Famous quotes containing the words sleep and/or animals:
“Go back to sleep now
Frank, and I may leave a tiny poem
in that brain of yours as my farewell.’”
—Frank O’Hara (1926–1966)
“There is no instant of time when one creature is not being devoured by another. Over all these numerous races of animals man is placed, and his destructive hand spares nothing that lives. He kills to obtain food and he kills to clothe himself; he kills to adorn himself; he kills in order to attack and he kills to defend himself; he kills to instruct himself and he kills to amuse himself; he kills to kill. Proud and terrible king, he wants everything and nothing resists him.”
—Joseph De Maistre (1753–1821)
