The Allegory of the Cave

The Allegory of the Cave appears in Plato's Republic and compares the effect of education and the lack of it on human nature. It is written as a dialogue between Plato's brother and Socrates, who tells of people that have been chained to the wall of a cave their whole lives. They see shadows projected on the wall from objects passing in front of a fire behind them. Socrates explains that the philosopher is like a prisoner who has escaped the cave and realizes that the shadows on the wall are not the true reality at all.
