Abstract: Starting from the two opponent views on the failure of the Enlightenment Projects,this paper analyzed A. MacIntyre's doctrine of moral theory.In MacIntyre's opinion,while contemporary emotivism led to incommensurable moral particularity, he Enlightenment Projects did not achieve its purpose for moral universality, because their premises were incommensurable,either. he difference between emotivists and enlightenment thinkers was that the latter stick to dealing with moral disagreenment in a rational way,but the former had given up.MacIntyre was not satisfied with such two attitudes and planned to discuss it in a traditional rational way.However,his plan encountered lots of difficulties.My viewpoint is that only by enough rational discourse,can we put moral university and moral particularity to rights

Key words: Enlightenment Project, incommensurable, moral university, moral particularity
