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)

    Surely, ‘tis one step towards acting well, to think worthily of our nature; and as in common life, the way to make a man honest, is, to suppose him so ... so here, to set some value upon ourselves, enables us to support the character ... of generosity and virtue.
    Laurence Sterne (1713–1768)

    The whole theory of modern education is radically unsound. Fortunately in England, at any rate, education produces no effect whatsoever. If it did, it would prove a serious danger to the upper classes, and probably lead to acts of violence in Grosvenor Square.
    Oscar Wilde (1854–1900)
