As a consequence of this application of astrological knowledge to medicine, operations were performed only on certain favorable days or under favorable conjunctions of planets. An ailment that occurred at an unfavorable time, because of an unpropitious state of the heavens, would not be relieved until the motions of the stars brought a more benign conjunction. Observations seemed clearly to indicate that the stars actually had such influences. Even Hippocrates, though he insisted that "the medical art requires no basis of vain presumption, such as the existence of distant and doubtful factors, the {39} discussion of which, if it should be attempted, necessitates a hypothetic science of supra-terrestrial of subterrestrial belief,"
could not entirely get away from astrology. In his treatise on "Air, Water and Locality" he writes: "Attention must be paid to the rise of the stars, especially to that of Sirus as well as the rise of Arcturus, and after these to the setting of the Pleiades, for most diseases in which crises occur develop during these periods." In the second chapter he writes: "If anyone would be of the opinion that these questions belong solely in the realm of astrology, he will soon change his opinion as he learns that astrology is not of slight, but of very essential importance in medical art." (Personally I doubt the Hippocratean authorship of these pa.s.sages, but they are surely very old.)
The influence of the suggestions derived from astrology on human patients continued until almost the nineteenth century. There were many protests, especially from the Doctors of the Church, that the applications of astrology to medicine were false, but the practice continued. Both Kepler and Galileo drew horoscopes for patrons, and while Kepler doubted their value, he felt that in making them he was justified by custom. Galileo drew up the horoscope of the Grand Duke of Tuscany during an illness, and declared that the stars foretold a long life, but the Duke died two weeks later. But incidents of this kind did not disturb either popular faith or medical confidence in astrology as helpful, in prognosis, at least, if not also in diagnosis. Even so late as 1766 Mesmer was graduated at the University of Vienna, when it was doing the best medical work in Europe, with a thesis on "The Influence of the Stars on Human Const.i.tutions."
Later Astrology.--Few now realize that the curious figure printed at the beginning of most of our almanacs down to the present day is a relic of the time when physicians believed in the influence of the constellations over the various portions of the body. Even yet this idea has not entirely gone out of the popular mind, and hence its retention as something more than a symbol in our little weather books.
Man was considered as a little world, a microcosm, and the universe, as men knew it--the sun, the moon and the planets together--const.i.tuted a macrocosm. It was observed that the bodies const.i.tuting the universe were circ.u.mscribed in their movements and never went out of a particular zone in the heavens which was called the zodiac. This zodiac was divided into twelve equal parts called signs or constellations. Similarly man"s body was divided into twelve parts, of which each one was governed by a sign of the zodiac or by the corresponding constellation. The ram governed the head; the bull the neck; the twins the paired portions, shoulders, arms and hands; the crab the chest; the lion the stomach, and so on. The old surgical rule, as quoted by Nicaise in his edition of Guy de Chauliac"s "Grande Chururgie," was that the surgeon ought not make an incision, or even a cauterization, of a part of the body governed by a particular sign or constellation on the day when the moon was in that particular portion of the heavens, for the moon was supposed to be the bringer of ill-luck and to have untoward influences. The incision should not be made at these unfavorable periods for fear of too great effusion of blood which might then ensue. Neither should an incision be made when the sun was in the constellation governing a particular member, because of the danger and peril that might be occasioned thereby.
{40}
Such rules were supposed to be founded on observation. Patients were influenced by them mainly because they were a.s.sured that the surgical treatment was undertaken under the most favorable influence of the stars and that all unfavorable influences had been carefully observed and eliminated. It is hard for us to understand how such ideas could have been maintained for so long in the minds of men whose other attainments clearly show how thorough they were in observing and how profoundly intelligent in reaching conclusions. We should, however, have very little censure for them, since from some other standpoint we find every generation, down to and including our own, jumping at conclusions just as absurd and just as inconsequential. And the practice of astrology was not without its value, for the rea.s.surance given patients by the consciousness that the stars were favorable did much to relieve their anxiety as to the consequences of surgery, lessened shocks, hastened convalescence, and favored recovery.
HERBAL MEDICINE
What is thus exemplified in astronomy and astrology can be found in the story of every other science. After the knowledge of the stars, the next organized branch of information that might deserve the name of science related to plants. This, too, was introduced into medicine, and with more justification than astrology. Most of what was accomplished by early herbal medicine was, however, due to the influence produced on the mind rather than to any physical influence tending to correct pathological conditions. The shape and color of plants, their form, the appearance of their leaves, were all supposed to indicate medical applications for human ailments. The reason for their acceptance was entirely the ideas a.s.sociated with the plants and not any definite therapeutic effect. Whatever good nine-tenths of all the herbal medication accomplished certainly was by means of the influence on the mind. We have abandoned the use of most herbal remedies in recent years, even many that are still retained in the pharmacopeia, because we have realized their physical incapacity for good.
