Famous quotes containing the word wheel:

    The word “revolution” itself has become not only a dead relic of Leftism, but a key to the deadendedness of male politics: the “revolution” of a wheel which returns in the end to the same place; the “revolving door” of a politics which has “liberated” women only to use them, and only within the limits of male tolerance.
    Adrienne Rich (b. 1929)

    Having a wheel and four legs of its own
    Has never availed the cumbersome grindstone
    To get it anywhere that I can see.
    Robert Frost (1874–1963)
