The hope is springing up in some minds that the entire problem of human regeneration will be much simplified when men shall have learned more fully the nature of their own lives, the nature of the physical world that environs them, and the interaction between this physical world and the spirit of man which is set to subdue it. _Prof. George E. Dawson, The Control of Life through Environment._ We create the evil as well as the good. Nature is impersonal. To an increasing degree _man_ determines. _Carl Kelsey._ The only certain remedy for any disease is man’s own vital power. Today only an exceptional man, almost a genius, learns to modify his habits and his life to his environment and to triumph over his surroundings, his appetites, and the absurd dictates of fashion. _Richard Cole Newton, M.D., How Shall the Destructive Tendencies of Modern Life Be Met and Overcome?_ We have certain inherent capacities as to bodily strength, length of life, etc., but it lies largely with ourselves to adopt a mode of life which may make an actual difference in height, weight, and physical strength and intellectual capacity. _E. H. Richards, Sanitation in Daily Life._ There are two recognized ways of improving the quality of human beings: one by giving them a better heredity--starting them in life with a stronger heart, better digestion, steadier nerves; the other by so combining the factors of daily life that even a weak heart may grow strong, a poor digestion may become good, and frayed nerves gain steadiness. _E. H. Richards, The Art of Right Living._ CHAPTER II FAITH The relation of environment to man’s efficiency is a vital consideration: how far it is responsible for his character, his views, and his health; what special elements in the environment are most potent and what are the most readily controlled, provided sufficient knowledge can be gained of the forces and conditions to be used. To this end home life--in its relations to the child, the adult, and the community--is considered in connection with the effect on the home of the influences outside it, and the reaction of each on the other. These relations and influences are partly physical and material, partly ethical and psychical. The right of the child is protection, and it is the responsibility of the adult--parent, teacher, or state officer--to secure this protection.
