Linking abstract principles and concrete cases is not always easy. Beginning deductively with ethical theory requires an a priori choice of ethical principles which, when applied, may not take account of the complexity of real problems. But beginning with cases can result in a situationalism in which the normative role of ethical principles is slighted. Casuistry, a case-centered methodology, offers one way to bridge this gap. Casuistry's bottom-up strategy develops policy guidelines out of case analysis, building a middle ground between (...) practice and principle.
