Choosing Tomorrow's Children

Abstract

To what extent should parents be allowed to use selection technologies (such as preimplantation genetic diagnosis) to determine the characteristics of their children? And is there something morally wrong with parents who wish to do this? Choosing Tomorrow's Children provides answers to these questions. In particular, the book applies the techniques of philosophical bioethics to address issues raised by selective reproduction, the practice of choosing between different possible future persons by selecting or deselecting (for example) embryos, eggs, and sperm. It offers answers to questions including the following. Do children have a ‘right to an open future’ and, if they do, what moral constraints does this place upon selective reproduction? Under what circumstances (if any) should sex selection be allowed? Should we ‘screen out’ as much disease and disability as possible before birth, or would that be an objectionable form of eugenics? Is it acceptable to create or select a future person (a ‘saviour sibling’) in order to provide life-saving tissue for an existing relative? Is there a moral difference between selecting to avoid disease and selecting to produce an ‘enhanced’ child? And should we allow deaf parents to use reproductive technologies to ensure that they have a deaf child? The book does not provide one overarching conclusion but rather assesses each argument-type on its merits. Insofar as it is possible to generalise though, Choosing Tomorrow's Children concludes that most of the arguments usually provided against selective reproduction are flawed in one way or another.
