Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    “The truth of the thoughts that are here set forth seems to me unassailable and definitive. I therefore believe myself to have found, on all essential points, the final solution of the problems. And if I am not mistaken in this belief, then the second thing in which the value of this work consists is that it shows how little is achieved when these problems are solved.”
    —Ludwig Wittgenstein (1889–1951)

    “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)
