Hart–Fuller debate

The Hart–Fuller debate is an exchange between the American law professor Lon L. Fuller and his English counterpart H. L. A. Hart, published in the Harvard Law Review in 1958 on morality and law, which demonstrated the divide between the positivist and natural law philosophy. Hart took the positivist view in arguing that morality and law were separate. Fuller's reply argued for morality as the source of law's binding power.
