B. Andrew Lustig, Baruch A. Brody, and Gerald P. McKenny Nearly every week the general public is treated to an announcement of another actual or potential "breakthrough" in biotechnology. Headlines trumpet advances in assisted reproduction, current or prospective experiments in cloning, and devel- ments in regenerative medicine, stem cell technologies, and tissue engineering. Scientific and popular accounts explore the perils and the possibilities of enhancing human capacities by computer-based, biomolecular, or mechanical means through advances in artificial intelligence, genetics, and nanotechnology. Reports abound concerning ever more sophisticated genetic techniques being introduced into ag- culture and animal husbandry, as well as efforts to enhance and protect biodiversity. Given the pace of such developments, many insightful commentators have proclaimed the 21st century as the "biotechnology century. " Despite a significant literature on the morality of these particular advances in biotechnology, deeper ethical analysis has often been lacking. Our preliminary review of that literature suggested that current discussions of normative issues in biotechnology have suffered from two major deficiencies. First, the discussions have been too often piecemeal in character, limited to after-the-fact analyses of particular issues that provoked the debate, and unconnected to larger concepts and themes. Second, a crucial missing element of those discussions has been the failure to reflect explicitly on the diverse disciplinary conceptions of nature and the natural that shape moral judgments about the legitimacy of specific forms of research and their applications.

B. Andrew Lustig, Baruch A. Brody, and Gerald P. McKenny In this second volume of the "Altering Nature" project, we situate specific religious and policy discussions of four broad areas of biotechnology within the context of our interdisciplinary research on concepts of nature and the natural in the first volume (Altering Nature, Concepts of Nature and the Natural in Biotechnology Debates). In the first volume, we invited five groups of scholars to explore the diverse conc- tions of nature and the natural that shape moral judgments about human alterations of nature, as especially exemplified by recent developments in biotechnology. A careful reading of such developments reveals that assessments of them-whether positive or negative-are often informed by different conceptual interpretations of nature and the natural, with differing implications for judgments about the app- priateness of particular alterations of nature. These varying interpretations of nature and the natural often result from the distinctive perspectives that characterize va- ous scholarly disciplines. Therefore, in an effort to explore the variety of meanings that attend discussions of the concepts of nature and the natural, the contributors to the first volume of Altering Nature addressed those concepts from five different disciplinary vantages. A first group of scholars analyzed a range of religious and spiritual perspectives on concepts of nature and the natural. Their research highlighted the thematic, h- torical, and methodological touchstones in those traditions that shape their persp- tives on nature.
