Famous quotes containing the word heart:
“A crazy man that found a cup,
When all but dead of thirst,
Hardly dared to wet his mouth
Imagining, moon-accursed,
That another mouthful
And his beating heart would burst.”
—William Butler Yeats (1865–1939)
“There can be a fundamental gulf of gracelessness in a human heart which neither our love nor our courage can bridge.”
—Patrick, Mrs. Campbell (1865–1940)
“The hearts of small children are delicate organs. A cruel beginning in this world can twist them into curious shapes. The heart of a hurt child can shrink so that forever afterward it is hard and pitted as the seed of a peach. Or, again, the heart of such a child may fester and swell until it is misery to carry within the body, easily chafed and hurt by the most ordinary things.”
—Carson McCullers (1917–1967)
