 In “The Problem of Abortion and the Doctrine of Double Effect”, (1967) Foot raises a related case that has been the subject of much subsequent discussion: a runaway trolley is headed toward five people who will be killed by the collision, but it could be steered onto a track on which there is only one person (1967 [VV 23]).  Intuitively, it seems permissible to turn the trolley to hit and kill one person, but the problem is that it does not seem permissible to kill one to save five in cases like Rescue II. Why, Foot asks, can we not argue for the permissibility of killing one to save five in those cases by appealing to the Trolley case? As we have seen, Foot argues that negative rights are generally stronger than positive rights. In Rescue II, we must violate someone’s negative rights to meet the positive rights of others, and this is impermissible because the negative rights have priority over the positive rights that is not outweighed by five people’s need for assistance. In Trolley, by contrast, we are not violating negative rights to meet positive rights; the situation pits the negative rights of the five against the negative rights of one, and both choices involve violating someone’s negative rights. In such a case, it seems clearly preferable to minimize the violation of negative rights by turning the trolley (1967 [VV 27]).
