Constructive Set Theory/intuitionistic Zermelo%e2%80%93fraenkel

Famous quotes containing the words constructive, set and/or theory:

    Work is a responsibility most adults assume, a burden at times, a complication, but also a challenge that, like children, requires enormous energy and that holds the potential for qualitative, as well as quantitative, rewards. Isn’t this the only constructive perspective for women who have no choice but to work? And isn’t it a more healthy attitude for women writhing with guilt because they choose to compound the challenges of motherhood with work they enjoy?
    Melinda M. Marshall (20th century)

    And that enquiring man John Synge comes next,
    That dying chose the living world for text
    And never could have rested in the tomb
    But that, long travelling, he had come
    Towards nightfall upon certain set apart
    In a most desolate stony place....
    William Butler Yeats (1865–1939)

    The theory seems to be that so long as a man is a failure he is one of God’s chillun, but that as soon as he has any luck he owes it to the Devil.
    —H.L. (Henry Lewis)
