Another example is where there is one and only one factor that we can control, and so interest centres upon this, and we regard it as “the cause” of things going one way or another. Thus, if a baby is sick and needs a certain kind of food we may say that the getting or not getting this food is the cause of its living or dying, although its natural vitality, its previous nurture, the character of the disease, and many other conditions enter. This might plausibly be given as a reason for ascribing drunkenness to the saloon; that is, it might be said that the other causes, such as moral weakness, discouragement, lack of better recreation, and the like, were obscure and hard to get at, while the saloon is something that we can abolish. Now what I wish to say is that personal and social degeneration is not ordinarily due to a wholly exceptional factor breaking in upon a sound process, nor is it often the case that all the factors but one are beyond our reach. Usually many conditions of a more or less unwholesome tendency co-operate, and usually all of these are directly or indirectly within our power to amend. The social process has a degenerate side that is an organic part of it, and tends to break out wherever the better influences are relaxed; and it has also a constructive energy that may be applied wherever we see fit. The man who takes to drink is never morally and physically sound, and it is within our power not only to abolish the saloon but to work upon the economic misery, the bad heredity, and other factors that are of equal importance. To attack one of these conditions and not the others might result in a measure of success, but it would be like the success an army may gain by piercing the enemy’s line at only one point; an attempt to advance farther at this point would be exposed to flank attacks by the enemy on each side. If we repress degenerate factors at but one point they are pretty sure to appear at others, and the only hope of permanent conquest lies in an advance all along the line. Recently the people of a neighboring city became alarmed at the growth of juvenile crime, and a leading social worker did me the honor to ask my opinion about the matter. He said that the chief of police laid it to idleness; Father L. of the Catholic Charities to unsupervised recreation; Mr. M. of the Boy Scouts to lack of recreation facilities, and Mr. E. of the Boys’ Farm to wrong conditions in the home.
