 The ruling organ in the body is by nature the most perfect and most complete of the organs in itself and in its specific qualification …; beneath it, in turn, are other organs which rule over organs inferior to them …; they rule and are ruled. In the same way, the ruler of the city is the most perfect part of the city in his specific qualification and has the best of everything which anybody else shares with him; beneath him are people who are ruled by him and rule others. (Perfect State V, 15, 5: 235)
