Famous quotes containing the word light:

    The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.
    Jean Baudrillard (b. 1929)

    For eighteen hundred years, though perchance I have no right to say it, the New Testament has been written; yet where is the legislator who has wisdom and practical talent enough to avail himself of the light which it sheds on the science of legislation?
    Henry David Thoreau (1817–1862)

    Light, seeking light, doth light of light beguile;
    So ere you find where light in darkness lies,
    Your light grows dark by losing of your eyes.
    William Shakespeare (1564–1616)
