Observations on the epistemological status of bioethics.

Different definitions of bioethics in American and Italian literature are reported. It is argued that they refer to three different conceptions of the epistemological status of bioethics: the first conceives of it as an application of moral principles to biomedical problems, the second as a methodology for the working out of clinical judgement, the third as a broader and interdisciplinary public inquiry. It is suggested that each approach grasps a part of the truth, for each singles out one level of the bioethical work. Bioethics is in fact a complex, three-level form of knowledge. The misunderstanding of this complexity has led to some confusion and to conflicts of attribution among those who are concerned with it.
