Unfit for the Future argues that the future of our species depends on radical enhancement of the moral aspects of our nature. Population growth and technological advances are threatening to undermine the conditions of worthwhile life on earth forever. We need to modify the biological bases of human motivation to deal with this challenge.

A number of philosophers working in applied ethics and bioethics are now earnestly debating the ethics of what they term “moral bioenhancement.” I argue that the society-wide program of biological manipulations required to achieve the purported goals of moral bioenhancement would necessarily implicate the state in a controversial moral perfectionism. Moreover, the prospect of being able to reliably identify some people as, by biological constitution, significantly and consistently more moral than others would seem to pose a profound challenge to egalitarian (...) social and political ideals. Even if moral bioenhancement should ultimately prove to be impossible, there is a chance that a bogus science of bioenhancement would lead to arbitrary inequalities in access to political power or facilitate the unjust rule of authoritarians; in the meantime, the debate about the ethics of moral bioenhancement risks reinvigorating dangerous ideas about the extent of natural inequality in the possession of the moral faculties.

We respond to a number of objections raised by John Harris in this journal to our argument that we should pursue genetic and other biological means of morally enhancing human beings (moral bioenhancement). We claim that human beings now have at their disposal means of wiping out life on Earth and that traditional methods of moral education are probably insufficient to achieve the moral enhancement required to ensure that this will not happen. Hence, we argue, moral bioenhancement should be sought (...) and applied. We argue that cognitive enhancement and technological progress raise acute problems because it is easier to harm than to benefit. We address objections to this argument. We also respond to objections that moral bioenhancement: (1) interferes with freedom; (2) cannot be made to target immoral dispositions precisely; (3) is redundant, since cognitive enhancement by itself suffices.

This article draws attention to several common mistakes in thinking about biomedical enhancement, mistakes that are made even by some supporters of enhancement. We illustrate these mistakes by examining objections that John Harris has recently raised against the use of pharmacological interventions to directly modulate moral decision-making. We then apply these lessons to other influential figures in the debate about enhancement. One upshot of our argument is that many considerations presented as powerful objections to enhancement are really strong considerations in (...) favour of biomedical enhancement, just in a different direction. Another upshot is that it is unfortunate that much of the current debate focuses on interventions that will radically transform normal human capacities. Such interventions are unlikely to be available in the near future, and may not even be feasible. But our argument shows that the enhancement project can still have a radical impact on human life even if biomedical enhancement operated entirely within the normal human range. (shrink)
