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

    Euphemisms are not, as many young people think, useless verbiage for that which can and should be said bluntly; they are like secret agents on a delicate mission, they must airily pass by a stinking mess with barely so much as a nod of the head, make their point of constructive criticism and continue on in calm forbearance. Euphemisms are unpleasant truths wearing diplomatic cologne.
    Quentin Crisp (b. 1908)

    Colleges, in like manner, have their indispensable office,—to teach elements. But they can only highly serve us, when they aim not to drill, but to create; when they gather from far every ray of various genius to their hospitable halls, and, by the concentrated fires, set the hearts of their youth on flame.
    Ralph Waldo Emerson (1803–1882)

    The great tragedy of science—the slaying of a beautiful theory by an ugly fact.
    Thomas Henry Huxley (1825–1895)
