Parental wisdom, empirical blindness, and normative evaluation of prenatal genetic enhancement.

The purpose of this paper is to unveil one problem that surrounds the debate over the moral standing of prenatal genetic enhancement (PGE) and to outline a solution to it. The problem is that we have no way to test our speculations about the consequences of prenatal enhancement without begging the question about the moral permissibility of enhancing unborn children. The only way to empirically support our speculations about the consequences of prenatal enhancement is to resort to ethically worrisome (and radical) experimental genetic research. The suggested solution to this problem is to focus on the character of good parents. The virtue of parental wisdom is introduced and used as a basis for evaluating PGE. It is argued that good parents have good reason not to condone PGE for their children (in very many cases), especially as part of the first wave of genetically altered humans.
