Famous quotes containing the words sleep and/or animals:
“The place became full of a watchful intentness now; for when other things sank brooding to sleep the heath appeared slowly to awake and listen. Every night its Titanic form seemed to await something; but it had waited thus, unmoved, during so many centuries, through the crises of so many things, that it could only be imagined to await one last crisis—the final overthrow.”
—Thomas Hardy (1840–1928)
“You never see animals going through the absurd and often horrible fooleries of magic and religion.... Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat’s meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, quite intelligent enough.”
—Aldous Huxley (1894–1963)
