In this essay I sketch some vices of virtue ethics, draw on inference about the philosophical source of the vices, and conclude with a recommendation concerning future efforts in moral theory construction. The source of the vices, I argue, lies in a mononomic or single-principle strategy within normative theory construction, a reductionist conceptual scheme which distorts certain integral aspects of our moral experience. My recommendation is that this strategy be abandoned, for the moral field is not unitary -- mononomic methods (...) are not the best tools for moral theorists. (shrink)
