The disease is easily acquired. Mr. Smith, a broker, finds himself in an environment of "schemes" and "deals" in which the quality of mercy is strained, and the wind is decidedly not tempered to the shorn lamb. After all, business is business. He shrugs his shoulders and takes his part. But his unexpended fund of native idealism--if, as is most probable, he has his share--seeks its due satisfaction. He cannot use it in business; so he takes it out in a novel or a play where, quite contrary to his observed experience, ordinary people like himself act nobly, with a success that is all the more agreeable for being unexpected. His wife, a woman with strange stirrings about her heart, with motions toward beauty, and desires for a significant life and rich, satisfying experience, exists in day-long pettiness, gossips, frivols, scolds, with money enough to do what she pleases, and nothing vital to do. She also relieves her pent-up idealism in plays or books--in high-wrought, "strong" novels, not in adventures in society such as the kitchen admires, but in stories with violent moral and emotional crises, whose characters, no matter how unlifelike, have "strong" thoughts, and make vital decisions; succeed or fail significantly. Her brother, the head of a wholesale dry-goods firm, listens to the stories the drummers bring home of night life on the road, laughs, says to himself regretfully that the world has to be like that; and then, in logical reaction, demands purity and nothing but aggressive purity in the books of the public library. The hard man goes in for philanthropy (never before so frequently as in America); the one-time "boss" takes to picture-collecting; the railroad wrecker gathers rare editions of the Bible; and tens of thousands of humbler Americans carry their inherited idealism into the necessarily sordid experiences of life in an imperfectly organized country, suppress it for fear of being thought "cranky" or "soft," and then, in their imagination and all that feeds their imagination, give it vent. You may watch the process any evening at the "movies" or the melodrama, on the trolley-car or in the easy chair at home.
