Famous quotes containing the word heart:
“The “sayings” of a community, its proverbs, are its characteristic comment upon life; they imply its history, suggest its attitude toward the world and its way of accepting life. Such an idiom makes the finest language any writer can have; and he can never get it with a notebook. He himself must be able to think and feel in that speech—it is a gift from heart to heart.”
—Willa Cather (1873–1947)
“The heart beats thick,
Big trout muscle out of the dead cold;”
—Ted Hughes (b. 1930)
“he had been alone
Amid the heart of many thousand mists,”
—William Wordsworth (1770–1850)
