  Concern with the effects of reprogenetics on human nature are also present in proponents of liberal eugenics. For instance, Glover proposes two potential features of great value in our current nature: our capacity to rein in our violent and destructive tendencies, and our capacity to aim for a good life (for Glover, this is about a balance between happiness and flourishing). These are very tentatively offered, with many qualifications about possible linkages to other traits of value, and the likelihood that we might be more successful in securing containment through non-genetic means. Still, the suggestion is that if parents might be tempted to select for genetic markers linked to, for instance, extreme selfishness or emotional coldness, in an attempt to have their child succeed in gaining power and riches, doing so would seem to endanger parts of our nature that we can widely agree are deeply valuable for society as a whole.
