Fraenkel Set Theory

Famous quotes containing the words set and/or theory:

    The eyes that drew from me such fervent praise,
    The arms and hands and feet and countenance
    Which made me a stranger in my own romance
    And set me apart from the well-trodden ways;
    Petrarch (1304–1374)

    There never comes a point where a theory can be said to be true. The most that one can claim for any theory is that it has shared the successes of all its rivals and that it has passed at least one test which they have failed.
    —A.J. (Alfred Jules)
