This section is from the "Nature Cure: Philosophy and Practice Based on the Unity of Disease and Cure" book, by Henry Lindlahr.
In our critical analysis of "Old School" methods we found that by far the greater part of all chronic ailments is due to drugging and to surgery. People commence doctoring for little troubles, which are aggravated by every dose of medicine and every surgical operation until they end in big troubles.
Is it marvelous that such patients improve and that many are cured when they are weaned from drugs and the knife?
Metaphysical healers unwittingly do their best and most beneficial work because they induce their followers not to suppress acute diseases and healing crises by drugs and surgical operations, thus allowing them to run their natural course in harmony with the fundamental law of Nature Cure, which states that every acute disease is the result of a cleansing and healing effort of Nature. People will refrain from the suppressive drug treatment under the influence of metaphysical teachings, which appeal to the miracle-loving element in their nature, when they cannot be convinced by common sense Nature Cure reasoning.
Thus metaphysicians assist Nature indirectly by noninterference and directly by soothing fear and worry, by instilling faith, hope and confidence. Frequently they also aid Nature by prohibiting the use of tobacco, alcohol and pork, and by regulating otherwise the life and habits of their followers.
Let us consider the problem from another point of view. Let us assume, for argument's sake, that the average person passes in the course of a lifetime through a dozen different diseases. He recovers from eleven of these, no matter what the treatment. It is only the twelfth to which he succumbs. Yet, whosoever happened to treat the first eleven diseases claims to have cured them and, perhaps, to have saved the patient's life when, as a matter of fact, he recovered very often in spite of the treatment and not because of it.
These explanations account for the seemingly miraculous results of metaphysical healing. If healers and Christian Scientists were to explain their cures by the laws and principles of Nature Cure philosophy, mystery and miracle would be taken out of their business.
