Famous quotes containing the words special purpose, grades, special and/or purpose:

    An indirect quotation we can usually expect to rate only as better or worse, more or less faithful, and we cannot even hope for a strict standard of more and less; what is involved is evaluation, relative to special purposes, of an essentially dramatic act.
    Willard Van Orman Quine (b. 1908)

    He suggested that there might be men of genius in the lowest grades of life, however permanently humble and illiterate, who take their own view always, or do not pretend to see at all; who are as bottomless even as Walden Pond was thought to be, though they may be dark and muddy.
    Henry David Thoreau (1817–1862)

    Jack: A politician, huh?
    Editor: Oh, county treasurer or something like that.
    Jack: What’s so special about him?
    Editor: They say he’s an honest man.
    Robert Rossen (1908–1966)

    It is not the purpose of literature to purvey news. For news consult the Almanac de Gotha.
    Herman Melville (1819–1891)
