Why I like the Analogy of the Cave!

I like the Analogy of the Cave because it gives insight into Plato's views on Epistemology and Metaphysics.  Plato's epistemology seems to believe that with effort we can begin to know a form of the truth.  His epistemology seems to lead from his metaphysics that the more you know, you notice that what you thought was truth was just a lesser form of what you know now.  Seemingly since we cannot know everything then would lead to a perfect form.  A form that is not tangible for human knowledge.  These "perfect forms" are the basis of the metaphysics for Plato.
