One form of servility consists in a slavish attitude — of the kind incompatible with self-respecting manliness — toward any person who is powerful by reason of his office or position. Servility may be shown by a public servant toward the profiteering head of a large corporation, or toward the anti-American head of a big labor organization. It may also be shown in peculiarly noxious and un-American form by confounding the President or any other official with the country and shrieking “stand by the President” without regard to whether, by so acting, we do or do not stand by the country.
