 … the first ruler of the excellent city must already have thorough cognizance of theoretical philosophy; for he cannot understand anything pertaining to God’s, may He be exalted, governance of the world so as to follow it except from that source. It is clear, in addition, that all of this is impossible unless there is a common religion in the cities that brings together their opinions, beliefs, and actions; that renders their divisions harmonious, linked together, and well ordered; and at that point they will support one another in their actions and assist one another to reach the purpose that is sought after, namely, ultimate happiness. (Book of Religion 27: 113, slightly modified)
