Famous quotes containing the words constructive, set and/or theory:

    The measure discriminates definitely against products which make up what has been universally considered a program of safe farming. The bill upholds as ideals of American farming the men who grow cotton, corn, rice, swine, tobacco, or wheat and nothing else. These are to be given special favors at the expense of the farmer who has toiled for years to build up a constructive farming enterprise to include a variety of crops and livestock.
    Calvin Coolidge (1872–1933)

    it pleaseth me when I see through the meadows
    The tents and pavilions set up, and great joy have I
    When I see o’er the campana knights armed and horses arrayed.

    And it pleaseth me when the scouts set in flight the folk with
    their goods;
    And it pleaseth me when I see coming together after them an host of
    armed men.
    Bertrans De Born (fl. 12th century)

    Lucretius
    Sings his great theory of natural origins and of wise conduct; Plato
    smiling carves dreams, bright cells
    Of incorruptible wax to hive the Greek honey.
    Robinson Jeffers (1887–1962)
