In response to criticism of the impairment argument for the immorality of abortion, Bruce Blackshaw and Perry Hendricks appeal to Don Marquis’s future-like-ours (FLO) account of the wrongness of killing to explain why knowingly causing fetal impairments is wrong. I argue that wedding the success of the impairment argument to FLO undermines all claims that the impairment argument for the immorality of abortion is novel. Moreover, I argue that relying on FLO when there are alternative explanations for the wrongness of (...) causing FAS begs the question. I conclude, therefore, that the impairment argument remains unsuccessful. (shrink)

In his recent article “Even if the fetus is not a person, abortion is immoral: The Impairment Argument,” Perry Hendricks sets out to sidestep thorny metaphysical questions regarding human fetuses and present a new argument against abortion – if impairing a fetus with fetal alcohol syndrome is immoral, then killing the fetus is immoral. Hendricks takes inspiration from Judith Jarvis Thomson’s defense of abortion – that even if fetuses are persons with a right to life, the right to life is (...) not the right to use others, so it is acceptable to induce abortion. Together with Bruce Blackshaw, Hendricks set out to strengthen the impairment argument by appealing to Don Marquis’s future like ours (FLO) account of the wrongness of killing. Here I argue the impairment argument falls short in three ways. First, Hendricks and Blackshaw fail to assume fetuses aren’t persons, broadly construed. Second, they fail to show that impairing a fetus is immoral. Third, they overlook abortions that (merely) let the fetus die. Finally, I argue Thomson’s defense of abortion preempts the significance of the impairment argument; Thomson seems to show that even if killing a fetus is prima facie immoral, women still have the right to induce abortion.
