Famous quotes containing the word light:
“I think continually of those who were truly great.
Who, from the womb, remembered the soul’s history
Through corridors of light where the hours are suns,
Endless and singing.”

“As I have known them passionate and fine,
The gold for which they leave the golden line
Of lyric is a golden light divine,
Never the gold of darkness from a mine.”
—Robert Frost (1874–1963)
“It is the essence of truth that it is never excessive. Why should it exaggerate? There is that which should be destroyed and that which should be simply illuminated and studied. How great is the force of benevolent and searching examination! We must not resort to the flame where only light is required.”
—Victor Hugo (1802–1885)
