Abstract
H.L.A. Hart’s legal positivism displaces the authority of institutions and emphasizes the independence of personal moral judgment. While such a position has an obvious appeal, we should not fail to acknowledge the extent to which values are articulated within established practices. In this essay, civility and law are offered as examples of practices that embody distinctive values and can properly be understood only by reference to such values. It is suggested that legal positivism is driven by a moral metaphysic wherein abstractly conceived principles confront neutrally described facts. But values cannot, without distortion, be understood in abstraction from the practices and forms of association within which they find expression. The refusal to recognize this fact fosters moral skepticism rather than individual moral responsibility
