Famous quotes containing the word heart:

    “The Sound of battle fell upon my ear & heart all day yesterday—even after dark the cannon’s insatiate roar continued ...”
    —Elizabeth Blair Lee (1818–?)

    “Night City was like a deranged experiment in Social Darwinism, designed by a bored researcher who kept one thumb permanently on the fast-forward button. Stop hustling and you sank without a trace, but move a little too swiftly and you’d break the fragile surface tension of the black market; either way, you were gone ... though heart or lungs or kidneys might survive in the service of some stranger with New Yen for the clinic tanks.”
    —William Gibson (b. 1948)

    “I saw the spires of Oxford
    As I was passing by,
    The grey spires of Oxford
    Against a pearl-grey sky;
    My heart was with the Oxford men
    Who went abroad to die.”
    —Winifred M. Letts (1887–1972)
