ABSTRACT
Our moral obligations are sometimes collective in nature, that is, they are held by to two or more agents jointly or in common. Agents have a collective moral obligation to do x where x is an option for action that is only collectively available, if they have reason to include that option in their deliberation about their obligations (we-framing the problem), and if each of them has sufficient reason to rank x the highest out of the options available to them. This means that they must have grounds for privileging we-reasoning over reasoning in I-mode. Collective obligations are highly context-dependent and particularly sensitive to shared (or even common) beliefs.
