Phase Contrast

Famous quotes containing the words phase and/or contrast:

    The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.
    —W.E.B. (William Edward Burghardt)

    Happiness ain’t a thing in itself—it’s only a contrast with something that ain’t pleasant.... And so, as soon as the novelty is over and the force of the contrast dulled, it ain’t happiness any longer, and you have to get something fresh.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
