This commentary, while sympathetic to Thomasma and Pellegrino [15], raises three sets of questions concerning the adequacy of their view of medicine as a foundation for medical ethical decision-making. The first set of questions concerns the account of the nature of medicine presented by Thomasma and Pellegrino. It is argued that the account is not clearly univocal and that even the most important description offered requires further clarification. Questioned, secondly, is the reasoning used by Thomasma and Pellegrino to propel their (...) movement from establishing an evaluative component in medicine to asserting an ethical dimension to medical judgment. It is argued that the authors equivocate in their presentation between the medical and moral uses of value terms. Finally, the role of the living body as a foundation for medical ethics is questioned, both in terms of the normative force such a ground can generate, and in terms of the range of duties to which this foundation must commit the profession.

A rational reconstruction of the role of moral values in diagnostic reasoning is undertaken. In the context of a case study it is shown how value and ethical considerations come into play in the complex course of making diagnostic and therapeutic decisions.
