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,”.

Medical stem cell research is currently the cause of much moral controversy. Those who would confer the same moral status to embryos as we do to humans consider that harvesting such embryonic cells entails sacrificing embryos. In this paper, the author analyses critically the arguments given for such a perspective. Finally, a theory of moral status is outlined that coherently and plausibly supports the use of embryonic stem cells in therapeutic research.
