    “Polarized light showed the secret architecture of bodies; and when the second-sight of the mind is opened, now one color or form or gesture, and now another, has a pungency, as if a more interior ray had been emitted, disclosing its deep holdings in the frame of things.”
    —Ralph Waldo Emerson (1803–1882)

    “For the gods, though slow to see, see well, whenever a man casting aside worship turns folly.”
    —Sophocles (497–406/5 B.C.)
