Famous quotes containing the words system and/or needle:

    Exploitation and oppression is not a matter of race. It is the system, the apparatus of world-wide brigandage called imperialism, which made the Powers behave the way they did. I have no illusions on this score, nor do I believe that any Asian nation or African nation, in the same state of dominance, and with the same system of colonial profit-amassing and plunder, would have behaved otherwise.
    Han Suyin (b. 1917)

    I am obnoxious to each carping tongue
    Who says my hand a needle better fits,
    A poet’s pen, all scorn, I should thus wrong;
    For such despite they cast on female wits:
    If what I do prove well, it won’t advance,
    They’ll say it’s stolen, or else it was by chance.
    Anne Bradstreet (c. 1612–1672)
