KIE: Explorations of bioethical issues frequently raise the question of an entity's "moral standing," or its right to moral consideration by rational agents. Many contemporary philosophers subscribe to Leonard Nelson's view that only beings that have interests have moral standing. Kuhse attempts to define interests and to delineate the kind of respect owed those that have them. Drawing on the ideas of Joel Feinberg, Peter Singer, Kenneth Goodpaster, Michael Tooley, Tom Regan, and others, she debates the "experience model" versus the "desire model" of interests, both of which have been favored in turn by utilitarians. Kuhse draws attention to difficulties that each model creates for ethical discussions on topics such as the killing of normal adults, nonhuman animals, human fetuses, and handicapped infants. She concludes that there are still problems in defining what interests are and what role they should play in moral deliberations.
