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)

    I do not set my life at a pin’s fee,
    And for my soul, what can it do to that,
    Being a thing immortal as itself?
    William Shakespeare (1564–1616)

    The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.
    Charles Lamb (1775–1834)
