Famous quotes containing the word heart:

    If the heart has its reasons, perhaps the body
    Has its own lumbering sort of carnal spirit,
    Felt in the tingling bruises of collision,
    And known to captains as esprit de corps.
    Anthony Hecht (b. 1923)

    The Danube to the Severn gave
    The darken’d heart that beat no more;
    They laid him by the pleasant shore,
    And in the hearing of the wave.
    Alfred Tennyson (1809–1892)

    The soldier’s is the trade:
    In any wind or weather
    He steals the heart of maid
    And man together.

    The lover and his lass
    Beneath the hawthorn lying,
    —A.E. (Alfred Edward)
