Respect for cultural diversity and the empirical turn in bioethics: A plea for caution

In the last two decades,there have been numerous calls for a culturally sensitive bioethics. at the same time,bioethicists have become increasingly involved in empirical research,which is a sign of dissatisfaction with the analytic methods of traditional bioethics. in this article,i will argue that although these developments have broadened and enriched the field of bioethics,they can easily be construed to be an endorsement of ethical relativism,especially by those not well grounded in academic moral philosophy. i maintain that bioethicists must resist the temptation of moving too quickly from cultural relativism to ethical relativism and from empirical findings to normative conclusions. indeed,anyone who reasons in this way is guilty of the naturalistic fallacy. i conclude by saying that properly conceptualized,empirical research and sensitivity to cultural diversity should give rise to objective rational discourse and criticism and not indiscriminate tolerance of every possible moral practice. bioethics must remain a normative discipline that is characterized by rigorous argumentation. © 2012 karori mbugua; licensee tehran univ. med. sci.
