Some, but not all, of the mistakes a person makes when acting in apparently necessary self-defense are reasonable: we take them not to violate the rights of the apparent aggressor. I argue that this is explained by duties grounded in agents' entitlements to a fair distribution of the risk of suffering unjust harm. I suggest that the content of these duties is filled in by a social signaling norm, and offer some moral constraints on the form such a norm can (...) take. (shrink)

The moral importance of liability to harm has so far been ignored in the lively debate about what self-driving vehicles should be programmed to do when an accident is inevitable. But liability matters a great deal to just distribution of risk of harm. While morality sometimes requires simply minimizing relevant harms, this is not so when one party is liable to harm in virtue of voluntarily engaging in activity that foreseeably creates a risky situation, while having reasonable alternatives. On plausible (...) assumptions, merely choosing to use a self-driving vehicle typically gives rise to a degree of liability, so that such vehicles should be programmed to shift the risk from bystanders to users, other things being equal. Insofar vehicles cannot be programmed to take all the factors affecting liability into account, there is a pro tanto moral reason not to introduce them, or restrict their use. (shrink)

This paper examines whether an agent becomes liable to defensive harm by engaging in a morally permissible but foreseeably risk-imposing activity that subsequently threatens objectively unjustified harm. It first clarifies the notion of a foreseeably risk-imposing activity by proposing that an activity should count as foreseeably risk-imposing if an agent may morally permissibly perform it only if she abides by certain duties of care. Those who argue that engaging in such an activity can render an agent liable to defensive harm (...) ground this liability in the luck egalitarian thought that we may justly hold individuals responsible for the consequences of their voluntary choices. Against this, I argue that a luck egalitarian commitment to holding people responsible cannot, by itself, ground liability to defensive harm. It can help ground such liability only against the backdrop of a distributively just society, and only if further considerations speak morally in favour of attaching certain well-defined costs to individuals’ risk-imposing choices. I conclude by suggesting that if an account of liability applies robustly across distributively just and unjust contexts alike, then what grounds an agent’s liability is plausibly not her responsibility for threatening objectively unjustified harm, but her culpability for doing so.

A person drives her well‐maintained car cautiously and alertly to the movies. Freak circumstances send the car out of control. It veers in the direction of a pedestrian whom it will kill unless she, or a third party, blows it up with a grenade. Whether the driver is liable to be thusly killed polarizes debates about the ethics of self‐defense. But debaters frequently conflate the questions of whether and by what means the driver is liable to be killed. The paper (...) separates these questions: it argues the driver's liability to lethal harm need not entail her liability to the grenade. (shrink)

According to an appealing and common view, the moral status of an action – whether it is wrong, for example – is sometimes important in itself in terms of the moral status of other actions – especially those that respond to the original action. This view is especially influential with respect to the criminal law. It is accepted not only by legal moralists but also by adherents of the harm principle, for example. In this paper, I argue against this view. (...) The main arguments emphasize the distinctions between the moral status of actions, consequences, and agents. I argue that what matters, in terms of other actions, is not the moral status of the original action but rather other factors that may be confused with it, such as the moral status of its consequences – whether they are good or bad – and the moral status of the agent – whether she is praiseworthy or blameworthy. The intuitive appeal of the common view is, I argue, at least partly due to a conflation of these factors. Most importantly, once we recall the distinctions between these factors, we can see more clearly that this view lacks a compelling rationale. Or, at least, that it is based on assumptions that, first, are much more controversial than their conclusion, and, second, do not support every aspect of this view – and thus do not offer a unified foundation for this view.

Yitzhak Benbaji argues that those combatants who have agreed to blindly obey their superiors and who are ordered to fight in unjust wars are released from their duty to deliberate about the merits of the acts that they are ordered to perform. This is because their agreements result in the combatants’ permissible lack of a necessary capacity for moral responsibility. Thus, the combatants are not morally responsible for their wrongful acts—their moral responsibility is “transferred” to their superiors. We argue, first, (...) that Benbaji’s own reasoning suggests that the agreements entered into between the combatants and their superiors are not binding and, second, that even if such agreements are binding, those combatants who obey their orders to fight are nevertheless morally responsible for their wrongful acts. Thus, Benbaji has failed to show that the combatants are permitted to act as ordered. By critically examining Benbaji’s view, then, we defend the revisionist position that just and unjust combatants are morally unequal. (shrink)
