The story of the cave has nothing to do with it being a metaphor about education. simple shallow thinking is all that can conclude that. its about knowledge beyond this world and the attempt by someone who has surpassed the idiocy of this world that keeps the majority in chains and darkness going back into that darkness to try to tell others to look so they too can see the way out. And is killed for his caring to try. but the arrogance in this world never ends so you get entire conflagurations and diatribes inventing oh its about this. Once you know what socrates found out you will laugh at your conclusions about this story.
