Does human nature possess normative significance? If so, what is it and what implications does it have for biotechnology? This essay critically examines three answers to these questions. One answer focuses on human nature as the ground of natural goods or goods dependent on human nature, another answer finds normative significance in the indeterminacy or malleability of human nature, and a third answer treats human nature as a natural sign of divine grace. Kathryn Tanner, who offers the second answer, and (...) Karl Barth, who offers the third, deny that nature has normative status in itself, apart from grace, but differ over the relation of grace to human nature as created. While indebted to Tanner, this essay favors Barth’s view as best suited to a Christian ethics of biotechnology. (shrink)

Theologies of human nature routinely reflect the insights of evolutionary biology, for which human biological nature is variable, changing and indeterminate in its boundaries with other living things. However, these theologies do not yet reflect what biotechnology discloses about human biological nature, namely, that it is malleable and indeterminate in its boundaries with machines. Does respect for human biological nature as created by God, or protection of the human person whose nature it is, require us to refrain from taking advantage (...) of its malleability and indeterminacy to select or design functions and traits? Or should we welcome malleability and indeterminacy as conditions for us to fulfill a vocation to determine our nature or bring it to perfection? And do malleability and indeterminacy render obsolete the notion that we look to our nature to determine what our good is? This article answers these questions. (shrink)

In public debates over biotechnology, theologians, philosophers, and political theorists have proposed that biotechnology could have significant implications for human nature. They argue that ethical evaluations of biotechnologies that might affect human nature must take these implications into account. In this book, Gerald McKenny examines these important yet controversial arguments, which have in turn been criticized by many moral philosophers and professional bioethicists. He argues that Christian ethics is, in principle, committed to some version of the claim that human nature (...) has normative status in relation to biotechnology. Showing how both criticisms and defences of this claim have often been facile, he identifies, develops, and critically evaluates three versions of the claim, and contributes a fourth, distinctively Christian version to the debate. Focusing on Christian ethics in conversation with secular ethics, McKenny's book is the first thorough analysis of a controversial contemporary issue. (shrink)

Once considered inimical to ethics, Karl Barth's theology is now rightly recognized for the central role ethics plays in it. But can Barth be safely placed in the mainstream tradition of Christian moral theology or does he offer a challenge to the latter? Gerald McKenny argues that the claim that God not only establishes the good from eternity but also brings it about in time is of fundamental importance to Barth's mature ethics. The good confronts us from the site of (...) its fulfilment in Jesus Christ, who has accomplished it in our place. The result is a vision of the moral life as a human analogy to God's grace, a vision which contrasts with the bourgeois vision of the moral life as an expression of human capability. Barth's moral theology is presented here as the attempt to reorder ethical thought and practice in light of this fundamental claim. This lucid and well-argued study is the most comprehensive treatment of Barth's ethics to date, offering a thorough account of the development of Barth's ethical thought and a wide-ranging analysis of its chief concepts and arguments. McKenny explains why certain widespread assumptions about Barth's moral theology are mistaken and explores the rich, complex, and often surprising ways in which Barth's position engages the traditions of Christian ethics and modern continental moral thought. Above all, McKenny shows why Barth's moral theology deserves our attention in spite of, or rather because of, its uneasy fit in the mainstream tradition of Christian moral theology. (shrink)

