Famous quotes containing the word light:
“I always used to suffer a great deal if I let myself get too close to reality since the definitive world of the everyday with its hard edges and harsh light did not have enough resonance to echo the demands I made upon experience. It was as if I never experienced experience as experience. Living never lived up to the expectations I had of it—the Bovary syndrome.”
—Angela Carter (1942–1992)
“When the lamp is shattered,
The light in the dust lies dead;
When the cloud is scattered,
The rainbow’s glory is shed;
When the lute is broken,
Sweet tones are remembered not;
When the lips have spoken,
Loved accents are soon forgot.”
—Percy Bysshe Shelley (1792–1822)
“For light doth seize my brain
With frantic pain.”
—William Blake (1757–1827)
