than you have. Don't imagine that calling in the doctor is going to interfere with the natural course of the disease, or rob the patient of some chance he might have had of recovering by himself. On the contrary, it will simply give nature and the constitution of the patient a better chance in the struggle, probably shorten it, and certainly make it less painful and distressing.
If these symptoms of the summer fevers and fluxes are indicative of nature's attempts to cure, those of the winter's coughs and colds are no less clearly so. As we walk down the streets, we see staring at us in large letters from a billboard, "Stop that Cough! It is Killing you!" Yet few things could be more obvious to even the feeblest intelligence, than that this "killing" cough is simply an attempt on the part of the body to expel and get rid of irritating materials in the upper air-passages. As long as your larynx and windpipe are inflamed or tickled by disease-germs or other poisons, your body will do its best to get rid of them by coughing, or, if they swarm on the mucous membrane of the nose, by sneezing. To attempt to stop either coughing or sneezing without removing the cause is as irrational as putting out a switch-light without closing the switch. Though this, like other remedial processes, may go to extremes and interfere with sleep, or upset the stomach, within reasonable limits one of the best things to do when you have a cold is to cough. When patients with severe inflammations of the lungs become too weak or too deeply narcotized to cough, then attacks of suffocation from the accumulation of mucus in the air-tubes are likely to occur at any time. Young children who cannot cough properly, not having got the mechanism properly organized as yet, have much greater difficulty in keeping their bronchial tubes clear in bronchitis or pneumonia than have grown-ups. Most colds are infectious, like the fevers, and like them run their course, after which the cough will subside along with the rest of the symptoms. But simply stopping the cough won't hasten the recovery. Most popular "Cough-Cures" benumb the upper throat and stop the tickling; smother the symptoms without touching the cause. Many contain opium and thus load the system with two poisons instead of one.
Lastly, in the realm of the nervous system, take that commonest of all ills that afflict humanity--headache. Surely, this is not a curative symptom or a blessing in disguise, or, if so, it is exceedingly well disguised. And yet it unquestionably has a preventive purpose and meaning. Pain, wherever found, is nature's abrupt command, "Halt!" her imperative order to stop. When you have obeyed that command, you have taken the most important single step towards the cure. A headache always means something--overwork, under-ventilation, eye-strain, underfeeding, infection. Some error is being committed, some bad physical habit is being dropped into. There are a dozen different remedies that will stop the pain, from opium and chloroform down to the coal-tar remedies (phenacetin, acetanilid, etc.) and the bromides. But not one of them "cures," in the sense of doing anything toward removing the cause. In fact, on the contrary they make the situation worse by enabling the sufferer to keep right on repeating the bad habit, deprived of nature's warning of the harm that he is doing to himself. As the penalties of this continued law-breaking pile up, he requires larger and larger doses of the deadening drug, until finally he collapses, poisoned either by his own fatigue-products or by the drugs which he has been taking to deaden him against their effect.
In fine, follow nature's hints whenever she gives them: treat pain by rest, infections by fresh air and cleanliness, the digestive disturbances by avoiding their cause and helping the food-tube to flush itself clean; keep the skin clean, the muscles hard, and the stomach well filled--and you will avoid nine-tenths of the evils which threaten the race.
The essence of disease consists, not in either the kind or the degree of the process concerned, but only in its relations to the general balance of activities of the organism, to its "resulting in discomfort, inefficiency, or danger," as one of our best-known definitions has it. Disease, then, is not absolute, but purely relative; there is no single tissue-change, no group even of changes or of symptoms, of which we can say, "This is essentially morbid, this is everywhere and at all times disease."
Our attainment of any clear view of the essential nature of disease was for a long time hindered, and is even still to some degree clogged, by the standpoint from which we necessarily approached and still approach it, not for the study of the disease itself, but for
