Famous quotes containing the word heart:

    “Tell me where is fancy bred,
    Or in the heart or in the head?
    How begot, how nourished?
    Reply, reply.
    It is engendered in the eyes,
    With gazing fed, and fancy dies
    In the cradle where it lies.
    Let us all ring fancy’s knell.
    I’ll begin it. Ding, dong, bell.”
    —William Shakespeare (1564–1616)

    “They didn’t know
    how
    my heart woke
    to a range and measure
    of song
    I hadn’t known.”
    —Hilda Doolittle (1886–1961)

    “Who ere shee bee,
    That not impossible shee
    That shall command my heart and mee;”
    —Richard Crashaw (1613?–1649)
