Abstract
Disagreements about abortion are often assumed to reduce to disagreements
about fetal personhood (and mindedness). If one believes a fetus is a person (or has a
mind), then they are “pro-life.” If one believes a fetus is not a person (or is not minded),
they are “pro-choice.” The issue, however, is much more complicated. Not only is it
not dichotomous—most everyone believes that abortion is permissible in some
circumstances (e.g. to save the mother’s life) and not others (e.g. at nine months of a
planned pregnancy)—but scholars on both sides of the issue (e.g. Don Marquis and
Judith Thomson) have convincingly argued that fetal personhood (and mindedness) are
irrelevant to the debate. To determine the extent to which they are right, this article will
define “personhood,” its relationship to mindedness, and explore what science has
revealed about the mind before exploring the relevance of both to questions of
abortion’s morality and legality. In general, this article does not endorse a particular
answer to these questions, but the article should enhance the reader’s ability to develop
their own answers in a much more informed way.
