Famous quotes containing the word heart:
“The heart may think it knows better: the senses know that absence blots people out. We really have no absent friends. The friend becomes a traitor by breaking, however unwillingly or sadly, out of our own zone: a hard judgment is passed on him, for all the pleas of the heart.”
—Elizabeth Bowen (1899–1973)
“Although the stupid, unthinking world may approve what you have done, in your heart you know that, but for your treachery, the boy you loved would be alive today. If anyone is responsible for his death, you killed him, and for that murder you will live and die in the contempt and loathing of your own heart.”
—Karl Brown (1897–1990)
“You would rouse to anger a heart of stone.”
—Sophocles (497–406/5 B.C.)
