And now, let me show in a figure how far our nature is enlightened or unenlightened:—Behold! human beings living in an underground 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….

They see only their own shadows, or the shadows of one another, which the fire throws on the opposite wall of the cave. To them, the truth would be literally nothing but the shadows of reality.

– Plato, (edited version of) The Republic, 514A, trans. Benjamin Jowett
