Constructive Set Theory/aczels Constructive Zermelo-fraenkel

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)

    He set the jug down slowly at his feet
    With trembling care, knowing that most things break;
    Edwin Arlington Robinson (1869–1935)

    Thus the theory of description matters most.
    It is the theory of the word for those
    For whom the word is the making of the world,
    The buzzing world and lisping firmament.
    Wallace Stevens (1879–1955)
