Read the passage from "Allegory of the Cave." Socrates: And now, let me show in a figure how far our nature is enlightened or unenlightened: – Behold! human beings living in a underground den, which has a mouth open towards the light and reaching all along the den; here they have been from their childhood, and have their legs and necks chained so that they cannot move, and can only see before them, being prevented by the chains from turning round their heads. Above and behind them a fire is blazing at a distance, and between the fire and the prisoners there is a raised way; and you will see, if you look, a low wall built along the way, like the screen which marionette players have in front of them, over which they show the puppets. What is the purpose of describing human beings as living in an underground den? to show that many people live their lives in terrible physical conditions to use imagery to suggest that people are trapped by their perceptions and prevented from understanding reality to show that people depend on others like the players to describe reality to use imagery to show that people must change their governments to escape their misunderstanding of reality
