Famous quotes containing the word lighthouses:

    the ocean, under the pulsation of lighthouses and noise of bell
    buoys,
    advances as usual, looking as if it were not that ocean in which
    dropped things are bound to sink—
    in which if they turn and twist, it is neither with volition nor
    consciousness.
    Marianne Moore (1887–1972)

    The whole fauna of human fantasies, their marine vegetation, drifts and luxuriates in the dimly lit zones of human activity, as though plaiting thick tresses of darkness. Here, too, appear the lighthouses of the mind, with their outward resemblance to less pure symbols. The gateway to mystery swings open at the touch of human weakness and we have entered the realms of darkness. One false step, one slurred syllable together reveal a man’s thoughts.
    Louis Aragon (1897–1982)
