Famous quotes containing the words sleep and/or animals:
“Ah! gentle may I lay me down, and gentle rest my head,
And gentle sleep the sleep of death, and gentle hear the voice
Of Him that walketh in the garden in the evening time!””
—William Blake (1757–1827)
“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)
