Another branch of Mental Healing is seen in the modern schools of the "New Thought," "Mental Science," "Christian Science," and the "Emmanuel Movement." The authorities generally agree upon tracing the rise of these several schools to the general interest in the subject manifested in the United States and Great Britain about the middle of the last century. Some of the authorities believe that this general interest was induced largely by the teachings of Charles Poyen, a Frenchman who came from France to New England about 1835, bringing with him the French teachings and theories regarding mesmerism and the phenomena allied thereto. Poyen's teachings attracted marked interest and attention, and he soon had a host of followers, students and imitators. Teachers of the "new science" sprang up on all sides. Many theories were evolved and actively supported by the adherents of the several prominent teachers. The rise of interest in phrenology and the dawning interest in spiritualism aided the spread of the new teachings regarding mesmerism, clairvoyance, psychic healing, etc., and the pages of many magazines and books published about that time show that a public taste had been created for the strange and mysterious. Dr. J. S. Grimes, a physician interested in phrenology, taught that the phenomena were due to the action of a strange atmospheric force which he called "etherium." Rev. J. Bovee Dods evolved a theory based upon the supposed existence of an electrical principle, and called his system "Electro-Biology," by means of which he attracted to himself a large following. Dods wrote several large books on the subject, and traveled on lecture tours in this country and Great Britain, arousing great enthusiasm and making many cures. Rev. Leroy Sunderland expounded the doctrine of "patheism," in which he combined a strange mixture of mysticism and what has since been called "suggestion," to which he afterward added the current teachings of spiritualism after his conversion to that philosophy. It would seem that credit should be given Sunderland for his early announcement of the principle of suggestion, for he said: "When a relation is once established between an operator and his patient, corresponding changes may be induced in the nervous system of the latter by mere volition, and _by suggestions addressed to either of the external senses_." The decade, 1840-1850 witnessed a remarkable interest in psychic phenomena of all kinds, and during that time there was undoubtedly laid the foundations upon which the later structures have since been erected. Any one reading the short stories of Poe, and other writers of that period, may readily see the state of public interest in these subjects at that time.
