The Justification of Associative Duties

People often think that their special relationships with family, friends, comrades and compatriots, can ground moral reasons. Among these reasons, they understand some to be duties - pro tanto requirements that have genuine weight when they conflict with other considerations. In this paper I ask: what is the underlying moral structure of associative duties? I first consider and reject the orthodox Teleological Welfarist account, which first observes that special relationships are fundamental for human well-being, then claims that we cannot have these relationships, if we do not recognise associative duties, before concluding that we should therefore recognise associative duties. I then introduce a nonteleological alternative, grounded in the Appropriate Response approach to ethical theory.
