No amount of elaborate studies of pathology and expensive examinations and laboratory tests ever leads to removal of cause. Every physician that a sufferer visits, diagnoses his disease differently, so that if he goes to twenty physicians he will have twenty diseases. Due to the prevailing misconceptions about disease, these examinations and tests lead to the treatment of symptoms and a total ignoring of causes. In the whole long list of methods of examining a patient there is not one of them that is, even remotely, a search for cause. Every one of them without exception, is a waste of time on effects, results, and end-products.
Nature has a habit of maintaining the integrity of the bloodstream at all costs.
Morphine given by hypodermic injection will be thrown into the stomach. Other poisons are thrown into other tissues. The real purpose of diagnosis should be to ascertain the causes of the effects present. When cause is found, it may be removed or corrected, and the effects will cease. When the true nature of disease and the essential unity of all so-called disease are understood, the conventional distinctions between 'diseases' lose their importance.
