The easiest period in a crisis situation is actually the battle itself. The most difficult is the period of indecision -- whether to fight or run away. And the most dangerous period is the aftermath. It is then, with all his resources spent and his guard down, that an individual must watch out for dulled reactions and faulty judgment.
The wise man does not expose himself needlessly to danger, since there are few things for which he cares sufficiently; but he is willing, in great crises, to give even his life -- knowing that under certain conditions it is not worthwhile to live.
