I am amused, I said, at your fear of the world, which makes you guard against the appliance of insisting upon useless studies; and I quite admit the difficulty of believing that in every man there is an eye of the soul which, when by other pursuits lost and dimmed, is by there purified and re–illuminated and is more precious for then ten thousand bodily eye, for by it alone is truth seen.
— Socrates to Glaucon in Plato’s Republic Book VII
