Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    Thou shalt not set up Wordsworth, Coleridge, Southey;
    Because the first is crazed beyond all hope,
    The second drunk, the third so quaint and mouthy:
    George Gordon Noel Byron (1788–1824)

    Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.
    Willard Van Orman Quine (b. 1908)
