Firmness \Firm"ness\, n.
   The state or quality of being firm.

   Syn: {Firmness}, {Constancy}.

   Usage: Firmness belongs to the will, and constancy to the
          affections and principles; the former prevents us from
          yielding, and the latter from fluctuating. Without
          firmness a man has no character; ``without
          constancy,'' says Addison, ``there is neither love,
          friendship, nor virtue in the world.''
