Perhaps it is too much to expect that a sturdy plant of belief should have grown since the days of Edwin Chadwick and Benjamin Ward Richardson (1830-50), less than a century ago, when there were perhaps not a dozen men and women who believed that man had any appreciable control over his own health. This early school of sanitarians endeavored to “get behind fate, to the causes of sickness.” The modern socionomist is, by a study of the mental conditions of communities, endeavoring to get behind the causes of poverty and consequent suffering to the reasons for _fatal indifference to dirt_. It is well recognized that in severe sicknesses of many kinds the will to get well is more powerful than drugs, that something which we call nerve force acting upon the physical machine sends a vital current through the arteries, coerces the heart to renewed pumping action, and life comes again to the blanched cheek and glazing eye. This more often happens by a mental stimulus than by any medicine. In like manner the improvement of the body’s shell, the home, like that of the soul’s shell, the body, comes more often from an inward impulse than from outward coercion. Appeal to the loving but listless parent will reach the heart quickest through love for the child. Therefore stress should be laid on the child, its habits, its surroundings, its ideals. By ideals is meant the very real stimulus to action coming from within. Action must come through the material things which ideals control and through which they express themselves. Certain notions which have crept into popular currency need to be corrected before the individual can free himself from bondage sufficiently to attempt constructive advance and improvement. Only a small percentage of adults obtain the full efficiency from the human machine--the only means they have of living, working, enjoying. They permit themselves to stand and walk badly, they breathe with only a portion of their lungs, and so fail to furnish the blood stream with oxygen. They dress unhygienically. They eat wrongly. They exercise little. In short, they subject their bodies to abusive treatment which would ruin any machine. Because retribution does not instantly follow infraction of Nature’s laws, they become callous and unbelieving. Economy and efficiency in human time and strength is one of the lessons to be taught the young people, so that they may not waste their patrimony. The youth feels as rich in his fifty years to come as he does with a legacy of $50,000 in the bank. The years, however, can yield only small variations from the established rate of interest. The human machine can manufacture only a limited amount of energy. It remains to utilize that quantity to the best advantage. This can be done only by having a purpose in life strong enough to resist alluring temptations to fritter away both time and strength.
