"Green has actively engaged the topic of genetic engineering by not only providing the latest science, but by presenting arguments with all their attendant emotional baggage. The combination is a powerful one, but comes off exceptionally well."--Eric M. Meslin, Indiana University Center for Bioethics -- Eric M. Meslin, "Not only is Green's scholarship rock-solid, he is also the most balanced and thoughtful of the many analysts in this area--neither an avid supporter who believes in science above all, nor an arch conservative who would take us back to the dark ages."--Dean H. Hamer, molecular biologist and author of "The Science of Desire, Living with Our Genes" and "The God Gene" -- Dean H. Hamer, "With his close and sound attention to the relevant science and his attention to the relevant religious, ethical, and policy perspectives and debates, Green has offered a well-integrated set of arguments that can serve to educate and guide students in courses in college and policy makers alike."--James F. Childress, John Allen Hollingsworth Professor of Ethics, Institute for Practical Ethics and Public Life, University of Virginia -- James F. Childress, "Green presents ethical positions and arguments in the context of modern thought, and in a language that will be accessible to scholars, scientists and lay-people."--Lee Silver, Princeton University, "This is a brilliant and provocative book by one of the top--and most visionary--bioethicists in the world. It takes us into the era of directed human evolution, which may soon redefine people's relationships, capabilities, and even our concepts of freedom and justice."--Robert Lanza, Vice President of Research and Scientific Development at Advanced Cell Technology
