography, and the broadening of its scope to incorporate smaller and more intimate spatial scales. A wider emphasis within the social sciences on place from a social and cultural perspective, and a wider turn to ‘place’ (...) across disciplines are probably equally important factors. This trend is raising some interesting questions for nurses, but at the same time contributes some confusion with regard to imputed meanings of ‘place’. While it is clear that most nurse clinicians and researchers certainly understand that place of care matters to their practices and patients, many diverse uses of ‘place’ are found within nursing literature, and contemporary understandings of the term ‘place’ within nursing are not immediately clear. It is in this context that this article plans to advance the discussion of place. More specifically, the aims of this paper are threefold: to critique ‘place’ as it appears in nursing literature, to explore the use of ‘place’ within health geography, whence notions of place and ‘geographies of’ have originated and, finally, to compare and contrast the use of ‘place’ in both disciplines. This critique intends to address a deficit in the literature, in this era of growing spatialization in nursing research. The specific questions of interest here are: ‘what is “place” in nursing?’ and ‘how do concepts of place in nursing compare to concepts of place in health geography?’. (shrink)

Not long before the change of Government in Britain in 1997, the then Heritage Secretary, Virginia Bottomley, made a speech in which she praised British contemporary art, describing it as the most exciting and innovatory in the world. Unexciting as it seemed, her observation was profoundly innovatory, indeed in its small way historic. To my knowledge no British Cabinet Minister, still less a Conservative, has ever given an official seal of approval to what is conventionally regarded as avant-garde art. The (...) Labour Government has echoed its predecessor's praise at a higher volume, as if determined to out-do it. The sanctification by the state of works of contemporary art has now become part of the discourse of officialdom. (shrink)

A Dedekind algebra is an ordered pair (B, h), where B is a non-empty set and h is a similarity transformation on B. Among the Dedekind algebras is the sequence of the positive integers. From a contemporary perspective, Dedekind established that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable. The purpose here is to show that this seemingly isolated result is a consequence of more general results in the model theory of second-order languages. (...) Each Dedekind algebra can be decomposed into a family of disjoint, countable subalgebras called the configurations of the algebra. There are ?0 isomorphism types of configurations. Each Dedekind algebra is associated with a cardinal-valued function on ? called its configuration signature. The configuration signature counts the number of configurations in each isomorphism type that occurs in the decomposition of the algebra. Two Dedekind algebras are isomorphic iff their configuration signatures are identical. The second-order theory of any countably infinite Dedekind algebra is categorical, and there are countably infinite Dedekind algebras whose second-order theories are not finitely axiomatizable. It is shown that there is a condition on configuration signatures necessary and sufficient for the second-order theory of a Dedekind algebra to be finitely axiomatizable. It follows that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable. (shrink)

The nineteenth century saw frequent appeals to the idea of a redeemer personality, a heroic leader – musings which culminated in the cults devoted to Hitler and Stalin. This article shows that the self-assertion of leaders can stimulate the self-abasement of the followers on whom they depend (and vice versa), and discusses in what circumstances such an interplay becomes dominant in a society, and with what advantages and disadvantages for it.

While a number of empirical studies have appeared on impaired self-awareness (ISA) after traumatic brain injury (TBI) over the last 20 years, the relative role of denial (as a psychological method of coping) has typically not been addressed in these studies. We propose that this failure has limited our understanding of how ISA and denial differentially affect efforts to rehabilitate persons with TBI. In this selective review paper, we summarize early findings in the field and integrate those findings with more (...) recent observations (i.e., 1999–2019). We believe that this synthesis of information and expert clinical opinion will inform future research on ISA and denial as well as approaches to rehabilitation for persons with TBI. (shrink)
