Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    a set of crushed and grease-
    impregnated wickerwork;
    on the wicker sofa
    a dirty dog, quite comfy.
    Elizabeth Bishop (1911–1979)

    The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.
    Thomas Henry Huxley (1825–95)
