Famous quotes containing the words emergency and/or light:

    War-making is one of the few activities that people are not supposed to view “realistically”; that is, with an eye to expense and practical outcome. In all-out war, expenditure is all-out, unprudent—war being defined as an emergency in which no sacrifice is excessive.
    Susan Sontag (b. 1933)

    And for tired eyes every light is too bright, and for tired lips every breath too heavy, and for tired ears every word too much.
    Georg Büchner (1813–1837)
