Famous quotes containing the words cross and/or section:
“Flood-tide below me! I see you face to face!
Clouds of the west—sun there half an hour
high—I see you also face to face.
Crowds of men and women attired in the usual costumes, how curious you are to me!
On the ferry-boats the hundreds and hundreds that cross, returning
home, are more curious to me than you suppose,
And you that shall cross from shore to shore years hence are more to me, and more in my meditations, than you might suppose.”
—Walt Whitman (1819–1892)
“The demonstrations are always early in the morning, at six o’clock. It’s wonderful, because I’m not doing anything at six anyway, so why not demonstrate?... When you’ve written to your president, to your congressman, to your senator and nothing, nothing has come of it, you take to the streets.”
—Erica Bouza, U.S. jewelry designer and social activist. As quoted in The Great Divide, book 2, section 7, by Studs Terkel (1988)
