Fortitude
FOR'TITUDE, noun [Latin fortitudo, from fortis, strong.]
That strength or firmness of mind or soul which enables a person to encounter danger with coolness and courage, or to bear pain or adversity without murmuring, depression or despondency. fortitude is the basis or source of genuine courage or intrepidity in danger, of patience in suffering, of forbearance under injuries, and of magnanimity in all conditions of life. We sometimes confound the effect with the cause, and use fortitude as synonymous with courage or patience; but courage is an active virtue or vice, and patience is the effect of fortitude
Fortitude is the guard and support of the other virtues.
