Quacks often get social and economic results more agreeable to the patient and more helpful to society than orthodox medicine. "When traitors become numerous enough treason becomes respectable." So when mental hygiene succeeds, it becomes science for the case in question, and for that case orthodox medicine loses its respectability. For the layman there is no safety except in having intelligence enough to know whether his trouble has defied the sincere application of mental treatment, auto-suggestion, and loyalty to the health ideal. Mental hygiene admits the existence of dental cavities, scarlet fever germs, adenoids, cross-eyes, uncleanliness, broken legs, inflamed eyes, overeating. The organic, structural defects which are to be sought by physical examination are all admitted by mental hygienists. They work for an orderly, daily routine and affirm the penalties of its violation. They would even favor going periodically to a physician, provided that we never go to him except when organic or structural disorders may safely be assumed from the fact that cheer and relaxation treatment does not give relief. Unhygienic living and mind cure cannot go together. The mind that tries to deceive itself cannot cure either mind or body. The man who violates the habits of health cannot patch his injuries or conceal the ravages of dissipation by mental hygiene. Here is the great advantage of knowing how to live hygienically, of observing habits of health, and then concerning ourselves not with ourselves, but with conditions of living for all those whose health can be affected by our health, or can affect our health and efficiency.
