Strengths

• Everyone has moral values

  • e/g many have the intuition that killing can sometimes be justified, for example, in war or in self-defence, whereas murder cannot
• It overcomes some of the problems of ethical naturalism 


  • namely the problem that there seems to be different agreement as to what the 'facts' of ethics are
  • they differ for each of the normative ethical theories
• Realistic in admitting that moral intuition is not perfect 


  • explains why we have moral disagreements in our moral intuitions
  • Ross: where there are such disagreements this is because people's thinking about conflicting prima facie duties is not clear or deep enough
