Famous quotes containing the word alternation:

    “The law of nature is alternation for evermore. Each electrical state superinduces the opposite. The soul environs itself with friends, that it may enter into a grander self-acquaintance or solitude; and it goes alone for a season, that it may exalt its conversation or society.”
    —Ralph Waldo Emerson (1803–1882)
