Procreative beneficence

Procreative beneficence is the controversial putative moral obligation of parents in a position to select their children, for instance through preimplantation genetic diagnosis (PGD), to favor those expected to have the best life. An argument in favor of this principle is that traits (such as empathy, memory, etc.) are "all-purpose means" in the sense of being instrumental in realizing whatever life plans the child may come to have.
