Famous quotes containing the word earth:
“When he painted a road, the roadmakers were there in his imagination. When he painted the turned earth of a ploughed field, the gesture of the blade turning the earth was included in his own act. Wherever he looked he saw the labour of existence; and this labour, recognized as such, was what constituted reality for him.”
—John Berger (b. 1926)
“That air would disappear from the whole earth in time, perhaps; but long after his day. He did not know just when it had become so necessary to him, but he had come back to die in exile for the sake of it. Something soft and wild and free, something that whispered to the ear on the pillow, lightened the heart, softly, softly picked the lock, slid the bolts, and released the prisoned spirit of man into the wind, into the blue and gold, into the morning, into the morning!”
—Willa Cather (18731947)
“What angels invented these splendid ornaments, these rich conveniences, this ocean of air above, this ocean of water beneath, this firmament of earth between? this zodiac of lights, this tent of dropping clouds, this striped coat of climates, this fourfold year?”
—Ralph Waldo Emerson (18031882)