Preface Phillip R. Sloan, Gerald McKenny, Kathleen Eggleson pp. xiii-xviii In November of 2009, the University of Notre Dame hosted the conference “Darwin in the Twenty-First Century: Nature, Humanity, and God.‘ Sponsored primarily by the John J. Reilly Center for Science, Technology, and Values at Notre Dame, and the Science, Theology, and the Ontological Quest project within the Vatican Pontifical... 1. Introduction: Restructuring an Interdisciplinary Dialogue Phillip R. Sloan pp. 1-32 Almost exactly fifty years before the Notre Dame conference, the (...) world’s largest centenary commemoration of Darwin’s legacy was held at nearby University of Chicago. This event, organized by a committee spearheaded by University of Chicago anthropologist Sol Tax, drew nearly 2,500 registrants. In attendance were the primary leaders... Part 1. Nature 2. Evolution through Developmental Change: How Alterations in Development Cause Evolutionary Changes in Anatomy Scott F. Gilbert pp. 35-60 For the past half-century, the mechanisms of evolution have been explained by the fusion of genetics and evolutionary biology called “the Modern Synthesis.‘ The tenets of the Modern Synthesis have been generally formulated as such: 1. There is genetic variation within the population. 2. There is competition... 3. The Evolution of Evolutionary Mechanisms: A New Perspective Stuart A. Newman pp. 61-89 The Modern Evolutionary Synthesis, based on Charles Darwin’s concept of natural selection in conjunction with a genetic theory of inheritance in a population-based framework, has been, for more than six decades, the dominant scientific perspective for explaining the diversity of living organisms. In recent years, however, with the growth... 4. The Evolvability of Organic Forms: Possible, Likely, and Unlikely Change from the Perspective of Evolutionary Developmental Biology Alessandro Minelli pp. 90-115 Confronted with the extraordinary diversity of animal form, we can ask questions about function and adaptation. How does this animal move? How does it feed? How does it defend itself from its enemies? But we can also ask questions about development, reproduction, and heredity. What mechanisms produce these forms? How are these... 5. Accident, Adaptation, and Teleology in Aristotle and Darwinism David J. Depew pp. 116-143 Charles Darwin framed the Origin of Species to meet criteria for inductive science set out by John Herschel in his Preliminary Discourse on the Study of Natural Philosophy. Accordingly, he was distraught when he learned that Herschel, to whom he had sent a copy of his newly published book, was not... 6. The Game of Life Implies Both Teleonomy and Teleology Gennaro Auletta, Ivan Colagè, Paolo D’Ambrosio pp. 144-164 The present contribution is mainly aimed at suggesting the importance of teleonomy and teleology as explanatory mechanisms in biology in the light of recent achievements in the field, and at showing that they play an actual and relevant role in the realm of life. The issue of finality in biology still provokes lively debates in the... Part 2. Humanity 7. Humanity’s Origins Bernard Wood pp. 167-181 One of Charles Darwin’s many achievements is that he began the process of converting the Tree of Life from a religious metaphor into a biological reality. All types of living organisms, be they animals, plants, fungi, bacteria, or viruses, are at the end of twigs that reach the surface of the Tree of Life, and all the types of organisms... 8. Darwin’s Evolutionary Ethics: The Empirical and Normative Justifications Robert J. Richards pp. 182-200 In the increasingly secular atmosphere of the nineteenth century, intellectuals grew wary of the idea that nature had any moral authority. In an earlier age, one might have looked upon the dispositions of nature as divinely sanctioned, and thus one could call upon natural law to ground moral judgment. Certain behaviors, for instance, might have... 9. Crossing the Milvian Bridge: When Do Evolutionary Explanations of Belief Debunk Belief? Paul E. Griffiths, John S. Wilkins pp. 201-231 Two traditional targets for evolutionary skepticism are religion and morality. Evolutionary skeptical arguments against religious belief are continuous with earlier genetic arguments against religion, such as that implicit in David Hume’s Natural History of Religion. Evolutionary arguments are also... 10. Questioning the Zoological Gaze: Darwinian Epistemology and Anthropology Phillip R. Sloan pp. 232-266 This quotation from Darwin’s Descent of Man illuminates an under-explored issue in Darwin’s work---not the issue of evolutionary ethics itself, but the epistemology of experience assumed in his work, and the consequences of his application of this “zoological gaze‘ to human beings. I will term this epistemological stance in this chapter “natural historical... Part 3. God 11. Evolution and Catholic Faith John O’Callaghan pp. 269-298 To begin to examine the relation of orthodox Catholic Christian faith to evolutionary theory and the question of human origins, consider words of the fourth pope, St. Clement: Let us fix our gaze on the Father and Creator of the whole world, and let us hold on to his peace and blessings, his splendid and surpassing... 12. After Darwin, Aquinas: A Universe Created and Evolving William E. Carroll pp. 299-337 At the 2000 Jubilee Session for scientists, held at the Vatican in May of that year, Archbishop Józef Życiński offered an eloquent assessment of contemporary discourse on the relationship between the natural sciences and theology. He ended his address with the comment that what is needed today is a new Thomas Aquinas. I remember... 13. Evolutionary Theism and the Emergent Universe Józef Życiński pp. 338-354 The 150th anniversary of the publication of Charles Darwin’s The Origin of Species has been celebrated in the context of an animated debate concerning both scientific and philosophical issues implied by the theory of evolution.1 One finds a deep diversity of attitudes, both methodological and semantic, in the current debates on evolutionary... 14. Beyond Separation or Synthesis: Christ and Evolution as Theodrama Celia Deane-Drummond pp. 355-380 The fervor with which popular discourse on science and religion has continued to bubble up in the anniversary year celebrating Darwin’s achievements shows that the publically perceived conflict between science and religion will not go away. Academic discussion on such matters is therefore not just peripheral to cultural concerns but takes... Part 4. Past and Future Prospects 15. Imagining a World without Darwin Peter J. Bowler pp. 383-403 What would have happened if Charles Darwin had not lived to write On the Origin of Species?

