Famous quotes containing the words earth and/or materials:
“Heaven has its business and earth has its business: those are two separate things. Heaven, that’s the angels’ pasture; they are happy; they don’t have to fret about food and drink. And you can be sure that they have black angels to do the heavy work like laundering the clouds or sweeping the rain and cleaning the sun after a storm, while the white angels sing like nightingales all day long or blow in those little trumpets like they show in the pictures we see in church.”
—Jacques Roumain (1907–1945)
“Though the hen should sit all day, she could lay only one egg, and, besides, would not have picked up materials for another.”
—Henry David Thoreau (1817–1862)
