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)

    John Brown of Ossawattamie
    Who died to set Abstraction free
    Stole Washington’s gold-handled sword
    Less for the gold than for the Lord....
    Allen Tate (1899–1979)

    The theory of truth is a series of truisms.
    —J.L. (John Langshaw)
