 In cases involving less severe disabilities, some prospective parents think that they are protecting the welfare of “their child” by preventing the existence of a child who would have a disability. This attitude involves seeing the future child not as a particular individual who can only exist with a disability, but as a role that prospective parents do not want to fill with a disabled child. Philosophers have debated the appropriateness of regarding future children in this way (Malek 2008; Hare 2007; Velleman 2008; Wasserman 2008; Heyd 2009). Even if this view were appropriate, its moral force would depend on the extent to which the diagnosed condition could reasonably be expected to reduce the child’s welfare, as well as the existence and strength of a moral reason not to bring into existence persons with such welfare deficits.
