*A rigorous philosophical analysis of some of the most disputed questions in Catholic sexual ethics*

The Perspective of the Acting Person introduces readers to one of the most important and provocative thinkers in contemporary moral philosophy

At the onset of Life, Liberty and the Defense of Dignity, Leon Kass gives us a status report on where we stand today: “Human nature itself lies on the operating table, ready for alteration, for eugenic and psychic ‘enhancement,’ for wholesale redesign. In leading laboratories, academic and industrial, new creators are confidently amassing their powers and quietly honing their skills. For anyone who cares about preserving our humanity, the time has come for paying attention.” Trained as a medical doctor and biochemist, Dr. Kass has become one of our most provocative thinkers on bioethical issues. In Life, Liberty and the Defense of Dignity, he has written a book that grapples with the moral meaning of the new biomedical technologies now threatening to take us back to the future envisioned by Aldous Huxley in Brave New World. In a series of mediations on cloning, embryo research, the sale of organs, and the assault on mortality itself, Kass questions the wisdom of trying to break down the natural boundaries given us and to remake the human body into an instrument of our will. He also attempts to chart a course by which we might avoid the dehumanization of biotechnical “recreationism” without rejecting modern science or rejecting its genuine contributions to human welfare. Leon Kass writes profoundly about the limits of science and the limits of life, about what makes us human and gives us human dignity. Life, Liberty and the Defense of Dignity.

We humans can enhance some of our mental and physical abilities above the normal upper limits for our species with the use of particular drug therapies and medical procedures. We will be able to enhance many more of our abilities in more ways in the near future. Some commentators have welcomed the prospect of wide use of human enhancement technologies, while others have viewed it with alarm, and have made clear that they find human enhancement morally objectionable. The Ethics of Human Enhancement examines whether the reactions can be supported by articulated philosophical reasoning, or perhaps explained in terms of psychological influences on moral reasoning. An international team of ethicists refresh the debate with new ideas and arguments, making connections with scientific research and with related issues in moral philosophy.

Defending Life is arguably the most comprehensive defense of the pro-life position on abortion - morally, legally, and politically - that has ever been published in an academic monograph. It offers a detailed and critical analysis of Roe v. Wade and Planned Parenthood v. Casey as well as arguments by those who defend a Rawlsian case for abortion-choice, such as J. J. Thomson. The author defends the substance view of persons as the view with the most explanatory power. The substance view entails that the unborn is a subject of moral rights from conception. While defending this view, the author responds to the arguments of thinkers such as Boonin, Dworkin, Stretton, Ford and Brody. He also critiques Thomson's famous violinist argument and its revisions by Boonin and McDonagh. Defending Life includes chapters critiquing arguments found in popular politics and the controversy over cloning and stem cell research.

This volume contributes to the growing literature on the morality of procreation and parenting. About half of the chapters take up questions about the morality of bringing children into existence. They discuss the following questions: Is it wrong to create human life? Is there a connection between the problem of evil and the morality of procreation? Could there be a duty to procreate? How do the environmental harms imposed by procreation affect its moral status? Given these costs, is the value of establishing genetic ties ever significant enough to render procreation morally permissible? And how should government respond to peoples' motives for procreating? The other half of the volume considers moral and political questions about adoption and parenting. One chapter considers whether the choice to become a parent can be rational. The two following chapters take up the regulation of adoption, focusing on whether the special burdens placed on adoptive parents, as compared to biological parents, can be morally justified. The book concludes by considering how we should conceive of adequacy standards in parenting and what resources we owe to children. This collection builds on existing literature by advancing new arguments and novel perspectives on existing debates. It also raises new issues deserving of our attention. As a whole it is sure to generate further philosophical debate on pressing and rich questions surrounding the bearing and rearing of children.
