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)

    To sum up:
    1. The cosmos is a gigantic fly-wheel making 10,000 revolutions a minute.
    2. Man is a sick fly taking a dizzy ride on it.
    3. Religion is the theory that the wheel was designed and set spinning to give him the ride.
    —H.L. (Henry Lewis)
