Equivalence Class Structure

Famous quotes containing the words class and/or structure:

    Sometimes I think that idlers seem to be a special class for whom nothing can be planned, plead as one will with them—their only contribution to the human family is to warm a seat at the common table.
    F. Scott Fitzgerald (1896–1940)

    Who says that fictions only and false hair
    Become a verse? Is there in truth no beauty?
    Is all good structure in a winding stair?
    May no lines pass, except they do their duty
    Not to a true, but painted chair?
    George Herbert (1593–1633)
