Famous quotes containing the word zone:

    Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash.
    Louis Aragon (1897–1982)
