That reference to "mere hard cash" is not so smug as it may sound. We are up against the essential deceit of the great majority of orthodox and unorthodox treatments—that the patient can be healed by paying some one to "take away the disease" without involving the patient in either physical or mental exertion. These treatments do not recognise that the disease is a part of the patient—not something which has made unlawful entry into his body. It is nothing more heroic than a state of filth and disrepair into which the patient has allowed his system to fall. The main causes are the patient’s own behaviour, character and environment. None of these is significantly affected by the purchase and consumption of a concoction which may jolt the body into some form of physiological reaction. To many, the financial outlay can be a very real sacrifice, but it does not in any way serve as a substitute for self-discipline, intelligent understanding, and the personal and sustained effort which the patient must be prepared to expend if he is to regain genuine health.
It matters not whether the vendor genuinely believes in the curative effects of his vegetable extract or tissue-food, or whether he is simply a commercial agent with something to sell, the implication that the patient need make no attempt to mend his ways is part of the philosophy of the orthodox medical school. Mis-applying the technical terms from Nature Cure writings may confuse the consumer, but it does not remove the basic fallacy.
