More from Mencken (Mencken)

For it is upon the emotions of the mob, of course, that the whole comedy is played. Theoretically, the mob is the repository of all political wisdom and virtue; actually, it is the ultimate source of all political power. Even the plutocracy cannot make war upon it openly, or forget the least of its weaknesses. The business of keeping it in order must be done discreetly, warily, with delicate technique. In the main that business consists in keeping alive its deep-seated fears—of strange faces, of unfamiliar ideas, of unhackneyed gestures, of untested liberties and responsibilities. The one permanent emotion of the inferior man, as of all the simpler mammals, is fear—fear of the unknown, the complex, the inexplicable. What he wants beyond everything else is security. His instincts incline him toward a society so organized that it will protect him at all hazards, and not only against perils to his hide but also against assaults upon his mind—against the need to grapple with unaccustomed problems, to weigh ideas, to think things out for himself, to scrutinize the platitudes upon which his everyday thinking is based.
