In Republic IV, Socrates argues that the human soul, like the good city, has three divisions. What are the divisions of the city? What are the corresponding divisions of the soul? Briefly give Socrates’s arguments for the divisions of the soul (beginning at 436a, especially 439b ff.). (What principle does he offer? How does he use this principle to distinguish parts of the soul? Please give arguments to establish all three divisions. When discussing an example, please state what the example is meant to show.) What is justice in the soul? What is the proper relationship of the parts in a just soul?
