All warfare is merely a contest. In any struggle you see the clashing of will and will, of force against force, of brain against brain. For the impersonal reader it is this contest which has a never-ending interest. A neutral is just as keenly entertained as the playgoer who sits watching the swaying fortunes of the hero in the struggle of the drama. No human being endowed with sympathetic interest, who himself has had to contend with difficulties, fails to be moved by the success or disaster of the contestants in a struggle of which the spectator has no part or lot. If this were not so, neutral newspapers would cease to chronicle the wars of other nations, novels would cease to be published, and plays to be produced. Human nature, then, being what it is, man loves to watch his fellow-man fighting, struggling against men or fate or circumstances. The harder the fight and the nearer he is to losing, so much the more is the spectator thrilled. This instinct is developed most clearly in youth: hence juvenile fiction is one mass of struggles, adventures, and narrow escapes. But the instinct never dies, and how few of us can resist the temptation to read the exciting experiences of some entirely fictional character who rushes from one perilous situation to another? Is there a human being who, going along the street, would not stop to watch a burglar being chased over roofs and chimney-pots by police? If you have once become interested in a certain trial at the law courts, are you not eager to know whether the prisoner has been acquitted or convicted? You despise him for his character, yet you are fascinated by his adventures, his struggles, his share in the particular drama, his fight against heavy odds; and, contrary to your own inherent sense of justice, you almost hope he will be acquitted. In a word, then, we delight in having before us the adventures of our fellow humanity, partly for the exciting pleasure which these arouse in us, but partly also because they make us wonder what we should have done in a similar set of circumstances. In such vital, critical moments should we have played the hero, or should we have fallen somehow a little short?
