Book excerpt: We commonly attribute to states and other institutional organizations moral duties and obligations. For example, it is widely held that the state has a moral duty to protect its citizens from external threats and (more contentiously) it is claimed that it ought to positively promote the welfare of its members. When we focus on the surface grammar of such institutional duty-claims, we see that they seem to differ from individual duty-claims only with respect to the subject of the claim. Whereas an institutional duty-claim asserts that an institution (e.g., the state) has a duty to do some action a, an individual duty-claim asserts that a particular individual person has a duty to a. For example, we might claim that parents ought to protect their children, or that a particular person, Doe, ought to take better care of his child. Many scholars have argued or at least assumed that institutions are ultimately just collections of individuals, and hence institutional duty-claims can be analyzed in terms of claims about individuals' duties and obligations. Other scholars have rejected this reductive approach to institutional duty-claims as well as the individualist assumption upon which it is premised--viz., that institutions are nothing "over and above" individuals. Instead, it is argued that at least some institutional organizations are moral agents in their own right which have duties and obligations that are uniquely their own. According to this antireductive holist approach, at least some institutional duty-claims resist being analyzed into claims about individuals' duties and obligations. My aim in this dissertation is to clarify what is meant when we assert that the state (or some other institutional organization) has moral duties, and I do so by entering into dialogue with both the reductive individualist and antireductive holist views.
