Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    The host, the housekeeper, it is
    who fails you. He had forgotten
    to make room for you at the hearth
    or set a place for you at the table
    or leave the doors unlocked for you.
    Denise Levertov (b. 1923)

    Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.
    Ruth Hubbard (b. 1924)
