Abstract

A growing chorus of voices is declaring that CRISPR will revolutionize the ability to control life, including human life. As genetically altering future generations becomes technically realistic, it raises the prospect of genetic enhancement and the specter of eugenics. Prominent scientists are calling for international guidelines to govern human applications of gene-editing technology. They argue that the technical possibility of human germline gene editing makes ethical deliberation urgent. Now that the technology is upon us, the time has come to ask whether we want it. Human germline genetic engineering has long been marked as a morally significant boundary, and in numerous countries it is explicitly prohibited by law. The Oviedo Convention, a legally binding treaty among twenty-nine European countries, prohibits it as a violation of human rights and dignity. Nevertheless, numerous commentators argue that prohibitions made before it was technically possible meant little, and past proscriptions must now be revised.
