Famous quotes containing the words list of, puzzles, list and/or impossible:

    Religious literature has eminent examples, and if we run over our private list of poets, critics, philanthropists and philosophers, we shall find them infected with this dropsy and elephantiasis, which we ought to have tapped.
    Ralph Waldo Emerson (1803–1882)

    Woman and fool are two hard things to hit,
    For true no-meaning puzzles more than wit.
    Alexander Pope (1688–1744)

    Weigh what loss your honor may sustain
    If with too credent ear you list his songs,
    Or lose your heart, or your chaste treasure open
    To his unmastered importunity.
    William Shakespeare (1564–1616)

    It is impossible to give a clear account of the world, but art can teach us to reproduce it—just as the world reproduces itself in the course of its eternal gyrations. The primordial sea indefatigably repeats the same words and casts up the same astonished beings on the same sea-shore.
    Albert Camus (1913–1960)
