Famous quotes containing the words variable, envelope, return and/or path:

    Walked forth to ease my pain
    Along the shore of silver streaming Thames,
    Whose rutty bank, the which his river hems,
    Was painted all with variable flowers,
    Edmund Spenser (1552?–1599)

    ... 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)

    I believe in the brotherhood of man, all men, but I don’t believe in brotherhood with anybody who doesn’t want brotherhood with me. I believe in treating people right, but I’m not going to waste my time trying to treat somebody right who doesn’t know how to return the treatment.
    Malcolm X (1925–1965)

    Often on bare rocky carries the trail was so indistinct that I repeatedly lost it, but when I walked behind him I observed that he could keep it almost like a hound, and rarely hesitated, or, if he paused a moment on a bare rock, his eye immediately detected some sign which would have escaped me. Frequently we found no path at all at these places, and were to him unaccountably delayed. He would only say it was “ver strange.”
    Henry David Thoreau (1817–1862)
