Famous quotes containing the words field and/or theory:

    “Vigil strange I kept on the field one night;
    When you my son and my comrade dropt at my side that day,
    One look I but gave which your dear eyes return’d with a look I
    shall never forget,
    One touch of your hand to mine O boy, reach’d up as you lay on the ground,”
    —Walt Whitman (1819–1892)

    “... liberal intellectuals ... tend to have a classical theory of politics, in which the state has a monopoly of power; hoping that those in positions of authority may prove to be enlightened men, wielding power justly, they are natural, if cautious, allies of the “establishment.””
    —Susan Sontag (b. 1933)
