Famous quotes containing the word heart:

    The heart is forever inexperienced.
    Henry David Thoreau (1817–1862)

    The eye of man hath not heard, the ear of man hath not seen, man’s hand is not able to taste, his tongue to conceive, nor his heart to report what my dream was!
    William Shakespeare (1564–1616)

    In every unbeliever’s heart there is an uneasy feeling that, after all, he may awake after death and find himself immortal. This is his punishment for his unbelief. This is the agnostic’s Hell.
    —H.L. (Henry Lewis)
