Genetic Engineering and the Consent of Future Persons

The debate over whether germ-line genetic engineering is justified on the basis of the consent or presumed consent of future generations is mired in philosophical confusion. Because of this, the principle of informed consent fails to provide a reason to restrict germ-line genetic engineering. Most recent bioethicists ground the consent requirement on individual autonomy. While conceptually coherent, the notion of individual autonomy also fails to provide a reason for prohibiting germline genetic engineering. Moreover, it offers little in the way of useful guidance for regulating genetic engineering. I argue, however, that respect for autonomy in the sense of moral agency – the ability to reflect on moral considerations and conform one’s behavior to those reflections – provides a principle that can be used for a nuanced evaluation of proposals for genetic engineering.
