Famous quotes containing the word defects:

    We often make use of envenomed praise, that reveals on the rebound, as it were, defects in those praised which we dare not expose any other way.
    François, Duc De La Rochefoucauld (1613–1680)

    The machine is impersonal, it takes the pride away from a piece of work, the individual merits and defects that go along with all work that is not done by a machine—which is to say, its little bit of humanity.
    Friedrich Nietzsche (1844–1900)

    One of our defects as a nation is a tendency to use what have been called “weasel words.” When a weasel sucks eggs the meat is sucked out of the egg. If you use a “weasel word” after another there is nothing left of the other.
    Theodore Roosevelt (1858–1919)
