There is nothing strange about fear: no matter in what guise it presents itself it is something with which we are all so familiar that when a man appears who is without it we are at once enslaved by him.
If we take the generally accepted definition of bravery as a quality which knows no fear, I have never seen a brave man. All men are frightened. The more intelligent they are, the more they are frightened.
There is the fear that we shan't prove worthy in the eyes of someone who knows us at least as well as we know ourselves. That is the fear of God. And there is the fear of Man --fear that men won't understand us and we shall be cut of from them.
The hero and the coward both feel the same thing, but the hero uses his fear, projects it onto his opponent, while the coward runs. It's the same thing, fear, but it's what you do with it that matters.
