The correlativity of rights and obligations is one of the few stock topics in the basic repertory of English-speaking philosophy th-t is considered suitable for assignment to philosophers specializing in political philosophy. It is a topic perennially discussed, chiefly for reasons that have little to do with its importance: namely, just because it is a recognized topic and because it appears to be a safely tidy one that lends itself readily to being tidied up further by formal or quasi-formal considerations. (...) For my part, I wish more effort went into discussing less tractable subjects like the individuation of rights and their delimitation vis-à-vis one another.What I have to contribute to the subject of correlativity, returning to the scene of my comments on David Lyons’ paper, “The Correlativity of Rights and Duties,” is mainly a stint of annual or biennial repair-work, designed to restore the obvious — the truth that rights do imply obligations and cannot be understood without accepting this implication.
