Famous quotes containing the words seashell and/or surface:

    A seashell should be the crest of England, not only because it represents a power built on the waves, but also the hard finish of the men. The Englishman is finished like a cowry or a murex.
    Ralph Waldo Emerson (1803–1882)

    Puritanism, in whatever expression, is a poisonous germ. On the surface everything may look strong and vigorous; yet the poison works its way persistently, until the entire fabric is doomed.
    Emma Goldman (1869–1940)
