    There they are at last, Miss Rutledge. The will-o-the-wisps with plagues of fortune. San Francisco, the latest newborn of a great republic.
    Ben Hecht (1893–1964)

    Truth cannot be defined or tested by agreement with ‘the world’; for not only do truths differ for different worlds but the nature of agreement between a world apart from it is notoriously nebulous. Rather—speaking loosely and without trying to answer either Pilate’s question or Tarski’s—a version is to be taken to be true when it offends no unyielding beliefs and none of its own precepts.
    Nelson Goodman (b. 1906)

    Come see the north wind’s masonry.
    Out of an unseen quarry evermore
    Furnished with tile, the fierce artificer
    Curves his white bastions with projected roof
    Ralph Waldo Emerson (1803–1882)

    What, to the American slave, is your Fourth of July? I answer: A day that reveals to him, more than all other days in the year, the gross injustice and cruelty to which he is the constant victim. To him your celebration is a sham.
    Frederick Douglass (c.1817–1895)

    Language fails not because thought fails, but because no verbal symbols can do justice to the fullness and richness of thought. If we are to continue talking about “data” in any other sense than as reflective distinctions, the original datum is always such a qualitative whole.
    John Dewey (1859–1952)
