Final answer:
Plato's three tiers of society, rites of passage, and the desire to understand, explain, and find purpose for human existence represent the three stages of sapiential activity or progression.
Step-by-step explanation:
Plato's notion of three tiers of society - guardians, auxiliaries, and laborers - corresponds with elements of the soul. These three groups work together for the good of the city, just as reason and knowledge work together with discipline to overrule passions that threaten harmony. This progression allows individuals to be just and virtuous.
Rites of passage also depict three distinct stages: separation, liminality, and incorporation. During separation, individuals are removed from their current social identity and prepared for the next stage. In the liminal period, individuals undergo tests or trials to prepare for their new roles. Finally, in the stage of incorporation, individuals return to the community with a new socially recognized status.
The notion of sapiential activity or progression suggests three stages: the desire to understand, explain, and find purpose for human existence. These stages include religion, philosophy, and science, which are closely connected.
