Plato: The Allegory of the Cave, from The Republic

Plato, the most creative and influential of Socrates` disciples, wrote dialogues, in which he frequently used the figure of Socrates to espouse his own (Plato`s) full-fledged philosophy. In "The Republic," Plato sums up his views in an image of ignorant humanity, trapped in the depths and not even aware of its own limited perspective.
