So Glaucon, imagine there were 4 people, they have been living in a cave for as long as they can remember.
There was a fire behind them. People would come to project shapes on the walls in front of them to entertain them. They would make names for all these shapes.
One day, one of the people in the cave got the opportunity to go outside into the real world. She left the cave and went outside.
When she went outside, she learned all this new knowledge, like what the sun was, and trees, and so much more. She decided to go back to the cave to tell all her friends.
When she went back to her friends and told them all about trees, and the sun, they all laughed and called her crazy. They thought that while she was out of the cave, the people did something to her that made her dumb.
come with me!
Now imagine all the games they play. Do you think they would have someone in the cave who is the smartest? Who can name all the shapes the quickest? They would probably think he or she is the "smartest". Right?
