There are but two alternatives left, an action or an explosion, for activity can no more be confined than steam in an engine. If the explosion has occurred, it has resulted from successful repression. The stopper, "Don't," has been inserted in the last opening through which the nervous force could expend itself, and after a moment of dangerous calm, the inevitable occurs, and the happiness and peace of the entire home is for the time destroyed. The result is just as sure as that of confining an expanding gas, while its disaster is wrought in the mental and moral as well as the physical realms. Fortunately again for the well-being of the child, it is difficult to secure the last outlet, so fertile is his busy brain. But without the explosion, the results that come to a child from a policy of repression are very serious. Briefly stated, they are first, irritability and nervousness. The refinement of cruelty is dealt to a little child, compelled by superior force to act contrary to God's law for him and "Keep quiet." Activity which should normally be expended, when confined, reacts upon the cells of the body so that soon there are physical reasons beyond the child's control for his nervousness and crossness. Second, Friction, in which defiance and stubbornness appear. The severest test which could be imposed upon adults would be a constant and apparently arbitrary thwarting of their desires. Is it to be wondered at that a little, unreasoning life which hears "don't" by the scores of times from morning till night, grows rebellious, vindictive and obstinate? Third, Unhappiness and a sense of alienation. Sympathy between two persons is impossible when they are at cross purposes, and happiness which is God's gift to childhood can never be realized when souls are out of touch. Further, discouragement and consequent loss of incentive to effort must inevitably overwhelm a little life that never does anything right. Fourth, weakened will and character. This is the most serious result of all. One of the great principles already stated makes it clear that development can come only through the activity of the individual himself. If the child is constantly withheld from doing by the word "don't," he can not reach the fullest development of character. Furthermore, character is not built negatively but positively. A building can never be erected by merely keeping out of it all unworthy material. There must be an actual putting together of brick and mortar, and the great truth is evident that whenever a place is filled by the good, the bad is in that very act kept out, whether in buildings or character. The motive back of many a "don't" is worthy, and often there may be no alternative but to instantly check an action, but for the effect on character building there is a more excellent way than repression. It lies in the expression suggested in the law of activity, but expression under direction.
