Famous quotes containing the words list of, list and/or named:

    I made a list of things I have
    to remember and a list
    of things I want to forget,
    but I see they are the same list.
    Linda Pastan (b. 1932)

    We saw the machinery where murderers are now executed. Seven have been executed. The plan is better than the old one. It is quietly done. Only a few, at the most about thirty or forty, can witness [an execution]. It excites nobody outside of the list permitted to attend. I think the time for capital punishment has passed. I would abolish it. But while it lasts this is the best mode.
    Rutherford Birchard Hayes (1822–1893)

    And then the man whom Sorrow named his friend
    Cried out, Dim sea, hear my most piteous story!
    The sea swept on and cried her old cry still,
    Rolling along in dreams from hill to hill.
    He fled the persecution of her glory....
    William Butler Yeats (1865–1939)
