Global bioethics and respect for cultural diversity: how do we avoid moral relativism and moral imperialism?

One of the major concerns of advocates of common morality is that respect for cultural diversity may result in moral relativism. On their part, proponents of culturally responsive bioethics are concerned that common morality may result in moral imperialism because of the asymmetry of power in the world. It is in this context that critics argue that global bioethics is impossible because of the difficulties to address these two theoretical concerns. In this paper, I argue that global bioethics is possible if we adopt a culturally responsive and self-critical attitude towards our moral values and those of others. I use the example of women's reproductive autonomy in indigenous African culture to show that the difference between the leading Euro-American and indigenous African construal of autonomy is that the former ascribes greater weight on individual self-determination while the latter emphasizes responsibilities towards the community. One develops dignity in virtue of their capacity for communing with others. Hence, women have rights, but as members of the community, they also have obligations including the duty to procreate. The involvement of the family in reproductive decisions does not contravene women's dignity and human rights. In applying the principle of autonomy in this communitarian context, one has to be sensitive to these ontological and moral specificities. The aim of global bioethics should not be to reach common grounds at all costs; any common norms should be the result of a negotiated democratic dialogue between cultures and not the result of imposition by the preponderant culture(s).
