This essay argues on behalf of a hybrid theory for an ethics of self-defense understood as the Forfeiture-Partiality Theory. The theory weds the idea that a malicious attacker forfeits the right to life to the idea that we are permitted to prefer one's life to another's in cases of involuntary harm or threat. The theory is meant to capture our intuitions both about instances in which we can draw a moral asymmetry between attacker and victim and cases in which we (...) cannot. I develop the theory by attending to instances of intentional, villainous harm and instances of involuntary danger—the latter of which are a matter of bad luck. I call some bad luck cases "Interpersonal Lottery Conflicts." These cases refer to potentially lethal conflicts into which parties are thrown as victims of circumstance. Although neither party has a moral advantage over another, that fact does not preclude permissible self-defense. (shrink)

Two conditions guiding permissible use of force in self-defence are proportionality and success. According to the proportionality condition the means used to prevent an attack can be permissible only if they are proportional to the interest at stake.1 According to the success condition, otherwise impermissible acts can be justified under the right to self-defence only if they are likely to succeed in preventing the perceived threat.2 These requirements should not always be interpreted narrowly. Sometimes people are permitted to kill culpable (...) aggressors in order to avoid a non-lethal harm. Sometimes people are permitted to take up arms to defend themselves against culpable aggressors they have little or no hope of .. (shrink)

In his provocative book War and Self-Defense, David Rodin criticizes attempts to justify national defense based on an analogy between the individual and the state. In doing so, he treats state personality as an analogy to the personality of the individual. Yet the state possesses the key attributes of moral personality, including a conception of the good life and a sense of justice. The state's unobservable — but nevertheless real — moral personality means that it also possessed the right to (...) defend the continued existence of that personality against an attack. Subject to the same constraints that are placed on individuals, such as necessity and proportionality, the state possesses the right to national defense based on its own personality. (shrink)