ALCHEMY
When chemistry, under the old name of alchemy, began to develop, its first study was of minerals, and just as soon as a body of knowledge was acquired chemistry was applied to medicine. All the investigators were engaged in searching for the philosopher"s stone, the substance by means of which it was hoped to change base metals into precious. It was generally believed that when this substance was found, it would have wonderful applications to human diseases and would trans.m.u.te diseased tissues into healthy tissues in the same way that it transformed metals. It was felt that the philosopher"s stone would be an elixir of life as well as a master of secrets for wealth. This would seem amusingly childish to us were it not for the fact that in radium we, too, seem to have discovered a philosopher"s stone--a substance that trans.m.u.tes elements. For some years after its discovery {41} we were inclined to think that it must have some wonderful application in medicine and in surgery, and we actually secured many good results until its suggestive value wore off.
The fact that much had been learned about chemicals persuaded men that they must be beneficial to human beings. Thus they were taken with confidence and produced good results. When our modern chemistry developed out of alchemy a great variety of drugs began to be used, and long, complex, many-ingrediented prescriptions were written.
Polypharmacy became such an abuse that the time was ripe for Hahnemann, whose principles, if carried to their legitimate conclusions, would require his disciples to give practically nothing to patients and treat them entirely by suggestion.
MATHEMATICAL MEDICINE
When mathematics developed, applications of that science were made to physiology and to medicine. Under the influence of Borelli, the school of Iatro-Mathematical medicine developed and it flourished long after him. Foster, in his "History of Physiology," says:
Borelli was so successful in his mechanical solutions of physiological problems that many coming after him readily rushed to the conclusion that all such problems could be solved by the same methods. Some of his disciples proposed to explain all physiological phenomena by mathematical formulas and hypotheses concerning forces and the shapes and sizes of particles.
MAGNETISM
Magnetism occupied a large place in the minds of the great thinkers of the sixteenth and seventeenth centuries. There is no doubt that Paracelsus accepted, quite literally, what we embody in figurative expressions with regard to magnetism. To him the attraction of s.e.x was magnetic. People had personal magnetism because they possessed physical powers by which they attracted others. He considered that these powers of attraction were expressions in human beings of the power of the magnet in the physical world, and that the two were literally equivalents. Kepler, one of the deepest thinkers of his time, evidently entertained the idea that the magnet represented the soul of the physical world, and that the planets were held in connection with the sun and their satellites with the planets, by magnetic attraction. We now call it the attraction of gravitation. We understand the force no better than before, but have changed the terms. Descartes theorized much along magnetic lines, and felt that by the use of certain expressions he was adding to knowledge, though he was really only multiplying terms.
Human Magnetism.--How seriously the question of human magnetism was taken will perhaps be best appreciated from one old fallacy. For a long period it was supposed that human beings were so highly magnetic that if a man were exposed in an open boat, in perfectly calm weather, in the open sea, where no currents would disturb him, his face would turn to the north, under the same magnetic influences as caused the needle to point to the north! Many studies of magnetism were made at this time, so that the subject {42} attracted widespread attention.
Columbus had made some rather startling observations on his voyage to America with regard to the declination of the magnetic needle, and, during the century following, Norman and Gilbert made interesting studies in the same subject. Father Kircher wrote two books on magnetism and there were a number of others written by university professors. Advantage was taken of this thoroughly scientific interest in magnetism to erect a whole body of pseudo-scientific medicine supposed to be founded on magnetic principles. The same theories were also applied to supposed explanations of various psychological phenomena.
During the sixteenth and seventeenth centuries the application of magnets was a favorite treatment for a great many diseases. Especially were they useful in the treatment of muscular pains and aches and the chronic diseases which so disturbed men"s minds. Many of the joint troubles of the aged, the muscular pains and aches that develop from the wrong use of muscles, and the vague internal discomforts which often disturb men so seriously, were cured by the application of magnets. Perkins" success with his tractors shows how much can be accomplished in this way.
ELECTROTHERAPY
The great development of pseudo-science in medicine remained for the era following the scientific investigation of electricity. With the discovery of the Leyden jar and its startling spark, a new and marvelous healing agent seemed to be at hand. It is quite amusing to read the accounts of the influence of the spark of the Leyden jar on the well and on the ailing. In my "Catholic Churchmen in Science"
(Dolphin Press, Phila., 1909) I summed up the situation.
Winckler of Leipzig said that the first time he tried the jar, he found great convulsions by it in his body; it put his blood into great agitation; he was afraid of an ardent fever, and was obliged to use refrigerating medicines. He felt a heaviness in his head as if a stone lay upon it. Twice it gave him a bleeding at the nose.
