Famous quotes containing the words closed and/or system:

    “No other creative field is as closed to those who are not white and male as is the visual arts. After I decided to be an artist, the first thing that I had to believe was that I, a black woman, could penetrate the art scene, and that, further, I could do so without sacrificing one iota of my blackness or my femaleness or my humanity.”
    —Faith Ringgold (b. 1934)

    “... 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)
