Plato's Cave

What's the truth - can we really know the truth - and where does truth start or end?

And as the picture asks - what truth are we shown?



Imagine prisoners, who have been chained since their childhood deep inside a cave: not only are their limbs immobilized by the chains; their heads are chained in one direction as well so that their gaze is fixed on a wall.

Behind the prisoners is an enormous fire, and between the fire and the prisoners is a raised walkway, along which puppets of various animals, plants, and other things are moved along. The puppets cast shadows on the wall, and the prisoners watch these shadows. When one of the puppet-carriers speaks, an echo against the wall causes the prisoners to believe that the words come from the shadows.
