If we take the generally accepted definition of bravery as a quality which knows not fear, I have never seen a brave man. All men are frightened. The more intelligent they are the more they are frightened. The courageous man is the man who forces himself, in spite of his fear, to carry on. Discipline, pride, self-respect, self-confidence, and the love of glory are attributes which will make a man courageous even when he is afraid.
