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.

As debate over the manipulation of human genes rages in the public sphere, James Peterson offers an informed Christian defense of genetic intervention. In Changing Human Nature he pointedly reminds us that the question we need most to consider is not whether our genes will undergo change but whether we will be conscious of and conscientious about the direction of that change. Drawing from the biblical tradition, Peterson argues that human beings have a unique capacity and calling to tend and develop the natural world - including themselves, their bodies, and their genes - as God's garden. While carefully addressing legitimate religious concerns, Peterson's theologically grounded yet jargon-free discussion puts forth clear and specific guidelines for the proper use of genetic intervention to help people. Distinctive for its nuanced approach, Changing Human Nature will fill the need for a thoughtful, positive Christian perspective on this timely topic. Book jacket.

What does 'autonomy' mean from a Christian perspective? What could a Christian environmental ethics bring to the debate about genetically modified food? This book investigates conflicting claims in the public realm about food biotechnology. It critically evaluates the contribution such technologies make to sustainable agricultural production and environmental stewardship. Challenging the received wisdom in popular environmental theology, the book defends the role of the human person as steward of creation and presents a human-centred Christian environmental ethics rooted in the Kantian tradition of moral philosophy. From this vantage point the author critiques the partiality of many contemporary environmental theologies, which argue for a return to the technological simplicity of an idealised past, or emphasise virtue while taking little account of the role that institutional issues play in framing and defining policy and good practice. In this context the author examines whether or not, under current conditions, transgenic food can contribute to sustainable agricultural production.

While most people throughout history have believed that we are both physical and spiritual beings, the rise of science has called into question the existence of the soul. Many now argue that neurophysiology demonstrates the radical dependence, indeed, identity, between mind and brain. Advances in genetics and in mapping human DNA, some say, show there is no need for the hypothesis of body-soul dualism. Even many Christian intellectuals have come to view the soul as a false Greek concept that is outdated and unbiblical. Concurrent with the demise of dualism has been the rise of advanced medical technologies that have brought to the fore difficult issues at both edges of life. Central to questions about abortion, fetal research, reproductive techologies, cloning and euthanasia is our understanding of the nature of human personhood, the reality of life after death and the value of ethical or religious knowledge as compared to scientific knowledge. In this careful treatment, J. P. Moreland and Scott B. Rae argue that the rise of these problems alongside the demise of Christian dualism is no coincidence. They therefore employ a theological realism to meet these pressing issues, and to present a reasonable and biblical depiction of human nature as it impinges upon critical ethical concerns. This vigorous philosophical and ethical defense of human nature as body and soul, regardless of whether one agrees or disagrees, will be for all a touchstone for debate and discussion for years to come.

In the immediate future we are likely to witness significant developments in human genetic science. It is therefore of critical importance that Christian ethics engages with the genetics debate, since it affects not just the way we perceive ourselves and the natural world, but also has wider implications for our society. This book considers ethical issues arising out of specific practices in human genetics, including genetic screening, gene patenting, gene therapy, genetic counselling as well as feminist concerns. Genetics and Christian Ethics argues for a particular theo-ethical approach that derives from a modified version of virtue ethics, drawing particularly on a Thomistic understanding of the virtues, especially prudence or practical wisdom and justice. The book demonstrates that a theological voice is highly relevant to contested ethical debates about genetics.

"We face unprecedented choices in genetics for which traditional ethics provides little direct guidance. What role can the religious community play in addressing the ethical and theological issues that even scientists now acknowledge as urgent?"--cover.

The development of biotechnology has produced nothing short of a revolution, both in our capacity to manipulate living things from single plant cells to human nature itself, but also to manufacture brand new life forms. This power to shape and create forms of life has sometimes been described as the power to "play God" and this book is about the ethics of "playing God" in the field of biotechnology. International scholars cover moral dilemmas posed by biotechnology, from the smallest cells through animals to the engineering of human beings.
