A man is afraid because he is afraid. His sympathetic nervous system is gearing him to activity physically. He's in good position to do something about the danger that haunts him. discipline, pride, confidence in leaders, belief in war, aims and a host of other forces press him on toward bravery. Says here, he wants to get out of fighting while his pride makes him want to fight. It is because action is the cure for fear that courage and fear so often go together. Boom. Oh, you're scared? I'm going on the attack.
