In Tolkien, power is almost always a test, and most people fail it sincerely.
So why not Aragorn? Because Aragorn’s certainty is not about control. It is about obligation.
Genny Harrison
Aragorn does not claim authority to impose his wil on the world. He accepts authority because he believes the world has a moral order worth serving. His confidence is not self generated. It is inherited, restrained, and constantly oriented outward.
