The Myth of the cave

The Fourth Gospel's stark contrast of appearances and reality, true and erroneous opinion, light and darkness, is often seen as a result of Greek and Gnostic influences. But such contrasts are not limited to this Gospel, nor are they a theme of the Greeks alone.

The story of the blind man does, however, ring a bell for anyone who has ever read "The Myth of the Cave" in Plato's Republic. There we find a story of all humanity chained in a darkened cave throughout life. These captives can see nothing but flickering images on a wall—shadows, appearances, illusions—which they take for reality. One prisoner, liberated from the chains, makes the arduous crawl upward to the world of the shining sun. When he returns to the cave with his tales of the new-found source of light and the life and warmth it gives, the prisoners think him crazy. They simply deny his experience. It just can't be. The chains and the amusing images on the wall are reality. Thus his conversion is ridiculed; his invitation is resisted.
