Moral enhancement, an instance of human enhancement, alters a person’s dispositions, emotions or behavior in order to make that person more moral. I will argue that moral enhancement could be carried out in three different ways. The first strategy, well known from science fiction, is behavioral enhancement. The second strategy, favored by prominent defenders of moral enhancement, is emotional enhancement. The third strategy is the enhancement of moral dispositions, such as empathy and inequity aversion. I will argue that we ought to implement a combination of the second and third strategies. Furthermore, I will argue that the usual arguments against other instances of human enhancement do not apply to moral enhancement, or apply only to the first strategy, behavioral enhancement.
