Famous quotes containing the words planetary and/or system:

    What is a television apparatus to man, who has only to shut his eyes to see the most inaccessible regions of the seen and the never seen, who has only to imagine in order to pierce through walls and cause all the planetary Baghdads of his dreams to rise from the dust.
    Salvador Dali (1904–1989)

    ... in America ... children are instructed in the virtues of the system they live under, as though history had achieved a happy ending in American civics.
    Mary McCarthy (1912–1989)
