  Insofar as power, or interest defined as power, is the concept that defines politics, politics is an autonomous sphere, as Morgenthau says in his sixth principle of realism. It cannot be subordinated to ethics. However, ethics does still play a role in politics. “A man who was nothing but ‘political man’ would be a beast, for he would be completely lacking in moral restraints. A man who was nothing but ‘moral man’ would be a fool, for he would be completely lacking in prudence” (12). Political art requires that these two dimensions of human life, power and morality, be taken into consideration.
