AbstractThe purpose of this essay is to examine the consistency and coherence of some arguments about abortion. Theological, philosophical, and public policy discussions of abortion are linked by the necessity of understanding the legitimate claims of the fetus on the woman who bears it, as well as on the larger human community. The tools of moral philosophy widely are employed, whether directly or indirectly, to evaluate abortion as one solution to problematic pregnancies. In particular, theologians examining the problem of abortion from the standpoint of normative ethics find it necessary to take into account some of the seminal work in recent moral philosophy. However, the logic of the moral arguments adduced is not always given fully critical attention in either “pro-choice” or “pro-life” positions, whether they be essentially religious, philosophical, or political in character.One logical implement used broadly is the analogical argument. Burdensome pregnancy can be compared to other situations in which the duty of one individual to protect the rights of another either is sustained or is modified. Differences in evaluations of the morality of abortion can be clarified and perhaps reduced by probing the ways in which the morally significant features of fetal dependency, and of maternal and societal obligation, are partly revealed yet partly hidden by the analogical mode of moral argument.
