In this paper, I supplement T. A. Cavanaugh’s arguments against physician-assisted suicide in his book, Hippocrates’ Oath and Asclepius’ Snake, by focusing more specifically on the dangers of the misuse of physician power and on the virtues essential to restrain such power. Since Cavanaugh’s starting point is similar to Edmund Pellegrino’s views on the fundamental ends of medicine, I start with the question of the proper ends of medicine. Cavanaugh’s interpretation of the Hippocratic Oath as the limitation of physician power (...) to heal and to kill raises the issue of the proper use of physician power over the patient. In order to support and strengthen Cavanaugh’s case, I use Richard Zaner’s discussion of physician power over the patient and the attendant duty to use such power in a responsible way. Finally, I supplement Cavanaugh’s discussion with a fuller account of physician virtues as they relate to physician-assisted suicide. I first discuss the ends of medicine, medical power, and physician-assisted suicide. Second, I discuss the relationship between virtue and physician-assisted suicide. Third, I draw some final conclusions. (shrink)
