Reverse Mathematics/%cf%89-models and %ce%b2-models

Famous quotes containing the words reverse and/or mathematics:

    We came home from the ridotto so late, or rather so early, that it was not possible for me to write. Indeed we did not go ... till past eleven o’clock: but nobody does. A terrible reverse of the order of nature! We sleep with the sun, and wake with the moon.
    Frances Burney (1752–1840)

    The three main medieval points of view regarding universals are designated by historians as realism, conceptualism, and nominalism. Essentially these same three doctrines reappear in twentieth-century surveys of the philosophy of mathematics under the new names logicism, intuitionism, and formalism.
    Willard Van Orman Quine (b. 1908)
