Rogron was really only head-clerk; he understood nothing of his business as a whole; self-interest, that great motor of the mind, had failed in his case to instruct him. He was often aghast when his sister ordered some article to be sold below cost, foreseeing the end of its fashion; later he admired her idiotically for her cleverness. He reasoned neither ill nor well; he was simply incapable of reasoning at all; but he had the sense to subordinate himself to his sister, and he did so from a consideration that was outside of the business. "She is my elder," he said. Perhaps an existence like his, always solitary, reduced to the satisfaction of mere needs, deprived of money and all pleasures in youth, may explain to physiologists and thinkers the clownish expression of the face, the feebleness of mind, the vacant silliness of the man. His sister had steadily prevented him from marrying, afraid perhaps to lose her power over him, and seeing only a source of expense and injury in some woman who would certainly be younger and undoubtedly less ugly than herself. Silliness has two ways of comporting itself; it talks, or is silent. Silent silliness can be borne; but Rogron's silliness was loquacious. The man had a habit of chattering to his clerks, explaining the minutiae of the business, and ornamenting his talk with those flat jokes which may be called the "chaff" of shopkeeping. Rogron, listened to, of course, by his subordinates and perfectly satisfied with himself, had come at last into possession of a phraseology of his own. This chatterer believed himself an orator. The necessity of explaining to customers what they want, of guessing at their desires, and giving them desires for what they do not want, exercises the tongue of all retail shopkeepers. The petty dealer acquires the faculty of uttering words and sentences in which there is absolutely no meaning, but which have a marked success. He explains to his customers matters of manufacture that they know nothing of; that alone gives him a passing superiority over them; but take him away from his thousand and one explanations about his thousand and one articles, and he is, relatively to thought, like a fish out of water in the sun.
