Famous quotes containing the words dial and/or plan:

    “The television screen, so unlike the movie screen, sharply reduced human beings, revealed them as small, trivial, flat, in two banal dimensions, drained of color. Wasn’t there something reassuring about it!—that human beings were in fact merely images of a kind registered in one another’s eyes and brains, phenomena composed of microscopic flickering dots like atoms. They were atoms—nothing more. A quick switch of the dial and they disappeared and who could lament the loss?”
    —Joyce Carol Oates (b. 1938)

    “Any plan conceived in moderation must fail when the circumstances are set in extremes.”
    —Klemens Wenzel Neponuk Lothar Von, Prince Metternich (1773–1859)
