There are, in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man, whether politician or business man, every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful. The liar is no whit better than the thief, and if his mendacity takes the form of slander, he may be worse than most thieves. It puts a premium upon knavery untruthfully to attack an honest man, or even with hysterical exaggeration to assail a bad man with untruth. An epidemic of indiscriminate assault upon character does not good, but very great harm. The soul of every scoundrel is gladdened whenever an honest man is assailed, or even when a scoundrel is untruthfully assailed. Now, it is easy to twist out of shape what I have just said, easy to affect to misunderstand it, and, if it is slurred over in repetition, not difficult really to misunderstand it. Some persons are sincerely incapable of understanding that to denounce mud-slinging does not mean the indorsement of whitewashing; and both the interested individuals who need whitewashing, and those others who practice mud-slinging, like to encourage such confusion of ideas. One of the chief counts against those who make indiscriminate assault upon men in business or men in public life, is that they invite a reaction which is sure to tell powerfully in favor of the unscrupulous scoundrel who really ought to be attacked, who ought to be exposed, who ought, if possible, to be put in the penitentiary. If Aristides is praised overmuch as just, people get tired of hearing it; and overcensure of the unjust finally and from similar reasons results in their favor.
