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)

    They say it’s worse to be ugly. I think it must only be different. If you’re pretty, you are subject to one set of assaults; if you’re plain you are subject to another.
    Alix Kates Shulman (b. 1932)

    Freud was a hero. He descended to the “Underworld” and met there stark terrors. He carried with him his theory as a Medusa’s head which turned these terrors to stone.
    —R.D. (Ronald David)
