ND now, I said,
let me show in a figure how far our nature is enlightened or
unenlightened: --Behold! human beings living in a underground den,
which has a mouth open towards the light and reaching all along the
den; here they have been from their childhood, and have their legs
and necks chained so that they cannot move, and can only see before
them, being prevented by the chains from turning round their heads.
Above and behind them a fire is blazing at a distance, and between
the fire and the prisoners there is a raised way; and you will see,
if you look, a low wall built along the way, like the screen which
marionette players have in front of them, over which they show the
puppets. I see. And do you see, I said, men passing along the wall
carrying all sorts of vessels, and statues and figures of animals
made of wood and stone and various materials, which appear over the
wall? Some of them are talking, others silent.
