You know, I'm sure we could start a Republic thread. There are certainly members I can think of who would join us in commenting, if they are engaged and not wandering, looking for trauma... to remember.
A couple thoughts though:
Firstly, +1 Curethan. Time and place - while society hasn't progressed a whole lot since Plato, as Whitehead's quote goes the mass of European philosophy during his time was "a series of footnotes to Plato."
Secondly, there is a much debate between philosophers, first, obviously, to the historical existence of Socrates and, secondly, moreso, to what extent the historical Socrates was actually portrayed as the character of Socrates.
Most academic philosophers I've encountered who deign to have an opinion seem to agree that The Republic represents the first serious break between a consistent individual (Socrates) beforehand and an oratory puppet (Plato) afterwards.
Do not judge my mentor Socrates on Plato's need for him to... posit things.
Lol.
