Plato’s cave

Περιγραφή

Once upon a time, Plato, the great ancient philosopher,
told the myth of the cave: deep underground,
people lived inside a cave, having never seen the outside world.
They believed that the cave, and everything they saw
and heard within it, was the entirety of existence.

So what would happen if someone of them managed to get out of the cave and see the sun for the first time in his life?
