:Several lines of reasoning have been employed to both approve and disapprove two of Nicholas Agar’s positions: his argument that the creation of postpersons is imaginable and possible and his inductive argument disfavoring the creation of postpersons. This article discusses a number of these lines of reasoning, arguing that1)The creation of postpersons is imaginable if they are envisaged as morally enhanced beings.2)The creation of postpersons is justified, subject to the condition that we create morally enhanced postpersons.The reason given for the (...) first point is that it is possible to imagine postpersons who are morally enhanced, provided that we consider moral enhancement as an augmented inclination to act in line with how we believe we ought to act. There are two reasons offered for the second point: the first indicates probability, and the second offers proof. That is, if we assume that the higher moral status of postpersons implies their enhanced morality, we can conclude, inductively, that postpersons will not be inclined to annihilate mere persons. For if mere persons have moral inhibitions against obliterating some species of a lower moral status than their own, morally enhanced postpersons will be even less likely to do the same to mere persons. In fact, they might consider it their moral duty to preserve those beings who enabled them to come into existence. Moreover, even if morally enhanced postpersons decide to annihilate mere persons, we can conclude, deductively, that such a decision is by necessity a morally superior stance to the wish of mere persons to continue to exist.

We outline an argument favoring voluntary moral bioenhancement as a response to existential risks humanity exposes itself to. We consider this type of enhancement a solution to the antithesis between the extinction of humanity and the imperative of humanity to survive at any cost. By opting for voluntary moral bioenhancement; we refrain from advocating illiberal or even totalitarian strategies that would allegedly help humanity preserve itself. We argue that such strategies; by encroaching upon the freedom of individuals; already inflict a (...) degree of existential harm on human beings. We also give some pointers as to the desirable direction for morally enhanced post-personhood. (shrink)

This chapter reviews recent philosophical and neuroethical literature on the morality of moral neuroenhancements. It first briefly outlines the main moral arguments that have been made concerning moral status neuroenhancements. These are neurointerventions that would augment the moral status of human persons. It then surveys recent debate regarding moral desirability neuroenhancements: neurointerventions that augment that the moral desirability of human character traits, motives or conduct. This debate has contested, among other claims (i) Ingmar Persson and Julian Savulescu’s contention that there (...) is a moral imperative to pursue the development of moral desirability neuroenhancements, (ii) Thomas Douglas’ claim that voluntarily undergoing moral desirability neuroenhancements would often be morally permissible, and (iii) David DeGrazia’s claim that moral desirability neuroenhancements would often be morally desirable. The chapter discusses a number of concerns that have been raised regarding moral desirability neuroenhancements, including concerns that they would restrict freedom, would produce only a superficial kind of moral improvement, would rely on technologies that are liable to be misused, and would frequently misfire, resulting in moral deterioration rather than moral improvement.
