Bioethics after God explores the relationship between morality and medicine in a society that has denied the existence of God.

Medicine and bioethics are going through profound changes in the Western world. Practices that prior generations would have recognized as morally impermissible, such as abortion, eugenics, and euthanasia, are becoming central components of modern health care. Bioethics after God argues that in the process of rejecting its Christian roots, the Western world has upended traditional understandings of truth that are central to both scientific and moral judgment. The effect is felt throughout medicine as health care professionals increasingly work without the context and guidance provided by traditional Christian ethics.

Cherry uses the conceptual framework of "weak bioethics"—bioethics solely informed by the stark limits of secular morality—to delve into shifting concepts of health and disease, the active embrace of ethically fraught practices, and technological developments such as brain transplantation and humanoid robots designed for sexual activity. The implications of a bioethics after God are wide-ranging and profound, and Cherry challenges us to consider the repercussions of pushing forward in medicine without the support of a solid ethical foundation.
