Genetics: Can Moral Theology Help?

Abstract

The article discusses Marc Lappé's use of the Principle of Double Effect (PDE) for justifying Germ Line Gene Therapy as a secondary effect of Somatic Gene Therapy. The author argues that Lappés argumentation is mistaken because it is based on a inadequate interpretation of the PDE's scope and function as a means of moral justification. Through an investigation into the history of PDE in Catholic theology, the author gives arguments that use of PDE relies upon some form of deontological framework which is not present in contemporary bioethics. The author concludes that isolated use of PDE, as Lappé seems to suggest, does therefore not warrant moral justification.
