Abstract

Much of the abortion debate has revolved around questions of the ontological status of the fetus: many liberals and conservatives agree that if the fetus is a person in the fullest sense of “person”, it would require very weighty reasons to justify killing it; if, on the other hand, the fetus is not a person in the fullest sense, considerations of less moment should suffice to justify killing it. Resolution of questions about the morality of abortion, thus, should be quite straightforward: stipulate criteria of personhood and determine whether fetuses, in general, or some particular fetus satisfies those criteria. If a fetus satisfies them, it is a person in the fullest sense and has the same right to life as any other person; if it fails to satisfy those criteria, it is not a person in the fullest sense and, thus, does not have the same right to life as a person. Unfortunately, such a programme is easier envisaged than achieved. The literature is laden with controversial analyses of personhood, none of which are acceptable to all parties to the abortion controversy, and, thus, discussions of the morality of abortion continue at a shrill level; unable to find any common ground from which to initiate reasoned discourse the two sides talk past each other and no progress is made.
