5. Although there may be concerns about CE in general, when autonomous adults are concerned there is less contention, partly because of the right to respect for autonomy.

7. I deliberately draw a distinction between “ends” and “outcomes” of CE interventions: the ends are the goals being pursued (whether successfully or not), whereas the outcomes are the actual results achieved.

14. This condition of governing oneself entails the possession and practice of certain virtues, such as self-determination, authenticity, and self-legislation (among others). This raises many questions about the precise nature and extent of autonomy; however, an in-depth critique of Feinberg’s approach is beyond the scope of this article. See Feinberg J. Autonomy.

22. Davis acknowledges that the case of the Amish appears relatively uncontroversial because of the Amish’s particular characteristics. However, she gives the example of female genital mutilation (FGM) to point out the importance of protecting a child’s open future from any infringement for the sake of community values or membership.

28. This explains the case of the Amish, in which the future option of becoming full members of the community might well be taken away from children in favor of their future capacity to make their own self-determined decisions about their lives.

29. Parental authority and/or choice have different origins in law and in philosophy. Whereas in law all rights of parents ultimately derive from their responsibility for their children, philosophy also recognizes parental autonomy as an ethical value.

30. Davis believes that the concept of the child’s right to an open future provides a new pathway toward resolving the tension between “the beneficence model of patient care and the rights of parents to their own autonomy and to the protection of their family units.” See note 6, Davis 2010, at 98.

37. That this results in treatment as mere means seems unlikely, and mixed motives appear more plausible, as is often argued in the case of savior siblings, when children are created/selected for a specific purpose, but are also loved for themselves.

38. A view I do not share. See note 3, Krutzinna 2016, at 530. Moen later clarifies that he does not believe in the intrinsic value but rather the instrumental value of intelligence. Moen OM. Smarter Babies. Cambridge Quarterly of Healthcare Ethics 2016;25(3):515–17, at 515.

Cognitive enhancement in healthy children will not close the achievement gap in education.

The authors also point out that at least in the United States, some schools already require the administration of stimulants to students with certain behavioural profiles, and they caution that “[m]andated prescriptions establish an educational process in which the failure to meet specific behavioral expectations is thought to warrant a physical intervention aimed at changing the brain chemistry of the child—the strategic alteration of the child’s dispositions, regardless of the child’s (or her parent’s) dissent.”

66. See note 39, Sandberg 2011, at 84: “We face many pressing problems which we would be better able to solve if we were smarter or more creative.

69. In a particularly pessimistic scenario, one could argue that parents are selfishly motivated by what is good for them, rather than only by what is good for their children. The truth in most cases probably lies somewhere in between.

70. For example, parents might hope for a particularly beautiful or smart child in the hope that this will automatically translate into success and/or happiness.
