At the edge of mortality there is a place where the seriously ill or dying wait—a place where they may often feel vulnerable or alone. For over forty years, bioethicist cum philosopher Richard Zaner has been at the side of many of those people offering his incalculable gift of listening, and helping to lighten their burdens—not only with his considerable skills, but with his humanity as well.

The narratives Richard Zaner shares in Conversations on the Edge are informed by his depth of knowledge in medicine and bioethics, but are never "clinical." A genuine and caring heart beats underneath his compassionate words. Zaner has written several books in which he tells poignant stories of patients and families he has encountered; there is no question that this is his finest.

In Conversations on the Edge, Zaner reveals an authentic empathy that never borders on the sentimental. Among others, he discusses Tom, a dialysis patient who finally reveals that his inability to work—encouraged by his overprotective mother—is the source of his hostility to treatment; Jim and Sue, young parents who must face the nightmare of letting go of their premature twins, one after the other; Mrs. Oland, whose family refuses to recognize her calm acceptance of her own death; and, in the final chapter, the author's mother, whose slow demise continues to haunt Zaner's professional and personal life.

These stories are filled with pain and joy, loneliness and hope. They are about life and death, about what happens in hospital rooms—and that place at the edge—when we confront mortality. It is the rarest of glimpses into the world of patients, their families, healers, and those who struggle, like Zaner, to understand.

What, exactly, does it mean to be human? It is an age-old question, one for which theology, philosophy, science, and medicine have all provided different answers. But though a unified response to the question can no longer be taken for granted, how we answer it frames the wide range of different norms, principles, values, and intuitions that characterize today's bioethical discussions. If we don't know what it means to be human, how can we judge whether biomedical sciences threaten or enhance our humanity?

This fundamental question, however, receives little attention in the study of bioethics. In a field consumed with the promises and perils of new medical discoveries, emerging technologies, and unprecedented social change, current conversations about bioethics focus primarily on questions of harm and benefit, patient autonomy, and equality of health care distribution. Prevailing models of medical ethics emphasize human capacity for self-control and self-determination, rarely considering such inescapable dimensions of the human condition as disability, loss, and suffering, community and dignity, all of which make it difficult for us to be truly independent.

In Health and Human Flourishing, contributors from a wide range of disciplines mine the intersection of the secular and the religious, the medical and the moral, to unearth the ethical and clinical implications of these facets of human existence. Their aim is a richer bioethics, one that takes into account the roles of vulnerability, dignity, integrity, and relationality in human affliction as well as human thriving. Including an examination of how a theological anthropology—a theological understanding of what it means to be a human being—can help us better understand health care, social policy, and science, this thought-provoking anthology will inspire much-needed conversation among philosophers, theologians, and health care professionals.

In Replacement Parts, internationally recognized bioethicist Arthur L. Caplan and coeditors James J. McCartney and Daniel P. Reid assemble seminal writings from medicine, philosophy, economics, and religion that address the ethical challenges raised by organ transplantation. Caplan's new lead essay explains the shortfalls of present policies. From there, book sections take an interdisciplinary approach to fundamental issues like the determination of death and the dead donor rule; the divisive case of using anencephalic infants as organ donors; the sale of cadaveric or live organs; possible strategies for increasing the number of available organs, including market solutions and the idea of presumed consent; and questions surrounding transplant tourism and "gaming the system" by using the media to gain access to organs.

Timely and balanced, Replacement Parts is a first-of-its-kind collection aimed at surgeons, physicians, nurses, and other professionals involved in this essential lifesaving activity that is often fraught with ethical controversy.
