Chapter IV. HOW WE MAY RECOGNISE WHETHER A MAN HAS IN HIM THE CARDINAL VIRTUE OF STRENGTH NOW we must consider how we may recognise whether a man has in him this virtue of strength, which in Latin is called fortitudo. As a first sign you will observe that he finds all his pleasure and all his delight in being in arms, and in just wars, and in defending all just causes, quarrels, and holy arguments. The second sign is that a man, seeing the"great ill and peril incurred in making such a war, or maintaining such quarrel, should yet not quit his purpose, nor for any labour or travail fear to expose his body to fair fight and strict justice.
