The parental love argument against ‘designing’ babies: The harm in knowing that one has been selected or enhanced

In this chapter, I argue that children who were selected for particular traits or genetically enhanced might feel, for this reason, less securely, spontaneously and fairly loved by their parents, which would constitute significant harm. ‘Parents’ refers, throughout this chapter, to the people who perform the social function of rearing children, rather than to procreators. I rely on an understanding of adequate parental love which includes several characteristics: parents should not make children feel they are loved conditionally, for features such as intelligence, looks or temperament; they should not burden children with parental expectations concerning particular achievements of the child; and parental love is often expressed in spontaneous enjoyment and discovery of children’s features. This understanding of parental love provides a reason to question the legitimacy of parental use of selection and enhancement and to explain why parents should not engage on a quest for the ‘best child’.
