Famous quotes containing the words cross and/or section:

    It was mankind that hung on the cross for two thousand years: and a terrible god practiced his cruelty and called it “love.”
    Friedrich Nietzsche (1844–1900)

    ... all my letters are read. I like that. I usually put something in there that I would like the staff to see. If some of the staff are lazy and choose not to read the mail, I usually write on the envelope “Legal Mail.” This way it will surely be read. It’s important that we educate everybody as we go along.
    Jean Gump, U.S. pacifist. As quoted in The Great Divide, book 2, section 10, by Studs Terkel (1988)