Does theological ethics articulate moral norms with the assistance of moral philosophy? Or does it leave that task to moral philosophy alone while it describes a distinctively Christian way of acting or form of life? These questions lie at the very heart of theological ethics as a discipline. Karl Barth's theological ethics makes a strong case for the first alternative. Karl Barth's Moral Thought follows Barth's efforts to present God's grace as a moral norm in his treatments of divine commands, (...) moral reasoning, responsibility, and agency. It shows how Barth's conviction that grace is the norm of human action generates problems for his ethics at nearly every turn, as it involves a moral good that confronts human beings from outside rather than perfecting them as the kind of creature they are. Yet it defends Barth's insistence on the right of theology to articulate moral norms, and it shows how Barth may lead theological ethics to exercise that right in a more compelling way than he did.

The Ethical is a collection of readings on ethics and the nature of morality by some of the most important contemporary philosophers in the continental tradition. Presents penetrating discussions of the ethical as it is treated in Continental philosophy. Provides the foundation for further study of the continental treatment of ethical issues. Includes newly commissioned essays by prominent philosophers. Offers comparison between Continental and Anglo-American ethics.

The debate in this issue regarding the Roman Catholic condemnation of the morality of sterilization is puzzling for Protestants. As I will argue the puzzlement arises on two grounds. First, why would anyone object to direct sterilization for the cure or prevention of disease? Second, if one wanted to challenge such an objection on moral grounds why would one turn to medicine to do so? For Christian ethics there is nothing wrong in principle with direct sterilization when there are good (...) reasons for precluding the possibility of an additional pregnancy; and it is a serious theological mistake to treat medicine as an independent moral authority.

In Christian ethics the Gospel story of the encounter of a rich young ruler with Jesus has been interpreted in two major ways: one that treats Jesus’ directive to the ruler as a counsel that goes beyond the commandments the ruler claims to have kept, and another that treats the directive as contained in the commandments and exposing his failure to keep them. I reconstruct Calvin’s version of the second interpretation, contrast it with Aquinas’s version of the first, and point (...) out some problems with it. I then formulate a revised version that avoids the problems and amounts to a promising alternative for Christian ethics. (shrink)

Issues of genre and persuasion are central to ethical thought and practice. Until recently, there has been an asymmetry between religious ethics and moral philosophy in regard to these issues. Renewed attention to these issues in moral philosophy creates a new context for their consideration in religious ethics--one in which the relation of religious ethics and moral philosophy is less determinate than it has been in previous discussions. The four essays that comprise this Focus Section reflect this new context while (...) also making new contributions to perennial concerns of genre in ethical thought and practice. (shrink)

Most theoretical approaches in bioethics begin with a theory that articulates and defends basic principles or rules that are more or less systematically related and that seek to yield more or less precise conclusions with regard to specific acts, cases, or policies. Concerns about the agent and descriptions of the context of action stand on the margins of the theory. This is ironic, given the overwhelming importance and impact the training of health care professionals has upon them and upon the (...) practice of health care as a whole, and given the fact that many advocates of the theories themselves concede that one's beliefs and how one describes a situation and weighs "facts" and values relevant to the case strongly determine one's conclusions. While morality may not lead ineluctably to religion, as Kant believed, bioethics does appear inevitably to involve particularity. I examine the work of James M. Gustafson and Stanley Hauerwas to analyze two views of the role of particularity in bioethics. I then show the relevance of their work for addressing some problems with the practicality and concreteness of current models in bioethics.

A fundamental theme in Gilbert Meilaender’s work on bioethical issues is the relationship between the ethical claims of finitude and of freedom. This article identifies two ways in which Meilaender articulates this relationship and proposes a third way which avoids the limitations of the first two ways while serving Meilaender’s purpose, which is to redress what he sees as an imbalance in favor of the claims of freedom over those of finitude in contemporary biomedicine and bioethics. The article ends by (...) suggesting that Meilaender’s purpose would be best served by avoiding tensions between finitude and freedom as the third way does. (shrink)
