RT Journal Article SR Electronic T1 Strengthening the impairment argument against abortion JF Journal of Medical Ethics JO J Med Ethics FD BMJ Publishing Group Ltd and Institute of Medical Ethics SP 515 OP 518 DO 10.1136/medethics-2020-106153 VO 47 IS 7 A1 Bruce Philip Blackshaw A1 Perry Hendricks YR 2021 UL http://jme.bmj.com/content/47/7/515.abstract AB Perry Hendricks’ impairment argument for the immorality of abortion is based on two premises: first, impairing a fetus with fetal alcohol syndrome (FAS) is immoral, and second, if impairing an organism to some degree is immoral, then ceteris paribus, impairing it to a higher degree is also immoral. He calls this the impairment principle (TIP). Since abortion impairs a fetus to a higher degree than FAS, it follows from these two premises that abortion is immoral. Critics have focussed on the ceteris paribus clause of TIP, which requires that the relevant details surrounding each impairment be sufficiently similar. In this article, we show that the ceteris paribus clause is superfluous, and by replacing it with a more restrictive condition, the impairment argument is considerably strengthened.There are no data in this work.
