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)

    “Do I terrify?—

    The nose, the eye pits, the full set of teeth?
    The sour breath
    Will vanish in a day.”
    —Sylvia Plath (1932–1963)

    “Could Shakespeare give a theory of Shakespeare?”
    —Ralph Waldo Emerson (1803–1882)
