Firmness

Part of speech: noun (n.)

The state or quality of being firm.

Synonyms: 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."
