Insights
Objections to "designer babies" often focus on parental intentions, not the genetic technology itself. Arguments against genetic intervention are re-evaluated, suggesting concerns should be addressed differently.
Area of Science:
- Bioethics
- Reproductive Technologies
- Genetics
Background:
- The concept of
- designer babies
- raises significant ethical objections.
- Many criticisms focus on parental desires and intentions rather than the specific genetic methods used.
Purpose of the Study:
- To critically examine common objections to genetic intervention for creating
- designer babies
- .
- To determine if these objections are specific to genetic means or applicable to broader parental intentions.
Main Methods:
- Review of ethical arguments and objections concerning genetic intervention.
- Analysis of the relationship between parental intentions and reproductive practices.
- Logical deconstruction of arguments against
- designer babies
- .
Main Results:
- Common objections to genetic intervention for
- designer babies
- primarily relate to parental intentions, not the technology itself.
- These intentions can be realized through various means, including traditional genetic selection.
- Existing objections do not decisively rule out genetic intervention in pursuit of
- designer babies
- .
Conclusions:
- Concerns about
- designer babies
- are not solely or decisively against the genetic intervention methods.
- Ethical unease requires different arguments, distinct from those targeting specific genetic technologies.
- The debate necessitates a re-evaluation of the ethical grounds for opposing reproductive genetic enhancements.
Abstract:
Though many objections can be levelled against the idea of the practice of genetic intervention to produce 'designer babies', upon examination they are shown to hinge on features which concern parental intentions towards their children, rather than features specific to the means involved. These intentions may be pursued by a variety of social practices which may, though need not, involve a measure of 'traditional' genetic selection (i.e. in terms of the identity and characteristics of the reproducing partners). This paper reviews a number of these objections and, by parity of reasoning, rejects their claim to count specifically or decisively against genetic intervention in pursuit of 'designer babies'. Rejecting these objections does not lead to the endorsement of 'designing babies, but it shows that any unease must be grounded elsewhere and defended by other arguments.
