Famous quotes containing the word light:
“For it is wretchedness that endures, shedding its cancerous light on all it approaches:
Words spoken in the heat of passion, that might have been retracted in good time,
All good intentions, all that was arguable.”
—John Ashbery (b. 1927)
“If with light head erect I sing,
Though all the muses lend their force,
From my poor love of anything,
The verse is weak and shallow as its source.
But if with bended neck I grope,
Listening behind me for my wit,
With faith superior to hope,
More anxious to keep back than forward it,”
—Henry David Thoreau (1817–1862)
“But misery still delights to trace
Its ‘semblance in another’s case.
No voice divine the storm allay’d,
No light propitious shone;
When, snatch’d from all effectual aid,
We perish’d, each alone:
But I beneath a rougher sea,
And whelm’d in deeper gulphs than he.”
—William Cowper (1731–1800)
