Define platos "allegory of the cave" what is the central message? is he describing education alone? where does politics come in? essay prompt pls

Well no one metaphor or allegory defines or helps explain one thing by it's self. (Especially when it comes to philosophers such as Plato).  The easiest way to find the answer is putting it up against different items.  While it does seem to describe education and the art of learning, we can also see that it also describes the attitude towards correction as well.
