Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    Fruits are acceptable gifts, because they are the flower of commodities, and admit of fantastic values being attached to them. If a man should send to me to come a hundred miles to visit him, and should set before me a basket of fine summer-fruit, I should think there was some proportion between the labor and the reward.
    Ralph Waldo Emerson (1803–1882)

    No theory is good unless it permits, not rest, but the greatest work. No theory is good except on condition that one use it to go on beyond.
    André Gide (1869–1951)
