Moral discourse about medicine: a variety of forms.

Moral evaluations of medical research and care focus on different issues, e.g., clinical choices, public policy and cultural values. Technical ethical concepts and arguments do not suffice for all issues. Analysis of the literature suggests that, in addition to ethical discourse, prophetic, narrative, and policy discourse function morally. The article characterizes each of these forms, and suggests the insufficiency of each if it is taken to be the only mode of analysis.
