The shadows of these objects were considered reality to the prisoners, but in actual fact they were just distorted images.
He truly believes that these shadows are complete reality because his “bodily eye” tells him so.
When he is released from the cave, he uses his “mind’s eye” to see the sun, moon, stars, and water.
