Brother of Plato and Glaukon, he is one of the main listener-allies in the dialogue. Beside Glaukon's fiery and excessive theoretical attacks, Adeimantos, as a balancing force, deals with highly practical, cultural, and institutional issues such as society, censorship, poetry, the happiness of the people, how the guardians of the state should live, artistic formation in education, and the permanence of order in the state. By giving critical warnings to Socrates while banishing poets and establishing communal marriage, he ensures the text establishes laws of morality and literature.
A wise Athenian with a noble background like Glaukon, who grew up observing how the city's bards and religious storytellers created manipulation over the public.
A profile of a cool-headed, observant Greek elite. Someone who carries a degree more weight in age or intellectual maturity compared to his brother.
Glaukon
His brother, who comes from the same genes and advocates the practical edge of the same periphery in thought.
Sokrates
The mentor whose moral faculty he loves dearly, yet whose objections and doubts he cleverly conveys.
