ABSTRACT
The most obvious method of prenatal influence is simply to select those individuals or the genes of those individuals, displaying the desired trait or to select against those individuals with undesired traits or genes. This chapter explores the ethical and regulatory issues evoked by the goal itself. It examines the legitimacy of prenatal attempts to influence traits in isolation from the specific technique used. The chapter argues that the majority of slippery slope arguments are insufficiently specified. It upholds one particular variant as strong enough to ground a prima facie presumption. The chapter explores the idea that permissible prenatal treatment must be distinguished from purportedly impermissible genetic enhancement, the issues raised by resource allocation, and Feinberg's "right to an open future". It focuses on the alleged immoral outcomes potentially sitting on the bottom of slippery slopes. One empirical slippery slope argument is as having a great deal of force.
