An abstract of his talk is as follows:
Most of us take it for granted that what we believe to be liberal, humane views about abortion, genetic therapy for cognitive impairment, and prenatal injury must all be compatible. My talk will challenge this comfortable assumption. I will suggest that the possible reasons we might have to provide genetic therapy for a cognitively impaired fetus are also equally strong reasons not to have an abortion. I then argue that what seems to be the obvious way for those with liberal views about abortion to avoid this dilemma has wholly unacceptable implications concerning the infliction of prenatal injury.
