This paper deals primarily with theDoctrine of Method(DM) of Kant’sDoctrine of Virtue. First, I present an overview of theDM(1.1) and an explanation of how it is possible to teach virtue (1.2). Second, I address the following issues: Why is aDMnecessary at all (2.1)? How does theDMrelate to what Kant calls casuistry (2.2)? I will argue that wide duties have two essential characteristics: They command the right kind of moral motivation in terms of a moral maxim, and they allow for latitude. (...) The fact that wide duties command the right kind of motivation leads to theDM; the latitude of wide duties, however, leads to casuistry. To unfold this interpretation, it must also be shown that both imperfect and perfect duties are wide duties. (shrink)
