The history of medicine is conjoined with the evolution of theology to an extent which makes them almost inseparable, and this may best be seen from a study of the management of the insane, which is a continuous record of cruelty based upon medico-theological superstition. Perhaps the most heartrending chapter of unphilosophical theology teems with the narration of thousands of unfortunate beings murdered, tortured, and mishandled by the finesse in the interpretation of Biblical texts. The greatest triumph of modern medicine has consisted in unfettering the views of effete centuries, born of superstition and misconception, and in placing the treatment of the insane upon a humane, often even a curative, plane. As other afflictions of humanity were attributed to the agency of evil spirits, this was particularly the case with insanity; for if the evil one found it an easy task to control the corporeal acts of humanity, his power over the mental functions of the person afflicted was even greater. Hence, it was not the person who acted, but the evil spirit in him. Thus, the devil and his minions were the specific pathogenic agents.

This conception was not universal, for history shows us that clear thinkers, far in advance of their times, had an almost correct view of the nature of insanity—namely, that it was due to an affection of the mind. Among such men were Hippocrates, Aretæus, Soranus, Galen, Aurelianus, etc., and some of the Mohammedan physicians. These apostles of science taught that insanity was a disease of the brain, and the most efficient remedy, mild, palliative treatment.

The belief which had flourished in most of the Oriental religions from remote antiquity, that the power of evil demons was the active cause of disease, particularly that lunacy was due to diabolic possession, became rooted in the early Christian Church and flourished for eighteen centuries, each leaf of this malignant plant representing countless unfortunates sacrificed to superstition. Later it was thought that the moon had a direct influence upon perturbation of the mind; hence, the term “lunacy” developed.

These doctrines gained special credence in the first centuries after Christ by the dissemination under the Church Fathers of the story of the miracles which they claimed had been performed by Jesus of Nazareth. Did not the Savior cast out devils? Did He not cure madness? The very word “epilepsy” shows by its derivation, ἐπίληψις (to seize upon), that possession was the presumable nature of the malady.

The noble work accomplished by the “pagan” pioneer alienists was discredited or forgotten, and the Church originated a process by which the possessed were to be treated. This method of treatment was derived purely from theologic sources, tempered with sufficient dogma. At first the treatment was gentle, in accordance with the spirit of the great physicians of antiquity, and if the afflicted one was not violent he was permitted to attend public worship. Sacred salves and holy water, the breath or the spittle of the officiating priest, the touching of relics, or a visit to holy places, were the principal therapeutic agents employed. These methods, even if they did no good (sometimes merely the consolation of a kind word from the priest had a beneficial effect), certainly did no harm, even tho such practises were factors in the spread of superstition.

This mild form of treatment did not, however, long continue. Soon measures were directed toward driving out the evil spirit from the possessed. This was attempted in various ways; first, by exorcism, in the period of Justin Martyr, and continued up to almost recent times (see Lecky, “History of European Morals”). “From the time of Justin Martyr for about two centuries, there is, I believe, not a single Christian writer who does not solemnly and explicitly assert the reality and frequent employment of this power.”

One of the chief attributes of the devil was pride, therefore attempts were made by exorcism to pierce this vulnerable point in the armor of the evil one, and the foulest, vilest epithets were used to attain this end. It is impossible to-day to print these expressions, even in a work of scientific character, and it is better, perhaps, to refer such as are especially interested in them to the Manuale Benedictionum, by the Bishop of Passau, published in 1849, and similar works. Adjuvants to this form of treatment consisted in “frightening” the devil by long words, difficult to pronounce, commonly derived from Oriental languages, by the administration of malodorous and filthy “drugs,” and similar practises.

It was claimed that many devils were thus driven out, and the annals of the Church contain numerous records of persons cured in this manner. “The Jesuit Fathers at Vienna, in 1583, glorified in the fact that in such a contest they had cast out twelve thousand, six hundred and fifty-two living devils” (White). The prevalence of these ideas to such a degree in the minds of the people may be noted from the fact that, in the churches themselves, such scenes are carved in stone and depicted on canvas. Medieval drama teemed with similar conceptions, and this condition of affairs prevailed for over one thousand years, unfortunately not in this harmless manner, but supplemented by great cruelty, which forms, perhaps, the most terrible chapter in the history of medical superstition.

The subtleties of theologic interpretation soon evolved a more comprehensive method of dealing with the “possessor” and the possessed. As an appeal to pride was ineffectual and noxious drugs unavailing, it was found necessary to whip the devil out, or the unfortunate individuals were imprisoned, and as a refinement of this treatment they were even tortured. Thus the jailer for a long time played the part of a specialist in lunacy, with the clergy in consultation. Places in which the insane were confined were known as “fool towers” and “witch towers.”

This state of things was not altered with the dawn of the Reformation. The writings of Luther conclusively show his ideas in regard to possession and witchcraft, and these views under Calvin reached enormous development. Even Cotton Mather, in many respects far in advance of his times, and who himself had known persecution, was not emancipated from these delusions, and Salem has many a story to tell of possession and witch-baiting. It is true we may quite properly consider these views as the thought of the times, but, in many other respects, Luther, Calvin, and Mather were in advance of their period, and, therefore, a justification for their actions is not quite apparent. Marcus Aurelius also was much superior to his age, yet was grateful to his teachers that they taught him to disregard superstition in all its various forms.
