Plato was a pupil under Socrates. During his studies, Plato wrote the Dialogues, which are a collection of Socrates' teachings. One of the parables included in the Dialogues is "The Allegory of the Cave". "The Allegory..." symbolizes man's struggle to reach understanding and enlightenment.

They could not possibly comprehend another dimension without beholding it themselves; therefore, they label the enlightened man mad. This story explains Plato's theory on government. Plato felt the educated (the escaped prisoner) and the uneducated (the prisoners still in the cave) would both not make good leaders of the government.
