Famous quotes containing the words strings and/or closed:

    Until, accustomed to disappointments, you can let yourself rule and be ruled by these strings or emanations that connect everything together, you haven’t fully exorcised the demon of doubt that sets you in motion like a rocking horse that cannot stop rocking.
    John Ashbery (b. 1927)

    Night hath closed all in her cloak,
    Twinkling stars love-thoughts provoke,
    Danger hence good care doth keep,
    Jealousy itself doth sleep;
    Sir Philip Sidney (1554–1586)
