"Allegory of the Cave" Intro. Paragraph

As stated in the title, Plato’s work is an allegory which is a form of an extended metaphor.  The lesson that was being taught is that we must get out of our cave in order to be fully enlightened.  The people who were chained to the wall represent all of humanity and the chains being our ignorance.  The outside of the cave is the goal that everyone must strive for, it represents information and education.  We have the capability of learning whatever we want.  According to Plato, we have already been taught everything there is to know before being put in the cave, it's just a matter of going out and relearning it.
