If one is asked to climb a tree or lift a very heavy weight, there may be reason for saying "I can't," because of lack of ability, strength or practice. For the same reason, difficult "runs" on a piano, perilous feats of balancing or turning in gymnastics, and even a great many simple things that are easy to the accustomed, may be impossible to the unaccustomed without certain practice, and with reference to them it is reasonable to say, "I can't." If, however, one is asked _not_ to climb a tree, or _not_ to lift a weight, or _not_ to perform a "run" on a piano, there is no excuse for saying, "I cannot _not_ do it," for it is as illogical as it is ungrammatical, and as false as any other lie. Applied to mental accomplishment, it is even more illogical and false, because thought is more pliable than muscle. Not being evil is simply _not being evil_, and whoever says, "I cannot _not_ be bad," is a liar. When he is asleep he proves the lie. There are habits-of-desire which seem attractive to perverted taste, that may need a strong counter-suggestion to correct, but there is no habit-of-desire but what can easily be corrected by the right counter-suggestion. For instance, drinking whisky habitually is recognized to be a bad habit of perverted desire, but one habitual drunkard I know of abjured whisky for life on account of having discovered a dead fly in his glass. Sometimes it requires a mania to cure a mania. Dr. H. Holbrook Curtis, the eminent throat-specialist of New York, who has in his care, during grand opera season, millions of dollars' worth of voices, and who makes special study of the mental condition of his patients, once said to me, "The only cure that I know of for dipsomania is religio-mania." This same assertion is frequently made in quite a different way, but to the same effect. Dr. Curtis did not mean by religio-mania religious _appreciation_; neither did he mean by dipsomania, temperate use of stimulants. He referred to the intemperate emotion and the morbid taste. The practice of drinking unduly because of the social temptation of it may be cured by logical suggestion, but a mania may be amenable only to a mania. There is, however, no bad habit but that can be corrected by _some_ means, and as there is some remedy for every separate phase of evil, it should be considered not respectable to say, "I cannot _not_ do"; and, as measure of respectability is the highest social desideratum in the present age, the best weapon to be used against the toleration of evil in one's self or in others is a general protest against it on the score of its being unnecessary and not-respectable.
