‘Normative ethics’ is an enormous field. It is concerned with the articulation and the justification of the fundamental principles that govern the issues of how we should live and what we morally ought to do. Its most general concerns are providing an account of moral evaluation and, possibly, articulating a decision procedure to guide moral action. Though both these aims rely on articulating the correct set of moral principles that govern evaluation and that can also be used in articulating a decision procedure or rule, they are not coextensive. Recent critical work, especially on the part of particularists and virtue ethicists, has generated more pressure to separate clearly the two.
