Minimal responsibility threateners are epistemically justified but mistaken in thinking that imposing a nonnegligible risk on others is permissible. On standard accounts, an MRT forfeits her right not to be defensively killed. I propose an alternative account: an MRT is liable only to the degree of harm equivalent to what she risks causing multiplied by her degree of responsibility. Harm imposed on the MRT above that amount is justified as a lesser evil, relative to allowing the MRT to kill her (...) victim. This hybrid account, which generalizes to those are who are more than minimally responsible, has considerable advantages. (shrink)

Jeff McMahan rejects the relevance of desert to the morality of self-defense. In Killing in War he restates his rejection and adds to his reasons. We argue that the reasons are not decisive and that the rejection calls for further attention, which we provide. Although we end up agreeing with McMahan that the limits of morally acceptable self-defense are not determined by anyone’s deserts, we try to show that deserts may have some subsidiary roles in the morality of self-defense. We (...) suggest that recognizing this might help McMahan to answer some unanswered questions to which his own position gives rise. (shrink)

This paper is an exploration of the nature of what is perhaps the most widely recognized justification for inflicting harm on human beings: the appeal to defense (self-defense and other-defense). I develop and defend a rights-based account of the appeal to defense that takes into account whether and to what degree both the aggressor and his potential victim are morally responsible for the relevant threat. However, unlike most extant rights-based accounts, mine is not a forfeiture account. That is, I do (...) not attempt to explain the permissibility of defense in terms of the aggressor’s loss of a right not to be harmed. Instead I appeal directly to the fact that defense in the relevant cases prevents the aggressor from infringing upon the rights of his potential victim. Accordingly, I call my account a “prevention account.”. (shrink)
