Abstract
There is a long tradition in moral philosophy which maintains that a necessary condition for moral goodness is that one act from a sense of duty. Kant is perhaps the best known and most discussed representative of this view, but one finds others prior to Kant, such as Butler and Price, and Kant's contemporaries, such as Reid, expressing similar ideas. Price, for example writes, ". . . what I have chiefly insisted on, is, that we characterize as virtuous no actions flowing merely from instinctive desires, or from any principle except a regard to virtue itself.'' In this paper, I shall defend a version of this thesis.
