Famous quotes containing the words reaction and/or wheel:

    More and more, when faced with the world of men, the only reaction is one of individualism. Man alone is an end unto himself. Everything one tries to do for the common good ends in failure.
    Albert Camus (1913–1960)

    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)
