Famous quotes containing the words impossible and/or puzzle:
“But can see better there, and laughing there
Pity the giants wallowing on the plain.
...
Pygmies expand in cold impossible air,
Cry fie on the giantshine, poor glory which
Pounds breast-bone punily, screeches, and has
Reached no Alps: or, knows no Alps to reach.”
—Gwendolyn Brooks (b. 1917)
“What are you now? If we could touch one another,
if these our separate entities could come to grips,
clenched like a Chinese puzzle . . . yesterday
I stood in a crowded street that was live with people,
and no one spoke a word, and the morning shone.
Everyone silent, moving. . . . Take my hand. Speak to me.”
—Muriel Rukeyser (1913–1980)
