Kyle van Oosterum and Emma Curran have recently argued that the impairment argument against abortion is weak and accomplishes little. They also claim that impairment fails to explain what makes giving a child fetal alcohol syndrome (FAS) immoral, which is an important premise of the argument. Here, I explain that the impairment argument is not as weak as they believe. Further, I argue that impairment offers a superior explanation for what makes giving a child FAS immoral than their proposal based (...) on creative beneficence. (shrink)

Bruce Blackshaw and Perry Hendricks have recently developed and defended the impairment argument against abortion, arguing that the immorality of giving a child fetal alcohol syndrome (FAS) provides us with reason to believe that abortion is immoral. In this paper we forward two criticisms of the impairment argument. First, we highlight that, as it currently stands, the argument is very weak and accomplishes very little. Second, we argue that Blackshaw and Hendricks are fundamentally mistaken about what makes giving a child (...) FAS immoral. Once we acknowledge this, it is clear that our intuitions about giving a child FAS provide no support for the supposed immorality of abortion. (shrink)

Could it be that if a fetus is not a person abortion is still immoral? One affirmative answer comes in the form of ‘The Impairment Argument’, which utilizes ‘The Impairment Principle’ to argue that abortion is immoral even if fetuses lack personhood. I argue ‘The Impairment Argument’ fails. It is not adequately defended from objections, and abortion is, in fact, a counterexample to the impairment principle. Furthermore, it explains neither what the wrong-making features of abortion are nor what features of (...) fetuses ground their supposed moral significance. By presupposing the fetus lacks personhood and providing no alternate account of the basis of fetuses’ moral significance, there is nothing to constitute abortion’s wrongness. Attempts to modify it fail for the same reasons. Thus, the impairment argument fails to show abortion is immoral. (shrink)

I argue here that the impairment principle requires clarification. It needs to explain what makes one impairment greater than another, otherwise we will be unable to make the comparisons it requires, the ones that enable us to determine whether b really is a greater impairment than a, and as a result, whether causing b is immoral because causing a is. I then develop two of what I think are the most natural accounts of what might make one impairment greater than (...) another. The quantitative understanding of greater impairment is problematic because it leaves the impairment principle vulnerable to counterexamples; just because impairment b impairs a larger number of abilities or the same number of abilities but for a longer period or to a higher degree does not mean that b is a greater impairment than a. The qualitative understanding of greater impairment is problematic because it does not explain examples of greater impairment used in the literature, means that an abortion is always a qualitatively more severe impairment than causing fetal alcohol syndrome regardless of how the organism is affected, and/or entails that lethal impairment is always greater than nonlethal impairment.

Blackshaw and Hendricks recently developed a strengthened version of the impairment argument (SIA) that imports Marquis’ account of the wrongness of abortion. I then argued that if SIA imports Marquis’ account, then it restates Marquis’ position and thus is not very significant. In turn, Blackshaw and Hendricks explained why they take SIA to be importantly different from Marquis’ account. I have two aims in this response. First, I reconstruct Blackshaw and Hendricks’ arguments for the claim that SIA is importantly different (...) from Marquis’ account. Second, I argue that SIA is not importantly different from Marquis’ account in the respect that Blackshaw and Hendricks take it to be. (shrink)

Perry Hendricks’ ‘impairment argument’, which he has defended in this journal, is intended to demonstrate that the generally conceded wrongness of giving a fetus fetal alcohol syndrome (FAS) shows that abortion must also be immoral, even if we allow that the fetus is not a rights-bearing moral person. The argument fails because the harm of causing FAS is extrinsic but Hendricks needs it to be intrinsic for it to show anything about abortion. Either the subject of the wrong of causing (...) FAS is a person who does not exist in the case of abortion or the wrong is negligible. (shrink)

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)

I provide an updated version of The Impairment Argument against abortion and respond to numerous objections that can be (and have been) raised to it.
