The Letter of Aristeas, a fascinating text from the Hellenistic period, gives us some food for thought on just that. It recounts the story of how the Septuagint, the Greek translation of the Hebrew Bible, came to be. But tucked within that narrative are some profound questions about kingship and what qualities truly make for a ruler who serves the people well.

So, picture this: a king, impressed by the wisdom of his advisors, decides to pick their brains a bit more. He poses a question, almost like a philosophical riddle: "What is best for the people? A commoner turned king, or someone born into royalty?"

The answer? It's surprisingly simple, and yet incredibly profound: "He who is best by nature."

But what does that mean?

The advisor goes on to elaborate. You see, kings born into royal families, accustomed to privilege and power, can often become harsh and unyielding towards their subjects. They might lose touch with the struggles of everyday life, ruling from an ivory tower. It's a risk inherent in inherited power.

But here’s the kicker: the advisor suggests that those who rise from the ranks of commoners can be even worse. Someone who has known hardship, who has tasted poverty and injustice... you might expect them to be more compassionate. Not necessarily.

According to this advisor in the Letter of Aristeas, those who have clawed their way to the top, who have experienced suffering firsthand, sometimes become the most cruel and tyrannical rulers of all. Having finally attained power, they might be determined to hold onto it at any cost, perhaps even inflicting upon others the very pain they once endured. They might overcompensate, becoming even more ruthless than those born to rule.

It’s a sobering thought, isn't it? That the experience of suffering doesn't automatically lead to empathy or justice. That power, regardless of its origin, can corrupt.

So, what's the takeaway? The Letter of Aristeas seems to be suggesting that true leadership isn’t about birthright or background. It’s about something deeper – an inherent quality of character. It’s about a natural inclination towards justice, compassion, and the well-being of the people. It’s about being "best by nature."

But what is that nature, exactly? Is it something you're born with, or something you cultivate? That, perhaps, is a question for another day. But the Letter of Aristeas certainly gives us plenty to ponder about the true nature of leadership, and what we should be looking for in those who govern us.
