The allegory of the cave is an interesting idea proposed in book seven. The book attempts to explain an idea of education leading to a superior soul. A superior soul is one that receives knowledge through experiences. These experiences are explained by Plato in steps, steps in departure from the cave. While in the cave, the prisoner sees shadows as the realest thing possible. Then the prisoner is allowed to see the statues, he realizes that the statues that cause the statues are realer then the shadows. However, the shadows are still part of the prisoners reality. The prisoner is thrown out of the cave ; he is fascinated by the sun, the light that cause everything he sees. The prisoner sees that the statues were just mere copies of the true world around him. He understands that the statues are only replicas of everything in this world. Book seven states that this is a theoretical process of how knowledge builds the soul. The soul is a primitive idea without knowledge.
