I. INTRODUCTION Twenty-five years is roughly the time that has elapsed since the exchange between H. L. A. Hart and Lon Fuller and the subsequent revival in this country of the natural law/positivism debate. During this time, a curious thing has happened to legal positivism. What began as a conceptual theory about the distinction between law and morality has now been turned, at least by some, into a moral theory. According to this theory, the reason we must see law and (...) morality as separate is not because of the logic of our language, but because of the practical implications of holding one or the other of the two traditional views in this area. The natural law theorist, it is said, can connect law and morality only at the cost of investing official directives with undeserved moral authority, thus encouraging obedience where there should be none. The natural law position should therefore be rejected – and the positivist's accepted – on moral grounds. (shrink)
