Famous quotes containing the word heart:
“One enemy, of many, who knows well
Your heart is luminous
In the watched dark, quivering through locks and caves,
Will pull the thunderbolts
To shut the sun, plunge, mount your darkened keys....”
—Dylan Thomas (1914–1953)
“Half the business is done, when one has gained the heart and the affections of those with whom one is to transact it.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“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)
