On the Allegory of the Cave

Anyone who's ever taken a philosophy course or read any books about philosophy is probably familiar with one of the oldest, most famous thought experiments.
Plato, the ancient Greek philosopher, came up with what is known as the "Allegory of the Cave".

Essentially, here's what Plato suggested:
Suppose there's a cave. In this cave, a prisoners have been chained against a wall since childhood; they can't move their limbs, they are only able to look at a blank wall, and these conditions are all that they know.
The entrance of the cave is behind them, as well as some puppeteers. Shadows of the puppets are projected onto the wall from the sunlight, and the prisoners watch these shadows. When a puppeteer speaks, his voice bounces off the wall and it appears that the shadow is talking.
They live their life by looking at the shadows moving about. This is all that they know.

Now, Plato suggested a number of things about these prisoners.
Suppose, for instance, one of the prisoners was unchained and forced to turn around.
Immediately, he will be blinded by the direct sunlight that he has never seen. In his blinded state, when he sees the puppets, they will seem less real than the shadows that he has seen all his life.
After his eyes adjust to the light, the former prisoner would, understandably, want nothing to do with the cave.
He'd be able to experience life as it actually is, rather than by looking at shadows on a wall.

BUT, suppose he goes back to free his friends.
When he walks into the cave, his friends will see his shadow and will just suppose that he's part of their false reality.
Obviously, no form of explanation would be able to convince the prisoners of how lame and pathetic their life is. They would have to get up and turn around and go through exactly the same process that the original person had to go through before they understood.

Now, there's plenty of different interpretations of the allegory.
Platos' interpretation dealt with education.
But we can make our interpretation as well.

In Luke 10:21, Jesus says, "I praise you, Father, Lord of heaven and earth, because you have hidden these things from the wise and learned, and revealed them to little children. Yes, father, for this was your good pleasure."
There's a lot of different philosophies and teachings out there in the world today.
People invent new religions every day.
But when it comes down to it, the vast majority of people are just looking at a wall with shadows dancing across it.
They try to interpret what they see.
They think they understand what's going on.
But in Isaiah 6:9-10, God says, "'Be ever hearing, but never understanding;
be ever seeing but never perceiving.'
Make the heart of this people calloused; make their ears dull and close their eyes. Otherwise they might see with their eyes, hear with their ears, understand with their hearts, and turn and be healed."

We can say that the allegory of the cave is analogous to people's general inability to understand the world as it actually is, to how it was designed, and to how we're supposed to live. And we can try to make people turn around and see life for what it really is.
make sense?
