Abstract
Stephen Darwall and R. Jay Wallace have independently argued that morality is essentially interpersonal by appealing to necessary connections between morality and responsibility. According to Darwall, morality is grounded in fundamentally second-personal accountability relations. On Wallace's view, a normative moral theory must say that agents’ attitudes towards the moral properties of their actions are reasons for responsibility reactions, which only relational moral theories can do. If either argument succeeds, non-relational moral theories are flawed. I demonstrate that neither argument succeeds. First, I show that grounding morality in accountability relations is implausible. I then argue that the necessary connections that Wallace posits between responsibility and morality exist but need not be explained by moral theories. Finally, drawing on the objections to Darwall and Wallace, I show that, plausibly, no necessary connection between morality and responsibility exists that would rule out any non-relational moral theory. Hence, Darwall and Wallace's strategy does not work.
