It's basically a theoretical conversation of a confused greek "philosopher" talking about an ideal government and society. I think Plato writes it as his mentor Socrates having a discussion with some friends of his on his way to or at a festival or some shyt. In any event once you read it you'll understand why most white people are really confused, especially if that's who they look to and revere as great thinkers, and if that's what they consider to be a classic text of any significance.
it's saving grace is the story Plato has Socrates telling at the end about the warrior who died in a battle and was taken to the afterlife in the underworld to chronicle what he saw and then bring the message back to earth. once you get past alot of the symbolism and nonsense there's a whole lot that can be taken from that story that falls in line with what a good deal of the world believes as far as reincarnation, judgment after death, etc.
to me, that part, which comes at the very end, makes reading thru the rest of that nonsense worth the time.
