“But modern medicine does not stop at treating or curing people. It does something even bigger and better—it tries to keep them well. Indeed, the medical profession is the only immolating profession there is—the only profession that is all the time trying, by its efforts in the direction of preventive medicine, to destroy its only source of income—the treatment of disease—by doing all within its power to make disease less and less prevalent. It is continually urging better personal and public hygiene and sanitation. Because medical men understand the stunting effects of ill health on the growing mind and body of the child, they are urging careful medical inspection of schools and school children, and they call for better health conditions in the family, the factory, and the mine, and they denounce without measure unhealthy child labor. Modern medicine tries to banish from the home and school, as nearly as may be, that brutal precept—“He that spareth the rod, hateth his son”— because it knows that the irritable, petulant, stubborn child may be a sick child, or has fools for parents, while the incorrigible boy or girl needs the attention of an expert in nervous and mental diseases rather than the brutality of an impatient, ignorant parent or policeman. “Modern medicine enters the jungle and by proper sanitary rules and regulations makes a deadly, miasmatic swamp a model of cleanliness and healthfulness, as was done in the Panama canal zone, and without which the building of the canal would have been impossible. “Modern medicine seeks to help and to save mankind, not only from physical ills, but from moral ills as well. By the careful study of the influence of inheritance and environment on the development and the conduct of the child, it tries to make his physical inheritance as favorable as possible, and his economic and social environment as helpful as may be, realizing that much of our moral delinquency is due to unjust civic and economic conditions.”
