These features are presented as at least necessary characteristics of the moral domain and asneutral with respect to the contending philosophical views about the fundamental nature andstatus of morality. Moreover, according to Hart, they are ways of articulating the truth in thetheme, recurrent in the history of jurisprudential inquiry, that morality differs from law in thatthe latter only requires
‘external’ behaviour on the part of its subjects, whereas the former places great importance on the quality of an agent’s will (p.173). Rather than go into the
details of these four features individually, I shall suggest two broad concerns triggered by them as a general account of the distinctiveness of moral standards among other practicalstandards.
