In a series of essays published since 1989, Rosen has argued that Islamic law and Moroccan culture are best understood as two interlocking domains and that Muslim judges and jurists employ a mode of judicial reasoning that closely resembles the modes of reasoning found in other domains of Moroccan life. When a qāḍī decides a case, Rosen argues, he seeks to determine the consequences that his judgment will have on the “networks of ties that people possess” by making commonplace assumptions about human nature and the meaning of specific acts. Rosen mentions a Moroccan judge with whom he spoke in 1978 who claimed to be familiār with everyone in the town where he served and thus to be able to distinguish good people from bad on the basis of this knowledge. “All you have to do,” the judge explained to Rosen, “is look at what a person does in order to determine what is in a person's head. If someone is bad it will show up in the way he acts toward other people, and you cannot hide what you do.”
