Plato begins Book VI describing what the nature of the State's rulers or guardians should consist of. According to Plato, truthfulness, spirit, moderation, gentility, and the ability to grasp the forms are some of the essential qualities of a good and just ruler. "Since those who are able to grasp what is always the same in all respects are philosophers, while those who are not able to do so and who wander among the many things that vary in every sort of way are not philosophers, which of the two should be leaders in the city?"
