Moral philosophy can be divided into two major fields: metaethics, which concerns the meaning and status of moral language, and normative ethics, which centers on what we ought to do. An ancient controversy in metaethics is that between moral realism, the view that moral language states facts about the world, and moral subjectivism, the view that moral language expresses the attitudes of speakers. Moral language seems to have both the characteristics of fact-stating discourse as well as some of the characteristics of expressions of attitudes. The challenge of metaethics is to reconcile the object-relatedness of realism with the motivational insight of subjectivism. Such a view must hold that valuing is contextual, object-directed, and constrained by biology, psychology, and history. Such a view is demonstrated through an investigation of the concept of intrinsic value.
