The Wikipedia entry on Atlantis is a little sparse on this topic – I’m assuming the Plato made up or embellished an existing myth on an ancient city/state/island and wrote/recorded a Socratic dialog between a bunch of famous philosophers including Socrates to discuss … what, exactly? It appears Atlantis was about to conquer the world, but was impious towards the gods and was destroyed, or something. Was Plato just giving an historical account, or did the philosophers take sides, in some way? I’m wondering mostly if Socrates is very pro-piety in the dialog … you know, in contrast to what he was executed for, or if he and the others are more interestingly philosophical about the explanation and event.
Everyone who believes the story of Atlantis is factual starts with Plato, so I’m wondering if they’re actually missing some significant point, or if there’s no point for them to miss, because Wikipedia says the book in question, isn’t completed by Plato.
