Blog Entry 5: the summary of "The Allegory of the Cave"

In the "Allegory of the Cave", Socrates described a story concerns the prisoners who were kept in chains and forced to live in the underground cave since their childhood.  The prisoners became to believe the shadows on the wall which they only could watch in their lifetime is real, because they never saw the reality outside of the world.  After one of them was released from the cave, he found out what he believed before was false.  Moreover, he returned to the cave and tried to explain what he saw to his partners, but they could not recognize their friends.  Socrates wants to use this story to enlighten people that something in the world of sight, we see, hear or believe maybe true or may not, but all we do not know.  Whether it is true or false, the truth only can be proved and seen with an effort by using the world of knowledge.
