A brave man behaves well in face of danger

I answer that, As stated above (Article 4), fortitude strengthens a man's mind against the greatest danger, which is that of death. Now fortitude is a virtue; and it is essential to virtue ever to tend to good; wherefore it is in order to pursue some good that man does not fly from the danger of death…

Moreover, a brave man behaves well in face of danger of any other kind of death; especially since man may be in danger of any kind of death on account of virtue: thus may a man not fail to attend on a sick friend through fear of deadly infection, or not refuse to undertake a journey with some godly object in view through fear of shipwreck or robbers.
