firmnes

n. The state or quality of being firm.

Syn. -- Firmness, Constancy. 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.” [ 1913 Webster ]
