Abstract

John Finnis's powerfully and deservedly influential modern classic, Natural Law and Natural Rights, expounds a theory of law and morality that is based on a picture of “persons” using practical reason to pursue certain “basic goods.” While devoting much attention to practical reason and to the goods, however, Finnis says little about the nature of personhood. This relative inattention to what “persons” are creates a risk—one that Finnis himself notices—of assuming or importing an inadequate anthropology. This essay suggests that the “new natural law” developed by Finnis suffers in places from the inadvertent adoption of a flawed anthropology—an anthropology under the thrall of modern individualistic commitments. To explain this suspicion, this article discusses three difficulties in his natural law theory: difficulties in accounting for the basic good of friendship, for obligations we owe to others, and for legal authority. These difficulties may seem disconnected, but this article suggests that they may all reflect an inadequate anthropology—one that Finnis does not exactly embrace but that is pervasive today and that in places may affect his theorizing.
