A common response to ongoing disagreement about abortion has been to look for overlap between the prolife and prochoice sides of the debate. In recent years, however, both opposing camps in the debate have claimed to be able to establish their respective positions on the basis of the same common ground. Faced with the apparent failure of philosophers to settle their differences about abortion by means of shared values, the question naturally arises: what should we do about this? It is (...) possible to discern two main options in the scholarly literature. The first is to keep doing what we are already doing: namely, trying to create consensus on the abortion issue by appealing to analogies designed to reveal common ground. One example of this approach comes from a recent attempt by Charles Camosy to find areas of agreement with Peter Singer and other defenders of abortion.See Charles Camosy, “Common Ground on Surgical Abortion?—Engaging Peter Singer on the Moral Status of Potential Persons,”.

Although the abortion of fetuses with Down syndrome has become commonplace, infanticide is still widely rejected. Generally, there are three ways of justifying the differentiation between abortion and infanticide: by referring to the differences between the moral status of the fetus versus the infant, by referring to the differences of the moral status of the act of abortion versus the act of infanticide, or by separating the way the permissibility of abortion is justified from the way the impermissibility of infanticide (...) is justified. My argument is that none of these ways justifies the abortion of fetuses diagnosed with Down syndrome while simultaneously rejecting infanticide. Either the justification for abortion is consistent with infanticide, or it is implausible to justify abortion while rejecting infanticide. I conclude the article by making some preliminary remarks about how one might manage the situation posed by my argument. (shrink)
