Although many scholars have offered different justifications for moral enhancement, this article provides an additional justification by drawing on the underexplored moral norms that arise from the Egba traditional religion, their culture, economy and form of government. In the process, the article demonstrates that the Egba Yoruba tradition is still a viable religion for thinking critically about pressing contemporary issues, contrary to the speculation that traditional African religions will soon die a natural death. The moral imperative that arises from the Egba traditional beliefs and culture is that “one ought to exhibit excellent character.” In that case, the permissibility of moral enhancement will depend on whether individuals likely to be impacted by such enhancement have been consulted and whether such enhancement can foster their capacity to exhibit excellent character in the relevant ways. This article’s approach is significant and promotes global cognitive justice, which is the claim that different knowledge systems ought to be given equal consideration in thinking about—within this context—bioethics issues like moral enhancement.
