Fiat + Fiat + Fiat."[65:3]

Every one is aware that it is a common experience to have an aversion for certain articles of food, and to be affected unpleasantly by the mere thought of them. Whereas, if a person partakes of such food without knowledge of it, no ill effects may ensue. The sense of taste is affected by the imagination. A man sent the cream from the breakfast-table because it tasted sour, but found it sweet when it was brought back by a servant, supposing it to be a fresh supply. A laxative medicine may produce sleep, in the belief that it is an opiate; and contrariwise, an anodyne may act as a purgative, if the patient believes that it was so intended.[66:1] Dr. Robert T. Edes, in "Mind Cures from the Standpoint of the General Practitioner," remarks that mental action, whether intellectual or emotional, has little or no effect upon certain physiological or pathological processes. Fever, for example, which is such an important symptom of various acute diseases, does not appear to be influenced by the imagination. Typhoid fever runs its course, and is not directly amenable to treatment by suggestion; but nevertheless hope, courage, and an equable mental condition do undoubtedly assist the vis medicatrix naturæ. The confident expectation of a cure is a powerful factor in bringing it about, doing that which no medical treatment can accomplish.

In recent works on suggestive therapeutics, the curative power of the imagination is emphasized and reiterated. "It is not the faith itself which cures, but faith sets into activity those powers and forces which the unconscious mind possesses over the body, both to cause disease and to cure it."[67:1]

Reference has been made to a certain similitude of religion and superstition. Oftentimes there appears to exist also a remarkable affinity between superstition and rheumatism, for these two are wont to flourish together, as in days of yore. Many a man of intelligence and education has been known to conceal a horse-chestnut in his pocket as an anti-rheumatic charm. A highly respected citizen, of undoubted sanity, was heard to remark that, were he to forget to carry the chestnut which had reposed in his waistcoat pocket for more than twenty years, he should promptly have a recurrence of his ailment.[67:2]

Daniel Hack Tuke, M.D., in referring to the systematic excitement of a definite expectation or hope, in regard to the beneficial action of totally inert substances, relates that a French physician, M. Lisle, especially recognized the efficiency of the imagination as a power in therapeutics. He therefore adopted the method of treating divers ailments by prescribing bread-pills, covered with silver leaf, and labelled pilules argentées anti-nerveuses. These pills were eagerly taken by his patients, and the results were highly satisfactory.

We may here appropriately cite one of several cases reported in the "British and Foreign Medical Review," January, 1847. A naval officer had suffered for some years from violent attacks of cramp in the stomach. He had tried almost all the remedies usually recommended for the relief of this troublesome affection. For a short time bismuth had been prescribed, with good results. The attacks came on about once in three weeks, or from that to a month, unless when any unusual exposure brought them on more frequently. Although the bismuth was continued in large doses, it soon lost its effect. Sedatives were given, but the relief afforded by these was only partial, while their effect on the general system was evidently very prejudicial. On one occasion, while suffering from the effect of some preparation of opium, given for the relief of these spasms, he was told that on the next attack he would be given a remedy which was generally believed to be most effective, but which was rarely used, owing to its dangerous qualities. Notwithstanding these, it should be tried, provided he gave his assent. Accordingly, on the next attack, a powder containing four grains of ground biscuit was administered every seven minutes, while the greatest anxiety was expressed, within the patient's hearing, lest too much be given. The fourth dose caused an entire cessation of pain, whereas half-drachm doses of bismuth had never procured the same relief in less than three hours. Four times did the same kind of attack recur, and four times was it met by the same remedy, and with like success! Dr. Tuke remarks that the influence of the mind upon the body, which is ever powerful in health, is equally powerful in disease, and this influence is exceedingly beneficial in aiding the vis medicatrix, and opposing the vis vitiatrix naturæ.

He dwells upon the remarkable power exerted by the mind "upon any organ or tissue to which the attention is directed, to the exclusion of other ideas, the mind gradually passing into a state in which, at the desire of the operator, portions of the nervous system can be exalted in a remarkable degree, and others proportionately depressed; and thus the vascularity, innervation and function of an organ or tissue can be regulated and modified according to the locality and nature of the disorder. The psychical element in the various methods comprised under psycho-therapeutics, is greatly assisted by physical means, as gentle friction, pointing, passes, et cetera."

At the siege of Breda, in the Netherlands, a. d. 1625, the Prince of Orange, son of William the Silent, availed himself of the "force of imagination" to cure his soldiers during a serious epidemic then prevailing among them. He provided his army surgeons with small vials containing a decoction of wormwood, camomile, and camphor. The troops were informed that a rare and precious remedy had been obtained in the East, with much difficulty and at great expense. Moreover, so great was its potency, that two or three drops in a gallon of water formed a mixture of wonderful therapeutic value. These statements, made with great solemnity, deeply impressed the soldiers, and their expectation of being cured was realized. For we are told that "they took the medicine eagerly, and grew well rapidly."[70:1]

Thomas Fuller, in the "Holy State," book iii, chapter 2, relates the following, which he styles a merry example of the power of imagination in relieving fatigue:

"A Gentleman, having led a company of children beyond their usuall journey, they began to be weary, and joyntly cried to him to carry them; which because of their multitude he could not do, but told them he would provide them horses to ride on. Then cutting little wands out of the hedge as nagges for them, and a great stake as a gelding for himself, thus mounted, Phancie put metall into their legs, and they came cheerfully home."
