What kind of doing is clinical ethics?

This paper discusses the importance of Richard M. Zaner's work on clinical ethics for answering the question: what kind of doing is ethics consultation? The paper argues first, that four common approaches to clinical ethics -- applied ethics, casuistry, principlism, and conflict resolution cannot adequately address the nature of the activity that makes up clinical ethics; second, that understanding the practical character of clinical ethics is critically important for the field; and third, that the practice of clinical ethics is bound up with the normative commitments of medicine as a therapeutic enterprise.
