If it is common for men to become angry at ego-injury, there are in this world, as its leaven of reform, noble spirits who become angry at the wrongs of others. The world owes its progress to those whose anger, sustained and intellectualized, becomes the power behind reform; to those like Abraham Lincoln, who vowed to destroy slavery because he saw a slave sold down the river; to the Pinels, outraged by the treatment of the insane; to the sturdy "Indignant Citizen," who writes to newspapers about what "is none of his business," but who is too angry to keep still, and whose anger makes public opinion. Whether anger is useful or not depends upon its cause and the methods it employs. Righteous anger, whether against one's own wrongs or the wrongs of others, is the hall-mark of the brave and noble spirit; mean, egoistic anger is a great world danger, born of prejudice and egoism. A violent-tempered child may be such because he is outraged by wrong; if so, teach him control but do not tell him in modern wishy-washy fashion that "one must never get angry." Control it, intellectualize it, do not permit it to destroy effectiveness, as it is prone to do; but it cannot be eliminated without endangering personality. Fear and anger have this in common: whenever the controlling energy of the mind goes, as in illness, fatigue or early mental disease, they become more prominent and uncontrolled. This cannot be overemphasized. When a man (or woman) finds himself continually getting apprehensive and irritable, then it is the time to ask, "What's the matter with me," and to get expert opinion on the subject. These two emotions are in more need of rationalizing and intelligent control than the other emotions, for they are more explosive. Certainly of anger it is truly said that "He who is master of himself is greater than he who taketh a city." The angry man is disliked, he arouses unpleasant feelings, he is unpopular and a nuisance and a danger in the view of his fellows. The underlying idea underneath courtesy and social regulations is to avoid anger and humiliation. Controversial subjects are avoided, and one must not brag or display concern because these things cause anger and disgust. Politeness and tact are essential to turn away wrath, to avoid that ego injury that brings anger.