After the second shock his wife could scarcely walk, and, though a week later, her curiosity stronger than her fears, she tried it once more, it caused her to bleed at the nose after taking it only once.
Many men were terrified by it, and even serious professors describe entirely imaginary symptoms. The jar was taken around Europe for exhibition purposes, and did more to awaken popular interest than all the publications of the learned with regard to electricity, in all the preceding centuries.
The extent to which the curative power of electric sparks from the Leyden jar was supposed to go is best appreciated from a list of the affections that one distinguished electro-therapeutist claimed could be not only benefited, but absolutely cured by its employment. It included pulmonic fever, under which t.i.tle practically all the more or less acute diseases of the chest were included, and some at least of the sub acute; dropsy, by which was meant every effusion into the abdominal cavity no matter what its cause; dysentery, under which was included at that time not only the specific dysenteries but many of the summer complaints and some typhoid fevers; diarrhea, including all the intestinal diseases not already grouped under dysentery; putrid and bilious fever, under which category were a.s.sembled the worst cases of typhoid; typhus {43} fever, and all the other continued fevers, and any febrile condition reasonably severe for which no other term could be used; epidemic diseases, pest, anthrax, small-pox, cancer, gravel, diseases of the bladder and of the brain and spinal cord. The Leyden jar had no real effect on any of these affections, but doubtless the mental effect of this new remedy was quite sufficient to be of distinct therapeutic value in the milder forms of many of them.
With Galvani"s discovery of the twitching of the muscles of the frog there came a new impetus to the exploitation of electricity in medicine. Many felt that now it was beyond doubt that electrical energy bore some definite relation to vital energy--that one might be made to replace the other if indeed they were not more or less the same thing. This led to many applications of electricity in medicine.
Students of physiology were convinced that they were getting close to the solution of the mystery of life, and their persuasion was readily carried over to the people of the time, so that electricity literally worked wonders on them.
When the various electrical machines were invented and their use popularized, pseudo-science proceeded to exploit them, and succeeded, because the mechanical shock of the electric current proved a suggestive therapeutic stimulant. Gordon in the eighteenth century made the first practical frictional electrical machine, and soon some men were observing wonderful effects with it, though the charge was so small that it could actually accomplish little. Just after the invention of the voltaic pile in 1800 it came to be used in medicine with wonderful results. We are p.r.o.ne to think that electrotherapy is modern, but when electrical machines were quite crude, current strength small and potential low, old-time electro-therapeutists were recording their wonderful results and were getting just as marvelous effects as are reported now by enthusiasts. Considerable electro-medical literature existed a century ago when next to nothing was known of electricity. When, later, high potency currents came in and the Wimshurst and other powerful machines were invented, there was revealed at each novel invention a new horizon in electro-therapy and wondrous cures were reported. These continue to occur in the practice of a few favored individuals, though the general profession secures only some ordinary mechanico-muscular effects, which demand much time for real good to be accomplished and have nothing at all of the marvelous about them.
The power of the pseudo-scientific aspect of electricity to influence patients, far from being lost in our time, has rather been increased.
Our newspapers make their readers eminently suggestible because they constantly furnish suggestions, and nothing so strengthens a function of any kind as exercise of it. All sorts of electrical contrivances and apparatuses are advertised to cure various pains and aches. Many of them actually seem to relieve long-standing discomfort, though it is not through any electrical power that they do so, but entirely through their influence on the patient"s mind. A museum of the electrical contrivances of various kinds for which absurdly high prices are paid at the present time and which people recommend to others because of having been benefited by them would be interesting.
There are belts of many kinds, and rings, and medallions, and plates to be worn on the back and on the chest, and curiously shaped poles or "polar plates" resembling various organs, and pendants and armlets and anklets and insoles of many, many kinds, usually {44} going in pairs, one made in zinc and the other in copper, and worth exactly as much as the weight of copper and zinc in them, yet curing chronic ailments by suggestion, or at least bringing relief from many pains and aches complained of.
LIGHT AND PSYCHOTHERAPY
Just as electricity has always been therapeutically abused by those who have taken advantage of the suggestive influence of its marvelous energy, so each new discovery in light has been the source of pseudo-scientific applications to medicine. When the explanation of photography was first made, shortly after the middle of the nineteenth century, and it was demonstrated that it was the blue light, or at least that end of the spectrum, and even some of the rays beyond the visible violet, which were the most active in this regard, applications of this fact to popular medicine became the order of the day. We had a wave of "blue light therapy" that wandered over this country and sold tons of blue gla.s.s. People simply sat beneath the blue gla.s.s as the sun shone through it and were supposed to absorb the actinic rays and acquire new life. According to many who had tried them, the ultra-violet rays were quite equal in their power to heal and restore new vigor to old frames to the fabled elixir of life of the olden time. "Rheumatism (that universal ill of the unthinking) in all its hydra-headed forms disappeared," as one enthusiast declared, "before the blue light, like the mists of the morning before the sun."
