Famous quotes containing the word light:
“and wife or husband
who does not lock the door of the marriage
against you, finds you
not as unwelcome third in the room, but as
the light of the moon on flesh and hair.”
—Denise Levertov (b. 1923)
“However, the danger in [socially unbalanced relationships] is that the subjection of the woman temporarily calms the man’s jealousy but also renders it more demanding. He ends up making his mistress live like those prisoners on whom light is shone day and night in order for them to be better watched. And things always end in tragedy.”
—Marcel Proust (1871–1922)
“We saw one schoolhouse in our walk, and listened to the sounds which issued from it; but it appeared like a place where the process, not of enlightening, but of obfuscating the mind was going on, and the pupils received only so much light as could penetrate the shadow of the Catholic Church.”
—Henry David Thoreau (1817–1862)
