Lives worth living and the danger of ignoring non-identity limits on genetic preference.

Abstract

In this short paper, I detail a case against Dr Guido Pennings's latest publication in the Journal of Medical Ethics, titled 'The moral obligation to have genetically related children". I argue that Pennings, despite raising awareness of issues of bioethical and scientific import, fatally neglects to interact with a central debate in reproductive ethics: the non-identity problem (NIP). Taking the NIP seriously, we can see that the moral obligation that Pennings argues for falls victim to the same kinds of issues as the principle of procreative beneficence, which Pennings also cites. This response then considers the possibility of damaging upshots if Pennings's arguments were read uncritically.
