Abstract

This paper has a threefold purpose: to question the adequacy of two familiar proposals for explaining the permissibility of harming others in self-defense, to suggest an alternative explanation, and to answer some objections to this latter explanation. By and large, discussions of the proposals whose adequacy I will question focus on what they imply about the permissibility of self-defense in controversial cases. I will argue here that the proposals themselves contain large and significant theoretical gaps. Accordingly, examining their implications for controversial cases is premature, since they don’t adequately explain permissible self-defense in even the clearest cases—that is, those in which people defend themselves against “culpable attackers”.
