The columnists and experts are all practicing allopathic social medicine. That something might be an antibiotic, radiation treatment, chemotherapy, or surgery. Medicine assumes that things can be fixed by observing symptoms, comparing the pattern of symptoms to known disorders and then taking the corrective action known in the past to cure the disease. The problem, as any medical doctor will readily admit, is that the allopathic model doesn't always work. Often, patients that are expected to live die and conversely.
Medication frequently makes the patient worse from side effects.
Patients almost always improve when prescribed placebos. Humans are just too complicated for even experts to predict what will happen all the time. The uncertainties of the allopathic model, acceptable in medical science, multiply exponentially in the social and spiritual realm. Behavior regarded as aberrant in one setting might be considered quite normal elsewhere. It would be difficult, if not impossible, except in the most obvious cases, to agree on the definition of a disease or its symptoms.
