Famous quotes containing the word layer:

    The writer in me can look as far as an African-American woman and stop. Often that writer looks through the African-American woman. Race is a layer of being, but not a culmination.
    Thylias Moss, African American poet. As quoted in the Wall Street Journal (May 12, 1994)
