Until philosophers are kings, or the kings and princes of this world have the spirit and power of philosophy, and political greatness and wisdom meet in one, and those commoner natures who pursue either to the exclusion of the other are compelled to stand aside, cities will never have rest from their evils - no, nor the human race, as I believe - and then only will this our State have a possibility of life and behold the light of day.
PlatoThe form of law which I propose would be as follows: In a state which is desirous of being saved from the greatest of all plagues-not faction, but rather distraction-there should exist among the citizens neither extreme poverty nor, again, excessive wealth, for both are productive of great evil . . . Now the legislator should determine what is to be the limit of poverty or of wealth.
