From page 165 to page 173, Socrates describes to Alcibiades what fierce competition he will have against the Spartan and Achaemenid king if he does not take his development seriously. In those pages, he gives an interesting representation of how Persian princes are raised to become genuine ubermensch, so I'm wondering if we can consider these accounts as historical.
