 The analysis of concrete cases or examples is methodologically important in the philosophical discussion of supererogation. Unlike other subjects in ethics, like justice or duty, in which there is wide agreement about some core cases, supererogation is a concept the applicability of which is controversial. Unlike the concepts of justice and duty, which have deep roots in both ordinary language and everyday moral judgment, the idea of supererogation is only tenuously anchored in common moral discourse and the concept itself is a theoretical construct. Examples cannot in themselves prove the truth of any of the previously discussed analyses of supererogation, but they can definitely help in revising the various definitions of the concept as well as make a case for one or another of its justifications. Admittedly, some measure of circularity is inevitable in such a method, since the way examples are understood and analyzed is also informed by the definition and the construction of the theoretical concept.
