Plato uses the Allegory of the Cave to demonstrate the flawed existence of human beings who are trapped perceiving shadows rather than true forms of reality. In the cave, people are in the lowest forms of knowledge, but some may be freed and experience a journey through higher forms of knowledge by moving from shadows to reflections to objects to the sun itself. This represents the potential ascent from lower to higher epistemic states and the acquisition of true knowledge and understanding, allowing one to become a philosopher.
