In the "The Allegory of The Cave," Plato adopts a dialogue between Socrates and Glaucon which describes his philosophical views on education, which is the difference between the knowledgeable and ignorant. In this dialogue, Socrates passes his opinion to his student Glaucon by using a metaphor. Socrates establishes a cave with a bunch prisoners are chained down on their legs and necks so they won't be able to move and force to look upon the front wall of the cave. The only thing they can do in the cave is to watch the puppet show which it performs behind them by a group of hiding people. In this situation, of course the prisoners couldn't know anything else outside the cave, so they think everything they have been seen, told and learned is absolutely right and true even its not. Although it is just a fictional story, but the theory from it could place in our life especially on education aspect. According to this article, Socrates mentions many times about darkness and light which they represents the inside the cave and outside the cave which also means realm of material and realm of understanding. In the other words, the thing we see from the appearance won't always be what it supposes to be or true, just like the water could be deeper than measuring by your eyes or the shadows of the puppet show which the prisoners seen inside the cave won't be the real. But how we know a thing is true or fate even it can't tell by your eyes? Understand it. Socrates points it out that only when the prisoners escape from the cave they will find out that all the things they seen in the cave were not true, they were all shadows. The reality is outside the cave. Let's assume that every time we learn a new knowledge is like escape from a cave, or escape from ignorant, that means during our whole life, we have many caves to escape, and the only way to get out the cave is education, it is a key to unlock yourself from the chain and stand up to run.
