Famous quotes containing the words field and/or theory:

    “Never in the field of human conflict was so much owed by so many to so few.”
    —Winston Churchill (1874–1965)

    “By the “mud-sill” theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be—all the better for being blind, that he could not tread out of place, or kick understandingly.... Free labor insists on universal education.”
    —Abraham Lincoln (1809–1865)
