Brody’s is a significantly looser cognitive
criterion than Boonin’s “organized cortical activity”
criterion because it makes fetal humanity dependent on the
presence of early brain function which is not sufficiently
organized to support consciousness. A difficulty for Brody’s
theory is that determining when brain death has occurred
may be nearly as difficult as determining when personhood
begins. Brain death has proved notoriously difficult to
ascertain because detectable electrical activity can continue
in a brain that has ceased meaningful functioning. One
study shows that at least 20 percent of “brain dead” patients
continued to exhibit electrical activity on electroencephalograms,
some of it compatible with function (Truog, p. 161).
The symmetry Brody appeals to is thus elusive—it may be
no easier to define when personhood ends than it is to define
when it begins.
Both proponents and opponents of abortion believe
that settling the abortion controversy requires settling the
question of personhood. While there is room for agreement
in positions like Boonin’s, Brody’s, and even Marquis’s, at
either extreme standards of personhood like Noonan’s and
Warren’s are incommensurable, leading some to question
the utility of defining personhood as a route to resolving the
abortion conflict. So long as the fetus’s moral standing is
believed to depend on fetal personhood, however, the
question of personhood will not disappear from the abortion
debate.
