  Proponents of liberal eugenics respond that much of what we attempt to do in medicine to create treatments for disease could itself fit under a “drive to mastery” and might likewise question our commitment to being “open to the unbidden” (see Buchanan 2011). Also, if the point is simply that we must be attentive to our inclinations to hubris – we might get carried away in thinking we can enhance appropriately – then we could heed that warning without rejecting the use of genetic technologies to improve our offspring entirely. Other advocates simply deny the value of humility (Glover 2006: 113).
