The Concept of Moral Obligation

The book begins by establishing a set of conceptual distinctions necessary for analysing moral obligation. Zimmerman separates the moral “ought” from prudential, legal, aesthetic, and ideal uses of the term, and then distinguishes obligations that are binding from actions that are merely desirable. He also clarifies the difference between what one ought to do all things considered and what one has reason to do from a particular moral perspective. The later analysis addresses how obligations arise, change, conflict, and cease to bind. It examines whether obligation presupposes ability, how past choices affect present duties, how conditional and prima facie obligations operate, and whether genuine moral dilemmas are possible. The final sections extend the framework to supererogatory action and collective cooperation, presenting a comprehensive conceptual map of moral requirement and responsibility.