All this, though it is said that the movement had no more serious foundation than the desire of a manager of a gla.s.s factory, who found himself stocked up with blue gla.s.s through a mistake, to dispose of his surplus stock. He not only did so, but many other manufacturers turned special attention to the new product because of the demand for it. The newspaper advertising was through the reading columns. The results were heard of on every side.
THE X-RAY
That happened two generations ago, and it might be supposed that in the meantime there had been so much advance in popular education, and particularly in the diffusion of scientific knowledge, that such a self-deception on the part of scientists, and blind following by the people, could not take place in our time. Just as soon as Roentgen discovered the X-ray, however, we began to have applications of that wonderful agent to curative purposes. About 1900, scarcely five years after Roentgen"s discovery, there was hardly an ailment that some one did not claim to have seen treated successfully by the X-rays.
Especially was this true for the chronic and hitherto supposedly incurable diseases. All the forms of malignant disease were treated by the new agent, and some supposedly marvelous cures were reported.
Everything chronic was favorably affected--lupus, rodent ulcer, eczema, acne rosacea, even tuberculosis of the lungs. At the time I was on the staff of a medical journal, and the favorable reports came in so thick and fast that it really looked for a time as though the surgery of the future was to be much simplified. It took but a year or two to show us how little of lasting therapeutic benefit there was {45} in the X-ray, in spite of the fact that it is a marvelous agent in its action upon living tissues. At the present moment it is used comparatively little, and its use is gradually diminishing, except for very special limited affections.
RADIUM AND RADIO-ACTIVITY
When radium was discovered, though it came so soon after the discovery of the X-ray and our disappointment with it, the old story of another pseudo-scientific medical application was told. For a time it looked as though radium might accomplish all that had been promised for the X-ray, though that promise had been so lamentably broken. Then, besides radium, we had brought home to us the whole cla.s.s of radio-active substances, and their possibilities. The internal administration of radio-active liquids was one of the hopes of therapeutics. We had found it difficult to explain how many of the mineral waters produced the beneficial action credited to them when taken at the spring. We knew that artificially made waters of exactly the same chemical composition, so far as we could determine, did not have the same effect, nor even the waters themselves when taken at a distance from the spring.
With the discovery of the radio-active principle there came the suggestion that possibly the main virtue of mineral waters at the spring was due to radio-activity. This would not be present in artificial water and would disappear from the natural water during shipment. This new idea was alluring, and it captured many. Radium seemed to be the new panacea. But we are discovering its limitations.
It is of little avail in surgery; it is probably of less avail in medicine. As yet, however, we cannot say absolutely and must wait until results are determined. In the mean time many zealous advocates of the marvelous power of radio-activity to cure are exploiting it, apparently getting results and certainly making money. In the case of the mineral waters, also, the most important therapeutic element is probably the mental influence, which is strongest at the spring itself, where the suggestion of efficiency is repeated many times a day, and where the very atmosphere breathes confidence in the results to be obtained.
SUGGESTION AND PSEUDO-SCIENCE
These applications of science, or rather of supposed science, ill.u.s.trate the influence of suggestion. The succession of events in each case is about as follows: The definite att.i.tude of mental expectancy is created in the popular mind. As a consequence, with the application of the new scientific principle, patients cease inhibiting the recovery that would have come spontaneously before, only that they were self-centered and had their nervous energies short-circuited.
Some are benefited by the habits of life that are established as a consequence of the belief that they are about to be cured, while before this they had been largely confining themselves to their houses, and had been refusing to take recreation or get diversion because of the conviction that they were ill. Finally, many of them had no real physical ills, but were suffering from mental ailments brought on by dreads and by a concentration {46} of attention on certain portions of the body which interfered with the normal physiologic action of those parts. Whenever strong mental impressions are produced, from any cause, results will surely follow, some of them marvelous. The supposed causes of these results will seem quite absurd to those who study them afterwards, but they were living realities to the sufferers. Nothing is more calculated to produce a strong mental impression than a newly discovered scientific fact with some supposedly wonderful application to humanity. The subsequent history of the application of scientific discoveries to medicine has been as invariably the same as the primary enthusiasm over each new therapeutic agent. After a time some people were not benefited.
Physicians lost confidence in the power of the new remedial measure, whatever it might be. Patients were no longer impressed by the a.s.surance that they would be benefited, and then the new application has either completely disappeared from our list of remedies, or has remained only to be used by a few, who still report good results from it. In spite of the constancy of this succession of events, we are still quite ready to take up with enthusiasm new discoveries in science and their applications to medicine. We have not yet lost the feeling, common in earlier centuries, that all science was meant for man and that every new scientific development must have some special reference to him.
