Famous quotes containing the words thin and/or layer:
“And they lie like wedges,
Thick end to thin end and thin end to thick end,
And are a figure of the way the strong
Of mind and strong of arm should fit together,
One thick where one is thin and vice versa.”
—Robert Frost (1874–1963)
“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)
