Famous quotes containing the word human:
“But ancient insolence is wont to bear an insolence that has its youth among human miseries, sooner or later, when the fixed time of birth is come.”
—Aeschylus (525–456 B.C.)
“I weathered some merry snow-storms, and spent some cheerful winter evenings by my fireside, while the snow whirled wildly without, and even the hooting of the owl was hushed. For many weeks I met no one in my walks but those who came occasionally to cut wood and sled it to the village.... For human society I was obliged to conjure up the former occupants of these woods.”
—Henry David Thoreau (1817–1862)
