Famous quotes containing the words empty and/or string:
“The angels yawning in an empty heaven;
Alternate shows of dynamite and rain;
And choosing forced on free will: fire or ice.”
—Philip Larkin (1922–1986)
“The Indian remarked as before, “Must have hard wood to cook moose-meat,” as if that were a maxim, and proceeded to get it. My companion cooked some in California fashion, winding a long string of the meat round a stick and slowly turning it in his hand before the fire. It was very good. But the Indian, not approving of the mode, or because he was not allowed to cook it his own way, would not taste it.”
—Henry David Thoreau (1817–1862)
