James Walsh - Psychotherapy

His greatest successor among the Arab physicians, Avicenna (eleventh century), "the Hippocrates and the Galen of the Arabians," as Whewell called him, has some striking tributes to what he recognized as the influence of the mind on the body. He appreciated that not only might the mind heal or injure its own body, but that it might influence other bodies, through their minds, for weal or woe. He says: "The imagination of man can act not only on his own body, but even on other and very distinct bodies. It can fascinate and modify them, make them ill or restore them to health." In this, of course, he is yielding to the dominant mystical belief that man can work harm to others, which subsequently, under the name of witchcraft, came to occupy so prominent a place for ill in European history. But at the same time it is evident that his opinions are founded on his knowledge of the influence of mind on body, as he had seen its action in medicine. From him we have the expression: "At times the confidence of the patient in the physician has more influence over the disease than the medicine given for it."

During the Middle Ages faith was one of the things most frequently appealed to, and even the physicians made use of religious belief to secure a favorable attitude of the patient's mind toward the remedies. One of the men who particularly realized the importance of this was Mondeville, the great French surgeon.

Pagel has called attention to Mondeville's insistence on preparing the patient's mind properly for venesection. The patient should be made to feel that this procedure was sure to do him good, and various reasons should be given him why the removal of a certain amount of blood carried with it poisons from the body, and so gave a better opportunity to nature to conquer the disease. If the patients were unfavorably disposed towards venesection, Mondeville thought that it should not be performed, as it was not likely to do good. It was not that he felt that the mental influence was the more important of the two therapeutic factors, but that a combination of the remedial force of blood-letting with a favorable state of the patient's mind meant so much more than could be accomplished by venesection alone that it was worth while to take pains to have the combination of the two. We in modern times realize that in most cases blood-letting rather did physical harm than good. It continued to hold a place in medicine because patients were so much impressed by it that they were given renewed vigor after its use.

What is exemplified in medieval medicine in this matter remains true during the Renaissance. In the fifteenth century Petrus Pomponatius, well known as a thinker and writer on borderland subjects related to medicine, came to the conclusion that men might very well be cured of certain ailments by influence from the minds of others, and that such treatment, undertaken by physicians appropriately endowed, produced wonderful effects. He said:

Some men are specially endowed with eminently curative faculties; the effects produced by their touch are wonderful: but even touch is not always necessary; their glances, their mere intention of doing good are efficient for the restoration of health. The results, however, are due to natural causes.

Paracelsus.—Paracelsus, the great physician of the first half of the sixteenth century, who may well be considered the father of modern pharmaceutics, had no illusions with regard to the exclusive power of drugs over disease. He recognized that mental influence was extremely important, and often lent a power not otherwise possessed to many remedies. He said:

Imagination and faith can cause and remove diseases. Confidence in the virtue of amulets is the whole secret of their efficacy. It is from faith that imagination draws its power. Anyone who believes in the secret resources of Nature receives from Nature according to his own faith; let the object of your faith be real or imaginary, you will in an equal degree obtain the same results.

Personal magnetism, in the sense in which we now use it, a transference of the idea from the science of magnetics as related to the phenomena of the magnet, seems to have originated with Paracelsus. He was sure that the influence exerted over certain patients by certain physicians was due to a force very like that exerted by the magnet over iron. He was even inclined to think that magnets themselves might exert a strong potency over diseased conditions, and he found them to be useful in epilepsy. Doubtless in many cases of supposed epilepsy successfully treated the ailment was really of an hysterical nature. In these cases the strong suggestion which the use of the magnets gave for many centuries acted favorably.

Agrippa.—The writings of Cornelius Agrippa, a contemporary of Paracelsus, and, like him, a student of alchemy and of the secrets of nature, contain corresponding passages which serve to show how much of interest there was in mental influence during the Renaissance. All of these men were, of course, a little outside of the ordinary medical tradition, intent on getting to realities, not being satisfied either with words or assumptions, refusing to accept many thing that the physicians of their time completely credited. Agrippa in a characteristic passage said:

Our mind doth effect divers things by faith (which is a firm adhesion, a fixed intention, and a vehement application of the worker or receiver) in him that coöperates in anything, and gives power to the work which we intend to do. So that there is made in us, as it were, the image of the virtue to be received, and the thing to be done in us, or by us. We must, therefore, in every work and application of things, affect vehemently, imagine, hope and believe strongly, for that will be a great help.

Van Helmont.—At the end of the sixteenth century Van Helmont, who carried on the work in pharmaceutics begun by Paracelsus, and to whom we owe the discovery of a number of substances commonly used, as well as the invention of the word "gas," was a thorough believer in the influence of mind over body and, indeed, in the existence in human beings of storehouses of latent energy ordinarily unemployed, but that might under special circumstances be tapped to produce wonderful effects. Indeed, some passages remind us of Prof. James' expressions in his discussion of the law of human energy. Van Helmont said:

All magical power lies dormant in man, and requires to be excited. (Compare Prof. James's "Law of Mental Energy" in the chapter on Mental Influence). This (need for excitation) is particularly the case if the subject upon whom we wish to operate is not in the most favorable disposition; if his internal imagination does not abandon itself entirely to the impression we wish to make upon him; or if he towards whom the action is directed possesses more energy than he who operates. But when the patient is well disposed or weak, he readily yields to the magnetic influence of him who operates upon him through the medium of his imagination. In order to operate powerfully, it is necessary to employ some medium; but this medium is nothing unless accompanied by internal action.

Sydenham.—In the more modern period the deliberate use of the influence of the mind on the body is quite as clear. Undoubtedly the greatest of modern physicians, who well deserves the name of the English Hippocrates, is Sydenham. How much Sydenham realized that many of his patients' ailments could only be cured by occupying their minds with other things is seen in his writings. There is a characteristic story told by Dr. Paris in his "Pharmacologia" which illustrates this well and is a striking anticipation of what we are prone to think of as very modern views in these matters:
