The Allegory of the Cave

Plato, who was a Greek philosopher, mentions the Allegory of the Cave in his work The Republic. It is also known as the "Myth of the Cave". (Wikipedia, np).
This allegory deals with the prisoners "who have been chained since their childhood". (Wikipedia,np). Their bodies and heads were chained in one direction and they were only able to see the wall. Someday there was a huge fire behind the captured people and this fire created a path where various things were "moved along." (Wikipedia, np). These things caused shadows on the wall, which the prisoners were able to see. As a speaking puppet carrier passed by, his voice transformed into "an echo against the wall" (Wikipedia, np) and the prisoners believed that the shadows were able to talk. The captured people started identifying the shapes on the wall, which was the only reality they had. The prisoners started playing a game, by identifying the shapes on the wall. The assumption that a prisoner would not have been chained and would have been able to stand up and turn around and could see the sun, would have caused him blindness, since his eyes weren't able to adjust to the sunlight. The sun, which was the last object, also meant at the same time the enlightenment. The freed person didn't want to return back into the cave but felt forced to do so and free his "bondsmen". (Wikipedia, np).
An interesting aspect of this allegory is, that the prisoners refused to be freed and for the free person, descending to the cave required his eyes to adjust to the darkness again and his eyes weren't able to identify the shadows on the wall anymore.
My understanding of this allegory is, that we are all "slaves" to our habits and it is difficult for us to change our daily lives, because we are too much involved in our routines. Another aspect of this allegory goes with the saying:"Ignorance is bliss."
