Abstract

According to Jonathan Quong’s _moral status account_ of liability to defensive harm, an agent is liable to defensive harm only when she mistakenly treats others as if their moral status is diminished (for example, as if they lack a right that they in fact possess). Quong argues that, by the lights of the moral status account, a conscientious driver (Driver) who faultlessly threatens to kill Pedestrian is not liable to defensive harm. Quong argues that Driver’s action is evidence-relative permissible, despite the risks it imposes, because the general practice of prudent driving is permissible. The practice is permissible because (a) its risks do not disproportionately fall on some groups rather than others, (b) the threatened harms are incidental, and (c) the risk that driving imposes is acceptable in light of the benefits everyone derives from driving. Because the correct moral theory tells us that prudent driving is permissible, Pedestrian lacks a right that Driver refrain from driving. Hence, Driver does not, by driving, treat Pedestrian as lacking a right that Pedestrian in fact possesses. Driver is not liable to defensive force. I argue, against Quong, that cost–benefit analyses of types of risky activity cannot justify individual tokens of risk imposition. Actions that risk incidentally harming others must be justified by the prospective benefits of that token action. Hence, Driver’s imposition of risk on Pedestrian cannot be justified by the benefits of the general practice of driving. I argue that the permissibility of Driver’s imposing risk on Pedestrian via prudent driving turns on whether Driver is willing to internalise at least the foreseeable costs of that risky action. One can lack a right that a person refrain from performing a risky action whilst possessing a right not to be harmed by that risky action. Even if Pedestrian cannot reasonably demand that Driver refrain from driving, she can reasonably demand that Driver refrain from forcing her to bear the costs of his driving.
