Human spoken language seems to be

After hearing much from his patients about alleged faith-healing, a Minnesota physician named William Nolen spent a year and a half trying to track down the most striking cases. Was there clear medical evidence that the disease was really present before the ‘cure’? If so, had the disease actually disappeared after the cure, or did we just have the healer’s or the patient’s say-so? He uncovered many cases of fraud, including the first exposure in America of ‘psychic surgery’. But he found not one instance of cure of any serious organic (non-psychogenic) disease. There were no cases where gallstones or rheumatoid arthritis, say, were cured, much less cancer or cardiovascular disease. When a child’s spleen is ruptured, Nolen noted, perform a simple surgical operation and the child is completely better. But take that child to a faith-healer and she’s dead in a day.
