Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    Were it good
    To set the exact wealth of all our states
    All at one cast? to set so rich a main
    On the nice hazard of one doubtful hour?
    It were not good.
    William Shakespeare (1564–1616)

    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)
