Famous quotes containing the word light:
“Endeavor, as much as you can, to keep company with people above you.... Do not mistake, when I say company above you, and think that I mean with regard to their birth; that is the least consideration; but I mean with regard to their merit, and the light in which the world considers them.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“My paternal grandmother would not light a fire on the Sabbath and piled all Sunday’s washing-up in a bucket, to be dealt with on Monday morning, because the Sabbath was a day of rest—a practice that made my paternal grandfather, the village atheist, as mad as fire. Nevertheless, he willed five quid to the minister, just to be on the safe side.”
—Angela Carter (1940–1992)
““Come unto me,” [Krokowski] was saying, though not in those words, “come unto me, all ye who are weary and heavy-laden”.... He spoke of secret suffering, of shame and sorrow, of the redeeming power of the analytic. He advocated the bringing of light into the unconscious mind.”
—Thomas Mann (1875–1955)
