Famous quotes containing the word century:
“Evil can be got very easily and exists in quantity: the road to her is very smooth, and she lives near by. But between us and virtue the gods have placed the sweat of our brows; the road to her is long and steep, and it is rough at first; but when a man has reached the top, then she is easy to attain, although before she was hard.”
—Hesiod (c. 8th century B.C.)
