The field of bioethics continues to struggle with the problem of cultural diversity: can universal principles guide ethical decision making, regardless of the culture in which those decisions take place? Or should bioethical principles be derived from the moral traditions of local cultures? Ten Have and Gordijn and Bracanovic defend the universalist position, arguing that respect for cultural diversity in matters ethical will lead to a dangerous cultural relativity where vulnerable patients and research subjects will be harmed. We challenge the (...) premises of moral universalism, showing how this approach imports and imposes moral notions of Western society and leads to harm in non-western cultures. (shrink)
