Philosopher king

According to Plato, a Philosopher king is a ruler who possesses both a love of knowledge, as well as intelligence, reliability, and a willingness to live a simple life. Such are the rulers of his utopian city Kallipolis. For such a community to ever come into being, "philosophers [must] become kings…or those now called kings [must]…genuinely and adequately philosophize" (The Republic, 5.473d).

Plato defined a philosopher firstly as its eponymous occupation: "wisdom-lover". He then distinguishes between one who loves true knowledge (as opposed to more experience or education) by saying that the philosopher is the only person who has access to ideas – the archetypal entities that exist behind all representations of the form (such as Beauty itself as opposed to any one particular instance of beauty). It is next and in support of the idea that philosophers are the best rulers that Plato fashions the Ship of State metaphor, one of his most often cited ideas (along with his allegory of the cave): a "true pilot must of necessity pay attention to the seasons, the heavens, the stars, the winds, and everything proper to the craft if he is really to rule a ship" (The Republic, 6.488d).

Archytas was a Pythagorean philosopher and political leader in the ancient Greek city of Tarentum, in Italy. He was a close friend of Plato, and some scholars assert that he may have been an inspiration for Plato's concept of a philosopher-king.

Dion of Syracuse was a disciple of Plato. He overthrew the tyrant Dionysius II of Syracuse and was installed as leader in the city, only to be made to leave by the Syracusans who were unhappy with his opposition to democratic reforms. He was later re-invited to the city, where he attempted to establish an aristocracy along Platonic lines, but he was assassinated by plotters in the pay of the former tyrant.

Marcus Aurelius was the first prominent example of a philosopher king. His Stoic tome Meditations, written in Greek while on campaign between 170 and 180, is still revered as a literary monument to a philosophy of service and duty, describing how to find and preserve equanimity in the midst of conflict by following nature as a source of guidance and inspiration.
