The concept of courage is having the quality or spirit that enables you to face danger or pain without showing fear. A good definition of courage is being brave enough to face danger or embarrassment from doing what you feel is right. In other words, doing what you want to do even if it ruins your reputation. For example: if a man feels it is necessary to stand up for his rights as a man and protest against a civil law but he feels he'll be embarrassed and his reputation will be hurt and he stands up for the right, then he's showing courage.
The story "On The Rainy River" by Tim O"Brien (the narrator) is about a young man trying to decide whether to fight in a war on communism or flee to Canada. He says, "I couldn't make myself be brave. It had nothing to do with morality. Embarrassment, that's all" (O"Brien 208). He also says, "I was a coward. I went to war" (208). This reveals O"Brien's feelings about courage and how he sees it.
If I were in O"Brien's shoes I would have fought in the war just like he did. I would have done this because if I were to live through it then I would have a free ride into college when I got back. Besides I wouldn't have wanted to have to look back on myself fleeing to Canada like a "brave" person would. I would rather be a "coward".
Ultimately, courage was very important in this story because of the problem O"Brien faced; being the fact that he couldn't decide whether or not to fight in the war or flee to Canada.
